Fuse auxiliary device capable of automatically replacing broken fuse

Abstract

The invention relates to the technical field of fuse devices, and discloses a fuse auxiliary device capable of automatically replacing a broken fuse. The device comprises a movable plate, a rotating shaft is movably connected to the top end of the movable plate, a movable belt penetrates through the side walls of the rotating shaft, and a connecting ring is arranged on the side wall of the movableplate; a movable block is slidably connected to the side wall of the connecting ring, a sliding piece penetrates through the side wall of the inner ring of the connecting ring, and a pulling belt ismovably connected to the bottom end of the connecting ring. Along with push-out of the sliding pieces, the inner side walls of the connecting rings lose supporting force and can be gathered together again under the pulling force of the pulling belts at the bottoms of the connecting rings, the outer side walls of the connecting rings can drive the upper ends of the side walls of the movable platesto be combined again, and the included angle between the inner side walls of the movable plates is gradually decreased along with the state that the upper ends of the side walls of the movable platesslowly get close; the side wall of the sliding piece slides outwards along the side wall of the movable plate to the rotating shaft at the top end and is instantly clamped by the clamping teeth in therotating shaft.

Description

technical field [0001] The invention relates to the technical field of fuse devices, in particular to an auxiliary fuse device that can automatically replace a fuse after it breaks. Background technique [0002] In circuit equipment such as relays and storage equipment such as safes, in order to ensure that the equipment will not be dangerous and protect the equipment from damage, safety devices will be installed in these devices. Due to the advantages of reducing losses, the safety device is widely used in people In various fields of daily life, for example, there are circuit safety devices such as various fuses and circuit breakers on automobiles, and overload safety devices are also arranged on household plug boards. [0003] Common fuses and fuses in insurance devices, among them, insurance is widely used due to its advantages of sensitive detection and easy replacement, but the fuse itself is also a consumable with a certain life span.

Problems solved by technology

[0003] Common fuses and fuses in insurance devices, among them, insurance is widely used due to its advantages of sensitive detection and easy replacement, but the fuse itself is also a consumable with a certain life span. After normal damage during use, it needs to be replaced in time. Replacement, but the current fuse cannot be replaced automatically in the current fuse, it needs to be manually inspected regularly, and the fuse must be replaced after it is found to be invalid, which has a certain impact on the normal operation of the fuse
