Technical field

The utility model relates to the computer desk technical field, especially a kind of computer desk post lifting locking device.

Background technology

The lifting of existing computer desk post has mechanical type, vapour-pressure type etc.The disadvantages such as mechanical type exists complex structure, and wearing and tearing are large, and service life is short; The disadvantages such as there is temperature influence in vapour-pressure type, and operating pressure is unstable, and gases at high pressure are easily revealed, and dry friction occurs in inside, and is fragile.Traditional locking mechanism usually can not provide enough little adjustment amount or can not guarantee reliably the height of computer desk.

The utility model content

In order to overcome the deficiency of existing technology, the utility model provides a kind of computer desk post lifting locking device.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of computer desk post lifting locking device, comprise two semicircle fixed mounts, main body, contractibility, pull bar, slide block, spring and alignment pin, the pull bar bottom connects contractibility, two semicircle fixed mounts are enclosed in respectively the main body two ends and form a cylinder, contractibility, pull bar, slide block, spring, alignment pin all is positioned at cylinder, pull bar passes main body and spring connects contractibility, the latter half of main body is provided with a cavity, alignment pin passes the dowel hole of bottom part body, and the locating hole on the slide block, slide block is fixed in the cavity; Main body bottom outer wall is provided with a ring annular groove, and the slide block lower semisection is provided with the groove of accepting mutually with annular groove, and semicircle fixed mount inwall is provided with ring tooth, and slide block is provided with the knuckle-tooth that matches with ring tooth.

According to another embodiment of the present utility model, comprise that further described locating hole is greater than dowel hole.

The beneficial effects of the utility model are that the utility model structure is simple, and is easy to use, can be installed in the table pillar of study table, desk, computer desk etc., regulates the height of locking desk.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the explosive view of the utility model structure;

Fig. 2 is the assembling schematic diagram of the utility model internal structure;

Among the figure, 1, semicircle fixed mount, 2, main body, 3, contractibility, 4, pull bar, 5, slide block, 6, alignment pin, 7, spring, 8, knuckle-tooth 9, ring tooth, 10, locating hole, 11, cavity, 12, annular groove, 13, dowel hole, 14, groove.

The specific embodiment

Such as Fig. 1, shown in Figure 2, a kind of computer desk post lifting locking device, comprise two semicircle fixedmounts 1,main body 2,contractibility 3,pull bar 4,slide block 5, spring 6 andalignment pin 7, pullbar 3 bottoms connectcontractibility 4, two semicircle fixedmounts 1 are enclosed in respectivelymain body 2 two ends and form a cylinder,contractibility 4,pull bar 3,slide block 5, spring 6,alignment pin 7 all is positioned at cylinder,pull bar 4 passesmain body 2 and spring 6 connectscontractibility 3, the latter half ofmain body 2 is provided with a cavity 11,alignment pin 7 passes thedowel hole 13 ofmain body 2 bottoms, and the locatinghole 10 on theslide block 5,slide block 5 is fixed in the cavity 11;Main body 2 bottom outer walls are provided with a ring annular groove 12, andslide block 5 lower semisections are provided with the groove 14 of accepting mutually with annular groove 12, and semicircle fixedmount 1 inwall is provided withring tooth 9, andslide block 5 is provided with the knuckle-tooth 8 that matches withring tooth 9.

Locatinghole 10 is greater thandowel hole 13, andslide block 5 can be in cavity 11 slide inside, and the locating hole above theslide block 5 is oblong.

During work, whenpull bar 4 is raised, pullbar 4drives contractibilities 3 upwards mentions, and theslide block 5 of inclination shrinks under the pressure ofspring 7 inwards, knuckle-tooth 8 on theslide block 5 breaks away from thering tooth 9 on 1, thereby pullbar 4,main body 2, spring 6,slide block 5,contractibility 3 can integral body move up and down.Alignment pin 7 passes 2dowel holes 13 of bottom above thepull bar 2,2 locatingholes 10 that pass above theslide block 5 are located respectively 2 slide blocks 5.When releasinglever 4,slide block 5 advances downwards under the thrust of spring 6, causesslide block 5 to the both sides expansion, and the round tooth above theslide block 5 andring tooth 9 interlocks above the semicircle fixedmount 1 reach fixation.

The accurate positioning of the utility model lifting locking device, easy to adjust, generally be installed in the pillar of computer desk, be useful in equally in computer desk, desk, the study table.
