Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck technology, and more specifically, to a sunken refrigerated truck. Background Technology

[0002] In the existing technology, a type of sunken refrigerated truck has been widely used in the field of cold chain transportation. Such vehicles usually achieve convenience and stability when loading and unloading goods by embedding the refrigerated box into the sunken structure of the chassis. However, in actual use, the existing sunken refrigerated trucks still have certain shortcomings, especially in terms of drainage and cleaning of the refrigerated box.

[0003] In the cleaning and maintenance of existing sunken refrigerated trucks, the fixing and disassembly of the support sleeve and filter tube have serious structural design defects and operational safety issues. Traditional fixing and connection methods usually adopt mechanical connection forms such as threaded connection, snap-fit ​​fixing or press fit. These connection methods are prone to problems such as corrosion, jamming or deformation of the connecting parts under long-term use and low temperature environment, which makes the disassembly operation difficult or even impossible to separate normally.

[0004] The existing technical defects of the filter tube fixing process in sunken refrigerated trucks are mainly reflected in insufficient fixing accuracy, poor stability and complicated operation. The positioning mechanism of the traditional fixing system is relatively simple, usually using simple plug-in, thread tightening or buckle locking, which cannot provide sufficient positioning accuracy and fixing reliability, and it is difficult to meet the strict requirements of the filter system for the installation position.

[0032] Please see Figures 1-7 A sunken refrigerated truck includes a frame 1, on which a user component is provided. The user component includes a cargo box 2 and a body 3. The cargo box 2 is mounted on the frame 1, and the body 3 is located at one end of the cargo box 2. Wheels 4 are mounted on the frame 1. A door 5 is rotatably connected to the cargo box 2. Drainage holes 6 are provided at the four corners of the bottom of the cargo box 2. A replacement component is provided at the bottom of the cargo box 2. The replacement component includes a support sleeve 7 and an unlocking ring 8. The support sleeve 7 is located at the bottom of the cargo box 2, and the unlocking ring 8 is slidably connected to the support sleeve 7. An unlocking block 9 is installed on the unlocking ring 8.

[0033] Support bars 10 are evenly installed on the carriage 2.

[0034] A support plate 11 is installed on the support bar 10.

[0035] A first spring 12 is provided between the unlocking ring 8 and the support sleeve 7, and a rotating plate 13 is rotatably connected to the support sleeve 7.

[0036] A rotating block 14 is installed on the rotating plate 13, and a rotating bar 15 is installed on the rotating block 14. The rotating bar 15 is inserted into the unlocking ring 8.

[0037] In this embodiment, the vehicle body 3 moves using the wheels 4 at the bottom and the cargo box 2 protects the items. The box to be refrigerated is then placed on the support plate 11 inside the cargo box 2. The support plate 11 is supported by the support strip 10, so that during the refrigeration process, the water flowing out flows out along the drain hole 6 without affecting the box. The water flows through the drain hole 6, along the support sleeve 7, into the filter pipe 16, and then flows out through the filter pipe 16. When the filter pipe 16 becomes clogged and needs to be replaced, the rotating plate 13 is rotated along the support sleeve 7. During the rotation, the rotating block 14 and the rotating strip 15 are rotated, causing them to move out from one end of the unlocking ring 8, thereby releasing the fixation of the unlocking ring 8.

[0038] Please see Figure 5-7As a sinking refrigerated truck implementation of the filter assembly: the support sleeve 7 is provided with a filter assembly, which includes a filter tube 16 and filter holes 17. The filter tube 16 is detachably mounted on the support sleeve 7, and the filter holes 17 are evenly opened on the filter tube 16. A sealing gasket 18 is fitted between the filter tube 16 and the support sleeve 7.

[0039] A locking groove 19 is provided on the filter tube 16, and a locking rod 20 is slidably connected to the support sleeve 7. A locking block 21 is connected to the locking rod 20, and the locking block 21 is adapted to the locking groove 19.

[0040] A second spring 22 is sleeved on the locking rod 20. The two ends of the second spring 22 are connected to the support sleeve 7 and the locking block 21. The locking rod 20 passes through the support sleeve 7 and is connected to the abutment block 23. The abutment block 23 is adapted to the unlocking block 9.

[0041] More specifically, after the unlocking ring 8 is released, the elastic potential energy of the first spring 12 between the unlocking ring 8 and the support sleeve 7 causes the unlocking ring 8 to slide along the support sleeve 7, which in turn abuts the abutting block 23. This causes the locking rod 20 at one end of the abutting block 23 to slide along the support sleeve 7. Under the elastic potential energy of the second spring 22 between the locking block 21 and the support sleeve 7, the locking block 21 is moved out of the locking groove 19 of the filter tube 16, thus releasing the fixation between the support sleeve 7 and the filter tube 16. The filter tube 16 can then be replaced. After the replacement is completed, the above operation is repeated in reverse to complete the replacement process of the filter tube 16.

[0042] In summary, during the use or operation of the overall equipment: the vehicle body 3 moves using the wheels 4 at the bottom, and the cargo box 2 protects the items. Then, the container to be refrigerated is placed on the support plate 11 inside the cargo box 2. The support plate 11 is supported by the support strip 10, so that the water flowing out during the refrigeration process flows out along the drain hole 6, thus not affecting the container. The water flows through the drain hole 6, along the support sleeve 7, into the filter tube 16, and flows out through the filter tube 16. When the filter tube 16 becomes blocked and needs to be replaced, the rotating plate 13 is rotated along the support sleeve 7. When rotating, the rotating block 14 and the rotating strip 15 are rotated, so that they are moved out from one end of the unlocking ring 8, thereby releasing the fixation of the unlocking ring 8.

[0043] After the unlocking ring 8 is released, the elastic potential energy of the first spring 12 between the unlocking ring 8 and the support sleeve 7 causes the unlocking ring 8 to slide along the support sleeve 7, which in turn abuts the abutment block 23. This causes the locking rod 20 at one end of the abutment block 23 to slide along the support sleeve 7. Under the elastic potential energy of the second spring 22 between the locking block 21 and the support sleeve 7, the locking block 21 is moved out of the locking groove 19 of the filter tube 16, thus releasing the fixation between the support sleeve 7 and the filter tube 16. The filter tube 16 can then be replaced. After the replacement is completed, the above operation is repeated in reverse to complete the replacement process of the filter tube 16.

[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
