Description

Technical Field

[0001] This utility model relates to a lifting basket, and more particularly to an anti-pinch lifting basket. Background Technology

[0002] Because of their height, upper kitchen cabinets often require a chair to use, causing inconvenience. Therefore, height-adjustable pull-out baskets have been introduced to the market. When needed, the basket moves downwards; after use, it moves upwards back into the cabinet. Chinese utility model patent CN221179862U discloses a double-layer anti-pinch pull-out basket, including a cabinet body composed of a base plate with a hollow structure, a clamping plate, and side plates. A touch switch assembly is installed within the hollow structure. A pull-out basket connecting plate is fixedly connected to the rear end of the side plates, and a vertical drive assembly is slidably connected to the pull-out basket connecting plate. The drive component of the vertical drive assembly is a motor, and the motor's start and stop are controlled by an external controller. When the touch switch assembly is off, the motor runs; when the touch switch assembly is on, the motor stops. During use, the lower sheet metal part contacts the first base plate, and the upper sheet metal part is connected to the bottom of the iron plate base. When the lower sheet metal part is subjected to other external forces, the lower electrode moves downward and contacts the upper electrode, which triggers the limit switch. After the trigger switch assembly runs, it transmits a signal to the external controller. The external controller transmits a signal to the motor, and the motor stops driving, thereby stopping the cabinet from running. This achieves the function of preventing hand pinching and protecting objects below. This utility model realizes the anti-pinch function of the bottom plate. However, when the pull-out basket cabinet is rising and the cabinet door is closed, if you reach for an item on the bottom plate, your hand will be between the front baffle of the bottom plate and the cabinet door. As the cabinet continues to rise, if you do not release your hand in time, your arm will be pinched by the front baffle and the cabinet door. If the machine does not stop, your arm may be injured. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an anti-pinch lifting basket.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-pinch lifting basket, comprising a lifting mechanism, a cabinet, and a controller. The controller controls the lifting mechanism to drive the cabinet to move up and down. The lower end of the cabinet is provided with a base plate, and the front end of the base plate is provided with a front baffle. The upper end of the front baffle is provided with a movable rod. An elastic support and a micro switch are provided between the movable rod and the front baffle. The micro switch is electrically connected to the controller. During the upward movement of the cabinet, when the movable rod is pressed downward and triggers the micro switch, the controller controls the lifting mechanism to drive the cabinet to move downward a certain distance and then stop moving.

[0005] The upper end of the front baffle is provided with a slot, the micro switch is located at the bottom of the slot, and the movable rod includes a lower rod body inserted into the slot and an upper rod body located on the upper part of the lower rod body. The width of the upper rod body is greater than the width of the slot opening.

[0006] The elastic support includes a screw threadedly connected to the slotted bottom surface and a spring sleeved on the screw.

[0007] The base plate has side plates on the left and right sides. The inner side of the side plate has an opening corresponding to the movable rod. The two ends of the movable rod are inserted into the openings of the left and right side plates respectively to restrict the upward movement of the movable rod.

[0008] The beneficial effects of this utility model are as follows: A movable rod is provided at the upper end of the front baffle. An elastic support and a micro switch are provided between the movable rod and the front baffle. During the process of the cabinet rising, when the movable rod is pressed down and triggers the micro switch, the controller controls the lifting mechanism to drive the cabinet to move down a certain distance and then stop moving. This avoids the hands being pinched by the cabinet door and the front baffle and improves the safety of the product. Attached Figure Description

[0014] like Figures 1-5As shown, an anti-pinch lifting basket includes a lifting mechanism 10, a cabinet 20, and a controller 30. The controller 30 controls the lifting mechanism 10 to drive the cabinet 20 to move up and down. The lower end of the cabinet 20 is provided with a base plate 21, and the front end of the base plate 21 is provided with a front baffle 22. The upper end of the front baffle 22 is provided with a movable rod 23. An elastic support 24 and a micro switch 25 are provided between the movable rod 23 and the front baffle 22. The micro switch 25 is electrically connected to the controller 30. During the upward movement of the cabinet 20, when the movable rod 23 is pressed downward and triggers the micro switch 25, the controller 30 controls the lifting mechanism 10 to drive the cabinet 20 downward a certain distance and then stop. The lifting mechanism 10 and the controller 30 can both adopt existing technologies, such as Chinese Utility Model Patent No. CN221179862U.

[0015] The upper end of the front baffle 22 is provided with a slot 221, and the micro switch 25 is disposed at the bottom of the slot 221. The movable rod 23 includes a lower rod body 231 inserted into the slot 221 and an upper rod body 232 disposed on the upper part of the lower rod body 231. The width of the upper rod body 232 is greater than the width of the slot opening of the slot 221. In this embodiment, two micro switches 25 are provided in the slot 221, respectively near the left and right ends of the front baffle 22.

[0016] The elastic support member 24 includes a screw 241 threadedly connected to the bottom surface of the slot 221 and a spring 242 sleeved on the screw 241. In this embodiment, three elastic support members 24 are provided in the slot 221 at equal intervals.

[0017] The base plate 21 has side plates 26 on its left and right sides. The inner side of the side plate 26 has an opening 261 corresponding to the movable rod 23. The two ends of the movable rod 23 are respectively inserted into the openings 261 of the left and right side plates 26 to restrict the upward movement of the movable rod 23.
