[0024] The utility model makes further specific description in connection with the drawings. A kind of trigger switch of lift cabinet, it includes the switch seat 2 of installation in the bottom of lift cabinet 1 side plate 11 and the suspension seat 3 of fixed connection above bottom plate 10, the bottom of the switch seat 2 is open to form installation cavity 21, drive seat 4 is hinged in installation cavity 21 two sides by connecting shaft 45;The lug slot 41 of drive seat 4 one side is formed, and the hanging plate 31 of protruding suspension seat 3 two sides is inserted into the lug slot 41, and is hinged with drive seat 4 by drive rod 5, and bottom plate 10 is suspended and installed in the bottom of side plate 11;

[0025] The trigger switch further includes switch plate 6, and the bottom of switch plate 6 is equipped with micro switch 61, and micro switch 61 is set to downward and towards switch plate 6 direction, correspondingly, the end surface of drive seat 4 is provided with contact 43, and bottom plate 10 is pressed, drive seat 4 rotates along drive rod 5, and contact 43 triggers micro switch 61 to generate electric control signal, controls the lifting movement of lift cabinet 1.

[0026] The lug slot 41 is provided with hinged hole 44, and drive rod 5 is inserted into the hinged hole 44, and hanging plate 31 swings in lug slot 41 along drive rod 5;The outside of lug slot 41 is open to form avoidance slot 42, and the avoidance slot 42 and lug slot 41 are connected with arc transition.

[0027] The top plate of hanging plate 31 is provided with semicircle.

[0028] The front and rear sides of drive seat 4 are provided with connecting shaft 45, and the switch seat 2 is provided with connecting hole 22, and connecting shaft 45 is inserted and clamped in the connecting hole 22, and drive seat 4 swings in installation cavity 21 along connecting shaft 45.

[0029] The installation cavity 21 is formed with a plurality of positioning columns 24, and the end surface of switch plate 6 is provided with positioning hole 62, and the positioning column 24 is inserted into and clamped in the positioning hole 62, and the switch plate 6 is clamped between drive seat 4 and installation cavity 21.

[0030] The switch seat 2 is provided with adjusting hole 23, and the adjusting hole 23 is communicated with installation cavity 21;The adjusting hole 23 and hinged hole 44 are eccentrically arranged.

[0031] The drive rod 5 is cross countersunk bolt.

[0032] Working principle: The switch seat is installed at the bottom of the side plate of the lifting cabinet, and the installation cavity is formed at the bottom of the switch seat. The driving seat is hinged on both sides of the installation cavity by the connecting shaft. The suspension seat is installed on the bottom plate of the lifting cabinet, and the hanging plate is protruded on the suspension seat. The hanging plate is inserted into the slot of the driving seat and is hinged and installed with the driving seat, so that the bottom plate is suspended and installed at the bottom of the side plate.

[0033] When the user lightly presses the bottom plate driving seat upwards, the driving seat rotates along the driving rod, and the contact arranged at the end face of the driving seat is connected with the micro switch installed at the bottom of the switch plate. The micro switch is powered on to start, and an electric control signal is fed back to the control system to control the lifting movement of the lifting cabinet.

[0034] The precise contact between the contact and the micro switch ensures that the operation of the lifting cabinet is quick and accurate, and has high sensitivity. The use of the micro switch for control effectively avoids the problems of accidental touch or delayed triggering start of the traditional switch. The user can control the lifting movement of the lifting cabinet more agilely. During the lifting control of the lifting cabinet, the user only needs to apply slight force to achieve the operation, which is not limited to manual operation. The user can easily operate when holding objects with both hands.

[0035] The lifting cabinet also has an anti-collision mechanism to ensure that the lifting cabinet can adjust the descending speed or stop the descending movement in time when it touches obstacles during lifting, avoiding further collision with the objects and protecting the objects and the cabinet. Specifically, the driving rod is inserted into the hinge hole of the slot, and the hanging plate can swing back and forth in the slot along the driving rod. When the lifting cabinet is lowered to a certain height, if the bottom plate collides with the objects in the cabinet, the bottom plate will be subjected to an upward reaction force, and the driving seat will rotate in the opposite direction along the driving rod. The lifting cabinet stops descending in time to avoid excessive pressing or damage to the micro switch, effectively buffers the impact force and prevents damage to the objects in the cabinet due to collision. At the same time, if the bottom plate contacts the dishes or the user's body parts or fragile objects such as eggs during the descending process of the lifting cabinet, the trigger switch can quickly respond in time to transmit the electric control signal to the control system, and the lifting cabinet stops descending, effectively avoiding damage to the objects and improving safety.

[0036] The connecting shafts are protruded on the front and back sides of the driving base, the connecting holes are arranged on the switch base, the connecting shafts are inserted and clamped in the connecting holes, the driving base swings in the installation cavity along the connecting shafts, thereby connecting and installing the driving base and the switch base.

[0037] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
