[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range protected by the utility model.
[0024] As Figs. 1 to 4 Shown, a kind of extrusion spring buckle connection telescopic structural member, including main telescopic pipe 1, the opposite two sides of main telescopic pipe 1 middle are all set up press hole 2, compression spring 3 is installed in main telescopic pipe 1, the opposite sides of compression spring 3 are all fixedly connected with main pressure block 4 that adaptation press hole 2, press button 5 is installed on the outside of main pressure block 4, vice telescopic pipe 6 is sleeved on one side of main telescopic pipe 1, three limit holes 7 are evenly arranged on the two sides of vice telescopic pipe 6, pass column hole 8 is set on the side of main telescopic pipe 1 away from press hole 2, clamping column 9 is fixedly connected on the two sides of compression spring 3, and the distance between main telescopic pipe 1 and vice telescopic pipe 6 is adjusted by synchronously pressing two press buttons 5;
[0025] It needs to be explained that, when main telescopic pipe 1 is used, the outside is integrated with the leg of table and chair to be adjusted, and compression spring 3 is preferably double-layer Z-shaped extrusion spring, which has deformation capacity and strong structural strength, to avoid easy deformation caused by accidental touch, thereby improving the anti-interference capability of structural member when used.
[0026] The outer diameter of one side of main telescopic pipe 1 close to vice telescopic pipe 6 is less than the outer diameter of the side close to press hole 2, and the inside of vice telescopic pipe 6 is attached to the outside of adjacent main telescopic pipe 1.
[0027] The main pressing block 4 comprises a side frame 41 fixedly connected with the side of the compression spring 3, and a pressing plate 42 fixedly connected with the outer side of the side frame 41, wherein the vertical cross section of the pressing plate 42 is square, and the inner side of the pressing hole 2 is shaped to match the shape of the side surface of the pressing plate 42;
[0028] The extension direction of the compression spring 3 is parallel to the direction of the line connecting the center points of the two pressing holes 2, and the center points of each pressing hole 2, the limiting hole 7 and the through-hole 8 are located on the same horizontal plane;
[0029] It should be noted that the outer diameter of the main telescopic pipe 1 near the side of the auxiliary telescopic pipe 6 is smaller, so that when the auxiliary telescopic pipe 6 adjusts the height with the main telescopic pipe 1, the minimum distance between the auxiliary telescopic pipe 6 and the main telescopic pipe 1 can be limited by the abutting of the main telescopic pipe 1 and the auxiliary telescopic pipe 6, and preferably, when the clamping column 9 is slidingly connected with the innermost limiting hole 7, the side of the main telescopic pipe 1 with the larger outer diameter is in contact with the adjacent side of the auxiliary telescopic pipe 6, thereby achieving the limiting function of height adjustment;
[0030] Since the compression direction of the compression spring 3 is parallel to the direction of the line connecting the center points of the two pressing holes 2, and the center points of each pressing hole 2, the limiting hole 7 and the through-hole 8 are located on the same horizontal plane, when the two sides of the compression spring 3 are pressed, the clamping column 9 connected with the compression spring 3 moves in the same direction as the pressing button 5 on the same side, thereby realizing the simultaneous extension and contraction control of the clamping column 9 and the pressing button 5;
[0031] In addition, since the compression spring 3 is limited between the main telescopic pipe 1 and the auxiliary telescopic pipe 6 by the two pressing plates 42 and the two clamping columns 9 in the static state, and the extension and contraction states of the two clamping columns 9 can be synchronously controlled by pressing the pressing button 5, when the pressing button 5 is pressed, it is necessary to avoid the occurrence of lateral rotation force of the compression spring 3 along the line connecting the center points of the two pressing holes 2 as the axis, thereby improving the difficulty of pressing, so that the pressing hole 2 is designed as a slot, which can effectively avoid the occurrence of lateral torsion force and the possibility of rotation of the compression spring 3, thereby improving the convenience of pressing the compression spring 3, and effectively avoiding the problem of deviation of the abutment of the limiting hole 7 and the clamping column 9 caused by the rotation of the compression spring 3;
[0032] Furthermore, since the clamping columns 9 on both sides of the compression spring 3 need to be retracted to adjust the height by synchronously pressing the pressing button 5, when a user mistakenly presses a single pressing button 5, height adjustment error will not occur, thereby improving the stability of the height adjustment structure and effectively avoiding the occurrence of mistaken adjustment.
[0033] The clamping column 9 comprises a side plate 91 fixedly connected with the compression spring 3, and a side rod 92 fixedly connected with the outer side of the side plate 91;
[0034] The diameter of the through-hole 8 is larger than the diameter of the limiting hole 7, the side rod 92 is slidingly connected with the adjacent limiting hole 7, and the outer diameter of the side rod 92 is matched with the diameter of the limiting hole 7;
[0035] It should be noted that the through column hole 8 is arranged on one side of the thinner end of the main telescopic pipe 1, and is sleeved on the inner side of the auxiliary telescopic pipe 6, so that the card column 9 cannot be interfered by the through column hole 8 during the process of being retracted and then stretched out, and therefore the aperture of the through column hole 8 is larger; in addition, the outer diameter of the side rod 92 is matched with the aperture of the limiting hole 7, and the purpose is to maintain the stability of the relative distance between the main telescopic pipe 1 and the auxiliary telescopic pipe 6 after height adjustment, so as to improve the stability of the table and chair support during the height adjustment process.
[0036] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the implementation range of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage range of the present application.
