[0002] The leg component generally refers to a telescopic support leg component, which is generally composed of a plurality of rod bodies sleeved inside a rod. During use, the rod bodies inside the leg component need to be extended outward to complete the support of the leg component. And the leg component is generally made of metal or hard plastic materials to ensure the compressive strength of the leg component itself.
[0003] In order to facilitate rapid expansion of the existing leg component, during the telescoping process of its internal rod, a spring is generally used to push a curved surface structure for support, so as to facilitate rapid extension. And during the contraction process, the rod needs to be directly extruded, so that the curved surface structure retracts and squeezes the spring to complete the contraction process of the leg component.
[0004] The above-mentioned leg component still has certain use defects during use. The curved surface structure will be worn during long-term use, affecting the support effect of the curved surface structure. And during the support process of the leg component, the curved surface structure is likely not to be telescoped in place, easily leading to the retraction of the leg component during use, affecting the support stability of the leg component.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0026] In a specific embodiment, as Figure 1 - Figure 2 shown, the basic working process of the leg assembly is disclosed;
[0027] The first rod 1 and the mounting sleeve 2 fixedly installed on the outside of the first rod 1;
[0028] A second rod 3 is slidably installed inside the first rod 1, and a third rod 4 is slidably installed inside the second rod 3.
[0029] When using the telescopic leg assembly, it is necessary to install the leg assembly during work and expand the leg assembly. During the expansion process, it is necessary to make the second rod 3 and the third rod 4 move outward from the inside of the first rod 1 and support. During this process, it is necessary to first make the third rod 4 slide outward inside the second rod 3, and then make the second rod 3 slide outward inside the first rod 1. At this time, the second rod 3 and the third rod 4 can be limited, so as to ensure the stability of the expansion of the leg assembly.
[0030] In one specific embodiment, as Figure 1 - Figure 4 shown, the expansion process of the leg assembly is disclosed;
[0031] A mounting hole 5 is opened inside the third rod 4, and a mounting rod 6 and a limiting rod 7 are slidably installed inside the mounting hole 5. The mounting rod 6 is slidably connected to the limiting rod 7, and a nut 8 is threadedly installed on the outside of the end of the limiting rod 7 away from the mounting rod 6. At the same time, the nut 8 is located outside the third rod 4;
[0032] When using the telescopic leg assembly, it is necessary to remove the docking part 16 from the engaging hole 17 inside the first rod 1 and the docking hole 13 inside the third rod 4. After that, the mounting rod 6 and the limiting rod 7 inside the splicing hole 15 can be removed. At this time, the third rod 4 can slide outwards inside the second rod 3, and at this time, the arc-shaped clamping part 11 will separate from the clamping groove 12 and the U-shaped spring 10 will be squeezed. After the U-shaped spring 10 is squeezed, it will contract. After the arc-shaped clamping part 11 separates from the clamping groove 12, the mounting rod 6 and the limiting rod 7 can be installed inside the mounting hole 5, and the nut 8 needs to be installed outside the limiting rod 7. After that, the second rod 3 can slide outwards inside the first rod 1, and the second rod 3 drives the third rod 4 to slide synchronously, so as to complete the expansion process of the leg assembly.
[0033] On the basis of the above embodiments, as Figure 1 - Figure 6 shown, the problem that it is difficult to stably support the existing leg assembly after expansion is solved;
[0034] A fixing block 9 is fixedly installed inside the third rod 4, and a U-shaped spring 10 is clamped and installed at the lower end of the fixing block 9, and an arc-shaped clamping part 11 is clamped and installed at one end of the U-shaped spring 10 away from the fixing block 9;
[0035] The arc-shaped clamping part 11 is slidably connected to the third rod 4, a clamping groove 12 is opened inside the second rod 3, the arc-shaped clamping part 11 is clamped and connected to the clamping groove 12, and a docking hole 13 is opened inside the third rod 4;
[0036] A splicing hole 15 and an engaging hole 17 are opened inside the first rod 1, a connecting hole 14 is opened inside the second rod 3, and a docking part 16 is clamped and installed inside the connecting hole 14 and the engaging hole 17;
[0037] There are two groups of docking parts 16 inside the first rod 1, and magnetic blocks 18 are fixedly installed at the ends of the docking parts 16 close to each other, and the two magnetic blocks 18 attract each other.
[0038] After the second rod 3 and the third rod 4 are expanded, the docking part 16 can be reinstalled inside the engaging hole 17 and the docking part 16 can penetrate through the connecting hole 14. At this time, the magnetic blocks 18 outside the docking part 16 will attract each other and limit the second rod 3 inside the first rod 1, so as to ensure the stability of the support between the second rod 3 and the first rod 1; effectively improving the convenience and stability of the use of the leg assembly, and increasing the overall practicality.
[0039] The content not detailed in this specification belongs to the prior art well known to those skilled in the art.
[0040] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
