DETAILED DESCRIPTION

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an embodiment of the present invention provides a circuit breaker that is easy to disassemble and assemble, comprising: a circuit breaker body 1 and a mounting base 2, wherein the circuit breaker body 1 is detachably mounted in the mounting base 2; a limit assembly 3, wherein the limit assembly 3 is provided with two groups, and the limit assembly 3 includes a clamping component 301 and a fixing component 302, wherein the clamping component 301 is rotatably mounted on the mounting base 2, a clamping block 6 is provided on one side of the circuit breaker body 1, and the clamping component 301 is clamped with the clamping block 6, and the fixing component 302 is provided on the mounting base 2, and the fixing component 302 is clamped with the clamping component 301;

[0025] Specifically, such as Figures 1 to 4 As shown, the mounting base 2 is fixed at the mounting position by screws, and then the fixing component 302 is pulled, and then the clamping component 301 is toggled toward one end. At this time, the fixing component 302 is released, which limits the clamping component 301 and makes the clamping component 301 in an inclined state. Then, the circuit breaker body 1 is inserted into the mounting base 2, and the fixing component 302 is pulled to restore the clamping component 301 to its original position. At this time, one end of the clamping component 301 is inserted into the clamping block 6 to limit and fix the circuit breaker body 1. Conversely, according to the above steps, the reverse operation can be performed to complete the disassembly, thereby facilitating the disassembly and assembly of the circuit breaker body 1 and improving the convenience of maintenance.

[0026] Furthermore, the clamping component 301 includes a connecting rod 3011, a docking port is provided at the lower end of the connecting rod 3011, a limiting rod 3015 is provided inside the docking port, and the docking port is provided corresponding to the clamping block 6;

[0027] Specifically, such as Figures 2 to 4As shown, when the circuit breaker body 1 is inserted into the mounting seat 2, the position of the block 6 is located at the initial position of the docking interface. Therefore, when the connecting rod 3011 is reset, the limiting rod 3015 will be inserted into the block 6, thereby achieving the effect of conveniently fixing the block 6.

[0028] Furthermore, a rotating shaft 3013 is provided in the middle of the connecting rod 3011, and slots are provided at both the upper and lower ends of the mounting base 2. The rotating shaft 3013 is disposed in the slots. Torsion springs 3014 are provided at both ends of the rotating shaft 3013. The ends of the torsion spring 3014 are respectively provided on the connecting rod 3011 and the mounting base 2.

[0029] Specifically, such as Figure 4 As shown, due to the characteristics of the torsion spring 3014 itself, after the connecting rod 3011 is rotated by the rotating shaft 3013, it is only necessary to loosen the connecting rod 3011. At this time, the torsion spring 3014 will automatically reset the connecting rod 3011, thereby improving the convenience of use.

[0030] Furthermore, a groove is formed on the upper end of the connecting rod 3011, and an auxiliary handle 3012 is rotatably mounted in the groove, and a through groove is formed at one end of the auxiliary handle 3012;

[0031] Specifically, such as Figure 4 As shown, when in use, the auxiliary handle 3012 can be unfolded to provide a support point for the user. When not in use, the auxiliary handle 3012 can be retracted into the connecting rod 3011 to be hidden, thereby achieving the effect of avoiding interference with the use of other equipment when not in use.

[0032] Furthermore, the fixing member 302 includes a fixing seat 3021 and a docking seat 3025. A clamping rod 3024 is slidably mounted in the fixing seat 3021. The docking seat 3025 is disposed on the upper surface of the auxiliary handle 3012. The clamping rod 3024 is clamped with the docking seat 3025. A push block 3022 is disposed at the upper end of the clamping rod 3024. A return spring 3023 is disposed at one end of the clamping rod 3024. One end of the return spring 3023 is disposed at one end of the inner wall of the fixing seat 3021.

[0033] Specifically, such as Figure 4 As shown, the user pushes the push block 3022 to make the locking rod 3024 slide to one end and be pulled out from the docking seat 3025. At this time, the connecting rod 3011 can move. On the contrary, when the push block 3022 is released, the locking rod 3024 will slide to the other end through the reset spring 3023 and be reinserted into the docking seat 3025 to fix the locking rod 3024, thereby achieving the effect of convenient and quick fixation.

[0034] Furthermore, a buffer pad 5 is provided in the middle of the inner wall of the mounting base 2, a card slot 4 is provided on both sides of the inner wall of the mounting base 2, and a docking block 7 is provided on both sides of the circuit breaker body 1, and the docking block 7 is engaged with the card slot 4;

[0035] Specifically, such as Figure 2 As shown, the buffer pad 5 can reduce the friction between the circuit breaker body 1 and the mounting base 2 during installation, and the mutual cooperation between the card slot 4 and the docking block 7 facilitates the positioning of the circuit breaker body 1 during installation to avoid deviation and affect the installation.

[0036] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
