Description

Technical Field

[0001] This utility model relates to the field of clamp installation technology, and in particular to a clamp wrench. Background Technology

[0002] Traditional clamp connections typically use clamps with raised protrusions. When connecting pipes or equipment, these protrusions are exposed, making them susceptible to environmental factors such as corrosion and impacts, leading to clamp damage or connection failure. Furthermore, traditional clamp connections suffer from the following drawbacks: maintenance of the connected pipes or equipment requires locating the raised protrusions before disassembly, a cumbersome process. To address these issues, concealed clamps have emerged. However, their installation currently requires specialized tools, and traditional wrenches struggle to provide precise positioning, resulting in low installation efficiency and potential clamp damage. Therefore, a dedicated wrench for concealed clamps is urgently needed to improve installation accuracy and ease of operation. Utility Model Content

A sliding groove extending along its length and located between the first boss and the second boss is opened on the side of the wrench body. At the same time, a threaded hole communicating with the sliding groove is opened at one end of the first boss.

[0007] A slider is slidably connected in the groove. The slider has a flange extending to the outside of the groove opening. A second pin hole parallel to the first pin hole is formed on the flange.

[0008] Positioning pins, wherein two positioning pins are provided and are respectively inserted into the first pin hole and the second pin hole;

[0009] An adjusting bolt, which is screwed into the threaded hole.

[0010] As a further improvement of this utility model, the wrench body is a split structure, including a first body and a second body. The first body has a first groove located between a first boss and a second boss. The second body is connected to the first body by a plurality of fasteners. The second body and the first groove form the sliding groove.

[0011] As a further improvement of this utility model, the second main body is an arc plate structure with an L-shaped cross-section. The second main body is provided with a plurality of second connecting holes, and the first main body is provided with a plurality of first connecting holes corresponding to the positions of each of the second connecting holes. The first main body and the second main body are fastened together by fasteners passing through the first connecting holes and the second connecting holes in sequence.

[0012] As a further improvement of this utility model, the fastener is a countersunk bolt.

[0013] As a further improvement of this utility model, the threaded hole is opened at the end of the wrench body away from the first pin hole.

[0014] As a further improvement of this utility model, both the wrench body and the slider are made of metal.

[0015] The beneficial effects of this utility model are: through the design of double positioning pins and adjustable slider, this utility model can accurately fit the mounting holes of the hidden clamp, thereby improving the installation efficiency. By adjusting the bolts, the tightness of the clamp can be precisely controlled to ensure the installation accuracy. Attached Figure Description
