[0002] Pallets are the most basic and important loading tools in fertilizer storage and logistics, and their condition directly affects the safety and transportation efficiency of fertilizers. Currently, pallets based on RFID tags on the market generally use a method of manually fixing the RFID tags to the upper surface or side of the pallet. However, in actual working conditions, the RFID tags on the upper surface of the pallet will be damaged by external forces during the transportation of goods, resulting in the RFID reader being unable to effectively obtain pallet information. It is also easy to arbitrarily change or replace the RFID tags between pallets, resulting in chaotic and unclear pallet information management. On the other hand, the number of pallets used in fertilizer storage and logistics is large, and manually attaching RFID tags one by one results in a large amount of labor. Long-term work will also lead to mistakes, which is not only time-consuming and labor-intensive, but also causes increased labor costs and low work efficiency. Therefore, developing a pallet that is convenient for labeling and has a protective function for RFID tags is the key to solving the problem. Utility Model Content

A push rod (10) is provided, and the push rod (10) slides horizontally in the limiting hole. The length of the push rod (10) is not less than the length of the limiting hole, and is less than the sum of the length of the limiting hole and the diameter of the vertical hole. Limiting inclined surfaces (11) are provided at the upper and lower ends of the limiting rod (9), and guide inclined surfaces are provided on the guide rod (7) and the push rod (10) corresponding to the limiting inclined surfaces (11). The limiting rod (9) pushes the guide rod (7) or the push rod (10) to slide through the limiting inclined surfaces (11).

[0013] The height of the limiting rod (9) is the sum of the heights of the vertical hole and the guide groove, or the sum of the heights of the vertical hole and the limiting hole.

[0014] The bottom of the limiting groove (5) is axially provided with a sunken sliding groove (12), and a sliding key (13) is provided at the bottom of the limiting strip (6) corresponding to the sliding groove (12). The limiting strip (6) is limited in the limiting groove (5) by the sliding key (13), and the sliding groove (12) ensures that the sliding key (13) can slide with the limiting strip (6), and a stopper (14) is fixed at the end of the sliding groove (12) to limit the sliding distance of the sliding key (13). The stopper (14) is fixed in the sliding groove (12) to prevent it from falling off from the limiting groove (5).

[0015] The seat cover (15) is provided with a recessed sliding groove (12) axially corresponding to the limit strip (6), and a raised sliding key (13) is provided on the top of the limit strip (6) corresponding to the sliding groove (12), which cooperates with the sliding key (13) at the bottom of the limit strip (6) to guide the movement of the limit strip (6).

[0016] The front section of the limiting hole is provided with a slide groove (12), and the front section of the push rod (10) is provided with a slide key (13) that slides with the slide groove (12), and a stopper (14) is fixed at the end of the slide groove (12) to limit the sliding distance of the slide key (13). The stopper (14) is fixed in the slide groove (12) to limit the push rod (10) in the limiting hole to prevent it from falling out of the limiting hole. The front end of the push rod (10) is set to a hemispherical structure. The hemispherical structure plays a role of excessive guidance, preventing the front end of the push rod (10) from being stuck with the RFID tag card (19) after being subjected to force, ensuring that the push rod (10) slides under force, and can prevent the RFID tag card (19) of the pallet from being replaced arbitrarily, resulting in difficulties and confusion in pallet information management; the RFID tag card (19) can only be replaced if the entirety of the tag is destroyed, and the situation of forging or changing the information of the pallet RFID tag card (19) is prevented.

[0017] Countersunk holes (18) are respectively provided on the top edge of the mounting base (3) and the bottom edge of the seat cover (15). The countersunk holes (18) between the mounting base (3) and the seat cover (15) correspond one to one, and a fixed connection is achieved by inserting a pin between the two opposite countersunk holes (18).

[0018] Each outer wall of the mounting base (3) and / or the seat cover (15), or any two opposite outer walls, is provided with an L-shaped wedge strip (16) protruding outward, and the free end of the wedge strip (16) is arranged obliquely upward to form an acute angle with the outer wall of the mounting base (3) and / or the seat cover (15). This structure can make the wedge strip (16) have a certain elasticity, so that the wedge strip (16) can undergo a certain deformation when subjected to force, so as to ensure that the wedge strip (16) does not interfere with the mounting base (3) being inserted into the mounting groove (2). In the embodiment, a right-angled triangle-shaped slot (17) is provided in the mounting groove (2) of the space of the tray body (1) corresponding to the wedge strip (16). The mounting base (3) or the seat cover (15) is pressed downward. When the wedge strip (16) slides to the slot (17), it is snapped into the slot (17) under the elastic action of the wedge strip (16), thereby achieving a fixed connection between the mounting base (3) and the space of the tray body (1). The wedge strip (16) prevents the mounting base (3) from falling off from the space.

[0019] The seat cover (15) is provided in a frame-like structure arranged on the top of the tray body (1), and an inclined surface is provided on the inner edge of the seat cover (15).

[0020] The guide rod (7) and the limit strip (6) are integrally formed.

[0021] The wedge strip (16) and the outer walls of the mounting base (3) and / or the seat cover (15) are integrally formed.

[0022] The free end surface of the limit strip (6) is provided with an inclined surface, or is provided with an arc-shaped surface, and the inclined surface or the arc-shaped surface serves to guide the RFID tag card (19) to move downward, thereby avoiding the situation of being stuck.

[0023] Furthermore, a half groove is provided on the seat cover (15) corresponding to the limiting groove (5), and the limiting strip (6) is limited in the limiting groove (5) by the seat cover (15), which not only plays a fixing function but also facilitates the installation of the limiting strip (6) in the limiting groove (5) and the guide groove.

[0024] The working method of the present invention is as follows: the device is installed in the installation slot (2) of any long side or the space between the two long sides of the tray body (1); when installing the RFID tag card (19), the RFID tag card (19) is aligned with the receiving slot (4), and then the RFID tag card (19) is pressed downward. During the downward movement of the RFID tag card (19), the limit bar (6) is first squeezed, and the limit bar (6) compresses the spring (8) and returns to the limit slot (5). After the RFID tag card (19) completely enters the receiving slot (4), the limit bar (6) is no longer squeezed by the RFID tag card (19), and the spring (8) is no longer forced to reset and moves outward. The limit bar (6) is pushed out and pressed on the edge of the RFID tag card (19), thereby limiting the RFID tag card (19) in the receiving slot (4); at this time, the RFID tag card (19) squeezes the push rod (10), causing the push rod (10) to retreat into the limit hole, and under the action of the guide inclined surface at its end, the limit rod (9) is lifted upward, so that the limit rod (9) enters the guide slot and resists the rear end of the guide rod (7) to prevent the limit bar (6) from being forced to retreat into the limit slot (5), thereby ensuring that the limit bar (6) is always pressed on the edge of the RFID tag card (19), and preventing the RFID tag card (19) from being arbitrarily removed.
