Description

Technical Field

[0001] This utility model relates to the field of tracked vehicle maintenance tools, and in particular to a reinforced hex wrench for disassembling and assembling track plates. Background Technology

[0002] Armored vehicle track plates have rubber-coated track pins press-fitted into their lug holes. End connectors are mounted on these pins for connecting the track plates. A hex bolt in the center prevents the end connector from detaching. Therefore, when disassembling a track plate, the hex bolt must first be removed to detach the end connector. However, due to the harsh working environment of the tracks, factors such as corrosion of the end connector bolts can increase the torque during disassembly, eventually causing the hex wrench to break. This hinders repair work and poses a safety hazard. Therefore, a reinforced hex wrench needs to be designed to ensure smooth disassembly and assembly. Summary of the Invention

[0003] The purpose of this invention is to provide a reinforced hex wrench for disassembling and assembling track plates, solving the problem in existing technology where corrosion and other factors increase the torque during the disassembly of the hex bolts of the track end connector, ultimately leading to the easy breakage of the hex wrench. This invention analyzes the location and cause of the breakage and designs a reinforced hex wrench to ensure smooth repair work. The tool consists of three parts: a socket, a ratchet, and a wrench, enabling the disassembly of the hex bolts of the end connector using this device or with the addition of a lever or other devices.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: A reinforced hex wrench for disassembling and assembling track plates includes a sleeve 3, a ratchet 1, and a wrench body 2. The ratchet 1 has four through holes 1-1 at its upper end, which, when combined with a small pry bar, increase the torque. Several grooves 1-2 are evenly distributed in the middle, which cooperate with the protrusions 2-1 in the wrench body 2. A square connector 1-3 is provided at the lower end, which cooperates with the square hole 3-2 in the sleeve 3.

[0005] The wrench body 2 is fitted onto the middle of the ratchet 1, and the groove 1-2 in the middle of the ratchet 1 is tightly engaged with the protrusion 2-1 in the wrench body 2.

[0006] The lower end of the sleeve 3 is provided with a hexagonal connector 3-1, which cooperates with the internal hexagonal hole on the track pin.

[0007] The beneficial effects of this utility model are as follows: It develops a new type of specialized tool that combines the characteristics of equipment maintenance with the needs of actual combat. This tool is high-strength, small in size, lightweight, easy to operate, portable, and not easily damaged. It is suitable for various vehicle models and has a low cost. It is convenient to use, greatly reducing the difficulty of maintenance. It is highly practical. Attached Figure Description

[0011] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. To make the above-mentioned objects, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] See Figures 1 to 5 As shown, the reinforced hex wrench of this utility model for disassembling and assembling track plates consists of three parts: a socket 3, a ratchet 1, and a wrench body 2. The ratchet 1 has four through holes 1-1 at its upper end, which can be combined with a small pry bar to increase torque; a groove 1-2 in the middle part can cooperate with the protrusion 2-1 in the wrench body 2 to achieve the ratchet wrench effect; and a square connector 1-3 at the lower end can cooperate with the square hole 3-2 in the socket 3.

[0013] The wrench body 2 is fitted onto the middle of the ratchet 1, and the groove 1-2 in the middle of the ratchet 1 is tightly engaged with the protrusion 2-1 in the wrench body 2.

[0014] The lower end of the sleeve 3 is provided with a hexagonal connector 3-1, which cooperates with the internal hexagonal hole on the track pin.

[0015] See Figures 1 to 5As shown, in actual use, the reinforced hexagonal wrench of this utility model for disassembling and assembling track plates combines the hexagonal connector 3-1 at the lower end of the socket 3 with the hexagonal hole on the track pin, and the square connector 1-3 at the lower end of the ratchet 1 with the square hole 3-2 inside the socket 3. The wrench body 2 is fitted into the ratchet 1. By rotating the wrench body 2, the ratchet 1 is rotated, which in turn drives the socket 3, and the socket 3 drives the track pin to rotate. When the disassembly torque of the track pin is large, a lever can be added to the through hole of the wrench body or the ratchet 1 to achieve the effect of quickly disassembling the track pin.

[0016] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made to this utility model should be included within the protection scope of this utility model.
