Description

Technical Field

[0001] This utility model relates to the field of locking technology for grid logistics trolleys, specifically to a locking structure for transport grid trolleys. Background Technology

[0002] Grid logistics trolleys are commonly used in logistics turnover. They can conveniently raise the height of the circumferential baffles to a certain extent. One type of grid logistics trolley uses four pillars to adjust the height of the left and right side baffles. The other two sides are equipped with trapdoors for loading and unloading. However, due to the presence of a central sliding rod and outer shell at the pillars, conventional locking structures may fail to insert the bolt into the lock hole or insert it too shallowly when locking the grid logistics trolley. This can cause the trapdoors to easily break open during the transportation of goods, resulting in reduced transportation efficiency and even safety hazards to workers. Utility Model Content

[0003] The purpose of this invention is to solve the problem that conventional locking structures, when facing mesh logistics trolleys, cannot insert the bolt into the lock hole or insert it too shallowly, causing the trapdoor to easily break open during the transportation of goods. This invention provides a locking structure for transport mesh trolleys that can effectively lock the trapdoor to avoid a decrease in transportation efficiency or to prevent safety hazards to workers.

[0004] To achieve the above objectives, this utility model provides a locking structure for a transport vehicle, comprising: Mounting base, the mounting base is disposed on the trapdoor, and the mounting base is provided with a limit groove; A bolt is provided on the mounting base, and an angled plug is provided at one end of the bolt near the column for inserting the bolt into the gap of the column; A locking handle is disposed on the bolt and is adapted to the limiting groove.

[0005] Preferably, the mounting base is provided with an adsorption element on the side near the lock handle for adsorbing the lock handle.

[0006] Preferably, the top end of the limiting groove away from the column is set in an arc shape.

[0007] Preferably, the angled plug is coated with a wear-resistant coating.

[0008] Preferably, the lock handle is provided with an anti-slip sleeve.

[0009] Preferably, a buffer pad is provided on the side of the mounting base that contacts the lock handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a mounting base on the trapdoor to restrict the movement of the bolt in its length direction, and by using a limiting groove and a locking handle to control and limit the depth of the bolt inserted into the column, the locking handle is designed in conjunction with the limiting groove so that the inclined bolt also rotates when the locking rod rotates with the locking handle. As the inclined bolt rotates, the bolt moves towards the column until it contacts the central sliding rod, thereby effectively increasing the depth of the bolt inserted into the column.

[0013] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0014] As described above, this utility model provides a locking structure for a transport vehicle, including a mounting base 1, a bolt 2, and a locking handle 3. The mounting base 1 is mounted on a trapdoor and has a limiting groove 4. The bolt 2 is mounted on the mounting base 1, and an angled plug 21 is provided at one end of the bolt 2 near the column 5 for the bolt 2 to be inserted into the gap of the column 5. The locking handle 3 is mounted on the bolt 2 and is adapted to the limiting groove 4. By providing the mounting base 1 on the trapdoor to restrict the movement of the bolt 2 in its length direction, the limiting groove 4 and the locking handle 3 control and limit the depth of the bolt 2 inserted into the column 5. The locking handle 3, in conjunction with the limiting groove 4, is configured so that the angled plug 21 also rotates when the locking handle 3 rotates. As the angled plug 21 rotates, the bolt 2 moves towards the column 5 until it contacts the central sliding rod 6, thereby effectively increasing the depth of the bolt 2 inserted into the column 5.

[0015] According to the technical solution provided by this utility model, an adsorption element is provided on the side of the mounting base 1 near the lock handle 3 for adsorbing the lock handle 3. It should be noted that this utility model does not specifically limit the adsorption element. For example, the lock handle 3 can be made of iron and the adsorption element can be made of a magnet. Furthermore, wrapping the magnet with a flexible element can prevent the magnet from splitting due to excessive energy during a collision, while also reducing the difficulty of separating the two again.

[0016] In this invention, the top of the limiting groove 4, away from the column 5, is set in an arc shape. This design is to cooperate with the oblique bolt 21 to form a linkage effect. During the locking process, as the locking handle 3 moves along the arc at the top of the limiting groove 4 and toward the column 5, the bolt 2 also rotates along its axis. While the bolt 2 rotates, the oblique bolt 21 gradually rotates until the notch is directly opposite the central slide rod 6, so as to increase the insertion depth of the oblique bolt 21 and thus improve the locking effect.

[0017] In some embodiments, the angled plug 21 is coated with a wear-resistant coating. This invention does not specifically limit the wear-resistant coating, but mainly aims to avoid high wear on the angled plug 21 after long-term use, thereby improving the service life of the locking structure. In specific embodiments, a cobalt carbide coating can be selected, which can effectively improve the service life of the angled plug 21 and reduce the occurrence of failures.

[0018] In this utility model, the lock handle 3 is coated with an anti-slip coating. This design is mainly to improve the user experience of the lock handle 3 during use. For example, a rubber coating can be used. Filling the surface of the lock plate with the rubber coating can improve the feel of the lock handle 3 while reducing the noise that may be generated during use.

[0019] like Figure 2 As shown, a buffer pad 11 is also provided on the side of the mounting base 1 that contacts the lock handle 3. The buffer pad 11 is designed to prevent the lock handle 3 from colliding with the mounting base 1 or the column 5 during back-and-forth movement and generating noise. It can also effectively reduce the possible injury to the staff when excessive force is applied.

[0020] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
