[0030] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0031] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0033] An embodiment of this utility model provides a foldable covered wagon, such as... Figure 1-5 As shown, the shed includes a base plate 100, a rear side frame 200, a left side frame 300, a right side frame 400, and a front side frame 500. The base plate 100 is located at the bottom of the entire shed, the rear side frame 200 is located at the rear of the entire shed, the left side frame 300 is located on the left side of the entire shed, the right side frame 400 is located on the right side of the entire shed, and the front side frame 500 is located at the front of the entire shed. The entire shed has a used state and a folded state. When the shed is in use, the base plate 100, rear side frame 200, left side frame 300, right side frame 400, and front side frame 500 can be closed to form a box-like structure. The base plate 100, left side frame 300, and right side frame 400 are all rotatably connected to the rear side frame 200, allowing them to rotate relative to the rear side frame 200. This enables the base plate 100, left side frame 300, and right side frame 400 to be folded in front of the rear side frame 200 or unfolded. The right side frame 400 is equipped with a foldable support rod 410. When the entire shed is in use, the support rod 410 can be unfolded; when the entire shed is folded, the support rod 410 can also be folded away to reduce space occupation.

[0034] A first hook 511 is provided at the top of the front frame 500, and movable locking hooks 520 are provided on both the left and right sides of the front frame 500. Because the locking hooks 520 are movable, they can hook onto a target object and also detach from it. The locking hooks 520 on the left and right sides of the front frame 500 are detachably hooked onto the left frame 300 and the right frame 400, respectively. Specifically, when the entire trolley is in use, the locking hooks 520 on the left and right sides of the front frame 500 are hooked onto the left frame 300 and the right frame 400, respectively. When the front frame 500 needs to be disassembled, the locking hooks 520 on the left and right sides are detached from the left frame 300 and the right frame 400, respectively. When the support rod 410 is extended relative to the right frame 400, the support rod 410 is located above the front frame 500, and the first hook 511 is hooked onto the support rod 410.

[0035] When the entire shed needs to be folded, the locking hook 520 can be separated from the left side frame 300 and the right side frame 400, and the first hook 511 can be removed from the support rod 410, so that the front side frame 500 can be detached. The left side frame 300 and the right side frame 400 can be rotated and folded relative to the rear side frame 200. Since there is no interference from the front side frame 500, the left side frame 300 and the right side frame 400 can be tightly stacked together, making the folded shed more neat.

[0036] In some embodiments, such as Figure 1-5 As shown, the locking hook 520 is slidably connected to the front frame 500, and the sliding direction of the locking hook 520 and the front frame 500 is inclined relative to the vertical direction. In the downward sliding direction, the locking hook 520 located on the left side of the front frame 500 gradually moves away from the left frame 300, and the locking hook 520 located on the right side of the front frame 500 gradually moves away from the right frame 400. When it is necessary for the locking hook 520 to hook the left frame 300 and the right frame 400, the locking hook 520 is slid downward, and the two locking hooks 520 gradually move inward, thereby tightening the left frame 300 and the right frame 400 on both sides. When it is necessary for the locking hook 520 to separate from the left frame 300 and the right frame 400, the locking hook 520 is slid upward, and the two locking hooks 520 gradually move outward, thereby releasing the left frame 300 and the right frame 400, thus separating the locking hook 520 from the left frame 300 and the right frame 400.

[0037] Considering that after the locking hook 520 hooks the left frame 300 and the right frame 400, it restricts the left frame 300 and the right frame 400 from rotating outward, but the left frame 300 and the right frame 400 may rotate inward, the following two implementation methods are provided.

[0038] In one embodiment, when the foldable shed is in use, the front frame 500 is located between the left frame 300 and the right frame 400 and abuts against the left frame 300 and the right frame 400 respectively. In this way, the front frame 500 can restrict the left frame 300 and the right frame 400 from rotating inward, so that the left frame 300 and the right frame 400 remain in use.

[0039] In another embodiment, limiting members are provided on both the left and right sides of the front frame 500. When the foldable trolley is in use, the limiting members on the left and right sides of the front frame 500 abut against the inner surfaces of the left frame 300 and the right frame 400 respectively. The limiting members restrict the left frame 300 and the right frame 400 from rotating inward, and also keep the left frame 300 and the right frame 400 in use.

[0040] Further, guide rods 530 are respectively disposed on the left and right sides of the front frame 500, the extending direction of the guide rods 530 is arranged obliquely relative to the vertical direction, in the downward sliding direction, the guide rods 530 on the left and right sides of the front frame 500 gradually approach each other, the locking hook 520 is provided with a through hole, and the guide rod 530 penetrates the through hole and can slide along the through hole, thereby realizing the sliding connection between the locking hook 520 and the front frame 500. Since the locking hook 520 has a certain weight, under the action of gravity, the locking hook 520 has a tendency to move downward, so that the locking hook 520 can maintain a state of hooking the left frame 300 and the right frame 400.

[0041] In some embodiments, the locking hook 520 may be arranged transversely and bent backward, both the left frame 300 and the right frame 400 comprise vertically arranged vertical rods, and the locking hook 520 can hook the vertical rods of the left frame 300 and the right frame 400.

[0042] In some embodiments, as Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, one end of a support rod 410 is movably connected to the right frame 400, and the other end is provided with an insertion rod 411, the left frame 300 is provided with an insertion hole 320, when the support rod 410 is unfolded relative to the right frame 400, the insertion rod 411 can be inserted into the insertion hole 320. After the insertion rod 411 is inserted into the insertion hole 320, both ends of the support rod 410 can be kept fixed, so that the first hook 511 can be stably hooked on the support rod 410. Meanwhile, the left frame 300 and the right frame 400 are connected together by the support rod 410, which limits the rotation of the left frame 300 and the right frame 400, so that the left frame 300 and the right frame 400 can be kept in a use state.

[0043] In addition, since the support rod 410 is movably connected to the right frame 400, the support rod 410 is easy to move, which facilitates insertion of the insertion rod 411 into the insertion hole 320 or withdrawal of the insertion rod 411 from the insertion hole 320.

[0044] Further, a bending rod 420 is disposed on the right frame 400, both ends of the bending rod 420 are connected to the right frame 400, the support rod 410 is provided with a through opening, the bending rod 420 penetrates the opening, and the bending rod 420 can rotate and slide in the opening, which enables the support rod 410 to move flexibly and remain separated from the right frame 400.

[0045] The bending rod 420 can be in a "凵"-shaped structure, when the support rod 410 is folded for storage, the support rod 410 can be folded downward on the inner side of the right frame 400.

[0046] In some embodiments, as Figure 3 and Figure 4As shown, a hanging piece 310 is provided on the outer side of the left frame 300, and a second hook 512 is provided on the front frame 500. When the foldable shed is in the folded state, the left frame 300 overlaps the front side of the right frame 400, exposing the hanging piece 310. After the front frame 500 is removed from the left frame 300 and the right frame 400, the second hook 512 of the front frame 500 can be hooked onto the hanging piece 310, preventing the front frame 500 from completely separating from the entire shed. By hooking, the front frame 500 can also be folded and stored together with the left frame 300, making it easy to assemble the entire shed when needed.

[0047] Furthermore, the rear side frame 200 is provided with a forward-protruding connector, and the front end of the connector is provided with a hanging rod 210. When the foldable shed is in the folded state, the locking hook 520 located on the right side of the front side frame 500 hooks onto the hanging rod 210. This can restrict the left and right movement of the front side frame 500 hooked on the left side frame 300, reduce the swaying of the front side frame 500, and enable it to maintain the state of being hooked on the left side frame 300.

[0048] In some embodiments, the second hook 512 is connected to the first hook 511, and the second hook 512 and the first hook 511 are integrally formed. This can reduce the number of parts, simplify the installation process, facilitate the forming of the second hook 512 and the first hook 511, and also strengthen the connection strength between the second hook 512 and the first hook 511.

[0049] In some embodiments, such as Figure 3 and Figure 4 As shown, the hanging part 310 can be an outwardly protruding hanging base, and the top surface of the hanging base is provided with a hanging groove, and the second hook 512 can be hooked into the hanging groove.

[0050] In some embodiments, such as Figure 1 As shown, the foldable shed also includes a top frame 600, which is rotatably connected to the rear side frame 200. When the entire shed is in use, the bottom plate 100, rear side frame 200, left side frame 300, right side frame 400, front side frame 500, and top frame 600 can be closed to form a six-sided enclosed box structure. When the entire shed is folded, the top frame 600 can be folded and stored in front of the rear side frame 200.

[0051] In some embodiments, such as Figure 7 As shown, reinforcing strips 110 are provided on both the left and right sides of the end of the base plate 100 away from the rear frame 200, which can buffer the impact received by the sides of the base plate 100 and make the sides of the base plate 100 less prone to wear.

[0052] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
