Description

Technical Field

[0001] The invention belongs to the field of outdoor products, and in particular relates to a beach transport vehicle frame. Background Art

[0002] A beach transport cart, also known as a folding cart, is a type of outdoor cargo transport tool. It is popular among the public because it can be folded and stored easily. A Chinese utility model patent with announcement number CN220518299U and patent name "A Foldable Trolley" discloses one of the most common beach trolleys on the market, including a frame, a hand pull rod arranged in front of the frame and quick-release wheels arranged at the bottom of the frame. The frame includes a foldable chassis, a front frame, a rear frame and a side frame. A detachable carriage is arranged in the frame, wherein the front frame and the rear frame are symmetrically arranged on the front and rear sides of the chassis, and the side frames are symmetrically arranged on the left and right sides of the chassis. The front frame and the rear frame respectively include two vertical left and right support rods, the quick-release wheels are installed at the lower ends of the support rods, and two X-crossed and hinged connecting rods are connected between the support rods. The side frames are in the shape of a bridge, and each set of side frames includes an I-shaped bracket located in the middle, and a pair of first diagonal rods and a pair of second diagonal rods are symmetrically hinged at the upper and lower ends of the I-shaped bracket. The hand pull rod is assembled by a handle pull rod, a universal mount and a support seat.

[0003] The above beach transport vehicle is easy to store, but due to the storage structure, the height of the frame is relatively large when it is unfolded. Specifically, the I-shaped bracket is much higher than the ground. It is only suitable for transporting items that can be placed in the compartment, and cannot transport objects whose length exceeds the compartment. In addition, when transporting items, the heavy objects need to be lifted to a higher position to flip over the I-shaped bracket and finally put into the compartment, which is more laborious. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a beach transport vehicle frame with a small frame height, capable of transporting larger objects and saving the workload when loading and unloading objects in view of the current status of the above-mentioned prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a beach transport vehicle frame includes a first end frame and a second end frame with a running mechanism, and also includes at least one first bearing unit and at least one second bearing unit for supporting transported items. The running mechanism can be wheels or a sliding sled.

[0006] The first bearing unit includes a first rod body foldably connected to the first end frame, a second rod body foldably connected to the second end frame, a first rotating shaft is arranged between the first rod body and the second rod body, a first limiting portion is arranged on the first rod body, and a second limiting portion is arranged on the second rod body, the first limiting portion and the second limiting portion are used to support each other after the frame is unfolded to prevent the first rotating shaft from continuing to rotate and sink;

[0007] The second bearing unit comprises a third rod body foldably connected to the first end frame, a fourth rod body foldably connected to the second end frame, and a second rotating shaft is arranged between the third rod body and the fourth rod body.

[0008] When the frame is unfolded, the first rod is located below the third rod, and the second rod is located below the fourth rod. When transporting items, the items are placed on the second load-bearing unit, and the first limiting portion and the second limiting portion support each other, which can prevent the first end frame and the second end frame from approaching each other and prevent the second load-bearing unit from being pressed down by the heavy object.

[0009] In a preferred embodiment, a first connecting rod is rotatably connected between the first rod and the third rod, and a four-bar linkage is formed between the first rod, the first connecting rod, the third rod and the first end frame; a second connecting rod is rotatably connected between the second rod and the fourth rod, and a four-bar linkage is also formed between the second rod, the second connecting rod, the fourth rod and the second end frame. When the frame is folded and unfolded, the first rod, the second rod, the third rod and the fourth rod can all be linked.

[0010] In a preferred solution, there are two first carrying units, which are symmetrically arranged at the same height; there are also two second carrying units, which are symmetrically arranged at the same height, which can increase the area and stability of the carried items.

[0011] In a preferred solution, a first short rod is fixedly connected between the two first bearing units, and a second short rod is connected between the two second bearing units. The first short rod can prevent shaking and twisting between the two first bearing units; the second short rod can prevent shaking and twisting between the two second bearing units.

[0012] In a preferred solution, the first short rod is fixed on the first bearing unit at two first rods and two second rods; the second short rod is fixed on the second bearing unit at two third rods and two fourth rods.

[0013] In a preferred solution, the projections of the first rod body and the third rod body on the ground do not overlap, and the projections of the second rod body and the fourth rod body on the ground do not overlap either. The staggered arrangement can increase the overall stability.

[0014] In a preferred solution, after the vehicle frame is fully unfolded, an inclined angle structure facing away from the ground is formed between the first rod body and the second rod body.

[0015] In a preferred solution, a third limiting portion is provided on the third rod body, and a fourth limiting portion is provided on the fourth rod body. The third limiting portion and the fourth limiting portion are used to support each other after the frame is unfolded to prevent the second rotating shaft from continuing to rotate and sink.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] The height of the vehicle frame is small, and the second load-bearing unit can be unfolded to be parallel to the ground.

[0018] It can transport larger items without being limited by the size of the basket.

[0019] Save the workload when loading and unloading items. You don’t need to lift the items high, you just need to move them horizontally. BRIEF DESCRIPTION OF THE DRAWINGS
