Description

Technical Field

[0001] This utility model relates to the field of agricultural transport vehicles, and in particular to a convenient trolley for basket-shaped objects. Background Technology

[0002] Fruits and vegetables are typically placed in baskets for transportation and transfer, thus reducing crop damage and increasing turnover. However, in actual transportation, not the entire process uses large equipment (such as forklifts) for transfer; trolleys are also used for handling smaller quantities.

[0003] For example, the existing Chinese utility model patent 202021349727.8 generally includes a handle and a frame. The basket is placed on the frame and is transported using four spaced rollers. However, there is a large gap between the frame and the ground. When there are many baskets, they need to be moved one by one onto the frame, which is quite troublesome.

[0004] For example, the existing Chinese design patent 202130603132.4 mainly uses two spaced rollers to achieve transportation. When transportation is required, the rollers are placed horizontally to achieve transportation. Although the spacing is reduced, it is still not possible to put multiple baskets directly into or push them onto the frame.

[0005] Of course, forklifts are also used, but for the current transportation of agricultural products, forklifts are large in size and expensive. Utility Model Content

[0006] Based on this, the present invention provides a convenient trolley for basket-shaped objects, aiming to improve the existing trolley structure, making it simple in structure and convenient for the transfer and transportation of baskets.

[0007] To achieve the objectives of this utility model, the following technical solution is adopted:

[0008] A convenient trolley for basket-shaped items includes:

[0009] A base frame includes a guide section, a first opening, and rollers. The base frame has a guide section, a first opening at the rear end of the guide section, and multiple rollers at the bottom of the base frame.

[0010] A support frame includes a frame body, a loading slot, and a second opening. The frame body is movably loaded within a base frame guide section. The loading slot is installed on opposite sides of the frame body. The rear end of the loading slot has a second opening. The frame body and the loading slot are combined for placing basket-shaped objects.

[0011] A pull rod includes a handle, a rod body, and a drive rod. The bottom of the pull rod is pivotally connected to the base frame, and the two ends of the drive rod are pivotally connected to the support frame and the pull rod, respectively. The pull rod drives the support frame to switch between a downward moving position and an upward lifting position through the drive rod.

[0012] The locking assembly includes a locking plate, a locking pin, and a positioning rod. The locking plate is fixedly disposed on both sides of the pivot connection between the pull rod and the base frame. The locking pin is connected to the positioning rod and movably assembled inside the pull rod. A positioning groove penetrating the rod body is provided at one end of the pull rod near the handle. A guide groove is provided near the pivot connection between the pull rod and the base frame. The positioning rod slides within the positioning groove, and the locking pin slides within the guide groove. A locking groove is provided on the locking plate for engaging with the locking pin to achieve locking. The locking assembly also includes a traction spring, which is located between the locking pin and the bottom of the pull rod to pull the locking pin downwards.

[0013] In one embodiment, at least two sets of linkage rods are provided on both sides of the support frame and the base frame, and the two ends of the linkage rods are pivotally connected to the outer side wall of the support frame and the outer side wall of the base frame, respectively.

[0014] In one embodiment, the loading slot includes a set of side plates mounted on opposite sides of the frame and loading strips extending oppositely from the bottom ends of the side plates.

[0015] In one embodiment, the frame is provided with inclined guide openings at both ends of the second opening.

[0016] In one embodiment, a limiting baffle is provided at the end of the two side plates away from the second opening, thereby playing a limiting role.

[0017] In one embodiment, the locking pin and the positioning rod are fixedly connected by a traction belt.

[0018] In practical applications, the base frame is used for movement, while the support frame is used for loading and placing basket-like objects. When the support frame moves downwards, its bottom is flush with the corresponding horizontal surface (e.g., the ground, vehicle frame, etc.), allowing the basket-like object to be pushed into the loading slot through the second opening. When transportation is required, the support frame is lifted upwards by the cooperation of the pull rod and drive rod, and then locked by the locking assembly, thus lifting the basket-like object off the ground. This facilitates the transportation of basket-like objects and solves the problem of existing trolleys being too far from the horizontal surface, requiring manual lifting of goods onto the loading frame before loading. This streamlines material transfer. More convenient and efficient transportation; when loading and transporting large quantities of goods, after the pull rod lifts the support frame off the ground, the locking component can automatically lock when the positioning rod is released, avoiding the need to press down the pull rod for a long time to keep it stable off the ground; when the handle is pulled to move the support frame upward, the pulling force of the pull rod is transmitted to the support frame through the drive rod, overcoming the weight of the support frame and the goods. Under normal use, the trolley's structural design ensures that the forces between the components are balanced and transmitted when the handle is pulled to move the support frame upward, eliminating the need to step on the base frame to balance the trolley, saving more effort and improving transportation efficiency.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] like Figures 1-7 As shown, a portable trolley for basket-shaped items includes:

[0037] The base frame 10 includes a guide section 11, a first opening 12 and rollers 13. The base frame 10 is provided with a guide section 11, the rear end of the guide section 11 is provided with a first opening 12, and the bottom of the base frame 10 is provided with multiple rollers 13.

[0038] The support frame 20 includes a frame body 21, a loading slot 22 and a second opening 23. The frame body 21 is movably loaded in the base frame guide section 11. The loading slot 22 is installed on opposite sides of the frame body 21. The rear end of the loading slot 22 is provided with a second opening 23. The frame body 21 and the loading slot 22 are combined for placing basket-shaped objects.

[0039] The pull rod 30 includes a handle 31, a rod body 32, and a drive rod 33. The bottom of the pull rod 30 is pivotally connected to the base frame 10, and the two ends of the drive rod 33 are pivotally connected to the support frame 20 and the pull rod 30, respectively. The pull rod 30 drives the support frame 20 to switch between a downward moving position and an upward lifting position through the drive rod 33.

[0040] The locking assembly 40 includes a locking piece 41, a locking pin 42, and a positioning rod 43. The locking piece 41 is fixedly installed on the left and right sides of the connection between the pull rod 30 and the base frame 10. The locking pin 42 and the positioning rod 43 are connected and movably loaded inside the pull rod 30. The locking assembly 40 is used to lock and restrict the support frame 20 when it is in the upward-raised position.

[0041] Specifically, the upper part of the rod 31 can be a bent structure, a curved surface structure, a vertical structure, or a telescopic structure. Different shapes can be selected according to the actual use scenario to meet the needs of saving effort or reducing size.

[0042] At least two sets of linkage rods 24 are provided on both sides of the support frame 20 and the base frame 10. The two ends of the linkage rods 24 are pivotally connected to the outer side wall of the support frame 20 and the outer side wall of the base frame 10, respectively, thereby realizing the movable connection between the two.

[0043] In practical use, the movable connection structure can also adopt a vertical sliding structure. The tie rod 30 and the drive rod 33 are used to drive the support frame 20 to move vertically. Furthermore, the support frame 20 and the base frame 10 described in this application adopt a swing connection method. Its structure is similar to a parallelogram. Specifically, multiple sets of linkage rods 24 are set to ensure stable linkage and play the role of lever.

[0044] In one embodiment, the support frame 20 has loading slots 22 on opposite sides. Each loading slot 22 includes a set of side plates 221 installed on opposite sides of the frame 21 and loading strips 222 extending inward from the bottom ends of the side plates 221, enabling the loading of basket-shaped objects. Furthermore, the loading strips 222 are positioned between the side plates 221 or extend inward from the lower end of the side plates 221; that is, they can be either plates or load-bearing strips of a predetermined length.

[0045] In one embodiment, the frame 21 is provided with inclined guide openings 25 at both ends of the second opening 23 to facilitate the sliding of the basket-shaped object and to play a guiding role. In a preferred embodiment, when the support frame 20 moves downward, the guide openings 25 can extend out of the position of the first opening 12, which further facilitates the pushing of the basket-shaped object. Furthermore, the ends of the two side plates 221 away from the second opening 23 are provided with limiting baffles 26, which play a limiting role.

[0046] The pull rod 30 has a positioning groove 34 that passes through the rod body 32 at one end near the handle 31, and a guide groove 35 near the pivot connection between the pull rod 30 and the base frame 10. Furthermore, the positioning rod 43 is slidably installed in the positioning groove 34, and the locking pin 42 is slidably installed in the guide groove 35.

[0047] Furthermore, the locking pin 42 and the positioning rod 43 are fixedly connected by a traction belt 44. When the positioning rod 43 is pulled to slide in the positioning groove 34, the locking pin 42 also slides in the guide groove 35.

[0048] In one embodiment, the locking piece 41 is provided with a locking groove 45 for locking the locking pin 42.

[0049] The locking assembly 40 is further provided with a traction spring 46 between the locking pin 42 and the bottom of the pull rod 30, for pulling the locking pin 42 to slide downward.

[0050] Specifically, when the locking pin 42 slides to the locking groove 45, locking is completed, and the support frame 20 cannot move up or down at this time; when the positioning rod 43 is pulled, the traction belt 44 drives the locking pin 42 to slide upward in the guide groove 35, and when it moves away from the locking groove 45, unlocking is completed, and the support frame 20 can be moved up and down by pulling the pull rod 30; when the positioning rod 43 is released, the traction spring 46 drives the locking pin 42 to slide downward to the locking groove 45 or both ends of the locking groove 45, and locking is completed.

[0051] In one embodiment, when the cargo is too heavy, the downward force on the support frame 20 increases, which causes the locking pin 42 to receive a greater upward reaction force. If the friction between the locking pin 42 and the locking groove 45, the tension of the traction spring 46, etc. are insufficient to resist this upward reaction force, the locking pin 42 may slide out of the locking groove 45, resulting in disengagement. Therefore, in actual operation, a forward-bent hook 47 can be provided in front of the locking groove 45 to better lock the locking pin.

[0052] In practical applications, the base frame 10 is used for movement, and the support frame 20 is used for loading and placing basket-shaped objects. When the support frame 20 moves downward, its bottom is flush with the corresponding horizontal surface (e.g., the ground, vehicle frame, etc.), at which point the basket-shaped object can be pushed into the loading slot 22 through the second opening 23. When transportation is required, the operator must first use the locking component 40 to unlock the device, then use the pull rod 30 and drive rod 33 to lift the support frame 20 upward, and then use the locking component 40 to lock the support frame 20, thus lifting the basket-shaped object off the ground. This facilitates the transportation of basket-shaped objects and solves the problem of existing trolleys being incompatible with horizontal surfaces. The design eliminates the need for manual lifting of goods onto the loading rack when there is a distance between them, making material transfer and transportation more convenient and efficient. When loading and transporting large quantities of goods, once the pull rod 30 lifts the support frame 20 off the ground, the positioning rod 43 can be released, and the locking component 40 can automatically lock, avoiding the need to press down the pull rod 30 for a long time to keep it stable off the ground. In addition, under normal use, the trolley's structural design ensures that when the handle 31 is pulled to move the support frame 20 upward, the forces between the components are balanced and transmitted, eliminating the need to step on the base frame 10 to balance the trolley, saving more effort and improving transportation efficiency.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
