Description

Technical Field

[0001] This utility model relates to the field of trigger switch technology, specifically a manual / automatic trigger device. Background Technology

[0002] Traditional electric drawers generally have two modes: manual operation and automatic control. The switching between these two modes is usually controlled by a switch. When automatic control is active, the trigger device closes the switch, and the automatic sensing component is in working condition. At this time, the automatic sensing component in the electric drawer can sense the signal and transmit it to the drive mechanism to drive the drawer to open or close. At this time, the manual operation station is blocked by the baffle, and those skilled in the art cannot operate it manually by inserting a key. Conversely, when the trigger device is open, the automatic control is disabled, and the electric drawer enters manual mode. A utility model patent discloses a manual drive device for an electrically operated circuit breaker drawer (publication number: CN222763473U), including a housing, a manual drive mechanism, and a clutch mechanism linked to the manual drive mechanism. The manual drive mechanism includes a motor and a first gear connected to the motor, and the clutch mechanism includes a clutch and a second gear connected to the clutch. The drive mechanism and the clutch mechanism are connected by meshing of the first gear and the second gear. By improving the structure of the manual drive mechanism and the clutch mechanism, the two components are integrated into one component, and the first gear and the second gear are protected by the housing. This reduces the complexity of installing the manual function of the circuit breaker drawer, so that personnel do not need to distinguish the installation position and different components when installing the clutch mechanism and the manual drive mechanism. The manual drive disclosed in the above-mentioned utility model requires manual sliding of the operating lever to trigger the switch by touching it. At this time, the automatic control fails, and the manual operation station is exposed. Those skilled in the art can manually operate it with a key to avoid conflict between manual and automatic operation. However, the contact between the operating lever and the switch is easily malfunctioned due to the movement of the operating lever. Especially in this structure that uses a single switch, the operating lever cannot maintain contact with the switch to continuously trigger it. If the drawer is affected by the failure of the operating lever during manual operation and the automatic control is activated, it is easy to damage the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a manual / automatic operation triggering device that can improve the problem of poor stability in manual / automatic operation switching of traditional triggering devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a manual / automatic triggering device, comprising a device body, a manual operating mechanism, and an automatic trigger. The manual operating mechanism includes a movable contact component and an operating end. The device body includes a limiting window and a slider. The slider is placed in the limiting window. The movable contact component and the operating end are connected by the slider. When the operating end slides, it causes the movable contact component to contact the automatic trigger, and the automatic trigger is activated. When the operating end slides, it causes the movable contact component to separate from the automatic trigger, and the automatic trigger is deactivated. The limiting window limits the slider, allowing the movable contact component to continuously trigger the automatic trigger.

[0005] As a further improvement of this utility model, the manual operating mechanism includes a manual wheel. When the operating end slides and drives the moving contact component to contact the automatic trigger, the operating end blocks the manual wheel. When the operating end slides and drives the moving contact component to separate from the automatic trigger, the manual wheel is exposed.

[0006] As a further improvement of this utility model, the automatic trigger includes a trigger spring, the position of which is opposite to the moving contact component, and when the automatic trigger is activated, the moving contact component abuts against the trigger spring.

[0007] As a further improvement of this utility model, the limiting window limits the slider in the vertical direction, the slider can slide left and right along the length direction of the limiting window, the trigger spring is located on the upper or lower end surface of the automatic trigger, and the moving contact component can continuously press on the trigger spring to make the automatic trigger effective.

[0008] As a further improvement of this utility model, the manual wheel and the automatic trigger are arranged in the same straight line.

[0009] As a further improvement of this utility model, the device body is provided with a limit lock, and the limit lock is set at the position of the movement path of the operating end.

[0010] Compared with existing technologies, this utility model provides a manual-automatic triggering device with the following advantages: A stable guide and limiting cooperation is formed between the limiting window and the slider; the operating end is connected to the moving contact component; a single-handed sliding of the operating end can drive the moving contact component to contact or separate from the automatic trigger. Furthermore, during contact or separation, the limiting window prevents the moving contact component from deviating from its position, achieving rapid activation and reliable deactivation of the automatic triggering function. The transmission path is short, the structure is compact, and the switching is sensitive; the limiting window ensures that each action is completed correctly, avoiding mis-connections and false triggers, significantly improving safety and ease of operation.

[0013] As shown in the figure, to achieve the above-mentioned objective, this utility model provides a manual-automatic triggering device, including a device body 1, a manual operation mechanism 2, and an automatic trigger 3. The manual operation mechanism 2 includes a movable contact component 4 and an operation end 5. The device body 1 includes a limiting window 6 and a slider 7. The slider 7 is placed in the limiting window 6. The movable contact component 4 and the operation end 5 are connected through the slider 7. When the operation end 5 slides, it causes the movable contact component 4 to contact the automatic trigger 3, and the automatic trigger 3 is activated. When the operation end 5 slides, it causes the movable contact component 4 to separate from the automatic trigger 3, and the automatic trigger 3 is deactivated. The limiting window 6 limits the slider 7, allowing the movable contact component 4 to continuously trigger the automatic trigger 3.

[0014] In this implementation, the device body 1 serves as a supporting foundation, with a limiting window 6 on it. The limiting window 6 can be oblong. The slider 7 is slidably accommodated within the limiting window 6. The inner circumferential wall of the limiting window 6 can constrain the slider 7 to move only in a specific direction, ensuring the certainty of the sliding trajectory. The manual operation mechanism 2 includes a moving contact component 4 and an operating end 5. Both the moving contact component 4 and the operating end 5 are connected to the slider 7, and the three constitute a synchronously moving assembly. The connection method can be: the moving contact component 4 is a contact rod or contact block extending from one side of the slider 7, and the operating end 5 is a handle, lever, or push-pull component fixed to the other side of the slider 7. The moving contact component 4, the operating end 5, and the slider 7 can be connected by bolts, snap-fit, or integral molding. The automatic trigger 3 is installed on the device body 1, and its installation method can be the same as in the prior art. It has a trigger interface and changes its effective state when it is acted upon by the moving contact component 4. In this scheme, the specific direction in which the limiting window 6 constrains the slider 7 refers to the direction in which the moving contact component 4 and the automatic trigger 3 work together. For example, if the moving contact component 4 works with the upper end face 10 of the automatic trigger 3, then the limiting window 6 will constrain the vertical movement direction of the slider 7 within the limiting window 6, preventing the moving contact component 4 from leaving the work station without constraint after contacting the automatic trigger 3. At this time, the moving contact component 4 can be continuously triggered by the limiting window 6.

[0015] In one embodiment of this solution, the operating end 5 is a push button, which is exposed on the device body 1 for finger operation. The movable contact component 4 is a pressure block connected to the slider 7. The automatic trigger 3 adopts a contact switch, with its contact located on the movement path of the movable contact component 4. When a person skilled in the art pushes the push button, the slider 7 slides, causing the pressure block of the movable contact component 4 to press against the switch contact, thus activating the automatic trigger 3; pulling the push button backward disengages the pressure block from the contact, resets the switch, and disables the automatic trigger 3. The clearance fit between the limiting window 6 and the slider 7 ensures smooth sliding without significant wobble.

[0016] In other embodiments, those skilled in the art can modify the circuit layout so that the pressing block of the moving contact component 4 presses against the switch contact, causing the automatic trigger 3 to fail; when the block disengages from the contact, the switch resets, and the automatic trigger 3 becomes active. The activation and deactivation of the automatic trigger 3 are controlled by sliding the operating terminal 5, resulting in a simple structure and intuitive operation.

[0017] As an improved specific implementation, the manual operating mechanism 2 includes a manual wheel 8. When the operating end 5 slides and drives the moving contact component 4 to contact the automatic trigger 3, the operating end 5 blocks the manual wheel 8. When the operating end 5 slides and drives the moving contact component 4 to separate from the automatic trigger 3, the manual wheel 8 is exposed.

[0018] In this implementation, the manual wheel 8 is mounted on the device body 1 and connects with other manual operating components on the device body 1 for manual control in the event of a failure of the automatic trigger 3. The relative position and shape between the operating end 5 and the manual wheel 8 can be configured to have an obstructing relationship: when the operating end 5 slides to the active position where the moving contact component 4 contacts the automatic trigger 3, the operating end 5 itself or its extension reaches the front of the manual wheel 8, obstructing the operating area of ​​the manual wheel 8, preventing the operator from operating the manual wheel 8 to initiate manual operation; when the operating end 5 slides to the failure position where the moving contact component 4 separates from the automatic trigger 3, the operating end 5 moves away from the front of the manual wheel 8, the manual wheel 8 is fully exposed, and the operable state is restored.

[0019] In this design, the operating end 5 can be a long, narrow slide plate. The position of the corresponding moving contact part 4 on the slide plate is connected to the moving contact part 4. The slide plate slides via the slider 7, and the other end is provided with a baffle to block the operating area of ​​the manual wheel 8. When the slide plate is pushed forward to the active position of the automatic trigger 3, the slide plate moves forward as a whole, and the baffle covers the operating opening of the wheel. When the slide plate is pulled backward to the inactive position, the baffle retracts, and the operating opening of the manual wheel 8 is exposed.

[0020] As an improved specific implementation, the automatic trigger 3 includes a trigger spring 9, the position of which is opposite to the moving contact component 4. When the automatic trigger 3 is activated, the moving contact component 4 abuts against the trigger spring 9.

[0021] In this implementation, the trigger spring 9 can be made of a thin, elastic metal sheet. One end is fixed to the insulating base or housing of the automatic trigger 3 to form a fulcrum, while the other end is a free, movable end. When the spring 9 presses down to trigger the signal, the circuit is connected; conversely, when it releases, the circuit is disconnected. The moving contact component 4 is positioned relative to the trigger spring 9. In this design, the free end includes an arc segment 14, and its movement path corresponds to the position of the arc segment 14 on the trigger spring 9. Using the arc segment 14 allows for a longer compression stroke, enabling a more complete trigger signal. When the automatic trigger 3 is activated, the moving contact component 4 abuts against the trigger spring 9.

[0022] In one embodiment, the fixed end of the trigger spring 9 is installed inside the housing of the automatic trigger 3, and the free end is curved upward and serves as the force-bearing point opposite to the moving contact component 4. When the operating end 5 pushes the slider 7 to the active position, the moving contact component 4 presses down on the free end of the trigger spring 9, causing the trigger spring 9 to be pressed down after being subjected to force, pressing down the normally open contact of the trigger switch to the closed contact, connecting the trigger circuit, and the automatic trigger 3 becomes active; when the operating end 5 slides in the opposite direction, the moving contact component 4 disengages from the trigger spring 9, and the trigger spring 9 returns to its original position by the spring of the switch, separating from the fixed contact, and the automatic trigger 3 becomes inactive.

[0023] As an improved specific implementation, the limiting window 6 limits the slider 7 in the vertical direction, the slider 7 can slide left and right along the length direction of the limiting window 6, the trigger spring 9 is located on the upper end surface 10 or the lower end surface 11 of the automatic trigger 3, and the moving contact component 4 can continuously press on the trigger spring 9 to make the automatic trigger 3 take effect.

[0024] In this implementation, the limiting window 6 not only restricts the sliding direction of the slider 7, but also applies vertical limiting to the slider 7. That is, the upper and lower inner walls of the limiting window 6 cooperate with the top and bottom surfaces of the slider 7, respectively, so that the slider 7 has no freedom of movement in the height direction and can only slide left and right along the length direction of the limiting window 6. The trigger spring 9 is set corresponding to the upper end surface 10 or the lower end surface 11 of the automatic trigger 3. The trigger spring 9 extends upward from the upper end surface 10 of the automatic trigger 3 or downward from the lower end surface 11. The deformation direction of its free end is respectively towards or away from the moving contact component 4. In other embodiments, when the trigger spring 9 corresponds to the left or right end surface of the automatic trigger 3, the limiting direction of the slider 7 by the limiting window 6 is the left and right direction. The limiting of the slider 7 by the limiting window 6 can prevent the slider 7 from being affected by the elastic force of the trigger spring 9 during sliding, thus preventing it from continuously pressing the trigger spring 9 and triggering or closing the automatic trigger 3.

[0025] As an improved specific implementation, the manual wheel 8 and the automatic trigger 3 are arranged in the same straight line.

[0026] In implementation, the direction of this straight line usually coincides with the sliding direction of the operating end 5. This layout allows the operating end 5 to directly reach the position that obstructs the manual wheel 8 along this straight line while automatically triggering the sliding motion. The structure is compact and the action transmission is direct.

[0027] As an improved specific implementation, the device body is provided with a limit lock 12, and the limit lock 12 is set to the position of the movement path of the operating end.

[0028] In implementation, this solution uses a lock body and a lock base. The lock body can pass through the lock base and be placed on the movement path of the operating end. When the operator needs to limit the operation end, the lock body can be passed through the lock and closed, so that the lock body is partially placed on the movement path of the operating end. At this time, the lock body can limit the movement of the operating end, thereby limiting the operation end by the limit lock 12. This solution can use locks such as bolt locks and padlocks whose lock bodies can pass through the lock base.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
