[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is somewhat blurred; generally, circuit breakers above 3kV are referred to as high-voltage electrical appliances.

[0003] Most existing electricity meters with overload protection circuit breakers lack a limit mechanism for the circuit breaker handle. This makes it easy for accidental circuit breaker activation during system maintenance when a circuit malfunctions, potentially causing injury to maintenance personnel. This invention designs an integrated mechanism for electricity meters with overload protection to solve the above problems. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-4 An integrated mechanism for an electricity meter with overload protection, comprising: The overload protection mechanism body 1 has a fixing plate 2 connected to both sides of the overload protection mechanism body 1 by screws. One end of the overload protection mechanism body 1 is provided with a toggle switch 3. A limit rod 4 is fixedly connected through and fixed to one side of the toggle switch 3. Limit arc grooves 5 and moving grooves 6 are opened on opposite sides of the fixing plate 2. A moving block 7 is slidably connected to the inner cavity of the moving groove 6. A limit mechanism 8 is provided on one side of the fixing plate 2. A stop block 9 is fixedly connected to one end of the moving block 7. A guide slope 10 is provided on the top edge of the stop block 9. A guide rod 11 is symmetrically connected to the inner cavity of the moving groove 6. A spring 12 is provided on the outer ring of the guide rod 11. A linkage groove 13 is symmetrically opened on one side of the fixing plate 2. A linkage block 14 is slidably connected to the inner cavity of the linkage groove 13. An L-shaped control plate 15 is fixedly connected to one side of the linkage block 14.

[0017] Both sides of the limiting rod 4 are located in the limiting arc groove 5 in the fixed plate 2, and the moving groove 6 is connected to the inner cavity of the limiting arc groove 5.

[0018] The stop block 9 extends into the inner cavity of the limiting arc groove 5 and is slidably connected to the fixed plate 2. The guide rod 11 extends into the moving block 7 and the two are slidably connected. When the stop block 9 extends into the inner cavity of the limiting arc groove 5, the spring 12 is in a compressed state.

[0019] The inner cavity of the linkage groove 13 is connected to the inner cavity of the moving groove 6, and the linkage block 14 is fixedly connected to the moving block 7.

[0020] In this embodiment of the utility model, when a fault occurs and the circuit needs to be disconnected through the overload protection mechanism body 1, the toggle switch 3 is turned downwards. During this process, in conjunction with the guide ramp 10, the stop block 9 and the moving block 7 move into the inner cavity of the moving groove 6, and in conjunction with the guide rod 11, the compression spring 12 is stabilized. When the limit rod 4 inside the toggle switch 3 rotates to the bottom of the limit arc groove 5, the L-shaped control plate 15 will not be limited by the limit mechanism 8. Under the action of the spring force of the spring 12, the moving block 7 and the stop block 9 are reset, and the stop block 9 is used to block the limit rod 4, thus preventing accidental contact that could cause the toggle switch 3 to rotate upwards and connect the circuit, which could cause injury to personnel. This ensures the safety of circuit maintenance and repair processes. Please refer to Figure 1 and Figure 5 The limiting mechanism 8 includes a U-shaped limiting frame 801 fixedly connected to one side of the fixed plate 2, an L-shaped control plate 15 located in the inner cavity of the U-shaped limiting frame 801 and the two are slidably connected, the U-shaped limiting frame 801 is symmetrically provided with a movable groove 802 at one end facing the L-shaped control plate 15, an L-shaped locking plate 803 is slidably connected to the inner cavity of the movable groove 802, and the L-shaped control plate 15 is symmetrically provided with an L-shaped locking groove 805 at one end facing the movable groove 802.

[0021] One end edge of the L-shaped plate 803 is provided with a guide slope 804. The top of the L-shaped plate 803 is fixedly connected to a control post 806. The top of the control post 806 is fixedly connected to a control block 807. The inner wall of the movable groove 802 is provided with a control groove 809. The inner cavity of the control groove 809 is provided with a spring 808. The spring 808 is located on the outer ring of the control post 806.

[0022] In this embodiment of the utility model, when the circuit needs to be connected after maintenance and repair, and the L-shaped control plate 15 is used to move the stop 9 out of the limiting arc groove 5, the L-shaped control plate 15 contacts the U-shaped limiting frame 801. During this process, in conjunction with the guide ramp 804, the symmetrical L-shaped clamping plate 803 moves towards the center. At this time, the spring 808 in the control groove 809 is compressed. With the elastic force of the spring 808, the L-shaped clamping plate 803 will automatically enter the L-shaped clamping groove 805 in the L-shaped control plate 15. The position of the L-shaped control plate 15 can be fixed to limit the stop block 9 that moves out of the limiting arc groove 5, ensuring that the toggle switch 3 can rotate smoothly to connect the circuit. After the circuit is connected, the control block 807 is pressed by hand to squeeze the two control posts 806, so that the L-shaped card plate 803 moves in the middle, and the L-shaped control plate 15 can be released from the limit of the L-shaped card plate 803. Under the action of the spring 12, it will reset itself, so that the stop block 9 will reset itself, which is convenient for limiting the limit rod 4 after the circuit is broken.

[0023] When using this integrated energy meter mechanism with overload protection, after installing the overload protection mechanism body 1 in the required position and connecting the wiring, when a fault occurs and the circuit needs to be disconnected through the overload protection mechanism body 1, turn the toggle switch 3 downwards. During this process, in conjunction with the guide ramp 10, the stop block 9 and the moving block 7 move into the inner cavity of the moving groove 6, and in conjunction with the guide rod 11, stabilize and compress the spring 12. When the limit rod 4 inside the toggle switch 3 turns to the bottom of the limit arc groove 5, the L-shaped control plate 15 will not be limited by the limit mechanism 8, but will be stopped by the elastic force of the spring 12. When the moving block 7 and the stop block 9 are reset, the stop block 9 will block the limit rod 4 to prevent accidental contact that could cause the toggle switch 3 to rotate upwards and connect the circuit, thus ensuring the safety of the circuit maintenance and repair process. When the circuit needs to be connected after the circuit maintenance and repair is completed, the moving block 7 will move to the moving groove 6 through the L-shaped control board 15 in conjunction with the linkage block 14 in the linkage groove 13, thereby moving the stop block 9 out of the limit arc groove 5, thus releasing the stop block 9 from limiting the limit rod 4, allowing the toggle switch 3 to rotate upwards and connect the circuit, facilitating the connection of the circuit.

[0024] 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, the scope of which is defined by the appended claims and their equivalents.
