Description

Technical Field

[0001] This utility model relates to the field of combination wrench technology, specifically a multi-functional insulated combination wrench. Background Technology

[0002] Wrenches are widely used in the installation, inspection, and maintenance of power system equipment, as well as in industrial settings where there is a risk of electric shock or an anti-static environment is required. Their insulation properties provide reliable protection against electric shock for operators. Furthermore, this wrench features a modular design, allowing for flexible assembly or replacement of different sizes and types of wrench heads to meet specific needs, achieving multi-purpose functionality.

[0003] The above-mentioned wrenches have the following problems during use: one end of the wrench is often fixed or assembled with a handle, and workers can turn the screw by rotating the handle. Due to the limitation of the turning direction, the handle is usually perpendicular to the wrench body, and the whole is T-shaped or L-shaped. This shape takes up a lot of space. When using an assembled structure, the handle is separated from the body. This approach also requires space to store the handle. Both of the above structures will increase the space occupied by the tool and make it difficult to carry. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional insulated combination wrench to solve the problem mentioned in the background art that the handle of the wrench occupies more space and is not easy to carry.

[0006] Preferably, a square connecting block is fixedly connected to the upper end of the universal joint, and a connecting groove is provided at the lower end of the surface of the universal joint and the sleeve, and the shape of the connecting groove corresponds to the shape of the square connecting block.

[0007] Preferably, a return spring is fixedly connected to the surface of the universal joint.

[0008] Preferably, the surface of the fixing base is provided with a through hole, and a rotating handle is slidably connected in the through hole.

[0009] Preferably, the limiting plate has an arc-shaped groove on the side away from the limiting spring, and the shape and size of the arc-shaped groove correspond to the annular groove.

[0010] Preferably, the storage groove extends to the lower surface of the insulating rod, and the size of the storage groove corresponds to the rotating handle.

[0011] Preferably, the finger grooves and protrusions are provided in two sets and are symmetrically distributed on the inner surface of the storage groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This multi-functional insulated combination wrench features a rotating base that allows the rotating column and fixed base to rotate simultaneously, driving the rotating handle to rotate. A storage slot and protrusion allow the rotating handle to be placed inside the storage slot, thus facilitating its storage, reducing its footprint, and making it easy to carry.

[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] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A multi-functional insulated combination wrench includes an insulating rod 1, which utilizes its insulation properties to tighten and install loose or detached insulator screws on 10 kV and below lines without interrupting power. A connecting seat 2 is fixedly connected to the upper end of the insulating rod 1. A universal joint 3 is movably connected to the upper end of the connecting seat 2. A sleeve 4 is movably connected to the upper end of the universal joint 3. The connecting seat 2 can be connected to the universal joint 3 or directly to the sleeve 4. Various types of sleeves 4 can be used to adapt to different application scenarios. A rotating seat 5 is fixedly connected to the lower end of the insulating rod 1. A rotating column 6 is rotatably connected to the lower end of the rotating seat 5. A fixed seat 7 is fixedly connected to the lower end of the rotating column 6. A limit groove 8 is formed inside the fixed seat 7, and a limit spring 9 is fixedly connected inside the limit groove 8. One end of the limiting spring 9 is fixedly connected to the limiting plate 10, and the end of the limiting plate 10 away from the limiting spring 9 is slidably connected to the rotating handle 11. The rotating handle 11 has a circular groove 12 in the middle, and the two ends of the rotating handle 11 are fixedly connected to the limiting posts 13. The limiting posts 13 prevent the rotating handle 11 from sliding out of the fixed seat 7. The lower end of the surface of the insulating rod 1 has a storage groove 14 that extends to the lower surface of the insulating rod 1, making the lower surface of the insulating rod 1 open. The upper end of the storage groove 14 has a finger groove 15, and the inner surface of the storage groove 14 near the finger groove 15 is fixedly connected to a protrusion 16. The above structures together achieve the effect of storing the rotating handle 11 and limiting the rotating handle 11 to prevent it from sliding during use.

[0024] Furthermore, a square connecting block is fixedly connected to the upper end of the connecting seat 2 and the universal joint 3. A connecting groove is opened at the lower end of the surface of the universal joint 3 and the sleeve 4, and the shape of the connecting groove corresponds to the shape of the square connecting block. The above structure allows the device to connect various sleeves 4, enhancing the applicability of the device.

[0025] Furthermore, a return spring is fixedly connected to the surface of the universal joint 3, and the above structure allows the universal joint 3 to return to its original position after rotation.

[0026] Furthermore, the surface of the fixed base 7 is provided with a through hole, and a rotating handle 11 is slidably connected in the through hole. The limiting groove 8 is set in the center of the through hole of the fixed base 7, and two sets of limiting grooves 8 are provided, symmetrically distributed on both sides of the through hole. The above structure allows the rotating handle 11 to slide in the through hole of the fixed base 7. When the rotating handle 11 slides to the center of the fixed base 7, it can be limited to prevent displacement during use.

[0027] Furthermore, the limiting plate 10 has an arc-shaped groove on the side away from the limiting spring 9, and the shape and size of the arc-shaped groove correspond to the annular groove 12. The limiting plate 10 has two sets symmetrically distributed on both sides of the rotating handle 11. The above structure allows the limiting plate 10 to pop out by the action of the limiting spring 9 when the annular groove 12 moves to the center position of the fixed base 7, and to be stuck in the position of the annular groove 12, thereby limiting the displacement of the rotating handle 11 and affecting its use.

[0028] Furthermore, the storage groove 14 extends to the lower surface of the insulating rod 1, and the size of the storage groove 14 corresponds to the rotating handle 11. The above structure allows the rotating handle 11 to be stored inside the storage groove 14.

[0029] Furthermore, the finger groove 15 and the protrusion 16 are each provided in two sets and are symmetrically distributed on the inner surface of the storage groove 14. The above structure allows the rotating handle 11 to be stored by limiting the movement of the rotating handle 11 through the protrusion 16, preventing the rotating handle 11 from sliding out of the storage groove 14. The rotating handle 11 can be pulled out of the storage groove 14 for use through the finger groove 15.

[0030] Working principle: When using the device, the operator selects a different type of sleeve 4 according to the type of screw and places it on the universal joint 3. The universal joint 3 can be rotated to easily align the sleeve 4 with the screw, or the sleeve 4 can be directly placed on the connecting seat 2. The operator pulls the rotating handle 11 out of the storage slot 14 through the finger groove 15, rotates the rotating column 6 to make the rotating handle 11 perpendicular to the insulating rod 1, and drags the rotating handle 11 to slide inside the fixed seat 7, aligning the annular groove 12 on the rotating handle 11 with the position of the limiting plate 10. Since the diameter of the annular groove 12 is smaller than that of the rotating handle 11, the limiting plate 10 will be under the elastic action of the limiting spring 9. When the device pops out, the two side limiting plates 10 will lock in the position of the annular groove 12 to limit the rotation handle 11, so as to prevent the rotation handle 11 from changing position during the operation of the rotating device and affecting the efficiency of use. After use, the worker drags the rotation handle 11. Since the edges of the annular groove 12 and the limiting plate 10 are curved, the limiting plate 10 will slide out from the inside of the annular groove 12 under the action of force. Then the worker continues to drag the rotation handle 11, rotates the rotating column 6 to align the rotation handle 11 with the position of the storage groove 14, and presses the rotation handle 11 to slide into the storage groove 14 between the two sets of protrusions 16, thus completing the storage of the rotation handle 11.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
