[0002] A circuit breaker refers to a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. In the prior art, in order to improve the operating safety performance of the explosion-proof box, a circuit breaker control device is installed in it, wherein the handles on the circuit breaker and the circuit breaker with leakage protection need to be fixed by a toggle assembly. When any one of the circuit breaker and the circuit breaker with leakage protection trips, the circuit breaker and the circuit breaker with leakage protection will be disconnected at the same time, thereby affecting the normal operation of other equipment. Therefore, it is necessary to provide an adaptive toggle assembly. Utility Model Content

[0003] In order to solve the problem that the above-mentioned conventional control device will cause the circuit breaker and the circuit breaker with leakage protection to trip simultaneously when either one of them trips, the utility model provides a toggle assembly for a circuit breaker control device. The specific technical solution is as follows:

[0004] A toggle assembly for a circuit breaker control device comprises a covering member and a toggle member, wherein the covering member is symmetrically provided with two covering arms along the length direction, and the toggle member is fixedly mounted on a side of the covering member away from the two covering arms, wherein a notch is provided on one side of one of the covering arms, and the two covering arms and the covering member form a first accommodating cavity with a U-shaped cross-section, the circuit breaker handle is embedded in the first accommodating cavity, and the covering member follows the circuit breaker handle to close and open the circuit breaker, and the single covering arm and the covering member on one side of the notch form a semi-enclosed second accommodating cavity, the leakage protector handle is embedded in the second accommodating cavity, and the covering member follows the leakage protector handle to close the circuit breaker.

[0005] In some embodiments, the two covering arms are provided with folded edges bent toward each other on one side away from the covering member.

[0006] In some embodiments, a sealing opening is provided on a side of the covering member in the length direction away from the notch portion.

[0007] In some embodiments, a connecting protrusion is provided on the side of the covering away from the first accommodating cavity, a threaded groove is provided on the connecting protrusion, a fixing screw is provided through the connecting protrusion, and the fixing screw passes through the connecting protrusion and the covering and is inserted into the first accommodating cavity.

[0008] In some embodiments, the toggle member is cylindrical.

[0009] In some embodiments, the axis of the toggle member is perpendicular to the outer surface of the covering member.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, in this solution, the two covering arms and the covering member form a first accommodating cavity with a U-shaped cross-section, and the circuit breaker handle is embedded in the first accommodating cavity; the single covering arm and the covering member on one side of the notch form a semi-enclosed second accommodating cavity, and the leakage protector handle is embedded in the second accommodating cavity. When the circuit breaker and the leakage protector need to be closed, the circuit breaker control device drives the toggle member to flip upward, and at this time, the toggle member drives the covering member and the circuit breaker handle and the leakage protector handle therein to flip upward; When the leakage protector is triggered, the leakage protector automatically trips, the leakage protector handle flips downward, causing the cover to flip downward, and the cover flipping downward causes the circuit breaker handle to flip downward; when the circuit breaker is triggered, the circuit breaker automatically trips, the circuit breaker handle flips downward, causing the cover to flip downward, and the leakage protector handle detaches from the notch of the covering arm. This design not only does not affect the use function of the circuit breaker with leakage protection, but also allows ordinary circuit breakers and circuit breakers with leakage protection to share a toggle component.

[0012] Second: This solution provides a connecting protrusion on the side of the cover away from the first accommodating cavity, and the connecting protrusion is provided with a threaded groove. A fixing screw is provided through the connecting protrusion, and the fixing screw passes through the connecting protrusion and the cover and is inserted into the first accommodating cavity. When the circuit breaker handle is inserted into the first accommodating cavity, the fixing screw can be rotated to embed it into the first accommodating cavity, so that the circuit breaker handle is pressed against the first accommodating cavity by using the fixing screw, thereby improving the matching stability between the cover and the circuit breaker handle.

[0028] like Figures 1 to 7 As shown, a toggle assembly for a circuit breaker control device includes a covering member 1 and a toggle member 2. The covering member 1 is symmetrically provided with two covering arms 11 along the length direction. The toggle member 2 is fixedly mounted on the covering member 1 on a side away from the two covering arms 11. A notch is provided on one side of one of the covering arms 11. The two covering arms 11 and the covering member 1 form a first accommodating cavity 3 with a U-shaped cross section. The circuit breaker handle is embedded in the first accommodating cavity 3. The covering member 1 follows the circuit breaker handle to close and open the switch. The single covering arm 11 on the side of the notch and the covering member 1 A semi-enclosed second accommodating cavity 4 is formed, and the leakage protector handle is embedded in the second accommodating cavity 4. The covering member 1 follows the leakage protector handle when closing. In this solution, the circuit breaker and the leakage protector are arranged side by side, the circuit breaker handle is embedded in the first accommodating cavity 3, and the leakage protector handle is embedded in the second accommodating cavity 4. The notch of the covering arm 11 is located at the upper end of the leakage protector handle. When the covering member 1 is flipped upward, it can drive the leakage protector handle to move upward. When the covering member 1 is flipped downward, the leakage protector handle can be detached from the notch of the covering arm 11.

[0029] like Figure 2 As shown, when the circuit breaker and the leakage protector need to be closed, the circuit breaker control device drives the toggle member 2 to flip upward, and the toggle member 2 drives the covering member 1 and the circuit breaker handle and the leakage protector handle therein to flip upward;

[0030] like Figure 1 As shown, when the leakage protector triggers protection, the leakage protector automatically trips, the leakage protector handle flips downward, driving the cover 1 to flip downward, and the cover 1 flips downward, driving the circuit breaker handle to flip downward;

[0031] like Figure 3 As shown, when the circuit breaker triggers protection, the circuit breaker automatically trips, the circuit breaker handle flips downward, and drives the covering member 1 to flip downward. At this time, the leakage protector handle is separated from the notch of the covering arm 11.

[0032] Optionally, multiple circuit breakers can be provided in this solution, and multiple circuit breakers can be arranged side by side, and the handles of multiple circuit breakers can be simultaneously embedded in the first accommodating cavity 3 to complete the assembly, thereby improving the adaptability of this application.

[0033] In some embodiments, the two covering arms 11 are provided with folded edges 111 bent toward each other on the side away from the covering member 1, so as to improve the covering fit effect of the covering arms 11 on the circuit breaker handle, thereby allowing the covering member 1 to follow and drive the circuit breaker and the leakage protector to perform opening and closing actions.

[0034] In some embodiments, a connecting protrusion 14 is provided on the side of the covering 1 away from the first accommodating cavity 3, and a threaded groove is provided on the connecting protrusion 14. A fixing screw 15 is provided through the connecting protrusion 14, and the fixing screw 15 passes through the connecting protrusion 14 and the covering 1 and is inserted into the first accommodating cavity 3. When the circuit breaker handle is inserted into the first accommodating cavity 3, the fixing screw 15 can be rotated to embed it into the first accommodating cavity 3, so that the fixing screw 15 is used to tighten the circuit breaker handle to the first accommodating cavity 3, thereby improving the matching stability between the covering 1 and the circuit breaker handle.

[0035] In some embodiments, the cross-section of the connecting protrusion 14 is in the shape of a U-shape and is mounted on the covering member 1, forming a rectangular cavity between the connecting protrusion 14 and the covering member 1, thereby ensuring that the connecting protrusion 14 has a certain deformation space when tightened. When the fixing screw 15 is pressed against the circuit breaker handle, the connecting protrusion 14 bends and generates a resistance elastic force, thereby improving the resistance effect between the fixing screw 15 and the circuit breaker handle.

[0036] During the assembly process of the limiter 13, the circuit breaker and the leakage protector are first arranged side by side in sequence, and then the handles on the circuit breaker and the leakage protector are set on the same straight line. Then the covering member 1 is inserted into the handles of the circuit breaker and the leakage protector in turn, and then the fixing screw 15 is screwed into the connecting protrusion 14, and the circuit breaker handle in the first accommodating cavity 3 is gradually tightened. When disassembly is required, the fixing screw 15 is rotated in the opposite direction to separate the circuit breaker handle from the fixing screw 15, and then the covering member 1 is slid out from the circuit breaker handle and the leakage protector handle.

[0037] In some embodiments, the toggle member 2 is cylindrical, so as to improve the fit between the toggle assembly and the circuit breaker control device, allowing the circuit breaker control device to more smoothly control the toggle assembly to drive the circuit breaker and the leakage protector to open and close.

[0038] In some embodiments, the axis of the toggle member 2 is perpendicular to the outer surface of the covering member 1 , thereby improving the matching strength between the toggle member 2 and the covering member 1 .

[0039] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the claims of the present invention.
