[0002] The circuit breaker is generally installed in the distribution box through the circuit breaker mounting bracket. When installing the circuit breaker, the circuit breaker is usually first installed on the mounting bracket, and then the mounting bracket is installed in the distribution box. When the circuit breaker needs to be replaced or repaired, the circuit breaker needs to be removed from the mounting bracket for replacement or repair.

[0003] During the replacement process of the circuit breaker, the types and sizes of the circuit breakers are different, and different types of mounting brackets need to be replaced for different types of circuit breakers. Therefore, when replacing different types of circuit breakers, the mounting brackets need to be disassembled and replaced together, which reduces the replacement efficiency of the circuit breaker. In addition, the traditional circuit breaker brackets are usually fixed in height and cannot be adjusted according to specific needs. This brings inconvenience to installation and maintenance, especially in the installation of circuits at different heights. Utility Model Content

[0029] like Figures 1 to 4 As shown, an adjustable mounting bracket for a molded case circuit breaker includes a circuit breaker body 1, at least two bracket bodies are provided at the bottom thereof, and each of the bracket bodies includes:

[0030] Two transverse support plates 2 are arranged in an upper and lower layer, and one of the transverse support plates 2 is arranged in a close relationship with the bottom of the circuit breaker body 1;

[0031] Two mounting holes are respectively arranged in the middle of the transverse support plate 2, the mounting holes are aligned with the holes on the circuit breaker body 1, and the two transverse support plates 2 are adjusted by telescopic adjustment to lengthen or shorten the length of the mounting holes;

[0032] Two longitudinal support plates 3 are respectively arranged at one end of the transverse support plate 2, and an adjustment component 4 is provided between each of the longitudinal support plates 3 and the transverse support plate 2, and the adjustment component 4 is used to adjust the position of the transverse support plate 2 on the longitudinal support plate 3;

[0033] The two locking portions 5 are respectively arranged at one end of the longitudinal support plate 3 away from the transverse support plate 2 , and each of the locking portions 5 is fixedly connected to the longitudinal support plate 3 .

[0034] For example, when in use, the two horizontal support plates 2 are moved in parallel to the maximum length to match the models of all circuit breaker bodies 1 of the maximum length, and then, the screws are inserted from the holes of the circuit breaker body 1 into the mounting holes, and then the nuts are put on the parts through which the screws are inserted, and the screws and nuts are controlled by a screwdriver to lock together to complete the installation of the circuit breaker body 1 and the two horizontal support plates 2, and then according to the installation requirements of the distribution cabinet or other scenarios, the position of the horizontal support plate 2 on the longitudinal support plate 3 is adjusted by adjusting the component 4 to determine the installation height of the circuit breaker body 1 in this scenario, and finally, it is fixed in the distribution cabinet by the locking part 5 to complete the installation of the entire circuit breaker body 1 and the distribution cabinet. When repairing or replacing the circuit breaker body 1, it is only necessary to loosen the screws and nuts to complete the installation of circuit breaker bodies 1 of different models, thereby solving the problem that the existing circuit breaker mounting bracket cannot be adjusted according to specific needs.

[0035] As an optional embodiment, the mounting hole is a first waist-shaped through hole 6 .

[0036] For example, by setting the mounting hole as the first waist-shaped through hole 6 , there is no need to align the holes according to different types of circuit breaker bodies 1 , which greatly saves the installation efficiency of the circuit breaker body 1 .

[0037] As an optional embodiment, the adjustment component 4 includes:

[0038] A first extension plate 7 is vertically fixed on one end of the transverse support plate 2 close to the longitudinal support plate 3;

[0039] at least one threaded hole 8, provided on the first extension plate 7;

[0040] at least one screw 9, threadedly disposed in the threaded hole 8;

[0041] At least one second waist-shaped through hole 10 is arranged in the middle along the length direction of the longitudinal support plate 3 , and the second waist-shaped through hole 10 is sleeved on the screw 9 .

[0042] For example, when adjusting the height, the screw 9 is loosened to allow the longitudinal support plate 3 to slide on the screw 9 through the second waist-shaped through hole 10 to adjust the position, and then the screw 9 is tightened to fix the longitudinal support plate 3 on the first extension plate 7, thereby completing the height adjustment.

[0043] As an optional embodiment, baffles 11 are vertically fixedly disposed on the sides of one of the transverse support plates 2 , and each of the baffles 11 is disposed in close proximity to the sides of the other transverse support plate 2 .

[0044] For example, the baffle 11 is used to ensure that the other transverse support plate 2 does not shift in position when sliding, and at the same time, ensure that the transverse support plate 2 and the circuit breaker body 1 are tightly fitted when installed.

[0045] As an optional embodiment, the locking portion 5 includes a second extension plate 12 which is fixedly connected to the longitudinal support plate 3 in a vertical state, and at least one adjustment hole 13 is provided on the second extension plate 12 .

[0046] As an optional embodiment, the adjustment hole 13 is a screw hole or a long hole.

[0047] For example, when the adjustment hole 13 is a long hole, by setting a second extension plate 12 on the longitudinal support plate 3 and setting an adjustment hole 13 on the second extension plate 12, when replacing a circuit breaker body 1 of a different model, in addition to loosening the screws and nuts on the transverse support plate 2 for adjustment, the screws on the long hole can also be loosened according to the needs of the situation to adjust the length of the transverse support plate 2, so that the transverse support plate 2 can better fit the length of the circuit breaker body 1 for adjustment, thereby improving the stability between the entire mounting bracket and the circuit breaker body 1.
