Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically to an interlocking adjustable wrench. Background Technology

[0002] A wrench is a tool used to tighten or loosen threaded connections such as bolts and nuts. It has a wide range of applications in daily life and production. For example, in the maintenance of power plants, it is often necessary to use wrenches to tighten or loosen nuts and bolts of various sizes. Since traditional fixed-size wrenches can only be used for nuts and bolts of specific sizes, their use is very limited. Therefore, adjustable wrenches are increasingly used in engineering projects.

[0003] Adjustable wrenches typically consist of a fixed jaw and a movable jaw. By changing the distance between the movable and fixed jaws, they can accommodate nuts and bolts of different sizes. However, after adjustment, the movable jaw of an adjustable wrench may not make as tight a contact with the nut or bolt as a fixed-size wrench, which can cause slippage during use and make it inconvenient to tighten or loosen rusty nuts. Utility Model Content

[0004] The purpose of this utility model is to provide an interlocking adjustable wrench. This device is equipped with a fixed frame and a screw that cooperate to engage and lock the nuts and other parts to be disassembled, thereby solving the problems mentioned in the background art.

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides a technical solution: an interlocking adjustable wrench, including a fixed frame 1, a first nut 2, a socket 3, a second nut 4, and a screw 5.

[0027] The fixing frame 1 is a hollow rhomboid structure. The lower end of the fixing frame 1 has a notch. A first nut 2 is installed at the lower notch of the fixing frame 1. The first nut 2 is welded and fixed to the fixing frame 1. The fixing frame 1 and the first nut 2 together form the wrench head structure. A handle structure is installed below the wrench head structure. The handle structure and the wrench head structure are assembled to form a complete adjustable wrench. The handle structure includes a sleeve 3, which is a hollow steel pipe structure. A second nut 4 is installed at one end of the sleeve 3. The sleeve 3 and the second nut 4 are welded and fixed. A screw 5 is threadedly connected to the inner wall of the second nut 4. The sleeve 3, the second nut 4 and the screw 5 together form the handle structure. The outer surface of the screw 5 in the handle structure is threadedly connected to the inner wall of the first nut 2 in the wrench head structure.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a rhomboid fixing frame 1 is welded from Mn13 high-manganese steel bars, and the fixing frame 1 is welded to the No. 1 nut 2 to form a wrench head structure. During the welding process, D266 welding rods with a small diameter of 3.0mm-3.5mm are used. A method of low current, high voltage, multiple weld layers, multiple weld passes, and rapid welding is employed. After each layer is welded, the weld is hammered to improve its resistance to hot cracking. After welding, the weld is rapidly cooled to ensure the weld strength. The wrench head structure can be made in different sizes, and together with the handle structure, it can disassemble bolts of different specifications. A 30mm hollow steel pipe sleeve 3 is welded to a 27mm No. 2 nut 4, and a 16mm threaded steel rod is used to make the screw 5. The threaded steel rod 5 has high strength, high tensile strength, and good wear resistance. With advantages such as good anti-loosening effect, the manufactured screw 5 is threadedly connected to the second nut 4, so that the outer surface of the screw 5 wraps around the inner surface of the sleeve 3. The sleeve 3, the second nut 4, and the screw 5 together form the handle structure. The handle structure is connected to the wrench head structure to form a complete interlocking adjustable wrench. When using the wrench to disassemble the bolt, the pointed edge of the inner surface of the diamond-shaped fixing frame 1 is pressed tightly against the diamond edge of the bolt to be disassembled. The sleeve 3 is rotated by hand. The rotation of the sleeve 3 causes the screw 5 to rotate on the inner wall of the first nut 2, so that the screw 5 extends into the interior of the fixing frame 1 until the top of the screw 5 presses tightly against the bolt. With the bolt to be disassembled as the center, the sleeve 3 is rotated, so that the handle structure drives the wrench head structure to rotate, thereby disassembling the abnormal bolts such as corroded or necrotic ones.

[0029] Working principle: When using this interlocking adjustable wrench, the screw 5 in the handle structure is threadedly connected to the first nut 2 in the wrench head structure. The diamond-shaped fixing bracket 1 is used to fit against the diamond-shaped edge of the bolt to be disassembled. The sleeve 3 is rotated by hand. The rotating sleeve 3 drives the screw 5 to extend into the fixing bracket 1, so that the top of the screw 5 is tightly pressed against the surface of the bolt to be disassembled. The screw 5 and the fixing bracket 1 can interlock and lock the bolt to be disassembled. Rotating the sleeve 3 will drive the wrench head structure to rotate through the handle structure, thereby disassembling the bolt. This avoids the adjustable wrench slipping and affecting the bolt disassembly process, increasing the overall practicality.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
