Logistics is a system that controls raw materials, finished products, finished products and information. It is the physical movement from supply to the transfer and ownership of various intermediate links to the final consumer, so as to achieve the clear goals of the organization. Modern logistics is a product of economic globalization and an important service industry that promotes economic globalization.
[0003] The national patent publication number is: CN214648374U, which discloses a portable logistics box. The application states: "There are some disadvantages in the logistics boxes that are currently used more frequently. When transporting goods, the logistics box is too large to be convenient to carry, and it is too small to hold more items. The volume of the logistics box cannot be changed according to needs, and it cannot be well adjusted when transporting items, and cannot meet the needs of use." Although the application solves this problem, it has the following defects:
[0004] When the logistics box is in use, the height of the internal box is adjusted to increase the overall capacity. When loading items, the overall width cannot be increased, resulting in limitations in the overall loading. In addition, a logistics box that is too high is not convenient for adding items inside. At the same time, a large space will be left on the top of the expanded logistics box, which cannot be used. Utility Model Content

[0007] The extension mechanism includes an extension frame, which is slidably connected to the right side of the logistics box. The same load-bearing block is provided on the opposite side of the logistics box and the extension frame. The left and right sides of the load-bearing block are rotatably connected to rollers through bearings. A first extension cover is provided on the top of the logistics box, and a second extension cover is slidably connected to the top of the first extension cover.
[0008] Preferably, the logistics box and the inner bottom of the extension frame are both provided with evenly distributed limiting grooves, and the limiting grooves correspond to the rollers.

[0012] Preferably, a second iron block is fixedly connected to the top of the first extension cover, and second magnets are fixedly connected to the left and right sides of the bottom of the second extension cover.
[0013] Preferably, the first extension cover and the second extension cover are both fixedly connected to the inner top with a second magnet, and the left and right sides of the bottom of the limiting block are both fixedly connected to the first iron block.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The portable logistics box drives the load-bearing block inside the logistics box to move by sliding the extension frame to the right, so that the protruding part of the bottom of the load-bearing block slides down and engages with the space formed between the logistics box and the extension frame. At the same time, the second extension cover moves to the right inside the first extension cover as the extension frame moves, and can completely cover the top of the logistics box and the extension frame. The laterally expanded logistics box and the lowered load-bearing block increase the length and height of the storage space inside the portable logistics box, which is convenient for placing items of different sizes and solves the problem of the overall height of the portable logistics box when adding items to the portable logistics box.
[0016] 2. The portable logistics box utilizes the magnetic attraction between the first iron block and the first magnet, so that the first iron block drives the limit block to slide down to the inner bottom after the second extension cover is unfolded, thereby fixing the two portable logistics boxes stacked up and down to each other. When the portable logistics box is expanded, the first iron block can be magnetically attracted to the second magnet to increase stability, thereby solving the problem that the top of the portable logistics box cannot be used.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 5 In an embodiment of the utility model, a portable logistics box includes a logistics box 1, an inner wall of the logistics box 1 is slidably connected to an extension mechanism 2, a fixing mechanism 3 is provided at the bottom of the extension mechanism 2, and the logistics box 1 and the bottom of the extension mechanism 2 are fixedly connected with evenly distributed support legs 4.
[0025] The extension mechanism 2 includes an extension frame 201, which is slidably connected to the right side of the logistics box 1. The same load-bearing block 204 is provided on the opposite side of the logistics box 1 and the extension frame 201. The left and right sides of the load-bearing block 204 are rotatably connected to rollers 205 through bearings. A first extension cover 202 is provided on the top of the logistics box 1. The second extension cover 203 is slidably connected to the top of the first extension cover 202. The rollers 205 are provided to reduce the friction between the bottom of the load-bearing block 204 and the top of the logistics box 1 and the extension frame 201, so that the extension frame 201 can be quickly pulled out of the logistics frame 1 after heavy objects are placed on the top of the load-bearing block 204.
[0026] See also Figure 4The logistics box 1 and the extension frame 201 are both provided with evenly distributed limit grooves 210 at the bottom, and the limit grooves 210 correspond to the rollers 205. The limit grooves 210 are used to limit the rollers 205 corresponding to the box, so that the rollers 205 can be limited after the load-bearing block 204 is moved.
[0027] See also Figure 4 and Figure 5 The logistics box 1 and the extension frame 201 are both provided with evenly distributed slide grooves 209 at the bottom, and the slide grooves 209 are slidably connected with sliders 208. When the sliders 208 slide to the edge of the slide grooves 209, they can drive the movable block 207 to rotate, so as to clamp the protruding part of the bottom of the load-bearing block 204.
[0028] See also Figure 4 The bottom of the load-bearing block 204 is provided with evenly distributed fixed grooves 206, and the fixed grooves 206 are rotatably connected with movable blocks 207 through bearings, and the inner diameter of the movable block 207 is rotatably connected to the outer diameter of the slider 208 through bearings. As the movable block 207 is pulled by both ends, the two ends of the movable block 207 can rotate with the movement of the load-bearing block 204 and turn from a vertical direction to a balanced direction.
[0029] See also Figure 4 The fixing mechanism 3 includes a limit block 301, which is slidably connected to the inner wall of the load-bearing block 204. A uniformly distributed tension spring 302 is fixedly connected between the top of the limit block 301 and the top of the load-bearing block 204. As the tension spring 302 pulls, the limit block 301 can be controlled to return to its original position, so that the bottom of the limit block 301 is flush with the bottom of the logistics box 1.
[0030] See also Figure 2 and Figure 3 A second iron block 306 is fixedly connected to the top of the first extension cover 202, and second magnets 305 are fixedly connected to the left and right sides of the bottom of the second extension cover 203. The second magnet 305 is adsorbed on the second iron block 306 to fix the position of the second extension cover 203, and at the same time, it is convenient to pull the second extension cover 203 to the right.
[0031] See also Figure 3 and Figure 4 The first extension cover 202 and the second extension cover 203 are both fixedly connected with the second magnet 305 at the top, and the left and right sides of the bottom of the limit block 301 are both fixedly connected with the first iron block 303. The first iron block 303 is magnetically attracted by the second magnet 305, so that the limit block 301 moves downward into the groove between the first extension cover 202 and the second extension cover 203.
[0032] The working principle of the utility model is:
[0033] The box cover composed of the first extension cover 202 and the second extension cover 203 is removed, and according to the transportation requirements, the extension frame 201 can be pulled to expand the logistics box 1 as a whole. As the extension frame 201 slides out of the logistics box 1 to the right, as the extension frame 201 moves, the rollers 205 roll in the limit grooves 210, so that when the slider 208 slides to the edge in the slide groove 209, the movable block 207 is rotated and moves through the bearings at both ends, so that the bottom of the load-bearing block 204 contacts the top of the logistics box 1 and the extension frame 201 respectively, and the second extension cover 203 can be pulled to the right to increase the box cover to a suitable size. When the logistics boxes 1 are stacked, the first iron block 303 at the bottom of the load-bearing block 204 placed on the top is attracted by the first magnet 304 at the top of the second extension cover 203 at the bottom, so that the limit block 301 slides downward and engages with the mounting groove formed by the first extension cover 202 and the second extension cover 203. When there is no need to expand the logistics box 1, the first iron block 303 arranged in the logistics box 1 placed on the top and the second magnet 305 on the first extension cover 202 and the second extension cover 203 at the bottom attract each other to achieve a fixing effect. When there are no logistics boxes 1 stacked up and down, the tension spring 302 pulls the limit block 301 and the first iron block 303 back to their original positions.
