Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker technology, and in particular relates to a stabilizing component for circuit breakers. Background Technology

[0002] A circuit breaker is an important electrical device that can close, carry, and interrupt current under normal circuit conditions, and at the same time, close, carry, and interrupt current under abnormal circuit conditions within a specified time. The main functions of a circuit breaker are to disconnect and connect load circuits, as well as to disconnect faulty circuits, thereby preventing accidents from escalating and ensuring the safe operation of the circuit.

[0003] The problem with existing technology is that existing circuit breakers are usually installed on guide rails and are subject to the pulling and dropping forces of the lines over a long period of time, which makes them unstable. Over time, this can easily cause the circuit breaker to deviate from the guide rail, thus affecting the stability and safety of the connection. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a stabilizing component for circuit breakers. It has the advantages of strengthening the stability of the circuit breaker, preventing the circuit breaker and the guide rail from shifting, and improving the stability and safety of the connection to a certain extent. It solves the problem that existing circuit breakers, which are usually installed on the guide rail, are subjected to the pulling and downward forces of the lines for a long time, and are not stable. Over time, this can easily lead to the circuit breaker shifting from the guide rail, thus affecting the stability and safety of the connection.

[0005] This utility model is implemented as follows: a stabilizing component for a circuit breaker includes a housing, a guide rail, and a circuit breaker. The guide rail is disposed at the lower end of the housing and is fixedly connected to the rear surface of the housing. There are three circuit breakers, all disposed at the front end of the guide rail and movably connected to the guide rail. A stabilizing device is disposed at the rear end of the circuit breaker and is fixedly connected to the housing.

[0006] The preferred stabilizing device of this utility model includes a clamping assembly, a linkage assembly, and a control assembly. There are two clamping assemblies, which are respectively arranged on the upper and lower sides of the rear end of the circuit breaker. The linkage assembly is arranged on the right side of the two linkage assemblies, and the control assembly is arranged on the right side of the linkage assembly. By setting up the stabilizing device, the circuit breaker is stabilized, avoiding the circuit breaker from being subjected to tensile force for a long time after the circuit is connected to the line, which would cause the circuit breaker and the guide rail to shift, thus ensuring the stability of the circuit breaker on the guide rail.

[0007] The preferred clamping assembly of this utility model includes a movable seat, a clamping plate, a push plate, and a travel groove. Two movable seats are respectively disposed on the left and right sides above the guide rail, and their rear ends are fixedly connected to the rear surface of the housing. The clamping plate is sleeved on the surfaces of the two movable seats and slidably connected to them. The push plate is fixedly connected to the rear side of the upper surface of the clamping plate. The travel groove is formed on the front surface of the push plate and passes through it. By providing the clamping assembly, the circuit breaker is clamped on both the upper and lower sides, thereby stabilizing the circuit breaker and preventing it from shifting due to force.

[0008] The preferred linkage component of this utility model includes an extrusion shaft, a pull rod, and a connecting plate. There are two extrusion shafts, each disposed within one of the two stroke grooves and movably connected to them. Both ends of the two extrusion shafts extend out of the stroke grooves. There are two pull rods, each disposed behind one of the two push plates. The left ends of the two pull rods are fixedly connected to the lower ends of the two extrusion shafts, and the connecting plate is fixedly connected to the right ends of the two pull rods. This linkage component drives and controls the clamping components, simultaneously causing the two clamping components to open and close synchronously.

[0009] The preferred control component of this utility model includes a screw, a threaded sleeve, and a rotating seat. The screw is rotatably connected to the right side of the connecting plate. The threaded sleeve is fitted onto the surface of the screw and threadedly connected to it. The rotating seat is fitted onto the surface of the threaded sleeve and rotatably connected to it. The rear end of the rotating seat is fixedly connected to the rear surface inside the housing. By setting the control component, it is used to drive and control the stabilizing device. It has the function of driving the linkage component to control the two clamping components to clamp and release the circuit breaker, and also plays a role in positioning the linkage component.

[0010] As a preferred embodiment of this invention, rubber anti-slip pads are fixedly connected to the surfaces of the two clamping plates that are close to each other. By providing rubber anti-slip pads on the surfaces of the two clamping plates that are close to each other, the clamping plates can play a role in preventing slippage and protection, and avoid scratching the circuit breaker.

[0011] In a preferred embodiment of this invention, a rotating ring is fitted onto the middle end surface of the threaded sleeve. The rotating ring is fixedly connected to the threaded sleeve, and the rotating seat extends outward and is rotatably connected to the rotating seat. By fitting a rotating ring onto the middle end surface of the threaded sleeve, the threaded sleeve can be rotated, thus facilitating the control of the stabilizing device by rotating the threaded sleeve.

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

[0013] 1. This utility model solves the problem that existing circuit breakers, which are usually installed on guide rails, are subject to the pulling and sagging forces of the lines over a long period of time, and are not stable. This can easily lead to the circuit breaker deviating from the guide rail over time, thus affecting the stability and safety of the connection. Attached Figure Description

Detailed Implementation

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a stabilizing component for a circuit breaker, including a housing 1, a guide rail 2 and a circuit breaker 3. The guide rail 2 is disposed at the lower end of the housing 1 and is fixedly connected to the rear surface of the housing 1. There are three circuit breakers 3, all of which are disposed at the front end of the guide rail 2 and are movably connected to the guide rail 2. A stabilizing device 4 is disposed at the rear end of the circuit breaker 3 and is fixedly connected to the housing 1.

[0022] refer to Figure 1 and Figure 2The stabilizing device 4 includes a clamping component 41, a linkage component 42, and a control component 43. There are two clamping components 41, which are respectively located on the upper and lower sides of the rear end of the circuit breaker 3. The linkage component 42 is located on the right side of the two linkage components 42, and the control component 43 is located on the right side of the linkage component 42.

[0023] The above solution is adopted: by setting a stabilizing device 4, the circuit breaker 3 is stabilized, which prevents the circuit breaker 3 from being subjected to tensile force for a long time after the circuit is connected, thus avoiding the displacement of the circuit breaker 3 and the guide rail 2, and ensuring the stability of the circuit breaker 3 on the guide rail 2.

[0024] refer to Figure 2 and Figure 3 The clamping assembly 41 includes a movable seat 411, a clamping plate 412, a push plate 413, and a travel groove 414. There are two movable seats 411, which are respectively arranged on the left and right sides above the guide rail 2, and their rear ends are fixedly connected to the rear surface of the inner side of the housing 1. The clamping plate 412 is sleeved on the surface of the two movable seats 411 and is slidably connected to the movable seats 411. The push plate 413 is fixedly connected to the rear side of the upper surface of the clamping plate 412. The travel groove 414 is opened on the front surface of the push plate 413 and passes through the push plate 413.

[0025] The above solution is adopted: by setting up a clamping component 41, the circuit breaker 3 is clamped on the upper and lower sides, thereby stabilizing the circuit breaker 3 and preventing the circuit breaker 3 and the guide rail 2 from shifting due to force.

[0026] refer to Figure 2 and Figure 3 The linkage component 42 includes an extrusion shaft 421, a pull rod 422, and a connecting plate 423. There are two extrusion shafts 421, which are respectively set in two stroke grooves 414 and are movably connected to the stroke grooves 414. The front and rear ends of the two extrusion shafts 421 extend out of the stroke grooves 414. There are two pull rods 422, which are respectively set behind the two push plates 413. The left ends of the two pull rods 422 are fixedly connected to the lower ends of the two extrusion shafts 421, and the connecting plate 423 is fixedly connected to the right ends of the two pull rods 422.

[0027] The above scheme is adopted: by setting up a linkage component 42, it is used to drive and control the clamping component 41, and has the function of simultaneously driving the two clamping components 41 to open and close synchronously.

[0028] refer to Figure 3 and Figure 4The control component 43 includes a screw 431, a threaded sleeve 432, and a rotating seat 433. The screw 431 is rotatably connected to the right side of the connecting plate 423. The threaded sleeve 432 is sleeved on the surface of the screw 431 and threadedly connected to the screw 431. The rotating seat 433 is sleeved on the surface of the threaded sleeve 432 and rotatably connected to the threaded sleeve 432. The rear end of the rotating seat 433 is fixedly connected to the rear surface inside the housing 1.

[0029] The above scheme is adopted: by setting up a control component 43, it is used to drive and control the stabilizing device 4. It has the function of driving the linkage component 42 to drive and control the two clamping components 41 to clamp and release the circuit breaker 3, and at the same time, it also plays a role in positioning the linkage component 42.

[0030] refer to Figure 2 and Figure 3 Both clamping plates 412 have rubber anti-slip pads 5 fixedly connected to their close surfaces.

[0031] The above solution is adopted: rubber anti-slip pads 5 are provided on the surfaces of the two clamping plates 412 that are close to each other, so as to play an anti-slip and protective role during clamping and avoid scratching the circuit breaker 3.

[0032] refer to Figure 4 A rotating ring 6 is fitted on the middle end surface of the threaded sleeve 432. The rotating ring 6 is fixedly connected to the threaded sleeve 432, and a rotating seat 433 extends outward from the outside and is rotatably connected to the rotating seat 433.

[0033] The above solution is adopted: by fitting a rotating ring 6 on the middle surface of the threaded sleeve 432, the threaded sleeve 432 is rotated, which facilitates the control of the stabilizing device 4 by rotating the threaded sleeve 432.

[0034] The working principle of this utility model:

[0035] When stable, the threaded sleeve 432 is rotated by rotating ring 6. As the threaded sleeve 432 rotates within the rotating seat 433, it drives the threaded screw 431 to move to the left. The leftward movement of the screw 431 pushes the connecting plate 423, causing the two pull rods 422 to move to the left. Simultaneously, the two pull rods 422 move to the left, causing the two extrusion shafts 421 to move and extrude within the two stroke grooves 414, pressing against the inner walls of the grooves. This causes the two push plates 413 to be compressed, pushing the two clamping plates 412 together. The two clamping plates 412 are then pushed against the surface of the moving seat 411. The components move together to clamp and secure the circuit breaker 3. When releasing the clamping, the threaded sleeve 432 is rotated in the opposite direction by rotating the ring 6. The rotation of the threaded sleeve 432 drives the screw 431 to move to the right. The movement of the screw 431 to the right pulls the connecting plate 423 to the right. The connecting plate 423 drives the two pull rods 422 to move to the right. At the same time, the movement of the two pull rods 422 to the right drives the extrusion shaft 421 to move to the right in the stroke groove 414 and extrude. This causes the push plate 413 to be extruded and move to the upper and lower sides. At the same time, the movement causes the clamping plates 412 on both sides to move away from each other, thereby releasing the clamping.

[0036] In summary, this stabilizing component for circuit breakers, through the coordinated use of a housing 1, guide rail 2, circuit breaker 3, stabilizing device 4, clamping assembly 41, moving seat 411, clamping plate 412, push plate 413, stroke groove 414, linkage assembly 42, pressing shaft 421, pull rod 422, connecting plate 423, control assembly 43, screw 431, threaded sleeve 433, rotating seat 434, rubber anti-slip pad 5, and rotating ring 6, solves the problem that existing circuit breakers, typically installed on guide rails, are subject to long-term pulling and downward forces from the lines, resulting in instability and a tendency for the circuit breaker to shift off the guide rail over time, thus affecting the stability and safety of the connection.
