Embodiment Construction

[0014] In order to solve the overall installation and disassembly of screws in the prior art, because the screws are long, they need to be completely disassembled before disassembly can be realized, which is time-consuming and laborious. On the other hand, the design of the overall structure of the screws is easy to rust, and it is difficult to disassemble after long-term use.

[0015] In order to solve the above problems, the technical solutions of the present application will be specifically described below in conjunction with the accompanying drawings of the present application.

[0016] Such as figure 1 , figure 2 , image 3 As shown, the split screw described in this application is composed of a screw head 1 and a screw rod 2. During use, the screw head 1 can be installed first, or the screw rod 2.5 of the screw rod 2 can be screwed into the screw head 1 end. The cylindrical cavity structure 1.1 is connected and then installed. The inside of the end of the screw head ...

Abstract

The invention belongs to the technical field of decoration building materials, and particularly relates to a novel split type screw. The split type screw is composed of a screw head and a screw rod, acylindrical cavity structure is arranged on the inner side of the tail end of the screw head, internal threads are arranged on the inner wall of the cylindrical cavity structure, and an inward-sunkenfastening opening is formed in the bottom of the inner side of the cylindrical cavity structure; external threads matched with the internal threads of the cylindrical cavity structure are arranged onthe outer side of a screw rod body of the screw rod, the screw rod body can be screwed into the cylindrical cavity structure through cooperation of the external threads and the internal threads of the cylindrical cavity structure, and connection and fixation of the screw head and the screw rod are achieved; the thread pitch of the outer side of the screw head is larger than the thread pitch of the internal threads of the inner wall of the cylindrical cavity structure and the external threads of the outer side of the screw rod body. Mounting and dismounting are more convenient, and the screw is effectively prevented from being rusted or slipping.

Description

technical field [0001] The invention belongs to the technical field of decoration and building materials, and in particular relates to a novel split screw. Background technique [0002] In the decoration process, the gypsum board connection or the steel structure connection is usually fixed by screws. However, after the screws in the prior art are fixed, if you want to disassemble, you must remove all the screws to complete the disassembly, especially for some smaller parts. Long screws are very inconvenient to disassemble. In the prior art, there is no screw that can be fixed and installed conveniently, and is more convenient to disassemble during later disassembly. Contents of the invention [0003] The invention provides a novel split screw, which solves the technical problem of inconvenient disassembly of the screw in the prior art. [0004] A split screw, consisting of a screw head and a screw shaft, the inside of the end of the screw head is provided with a cylindri...
