Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics trolley technology, and in particular to a logistics trolley for cargo transfer. Background Technology
[0002] Cargo transfer trolleys used in logistics transportation are hand-pushed and pulled vehicles, also known as handcarts. These trolleys are typically used to transport small, lightweight goods, reducing transportation difficulty, making it easier to transport goods, and preventing them from tripping during transport.
[0003] The aforementioned device lacks a structure for auxiliary clamping and securing the bottom of the goods on the transfer cart during use. This makes it easy for the existing transfer cart to tip over when the goods on it are high or piled up high and loose, due to the shaking of the goods during the start-up, stopping, or bumping of the cart. This makes it inconvenient to use.
[0004] According to Chinese Patent Publication No. CN221393606U, a cargo transfer trolley for logistics transportation is proposed. By unfolding and folding the handle, rotating it clockwise causes the threaded rod to rotate accordingly. At this time, the threaded slider, which is slidably connected in the slide groove, moves backward under the action of the rotating threaded rod, causing the slide frame and movable clamping plate to move backward until they reach the edge. Then, the cargo to be transferred is placed on top of the trolley body, and the folding handle and threaded rod are rotated counterclockwise. The rotating threaded rod causes the threaded slider to move towards the fixed clamping plate, and the slide frame and movable clamping plate at the top of the threaded slider also move towards the fixed clamping plate. At this time, the movable clamping plate is opened vertically to contact the limiting block and maintain a perpendicular state to the trolley body until the movable clamping plate moves to the inside and contacts the cargo. The movable clamping plate and the fixed clamping plate simultaneously clamp and fix the cargo. This device facilitates the clamping and fixing of the cargo to be transferred.
[0005] When this application document is used, it can only clamp and fix the goods on both sides, but the other two sides of the goods are not fixed. During the transportation of goods, there is still a possibility that the goods will tip over. Therefore, a logistics trolley for cargo transfer is proposed to solve the above problems.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] like Figure 1-6 As shown, the present invention proposes a logistics trolley for cargo transfer, including a base plate 1, a movable clamping plate 2 slidably connected to the top of the base plate 1, an adjustment mechanism 3 provided at the bottom of the base plate 1, the adjustment mechanism 3 being connected to the movable clamping plate 2 and used to drive the movable clamping plate 2 to move, and a side fixing mechanism 4 provided on the outer end face of the adjustment mechanism 3.
[0029] In this utility model, goods can be placed on the base plate 1, and the movable clamping plate 2 can be moved by the adjustment mechanism 3. A push handle is installed on the top right side of the base plate 1. The movable clamping plate 2 and the push handle can clamp and fix the left and right sides of the goods to prevent the goods from tipping over to the left and right sides. After clamping and fixing the left and right sides of the goods, the side fixing mechanism 4 can clamp and fix the front and back of the goods to prevent the goods from tipping over to the front or back.
[0030] In Embodiment 1, the side fixing mechanism 4 includes a connecting plate 41, a vertical plate 42, a movable component 43, a side clamping plate 44, a driving component 45, and an extension component 46. The connecting plate 41 is installed on the front of the movable clamping plate 2, the vertical plate 42 is located at the right end of the connecting plate 41, the movable component 43 is located inside the vertical plate 42 and is connected to the vertical plate 42 for adjusting the position of the vertical plate 42, the side clamping plate 44 is located on the back of the vertical plate 42, the driving component 45 is located on the front of the vertical plate 42 and is connected to the side clamping plate 44 for driving the side clamping plate 44 to move, and the extension component 46 is located on the back of the side clamping plate 44.
[0031] After the goods are clamped and fixed on the left and right sides by the movable clamping plate 2, the side clamping plate 44 will be located in front of the goods. At this time, the movable component 43 can drive the vertical plate 42 to move to the left or right. Under the action of the drive component 45, the side clamping plate 44 will move to the left or right. When the side clamping plate 44 moves to the middle of the goods, the drive component 45 can drive the side clamping plate 44 to move backward. When the back of the side clamping plate 44 abuts against the front of the goods, the front of the goods can be limited. At the same time, when the goods are too long, the extension component 46 can expand the contact area of the side clamping plate 44, making the contact of the side clamping plate 44 more stable.
[0032] There are two sets of side fixing mechanisms 4, which are symmetrically distributed on the front and back of the movable clamp 2. The two sets of side fixing mechanisms 4 can respectively abut and fix the front and back of the goods, thereby further ensuring the stability of the abutment and fixation of the goods.
[0033] In embodiment 2, the movable component 43 includes a movable groove 431, a movable plate 432, multiple limiting grooves 433, and a limiting rod 434. The movable groove 431 is located at the right end of the connecting plate 41. The movable plate 432 is slidably connected to the inside of the movable groove 431. The right side of the movable plate 432 is connected to the left side of the vertical plate 42. The multiple limiting grooves 433 are all located at the top of the movable plate 432 and are evenly distributed. The limiting rod 434 is slidably connected to the top of the connecting plate 41 and extends into the inside of the movable groove 431. The limiting rod 434 is slidably connected to the inside of the corresponding limiting groove 433.
[0034] When the side clamp 44 needs to move to the left or right, first remove the limiting rod 434 from the corresponding limiting groove 433, and then slide the moving plate 432 inside the movable groove 431. This allows the moving plate 432 to move to the left or right, thereby driving the vertical plate 42, the side clamp 44, the drive assembly 45, and the extension assembly 46 to move to the left or right, thus adjusting the position of the side clamp 44 so that it corresponds to the middle of the goods. At this time, when the limiting rod 434 is slidably connected to the corresponding limiting groove 433, the moving plate 432 can be fixed by the limiting groove 433 and the limiting rod 434, ensuring the stability of the side clamp 44 after the position adjustment.
[0035] In embodiment 3, the drive assembly 45 includes a first threaded rod 451, a handwheel 452, and two guide rods 453. The first threaded rod 451 is threadedly connected to the front of the vertical plate 42 and extends to its back. The back of the first threaded rod 451 is rotatably connected to the front of the side clamping plate 44. The handwheel 452 is installed at the front end of the first threaded rod 451. Both guide rods 453 are installed on the front of the side clamping plate 44 and extend to the front of the vertical plate 42. Both guide rods 453 are slidably connected to the vertical plate 42.
[0036] After the side clamp 44 is adjusted to the correct position, turn the handwheel 452. The handwheel 452 will drive the first threaded rod 451 to rotate. Under the action of the threaded thrust, the first threaded rod 451 will move backward while rotating. The first threaded rod 451 will drive the side clamp 44 to move backward. When the back of the side clamp 44 abuts against the front of the goods, the front of the goods can be limited. When the side clamp 44 moves, the two guide rods 453 can guide and limit the side clamp 44, preventing the side clamp 44 from rotating and ensuring the stability of the side clamp 44's movement.
[0037] In embodiment four, the extension component 46 includes two fixing slots 461 opened on the left and right sides of the side clamping plate 44. The front of both fixing slots 461 is connected to the outside. Two shafts 462 are installed inside the fixing slots 461. An extension stop bar 463 is rotatably connected to the outside of both shafts 462. The back of the extension stop bar 463 corresponds to the back of the side clamping plate 44. A handle 464 is installed on the side of the extension stop bar 463 away from the vertical plate 42.
[0038] When the cargo is too long, the handle 464 can be pulled directly to rotate the extension bar 463, so that the four extension bars 463 form an X shape. At this time, the extension bars 463 can increase the limiting area on the front of the cargo, ensuring the stability of the cargo limiting.
[0039] The friction between the shaft 462 and the extension stop 463 is relatively large, which gives the shaft 462 and the extension stop 463 a certain degree of damping, thereby ensuring the stability of the extension stop 463 when it is retracted and extended, and preventing it from rotating due to its own factors.
[0040] When expanding the contact area of the side clamp 44, the expansion needs to be carried out before the side clamp 44 contacts the goods. After the expansion, the goods are then contacted and fixed by the side clamp 44 and the four expansion bars 463.
[0041] In embodiment 5, the adjustment mechanism 3 includes two ear plates 31, a second threaded rod 32, a threaded block 33, and a throttle 34. Both ear plates 31 are installed at the bottom of the base plate 1. The second threaded rod 32 is rotatably connected to the right side of the right ear plate 31 and extends to its left side. The left end of the second threaded rod 32 is rotatably connected to the right side of the left ear plate 31. The threaded block 33 is threaded to the outside of the second threaded rod 32 and extends to the top of the base plate 1. The top of the threaded block 33 is connected to the bottom of the movable clamping plate 2. The throttle 34 is installed at the right end of the second threaded rod 32.
[0042] When it is necessary to use the movable clamp 2 to abut and fix the left and right sides of the goods, turn the handle 34. The handle 34 will drive the second threaded rod 32 to rotate. Under the action of the threaded thrust, the second threaded rod 32 will drive the threaded block 33 to move to the left or right. The threaded block 33 will drive the movable clamp 2 to move to the left or right. Thus, under the action of the handle, the goods are clamped and fixed by the movable clamp 2.
[0043] In embodiment six, two guide blocks are installed at the bottom of the movable clamping plate 2, and two guide grooves are opened at the top of the base plate 1. The two guide blocks are slidably connected inside the two guide grooves respectively. The movable clamping plate 2 can be guided by the guide blocks and guide grooves to ensure the stability of the movable clamping plate 2 during movement.
[0044] In Example 7, casters are installed at the four corners of the bottom of the base plate 1, and the logistics cart can be moved by the four casters and the push handle.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
