Description
Technical Field
[0001] This utility model relates to the field of insulated boxes, specifically a stackable plastic insulated box. Background Technology
[0002] In the field of insulated box technology, with the increasing demand for insulated product storage and transportation across various industries, the function and structural design of insulated boxes are constantly evolving and improving. However, many insulated boxes on the market still have some unresolved issues regarding the storage and securing of the placement slots. Traditional insulated box placement slot structures are relatively simple, typically relying on simple clips or slots for fixation. This method of fixation makes the placement slots prone to loosening or even detachment when the insulated box is subjected to external impacts or vibrations. For example, during logistics transportation, the bumps and vibrations generated by vehicle movement cause the insulated box to shake continuously. Simple clip structures cannot withstand this external force, leading to collisions and compression of the insulated products within the placement slots, resulting in product damage and affecting product quality and safety.
[0003] However, existing stackable plastic insulated boxes still have some drawbacks in practical use: although some insulated boxes have adopted some improved storage and fixing methods, they are still insufficient in terms of ease of operation and stability. Some insulated boxes require users to perform complicated manual operations to complete the storage and fixing of the placement slots, which not only increases the difficulty and time cost for users, but also makes it easy to make operational errors during operation, resulting in unstable storage.
[0004] To address these issues, we designed a stackable plastic insulated box. Utility Model Content
[0005] The purpose of this invention is to provide a stackable plastic insulated box to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a stackable plastic insulated box, including an outer shell, an insulated box body slidably connected inside the outer shell, a storage chamber inside the insulated box body, a placement slot slidably connected inside the storage chamber, the placement slot being snapped into the storage chamber, a connecting component being provided on the side of the storage chamber away from the placement slot, the placement slot being snapped into the storage chamber through the connecting component, and a lifting component being provided inside the outer shell, the lifting component being located below the insulated box body.
[0007] Furthermore, the connecting assembly includes a horizontal plate, which is fixedly installed on the side of the placement slot near the storage chamber. A pressing block is fixedly connected to the end of the horizontal plate away from the placement slot. A movable plate is provided in the storage chamber, which is slidably connected to the inner side wall of the storage chamber. A pressure block is fixedly connected to the top surface of the movable plate. A baffle is fixedly connected to the inner bottom wall of the storage chamber. The baffle is located on the side of the movable plate near the placement slot and is slidably connected to the movable plate. The movable plate is elastically connected to the inner bottom wall of the storage chamber.
[0008] Furthermore, a first spring is fixedly connected to the bottom surface of the storage chamber, and the other end of the first spring is fixedly installed on the bottom surface of the movable plate.
[0009] Furthermore, a second spring is connected to the inner side wall of the storage chamber, a permanent magnet is fixedly connected to the bottom surface of the movable plate, and an electromagnet is fixedly connected to the inner bottom wall of the outer shell.
[0010] Furthermore, the lifting assembly includes a double-ended threaded rod, which is rotatably mounted on the inner side wall of the outer shell. The double-ended threaded rod has two threaded seats symmetrically threadedly connected to it. Each of the two threaded seats is hinged to a connecting rod, and the two connecting rods are hinged together to a hinge seat. The hinge seat is fixedly mounted on the bottom surface of the insulation box body.
[0011] Furthermore, a drive motor is fixedly connected to one side of the housing, and the output end of the drive motor passes laterally through the outer wall of the housing via a coupling and is fixedly connected to the shaft of the double-threaded rod.
[0012] Furthermore, the pressure block is in contact with the extrusion block.
[0013] Furthermore, the outer shell interlayer is embedded with a removable vacuum plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, when the placement slot is pushed into the storage chamber, the pressing block at the end of the horizontal plate presses down the pressure block and the moving plate together through the mutually fitting inclined surface design. Then, the pressing block is placed on the side of the pressure block away from the baffle. Under the action of the first spring, the pressure block abuts against the bottom of the horizontal plate and cooperates with the baffle, realizing the complete storage and fixation of the placement slot by the insulation box body. This structural design ensures that the placement slot will not shake randomly in the storage state, effectively protecting the insulation product from collision and damage.
[0016] 2. In this utility model, by raising the body of the insulation box, the placement slot will automatically extend outward under the elastic force of the second spring. This automatic extension function avoids the trouble of manually pulling out the placement slot, saves time and manpower, and improves the efficiency of use. Especially when it is necessary to quickly retrieve the insulation product, it can quickly meet the needs. Attached Figure Description

[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 Figures 1-3 This utility model provides a technical solution: a stackable plastic insulated box, including an outer shell 1, an insulated box body 2 slidably connected inside the outer shell 1, a storage chamber 3 opened inside the insulated box body 2, a placement slot 4 slidably connected inside the storage chamber 3, the placement slot 4 can be snapped into the storage chamber 3, a connecting component is provided on the side of the storage chamber 3 away from the placement slot 4, the placement slot 4 is snapped into the storage chamber 3 through the connecting component, a lifting component is provided inside the outer shell 1, the lifting component is located below the insulated box body 2, and a detachable vacuum plate is embedded in the interlayer of the outer shell 1.
[0024] The connecting assembly includes a horizontal plate 5, which is fixedly installed on the side of the placement slot 4 near the storage chamber 3. A pressing block 6 is fixedly connected to the end of the horizontal plate 5 away from the placement slot 4. A movable plate 7 is provided inside the storage chamber 3. The movable plate 7 is slidably connected to the inner side wall of the storage chamber 3. A pressure block 8 is fixedly connected to the top surface of the movable plate 7. A baffle 9 is fixedly connected to the inner bottom wall of the storage chamber 3. The baffle 9 is located on the side of the movable plate 7 near the placement slot 4 and is slidably connected to the movable plate 7. The movable plate 7 is elastically connected to the inner bottom wall of the storage chamber 3. A first spring 10 is fixedly connected to the bottom surface of the storage chamber 3. The other end of the first spring 10 is fixedly installed on the bottom surface of the movable plate 7. The pressure block 8 is in contact with the pressing block 6.
[0025] In practice, when the user places the insulation product into the placement slot 4, the placement slot 4 can be pushed, and the horizontal plate 5 moves into the storage chamber 3. The pressing block 6 at the end of the horizontal plate 5 will press down the pressure block 8 together with the moving plate 7 through the mutually fitting inclined surface design. Then the pressing block 6 will be placed on the side of the pressure block 8 away from the baffle 9. The first spring 10 makes the pressure block 8 abut against the bottom of the horizontal plate 5, cooperating with the baffle 9 to realize the complete storage and fixation of the insulation box body 2 to the placement slot 4.
[0026] See Figure 2 A second spring 11 is connected to the inner wall of the storage chamber 3 via the horizontal plate 5. A permanent magnet 12 is fixedly connected to the bottom surface of the movable plate 7. An electromagnet is fixedly connected to the bottom wall of the outer shell 1. When the body of the insulated box 2 descends into the outer shell 1, the permanent magnet 12 at the bottom of the movable plate 7 is attracted by the electromagnet, causing the movable plate 7 and the pressure block 8 to move down as a whole in the storage chamber 3. The horizontal plate 5 is pushed out of the storage chamber 3 by the elastic force of the second spring 11. After that, if the body of the insulated box 2 is raised, the placement slot 4 will automatically extend outward under the elastic force of the second spring 11.
[0027] See Figure 4 The lifting assembly includes a double-threaded rod 13, which is rotatably mounted on the inner wall of the outer casing 1. Two threaded seats 14 are symmetrically threaded on the double-threaded rod 13. Each threaded seat 14 is hinged to a connecting rod 15. The two connecting rods 15 are hinged together to a hinge seat 16. The hinge seat 16 is fixedly mounted on the bottom surface of the insulation box body 2. A drive motor 17 is fixedly connected to one side of the outer casing 1. The output end of the drive motor 17 passes laterally through the outer wall of the outer casing 1 through a coupling and is fixedly connected to the axis of the double-threaded rod 13.
[0028] When the drive motor 17 is started, the drive shaft of the drive motor 17 drives the double-threaded rod 13 fixedly connected to it to rotate. The rotating double-threaded rod 13 drives the two threaded seats 14 threaded to it to move. The two threaded seats 14 move away from each other, so that the hinge seat 16 moves in the vertical direction, which can drive the insulation box body 2 and the placement slot 4 to descend synchronously. Similarly, when it is necessary to remove the insulation product in the placement slot 4, the drive motor 17 can be driven in the reverse direction, so that the hinge seat 16 based on the double-threaded rod 13 can move upward until the placement slot 4 is completely placed above the top horizontal plane of the outer shell 1.
[0029] Working principle:
[0030] When the drive motor 17 is started, the drive shaft of the drive motor 17 drives the double-threaded rod 13 fixedly connected to it to rotate. The rotating double-threaded rod 13 drives the two threaded seats 14 threaded to it to move. The two threaded seats 14 move away from each other, so that the hinge seat 16 moves in the vertical direction, which can drive the insulation box body 2 and the placement slot 4 to descend synchronously. Similarly, when it is necessary to remove the insulation product in the placement slot 4, the drive motor 17 can be driven in the reverse direction, so that the hinge seat 16 based on the double-threaded rod 13 can move upward until the placement slot 4 is completely placed above the top horizontal plane of the outer shell 1.
[0031] When the user places the insulated product into the placement slot 4, the placement slot 4 can be pushed, and the horizontal plate 5 moves into the storage chamber 3. The pressing block 6 at the end of the horizontal plate 5 will press down the pressure block 8 together with the moving plate 7 through the interlocking inclined surface design. Then the pressing block 6 will be placed on the side of the pressure block 8 away from the baffle 9. The first spring 10 makes the pressure block 8 abut against the bottom of the horizontal plate 5, which cooperates with the baffle 9 to realize the complete storage and fixation of the placement slot 4 by the insulated box body 2. When the insulated box body 2 descends into the outer shell 1, the permanent magnet 12 at the bottom of the moving plate 7 is attracted by the electromagnet, which drives the moving plate 7 and the pressure block 8 to move down as a whole in the storage chamber 3. The horizontal plate 5 is driven by the elastic force of the second spring 11 to push the pressing block 6 out of the storage chamber 3. After that, if the insulated box body 2 is raised, the placement slot 4 will automatically extend outward under the elastic force of the second spring 11.
[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
