Technical Field

[0001] This utility model relates to the field of residual current devices (RCDs), and more particularly to an RCD that is easy to install. Background Technology

[0002] As a core device for circuit safety protection, residual current devices (RCDs) are widely used in home and industrial settings. Their ease of installation and level of intelligent functionality directly affect user experience and maintenance efficiency.

[0003] Traditional residual current devices (RCDs) are mostly installed in distribution boxes or on walls using bolts. While bolt fixing offers stability, it is prone to problems such as stripping and corrosion after long-term use, leading to difficult disassembly and increased maintenance or replacement costs. Some improved solutions attempt to simplify installation using clips or flexible components, such as using hanging grooves and flexible support strips for suspended installation. However, these designs are often structurally complex and have limited adaptability to the installation environment, making it difficult to balance quick installation / disassembly with long-term stability. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-install residual current device (RCD) to solve the problem that in the prior art, RCDs are usually installed directly using bolts, and the bolts may strip or rust if they are not moved for a long time, making subsequent disassembly, maintenance and replacement very inconvenient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a leakage current protector that is easy to install, comprising a base assembly, a mounting assembly, and a protector body, wherein the base assembly includes a mounting bracket and a mounting groove formed on the mounting bracket, and the mounting groove is provided with positioning grooves evenly distributed inside;

[0006] The mounting assembly includes a connector and an adjusting member installed inside the connector. One end of the adjusting member is connected to a transmission member, and the other end of the transmission member is connected to a fixing member.

[0007] The protector body is fixedly connected to the mounting assembly.

[0008] Preferably, the connecting seat moves horizontally within the mounting groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a leakage current protector that is easy to install, including a base assembly 10, a mounting assembly 20 and a protector body 30. The base assembly 10 includes a mounting frame 11 and a mounting groove 12 opened on the mounting frame 11. The mounting groove 12 is evenly provided with positioning grooves 13 inside. The mounting frame 11 is installed on the wall or a corresponding installation position by fixing bolts. The mounting groove 12 is engaged with the mounting frame 11 to cooperate with the mounting assembly 20 for installation. The positioning grooves 13 are evenly distributed at equal intervals inside the mounting groove 12.

[0023] The mounting assembly 20 includes a connecting base 21 and an adjusting member 22 installed inside the connecting base 21. One end of the adjusting member 22 is connected to a transmission member 23, and the other end of the transmission member 23 is connected to a fixing member 24. The connecting base 21 is fixedly mounted on the protector body 30. A protrusion structure is provided on the lower side of the connecting base 21 for mating with the mounting groove 12. The protector body 30 is fixedly connected to the mounting assembly 20.

[0024] The adjusting component 22 includes a pressing head 221 and a connecting rod 222 fixedly connected to one end of the pressing head 221. The other end of the connecting rod 222 is connected to a transmission sleeve 223. A transmission cam 224 is fixedly connected to the transmission sleeve 223. A first spring 225 is provided on one side of the pressing head 221.

[0025] The connecting rod 222 has a sliding surface on its outer side, which is used to limit its movement inside the connecting seat 21, thereby restricting the movement of the connecting rod 222 and ensuring that the connecting rod 222 can only move horizontally and cannot rotate. At the same time, one end of the connecting rod 222 is provided with a mating rod, and the transmission sleeve 223 has a mating groove. The mating rod on the connecting rod 222 moves within the mating groove on the transmission sleeve 223. One end of the first spring 225 is fixedly connected to the pressing head 221, and the other end is fixedly connected to the inside of the connecting seat 21.

[0026] The transmission component 23 includes an intermediate connecting block 231 and a displacement limiting block 232 fixedly connected to the intermediate connecting block 231, and a second spring 233 is connected to one side of the displacement limiting block 232; wherein, the upper part of the intermediate connecting block 231 is provided with a mating arc groove for connecting and mating with the adjusting component 22, and the other end of the intermediate connecting block 231 is provided with an inclined surface, and the two ends of the second spring 233 are fixedly connected to the displacement limiting block 232 and the connecting seat 21 respectively.

[0027] The fastener 24 includes a fastening block 241 and a wedge-shaped groove 242 formed inside the fastening block 241, and a third spring 243 is fixedly connected to one end of the fastening block 241.

[0028] The fixed block 241 has an inclined surface on one side of its lower end to facilitate the engagement between the connecting seat 21 and the mounting groove 12. The other side opposite to the inclined surface is set at a right angle so that the fixed block 241 engages with the positioning groove 13 to complete the installation and fixing of the mounting component 20. At the same time, the wedge groove 242 has an inclined surface inside that can engage with the inclined surface on the intermediate connecting block 231, so that the movement of the intermediate connecting block 231 can move the fixed block 241, which facilitates the subsequent movement and disassembly of the device.

[0029] The working principle and usage process of this utility model are as follows: During installation, simply snap the protector body 30 onto the mounting bracket 11, and use the connecting seat 21 to snap it into the inside of the mounting groove 12. The fixed installation connection of the protector body 30 is completed by the engagement between the fixing block 241 and the positioning groove 13. Simultaneously, when it is necessary to move the position of the protector body 30 or disassemble it, simply press the pressing head 221. The pressing head 221 will drive the connecting rod 222 to move. At this time, since the connecting rod 222 is positioned within the connecting seat 21... The internal limit switch allows for horizontal movement only, not rotation. This allows the connecting rod 222 to move within the groove on the transmission sleeve 223, causing the transmission sleeve 223 to drive the transmission cam 224 to rotate. The transmission cam 224 then engages with the intermediate connecting block 231, causing the intermediate connecting block 231 to move. The engagement between the intermediate connecting block 231 and the wedge groove 242 causes the fixing block 241 to retract and disengage from the positioning groove 13, thus completing the movement or disassembly of the protector body 30.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
