Detailed description of the invention

This utility model is further illustrated by explanation and detailed description of the invention below in conjunction with the accompanying drawings.

As it is shown in figure 1, a kind of extension adjustment device 1, including bar 13, spring the 14, first rivet nut 15 and the second rivet nut 16 in bar 12, second in outer tube 11, first, in first, the relative outer tube 11 of bar 12 can stretch, and in second, the relative outer tube 11 of bar 13 also can stretch.The middle part of outer tube 11 has the first slotted eye and the second slotted eye；In first, in bar 12, spring 14, second, bar 13 order abuts and is inserted in outer tube 11；First rivet nut 15 is through bar 12 in the first slotted eye embedding first；Second rivet nut 16 is through bar 13 in the second slotted eye embedding second；First rivet nut 15 moves towards spring 14 along the first slotted eye with bar 12 in first can extrusion spring 14, it is achieved the inside contracting of bar 12 in first, and spring 14 resets bar 12 in promoting first, it is achieved in first, bar 12 is overhanging.Second rivet nut 16 moves towards spring 14 along the second slotted eye with bar 13 in second can extrusion spring 14, it is achieved the inside contracting of bar 13 in second, and spring 14 resets bar 12 in promoting first, it is achieved in second, bar 13 is overhanging.One hand holds the first rivet nut 15 and the second rivet nut 16, and holds with a firm grip, i.e. realizes in first inside contracting of bar 13 in bar 12 and second, i.e. realizes in first the overhanging of bar 13 in bar 12 and second after loosing one's grip, easy to operate.

In this utility model first, in bar 12, second, bar 13 matches with outer tube 11, and is inserted in outer tube 11.Such as, in first, in bar 12 and second, bar 13 is square tube, and outer tube 11 is also square tube, and in first, in bar 12, second, bar 13 matches to merge with outer tube 11 and is arranged in outer tube 11.Or, this extension adjustment device 1 includes multiple spacer 17；The plurality of spacer 17 be embedded at first respectively in bar 13 in bar 12 and second；Having in the first of multiple spacer 17 bar 13 in bar 12, second and coordinate and be inserted in outer tube 11, use spacer 17, in first, in bar 12 and second, bar 13 can use less radial dimension, saves material.

It is open configuration that this utility model the first rivet nut 15 embeds one end of bar 12 in first；It is also open configuration that second rivet nut 16 embeds one end of bar 13 in second.Owing to its built-in end is open configuration, this open configuration can for all to open, such as one-to-two, one point three, more than one point, it is also possible to open for part, such as the outer volume of side material.This open configuration ensure that the fastness of first rivet nut the 15, second rivet nut 16, does not falls off.

Generally, this first rivet nut 15 and the second rivet nut 16 are each perpendicular to outer tube 11, it is also possible to use the embedded mode of inclination.

In first, bar 12 has the thin axle protruding from outer tube 11；In second, bar 13 also has the thin axle protruding from outer tube 11.

As depicted in figs. 1 and 2, a kind of feet 2, including foot rest 24 in 23, the second outer foot rest 22 and second of foot rest in the first outer foot rest 21, first；In first outer foot rest 21 and first, foot rest 23 cooperates, and in the second outer foot rest 22 and second, foot rest 24 cooperates；First outer foot rest 21 and the second outer foot rest 22 correspondence position are respectively provided with an altitude hole, and in first, in foot rest 23 and second, foot rest 24 correspondence position is respectively provided with many altitude holes, also included extension adjustment device 1；The altitude hole of foot rest 23 in the free end of bar 12 coordinates insertion the first outer foot rest 21, first in first；The altitude hole of foot rest 24 in the free end of bar 13 coordinates insertion the second outer foot rest 22, second in second.When one hand is caught the first rivet nut 15 and the second rivet nut 16 and exerts a force, in first, in bar 12, second, bar 13 inside contracts, the altitude hole of foot rest in departing from, and so interior foot rest i.e. can move relative to outer foot rest, it is achieved altitude mixture control.Feet 2 of the present utility model, in order to ensure that it is in a certain height, pre-anti-misoperation, safety buckle 25 is set, this safety buckle 25 has two hooks, catches on the first rivet nut 15 and the second rivet nut 16 respectively, in order to avoid first rivet nut the 15, second rivet nut 16 is hit the shakiness causing feet 2 by mistake.For the ease of the use of safety buckle 25, a blind rivet 26 is set, this blind rivet 26 attachment security button 25, i.e. safety buckle 25 can be pulled out.

As shown in Figure 1 to Figure 3, a kind of desk 3, including desktop 31, table framework 32, feet 2, table framework 32 carries desktop 31, and feet 2 is connected with table framework 32；Aforesaid feet 2 is at least two.Also including foldable assembly 33, one end of foldable assembly 33 connects table framework 32, the other end connects feet 2, facilitates feet 2 to pack up.

This utility model one hand is held with a firm grip after catching first rivet nut the 15, second rivet nut 16, and spring 14 is extruded, and drives in first in bar 12, second bar 13 to inside contracting simultaneously；After loosing one's grip, under the active force of spring 14, in first, in bar 12 and second, bar 13 resets, it is achieved overhanging.This extension adjustment device 1 coordinates outer foot rest, interior foot rest, it is possible to be used for regulating the height of feet 2, and then the height of regulation desk 3.Based on this structure, it is achieved while furniture height regulation, it is ensured that the convenience of operation.

Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
