DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] As attached Figure 1 , 2 As shown in Figures , 3, 4, 5 and 6, the utility model provides a sofa support leg, including a mounting seat 1 and a support column 2, the support column 2 is arranged at the lower part of the mounting seat 1, the support column 2 and the mounting seat 1 are an integrally formed structure, the outer surface of the support column 2 is sleeved with a protective cover 3, the lower part of the support column 2 is arranged with a support seat 4, the interior of the support seat 4 is arranged with a screw 5, one end of the screw 5 is fixed to the side of the support seat 4 facing the support column 2, the other end of the screw 5 is movably arranged at one end of the support column 2, and a plurality of mounting holes 11 are subsequently arranged on the upper surface of the mounting seat 1, and the mounting holes 11 pass through the mounting seat 1.

[0022] When installing the sofa support leg: align the mounting hole 11 on the mounting base 1 with the positioning hole on the bottom surface of the sofa, and then set a fastening screw at the mounting hole 11, so that the mounting base 1 can be directly installed on the bottom surface of the sofa, because the support column 2 and the mounting base 1 are an integrally formed structure, when the mounting base 1 is installed on the bottom surface of the sofa, it can be installed on the bottom surface of the sofa together with the support column 2, and then the support base 4 is movably connected to the support column 2 through the screw rod 5, so that only two steps are needed to quickly realize the rapid assembly and installation operation of the sofa support leg, which will reduce the difficulty of installing the sofa leg and reduce the installation time of the sofa leg to the bottom surface of the sofa, thereby improving the assembly efficiency.

[0023] Subsequently, a through hole 21 is opened inside the support column 2, one end of the through hole 21 passes through the support seat 4, and a nut member 6 is arranged inside the end of the through hole 21 facing the support seat 4, and the nut member 6 is threadedly connected with the screw rod 5, so that the support seat 4 can be displaced through the threaded connection between the nut member 6 and the screw rod 5, thereby enabling the support seat 4 to move up and down through the threaded connection between the nut member 6 and the screw rod 5.

[0024] When the height of the sofa needs to be adjusted, the sofa support legs are first installed at the four corners of the bottom surface of the sofa, and then the bottom surface of the support seat 4 is lifted off the ground by lifting the sofa, and then the support seat 4 is rotated, and the nut 6 is threadedly connected with the screw 5. When the support seat 4 is rotated counterclockwise, the support seat 4 can be moved away from the support column 2, thereby increasing the overall length of the sofa support legs, so that the bottom surface of the sofa can be lifted further away from the ground, thereby achieving the lifting of the sofa;

[0025] On the contrary, it is known that when the support seat 4 is rotated clockwise, the support seat 4 can be brought close to the support column 2, thereby reducing the overall length of the sofa support legs, thereby lifting the bottom surface of the sofa closer to the ground, thereby achieving the lowering operation of the sofa.

[0026] As attached Figure 3 , 4 As shown in FIG. 5 , a positioning groove 7 is provided at the connection between the mounting seat 1 and the support column 2, and one end of the protective cover 3 is arranged in the positioning groove 7, so that the protective cover 3 can be quickly positioned;

[0027] Subsequently, a locking boss 8 is provided at one end of the support column 2 away from the mounting seat 1, and a clamping portion 31 is provided at the other end of the protective cover 3. The clamping portion 31 is clamped to the locking boss 8. The installation of the protective cover 3 can be facilitated by the clamping method, thereby improving the installation efficiency of the overall structure of the sofa support leg.

[0028] Preferably, the protective cover 3 is made of stainless steel.

By providing the anti-slip strips 9 and the anti-slip grooves 10, the support base 4 will not slip when in contact with the ground, thereby ensuring the normal use of the sofa.

[0030] Preferably, the mounting base 1, the support column 2 and the support base 4 are made of hard plastic, because the connecting parts between the conventional support legs and the bottom of the sofa are basically made of metal. When the sofa support legs are used for a long time, the connecting parts with the bottom of the sofa will oxidize and rust. By using hard plastic for the mounting base 1, the support column 2 and the support base 4, the problem of the normal use of the sofa support legs being affected by oxidation and rust of the connecting parts can be reduced, the service life of the sofa support legs can be improved, and the damage to the bottom of the sofa can also be reduced.
