一种断路器

Abstract

本实用新型涉及断路器技术领域，公开了一种断路器，其包括背板、壳体以及拆装组件；背板设置于断路器主体的一端；壳体设置于断路器主体的另一端，壳体与背板可拆卸连接；每个拆装组件均包括连接座，连接座的表面开设有插接槽，壳体的两侧分别设置有L形连接板，L形连接板与插槽相适配，每个连接座的一侧均滑动贯穿连接有限位块，L形连接板靠近限位块的一侧设置有限位槽，限位块滑设于限位槽的内部，限位块背离限位槽的一端依次连接有从动杆和从动齿板，从动齿板的一端啮合连接有驱动齿轮，驱动齿轮的内部固定设置有伸缩柱，本实用新型代替了传统断路器使用螺钉进行连接固定的方式，对断路器进行多次检修后不会出现螺孔滑丝的情况。

Claims

1. A circuit breaker characterized by, include: Circuit breaker body, backplate, housing, and assembly / disassembly components; The back plate is disposed at one end of the circuit breaker body; The housing is located at one end of the circuit breaker body away from the back plate, and the housing is detachably connected to the back plate; The number of disassembly / reassembly components is two, symmetrically arranged on both sides of the housing. These components control the fixing and separation between the housing and the back plate. Each component includes a connecting seat with a slot on its surface. L-shaped connecting plates are respectively provided on both sides of the housing, and these plates are inserted into the slots. A limiting block is slidably connected to one side of each connecting seat. A limiting groove is provided on the side of the L-shaped connecting plate closest to the limiting block, and the limiting block slides on... Inside the limiting groove, a driven rod and a driven toothed plate are sequentially connected to one end of the limiting block away from the limiting groove. A drive gear is meshed with one end of the driven toothed plate. A telescopic column is fixedly installed inside the drive gear. The rotation of the telescopic column drives the drive gear to rotate, thereby causing the driven toothed plate to move vertically. The driven toothed plate drives the driven rod to move vertically, causing the limiting block to disengage from the limiting groove. The L-shaped connecting plate then detaches from the insertion groove vertically to complete the separation of the housing and the back plate.

2. The circuit breaker of claim 1, wherein, It also includes a transmission assembly. The back plate has an inwardly recessed groove facing away from the housing. The transmission assembly is disposed in the groove. One end of the transmission assembly is connected to one of the disassembly and assembly components, and the other end is connected to the other disassembly and assembly component. The transmission assembly is used to ensure the synchronous rotation of the two telescopic columns.

3. The circuit breaker of claim 2, wherein, The transmission assembly includes a transmission rod, a first pulley, and a second pulley. There are at least two first pulleys and two second pulleys. The first pulley and the second pulley are respectively disposed at both ends of the transmission rod. The first pulley is sleeved on the outer periphery of the transmission rod, and the second pulley is sleeved on the outer periphery of the telescopic column. A belt is connected between the first pulley and the second pulley.

4. The circuit breaker of claim 1, wherein, It also includes two self-locking components, which are respectively disposed on both sides of the housing and are configured in a one-to-one correspondence with the disassembly and assembly components. The self-locking components are used to prevent the telescopic column from rotating unexpectedly.

5. The circuit breaker of claim 4, wherein, The self-locking assembly includes a positioning seat and a retaining ring. One end of the positioning seat is connected to the connecting seat. The telescopic column is disposed inside the positioning seat, and a retaining ring is connected to the outer periphery of the end of the telescopic column that extends out of the positioning seat. Multiple inserts are disposed on the outer periphery of the retaining ring. A slot recessed towards the drive gear is disposed at the end of the positioning seat near the retaining ring. The inserts and the slot are engaged to restrict the rotation of the telescopic column.

6. The circuit breaker of claim 5, wherein, The self-locking assembly also includes a return spring, which is disposed at one end of the telescopic column near the drive gear. The telescopic column is stretched horizontally to extend the return spring, causing the insertion post to disengage from the slot. The telescopic column rotates horizontally, thereby driving the drive gear to rotate.

7. The circuit breaker of claim 6, wherein, The self-locking component also includes a protective frame, which is disposed on the outer periphery of the positioning seat. A frame door is rotatably connected to one side of the protective frame, and a buckle block for fixing the frame door is provided on the other side of the protective frame. After the frame door is flipped in a direction away from the positioning seat, it provides clearance space for the extension and retraction of the telescopic column.

8. The circuit breaker of claim 7, wherein, The telescopic column is provided with a handle at the end opposite to the reset spring for the user to rotate the telescopic column.

9. The circuit breaker according to claim 1, characterized in that, Heat dissipation grooves are provided on both sides of the housing, and dustproof mesh is installed inside the heat dissipation grooves.

10. The circuit breaker of claim 1, wherein, Each of the back plates is provided with multiple mounting ears, and each mounting ear has a threaded connection to a positioning bolt.
