[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution:

[0024] A trolley for logistics warehousing includes a base plate 1, a connecting frame 7 fixedly connected to the outer side of the base plate 1, a slider 18 slidably connected inside the connecting frame 7, a spring 17 between the slider 18 and the connecting frame 7, locking blocks 15 fixedly connected at equal intervals on one side of the slider 18, an adjusting plate 8 slidably connected inside the base plate 1, and limiting slots 19 equidistantly opened inside the adjusting plate 8 to cooperate with the locking blocks 15, symmetrically mounted casters 9 on the bottom of the base plate 1 and the bottom of the adjusting plate 8, fixed blocks 4 symmetrically fixedly connected to the outer side of the base plate 1, a rotating shaft 6 rotatably connected between the two fixed blocks 4, a protective frame 5 fixedly connected to the outer side of the rotating shaft 6, and connecting blocks 12 fixedly connected at equal intervals to the outer side of the adjusting plate 8. A connecting frame 10 is rotatably connected between the two, and the connecting frame 10 is slidably connected to the protective frame 5. During the transfer of goods in logistics warehousing, the goods can be placed by the base plate 1. The length of the adjusting plate 8 extending out of the base plate 1 can be adjusted by sliding the adjusting plate 8 along the base plate 1, which facilitates the adjustment of the length of the trolley during use and enhances the applicability of the device. The spring 17 can drive the slider 18 to move and reset. The slider 18 drives the locking block 15 to move, so that the locking block 15 moves into the interior of the limit slot 19, thereby locking the position of the adjusting plate 8. The rotating shaft 6 drives the protective frame 5 to rotate, and the protective frame 5 drives the connecting frame 10 to rotate, thereby preventing it from affecting the loading and unloading of goods.

[0025] Furthermore, the adjusting plate 8 is in contact with the inner wall of the base plate 1. By the contact between the adjusting plate 8 and the inner wall of the base plate 1, the movement of the adjusting plate 8 can be limited to prevent it from shifting during movement.

[0026] Furthermore, a connecting rod 16 is fixedly connected to one side of the slider 18. The connecting rod 16 is slidably connected to the connecting frame 7. A handle is fixedly connected to the end of the connecting rod 16 away from the slider 18. The handle drives the connecting rod 16 to move, and the connecting rod 16 drives the slider 18 to move.

[0027] Furthermore, a worm gear 14 is fixedly connected to the outer side of the rotating shaft 6, and a fixing frame 11 is fixedly connected to the outer side of one of the fixing blocks 4. A worm 13 that works with the worm gear 14 is rotatably connected inside the fixing frame 11. The worm 13 drives the worm gear 14 to rotate, and the worm gear 14 drives the rotating shaft 6 to rotate.

[0028] Furthermore, a knob is fixedly connected to one end of the worm gear 13. The outer side of the knob is provided with anti-slip texture. The anti-slip texture can increase friction and facilitate the rotation of the knob, which drives the worm gear 13 to rotate.

[0029] Furthermore, telescopic rods 3 are fixedly connected at equal intervals to the top of the base plate 1. One end of the telescopic rod 3 is fixedly connected to a push rod 2. The push rod 2 facilitates the pushing of the device. When the height of the push rod 2 needs to be adjusted, the bolts on the outside of the telescopic rod 3 are loosened to adjust the height of the push rod 2. After adjustment, the bolts on the outside of the telescopic rod 3 are tightened to lock the height. The operation is convenient.

[0030] Working principle:

[0031] In use, during the transfer of goods in logistics warehousing, the base plate 1 allows for the placement of goods. When the goods are long, pulling the handle at one end of the connecting rod 16 causes the slider 18 to move, compressing the spring 17. The slider 18 then moves the locking block 15 away from the limit slot 19, releasing the locking state of the adjusting plate 8. This allows the adjusting plate 8 to be pulled and slid along the base plate 1, adjusting the length of the adjusting plate 8 extending beyond the base plate 1, thus facilitating the adjustment of the trolley's length during use. This enhances the applicability of the device. After adjustment, releasing the handle at one end of the connecting rod 16 will cause the spring 17 to move and reset the slider 18 due to its elasticity. The slider 18 then moves the locking block 15 into the corresponding limit slot 19, thereby locking the position of the adjusting plate 8. The operation is convenient. When loading and unloading goods, the worm gear 13 can be rotated. The worm gear 13 drives the rotating shaft 6 to rotate through the worm wheel 14. The rotating shaft 6 drives the protective frame 5 to rotate, and the protective frame 5 drives the connecting frame 10 to rotate, thereby preventing it from affecting the loading and unloading of goods and making it easy to use.
