Description

Technical Field

[0001] This utility model relates to the field of trash can technology, specifically a foot-operated anti-pinch trash can. Background Technology

[0002] A pedal-operated trash can uses the lever principle; the lid is opened by stepping on the foot pedal at the bottom of the trash can, making it simple, convenient, and quick to operate.

[0003] For example, a foot-operated waste sorting and protective recoil structure (Announcement No.: CN222409570U) includes a container, an inlet, and protective auxiliary components. A foot pedal is located at the bottom of one side of the container, and a connecting plate is located at the bottom inner side of the container. A force-transmitting connecting rod is located at the upper end of the connecting plate, and the force-transmitting connecting rod is connected to the connecting plate via a hydraulic rod. The protective auxiliary components are located inside the container and include a sliding component and an auxiliary component. By setting the protective auxiliary components at the connecting end of the foot-operated waste sorting container, the foot pedal of the foot-operated waste bin can be protected against recoil. During use, the sliding component and auxiliary component ensure that the cover will not pinch the user's hand, thus meeting practical usage requirements.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the aforementioned equipment integrates multiple components such as a motor, threaded rod, threaded sleeve, sliding rod, first slider, fixing plate, connecting block, and rubber protrusions, making the overall structure quite complex. This not only increases manufacturing costs but also increases maintenance difficulty and failure rate. If a component fails, multiple components may need to be disassembled for repair. At the same time, although the threaded drive is stable and reliable, its transmission efficiency is relatively low, which means that when the cover is opened and closed, attention must be paid to whether the motor in the sliding component is running. Therefore, we need to propose a foot-operated anti-pinch trash can. Utility Model Content

[0005] The purpose of this utility model is to provide a foot-operated anti-pinch trash can. By using the cooperation of the large cover plate and the small cover plate in the anti-pinch cover assembly, the anti-pinch cover assembly can, to a certain extent, prevent the hand from being pinched when closing the inlet, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A foot-operated anti-pinch trash can includes a can body, an inlet is provided on one side of the top of the can body, an anti-pinch cover assembly is provided on one side of the inlet, a foot pedal is provided on the bottom side of one side of the can body, and a force transmission linkage device connecting the foot pedal and the anti-pinch cover assembly is provided inside the can body.

[0008] The anti-pinch cover plate assembly includes a large cover plate, which is installed at the end of the movable end of the force transmission linkage device, and a small cover plate is movably installed at the bottom of the large cover plate.

[0009] Preferably, a sealing frame is fixedly installed on one side of the box body at the inlet, and a sealing gasket is fixedly adhered to one side of the sealing frame. Both the large cover plate and the small cover plate are movably fitted to one side of the sealing gasket.

[0010] Preferably, two sets of hinges are symmetrically fixedly installed on one side of the bottom of the large cover plate, and one side of the movable end of each set of hinges is fixedly installed to one side of the small cover plate.

[0011] Preferably, a base plate is fixedly installed at the bottom of the container, and an inner box for storing garbage is movably installed on the top of the base plate. Clamping components are provided on both sides of the inner box.

[0012] Preferably, the clamping assembly includes a clamping plate, one side of which is fitted against one side of the inner box, and two sets of springs are symmetrically fixedly installed on the other side of the clamping plate, with one end of each set of springs fixedly installed to one side of the inner wall of the box.

[0013] Preferably, a telescopic rod is fixedly installed inside the box body of the spring, and one end of the telescopic rod is fixedly connected to one side of the clamping plate.

[0014] Preferably, a material retrieval port is provided on one side of the box to facilitate the retrieval of the inner box, and a box door is hinged inside the material retrieval port.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, through the setting of the anti-pinch cover plate assembly and the sealing frame, allows the large cover plate and the small cover plate in the anti-pinch cover plate assembly to cooperate. When the anti-pinch cover plate assembly closes the inlet, if a person's hand is still resting on the bottom of the sealing frame, the large cover plate first closes and fits the sealing frame. The small cover plate, which is movably installed at the bottom of the large cover plate, can rotate away from the inlet with the cooperation of the two combined flaps. This can prevent the hand from being pinched to a certain extent. After the hand is removed, the small cover plate can fit and close the bottom of one side of the sealing frame, and cooperate with the large cover plate to close the sealing frame and the inlet.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A foot-operated anti-pinch trash can includes a can body 1. An inlet 2 is provided on one side of the top of the can body 1. An anti-pinch cover assembly 3 is provided on one side of the inlet 2. A foot pedal 4 is provided on the bottom side of one side of the can body 1. A force-transmitting linkage device 5 is provided inside the can body 1, connecting the foot pedal 4 and the anti-pinch cover assembly 3. (The force-transmitting linkage device 5 refers to the prior art in the background art, a foot-operated garbage sorting protection recoil structure (announcement number: CN222409570U). The principle and usage of the force-transmitting linkage device 5 are the same as the prior art, and will not be described again here.)

[0025] The anti-pinch cover plate assembly 3 includes a large cover plate 31, which is installed at the end of the movable end of the force transmission linkage device 5, and a small cover plate 32 is movably installed at the bottom of the large cover plate 31.

[0026] The large cover plate 31 and the small cover plate 32 form a double-layer movable cover plate. The large cover plate 31 is controlled to open and close as a whole by the telescopic end of the force transmission linkage device 5. The small cover plate 32 is hinged to the large cover plate 31 by the bottom hinge 33. When the double cover plates are closed, they fit tightly against the sealing gasket 7 to prevent odor leakage.

[0027] Furthermore, a sealing frame 6 is fixedly installed on one side of the box body 1 at the inlet 2, and a sealing gasket 7 is fixedly bonded to one side of the sealing frame 6. The large cover plate 31 and the small cover plate 32 are both movably attached to one side of the sealing gasket 7.

[0028] The sealing frame 6 is fixed to the edge of the inlet 2. The sealing gasket 7 is made of elastic rubber and is bonded to the inside of the frame. It fits tightly with the closing surfaces of the large and small covers. The elastic sealing gasket compensates for the machining tolerances of the covers and adapts to long-term wear. The rubber material is resistant to garbage corrosion and extends service life. When the covers are closed, the sealing gasket buffers the impact noise.

[0029] Furthermore, two hinges 33 are symmetrically fixedly installed on one side of the bottom of the large cover plate 31, and one side of the movable end of each hinge 33 is fixedly installed on one side of the small cover plate 32.

[0030] A hinge-type linkage structure is formed, and the double hinges 33 support the small cover plate 32 to stabilize its opening and closing trajectory, avoiding deformation due to single-point stress. The hinges 33 can be disassembled and replaced individually, reducing maintenance costs.

[0031] Furthermore, a base plate 10 is fixedly installed at the bottom of the container 1, and an inner box 8 for storing garbage is movably installed on the top of the base plate 10. Clamping components 9 are provided on both sides of the inner box 8.

[0032] The inner box 8 is placed on the base plate 10, and the two sides are self-adaptively clamped by the clamping components 9. The box door 11 is hinged to the material outlet, making it easy to remove the inner box 8 for cleaning or disinfection.

[0033] Specifically, the clamping assembly 9 includes a clamping plate 91, one side of which is attached to one side of the inner box 8, and two sets of springs 92 are symmetrically fixedly installed on the other side of the clamping plate 91. One end of each set of springs 92 is fixedly installed to one side of the inner wall of the box 1.

[0034] Spring 92 provides flexible fixation, and the inner box 8 can be pulled out and replaced with one hand. Spring 92 provides radial clamping force, and telescopic rod 93 restricts the lateral deformation of spring 92 to ensure the stability of inner box 8.

[0035] It is worth noting that one end of each of the two sets of clamps 91 is arc-shaped, and the arc-shaped ends of the two sets of clamps 91 form a trumpet-shaped structure that facilitates the removal and placement of the inner box 8.

[0036] Furthermore, a telescopic rod 93 is fixedly installed inside the spring 92 in the housing 1, and one end of the telescopic rod 93 is fixedly connected to one side of the clamping plate 91.

[0037] The telescopic rod 93 limits the direction of movement of the clamping plate 91, and the pressure of the spring 92 can adapt to different inner box sizes 8 or fluctuations in garbage weight. The telescopic rod 93 prevents excessive compression of the spring, which could lead to plastic deformation. The purely mechanical structure is suitable for humid environments.

[0038] Furthermore, a material retrieval port is provided on one side of the box body 1 to facilitate the loading and unloading of the inner box 8, and a box door 11 is hinged inside the material retrieval port.

[0039] The door 11 is connected to the material inlet via a hinge, with an opening angle greater than 90°. The top of the inner box 8 is lower than the lower edge of the material inlet. The large opening design prevents the inner box 8 from getting stuck, improving cleaning efficiency. When the door 11 is closed, it is flush with the surface of the box body 1, with no protruding structure.

[0040] Working principle: When this utility model is in use, the large cover plate 31 and the small cover plate 32 of the anti-pinch cover plate assembly 3 close under the reset action of their own weight and the force transmission linkage device 5, and are tightly attached to the sealing gasket 7 on one side of the sealing frame 6 to form a closed and sealed state. The springs 92 in the two sets of clamping assemblies 9 are in a natural state, and the inner box 8 is firmly clamped to the bottom plate 10 through the two sets of clamping plates 91.

[0041] When the user presses the foot pedal 4, the force is transmitted to the large cover plate 31 via the force transmission linkage device 5 (using the lever principle of CN222409570U). The large cover plate 31 flips upward around its hinge point and opens, simultaneously causing the small cover plate 32 at the bottom hinge to open as well. The inlet 2 is fully opened. After the user throws away the trash through the opening and releases the foot pedal 4, the force transmission linkage device 5 pulls back under the action of gravity, causing the large cover plate 31 to drive the small cover plate 32 to close synchronously. When the anti-pinch cover assembly 3 is closing the inlet 2, if a person... With the hand still resting on the bottom of the sealing frame 6, the large cover plate 31 first seals and fits the sealing frame 6. The small cover plate 32, which is movably installed at the bottom of the large cover plate 31, can rotate away from the inlet 2 with the cooperation of the two combined pages 33. The small cover plate 32 will rest on the back of the hand, thus avoiding the hand being pinched to a certain extent. After the hand is removed, the small cover plate 32 can fit and seal the bottom of one side of the sealing frame 6. Together with the large cover plate 31, the sealing frame 6 and the inlet 2 are sealed through the sealing gasket 7 to prevent odor leakage.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
