Lightweight composite material explosion-proof wrench

Abstract

This utility model discloses a lightweight composite explosion-proof wrench, belonging to the field of tool technology. It includes a working part one, a lightweight wrench connecting part, and a working part two. A reinforcing member one is embedded within the working part one, configured to completely enclose it. A reinforcing member two is embedded within the working part two, configured to completely enclose it. Reinforcing plates are embedded on both sides of the lightweight wrench connecting part, configured to completely enclose it. The lightweight wrench connecting part reduces the overall weight while maintaining strength. Embedding reinforcing components within the working parts one and two significantly improves the strength, rigidity, and surface wear resistance of the working parts one and two. Furthermore, since the reinforcing members one, two, and the reinforcing plates are all enclosed on the inside, good insulation is achieved, and no sparks are generated during operation due to friction or collision, resulting in excellent explosion-proof performance.

Description

Technical Field

[0001] This utility model belongs to the field of tool technology, specifically a lightweight composite material explosion-proof wrench. Background Technology

[0002] A wrench is a common installation and disassembly tool. It is a hand tool that uses leverage to tighten or loosen bolts, screws, nuts, and other threaded fasteners. Typically, it has openings or holes at one or both ends of the handle to hold the bolt or nut. When in use, external force is applied to the handle in the direction of thread rotation to tighten the bolt or nut. In current technology, to reduce the cost and weight of wrenches, the production of all-plastic wrenches is increasing. However, all-plastic wrenches have the problem of low strength in the working area, such as the jaws. With use and increased intensity, all-plastic wrenches will wear down or even be damaged. While all-alloy wrenches meet the strength requirements, they are too heavy to carry, are conductive and non-insulating, and can produce sparks when struck. They also lack the inherent safety characteristics of explosion-proof tools. Therefore, a high-strength, lightweight, composite material explosion-proof wrench is needed. Utility Model Content

Reinforcing plates 400 are embedded on both sides of the lightweight wrench connecting part 120 and are configured to completely enclose the lightweight wrench connecting part 120. The outer sides of the reinforcing member 200, the second reinforcing member 300, and the reinforcing plates 400 are all provided with textures to strengthen the connection and increase friction. This embodiment of the lightweight composite reinforced wrench reduces overall weight while maintaining strength through the lightweight wrench connector 120. Reinforcing components are embedded within the working parts 110 and 130, significantly improving their strength, rigidity, and surface wear resistance, allowing the wrench to withstand greater forces and extending its service life. It is more durable than all-plastic wrenches and lighter than all-metal and alloy wrenches, making it convenient to carry and use. Furthermore, the reinforcing components 200, 300, and 400 are all enclosed on the inside, achieving good insulation and preventing sparks from friction and collision during operation, thus providing excellent explosion-proof performance.

[0033] The reinforcing plate 400 is horizontally embedded in the surface of the lightweight wrench connecting part 120. Specifically, the surface of the lightweight wrench connecting part 120 is provided with a groove for accommodating and fixing the reinforcing plate 400. The reinforcing plate 400 is made of alloy sheet, ceramic sheet or other materials with high hardness. The lightweight wrench connecting part 120 is made of all-carbon fiber composite blend polymer material.

The force-bearing surfaces of the reinforcing portion 220 and the reinforcing portion 220 are configured as working surfaces or the outer side of the force-bearing surfaces is wrapped to form a working surface.

[0035] The second reinforcing member 300 includes a second lightweight wrench connecting part 310 and a second reinforcing part 320. The shape of the second reinforcing part 320 is adapted to the shape of the second working part 130. The second lightweight wrench connecting part 310 is configured to extend into the second lightweight wrench connecting part 120. The thickness of the second reinforcing part 320 is greater than 40% of the thickness.

[0036] Lightweight wrench connecting part 1 210 and lightweight wrench connecting part 2 310 are configured to extend into lightweight wrench connecting part 120, thereby avoiding the possibility of breakage between lightweight wrench connecting part 120 and working part 110 and working part 2 130 during operation, and improving overall strength and stress consistency. The reinforcing part 2 320 is annular, and its edge is provided with several corrugated recesses.
