Description

Technical Field

[0001] This utility model belongs to the field of refrigeration and insulation technology, and in particular relates to a sealing structure for the rear door of a refrigerated truck. Background Technology

[0002] The refrigerated truck rear door sealing structure refers to the design and construction used to seal the rear door of a refrigerated truck. Its main function is to maintain the temperature inside the truck compartment, prevent cold air from leaking out, and avoid the influence of external temperature on the interior of the truck compartment. Generally speaking, the refrigerated truck rear door sealing structure includes components such as sealing strips, door frame, door panel, and door lock to ensure the insulation effect and energy efficiency of the refrigerated truck.

[0003] When the rear door of a refrigerated truck is closed, gaps often appear at the connection between the truck bed and the rear door. Outside temperature can enter the truck bed through these gaps, and cold air can also leak out from the gaps, resulting in unstable temperature inside the truck bed and affecting the freshness and quality of the goods. Therefore, we have proposed a sealing structure for the rear door of a refrigerated truck. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing structure for the rear door of a refrigerated truck. The spring rebound causes the slider to move the slide bar, and then the slide bar will drive the sealing plate to slide on the turntable, thus solving the problem of sealing the gaps when the turntable is closed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sealing structure for the rear door of a refrigerated truck, including a truck compartment, a refrigerated compartment fixedly connected to the inner wall of the truck compartment, a sealing mechanism on the refrigerated compartment, and a locking mechanism on the refrigerated compartment.

[0007] The sealing mechanism includes a connecting block, which has a groove inside. A slider is slidably connected to the inner wall of the groove. A fixing rod is fixedly connected to the outer surface of the slider. A limit block is fixedly connected to the end of the fixing rod away from the slider. A spring is fixedly connected to the side of the slider close to the limit block. A slide bar is fixedly connected to the bottom of the slider. A sealing plate is fixedly connected to the outer surface of the slide bar. A revolving door is rotatably connected to the inner wall of the carriage. A handle is fixedly connected to the outer surface of the revolving door.

[0008] Furthermore, a total of four connecting blocks are provided. The bottom of the first connecting block is fixedly connected to the top of the refrigerator compartment. The internal components of the first connecting block are identical. The outer surface of the fixing rod is slidably connected to the inner wall of the first connecting block. The end of the spring away from the slider is fixedly connected to the inner wall of the slide groove.

[0009] Furthermore, the inner side of the spring is sleeved with the outer surface of the fixing rod, the outer surface of the slide bar is slidably connected to the top of the refrigerator compartment, and there are two rotating doors, the outer surface of the rotating door is slidably connected to the outer surface of the sealing plate.

[0010] Furthermore, the locking mechanism includes a locking block one fixedly connected to the outer surface of the handle, a locking block two fixedly connected to the outer surface of the handle, and a limit strip fixedly connected to the side of the locking block two near the locking block one.

[0011] Furthermore, there are two limiting strips. The outer surface of the limiting strip is slidably connected to the outer surface of the locking block. The inner wall of the locking block is threaded with a bolt. The outer surface of the bolt is threaded to the inner wall of the limiting strip. The bottom of the locking block is fixedly connected with a limiting cylinder. The top of the limiting cylinder is in contact with the bottom of the bolt.

[0012] Furthermore, a frame is fixedly connected to the outer surface of the revolving door, a retaining strip is slidably connected to the outer surface of the frame, the outer surface of the retaining strip is fixedly connected to the outer surface of the revolving door, and a second connecting block is fixedly connected to the outer surface of the frame; there are two second connecting blocks in total.

[0013] Furthermore, a convex block is slidably connected to the inner wall of the connecting block two, an insert block is inserted into the inner wall of the convex block, a moving rod is fixedly connected to the side of the insert block away from the convex block, an extension block is slidably connected to the outer surface of the moving rod, and the outer surface of the extension block is fixedly connected to the outer surface of the refrigerated compartment.

[0014] Furthermore, a second spring is fixedly connected to one side of the extension blocks that are close to each other, and the end of the second spring away from the extension block is fixedly connected to the outer surface of the insertion block. The inner side of the second spring is sleeved with the outer surface of the moving rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a sealing plate. When the revolving door is opened, it pushes the sealing plate, causing the sealing plate to slide on the refrigerated compartment. Simultaneously, the sliding plate moves the slider within the groove, which in turn pushes the fixing rod. The sealing plate, which slides on the revolving door, effectively seals the gap between the revolving door and the refrigerated compartment, preventing external temperature from entering and reducing temperature fluctuations within the compartment. This ensures that cold air does not leak from the compartment, thus extending the freshness and quality of the goods.

[0017] 2. This utility model incorporates an insert block. The locking strip drives the convex block to slide into the connecting block two on the frame. At this time, the convex block pushes the insert block, causing it to move upward. Then, the insert block drives the moving rod to slide within the extension block, while simultaneously squeezing the spring two. By using the insert block, which can be locked within the convex block, the rotating door is positioned and then locked. This ensures more precise contact between the refrigerator compartment and the rotating door, avoiding poor sealing caused by installation errors or improper operation, and reducing operational errors or incomplete sealing due to inaccurate installation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The sealing mechanism 2 includes a connecting block 201, which has a groove 202 inside. A slider 203 is slidably connected to the inner wall of the groove 202. A fixing rod 204 is fixedly connected to the outer surface of the slider 203. The groove 202 restricts the movement trajectory of the slider 203, so that the slider 203 can only move along a preset track, ensuring that the sealing mechanism 2 can work normally and stably. A limit block 206 is fixedly connected to the end of the fixing rod 204 away from the slider 203, and a limit block 206 is fixed to the side of the slider 203 closest to the limit block 206. A spring 205 is fixedly connected to the bottom of the slider 203, and a slide bar 207 is fixedly connected to the bottom of the slide bar 207. A sealing plate 208 is fixedly connected to the outer surface of the slide bar 207. When the slide bar 207 resets, it will drive the sealing plate 208 to move, so that the sealing plate 208 resets. Then the sealing plate 208 can block and seal the gaps to prevent cold air leakage from the refrigerated compartment 102. A revolving door 209 is rotatably connected to the inner wall of the compartment 101. A handle 210 is fixedly connected to the outer surface of the revolving door 209. There are four connecting blocks 201 in total. The bottom of the connecting block 201... The part is fixedly connected to the top of the refrigerated compartment 102. The rotating door 209 can be opened or closed by the handle 210. When the rotating door 209 moves, it will cause the sealing mechanism 2 to move automatically, so that the sealing mechanism 2 can automatically function. The connecting block 201 contains the same parts. The outer surface of the fixing rod 204 is slidably connected to the inner wall of the connecting block 201. The end of the spring 205 away from the slider 203 is fixedly connected to the inner wall of the slide groove 202. The inner side of the spring 205 is sleeved with the outer surface of the fixing rod 204. The fixing rod 204 is...

The outer surface of the slide bar 207 is slidably connected to the top of the refrigerator compartment 102. There are two rotating doors 209. The outer surface of the rotating door 209 is slidably connected to the outer surface of the sealing plate 208. The slide bar 207 is sandwiched between the connecting block 201 and the refrigerator compartment 102. At this time, the position of the slide bar 207 is restricted to prevent it from disengaging from the sealing mechanism 2, ensuring that the sealing mechanism 2 can seal stably.

[0030] The locking mechanism 3 includes a locking block 301 fixedly connected to the outer surface of the handle 210, and a locking block 302 fixedly connected to the outer surface of the handle 210. A limiting strip 303 is fixedly connected to the side of the locking block 302 closest to the locking block 301. Two limiting strips 303 are provided. When the locking block 302 moves, it drives the limiting strips 303 to move, causing the limiting strips 303 to enter the locking block 301, thereby further locking the revolving door 209. The outer surface of the limiting strip 303 is slidably connected to the outer surface of the locking block 301. A bolt 304 is threadedly connected to the inner wall of the locking block 301, and the outer surface of the bolt 304 is threadedly connected to the inner wall of the limiting strip 303. A limiting sleeve 305 is fixedly connected to the bottom of the locking block 301, allowing the bolt 304 to be tightened within the limiting strip 303 and the locking block 301. At this time, the locking blocks 301 and 302 are locked. The two revolving doors 209 are fixed in position to prevent them from opening during vehicle operation. The top of the limiting cylinder 305 contacts the bottom of the bolt 304. A frame 306 is fixedly connected to the outer surface of the revolving door 209, and a retaining strip 307 is slidably connected to the outer surface of the frame 306. When the revolving door 209 moves, it also moves the frame 306 and the retaining strip 307. At this time, the frame 306 and the retaining strip 307 initially position the revolving door 209 to facilitate subsequent locking. The outer surface of the retaining strip 307 is fixedly connected to the outer surface of the revolving door 209. A second connecting block 308 is fixedly connected to the outer surface of the frame 306. There are two connecting blocks 308. When the frame 306 moves, it moves the second connecting block 308, which facilitates the next step of the locking mechanism 3 to drive the revolving door 209 and initially fix its position.

[0031] A convex block 309 is slidably connected to the inner wall of connecting block 308. An insert block 310 is inserted into the inner wall of the convex block 309. A moving rod 311 is fixedly connected to the side of the insert block 310 away from the convex block 309. An extension block 312 is slidably connected to the outer surface of the moving rod 311. The extension block 312 fixes the moving rod 311 in position to prevent it from disengaging from the locking mechanism 3, ensuring that the locking mechanism 3 can function normally and stably. The outer surface of the extension block 312 is fixed to the outer surface of the refrigerator compartment 102. A second spring 313 is fixedly connected to one side of the extension block 312 that is close to each other. The end of the second spring 313 away from the extension block 312 is fixedly connected to the outer surface of the insert block 310. The inner side of the second spring 313 is sleeved with the outer surface of the moving rod 311. The moving rod 311 restricts the movement trajectory of the second spring 313, so that the second spring 313 can only move along the moving rod 311, preventing the second spring 313 from tilting during movement, and ensuring that the insert block 310 can stably perform initial positioning of the revolving door 209.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed by the staff, the rotating door 209 opens, pushing the sealing plate 208. At this time, the sealing plate 208 causes the sliding strip 207 to slide on the refrigerated compartment 102. Simultaneously, the sliding strip 207 also causes the slider 203 to slide within the slide groove 202. Then, the slider 203 pushes the fixing rod 204, causing it to slide within the connecting block 201. Simultaneously, the slider 203 also compresses the spring 205. When the rotating door 209 closes, the spring 205 rebounds, sealing the compartment. When the sealing plate 208 resets, it seals the gap between the revolving door 209 and the refrigerated compartment 102, effectively preventing external temperature from entering and reducing temperature fluctuations within the refrigerated compartment 102. This ensures that cold air within the refrigerated compartment 102 does not leak, thus extending the freshness and quality of the goods. When the revolving door 209 closes, it moves the frame 306 and the retaining strip 307, causing the frame 306 and the retaining strip... When blocks 307 overlap, the locking strip 307 also causes the protruding block 309 to slide into the connecting block 308 on the frame 306. At this time, the protruding block 309 pushes the insert block 310, causing it to move upward. Then, the insert block 310 drives the moving rod 311 to slide within the extension block 312, while also compressing the spring 313. When the protruding block 309 is fully inserted into the connecting block 308, the spring 313 will rebound, causing the insert block 310 to lock within the protruding block 309. At the same time, the handle 210 will also activate the lock. When block 1 301 and locking block 2 302 move, locking block 2 302 will cause the limiting strip 303 to slide into locking block 1 301. Then, the bolt 304 is tightened in the limiting strip 303 and locking block 1 301 to further fix the rotating door 209. This achieves the effect of positioning the rotating door 209 first and then locking it, which can ensure that the contact between the refrigerated compartment 102 and the rotating door 209 is more precise, avoiding poor sealing caused by installation errors or improper operation, and reducing the effect of operation errors or incomplete sealing caused by inaccurate installation.
