Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a bolt which is easy to replace and disassemble. Background Art

[0002] A bolt is a mechanical part, mainly composed of a head and a screw (a cylinder with external threads). It needs to be used in conjunction with a nut to fasten and connect two parts with through holes. Bolt connection is a detachable connection, that is, when the nut is unscrewed from the bolt, the two parts can be separated. However, the existing bolts cannot be easily removed during use, and the screwing and clamping ends are easily worn and deformed during the screwing process after a long fixed connection time, causing the bolt to slip when it is screwed and removed, making it inconvenient to replace and disassemble the used bolts. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bolt that is easy to replace and disassemble, comprising a threaded connection column, an end head, a fixing bolt and an auxiliary screwing clamp, wherein the end head is fixedly connected to the upper end of the threaded connection column, the end head is arranged in a hexagonal column, and the auxiliary screwing clamp is fixedly connected to each outer end of the end head through the fixing bolt.

[0005] Preferably, a screwing slot is provided in the middle of the upper end of the end head.

[0006] Preferably, the bottom end of the auxiliary screwing clamp is fixedly connected with a supporting limit plate.

[0007] Preferably, the external clamping of the auxiliary screwing clamping plate is provided with a clamping screwing sleeve.

[0008] Preferably, the fixing and screwing sleeve is arranged in a hexagonal prism shape, and the bottom end of the fixing and screwing sleeve is located on the supporting and limiting plate.

[0009] Preferably, a screwing handle is fixedly connected to the middle of both ends of the clamping screwing sleeve.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model discloses a tool can be used to assist in screwing the end head and the threaded connection column to be replaced by a screwing slot. When the end head and the threaded connection column need to be repeatedly removed and replaced during use, the fixing screw sleeve is fixed on the outside of the auxiliary screwing clamp plate, and the bottom end of the fixing screw sleeve is supported and limited by the supporting limit plate, so that when the end head needs to be repeatedly screwed and removed for use, the threaded connection column and the end head can be conveniently screwed and removed by the screwing handle. When the threaded connection column and the end head need to be removed and replaced after being fixed for a long time, an auxiliary screwing clamp plate is fixed on the outside of the end head by a fixing bolt, and the end head can be conveniently screwed by the auxiliary screwing clamp plate without causing the end head to be deformed during the screwing process, so that the threaded connection column and the end head can be conveniently and labor-savingly screwed and removed for use repeatedly, and the threaded connection column and the end head can be stably and conveniently removed and replaced after being firmly fixed for a long time.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides an embodiment: a bolt that is easy to replace and disassemble, including a threaded connection column 3, an end head 4, a fixing bolt 6 and an auxiliary screwing clamp 7, the end head 4 is fixedly connected to the upper end of the threaded connection column 3, the end head 4 is arranged in a hexagonal column, and the auxiliary screwing clamp 7 is fixedly connected to each outer end of the end head 4 through the fixing bolt 6.

[0018] A screwing slot 5 is provided in the middle of the upper end of the terminal 4, so that the terminal 4 can be screwed off in various ways.

[0019] The bottom end of the auxiliary screwing clamping plate 7 is fixedly connected with a support limit plate 8 to play a supporting role.

[0020] The external clamping of the auxiliary screwing clamping plate 7 is provided with a clamping screwing sleeve 2 to play the role of auxiliary clamping and screwing.

[0021] The clamping and screwing sleeve 2 is arranged in a hexagonal prism shape, and the bottom end of the clamping and screwing sleeve 2 is located on the support and limiting plate 8, which plays the role of clamping and limiting support.

[0022] The middle parts of both ends of the clamping screwing sleeve 2 are fixedly connected with a screwing handle 1, which is convenient for screwing the clamping screwing sleeve 2 to rotate the end head 4.

[0023] Working principle: During use, since a screwing slot 5 is provided at the middle part of the upper end of the end head 4, the end head 4 and the threaded connection column 3 can be screwed out and replaced with the aid of a tool by screwing the slot 5. When the end head 4 and the threaded connection column 3 need to be repeatedly removed and replaced during use, the fixing screwing sleeve 2 is fixed to the outside of the auxiliary screwing clamping plate 7, and the bottom end of the fixing screwing sleeve 2 is supported and limited by the support limit plate 8, so that when the end head 4 needs to be repeatedly screwed out and used, the screw can be conveniently removed by using the screwing handle 1. The threaded connecting column 3 and the end head 4 are screwed off. When the threaded connecting column 3 and the end head 4 need to be removed and replaced after being fixed for a long time, an auxiliary screwing clamp 7 is fixed on the outside of the end head 4 by fixing bolts 6. The auxiliary screwing clamp 7 can make it convenient for the tool to screw the end head 4 without causing the end head 4 to deform during the screwing process, so that the threaded connecting column 3 and the end head 4 can be conveniently and repeatedly screwed off and used with little effort, and the threaded connecting column 3 and the end head 4 can be stably and conveniently removed and replaced after being firmly fixed for a long time.
