Description

Technical Field

[0001] The utility model relates to the technical field of carts, in particular to a novel folding cart. Background Art

[0002] A cargo trolley is a handcart used for carrying and transporting items. It usually consists of a platform, a handle and four wheels. This type of cart can be used to carry lightweight cargo such as boxes, parcels, luggage, tools and other small items. They are widely used in various occasions, including warehouses, shops, offices, postal services and homes.

[0003] The existing Chinese utility model patent entitled "A Folding Cargo Trolley" was published on February 9, 2024, with the announcement number CN220465594U. A U-shaped handle rod is provided at one end of the vehicle plate, and two self-folding moving wheel mechanisms are symmetrically provided on the lower surface of the vehicle plate near both sides, and a control mechanism hinged to the U-shaped handle rod is provided on the lower surface of the vehicle plate near the two self-folding moving wheel mechanisms. When the U-shaped handle rod is folded, the self-folding moving wheel mechanism can be folded and rotated through the cooperation of the control mechanism and the self-folding moving wheel mechanism, so that the U-shaped handle rod and the self-folding moving wheel mechanism are folded and fit onto the surface of the vehicle plate, thereby reducing the overall volume of the cargo trolley, reducing the space required to be occupied, and facilitating storage and placement.

[0004] However, this cart has certain defects when in use: the length of the U-shaped handle bar and the length of the cart plate are not adjustable. To ensure that the U-shaped handle bar can be completely placed in the cart plate, the length of the cart plate needs to be greater than the length of the U-shaped handle bar. In order to facilitate the grasping of the U-shaped handle bar by hand, the length of the U-shaped handle bar itself has a certain specification. Therefore, even after the U-shaped handle bar is stored in the cart plate, its overall floor space is still relatively large. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a new folding cart to solve the problem that the length of the U-shaped handle bar and the vehicle board of the existing folding cart cannot be adjusted, and even after the U-shaped handle bar is folded and placed on the vehicle board, the overall floor space is still large.

A first fixing hole is provided on the first bracket, a third fixing hole is provided on the second bracket, and at least one fourth fixing hole is provided on the vertical plate. When the first bracket and the second bracket are stably fixed and are in an upper and lower stacked state, the third fixing hole and the fourth fixing hole are opposite, and the first locking piece is located in the third fixing hole and the fourth fixing hole. When the push-pull frame is in use, the first fixing hole and the fourth fixing hole are opposite, and the first locking piece is located in the first fixing hole and the fourth fixing hole.

When the first spring positioning bead protrudes from the outer surface of the first insertion rod, the distance between the first spring positioning bead and the side of the outer wall of the first insertion rod facing away from it and the diameter of the first pull ring are both greater than the diameter of the fourth fixing hole.

[0010] Preferably, the telescopic cargo carrier includes a first base, a second base and an extension rod, at least two extension rods are fixedly installed on the side of the second base facing the first base, slots adapted to the extension rods are opened on the side of the first base facing the second base, at least one first positioning hole is opened on both sides of the first base along the length direction of the extension rod, at least two second positioning holes are opened on one side of the extension rod along its length direction, a third locking piece is provided on the telescopic cargo carrier, the third locking piece is located in the first positioning hole and the second positioning hole, and the length of each of the brackets is not greater than the length of the telescopic cargo carrier in the retracted state.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0023] like Figures 1-6 As shown, the utility model provides a novel folding cart, comprising a telescopic carrier 1 and a push-pull frame 2, the telescopic carrier 1 having a retracted state and an extended state, one end of the push-pull frame 2 being hinged to one end of the telescopic carrier 1, the folding cart further comprising a first locking mechanism for fixing the push-pull frame 2 in a horizontal folded state and a use state (the use state of the push-pull frame 2 is a state in which the push-pull frame 2 is tilted or perpendicular to the telescopic carrier 1, and here the push-pull frame 2 is taken as an example to be perpendicular to the telescopic carrier 1), the push-pull frame 2 comprises at least two brackets (the brackets herein all adopt a frame plate structure, and a plurality of support rods are further provided in the middle of the frame plate), two adjacent brackets having an upper and lower stacked state and a flat state, and a second locking mechanism for stably fixing the two brackets in the flat state is provided between the two adjacent brackets (that is, the horizontal folded state of the push-pull frame 2 herein includes at least one upper and lower stacked state);

[0024] When the cart is not in use, adjust the telescopic loading frame 1 to the retracted state, then adjust the first locking mechanism so that it no longer fixes the push-pull frame 2 in the use state, adjust the push-pull frame 2 to the horizontally folded state, and then adjust the second locking mechanism so that it no longer stably fixes at least two brackets in the flat state, stack the two adjacent brackets so that they are in an up and down stacked state (that is, the push-pull frame 2 is in the horizontally folded state), and then use the first locking mechanism to lock and fix the horizontal folded state of the push-pull frame 2, thereby avoiding the problem that the U-shaped handle rod and the vehicle plate of the existing cart cannot be adjusted. Even after the U-shaped handle rod is folded and placed on the vehicle plate, its overall footprint is still large, further reducing the footprint of the cart.

[0025] like Figure 1-Figure 5 As shown, the first locking mechanism includes a vertical plate 3 and a first locking member 4, the push-pull frame 2 includes a first bracket 21 and a second bracket 22, two vertical plates 3 are fixedly installed on one side of the top surface of the telescopic loading rack 1, and the first bracket 21 is hinged between the two vertical plates 3. A first fixing hole 211 is provided on the first bracket 21, and a third fixing hole 222 is provided on the second bracket 22. At least one fourth fixing hole 31 is provided on the vertical plate 3. When the first bracket 21 and the second bracket 22 are stably fixed and are in an upper and lower stacked state, the third fixing hole 222 and the fourth fixing hole 31 are opposite, and the first locking member 4 is located in the third fixing hole 222 and the fourth fixing hole 31. When the push-pull frame 2 is in use, the first fixing hole 211 and the fourth fixing hole 31 are opposite, and the first locking member 4 is located in the first fixing hole 211 and the fourth fixing hole 31;

[0026] It should be noted that when a plurality of fourth fixing holes 31 are provided on the riser 3, a plurality of fourth fixing holes 31 are provided on the circumference of the riser 3 with the hinge point between the first bracket 21 and the riser 3 as the center. When the push-pull frame 2 is tilted at different angles, the first locking member 4 can fix the push-pull frame 2 at different positions, making it convenient for different people to push and pull the stroller at a comfortable angle.

[0027] Here, the push-pull frame 2 includes two brackets (a first bracket 21 and a second bracket 22) and a fourth fixing hole 31 is provided on the vertical plate 3 as an example for description:

[0028] When the cart is not in use, first adjust the telescopic carrier 1 to the retracted state (such as Figure 2As shown), fold the push-pull frame 2 and stack the first bracket 21 and the second bracket 22: first, take out the first locking member 4 located in the first fixing hole 211 and the fourth fixing hole 31, so that the push-pull frame 2 is no longer positioned and fixed, rotate the push-pull frame 2 so that it is flat on the top surface of the telescopic carrier 1, and the first bracket 21 and the second bracket 22 are in a flat state, then adjust the second locking mechanism so that the first bracket 21 and the second bracket 22 are no longer stably fixed in the flat state, and adjust the second bracket 22 so that it is stacked on the first bracket 21, so that they are in an up and down stacked state (as shown). Figure 2 and Figure 5 As shown), the third fixing hole 222 and the fourth fixing hole 31 are aligned, and the first locking member 4 is inserted and fixed in the third fixing hole 222 and the fourth fixing hole 31, so that the first bracket 21 and the second bracket 22 are stably fixed in an upper and lower stacking state (as shown). Figure 2 The problem that the length of the U-shaped handle bar and the vehicle board of the existing cart cannot be adjusted is avoided. Even after the U-shaped handle bar is folded and placed on the vehicle board, the overall floor space occupied is still large, thereby further reducing the floor space occupied by the cart.

[0029] On the contrary, when the cart needs to be used, the first locking member 4 is removed from the third fixing hole 222 and the fourth fixing hole 31, and the second bracket 22 is adjusted to move from above the first bracket 21 to be flush with the first bracket 21, and then the second locking mechanism is adjusted to stably fix the first bracket 21 and the second bracket 22 in a flat state, and then the push-pull frame 2 is rotated until the first fixing hole 211 and the fourth fixing hole 31 are aligned, and then the first locking member 4 is inserted into the first fixing hole 211 and the fourth fixing hole 31, so that the first bracket 21 and the second bracket 22 are stably fixed in the use state (such as Figure 1 shown);

[0030] It should be noted that when the push-pull frame 2 is in the free tilt adjustment state, the first locking member 4 will not be inserted into the first fixing hole 211 and the fourth fixing hole 31. At the same time, in order to prevent the first locking member 4 from being lost, the first locking member 4 is inserted into the third fixing hole 222 for storage.

[0031] like Figure 1-Figure 5As shown, the second locking mechanism includes an L-shaped plate 5 and a second locking member 7. The first bracket 21 is symmetrically fixed with two L-shaped plates 5 near one end of the second bracket 22. The L-shaped plate 5 includes a horizontal portion and a vertical portion. The vertical portion is provided with a sliding groove 51 along a direction perpendicular to the top surface of the horizontal portion, and a fifth fixing hole 52 is provided on the horizontal portion. A limiting rod 6 is fixedly installed at one end of the second bracket 22, and the limiting rod 6 is movably arranged in the sliding groove 51. A second fixing hole 221 is provided on the second bracket 22. When the push-pull frame 2 is in use, the second fixing hole 221 and the fifth fixing hole 52 are opposite to each other, and the second locking member 7 is located in the second fixing hole 221 and the fifth fixing hole 52. When the push-pull frame 2 is in the horizontal folded state, the second bracket 22 is located above the first bracket 21, and the second locking member 7 is located in the first fixing hole 211. The length of each bracket is not greater than the length of the telescopic carrier 1 in the retracted state, ensuring that the bracket will not extend out of the telescopic carrier 1, and preventing the telescopic carrier 1 from being extended and easily tripping people.

[0032] Here, the first bracket 21 and the second bracket 22 are provided in segments, rather than being hingedly provided and then fixed together on the L-shaped plate 5. Therefore, when a section of the first bracket 21 or the second bracket 22 is damaged, it can be replaced separately.

[0033] Specifically, when the second bracket 22 needs to be stacked on top of the first bracket 21, the second locking member 7 is removed from the second fixing hole 221 and the fifth fixing hole 52, so that the second bracket 22 is no longer fixed. At this time, the second bracket 22 is pulled upward, thereby driving the limiting rod 6 to move upward in the slide groove 51, and then the second bracket 22 is rotated forward around the limiting rod 6 until the second bracket 22 is stacked on top of the first bracket 21. Then, the first locking member 4 is inserted and fixed in the third fixing hole 222 and the fourth fixing hole 31, so that the first bracket 21 and the second bracket 22 are stably fixed in the upper and lower stacking state;

[0034] On the contrary, when it is necessary to adjust the first bracket 21 and the second bracket 22 to be in a flat state, the first locking member 4 is removed from the third fixing hole 222 and the fourth fixing hole 31, and the second bracket 22 is rotated in the opposite direction around the limiting rod 6 until the second fixing hole 221 is located directly above the fifth fixing hole 52. The second bracket 22 is then adjusted to move downward until the first bracket 21 and the second bracket 22 are in a flat state, and the first locking member 4 is then inserted into the second fixing hole 221 and the fifth fixing hole 52, thereby completing the locking and fixing of the second bracket 22, so that the first bracket 21 and the second bracket 22 are stably in the flat state.

[0035] It should be noted that the second locking member 7 here can be set as a hand-tightening bolt (the second fixing hole 221 and the fifth fixing hole 52 here are threaded holes adapted thereto) or have the same structure as the first locking member 4.

[0036] like Figure 3 and Figure 5 As shown, the first locking member 4 includes a first insertion rod 41, a first spring positioning bead 42 and a first pull ring 43. The first pull ring 43 is fixedly installed at one end of the first insertion rod 41, and a first spring positioning bead 42 is provided on the outer wall of the other end of the first insertion rod 41. The distance between the first spring positioning bead 42 and the first pull ring 43 is not less than the distance between the two vertical plates 3. When the first spring positioning bead 42 protrudes from the outer surface of the first insertion rod 41, the distance between the first spring positioning bead 42 and the side of the outer wall of the first insertion rod 41 facing away from it and the diameter of the first pull ring 43 are both larger than the diameter of the fourth fixing hole 31.

[0037] By providing the first pull ring 43, it is convenient to draw out the first insertion rod 41 and play a certain limiting role. In cooperation with the first spring positioning bead 42, the first insertion rod 41 will not easily move out of the fourth fixing hole 31 and the third fixing hole 222 when it passes through the fourth fixing hole 31 of the two vertical plates 3. On the contrary, when the first locking member 4 needs to be removed later, the first pull ring 43 is pulled to drive the first insertion rod 41 to move away from the push-pull frame 2. Due to the effect of the first spring positioning bead 42, when the first pull ring 43 is pulled hard to drive the first insertion rod 41 to move, the first insertion rod 41 will be separated from the fourth fixing hole 31 and the third fixing hole 222.

[0038] It should be noted that the first insertion rod 41 can also be set as two, each of which passes through a vertical plate 3 and a side rod of the second bracket 22. The specific principle is not repeated here.

[0039] In addition, when the cart is not in use, the second locking member 7 can be placed in the first fixing hole 211 (eg Figure 5 As shown, when the second locking member 7 is a hand-tightened bolt, the first fixing hole 211 is set as a threaded hole), which can effectively prevent the second locking member 7 from being lost after being taken out from the second fixing hole 221 and the fifth fixing hole 52.

[0040] like Figure 1 and Figure 6 As shown, the telescopic cargo carrier 1 includes a first base 11, a second base 12 and an extension rod 13. At least two extension rods 13 are fixedly installed on the side of the second base 12 facing the first base 11. A slot adapted to the extension rod 13 is opened on the side of the first base 11 facing the second base 12. At least one first positioning hole 111 is opened on both sides of the first base 11 along the length direction of the extension rod 13. At least two second positioning holes 131 are opened on one side of the extension rod 13 along its length direction (here taking two second positioning holes 131 as an example, one is farthest from the second base 12 and the other is closest to the second base 12). A third locking member 8 is provided on the telescopic cargo carrier 1, and the third locking member 8 is located in the first positioning hole 111 and the second positioning hole 131;

[0041] The third locking member 8 here can adopt the same structure as the first locking member 4, and can also adopt the same structure as the second locking member 7. Here, the third locking member 8 including the second insertion rod 81, the second spring positioning bead 82 and the second pull ring 83 is used as an example for description. The specific locking principle of the third locking member 8 is not detailed here.

[0042] When the cart is not in use and the telescopic carrier 1 needs to be adjusted to the retracted state, the second pull ring 83 is held by hand to drive the second insertion rod 81 to move, so that the second insertion rod 81 is disengaged from the first positioning hole 111 and the second positioning hole 131. At this time, the second base 12 is pushed closer to the first base 11 and moves until the extension rod 13 is completely inserted into the slot of the first base 11. At this time, the first positioning hole 111 is aligned with the second positioning hole 131 closest to the second base 12. Then, the second insertion rod 81 is aligned with the first positioning hole 111 and inserted through the second positioning hole 131, so that the telescopic carrier 1 is stably in the retracted state and occupies the smallest area when not in use.

[0043] When the cart needs to be used, that is, the telescopic cargo carrier 1 is adjusted to the extended state, the second insertion rod 81 is pulled out to disengage from the first positioning hole 111 and the second positioning hole 131 closest to the second base 12, and then the second base 12 is pulled to move away from the first base 11, thereby driving the extension rod 13 to gradually move out of the slot until the first positioning hole 111 is aligned with the second positioning hole 131 farthest from the second base 12, and then the second insertion rod 81 is adjusted to be inserted into the first positioning hole 111 and the second positioning hole 131 farthest from the second base 12, so that the telescopic cargo carrier 1 is stably in the extended state, thereby facilitating the adjustment of the cart to place more goods.

[0044] like Figure 1 and Figure 2 As shown, a handle 9 is detachably fixedly mounted on the other end of the push-pull frame 2, and the handle 9 can be held by hand to make it more convenient to push and pull the cart.

[0045] like Figure 1 and Figure 2 As shown, the bottom surface of the telescopic carrier 1 is provided with a universal wheel 10 with a brake pad, which facilitates the control of the cart's movement or stillness.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
