[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4 This utility model provides a foldable portable flatbed trailer, which includes a base plate 1, a folding and extending structure 2, and an auxiliary structure 4.

[0028] Several first universal wheels 3 are installed at the bottom of the base plate 1. Guide rails 102 are provided on the left and right sides inside the base plate 1. Grooves are opened on both sides of the upper surface of the base plate 1. Anti-slip patterns are opened on the upper surface of the base plate 1. Handle grooves 501 are opened on the upper surface of the base plate 1. Handles 5 are installed inside the handle grooves 501. The bottom end of the handle 5 is connected to the front end of the base plate 1 by a pivot. The handle 5 is a telescopic structure. The handle of the handle 5 is covered with an anti-slip sleeve. Reinforcing frames are provided at the four corners of the base plate 1. The reinforcing frames are made of aluminum alloy. The reinforcing frames can effectively prevent damage caused by collisions to the flatbed trailer and greatly extend the service life of the flatbed trailer.

[0029] The base plate 1 has a storage cavity 101 inside. The folding and extending structure 2 is installed inside the storage cavity 101. The folding and extending structure 2 includes an unfolding plate 201, a handle 202, a cavity 203, a rotating shaft 204, and rollers 205. The unfolding plate 201 is installed in the storage cavity 101 inside the base plate 1. The bottom end of the unfolding plate 201 is connected to the rotating shaft 204. The two ends of the rotating shaft 204 are connected to rollers 205. The rollers 205 are installed in the guide rails 102 on both sides inside the base plate 1. The rollers 205 and the guide rails 102 fit together. The front outer surface of the unfolding plate 201 is provided with a handle 202. The handle 202 is an embedded structure. The bottom outer surface of the unfolding plate 201 has a cavity 203. An auxiliary structure 4 is fixedly installed on the outer surface of the cavity 203.

[0030] The above structure allows the unfolding plate 201 to be pulled out by pulling the handle 202, causing the rotating shaft 204 and roller 205 to roll inside the guide rail 102, thus completing the unfolding of the flatbed trolley; conversely, the unfolding plate 201 can be retracted back into the storage cavity 101 of the base plate 1 by using the rotating shaft 204 and roller 205, thus completing the folding of the flatbed trailer.

[0031] The auxiliary structure 4 is installed at the bottom of the folding and extending structure 2. The auxiliary structure 4 includes a fixing block 401, a connecting block 402, and a second universal wheel 403. The fixing block 401 is fixedly installed on the outer surface of the cavity 203. The connecting block 402 is rotatably connected between the fixing blocks 401. The bottom end of the connecting block 402 is connected to the second universal wheel 403.

[0032] The above structure allows the second universal wheel 403 to be unfolded by rotating the connecting block 402, which can conveniently support the weight of the unfolding plate 201 and the items placed on it, and makes the movement of the flatbed trailer more stable.

[0033] The above-mentioned new foldable portable flatbed trailer design has three structural forms:

[0034] 1. Folding structure: The handle 5 is retracted and placed inside the handle groove 501 for storage. Then, the second universal wheel 403 is folded back into the cavity 203 through the connecting block 402, and the unfolding plate 201 is retracted into the storage cavity 101 inside the base plate 1, so that the flatbed trailer becomes flat, which greatly saves storage space and makes it convenient for users to carry and store.

[0035] 2. Deployment structure: Take the handle 5 out of the handle groove 501 and extend the handle 5 to a suitable length as needed. Then pull the handle 202, and roll it inside the guide rail 102 through the pivot 204 and roller 205, so that the unfolding plate 201 is pulled out from the storage cavity 101. Then, the second universal wheel 403 is unfolded through the connecting block 402, which facilitates the support of the unfolding plate 201 and the weight of the items placed on it, and makes the movement of the flatbed trailer more stable.

[0036] 3. Enclosure structure: Based on the unfolding structure, the second universal wheel 403 is folded back into the cavity 203 through the connecting block 402. Then, by rotating the pivot 204 and the roller 205, the unfolding plate is rotated ninety degrees upwards on 201, so that the unfolding plate 201 stands in the slots on both sides of the upper surface of the base plate 1, which can conveniently and effectively enclose the items on the flatbed trailer.

[0037] Working principle: The flatbed trailer can be taken out and transformed from a folding structure to an unfolded structure or a enclosure structure as needed to facilitate the transportation of goods; when not in use, the flatbed trailer can be folded up for easy storage and to reduce storage space; due to the anti-slip texture on the surface of the base plate 1 and the design of the first universal wheel 3 and auxiliary structure 4, the flatbed trailer can adapt to the needs of handling goods of different shapes and sizes, and can also move flexibly on different road surfaces, improving the versatility and practicality of the flatbed trailer.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
