Detailed Implementation
[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3This utility model provides an embodiment of a high-performance cross-film, including a cross-film body 1. Protective layers 20 are provided on the top and bottom sides of the cross-film body 1. Multiple pull strips 5 are provided on the top and bottom ends of both the front and rear sides of the cross-film body 1. A sealing strip 3 is provided at the middle left side of the cross-film body 1. Protective blocks 2 are provided on the top and bottom sides of the sealing strip 3. A fixing block 4 is fixedly connected to the front left end of the sealing strip 3. A pin 17 is provided inside the fixing block 4. Two metal wire rings 11 are provided inside the cross-film body 1. A turntable 6 is provided at the right rear end of the cross-film body 1. A rotating shaft 12 is rotatably connected to the middle front end of the turntable 6. The rotating shaft 12 rotates in front of the turntable 6. Through this series of linkages and coordination, the entire cross-film body 1 can be wound up. After winding is complete, to prevent accidental contact by operators that could cause the cross-film body 1 to scatter, a series of components connected to the insert 14, including the mounting plate 8 and the insert 14, can be removed from the rotating shaft 12 to ensure the stability and safety of the cross-film body 1 in its stored state. A base plate 7 is fixedly connected to the bottom side of the turntable 6. A slot 13 is provided at the center of the front side of the rotating shaft 12. The insert 14 is slidably connected to the inner wall of the slot 13. A mounting plate 8 is fixedly connected to the front side of the insert 14. The insert 14 is located at the rear side of the mounting plate 8, and the slot 13 is provided at the front side of the rotating shaft 12. The insert 14 can be inserted into the slot 13 in a tenon-and-mortise manner, thus forming a simple fixing mechanism. A connecting post 15 is fixedly connected to the center of the front side of the mounting plate 8. A connecting plate 9 is fixedly connected to the front side of the connecting post 15. A handle 10 is fixedly connected to the right front side of the connecting plate 9 to simplify the operation. The protective layer 20 is made of polyester fiber to enhance the bonding force with the substrate. The waterproof layer 21 is made of polyvinyl chloride and prevents the cross-film body 1 from getting damp. The right end of the cross-film body 1 is fixedly connected to the outer wall of the rotating shaft 12 for winding up the cross-film body 1.
[0027] Reference Figure 5 The cross-membrane body 1 has sticker layers 19 on both the top and bottom sides. A waterproof layer 21 is provided on the side of the two sticker layers 19 that are separated from each other. A protective layer 20 is provided on the side of the two waterproof layers 21 that are separated from each other. Polyester fiber, with its high strength and wear resistance, protects the internal structure from damage and effectively disperses and bears various stresses such as tension and pressure, preventing the membrane from cracking or deforming. Polyvinyl chloride material has relatively high strength and can withstand certain tensile and puncture forces, making it suitable for waterproof scenarios that may be damaged by external forces. It also has good weather resistance and can maintain the stability of its physical and chemical properties under long-term sunlight, wind and rain and other natural environmental conditions. Its processing performance is good and it can be combined with other materials through hot pressing, coating and other methods to make a cross-membrane waterproof layer 21 with multiple functions.
[0028] Reference Figure 4The fixing block 4 has a limiting groove 18 inside, and a pin 17 is slidably connected inside the limiting groove 18. A handle 16 is fixedly connected to the top of the pin 17. Insert the pin 17 into the limiting groove 18 inside the fixing block 4, and then rotate the handle 16. Under the rotation of the handle 16, the sealing strip 3 will gradually detach from the plastic seal position, and finally achieve the purpose of releasing the safety mechanism, so that the sticker layer 19 can be smoothly separated from the cross film body 1 and the cross film body 1 can be used.
[0029] Working principle: When the cross-film body 1 needs to be rolled up, the operator can manually rotate the handle 10 to rotate the connecting plate 9 and the mounting plate 8. The insert 14 on the rear side of the mounting plate 8 and the slot 13 on the front side of the rotating shaft 12 are mortised and tenoned to form a simple fixing mechanism. The rotating shaft 12 rotates on the front side of the turntable 6. Under the above operation, the cross-film body 1 can be rolled up as a whole. After the cross-film body 1 is stored, a series of parts connected to the insert 14 can be removed to prevent the operator from accidentally touching it and causing the cross-film body 1 to fall apart. When the cross-film body 1 needs to be used, the operator can pull the pull strips 5 on both sides of the cross-film body 1. With the help of the pull strips 5, the sticker layer 19 can be separated from the cross-film body 1, so that the cross-film body 1 can be rolled up. It is usable, and protective blocks 2 are set at both ends of the left side of the cross-film body 1 and the sticker layer 19. The protective blocks 2 are made of elastic soft material to reduce the sharp parts of the cross-film body 1 and the sticker layer 19 from causing injury to the surrounding operators. A sealing strip 3 is set between the two protective blocks 2. The sealing strip 3 is in a plastic seal with the protective blocks 2, and the sealing strip 3 fixes the position of the two protective blocks 2, thereby limiting the position of the sticker layer 19 and preventing the operator from accidentally touching and tearing the sticker layer 19, which would affect the performance of the cross-film body 1. If it is necessary to release the safety mechanism of the sealing strip 3, the operator can insert the pin 17 into the limiting groove 18 opened inside the fixing block 4, and turn the handle 16 to drive the sealing strip 3 out of the plastic seal position, thereby releasing the safety mechanism.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
