DETAILED DESCRIPTION

[0016] The utility model is further described in detail below through specific implementation methods:

[0017] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a circuit breaker opening and closing adjustment device, comprising an operating rod 1 and a connector 2 connected to a connecting end of the operating rod 1, and also comprising a fixed clamping jaw 3, a movable clamping jaw 4 and an adjustment assembly 5;

[0018] The fixed jaw 3 is fixedly connected to the connector 2, one end of the movable jaw 4 is rotatably connected to the connector 2 and cooperates with the fixed jaw 3, and the adjustment component 5 is connected to the movable jaw 4 and is used to control the rotation of the movable jaw 4.

[0019] In this embodiment:

[0020] Specifically, the fixed jaw 3 and the movable jaw 4 are arranged facing each other, one end of the fixed jaw 3 is fixedly connected to the side wall of the connecting head 2, and one end of the fixed jaw 3 is movably arranged in a mounting groove 6 opened on the side wall of the connecting head 2. The middle part of the fixed jaw 3 is rotatably connected to the mounting groove 6 through a rotating shaft, and the end of the fixed jaw 3 placed in the mounting groove 6 is connected to the adjustment component 5.

[0021] When not in use, a sufficient insertion spacing is formed between the fixed clamping jaw 3 and the movable clamping jaw 4, so that the opening and closing of the circuit breaker switch can be moved from the insertion spacing to between the fixed clamping jaw 3 and the movable clamping jaw 4. Then, the movable clamping jaw 4 is rotated by adjusting the component 5 to cooperate with the fixed clamping jaw 3 to clamp and fix the opening and closing of the circuit breaker switch. At this time, the operating rod 1 is moved to complete the opening and closing of the circuit breaker switch; after completion, the movable clamping jaw 4 is reversely rotated and reset by adjusting the component 5, and the movable clamping jaw 4 and the fixed clamping jaw 3 are separated from the opening and closing of the circuit breaker switch. At this time, the opening and closing of the circuit breaker switch can be moved out from the insertion spacing.

[0022] In order to better understand this solution, the structure of the adjustment component 5 and the like will be optimized below.

[0023] like Figure 2 and Figure 3 As shown, according to another embodiment of the utility model, a circuit breaker opening and closing adjustment device, wherein the adjustment component 5 includes a control part 51 and a traction part 52, the control part 51 is arranged at the gripping end of the operating rod 1, and the traction part 52 is connected between the control part 51 and the moving clamp 4.

[0024] When in use, the movable clamping jaw 4 is controlled to rotate by adjusting the control part 51 and transmitting through the traction part 52, so as to achieve the purpose of controlling the clamping state of the movable clamping jaw 4 and the fixed clamping jaw 3 on the opening and closing of the circuit breaker switch. The control part 51 is arranged at the gripping end of the operating rod 1, which is convenient for the user to operate.

[0025] like Figure 3 As shown, according to another embodiment of the utility model, a circuit breaker opening and closing adjustment device, wherein the control part 51 includes a control rod 511, the control rod 511 is distributed along the axial direction of the holding end of the operating rod 1, and the middle part of the control rod 511 is rotatably connected to the outer wall of the holding end of the operating rod 1, one end of the control rod 511 is connected to the outer wall of the holding end of the operating rod 1 through an elastic support member 512, and the other end of the control rod 511 is connected to the traction part 52.

[0026] The elastic support member 512 can be a spring, and the middle part of the control rod 511 is rotatably connected to the outer wall of the gripping end of the operating rod 1 through a support rod; the elastic support member 512 makes the end of the control rod 511 connected to the traction part 52 abut against the outer wall of the gripping end of the operating rod 1 when not in use, at this time, the fixed clamping jaw 3 and the movable clamping jaw 4 are in an open state, and a sufficient insertion distance is formed between the fixed clamping jaw 3 and the movable clamping jaw 4; when it is necessary to clamp the opening and closing of the circuit breaker switch, the control rod 511 is pressed away from the end connected to the traction part 52, the elastic support member 512 is contracted, and the control rod 511 is away from the traction part 52 The connected end rotates in the direction away from the operating rod 1, and the moving jaw 4 is driven to rotate in the direction close to the fixed jaw 3 through the traction part 52, and the fixed jaw 3 cooperates with the moving jaw 4 to clamp the opening and closing of the circuit breaker switch; after completing the opening and closing of the circuit breaker switch, release the pressure on the control rod 511, and the elastic support member 512 resets the control rod 511, and the control rod 511 rotates away from the end connected to the traction part 52 toward the operating rod 1 until they are against each other, and the moving jaw 4 is driven to rotate in the direction away from the fixed jaw 3 through the traction part 52, and the fixed jaw 3 and the moving jaw 4 are released from clamping the opening and closing of the circuit breaker switch.

[0027] Here, the distance between the support rod and the operating end of the control rod 511 is smaller than the distance between the support rod and the other end of the control rod 511, so that the arc length of the rotation of the operating end of the control rod 511 pressed by the user is smaller than the arc length of the rotation of the other end of the control rod 511, and the movable clamping jaw 4 can rotate quickly and reasonably to cooperate with the fixed clamping jaw 3.

[0028] like Figure 2 and Figure 3 As shown, according to another embodiment of the utility model, a circuit breaker opening and closing adjustment device is provided, wherein a mounting through hole 7 is opened in the operating rod 1 along its axial direction, and a connecting hole 8 connected to the mounting through hole 7 is opened in the connecting head 2; the traction part 52 includes a traction rope 521, and the traction rope 521 is connected between the control part 51 and the dynamic clamping jaw 4 and can freely pass through the mounting through hole 7 and the connecting hole 8.

[0029] The connecting hole 8 is specifically connected between the installation groove 6 and the installation through hole 7; the installation through hole 7 and the connecting hole 8 provide space for the installation of the traction rope 521, and play a certain protective role for the traction rope 521. In the process of controlling and adjusting the operating rod 1, the traction rope 521 is used for transmission to control the rotation of the movable clamp 4.

[0030] In order to facilitate the disassembly of the operating rod 1 and the connecting head 2 and ensure a stable connection between the operating rod 1 and the connecting head 2, the operating rod 1 is threadedly connected to the connecting head 2 and the traction rope 521 includes a first rope segment 5211 and a second rope segment 5212; wherein, one end of the first rope segment 5211 is connected to the control part 51 and the first rope segment 5211 passes through the mounting hole 7; one end of the second rope segment 5212 is connected to the dynamic clamp 4 and the other end of the second rope segment 5212 passes through the connecting hole 8 and is detachably connected to the other end of the first rope segment 5211 through a hook 5214 structure.

[0031] Before the operating rod 1 and the connecting head 2 are connected, the first rope segment 5211 and the second rope segment 5212 are connected together through the hook 5214 structure, and then the operating rod 1 and the connecting head 2 can be connected; when the operating rod 1 and the connecting head 2 are separated, the connection between the first rope segment 5211 and the second rope segment 5212 is released through the hook 5214 structure, and then the operating rod 1 and the connecting head 2 are completely separated.

[0032] Among them, the hook 5214 structure includes a hanging ring 5213 and a hook 5214, the hanging ring 5213 is fixedly connected to the end of the second rope segment 5212 away from the dynamic clamp 4, the outer diameter of the hanging ring 5213 is larger than the aperture of the connecting hole 8 and smaller than the aperture of the installation through hole 7; the hook 5214 is fixedly connected to the end of the first rope segment 5211 away from the control part 51 and after the connection, the hook 5214 is hung on the hanging ring 5213.

[0033] Among them, the cooperation between the hanging ring 5213 and the hook 5214 is an existing structure. The outer diameter of the hanging ring 5213 is larger than the aperture of the connecting hole 8 and smaller than the aperture of the installation through hole 7 so that the second rope segment 5212 of the hanging ring 5213 will not move out of the connecting hole 8, which is beneficial to improve the installation efficiency when connecting the operating rod 1 and the connecting head 2.

[0034] In order to avoid limitation caused by the connection between the first rope segment 5211 and the second rope segment 5212 when the operating rod 1 and the connecting head 2 are connected or separated, the traction part 52 also includes an adjusting column 522, which is threadedly connected to the control part 51 and the traction rope 521 is wound around the adjusting column 522 at one end away from the dynamic clamp 4.

[0035] The adjusting column 522 is specifically connected to the end of the first rope segment 5211 away from the second rope segment 5212. Before the operating rod 1 and the connector 2 are separated, the adjusting column 522 is rotated to release the first rope segment 5211 to increase the usable length of the first rope segment 5211, and then the operating rod 1 and the connector 2 can be separated, and then the hook 5214 is disconnected from the hanging ring 5213, and the operating rod 1 and the connector 2 are completely separated. Before the operating rod 1 and the connector 2 are connected, the hook 5214 is first hung on the hanging ring 5213, and then the operating rod 1 and the connector 2 are connected, and then the adjusting column 522 is reversely rotated to make the first rope segment 5211 and the second rope segment 5212 in a tensioned state, so that the dynamic clamp 4 can react quickly when the control rod 511 is adjusted.

[0036] The adjusting column 522 has a limiting hole, and the traction rope 521 is wound around the adjusting column 522 and then freely passes through the limiting hole and then through the installation through hole 7. Specifically, one end of the first rope segment 5211 away from the second rope segment 5212 is wound around the adjusting column 522 and then freely passes through the limiting hole and then through the installation through hole 7, so as to stably connect the first rope segment 5211 to the adjusting column 522. Here, the adjusting column 522 can be a bolt, one end of which is threadedly connected to the control rod 511, and the other end of the bolt is a large head and the limiting hole is opened at this end of the bolt.

[0037] like Figure 1 As shown, according to another embodiment of the utility model, in the circuit breaker opening and closing adjustment device, elastic gaskets 9 are arranged on the clamping surfaces of the fixed clamping jaws 3 and the movable clamping jaws 4. During clamping, the elastic gaskets 9 and the opening and closing of the circuit breaker switch are softly clamped to improve the service life.

[0038] Among them, because the opening and closing shape of the circuit breaker switch is cylindrical, the fixed clamping jaw 3 and the movable clamping jaw 4 are designed to be arc-shaped to improve the clamping stability; when the opening and closing shape of the circuit breaker switch is adjusted, the shapes of the fixed clamping jaw 3 and the movable clamping jaw 4 can be adjusted for applicability.

[0039] In this solution, when the operating rod 1 and the connecting head 2 are connected: first hang the hook 5214 on the hanging ring 5213, then connect the operating rod 1 and the connecting head 2, and then rotate the adjustment column 522 to put the first rope segment 5211 and the second rope segment 5212 in a tensioned state.

[0040] When in use: move the operating rod 1 to place the opening and closing switch of the circuit breaker switch between the fixed clamping jaw 3 and the movable clamping jaw 4, then press the operating end of the control rod 511 to rotate the movable clamping jaw 4 towards the fixed clamping jaw 3, the movable clamping jaw 4 cooperates with the fixed clamping jaw 3 to clamp the opening and closing switch of the circuit breaker switch, and then move the operating rod 1 to complete the opening and closing of the circuit breaker switch; after completion, release the pressure on the operating end of the control rod 511, and the elastic support member 512 makes the control rod 511 rotate in the opposite direction, thereby driving the movable clamping jaw 4 to rotate in the opposite direction, and the movable clamping jaw 4 and the fixed clamping jaw 3 are separated from the opening and closing switch of the circuit breaker switch, and the opening and closing switch of the circuit breaker switch can be moved out from between the movable clamping jaw 4 and the fixed clamping jaw 3.

[0041] When the operating rod 1 and the connecting head 2 are separated: rotate the adjusting column 522 to release the first rope segment 5211 to increase the usable length of the first rope segment 5211, and then the operating rod 1 and the connecting head 2 can be separated, and then the hook 5214 is disconnected from the hanging ring 5213. At this time, the operating rod 1 and the connecting head 2 are completely separated.

[0042] When the first rope segment 5211 and the second rope segment 5212 are in a tensioned state, rotating the adjustment column 522 can also adjust the insertion spacing formed between the fixed clamping jaw 3 and the movable clamping jaw 4 .

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
