Description

Technical Field

[0001] The utility model relates to the technical field of logistics vehicles, in particular to a logistics vehicle with an extended structure. Background Art

[0002] A logistics vehicle is a unit mobile container equipment equipped with four casters for transporting and storing materials. It is often used in logistics distribution in large supermarkets or logistics turnover between factory processes. The most common one is a hand-push logistics vehicle. The existing logistics vehicles still have certain defects when in use.

[0003] In the prior art, the overall structure of the hand-pushed logistics vehicle is relatively simple. The items are directly placed on the bottom plate, and the moving wheels are moved by manually pushing the handle, so that the items can be transported in a turnover manner. Usually, the bottom plate area on the logistics vehicle is fixed, resulting in that only a certain number of items can be placed on the bottom plate, and it is difficult to place more items. If the bottom plate area of ​​the vehicle is increased blindly, it is easy to affect the passability of the cart. According to the Chinese patent application No. 202322809621.1, a logistics vehicle with an extension structure cannot adjust the overall area of ​​the bottom plate to a certain extent as needed during use. The extension plate can only be expanded or folded to a fixed area by inserting the knob into the slot. In this way, the optimal transportation area cannot be selected according to the quantity of goods. Therefore, an improved logistics vehicle with an extension structure is needed to address this problem. Utility Model Content

Fixed blocks are fixedly arranged on both sides of the lower end of the fixed vehicle plate, a screw is movably arranged between the fixed blocks through bearings, a movable block is movably screwed on one side of the surface of the screw through a thread, and a transmission rod is movably arranged on both sides of the surface of the movable block through a rotating shaft, and one end of the transmission rod close to the movable vehicle plate is movably connected to the movable vehicle plate through a rotating shaft.

[0006] Preferably, telescopic rods are fixedly provided on both sides of the lower end of the fixed vehicle plate, and the movable ends of the telescopic rods are fixedly connected to the movable vehicle plate, so that the stability of the movable vehicle plate when it moves horizontally to the left and right can be ensured by the telescopic rods.

[0007] Preferably, an extension plate is fixedly provided on the surface of the movable vehicle plate, the interior of the fixed vehicle plate is hollow, and the extension plate is movably inserted into the hollow fixed vehicle plate. Initially, the extension plate is hidden inside the fixed vehicle plate, and opens as the movable vehicle plate moves and unfolds, so that the movable vehicle plate and the fixed vehicle plate can form a complete vehicle plate.

[0008] Preferably, both sides of the lower ends of the movable vehicle plate and the fixed vehicle plate are movably provided with universal wheels, and the movable vehicle plate and the fixed vehicle plate can be conveniently moved by the universal wheels.

[0009] Preferably, a push rod is fixedly provided on the upper end of the fixed vehicle plate, and the push rod can be used to conveniently push or pull the device as a whole to move.

[0010] Preferably, a hand wheel is fixedly provided at one end of the screw rod, and the screw rod can be conveniently rotated by the hand wheel, so that the moving block can be driven to move along the screw rod under the action of the thread.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model drives the movable block to move in a direction away from the hand wheel through the screw and the thread. At this time, the movable vehicle plate can be pushed to move in a direction away from the fixed vehicle plate through the transmission rod, and the extension plate hidden inside the fixed vehicle plate can be moved out. The movement degree of the movable vehicle plate is different according to the rotation degree of the screw, so that the opening degree of the movable vehicle plate can be controlled according to the needs, so that the cargo area of ​​the vehicle plate can adapt to the cargo demand.

[0013] 2. The utility model is easy to operate. It only needs to turn the hand wheel without inserting the pin to align with the slot and other operations. The operating position is on the side of the fixed vehicle plate, which is open and unobstructed, making it convenient for rotation operation, so it is easy to promote and use.
