[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, an embodiment of the present invention proposes: a logistics trolley with expandable storage space, including a vehicle plate 1, an expansion plate 2 and a placement frame 3. The expansion plate 2 is slidably placed on the upper part of the vehicle plate 1, so as to form a plate body that can be slid and adjusted on the vehicle plate 1. During use, the expansion plate 2 is unfolded to expand the storage space of the trolley for storing logistics goods, which is convenient for transporting more goods at one time and improving the scope of application. The placement groove 204 opened on the upper part of the expansion plate 2 is provided with a slidable and rotatable baffle 203, which is convenient for forming a pair of expansion plates 2 at the edge position. The components for blocking logistics goods prevent the goods from falling during the movement of the trolley and ensure stable use. A support rod 303 is slidably installed on the slide rail 301 of the mounting frame 3 at the lower part of the vehicle plate 1. The middle part of the support rod 303 is integrally bent and fixedly connected to the side plate 201 integrally provided at the edge of the vehicle plate 1 of the expansion plate 2. The support rod 303 is used to stably connect the expansion plate 2 to the slide rail 301, so that the expansion plate 2 can be stably debugged. At the same time, after the expansion plate 2 is unfolded, it also provides effective support for the expansion plate 2 to ensure stable use.

[0024] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the side of the expansion plate 2 facing away from the side plate 201 is fixedly connected with a connecting hook 202, and the connecting hook 202 is slidably connected to the edge of the vehicle plate 1, thereby improving the sliding stability of the expansion plate 2 on the vehicle plate 1, so that the expansion plate 2 can slide and unfold smoothly on the vehicle plate 1, thereby increasing the storage space for logistics goods and facilitating the transportation of more logistics goods at one time. At the same time, a limiting member is placed on the connecting hook 202 located on the side of the push handle 102, and the limiting member is rotatably connected to the connecting hook 202, and the movable end contacts the vehicle plate 1, thereby fixing the expansion plate 2 on the vehicle plate 1, improving the stability of the expansion plate 2 during use, and ensuring stability. The baffle 203 is provided with sliding grooves on both sides of the placement groove 204, and the sliders at the corresponding positions on both sides of the baffle 203 are slidably connected to the sliding grooves. The cooperation between the two is used to improve the stability of the baffle 203 debugging, which is convenient for blocking logistics goods during use. When the logistics goods need to be blocked, the logistics goods are ensured to be stably stored. During the expansion process, the baffle 203 is directly pushed by hand to slide toward the outside of the expansion plate 2 in the placement groove 204. When it slides to the outermost position, the baffle 203 is rotated to make it perpendicular to the expansion plate 2. The baffle 203 is provided with rope through-holes distributed at equal intervals, which is convenient for fixing the rope for tying logistics goods to the baffle 203, thereby improving the convenience of use.

[0025] The rubber anti-skid bumps fixedly embedded at the edges of both sides of the baffle 203 abut against the edges of the placement groove 204, ensuring that the baffle 203 does not slide in the placement groove 204 when the hand does not push the baffle 203, so that the baffle 203 can be stably stored and used.

[0026] like Figure 1 and Figure 3 As shown, in some embodiments, both ends of the slide rail 301 are fixedly connected to the lower part of the vehicle plate 1 through the mounting seat 302, and the slide rail 301 is stably installed. A track for the support rod 303 to slide back and forth and adjust is formed at the lower part of the vehicle plate 1, so as to realize smooth sliding debugging of the support rod 303, and the sliding sleeve 3031 fixedly connected at both ends of the support rod 303 is slidably connected to the slide rail 301 at the corresponding position, so that the support rod 303 is stably connected to the slide rail 301, ensuring that the support rod 303 can slide smoothly on the slide rail 301, thereby improving the stability during the debugging process. The middle part of the support rod 303 is bent and formed to form a connecting portion 3032, and the connecting portion 3032 is fixedly connected to the side plate 201 of the expansion plate 2, so that the support rod 303 can be stably connected to the expansion plate 2, so that the expansion plate 2 can slide on the vehicle plate 1 together during the movement of the support rod 303, and unfold to both sides, thereby expanding the storage surface of the logistics goods on the trolley, facilitating the storage of more logistics goods, and expanding the scope of application.

[0027] like Figure 1 As shown, in some embodiments, universal wheels 103 are fixedly connected to the four corners of the lower part of the vehicle plate 1, and a brake mechanism is installed on the universal wheel 103. The universal wheel 103 and the brake mechanism thereon are both existing technologies, so they are not described in detail. The vehicle for transporting logistics goods can be smoothly moved on the ground during use, which improves the convenience of use. After moving to the designated position, the universal wheel 103 is limited by the brake mechanism to achieve stable use.

[0028] A push handle 102 is mounted on a connector 101 fixedly connected to one side of the upper portion of the vehicle plate 1. The push handle 102 is rotatably connected to the connector 101, so that the push handle 102 can be stably connected to the vehicle plate 1. During movement, the push handle 102 can be directly grasped by hand to push or pull the vehicle on the ground to achieve smooth movement of the vehicle. At the same time, for the sake of comfort in use, a rubber protective cover can be installed on the hand-holding part of the push handle 102 to improve comfort during use.

[0029] When the trolley is in use, the goods to be transported are directly placed on the expansion plate 2 on the upper part of the trolley plate, and then the push handle 102 is held by hand to pull or push the trolley on the ground to move to the designated position. When the goods are stored, the universal wheels 103 are limited and fixed by the brake mechanism, which makes it convenient to store the goods on the trolley. When the trolley is moved, the limit of the universal wheels 103 by the brake mechanism can be cancelled.

[0030] When the area for storing goods on the trolley is insufficient, the limiting piece on the connecting hook 202 is pressed to cancel the limiting fixation of the expansion plate 2, and then the expansion plate 2 is pushed to slide on the vehicle plate 1. During this process, the support rod 303 moves along with the expansion plate 2, and the support rod 303 slides on the slide rail 301. After the expansion plate 2 is adjusted to the specified position, the pressing of the limiting piece is cancelled so that the limiting piece contacts the vehicle plate 1, and the expansion plate 2 is stably and effectively limited and fixed, so that the expansion plate 2 is fixed in the adjusted position for stable use. Then, the goods can be stored on the adjusted trolley.

[0031] During the storage of goods, if the goods need to be blocked and limited, you only need to push the baffle 203 by hand to slide in the placement groove 204, and after sliding to the outermost end, rotate the baffle 203 vertically on the expansion plate 2. When the goods are stacked too high or unstable, you can use a tying rope to tie the goods to the trolley, and tie the end of the rope to the rope perforation on the baffle 203 to prevent the goods from falling during the movement of the trolley, thereby improving the stability of cargo transportation.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
