Description

Technical Field

[0001] This utility model belongs to the field of waste household appliance dismantling technology, and in particular relates to a sliding door type storage cage with multiple locking devices. Background Technology

[0002] With the rapid development of the waste home appliance recycling and processing industry, various parts generated during dismantling need to be classified, temporarily stored, and transferred. Storage cages, as a common logistics storage device, are widely used for the centralized storage and management of dismantled parts.

[0003] Existing storage cages mostly use double doors that need to swing outwards when opened, occupying external space. In the narrow dismantling workshop, this can easily hinder the passage of personnel and equipment, reducing work efficiency and space utilization. Even if simple sliding doors are used, the bottom groove of the door lacks effective protection, which can easily accumulate dust, debris and other foreign objects, increasing the door's movement resistance and component wear, and shortening the equipment's lifespan. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a sliding door type storage cage with a multiple locking device, which includes a storage cage body, a frame provided on the side wall of the storage cage body, a first sliding door and a second sliding door provided inside the frame, a synchronization mechanism provided at the bottom of the first sliding door and the second sliding door, the synchronization mechanism including a first connecting block, a first chain provided on the side wall of the first connecting block, a first gear meshing inside the first chain, and a second connecting block provided at the opposite end of the first chain; The first sliding door has a third connecting block at its bottom, a second chain on its side wall, a second gear inside the second chain, and a fourth connecting block at the opposite end of the second chain.

[0005] In one example, the first connecting block is located at the bottom of the first sliding door, the third connecting block is located at the bottom of the first sliding door, the second connecting block is located at the bottom of the second sliding door, and the fourth connecting block is located at the bottom of the second sliding door, and they are distributed at the four corners.

[0006] In one example, the first chain is paired with the first gear, the second chain is paired with the second gear, and the first chain and the first gear are positioned above the second chain and the second gear.

[0007] In one example, both the first gear and the second gear are rotatably mounted at the bottom of the frame, and the first gear and the second gear are slidably mounted at the bottom of the second sliding door and the first sliding door, respectively.

[0008] In one example, a storage rack is provided at the middle of the frame, and a rotating column is installed through and rotatably inside the storage rack, with a shielding plate provided on the side wall of the rotating column.

[0009] In one example, the shielding plate is connected to the first sliding door and the second sliding door respectively, and the rotating column is also rotatably installed inside the frame. The side wall of the rotating column is provided with a torsion spring, which is located inside the frame and its two ends are connected to the frame and the rotating column respectively.

[0010] The sliding door type storage cage with multiple locking devices proposed in this utility model can bring the following beneficial effects: 1. This utility model uses a synchronization mechanism of chain and gear to replace the belt pulley that is prone to aging and falling off, which can avoid transmission failure after long-term use; at the same time, the power is evenly transmitted through the connecting blocks distributed at the four corners, ensuring that the first sliding door and the second sliding door move synchronously in opposite directions without jamming or deviation. This not only makes it convenient for operators to quickly pick up and put away disassembled parts of old household appliances, but also reduces the maintenance frequency and cost of transmission components.

[0011] 2. This utility model features a concealing plate inside the storage rack that extends with the sliding door, effectively blocking the frame's sliding groove and preventing dust, debris, and other foreign objects from entering and causing sliding jams or component wear. Furthermore, the concealing plate, with the help of a rotating column and a torsion spring, automatically retracts into the storage rack when the door closes, eliminating the need for manual operation. This protects the sliding groove and door structure, extends the lifespan of the storage cage, and improves ease of use. Combined with the support of the frame and the storage cage's internal storage function, it also ensures that internal parts remain uncontaminated. Attached Figure Description

Detailed Implementation

[0019] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0020] Example: like Figures 1-6 As shown, an embodiment of this utility model proposes a sliding door type storage cage with a multiple locking device, which includes a storage cage body 11. The storage cage body 11 is used to store parts and other items after dismantling waste home appliances, providing dedicated storage space for dismantled waste home appliance parts to prevent parts from being scattered and lost, and at the same time facilitating centralized management and inventory of parts. A frame 12 is provided on the side wall of the storage cage body 11 to provide an installation carrier and support structure for the first sliding door 13, the second sliding door 14 and the synchronization mechanism, ensuring the stability of the installation position of each component, and at the same time, the sliding door... The movement serves as a guide. When in use, pulling the first sliding door 13 and the second sliding door 14 inside the frame 12 opens and closes the storage cage, facilitating the operation of operators to retrieve and place internal parts. When closed, the internal parts are protected from external dust or debris. The synchronization mechanism at the bottom of the first sliding door 13 and the second sliding door 14 ensures that the sliding doors move synchronously in opposite directions, ensuring that the two sliding doors move in a coordinated manner. This avoids damage to the door body caused by one-sided jamming or asynchronous movement, and improves the smoothness and efficiency of the door opening and closing.

[0021] When the door needs to be opened, the first sliding door 13 will begin to open. At this time, the first connecting block 15 at the bottom of the first sliding door 13 will pull the first chain 16 to move. As the connection medium between the first sliding door 13 and the first chain 16, the opening power of the first sliding door is transmitted to the first chain 16, realizing effective power transmission. The first chain 16 is set on the side wall of the first gear 17 and meshes with the first gear 17. Through the meshing transmission with the first gear 17, the power transmission is ensured to be stable and non-slipping. At the same time, the support of the gear limits the movement trajectory of the chain and prevents the chain from deviating or falling off. The first chain 16 will move along the first gear 17, thereby pulling the second... The second connecting block 18 at the bottom of the sliding door 14 moves in the opposite direction. The linear movement of the chain transmits power to the second connecting block 18, realizing the conversion of power direction and providing power for the reverse movement of the second sliding door 14. The second connecting block 18 also causes the second sliding door 14 to move in the opposite direction, receiving the power transmitted by the first chain 16 and converting the power into the motion force of the second sliding door 14, realizing the synchronous opening of the two doors in opposite directions. The first sliding door 13 and the second sliding door 14 are respectively retracted into the frame 12. By retracting into the frame, the door body is hidden and stored, avoiding the door body from protruding and occupying extra space, and reducing the risk of the door body being damaged by external collisions, thereby realizing the action of opening the door.

[0022] When closing is required, the first sliding door 13 begins to close. At this time, the third connecting block 19 at the bottom of the first sliding door 13 pulls the second chain 21 to move. As the connecting component between the first sliding door 13 and the second chain 21, it transmits the closing power of the first sliding door to the second chain 21, providing a power transmission channel for the closing action. The second chain 21 is set on the side wall of the second gear 22 and meshes with the second gear 22. Utilizing the meshing relationship with the second gear 22, it ensures stable transmission of closing power, prevents the chain from slipping or deviating during transmission, and ensures transmission accuracy. The second chain 21 will move along the second gear 22, thereby causing the second chain 21 to pull... The fourth connecting block 23 at the bottom of the second sliding door 14 moves in the opposite direction. The closing power is transmitted to the fourth connecting block 23 through chain transmission, realizing the effective transmission and direction conversion of power. This causes the second sliding door to move in the opposite direction. The fourth connecting block 23 also causes the second sliding door 14 to move in the opposite direction. It receives the power from the second chain 21 and transmits it to the second sliding door 14, driving the second sliding door to close synchronously in the opposite direction with the first sliding door. This ensures that the closing action is coordinated. The first sliding door 13 and the second sliding door 14 extend from inside the frame 12 respectively. By extending out of the frame, the door body blocks the opening of the storage cage, completing the closing action and protecting the internal parts, thereby realizing the closing action.

[0023] The first connecting block 15, the third connecting block 19, the second connecting block 18, and the fourth connecting block 23 are respectively installed at the bottom of the first sliding door 13 and the second sliding door 14, arranged in a four-corner distribution. This ensures that the force points of the two sliding doors are evenly distributed at the four bottom corners, preventing excessive force on a single connection point and thus avoiding damage to components. This improves the stability and service life of the connection between the door body and the transmission mechanism. The first connecting block 15 and the second connecting block 18 are connected to the first chain 16, and the third connecting block 19 and the fourth connecting block 23 are connected to the second chain 21, forming two independent transmission connection structures, corresponding to the opening and closing actions respectively. This ensures that the power transmission of the two actions does not interfere with each other, improving transmission reliability. Furthermore, the use of chains and gears instead of belts and pulleys prevents the belt from stretching over time and falling off the pulley, improving the durability and stability of the transmission structure and avoiding transmission failures caused by belt aging and stretching. To prevent dynamic failure, reduce equipment maintenance frequency, and lower operating costs, the first chain 16 and the first gear 17 are matched with each other, and the second chain 21 and the second gear 22 are matched with each other to ensure the meshing accuracy of the chain and gear, reduce wear during transmission, improve power transmission efficiency, and avoid jamming or component damage caused by size mismatch. The first chain 16 and the first gear 17 are located above the second chain 21 and the second gear 22 through a layered layout, making reasonable use of the space at the bottom of the frame and avoiding spatial overlap between the two transmission mechanisms. The first gear 17 and the second gear 22 are rotatably set at the bottom of the frame 12, and the first gear 17 and the second gear 22 are slidably installed at the bottom of the second sliding door 14 and the first sliding door 13, respectively. Thus, they do not interfere with each other during use, ensuring that the two sets of gears will not collide or interfere with each other when moving with the sliding door, and ensuring that the opening and closing actions can be carried out smoothly.

[0024] Meanwhile, when the first sliding door 13 and the second sliding door 14 are opened, the cover plate 26 inside the storage rack 24 will be pulled out along with the first sliding door 13 and the second sliding door 14, providing storage space for the cover plate 26. This prevents the cover plate from being exposed and damaged when idle, and ensures the stability of the movement trajectory when the cover plate is pulled out. At this time, the cover plate 26 will cover the slide groove of the frame 12, preventing foreign objects from entering the slide groove and preventing dust, debris and other foreign objects from entering the slide groove. This avoids foreign objects causing the sliding door to slide and jam or the slide groove to wear, and extends the service life of the slide groove and the sliding door. At the same time, when the cover plate 26 is pulled out, the cover plate 26 will drive the rotating column 2 5. The rotation converts the linear motion of the shield into the rotational motion of the rotating column, providing power for the torsion spring 27 to store elastic potential energy. The rotating column 25 will drive the torsion spring 27 to rotate and generate torsional force. As the mounting and power transmission component of the torsion spring 27, it drives the torsion spring to rotate to store elastic potential energy, preparing for the automatic retraction of the shield. When the first sliding door 13 and the second sliding door 14 are closed, the torsion spring 27 releases the torsional force, and the rotating column 25 rotates in the opposite direction, retracting the shield 26. By releasing the torsional force, it provides the rotating column with reverse rotational power, thereby driving the shield to automatically retract into the storage rack without manual operation, improving the convenience of use.

[0025] The rotating column 25 is installed inside the storage rack 24 and rotates through it. The rotating column 25 is also installed inside the frame 12 to provide double rotation support for the rotating column, ensuring that the rotating column is stable and does not wobble when rotating, and ensuring that the action of pulling out and retracting the cover is smooth. The torsion spring 27 is also installed inside the frame 12 to provide a stable installation environment for the torsion spring, avoiding damage to the torsion spring from external collisions or dust, and ensuring the stable function of the torsion spring.
