[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, and this embodiment provides a fixing structure, which includes a fixing unit 100, the fixing unit 100 includes a supporting plate 101, a threaded rod 102 rotating inside the supporting plate 101, and an extrusion assembly 103 arranged on the side wall of the supporting plate 101.

[0031] When in use, the bearing plate 101 provides installation conditions for the threaded rod 102 and the extrusion assembly 103, and the extrusion assembly 103 is arranged on two adjacent sides of the bearing plate 101, and the number of extrusion assemblies 103 arranged on one side of the bearing plate 101 is at least one, and can be actually adjusted according to the size of the box body 201 to ensure the stability of the first energy storage plate 204 and the second energy storage plate 205.

[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, which is different from the first embodiment in that: it also includes two adjacent side walls of the supporting plate 101, respectively fixedly connected with the first baffle 101a and the second baffle 101b, the first baffle 101a is adjacent to the second baffle 101b, and the extrusion assembly 103 is arranged on the two side surfaces of the supporting plate 101 to which the first baffle 101a and the second baffle 101b are fixed.

[0034] Furthermore, a placement groove 101c is provided in the carrier plate 101, first grooves 101d are provided on both sides of the carrier plate 101, and through grooves 101e are provided on the sides of the first grooves 101d, and the through grooves 101e are connected to the placement grooves 101c.

[0035] By setting the first baffle 101a and the second baffle 101b, the first energy storage plate 204 and the second energy storage plate 205 can be limited to prevent the first energy storage plate 204 and the second energy storage plate 205 from moving. The first baffle 101a and the second baffle 101b are adjacent to each other and there is a 90-degree angle between them, so that the first baffle 101a and the second baffle 101b can increase the contact area when they contact with the first energy storage plate 204 or the second energy storage plate 205, so as to prevent the first energy storage plate 204 and the second energy storage plate 205 from moving. The first energy storage plate 204 or the second energy storage plate 205 provides protection. If the first baffle plate 101a, the second baffle plate 101b and the side surface of the carrier plate 101 present a certain angle, the contact area between the first energy storage plate 204 and the second energy storage plate 205 will be reduced. When the box body 201 is subjected to an impact, the first energy storage plate 204 and the second energy storage plate 205 may be concave inward. The opening of the first groove 101d and the through groove 101e provides placement conditions for the extrusion assembly 103.

[0036] Specifically, one end of the threaded rod 102 is rotatably connected to one side of the placement groove 101c, and the other end of the threaded rod 102 passes through the placement groove 101c. The movable sleeve of the threaded rod 102 is provided with a moving block 102a, and the moving block 102a is threadedly matched with the threaded rod 102.

[0037] By rotating the threaded rod 102 through one end of the placement groove 101c, the moving block 102a can be driven to move. When the threaded rod 102 moves, it will contact the inclined surface of the push plate 103b, and push the push plate 103b to drive the extrusion plate 103a to fix the first energy storage plate 204 and the second energy storage plate 205. The number of moving blocks 102a is set to be the same as the number of extrusion assemblies 103 on one side of the carrier plate 101.

[0038] Specifically, the extrusion assembly 103 includes an extrusion plate 103a, a push plate 103b arranged on one side of the extrusion plate 103a, and four return springs 103c arranged on both sides of the push plate 103b. The inner circle of the return spring 103c is provided with a telescopic rod 103d, and the push plate 103b is slidably matched with the moving block 102a.

[0039] Furthermore, the extrusion plate 103a slides in the first groove 101d, the push plate 103b slides with the through groove 101e, the two ends of the return spring 103c are respectively fixed to one side of the extrusion plate 103a and one side of the first groove 101d, and the two ends of the telescopic rod 103d are respectively fixed to one side of the extrusion plate 103a and one side of the first groove 101d.

[0040] By setting the return spring 103c, when the operating threaded rod 102 is rotated to drive the moving block 102a to move, the thrust on the push plate 103b is eliminated and the extrusion plate 103a can be driven to return to its original position. The movement of the extrusion plate 103a can be limited by the setting of the telescopic rod 103d, and the movement of the extrusion plate 103a is also limited by the sliding cooperation between the push plate 103b and the through groove 101e, thereby ensuring the normal operation of the extrusion plate 103a.

[0041] Specifically, a fixing plate 103a-1 is fixedly connected to the midline of one side of the extrusion plate 103a, and sliding blocks 103a-2 are symmetrically fixedly connected to the top and bottom of the fixing plate 103a-1.

[0042] Furthermore, a second groove 103b-1 is provided on one side of the push plate 103b close to the extrusion plate 103a, and two sliding grooves 103b-2 are symmetrically provided on the upper and lower sides of the second groove 103b-1. The sliding groove 103b-2 is slidably matched with the slider 103a-2. A spring damper 103b-3 is provided in the second groove 103b-1, and two ends of the spring damper 103b-3 are respectively fixed to one side of the second groove 103b-1 and one side of the fixed plate 103a-1.

[0043] The sliding cooperation between the slider 103a-2 and the slide groove 103b-2 can ensure the limiting of the extrusion plate 103a, and the sliding cooperation between the fixing plate 103a-1 and the second groove 103b-1, as well as the setting of the spring damper 103b-3, can ensure that the extrusion plate 103a fixes the first energy storage plate 204 and the second energy storage plate 205, and can also reduce the shock of the first energy storage plate 204 and the second energy storage plate 205 when the box body 201 is hit by an external force or accidentally falls, thereby protecting the first energy storage plate 204 and the second energy storage plate 205, and can effectively prevent the first energy storage plate 204 and the second energy storage plate 205 from being damaged or leaking when the box body 201 is hit by an external force or accidentally falls, thereby ensuring the safety of the transported items.

[0044] When in use, first, when transporting an object, it is necessary to understand whether the object is suitable for a low-temperature environment or a high-temperature environment, and then prepare a suitable first energy storage plate 204 and a second energy storage plate 205. When installing the first energy storage plate 204 and the second energy storage plate 205, firstly, the two first energy storage plates 204 and the two second energy storage plates 205 are symmetrically placed in the space between the inner wall of the box body 201 and the first baffle plate 101a and the second baffle plate 101b, and the first energy storage plate 204 and the second energy storage plate 205 are limited by the first baffle plate 101a and the second baffle plate 101b in the first step, and then the four threaded rods 102 are rotated respectively. When the threaded rods 102 rotate, the moving block 102a will be driven to move downward. During the movement of the moving block 102a, it will contact with the push plate 103b. The inclined side makes contact, and then the moving block 102a continues to move, pushing the push plate 103b to move out of the first groove 101d. Since the elastic force of the return spring 103c is smaller than the elastic force of the spring damper 103b-3, the movement of the push plate 103b will drive the movement of the extrusion plate 103a, and at this time the return spring 103c will be stretched. When the extrusion plate 103a contacts the first energy storage plate 204 or the second energy storage plate 205, continuing to move the moving block 102a will compress the spring damper 103b-3. At this time, the thrust of the spring damper 103b-3 on the extrusion plate 103a makes the first energy storage plate 204 or the second energy storage plate 205 more stably fixed; when disassembly is required, only the threaded rod 102 needs to be rotated in the opposite direction.

[0045] Example 3

[0046] Reference Figure 5-6 , which is the third embodiment of the utility model, and is based on the first two embodiments. This embodiment provides a constant temperature box, which includes a transport unit 200, and the transport unit 200 includes a box body 201, a box cover 202, a control component 203 installed on one side of the box body 201, and two first energy storage plates 204 and two second energy storage plates 205 arranged inside the box body 201. The fixing unit 100 is installed at the four corners inside the box body 201, the first energy storage plate 204 and the second energy storage plate 205 are both adapted to the fixing unit 100, and the two first energy storage plates 204 and the two second energy storage plates 205 are symmetrically arranged. A temperature sensor is installed at the bottom of the box body 201, and the box body 201 and the box cover 202 are rotatably connected by hinges.

[0047] Through the setting of the control component 203, the temperature in the box 201 can be monitored through the temperature sensor in the box 201, and the temperature threshold can be set through the control component 203. When the temperature in the box 201 is lower than or higher than the threshold, the control component 203 will sound an alarm to remind the staff to avoid damage to the transported objects. The control component 203, the temperature sensor, and the alarm module and control module involved are all existing technologies and will not be described in detail here.

[0048] Specifically, a first filling port 204a is provided on one side of the first energy storage plate 204, a first support column 204b is fixedly connected inside the first energy storage plate 204, a second filling port 205a is provided on one side of the second energy storage plate 205, and a second support column 205b is fixedly connected inside the second energy storage plate 205.

[0049] The first energy storage plate 204 and the second energy storage plate 205 can be designed according to different sizes of the box 201, and the first filling port 204a and the second filling port 205a can be sealed by means of rotation welding or the like. In addition, the phase change materials of different temperatures and types used in the first energy storage plate 204 and the second energy storage plate 205 are also prior art and will not be elaborated on herein. The first energy storage plate 204 and the second energy storage plate 205 can be made of different materials to ensure that they do not chemically react with the phase change materials placed therein. In this way, objects meeting different temperature environments can be transported and the quality of the objects can be ensured during transportation.

[0050] Phase change materials of different temperatures and types can be selected and injected into the first energy storage plate 204 and the second energy storage plate 205 from the first filling port 204a and the second filling port 205a, respectively. The first filling port 204a and the second filling port 205a are then sealed by a rotary welding device or other methods to prefabricate the first energy storage plate 204 and the second energy storage plate 205 suitable for different application scenarios.

[0051] The shapes of the first support column 204b and the second support column 205b are not necessarily cylindrical, and may be other shapes or forms, such as hollow cylinders, reinforcing ribs, etc. The purpose of designing the first support column 204b and the second support column 205b is to ensure the structural strength of the first energy storage plate 204 and the second energy storage plate 205 so that they will not be easily broken due to external impact.

[0052] In addition, in addition to utilizing the extrusion assembly 103 for shock absorption, the first energy storage plate 204 and the second energy storage plate 205 are provided with rubber pads or pads that can protect the first energy storage plate 204 and the second energy storage plate 205, thereby increasing the protection capability of the first energy storage plate 204 and the second energy storage plate 205, on the extrusion plate 103a, the first baffle plate 101a, the second baffle plate 101b, and the surrounding and bottom surfaces of the box body 201 that are in contact with the first energy storage plate 204 and the second energy storage plate 205.

[0053] In summary, when in use, it is necessary to select the first energy storage plate 204 and the second energy storage plate 205 with corresponding phase change materials encapsulated therein according to the temperature environment requirements of the items to be transported, and after sufficient pre-heating or sufficient cooling, place the first energy storage plate 204 and the second energy storage plate 205 around the box body 201, and install and fix the first energy storage plate 204 and the second energy storage plate 205 according to the operation process of the fixing unit 100 mentioned in Example 2, which also facilitates the replacement of the first energy storage plate 204 and the second energy storage plate 205.
