[0002] The vehicle's connecting and traction device can be used in many factory areas, such as the transfer of logistics materials within the factory area. As the main material transportation tool within the factory area, the traction method of the logistics transport vehicle is usually achieved by manually inserting pins or manually hooking them.

[0003] However, the above method requires manual operation, and the positioning between the hole and the pin is inaccurate, requiring repeated manual adjustments to ensure proper mounting, which is inconvenient to operate. Utility Model Content

The traction frame has an open opening, and a rotating movable component is hinged to the upper end of one side of the open opening. The rotating movable component is provided with a stop shaft. The lower end of the rotating movable component contacts the lower surface of the traction frame and supports the lower end of the traction pin through the stop shaft, preventing the traction pin from falling under gravity. This ensures that the distance between the lower end of the traction pin and the traction frame allows the traction hook to extend inward to a predetermined position.

[0006] Preferably, the traction frame is a U-shaped frame.

[0007] Preferably, the upper end of the U-shaped frame is provided with a pin sleeve, and the traction pin cooperates with the pin sleeve to realize the sliding connection of the traction pin. The upper end of the traction pin has a limiting end to prevent the traction pin from falling out downwards. The lower end of the U-shaped frame is provided with a through hole corresponding to the traction pin.

[0008] Preferably, the rotating movable component is a U-shaped component, the upper end of which is rotatably connected to the upper end of the U-shaped frame via a rotating shaft assembly, and the stop shaft is horizontally connected inside the U-shaped component.

[0009] Preferably, a baffle is connected below the baffle shaft.

[0010] Preferably, the lower end of the traction pin is provided with a limiting boss.

[0011] Preferably, the top of the traction pin is provided with a connecting ring.

[0012] Beneficial effects: This utility model provides an inlet-type traction device that can realize the automatic connection of the traction device without manual operation, which is convenient to operate and relatively efficient. Attached Figure Description

[0018] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0019] Example 1:

[0020] like Figure 1-3 As shown in the figure, the present invention provides an introductory traction device, including a traction frame 1 and a traction pin 2. The traction pin 2 is slidably connected to the traction frame 1, allowing it to slide up and down, connecting and separating from the traction hook 9. The traction frame 1 has an open opening 11, and a rotating movable part 8 is hinged to the upper end of one side of the open opening 11. The rotating movable part 8 is provided with a stop shaft 3. The lower end of the rotating movable part 8 contacts the lower surface of the traction frame 1 and supports the lower end of the traction pin 2 through the stop shaft 3, preventing the traction pin 2 from falling under the action of gravity, so as to meet the distance between the lower end of the traction pin 2 and the traction frame 1, allowing the traction hook 9 to penetrate inward to a predetermined position.

[0021] Specifically, the traction frame 1 is a U-shaped frame, and the upper end of the U-shaped frame is provided with a pin sleeve 4. The traction pin 2 cooperates with the pin sleeve 4 to achieve a sliding connection of the traction pin 2. The upper end of the traction pin 2 has a limiting end 21 to prevent the traction pin 2 from falling out downwards. The lower end of the U-shaped frame is provided with a through hole 12 corresponding to the traction pin 2. The rotating movable part 8 is a U-shaped part. The upper end of the U-shaped part is rotatably connected to the upper end of the U-shaped frame through a rotating shaft assembly 5. The stop shaft 3 is horizontally connected inside the U-shaped part.

[0022] In some embodiments, to prevent the traction hook 9 from coming off the tire when it enters, a baffle 6 structure is used to increase the contact area; therefore, the baffle 6 is connected below the baffle shaft 3.

[0023] In some embodiments, to prevent the traction pin 2 from falling off after being inserted into the traction hook 9, a limiting boss 22 is provided at the lower end of the traction pin 2.

[0024] In some embodiments, the top of the traction pin 2 is provided with a connecting ring 7, which can be connected to a rope for pulling the traction pin, making it easy to operate.

[0025] The working principle or operating method of this utility model is as follows: When traction work is not being performed, the traction device is in the following state: Figure 1 As shown, the lower end of the rotating movable part 8 contacts the lower end face of the U-shaped frame, and the stop shaft 33 supports the lower end of the traction pin 2 to form a relatively stable support structure. The distance between the lower end of the traction pin 2 and the lower end face of the U-shaped frame is sufficient for the passage of the traction hook 9. When the traction hook 9 enters, it first contacts the baffle 6. Since the baffle 6, the stop shaft 3, and the rotating movable part 8 are a connected whole, when the baffle 6 moves inward to the U-shaped frame, it drives the stop shaft 3 and the rotating movable part 8 to move inward. The stop shaft 3 will gradually detach from the traction pin 2. The traction pin 2 loses the support of the stop shaft 3 and begins to fall freely downward under the action of gravity. At this time, the traction hook 9 also reaches the predetermined position. The traction pin 2 and the traction hook 9 cooperate to realize automatic traction.

[0026] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
