[0016] 3. Beneficial effects:

[0017] By adopting the technical solution provided by the utility model, compared with the prior art, the logistics sorting trolley of the utility model has the following specific contents:

[0018] (1) When the express delivery needs to be sorted and transferred by the logistics trolley, the second reversing gear can be driven to rotate by the handle, and the second reversing gear drives the first reversing gear and the screw to rotate by meshing. When the screw rotates, the rectangular cover is driven to rise and fall through the threaded connection formed by the threaded connector. When taking and placing items at the bottom of the car box, the rectangular cover is moved downward to facilitate taking and placing items at the bottom of the car box. When the rectangular cover moves upward and its top exceeds the top of the car box, the volume of the logistics trolley can be increased. By setting a liftable rectangular cover, the volume of the logistics trolley can be adjusted as needed, and it is convenient to take and place items;

[0019] (2) When the rectangular cover and the carriage move relative to each other, the carriage contacts the inner wall of the rectangular cover through the ball bearings. The rolling friction between the rectangular cover and the ball bearings replaces the sliding friction between the rectangular cover and the carriage, which can effectively reduce the resistance encountered when the rectangular cover is lifted or lowered, so as to drive the rectangular cover to lift or lower and adjust the volume of the sorting cart.

[0020] (3) When the sorting trolley moves, it moves through the universal wheel. When the universal wheel is vibrated, it drives the bracket to vibrate. The bracket is connected to the base through a damping spring, which effectively reduces the vibration force transmitted to the sorting trolley by the universal wheel, avoiding the vibration of the sorting trolley when moving, which may cause collision of the items inside the trolley, so as to protect the items in the sorting trolley. The universal wheel moves relative to the base during shock absorption. The guide structure composed of the guide rod and the guide groove avoids the deviation of the movement of the universal wheel, so that the universal wheel moves in the vertical direction.

[0030] A threaded connector 4 is symmetrically fixedly connected to the outer side of the rectangular cover 3 near the bottom, a screw rod 5 is rotatably connected to the top of the base 1 corresponding to the threaded connector 4, a first reversing gear 6 is fixedly connected to the bottom end of the screw rod 5, a rotating shaft 7 is rotatably connected to the bottom end of the base 1, and a second reversing gear 8 is fixedly connected to the position of the rotating shaft 7 corresponding to the first reversing gear 6;

[0031] A handle 9 is fixedly connected to one end of the rotating shaft 7, and a handrail 10 is fixedly connected to the top of the base 1 corresponding to the handle 9. Ball grooves 11 are equidistantly provided on the outside of the carriage 2, and balls 12 are arranged in the ball grooves 11. Universal wheels 13 are symmetrically arranged at the four corners of the bottom of the base 1, and the universal wheels 13 are connected to the base 1 through a shock absorbing mechanism.

[0032] When it is necessary to sort and transport the express through the logistics cart, the handle 9 can drive the second reversing gear 8 to rotate, and the second reversing gear 8 drives the first reversing gear 6 and the screw rod 5 to rotate through meshing. When the screw rod 5 rotates, it drives the rectangular cover 3 to rise and fall through the threaded connection formed with the threaded connector 4. When taking and placing items located at the bottom of the car box 2, the rectangular cover 3 is moved downward, which is convenient for taking and placing items located at the bottom of the car box 2. When the rectangular cover 3 moves upward and its top exceeds the top of the car box 2, the volume of the logistics cart can be increased. By setting the liftable rectangular cover 3, the volume of the logistics cart can be adjusted as needed, and it is convenient to take and place items.

[0033] See also Figures 1 to 3There are two screw rods 5 in total, and the texture directions of the external threads of the two screw rods 5 are the same. The first reversing gear 6 and the second reversing gear 8 are perpendicular to each other, and the first reversing gear 6 and the second reversing gear 8 are meshed with each other. The outer diameter of the ball 12 coincides with the inner diameter of the ball groove 11, and the outer diameter of the ball 12 is larger than the inner diameter of the opening of the ball groove 11. When the rectangular cover 3 and the carriage 2 move relative to each other, the carriage 2 contacts the inner wall of the rectangular cover 3 through the ball 12, and the rolling friction between the rectangular cover 3 and the ball 12 replaces the sliding friction between the rectangular cover 3 and the carriage 2, which can effectively reduce the resistance encountered when the rectangular cover 3 is lifted or lowered, so as to drive the rectangular cover 3 to lift or lower, and adjust the volume of the sorting cart.

[0034] See also Figures 1 to 3 The shock absorbing mechanism includes a bracket 14, the top of the universal wheel 13 is fixedly connected to the bracket 14, a damping spring 15 is installed between the bracket 14 and the base 1, and guide grooves 16 are symmetrically penetrated on both sides of the bracket 14.

The guide rod 17 is a cylinder, and the guide rod 17 and the guide groove 16 constitute a guide structure. When the sorting trolley moves, it moves through the universal wheel 13. When the universal wheel 13 is vibrated, the bracket 14 is driven to vibrate, and the bracket 14 is connected to the base 1 through the damping spring 15, which effectively reduces the vibration force transmitted to the sorting trolley by the universal wheel 13, so as to avoid the vibration of the sorting trolley when moving, causing the internal items to collide, so as to protect the items in the sorting trolley, and the universal wheel 13 moves relative to the base 1 during shock absorption, and the guide structure formed by the guide rod 17 and the guide groove 16 prevents the movement of the universal wheel 13 from being offset, so that the universal wheel 13 moves in the vertical direction.

[0035] Working principle: When using the logistics sorting car, Figures 1 to 3As shown, first, when the express needs to be sorted and transported by the logistics cart, the handle 9 can drive the second reversing gear 8 to rotate, and the second reversing gear 8 drives the first reversing gear 6 and the screw rod 5 to rotate through meshing. When the screw rod 5 rotates, it drives the rectangular cover 3 to rise and fall through the threaded connection formed with the threaded connector 4. When taking and placing items located at the bottom of the car box 2, the rectangular cover 3 is moved downward, which is convenient for taking and placing items located at the bottom of the car box 2. When the rectangular cover 3 moves upward and its top exceeds the top of the car box 2, the volume of the logistics cart can be increased. By setting the liftable rectangular cover 3, the volume of the logistics cart can be adjusted as needed, and it is convenient to take and place items. When the rectangular cover 3 and the car box 2 move relative to each other, the car box 2 contacts the inner wall of the rectangular cover 3 through the ball bearings 12.
