Abstract
The utility model relates to a retractable desk leg. The desk leg comprises a hollow desk leg. A scale is arranged on the right side face of the hollow desk leg, and a strip-shaped groove is formed in the rear side face of the hollow desk leg. A pneumatic supporting pipe and a supporting desk leg are arranged in the hollow desk leg in a sleeved mode, wherein the pneumatic supporting pipe and the supporting desk leg are connected. A fixing screw is arranged in the strip-shaped groove and connected with the supporting desk leg. The retractable desk leg has the advantages of being simple in structure, low in manufacturing cost, convenient to adjust rapidly due to auxiliary adjustment of the pneumatic supporting pipe and capable of being adjusted in a stepless mode, and the adjusted height can be intuitively observed.
Description
Technical field
The utility model relates to a kind of scalable table leg.
Background technology
School desk all is unified making and is equipped with, but each grade and single student's height all is discrepant, tired out easily when use is not suitable for the desk of own height, the myopia even bow-backed of student.In the occasion of some ground reliefs, a kind of desk that has scalable table leg all is very necessary in addition.The disclosed a kind of scalable desk of granted patent CN 202233899 U, though scalable, can not step-less adjustment, can only be in limited several numerical value adjusted, this is on broken terrain and impracticable.The disclosed a kind of scalable table leg of Granted publication CN 2909946 Y in addition, the structure relative complex, complicated structure means rising and the raising of probability of damage and the more frequent maintenance of manufacturing cost.Above-mentioned disclosed two kinds of scalable table legs all do not design scale, can not observe the numerical value that needs adjusting intuitively, and each table leg all needs to be adjusted to repeatedly suitable height during adjusting.In addition in actual applications, because existing scalable table leg employing all is that cover supports table leg in the hollow table leg, both cooperations are tight slightly just the situation of stuck difficult adjusting to take place easily, regulates inconvenience relatively, does not have to design the flexible automatically device of auxiliary table leg.
The utility model content
The purpose of this utility model provides a kind of scalable table leg, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of scalable table leg, comprise hollow table leg, described hollow table leg right flank is provided with scale, and described hollow table leg trailing flank is provided with strip groove, be with continuous pneumatic stay pipe in the described hollow table leg and support table leg, be provided with in the described strip groove and support the hold-down screw that table leg is connected.
Further, described support table leg is provided with holddown groove.
The beneficial effects of the utility model are: a kind of scalable table leg that the utility model provides, simple in structure, low cost of manufacture adopts pneumatic stay pipe auxiliary adjustment, and is easy to adjust quick, can realize step-less adjustment and can intuitively observe the adjusting height.

Among the figure:
1, hollow table leg; 2, scale; 3, strip groove; 4, support table leg; 5, hold-down screw; 6, holddown groove; 7, pneumatic stay pipe.
The specific embodiment
Shown in Fig. 1-8, the described a kind of scalable table leg of the utility model embodiment, comprise hollow table leg 1, described hollow table leg 1 right flank is provided with scale 2, described hollow table leg 1 trailing flank is provided with strip groove 3, be with continuous pneumatic stay pipe 7 in the described hollow table leg 1 and support table leg 4, be provided with in the described strip groove 3 and support the hold-down screw 5 that table leg 4 is connected.Described support table leg 4 is provided with holddown groove 6.
During making, two kinds of preparation methods can be arranged, the one, on hollow table leg 1, make strip groove 3, support table leg 4 and make screw hole cooperation hold-down screw 5; The 2nd, supporting making holddown groove 6 on the table leg 4, make screw hole on the hollow table leg 1 and cooperate hold-down screw 5; Pneumatic stay pipe 7 adopts tables and chairs industry air pressure rod commonly used, does not give unnecessary details at this.
During use, unclamp hold-down screw 5, pneumatic stay pipe 7 will support table leg 4 automatically and eject, and not need the manpower hard draw to drag by force, and laborsaving saving time arrives when needing length, and the screw 5 that is tightened is remembered the scale of scale 2, regulates the residue table leg according to scale, and is fast convenient.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but on its shape or structure, do any variation; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
