Description

Technical Field

[0001] The utility model relates to the technical field of fuse installation, in particular to an anti-stuck fuse installation structure. Background Art

[0002] A fuse is an electrical device that uses the heat generated by itself to melt the fuse and disconnect the circuit when the current exceeds the specified value. A fuse is a current protector made based on the principle that after the current exceeds the specified value for a period of time, the heat generated by itself will melt the fuse and disconnect the circuit. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short circuit and overcurrent protector, it is one of the most commonly used protection devices. Among them, closed tube fuses are generally used with a holder. After the fuse is blown, the fuse can be quickly replaced. However, due to the high temperature generated when the fuse takes effect, the holder and the fuse are too hot to be touched directly. At the same time, because most fuses are installed in a small space, it is very inconvenient to take them out directly and they are easy to get stuck. Therefore, a device is needed to quickly take out the fuse that is still at a high temperature without waiting for the fuse to cool down before taking it out.

[0003] After searching, the Chinese patent publication number CN213042864U discloses a fuse mounting structure, including a mounting seat and a fuse body, a connecting plate is provided on the rear side of the mounting seat, connecting holes are provided at the corner points of the connecting plate, a mounting groove is provided on the front side of the mounting seat, and first through holes are provided on the left and right side walls of the mounting groove; a positioning frame is movably mounted on the mounting seat, and clamping mechanisms are provided on the left and right side walls of the positioning frame.

[0004] Aiming at the problem that the fuse is positioned by screw rods on both sides in the above technology, the device requires a large installation space and the operation of rotating the screw rods on both sides is relatively complicated; therefore, an anti-stuck fuse installation structure is proposed.

The lower end of the limit plate 16 is stuck between the two arc-shaped bosses above the lower lifting sleeve 18. When the fuse component 3 needs to be removed, the lifting sleeve 14 on the lifting side plate 4 is pressed downward to move downward. The limit plate 16 can prevent the upper lifting sleeve 14 from rotating, and the lower lifting sleeve 18 is rotated by squeezing each other through the arc-shaped bosses. When the lifting platform 2 is lifted again, the limit plate 16 falls into the lifting groove 19. At this time, the lower lifting sleeve 18 lifts the upper lifting sleeve 14 and the lifting platform 2, and the fuse component 3 is half exposed from the seat, so that the staff can quickly remove it to prevent it from being stuck in a small space. At the same time, it can be taken out by vertical pressing, which reduces the space occupied horizontally.
