[0033] Specifically, the present application provides a push-to-unlock device 100, which is composed of a rotating portion 110 and a locking portion 120 connected to each other. The rotating portion 110 is used to be inserted into the circuit breaker base 210, and the locking portion 120 is used to be inserted into the circuit breaker body 220, so that the circuit breaker body 220 and the circuit breaker base 210 are connected by the rotating portion 110 and the locking portion 120 of the push-to-unlock device 100;

During the pressing process, the circuit breaker body 220 simultaneously drives the rotating portion 110 and the locking portion 120 to rotate; the rotating portion 110 is pressed along the setting direction of the circuit breaker base 210 and the circuit breaker body 220 until it is completely inserted into the circuit breaker base 210, and at the same time rotated to a preset angle to be engaged with the circuit breaker base 210. At this time, the circuit breaker base 210 and the circuit breaker body 220 are connected as a whole.

[0035] It should be noted that, in the embodiment of the present application, the circuit breaker body 220 is moved closer to the circuit breaker base 210 by pressing, and the push-to-release device 100 is rotated while pressing, so that the rotating portion 110 of the push-to-release device 100 is engaged with the circuit breaker base 210, thereby connecting the circuit breaker base 210 to the circuit breaker body 220. Similarly, Figure 3 As shown, after the circuit breaker base 210 is connected to the circuit breaker body 220, the push-to-unlock device 100 is pressed to unlock and separate the rotating portion 110 of the push-to-unlock device 100 from the circuit breaker base 210, and the circuit breaker base 210 is separated from the circuit breaker body 220. Preferably, the push-to-unlock device 100 is rotated to 90 degrees in a clockwise or counterclockwise direction to achieve locking or separation with the circuit breaker base 210. Of course, the specific rotation direction and rotation angle can also be adjusted and changed according to actual needs, and the present application does not impose any restrictions on this.

[0036] The push-to-unlock device 100 provided in the present application comprises a rotating part 110 and a locking part 120 connected to each other, wherein the rotating part 110 is inserted into the circuit breaker base 210, and the locking part 120 is inserted into the circuit breaker body 220 along the extension direction of the rotating part 110; the locking part 120 and the rotating part 110 are pressed along the extension direction of the rotating part 110, and the locking part 120 and the rotating part 110 are driven to rotate by a preset angle at the same time, so that the rotating part 110 is inserted into the circuit breaker base 210. The push-to-unlock device 100 obtained by the above design can be rotated while being pressed to enable the circuit breaker body 220 and the circuit breaker base 210 to be assembled and disassembled, and its connection stability is strong, and the assembly and disassembly process is simple.

[0037] Furthermore, if Figure 1 As shown, the rotating part 110 includes a rotating column 111 and a sliding groove 112, and the sliding groove 112 is arranged on the outer wall of the rotating column 111 along the pressing direction of the rotating column 111; the locking part 120 and the rotating part 110 are pressed along the extending direction of the rotating part 110, and the locking part 120 and the rotating part 110 are driven to rotate a preset angle, so that the rotating column 111 is inserted into the circuit breaker base 210, and the rotating column 111 is engaged with the circuit breaker base 210 through the sliding groove 112.

[0038] The sliding groove 112 is formed by connecting a plurality of V-shaped grooves in sequence, and the sliding groove 112 is disposed around the outer wall of the rotating column 111 .

[0039] Specifically, the rotating part 110 includes a rotating column 111, which is cylindrical so as to be able to smoothly rotate inside the circuit breaker base 210; the outer wall of the rotating column 111 is provided with a sliding groove 112, which is formed by connecting a plurality of V-shaped grooves in sequence along the pressing direction of the rotating column 111 and surrounds the outer wall of the rotating column 111, so that the left and right sides of the sliding groove 112 are connected;

[0040] The shape of the sliding groove 112 is adapted to the rotation trajectory of the rotating part 110. The sliding groove 112 is roughly formed by connecting a plurality of V-shaped grooves in sequence, so that it has a plurality of inflection points, and the sliding grooves 112 on both sides of the inflection points are in opposite directions; when the rotating column 111 is inserted into the circuit breaker base 210, the rotating column 111 can be engaged with the circuit breaker base 210 through the sliding groove 112; therefore, when the push-to-unlock device 100 is pressed toward a side close to the circuit breaker base 210 while rotating, it can move along the sliding groove 112 until it is pressed and slides to the inflection point of the sliding groove 112, and cannot be rotated further. At this time, the rotating column 111 is engaged with the circuit breaker base 210, so that the circuit breaker base 210 is connected to the circuit breaker body 220.

[0041] By such a setting, the push-to-release device 100 can be locked with the circuit breaker base 210 by rotating to a preset angle while being pressed, making the assembly and disassembly process simpler and more efficient; at the same time, the setting of multiple inflection points also makes the locking stability of the push-to-release device 100 and the circuit breaker base 210 stronger.

[0042] Furthermore, if Figure 1 As shown, the locking portion 120 includes a connecting rod 121 and a locking rod 122, one end of the connecting rod 121 is connected to the end of the rotating column 111, and the other end is connected to the middle of the locking rod 122; the locking rod 122 is perpendicular to the connecting rod 121, and the locking rod 122 is used to be inserted into the inside of the circuit breaker body 220.

Through such a setting, the circuit breaker body 220 can drive the connecting rod 121 and the locking portion 120 to be pressed toward the side close to the circuit breaker base 210 through the locking rod 122, and can drive the connecting rod 121 and the locking portion 120 to rotate through the locking rod 122, further improving the reliability and efficiency of the loading and unloading process of the circuit breaker body 220 and the circuit breaker base 210.

[0044] In an implementation scheme of the present application, the push-to-unlock device 100 further includes an elastic member 130 , one end of the elastic member 130 abuts against one end of the rotating column 111 away from the locking portion 120 , and the other end abuts against the inside of the circuit breaker base 210 .

[0045] Specifically, Figure 2 and Figure 3 As shown, the push-to-unlock device 100 further includes an elastic member 130, one end of which abuts against one end of the rotating column 111 away from the locking portion 120, and the other end abuts against the inside of the circuit breaker base 210. Preferably, a mounting groove may be recessed at one end of the rotating column 111 facing the elastic member 130, and one end of the elastic member 130 may extend into the mounting groove to further stably connect with the rotating column 111; of course, the end of the rotating column 111 facing the elastic member 130 may also be a plane, and one end of the elastic member 130 may abut against the end of the rotating column 111, and the present application does not impose any limitation on this.

[0046] Preferably, the elastic member 130 is a spring. Of course, a spring sheet with a certain curvature may also be selected. By setting the elastic member 130, when the push-to-unlock device 100 is pressed and rotated in a direction close to the circuit breaker base 210, it can be subjected to a certain buffering force of the elastic member 130, thereby further improving the reliability and stability of the connection process between the circuit breaker base 210 and the circuit breaker body 220.

[0047] On the other hand, an embodiment of the present application further provides a circuit breaker 200, including a circuit breaker base 210, a circuit breaker body 220 and a push-to-unlock device 100, wherein the rotating portion 110 of the push-to-unlock device 100 is inserted into the circuit breaker base 210, and the locking portion 120 is inserted into the circuit breaker body 220; the locking portion 120 and the rotating portion 110 are pressed along the extension direction of the rotating portion 110, and the locking portion 120 and the rotating portion 110 are driven to rotate by a preset angle so that the rotating portion 110 is inserted into the circuit breaker base 210.

[0049] like Figure 2 As shown, after the rotating part 110 and the locking part 120 are respectively inserted into the circuit breaker base 210 and the body, the circuit breaker body 220 is pressed toward the circuit breaker base 210 along the extension direction of the rotating part 110. During the pressing process, the circuit breaker body 220 drives the rotating part 110 and the locking part 120 of the press-unlocking device 100 to rotate; the rotating part 110 is pressed along the setting direction of the circuit breaker base 210 and the circuit breaker body 220 to be inserted into the circuit breaker base 210, and at the same time rotated to a preset angle to be engaged with the circuit breaker base 210, at which time the circuit breaker base 210 and the circuit breaker body 220 are connected as a whole.
