Description
Technical Field
[0001] The utility model relates to the technical field of laundry chutes, in particular to a bottom buffer device for a laundry chute. Background Technique
[0002] A laundry chute is a transportation passage used in places such as hotels. Due to the high room density in hotels and the special nature of hotels, a large number of clothes need to be washed. Therefore, in order to transport the washed clothes, hotels generally install laundry chutes for transporting clothes. Since a large number of clothes need to be transported through the laundry chute, a buffer mechanism is generally provided at the bottom of the laundry chute.
[0003] A door is provided at the bottom of the laundry chute. After the door is opened, the user can take out the clothes inside the laundry chute. After taking out the clothes, the user also needs to carefully check the inside of the laundry chute. However, since there is no corresponding mechanism above the laundry chute to block suddenly falling clothes and items, the user is easily injured by the falling items when cleaning the laundry chute.
[0004] In view of the above situation, we propose a bottom buffer device for a laundry chute. Content of the Utility Model

[0024] Referring to FIGS. 1-4, a bottom buffer device for a laundry chute includes a main body 1 of the laundry chute. The inner wall below the main body 1 of the laundry chute is rotatably connected to a laundry chute door 2. A handle 3 is fixedly connected to the outer surface of the laundry chute door 2 at a position above the keyhole 6. An indicator light 4 fixedly connected to the outer surface of the main body 1 of the laundry chute is arranged above the laundry chute door 2. A controller 5 fixedly connected to the outer surface of the main body 1 of the laundry chute is arranged on one side of the indicator light 4. A password lock is fixedly connected to the inner wall of the laundry chute door 2. The output end of the password lock is movably clamped to the inner wall of the main body 1 of the laundry chute. The locking mechanism inside the password lock is fixedly connected to a keyhole 6. The keyhole 6 penetrates the laundry chute door 2 and is rotatably connected to the laundry chute door 2. A buffer frame 7 is rotatably connected to the inner wall of the laundry chute door 2. A rotating rod 11 is rotatably connected to the inner wall of the buffer frame 7. Rotating shafts 10 are fixedly connected to both sides of the rotating rod 11 perpendicular to the laundry chute door 2. The rotating shafts 10 penetrate the main body 1 of the laundry chute and are rotatably connected to the inner wall of the main body 1 of the laundry chute. A chute 12 in the shape of a semi-circular arc is opened at the midline position of the bottom of the buffer frame 7. A buffer ball 14 is slidably connected to the inside of the chute 12. The user can open the password lock that locks the laundry chute door 2 through the keyhole 6 and the controller 5. After the user inputs the correct password, the controller 5 can open the password lock and then open the laundry chute door 2.
[0025] On the inner wall of the main body 1 of the laundry chute near the side of the rotating shaft 10, a first movable cavity 8 with an opening facing the direction of the buffer frame 7 is provided. On the lower inner wall of the first movable cavity 8, a hydraulic cylinder 9 is fixedly connected. The output end of the hydraulic cylinder 9 is fixedly connected with a moving block 13 having the same width as the first movable cavity 8. The cross-section of the moving block 13 is "U"-shaped, and the opening of the "U" shape of the moving block 13 is in the same direction as the opening of the first movable cavity 8. On both sides of the inner wall of the moving block 13, second movable cavities 15 are provided. On the lower inner wall of the second movable cavity 15, a spring 18 is fixedly connected. The top of the spring 18 is fixedly connected with a slider 16. The slider 16 is slidably connected inside the second movable cavity 15. The inner wall of the slider 16 is rotatably connected with a buffer ball 14. Inside the spring 18, a damper 17 is provided. The top of the damper 17 is fixedly connected with the bottom of the slider 16, and the bottom of the damper 17 is fixedly connected to the inner wall of the second movable cavity 15. By starting the hydraulic cylinder 9, the user can make the buffer frame 7 rotate, thereby controlling the size of the transportation outlet of the laundry chute, so that when the user cleans the laundry chute, the upper outlet can be blocked, thus preventing the user from being injured by falling objects when cleaning the laundry chute.
[0026] In summary: During the application of the present utility model, when cleaning the laundry chute, the user starts the hydraulic cylinder 9 to move upward, causing the hydraulic cylinder 9 to drive the moving block 13 to move inside the first movable cavity 8, and at the same time driving the buffer ball 14 at the top of the moving block 13 to move upward. The top of the buffer ball 14 slides inside the chute 12, and the buffer ball 14 can support the buffer frame 7. Therefore, when the hydraulic cylinder 9 moves upward, it can drive the buffer frame 7 to rotate counterclockwise, so that the buffer frame 7 can block the upper outlet of the main body 1 of the laundry chute, causing the falling objects to be buffered and blocked, preventing the user from being injured. After the cleaning is completed, the user starts the hydraulic cylinder 9 to drive the buffer frame 7 to rotate clockwise downward, so that the upper outlet of the main body 1 of the laundry chute is exposed, facilitating the user to transport the clothes through the laundry chute. At the same time, the buffer frame 7 rotates to adjust different angles according to the transportation needs. At the same time, the outer surface of the upper part of the buffer frame 7 is provided with a rotating rod 11 with a relatively small friction force, so that the clothes will not hang on the outer surface of the buffer frame 7 during transportation.
[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
