Description

Technical Field

[0001] This utility model relates to the field of residual current circuit breaker installation technology, specifically to a residual current circuit breaker that is easy to replace. Background Technology

[0002] A residual current circuit breaker (RCCB) is a commonly used circuit protector. RCCBs have the function of cutting off AC circuits when leakage occurs, thus preventing AC circuit failures. Most RCCBs are currently installed on the walls of users' homes to protect their household electricity usage.

[0003] Because a residual current circuit breaker (RCCB) is an electrical component, its lifespan is quite limited. When an RCCB is damaged and unusable, the usual practice is to replace it with a new one. However, when replacing an RCCB, it's often difficult to quickly remove the old one, leaving many marks on the wall and affecting its overall aesthetics. Installing a new RCCB is also challenging; it's often secured with screws, which generally results in weak stability and a risk of falling, posing a safety hazard to users and lacking advanced intelligent features.

[0004] Therefore, it is particularly important to design an easily replaceable residual current circuit breaker to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

The circuit breaker body has symmetrically embedded mounting sockets at both the top and bottom ends of its left and right sides. The fixed back plate has guide rails fixed at both the top and bottom ends of its left and right sides. Slide blocks are slidably connected to the outer sides of the guide rails. Clamping push plates are fixedly installed between two sets of slide blocks on the same side. Mounting pins for use with the mounting sockets are provided on the opposite side of the two sets of clamping push plates near the four corners. A crossbar support extending along the length of the fixed back plate is provided at the top of the fixed back plate. A forward / reverse motor is installed on the right side of the crossbar support. A drive shaft is provided on the inner side of the crossbar support. Drive screws with opposite threads are welded to both ends of the drive shaft. One end of one set of drive screws passes through the crossbar support and connects to the output end of the forward / reverse motor. A screw sleeve is threaded onto the outer side of the drive screw.

[0007] As a preferred embodiment of this utility model, the fixed back plate and the circuit breaker body are designed to be detachable.

[0008] The above technical solution enables rapid fixing, avoiding the current situation where it is difficult to quickly and completely remove the old residual current circuit breaker when replacing it. It also solves the problem that the wall usually has many scars after removal, which affects the overall aesthetics of the wall.

[0009] As a preferred embodiment of this utility model, the fixed back plate has symmetrical mounting holes on both the left and right sides, and mounting bolts are installed inside the mounting holes. The fixed back plate also has a rectangular opening at the center for the wires to pass through.

[0010] The above technical solution is used for mounting on the wall without affecting the connection of electrical wires.

[0011] As a preferred embodiment of this utility model, a control switch is provided on the outer side of the fixed back plate, wherein the control switch is connected to the forward and reverse motors by a wire, and the connection is an electrical connection.

[0012] As a preferred embodiment of this utility model, the connection between the mounting socket and the mounting post is a plug-in connection, and the internal structure size of the mounting socket is adapted to the external structure size of the mounting post.

[0013] The above technical solution ensures a fast and stable connection.

[0014] As a preferred embodiment of this utility model, the inner side of the clamping push plate is fitted with a silicone anti-slip adhesive sticker.

[0015] The above technical solutions increase the stability of the fixed structure.

[0016] As a preferred embodiment of this utility model, the ends of the two sets of drive screws away from the drive shaft are rotatably connected to the inside of the crossbar bracket through bearing seats, and the other ends of the two sets of screw sleeves are respectively fixedly connected to the top of the corresponding slide block by bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, an easily replaceable residual current circuit breaker is designed. Through the coordinated arrangement of guide rails, slide blocks, clamping push plates, mounting posts, crossbar supports, forward and reverse motors, drive shafts, drive screws, and screw sleeves, the opening and closing of two sets of clamping push plates drives the mounting posts to plug and unplug into the mounting socket of the circuit breaker body, achieving rapid fixation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0022] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A replaceable residual current circuit breaker includes a fixed back plate 1 and a circuit breaker body 2. The upper and lower ends of the left and right sides of the circuit breaker body 2 are symmetrically embedded with mounting sockets 201. The upper and lower ends of the left and right sides of the front of the fixed back plate 1 are fixed with guide rails 3. The outer side of the guide rails 3 is slidably connected with a slide block 301. A clamping push plate 302 is fixedly installed between two sets of slide blocks 301 on the same upper and lower side. On the opposite side of the two sets of clamping push plates 302 and near the four corners, there are mounting posts 303 that cooperate with the mounting sockets 201. A crossbar bracket 4 extending along the length of the fixed back plate 1 is provided on the top of the fixed back plate 1.

[0023] The fixed back plate 1 and the circuit breaker body 2 are designed to be detachable, which enables quick fixing and avoids the current situation where it is difficult to quickly and completely remove the old residual current circuit breaker when replacing it. It also solves the problem that there are usually many scars on the wall after removal, which affects the overall aesthetics of the wall. The fixed back plate 1 has symmetrical mounting holes on both the left and right sides inside, and mounting bolts are installed inside the mounting holes. The fixed back plate 1 has a rectangular window inside the center for the wires to pass through, which is used to mount it on the wall without affecting the connection of the wires. The connection between the mounting socket 201 and the mounting post 303 is a plug-in connection. The internal structure of the mounting socket 201 is adapted to the external structure of the mounting post 303, and the connection is quick and stable. The inner side of the clamping push plate 302 is covered with silicone anti-slip adhesive to increase the stability of the fixation.

[0024] In this embodiment, a forward and reverse motor 401 is installed on the right side of the crossbar support 4, and a drive shaft 402 is provided on the inner side of the crossbar support 4. Drive screws 403 with opposite threads are welded to both ends of the drive shaft 402. One end of one set of drive screws 403 passes through the crossbar support 4 and is connected to the output end of the forward and reverse motor 401. A screw sleeve 404 is threaded onto the outer side of the drive screw 403. A control switch is provided on the outer side of the fixed back plate 1. The control switch is connected to the forward and reverse motor 401 by a wire and the connection is electrical. The ends of the two sets of drive screws 403 away from the drive shaft 402 are rotatably connected to the inside of the crossbar bracket 4 through bearing seats. The other ends of the two sets of screw sleeves 404 are respectively fixed to the top of the corresponding slide block 301 by bolts.

[0025] The working process of this utility model is as follows: When the easily replaceable residual current circuit breaker and structure designed in this scheme are in operation, the drive shaft 402 and the drive screws 403 at both ends of it are driven by the forward and reverse motor 401 to rotate. The threads of the two sets of drive screws 403 drive the screw sleeves 404 to move in the same or opposite directions, which in turn drives the slide block 301 on the guide slide rail 3 to move, causing the two sets of clamping push plates 302 to open or close. The opening and closing of the two sets of clamping push plates 302 drives the mounting plug 303 and the circuit breaker to move. The main body 2 is connected to the installation socket 201 by plugging and unplugging to achieve quick fixation. This structure, through the cooperation of guide rail, slide block, clamping push plate, installation plug, crossbar bracket, forward and reverse motor, drive shaft, drive screw and screw sleeve, enables the two sets of clamping push plates to quickly fix the circuit breaker body by opening and closing. This avoids the current situation where it is difficult to quickly and completely remove the discarded residual current circuit breaker when replacing it, and solves the problem that there are usually many scars on the wall after removal, which affects the overall aesthetics of the wall.
