Abstract
The utility model relates to the technical field of computer tables, in particular to a computer table column lifting locker. The computer table column lifting locker comprises two semi-circular fixing frames, a main body, a contracting part, a pull rod, a sliding block, a spring and a positioning pin. The bottom of the pull rod is connected with the contracting part, the two semi-circular fixing frames respectively surround two ends of the main body to form a cylinder, and the contracting part, the pull rod, the sliding block, the spring and the positioning pin are located in the cylinder. The pull rod penetrates through a positioning pin hole at the bottom of the main body and a positioning hole on the sliding block to fix the sliding block in a cavity. An outer wall of the bottom end of the main body is provided with a circle of annular groove, a lower half section of the sliding block is provided with a groove connected with the annular groove, inner walls of the semi-circular fixing frames are provided with annular teeth, and the sliding block is provided with round teeth matched with the annular teeth. The positioning hole is larger than the positioning pin hole. The computer table column lifting locker is simple in structure and convenient to use and can be installed in a table column of a learning table, an office table, the computer table or others to adjust and lock the height of the table.
Description
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 fixed mounts 1, main body 2, contractibility 3, pull bar 4, slide block 5, spring 6 and alignment pin 7, pull bar 3 bottoms connect contractibility 4, two semicircle fixed mounts 1 are enclosed in respectively main 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 passes main body 2 and spring 6 connects contractibility 3, the latter half of main body 2 is provided with a cavity 11, alignment pin 7 passes the dowel hole 13 of main body 2 bottoms, and the locating hole 10 on the slide 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, and slide block 5 lower semisections are provided with the groove 14 of accepting mutually with annular groove 12, and semicircle fixed mount 1 inwall is provided with ring tooth 9, and slide block 5 is provided with the knuckle-tooth 8 that matches with ring tooth 9.
Locating hole 10 is greater than dowel hole 13, and slide block 5 can be in cavity 11 slide inside, and the locating hole above the slide block 5 is oblong.
During work, when pull bar 4 is raised, pull bar 4 drives contractibilities 3 upwards mentions, and the slide block 5 of inclination shrinks under the pressure of spring 7 inwards, knuckle-tooth 8 on the slide block 5 breaks away from the ring tooth 9 on 1, thereby pull bar 4, main body 2, spring 6, slide block 5, contractibility 3 can integral body move up and down.Alignment pin 7 passes 2 dowel holes 13 of bottom above the pull bar 2,2 locating holes 10 that pass above the slide block 5 are located respectively 2 slide blocks 5.When releasing lever 4, slide block 5 advances downwards under the thrust of spring 6, causes slide block 5 to the both sides expansion, and the round tooth above the slide block 5 and ring tooth 9 interlocks above the semicircle fixed mount 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.
