[0028] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. A circuit breaker bracket is required when installing a circuit breaker.

[0029] The leakage circuit breaker in the related art has the problem that, due to the lack of a bottom bracket, the electric energy meter lacks support from the bottom when installed on the bracket, and is prone to loosening.

[0030] Based on this, in order to improve the problems in the related art, the embodiments of the present application provide the following solutions.

[0031] Please also read Figure 1 and Figure 2 An embodiment of the present application provides a molded case circuit breaker main bracket, including a left bracket 1, a right bracket 2, a transverse bracket 3 and a limit bracket 4, one end of the transverse bracket 3 is connected to the left bracket 1, and the other end is connected to the right bracket 2, and the limit bracket 4 is rotatably connected between the left bracket 1 and the right bracket 2.

[0032] From the above, it can be seen that a molded case circuit breaker main bracket provided in an embodiment of the present application is provided with a rotatable and adjustable limit bracket 4, which can support the back of the circuit breaker when installing the circuit breaker, and cooperate with the left bracket 1 and the right bracket 2 to more firmly fix the circuit breaker, and can also make the installation and disassembly process of the circuit breaker more convenient.

[0033] In some embodiments, please refer to Figure 1 to Figure 2Rivets 11 are provided on the left bracket 1 and the right bracket 2, first mounting holes 12 are opened on the left bracket 1 and the right bracket 2, a second mounting hole 41 is opened on the limiting bracket 4, and the limiting bracket 4 is rotatably connected between the left bracket 1 and the right bracket 2 through the rivets 11.

[0034] With such arrangement, the limiting bracket 4 can rotate around the rivet 11 , and when installing or disassembling the circuit breaker, the staff can flexibly adjust the limiting bracket 4 to a suitable position according to the size of the circuit breaker.

[0035] Optionally, in some embodiments, see Figure 1 to Figure 2 An arc-shaped slide groove 13 is provided on the left bracket 1 and the right bracket 2, a third mounting hole 42 is provided on the limit bracket 4, an adjusting bolt 131 is slidably connected in the slide groove 13, and the limit bracket 4 is connected to the adjusting bolt 131 through the third mounting hole 42.

[0036] With such arrangement, after adjusting the position of the limit bracket 4, the adjustment bolt 131 can be tightened to fix the limit bracket 4, and the circuit breaker can be directly removed by loosening the adjustment nut when disassembling the circuit breaker, which facilitates the installation and disassembly of the circuit breaker.

[0037] Optionally, see Figure 1 to Figure 2 A support piece 43 is provided at one end of the limiting bracket 4 away from the second mounting hole 41 , and the support piece 43 is welded to the limiting bracket 4 .

[0038] With such arrangement, the contact surface between the support piece 43 and the back of the circuit breaker is arc-shaped, and the height of the limit bracket 4 can be adjusted arbitrarily to ensure that the support piece 43 has a larger contact area with the back of the circuit breaker, thereby ensuring the stability of the circuit breaker installation.

[0039] In some embodiments, see Figure 1 to Figure 2 A plurality of limiting holes 14 and limiting openings 15 are provided on the left bracket 1 and the right bracket 2 .

[0040] With such arrangement, the limiting holes 14 and the limiting openings 15 on the left bracket 1 and the right bracket 2 can match with corresponding connections on the circuit breaker, further enhancing the stability of the installation of the circuit breaker.

[0041] Optionally, in some embodiments, see Figure 1 to Figure 2 A clamping plate 16 is provided on both the left bracket 1 and the right bracket 2 , and the opening direction of the clamping plate 16 on the right bracket 2 is opposite to the opening direction of the clamping plate 16 on the left bracket 1 .

[0042] With such arrangement, multiple circuit breakers may need to be installed during actual use of the circuit breaker. When multiple circuit breaker brackets are installed side by side, the clamping plates 16 on adjacent sides can be clamped together, so that the mutually clamped circuit breaker brackets become a more stable whole.

[0043] Optionally, see Figure 1 to Figure 2 A connecting plate 17 is provided at the bottom of the left bracket 1 and the bottom of the right bracket 2 , and a threaded hole 171 is opened on the connecting plate 17 .

[0044] With such arrangement, the circuit breaker bracket can be fixed on the wall through the connecting plate 17, and the connecting plates 17 at staggered positions can allow the circuit breaker brackets installed side by side to be connected more closely, thus saving the space required for installing multiple circuit breakers.

[0045] In some embodiments, see Figure 1 to Figure 2 A limiting strip 21 is provided on the top of the right bracket 2 .

[0046] With such arrangement, the limit strip 21 is used to abut against the front face of the circuit breaker during the installation of the circuit breaker to prevent the circuit breaker from moving upward, thereby making the installation of the circuit breaker more stable.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
