Description

Technical Field

[0001] This utility model belongs to the field of refrigerated truck technology, and in particular relates to a partition door for refrigerated trucks. Background Technology

[0002] Refrigerated trucks are enclosed compartments used to transport frozen or fresh goods. Since refrigerated trucks sometimes need to store different types of goods, partition doors need to be installed between different goods to facilitate management and prevent confusion between them, thus making it easier to separate the interior space of the refrigerated truck.

[0003] Chinese utility model patent CN217892630U discloses a partition door for a refrigerated truck compartment. The partition door folds and retracts, reducing space occupation when not in use and improving storage convenience. A moving device allows the partition door to move back and forth, facilitating the partitioning of different areas within the compartment and improving the ease of adjusting storage space to meet varying needs. However, this device uses a rotating mechanism for opening and closing the partition door, requiring reserved space within the compartment for rotation, which affects cargo stacking. Furthermore, when the compartment is full, the partition door is obstructed by cargo, making it difficult to open and causing inconvenience during inspection and organization.

[0004] Therefore, there is an urgent need to improve the existing partition doors of refrigerated trucks and provide a partition door with a folding function for refrigerated trucks. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a partition door for refrigerated truck compartments that is reasonably designed, simple in structure, has a folding function, and is more convenient to open and close, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A partition door for a refrigerated truck compartment includes a truck compartment body. A servo motor is fixedly installed on the inner top surface of the truck compartment body. A long lead screw is fixedly connected to the output end of the servo motor. A movable plate is threaded onto the outer side of the long lead screw. A limit rod is fixed to the outer wall of the top front of the movable plate. A multi-section electric push rod is fixedly installed on the outer wall of the front end of the movable plate. A movable bracket is fixedly connected to the telescopic end of the multi-section electric push rod. The top end of the movable bracket is slidably sleeved on the outer side of the limit rod. A partition door assembly is provided at the bottom of the movable plate. The partition door assembly includes a first partition fixed to the bottom front end of the movable plate and multiple second and third partitions arranged at intervals. A horizontal shaft is fixed to the middle of the front end face of the second partition. A push rod assembly is installed on the outer side of the horizontal shaft. Two guide rods are symmetrically fixed to the left and right sides of the front end face of the third partition. A slider is slidably sleeved on the outer side of the guide rod. The slider and the movable bracket on the same side are on the same vertical line and are linked together.

[0007] Preferably, two long guide rods symmetrical about the long lead screw are fixedly installed on the inner side of the top of the carriage body, and the left and right ends of the movable plate are respectively slidably sleeved on the outer sides of the two long guide rods.

[0008] Preferably, the movable bracket and the multi-section electric push rod are both symmetrical about the movable plate, the two multi-section electric push rods are linked by an existing synchronous controller, and the sliding directions of the two movable brackets are always opposite to each other.

[0009] Preferably, the number of the second and third partitions is equal and there are at least two.

[0010] Preferably, the first partition, the plurality of second partitions and the plurality of third partitions are arranged in a stepped manner, and the rear outer walls of the first partition, the second partition and the third partition are symmetrically provided with grooves on the left and right sides.

[0011] Preferably, the front outer walls of the second and third partitions are symmetrically fixed with limiting protrusions, the limiting protrusions and the grooves are adapted to each other and are engaged and slidably connected.

[0012] Preferably, the push rod assembly includes a first push rod and a second push rod with bearings sleeved on the outside of the horizontal axis, and the two movable brackets and the plurality of sliders are all hingedly connected to the push rod assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, two multi-section electric push rods are synchronously retracted using an existing synchronous controller, which controls the two movable supports to slide horizontally in opposite directions along the limiting rod. At this time, the rotation of the first and second push rods facilitates the synchronous downward unfolding of multiple second and third partitions at equal intervals until the bottom third partition contacts the inner bottom surface of the carriage body, thus completing the partitioning of the carriage body. Moreover, when needed, the second and third partitions can be synchronously raised and folded, facilitating the movement and operation of staff in the two areas. Compared with the prior art, this partition door device does not occupy space when opening and closing, and can still be easily opened after the cargo is full, better meeting actual needs and being more practical.

[0014] The rear left and right outer walls of the first, second, and third partitions of this utility model are all provided with grooves, and the front left and right outer walls of the second and third partitions are all fixed with limiting protrusions. The limiting protrusions are engaged and slidably located in the corresponding grooves, which facilitates the vertical limiting between the first, second, and third partitions, ensuring the stability of the vertical opening and closing of the partition door assembly. Moreover, the rotation of the long screw can be used to control the movable plate to drive the partition door assembly to move horizontally along the long guide rod, which facilitates the adjustment of the position of the partition door assembly in the carriage body as needed.

Detailed Implementation

[0017] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings: like Figures 1-6 As shown in the figure, this utility model is used for partition doors of refrigerated truck compartments, which includes a truck body 1, a servo motor 3, and a multi-section electric push rod 8. The servo motor 3 is fixedly installed on the inner top surface of the truck body 1. The output end of the servo motor 3 is fixedly connected to a long lead screw 4 extending in the front-rear direction of the truck body 1. The outer side of the long lead screw 4 is threaded with a movable plate 5 extending in the left-right direction of the truck body 1. A limit rod 6 is fixedly fixed on the outer wall of the front top of the movable plate 5. The multi-section electric push rod 8 is fixedly installed on the outer wall of the front end of the movable plate 5. The telescopic end of the multi-section electric push rod 8 is fixedly connected to a movable bracket 7. The top of the movable support 7 is slidably sleeved on the outside of the limiting rod 6. The bottom of the movable plate 5 is provided with a partition assembly. The partition assembly includes a first partition 9 fixed to the bottom of the front end of the movable plate 5 and a plurality of second partitions 10 and third partitions 11 arranged at intervals. A horizontal shaft 12 is fixed in the middle of the front end face of the second partition 10. A push rod assembly is installed on the outside of the horizontal shaft 12. Two guide rods 13 are symmetrically fixed on the left and right sides of the front end face of the third partition 11. A slider 14 is slidably sleeved on the outside of the guide rod 13. The slider 14 and the movable support 7 on the same side of the device are on the same vertical line and are linked together.

[0018] As a preferred embodiment, based on the above structure, two long guide rods 2 that are symmetrical about the long screw rod 4 are fixedly installed on the inner side of the top of the carriage body 1, and the left and right ends of the movable plate 5 are respectively slidably sleeved on the outer sides of the two long guide rods 2.

[0019] In this embodiment, the use of two long guide rods 2 on the left and right sides can improve the stability of the movable plate 5 during the horizontal sliding adjustment process.

[0020] As a preferred embodiment, based on the above structure, the movable bracket 7 and the multi-section electric push rod 8 are both symmetrical about the movable plate 5, the two multi-section electric push rods 8 are linked by an existing synchronous controller, and the sliding directions of the two movable brackets 7 are always opposite to each other.

[0021] In this embodiment, two multi-section electric push rods 8 are used to facilitate the synchronous reverse sliding of two movable supports 7, thereby facilitating the operation of the push rod assembly and the opening and closing of the partition assembly.

[0022] As a preferred embodiment, based on the above structure, the number of the second partition 10 and the third partition 11 are equal and there are at least two.

[0023] In this embodiment, the partition door assembly is composed of a first partition 9 and multiple second partitions 10 and third partitions 11, which facilitates vertical lifting and folding opening and closing, effectively reducing the impact of the partition door opening and closing on the interior space of the carriage, and making it more practical.

[0024] As a preferred embodiment, based on the above structure, the first partition 9, the plurality of second partitions 10 and the plurality of third partitions 11 are further distributed in a stepped manner, and the rear outer walls of the first partition 9, the second partitions 10 and the third partitions 11 are symmetrically provided with grooves 17 on the left and right sides.

[0025] As a preferred embodiment, based on the above structure, the front outer walls of the second partition 10 and the third partition 11 are further symmetrically fixed with limiting protrusions 18, and the limiting protrusions 18 and the grooves 17 are adapted to each other in size and are engaged and slidably connected.

[0026] In this embodiment, the limiting protrusion 18 engages and slides within the corresponding groove 17, facilitating vertical positioning between the first partition 9, the second partition 10, and the third partition 11, and ensuring the vertical opening and closing stability of the partition door assembly.

[0027] In a preferred embodiment, based on the above structure, the push rod assembly further includes a first push rod 15 and a second push rod 16 with bearings sleeved on the outside of the horizontal shaft 12, and two movable brackets 7 and multiple sliders 14 are all hinged to the push rod assembly.

[0028] In this embodiment, the rotation of the first push rod 15 and the second push rod 16 facilitates the control of the multiple second partitions 10 and the third partitions 11 to move down and unfold or to rise and fold up simultaneously.

[0029] The working principle of this utility model is as follows: In use, first, the servo motor 3 is turned on to control the rotation of the long lead screw 4, which in turn controls the movable plate 5 to drive the partition assembly to slide horizontally along the long guide rod 2, making it easy to move the partition assembly to the designated position inside the carriage body 1. After the goods are loaded, the existing synchronous controller can be used to control the two multi-section electric push rods 8 to start retracting synchronously. At this time, the two movable brackets 7 can be controlled to slide synchronously along the limit rod 6 and move closer to each other. During this process, the first push rod 15 and the second push rod 16 in the push rod assembly can rotate in opposite directions around the corresponding horizontal axis 12. At this time, the slider 14 slides along the guide rod 13, thereby pushing multiple second partitions 10 and multiple third partitions 11 to move down synchronously and unfold at equal intervals. Figure 4As shown in the diagram, the interior of the carriage body 1 can be quickly and conveniently partitioned until the bottom third partition 11 contacts the inner bottom surface of the carriage body 1. Similarly, when needed, the two movable supports 7 can be controlled to slide and move away by the two multi-section electric push rods 8, thereby controlling the second partition 10 and the third partition 11 to rise, fold, and retract synchronously, making it convenient for staff to walk and work in the two areas. Compared with the prior art, the opening and closing of this partition door device does not occupy space and can still be easily opened after the goods are full, which can better meet the actual market demand. The device is more practical. Moreover, during the vertical lifting and opening and closing process of the partition door assembly, the grooves 17 opened on the left and right outer walls of the rear end of the first partition 9, the second partition 10 and the third partition 11, and the limiting protrusions 18 fixed on the left and right outer walls of the front end of the second partition 10 and the third partition 11 can be used to lock and slide in the corresponding grooves 17, which can vertically limit the first partition 9, the second partition 10 and the third partition 11, and effectively improve the stability of the vertical opening and closing process of the partition door assembly. It should be noted that the circuit layout and power supply methods of the electrical appliances in this device adopt existing technologies, and the specific control methods of the servo motor 3 and the two multi-section electric push rods 8 adopt existing mature methods, which are not the key innovation directions of this case, so they will not be described in detail.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
