A folding, multi-layered logistics trolley

Abstract

This utility model relates to a folding and storage multi-layer logistics trolley, including a support frame, with the support frames arranged opposite each other and movable relative to each other. Each support frame has a load-bearing frame that can rotate relative to it, and the load-bearing frame is multi-layered. A folding assembly is provided between the opposite support frames. When the opposite support frames move away from each other, the folding assembly is in an unfolded position, and some or all of the load-bearing frames rotate to a position perpendicular to the support frames, thus carrying goods. When the opposite support frames move closer to each other, the folding assembly is in a folded position, and the load-bearing frames rotate in the opposite direction to a position parallel to the support frames, thus folding and storing the goods. This utility model solves the technical problems of existing multi-layer trolleys that cannot be folded, resulting in large space occupation and limited usage, as well as the fixed height of each layer, which cannot meet the needs of transporting large-volume goods.

Description

Technical Field

[0001] This utility model belongs to the field of trolley technology, specifically relating to a folding, multi-layered logistics trolley for storage. Background Technology

[0002] Handcarts are man-made transport vehicles that are pushed or pulled by hand. They have advantages such as low cost, simple maintenance, convenient operation, and light weight, and are widely used in production and daily life. Most existing handcarts consist of a frame for holding goods and handles mounted on the frame for support. The multi-layered frame is generally a one-piece assembly structure, which is not easily folded, resulting in inconvenience in use and carrying, occupying a large amount of space, hindering warehousing and transportation, and limiting its application. Furthermore, the height of each layer is fixed, which cannot meet the transportation needs of large-volume goods. Utility Model Content

[0003] In response to the various shortcomings of existing technologies, a foldable multi-layer logistics trolley is proposed to solve the technical problems of existing multi-layer trolleys being unable to be folded, resulting in large space occupation and limited usage scenarios, as well as the fixed height of each layer, which cannot meet the needs of transporting large-volume goods.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A folding and storage multi-layer logistics trolley includes a support frame, the support frames being arranged opposite each other and being movable relative to each other, a load-bearing frame being arranged on the support frame and being rotatable relative to it, the load-bearing frame being configured as multi-layered, and a folding assembly being arranged between the oppositely arranged support frames.

[0006] When the opposing support frames move in a direction away from each other, the folding assembly is in an unfolded position, and part or all of the load-bearing frame rotates to a position perpendicular to the support frame, thus carrying goods; when the opposing support frames move in a direction closer to each other, the folding assembly is in a folded position, and the load-bearing frame rotates in the opposite direction to a position parallel to the support frame, thus folding and storing.

[0007] The technical solution is further configured such that the support frame includes longitudinal support rods arranged opposite each other, and transverse support rods are connected between the longitudinal support rods arranged opposite each other, and the longitudinal support rods and the transverse support rods form a frame structure.

[0008] The technical solution is further configured such that the first end of the support frame is movably connected to the longitudinal support rod, and the second end of the support frame is a free end, which can be erected above the transverse support rod to support goods.

[0009] The technical solution is further configured such that the first end of the support frame is rotatably connected to the longitudinal support rod.

[0010] The technical solution is further configured such that a rotating plate is provided on the longitudinal support rod, and a guide groove extending in the vertical direction is provided on the rotating plate, the top of the guide groove is bent toward the longitudinal support rod to form a positioning groove;

[0011] When the first end of the support frame slides downward to the bottom of the guide groove, the support frame is in a position parallel to the support frame, and the free end of the support frame is separated from the transverse support rod; when the first end of the support frame slides upward into the positioning groove, the support frame is in a position perpendicular to the support frame, and the free end of the support frame rests on the transverse support rod.

[0012] The technical solution is further configured such that a fixed frame is provided on the side of the support frame, and when the bearing frame is in a posture parallel to the support frame, the bearing frame is located between the fixed frame and the support frame.

[0013] The technical solution is further configured such that the rotating plate is provided with a first positioning hole, the support frame is provided with a second positioning hole corresponding to the first positioning hole, and the connector passes through the first positioning hole and the second positioning hole in sequence to position the load-bearing frame in a parallel posture with the support frame.

[0014] The technical solution is further configured such that the folding assembly includes a positioning plate, the positioning plate is located between the oppositely arranged support frames, and the positioning plate is rotatably connected to the oppositely arranged support frames through a first positioning connecting rod.

[0015] The technical solution is further configured such that the supporting frame includes two relatively rotatable sub-supporting frames, the sub-supporting frames are rotatably connected to the positioning plate through a second positioning connecting rod, the first end of the sub-supporting frame is rotatably connected to the longitudinal support rod, and the second end of the sub-supporting frame is a free end;

[0016] When the folding assembly is in the unfolded position, the sub-support frame is in a position perpendicular to the support frame, and the free end of the sub-support frame rests on the positioning plate; when the folding assembly is in the folded position, the sub-support frame is in a position parallel to the support frame, and the free end of the sub-support frame is separated from the positioning plate.

[0017] The technical solution is further configured such that a movable wheel is provided below the support frame, and a handrail is also provided on the support frame.

[0018] The beneficial effects of this utility model are:

[0019] When the folding assembly is in the unfolded position, the load-bearing frame perpendicular to the support frame can be used to carry goods. At the same time, the multiple load-bearing frames are independent of each other, and the number of load-bearing frames perpendicular to the support frame can be flexibly adjusted to meet the transportation needs of large-sized goods, with high flexibility. When the folding assembly is in the folded position, it can be folded and stored, reducing volume, making it easy to carry and highly versatile. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0029] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0030] According to an embodiment of this utility model, a folding, multi-layered logistics trolley for storage is provided. Please refer to [link / reference needed]. Figures 1 to 3 The system includes a support frame 100, which are arranged opposite to each other to form a support frame. The oppositely arranged support frames 100 are movable relative to each other. A load-bearing frame 200 that can rotate relative to the support frame 100 is provided on the support frame 100. The load-bearing frame 200 is configured to be multi-layered. A folding assembly 500 is provided between the oppositely arranged support frames 100.

[0031] When the opposing support frames 100 move in a direction away from each other, the folding assembly 500 is in an unfolded posture, and part or all of the load-bearing frame 200 rotates to a posture perpendicular to the support frame 100, thus carrying goods; when the opposing support frames 100 move in a direction closer to each other, the folding assembly 500 is in a folded posture, and the load-bearing frame 200 rotates in the opposite direction to a posture parallel to the support frame 100, thus folding and storing.

[0032] Furthermore, the support frame 100 is provided in two sets, and the two sets of support frames 100 can move relative to each other, including moving away from each other and moving closer to each other.

[0033] Furthermore, the support frame 200 can be configured as a frame structure or a plate structure, and it can be configured as two, three, four or even more layers. Specifically, in this embodiment, the support frame 200 is configured with three layers, namely a top support frame 201, a middle support frame 202 and a bottom support frame.

[0034] When the folding assembly 500 is in its unfolded position under the applied force of a worker, the load-bearing frame 200, perpendicular to the support frame 100, can be used to carry goods. Please refer to [link / reference]. Figure 1Because the multiple load-bearing frames 200 are independent of each other, the number of load-bearing frames 200 perpendicular to the support frame 100 can be flexibly adjusted to meet the transportation needs of large-sized goods, offering high flexibility. Specifically, all load-bearing frames 200 can be perpendicular to the support frame 100; in this case, each load-bearing frame 200 can be used to carry goods. Please refer to [link / reference]. Figure 2 Similarly, only a portion of the load-bearing frame 200 can be perpendicular to the support frame 100. In this case, that portion of the load-bearing frame 200 can be used to carry goods, while the other load-bearing frames 200 remain parallel to the support frame 100. This is suitable for transporting large-sized goods. Please refer to [link / reference]. Figure 3 When the folding component 500 is in the folded position, it can be folded for storage, reducing its size, making it easy to carry, and it is highly versatile.

[0035] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 3 The support frame 100 includes longitudinal support rods 101 arranged opposite each other, and transverse support rods 102 are connected between the longitudinal support rods 101. The longitudinal support rods 101 and the transverse support rods 102 form a frame structure.

[0036] Furthermore, the support frame 200 is positioned between two longitudinal support rods 101 in the same group, meaning that the width of the support frame 200 is less than the length of the transverse support rod 102, to avoid interference.

[0037] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 3 The first end of the support frame 200 is movably connected to the longitudinal support rod 101, and the second end of the support frame 200 is a free end, which can be erected above the transverse support rod 102 to carry goods.

[0038] Furthermore, the movable connection includes, but is not limited to, rotatable connections and sliding connections.

[0039] Furthermore, the maximum distance between the two sets of support frames 100 should be less than the length of the load-bearing frame 200, ensuring that the free end can be erected above the transverse support rod 102. At this time, the load-bearing frame 200 is perpendicular to the support frame 100 and can be used to carry goods.

[0040] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 3 The first end of the support frame 200 is rotatably connected to the longitudinal support rod 101.

[0041] Furthermore, the first end of the support frame 200 is disposed on a first connecting plate perpendicular to it, the first end of the first connecting plate is fixedly connected to the first end of the support frame 200, and the second end of the first connecting plate is rotatably connected to the longitudinal support rod 101.

[0042] Specifically, in this embodiment, the first end of the top-level support frame 201 is rotatably connected to the longitudinal support rod 101. In some other embodiments, the support frames 200 of other layers may also adopt this connection method.

[0043] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 3 ,as well as Figures 6 to 7 The longitudinal support rod 101 is provided with a rotating plate 600, and the rotating plate 600 is provided with a guide groove 601 extending in the vertical direction. The top of the guide groove 601 is bent towards the longitudinal support rod 101 to form a positioning groove 602, and the positioning groove 602 is connected to the guide groove 601.

[0044] When the first end of the support frame 200 slides downward to the bottom of the guide groove 601, the support frame 200 is in a posture parallel to the support frame 100, and the free end of the support frame 200 is separated from the transverse support rod 102; when the first end of the support frame 200 slides upward into the positioning groove 602, the support frame 200 is in a posture perpendicular to the support frame 100, and the free end of the support frame 200 rests on the transverse support rod 102.

[0045] Specifically, in this embodiment, the middle layer support frame 202 and the longitudinal support rod 101 are connected in this way. In some other embodiments, the support frames 200 of other layers may also be connected in this way.

[0046] Furthermore, a fixed frame 300 is provided on the side of the support frame 100, and the fixed frame 300 is correspondingly provided with the rotating plate 600. Specifically, the fixed frame 300 is located above the rotating plate 600.

[0047] When the support frame 200 is in a posture parallel to the support frame 100, the support frame 200 is located between the fixed frame 300 and the support frame 100. In other words, the fixed frame 300 can prevent the support frame 200 from continuing to flip away from the support frame 100, thereby improving the stability of the support frame 200 in a posture parallel to the support frame 100.

[0048] Furthermore, the rotating plate 600 is provided with a first positioning hole 603, and the support frame 100 is provided with a second positioning hole 204 corresponding to the first positioning hole 603. The connecting piece passes through the first positioning hole 603 and the second positioning hole 204 in sequence to position the bearing frame 200 which is in a parallel posture with the support frame 100.

[0049] Specifically, the first positioning hole 603 is located above the guide groove 601, and the center of the first positioning hole 603 is located on the central axis of the guide groove 601, so as to enable the bearing frame 200 to be in a posture parallel to the support frame 100.

[0050] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 5 The folding assembly 500 includes a positioning plate 501, which is located between opposing support frames 100. The positioning plate 501 is rotatably connected to the opposing support frames 100 via a first positioning connecting rod 502.

[0051] Furthermore, the bottom of the positioning plate 501 is rotatably connected to the first end of the first positioning connecting rod 502, the second end of the first positioning connecting rod 502 is rotatably connected to the first end of the second connecting plate, and the second end of the second connecting plate is fixedly connected to the longitudinal support rod 101, with the second connecting plate being perpendicular to the longitudinal support rod 101. In other words, the first positioning connecting rod 502 can rotate relative to the positioning plate 501 and the longitudinal support rod 101 respectively.

[0052] When the opposing support frame 100 moves away from each other in a direction until the first positioning connecting rod 502 and the second connecting plate are collinear, the folding assembly 500 is in an unfolded posture; when the opposing support frame 100 moves closer to each other in a direction until the first positioning connecting rod 502 and the second connecting plate are perpendicular, the folding assembly 500 is in a folded posture.

[0053] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 5 The supporting frame includes two relatively rotatable sub-supporting frames 203. The sub-supporting frames 203 are rotatably connected to the positioning plate 501 through a second positioning connecting rod 503. The first end of the sub-supporting frame 203 is rotatably connected to the longitudinal support rod 101, and the second end of the sub-supporting frame 203 is a free end.

[0054] When the folding assembly 500 is in the unfolded position, the sub-support frame 203 is in a position perpendicular to the support frame 100, and the free end of the sub-support frame 203 rests above the positioning plate 501; when the folding assembly 500 is in the folded position, the sub-support frame 203 is in a position parallel to the support frame 100, and the free end of the sub-support frame 203 is separated from the positioning plate 501.

[0055] Furthermore, a third connecting plate perpendicular to the first end of the sub-support frame 203 is provided, and the other end of the third connecting plate is rotatably connected to the longitudinal support rod 101. A second positioning connecting rod 503 is rotatably disposed on the top of the positioning plate 501, and the second positioning connecting rod 503 is fixedly connected to the sub-support frame 203.

[0056] Specifically, in this embodiment, the folding assembly 500 is located at the bottom of the support frame 100 and below the bottom support frame. Therefore, the bottom support frame includes two relatively rotatable sub-support frames 203. Since the folding assembly 500, the bottom support frame, and the support frame 100 form a stable support structure, the bottom support frame can still be used to transport goods even if the top support frame 201 and the middle support frame 202 are parallel to the support frame 100. In other embodiments, the folding assembly 500 may be located in other parts of the support frame 100, as long as the support frame 200 above it consists of two relatively rotatable sub-support frames 203.

[0057] In this embodiment of the folding, multi-layered logistics trolley, please refer to... Figures 1 to 3 The support frame 100 is provided with casters, including but not limited to outward casters. The support frame 100 is also provided with a handrail 400 for easy hand-holding by staff to move the entire device.
