Description

Technical Field

[0001] This utility model relates to the field of cargo handling technology, specifically a portable heavy object handling support device. Background Technology

[0002] Currently, the main type of heavy-duty handling equipment on the market is fixed push-pull trolleys. If users encounter situations requiring short-distance transport of heavy objects without prior planning or when it's inconvenient to carry a trolley, it can cause significant inconvenience. Furthermore, the trolleys themselves must be moved and stored properly before and after use. The primary purpose of these trolleys is for short-distance transport of heavy items such as equipment, luggage, books, and boxed goods. Chinese Patent CN212738198U discloses a logistics trolley for easy handling of heavy objects. A first hydraulic rod extends, pushing an insertion rod to slide outwards inside a rotating sleeve and insert into the bottom of the goods. When the insertion rod reaches its limit position, the first hydraulic rod continues to extend, causing the insertion rod to rotate around the rotating sleeve. The outer end of the insertion rod rotates upwards, pushing the goods against a rotating plate. The first hydraulic rod continues to extend, and the end of the rotating plate limits the rotation of the insertion rod. When the insertion rod cannot rotate, the rotating plate rotates upwards, causing the goods to roll onto the base. When unloading is required, a second hydraulic rod extends, causing the bottom of the rotating plate to rotate upwards, and the goods roll downwards under gravity for unloading. However, the patent has the following defects in operation: due to the large area occupied by the logistics cart, there is no mechanism to reduce the area occupied by the logistics cart, making it difficult for transport personnel to carry the logistics cart. Furthermore, due to the different sizes of heavy objects, the logistics cart lacks a mechanism to adjust according to the size of the heavy objects, which means that the logistics cart can only be used for heavy objects of a single size, resulting in a limited scope of application. Utility Model Content

[0003] This utility model aims to provide a portable heavy object handling support device, mainly to solve the technical problems of existing technology that lack a mechanism to reduce the area occupied by logistics carts, making it difficult for logistics carts to be carried by transport personnel, and because the size of heavy objects varies, the logistics carts lack a mechanism to adjust according to the size of the heavy objects, resulting in the logistics carts being limited to only a single size of heavy objects and thus having a limited scope of application.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A portable heavy-duty handling support device includes a first support plate and a second support plate. The first support plate is located to the left of the second support plate. A scissor-type telescopic frame is hinged to the bottom of the first and second support plates. A limiting frame is rotatably connected to the outer side of both the first and second support plates. Manual bolts for limiting the rotation angle are provided below the two limiting frames. One end of each manual bolt is threaded to one side of the first and second support plates, respectively. A connecting gear is rotatably connected to one side of the limiting frame. Several positioning grooves are provided on one side of the connecting gear. A moving rod is slidably arranged on one side of the limiting frame near the outer side of the connecting gear. A tension spring for movement is elastically provided on the outer side of the moving rod. Several positioning blocks are fixedly connected to one end of the moving rod. Two racks mesh with the connecting gear. A limit plate is slidably arranged on one side of the two racks near the inner side of the limiting frame.

[0005] The working principle and beneficial effects of this utility model: 1. Working Principle: Two limiting frames are rotated to be perpendicular to the first and second support plates respectively. Then, two manual bolts are screwed into the first and second support plates respectively to limit and fix the rotation angle of the limiting frames. Due to the telescopic nature of the scissor-type telescopic frame, the distance between the first and second support plates can be adjusted according to the length of the load, so that the two limiting frames are located on both sides of the load in the lateral direction, thereby limiting the lateral position of the load. A connecting gear and two racks mesh to allow the distance between the two limiting plates to be adjusted according to the width of the load. Then, with the help of a tension spring, a moving rod drives several positioning blocks to be inserted into several positioning slots, thereby limiting the position of the racks and thus limiting the lateral position of the load. This restricts the load to the first and second support plates, ensuring stability during transportation.

[0006] 2. Beneficial effects: (1) The two limiting frames are rotated to the side perpendicular to the first and second support plates respectively, and the rotation angle of the limiting frames is limited and fixed by screwing the bolts into the bolt holes. The telescopic nature of the scissor-type telescopic frame makes it easy to adjust the distance between the first and second support plates according to the length of the heavy object, so that the two limiting frames are located on both sides of the horizontal side of the heavy object, thereby limiting the horizontal position of the heavy object. A connecting gear and two racks mesh to make it easy to adjust the distance between the two limiting plates according to the width of the heavy object. Then, with the help of the tension spring, it is easy to move the rod to drive several positioning blocks to insert into several positioning slots respectively, thereby limiting the position of the rack. With the help of the anti-slip pad, it is easy to limit the heavy object to the first and second support plates. Then, with the universal wheels, it is easy for the transport personnel to push the first and second support plates to move. In the initial state, the scissor-type telescopic frame is retracted, so that the first and second support plates come into contact with each other, thereby reducing the area occupied by the first and second support plates and making it easy for the user to carry.

[0007] Preferably, a set of rotating seats is fixedly connected to one side of both the first support plate and the second support plate. Each set of rotating seats has two rotating seats. A rotating block is rotatably connected inside the rotating seat. One end of each of the two limiting frames is fixedly connected to one end of each of the two sets of rotating blocks. A baffle is fixedly connected to the bottom of the rotating seat near the outside of the rotating block. Due to the support of the baffle on the rotating block, in the initial state, the two limiting frames are located on one side of the first support plate and the second support plate, respectively.

[0008] Preferably, a rotating rod is fixedly connected between adjacent rotating blocks. The outer wall of the rotating rod passes through one side of a set of rotating seats. The outer wall of the manual bolt passes through the outer wall of the rotating rod through a thread. Threaded holes are opened on one side of the first support plate and the second support plate. The two manual bolts are respectively adapted to the two threaded holes. The manual bolts are rotated into the threaded holes so that they are screwed into the threaded holes, thereby restricting and fixing the position of the rotating rod and the rotating blocks. At this time, the two limiting frames are respectively rotated to the side perpendicular to the first support plate and the second support plate.

[0009] Preferably, a support frame is fixedly connected to one side of the limiting frame near the outer wall of the connecting gear. The outer wall of the moving rod slides through both sides of the support frame. A limiting plate is fixedly connected to one end of the moving rod. One end of the tension spring is fixedly connected to one side of the support frame, and the other end is fixedly connected to one side of the limiting plate. Several positioning blocks are arranged in a circular array at equal intervals. Pulling the limiting plate outward from the limiting frame causes the limiting plate to move the moving rod on one side of the support frame. At this time, the limiting plate causes the tension spring to stretch, and the moving rod causes several positioning blocks to separate from the positioning groove, thereby releasing the restriction on the connecting gear.

[0010] Preferably, two movable slots are formed through the outer side of the limiting frame. The two movable slots are arranged symmetrically in a circular array along the outer diameter of the connecting gear. A slider passing through the movable slot is fixedly connected to one side of the rack, and one side of the limiting plate is fixedly connected to one end of the slider. Pushing the adjacent limiting plate causes the limiting plate to move the slider inside the movable slot, thereby causing the slider to move the rack longitudinally. In turn, the adjacent rack drives the connecting gear to rotate, which facilitates adjusting the distance between the two limiting plates according to the width of the load.

[0011] Preferably, anti-slip pads are adhered to the top of the first support plate, the top of the second support plate, and one side of the two limiting frames; the weight fits tightly against the anti-slip pads, making it easy to restrict the weight to the first and second support plates.

[0012] Preferably, a set of casters is installed at the bottom of both the first support plate and the second support plate, and the two sets of casters are arranged symmetrically; the casters facilitate the movement of the first support plate and the second support plate by personnel.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6As shown, the portable heavy object handling support device includes a first support plate 1 and a second support plate 2. The first support plate 1 is located to the left of the second support plate 2. A scissor-type telescopic frame 3 is hinged to the bottom of the first support plate 1 and the second support plate 2. A limiting frame 7 is rotatably connected to the outer side of both the first support plate 1 and the second support plate 2. A set of rotating seats 4 is fixedly connected to one side of both the first support plate 1 and the second support plate 2. Each set of rotating seats 4 has two seats. A rotating block 6 is rotatably connected inside the rotating seat 4. One end of each of the two limiting frames 7 is fixedly connected to one end of each of the two sets of rotating blocks 6. A baffle 5 is fixedly connected to the bottom of the rotating seat 4 near the outer side of the rotating block 6. In the initial state, due to the retraction of the scissor-type telescopic frame 3, the first support plate 1 and the second support plate 2 come into contact with each other, thereby reducing the area occupied by the first support plate 1 and the second support plate 2, making it convenient for users to carry. Due to the support of the rotating block 6 by the baffle 5, the two limiting frames 7 are located on one side of the first support plate 1 and the second support plate 2, respectively. Manual bolts 20 for limiting rotation angle are provided below the two limiting frames 7. One end of each manual bolt 20 is threaded to one side of the first support plate 1 and the second support plate 2, respectively. A rotating rod 19 is fixedly connected between adjacent rotating blocks 6. The outer wall of the rotating rod 19 passes through one side of a set of rotating seats 4. The outer wall of the manual bolt 20 passes through the outer wall of the rotating rod 19 through the thread. Threaded holes 21 are provided on one side of both the first support plate 1 and the second support plate 2. The two manual bolts 20 are respectively adapted to the two threaded holes 21. Pulling the limiting frame 7 upward at a 90-degree angle causes the limiting frame to... 7 drives the rotating block 6 to rotate inside the rotating seat 4. At the same time, the adjacent rotating block 6 drives the rotating rod 19 to rotate, thereby driving the manual bolt 20 to rotate. This makes the two manual bolts 20 aligned with the threaded holes 21 on one side of the first support plate 1 and the second support plate 2, respectively. Then, the manual bolts 20 are rotated into the threaded holes 21, so that the manual bolts 20 are screwed into the threaded holes 21. This restricts and fixes the position of the rotating rod 19 and the rotating block 6. At this time, the two limiting frames 7 are rotated to the side perpendicular to the first support plate 1 and the second support plate 2, respectively. Pulling the first support plate 1 causes the scissor-type telescopic frame 3 to extend, making it easy to adjust the distance between the first support plate 1 and the second support plate 2 according to the length of the heavy object, so that the two limiting frames 7 are located on both sides of the lateral side of the heavy object, thereby limiting the lateral position of the heavy object. A connecting gear 9 is rotatably connected to one side of the limiting frame 7. Several positioning grooves 10 are opened on one side of the connecting gear 9. A moving rod 12 is slidably arranged on one side of the limiting frame 7 near the outer side of the connecting gear 9. A tension spring 14 for movement is elastically arranged on the outer side of the moving rod 12. Several positioning blocks 15 are fixedly connected to one end of the moving rod 12. A support frame 11 is fixedly connected to one side of the limiting frame 7 near the outer wall of the connecting gear 9. The outer wall of the moving rod 12 slides through both sides of the support frame 11. A limiting plate 13 is fixedly connected to one end of the moving rod 12. One end of the tension spring 14 is fixedly connected to one side of the support frame 11, and the other end is fixedly connected to one side of the limiting plate 13. Several positioning blocks 15 are arranged in a circular array at equal intervals. Pulling the limiting plate 13 outward from the limiting frame 7 causes the limiting plate 13 to drive the moving rod 12 to move on one side of the support frame 11. At this time, the limiting plate 13 drives the tension spring 14 to stretch, and the moving rod 12 drives several positioning blocks 15 to separate from the positioning grooves 10. The connecting gear 9 meshes with two racks 16. A limit plate 18 is slidably provided on one side of the racks 16 near the inner side of the limiting frame 7. Two moving slots 8 are opened through the outer side of the limiting frame 7. The two moving slots 8 are arranged in a circular array symmetrically along the outer diameter of the connecting gear 9. A slider 17 passing through the moving slot 8 is fixedly connected to one side of the racks 16. One side of the limit plate 18 is fixedly connected to one end of the slider 17. Pushing the adjacent limit plate 18 causes the limit plate 18 to drive the slider 17 to move inside the moving slot 8. Thus, the slider 17 drives the racks 16 to move longitudinally. In this way, the adjacent racks 16 drive the connecting gear 9 to rotate. This allows the distance between the two limit plates 18 to be adjusted according to the width of the weight. When the two limit plates 18 move to the longitudinal sides of the weight, the limit plate 13 is released. Due to the reaction force of the tension spring 14, the moving rod 12 drives several positioning blocks 15 to be inserted into several positioning slots 10 respectively, thereby limiting the position of the racks 16. Thus, the two limit plates 18 limit the longitudinal sides of the weight. Anti-slip pads 22 are glued to the top of the first support plate 1, the top of the second support plate 2, and one side of the two limiting frames 7. The anti-slip pads 22 are made of rubber. A set of casters 23 is installed at the bottom of the first support plate 1 and the second support plate 2. The two sets of casters 23 are symmetrically arranged. The weight fits tightly with the anti-slip pads 22, thereby restricting the weight on the first support plate 1 and the second support plate 2. The casters 23 also facilitate the movement of the first support plate 1 and the second support plate 2 by the transport personnel.

[0017] As can be seen from the above, the specific implementation of this utility model is as follows: In the initial state, due to the support of the baffle 5 on the rotating block 6, the two limiting frames 7 are respectively located on one side of the first support plate 1 and the second support plate 2. Due to the retraction of the scissor-type telescopic frame 3, the first support plate 1 and the second support plate 2 come into contact with each other, thereby reducing the area occupied by the first support plate 1 and the second support plate 2, making it convenient for the user to carry. Pulling the limiting frame 7 upward at ninety degrees causes the limiting frame 7 to drive the rotating block 6 to rotate inside the rotating seat 4. At the same time, the adjacent rotating block 6 drives the rotating rod 19 to rotate, thereby the rotating rod 19 drives the manual bolt 20 to rotate, so that the two manual bolts 20 are respectively aligned with the threaded holes 21 on one side of the first support plate 1 and the second support plate 2. Then, the manual bolts 20 are rotated into the threaded holes 21, so that the manual bolts 20 are screwed into the threaded holes 21, thereby limiting and fixing the position of the rotating rod 19 and the rotating block 6. At this time, the two limiting frames 7 are respectively rotated to the side perpendicular to the first support plate 1 and the second support plate 2. Pulling the first support plate 1 causes its bottom caster 23 to move away from the second support plate 2. At this time, the first support plate 1 extends the scissor-type telescopic frame 3, allowing adjustment of the distance between the first and second support plates 1 and 2 according to the length of the load. This positions the two limiting frames 7 on either side of the load, thus restricting its lateral position. Pulling the limiting plate 13 outward from the limiting frame 7 causes it to move the moving rod 12 on one side of the support frame 11. The limiting plate 13 then extends the tension spring 14, and the moving rod 12 causes several positioning blocks 15 to separate from the positioning groove 10. Subsequently, it pushes the adjacent limiting plate 18, causing the limiting plate 18 to move the slider 17 inside the moving groove 8, thereby allowing the slider to... 17 drives the rack 16 to move longitudinally, thereby driving the connecting gear 9 to rotate. This allows for adjustment of the distance between the two limiting plates 18 according to the width of the load. When the two limiting plates 18 move to the longitudinal sides of the load, the limiting plate 13 is released. Due to the reaction force of the tension spring 14, the moving rod 12 drives several positioning blocks 15 to insert into several positioning slots 10, thereby limiting the position of the rack 16. Thus, the two limiting plates 18 limit the longitudinal sides of the load and work together with the load to fit tightly against several anti-slip pads 22, thereby limiting the load on the first support plate 1 and the second support plate 2. Then, the casters 23 allow the transport personnel to push the first support plate 1 and the second support plate 2 to move.

[0018] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
