DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described in combination with specific embodiments.

[0024] Please refer to Figures 1 to 5 The utility model provides a technical scheme: a cold accumulation type constant temperature refrigeration vehicle, including vehicle body 1, be provided with carriage 2 on vehicle body 1, and the inner chamber of this carriage 2 is refrigeration area 201, and the tail of carriage 2 is provided with tail door 6, and after opening tail door 6, can carry out the loading and unloading operation to carriage 2, wherein the inside or outside of carriage 2 can install refrigerating unit and fan group, and fan group guides the air after refrigerating of refrigerating unit into carriage 2, and the temperature in the carriage 2 is reduced to the temperature interval for refrigeration.

[0025] ​The at least one partition 3 is arranged in the vehicle compartment 2 in front of and behind the partition 3, and in the embodiment, the number of the partition 3 is one. The partition 3 separates the refrigeration area 201 into a front refrigeration area 2011 and a rear refrigeration area 2012. The front refrigeration area 2011 and the rear refrigeration area 2012 are arranged according to the delivery order of the refrigeration goods. When the tail door 6 is opened, the goods in the rear refrigeration area 2012 are in contact with the outside air. At this time, due to the isolation effect of the partition 3, the goods in the front refrigeration area 2011 are in a constant temperature refrigeration state. The top of the partition 3 is rotationally connected to the top of the vehicle compartment 2, and the outer periphery of the partition 3 is sealingly connected to the inner wall of the vehicle compartment 2. In the specific implementation, a sealing gasket can be bonded to the outer periphery of the partition 3. When the partition 3 swings to the rear of the vehicle to an approximately horizontal state, the partition 3 is in a completely open state. At this time, the front refrigeration area 2011 and the rear refrigeration area 2012 form a complete refrigeration area 201.

[0026] The refrigeration pipe 4 is embedded in the vehicle compartment 2. One end of the refrigeration pipe 4 is connected to the transmission pipe of the fan group. The refrigeration pipe 4 is connected with bypass pipes 41 located in the front refrigeration area 2011 and the rear refrigeration area 2012, respectively. The bypass pipes 41 are provided with axially distributed air outlet holes 411. The fan group transports the refrigeration air generated by the refrigeration unit into the refrigeration pipe 4. The refrigeration air is transported into the front refrigeration area 2011 and the rear refrigeration area 2012 through the bypass pipes 41. At this time, the goods can be normally refrigerated at a low temperature.

[0027] Specifically, the refrigeration pipe 4 is embedded in the inside of the top of the vehicle compartment 2. The bypass pipes 41 are located below the inner top wall of the vehicle compartment 2. The bypass pipes 41 are slidingly connected with hooks 5 in front of and behind the bypass pipes 41. The rear side of the partition 3 is fixedly connected with handles 31 which are hung and matched with the hooks 5. When the partition 3 is opened, the adjacent hook 5 is slid backward. The hook 5 will hook the handle 31. At this time, it can be ensured that the partition 3 is stably and constantly opened. When the partition 3 is closed, it is closed by gravity. In use, a common latch mechanism can be installed on the partition 3 and the bottom of the vehicle compartment 2. The purpose is to ensure that the partition 3 is in a locked state after being closed. It should be noted that when the partition 3 is opened by rotating to the rear, the hook 5 is arranged on the bypass pipe 41 close to the partition 3, and the other bypass pipes 41 do not need to be matched with the hook 5.

[0028] Further, the hook 5 includes a sliding sleeve 51 and an L-shaped rod 52. The sliding sleeve 51 is sleeved on the bypass pipe 41, and the bottom of the sliding sleeve 51 is welded to one end of the L-shaped rod 52. The handle 31 is a groove type structure, and one side of the handle 31 is welded with a hook ring 311 which is matched with the L-shaped rod 52. When the short rod on the L-shaped rod 52 is inserted into the hook ring 311, the partition 3 will be hooked.

[0029] In the embodiment, the rectangular passage 33 is formed in the partition plate 3, and the outer side of the partition plate 3 is slidably connected with the sealing door 7 which seals the rectangular passage 33. In the specific implementation, the outer side of the partition plate 3 is preferably welded with the track groove 34 located on the upper and lower sides of the rectangular passage 33, and the upper and lower ends of the sealing door 7 are fixedly connected with the sliding block 71 which slidably cooperates with the track groove 34. That is, the sliding sealing door 7 can control the opening and closing of the rectangular passage 33. This kind of arrangement makes the refrigerated vehicle enter the front refrigeration area 2011 without opening the partition plate 3, which is suitable for the situation of temporary entering the front refrigeration area 2011 for security check and small amount of goods distribution, and makes the distribution more flexible.

[0030] In the embodiment, the sealing door 7 is provided with the sealing rubber strip 72 which cooperates with the partition plate 3. This kind of arrangement can improve the sealing degree of the sealing door 7 after sealing the rectangular passage 33.

[0031] In the embodiment, the outer side of the sealing door 7 is fixedly connected with the push-pull rod 73 which is an operating part for manually sliding the sealing door 7.

[0032] Working principle: When temporary security check is needed in the front refrigeration area 2011 during the distribution process, the tail door 6 is opened, the security personnel enters the vehicle compartment 2, and then the tail door 6 is closed. The security personnel manually opens the sealing door 7 through the push-pull rod 73, and then enters the front refrigeration area 2011 through the rectangular passage 33 after the rectangular passage 33 is opened. Thus, all refrigerated goods can be checked. When goods need to be distributed and unloaded, the tail door 6 is opened, and the goods in the rear refrigeration area 2012 are unloaded, while the partition plate 3 remains closed. At this time, the goods in the front refrigeration area 2011 are still in the constant temperature refrigeration state.

[0033] In addition, it should be understood that although the present specification is described in terms of embodiments, each embodiment does not necessarily contain only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments which can be understood by those skilled in the art.
