DETAILED DESCRIPTION

[0023] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0024] Some embodiments of the present application provide a packing buckle with a self-locking structure.

[0025] Embodiment one:

[0026] In combination with Figures 1-3 The present application provides a packing buckle with a self-locking structure, which comprises a bottom plate 100, both sides of the bottom plate 100 are fixedly connected with side plates 101, a connecting column 102 and a limiting column 103 are fixedly connected between the two side plates 101, a transmission belt 104 is connected to the connecting column 102, one end of the transmission belt 104 passes through the gap between the limiting column 103 and the bottom plate 100, and the corresponding length is pulled according to the requirement, the bottom plate 100 is provided with a locking mechanism 200 for fixing the transmission belt 104, the locking mechanism 200 can fix the transmission belt 104, and the packing is completed.

[0027] The locking mechanism 200 comprises a transmission shaft 204 fixedly connected between the side plates 101, a connecting block 205 is sleeved on the transmission shaft 204, a transmission plate 202 is fixedly connected to the connecting block 205, a positioning claw 203 in contact with the transmission belt 104 is fixedly connected to the transmission plate 202, a tension spring 201 for pulling the bottom plate 100 is fixedly connected to the bottom plate 100, the bottom plate 100 is tilted to one side by the tension spring 201, the positioning claw 203 moves with the bottom plate 100, and then the transmission belt 104 can be fixed, the positioning claw 203 can be pressed against the transmission belt 104 without additional manual operation, the transmission belt 104 is quickly fixed, and the packing efficiency is significantly improved.

[0028] Specifically, the gap between the limiting column 103 and the bottom plate 100 is the thickness size of the transmission belt 104, and the positioning claw 203 is placed on the limiting column 103.

[0029] According to the embodiments, it is ensured that the transmission belt 104 is clamped and stressed uniformly, slipping or loosening is avoided, the continuous pulling force can be borne in the fixed state, and the high-strength fastening requirement of goods in logistics transportation is met.

[0030] Embodiment two:

[0031] In combination with Figure 3 and Figure 4As shown, on the basis of the first embodiment, the transmission plate 202 is fixedly connected with a sliding rail 207, and a counterweight 208 is movably installed in the sliding rail 207, which is used to control the positioning force of the positioning claw 203 on the transmission belt 104. The bottom plate 100 takes the transmission belt 104 as a center point, and the tension spring 201 is close to one side of the limiting column 103. The closer the counterweight 208 is to the positioning claw 203, the greater the force of the positioning claw 203 on the transmission belt 104, so that the fixing of the transmission belt 104 is more firm. On the contrary, the farther the counterweight 208 is, the smaller the force of the positioning claw 203 on the transmission belt 104, so that the fixing of the transmission belt 104 is not completely fixed. The user can use a certain force to pull the transmission belt 104, so that the transmission belt 104 will not be affected by gravity and fall off, which is convenient for the user to control the length of the transmission belt 104.

[0032] The counterweight 208 is moved towards the positioning claw 203 to increase the pressure of the positioning claw 203 on the transmission belt 104, so that the packaging is more stable, and the goods will not be loose during the process of carrying and transporting. In some cases where the packaging firmness is not high or the length of the transmission belt 104 needs to be adjusted, the counterweight 208 is moved away from the positioning claw 203 to reduce the positioning force, so that the user can pull the transmission belt 104 with a certain force, while preventing the transmission belt 104 from falling off due to gravity. This greatly improves the applicability of the packaging buckle in different scenarios.

[0033] Specifically, the inner wall of the sliding rail 207 is provided with a first anti-skid surface 209, and the side wall of the counterweight 208 is provided with a second anti-skid surface 210 corresponding to the first anti-skid surface 209. The user needs to use a certain force to move the counterweight 208, and will not be affected by the gravity of the user.

[0034] For lighter goods, reducing the positioning force can avoid damage caused by excessive extrusion; for heavier goods, increasing the positioning force can ensure the safety of the goods during the process of carrying and transporting, so that a set of packaging buckles can meet the packaging needs of goods of different weights.

[0035] Further, the counterweight 208 is fixedly connected with a handle 211, which is convenient for the user to pull the counterweight 208 to move. The bottom plate 100 is fixedly connected with an arc block 206, which is convenient for the user to press the bottom plate 100 to tilt to the other side, so that the positioning claw 203 is separated from the transmission belt 104.

[0036] The inner side wall of the arc block 206 is a circular arc transition surface, which is used to guide the tilting of the transmission plate 202, so that the positioning claw 203 is separated from the transmission belt 104.

[0037] Through the above embodiment, it is known that the user presses the arc-shaped block 206 to make the positioning claw 203 disengage from the transmission belt 104, winds the transmission belt 104 around the object, then pulls one end of the transmission belt 104 through the gap between the limiting column 103 and the bottom plate 100, moves the counterweight block 208 to the side away from the positioning claw 203, and then can pull to adjust the length as needed, after locking the object by the transmission belt 104, moves the counterweight block 208 to the position close to the positioning claw 203, and can complete the fixing of the object.

[0038] It should be noted that the terms "comprising", "containing", or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
