Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a circuit breaker that can be quickly disassembled and installed. Background Technology

[0002] A circuit breaker is a device used for circuit protection and control. It can quickly interrupt current in abnormal situations, thereby preventing damage caused by circuit overloads, short circuits, and other faults. It can be operated manually or automatically detect abnormal current and disconnect power, ensuring the safety of electrical equipment and personnel. Circuit breakers are widely used in homes, industrial, and commercial buildings and are an indispensable and important component of modern electrical systems.

[0003] Existing circuit breakers are typically fixed to the mounting plate with multiple bolts, which requires tools to tighten these bolts during installation and removal. This makes installation and removal inconvenient and affects long-term maintenance, repair, and replacement, resulting in poor usability. To address this, we propose a circuit breaker that can be quickly installed and removed. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit breaker that can be quickly installed and disassembled, so as to solve the problem mentioned in the background art that the installation and disassembly of the circuit breaker is inconvenient due to the need to tighten multiple screws.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit breaker that can be quickly disassembled and assembled, comprising a mounting rail, wherein a snap-fit ​​groove is machined on the side wall of the mounting rail, a snap-fit ​​strip is fixedly connected to the side wall of the mounting rail, a body is fitted to the side wall of the mounting rail, a snap-fit ​​block is fixedly connected to the rear side of the body, an insertion groove is machined on the top of the snap-fit ​​block, a snap-fit ​​component is snap-fitted to the side wall of the mounting rail, an insertion strip that fits into the insertion groove is fixedly connected to the left side wall of the snap-fit ​​component, a locking piece is fixedly connected to the right side wall of the snap-fit ​​component, and a locking knob is provided on the side wall of the locking piece.

[0006] Preferably, a fastener is fixedly connected to the front side wall of the snap-fit ​​component, and the fastener is fitted to the side wall of the body.

[0007] Preferably, the snap-fit ​​component has a sliding member inside, and the side wall of the sliding member is fitted with a mesh.

[0008] Preferably, the side wall of the mesh is fixedly connected to a connecting block that cooperates with the snap-fit ​​member, and the top of the snap-fit ​​member is provided with a locking bolt.

[0009] Preferably, an axial flow fan is provided inside the sliding member, the mesh is fitted to the right side of the axial flow fan, and a sliding strip is fixed to the outer wall of the sliding member.

[0010] Preferably, the locking piece is fitted to the front side of the mounting track, and the snap-fit ​​block is fitted to both sides of the mounting track.

[0011] Preferably, the snap-fit ​​component is slidably fitted onto the top of the snap-fit ​​groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a snap-fit ​​component on the installation rail that matches the snap-fit ​​groove, allows the snap-fit ​​component to be pushed so that the insertion strip engages with the insertion groove of the snap-fit ​​block when the snap-fit ​​block is engaged with the snap-fit ​​strip and the main body is placed on the installation rail. Then, tightening the locking knob can achieve quick snap-fit ​​of the circuit breaker, thereby enabling quick assembly and disassembly of the circuit breaker. This facilitates the disassembly, inspection, maintenance and replacement of the circuit breaker, eliminating the trouble of using tools to tighten multiple bolts and saving manpower.

[0014] 2. After the circuit breaker is installed, the sliding member can be slid outward in conjunction with the fixed member. At this time, the sliding member is engaged with the front side wall of the circuit breaker. Then, tighten the locking bolt to lock the sliding member. Next, turn on the axial fan so that the axial fan is aimed at the front side wall of the circuit breaker, thereby realizing the air blowing and cooling of the circuit breaker, improving the heat dissipation effect of the circuit breaker, and reducing the amount of dust in the air falling on the front side wall of the circuit breaker.

[0021] Example

[0022] Please see Figures 1-4 The diagram shows a quick-release circuit breaker, including a mounting rail 100, which can be nailed to a wall. The mounting rail 100 has a snap-fit ​​groove 110 on its side wall and a snap-fit ​​strip 111 tightly welded to its side wall. A snap-fit ​​block 121 has a groove on its side wall that mates with the snap-fit ​​strip 111. A body 120 fits into the side wall of the mounting rail 100; the body 120 is a common circuit breaker. The snap-fit ​​block 121 is bolted to the rear of the body 120. An insertion groove 122 is machined on the top of the snap-fit ​​block 121. A snap-fit ​​component 130 is snap-fitted into the side wall of the mounting rail 100. An insertion strip 131 that mates with the insertion groove 122 is bolted to the left side wall of the snap-fit ​​component 130. A locking piece 132 is bolted to the right side wall of the snap-fit ​​component 130, and a locking knob 133 is provided on the side wall of the locking piece 132.

[0023] Specifically, the front side wall of the snap-fit ​​130 is fixed with a fastener 140 by bolts, and the fastener 140 is fitted to the side wall of the body 120.

[0024] Furthermore, the snap-fit ​​component 130 has a sliding component 150 inside, and the side wall of the sliding component 150 is fitted with a mesh 151, which is a common stainless steel dust filter.

[0025] Furthermore, the side wall of the mesh 151 is bolted with a connecting block 152 that mates with the snap-fit ​​member 130, and the top of the snap-fit ​​member 130 is provided with a locking bolt 141.

[0026] Furthermore, an axial fan 153 is installed inside the slider 150. The axial fan 153 is a common small model on the market. It is electrically connected to a common push-button switch located on the side wall of the slider 150. The mesh 151 is fitted to the right side of the axial fan 153. A sliding strip 154 ​​is fixed to the outer wall of the slider 150 by bolts.

[0027] It is worth noting that the locking piece 132 is fitted to the front side of the mounting rail 100, and the snap-fit ​​block 121 is fitted to both sides of the mounting rail 100.

[0028] It is worth noting that the snap-fit ​​130 slides onto the top of the snap-fit ​​groove 110.

[0030] Working principle: By setting a snap-fit ​​member 130 on the mounting rail 100 that mates with the snap-fit ​​groove 110, when the snap-fit ​​block 121 mates with the snap-fit ​​strip 111 and the main body 120 is placed on the mounting rail 100, the snap-fit ​​member 130 can be pushed to make the insertion strip 131 engage with the insertion groove 122 of the snap-fit ​​block 121. Then, tightening the locking knob 133 can achieve quick snap-fit ​​of the circuit breaker, thereby enabling quick assembly and disassembly of the circuit breaker, facilitating disassembly, inspection, maintenance and replacement of the circuit breaker, eliminating the need for... This method eliminates the hassle of using tools to tighten multiple bolts and saves manpower. After the circuit breaker is installed, the sliding member 150 can be slid outward in conjunction with the fixed member 140. At this time, the sliding member 150 is engaged with the front wall of the circuit breaker. Then, the locking bolt 141 is tightened to lock the sliding member 150. Next, the axial fan 153 is turned on so that it is aimed at the front wall of the circuit breaker, thereby achieving air cooling of the circuit breaker, improving the heat dissipation effect of the circuit breaker, and reducing the amount of dust in the air falling on the front wall of the circuit breaker.
