Description

Technical Field

[0001] This utility model relates to the field of logistics trolley technology, specifically a logistics trolley that is easy to pull in both directions. Background Technology

[0002] To facilitate pushing and pulling operations, logistics trolleys are often equipped with pull rods. On existing logistics trolleys, the pull rods are generally located on one side or the opposite side of the trolley base, making it convenient to manually drive the trolley in the direction of the pull rod. However, in the horizontal direction perpendicular to this direction, the pushing and pulling operation of the trolley is more inconvenient, and the ease of assembly and strength of the assembly between the pull rod and the trolley base are insufficient, affecting actual use. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that existing logistics trolleys can only meet the convenience of manual pushing and pulling operations in the direction of the pull rod, while the pushing and pulling operation of the trolley in the other horizontal direction perpendicular to this direction is relatively inconvenient, and the assembly convenience and assembly strength of the pull rod and the trolley base are insufficient, which affects the actual use. Therefore, this utility model provides a logistics trolley that is easy to pull in both directions.

A retaining sleeve is provided at its bottom, which is laterally engaged with the side edge of the trolley base. A reinforcing plate is provided at the top of the retaining sleeve. The reinforcing plate includes a horizontal plate and a connector on the horizontal plate that abuts against the second pull rod. A rod extends downward from the surface of the horizontal plate and is vertically inserted into the positioning hole of the trolley base. A second mounting plate is provided on the connector. The second mounting plate abuts against the first mounting plate extending laterally from the second pull rod and is positioned by bolts through the mounting holes thereon.

[0008] As a further description of the above technical solution:

[0009] The first pull rod is rotatably connected to the mounting base via a rotating shaft. A limiting plate extends from one side of its bottom.

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Please see Figure 1-5 This utility model provides a technical solution: a logistics trolley that is easy to pull in both directions, comprising:

[0034] Cart base 1;

[0035] The first pull rod 2 is mounted on one side of the trolley base 1 via the mounting seat 3;

[0036] The second pull rod 4 is arranged on the trolley base 1 on the other side adjacent to the first pull rod 2. A retaining sleeve 5 is provided at the bottom of the second pull rod 4. The retaining sleeve 5 is laterally engaged with the side edge of the trolley base 1. A reinforcing plate 6 is provided at the top of the retaining sleeve 5. The reinforcing plate 6 includes a horizontal plate and a connector on the horizontal plate that abuts against the second pull rod 4. A rod 7 extends downward from the surface of the horizontal plate. The rod 7 is vertically inserted into the positioning hole 8 of the trolley base 1. A second mounting plate 10 is provided on the connector. The second mounting plate 10 abuts against the first mounting plate 9 extending laterally from the second pull rod 4 and is positioned by bolts through the mounting holes on it.

[0037] The first pull rod 2 is rotatably connected to the mounting base 3 via a rotating shaft 11. A limiting plate 12 extends from one side of its bottom. The surface of the reset rod 14 abuts against the abutment groove 13 of the limiting plate 12, and a tension spring 16 is provided between it and the rotating shaft 11. The end of the reset rod 14 slides through the waist-shaped hole 15 on the side of the mounting base 3. When the logistics trolley needs to be pushed or pulled in the direction of the first pull rod 2, the first pull rod 2 can be held and pressed down appropriately to rotate it along the rotating shaft 11 to adjust the tilt angle, ensuring efficient and labor-saving pushing and pulling. During this time, under the elastic force of the tension spring 16, the reset rod 14 is pulled and moves up and down adaptably within the waist-shaped hole 15, always abutting upward against the abutment groove 13 to ensure the stability of the first pull rod 2. When the first pull rod 2 is released, the tension spring 16 drives the reset rod 14 to move towards the rotating shaft 11, causing the limiting plate 12 to be lifted, and the first pull rod 2 flips upward to reset.

[0038] The sleeve 5 has a C-shaped structure, which improves its snap-fit ​​positioning strength with the trolley base 1.

[0039] The insertion rods 7 are arranged in groups at intervals, with several insertion rods 7 in each group. They are inserted into the waist-shaped positioning holes 8 to improve the stability of the insertion.

[0040] The second mounting plate 10 has a curved cross-section, which allows the second mounting plate 10 to buffer the pulling force when the second pull rod 4 is pushed or pulled, thereby reducing its impact on the structure of the connection between the sleeve 5 and the insertion rod 7 and ensuring the stable assembly of the second pull rod 4.

[0041] The connector is provided with an arc-shaped sleeve 17, which abuts against the surface of the second pull rod 4. The force is further buffered through the contact between the two.

[0042] The assembly process of the second pull rod 4 in a logistics trolley that is easy to pull in both directions in this embodiment includes: the sleeve 5 is laterally snapped into the side edge of the trolley base 1; the insertion rod 7 is aligned with the positioning insertion hole 8, and the reinforcing plate 6 is initially vertically positioned on the top of the sleeve 5; at this time, the first mounting plate 9 and the second mounting plate 10 are spliced ​​together on opposite sides, and the mounting holes on the two are positioned by bolts.

[0043] This logistics trolley features two pull rods on adjacent sides of the trolley base. When the two pull rods are used independently, the trolley can be pulled bidirectionally in two vertical directions, improving ease of operation. When the two pull rods are used together, it is also convenient to move the trolley in all directions.

[0044] In summary, due to the adoption of the above technical solution, the logistics trolley of this embodiment, which is easy to pull in both directions, has the following advantages compared with the prior art:

[0045] This utility model's logistics trolley features two pull rods on adjacent sides of the trolley base. When used independently, the two pull rods allow for bidirectional pulling in two vertical directions, improving operational convenience. When used together, the two pull rods facilitate omnidirectional movement of the trolley. The second pull rod is modularly assembled using a sleeve and a reinforcing plate. The sleeve laterally engages with the trolley base, the rod vertically engages with the base, and the reinforcing plate positions the second pull rod. This mortise and tenon assembly structure enhances the ease of assembly and disassembly of the second pull rod, as well as its overall strength.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
