Description

Technical Field

[0001] This utility model relates to the field of thermal insulation box technology, specifically a thermal insulation box using heat insulation materials. Background Technology

[0002] Insulated boxes can keep items inside warm and are widely used in food, medical and other fields. In the food industry, they can keep food fresh, inhibit bacterial growth, and extend shelf life. In the medical field, they can ensure that vaccines do not become ineffective during transportation and that blood products do not deteriorate, thus ensuring medical safety. During the use of insulated boxes, especially in food delivery, they need to be able to open and close quickly to improve work efficiency. For example, application number 202322734022.8, filed on [date], describes an insulated box with a latching mechanism. During use, it can achieve rapid opening and closing while ensuring structural stability and good sealing, making it more suitable for scenarios requiring rapid and automated opening and closing.

[0003] However, during use, after the lid is released from its locked state, it may become stuck when opened due to material damage or hinge aging. The device in the above application does not have an auxiliary opening structure during use, resulting in low working efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an insulated box using thermal insulation material to solve the problem mentioned in the background art that it lacks an auxiliary opening structure and has low working efficiency during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulated box using thermal insulation material, comprising an outer box, an inner box being disposed inside the outer box, an auxiliary frame being fixedly connected to the upper surface of the inner box, and a box cover being rotatably disposed on the upper surface of the inner box; a handle being disposed on the outer wall of the outer box; an inner connecting block being disposed inside the inner box, and a button being movably disposed inside the inner connecting block; a push rod being slidably disposed inside the inner box; and a rotating shaft being rotatably disposed inside the auxiliary frame.

[0006] Preferably, the inner box is made of vacuum insulation material, the front surface of the box cover is concave, and a mating plate is fixedly connected to the groove of the box cover, and the surface of the mating plate is inclined.

[0007] Preferably, a lever is fixedly connected to the inner wall of the button, and the end of the lever is located outside the inner block, and the end of the lever is inclined.

[0008] Preferably, a reset spring that provides elastic reset is fixedly connected to the surface of the paddle, and the other side of the reset spring is fixedly connected to the inner wall of the inner block.

[0009] Preferably, a base plate is fixedly connected to the lower surface of the push rod, and a connecting spring that plays an elastic restoring role is fixedly connected to the upper surface of the base plate, and the other side of the connecting spring is fixedly connected to the bottom of the inner box.

[0010] Preferably, the push rods are symmetrically distributed on both sides of the inner housing.

[0011] Preferably, the rotating shaft is fixedly connected to the box cover, and the rotating shaft is symmetrically distributed on both sides of the box cover. A torsion spring is fixedly connected to the surface of the rotating shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the auxiliary frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the insulated box using thermal insulation material adopts a novel structural design, the specific details of which are as follows:

[0013] This insulated box, made of thermal insulation material, requires the lid to be closed during use. Rotating the lid downwards causes the mating plate on the inner wall of the lid to contact the paddle inside the inner connecting block. Since both the lower surface of the mating plate and the upper surface of the paddle are inclined, the paddle is pushed towards the direction of the return spring. After the lid is rotated to a horizontal position, the mating plate and the paddle no longer contact each other. The paddle then returns to its original position under the action of the return spring, locking the mating plate in place and closing the lid. The operation is simple, convenient, and highly efficient.

[0014] When the insulated box using thermal insulation material needs to be opened, press the button. The button will move the lever to the inside of the inner connecting plate. When the lever moves to a position where it no longer contacts the connecting plate, the lid and the inner box are no longer locked. At this point, the lid can be opened. The operation of opening the lid is simple and efficient.

[0015] This insulated box, made with thermal insulation material, features a push rod that moves as the lid closes, causing the base plate to descend. During this process, a connecting spring is stretched. The connecting spring remains stretched while the lid is closed. Conversely, when the lid is opened, the push rod rises under the action of the connecting spring, thus assisting in disassembly and ensuring a smooth, unobstructed opening of the lid.

[0016] Furthermore, during the closing process of the lid, the lid will drive the rotating shaft to rotate inside the auxiliary frame. At this time, the torsion spring will be stretched. Then, during the opening process of the lid, the torsion spring will drive the rotating shaft to rotate back. At this time, the torsion spring also plays an auxiliary role in opening, optimizing the smoothness of the lid opening and improving work efficiency. Attached Figure Description

[0025] 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.

[0026] This utility model provides the following technical solution: an insulated box using heat insulation material.

[0027] Example 1: The mating plate 8 and the lever 13 allow the lid 2 and inner box 3 to quickly engage, as shown below. Figures 1-3 as well as Figure 6 As shown, it includes an outer box 1, an inner box 3 is provided inside the outer box 1, and an auxiliary frame 4 is fixedly connected to the upper surface of the inner box 3, and a box cover 2 is rotatably provided on the upper surface of the inner box 3; a handle 5 is provided on the outer wall of the outer box 1; an inner connecting block 6 is provided inside the inner box 3; the inner box 3 is made of vacuum heat insulation material, the front surface of the box cover 2 is concave, and a mating plate 8 is fixedly connected to the groove of the box cover 2, and the surface of the mating plate 8 is inclined.

[0028] A lever 13 is fixedly connected to the inner wall of button 7, and the end of lever 13 is located outside the inner block 6. The end of lever 13 is inclined. A reset spring 14 for elastic reset is fixedly connected to the surface of lever 13. The other side of reset spring 14 is fixedly connected to the inner wall of inner block 6. A base plate 11 is fixedly connected to the lower surface of push rod 10. A connecting spring 12 for elastic reset is fixedly connected to the upper surface of base plate 11. The other side of connecting spring 12 is fixedly connected to the bottom of inner box 3.

[0029] During use, when the lid 2 needs to be closed, rotate the lid 2 downwards. The mating plate 8 on the inner wall of the lid 2 will contact the paddle 13 inside the inner block 6. Since the lower surface of the mating plate 8 and the upper surface of the paddle 13 are both inclined, the paddle 13 will be pushed by the mating plate 8 and move towards the direction of squeezing the return spring 14. After the lid 2 is rotated to the horizontal position, the mating plate 8 and the paddle 13 will no longer be in contact. At this time, the paddle 13 will return to its original position under the action of the return spring 14, and then the paddle 13 will lock the mating plate 8, thus closing the lid 2. The operation process is simple and convenient, and the work efficiency is high.

[0030] Example 2: Unlike Example 1, the button 7 allows the paddle 13 to move inward into the inner connector 6, preventing the connector plate 8 from being stuck. Figure 6 As shown, the inner connecting block 6 has a button 7 that is movable inside. When it is necessary to open the box cover 2, press the button 7. At this time, the button 7 drives the lever 13 to move to the inner position of the inner connecting block 6. When the lever 13 moves to a position where it does not contact the docking plate 8, the box cover 2 and the inner box 3 are not in a locked state. At this time, the box cover 2 can be opened. The operation of opening the box cover 2 is simple and efficient.

[0031] Example 3: Unlike Example 2, the push rod 10, connecting spring 12, and torsion spring 15 allow the lid 2 to open quickly without jamming. Figures 4-7 As shown, a push rod 10 is slidably arranged inside the inner box 3; the push rod 10 is symmetrically distributed on both sides of the inner box 3; a rotating shaft 9 is rotatably arranged inside the auxiliary frame 4; the rotating shaft 9 is fixedly connected to the box cover 2; the rotating shaft 9 is symmetrically distributed on both sides of the box cover 2; a torsion spring 15 is fixedly connected to the surface of the rotating shaft 9; and the other side of the torsion spring 15 is fixedly connected to the inner wall of the auxiliary frame 4.

[0032] During the closing process of the lid 2, the surface of the lid 2 pushes the push rod 10, causing the push rod 10 to lower the base plate 11. At this time, the connecting spring 12 is stretched. That is, when the lid 2 is in the closed state, the connecting spring 12 is always stretched. When the lid 2 is opened, the push rod 10 will rise under the action of the connecting spring 12. At this time, the push rod 10 plays an auxiliary role in disassembly, allowing the lid 2 to open smoothly without jamming. During the closing process of the lid 2, the lid 2 will drive the rotating shaft 9 to rotate inside the auxiliary frame 4. At this time, the torsion spring 15 will be stretched. Then, during the opening process of the lid 2, the torsion spring 15 will drive the rotating shaft 9 to rotate back. At this time, the torsion spring 15 also plays an auxiliary role in opening, optimizing the smoothness of the lid 2 opening and improving work efficiency.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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.
