Description
Technical Field
[0001] This utility model relates to the field of logistics trolley technology, specifically to a multi-layer logistics trolley. Background Technology
[0002] In the logistics and transportation sector, traditional logistics trolleys typically use a simple stacking method to place goods. Workers stack the workpieces to be transferred layer by layer onto the trolley before transporting them. However, this transfer method has the following problems:
[0003] When it is necessary to retrieve the bottom layer of goods, there are usually two methods: 1) The upper layer of goods must be moved away one by one before the bottom layer of goods can be retrieved, which is cumbersome and labor-intensive; 2) The bottom layer of goods can be directly pulled out, but this can easily cause the upper layer of goods to tip over due to uneven force, which poses a safety hazard.
[0004] To address the aforementioned issues, existing technologies, such as patent CN221023721U, propose a multi-layer logistics transfer trolley, including a fixed shelf, a movable shelf, and a supporting structure. By adjusting the height of the movable shelf, goods can be stored in layers, facilitating the retrieval of goods of different sizes. However, this solution still has the following shortcomings;
[0005] Because there are no protective structures around the trolley, when there are bumps or sudden stops along the transfer route, the layered goods lack lateral restraint and are prone to slipping off the side of the trolley, causing damage to the goods. This poses a significant safety hazard, especially for small or fragile items. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a multi-layer logistics cart, which solves the problems mentioned in the background section.

[0034] Example
[0035] To address the technical problems in the background section, a multi-layer logistics trolley is proposed as follows:
[0036] Combination Figures 1-7 As shown, this utility model provides a multi-layer logistics trolley, including a base plate 100, a guardrail assembly 200 installed on the top surface of the base plate 100, material storage components 300 installed at equal intervals in the middle of the guardrail assembly 200, casters 400 installed on the bottom surface of the base plate 100, a handle 500 fixedly connected to one side of the base plate 100, and an anti-slip component 600 installed in the middle of one side of the base plate 100; the guardrail assembly 200 includes a post 201, a protective net 202, and guardrail components, and the top surface of the base plate 100 has four... The base plate 100 is fixedly connected to four sets of four columns 201. One side of each column 201 has a T-slot 203, and the other side of each column 201 has an equal number of adjustment holes 204. The inner cavity of the adjustment hole 204 is connected to the T-slot 203. Protective nets 202 are installed at both ends of the top surface of the base plate 100. The two ends of the protective nets 202 are fixedly connected to the columns 201. Guardrail components are installed at the other two ends of the top surface of the base plate 100. The two ends of the guardrail components are connected to the columns 201.
[0037] A guardrail assembly 200 can be formed by two sets of protective nets 202 and two sets of guardrail components, thereby intercepting the items on the storage plate 301 and preventing the items from falling off the storage plate 301 during the transfer process.
[0038] In this embodiment, the guardrail component includes a first folding door and a second folding door. The first folding door and the second folding door are respectively installed at the other two ends of the top surface of the base plate 100. A plug block 205 is fixedly connected to one side of the first folding door. A plug hole 206 is provided on the top surface of the plug block 205. A sliding sleeve 207 is fixedly connected to one side of the second folding door. A sliding post 208 is slidably connected inside the sliding sleeve 207. An L-shaped rod 209 is fixedly connected to one side of the sliding post 208. One end of the L-shaped rod 209 is inserted into the plug hole 206.
[0039] By cooperating with the insert block 205, the insertion hole 206, the sliding sleeve 207, the sliding column 208 and the L-shaped column 209, the first folding door and the second folding door can be fixed together, preventing the goods from falling off the storage rack during transportation.
[0040] In this embodiment, the first folding door includes a first vertical rod 210. One side of the column 201 is rotatably connected to the first vertical rod 210 via a hinge. One side of the first vertical rod 210 is rotatably connected to a first folding rod 211 via pins at equal intervals. One end of the first folding rod 211 is rotatably connected to a second folding rod 212 via a pin. One end of the second folding rod 212 is rotatably connected to a second vertical rod 213 via a pin. The second folding door adopts the same structure as the first folding door.
[0041] By cooperating with the first folding rod 211 and the second folding rod 212, the first folding door and the second folding door can be folded and stored, thereby reducing the space occupied by the first folding door and the second folding door when they are rotated open.
[0042] In this embodiment, the material storage assembly 300 includes a storage plate 301, and T-shaped blocks 302 are fixedly connected to the four sides of the storage plate 301. The T-shaped blocks 302 slide within the T-shaped groove 203, and locking components are installed around the bottom surface of the storage plate 301.
[0043] The storage plate 300 enables the storage of items. The four sets of T-blocks 302 allow the storage plate 301 to slide between the four sets of columns 201, which facilitates the adjustment of the spacing between the two sets of storage plates 301 later.
[0044] In this embodiment, the locking component includes a square plate 303. The square plates 303 are fixedly connected to the bottom surface of the storage plate 301 around the perimeter. A locking pin 304 is slidably connected inside the square plate 303. One end of the locking pin 304 is inserted into the adjustment hole 204. The other end of the locking pin 304 is fixedly connected to a pull plate 305. A reset damping rod 306 is fixedly connected to one side of the pull plate 305 and between the square plates 303.
[0045] Through the cooperation of locking post 304, pull plate 305, reset damping rod 306 and square plate 303, on the one hand, the storage plate 303 is fixed between the four sets of upright posts 201, and on the other hand, it is convenient to adjust the spacing between the two sets of storage plates 303.
[0046] In this embodiment, the anti-slip assembly 600 includes an extension plate 601. The extension plate 601 is fixedly connected to one side of the base plate 100. A downward threaded rod 602 is threadedly connected to the extension plate 601. One end of the downward threaded rod 602 is rotatably connected to an anti-slip plate 603. Guide rods 604 are fixedly connected to both ends of the top surface of the anti-slip plate 603. One end of the guide rod 604 slides within the extension plate 601.
[0047] The anti-slip plate 603 moves up or down through the cooperation of the downward threaded rod 602 and the guide rod 604 in the anti-slip assembly. When the anti-slip plate 603 moves down, it will contact the ground, thus preventing the trolley from slipping when it is not in use. When the anti-slip plate 603 moves up, it is stored away, making it convenient for staff to use the trolley later.
[0048] Working principle and usage process of this utility model:
[0049] In use:
[0050] When in use, first, move the device to the area where loading is required. After it is moved to the designated position, the operator rotates the downward threaded rod 602. When the downward threaded rod 602 rotates, it will drive the anti-slip plate 603 to move downward under the action of the guide rod 604. As the anti-slip plate 603 moves downward, one side of the anti-slip plate 603 contacts the ground. At this time, under the action of the anti-slip plate 603, the material cart will slip when parked.
[0051] At this point, the staff moves the sliding column 208 upward. As the sliding column 208 moves upward, it slides within the sliding sleeve 207. As the sliding column 208 moves, one end of the L-shaped rod 209 disengages from the insertion hole 206. Once the L-shaped rod 209 is disengaged, the staff begins to fold and store the first and second folding doors. During folding, the second vertical rod 213 is moved first. As the second vertical rod 213 moves, the first and second folding rods 211 and 212 fold in a V-shape, causing the second vertical rod 213 to move closer to the first vertical rod 210. Once closer, the staff then rotates the first and second folding doors to open them, facilitating the later storage of items.
[0052] When storing items, to accommodate items of different heights, the position of the storage plate 301 on the column 201 is adjusted. To adjust, first, pull the pull plate 305. As the pull plate 305 moves, it moves the locking pins 304, simultaneously stretching the reset damping rod 306. When one end of each of the four locking pins 304 disengages from the adjustment hole 204, the worker can then use the T-block 302 to move the storage plate 301 up or down along the column 201, thus adjusting the distance between the two sets of storage plates 301. After the distance is adjusted, the worker releases the pull plate 305. The reset damping rod 306 then resets the locking pins 304. Once reset, the locking pins 304 are inserted into the corresponding adjustment holes 204, completing the height adjustment of the storage plate 301.
[0053] After adjustment, the items to be stored can be placed on the corresponding storage plate 301. After the items are placed, rotate the first folding door and the second folding door. When the first folding door and the second folding door are on the same horizontal plane, pull the first folding door and the second folding door so that the first folding door and the second folding door are close to each other. After they are close, insert one end of the L-shaped rod 209 back into the socket 206 so that the guardrail assembly 200 is sealed around, preventing the items from falling off the storage plate during the transportation of the items.
