Description

Technical Field

[0001] This utility model relates to the field of logistics trolley technology, specifically a logistics trolley with anti-tipping function. Background Technology

[0002] Warehouse and logistics trolleys are suitable for small warehouse turnover, temporary goods transfer in shopping malls and shops, and unloading and turnover of less-than-truckload (LTL) goods. Material trolleys and warehouse-specific trolleys are made of high-quality stainless steel or steel, with solid plate frame welding, and have strong load-bearing capacity.

[0003] Chinese patent publication number "CN208544293U" discloses "a logistics trolley, wherein a placement structure is fixedly connected to the front and back of the bottom right side of the top plate, a tray is fixedly connected to the bottom of the placement structure, a rotating structure is movably connected to the bottom of the tray, anti-tipping structures are fixedly connected to both sides of the front of the rotating structure, a push-pull structure is fixedly connected to the middle of the bottom of the back of the rotating structure, a first lead screw is movably connected to the bottom of the first support rod, a second lead screw is movably connected to the bottom of the third support rod, threaded sleeves are threadedly connected to the middle of the outer sides of the first and second lead screws, a placement plate is fixedly connected to the right side of the threaded sleeve, and sliding sleeves are fixedly connected to the front and back of the left and right sides of the back of the placement plate." This patent, by setting up a crank rod and a support plate, makes the logistics trolley more convenient to use. In the above-mentioned design, workers are positioned on the handle side, behind the logistics cart. When the cart tilts, the base drives the crank and support plate in a circular motion as the cart tilts forward. After the cart tilts to a certain angle, the bottom of the support plate contacts the ground. At this point, the support plate and crank work together to support the cart and prevent it from tilting further, effectively preventing the goods from tipping over. This gives the cart an anti-tipping advantage. However, while the aforementioned patent uses a crank and support plate to support the cart and prevent it from tipping over, it does not actually secure the goods themselves. This allows the goods to easily shift within the placement frame, potentially causing them to tip over and become damaged. Therefore, we propose a logistics cart with an anti-tipping function. Utility Model Content

[0004] The purpose of this utility model is to provide a logistics trolley with anti-tipping function to solve the problem proposed in the background art. However, the above-mentioned patents support the trolley by setting up curved rods and support plates to prevent the trolley from tipping over. In actual use, however, they cannot fix the goods themselves, making the goods easy to flip over in the placement frame, which in turn makes the goods easy to tip over in the placement frame and cause damage to the goods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a logistics trolley with anti-tipping function, comprising a base and a placement frame, wherein the placement frame is fixedly connected to the top of the base, and the inner cavity of the placement frame has a strip-shaped groove on its front and rear side walls, a slider is slidably connected to the inner cavity of the strip-shaped groove, a partition is fixedly connected between the inner side walls of the slider, a screw is fixedly connected to the front and rear side walls of the slider, and a locking cap is screwed onto the outer side wall of the screw.

[0006] As a further description of the above technical solution:

[0007] The base has grooves on the left and right side walls of its inner cavity, and a first spring is fixedly connected to the top and bottom of the inner cavity of the groove.

[0008] As a further description of the above technical solution:

[0009] The inner cavity of the first spring is fitted with a first damping rod, and the end of the first spring is fixedly connected to a first movable block.

[0010] As a further description of the above technical solution:

[0011] An installation plate is fixedly connected between the inner sidewalls of the first movable block, and a movable wheel is fixedly connected to the four bottom corners of the installation plate.

[0012] As a further description of the above technical solution:

[0013] A handle is fixedly connected to the right side wall of the base, and a frame is fixedly connected to the top of the inner cavity of the base.

[0014] As a further description of the above technical solution:

[0015] The inner cavity of the frame is fixedly connected to the left and right side walls with a second spring, the inner cavity of the second spring is fitted with a second damping rod, and the end of the second spring is fixedly connected to a second movable block.

[0016] As a further description of the above technical solution:

[0017] The bottom of the second movable block is rotatably connected to a connecting rod, and the end of the connecting rod is rotatably connected to the top left and right sides of the mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This logistics trolley with anti-tipping function allows the slider to slide in the strip groove by loosening the locking cap. Then, the goods are placed in the placement frame, and the partition is slid to make the partition stick tightly to the goods. Then, the locking cap is tightened to fix the partition, thereby clamping the goods and preventing them from tipping over during transportation. This device can individually fix the goods and prevent them from tipping over during transportation.

[0020] 2. This logistics trolley with anti-tipping function generates vibration during transportation, which is transmitted to the first spring. The first spring, in conjunction with the first damping rod, provides initial shock absorption. Then, the mounting plate moves the connecting rod during vibration, causing the end of the connecting rod to move the second movable block. This causes the second movable block to push and pull the second spring, which, in turn, works with the second damping rod to provide further shock absorption. Finally, through this double shock absorption, the device can be more stable during logistics transportation, thus preventing collisions during transport and improving the efficiency of cargo transportation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] This utility model provides a logistics trolley with an anti-tipping function, which can individually secure goods to prevent them from tipping over during transport. It also provides shock absorption during transport to prevent collisions, thus improving the efficiency of goods transportation. Please refer to [link / reference]. Figure 1-5 It includes a base 100 and a placement frame 200;

[0031] Please see Figure 1-3The base 100 has grooves 110 on its left and right sidewalls. A first spring 120 is fixedly connected to the top and bottom of the inner cavity of the groove 110. A first damping rod 121 is sleeved in the inner cavity of the first spring 120. A first movable block 130 is fixedly connected to the end of the first spring 120. A mounting plate 140 is fixedly connected between the inner sidewalls of the first movable block 130. A movable wheel 150 is fixedly connected to the four corners of the bottom of the mounting plate 140. A handle 160 is fixedly connected to the right sidewall of the base 100. A frame 170 is fixedly connected to the top of the inner cavity of the base 100. A second spring 180 is fixedly connected to the left and right sidewalls of the inner cavity of the frame 170. A second damping rod 181 is sleeved in the inner cavity of the second spring 180. The end of the second spring 180 is fixedly connected to the handle 160. A second movable block 190 is connected, and a connecting rod 191 is rotatably connected to the bottom of the second movable block 190. The end of the connecting rod 191 is rotatably connected to the top left and right sides of the mounting plate 140. When the device vibrates during transportation, the vibration is transmitted to the first spring 120, which then works with the first damping rod 121 to perform initial shock absorption. When the device vibrates, the mounting plate 140 drives the connecting rod 191 to move, which in turn drives the second movable block 190 to move. This causes the second movable block 190 to push and pull the second spring 180, which then works with the second damping rod 181 to perform shock absorption again. Finally, through double shock absorption, the device can be more stable during logistics transportation.

[0032] In summary, this device enables shock absorption during cargo transportation, preventing collisions and improving the efficiency of cargo transport.

[0033] Please see Figure 1 , Figure 2 , Figure 4 and Figure 4 The placement frame 200 is fixedly connected to the top of the base 100. The front and rear side walls of the inner cavity of the placement frame 200 are provided with strip grooves 210. A slider 220 is slidably connected to the inner cavity of the strip groove 210. A partition 230 is fixedly connected between the inner side walls of the slider 220. A screw 240 is fixedly connected to the front and rear side walls of the slider 220. A locking cap 250 is screwed onto the outer side wall of the screw 240. By loosening the locking cap 250, the slider 220 can slide in the strip groove 210. Then, by placing the goods into the placement frame 200 and sliding the partition 230, the partition 230 is pressed tightly against the goods. Then, by tightening the locking cap 250, the partition 230 is fixed, thereby clamping the goods with the partition 230, so that the goods can be prevented from tipping over during transportation.

[0034] In summary, this allows the device to individually secure goods, preventing them from tipping over during transport.

[0035] In practical use, those skilled in the art first loosen the locking cap 250 to slide the partition 230 to a suitable position. Then, by placing the goods between the partitions 230 of the placement frame 200 and sliding the partitions 230 until they are firmly against the goods, the locking cap 250 is tightened to secure the partitions 230, thus clamping the goods. Subsequently, the drive device is moved by pushing or pulling the handle 160. During transportation, when the moving wheels 150 pass over bumpy sections of road, the vibration generated by the moving wheels 150 will be transmitted to the mounting plate 140. The mounting plate 140 transmits some of the vibration to the first movable block 130, causing the first spring 120 to work with the first damping rod 121 to perform initial shock absorption. At the same time, the mounting plate 140 also transmits another part of the vibration to the second movable block 190 through the connecting rod 191, which in turn causes the second movable block 190 to push and pull the second spring 180, so that the second spring 180 works with the second damping rod 181 to perform shock absorption again, thus keeping the device stable during transportation. Finally, when the device is moved to the unloading location, the locking cap 250 is loosened again, allowing the partition 230 to slide away from the side of the goods, and the goods can be removed.
