Description

Technical Field

[0001] This utility model belongs to the technical field of heat preservation devices, and more specifically, relates to a composite heat preservation box with high efficiency heat preservation. Background Technology

[0002] In logistics, industrial storage, and special environments (such as food drying and precision instrument storage), insulated boxes are critical equipment that must simultaneously meet requirements for airtightness, ventilation, and structural stability. Traditional insulated box designs often focus on optimizing a single function, such as improving insulation performance by adding insulation layers or using fixed shelves for categorized storage of goods. However, with the increasing complexity of application scenarios, users have significantly higher demands for equipment flexibility, safety, and maintenance efficiency, making it difficult for existing technologies to meet these multi-dimensional needs.

[0003] Existing product structural defects: Most insulated boxes use welded or bolted internal structures, and the position of the support plates is not adjustable. When storing items of different sizes, space needs to be adjusted by adding or removing partitions or fillers, which is cumbersome and can easily lead to disordered stacking of items due to improper space allocation.

[0004] Risks of misalignment and incorrect installation: The lack of a precise positioning mechanism makes it easy for items to tilt due to human error when the support plate is returned to its proper place. Some designs use scale markings to assist positioning, but this cannot eliminate operational errors, and the markings will wear down over time, further reducing accuracy.

[0005] Inadequate safety interlocking: Existing interlocking devices are mostly mechanical bolts or electromagnetic locks, which cannot effectively prevent the door from closing when the internal structure is not fully in place. This may cause the equipment to operate in a faulty state, leading to damage to items or safety hazards.

[0006] Dust prevention and ventilation are at odds: Ventilation design often neglects dust prevention requirements, allowing external particles to easily enter the enclosure and adhere to the product surface. Although some equipment is equipped with filters, insufficient airtightness allows dust to seep in through gaps in the enclosure door, resulting in high cleaning and maintenance costs.

[0007] Low maintenance efficiency: Many internal components use an integrated design; damage to a single part requires disassembling the entire housing structure, which is time-consuming and labor-intensive. If the locking mechanism malfunctions, specialized tools are needed for disassembly, further increasing downtime and maintenance costs.

[0008] To address the shortcomings of existing insulated boxes in terms of structural flexibility, positioning accuracy, safety interlocking, dustproof ventilation, and maintenance efficiency, an integrated solution is urgently needed. This solution should enable rapid placement and precise positioning of support plates through modular design, prevent misoperation through intelligent interlocking mechanisms, optimize ventilation and dustproof structures to improve product cleanliness, and reduce the total lifecycle maintenance cost. Utility Model Content

[0009] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite insulation box with high efficiency in heat preservation.

[0010] To achieve the aforementioned utility model objective, the technical solution adopted by this utility model includes a box body with an open side. A support mechanism is installed inside the box body. The support mechanism includes multiple horizontally arranged support plates that are slidably connected to the box body. The support plates can slide out of the box body in a horizontal direction. The multiple support plates are arranged in an array along the height direction of the box body. Vertical locking posts are arranged inside the box body corresponding to the positions of the multiple support plates. Vertical clearance grooves are opened in the box body corresponding to the positions of the locking posts. The clearance grooves are opened on the inner wall of the box body. The locking posts can slide in the clearance grooves in a direction that tends to approach or move away from the support plates. Semi-circular arc-shaped locking grooves are opened in the support plates corresponding to the positions of the locking posts. The locking posts can be locked in the locking grooves. Vertical locking grooves are opened in the box body corresponding to the positions of the clearance grooves. The groove opening direction of the locking groove is the same as the direction of the open side of the box body. A slidingly connected locking block is arranged in the locking groove. The end of the locking block near the clearance groove can be inserted into the clearance groove and can abut against the locking post.

[0011] Optionally, a locking ramp is provided at one end of the locking block near the clearance groove. The locking ramp is inclined from the side of the locking block away from the locking post to the side closer to the locking post, and the locking ramp abuts against the locking post.

[0012] Optionally, vertical spring blocks are fixed to both ends of the locking block, and a locking spring is fixed to the side of the spring block near the relief groove. One end of the locking spring is fixed to the spring block, and the other end of the locking spring is fixed to the inner wall of the locking groove. The axis of the locking spring is set horizontally.

[0013] Optionally, the enclosure is equipped with ventilation openings, and dustproof nets are installed inside the enclosure at the positions corresponding to the ventilation openings.

[0014] Optionally, the locking groove and the relief groove are perpendicular to each other.

[0015] Compared with the prior art, the advantages of this utility model include: (1) The present invention provides a high-efficiency thermal insulation composite insulation box. Through the cooperation of a vertically sliding locking post and a semi-circular locking groove on the support plate, the locking post automatically embeds into the locking groove when the support plate is in place, achieving dual positioning in both the horizontal and vertical directions, thus preventing product tilting due to placement deviation. When any support plate is not fully pushed in, the locking post cannot be locked into the corresponding locking groove. At this time, the locking bevel of the locking block moves outward under the push of the locking post, and its end protrudes from the inner wall of the box, forming a physical obstruction that prevents the box door from closing, forcibly interrupting the operation process and eliminating the risk of equipment malfunction from the source.

[0016] (2) This utility model provides a high-efficiency thermal insulation composite insulation box. The locking block is connected to a horizontally set locking spring through spring blocks at both ends to form an elastic locking mechanism. When all support plates are correctly installed, the locking spring pushes the locking block to keep it in a horizontal state, with its end flush with the inner wall of the box, ensuring smooth closure of the box door; if the support plate is not in place, the locking ramp converts the vertical displacement of the locking post into a horizontal thrust, triggering an outward movement warning of the locking block. This structure adopts a modular design, the support plates can be independently pulled out and replaced, and the locking assembly only needs to be disassembled to complete maintenance without damaging the overall structure of the box, significantly reducing downtime and maintenance costs.

[0026] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0027] Example 1 Please see Figures 1 to 3 A high-efficiency thermal insulation composite box includes a box body 1, with one side of the box body 1 open. A door 11 is hinged to the box body 1 at the open position, and the door 11 can seal the box body 1. A ventilation port 12 is provided on the box body 1, and a dustproof net 13 is provided inside the box body 1 at the position corresponding to the ventilation port 12 to prevent dust from entering the box body 1 through the ventilation port 12. A support mechanism is installed inside the box body 1.

[0028] Please see Figures 1 to 3 The support structure 2 includes multiple support plates 21, which are horizontally arranged and slidably connected to the box 1. The support plates 21 can slide out of the box 1 in the horizontal direction, and the multiple support plates 21 are arranged in an array along the height direction of the box 1.

[0029] Please see Figures 1 to 3 Inside the housing 1, there are locking posts 22 at positions corresponding to multiple support plates 21. The locking posts 22 are vertically arranged. The housing 1 has a clearance groove 24 at the position of the locking post 22. The clearance groove 24 is vertically arranged and is opened on the inner wall of the housing 1. The locking post 22 can slide within the clearance groove 24. The sliding direction of the locking post 22 is to slide towards the support plate 21 or away from the support plate 21. The support plate 21 has a locking groove 23 at the position of the locking post 22. The locking groove 23 is semi-circular. The locking post 22 can be locked in the locking groove 23.

[0030] Please see Figures 1 to 3A locking groove 31 is provided inside the housing 1 at the position corresponding to the clearance groove 24. The locking groove 31 is vertically arranged, and the opening direction of the locking groove 31 is the same as the opening direction of the fire box 1. The locking groove 31 and the clearance groove 24 are perpendicular to each other. A locking block 32 is provided in the locking groove 31. The locking block 32 is slidably connected in the locking groove 31. The end of the locking block 32 near the clearance groove 24 can be inserted into the clearance groove 24. The end of the locking block 32 near the clearance groove 24 can abut against the locking post 22. A locking inclined surface 321 is provided at the end of the locking block 32 near the clearance groove 24. The locking inclined surface 321 is inclined from the side of the locking block 32 away from the locking post 22 towards the side closer to the locking post 22. The locking inclined surface 321 abuts against the locking post 22. 1~ Please see Figures 1 to 3 Spring blocks 41 are fixedly connected to both ends of the locking block 32. Each spring block 41 is vertically arranged. A locking spring 42 is fixedly connected to the side of the spring block 41 near the relief groove 24. One end of the locking spring 42 is fixedly connected to the spring block 41, and the other end of the locking spring 42 is fixedly connected to the inner wall of the locking groove 31. The axis of the locking spring 42 is horizontally arranged. When the locking pin 22 is engaged in the locking groove 23, the locking block 32 is inserted into the locking groove 31. One end of the locking block 21 abuts against the locking post 22, and the end of the locking block 32 away from the locking post 22 is on the same plane as the box body 1, so that the box door 11 can be closed normally.

At the same time, the vertical elastic structure of the locking post 22 can accommodate slight operational errors, ensuring that the support plate 21 is in the correct position every time it is closed.

[0033] Intelligent interlocking protection: When all support plates 21 are correctly installed, the locking block 32 remains horizontal under the action of the spring, flush with the inner wall of the housing 1, and the housing door 11 can be closed normally. If any support plate 21 is not in place, the locking post 22 will push the inclined structure of the locking block 32, causing its end to protrude out of the housing 1, forming a physical barrier to prevent the housing door 11 from closing accidentally, effectively avoiding the equipment from operating with a fault.

[0034] Dustproof ventilation optimization: The dustproof nets 13 installed at the ventilation openings 12 can intercept external particles. Combined with the airtight door 11 structure, it can prevent dust from adhering to the product surface while ensuring air circulation, thereby improving product cleanliness and reducing subsequent cleaning processes.

[0035] Modular design for easy maintenance: The support mechanism adopts an independent sliding design, and a single support plate 21 can be removed and replaced individually when damaged, without disassembling the entire housing 1 structure. The locking assembly is connected to the housing via spring block 41. If maintenance is required after long-term use, only the locking spring 42 needs to be removed to complete the maintenance, reducing the total life cycle cost of the equipment.
