Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The first embodiment is as follows: as shown in fig. 1-5, which is only one embodiment of the present invention, a detachable five-star chair leg includes a central body 10 and five support legs 20 disposed around the central body 10, wherein one end of the central body 10 is provided with a mounting groove 13, an end wall 14 of the mounting groove 13 in the extending direction of the central body 10 is provided with a mounting hole 141, and the end of each support leg 20 is sequentially connected with a plug 21 and a stopper 24;

the plug 21 is a wedge shape with the height gradually decreasing along the direction pointing to the stopper 24, so that the plug 21 can be lifted along the direction away from the bottom wall of the mounting groove 13 in the process of being inserted into the mounting groove 13, and the stopper 24 can stop the plug 21 not departing from the mounting groove 13 by extending out of the mounting hole 141; or so that the plug 21 drops to the stopping position of the stopping head 24 always maintained in the state that the bottom wall of the mounting groove 13 is placed upwards.

Wherein, the central body 10 comprises a base 11 and an extension 12 extending from the base 11, and one end of the extension 12 is provided with a mounting groove 13. The plug 21 includes a first connection portion 211 and a second connection portion 212, the first connection portion 211 is provided with a connection block 22 passing through the mounting hole 141, and the connection block 22 is provided with a stopper 24.

The end walls 14 at both sides of the mounting groove 13 are provided with guide grooves 131, and the second connecting portion 212 is provided with guide blocks 213 which slide in cooperation with the guide grooves 131. The guide block 213 may have a rectangular parallelepiped shape, a cylindrical shape, or the like, and the guide block 213 is preferably cylindrical in shape in order to stably and smoothly slide the guide block 213 in the slide groove. The connecting block 22 is provided with a necking groove 23 for inserting the hole wall of the mounting hole 141, and the necking groove 23 is rectangular.

When the supporting foot 20 is installed, the guide block 213 of the supporting foot 20 is inserted into the sliding slot, and the supporting foot 20 is pushed into the installation slot 13, because the plug 21 is wedge-shaped, the height thereof is gradually reduced along the direction pointing to the stopper 24, the stopper 24 can obliquely pass through the installation hole 141, and then the supporting foot 20 is pressed to the horizontal, so that the hole wall of the installation hole 141 is inserted into the lock catch slot. It should be noted that the stopping head 24 and the end wall 14 of the mounting groove 13 stop each other to limit the horizontal relative displacement of the supporting leg 20, the connecting block 22 and the hole wall of the mounting hole 141 stop each other to limit the vertical displacement of the supporting leg 20, and the guide block 213 and the sliding groove are cooperatively mounted to further limit the vertical displacement of the supporting leg 20.

After the supporting leg 20 is installed, referring to fig. 5, the five-star chair leg is connected to the chair leg through the central hole 16 and supported on the ground, and at this time, the bottom wall of the installation groove 13 is located above the installation groove 13, that is, when the bottom wall of the installation groove 13 is in an upward-placed state, the plug-in connector 21 is supported on the ground due to gravity and always maintains the stopping position of the stopping head 24. Since the five-star chair leg is made of plastic, the stopper 24 has elasticity that enables the stopper 24 to turn over relative to the plug 21.

The upper side of the supporting foot 20 is provided with a non-slip mat 30, and the non-slip mat 30 is provided with non-slip lines 31.

The central body 10 is provided on the underside with a first support 15 and the foot 20 is provided on the underside at one end with a second support 25.
