Description

Technical Field

[0001] The utility model relates to the field of fuse pressing plates, in particular to a high-strength fuse pressing plate which is not easily deformed. Background Art

[0002] A fuse is an electrical device that is mainly used to break the circuit by melting the fuse through the heat generated by itself when the current exceeds the specified value, thereby protecting the circuit and electrical equipment. The working principle of the fuse is based on the thermal effect of current. When the current in the circuit exceeds the rated value of the fuse, the fuse will melt due to heat, thereby cutting off the circuit.

[0003] After searching, Chinese patent announcement number: CN218471882U discloses a high-strength fuse pressure plate that is not easy to deform. The utility model includes a fuse pressure plate and an assembly hole, and also includes a reinforcement mechanism. The reinforcement mechanism is composed of a layer increase plate, a V-shaped connecting plate, a strip connecting plate, an inner support column and a matching hole. The surface of the fuse pressure plate is provided with an assembly hole for fuse assembly, and a layer increase plate for reinforcement is welded at the V-shaped edge of the bottom surface of the fuse pressure plate outside the assembly hole through a V-shaped connecting plate. The plate body structure of the layer increase plate is the same as the plate body structure of the fuse pressure plate, and a strip connecting plate for connection is welded between the straight edge plate body of the layer increase plate and the straight edge plate body of the fuse pressure plate. A reinforcement mechanism is arranged at the fuse pressure plate outside the assembly hole for hierarchical reinforcement. After the hierarchical reinforcement of the fuse pressure plate by the reinforcement mechanism, the plate body structural strength of the fuse pressure plate is improved, so that when the fuse pressure plate is subjected to a large force, it is not easy to deform and affect the fuse.

[0004] In the above technology, although the structural strength of the fuse pressing plate is improved, so that the fuse pressing plate is not easily deformed and affects the fuse when subjected to a large force, the same structure of the assembly hole and the matching hole allows the fuse to be matched with the build-up plate, which reduces the applicability of the fuse pressing plate. Therefore, a high-strength fuse pressing plate that is not easy to deform is proposed to solve the above problem. Utility Model Content

A pressure plate body 2 is fixedly installed at the front end of the reinforcing plate 1. The reinforcing plate 1 and the front end of the pressure plate body 2 are penetrated with an assembly hole for placing and installing the fuse. A support block 3 is fixedly connected to the inner wall of the front end of the reinforcing plate 1 to support the reinforcing plate 1 and the pressure plate body 2. A slide rail 6 is fixedly connected to the inner wall of the reinforcing plate 1. The pressure plate body 2 is also provided with a slide rail 6. The slide rail 6 is used to stably support the support plate 4 to support The movement of the support plate 4 provides stable guidance, the inner wall of the slide rail 6 is slidably connected with the support plate 4, the support plate 4 is arranged in an M shape, and four groups of support plates 4 are arranged, which increases the stability of the structure. At the same time, the arrangement of four groups of support plates 4 can ensure the uniformity of pressure distribution. A clamping assembly is arranged on the right side of the support plate 4, and the clamping assembly includes a slide rod 51. The slide rod 51 is used to drive the support plate 4 to move. The left side of the slide rod 51 is fixedly connected to the right side of the support plate 4, and the right side outer wall of the slide rod 51 is slidably connected with a slide sleeve 52 to provide space for the movement of the compression spring 53. The right side of the slide sleeve 52 is fixedly connected to the inner wall of the reinforcement plate 1 to make the slide sleeve 52 more stable.

[0032] Reference Figure 2 and Figure 3 The right side of the slide bar 51 is elastically connected to the sliding sleeve 52 by a compression spring 53, and the fuse is adaptively clamped by the elastic force of the compression spring 53. A pull rod 54 is fixedly connected to the right side of the slide bar 51, and the pull rod 54 is used to pull the slide bar 51, so as to adjust the distance of the support plate 4. The right side of the pull rod 54 passes through and is slidably connected to the sliding sleeve 52 and the inner wall of the reinforcing plate 1. The reinforcing plate 1 is slidably connected to a limiting plate 55 near the rear side of the pull rod 54. The front end of the limiting plate 55 is set as an inclined surface, which can slide into the limiting groove 58 to limit the pull rod 54. A pulling block 57 is fixedly connected to the right side of the limiting plate 55, which is used to pull the limiting plate 55 and release the limitation on the pull rod 54. The outer wall of the left side of the pulling block 57 slides on the inner wall of the reinforcing plate 1. The limiting plate 55 and the reinforcing plate 1 are elastically connected by a reset spring 56. The elastic force of the reset spring 56 can drive the limiting plate 55 to quickly limit the pull rod 54, which is convenient for workers to install the fuse.

At this time, pull the pull block 57 to the rear side to make the limit plate 55 slide out from the inner wall of the limit groove 58, releasing the limitation on the pull rod 54. At this time, the elastic force of the compression spring 53 drives the four groups of support plates 4 to clamp the fuse, and the M-shaped structure of the support plate 4 and the support block 3 provide stable support for the reinforcement plate 1 and the pressure plate body 2, while supporting the assembly hole around.
