Description

Technical Field

[0001] The utility model relates to the field of refrigerated compartments, in particular to an installation structure for an energy-saving and environment-friendly thermal insulation refrigerated compartment. Background Technique

[0002] A refrigerated compartment is a vehicle equipment specifically used for transporting goods that need to be stored at a constant temperature or low temperature.

[0003] In the prior art, in the long-distance transportation of some goods, in order to ensure the freezing or insurance of the goods, they are often transported through a refrigerated compartment. In the refrigerated compartment, the ventilation groove is crucial, which can ensure the smooth flow of cold air inside the compartment and avoid the cold air only flowing at the top of the goods, resulting in an increase in the temperature at the bottom of the compartment.

[0004] However, when installing the ventilation grooves of the existing refrigerated compartments, multiple groups of ventilation grooves with the same size are often evenly arranged and placed at the bottom of the refrigerated compartment. Due to the size of the compartment, the ventilation grooves often need to be cut to cover the bottom of the compartment. This installation method is time-consuming and laborious, and the efficiency is low. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure for an energy-saving and environment-friendly thermal insulation refrigerated compartment to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an installation structure for an energy-saving and environment-friendly thermal insulation refrigerated compartment, the installation structure for the energy-saving and environment-friendly thermal insulation refrigerated compartment includes:

[0007] A refrigerated compartment main body, on the bottom surface of the inner wall of the refrigerated compartment main body, a central ventilation groove, a connecting ventilation groove and a boundary ventilation groove are fixedly arranged.

[0010] Preferably, a transmission rotating shaft is fixed to the side of the sliding block. The through holes at the same ends of the first transmission block and the second transmission block correspond to the transmission rotating shaft and are clamped thereon. The other ends of the first transmission block and the second transmission block are respectively movably clamped on the outer surfaces of the connecting rotating shaft and the boundary rotating shaft.

[0011] Preferably, there are multiple groups of the sliding blocks. One group of the sliding blocks is sleeved on the outer surface of the second threaded collar, and the other sliding blocks are sleeved on the outer surface of the first threaded collar. Threaded holes are formed inside the sliding blocks.

[0012] Preferably, support holes are formed on the surface of the central ventilation groove, and annular grooves are formed on the inner walls of the support holes.

[0027] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0028] Embodiment 1, please refer to Figures 1-6 , the present utility model provides a technical solution: an installation structure for an energy-saving and environment-friendly insulated refrigerated truck body. The bottom surface of the inner wall of the refrigerated truck body 1 is fixedly provided with a central ventilation groove 2, a connecting ventilation groove 3 and a boundary ventilation groove 4. The central ventilation groove 2, the connecting ventilation groove 3 and the boundary ventilation groove 4 form the entire ventilation groove assembly. The inner wall of the boundary ventilation groove 4 is movably provided with a second transmission block 7, and the other end of the second transmission block 7 is movably provided with a slider 8. The second transmission block 7 holds and moves the boundary ventilation groove 4. The inner wall of the connecting ventilation groove 3 is movably provided with a first transmission block 6, and the other end of the first transmission block 6 is movably provided with a slider 8. The first transmission block 6 holds and moves the connecting ventilation groove 3.

[0029] A rear collar 21, a first threaded collar 22, a second threaded collar 24, and a front collar 26 are movably arranged on the outer surface of the rotating rod 9. An inner wall of the connection part of the rear collar 21, the first threaded collar 22, the second threaded collar 24, and the front collar 26 is movably provided with a connection collar 19. The connection collar 19 connects the collar assembly into a whole, and the collars are movably connected to each other. At the same time, the connection collar 19 corresponds to and is movably connected to the rotating rod 9 in a clamping manner.

[0030] On the basis of Embodiment 1, in order to realize the convenient installation of the ventilation slots at the bottom of the refrigerated carriage main body 1, a boundary rotating shaft 11 is fixed on the inner wall of the boundary ventilation slot 4. The second transmission plate 7 will push the boundary ventilation slot 4 to move towards the side of the refrigerated carriage main body 1 through the boundary rotating shaft 11. A connection rotating shaft 13 is fixed on the inner wall of the connection ventilation slot 3. The first transmission plate 6 will push the connection ventilation slot 3 to move towards the side of the refrigerated carriage main body 1 through the connection rotating shaft 13. Positioning blocks 12 are fixed on the side surfaces of the inner walls of the central ventilation slot 2 and the connection ventilation slot 3. Positioning grooves 10 are opened on the outer side surfaces of the connection ventilation slot 3 and the boundary ventilation slot 4. The positioning blocks 12 correspond to and are clamped with the positioning grooves 10, which plays a role in positioning the movement of the ventilation slots. Through holes 5 are opened on the side surfaces at both ends of the first transmission block 6 and the second transmission block 7.

[0031] A transmission rotating shaft 16 is fixed on the side part of the sliding block 8. The through holes 5 at the same end of the first transmission block 6 and the second transmission block 7 correspond to and are clamped with the transmission rotating shaft 16. The other ends of the first transmission block 6 and the second transmission block 7 are respectively movably clamped on the outer surfaces of the connection rotating shaft 13 and the boundary rotating shaft 11. The movement of the sliding block 8 will increase the angle between the transmission plate and the axis of the threaded collar. As the angle increases, the transmission plate will push the ventilation slot to move towards the side of the refrigerated carriage main body 1 through the rotating shaft.

[0032] There are multiple groups of sliding blocks 8. One group of sliding blocks 8 is sleeved on the outer surface of the second threaded collar 24, and the other sliding blocks 8 are sleeved on the outer surface of the first threaded collar 22. Threaded holes 17 are opened inside the sliding blocks 8. Due to the matching relationship between the threads and the threaded holes, when the threaded collar rotates, it will drive the sliding block 8 to move along the axis direction of the threaded collar.

[0033] Support holes 15 are opened on the surface of the central ventilation slot 2. Annular grooves 14 are opened on the inner walls of the support holes 15. Annular blocks 27 are fixed on the outer surfaces of the end parts of the rear collar 21 and the front collar 26. The annular blocks 27 correspond to and are clamped with the annular grooves 14, and the two are movably connected. The annular grooves 14 play a supporting role for the collars, and the annular grooves 14 prevent the collars from disengaging from the central ventilation slot 2.

[0034] Tooth blocks 25 are fixed on the outer surface of the rotating rod 9. Tooth grooves 23 are opened on the inner walls of the first threaded collar 22 and the second threaded collar 24. The tooth blocks 25 correspond to the tooth grooves 23. The rotating rod 9 will drive the threaded collar to rotate through the cooperation of the tooth blocks 25 and the tooth grooves 23.

[0035] A connecting block 20 is fixedly arranged on the inner wall of the port near the connection of the rear collar 21, the first threaded collar 22, the second threaded collar 24 and the front collar 26. A connection groove 18 is formed on the outer surface of the connection collar 19. The connection block 20 corresponds to the connection groove 18 and is clamped therein, showing a movable connection.

[0036] During actual use, the central ventilation groove 2, the connection ventilation groove 3, and the boundary ventilation groove 4 form the entire ventilation groove assembly. When it is necessary to install the ventilation groove at the bottom of the refrigerated truck body 1, first place the ventilation groove assembly at the bottom of the refrigerated truck body 1, and then rotate the rotating rod 9. The cooperation between the tooth block 25 and the tooth groove 23 will drive the second threaded collar 24 to rotate. Threads corresponding to the threaded holes 17 are formed on the outer surface of the threaded collar. Due to the cooperation relationship between the threads and the threaded holes, when the second threaded collar 24 rotates, it will drive the sliding block 8 to move along the axis direction of the second threaded collar 24. The movement of the sliding block 8 will increase the angle between the second transmission plate 7 and the axis of the second threaded collar 24. When the angle increases, the second transmission plate 7 will push the boundary ventilation groove 4 to move towards the side of the refrigerated truck body 1 through the boundary rotating shaft 11. When the outer side surface of the boundary ventilation groove 4 is in contact with the side of the refrigerated truck body 1, stop rotating the rotating rod 9. Then, since multiple groups of tooth blocks 25 are arranged on the surface of the rotating rod 9, multiple groups of threaded collars are arranged on the outer surface of the rotating rod 9, and the multiple groups of tooth blocks 25 are misaligned with the tooth grooves 23, so by moving the rotating rod 9 inside the collar, the front tooth block 25 can be clamped in the tooth groove 23 inside the front first threaded collar 22, and the rear tooth block 25 will disengage from the tooth groove 23 inside the rear second threaded collar 24. At this time, rotating the rotating rod 9 can drive the connection ventilation groove 3 to move left and right, so that the connection ventilation groove 3, the central ventilation groove 2, and the boundary ventilation groove 4 are evenly distributed. This installation method does not require splicing of multiple groups of ventilation grooves, nor does it require cutting of the ventilation grooves to cover the bottom of the refrigerated truck body 1, improving the installation efficiency of the ventilation grooves.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
