Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically to a tea transport vehicle capable of refrigerated transport. Background Technology

[0002] With the continuous expansion of the global tea trade and the upgrading of consumer demand for quality, ensuring the quality of tea during transportation has become a core challenge for the industry chain. Traditional tea transportation mostly uses ordinary trucks or general-purpose refrigerated vehicles. During transportation, factors such as sudden braking or road bumps can cause stacked tea boxes to collapse. Tea boxes falling from heights will suffer crushing damage due to the impact.

[0003] The authorization announcement number is CN221718409U, which discloses a refrigerated tea transport vehicle. This vehicle, through an adjustment mechanism, can secure stacked tea boxes inside. A threaded rod drives a threaded sleeve block, indirectly moving the first baffle to ensure tight securing of the tea boxes without compressing the tea inside. An auxiliary mechanism is provided to cooperate with the adjustment mechanism, ensuring that the first and second baffles better secure the tea boxes. However, the above-mentioned transport device uses stacked tea boxes for transport. Research shows that when the transport temperature deviates from the optimal range by 3°C, the oxidation rate of tea polyphenols in the tea increases by 2.7 times, directly leading to browning of the tea liquor and loss of freshness. During transport, the tea on the outer edges maintains a stable temperature, but the tea boxes at the bottom center suffer from poor cold air transfer due to obstruction from other tea boxes, making it difficult to achieve uniform low-temperature transport of the inner tea boxes. Utility Model Content

[0004] The purpose of this utility model is to provide a refrigerated tea transport vehicle to solve the problem that it is not convenient to uniformly refrigerate and transport tea in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

The top of the mounting tube is provided with a stop mechanism for limiting the mounting shaft. The side of the connecting plate away from the fixing belt is provided with a fixing mechanism that is detachably connected to the barrier plate.

[0008] Furthermore, the aforementioned stopping mechanism includes a stopping disc disposed at the top of the mounting shaft, a fixing plate disposed at the top of the mounting tube and corresponding to the stopping disc, a first screw threadedly connected to the fixing plate, a stopping block rotatably connected to the end of the first screw and in contact with the top of the mounting tube, and a torsion spring disposed between the bottom end of the mounting shaft and the inner bottom wall of the mounting tube, wherein the stopping block engages with the stopping disc.

[0009] Furthermore, the aforementioned stop plate is provided with a stop groove, and the stop block is provided with stop teeth that mesh with the stop groove.

[0010] Furthermore, the aforementioned base plate is provided with several ventilation slots spaced apart.

[0011] Furthermore, the aforementioned fixing mechanism includes a limiting post disposed on the side of the connecting plate away from the fixing band and inserted into the barrier plate, a snap-fit ​​plate disposed on the side wall of the connecting plate and symmetrically distributed on the upper and lower sides of the limiting post, a first square tube disposed on the side of a snap-fit ​​plate away from the limiting post, a limiting block slidably disposed in the first square tube, and a return spring disposed between the bottom of the limiting block and the inner bottom wall of the first square tube, wherein the top end of the limiting block passes through the corresponding snap-fit ​​plate and extends to the outside.

[0012] Furthermore, the spacing between the two snap-fit ​​plates is matched with the height of the rod on the corresponding barrier plate.

[0013] Furthermore, the aforementioned barrier plate is provided with a number of limiting holes at intervals corresponding to the limiting posts.

[0014] Furthermore, the side wall of the aforementioned barrier plate is fitted with a fixing rod arranged along the width of the vehicle body. A sliding rod is slidably arranged on the fixing rod along its length direction. The end of the sliding rod away from the fixing rod is fitted with a guide sliding rod. The top end of the sliding rod is threaded with a second screw for pressing against the fixing rod. The top end of the fixing rod is threaded with a third screw for pressing against the barrier plate.

[0015] Furthermore, the bottom of the aforementioned barrier plate is symmetrically provided with a first fixing block, the top of the base plate is provided with a first guide groove that slides with the first fixing block, a first fixing installation groove is provided on one side of the first guide groove, and an electric push rod for pushing the first fixing block to move in the first guide groove is installed in the first fixing installation groove.

[0016] Furthermore, a second fixing block is provided at the bottom of the aforementioned mounting tube, and a second guide groove is provided at the top of the base plate to slide with the second fixing block.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model features a sliding baffle plate inside the vehicle body, which allows for adjustment of the vehicle's internal width, facilitating the securing of the tea box. A sliding mounting tube with a mounting shaft inside, a winding drum on the shaft, and a fixing strap wound around the drum, with the end of the strap extending through the mounting tube and connecting to a connecting plate, along with a stop mechanism, limits and secures the mounting shaft. The fixing mechanism also facilitates connection between the connecting plate and the baffle plate, securing the stretched fixing strap and limiting the outer side of the tea box. Furthermore, the baffle plate's orientation is perpendicular to the stretching direction of the fixing strap, further limiting the tea box and preventing tilting during transport. The fixing strap can be quickly retracted during unloading.

[0019] 2. This utility model, by setting a stop mechanism, stretches the fixing belt and connects the connecting plate to one side of the barrier plate through the fixing mechanism. During the stretching process, the fixing belt drives the mounting shaft to rotate through the winding drum. By rotating the first screw, the stop block moves along the direction of the stop disc. When the stop disc engages with the stop block, the mounting shaft is limited. When it is necessary to wind up the fixing belt, the first screw is rotated and the stop disc is not engaged with the stop block. Under the elastic force of the torsion spring, the mounting shaft is driven to rotate in the opposite direction and reset, so that the fixing belt can be wound on the winding drum, which is convenient to use.

[0020] 3. This utility model, by setting a fixing mechanism, moves the connecting plate along the direction of the barrier plate during use, and inserts the limiting post into the limiting hole on the barrier plate. During the insertion of the limiting post, the barrier plate will squeeze the limiting block and make the limiting block slide along the inside of the first square tube. When the limiting post is fully inserted into the limiting hole, the limiting block is reset under the action of the reset spring pad and extends to the outside of the snap-fit ​​plate. The barrier plate is snapped into the post by the two snap-fit ​​plates and the limiting block.

[0021] This utility model, by setting a fixed rod and a sliding rod, facilitates the division of the tea boxes inside the vehicle into several stacks, and sets several ventilation slots at the upper part of the bottom plate, so as to facilitate the uniform refrigerated transportation of the tea inside the tea boxes.

Detailed Implementation

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] like Figures 1 to 7As shown, this embodiment of the present invention provides a refrigerated tea transport vehicle, including a vehicle body 10, fixed sliding rods 11 disposed between the top two side walls of the vehicle body 10, the fixed sliding rods 11 in this embodiment being arranged along the width direction of the vehicle body 10, and having two sets of fixed sliding rods 11, respectively located on the top sides of the front end and the top sides of the rear end of the vehicle body 10, a door 12 disposed on the rear side of the vehicle body 10; a bottom plate 13 disposed on the inner bottom wall of the vehicle body 10, the size of the bottom plate 13 matching the internal dimensions of the vehicle body 10; and a sliding... A baffle plate 14 is slidably mounted on the top of the base plate 13 and slidably engaged with the fixed slide rod 11. The baffle plate 14 slides along the width direction of the base plate 13 and is arranged along the length direction of the vehicle body 10. A first fixing block 35 is symmetrically arranged at the bottom of the baffle plate 14. A first guide groove is formed at the top of the base plate 13, which slidably engages with the first fixing block 35. A first fixing mounting groove is formed on one side of the first guide groove, and an electric push rod 15 is installed in the first fixing mounting groove to push the first fixing block 35 to move within the first guide groove. The extension and retraction of the electric push rod 15 drives the baffle plate 14 to reciprocate along the base plate 13. Several ventilation slots are spaced apart on the base plate 13 to facilitate uniform refrigerated transport of the tea inside the tea box.

[0032] Specifically, a number of guide slide rods 21 parallel to the baffle plate 14 are spaced from top to bottom on one side inner wall of the vehicle body 10. The guide slide rods 21 are arranged along the length of the vehicle body 10. An installation tube 20 that slides with the guide slide rods 21 is slidably installed on the bottom plate 13. The installation tube 20 is vertically installed and slides along the length of the bottom plate 13. The installation tube 20 is provided with sliding holes that match the guide slide rods 21. A second fixing block 36 is provided at the bottom of the installation tube 20, and a second guide is provided at the top of the bottom plate 13 that slides with the second fixing block 36. The second guide groove has a motor 23 installed inside one side. The output shaft of the motor 23 is connected to a threaded rod 22 that is threadedly engaged with the second fixing block 36. The end of the threaded rod 22 away from the motor 23 is rotatably engaged with the inner wall of the other side of the second guide groove. The threaded rod 22 and the inner wall of the second guide groove are engaged through a shaft hole to achieve rotation. The second fixing block 36 has a threaded hole that matches the threaded rod 22. When the motor 23 rotates, it will drive the threaded rod 22 to rotate, which will drive the second fixing block 36 to move along the second guide groove, so as to realize the sliding of the mounting tube 20 on the base plate 13.

[0033] An installation shaft 18 is rotatably mounted inside the installation tube 20. The installation tube 20 is hollow inside, and its top wall has a shaft hole. A rotating shaft is vertically mounted on the top of the installation shaft 18. The rotating shaft is rotatably engaged with the shaft hole on the top wall of the installation tube 20 and extends outward along the top end. Several take-up drums 17 are spaced apart from top to bottom on the outer wall of the installation shaft 18. The take-up drums 17 are fixed to the outer wall of the installation shaft 18. A fixing strap 16 is wound around the outer wall of the take-up drums 17. The end of the fixing strap 16 away from the take-up drums 17 extends out of the installation tube 20 and is connected to the connecting plate 26. A through groove is opened on the side wall of the installation tube 20 to facilitate the passage of the fixing strap 16. The connecting plate 26 is located on the outside of the installation tube 20, and the unfolding direction of the fixing strap 16 is perpendicular to the sliding direction of the barrier plate 14. A stop mechanism for limiting the installation shaft 18 is provided at the top of the installation tube 20. A fixing mechanism that is detachably connected to the barrier plate 14 is provided on the side of the connecting plate 26 away from the fixing strap 16. In this embodiment, the winding drum 17 is provided with three sets, the corresponding fixing belt 16 is also provided with three sets, and the through groove on the side wall of the mounting tube 20 is also provided with three sets.

[0034] like Figure 4 and Figure 5 As shown, the stopping mechanism includes a stop disc 24 disposed at the top of the mounting shaft 18, the stop disc 24 being fixed to the top of the rotating shaft on the mounting shaft 18; a fixing plate disposed at the top of the mounting tube 20 and corresponding to the stop disc 24; a first screw 37 threadedly connected to the fixing plate, the fixing plate having a threaded hole for threaded engagement with the first screw 37; a stop block 25 rotatably connected to the end of the first screw 37 and in contact with the top of the mounting tube 20, the side wall of the stop block 25 having a mounting hole, a bearing being disposed in the mounting hole, and the end of the first screw 37 having a connecting shaft for engagement with the bearing, thereby achieving rotational engagement between the stop block 25 and the first screw 37; and a torsion spring 19 disposed between the bottom end of the mounting shaft 18 and the inner bottom wall of the mounting tube 20, the stop block 25 engaging with the stop disc 24. The stop block 25 has an arc-shaped structure on the side facing the stop plate 24; the stop plate 24 has a stop groove, and the stop block 25 has stop teeth that mesh with the stop groove.

[0035] In use, when refrigerated transportation of tea is required, the electric push rod 15 is activated according to the width of the tea box. The output end of the electric push rod 15 drives the baffle plate 14 to move, thereby limiting and fixing the tea box inside the vehicle body 10. After the tea box is placed, the motor 23 is activated according to the distance between the tea box near the door 12 and the door 12. The output end of the motor 23 drives the threaded rod 22 to rotate, thereby causing the mounting tube 20 to move along the axis of the guide slide rod 21. Then, the connecting plate 26 is pulled to unfold the fixing strap 16. During the unfolding process, the fixing strap 16 will cause the winding drum 17 to drive the mounting shaft 18 to rotate. After the fixing strap 16 is unfolded, the connecting plate 26 is connected to the baffle plate 14 through the fixing mechanism. At the same time, the first screw 37 is rotated and the stop block 25 is moved along the direction of the stop plate 24 until the stop block 25 engages with the stop plate 24, thereby limiting the mounting shaft 18. When it is necessary to remove the fixing strap 16, rotate the first screw 37 to release the stop block 25 from the stop plate 24. Under the action of the torsion spring 19, a pulling force is generated on the connecting plate 26. At this time, the connecting plate 26 releases the barrier plate 14 through the fixing mechanism, and the fixing strap 16 is wound around the take-up drum 17, and the mounting shaft 18 is reset. It is worth noting that the vehicle body 10 in this application is an existing component with a cooling component inside. The figure is only a schematic diagram. The actual installation of the cooling component and the specific structure of the vehicle body 10 can be selected according to actual use, and will not be described in detail here.

[0036] like Figure 4 and Figure 6 As shown, the fixing mechanism includes a limiting post 27 disposed on the side of the connecting plate 26 away from the fixing band 16 and inserted into the barrier plate 14. The barrier plate 14 is provided with a plurality of limiting holes corresponding to the limiting post 27 at intervals. The locking plates 28 are disposed on the side wall of the connecting plate 26 and symmetrically distributed on the upper and lower sides of the limiting post 27. The distance between two locking plates 28 matches the height of the rod on the corresponding barrier plate 14. A first square tube is disposed on the side of one locking plate 28 away from the limiting post 27. A limiting block 29 is slidably disposed in the first square tube. The size of the first square tube is slightly larger than the size of the limiting block 29. A return spring 30 is disposed between the bottom of the limiting block 29 and the inner bottom wall of the first square tube. The top of the limiting block 29 passes through the corresponding locking plate 28 and extends to the outside. The distance between the external limiting block 29 and the connecting plate 26 matches the thickness of the rod on the barrier plate 14. The end of the external limiting block 29 has an arc-shaped structure. In use, when it is necessary to fix the connecting plate 26, pull the connecting plate 26, and the connecting plate 26 will cause the fixing belt 16 to unfold, so that the limiting post 27 is inserted into the limiting hole. During this process, the limiting block 29 slides into the first square tube. When the side wall of the connecting plate 26 is in close contact with the barrier plate 14, the limiting block 29 returns to the initial position under the action of the return spring 30, thereby fixing the connecting plate 26.

[0037] like Figure 3 and Figure 7 As shown, in another embodiment of this utility model, a fixing rod 31 arranged along the width of the vehicle body 10 is snapped onto the side wall of the barrier plate 14. The end of the fixing rod 31 facing the barrier plate 14 has a groove matching the barrier plate 14. A sliding rod 32 is slidably arranged on the fixing rod 31 along its length. The end of the sliding rod 32 away from the fixing rod 31 is snapped onto a guide slide rod 21, and the end of the sliding rod 32 facing the guide slide rod 21 also has a groove. A second screw 33 for pressing against the fixing rod 31 is threaded through the top of the sliding rod 32, and a third screw 34 for pressing against the barrier plate 14 is threaded through the top of the fixing rod 31. In this embodiment, the number of fixing rods 31 is multiple, and the number of sliding rods 32 is equal to the number of fixing rods 31. The specific number is set according to the usage requirements.

[0038] In use, when it is necessary to separate the tea boxes stacked along the length of the vehicle body 10, the fixing rod 31 is selected according to the number of tea boxes stacked along the height. The tea boxes inside the vehicle body 10 are divided into several stacks. During installation, the slot at the end of the fixing rod 31 is engaged with the partition plate 14. Then, the third screw 34 is rotated to make the third screw 34 abut against the partition plate 14, thereby fixing the fixing rod 31 to the partition plate 14. Then, according to the distance between the partition plate 14 and the guide slide rod 21, the sliding rod 32 is pulled to slide on the fixing rod 31. When the slot at the end of the sliding rod 32 engages with the guide slide rod 21, the second screw 33 is rotated to make the second screw 33 abut against the fixing rod 31, thereby fixing the fixing rod 31 to the sliding rod 32.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
