TECHNICAL FIELD

[0001] The utility model relates to chair leg processing technical field especially relates to a metal five-star chair leg. BACKGROUND

[0002] Five-star chair leg refers to the supporting structure at the bottom of a chair, usually composed of five leg tubes, shaped like a star. This design is commonly seen in office chairs, computer chairs and other seats that require stable support. The design of five-star chair leg can provide better balance and support, making the chair more stable and reducing the risk of tipping over.

SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a metal five-star chair leg to solve the technical problems of some metal five-star chair legs in the background art that need to be replaced in whole when damaged and lack of stability.

[0005] The above technical purpose of the utility model is realized by the following technical scheme:

[0006] A metal five-star chair leg, comprising a hollow tapered pipe of metal material and five branch pipes of metal material, the five branch pipes are fixedly connected with the hollow tapered pipe and uniformly arranged along the circumference of the hollow tapered pipe, and the side of each branch pipe away from the hollow tapered pipe is fixedly provided with a first magnetic attraction block; each branch pipe is externally sleeved with a leg pipe, and each leg pipe is internally fixedly provided with a second magnetic attraction block corresponding to the first magnetic attraction block; an installation piece is arranged between each leg pipe and the corresponding branch pipe, and the installation piece is used for fixing the leg pipe.

[0007] Working principle:

[0008] During installation, the five leg pipes are respectively sleeved on the outer periphery of the five branch pipes and are attached to the branch pipes, the second magnetic attraction block on the leg pipe attracts the first magnetic attraction block on the corresponding branch pipe, and then the installation assembly is used to fix the leg pipe on the center seat.

[0009] Beneficial effects:

[0010] In the scheme, by setting the first magnetic attraction block and the second magnetic attraction block, each leg pipe can be preliminarily positioned and fixed when installed on the branch pipe, preventing the installation piece from deviating when locking the leg pipe;

[0011] By setting the installation piece, the leg pipe is further locked and is convenient to install. Attached Figure Description

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figures 1 to 3 As shown, a metal five-star chair leg includes a hollow tapered tube 1 made of metal and five branch tubes 2 made of metal. The five branch tubes 2 are fixedly connected to the hollow tapered tube 1 and are evenly arranged around the circumference of the hollow tapered tube 1. A first magnetic block 3 is fixedly provided on the side of each branch tube 2 away from the hollow tapered tube 1. A foot tube 4 is sleeved on the outside of each branch tube 2. A second magnetic block 5 corresponding to the first magnetic block 3 is fixedly provided inside each foot tube 4. An installation component is provided between each foot tube 4 and the corresponding branch tube 2. The installation component is used to fix the foot tube 4.

[0019] In this solution, by setting the first magnetic block 3 and the second magnetic block 5, each foot tube 4 can be initially positioned and fixed when installed on the branch pipe 2, preventing the foot tube 4 from shifting when the mounting component locks it; by setting the mounting component, the foot tube 4 is further locked and installation is facilitated.

[0020] like Figure 1 and Figure 3As shown in the drawings, each of the foot pipes 4 comprises a mounting portion 401 and a working portion 402, each of the mounting portions 401 is composed of two mounting plates 4011, two connecting plates 4012 and a bottom plate 4013, the mounting plate 4011 of each mounting portion 401 is arc-shaped towards the side surface of the hollow tapered pipe 1, and the mounting plate 4011 of each mounting portion 401 abuts against the outer side surface of the hollow tapered pipe 1, so that the connection between each foot pipe 4 and the hollow tapered pipe 1 is more compact, greatly increasing the connection strength of the foot pipe 4 and the hollow tapered pipe 1, making the foot pipe 4 more solid and reliable.

[0021] As shown in the drawings, Figures 1 to 3 each of the working portions 402 is fixedly connected with the bottom plate of the corresponding mounting portion 401, each of the working portions 402 is provided with a cavity 6 towards the side surface of the corresponding mounting portion 401, each of the cavities 6 penetrates through the corresponding mounting portion 401, the second magnetic attraction block 5 is fixedly arranged in the cavity 6 of the working portion 402, and the first magnetic attraction block 3 penetrates through the corresponding mounting portion 401 and the cavity 6 of the corresponding working portion 402 and is attracted to the second magnetic attraction block 5. Therefore, when each foot pipe 4 is mounted on the branch pipe 2, the first magnetic attraction block 3 penetrates through the corresponding mounting portion 401 and the cavity 6 of the corresponding working portion 402, thereby preliminarily limiting and fixing the foot pipe 4, preventing the foot pipe 4 from deviating when the mounting member locks the foot pipe 4.

[0022] As shown in the drawings, Figure 2 and Figure 3 the mounting member comprises a threaded hole 7 arranged on the mounting portion 401 of the foot pipe 4 and the bottom surface of the branch pipe 2. The threaded hole 7 is used for threaded connection with a bolt, so as to firmly arrange the foot pipe 4 on the center seat composed of the hollow tapered pipe 1 and the five branch pipes 2.

[0023] As shown in the drawings, Figure 1 and Figure 2 the connecting portions of the two adjacent branch pipes 2 and the connecting portions of the branch pipes 2 and the hollow tapered pipe 1 are fixedly connected with reinforcing members 8. The arrangement of the reinforcing members 8 makes the foot pipe 4 arranged on the outer surface of the branch pipe 2 closely combined with the hollow tapered pipe 1, greatly increases the connection strength of the branch pipe 2 and the hollow tapered pipe 1, is solid and reliable, durable and has an attractive appearance. The reinforcing member 8 is made of plastic products. The reinforcing member 8 is made of plastic products, the plastic products are made of high-strength ABS plastic, which has the advantages of high tensile strength, wear resistance and excellent impact toughness.

[0024] Working principle:

[0025] During installation, the five foot pipes 4 are respectively sleeved on the outer periphery of the five branch pipes 2 and are attached to the hollow tapered pipe 1, in the process, the first magnetic attraction block 3 is passed through the corresponding installation portion 401 and is passed into the cavity 6 of the corresponding working portion 402, the first magnetic attraction block 3 is attracted to the second magnetic attraction block 5, then a bolt is screwed into the threaded hole 7 to fix the foot pipe 4 on the center seat.
