[0023] The utility model provides a kind of safety distribution box of preventing misoperation as Figure 1 - Figure 4 As shown in a kind of safety distribution box of preventing misoperation, including box 1 and the multiple circuit breakers 3 of installation setting in the inside of box 1, box 1 is prior art, it is the common box 1 of existing distribution box, not too much is described here, circuit breaker 3 is the common device of existing safety distribution box, mainly for carrying out automatic circuit breaking work, when circuit appears abnormal, such as short circuit, overload or undervoltage etc., when short circuit occurs, the magnetic field of large current generation can overcome counterforce spring, make the tripping device pull operating mechanism action, switch instantaneous trip, cut off circuit, when overload, current becomes large, heat generation aggravates, thermal tripping device thermal element in circuit breaker 3 can heat, make bimetallic strip deform to a certain degree after pushing mechanism action, current is larger, action time is shorter, to cut off circuit, when circuit breaker 3 starts, the control switch on its upper end will be automatically tripped downward, to complete the automatic protection of circuit, it is prior art, not too much is described here, one end of box 1 is rotatably provided with upper door 2, one end of box 1 is also rotatably provided with lower door, as shown in figure Figure 1 The upper door 2 is set in a flip-open manner, facilitating the opening of the upper door 2. The upper door 2 and the lower door are both prior art, and will not be described in detail here. The upper door 2 is arranged corresponding to the circuit breaker 3, and the circuit breaker 3 can be operated by opening the upper door 2.

[0024] A rectangular rod 4 is movably arranged inside the box 1. A plurality of closed heads 5 are fixedly arranged on the upper end of the rectangular rod 4. The closed heads 5 abut against the switches of the circuit breakers 3. Rectangular blocks 6 are fixedly arranged on both sides of the inner wall of the box 1. A rectangular slot 9 is formed in one end of each rectangular block 6. The end portion of the rectangular rod 4 is slidably arranged inside the corresponding rectangular slot 9. An L-shaped rod 7 is movably arranged inside the rectangular slot 9. The end portion of the L-shaped rod 7 is fixedly connected to the end portion of the rectangular block 6. A spring 8 is fixedly arranged on one end of the L-shaped rod 7. The end portion of the spring 8 is fixedly connected to the inner wall of the rectangular slot 9.

[0025] When the spring 8 works, it extrudes the L-shaped rod 7, so that the L-shaped rod 7 extrudes the rectangular rod 4. The rectangular rod 4 moves the plurality of closed heads 5 on the upper end, so that the closed heads 5 extrude the switches of the circuit breakers 3 at all times. Through the arrangement of the plurality of closed heads 5 on the rectangular rod 4, when the operator opens the box 1, the closed heads 5 can protect the switches of the circuit breakers 3, and prevent the error power failure caused by the direct misoperation of the operator. When the circuit breaker 3 is closed, the rectangular rod 4 needs to be additionally opened, which increases the time for the operator to consider and judge.

[0026] The center shaft 10 is fixed on the inner wall of the box body 1, and the center rod 11 is movably arranged on the inner wall of the box body 1. One end of the upper door 2 abuts against the end of the center rod 11, and when the upper door 2 is closed, the end of the center rod 11 is pressed, so that the center rod 11 rotates. The center rod 11 can only rotate around the center shaft 10, and the center shaft 10 is located at the center of the center rod 11. The L-shaped rod 7 is fixedly provided with a guide plate 12, and the end of the center rod 11 abuts against the guide plate 12.
