Computer desk
Technical field
The present invention relates to computer corollary equipment field, particularly relate to a kind of computer desk.
Background technology
At present, common computer desk be all by four only collapsible can not rotation with the leg of unadjustable height support.This is for common operating personnel, so because the leg of computer desk is not rotatable and unadjustable height computer desk can only keep a form.Therefore operating personnel also just can not also be difficult to realize in narrow space according to the height of s own situation adjustable computer desk the variation of sitting posture simultaneously.Afterwards as the patent Shen file of Chinese application number 201120003366.6 discloses a kind of computer desk, computer desk main body is supported by four legs that rotate around its rotating shaft, every leg is made up of two joints, by regulating the height that supporting leg can adjustable computer desk, also can realize the folding of computer desk.But this folding supporting leg is insecure, easily shake.
In sum, for the defect of prior art, need especially a kind of computer desk, thereby solve above-mentioned problem.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of computer desk, can solve traditional computer desk, and folding supporting leg is insecure, easily the problem of shake.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of computer desk is provided, comprise desktop, the below of described desktop is provided with table pin that can free-extension, described table pin comprises the first support bar and the second support bar, and the upper end of described the first support bar is fixedly connected with desktop, and intert in the second support bar the lower end of the first support bar, on described the first support bar and the second support bar, be arranged with through hole, in through hole, be provided with the support bar for regulating.
In a preferred embodiment of the present invention, the below of described the second support bar is provided with the base plate for increasing lifting surface area.
In a preferred embodiment of the present invention, the upper end of described the first support bar is fixedly connected with by the mode of welding with desktop.
The invention has the beneficial effects as follows: the present invention is simple in structure, design ingenious, in use, only need in through hole, extract support bar out, then pass through the upper and lower of desktop, thereby change the through hole on the first support bar, position with through hole on the second support bar, in the time that the through hole on two support bars is overlapping, then support bar is inserted in through hole, thereby reach the object of adjusting; Below the second support bar, weld base plate, increased like this lifting surface area, be difficult for rocking thereby use computer desk.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of computer desk of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of computer desk of the present invention, comprise desktop 1, the below of described desktop 1 is provided with table pin that can free-extension, described table pin comprises the first support bar 2 and the second support bar 3, and the upper end of described the first support bar 2 is fixedly connected with desktop, and intert in the second support bar 3 lower end of the first support bar 2, on described the first support bar 2 and the second support bar 3, be arranged with through hole, in through hole, be provided with the support bar 5 for regulating.
In addition more firm in order to use, the upper end that the below that is difficult for rocking the second support bar 3 is provided with base plate 6, the first support bars 2 for increasing lifting surface area is fixedly connected with by the mode of welding with desktop 1.
The present invention is simple in structure, design ingenious, in use, only need in through hole, extract support bar out, then pass through the upper and lower of desktop, thereby change the through hole on the first support bar, position with through hole on the second support bar, in the time that the through hole on two support bars is overlapping, then support bar is inserted in through hole, thereby reach the object of adjusting; Below the second support bar, weld base plate, increased like this lifting surface area, be difficult for rocking thereby use computer desk.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
