Description

Technical Field

[0001] This utility model relates to the technical field of screwing tools, and in particular to a screwing tool for explosion-proof flexible pipe joints. Background Technology

[0002] In gas stations or other locations with explosion-proof requirements, explosion-proof flexible conduits are used at the inlet and outlet of electrical distribution boxes to protect the lines and reduce the incidence of explosions caused by electrical sparks. However, for densely packed explosion-proof flexible conduit joints, the small spacing between them makes it difficult to grip the joints with a regular wrench. Even if the wrench is engaged, the limited range of motion makes tightening difficult, affecting the efficiency of disassembling and assembling the joints and limiting their usability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-3 This utility model discloses an explosion-proof flexible pipe joint tightening tool, comprising an internally threaded pipe 1, a threaded rod 2 screwed onto the internally threaded pipe 1, a first V-shaped clamp 3 rotatably mounted on the end of the threaded rod 2, a malleable metal strip 4 detachably mounted on the end of the internally threaded pipe 1, and a second V-shaped clamp 5 mounted on the malleable metal strip 4. Furthermore, the malleable metal strip 4 is detachably connected to the internally threaded pipe 1 by bolts. The malleable metal strip 4 is preferably a thin-walled metal strip with a certain strength and malleability, such as an iron metal strip or other alloy strip.

[0024] For details, please refer to Figure 5 The end of the internally threaded tube 1 is symmetrically provided with a capped shaft 6. The plastic metal strip 4 is provided with a first through hole 7 and a second through hole 8. The capped shaft 6 includes a rod and a cap with an outer diameter larger than the rod. The first through hole 7 and the second through hole 8 are interconnected. The inner diameter of the first through hole 7 allows the cap to pass through, and the inner diameter of the second through hole 8 matches the outer diameter of the rod.

[0025] Specifically, a rotating rod 9 is provided at the end of the threaded rod 2 that is away from the first V-shaped clip 3.

[0026] Specifically, the threaded rod 2 is provided with a sliding hole 10 that allows the rotating rod 9 to slide, and both ends of the rotating rod 9 are provided with limit balls 11.

[0027] Specifically, the internally threaded tube 1 is equipped with a rubber grip sleeve 14.

[0028] The explosion-proof flexible pipe joint screwing tool provided in this embodiment has an adjustable gap between the first V-shaped clamp 3 and the second V-shaped clamp 5, thereby adapting to the screwing operation requirements of explosion-proof flexible pipe joints of various sizes. The cap on the capped shaft 6 passes through the first through hole 7, while the shaft slides into the second through hole 8, which can quickly realize the disassembly between the plastic metal strip 4 and the internally threaded pipe 1, improving the ease of disassembly between the plastic metal strip 4 and the internally threaded pipe 1. The threaded rod 2 can be rotated more effortlessly by rotating the rotating rod 9. By adjusting the gap between the end of the rotating rod 9 and the central axis of the internally threaded pipe 1, the operator can apply force to the end of the rotating rod 9 and adjust the rotation of the threaded rod 2 by applying a small force with the index finger and thumb, further improving the ease of operation. The rubber grip 14 can increase the friction between the operator's hand and the internally threaded pipe 1, improving the operator's grip comfort on the internally threaded pipe 1.

[0029] Example 2

[0030] The screwing tool for the explosion-proof flexible pipe joint provided in Example 1 has been further optimized. For details, please refer to... Figure 4It also includes a flexible strip 12, the end of which is connected to the internally threaded pipe 1; furthermore, the width of the flexible strip 12 is at least 1 cm to ensure that there is sufficient contact area between the flexible strip 12 and the explosion-proof flexible pipe joint.

[0031] Specifically, a hook 13 is provided at the end of the flexible strip 12 away from the internally threaded tube 1.

[0032] The explosion-proof flexible pipe joint tightening tool provided in this embodiment allows the explosion-proof flexible pipe joint to be loosened initially. At this time, the explosion-proof flexible pipe joint is in an active state. The malleable metal strip 4 is removed from the internal threaded pipe 1. The flexible strip 12 is then pulled after passing around the explosion-proof flexible pipe joint. The operator holds the vertical internal threaded pipe 1 with one hand and holds the hook 13 with the other hand and pulls the flexible strip 12. The above actions are repeated to quickly remove and tighten the explosion-proof flexible pipe joint. The hook 13 allows the tightening tool to be suspended at the operator's waist belt and provides a point of force for the operator to apply force to the flexible strip 12, making it easier for the operator to hold the flexible strip 12.

[0033] In use, the two ends of the malleable metal strip 4 are passed through the two sides of the explosion-proof flexible pipe joint and connected to the internal threaded pipe 1. The second V-shaped clamp 5 is locked with the nut on the explosion-proof flexible pipe joint. The threaded rod 2 is rotated so that the first V-shaped clamp 3 moves closer to the second V-shaped clamp 5. The nut on the explosion-proof flexible pipe joint is locked between the first V-shaped clamp 3 and the second V-shaped clamp 5. The internal threaded pipe 1 is rotated so that the explosion-proof flexible pipe joint rotates under the action of the screwing force and is in a loose state. Then, the movable explosion-proof flexible pipe joint can be rotated further by the flexible strip 12.
