Description

Technical Field

[0001] This utility model relates to the field of fuse technology, specifically to a convenient tool for replacing electrical fuses. Background Technology

[0002] As a component used for circuit protection, the core function of a fuse is to melt and break the circuit when the current exceeds the rated value. It is widely used in electrical equipment to prevent damage to equipment or lines. The fuse element in the fuse is the core component of the fuse, which has a built-in fuse and achieves overload protection through the melting mechanism.

[0003] Currently, some fuses provide a carrier for the fuse element with an internal fuse, allowing it to be installed in various electrical equipment. When the fuse in the fuse element fails, the worker can quickly remove and replace the fuse element by opening the support on the surface of the fuse. However, since the fuse housing is still stably installed inside the electrical equipment, there is still a high risk for workers to handle the fuse element with their bare hands, especially when operating at night or in high-altitude areas, where the risk increases significantly. Wearing insulated gloves reduces the dexterity of the fingers, making the process of removing the fuse element inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a convenient tool for replacing electrical fuses, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient fuse replacement tool, comprising a housing and a support, and further comprising: A positioning assembly, located inside the support, is used to connect the housing and the support. The positioning assembly includes a connector located inside the support, with a filling part and a force-applying part respectively installed at both ends of the connector.

[0006] Preferably, the filling portion includes: The load-bearing component is welded to one end of the connector and moves inside the support. A limiting component is welded to the surface of the load-bearing component and moves through the shell. When the limiting component is connected to the shell, it can serve as a rotation axis of the support. A spring is fixedly connected to the force-bearing component, and one end of the spring is fixed to the inside of the support.

[0007] Preferably, protective components are rotatably connected to both sides of the housing, and the limiting component slides through the protective components.

[0008] Preferably, the surface of the limiting member is provided with a groove, and the inner wall of the protective member is provided with a protrusion, the surface of the protrusion being in contact with the inner wall of the groove.

[0009] Preferably, the force-applying part includes a guide member welded to the other end of the connector, a hollow frame welded to the top of the guide member, and a flipping member rotatably connected inside the hollow frame.

[0010] Preferably, the surface of the flipping component is provided with an extension, which is designed at an angle.

[0011] Preferably, a movable part is welded to the bottom of the guide member, and a sliding groove is formed on the inner wall of the support, with the surface of the movable part slidably connected to the inner wall of the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, this utility model allows for the storage and use of the fuse core body. When the fuse core body is damaged, the worker can flip over the support and then move the connecting part and the filling part through the force application part. After the connection between the limiting part and the shell is released, the worker can remove the support. The support is disconnected from the shell, increasing the safety of subsequent operations. The worker can invert the support, and the fuse core body can fall out of the support. This solves the problem that when the fuse core in some fuses is damaged, the safety of the worker replacing the fuse core by hand is not good, and the process of removing the fuse core is easily affected when the worker is wearing insulating gloves.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-6 As shown, a convenient fuse replacement tool includes a housing 100 and a rotatable support 200 for storing a fuse core 300. A positioning assembly 400 is provided inside the support 200. The positioning assembly 400 includes a connector 410 disposed inside the support 200. The connector 410 moves within the support 200. A filling part 420 and a force-applying part 430 are respectively installed at both ends of the connector 410. The operator can move the connector 410 through the force-applying part 430. At this time, the connector 410 can drive the filling part 420 to move. Under normal use, the filling part 420 is connected to the housing 100 and limits the movement of the support 200.

[0017] The force-applying part 430 includes a guide 431 welded to the other end of the connector 410. A hollow frame 432 is welded to the top of the guide 431. A flipping part 433 is rotatably connected inside the hollow frame 432. The flipping part 433 is in contact with the top of the guide 431. After the operator flips the flipping part 433, the surface of the flipping part 433 contacts one side of the inner wall of the hollow frame 432. At this time, the operator pushes the flipping part 433, which can drive the connector 410 to move through the hollow frame 432 and the guide 431. The surface is provided with an extension, which is designed at an angle. The extension allows the operator to easily rotate and flip the component 433. A movable component 440 is welded to the bottom of the guide component 431. A groove 450 is provided on the inner wall of the support 200. The surface of the movable component 440 is slidably connected to the inner wall of the groove 450. When the operator moves the guide component 431, the movable component 440 moves on the inner wall of the groove 450. The movable component 440 and the groove 450 cooperate to guide the movement of the guide component 431, thereby increasing the stability of the movement of the connecting component 410.

[0018] The filling part 420 includes a force-bearing member 421 welded to one end of the connector 410. A limiting member 422 is welded to one side of the surface of the force-bearing member 421. The limiting member 422 moves through the housing 100. When the support 200 rotates, it rotates around the limiting member 422. A spring 423 is fixedly connected to the other side of the surface of the force-bearing member 421. One end of the spring 423 is fixed to the inside of the support 200. The force-bearing member 421 can move inside the support 200. The elastic force of the spring 423 can push the force-bearing member 421 and the limiting member 422, so that the limiting member 422 can pass through the housing 100.

[0019] Based on the above description, protective members 424 are rotatably connected to both sides of the housing 100. The limiting member 422 slides through the protective member 424. The protective member 424 can protect the end of the limiting member 422 that extends out of the housing 100. The surface of the limiting member 422 is provided with a groove, and the inner wall of the protective member 424 is provided with a protrusion. The surface of the protrusion fits against the inner wall of the groove. By increasing the friction area, the friction force can be increased, reducing the possibility of the limiting member 422 moving accidentally without the influence of external force.

[0020] Working principle: The operator can adjust the support 200 by flipping it. Figure 1 In the state shown, the core body 300 is exposed. Then, the operator pushes the flipping component 433, and the connecting component 410 moves accordingly. The limiting component 422 moves out from inside the protective component 424, releasing the contact between the limiting component 422 and the housing 100. The operator removes the support 200 and inverts it, causing the core body 300 to fall. After replacing the core body 300, the operator puts the support 200 back into the housing 100. At this point, under the force of the spring 423, the limiting component 422 moves outward, passes through the housing 100, and gets stuck in the protective component 424. The support 200 and the housing 100 are connected through the limiting component 422. Finally, the operator pushes the support 200 in the opposite direction, causing the core body 300 to be stored in the housing 100. The flipping component 433 rotates under gravity and fits against the top of the guide component 431 for subsequent use.
