Description

Technical Field

[0001] The present application relates to a multi-functional wrench tool, belonging to the technical field of pipeline tools. Background Art

[0002] With the popularization of urban gas and the large-scale implementation of the "coal-to-gas" project across the country, the number of gas users has increased significantly. In the inspection and maintenance of natural gas equipment, there are a large number of hexagon socket head cap screws and hexagon bolts in the pressure regulator, and two types of wrench tools need to be frequently replaced, reducing the work efficiency of maintenance personnel. Generally, the wrenches in the prior art can only replace hexagon socket head cap screws or hexagon bolts. For example, a Chinese patent with the publication number CN215240516U mentions a multi-functional wrench tool. By fixedly connecting a rectangular substrate at the end of the handle, a first cavity is opened on the substrate, and a second cavity communicating with the first cavity is also opened on the handle. Two parallel first fixing arms are fixed on the substrate, and a second fixing arm perpendicular to the first fixing arms is provided. Through the adjustment between the two fixing arms, workpieces of various sizes can be replaced, but workpieces of two different types cannot be replaced simultaneously. Therefore, a new wrench tool has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0003] According to one aspect of the present application, a wrench tool that can operate hexagon socket head cap screws and hexagon bolts simultaneously is provided.

[0004] The present application provides a multi-functional wrench tool, including:

[0005] A hexagon socket wrench, arranged in an L shape, for operating hexagon socket head cap screws;

[0006] An external hexagon component, a telescopic component installed on the hexagon socket wrench, for operating hexagon bolts;

[0007] A fastening area is formed between the external hexagon component and the hexagon socket wrench, and the fastening area is used to place hexagon bolts.

[0008] Optionally, the hexagon socket wrench is composed of a first operating end and a second operating end, and the first operating end and the second operating end are integrally formed and connected;

[0009] The interiors of the first operating end and the second operating end are of a hollow structure, and the cross-section of the hollow part is hexagonal.

[0010] Optionally, the external hexagon component is installed on the second operating end;

[0011] The area enclosed by the first operating end, the second operating end, and the external hexagon component is the fastening area.

[0012] Optionally, the external hexagonal component includes a fixing member, a telescopic member, and a rotating member. The fixing member is sleeved outside the telescopic member, and one side of the telescopic member away from the first operating end is fixedly connected to the rotating member;

[0013] The fixing member is fixedly connected to the second operating end.

[0014] Optionally, internal threads are provided inside the fixing member, external threads are provided on the outer side of the telescopic member, and the fixing member is threadedly connected to the telescopic member.

[0015] Optionally, the axial center height of the telescopic member is adapted to the height of the first operating end.

[0016] The beneficial effects that can be produced by this application include:

[0017] 1) The internal hexagonal wrench provided by this application is set to be L-shaped, and the inner parts at both ends of the L-shape are set to be internal hexagonal shapes for operating the internal hexagonal wrench. By inserting the hexagonal bolt into both ends of the internal hexagonal wrench and then twisting the wrench, the disassembly and tightening operations of the internal hexagonal bolt can be completed;

[0018] 2) The external hexagonal component provided by this application is arranged inside the bending surface of the L-shaped bending surface of the internal hexagonal wrench, and is fixedly connected to the second operating end of the internal hexagonal wrench through the fixing member. By rotating the rotating member, the telescopic member can move inside the fixing member, increasing or decreasing the area of the fastening area. The placement area of the external hexagonal bolt is the fastening area. When the external hexagonal bolt needs to be disassembled or tightened, it is placed in the fastening area, and then the telescopic member is rotated by the rotating member to clamp the external hexagonal bolt by the telescopic member and the first operating end (i.e., the area of the fastening area is reduced). Finally, the entire wrench tool is rotated to perform the disassembly and tightening operations of the external hexagonal bolt.

[0019] 3) This application can complete the disassembly and tightening operations of internal hexagon bolts and external hexagon bolts without replacing the equipment. Description of the Drawings

[0023] The present application will be described in detail below in conjunction with embodiments, but the present application is not limited to these embodiments.

[0024] Please refer to Figure 1 As shown, the present application provides a multi-functional wrench tool, including:

[0025] An internal hexagon wrench 1, set in an L shape, for operating on internal hexagon bolts;

[0026] The internal hexagon wrench 1 is composed of a first operating end 4 and a second operating end 5, and the first operating end 4 and the second operating end 5 are integrally formed and connected;

[0027] The interiors of the first operating end 4 and the second operating end 5 are of a hollow structure, and the cross-section of the hollow part is hexagonal.

[0028] It should be noted that when performing the tightening or disassembly operation of an internal hexagon bolt, insert the internal hexagon bolt into the hollow area at both ends of the first operating end 4 or the second operating end 5, so that the hollow area with a hexagonal cross-section catches the nut of the hexagon bolt, and then rotate the entire wrench to complete the disassembly or tightening operation. In this embodiment, the ends of the first operating end 4 and the second operating end 5 that are not in a connected relationship are the operating ends of the internal hexagon bolt, that is, the ends where the disassembly or tightening operation can be performed.

[0030] A fastening area 3 is formed between the external hexagon assembly 2 and the internal hexagon wrench 1. The fastening area 3 is used to place the external hexagon bolt. The external hexagon bolt placed in the fastening area 3 forms a clamping tendency through the combination of the hexagon assembly 2 and a plane on the first operating end 4 of the internal hexagon wrench 1, so that the external hexagon bolt is clamped inside the fastening area 3. After clamping, rotate the entire wrench to complete the disassembly and tightening operations of the external hexagon bolt.

[0031] The external hexagon assembly 2 is installed on the second operating end 5, and the first operating end and the external hexagon assembly 2 form the fastening area 3;

[0032] The area enclosed by the first operating end 4, the second operating end 5 and the external hexagon assembly 2 is the fastening area 3.

[0033] The external hexagon assembly 2 includes a fixing member 6, a telescopic member 7 and a rotating member 8. The fixing member 6 is sleeved outside the telescopic member 7, and one side of the telescopic member 7 away from the first operating end 4 is fixedly connected to the rotating member 8;

[0034] The fixing member 6 is fixedly connected to the second operating end 5.

[0035] The interior of the fixing member 6 is provided with internal threads, and the outer side of the telescopic member 7 is provided with external threads. The fixing member 6 is threadedly connected to the telescopic member 7.

[0036] The axial center height of the telescopic member 7 is adapted to the height of the first operating end 4.
