Description
Technical Field
[0001] This utility model relates to the field of triggering device technology, specifically to a position signal triggering device, an electric cabinet, and an electric drawer. Background Technology
[0002] Switches are commonly used components in industrial equipment, typically used in conjunction with signal triggering devices. In existing electric cabinets and drawers, microswitches are generally used as signal triggers. During use, the driver drives the slider to press the microswitch, triggering the output of a position signal. At this point, the operator can know that the slider has moved to the correct position and is ready to proceed to the next operation. However, because the microswitch has a spring, it generates elasticity when pressed, which can easily cause the trigger to bounce back. This results in the failure to form a detection state after the position signal is disconnected. In existing electric cabinets and drawers, the space for installing switches is limited, making it inconvenient to set up a structure that keeps the microswitch in the triggered state after the slider triggers the position signal. In this situation, the operator cannot determine the state of the microswitch and cannot complete the next operation. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a position signal triggering device, electric cabinet, and electric drawer, which can improve the problem that the existing signal triggering device cannot stably and continuously trigger the switch after it is in position.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning signal triggering device, an electric cabinet, and an electric drawer, comprising a platform, a trigger, a first switch, and a driver. The platform is provided with a slide groove and a slider. The driver can drive the slider to slide along the slide groove. The slide groove limits the slider. The trigger is movably disposed between the slide groove and the first switch. The slider moves to push the trigger into contact with the first switch. One side of the trigger abuts against the first switch, and the other side abuts against the slider. The slide groove limits the slider so that the slider can push the trigger to continuously abut against the first switch.
[0005] As a further improvement of this utility model, the trigger has an input terminal and an output terminal, the input terminal is connected to the output terminal, the input terminal is exposed on the sliding path in the slide groove when the first switch is not triggered, and the slider pushes the input terminal to drive the output terminal to move toward the first switch.
[0006] As a further improvement of this utility model, the trigger is connected to the platform via a rotating shaft.
[0007] As a further improvement of this utility model, the trigger is connected to the platform via a slide.
[0008] As a further improvement of this utility model, a second switch is provided on the platform. Both the first switch and the second switch are set at the corresponding positions of the slide groove. When the slider moves to the other side, it can act on the second switch. The first switch is a micro switch and the second switch is a micro switch.
[0009] As a further improvement of this utility model, the slide is a horizontal straight slide, the first switch is located below the slide, and the trigger is composed of two L-shaped arms, with the input end of the trigger located on the arm closer to the slide and the output end of the trigger located on the arm closer to the first switch.
[0010] This solution also provides an electric cabinet, including a cabinet body, wherein an arrival signal triggering device is provided inside the cabinet body. The arrival signal triggering device adopts the arrival signal triggering device described in any of the above-mentioned improved solutions, and the platform is connected to the cabinet body.
[0011] This solution also provides an electric drawer, including a drawer body, wherein an arrival signal triggering device is provided inside the drawer body, the arrival signal triggering device adopts the arrival signal triggering device described in any of the above improvements, and the platform is connected to the drawer body.
[0012] Compared with existing technologies, this utility model provides a position signal triggering device, an electric cabinet, and an electric drawer, which have the following advantages: This device, through the cooperation of a sliding groove on the platform and a slider, can limit and constrain the movement trajectory and stroke of the slider, reducing the offset during slider sliding, improving the smoothness of slider movement, and providing a stable structural foundation for signal triggering. The trigger is movably positioned between the slider and the first switch, abutting against both on its sides. The sliding of the slider drives the trigger to actuate, thereby triggering the first switch to complete the position signal acquisition and maintaining the position signal trigger state. This device has a compact structure, simple component configuration, is easy to assemble and maintain, and is suitable for conventional mechanical position detection scenarios, exhibiting good applicability.

[0015] As shown in the figure, in order to achieve the above objectives, this utility model provides a position signal triggering device 1, an electric cabinet, and an electric drawer. The position signal triggering device 1 can be installed on the electric cabinet or on the electric drawer, and the installation method can be bolt fixing.
[0016] This positioning signal triggering device 1 includes a platform 2, a trigger 3, a first switch 4, and a driver 12. The platform 2 is provided with a slide groove 5 and a slider 6. The driver 12 can drive the slider 6 to slide along the slide groove 5. The slide groove 5 limits the slider 6. The trigger 3 is movably disposed between the slide groove 5 and the first switch 4. The slider 6 pushes the trigger 3 to contact the first switch 4 by moving. One side of the trigger 3 abuts against the first switch 4, and the other side abuts against the slider 6. The slider 6 is limited by the slide groove 5 so that the slider 6 can push the trigger 3 to continuously abut against the first switch 4.
[0017] In this implementation, the first switch 4 can be fixedly connected to the platform 2 or fixedly installed at other positions corresponding to the slide 5. The platform 2 is provided with the slide 5 and the slider 6. The slider 6 is partially placed inside the slide 5 and forms a sliding connection with the slide 5. In this scheme, the sliding of the slider 6 is driven by the driver 12, which can be a lead screw and a motor. The slider 6 is connected to the lead screw, and the motor drives the lead screw to rotate, thereby moving the slider 6 along the lead screw. The inner wall of the slide 5 limits the sliding stroke of the slider 6. The trigger 3 is movably disposed in the area between the slide 5 and the first switch 4. In the initial state, one side of the trigger 3 is separated from the contact of the first switch 4, and the other side extends into the path of the slide 5. When the slider 6 slides along the slide 5 to the predetermined position, the slider 6 pushes the trigger 3, causing the side of the trigger 3 corresponding to the first switch 4 to move towards the first switch 4, thereby triggering the first switch 4. In the first embodiment, the trigger 3 is rotatably mounted on the platform 2 via a rotating shaft 9. One end of the trigger 3 protrudes from the sliding path in the groove 5, and the other end is used to abut against the first switch 4. The slider 6 pushes the trigger 3 to rotate around the rotating shaft 9, causing the end facing the first switch 4 to rotate towards the triggering part of the first switch 4 to press the first switch 4. In another embodiment, the trigger 3 is slidably mounted on the platform 2 via a sliding block. The slider 6 pushes the trigger 3 to move through the sliding block to cause the trigger 3 to touch the first switch 4. Both methods can trigger the first switch 4 when the slider 6 is in position. Since the groove 5 can limit the slider 6, it is not easy for the slider 6 to displace away from the first switch 4 after it slides into position. One side of the trigger 3 abuts against the first switch 4, and the other side abuts against the slider 6, so that the trigger 3 keeps triggering the first switch 4 continuously. The switch in this solution can be a micro switch.
[0018] As an improved specific implementation, the trigger 3 has an input terminal 7 and an output terminal 8. The input terminal 7 is connected to the output terminal 8. When the first switch 4 is not triggered, the input terminal 7 is exposed on the sliding path in the slide groove 5. The slider 6 pushes the input terminal 7 to drive the output terminal 8 to move toward the first switch 4.
[0019] In this implementation, the trigger 3 has an input terminal 7 and an output terminal 8, which are fixedly connected or integrally formed. When the first switch 4 is not triggered, the input terminal 7 is exposed on the sliding path in the groove 5, that is, the input terminal 7 extends into the movement path of the slider 6. The output terminal 8 is positioned opposite to the contact of the first switch 4. When the slider 6 slides along the groove 5 to the position where it contacts the input terminal 7, the continued movement of the slider 6 will push the input terminal 7, which in turn drives the output terminal 8 to move synchronously toward the first switch 4, thereby triggering the first switch 4. In this design, the trigger 3 can be designed as an L-shaped rod, where one end of the L-shaped rod is the input terminal 7, extending into the groove 5, and the other end is the output terminal 8, which can move toward the first switch 4. When slider 6 moves, it pushes the input end 7 of L-shaped rod. The L-shaped rod moves as a whole or rotates along the axis, causing output end 8 to trigger the first switch 4. After output end 8 triggers the first switch 4, slider 6 is in contact with input end 7 on the side facing input end 7. At this time, input end 7 is no longer exposed in slide groove 5, and input end 7 and the side wall of slide groove 5 are at the same horizontal line.
[0020] As an improved specific implementation, the trigger 3 is connected to the platform 2 via the rotating shaft 9.
[0021] In implementation, the trigger 3 is connected to the rotating shaft 9 and allowed to rotate around it. The trigger 3 functions as a lever, with its input end 7 located on one side of the rotating shaft 9 and extending into the slide groove 5, and its output end 8 located on the other side of the rotating shaft 9, used to abut against the contact of the first switch 4 after rotation. When the slider 6 moves along the slide groove 5 and pushes the input end 7, the trigger 3 rotates around the rotating shaft 9, and the output end 8 moves towards the first switch 4, thus pressing the first switch 4. The rotation of the rotating shaft 9 ensures smooth movement of the trigger 3 during rotation, and the travel distance between the input end 7 and the output end 8 can be adjusted by the lever arm length ratio. If it is necessary to reset the trigger 3, a reset spring can be used to reset the trigger 3 when it is not in contact with the slider 6.
[0022] As an improved specific implementation, the trigger 3 is connected to the platform 2 via a slide.
[0023] In implementation, the slide block can be slidably connected to the platform 2, with the trigger 3 mounted on it, forming a sliding fit between the slide block and the platform 2. Alternatively, the slide block can be fixedly mounted on the platform 2, with a linear guide groove or guide hole provided within it, and the trigger 3 slidably assembled within this guide groove. The trigger 3 is rod-shaped or block-shaped, with its input end 7 protruding from the slide groove 5 and its output end 8 facing the first switch 4. When the slider 6 pushes the input end 7, the trigger 3 slides linearly along the slide block, and the output end 8 approaches and presses the first switch 4. After the slider 6 retracts, the trigger 3 can be reset by using a return spring.
[0024] As an improved specific implementation, the platform 2 is provided with a second switch 11. The first switch 4 and the second switch 11 are both set at the positions of the slide groove 5. The slider 6 can act on the second switch 11 when it moves to the other side. The first switch 4 is a micro switch and the second switch 11 is a micro switch.
[0025] In implementation, a second switch 11 is also installed on the platform. Both the first switch 4 and the second switch 11 are installed corresponding to the positions of the slide groove 5, and are located on different sides of the slide groove 5 or at different positions along the length of the slide groove 5. After the slider 6 slides into position along the slide groove 5, at least one of the switches can be activated. The two switches can be set near the beginning and end of the slide groove 5, respectively. The slider 6 can only move to the trigger position in one direction within the slide groove 5, and cooperate with the corresponding trigger 3 to press the switch at that end, while the switch at the other end cannot be activated.
[0026] As an improved specific implementation, the slide 5 is a horizontal straight slide 5, the first switch 4 is located below the slide 5, and the trigger 3 is composed of two L-shaped arms. The input end of the trigger 3 is located on the arm close to the slide 5, and the output end of the trigger 3 is located on the arm close to the first switch 4.
[0027] In the implementation of this scheme, a transverse linear slide 5 is preferably used. The slider 6 slides in the linear slide 5. One arm of the trigger 3 is exposed on the sliding path of the slide 5, and the other arm is used to abut against the first switch 4. The arm exposed on the sliding path of the slide 5 is the input end 7, and the arm used to abut against the first switch 4 is the output end 8.
[0028] This solution also provides an electric cabinet, including a cabinet body, wherein a position signal triggering device 1 is provided inside the cabinet body. The position signal triggering device 1 adopts the position signal triggering device 1 described in any of the above-mentioned improved solutions, and the platform 2 is connected to the cabinet body.
[0029] When implementing this solution, the micro-signal triggering device is installed on the cabinet and can be fixed by bolts or welding. Then, the wiring is manually connected to enable it to control the electric cabinet through signal triggering.
[0030] This solution also provides an electric drawer, including a drawer body 10, wherein an arrival signal triggering device 1 is provided inside the drawer body 10, and the arrival signal triggering device 1 adopts the arrival signal triggering device 1 described in any of the above-mentioned improved solutions, and the platform 2 is connected to the drawer body 10.
[0031] In implementing this solution, the micro-signal triggering device is installed on the drawer body 10 and can be fixed by bolt connection or welding. Then, the wiring is manually connected to enable the electric drawer to be controlled by signal triggering.
