Description

Technical Field

[0001] The utility model belongs to a bolt which is convenient for disassembly and assembly. Background Technique

[0002] The original production process of phosphite is divided into three sections: esterification - acid discharge - distillation. According to the purpose of the new process, it needs to be reduced to two sections: esterification - acid discharge. Since the feeding of phenol is slightly excessive, if the excessive phenol is completely removed by subsequent filtration, it will not only cause waste of raw materials, but also generate a large amount of solid waste. Therefore, it is necessary to discharge and recycle this slightly excessive phenol during the late stage of acid discharge. For this reason, we propose a bolt which is convenient for disassembly and assembly. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bolt which is convenient for disassembly and assembly, so as to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a bolt which is convenient for disassembly and assembly, including a bolt head, a screw rod, a gasket and a rotating component. The bolt head is arranged at the top of the screw rod. The gasket is arranged between the screw thread on the surface of the screw rod and the bolt head. The rotating component is used to rotate the bolt head so that the screw thread on the surface of the screw rod drills into the installation surface.

[0005] Preferably, a connecting column extends outward from the upper surface of the bolt head. The rotating component includes a fixed column arranged outside the connecting column, and a jack which is adapted to the connecting column is opened in the fixed column.

[0006] Preferably, a positioning block is arranged on the upper surface of the fixed column. The positioning block is circular, and a rotating plate is arranged at equal intervals around the outside of the positioning block.

[0007] Preferably, a through hole is opened at one end of the rotating plate away from the positioning block.

[0008] Preferably, friction contacts are arranged on the outside of the bolt head.

[0009] Preferably, internal threads are opened on the inner wall of the jack, and external threads which are adapted to the internal threads are opened on the outer wall of the connecting column.

[0010] Preferably, the installation direction of the connecting column is the same as that of the screw rod.

[0011] Technical effects and advantages of the present utility model: For this bolt that is convenient for disassembly and assembly, when the friction contacts on the outer sidewall of the bolt head are worn to a certain extent after long-term use, the jack opened in the fixing column can be aligned with the connecting column at this time. As the internal thread in the jack is adapted to the external thread on the outer sidewall of the connecting column, rotating the fixing column can fix the fixing column on the connecting column. When installing the screw rod, initially rotating the rotating plate can drive the fixing column to rotate, driving the connecting column and the screw rod to rotate to complete the installation of the screw rod. When the screw rod rotates to two-thirds into the installation surface, a fixing rod can be inserted into the through hole to facilitate driving the rotation of the bolt head. The overall structure is simple, which can ensure the installation efficiency of the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0018] For the convenience of installing the bolt as a whole, refer to Figure 1 、 Figure 2 and Figure 3As shown, it includes a bolt head 1, a screw rod 2, a gasket 3 and a rotating assembly, wherein the bolt head 1 is arranged at the top of the screw rod 2, and the gasket 3 is arranged between the surface thread of the screw rod 2 and the bolt head 1, and the rotating assembly is used to rotate the bolt head 1 so that the surface thread of the screw rod 2 drills into the installed surface. When the friction contact 10 on the outer wall of the bolt head 1 is worn to a certain extent after long-term use, the socket 6 opened in the fixing column 5 can be aligned to the connecting column 4. As the internal thread in the socket 6 is adapted to the external thread on the outer wall of the connecting column 4, the fixing column 5 can be fixed on the connecting column 4 by rotating the fixing column 5. When the screw rod 2 is installed, the initial rotation of the rotating plate 8 can drive the fixing column 5 to rotate, drive the connecting column 4 and the screw rod 2 to rotate, and complete the installation of the screw rod 2. When the screw rod 2 is rotated to two-thirds of the installed surface, the fixing rod can be used to be inserted into the through hole 9 to facilitate driving the rotation of the bolt head 1. The overall structure is simple and can ensure the installation efficiency of the screw rod 2.

[0019] To improve the convenience of installing bolts, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper surface of the bolt head 1 has a connecting column 4 extending outward, and the rotating assembly includes a fixed column 5 arranged outside the connecting column 4, and a socket 6 adapted to the connecting column 4 is provided in the fixed column 5. By aligning the connecting column 4 with the socket 6 and inserting the connecting column 4 into the socket 6, the installation of the fixed column 5 can be completed. A positioning block 7 is provided on the upper surface of the fixed column 5. The positioning block 7 is circular, and a rotating plate 8 is provided at equal intervals around the outer side of the positioning block 7. As the rotating plate 8 is rotated, the fixed column 5, the connecting column 4 and the bolt head 1 can be driven to rotate, so that the bolt can be installed. At this time, even if the friction contact 10 is worn and cannot rotate, the installation and removal of the bolt can be completed. A through hole 9 is provided at one end of the rotating plate 8 away from the positioning block 7. When the screw rod 2 is inserted into two-thirds of the installation surface, the fixed rod can be plugged into the socket 6, which is convenient for the staff to drive the bolt head 1. The outer side of the bolt head 1 is provided with a friction contact 10, and the friction contact 10 is used to increase the friction force, so as to facilitate the rotation of the bolt head 1 and drive the rotation of the screw rod 2. The inner wall of the insertion hole 6 is provided with an internal thread, and the outer wall of the connecting column 4 is provided with an external thread that matches the internal thread. The internal thread and the external thread are matched to facilitate the installation of the fixed block on the connecting block. The installation direction of the connecting column 4 is the same as the installation direction of the screw rod 2. At this time, rotating the rotating plate 8 can make the fixed block and the connecting block more tightly connected, and will drive the screw rod 2 to rotate and insert in the same direction. When the bolt needs to be removed, the friction contact 10 can be abutted by other tools.

[0020] In use, first, when the friction contacts 10 on the outer wall of the bolt head 1 are worn to a certain extent after long-term use, the jack 6 opened in the fixing column 5 can be aligned with the connecting column 4 at this time. As the internal thread in the jack 6 is adapted to the external thread on the outer wall of the connecting column 4, rotating the fixing column 5 can fix the fixing column 5 on the connecting column 4. When the screw 2 is installed, initially rotating the rotating plate 8 can drive the fixing column 5 to rotate, driving the connecting column 4 and the screw 2 to rotate, completing the installation of the screw 2. When the screw 2 rotates to two-thirds into the installation surface, a fixing rod can be inserted into the through hole 9 to drive the rotation of the bolt head 1.

[0021] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
