[0036] Example 1:

[0037] Reference Figures 1-9 ​The utility model discloses an embodiment provides a kind of opening and closing device of pole switch, for control the opening and closing of multiple pole 100, including shell 1, sliding rod 2, crankshaft 3 and connecting rod 4.Crankshaft 3 is horizontally oriented and rotationally connected in shell 1, sliding rod 2 is set one by one with pole 100, and vertically oriented sliding connection is in the top wall of shell 1, the upper end of sliding rod 2 is fixedly connected the separation sleeve of pole 100, the lower end of sliding rod 2 extends to shell 1, crankshaft 3 has multiple crank parts 301 on it, connecting rod 4 is set to multiple, and the two ends of connecting rod 4 are one by one correspondingly articulated crank part and the lower end of sliding rod 2, as articulated along Figure 2 The axis of articulation point of the two ends of connecting rod 4 is parallel to the axis of crank.The opening and closing device further includes driving mechanism 5, driving mechanism 5 can drive the swing of the limited position of crankshaft 3, to drive sliding rod 2 between upper limit position and lower limit position switching, in turn make pole 100 between closed state and separation state switching.

[0038] In the embodiment, shell 1 is as the basic support structure of entire device, and its internal space provides necessary installation and operating environment for each moving component.Crankshaft 3 is designed to be horizontally oriented, such as left and right extension, and is rotationally connected with shell 1 by bearing or other rotation connection mode, to ensure its stability and durability in the driving process.Crankshaft 3 is provided with multiple crank parts 301, and the design of these crank parts 301 enables crankshaft 3 to be converted into multiple driving power sources, to provide basis for subsequent movement of connecting rod 4 and sliding rod 2.

[0039] Sliding rod 2 is set one by one with pole 100 as the component connecting crankshaft 3 and pole 100, and is vertically oriented sliding connection on the top wall of shell 1, to ensure the fluency of movement.The upper end of sliding rod 2 is fixedly connected with the separation sleeve of pole 100, to ensure that when sliding rod 2 moves up and down, pole 100 can be directly driven to open or close operation.The lower end of sliding rod 2 extends to shell 1 and is connected with crank part 301 through connecting rod 4.

[0040] Driving mechanism 5 can drive the swing of the limited position of crankshaft 3, to drive sliding rod 2 between upper limit position and lower limit position switching through connecting rod 4.In this process, pole 100 also switches between closed state and separation state, to realize the accurate control of circuit on-off.

[0041] Compared with prior art, the opening and closing device in the embodiment realizes linkage control of multiple poles 100 through mechanical structure based on crank connecting rod principle, to greatly improve the reliability and convenience of pole 100 opening and closing control.Linkage control can ensure that pole 100 can be simultaneously switched to the required working state, to greatly improve the use reliability and on-off accuracy of pole 100 module.

When different models of the pole 100 have different requirements for the vertical displacement of the separation sleeve, the rotation angle of the crank can be adjusted to meet the requirements.

[0043] Embodiment 2:

[0044] With reference to Figures 1-11 In addition to having all the technical solutions of Embodiment 1, the embodiments of the utility model further have the following technical solutions:

[0045] The driving mechanism 5 includes a rotating shaft 51 and a transmission assembly 52. The rotating shaft 51 is rotationally connected to the housing 1 and extends into the housing 1. The transmission assembly 52 is drivingly connected to the rotating shaft 51 and the crank. The driving mechanism 5 further includes a rotating assembly 53. The rotating assembly 53 is drivingly connected to the rotating shaft 51 to drive the rotating shaft 51 to rotate.

[0046] In this embodiment, the driving mechanism 5 is responsible for driving the crankshaft 3 to swing, thereby achieving the opening and closing control of the sliding rod 2 and the pole 100. The rotating shaft 51 is rotationally connected to the housing 1 and extends into the housing 1. Such a design enables the rotating shaft 51 to flexibly receive driving force from the outside and transmit it to other components inside the housing 1. Specifically, the rotating shaft 51 can extend in the front-rear direction.

[0047] The transmission assembly 52 is responsible for converting the rotary motion on the rotating shaft 51 into the swinging motion of the crank portion 301. The transmission assembly 52 can be designed as a bevel gear transmission assembly to ensure the accuracy and reliability of the transmission.

[0048] The rotating assembly 53 is drivingly connected to the rotating shaft 51 to provide external driving force and drive the rotating shaft 51 to rotate. The rotating assembly 53 can be designed as a manually operated handle, an electrically driven motor, or other forms of driving devices, depending on the requirements of the actual application scenario. When the rotating assembly 53 is activated, it will in turn drive the crankshaft 3 to swing through the rotating shaft 51 and the transmission assembly 52, thereby achieving the opening and closing control of the sliding rod 2 and the pole 100.

[0049] Specifically, the rotating assembly 53 has a position holding function, for example, when it is set as a handle, the handle can be locked at the upper limit position and the lower limit position of the sliding rod 2, for example, through a latch passing through the handle and the shell 1. In actual operation, the user can drive the rotating shaft 51 to rotate by operating the rotating assembly 53. With the rotation of the rotating shaft 51, the transmission assembly 52 converts this rotating motion into the swing motion of the crank. The swing of the crank drives the movement of the connecting rod 4, and in turn drives the sliding rod 2 to slide up and down in the shell 1. When the sliding rod 2 slides to the upper limit position, the pole 100 is in the closed state. When the sliding rod 2 slides to the lower limit position, the pole 100 is in the separated state. Through such an operation mode, the user can conveniently realize accurate control of the opening and closing state of the pole 100.

[0050] Since the rotating shaft 51 is a component extending out of the shell 1, it is easier to seal the connection between the rotating shaft 51 and the shell 1, thereby facilitating the reliability of the internal components of the shell 1.

[0051] More specifically, referring to Figure 8 and Figure 9 , the rotation angle of the rotating shaft 51 is set within 90°.

[0052] Embodiment 3:

[0053] Referring to Figure 1 and Figure 3 , the embodiments of the utility model further have the following technical solutions in addition to all the technical solutions of the above-mentioned embodiment 2:

[0054] The rotating assembly 53 includes a servo motor, which is drivingly connected with the rotating shaft 51 to drive the rotating shaft 51 to rotate according to a predetermined angle.

[0055] In this embodiment, the servo motor serves as the power source of the entire driving mechanism 5 and is responsible for providing stable and controllable driving force. It realizes accurate angle control through driving connection with the rotating shaft 51. The servo motor has extremely high positioning accuracy and repeat positioning accuracy, which can meet the demand of complex control tasks.

[0056] The servo motor is connected with the rotating shaft 51 through a reducer or direct connection. The reducer can reduce the output speed of the servo motor and increase the output torque at the same time to meet the demand of the rotating shaft 51 for driving torque.

[0057] The servo motor is provided with an encoder or an external position sensor to real-time feedback the actual angle information of the rotating shaft 51. Through a closed-loop control system, accurate control of the angle of the rotating shaft 51 is realized.

[0058] The advanced control algorithm, such as PID control and fuzzy control, is adopted to accurately control the servo motor. According to the preset angle instruction, the system calculates and outputs the corresponding control signal to drive the servo motor to operate according to the predetermined angle, so that the pole 100 can be switched to the corresponding lower limit position and upper limit position stably, efficiently and quickly.

[0059] The opening and closing device further comprises a power supply module for supplying power to the servo motor, and the power can come from a rechargeable battery which can be charged by solar energy and the like. The opening and closing device further comprises a controller connected in communication and a cloud end. The controller is connected with the servo motor in control, and the cloud end is responsible for issuing control instructions to the controller. The controller is used to control the servo motor to operate according to the predetermined angle, so as to realize remote control of the opening and closing operation, and further improve the convenience of the opening and closing operation.

[0060] Embodiment 4:

[0061] With reference to Figures 1-11 In addition to the above-mentioned embodiment 2, the embodiments of the utility model further have the following technical solutions:

[0062] The rotating assembly 53 comprises a gear 531 and a rack 532. The rack 532 is horizontally slidably connected to the outer wall of the shell 1, and the gear 531 is fixedly connected to one end of the rotating shaft 51 outside the shell 1. The rack 532 and the gear 531 are in engagement. The rack 532 is provided with a pushing part to drive the rack 532 to slide. The driving mechanism 5 further comprises an elastic release assembly 54. The elastic release assembly 54 comprises a first spring 541 and a clamping mechanism 542. The shell 1 extends a first spring seat 101, and the rack 532 extends a second spring seat 501. The two ends of the first spring 541 are respectively abutted on the first spring seat 101 and the second spring seat 501. When the sliding rod 2 is in the upper limit position, the first spring seat 101 is closer to the second spring seat 501, so that the first spring 541 is compressed to store power and provide the rack 532 with elastic force to drive the gear 531 to rotate. The clamping mechanism 542 clamps the second spring seat 501. When the clamping mechanism 542 releases the second spring seat 501, the second spring seat 501 slides away from the first spring seat 101, so that the sliding rod 2 is switched from the upper limit position to the lower limit position.

[0063] In this embodiment, the gear 531 is fixedly connected to one end of the rotating shaft 51 outside the shell 1, and the rack 532 is horizontally slidably connected to the outer wall of the shell 1 and is in engagement with the gear 531. This design allows the user to manually or mechanically push the rack 532, and then drive the rotating shaft 51 to rotate through the gear 531. The pushing part on the rack 532 provides an intuitive operation interface for the user, which is convenient to exert force.

[0064] When the user needs to operate the pole 100, the rack 532 can be slid by pulling the pull part on the rack 532. The sliding of the rack 532 drives the gear 531 meshed with the rack 532 to rotate, and then drives the crank to swing through the transmission assembly 52, so as to realize the opening and closing control of the sliding rod 2 and the pole 100.

[0065] The elastic release assembly 54 includes a first spring 541 and a clamping mechanism 542. The first spring seat 101 extends from the shell 1, and the second spring seat 501 extends from the rack 532. The two ends of the first spring 541 abut on the two spring seats respectively, forming a spring return system. The first spring seat 101 is a component fixed on the shell 1, and the second spring seat 501 is a component fixed on the rack 532.

[0066] When the sliding rod 2 is in the upper limit position, that is, the pole 100 is in the closed state, the first spring seat 101 is closer to the second spring seat 501, so that the first spring 541 is compressed to store energy. At this time, the clamping mechanism 542 clamps the second spring seat 501 to prevent the rack 532 from sliding by the spring force, so as to maintain the closed state of the pole 100.

[0067] When the user needs to disconnect the pole 100, the clamping action of the clamping mechanism 542 needs to be disabled, and then the rack 532 will slide and drive the gear 531 to rotate at a certain angle under the action of the elastic force of the first spring 541, until the sliding rod 2 reaches the lower limit position, that is, the pole 100 is in the separated state.

[0068] When the user needs to close the pole 100 again, the rack 532 can be slid in the reverse direction manually or by mechanical means. With the sliding of the rack 532, the gear 531 will rotate in the reverse direction, and the crank will be driven to swing in the reverse direction through the transmission assembly 52, so that the sliding rod 2 gradually moves upward. In this process, the first spring 541 will be compressed again to store energy, until the second spring seat 501 is clamped by the clamping mechanism 542 again, to prepare for the next operation.

[0069] The driving mechanism 5 in the embodiment is in the form of a machine, and the design of the first spring 541 storing energy can ensure that the device quickly and efficiently switches the pole 100 from the self-closed state to the separated state, and improves the breaking speed and reliability of the pole 100. The components of the driving mechanism 5 can be made of insulating materials to improve safety.

[0070] The elastic release assembly 54 further comprises a crossbar 543, one end of the crossbar 543 is fixedly connected to the first spring seat 101, the other end of the crossbar 543 penetrates through the second spring seat 501 and is in axial sliding connection with the second spring seat 501, the first spring 541 is circumferentially sleeved outside the crossbar 543, after the crossbar 543 is matched with the first spring seat 101, the running track of the rack 532 can be better limited, the rack 532 can stably and accurately slide along the length direction of the rack 532, and the operation reliability of the driving mechanism 5 is improved.

[0071] Embodiment 5:

[0072] With reference to Figures 1-11 In addition to all the technical solutions of the above-mentioned embodiment 4, the embodiments of the utility model further have the following technical solutions:

[0073] The opening and closing device further comprises an outer cover 6, the outer cover 6 is fixedly connected to the shell 1 and covers the main part of the elastic release assembly 54. The clamping mechanism 542 comprises a pressing rod 5421, the pressing rod 5421 is in sliding connection with the outer cover 6, one end of the pressing rod 5421 extends into the outer cover 6 and forms a limiting end X, the other end of the pressing rod 5421 extends out of the outer cover 6 and forms a pressing end Y. When the pressing rod 5421 axially slides, the limiting end X can be switched between the clamping position of clamping the second spring seat 501 and the release position of releasing the second spring seat 501. The clamping mechanism 542 further comprises a reset member 5422 for providing the pressing rod 5421 with a reset force from the release position to the clamping position. The reset member 5422 is a second spring sleeved on the pressing rod 5421, and the two ends of the second spring abut against the outer wall of the outer cover 6 and the pressing end Y respectively.

[0074] In the embodiment, the outer cover 6 is fixedly connected to the shell 1, which mainly covers and protects the elastic release assembly 54 and prevents it from being disturbed or damaged by the external environment. At the same time, the outer cover 6 also provides a stable mounting platform for the clamping mechanism 542. The pressing rod 5421 is in sliding connection with the outer cover 6, one end of the pressing rod 5421 extends into the outer cover 6 and forms a limiting end X for clamping or releasing the second spring seat 501. The other end of the pressing rod 5421 extends out of the outer cover 6 and forms a pressing end Y for user operation.

[0075] When the limiting end X of the pressing rod 5421 is in the clamping position of clamping the second spring seat 501, it can effectively prevent the rack 532 from sliding by itself under the action of the spring force, thereby maintaining the closed state of the pole 100. When the user needs to change the state of the pole 100, the pressing end Y can be pressed to make the pressing rod 5421 axially slide, so that the limiting end X is separated from the second spring seat 501 and switched to the release position of releasing the second spring seat 501.

[0076] The reset member 5422, i.e., the second spring sleeve, is arranged on the pressing rod 5421, and the two ends thereof abut against the outer wall of the outer cover 6 and the pressing end Y respectively. When the user releases the pressing end Y, the second spring pushes the pressing rod 5421 to automatically reset to the clamping position, so as to prepare for the next operation. This design not only improves the convenience of operation, but also ensures that the clamping mechanism 542 can maintain a stable state when no one operates.

[0077] When the user needs to disconnect the pole 100, the pressing end Y is first pressed to make the pressing rod 5421 slide to the release position, at this time, the limiting end X releases the second spring seat 501, allowing the rack 532 to slide under the action of the spring force and drive the gear 531 to rotate. With the sliding of the rack 532, the pole 100 gradually switches to the separated state.

[0078] When the user needs to close the pole 100, the rack 532 can be reversely slid by manual or mechanical means. With the sliding of the rack 532, the gear 531 reversely rotates and drives the crank to swing, so that the sliding rod 2 gradually moves upward to the closed position, and the limiting end X of the pressing rod 5421 also clamps the second spring seat 501 again.

[0079] By introducing the outer cover 6 and the clamping mechanism 542, the opening and closing device not only realizes accurate control of the opening and closing state of the pole 100, but also improves the safety and convenience of operation. The protective effect of the outer cover 6 ensures that the elastic release assembly 54 is not disturbed by the external environment. The introduction of the clamping mechanism 542 provides a visual and easy-to-operate control interface for the user. This design not only improves the overall performance of the device, but also brings a more comfortable and reliable user experience.

[0080] Specifically, the outer cover 6 is also provided with a split and combination identifier to indicate the working state of the pole 100 to the staff.

[0081] The outer cover 6 is provided with a giving slot, and the actuating part on the rack 532 extends out of the giving slot, so as to facilitate the relevant personnel to slide the rack 532.
