Technical Field

[0001] The utility model belongs to the technical field of fuse installation, and in particular relates to an auxiliary installation component of a fuse. Background Art

[0002] A fuse is an electrical appliance that uses the heat generated by itself to melt the fuse and disconnect the circuit when the current exceeds the specified value. The fuse is a current protector made based on this principle. 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. Fuses are usually installed at the starting point of the circuit, that is, the location where the power enters the building or equipment. It can be installed in distribution boxes, power switch cabinets or circuit branch boxes.

[0003] However, the above device still has the following problems during implementation:

[0004] According to the prior art, fuses are usually installed in distribution boxes. When installing fuses, because there are many wires in the distribution box and the fuses are fixed by multiple screws, workers need to hold a screwdriver and rotate it in the distribution box for a long time. This may cause the workers to accidentally touch the circuit due to the long installation time, which may cause dangerous situations. Therefore, an auxiliary installation component of the fuse is specially proposed to solve the above problem. Utility Model Content

[0025] Two fixing components 6 for fixing the position of the mounting plate 2, the fixing components 6 being arranged in the inner cavity of the movable groove 4;

[0026] The control component 7 is used to control the fixing component 6 , and the control component 7 is arranged in the inner cavity of the mounting groove 5 .

[0027] refer to Figure 2 The four corners of the rear side of the mounting plate 2 are all provided with docking grooves 8, and the inner cavity of the docking grooves 8 is plugged and connected with docking blocks 9, and the rear side of the docking blocks 9 is fixedly connected to the inner wall of the cabinet 1.

[0028] The above scheme is adopted: by setting the docking groove 8 and the docking block 9, after the installation plate 2 is picked up and contacts the inner wall of the cabinet 1, the docking block 9 will be inserted into the docking groove 8, and the position of the installation plate 2 can be positioned, which facilitates the alignment of the plug-in groove 63 and the plug-in block 62.

[0029] refer to Figure 3 The fixed component 6 includes a movable plate 61, and the top and bottom of the opposite sides of the two movable plates 61 are fixedly connected with plug-in blocks 62. The side of the docking block 9 close to the plug-in block 62 is provided with a plug-in slot 63 used in conjunction with the plug-in block 62. The side of the plug-in block 62 close to the plug-in slot 63 passes through the movable slot 4 and extends to the inner cavity of the plug-in slot 63. The opposite sides of the two movable plates 61 are fixedly connected with springs 64, and the number of springs 64 is four.

[0030] By adopting the above solution: by setting up the fixing component 6, the plug-in block 62 is inserted into the plug-in slot 63, the position of the docking block 9 can be fixed, and the pressure of the spring 64 on the movable plate 61 will prevent the movable plate 61 from detaching due to shaking and causing the plug-in block 62 to detach.

[0031] refer to Figure 3 A moving hole 10 is formed on the opposite side of the two moving grooves 4 , and the moving plate 61 is movably connected to the inner cavity of the moving hole 10 .

[0032] By adopting the above solution, by providing the moving hole 10, when the moving plate 61 moves in the installation groove 5, the moving hole 10 can control the moving position of the moving plate 61, so that the moving plate 61 will not move randomly when moving.

[0033] refer to Figure 3 The control component 7 includes an extrusion hole 71, which is opened on the front side of the movable plate 61. The inner cavity of the extrusion hole 71 is slidably connected with an extrusion block 72, and the rear side of the extrusion block 72 is fixedly connected with a rotating plate 73. The rear side of the rotating plate 73 is rotatably connected to the inner wall of the mounting groove 5 through a rotating shaft.

[0034] The above scheme is adopted: by setting the control component 7, when it is necessary to simultaneously move the two movable plates 61 closer to each other, the rotation of the rotating plate 73 will drive the extrusion block 72 to squeeze the inner wall in the extrusion hole 71, and the extrusion force generated at this time will drive the two movable plates 61 closer to each other.

[0035] refer to Figure 3 A first tooth 11 is fixedly connected to the surface of the rotating plate 73, and second teeth 12 are movably connected to the left and right sides of the inner cavity of the mounting groove 5. The number of the first tooth 11 and the second tooth 12 is multiple, and the first tooth 11 and the second tooth 12 are meshed with each other.

[0036] The above scheme is adopted: by setting the first teeth 11 and the second teeth 12, when the two rotating plates 73 need to be rotated, the second teeth 12 fixed on the surface will drive the meshing first teeth 11 when the pull plate 13 is pulled up, and the second teeth 12 will drive the rotating plate 73 to rotate due to the pulling of the first teeth 11.

[0037] refer to Figure 4 The inner cavity of the mounting groove 5 is movably connected with a pull plate 13 , the top of the pull plate 13 passes through the mounting groove 5 and extends to the outside of the mounting groove 5 , and the second tooth 12 is fixedly connected to the pull plate 13 on one side close to the pull plate 13 .

[0038] The above solution is adopted: by setting the pull plate 13, when it is necessary to drive the rotating plate 73 to rotate, insert a finger into the hole on the front side of the pull plate 13, and then pull the pull plate 13 up in the installation groove 5, so as to easily drive the movable plate 61 to move.

[0039] The working principle of this utility model:

[0040] When in use, when it is necessary to install the fuse device 3 in the cabinet 1, insert a finger into the hole on the front side of the pull plate 13, and then pull the pull plate 13 up in the installation groove 5. When the pull plate 13 rises, the second tooth 12 fixed on the surface will drive the meshing first tooth 11, and the second tooth 12 will be pulled by the first tooth 11 to drive the rotating plate 73 to rotate. The rotation of the rotating plate 73 will drive the extrusion block 72 to squeeze the inner wall in the extrusion hole 71. The extrusion force generated at this time will drive the two moving plates 61 to approach each other, and the moving plate 61 moves the extrusion spring 64 and drives the docking block 9 to disengage from the docking groove 8. Then, pick up the installation plate 2 connected to the fuse device 3 and dock it with the docking block 9. At this time, the docking block 9 will be inserted into the docking groove 8, and then the pull plate 13 can be released. The spring 64 undergoes elastic deformation to drive the moving plate 61 back to its original position. The moving plate 61 moves to drive the plug-in block 62 to be inserted into the plug-in groove 63, and the fuse device 3 can be fixed in position.

[0041] To sum up: the auxiliary installation component of the fuse, through the setting of the fuse device 3, the movable slot 4, the installation slot 5, the fixed component 6 and the control component 7, pick up the installation plate 2 connected to the fuse device 3 and dock it with the docking block 9, then the docking block 9 will be inserted into the docking slot 8, and then the pull plate 13 can be loosened, the spring 64 undergoes elastic deformation to drive the movable plate 61 back to its original position, the movable plate 61 moves to drive the plug-in block 62 to be inserted into the plug-in slot 63, and the fuse device 3 can be fixed in position at this time, which solves the problem that when installing the fuse, there are many wires in the distribution box, and the fuse is fixed by multiple screws, so that the staff needs to hold the screwdriver for a long time to rotate in the distribution box, which is easy to cause the staff to accidentally touch the circuit due to the long installation time.
