[0017] The technical scheme in the utility model is further explained below in combination with the drawings and embodiments.

[0018] Embodiment:

[0019] As Figure 1 And Figure 2As shown, a chair leg plug 2, comprising a plug 2 for mounting at the end of a chair leg 1, the chair leg 1 is a hollow structure and the end is open, and the chair leg 1 is made of metal, the plug 2 is inserted into the inside of the chair leg 1 through the end of the chair leg 1, the plug 2 is provided with a mounting hole 3, the side wall of the chair leg 1 is provided with a threaded hole 10, the mounting hole 3 corresponds to the threaded hole 10; It also includes a support foot, the support foot includes a mounting rod 4 and a support base 5 fixedly connected with the mounting rod 4, the mounting rod 4 is a threaded rod, the threaded structure of the mounting rod 4 is matched with the threaded structure in the threaded hole 10, and the end of the mounting rod 4 away from the support base 5 is used to be screwed into the threaded hole 10, then through the mounting hole 3, it is inserted into the inside of the chair leg 1.

[0020] By setting the mounting hole 3, the threaded hole 10 and the mounting rod 4, the plug 2 is first inserted into the chair leg 1 by using friction, then the mounting rod 4 is used to be screwed into the threaded hole 10 through the mounting hole 3 and the threaded hole 10, and the mounting rod 4 is screwed into the threaded hole 10, so that the position of the plug 2 is limited by inserting the mounting rod 4 into the mounting hole 3, preventing the plug 2 from moving out of the chair leg 1, thereby achieving the fixation of the plug 2;

[0021] By setting the support base 5, not only can it save labor when rotating the mounting rod 4, but also because the support base 5 is in contact with the ground, the direct contact between the chair leg 1 and the ground is reduced, thereby reducing the noise generated when moving the chair, and at the same time, the wear and tear of the chair leg 1 on the floor is reduced, the service life of the floor is prolonged, and scratches or depressions caused by long-term friction are avoided.

[0022] As shown in Figures 1 to 4 , the plug 2 includes an insertion section 201 and an exposed section 202, the insertion section 201 is used to be inserted into the inside of the chair leg 1, and the mounting hole 3 is arranged on the insertion section 201, and the exposed section 202 is in abutment with the end surface of the chair leg 1. The outer surface of the insertion section 201 is in contact with the inner surface of the chair leg 1, so the friction between the outer surface of the insertion section 201 and the inner surface of the chair leg 1 preliminarily installs the plug 2 in the chair leg 1, and the abutment of the exposed section 202 with the end surface of the chair leg 1 makes the exposed section 202 unable to further penetrate into the inside of the chair leg 1, so it can be exposed outside the chair leg 1, thereby protecting the end of the chair leg 1, preventing the user's feet from kicking the hard metal chair leg 1 and causing strong pain, and in severe cases, it can also cause foot bleeding and other conditions.

[0023] As shown in Figure 1 , Figure 2 , and Figure 3 , the surface of the exposed section 202 is an arc surface. The arrangement of the arc surface can avoid the risk of knocking caused by the sharp edges of the end of the chair leg 1, reduce the risk of injury, and at the same time, increase the artistic sense of space and improve the overall quality of the chair. As shown in Figure 1 , andFigure 2 As shown in the drawings, the outer surface of the support base 5 is provided with several grooves 6 evenly distributed along the axial direction of the support base 5. The main purpose of providing the grooves 6 is to increase the friction of the support base 5, prevent the fingers from slipping when rotating the mounting rod 4 through the support base 5, and improve the safety of use.

[0024] As shown in the drawings, Figure 3 and 4 The plug-in section 201 includes a mounting plate 8 and two hollow mounting blocks 9, the mounting plate 8 is fixed between the two mounting blocks 9, the mounting hole 3 is arranged on the mounting plate 8, and the two mounting blocks 9 are provided with openings near one side of the support base 5. The hollow structure and the opening can reduce the total weight of the plug 2, thereby reducing the total weight of the chair leg 1, making the chair more lightweight; secondly, the hollow structure can improve the strength and bending resistance of the plug 2, preventing deformation of the end of the chair leg 1.

[0025] As shown in the drawings, Figure 3 The exposed section 202 is a hollow structure, and one side of the exposed section 202 is provided with an opening, the side of the exposed section 202 opening is consistent with the side of the two mounting blocks 9 opening, and the exposed section 202 hollow structure is provided with a support strip 7. The support strip 7 can enhance the overall stiffness and stability of the hollow structure of the plug 2, preventing deformation and damage of the plug 2 under lateral load.

[0026] Working principle:

[0027] During installation, the plug-in section 201 of the plug 2 is inserted into the end of the chair leg 1, then the support base 5 is held and rotated to screw the mounting rod 4 into the threaded hole 10, the mounting rod 4 passes through the mounting hole 3 and extends into the inside of the chair leg 1, at this time the mounting rod 4 fixes the plug 2 in the inside of the chair leg 1, finally the support base 5 contacts with the ground, and the whole operation is completed.

[0028] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
