Specific embodiments

[0026] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0027] Embodiment:

[0028] Referring to Figures 1 to 4 , this application is a segmented detachable chair leg, including a fixed sleeve 1 for connecting with a seat. A through hole 11 with a large top opening and a small bottom opening is provided on the fixed sleeve 1. A plurality of connecting rods 2 are uniformly fixed on the outer side wall of the fixed sleeve 1. One end of each of the plurality of connecting rods 2 away from the fixed sleeve 1 is detachably provided with a support leg 3. A connecting groove 12 for connecting a roller is provided at the bottom of one end of each of the plurality of support legs 3 away from the connecting rod 2. Mounting grooves 4 are provided at the ends of the plurality of connecting rods 2 away from the fixed sleeve 1. The ends of the plurality of support legs 3 are threadedly inserted into the corresponding mounting grooves 4 one by one. A reinforcing member is provided at the connection between each of the plurality of support legs 3 and the corresponding plurality of connecting rods 2. The reinforcing member includes a reinforcing rod 6. The reinforcing rod 6 is threadedly inserted into the support leg 3 along the axial direction of the support leg 3. One end of the reinforcing rod 6 extends into the mounting groove 4 and is threadedly connected to the corresponding connecting rod 2. A slotted hole 10 is provided at the end of the reinforcing rod 6 away from the connecting rod 2, and the reinforcing rod 6 is divided into a threaded section 13 and a smooth rod section 14, which can facilitate personnel to quickly install by holding the smooth rod section 14 during use.

[0029] As Figure 2 and Figure 3As shown, springs 5 are fixedly provided at the bottoms of several of the installation grooves 4, and the several springs 5 respectively abut against one ends of the support feet 3 extending into the installation grooves 4. Counterbore holes 7 communicating with the installation grooves 4 are formed at the tops of the several connecting rods 2. Bolts 8 are slidably arranged in the counterbore holes 7. Nuts 9 are fixedly provided at the bottoms of the several connecting rods 2. The several bolts 8 respectively slide through the corresponding support feet 3 and reinforcing rods 6 in sequence and are threadedly connected to the corresponding nuts 9. After the support feet 3 are connected to the connecting rods 2, and after the reinforcing rods 6 are installed, there will exactly be a hole for the bolt 8 to pass through. The nut 9 is correspondingly installed on the hole at the bottom of the connecting rod 2. Further reinforcement and fixation are achieved through the connection of the bolt 8 and the nut 9.

[0030] Working principle:

[0031] During installation, first, the corresponding support feet 3 are threadedly installed in the installation grooves 4 on the connecting rods 2. When screwed to the bottom, the connection groove 12 at the end of the support foot 3 faces downward. Further, the reinforcing rod 6 is threadedly installed in the support foot 3 and passes through the support foot 3 to be threadedly connected to the corresponding connecting rod 2. When the reinforcing rod 6 is screwed to the bottom, the bolt 8 is placed in the counterbore hole 7 and sequentially passes through the connecting rod 2, the support foot 3, and the reinforcing rod 6 downward to be threadedly connected to the nut 9. The multiple support feet 3 are installed in sequence. After the installation is completed, it can be assembled and used with the seat.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
