Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuse technology, and in particular to a mounting base for fuses. Background Technology
[0002] A fuse is an electrical device that breaks the circuit by melting a fusible element when the current exceeds a specified value. After the current exceeds the specified value for a period of time, the fusible element melts due to the heat generated by the fuse itself, thereby breaking the circuit. Fuses are widely used in high and low voltage power distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, and are one of the most commonly used protective devices. Traditional fuse mounting bases have some drawbacks. Fuse bases typically use screws to install fuses. When the fuse needs to be disassembled and inspected periodically, the screws need to be tightened repeatedly, which can easily cause the screw threads to fail, making it inconvenient to repair and maintain the fuse. Utility Model Content
[0003] The main objective of this invention is to provide a mounting base for fuses, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mounting base for a fuse includes a support base and a fuse body. An installation auxiliary mechanism is provided at the upper end of the support base. The installation auxiliary mechanism includes a fixing frame placed on the upper end of the support base. A guide groove is provided at the front end of the fixing frame. A support frame is fixedly connected to the inner wall of the fixing frame. A limiting rod is fixedly connected to the inner side of the support frame. A spring is sleeved on the outer side of the limiting rod near the support frame. A sliding ring is slidably connected to the outer side of the limiting rod near the spring. A pin is fixedly connected to the outer side of the sliding ring. A sliding block is slidably connected to the inner side of the guide groove. A connecting block is fixedly connected to the front end of the sliding block.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] like Figure 1-4As shown, a mounting base for a fuse includes a support base 1 and a fuse body 2. An installation auxiliary mechanism 4 is provided at the upper end of the support base 1. The installation auxiliary mechanism 4 includes a fixing frame 41 placed on the upper end of the support base 1. A guide groove 42 is provided at the front end of the fixing frame 41. A support frame 43 is fixedly connected to the inner wall of the fixing frame 41. A limiting rod 44 is fixedly connected to the inner side of the support frame 43. A spring 45 is sleeved on the outer side of the limiting rod 44 near the support frame 43. A sliding ring 46 is slidably connected to the outer side of the limiting rod 44 near the spring 45. A pin 48 is fixedly connected to the outer side of the sliding ring 46. A sliding block 49 is slidably connected to the inner side of the guide groove 42. A connecting block 410 is fixedly connected to the front end of the sliding block 49. A screw 411 is threadedly connected to the inside of the connecting block 410.
[0015] In this embodiment, a limiting frame 412 is fixedly connected to the lower side of the front end of the fixing frame 41 near the guide groove 42. A threaded rod 413 is threadedly connected to the inner side of the limiting frame 412. A stop plate 47 is fixedly connected to one end of the limiting rod 44. One end of the spring 45 is fixedly connected to one end of the support frame 43, and the other end of the spring 45 is fixedly connected to one end of the sliding ring 46. The stop plate 47 is located inside the pin 48. The pin 48 passes through the interior of the fixing frame 41 and is slidably connected to the fixing frame 41. The pin 48 extends into the interior of the fuse body 2 and is slidably connected to the fuse body 2. The rear end of the sliding block 49 is fixedly connected to the front end of the pin 48. A screw 411 passes through the interior of the fixing frame 41 and is threadedly connected to the fixing frame 41. The threaded rod 413 extends into the interior of the support base 1 and is threadedly connected to the support base 1. There are two sets of installation auxiliary mechanisms 4.
[0016] Specifically, when the fuse body 2 needs to be disassembled and inspected periodically, first unscrew the screw 411, then pull the connecting block 410, which causes the connecting block 410 to slide the sliding block 49 inside the guide groove 42, and the sliding block 49 to move the pin 48, which in turn causes the pin 48 to slide the sliding ring 46 along the limiting rod 44, and the sliding ring 46 to compress the spring 45, thereby causing the pin 48 to disengage from the fuse body 2. At this time, the fuse body 2 can be removed from the support base 1 for inspection. By pulling the connecting block 410, the sliding block 49 moves the pin 48, and the pin 48 moves the sliding ring 46 along the limiting rod 44, which in turn causes the sliding ring 46 to compress the spring 45, thus moving the pin 48. This facilitates the disassembly of the fuse body 2 and avoids the need to repeatedly unscrew the threaded rod 413.
[0017] In this embodiment, the fuse body 2 is placed at the upper end of the support base 1. The fuse body 2 is installed at the upper end of the support base 1 through the installation auxiliary mechanism 4. The upper end of the support base 1 is provided with four sets of mounting holes 3 on the side close to the fuse body 2.
[0018] Specifically, the support base 1 is placed inside the designated equipment, and the bolts are inserted into the mounting holes 3 and screwed into the designated equipment to fix the support base 1 on the designated equipment. Then, the fuse body 2 is placed on the support base 1, and the installation auxiliary mechanism 4 is placed on the support base 1. Then, the pin 48 is inserted into the fuse body 2, and the threaded rod 413 is screwed into the inside of the support base 1 to install the fuse body 2 at the upper end of the support base 1.
[0019] Working principle: In use, first place the support base 1 into the designated equipment, insert the bolts into the mounting holes 3, and tighten the bolts into the designated equipment to fix the support base 1 onto the designated equipment. Then, place the fuse body 2 onto the support base 1 and the installation auxiliary mechanism 4 onto the support base 1. Next, insert the pin 48 into the fuse body 2 and tighten the threaded rod 413 into the interior of the support base 1 to install the fuse body 2 at the upper end of the support base 1. If the fuse body 2 needs to be disassembled and inspected periodically, first unscrew the screw 411, and then pull the connecting block 410. This will cause the connecting block 410 to drive the sliding block 49 to slide inside the guide groove 42, and the sliding block 49 will drive the pin. The pin 48 moves, causing the sliding ring 46 to slide along the limiting rod 44, and the sliding ring 46 to compress the spring 45, thereby causing the pin 48 to disengage from the fuse body 2. At this point, the fuse body 2 can be removed from the support base 1 for maintenance. By pulling the connecting block 410, the sliding block 49 moves the pin 48, and the pin 48 moves the sliding ring 46 along the limiting rod 44, thereby causing the sliding ring 46 to compress the spring 45, which in turn moves the pin 48. This facilitates the disengagement of the pin 48 from the fuse body 2, thus avoiding the need to repeatedly unscrew the threaded rod 413.
