Description

Technical Field

[0001] This utility model relates to the field of logistics vehicle technology, and in particular to a logistics vehicle with a bidirectional traction structure. Background Technology

[0002] With the development of e-commerce and express delivery industries, logistics vehicles are playing an increasingly important role in urban distribution. Logistics vehicles are typically used for the delivery, transportation, and handling of various goods and materials. In the modern logistics industry, there are various types and configurations of logistics vehicles. Large warehouses usually use logistics vehicles with traction structures to facilitate the rapid transfer of goods within the warehouse.

[0003] However, most existing towing logistics vehicles can only be used to tow one end of the tractor in actual use. When used in warehouses, it is usually inconvenient to turn the tractor around, which affects the actual user experience. In addition, in order to make the logistics vehicle more stable when towing, the front wheels can turn freely. Some existing logistics vehicles have towing hooks added to both the front and rear, but this method will result in insufficient steering sensitivity in actual use, which will affect the actual user experience. Therefore, the above problems need to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a logistics vehicle with a bidirectional traction structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A logistics vehicle with a bidirectional traction structure includes a chassis, a fixed frame fixedly connected to the top of the chassis, door panels symmetrically mounted on both sides of the fixed frame, a horizontally sliding crossbar connected to the bottom of the chassis, and traction holes vertically opened at both ends of the crossbar. Rollers are installed at the four corners of the bottom of the chassis, and a connecting mechanism for the four rollers is provided at the bottom of the chassis. Two horizontal plates are fixedly connected to both ends of the bottom of the chassis, and the two horizontal plates contain limiting mechanisms that restrict the rotation of the four rollers. The crossbar can be slid horizontally during use, allowing traction from both ends of the device. T-shaped pins further restrict the sliding of the crossbar. Simultaneously, the four connecting rods allow the four limiting rods to slide, thereby restricting the rotation of two rollers and releasing the rotation of the other two rollers, thus improving the device's effectiveness.

[0007] Preferably, the connecting mechanism includes four fixed sleeves. The four fixed sleeves are vertically fixed to the four corners of the bottom of the vehicle floor plate, and are fixed to both ends of two horizontal plates. Connecting plates are fixedly connected to the top ends of the two fixed sleeves. Fixed posts are rotatably fitted inside each of the four fixed sleeves. A second circular hole is horizontally opened through the surface of each of the four fixed posts. Connecting sleeves are fixedly connected to the bottom of each of the four fixed posts. Four rollers are rotatably connected inside the four connecting sleeves to connect the four rollers and restrict their rotation.

[0008] Furthermore, the limiting mechanism includes limiting rods. Four fixed sleeves each have a horizontally opened first circular hole, which corresponds to four second circular holes. Four limiting rods are provided, each slidably connected to the interior of one of the four connecting plates. Two horizontally opened grooves are provided at the top of the horizontal plate, each groove containing a sliding plate. One end of each of the four limiting rods is fixedly connected to another end of the four limiting rods. The ends of the four limiting rods, which are far apart from each other, respectively engage with the four first and four second circular holes. Two limiting plates are vertically fixedly connected to the top of each of the two horizontal plates. The tops of the four limiting plates are fixedly connected to the bottom of the vehicle floor. A horizontal sliding rod connects between every two limiting plates. Connecting blocks are fixedly connected to both symmetrical sides of the horizontal rod surface. Each connecting block contains a hinged connecting rod. One end of each of the four connecting rods is hinged to the surface of one of the four sliding plates, used to slide the four limiting rods. This allows two of the limiting rods to slide into the corresponding two second circular holes, thereby limiting the rotation of the rollers, while simultaneously allowing the other two limiting rods to slide out of the corresponding two traction holes.

[0009] Preferably, the top of the vehicle floor has vertically formed through holes at both ends. The two through holes are respectively matched with two traction holes. A T-shaped pin is installed in one of the through holes. The T-shaped pin is inserted into one of the traction holes and is used to install the T-shaped pin in one of the through holes and the traction hole, thereby restricting the sliding of the crossbar.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. When in use, the crossbar can be slid horizontally, allowing it to be slid towards the end that needs to be pulled. The device can then be pulled through the traction hole. Subsequently, a T-shaped pin is installed inside the through hole and traction hole at the other end of the device to restrict the crossbar. This allows the device to be pulled from both ends, thereby improving its effectiveness.

[0012] 2. When in use, the sliding of the crossbar can restrict the rollers at both ends of the device, allowing the two rollers closer to the traction end to turn freely, while restricting the two rollers farther from the traction end, thus making the device more stable when traction.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5 A logistics vehicle with a bidirectional traction structure includes a chassis 1. A fixed frame 11 is fixedly connected to the top of the chassis 1. Door panels 12 are symmetrically installed on both sides of the fixed frame 11. A horizontal crossbar 3 is horizontally slidably connected to the bottom of the chassis 1. Traction holes 32 are vertically opened at both ends of the crossbar 3. Rollers 2 are provided at the four corners of the bottom of the chassis 1. A connecting mechanism for connecting the four rollers 2 is provided at the bottom of the chassis 1. Two horizontal plates 15 are fixedly connected to both ends of the bottom of the chassis 1. The two horizontal plates 15 have a limiting mechanism inside that restricts the rotation of the four rollers 2. The crossbar 3 can be horizontally slid during use, so that the device can be tractioned at both ends. The sliding of the crossbar 3 can be restricted by the T-shaped pin 5. At the same time, the four connecting rods 42 can slide the four limiting rods 4, thereby restricting the rotation of two of the rollers 2 and releasing the rotation of the other two rollers 2, thus improving the use effect of the device.

[0021] Reference Figure 2 and Figure 3 In a preferred embodiment, the connecting mechanism includes four fixing sleeves 13. The four fixing sleeves 13 are vertically fixed to the four corners of the bottom of the vehicle floor 1. The four fixing sleeves 13 are fixed to the two ends of the two horizontal plates 15. The top ends of the two fixing sleeves 13 are fixedly connected to the connecting plates 17. The four fixing sleeves 13 are rotatably fitted with fixing posts 22 inside each of the four fixing posts 22. The surfaces of the four fixing posts 22 are horizontally perforated with second circular holes 23. The bottoms of the four fixing posts 22 are fixedly connected to the connecting sleeves 21. The four rollers 2 are rotatably connected to the four connecting sleeves 21 to connect the four rollers 2 and restrict the rotation of the four rollers 2.

[0022] Reference Figure 3 and Figure 4 In a preferred embodiment, the limiting mechanism includes limiting rods 4. Four fixing sleeves 13 each have horizontally opened first circular holes 14, which correspond to four second circular holes 23. Four limiting rods 4 are provided, each slidably connected to the interior of one of the four connecting plates 17. Two horizontal grooves 18 are opened at the top of the horizontal plate 15, and sliding plates 41 are slidably connected inside each of the four grooves 18. One end of each of the four limiting rods 4 is fixedly connected to another end of the four limiting rods 4. The ends of the four limiting rods 4 that are far apart from each other respectively cooperate with the four first circular holes 14 and the four second circular holes 23. The two horizontal plates 15... Two limiting plates 16 are vertically fixedly connected to the top of each of the four limiting plates 16. The top of each of the four limiting plates 16 is fixedly connected to the bottom of the vehicle floor 1. The sliding rod of the crossbar 3 is connected between each pair of limiting plates 16. Connecting blocks 31 are fixedly connected to both sides of the surface of the crossbar 3. Each connecting block 31 has a connecting rod 42 hinged inside. One end of each of the four connecting rods 42 is hinged to the surface of the four sliding plates 41, which is used to slide the four limiting rods 4. This allows two of the limiting rods 4 to slide into the corresponding two second circular holes 23, thereby restricting the rotation of the roller 2. At the same time, it allows the other two limiting rods 4 to slide out of the corresponding two traction holes 32.

[0023] Reference Figure 4 and Figure 5 In a preferred embodiment, the top two ends of the vehicle floor 1 are vertically provided with through holes 19, and the two through holes 19 are respectively matched with two traction holes 32. A T-shaped pin 5 is installed in one of the through holes 19. The T-shaped pin 5 is inserted into one of the traction holes 32 and is used to install the T-shaped pin 5 in one of the through holes 19 and the traction hole 32, thereby restricting the sliding of the crossbar 3.

[0024] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In actual use, the horizontal bar 3 can be horizontally slidable, allowing traction at both ends of the device. The T-shaped pin 5 restricts the sliding of the horizontal bar 3. Simultaneously, the four connecting rods 42 cause the four limiting rods 4 to slide, thereby restricting the rotation of two rollers 2 and releasing the rotation of the other two rollers 2, thus improving the device's usability. When in use, the two door panels 12 on the surface of the fixed frame 11 can be opened, facilitating the placement of items inside the device. Then, the horizontal bar 3 can be slid during use. The crossbar 3 is slid towards the end that needs to be pulled, and then the T-shaped pin 5 is inserted into the through hole 19 and the pulling hole 32 at the other end to restrict the sliding of the crossbar 3. The device can then be pulled through the pulling hole 32. While the crossbar 3 is sliding, the two limiting rods 4 near the pulling end slide closer to each other through the connection of the four connecting rods 42, which will restrict the steering contact of the two rollers 2 near the pulling end. Meanwhile, the two limiting rods 4 away from the pulling end will slide away from each other, thus sliding into the two second round holes 23 and the two first round holes 14, thereby restricting the steering of the two rollers 2 away from the pulling end. This will improve the driving stability of the device during use.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
