Description

Technical Field

[0001] This utility model relates to the field of fuse technology, and in particular to drop-out high-speed fuses. Background Technology

[0002] A fuse is an electrical device used to protect circuits from overloads and short circuits. It is usually made of a metal wire or other material. When the current exceeds the set rated value, the fuse melts and breaks the circuit, thus preventing damage to the equipment in the circuit or the risk of fire. Fuses are commonly used in household circuits, industrial equipment, and automotive electrical systems.

[0003] At present, fuses are crucial in circuit transmission. Most current fuses are push-up fuses, which require a lot of labor to push and connect, greatly reducing their practicality. To address this issue, we propose a drop-out high-speed fuse. Utility Model Content

[0004] The purpose of this invention is to provide a drop-out high-speed fuse to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drop-out high-speed fuse includes a fuse rod, the outer surface of which is connected to two connecting seats. The outer surfaces of the two connecting seats are respectively threaded to a connecting frame and a retaining plate by two mounting screws. A drop rod is hinged to one side of the connecting frame by a pin. One end of the drop rod is connected to a retaining block, which engages with the retaining plate. A conduction frame is connected to one side of one of the connecting seats, and a conduction block is connected to one side of the conduction frame.

[0007] In a further embodiment, a hanging ring is connected to the outer surface of the drop bar, and the outer surface of the hanging ring is provided with anti-slip texture.

[0008] In a further embodiment, a diversion frame is connected to one side of the connecting frame, and one side of the conductive block is connected to one side of the fuse column.

[0009] In a further embodiment, a set of fusing grooves are formed on the outer surface of the fusing post, and a protective layer is sprayed on the outer surface of the fusing post.

[0010] In a further embodiment, a nameplate is attached to the outer surface of the drop bar, and the outer surface of the nameplate is coated with a galvanized layer.

[0011] In a further embodiment, a fixed rod is connected to one side of the fusible link, and the fusible link is made of ceramic.

[0012] In a further embodiment, a connecting rod is connected to one side of the connecting frame, and the outer surface of the connecting rod is coated with a waterproof layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device can fuse the circuit by means of a fuse rod. It works with a connecting seat, connecting frame and card plate, and a drop bar that is hinged to the connecting frame by a pin and a card block that is locked to the card plate. With the dropping force of the drop bar, it can quickly activate the fuse rod, which reduces the workload of personnel. At the same time, it is simple to operate and low in cost.

[0024] Please see Figure 1-5In this utility model, a drop-out high-speed fuse includes a fuse rod 1. Two connecting seats 2 are connected to the outer surface of the fuse rod 1. Connecting frames 3 and a mounting plate 9 are threaded onto the outer surfaces of the two connecting seats 2 via two mounting screws. A drop rod 5 is hinged to one side of the connecting frame 3 via a pin. A locking block 6 is connected to one end of the drop rod 5 and engages with the mounting plate 9. A conduction frame 7 is connected to one side of one connecting seat 2, and a conduction block 8 is connected to one side of the conduction frame 7. The fuse rod 1 can fuse the circuit. In conjunction with the connecting seats 2, connecting frames 3, and mounting plate 9, and with the drop rod 5 hinged to the connecting frame 3 via a pin, and the locking block 6 engaging with the mounting plate 9, the drop rod 5's falling force enables the fuse rod 1 to operate quickly. This reduces the workload of personnel, is simple to operate, and is inexpensive.

[0025] The outer surface of the drop bar 5 is connected to a lifting ring 10. The outer surface of the lifting ring 10 is provided with anti-slip texture. The lifting ring 10 and anti-slip texture make it easy to carry the equipment. One side of the connecting frame 3 is connected to a diverter frame 11. One side of the conductive block 8 is connected to one side of the fuse column 1. The diverter frame 11 can be used to easily connect the connecting frame 3 to an external conductive component. The outer surface of the fuse column 1 is provided with a set of fuse grooves 12. The outer surface of the fuse column 1 is coated with a protective layer. The fuse grooves 12 can increase the conduction effect of the fuse column 1.

[0026] A nameplate 14 is attached to the outer surface of the drop bar 5. The outer surface of the nameplate 14 is coated with a galvanized layer. The nameplate 14 increases the recognizability of the device. A fixed rod 13 is attached to one side of the fuse rod 1. The fuse rod 1 is made of ceramic. The fixed rod 13 can protect the fuse rod 1. A connecting rod 4 is attached to one side of the connecting frame 3. The outer surface of the connecting rod 4 is coated with a waterproof layer. The connecting rod 4 can extend the length of the conductor.

[0027] The working principle of this utility model is as follows:

[0028] First, the device is installed at the designated location, and the wires that need to be connected are installed with the device. If the device needs to conduct electricity, the drop bar 5 is hinged to the connecting frame 3 through a pin, and the force of the drop bar 5 falling allows the locking block 6 to be locked into the card seat plate 9. At the same time, the fuse column 1 can melt it. In addition, the combination of the above structures enables the device to conduct electrical transmission. The above is the complete usage process of this utility model.
