Description

Technical Field

[0001] The invention belongs to the technical field of comparison plates, and more specifically to a comparison plate for installing a fuse box. Background Art

[0002] When installing the fuse in the electrical box, the fuse is usually installed by direct pressing. Normal pressing will cause the fuse to be pressed off-center or installed incorrectly, and re-installing will consume a lot of man-hours. The comparison plate can be used to assist in fixing the fuse installation, making the installation of the fuse more convenient.

[0003] Comparative document CN203339535U discloses a voltage transformer fuse installation tool. When in use, the ferrule is fixed to the side of the primary side fuse of the voltage transformer away from the top cover, one end of the first connecting rod is fixed to the first arc-shaped clamping plate through the first screw hole, and one end of the second connecting rod is fixed to the second arc-shaped plate through the second screw hole. Then, the connecting plate is placed on the outside of the top cover, and the other end of the first connecting rod is passed through the first through hole on the connecting plate. Then, the first nut is screwed onto the first connecting rod, and the other end of the second connecting rod is passed through the second through hole on the connecting plate. Finally, the second nut is caught up with the second connection well. Compared with the present invention, it does not have a fuse plug comparison structure, which makes the fuse plug prone to misalignment during installation.

The traditional fuse box installation operation usually adopts a direct pressing method to install the fuse. It does not have a comparison auxiliary structure. Normal pressing will cause the fuse to be pressed off-center and installed incorrectly, and reworking will consume a lot of work; secondly, the traditional fuse box installation comparison plate does not have an auxiliary installation structure. The fuse box has several groups of fuse sockets of the same size. Directly inserting the fuse plug through the traditional comparison plate will cause it to be misaligned; secondly, the traditional fuse box installation comparison plate does not have an elastic fixing structure, which makes it easy to loosen and dislocate after repeated installation and use, bringing certain adverse effects to the user. Summary of the invention

[0017] Beneficial effects of the present invention:

[0018] 1. By setting a comparison plate, when the user needs to perform a safety installation operation on the socket of the fuse box, by opening the first connection groove, the second connection groove, the third connection groove and the fourth connection groove corresponding to the position and size of the socket of the fuse box on the comparison plate, when installing the fuse plug, align the comparison plate with the upper part of the fuse box, hold the fixed vertical rod to press the comparison plate downward, so that the elastic clamp at the bottom of the comparison plate is stuck on the inner side of the fuse box, fix the comparison plate on the upper part of the fuse box, and align the socket of the fuse box with the first connection groove, the second connection groove, the third connection groove and the fourth connection groove on the comparison plate. According to the positions of the four groups of connection slots, select the insurance plugs of corresponding sizes and insert them into the corresponding connection slots to complete the insurance installation operation of the insurance box. By pulling up the fixed vertical rod, the comparison plate is separated from the insurance box, so that the comparison plate can be used repeatedly. Through the setting of the comparison plate, when installing the insurance, the insurance plug can be pressed along the connection slot on the comparison plate to ensure that the insurance plug is vertically inserted into the socket of the insurance box, so that it has a comparison auxiliary structure to avoid the insurance from being misplaced or pressed during the installation process, and effectively improve the insurance installation effect and efficiency.

[0019] 2. By setting a color comparison ring, according to the number of sockets in the fuse box, apply the color comparison ring on the outside of the third connecting slots of a larger number and the same size, so that the color of the color comparison ring is consistent with the color of the corresponding fuse plug. When the user installs the fuse plugs in several groups of third connecting slots, the color of the color comparison ring on the third connecting slot can be used to determine the position where the fuse plug should be inserted, thereby avoiding the misalignment of the third connecting slot during the insertion of the fuse plug. The setting of the color comparison ring makes the comparison board have an auxiliary installation structure, which effectively avoids the misalignment of the fuse plug.

[0020] 3. By setting up an elastic clip, when the user installs the comparison plate, the user can use the elastic clip to clamp the comparison plate on the fuse box. The arc structure on the side of the arc-shaped clamping block on the elastic clip can reduce the resistance when the elastic clip is inserted into the fuse box. When the elastic clip is inserted into the inner side of the fuse box, the elastic clamping cap is used in conjunction with the spring pin and the telescopic inner rod to make the arc-shaped clamping block close to the inner side of the fuse box, so that the comparison plate has an elastic fixing structure, thereby effectively avoiding the comparison plate from loosening after repeated installation and extending its service life.
