Description

Technical Field

[0001] The utility model belongs to the technical field of torque bolts, and more specifically, particularly relates to a torque bolt with an improved pressing block structure. Background Art

[0002] A torque bolt is a bolt commonly used for connection and fixing. Its main function is to generate pre-pressure through the torque of the force, thereby achieving the tightening of the connection.

[0003] For example, the Chinese invention patent with patent number 201810972217.7 provides an anti-loosening bolt assembly, which is provided with a bolt, an anti-slip pressure plate and a top pressure part. When in use, the anti-slip pressure plate at the bottom of the bolt is moved downward by rotating the bolt, and the cable is tightened by the top pressure part at the bottom of the anti-slip pressure plate; however, when fixing the cable, the traditional torque bolt needs to be tightened and fixed, and the part where the cable is tightened generally has corners, which can easily cause damage to the surface of the cable. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a torque bolt with an improved pressure block structure to solve the technical problem in the prior art that traditional torque bolts need to be compressed and fixed when fixing cables, and the parts where the cables are compressed generally have corners, which can easily cause damage to the surface of the cable.

[0005] The purpose and effect of the torque bolt with improved pressure block structure of the utility model are achieved by the following specific technical means:

[0006] A torque bolt with an improved pressing block structure comprises a bolt body and a bolt pressing block;

[0007] A connecting column is fixedly provided at the bottom end of the bolt body, and the bottom end of the connecting column is connected to the bolt pressure block. A cavity is opened at the bottom of the bolt pressure block, and one or more groups of arc surfaces are arranged on the circumference of the cavity. The bolt body and the connecting column are an integrally formed structure, and a protective component is arranged on the top of the bolt body.

[0008] In a preferred embodiment, one or more groups of arc surfaces surround the circumference of the cavity.

[0009] In a preferred embodiment, one or more groups of arc surfaces are all wavy.

[0010] In a preferred embodiment, the connecting column and the bolt pressing block are sleeve-connected.

[0011] In a preferred embodiment, the protection assembly includes a breakable fracture column, and the top of the bolt body is provided with the fracture column.

[0012] In a preferred embodiment, the protection component further includes a tightening nut, and the top of the fracture column is fixedly connected with the tightening nut.

[0013] In a preferred embodiment, the breaking torque of the breaking column is 120N.

[0014] In a preferred embodiment, the fracture column is made of steel.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. Through the setting of the bolt pressing block, when the torque bolt is used, through a group or multiple arc surfaces at the bottom of the bolt pressing block, the group or multiple arc surfaces are all wavy, so that the arc surfaces have a limiting effect, so that the contact area between the bolt pressing block and the cable is increased and more fitted, so that when tightening the bolt to fix the cable, it is possible to avoid direct contact between the corners and the cable, so that the pressure block and the cable can have a smooth transition without damaging the cable surface, thereby effectively reducing damage to the cable surface and better protecting the integrity of the cable. The problem that the traditional torque bolt is prone to damage to the cable surface when fixing the cable is solved, ensuring that the cable can be stably and safely fixed.

[0017] 2. Through the setting of the protection component, when the torque bolt is used, the breaking torque of the breaking column is 120N through the detachable breaking column and the tightening nut. It is made of steel material. When the torque reaches 120N, the breaking column can automatically break off, which plays a protective role, avoids damage to the cable caused by excessive torsion, and prevents damage to the cable, thereby improving the safety and reliability of the torque bolt.

[0018] 3. Through the fitting connection of the bolt pressure block and the connecting column, when the bolt is tightened, when the pressure block does not contact or just starts to contact the cable, the friction between the pressure block and the connecting column causes the pressure block to rotate with the bolt, and the arc surface design can effectively avoid damage to the cable surface. When tightening gradually, when the friction between the pressure block and the cable is greater than the friction between it and the connecting column, the pressure block cannot rotate.

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 4 As shown:

[0028] The utility model provides a torque bolt with an improved pressure block structure, comprising a bolt body 11 and a bolt pressure block 12; a connecting column 13 is fixedly arranged at the bottom end of the bolt body 11, the bottom end of the connecting column 13 is connected to the bolt pressure block 12, a cavity 14 is opened at the bottom of the bolt pressure block 12, and one or more groups of arc surfaces 15 are arranged on the circumference of the cavity 14. The two groups of arc surfaces 15 can increase the contact area with the cable, thereby improving the firmness and stability of the fixation. In addition, the protection component on the top of the bolt body 11 provides additional safety protection for the torque bolt to prevent the cable from being damaged.

[0029] Please refer to Figure 4 As shown, one or more groups of arc surfaces 15 surround the structure of the cavity 14, so that the arc surface 15 forms a continuous and smooth surrounding structure in the cavity 14, so that the pressure block and the cable can have a smooth transition without damaging the cable surface, which not only enhances the friction between the bolt pressure block 12 and the cable, but also can more evenly distribute the fixing force, effectively reduce the pressure on the cable, and extend the service life of the cable. The bolt pressure block 12 is fitted and connected with the connecting column 13. During the process of tightening the bolt, when the bolt pressure block 12 does not contact or just starts to contact the cable, the friction between the bolt pressure block 12 and the connecting column 13 causes the bolt pressure block 12 to rotate with the bolt, and the arc surface design can effectively avoid damage to the cable surface; when gradually tightening, when the friction between the bolt pressure block 12 and the cable is greater than the friction between it and the connecting column 13, the bolt pressure block 12 cannot rotate.

[0030] Please refer to Figure 2 and Figure 3As shown, one or more arc surfaces 15 are all wavy, which not only gives them a limiting effect, but also enhances the fit and contact area with the cable, and can effectively avoid the corners of the bolt pressing block 12 directly causing damage to the cable when contacting the cable, but achieves a smooth transition between the bolt pressing block 12 and the cable, ensuring that the cable surface is not damaged; in the process of tightening the torque bolt to fix the cable, the wavy arc surface 15 can fit the cable surface more closely, effectively reducing the friction and pressure on the cable surface, thereby protecting the integrity of the cable; it not only solves the problem that traditional torque bolts are prone to damage the cable surface when fixing the cable, but also ensures that the cable can be fixed stably and safely.

[0031] Please refer to Figure 2 and Figure 3 As shown, the design of the protection component takes into account the need to disconnect in specific circumstances, and includes a detachable breaking column 21. This breaking column 21 is arranged on the top of the bolt body 11 and plays a very important role. When the pressure block contacts the surface of the cable, the bolt can continue to be tightened to reach a preset pressure range. When the operator continues to twist, the breaking column 21 will work and disconnect from the bolt body 11, thereby effectively protecting the cable from unnecessary damage and improving the overall stability and safety. By providing the breaking column 21, when the connection with the bolt body 11 is disconnected, the operator can ensure the integrity of the cable during the installation and fixing process.

[0032] Please refer to Figure 3 As shown, the design of the protection component not only includes a detachable breaking column 21, but also a tightening nut 22. The tightening nut 22 is fixedly connected to the top of the breaking column 21. The operator can operate the bolt body 11 by tightening the nut 22. The setting of the tightening nut 22 enables the breaking column 21 to play a better role. When the operator twists the tightening nut 22, when the torque applied to it is greater than the disconnection torque of the breaking column 21, the connection between the tightening nut 22 and the bolt body 11 will be disconnected to protect the cable from damage; after the breaking column 21 is disconnected, the operator can still operate through the screw head on the top of the bolt body 11.

[0033] As an important part of the protection component, the breaking column 21 has the characteristic of a breaking torque of 120N. Since the breaking column 21 is made of steel, it can automatically break when the torque reaches 120N, playing an important protective role; when the external torsional force reaches the set breaking torque, the breaking column 21 will break quickly, thereby effectively preventing excessive torsion from causing damage to the cable. This structure not only protects the integrity of the cable, but also avoids equipment failures and safety hazards caused by excessive torsion; through the setting of the breaking column 21, the safety and reliability of the torque bolt are effectively improved, ensuring the normal operation of the equipment and cables; the influence of external forces on the device is fully considered, and effective protection of the cable is achieved by reasonably setting the breaking torque.

[0034] Specific usage and function of this embodiment: when the operator needs to install or remove the torque bolt, he first needs to use a wrench or other tools to tighten the tightening nut 22 to install or remove the torque bolt; when the applied torque is greater than the disconnection torque 120N of the breaking column 21, the breaking column 21 will automatically disconnect, so that the connection between the tightening nut 22 and the bolt body 11 is disconnected, thereby protecting the cable from damage.

[0035] After the broken column 21 is broken, even if the connection between the tightening nut 22 and the bolt body 11 has been released, the operator can still operate through the screw head on the top of the bolt body 11, which means that even when the broken column 21 plays a protective role, the operator can still continue the disassembly or installation work, ensuring the continuity and convenience of the operation.

[0036] The bolt pressing block 12 at the bottom of the bolt body 11 can effectively clamp and fix the cable. What is more important is that two groups of wavy arc surfaces 15 are provided on the bolt pressing block 12, so that the two groups of arc surfaces 15 have a good limiting effect, thereby significantly increasing the contact area between the bolt pressing block 12 and the cable, and being able to achieve a tighter fit; when tightening the torque bolt to fix the cable, due to the existence of the wavy arc surface 15, it is possible to avoid direct contact between the corners and the cable, so that a very smooth transition can be achieved between the bolt pressing block 12 and the cable, and no damage will be caused to the cable surface; in this way, the damage to the cable surface can be effectively reduced, the integrity of the cable can be better protected, and the problem that the traditional torque bolt is prone to damage to the cable surface when fixing the cable is solved, which effectively ensures that the cable can be stably and safely fixed.

Many modifications and variations will be apparent to those of ordinary skill in the art.
