Abstract
Description
Technical Field
[0001] This invention relates to the field of waste collection equipment technology, specifically to a pull-out waste cabinet. Background Technology
[0002] Traditional waste disposal equipment generally suffers from cumbersome operation and high labor consumption in waste collection and replacement. Especially when waste bins are fixed or have top openings, operators often need two people to lift and tilt them to replace them. This not only requires extra manpower but also poses a risk of secondary pollution due to spillage during handling. Existing equipment generally lacks ergonomic pull-out mechanisms, forcing cleaning staff to maintain a bent-over posture for extended periods. Statistics show that this prolonged bending posture reduces work efficiency and significantly increases the incidence of muscle strain.
[0003] Therefore, there is an urgent need for a pull-out waste disposal cabinet that can be operated by a single person. Summary of the Invention
[0004] Purpose of the invention: The purpose of this invention is to address the shortcomings of existing technologies by providing a pull-out waste bin. Through the coordinated operation of a sliding device, a button lock, and a through hinge, a single person can complete operations such as emptying the waste bin and changing garbage bags while in an upright position.
[0005] Technical solution: The present invention provides a pull-out waste cabinet, comprising a cabinet body and a waste bin, the waste bin being completely housed inside the cabinet body. A sliding device is provided at the bottom of the cabinet body, on which the waste bin is placed, and the action of extending out of the cabinet body or being housed inside the cabinet body is completed by extending and retracting the sliding device. The cabinet body includes wall panels, door panels, top panels, and bottom panels. The door panels and the sliding device are connected by through hinges, and the door panels and the top panel are locked or unlocked by a button lock.
[0006] The cabinet serves as the core supporting structure, with all other components directly or indirectly fixed within its frame. The base support is fixed to the bottom of the cabinet, acting as the mounting base for the waste bin seat guide rail, ensuring its stability and load-bearing capacity. The waste bin seat guide rail is fixed to the base support by bolts or welding, precisely engaging with the sliding mechanism at the bottom of the waste bin seat for horizontal pull-out. The waste bin seat, connected to the base support, supports the waste bin and features a slider or roller structure at its bottom that matches the guide rail, ensuring smooth pull-out. The cabinet door is hinged to the side of the cabinet via a through-hing, with the hinge axis coinciding with the door's rotation axis, allowing the door to rotate 90° to the left. A push-button lock is embedded inside the cabinet door; the latch engages with a latch hole on the cabinet via a spring mechanism. Pressing the button triggers the latch to depress, releasing the engagement. The waste bin is placed inside the waste bin seat and secured by clips or gravity, ensuring no displacement during pull-out.
[0007] Furthermore, the sliding device includes a base fixed to the base plate, a waste bin seat fixedly connected to the upper part of the base, a waste bin of appropriate size placed on the waste bin seat, and the bottom of the base fixed to the base plate by a waste bin seat guide rail. The waste bin seat guide rail drives the waste bin seat to slide, thereby driving the waste bin to slide.
[0008] Furthermore, a reinforcing rib is fixed on each side of the waste bin seat. One end of the reinforcing rib is fixed to the waste bin seat guide rail, and the other end of the reinforcing rib is fixed to the door panel, forming a triangular stable structure to prevent the waste bin seat from lateral twisting due to load eccentricity.
[0009] Furthermore, the push-button lock includes a button body fixed to the door panel. The bottom of the button body is connected to the latch via a spring. It also includes a latch hole fixed at a corresponding position on the top panel. Under normal conditions, the latch is held in an extended state by the spring force, engaging with the latch hole to maintain the locked state between the door panel and the top panel. The button is rigidly connected to the latch. Pressing it directly pushes the latch out of the latch hole. During the button press, the spring is compressed and stores energy, providing power for reset. After the latch is completely disengaged from the latch hole, it triggers the linkage mechanism with the through hinge (such as releasing the latch or disengaging the magnetic attraction), allowing the cabinet door to rotate freely. When the user releases the button, the elastic potential energy of the compressed spring is converted into kinetic energy, pushing the button and latch back to their original positions. The latch re-inserts into the latch hole, restoring the locked state. The end of the latch is designed with a bevel or rounded corner, so even if there is slight misalignment, it can automatically align with the latch hole by pressing.
[0010] Furthermore, the diameter of the latch hole is larger than the diameter of the latch.
[0011] Furthermore, the hollow hinge includes a hollow shaft. A first bushing provides an interference fit with a fixed blade, while a second bushing provides a clearance fit with a movable blade. The fixed side of the fixed blade is fixedly mounted on a sliding device, and the fixed side of the movable blade is fixedly mounted on the door panel. The interference fit between the hollow shaft and the first bushing ensures no misalignment of the rotation axis, while the clearance fit between the hollow shaft and the second bushing ensures free rotation. When the button lock is unlocked, a mechanical linkage (such as releasing the latch or disengaging the magnetic attraction) releases the restriction on the hinge's rotational freedom.
[0012] Furthermore, a handle is provided on the outward-facing side of the door panel. By grasping the handle, the waste bin seat can be pulled horizontally to the limit point.
[0013] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows:
[0014] (1) The linkage mechanism between the cabinet door button lock and the sliding device in this invention is that when the cabinet door is unlocked, it opens to the side at 90° to form an operating space. With the help of the guide rail, the waste bin that originally needed to be lifted vertically is transformed into a horizontal sliding mode, reducing the mechanical work of picking up and putting down. This invention allows the operator to complete the operation by one person, saving operation time compared with the traditional two-person lifting mode, while avoiding the risk of asynchronous actions in multi-person collaboration.
[0015] (2) The button lock designed in this invention can be unlocked by pressing with one hand, without the need for auxiliary tools or multiple people working together;
[0016] (3) The through hinge designed in this invention makes the opening and closing trajectory of the cabinet door completely controlled, avoiding the left and right offset problem of traditional hinges. At the same time, the limiting device prevents the cabinet door from being over-opened, causing the center of gravity to become unbalanced, which is especially suitable for heavy-duty waste bins.

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.
[0030] like Figure 1 The pull-out waste cabinet shown includes a cabinet body 1 and a waste bin 2. The waste bin 2 is completely stored inside the cabinet body 1. A sliding device is provided at the bottom of the cabinet body 1. The waste bin 2 is placed on the sliding device 3. As the sliding device 3 extends and retracts, it can extend out of the cabinet body 1 or be stored inside the cabinet body 1. The cabinet body 1 includes a wall panel 101, a door panel 102, a top panel 103, and a bottom panel 104. The door panel 102 and the sliding device 3 are connected by a through hinge 4. The door panel 102 and the top panel 103 are locked or unlocked by a push-button lock 5. A handle 6 is provided on the outward-facing side of the door panel 102.
[0031] The sliding device 3 includes a base support 301 fixed on the base plate 104. A waste bin seat 302 is fixedly connected to the upper part of the base support 301. A waste bin 2 of appropriate size is placed on the waste bin seat 302. The bottom of the base support 301 is fixed to the base plate 104 through a waste bin seat guide rail 303. The waste bin seat guide rail 303 drives the waste bin seat 302 to slide, thereby driving the waste bin 2 to slide. A reinforcing rib 304 is fixed on each side of the waste bin seat 302. One end of the reinforcing rib 304 is fixed on the waste bin seat guide rail 303, and the other end of the reinforcing rib 304 is fixed on the door panel 102.
[0032] The hollow hinge 4 includes a hollow shaft, which is press-fitted with a fixed blade via a first bushing, and the hollow shaft is clearance-fitted with a movable blade 403 via a second bushing. The fixed side of the fixed blade is fixedly mounted on the sliding device 3, and the fixed side of the movable blade is fixedly mounted on the door panel 102.
[0033] The push-button lock 5 includes a push-button body 501 fixed on the door panel 102. The bottom of the push-button body 501 is connected to the latch by a spring. It also includes a latch hole 502 fixed at a corresponding position on the top plate 103. Under normal conditions, the latch is kept in an extended state by the spring force and engages with the latch hole 502 to maintain the locked state between the door panel 102 and the top plate 103. The diameter of the latch hole 502 is larger than the diameter of the latch.
[0034] In this embodiment, the button lock's workflow is divided into two stages: a locked state and an unlocked state. In the locked state, the cabinet door is closed, the spring is in a naturally extended state, pushing the latch to fully insert into the latch hole on the cabinet body, forming a physical block. The engagement of the latch and the latch hole prevents the cabinet door from opening outward, ensuring sealing and security. The unlocking process is when the button is pressed. The operator applies vertical pressure, and the button moves inward along the axis to unlock. During the pressing of the button, the spring is compressed and stores energy, providing power for resetting. During the resetting process, the operator pushes the cabinet door back into the cabinet body, and the latch is pressed into the latch hole, completing the locking.
[0035] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
