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 component 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.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0019] Please see Figure 1-7One embodiment of this utility model is: a film roll end cap with a self-locking function, including an end cap 1. Three sides of the end cap 1 are provided with mating grooves 6, and mating blocks 7 are staggered inside the mating grooves 6. By providing the mating grooves 6 and mating blocks 7, two end caps 1 can be better spliced ​​and stacked. Another side of the end cap 1 is provided with anti-slip texture 8. The end cap 1 is placed on a base plate 9. By providing the anti-slip texture 8, the end cap 1 can be placed more stably on the base plate 9. Two end caps 1 are installed at both ends of the film roll. A through hole 4 is provided on the end cap 1, and a strap groove 5 is provided on one side of the end cap 1, and the strap groove 5 is connected to the through hole 4. The strap groove 5 allows for the binding of straps. The system provides a binding path for better binding and securing of the film roll, while also ensuring that the binding strap remains inside the binding groove 5 during subsequent transportation, preventing displacement and improving binding stability. The end cap 1 is equipped with a splicing mechanism 2 and a docking mechanism 3. The splicing mechanism 2 includes a groove 21 and a splicing block 23. The groove 21 is located on the side of the end cap 1, and the splicing block 23 is located inside the groove 21. The splicing block 23 is rotatably connected to the inner wall of the groove 21 via a first rotating shaft 22. A first torsion spring is provided on the first rotating shaft 22. Through the first torsion spring, a stop rod 24 is connected to the splicing block 23. A triangular groove 25 is provided on the side of the splicing block 23 away from the stop rod 24.

[0020] Working principle: End caps 1 are stacked sequentially on the base plate 9. At this time, the staggered mating blocks 7 will be engaged in the corresponding mating grooves 6, achieving initial support for the end caps 1. This connects the splicing mechanism 2 at the bottom of the upper end cap 1 with the splicing mechanism 2 at the top of the lower end cap 1, causing the two splicing mechanisms 2 to abut against each other. The lower abutting rod 24 abuts against the top of the upper triangular groove 25, and the upper abutting rod 24 abuts against the bottom of the lower triangular groove 25. When the end cap 1 is subjected to force and needs to shift left or right, the upper and lower abutting rods 24 will move relative to each other. Under the action of the triangular groove 25, the abutting rods 24 cannot move relative to each other, thus preventing the two end caps 1 from shifting left or right, achieving the purpose of self-locking. After the end caps 1 are stacked, the film roll can be bound along the through hole 4 and the binding groove 5 with the binding strap. The setting of the first torsion spring allows the abutting rod 24 to be retracted into the groove 21 when the lower end cap 1 is placed on the base plate 9, preventing the abutting rod 24 from affecting the stability of the lower end cap 1.

[0021] Please see Figure 1-7Based on the above embodiments, in another embodiment of this utility model, the docking mechanism 3 includes a slot 31 and an elastic block 33. The slot 31 is opened on the right side of the end cover 1. The inside of the slot 31 is provided with an inclined surface. The inclined surface can make the elastic block 33 bend and engage with the slot 31. The elastic block 33 is provided on the left side of the end cover 1. There are two slots 31 and two elastic blocks 33. The two slots 31 and two elastic blocks 33 are correspondingly arranged so that the slots 31 and elastic blocks 33 on the two adjacent end covers 1 can dock. The end cover 1 is provided with a sliding groove 32, and the sliding groove 32 is connected to the slot 31. The elastic block 33 is provided with a pressure rod 34. The pressure rod 34 can realize the separation of the two adjacent end covers 1.

[0022] Working principle: When end cap 1 is spliced ​​left and right, the elastic block 33 on the right end cap 1 will engage with the slot 31 on the left end cap 1, thereby splicing the adjacent end caps 1 and making the end caps 1 more stable during transportation and preventing them from separating. When it is necessary to disassemble the end cap 1, press the pressure rod 34 on the elastic block 33 to bend the elastic block 33, and then drag the left end cap 1 to separate the two adjacent end caps 1. The operation is simple and highly practical.

[0023] This utility model provides a film roll end cap with a self-locking function. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
