Description

Technical Field

[0001] This utility model belongs to the field of building structure renovation and reinforcement technology, specifically relating to a clamp for unidirectional bolts. Background Technology

[0002] In the process of joining two objects, welding, riveting, or bolting are commonly used. Among these, bolting is the most widely used method due to its simplicity, ease of joining and separating, and the absence of thermal deformation. This bolting method typically involves inserting a bolt into a threaded hole in the joined parts and securing it with a nut on the back. However, in existing technologies, there are situations where the back of the joined parts is a closed space, inaccessible by hand or tools, making conventional bolt-based joining methods impossible. This led to the development of one-way bolts. However, one-way bolts lack dedicated clamping tools, making installation inconvenient in some restricted working conditions and reducing connection efficiency. Therefore, there is an urgent need for a connector for one-way bolts. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a clamp for one-way bolts. The clamp has a simple structure and low manufacturing cost. It can effectively clamp the end of the one-way bolt, which can significantly improve the work efficiency of the installation or removal process of one-way bolts. At the same time, it helps to improve the safety factor during the operation.

[0004] To achieve the above objectives, this utility model provides a clamp for one-way bolts, comprising a clamp body and two clamping blocks;

[0005] The clamp body includes a U-shaped connecting section and two curved arm sections; the two curved arm sections are arranged side by side, and their first ends are respectively fixedly connected to the two ends of the U-shaped connecting section;

[0006] Two clamping blocks are fixedly connected to each other on the end faces of the second ends of the two curved arm sections.

[0007] Furthermore, in order to effectively adapt to the trapezoidal groove at the end of the one-way bolt, the clamping block has a trapezoidal cross-section. Making the clamping block trapezoidal allows for better fitting with the trapezoidal groove at the end of the one-way bolt, ensuring a tight fit between the one-way bolt and the clamp during clamping. This prevents the one-way bolt from accidentally detaching during clamping, installation, or removal, ensuring operational stability and reliability.

[0008] Furthermore, to facilitate clamping operations under gripping conditions, the curved arm section is L-shaped.

[0009] As a preferred embodiment, the clamp body is a one-piece structure made of an elastic rod that has been bent multiple times.

[0010] As a preferred embodiment, the clamping block is integrally formed at the end of the clamp body.

[0011] Furthermore, to ensure the clamping effect and to ensure that the clamp as a whole has good elastic recovery ability, the clamp body is made of high elasticity steel.

[0012] In this practical trapezoidal clamp, two bent arm sections are fixedly connected side-by-side to both ends of a U-shaped connecting section to form a clamp body, which provides a gripping area for the operator to hold, allowing for convenient gripping. Two clamping blocks are fixedly connected to the ends of the two bent arm sections, facilitating the clamping of the one-way bolt using the two relatively distributed clamping blocks. This effectively extends the clamping range, allowing the operator to perform one-way bolt installation or removal operations more flexibly and conveniently within confined spaces, greatly improving work efficiency and significantly enhancing the safety factor during operation.

[0013] This clamp has a simple structure and low manufacturing cost. It can effectively clamp the end of a one-way bolt, which can significantly improve the work efficiency of the installation or removal of one-way bolts. At the same time, it helps to improve the safety factor during the operation. Attached Figure Description

[0017] The present invention will be further described below.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a clamp for a one-way bolt, including a clamp body 1 and two clamping blocks 2;

[0019] The clamp body 1 includes a U-shaped connecting section 3 and two curved arm sections 4; the two curved arm sections 4 are arranged side by side, and their first ends are respectively fixedly connected to the two ends of the U-shaped connecting section 3.

[0020] Two clamping blocks 2 are fixedly connected to each other on the end faces of the second ends of the two curved arm sections 4.

[0021] To effectively adapt to the trapezoidal groove at the end of the one-way bolt, the clamping block 2 has a trapezoidal cross-section. This trapezoidal cross-section allows for better fitting with the trapezoidal groove at the end of the one-way bolt, ensuring a tight fit between the one-way bolt and the clamp during clamping. This prevents accidental detachment of the one-way bolt during clamping, installation, or removal, thus ensuring operational stability and reliability.

[0022] To facilitate clamping operations under gripping conditions, the curved arm section 4 is L-shaped.

[0023] As a preferred embodiment, the clamp body 1 is a one-piece structure, which is made of an elastic rod that has been bent multiple times.

[0024] As a preferred embodiment, the clamping block 2 is integrally formed at the end of the clamp body 1.

[0025] To ensure effective clamping and to ensure that the clamp as a whole has good elastic recovery capability, the clamp body 1 is made of high elasticity steel.

[0026] Among them, the upper end of the one-way bolt 5 has a threaded section 6, and two trapezoidal grooves 7 are opened on opposite sides of the upper end of the threaded section 6.

[0027] Instructions for use: When clamping the one-way bolt 5, separate the ends of the two curved sections 4 to the sides, so that the two clamping blocks 2 are inserted into the two trapezoidal grooves 7 from both sides of the threaded section 6 on the one-way bolt 5, and apply pressure to the ends of the two curved sections 4 to ensure the stability of the clamping.

[0028] In this practical trapezoidal clamp, two bent arm sections are fixedly connected side-by-side to both ends of a U-shaped connecting section to form a clamp body, which provides a gripping area for the operator to hold, allowing for convenient gripping. Two clamping blocks are fixedly connected to the ends of the two bent arm sections, facilitating the clamping of the one-way bolt using the two relatively distributed clamping blocks. This effectively extends the clamping range, allowing the operator to perform one-way bolt installation or removal operations more flexibly and conveniently within confined spaces, greatly improving work efficiency and significantly enhancing the safety factor during operation.

[0029] This clamp has a simple structure and low manufacturing cost. It can effectively clamp the end of a one-way bolt, which can significantly improve the work efficiency of the installation or removal of one-way bolts. At the same time, it helps to improve the safety factor during the operation.
