DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] like Figure 1-4 As shown, a folding cart that can be used as a bed comprises a base frame 13, and a front support frame 24 and a rear support frame 22 are hinged at the front and rear ends of the base frame 13 respectively. A front connecting frame 25 is fixedly connected to the front supporting frame 24, and a sliding rod 6 is fixedly connected to the front supporting frame 24. A supporting pull rod 11 is hinged to the top end of the front connecting frame 25, and the end of the supporting pull rod 11 is slidably connected to the sliding rod 6. A locking member detachably connected to the front connecting frame 25 is provided on the sliding rod 6. Preferably, the locking member is a buckle 8, and the buckle 8 is snap-fitted with the front connecting frame 25. A rear end of the base frame 13 is hinged to a rear connecting frame 20, and a locking rod 21 is hinged to the top end of the rear connecting frame 20, and an end of the locking rod 21 is hinged to the rear supporting frame 22. When in normal use, a cloth surface 5 is laid on each bracket.

[0026] The front and rear ends of the base frame 13 are respectively hinged with a front supporting side rod 2 and a rear supporting side rod 3, one end of the front supporting side rod 2 is hinged to the front end of the base frame 13, and the other end is hinged to the rear supporting side rod 3, one end of the rear supporting side rod 3 is hinged to the rear end of the base frame 13, and one end is hinged to the supporting pull rod 11, and a lock 27 is provided between the rear supporting side rod 3 and the rear connecting frame 20. The triangular structure formed by the front supporting side rod 2, the rear supporting side rod 3 and the base frame 13 makes the overall structure of the cart more stable when the cart is loaded with items and moves, reducing the risk of items falling out of the cart when the cart is fully loaded and pulled.

[0027] like Figure 4As shown, the base frame 13 includes a front plate 131 and a rear plate 132. The front plate 131 and the rear plate 132 are hinged at the middle part of the base frame 13. When folding, the front plate 131 and the rear plate 132 can be folded by applying force upward from the hinge.

[0028] A connecting piece 18 is provided at the hinge of the front supporting side rod 2 and the rear supporting side rod 3, and the bottom end of the connecting piece 18 is detachably connected to the hinge of the front plate 131 and the rear plate 132. When the cart needs to be folded and stored, the bottom end of the connecting piece 18 is removed from the hinge of the front plate 131 and the rear plate 132. After removal, the front plate 131 and the rear plate 132 are folded by applying force upward at the hinge. After the front plate 131 and the rear plate 132 are folded, the rear support frame 22 and the front support frame 24 are retracted toward the direction of the front plate 131 and the rear plate 132 to complete the folding of the cart.

[0029] The top end of the front connecting frame 25 is hinged with a support cross bar 12 and a support pull rod 11, and the other end of the support cross bar 12 is hinged with the end of the rear support side bar 3.

[0030] The other end of the support pull rod 11 is hinged with a slider 7, which is mounted on the slide bar 6 and can move on the slide bar 6. When the cart is in a lying position, the buckle 8 on the slide bar 6 is released from the front connecting frame 25, and the slider 7 moves from the slide bar 6 to the buckle 8 set at the bottom of the slide bar 6.

[0031] An armrest 1 is provided at the top of the slide bar 6, and the armrest 1 is rotatably connected to the slide bar 6 to meet the needs of customers of different body shapes to drag and pull the cart.

[0032] A connecting seat 19 is provided at the rear end of the base frame 13 , the rear supporting side rod 3 and the rear supporting frame 22 are hinged at the upper end of the connecting seat 19 , and the supporting bottom rod 4 and the rear connecting frame 20 are hinged at the lower end of the connecting seat 19 .

[0033] A square hole 17 is provided in the middle portion of the connecting seat 19, a rear straight rod 16 is arranged between the square holes 17 of the connecting seats 19 on both sides, two roller seats 10 are welded to the rear straight rod 16, roller seats 10 are provided with rollers 15 for controlling the steering of the cart during movement, and a front straight rod 23 is arranged between the front connecting frames 25, the front straight rod 23 is welded to the front connecting frames 25, a universal wheel seat 9 is arranged at the welding point, the universal wheel seat 9 is provided with a universal wheel 14, and the universal wheel 14 is used to determine the linear motion direction of the cart.

[0034] The universal wheel seat 9 and the roller seat 10 are provided with brakes 26. When the cart needs to be fixed in position, the brakes 26 are opened to fix the universal wheels 14 and the rollers 15, and the cart is unfolded into a lying bed state to lie down and rest to prevent the cart from moving.

[0035] The universal wheels 14 and the rollers 15 are arranged in a staggered manner. When the cart is in a folded state, the rollers 15 and the universal wheels 14 are in a side-by-side state, thereby reducing the space occupied by the cart after folding.

[0036] To summarize, when the cart changes from the unfolded state to the lying bed state, the front end of the cart first releases the latch 8 from the front connecting frame 25. After the latch is released, the front supporting frame 24 rotates and tilts to allow the slider 7 to move on the slide bar 6. When the slider 7 is restricted by the supporting pull rod 11 and cannot move, the front supporting frame 24 rotates and tilts to the maximum angle. When the rear supporting frame 22 is opened, the locking rod 21 is pulled to unlock the locking rod 21. The rear connecting frame 20 and the rear supporting frame 22 are folded downward at the same time and gradually opened from the fitted state. The cart is in the lying bed state. At this time, the locking rod 21 is against the ground and used as a supporting frame.

[0037] The folding cart that can be used as a bed provided by the utility model is introduced above. The principle and implementation method of the utility model are described in this article using specific examples. The description of the above embodiments is only used to help understand the utility model and its core idea. It should be pointed out that for ordinary technicians in this technical field, the utility model can also be improved and modified without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
