Description

Technical Field

[0001] This utility model relates to the field of thermal insulation sealing components, specifically to a high-efficiency, high-thermal-insulation sealing component for the air duct of a cold chain vehicle. Background Technology

[0002] In the modern cold chain logistics field, dual-temperature refrigerated trucks, with their unique design—a refrigerated zone (maintained at 0 to 8 degrees Celsius) and a frozen zone (constantly at -18 degrees Celsius)—have become key to ensuring the safe transportation of goods with different temperature requirements. However, due to the significant temperature difference between the two zones, and the fact that they are separated only by a special heat insulation panel, coupled with the U-shaped air duct at the bottom of the vehicle to promote the circulation of cold air, an unintended phenomenon occurs: extremely low-temperature air in the frozen zone permeates into the refrigerated zone through the air duct, which may cause damage to the items in the latter due to overcooling.

[0003] In existing technologies, the insulation board area is often installed first, and then waste stretch film or cloth strips are used to plug the air guide channels at the bottom of the insulation board one by one. This is inefficient, cannot achieve integrated installation, and results in a long installation time.

[0004] Therefore, this utility model provides a high-efficiency, high-insulation and heat-resistant sealing component for the air guide channel of cold chain vehicles to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a high-efficiency, high-insulation and heat-insulating sealing component for the air guide channel of cold chain vehicles, so as to solve the problems of quick installation and integrated installation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency, high-insulation, and heat-resistant sealing component for refrigerated truck air ducts includes a surface panel made of PP material with a high-insulation interior and a temperature-reflective inner layer. The bottom of the surface panel is connected to multiple sealing components via a first position adjustment component. The first position adjustment component is made of a soft fabric material. Each sealing component includes a sealing sleeve and a sealing box. The sealing sleeve is made of a soft inner insulation material and a reflective surface material. The sealing box contains a transmission component and a sealing assembly. This device, with its surface panel and sealing components, allows for convenient, integrated installation that is robust and wear-resistant. The first position adjustment component allows for independent position adjustment. The sealing components ensure a good seal, are reusable, and have a long service life. The number of components can be selected based on the number of air ducts in the truck compartment. It is simple and convenient to use, low-cost, and space-saving. The multiple sealing components allow for easy replacement; damaged parts can be replaced or repaired at low cost.

[0008] Preferably, the surface layer is integrally formed.

[0009] Preferably, there are multiple surface panels, which are connected by a second position adjusting member, and the second position adjusting member is made of the same material as the first position adjusting member.

[0010] Preferably, the sealing assembly includes an adjusting plate, which is slidably connected to the side wall of the sealing box. One end face of the adjusting plate is connected to one end face of the sealing plate, and the sealing plate is fixedly installed at one end of the sealing box. The transmission assembly includes a push rod, which is slidably connected inside the sealing box. A top extension inclined ring is fixedly installed on the outer wall of the middle part of the push rod, and the diameter of the top extension inclined ring increases sequentially from the inside to the outside. A stop block is fixedly installed on the inner side wall of the adjusting plate, and one end of the stop block is set as an arc surface. The top extension inclined ring and the stop block are connected to each other. The device is matched with a spring fixedly installed on the outer wall of the abutting block, and the other end of the spring is fixedly connected to the inner wall of the adjusting plate. In the initial state, the abutting block of the device abuts against the smaller diameter end of the top extension inclined ring. When installation is required, the sliding push rod is used to move the adjusting plate outward, thereby enabling the device to be used in various sizes of air guide slots. This allows the adjusting plate to expand the sealing sleeve and simultaneously achieves a snap-fit ​​fixation between the adjusting plate and the air guide slot, preventing the device from falling off when the vehicle is in motion or when subjected to vibration.

[0011] Preferably, a retaining ring is fixedly installed on the outer wall of one end of the push rod, and the number of retaining rings is multiple and evenly spaced; a limiting plate is slidably connected to the inner bottom wall of the sealed box, one end of the top of the limiting plate is set as an inclined surface, a limiting spring is fixedly installed at the bottom of the limiting plate, and the other end of the limiting spring is fixedly connected to the inner wall of the bottom of the sealed box; when the push rod is slid, in order to increase the stability of the clamping and fixing and to prevent the adjusting plate from falling off, the retaining ring will engage with the limiting plate when the push rod is slid, and the limiting plate restricts the reset of the push rod, so that the device can be used for air guide channels of different widths and sizes.

[0012] Preferably, an extrusion plate is fixedly installed on the outer wall of the push rod, and a sliding plate is slidably connected inside the extrusion plate. One end of the sliding plate is fixedly connected to the inner side wall of the adjustment plate. An upper top plate is slidably connected inside the sliding plate, and an upper top spring is fixedly installed at the bottom of the upper top plate. The bottom of the upper top spring is fixedly connected to the inner bottom wall of the sliding plate. The sliding plate, the extrusion plate, the adjustment plate, and the sealing plate form a sealing cavity, and the interior of the sealing cavity is filled with sealing material. The sealing material of this device is preferably heat-insulating cotton.

[0013] Preferably, a sealing block is slidably connected inside the sealing plate, and the sealing block is fixedly connected to the inner wall of the adjusting plate. One end of the sealing block abuts against a counterweight ring, and the counterweight ring is fixedly installed on the outer wall of one end of the push rod. A compression plate is fixedly installed at one end of the push rod. A main air bladder is provided inside the sealing plate, and the main air bladder is filled with nitrogen gas. The main air bladder matches the compression plate. A sealing air bladder is provided inside the sealing block, and the sealing air bladder is conductively connected to the main air bladder. The sealing air bladder of this device can automatically... The device automatically seals gaps to achieve a comprehensive sealing effect. When the sliding push rod is moved, the sliding plate expands outward, and the sealing block moves accordingly. At the same time, the space inside the sealing cavity will increase, which may cause incomplete sealing. The extrusion plate of the device will compress the sealing material to achieve a complete seal. At the same time, there will be gaps between the sliding plate and the upper part of the sealing block, which are sealed by the top plate and the sealing airbag. The airbag of the device is filled with nitrogen, which can achieve a heat insulation effect, ensure the sealing effect, and prevent the phenomenon of cold air mixing.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This device, through the design of the surface plate and sealing components, enables convenient and integrated installation, while also being robust and wear-resistant. The first position adjustment component allows for independent position adjustment. The sealing components ensure a good seal, are reusable, and have a long service life. The number of components can be selected based on the number of air ducts in the vehicle compartment. It is simple and convenient to use, low-cost, and space-saving. Multiple sealing components are available, allowing for easy replacement. Damaged components can be replaced and repaired at a low cost.

[0016] 2. In its initial state, the abutting block of this device abuts against the smaller diameter end of the top extension inclined ring. When installation is required, the sliding push rod is used to move the adjusting plate outward. This allows it to be used in various sizes of air guide channels, expanding the sealing sleeve of the adjusting plate and locking the adjusting plate with the air guide channel to prevent the device from falling off when the vehicle is in motion or when it is subjected to vibration.

[0017] 3. In order to increase the stability of clamping and fixing when the sliding push rod is in use, and to prevent the adjustment plate from falling off, the retaining ring will engage with the limiting plate when the push rod is in motion. The limiting plate restricts the push rod from resetting, so that this device can be used for air guide channels of different widths and sizes.

[0018] 4. The sealing airbag of this device can automatically seal gaps to achieve a comprehensive sealing effect. When the sliding push rod is moved, the sliding plate moves with the adjusting plate as the adjusting plate expands outward. At the same time, the sealing block also moves with the adjusting plate. At this time, the space inside the sealing cavity will increase, which may cause incomplete sealing. The extrusion plate of this device will compress the sealing material to achieve a complete seal. At the same time, there will be gaps between the sliding plate and the upper part of the sealing block, which are sealed by the top plate and the sealing airbag. The airbag of this device is filled with nitrogen, which can achieve a heat insulation effect, ensure the sealing effect, and prevent the phenomenon of cold air mixing. Attached Figure Description

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] A high-efficiency, high-insulation, and heat-resistant sealing component for refrigerated truck air ducts, as shown in the attached document. Figure 1-4 As shown, it includes a surface panel 1, which is made of PP material, with a high-insulation material inside and a temperature-reflective layer sewn on the inner layer. The bottom of the surface panel 1 is connected to a sealing assembly 2 via a first position adjusting member 3. There are multiple sealing assemblies 2. The first position adjusting member 3 is made of soft fabric material. (See attached diagram.) Figure 5-6As shown, the sealing component 2 includes a sealing sleeve 4 and a sealing box 5. The sealing sleeve 4 is made of soft inner insulation material and reflective surface material. The sealing box 5 contains a transmission component and a sealing component. This device, through the setting of the surface plate 1 and the sealing component 2, makes the device easy to install, integrated, and sturdy and wear-resistant. The position can be adjusted independently through the setting of the first position adjustment component 3. The sealing component 2 of this device can ensure the sealing effect, can be recycled, has a long service life, and can be used in any number according to the number of air ducts in the carriage. It is simple and convenient to use, low cost, and does not take up space. There are multiple sealing components 2 in this device, which can be replaced independently. Different damaged parts can be replaced and repaired at low cost.

[0032] As attached Figure 1-2 As shown, the surface panel 1 is integrally formed;

[0033] Example 1: The surface plate 1 of this device is integrally formed and can cover 9.6-15.5 meters. It is made according to the width of the refrigerated trucks of all manufacturers on the market. This method of installation is faster and more convenient. When in use, the device is directly fastened into the corresponding air guide channel. The surface plate 1 plays the role of stabilizing and connecting the sealing components.

[0034] As attached Figure 3-4 As shown, there are multiple surface panels 1, which are connected by a second position adjusting member 6. The second position adjusting member 6 is made of the same material as the first position adjusting member 3.

[0035] Example 2: There are multiple surface panels 1. Through the multi-piece adjustable width style, it can be adjusted independently according to the number of different carriages and air ducts. This method is not only easy to install, but also applicable to the use of various vehicle models, and easy to adjust.

[0036] As attached Figure 5-6 As shown, the sealing assembly includes an adjusting plate 7, which is slidably connected to the side wall of the sealing box 5.

[0038] A stop block 11 is fixedly installed on the inner wall of the adjusting plate 7. One end of the stop block 11 is set as an arc surface. The top extension inclined ring 10 matches the stop block 11. A stop spring 18 is fixedly installed on the outer wall of the stop block 11. The other end of the stop spring 18 is fixedly connected to the inner wall of the adjusting plate 7. In the initial state, the stop block 11 of this device abuts against the smaller diameter end of the top extension inclined ring 10. When installation is required, the sliding push rod 9 is used to drive the adjusting plate 7 to move outward. This can achieve the effect of expanding the sealing sleeve 4 of the adjusting plate 7 and fixing the adjusting plate 7 to the air guide channel, so as to prevent the device from falling off when the vehicle is moving or when it is subjected to vibration.

[0039] As attached Figure 6-7 As shown, a retaining ring 12 is fixedly installed on the outer wall of one end of the push rod 9. There are multiple retaining rings 12, which are evenly spaced.

[0040] A limiting plate 13 is slidably connected to the inner bottom wall of the sealing box 5. One end of the top of the limiting plate 13 is set as an inclined surface, and a limiting spring 14 is fixedly installed at the bottom of the limiting plate 13. The other end of the limiting spring 14 is fixedly connected to the inner wall of the bottom of the sealing box 5. When the sliding push rod 9 is slidable, in order to increase the stability of the clamping and fixation and to prevent the adjusting plate 7 from falling off, the retaining ring 12 will engage with the limiting plate 13 when the sliding push rod 9 is slidable. The limiting plate 13 restricts the reset of the push rod 9, so that the device can be used for air guide channels of different widths and sizes.

[0041] As attached Figure 6 and attached Figure 8 As shown, a pressing plate 15 is fixedly installed on the outer wall of the push rod 9. A sliding plate 16 is slidably connected inside the pressing plate 15. One end of the sliding plate 16 is fixedly connected to the inner side wall of the adjusting plate 7. An upper top plate 19 is slidably connected inside the sliding plate 16. An upper top spring 17 is fixedly installed at the bottom of the upper top plate 19. The bottom of the upper top spring 17 is fixedly connected to the inner bottom wall of the sliding plate 16. The sliding plate 16, the pressing plate 15, the adjusting plate 7, and the sealing plate 8 form a sealing cavity. The interior of the sealing cavity is filled with sealing material. The sealing material of this device is preferably heat insulation cotton.

[0042] As attached Figure 9-10 As shown, a sealing block 20 is slidably connected inside the sealing plate 8. The sealing block 20 is fixedly connected to the inner wall of the adjusting plate 7. One end of the sealing block 20 abuts against the abutting inclined ring 21. The abutting inclined ring 21 is fixedly installed on the outer wall of one end of the push rod 9.

[0043] One end of the push rod 9 is fixedly installed with an extrusion plate 22. The sealing plate 8 has a main air bladder 23 inside, which is filled with nitrogen. The main air bladder 23 matches the extrusion plate 22. The sealing block 20 has a sealing air bladder 24 inside, which is connected to the main air bladder 23. The sealing air bladder 24 of this device can automatically seal the gaps to achieve an all-round sealing effect. When the push rod 9 is slid, the sliding plate 16 moves with the adjusting plate 7 as it expands outward. At the same time, the sealing block 20 moves with the adjusting plate 7. At this time, the space inside the sealing cavity will increase, which may cause incomplete sealing. The extrusion plate 15 of this device will squeeze the sealing material to achieve a full seal. At the same time, there will be a gap between the sliding plate 16 and the upper part of the sealing block 20, which is sealed by the top plate 19 and the sealing air bladder 24. The air bladder of this device is filled with nitrogen, which can achieve a heat insulation effect, ensure the sealing effect, and prevent the phenomenon of cold air mixing.
