Abstract

The utility model relates to a spring structure for supporting a metal bed. The spring comprises a plurality of metal rings. The plurality of metal rings of the spring form a necking down part at least. At least a portion of the necking down part is arranged at the bottom of the spring. Due to the adoption of the spring structure, the structure of the spring is changed and the necking down part can effectively disperse and release the pressure brought by the weight on the bed and prevent the deformation of the spring used for a long time.

Description

A kind of spring structure that is used for the support of metal bed

Technical field

The utility model relates to spring structure, a kind of spring structure that is used for the metal bed of saying so exactly, and this spring structure can carry out the dispersion of power effectively, particularly bears slow the pressure and indeformable.

Background technology

Spring is a kind of articles for use of often being used in daily life, and particularly in the used bed of the daily daily life of people, spring has played important supporting role.

Usually, bed comprises a body and mattress, in wooden bed body, is not need spring, just by frame structure mattress is supported, and by the spring in the mattress human body is supported; The metal bed then generally with mattress and the bed body spring that combines, supports human body by spring.

These are used for the spring of mattress, adopt any one of common independent spring, chain spring, open spring or pocket type spring usually, and common independent spring is the most traditional a kind of spring.Its basic structure is served as reasons and is worn the column monomer groups of springs of remaining silent that the spring steel wire is connected; The feature of chain spring is the continuous groups of springs that is passed by a steel wire, is the product of spring bed core large-scale production.Its basic structure is formed by connecting by wearing the spring steel wire by the three-dimensional steel filament that curls up continuously.Its advantage is the production efficiency height, and the steel wire cost is greatly enlarged the bosom, and the spring integral, flexible is better.

The birth sign implantation core manufacturing philosophy of open spring changes to the direction of " people first ".Its basic structure is served as reasons and is worn the opening monomer groups of springs that the spring steel wire is connected.Because the opening of monomer spring collar extension, though its connected mode still connects for wearing the spring steel wire, the elasticity free degree of monomer spring greatly increases.Its advantage is that the people shows consideration for and spends better resilient enough.

The pocket type spring is the most representative at present a kind of spring bed core.It has abandoned traditional spring connected mode of wearing, and is formed by connecting by the opening monomer spring cloth bag of packing into.Its connected mode transfers to by being rigidly connected and flexibly connecting.The change of connected mode can both not involve each monomer spring each other according to the free resilience of the pressure that is carried.Its advantage be the people show consideration for and spend fabulous, monomer spring independent support, two people crouch to lie and do not disturb mutually.

But these springs have a common characteristic, and being exactly spring is made of the ring of unified diameter, therefore causes stressed bearing plane narrow, and long-term pressurized easy deformation is born slow ability of pressing.

The utility model content

Based on this, provide a kind of spring structure that the metal bed supports that is used for order of the present utility model, this structure is improved spring structure in conjunction with the characteristics of metal bed, makes spring have better elastic, and long-term pressurized can not be out of shape.

For reaching above-mentioned order ground, the utility model is achieved in that

A kind of spring structure that is used for the support of metal bed, this spring comprises a plurality of beckets, it is characterized in that constituting a necking section at least in described a plurality of beckets of spring, and described necking section at least a portion is positioned at the bottom of spring.

By this spring structure, with the structural change of spring, necking section can disperse the slow pressure that weight is brought on the body effectively, avoids the long-term camber of spring phenomenon of bringing of using.

Described spring, its necking section are positioned at the spring bottom, are at least 1/3rd of spring length.

Described necking section, it is a pyramidal structure, and the minimum metal ring diameter is not less than 1/3rd of maximum metal ring diameter.The suitable intensity that keeps necking section like this helps forming and supports.

Described necking section, be arranged at the upper and lower of spring, the a plurality of beckets in centre that are spring are column structure, and a plurality of beckets on spring top are the pyramidal structure of diameter reduction gradually that makes progress, and a plurality of beckets of spring bottom are downward diminishing pyramidal structure.

Described spring, the becket of its topmost are the becket of diameter maximum, and from the top down, the diameter of becket dwindles gradually.

Described spring, its a plurality of beckets are made for the manganese steel material.

The utility model adopts above-mentioned version, change the spring structure design of original simple column, the structure of spring is changed, can carry out the dispersion of power effectively, make spring have the effect that disperses slow pressure, can use indeformable for a long time as supporting role.

Description of drawings

Fig. 1 is the structural representation of embodiment one of the present utility model,

Fig. 2 is the structural representation of embodiment two of the present utility model,

Fig. 3 is the structural representation of embodiment three of the present utility model.

The specific embodiment

Below, in conjunction with the accompanying drawings shown in, concrete enforcement of the present utility model is elaborated.

Shown in Figure 1, be first kind of embodiment of the utility model, in this embodiment, thebecket 10 diameter maximums in the top, the diameter that constitutes the becket of spring from the top down dwindles successively, formnecking section 11,, form pyramidal structure like this untilbottom becket 12 diameter minimums.

In loading process, the power that thetop becket 10 is born in downward transmittance process, along with the becket diameter variation, is disperseed power gradually, can avoid the concentrated of power to press down, and has avoided memory function that common spring has poor, the defective of easy deformation.

In actual fabrication, adopt the spring of the above-mentioned making of falling the pyramidal structure, if be made as the structure of 10 beckets, highly be 220mm.Uppermost becket diameter is 75mm, and nethermost becket diameter is 32mm, and it is that the manganese steel of 2.3mm is made that becket adopts diameter, can bear 1 ton slow pressure and indeformable.

Shown in Figure 2, be the structural representation of second kind of embodiment of the utility model.Shown in the figure, the top of spring is column structure, the diameter that is top 7 beckets is consistent with the diameter of thetop becket 20, be 75mm, below three beckets be diminishing diameter form, thereby constitute thenecking section 21 of a bottom, the minimum of thebecket 22 of foot, its diameter is 32mm.

This version also can reach the technique effect that embodiment shown in Figure 1 has.

Figure 3 shows that the structural representation of the third embodiment.Have two necking sections among the figure, specifically, in this embodiment, spring has 10 beckets altogether, middle twobecket 30 diameter unanimities, frombecket 30 upwards, the diameter of becket dwindles gradually, form necking section 1, through the transition of three rings, untiltop metal ring 32; Downward frombecket 30, the diameter of becket dwindles gradually, forms necking section 2 33, through the transition of three rings, untilbottom metal ring 34, wherein the diameter ofbecket 30 is 75mm, the diameter ofbecket 32 andbecket 34 is 32mm, and the height of spring is 220mm, forms a wooden club shape structure, this version, the Memorability of spring is good, can bear 1 ton slow pressure, after pressure disappears, spring can resile at once, can not be out of shape.
