Background technology

The structure of existing rocking chair is to be provided with central shaft on base, and seat is hinged on the central shaft top, generally rocks back and forth, and all is used in the life, can not be military affairs, scientific research, industry.

Summary of the invention

Technical problem to be solved by this invention provides a kind of universal swinging all around and simple in structure, easy to use, the universal swinging chair of low cost of manufacture.

In order to solve the problems of the technologies described above, universal swinging chair provided by the invention, comprise base, central shaft and seat, described seat is installed in the top of described central shaft by the multi-directional ball joint, on described base, be provided with first cam and second cam that central axis intersects vertically mutually, on described base, be provided with the linkage that rocks back and forth, described linkage one end that rocks back and forth is connected with described first cam drive by the roller bearing pin, the other end and the corresponding transmission of described seat, on described base, also be provided with the linkage of vacillating now to the left, now to the right, described linkage one end of vacillating now to the left, now to the right is connected with described second cam drive by the roller bearing pin, the other end and the corresponding transmission of described seat, the reduction box that on described base, is provided with motor and is in transmission connection with it, the output of described reduction box is connected with couple axle, described second cam is installed on the described couple axle, and described couple axle end is connected with described first cam drive by bevel gear.

On described base, be provided with the case that described multi-directional ball joint, central shaft, first cam, second cam, the linkage that rocks back and forth, the linkage of vacillating now to the left, now to the right, motor, reduction box and couple axle are covered.

Adopt the universal swinging chair of technique scheme, motor and reduction box drive first cam by couple axle and second cam rotates, when first cam and second cam rotate, the roller bearing pin rolls in the cam path of first cam and second cam, the linkage that rocks back and forth is swung up and down with the linkage of vacillating now to the left, now to the right, thereby make seat on the multi-directional ball joint, form universal swinging.When the present invention used, technical parameter carried out the frequency conversion seat and has different angles and speed according to the rules.

In sum, the object of the present invention is to provide a kind of universal swinging all around and simple in structure, easy to use, low cost of manufacture, processing and manufacturing is easy, universal swinging chair easy for operation.Be that a motor carries out work, simple in structure, the whole dependable performance of waving is applicable to military affairs, scientific research, industry, civilian as one.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, central shaft 9 is installed on the base 1,seat 8 is installed in the top of central shaft 9 bymulti-directional ball joint 10, on base 1, be provided withfirst cam 3 andsecond cam 11 that central axis intersects vertically mutually, on base 1, be provided with thelinkage 6 that rocks back and forth,linkage 6 one ends that rock back and forth are in transmission connection by the roller bearingpin 5 andfirst cam 3, the other end andseat 8 corresponding transmissions, on base 1, also be provided with thelinkage 7 of vacillating now to the left, now to the right,linkage 7 one ends of vacillating now to the left, now to the right are in transmission connection by the roller bearing pin andsecond cam 11, the other end andseat 8 corresponding transmissions, thereduction box 13 that on base 1, is provided withmotor 14 and is in transmission connection with it, the output ofreduction box 13 is connected withcouple axle 12,second cam 11 is installed on thecouple axle 12,couple axle 12 ends are in transmission connection by thebevel gear 4 andfirst cam 3, are provided with on base 1multi-directional ball joint 10, central shaft 9,first cam 3,second cam 11,linkage 6 rocks back and forth, thelinkage 7 of vacillating now to the left, now to the right,motor 14, thecase 2 thatreduction box 13 andcouple axle 12 cover.

Referring to Fig. 1,motor 14 andreduction box 13 drivefirst cam 3 bycouple axle 12 andbevel gear 4 andsecond cam 11 rotates, whenfirst cam 3 andsecond cam 11 rotate, the roller bearing pin of thelinkage 6 and thelinkage 7 of vacillating now to the left, now to the right of rocking back and forth rolls in the cam path offirst cam 3 andsecond cam 11 respectively, thelinkage 6 that rocks back and forth is swung up and down with thelinkage 7 of vacillating now to the left, now to the right, thereby makeseat 8 onmulti-directional ball joint 10, form universal swinging.When the present invention used, technical parameter carried outfrequency conversion seat 8 and has different angles and speed according to the rules.
