Description

Technical Field

[0001] This utility model relates to the field of braking device technology, and in particular to a braking device for a non-powered trailer. Background Technology

[0002] With the rapid development of the logistics industry, air logistics has become one of the important methods of express delivery today. Before takeoff or after landing, air logistics aircraft need to transport express packages to the cabin or from the cabin to warehouses on the ground.

[0003] Non-powered trailers are commonly used in express delivery. After loading packages into the trailer, it can be towed for transport. Upon arrival at the destination, the trailer needs to be parked to prevent it from rolling away due to ground inclines or accidental movement before the packages can be unloaded. Traditional parking methods use braking systems to restrict tire rotation, but these systems are complex and costly. Therefore, a braking device for non-powered trailers is needed. Utility Model Content

[0004] In view of the above problems, this utility model provides a braking device for a non-powered trailer.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A braking device for a non-powered trailer is provided, including a brake bracket and a loading frame for storing the brake bracket. The loading frame is fixed to the bottom of the non-powered trailer. The brake bracket includes a fixing plate, and positioning blocks for contacting the outer sidewall of the tire are respectively provided at both ends of the fixing plate.

[0007] Furthermore, each of the two positioning blocks has an inclined surface for contacting the outer sidewall of the tire, and the two positioning blocks are rotationally symmetrical on the fixing plate.

[0008] Furthermore, a handle is welded onto one of the positioning blocks.

[0009] Furthermore, the handle is connected to the non-powered trailer by a chain.

[0010] Furthermore, an opening is provided on one side of the loading frame for the brake bracket to pass through, and a positioning plate is provided at the opening for inserting into the inside of the handle.

[0011] Furthermore, the loading frame is provided with a positioning element for fixing the brake bracket. The positioning element includes a positioning piece rotatably disposed at the opening, and an elastic element is provided inside the loading frame for driving the positioning piece to rotate and abut against the outer wall of the handle.

[0012] The beneficial effects of this utility model are as follows: the operator can remove the brake bracket from the loading frame, and then place the brake bracket on the ground and make the two fixing plates of the brake bracket contact the outer sidewall of the tire respectively, which can achieve the effect of preventing the vehicle from slipping. The braking device for non-powered trailers of this application has a simple structure and has the benefit of saving costs. Attached Figure Description

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] This application discloses a braking device for a non-powered trailer, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a brake bracket 1 and a loading frame 2 for storing the brake bracket 1, the loading frame 2 being welded to the bottom of the non-powered trailer 7. The brake bracket 1 includes a fixing plate 11, with positioning blocks 12 welded to both ends of the fixing plate 11 for contacting the outer sidewall of the tire.

[0019] In this embodiment, the brake bracket 1 is removed from the loading frame 2, and then placed on the ground with the two fixing plates 11 of the brake bracket 1 in contact with the outer sidewall of the tire, thereby preventing the vehicle from slipping. The braking device for the non-powered trailer 7 provided in this application has a simple structure and offers the advantage of cost savings.

[0020] Furthermore, each of the two positioning blocks 12 is provided with an inclined surface 121 for contacting the outer sidewall of the tire, and the two positioning blocks 12 are rotationally symmetrical on the fixing plate 11.

[0021] In this embodiment, the brake bracket 1 can be positioned according to the ground slope so that the outer sidewall of the tire can make contact with the inclined surface 121 of the positioning block 12 located at the lower elevation. By having the outer sidewall of the tire contact the inclined surface 121 of the positioning block 12, excessive local pressure on the outer sidewall of the tire can be avoided.

[0022] To facilitate the handling of brake bracket 1 by staff, a handle 3 is welded onto one of the positioning blocks 12.

[0023] To prevent the brake bracket 1 from being lost, the handle 3 is connected to the non-powered trailer 7 via a chain 4.

[0024] In this embodiment, one end of the chain 4 is welded to the non-powered trailer 7, and the other end is connected to the handle 3.

[0025] Furthermore, an opening is provided on one side of the material frame 2 for the brake bracket 1 to pass through, and a positioning plate 5 for inserting into the inside of the handle 3 is welded at the opening.

[0026] In this embodiment of the application, when the brake bracket 1 is placed into the material frame 2, the positioning plate 5 can be inserted into the inside of the handle 3 to prevent the brake bracket 1 from detaching from the material frame 2.

[0027] Furthermore, a positioning element 6 for fixing the brake bracket 1 is provided inside the material frame 2. The positioning element 6 includes a positioning piece 61 rotatably disposed at the opening. An elastic element 62 for driving the positioning piece 61 to rotate and abut against the outer wall of the handle 3 is provided inside the material frame 2.

[0028] In this embodiment, the elastic element 62 includes a spring, one end of which is welded to one end of the positioning piece 61, and the other end of which is welded to the inner wall of the loading frame 2. When the operator rotates the positioning piece 61, the spring stretches, allowing the handle 3 to be placed on the outside of the positioning plate 5. Then, by releasing the positioning piece 61, the spring contracts under its elastic force, causing the positioning piece 61 to rotate and abut against the handle 3, further improving the installation stability of the brake bracket 1 within the loading frame 2.

[0029] The implementation principle of the braking device for a non-powered trailer according to an embodiment of this application is as follows: the operator can remove the brake bracket 1 from the loading frame 2, and then place the brake bracket 1 on the ground so that the two fixing plates 11 of the brake bracket 1 contact the outer sidewall of the tire, thereby preventing the vehicle from slipping. The braking device for a non-powered trailer 7 according to this application has a simple structure and has the advantage of saving costs.
