Description

Technical Field

[0001] This utility model relates to the field of cryogenic chamber technology, specifically a prefabricated cryogenic chamber. Background Technology

[0002] In food processing, pharmaceutical storage, and scientific research, cryogenic storage equipment is crucial for ensuring the quality and performance of goods. Traditional cryogenic warehouses typically employ fixed or integrated structures, with their capacity determined during manufacturing. They primarily achieve cryogenic environmental control through a combined insulated enclosure and refrigeration system. While these warehouses were initially widely used due to their structural stability and direct cooling effect, their inherent design limitations have become increasingly apparent with the diversification of modern warehousing needs, particularly the increasing prevalence of small-batch, multi-transportation scenarios, temporary expansion, and cross-site transfers.

[0003] Existing fixed cryogenic chambers have a fixed volume, which leads to a contradiction when the number of stored items fluctuates significantly: "small-capacity chambers are insufficient, while large-capacity chambers are left empty and wasted." If temporary expansion is needed, new equipment must be purchased, which not only increases initial investment costs but also wastes idle equipment resources and cannot meet dynamic storage needs. Furthermore, when the chamber expands and contracts due to temperature changes or when tiny gaps appear due to assembly errors, cold air can easily escape from these gaps, affecting the chamber's insulation performance. Therefore, a prefabricated cryogenic chamber is needed to solve the problems existing in the current technology. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated cryogenic chamber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated cryogenic chamber, comprising a main cryogenic chamber, with auxiliary assembly chambers on both sides of the main cryogenic chamber, a sealing plate on the side of the auxiliary assembly chamber away from the main cryogenic chamber, and clamping mechanisms at the front and rear of the main cryogenic chamber, the clamping mechanism comprising an adjusting sliding shell, a first clamping arm, and a second clamping arm, the adjusting sliding shell being fixed in a groove of the main cryogenic chamber, the first clamping arm and the second clamping arm being slidably connected in a groove of the adjusting sliding shell, and the second clamping arm being symmetrically arranged on one side of the first clamping arm.

[0006] Preferably, a bidirectional threaded rod is provided between the bearings on both ends of the adjusting slide housing, and an adjusting knob is fixed in the middle section of the bidirectional threaded rod.

[0007] Preferably, the bidirectional threaded bar thread passes through the interior of the first clamping arm and the second clamping arm, and one end of the first clamping arm and the second clamping arm extends toward the sealing plate.

[0008] Preferably, a second groove is provided on one end face of the main cryogenic chamber, and a second sealing block is fixed on the other end face of the main cryogenic chamber.

[0009] Preferably, a first groove is provided on one end face of the sub-assembly compartment, and a first sealing block is fixed on the other end face of the sub-assembly compartment.

[0010] Preferably, the upper end of the main cryogenic chamber is provided with a sealing cover, and the inner bottom wall of the main cryogenic chamber is provided with a refrigeration unit for controlling the temperature conditions inside the chamber.

[0011] This utility model provides a prefabricated cryogenic chamber, which has the following advantages compared with the prior art:

[0012] The modular design of the main cryogenic chamber and auxiliary assembly chambers allows for flexible adjustment of the total capacity based on the actual number of items to be stored. When there are few items, the main cryogenic chamber can be used independently; when more items require more space, simply unlocking the clamping mechanism and adding auxiliary assembly chambers to both sides of the main cryogenic chamber expands the storage space without the need to purchase additional equipment, greatly improving the flexibility and economy of the equipment.

[0013] The clamping mechanism employs a combination of a bidirectional threaded rod and an adjustment knob. Simply rotating the adjustment knob controls the opening and closing of the first and second clamping arms, clamping or unlocking the sealing plate, thereby completing the installation and fixation of the sub-assembly chamber. The entire process requires no complex tools or professional skills, is simple and intuitive to operate, significantly reducing assembly difficulty and allowing non-professionals to quickly get started. The device ensures the stability of the low-temperature environment inside the chamber through a multi-layer sealing structure: the main low-temperature chamber and the sub-assembly chamber form a preliminary seal through the interlocking of the first groove and the first sealing block, and the second groove and the second sealing block; after the clamping mechanism drives the clamping arms to clamp the sealing plate, the overall sealing performance is further enhanced, effectively reducing the escape of cold air from the chamber.

[0014] The main cryogenic chamber, auxiliary assembly chamber, sealing plates, and other components adopt a modular design, allowing for disassembly and transportation, reducing transport space requirements, and making them particularly suitable for handling and installation in complex environments. Furthermore, each component has an independent structure; if a component is damaged, it can be replaced individually, reducing maintenance costs and difficulty, and extending the overall lifespan of the equipment.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a prefabricated cryogenic chamber. The core structure of the prefabricated cryogenic chamber includes a main cryogenic chamber 1, with auxiliary assembly chambers 2 assembled on both sides. A sealing plate 3 is provided on the side of the auxiliary assembly chamber 2 away from the main cryogenic chamber 1. To achieve a stable connection of each component, a clamping mechanism 4 is provided at the front and rear of the main cryogenic chamber 1. This mechanism consists of an adjusting sliding shell 5, a first clamping arm 6, and a second clamping arm 7. The adjusting sliding shell 5 is fixed in a groove in the main cryogenic chamber 1. The first clamping arm 6 and the second clamping arm 7 are slidably connected in the sliding groove of the adjusting sliding shell 5, and the second clamping arm 7 is symmetrically distributed on one side of the first clamping arm 6. When it is necessary to expand the storage space of the cryogenic chamber, the first clamping arm 6 and the second clamping arm 7 are first controlled to move away from each other, and the sealing plates 3 at both ends of the main cryogenic chamber 1 are unlocked. Subsequently, the auxiliary assembly chambers 2 are inserted into the gaps between the two ends of the main cryogenic chamber 1 and the sealing plates 3, so that the first sealing block 11 of one auxiliary assembly chamber 2 is embedded in the second groove 12 of the main cryogenic chamber 1, and the first groove 10 of the other auxiliary assembly chamber 2 is fitted onto the second sealing block 13 of the main cryogenic chamber 1. Next, the sealing plates 3 are used to seal one end of the corresponding auxiliary assembly chamber 2, and finally the clamping openings of the first clamping arm 6 and the second clamping arm 7 are adjusted until the two clamp the sealing plates 3 at both ends. Through this operation, the two auxiliary assembly chambers 2 can be sealed and combined with the main cryogenic chamber 1, realizing the flexible expansion of the cryogenic chamber space;

[0022] The advantages of this design are significant: First, the total capacity can be flexibly adjusted according to the actual number of items. When the number of items increases, only the auxiliary assembly compartment 2 needs to be added, without the need to purchase new equipment. Second, the expansion operation is simple. Installation and fixation can be completed by controlling the opening and closing of the clamping arms through the adjustment knob 9, without the need for complicated tools or professional skills. Third, the sealing performance is excellent. During assembly, the cooperation of the first sealing block 11 and the second groove 12, and the first groove 10 and the second sealing block 13 form a multi-seal structure. In addition, the design of the clamping arms clamping the sealing plate 3 can effectively reduce the heat exchange between the inside and outside of the compartment. Whether used independently or combined for expansion, it can ensure good low-temperature storage effect.

[0023] Further integration Figure 1 , Figure 2 and Figure 4 It is known that a bidirectional threaded rod 8 is installed between the bearings on both ends of the adjusting slide 5. The middle section of the bidirectional threaded rod 8 is fixed with an adjusting knob 9. Rotating the adjusting knob 9 can drive the bidirectional threaded rod 8 to rotate. Before use, the bidirectional threaded rod 8 is rotated by the adjusting knob 9. Since the surface of the bidirectional threaded rod 8 has symmetrical bidirectional spiral patterns, and the first clamping arm 6 and the second clamping arm 7 are respectively located on the two spiral patterns of the bidirectional threaded rod 8, rotating the bidirectional threaded rod 8 will drive the first clamping arm 6 and the second clamping arm 7 to move closer or further apart. When the two move closer together, they can clamp the sealing plates 3 at both ends of the main cryogenic chamber 1, so that the sealing plates 3 seal the side ports of the main cryogenic chamber 1. At this time, the main cryogenic chamber 1 can be used independently.

[0024] from Figure 4 As can be seen more clearly, the double-threaded bar 8 is threaded through the interior of the first clamping arm 6 and the second clamping arm 7, and one end of the first clamping arm 6 and the second clamping arm 7 extends towards the sealing plate 3. This design allows the double-threaded bar 8 to rotate, causing the first clamping arm 6 and the second clamping arm 7 to move relatively closer or further apart in the sliding groove of the adjusting slide shell 5.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a second groove 12 is provided on one end face of the main cryogenic chamber 1, and a second sealing block 13 is fixed on the other end face. Similarly, a first groove 10 is provided on one end face of the auxiliary assembly chamber 2, and a first sealing block 11 is fixed on the other end face. The installation of these grooves and sealing blocks ensures the sealed connection between the chambers.

[0026] In addition, the upper end of the main low-temperature chamber 1 is equipped with a sealing cover 14, and a refrigeration unit 15 is installed on the inner bottom wall. The refrigeration unit 15 can accurately control the temperature inside the chamber to ensure that the low-temperature storage conditions are met.

[0027] The solution has the following working process: Before use, rotate the bidirectional threaded rod 8 from the adjustment knob 9. Since the surface of the bidirectional threaded rod 8 is symmetrically provided with bidirectional spiral patterns, and the first clamping arm 6 and the second clamping arm 7 are symmetrically arranged on the two spiral patterns of the bidirectional threaded rod 8, the bidirectional threaded rod 8 drives the first clamping arm 6 and the second clamping arm 7 to move closer or further away from each other. When the first clamping arm 6 and the second clamping arm 7 move closer together, they will clamp the sealing plates 3 at both ends of the main cryogenic chamber 1. The two sealing plates 3 seal the side ports of the main cryogenic chamber 1, so that the main cryogenic chamber 1 can be used independently.

[0028] When it is necessary to expand the cryogenic chamber storage space, the first clamping arm 6 and the second clamping arm 7 are moved away from each other. This allows the first clamping arm 6 and the second clamping arm 7 to unlock the sealing plates 3 at both ends of the main cryogenic chamber 1. Then, the auxiliary assembly chamber 2 is inserted into the gap between the two ends of the main cryogenic chamber 1 and the corresponding sealing plates 3. The first sealing block 11 of one auxiliary assembly chamber 2 is embedded in the second groove 12 of the main cryogenic chamber 1, while the first groove 10 of the other auxiliary assembly chamber 2 is fitted onto the second sealing block 13 of the main cryogenic chamber 1. Next, the sealing plate 3 seals one end of the corresponding auxiliary assembly chamber 2. Finally, the first clamping arm 6 and the second clamping arm 7 are adjusted... The clamping opening between the second clamping arms 7 extends until the sealing plates 3 at both ends of the first clamping arm 6 and the second clamping arm 7 are clamped together. In this way, the two auxiliary assembly chambers 2 can be sealed and combined to both ends of the main cryogenic chamber 1, which can realize the function of assembling and expanding the cryogenic chamber space. The total capacity of the cryogenic chamber can be flexibly adjusted according to the actual number of items: when more items are added and more storage space is needed, the capacity can be expanded by adding auxiliary assembly chambers 2. There is no need to purchase new cryogenic storage equipment. The expansion operation is simple. The installation and fixation of the auxiliary assembly chamber can be completed by controlling the opening and closing of the clamping arms through the adjustment knob 9. No complicated tools or professional skills are required.

[0029] During assembly, the first sealing block 11 and the second groove 12, and the first groove 10 and the second sealing block 13 cooperate to form a multi-layer sealing structure, which can effectively reduce heat exchange between the inside and outside of the cryogenic chamber and maintain the internal low-temperature environment. The design of the clamping arm clamping sealing plate 3 further enhances the overall sealing performance, ensuring the low-temperature storage effect whether the main cryogenic chamber is used independently or combined after expansion.

[0030] The core function of the refrigeration unit 15 is to reduce and maintain the temperature inside the main low-temperature chamber 1 through active refrigeration, so as to ensure that the space inside the chamber meets the requirements for low-temperature storage. The working principle of the refrigeration unit is based on the reverse Carnot cycle (an ideal refrigeration cycle model), which realizes the process of "transferring heat from low-temperature objects (inside the chamber) to high-temperature objects (outside the chamber)" by consuming energy (such as electrical energy).
