Description

Technical Field

[0001] This utility model relates to the field of box wall panel technology, and in particular to a box wall panel structure that effectively prevents cold bridging. Background Technology

[0002] China is the world's largest consumer of pork, with fresh pork accounting for over 70%. As residents demand higher quality meat, the problems of microbial growth and meat deterioration caused by traditional ambient temperature transportation urgently need to be addressed. Refrigerated trucks have become the core carrier for the cross-provincial and cross-regional circulation of fresh pork.

[0003] After slaughter, pork (half a carcass) is suspended from the top rails of a refrigerated truck using metal hooks for transport in a three-dimensional suspended state. This avoids the airflow obstruction caused by the compression of meat pieces during traditional stacking transport, which can lead to spoilage of some pork. However, during transport, if the road surface is uneven, the bumps of the refrigerated truck will cause the pork suspended inside the refrigerated compartment to swing. As the amplitude of the swing gradually increases, the pork may hit the wall panels of the refrigerated compartment. Due to the large weight of the pork, the impact with the wall panels can cause the insulation layer inside the wall panels to break. This causes the insulation layer to lose its heat insulation capacity at the break point, creating a heat conduction path and thus a cold bridge. This leads to localized excessive temperature in the pork inside the refrigerated compartment. Excessive temperature accelerates the reproduction of microorganisms, affecting the quality of the transported pork and reducing its freshness. Utility Model Content

[0004] In view of the above-mentioned problems with the box wall panel structure for effectively preventing cold bridges, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a box wall panel structure for efficient prevention of cold bridge, including a refrigerated box, with wall panels symmetrically arranged on both sides of the refrigerated box, each wall panel including a decorative panel, a filling groove on the decorative panel, an insulation board inside the decorative panel, and an inner soft board on the decorative panel.

[0006] The insulation board and the inner soft board are both placed in the filling groove, and a hollow layer is provided between the insulation board and the inner soft board, and the hollow layer is filled with argon gas.

[0007] The decorative panel has a mounting groove on the side away from the filling groove, and a display unit is provided in the mounting groove. The display unit includes a protective cover and a negative pressure unit is connected to the protective cover.

[0008] As a preferred embodiment of the efficient anti-cold bridging box wall panel structure of this utility model, the display unit includes a mounting frame, on which conductive sheets are symmetrically arranged, and a tungsten wire is arranged between two of the conductive sheets.

[0009] As a preferred embodiment of the box wall panel structure for efficient prevention of cold bridging described in this utility model, the protective cover is disposed in the mounting groove and is made of acrylic material.

[0010] As a preferred embodiment of the box wall panel structure for efficient prevention of cold bridge described in this utility model, the negative pressure unit includes a connecting pipe, which is disposed on a protective cover. A piston cylinder is disposed at the end of the connecting pipe away from the protective cover, and a piston rod is slidably disposed inside the piston cylinder.

[0011] As a preferred embodiment of the box wall panel structure for efficient prevention of cold bridge described in this utility model, the decorative panel is provided with a slide and a fixed seat, a rack is slidably provided on the slide, and a rack is fixedly provided on the fixed seat.

[0012] As a preferred embodiment of the efficient anti-cold bridge box wall panel structure of this utility model, the negative pressure unit further includes a rotating seat, on which a turntable is rotatably mounted, and a connecting rod is fixedly connected to the turntable. A pull rod is rotatably connected to the end of the connecting rod away from the turntable, and a gear is rotatably connected to the end of the pull rod away from the connecting rod. The gear meshes with rack one and rack two respectively.

[0013] The beneficial effects of this utility model are:

[0014] 1. By installing insulation boards inside the wall panels, the interior of the refrigerator can be insulated. At the same time, a hollow layer is set between the inner soft board and the insulation board. When pork hits the inner soft board, the inner soft board will deform appropriately, and the argon gas in the hollow layer will be compressed, thus absorbing the impact force of the pork hitting the inner soft board. In addition, argon gas has a lower thermal conductivity coefficient than air, which further improves the insulation effect of the box wall panels. This avoids the heat conduction path at the fracture point of the insulation layer after it breaks, thus preventing the formation of cold bridges. This improves the refrigeration effect of transported pork and ensures the freshness of the pork.

[0015] 2. By setting up a negative pressure unit and a display unit, when the insulation board breaks, the argon gas in the hollow layer will flow to the display unit, causing the energized tungsten wire to come into contact with the argon gas. At this time, a blue-white light source will appear at the tungsten wire, thereby determining whether the insulation layer has broken. This avoids the situation where the insulation layer inside the refrigerated truck wall panel is damaged before the pork is transported, which would lead to a decrease in the freshness of the transported pork.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-2This is the first embodiment of the present invention, providing a highly efficient cold-bridge prevention box wall panel structure. This highly efficient cold-bridge prevention box wall panel 11 structure includes a refrigerated box 1, with wall panels 11 symmetrically arranged on both sides of the refrigerated box 1. Multiple metal hooks are provided on the top of the refrigerated box 1. The refrigerated box 1 is mounted on a refrigerated truck. The wall panels 11 include decorative panels 12, with filling grooves on the decorative panels 12. An insulation board 13 is disposed within the decorative panels 12. The insulation board 13 is preferably made of extruded polystyrene foam, which is a polymer foam material prepared by extrusion molding. The internal pores are closed-cell honeycomb-shaped, with extremely low thermal conductivity, which can effectively block heat transfer. However, it is a brittle material. The decorative panel 12 is provided with an inner soft board 14. When the inner soft board 14 is subjected to external force, it can undergo appropriate deformation. The filling groove is opened on the side of the two wall panels 11 that are close to each other. The insulation board 13 is set at the bottom of the filling groove, and a sealing strip is provided at the connection between the edge of the insulation board 13 and the wall of the filling groove. There is an appropriate gap between the insulation board 13 and the bottom surface of the filling groove. The inner soft board 14 is set at the opening of the filling groove, and the inner soft board 14 is sealed to the decorative panel 12.

[0028] The insulation board 13 and the inner soft board 14 are both placed in the filling groove. A hollow layer 15 is provided between the insulation board 13 and the inner soft board 14. The hollow layer 15 is filled with argon gas. Argon gas is colorless, odorless, and non-flammable. Moreover, the thermal conductivity of argon gas is lower than that of air. By filling the wall panel 11 with argon gas, the heat insulation performance of the wall panel 11 can be further improved, thereby reducing the risk of cold bridging on the wall panel 11.

[0029] The decorative panel 12 has a mounting groove 121 on the side away from the filling groove. The mounting groove 121 is connected to the filling groove. A display unit 2 is provided at the mounting groove 121. The display unit 2 includes a protective cover 21 and a negative pressure unit 3 is connected to the protective cover 21.

[0030] During use, when the refrigerated truck travels to a bumpy road, the refrigerated truck will shake. Since the pork inside the refrigerated compartment 1 is suspended and has a certain mass, the pork will swing inside the refrigerated compartment 1. As the refrigerated truck continues to shake, the swing amplitude of the pork inside the refrigerated compartment 1 increases, and then the pork begins to contact and hit the wall panel 11 on the refrigerated compartment 1.

[0031] When the pork comes into contact with and impacts the inner soft plate 14, the inner soft plate 14 will deform to a certain extent. The deformation of the inner soft plate 14 will absorb the impact force from the pork. At the same time, during the deformation of the inner soft plate 14, the argon gas filled in the hollow layer 15 will be compressed due to the deformation of the inner soft plate 14, which will further absorb the impact force from the pork, thereby avoiding damage to the insulation plate 13 caused by the impact of the pork.

[0032] Example 2

[0033] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0034] The display unit 2 includes a mounting bracket 22, on which conductive sheets 23 are symmetrically arranged. A tungsten wire 24 is arranged between two conductive sheets 23. The mounting bracket 22 is located in the mounting groove 121 and is connected to the decorative panel 12. The two ends of the tungsten wire 24 are respectively connected to one end of the conductive sheet 23. The tungsten wire 24 is electrically connected to the conductive sheet 23. A power supply is also provided on the decorative panel 12. A second protective cover is provided on the decorative panel 12. The power supply is located inside the second protective cover and is electrically connected to the two conductive sheets 23.

[0035] The protective cover 21 is installed in the mounting groove 121. The protective cover 21 is made of acrylic material. The protective cover 21 is connected to the decorative panel 12. The protective cover 21, the decorative panel 12, and the insulation board 13 form a protective cavity. The mounting bracket 22, the conductive sheet 23, and the tungsten wire 24 are all installed in the protective cover 21.

[0036] The negative pressure unit 3 includes a connecting pipe 31, which is mounted on the protective cover 21. A piston cylinder 32 is mounted on the end of the connecting pipe 31 away from the protective cover 21. A piston rod 33 is slidably mounted inside the piston cylinder 32. The connection between the connecting pipe 31 and the protective cover 21 is sealed with a sealing strip. A one-way valve is mounted on the end of the connecting pipe 31 that is connected to the protective cover 21. The one-way valve prevents the gas in the connecting pipe 31 from entering the protective cover 21, but the gas inside the protective cover 21 can enter the connecting pipe 31 through the one-way valve.

[0037] A one-way valve is installed in the middle of the connecting pipe 31. The one-way valve prevents external gas from entering the connecting pipe 31. The connecting pipe 31 is interconnected with the piston cylinder 32.

[0038] The decorative panel 12 is provided with a slide 34 and a fixed seat 35. A rack 341 is slidably mounted on the slide 34, and a rack 351 is fixedly mounted on the fixed seat 35. A groove is provided at the end of the slide 34 away from the decorative panel 12. A sliding shaft is symmetrically arranged on one side of the rack 341 and is slidably mounted in the groove. One end of the rack 341 is connected to the piston rod 33. An appropriate distance is provided between the rack 341 and the rack 351.

[0039] The negative pressure unit 3 also includes a rotating seat 36, on which a turntable 37 is rotatably mounted. A connecting rod 38 is fixedly connected to the turntable 37. A pull rod 39 is rotatably connected to the end of the connecting rod 38 away from the turntable 37. A gear 391 is rotatably connected to the end of the pull rod 39 away from the connecting rod 38. The gear 391 meshes with rack 1 341 and rack 2 351 respectively. The gear 391 is located between rack 1 341 and rack 2 351.

[0040] During use, before transporting pork in a refrigerated truck, the power is turned on to energize the tungsten wire 24 and rotate the turntable 37. At this time, the turntable 37 will drive the connecting rod 38 to rotate synchronously. Then, during the rotation of the connecting rod 38, it will pull the pull rod 39. Then, the pull rod 39 will pull the gear 391. The gear 391 will be displaced under the action of the pull rod 39. During the displacement, the gear 391 will start to rotate under the action of the rack 351. The rotation of the gear 391 will drive the rack 341, causing the rack 341 to start to move along the slide groove. Then, the rack 341 will drive the piston rod 33.

[0041] By continuously rotating the grinding disc, the piston rod 33 reciprocates along the piston cylinder 32, causing the gas in the protective chamber to be discharged through one-way valve one and one-way valve two. At this time, the protective chamber is in a relative vacuum state.

[0042] When the insulation board 13 breaks and cracks appear, the argon gas in the hollow layer 15 will flow into the protective cavity under the action of negative pressure. At this time, the argon gas will come into contact with the tungsten wire 24 that is powered by electricity. Then, a blue-white light source will be displayed in the area of ​​the tungsten wire 24. The color of the light source displayed at the tungsten wire 24 can be used to determine whether the insulation board 13 is damaged.

[0043] The remaining structure is the same as that in Example 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
