Description

Technical Field

[0001] This invention relates to the field of power maintenance tools, and in particular to a fastening fixture for power equipment terminals. Background Technology

[0002] Electrical connections are achieved by tightening cables with bolts. Inadequate or loose bolt tightening is a major cause of line overheating, arcing, and short-circuit tripping, making it a key focus of routine power system maintenance. Currently, ordinary fixed-angle wrenches and simple pliers are commonly used for tightening operations on-site.

[0003] Conventional wrenches and calipers have a fixed, integrated clamping head and handle, making the angle unadjustable. The internal terminals of distribution cabinets are densely packed, with cables and components severely obstructing the view. When facing terminals on the side, in the depths, or at corners, tools lack sufficient space to rotate, making it impossible to apply force directly to the bolts. This easily leads to damage to surrounding wiring, and some dead-end terminals are even impossible to work on.

[0004] Therefore, it is necessary to provide a fastening fixture for electrical equipment terminals to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a fastening fixture for electrical equipment terminals, solving the problems of dense terminal arrangement inside distribution cabinets, severe obstruction by cables and components, insufficient tool rotation space when facing terminals at the side, depth, and corners, making it impossible to apply force directly to the bolts. To address the above technical problems, this invention provides a fastening fixture for electrical equipment terminals, including a fastening fixture body, a locking component, and an auxiliary component. The fastening fixture body includes a caliper, a mounting base, a cylinder, a long handle, and a rotating shaft. The caliper is fixedly connected to one side of the mounting base, which is rotatably assembled with the cylinder via the rotating shaft. The right end of the cylinder is fixedly connected to the long handle, and the outer side of the long handle is covered with an anti-slip sleeve. The locking component is assembled at the rotational engagement position between the mounting base and the cylinder, and includes a limiting groove, a limiting rod, a first circular groove, a spring, and a circular block, used to lock and fix the deflection angle of the caliper. The auxiliary component is assembled on the long handle and includes a short handle, a second circular groove, a groove, and a protrusion. The short handle can cooperate with the long handle to achieve lateral auxiliary force application.

[0006] Preferably, the circular groove is formed on the end face of the cylinder, the limiting rod is slidably disposed inside the circular groove, the outer side of the limiting rod is fixed with a circular block, the spring is sleeved on the outside of the limiting rod, and the two ends of the spring respectively abut against the bottom of the circular groove and the circular block; the limiting groove is formed circumferentially on the end face of the mounting base, and the end of the limiting rod can be inserted into the limiting groove to complete the angle locking.

[0007] Preferably, the long handle has a circular groove, the inner wall of which is provided with a groove, and the end of the short handle has a protrusion that matches the groove. The protrusion is inserted into the groove to achieve detachable fixing of the short handle and the long handle.

[0008] Preferably, the caliper has a U-shaped opening structure, the caliper and the mounting base are integrally formed, the pivot passes through the center of the mounting base and the cylinder, and the caliper can rotate around the pivot at an angle of °~°.

[0009] Preferably, the groove and protrusion have a polygonal interlocking structure, the short handle is arranged perpendicular to the long handle, and the short handle can serve as a lateral force-bearing handle to apply force synchronously with the long handle.

[0010] Preferably, the anti-slip sleeve is a rubber anti-slip sleeve, which is tightly fitted onto the outer wall of the tail end of the long handle, and the outer surface of the anti-slip sleeve is provided with anti-slip texture.

[0011] Preferably, multiple sets of limiting grooves are evenly arranged in a ring along the end face of the mounting base, the end of the limiting rod is a cylindrical structure, and the limiting rod and the limiting groove are clearance-fitted.

[0012] Compared with related technologies, the power equipment terminal fastening fixture provided by the present invention has the following advantages:

[0013] The caliper can rotate at multiple angles and lock quickly, and can flexibly adapt to the wiring terminals in unconventional locations such as narrow, side, and deep positions inside the distribution cabinet, avoiding obstruction from surrounding lines, making it more adaptable to working in confined spaces.

[0014] Equipped with a detachable horizontal short handle, it can form a double-grip force application structure, which saves effort and increases torque by leveraging, making it easier to tighten bolts with high resistance and providing more stable force application when working at heights.

[0015] The spring-loaded angle locking structure is easy to operate, securely locks in place, and the caliper angle will not deflect on its own during the tightening process, ensuring stable clamping and positioning and preventing slippage or disengagement.

[0016] The long handle has a non-slip rubber sleeve at the end, making it easy to hold with one hand without slipping. The short handle can be detached and stored. The overall structure is compact and lightweight, making it very convenient to carry and use on site.

[0017] The overall structure is sturdy and durable, and the disassembly and adjustment steps are simple. It can be used with various high and low voltage terminal bolts for fastening, making it highly versatile. Attached Figure Description

The auxiliary component 3 includes a short handle 31, a circular groove 32, a groove 33, and a protrusion 34. The short handle 31 can cooperate with the long handle 14 to achieve lateral auxiliary force application.

[0025] The circular groove 23 is formed on the end face of the cylinder 13. The limiting rod 22 is slidably disposed inside the circular groove 23. The outer side of the limiting rod 22 is fixed with a circular block 25. The spring 24 is sleeved on the outside of the limiting rod 22. The two ends of the spring 24 abut against the bottom of the circular groove 23 and the circular block 25, respectively. The limiting groove 21 is formed circumferentially on the end face of the mounting base 12. The end of the limiting rod 22 can be inserted into the limiting groove 21 to complete the angle locking.

[0026] The long handle 14 has a circular groove 32, and the inner wall of the circular groove 32 is provided with a groove 33. The end of the short handle 31 is provided with a protrusion 34 that matches the groove 33. The protrusion 34 is inserted into the groove 33 to achieve detachable fixation between the short handle 31 and the long handle 14.

[0027] The caliper 11 has a U-shaped opening structure. The caliper 11 and the mounting base 12 are integrally formed. The rotating shaft 15 passes through the center of the mounting base 12 and the cylinder 13. The caliper 11 can rotate around the rotating shaft 15 at an angle of 0° to 90°.

[0032] Pull the limit rod 22 outward to compress the spring 24 so that the end of the limit rod disengages from the limit groove 21. Then, rotate the caliper 11 around the pivot 15 and adjust the clamping orientation of the caliper as needed to adapt to the terminal position in the narrow space inside the cabinet. After the angle is adjusted, release the limit rod, and the spring will rebound to lock the limit rod into the corresponding limit groove, thus completing the angle locking.

[0033] Engage the U-shaped caliper 11 on the outside of the terminal bolt, and rotate and tighten the long handle 14 with the anti-slip sleeve 4 at the end to complete the tightening of the terminal bolt.

The short handle is held and applied laterally in a synchronous manner, using the lever principle to increase the torque. After the operation is completed, the short handle can be removed directly for easy storage.
