Description

Technical Field

[0001] This utility model relates to the field of trolleys, and in particular to a convenient trolley for basket-shaped items. 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 design patent 202430410115.2 generally includes handles 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. Summary of the Invention

[0006] The main purpose of this utility model is to propose a convenient trolley for basket-shaped objects, aiming to improve the existing trolley structure, making it simple and convenient for the transfer and transportation of baskets.

[0007] To achieve the above objectives, this utility model proposes a convenient trolley for basket-shaped items, comprising:

[0008] The base frame has a guide section, the rear end of the guide section has a first opening, and the bottom of the base frame has multiple rollers;

[0009] A support frame, which is movably mounted on the base frame and located within a guide section, is used to place basket-shaped objects.

[0010] The upper wall of the support frame is provided with a loading groove, and the rear end of the loading groove is provided with a second opening;

[0011] A tie rod, the bottom of which is pivotally connected to the base frame, and a drive rod is provided between the tie rod and the support frame.

[0012] 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.

[0013] A locking device for locking and restricting the support frame when it is in the upward-raised position.

[0014] Preferably, the upper part of the pull rod is a bent structure, a curved surface structure, a vertical structure, or a telescopic structure.

[0015] Preferably, 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 side wall of the support frame and the side wall of the base frame, respectively.

[0016] Preferably, the support frame includes an upper frame and side plates extending downward from the inside of the upper frame, with bearing portions extending from the bottom ends of the side plates towards each other, and the bearing portions and side plates forming the loading groove.

[0017] Preferably, the supporting portion is disposed between the side plates or extends inward from the lower end of the side plate.

[0018] Preferably, the first opening and / or the second opening are provided with inclined guide openings at both ends.

[0019] Preferably, a baffle is provided between the rear parts of the two side plates.

[0020] Preferably, the front of the base frame has two spaced-apart pivot parts, and the tie rod is pivotally mounted between the two pivot parts. The upper wall of the pivot part is arc-shaped.

[0021] The locking device includes a locking pin slidably mounted on the pull rod and a locking groove located on the upper part of the pivot. When the support frame is lifted upward, the locking pin abuts against the upper wall of the pivot and slides into the locking groove.

[0022] Preferably, the pull rod is provided with a through guide groove, the locking pin is slidably installed in the guide groove, and the guide groove drives the locking pin to slide downwards with a top spring.

[0023] Preferably, the outer side of the pivot is provided with a swinging unlocking seat, and the unlocking seat is provided with a protrusion.

[0024] When the protrusion slides to the locking groove, the protrusion abuts against the locking pin, thereby unlocking the pull rod and the pivot seat;

[0025] The front end of the unlocking seat is also provided with a forward-curved hook, which is used to block or hook the outer wall of the locking pin when it is inserted into the slot.

[0026] In practical design, the base frame is used for movement and the support frame serves as a carrier to hold the basket-like object. Therefore, in actual use,

[0027] When the support frame moves downward, the bottom of the support frame is flush with the corresponding horizontal surface (such as the ground, vehicle frame, etc.), so the basket-shaped object can be pushed into the loading slot through the second opening; thus avoiding the problem of the existing trolley still having a gap with the horizontal surface, making material transfer more convenient;

[0028] When transportation is required, the support frame is lifted upwards by the cooperation of the pull rod and the drive rod, thereby realizing the transportation and transfer of basket-shaped items; the trolley has a simple structure, low cost, and small size. Attached Figure Description

[0048] like Figures 1 to 7 As shown, a convenient trolley for basket-shaped items includes:

[0049] The base frame 1 is provided with a guide section 11, the rear end of the guide section 11 is provided with a first opening 10, and the bottom of the base frame 1 is provided with multiple rollers;

[0050] Support frame 2, which is movably installed on the base frame 1 and located in the guide section 11, is used to place basket-shaped objects;

[0051] The upper wall of the support frame 2 is provided with a loading groove, and the rear end of the loading groove is provided with a second opening 20;

[0052] A pull rod 3 is pivotally connected to the base frame 1 at its bottom, and a drive rod 30 is provided between the pull rod 3 and the support frame 2.

[0053] The two ends of the drive rod 30 are pivotally connected to the support frame 2 and the pull rod 3, respectively. The pull rod 3 drives the support frame 2 to switch between a downward moving position and an upward lifting position through the drive rod 30.

[0054] A locking device is provided for locking and restricting the support frame 2 when it is in the upward-raised position.

[0055] In practical design, the base frame 1 is used for movement and operation, while the support frame 2 serves as a carrier to hold the basket-like object. Therefore, in actual use,

[0056] When the support frame 2 moves downward, the bottom of the support frame 2 is relatively flush with the corresponding horizontal surface (such as the ground, the vehicle frame, etc.), so the basket-shaped object can be pushed into the loading slot through the second opening 20; thus avoiding the problem that the existing trolley still has a gap with the horizontal surface, making material transfer more convenient;

[0057] When transportation is required, the support frame 2 is lifted upward by the cooperation of the pull rod 3 and the drive rod 30, thereby realizing the transportation and transfer of the basket-shaped object; the trolley has a simple structure, low cost, and small size.

[0058] Specifically, the upper part of the pull rod 3 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.

[0059] In this embodiment of the utility model, at least two sets of linkage rods 4 are provided on both sides of the support frame 2 and the base frame 1. The two ends of the linkage rods 4 are pivotally connected to the side wall of the support frame 2 and the side wall of the base frame 1, respectively, thereby realizing the movable connection between the two.

[0060] Of course, in the specific active connection structure, a vertical sliding structure can also be adopted. The pull rod 3 and the drive rod 30 are used to drive the positioning frame to move vertically.

[0061] The swing connection between the support frame 2 and the base frame 1 in this application is similar to the linkage of a parallelogram. Of course, multiple sets of linkage rods 4 can also be set to ensure stable linkage and act as a lever.

[0062] Specifically, the support frame 2 includes an upper frame 21 and a side plate 22 extending downward from the inside of the upper frame 21. The bottom end of the side plate 22 has a bearing portion 23 extending towards each other. The bearing portion 23 and the side plate 22 form the loading groove, thereby realizing the loading of the basket-shaped object.

[0063] In this embodiment of the utility model, the bearing part 23 is disposed between the side plates 22 or extends inward from the lower end of the side plates 22. It can be a plate or a bearing strip of a predetermined length (i.e., forming the loading groove). Of course, in actual crop transportation, it is not easy to clean the structure of the bearing plate 23.

[0064] Specifically, the upper frame 21 is provided with inclined guide openings 51 at both ends of the second opening 20, which facilitates the sliding of the basket-shaped object and plays a guiding role; in a preferred embodiment, when the support frame 2 moves downward, the guide openings 51 can extend out of the position of the first opening 10, which further facilitates the pushing of the basket-shaped object.

[0065] In this embodiment of the utility model, a baffle 52 is provided between the rear parts of the two side plates 22, which serves as a limiting device. The baffle can be provided only in a single bearing part, or it can be provided between two bearing parts (i.e., the structure of the crossbar) to improve the structural stability.

[0066] Specifically, the front of the base frame 1 is provided with two spaced-apart pivot parts 6, and the tie rod 3 is pivotally mounted between the two pivot parts 6. The upper wall of the pivot part 6 is arc-shaped.

[0067] The locking device includes a locking pin 62 slidably mounted on the pull rod 3 and a locking groove 61 located on the upper part of the pivot 6. When the support frame 2 is lifted upward, the locking pin 62 abuts against the upper wall of the pivot 6 and slides into the locking groove 61, thereby realizing the locking of the basket-shaped object during transport and facilitating the transfer of the basket-shaped object.

[0068] In this embodiment of the utility model, the pull rod 3 is provided with a through guide groove 7, and the locking pin 62 is slidably installed in the guide groove 7. The guide groove 7 drives the top spring 60 of the locking pin 62 to slide downward, thereby realizing the locking of the trolley during transportation and thus achieving stable transportation.

[0069] Specifically, the linkage rod 4, the pull rod 3, and the drive rod 30 act as levers and linkages, thus saving effort.

[0070] Specifically, the outer side of the pivot 6 is provided with a swinging unlocking seat 8, and the unlocking seat 8 is provided with a protrusion 81.

[0071] When the protrusion 81 slides to the position of the locking groove 61, the protrusion 81 abuts against the locking pin 62, thereby unlocking the pull rod 3 from the pivot seat;

[0072] The front end of the unlocking seat 8 is also provided with a forward-curved hook, which is used to block or hook the outer wall of the locking pin 62 when it is inserted into the slot.

[0073] Therefore, in this application, the locking seat is unlocked by driving the unlocking seat 8 to swing.

[0074] When the hook abuts against the upper wall of the locking pin 62, it can achieve the function of double locking.

[0075] Of course, in specific designs, a pull rope structure can also be used to move the locking pin 62 away from the locking groove 61, thereby unlocking the device.

[0076] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
