Description

Technical area

[0001] The present utility model relates to the technology of the handcart, in particular to a movable foldable handcart. State of the art

[0002] A handcart is a transport vehicle that is pushed or pulled by hand. Usually, wheels are mounted at the four corners underneath the cart's platform to allow it to be moved. Currently, there are essentially two ways to take pets outside: either with a leash or by carrying the pet. However, carrying large pets is cumbersome, and walking them is also difficult. Placing the pet on a handcart allows for the direct transport of large animals, which is significantly less strenuous and more convenient than carrying them manually.

[0003] Currently, the size and volume of the handcarts are limited when assembled and fixed in place. This design requires the user to store the handcart in a large space. Furthermore, it is difficult to move the handcart because its footprint is fixed.

[0004] Therefore, a movable, foldable handcart is being developed to solve the problems mentioned above. Content of the utility model

[0005] The purpose of this utility model is to provide a movable, foldable handcart to solve the problem posed in the prior art described above. Because of the size and volume of handcarts in their assembled and fixed state, the user requires considerable storage space. Furthermore, it is difficult to move the handcart because its usable space is fixed.

[0006] To achieve the aforementioned objective, the present utility model offers the following technical solutions. A movable, foldable handcart comprises a cart base plate and first sliding wheels, each fixedly mounted at both ends of one side on the underside of the cart base plate. A stand is fixedly mounted at both ends of the other side on the underside of the cart base plate; second sliding wheels are provided at both ends of the stand; a rear support component is fixedly mounted at both ends of one side on the top of the cart base plate; a main connecting component is movably mounted to the central portions of both sides of the outer wall of the cart base plate; and a trailing component is movably mounted on one side on the top of the rear support component.

[0007] Preferably, the rear support component comprises groove-shaped uprights and a first U-shaped round bar which is movably mounted via a pivot axis, a second U-shaped round bar which is movably mounted on sides of the inner walls of the groove-shaped uprights, and first internally threaded rods which are fixedly mounted on both sides of one side of the underside of the second U-shaped round bar.

[0008] Preferably, hinge blocks are fixedly mounted on both sides of the central part of the outer wall of the first U-shaped round bar, a third U-shaped round bar is movably mounted on sides of the hinge blocks, a second internally threaded rod is fixedly mounted on the middle of one end of the outer wall of the third U-shaped round bar, and a first hollow locking block is fixedly mounted in the middle on the top of the groove-shaped stand.

[0009] Preferably, the main connecting component comprises a push device and support devices movably mounted on both sides of the underside of the push device, right-angled blocks movably mounted on the undersides of the support devices, and inclined support rods movably mounted on sides of the tops of the right-angled blocks.

[0010] Preferably, the push device comprises a fifth U-shaped round bar and first hollow cylindrical sleeves which are fixedly mounted on both sides on the underside of the fifth U-shaped round bar, first semicircular blocks are integrally formed on the undersides of the first hollow cylindrical sleeves, and plug rods are fixedly mounted in the centers of the inner cavities of the first semicircular blocks.

[0011] Preferably, the support devices comprise long rods and second hollow cylindrical sleeves that are fixedly mounted at the ends of the long rods, corresponding semicircular blocks are fixedly mounted at the ends of the second hollow cylindrical sleeves, and annular grooves are mounted in the centers of the inner cavities of the corresponding semicircular blocks.

[0012] Preferably, the trailing component comprises a fourth U-shaped round bar and a sixth U-shaped round bar, which is movably mounted on both sides at one end of the fourth U-shaped round bar, convex blocks are movably mounted on both sides at the underside of the sixth U-shaped round bar, and a second hollow locking block is fixedly mounted in the middle at one end of the fourth U-shaped round bar.

[0013] Compared to existing technology, the advantages of the present utility model are: 1. When the handcart is not in use, the fifth U-shaped round bar is pressed forward and downward. This causes the first semicircular blocks and the corresponding semicircular blocks at the ends of the fifth U-shaped round bar to rotate, folding the long bars forward. As the long bars fold forward, they pull the flexibly mounted angled support bars with them, causing these to also tilt forward. This, in turn, causes the first and third U-shaped round bars to tilt forward. Because the trailing component is flexibly mounted on both sides of the inner wall of the third U-shaped round bar, it tilts forward along with the third U-shaped round bar. When the lower ends of the third U-shaped round bar rest on the top of the cart's base plate, the folding and storage of the handcart is complete.This makes it easier to take the folded handcart with you when it is not in use. 2. To allow a pet to exit, the T-shaped screws connected by threads inside the first threaded rod can be loosened. This allows the first hollow locking block to be removed from one end of the first threaded rod. Since both sides of one end of the second U-shaped rod are movably mounted to the ends of the inner walls of the grooved supports, the other end of the second U-shaped rod can be brought into contact with the ground. This allows the pet to exit using the second U-shaped rod, making it very convenient.

Examples of implementation

[0015] The technical solutions in the embodiments of this utility model are described clearly and completely below with reference to the figures in those embodiments. Obviously, the described embodiments represent only a part of the embodiments of this utility model and not the entirety of them. Based on the embodiments of this utility model, all other embodiments that a person skilled in the art in the field could obtain without inventive work fall within the scope of protection of this utility model.

[0016] Example 1: From Fig. Figures 1-4 show that a movable, foldable handcart comprises a base plate 1 and first sliding wheels 2, each fixedly mounted at both ends of one side on the underside of the base plate 1. A stand 3 is fixedly mounted at both ends of the other side on the underside of the base plate 1, and second sliding wheels 4 are provided at both ends of the stand 3. The arrangement of the first sliding wheels 2 and the second sliding wheels 4 enables the base plate 1 to be moved. A rear support component 5 is fixedly mounted at both ends of one side on the top of the base plate 1, a main connecting component 6 is movably mounted to the center sections of both sides of the outer wall of the base plate 1, and a trailing component 7 is movably mounted on one side on the top of the rear support component 5.

[0017] The main connecting component 6 comprises a push device 61 and support devices 62, which are movably mounted on both sides of the underside of the push device 61. Right-angled blocks 63 are movably mounted on the undersides of the support devices 62. The right-angled blocks 63 are fixedly mounted on both sides of the central portion of the outer wall of the car floor plate 1, thereby movably mounting the undersides of the support devices 62 on both sides of the central portion of the outer wall of the car floor plate 1. Inclined support rods 64 are movably mounted on the sides of the upper sides of the right-angled blocks 63, and the upper sides of the inclined support rods 64 are movably mounted on both sides of the outer wall of the third U-shaped round rod 56.

[0018] The push device 61 comprises a fifth U-shaped round bar 611 and first hollow cylindrical sleeves 612, which are fixedly mounted on both sides on the underside of the fifth U-shaped round bar 611, first semicircular blocks 613 are integrally formed on the undersides of the first hollow cylindrical sleeves 612, and plug rods 614 are fixedly mounted in the centers of the inner cavities of the first semicircular blocks 613.

[0019] The support arrangement 62 comprises long rods 621 and second hollow cylindrical sleeves 622, which are fixedly mounted at the ends of the long rods 621. Corresponding semicircular blocks 623 are fixedly mounted at the ends of the second hollow cylindrical sleeves 622, and annular grooves 624 are mounted in the centers of the inner cavities of the corresponding semicircular blocks 623. The connecting rods 614 are movably mounted in the inner cavities of the annular grooves 624 to enable the movable assembly of the first semicircular blocks 613 and the corresponding semicircular blocks 623.

[0020] The trailing component 7 comprises a fourth U-shaped round bar 71 and a sixth U-shaped round bar 72, which is movably mounted on both sides at one end of the fourth U-shaped round bar 71. Convex blocks 73 are movably mounted on both sides at the underside of the sixth U-shaped round bar 72, and a second hollow locking block 74 is fixedly mounted in the center at one end of the fourth U-shaped round bar 71. The second internally threaded rod 57 is movably mounted in the inner cavity of the second hollow locking block 74 and is secured by a screw connection in the inner cavity of the second internally threaded rod 57, thus fixing the top of the second hollow locking block 74 and simultaneously establishing the connection between the fourth U-shaped round bar 71 and the third U-shaped round bar 56.

[0021] In this embodiment: When the handcart is not in use, the fifth U-shaped round bar 611 is pressed forward and downward. This causes the first semicircular blocks 613 and the corresponding semicircular blocks 623 at the ends of the fifth U-shaped round bar 611 to rotate, so that the long bars 621 are folded forward (towards the first sliding wheels 2). As the long bars 621 fold forward, they pull the movably mounted inclined support bars 64 with them, causing these to also tilt forward. This, in turn, causes the first U-shaped round bar 52 and the third U-shaped round bar 56 to tilt forward. Since the trailing component 7 is movably mounted on both sides of the inner wall of the third U-shaped round bar 56, it tilts forward along with the third U-shaped round bar 56.When the lower ends of the third U-shaped round bar 56 rest on the top of the trolley base plate 1, the folding and storage of the handcart is complete. This makes it easier to transport the folded handcart when it is not in use.

[0022] Example 2: This example is based on an improvement of example 1. This can be seen in detail by referring to Fig. 2 to Fig.Figure 3 illustrates this. The rear support component 5 comprises groove-shaped uprights 51 and a first U-shaped round bar 52, which is movably mounted on a pivot axis. A second U-shaped round bar 53 is connected to both sides of the inner walls of the groove-shaped uprights 51 by hinged posts, and the underside of the second U-shaped round bar 53 rotates on the inner sides of the groove-shaped uprights 51. First threaded rods 54 are fixed to one side of the underside of the second U-shaped round bar 53 on both sides. The second U-shaped round bar 53 forms a slight ramp on which a pet standing on the top of the cart floor plate 1 can disembark.

[0023] Joint blocks 55 are fixedly mounted on both sides of the central part of the outer wall of the first U-shaped round bar 52. A third U-shaped round bar 56 is movably mounted on the sides of the joint blocks 55. A second internally threaded rod 57 is fixedly mounted at the center of one end of the outer wall of the third U-shaped round bar 56. A first hollow locking block 58 is fixedly mounted in the center of the top of the groove-shaped supports 51. The first internally threaded rods 54 are movably mounted in the inner cavity of the first hollow locking block 58 and are threaded by T-shaped screws in the inner cavities of the first internally threaded rods 54, thus establishing the connection between the second U-shaped round bar 53 and the first hollow locking block 58.

[0024] In this embodiment: By placing the pet on top of the cart base plate 1, the entire handcart can be moved by moving the main connecting component 6. When a pet needs to get out, the T-shaped screws, which are threaded together in the inner cavities of the first threaded rods 54, can be loosened. This allows the first hollow locking block 58 to be removed from one end of the first threaded rod 54. Since both sides of one end of the second U-shaped round rod 53 are movably mounted to ends of the inner walls of the groove-shaped supports 51, the other end of the second U-shaped round rod 53 can be brought into contact with the ground. This allows the pet to get out at the second U-shaped round rod 53, making it very convenient to use.

[0025] Operating principle: By placing the pet on top of the cart's base plate 1, the entire handcart can be moved by moving the main connecting component 6. To allow the pet to exit, the T-shaped screws, which are threaded together in the inner cavities of the first threaded rods 54, can be loosened. This allows the first hollow locking block 58 to be removed from one end of the first threaded rod 54. Since both sides of one end of the second U-shaped round rod 53 are movably mounted to the ends of the inner walls of the groove-shaped supports 51, the other end of the second U-shaped round rod 53 can be brought into contact with the ground. This allows the pet to exit using the second U-shaped round rod 53. When the handcart is not in use, the fifth U-shaped round rod 611 is pushed forward and downward.This causes the first semicircular blocks 613 and the corresponding semicircular blocks 623 at the ends of the fifth U-shaped round bar 611 to rotate, so that the long bars 621 are folded forward (towards the first sliding wheels 2). As the long bars 621 are folded forward, they pull the movably mounted inclined support bars 64 with them, causing these to also tilt forward. This, in turn, causes the inclined support bars 64 to tilt the first U-shaped round bar 52 and the third U-shaped round bar 56 forward. Since the trailing component 7 is movably mounted on both sides of the inner wall of the third U-shaped round bar 56, it tilts forward along with the third U-shaped round bar 56. When the lower ends of the third U-shaped round bar 56 rest on the top of the cart base plate 1, the folding and storage of the handcart is complete.

[0026] The second hollow cylindrical sleeves 622, the corresponding semicircular blocks 623, the annular grooves 624, the first hollow cylindrical sleeves 612, the first semicircular blocks 613 and the connecting rods 614 together form a large locking joint, and the model number of the large locking joint is HP-716.

[0027] The contents, which are not described in detail in this description, are among the devices generally known to the experts.

[0028] Although the present utility model has been described in detail with reference to the preceding embodiments, those skilled in the art may further modify the technical solutions described in the preceding embodiments or replace some technical features with equivalent substitutions. All modifications, equivalent substitutions, improvements, etc., which are within the spirit and principles of the present utility model, should be included in the scope of protection of the present utility model.
