[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Embodiment 1

[0019] As Figures 1-4The utility model provides a technical scheme: an anti-aging PVC decorative molding, including PVC decorative molding body 1, the outer surface of PVC decorative molding body 1 is placed with PC board protection cover 2, PC board protection cover 2 can effectively resist the radiation of ultraviolet, by covering the outside of PVC decorative molding body 1, can protect PVC decorative molding body 1 from ultraviolet damage, reach the effect of delaying PVC decorative molding body 1 aging speed, and PC board protection cover 2 is transparent, let the user can also see the color pattern of PVC decorative molding body 1 itself under the condition that PC board protection cover 2 covers PVC decorative molding body 1, avoid reducing the aesthetic degree of PVC decorative molding body 1 itself, and the both sides of PVC decorative molding body 1 are all set with sliding slot 3, the sliding slot 3 is slidably connected with sliding plate piece 4, and sliding plate piece 4 is fixedly connected between PC board protection cover 2, under the help of sliding slot 3 and sliding plate piece 4, let PC board protection cover 2 can stably linearly slide from one end of PVC decorative molding body 1, let PC board protection cover 2 gradually complete the cover setting work of PVC decorative molding body 1, simultaneously under the action of sliding slot 3 and sliding plate piece 4, limit the upward movement of PC board protection cover 2 relative to PVC decorative molding body 1, increase the stability of PVC decorative molding body 1 and PC board protection cover 2 adhesion cover setting, and the both ends of PVC decorative molding body 1 are all set with empty slot 5, and the empty slot 5 is slidably connected with sliding block 6, one side of the sliding block 6 is fixed with positioning column 7, and the positioning column 7 is engaged with sliding plate piece 4, by sliding block 6 in empty slot 5 is pushed to move, drive the positioning column 7 on sliding block 6 to move to the sliding plate piece 4 in sliding slot 3, then positioning column 7 and sliding plate piece 4 are engaged with each other, and PC board protection cover 2 and sliding plate piece 4 are positioned, prevent its front and back movement on PVC decorative molding body 1, further improve the stability of PC board protection cover 2 cover setting on PVC decorative molding body 1.

[0020] Example 2

[0021] As Figures 1-4As shown, a fixing member 8 is fixedly connected to the outer edge surface of the slot 5 on one side, and a bolt 9 is threadedly connected to the fixing member 8. The bolt 9 is threadedly connected to the slider 6. When the positioning post 7 is engaged with the sliding plate 4, the movement of the slider 6 is restricted by installing the bolt 9 on the fixing member 8 and connecting the bolt 9 to the slider 6, thereby improving the stability of the connection between the positioning post 7 and the sliding plate 4. A limiting groove 10 is opened on the surface of the slot 3, and a limiting block 11 is slidably connected in the limiting groove 10. When the PC board protective cover 2 is pushed on the PVC decorative line body 1 and completely covers the PVC decorative line body 1, the limiting block 11 will move to the sealing of the limiting groove 10. The closed end cannot move forward, thus preventing the PC board protective cover 2 from moving forward further. This avoids excessive movement of the PC board protective cover 2, which could cause misalignment between the positioning post 7 and the hole on the sliding plate 4, affecting subsequent connections. One side of the limiting block 11 is fixedly connected to the sliding plate 4. A locking post 12 is fixedly connected to one end surface of the limiting block 11, and the locking post 12 engages with one end surface of the limiting groove 10. When the PC board protective cover 2 completely covers the PVC decorative line body 1, the locking post 12 engages with the limiting groove 10, improving the stability of the PC board protective cover 2 initially covering the PVC decorative line body 1, and facilitating the smooth connection between the positioning post 7 and the hole on the sliding plate 4.

[0022] Working principle:

[0023] like Figures 1-4 As shown, in use, the user first slides the sliding plate 4 and the limiting block 11 at one end of the PC board protective cover 2 into the sliding groove 3 and the limiting groove 10 at one end of the PVC decorative line body 1. During this process, the PC board protective cover 2 is pushed and slid on the PVC decorative line body 1, allowing the PC board protective cover 2 to gradually cover the PVC decorative line body 1. When the limiting block 11 slides to the closed end of the limiting groove 10, it is blocked, causing the entire PC board protective cover 2 to stop moving. At this time, the locking post 12 is engaged in the limiting groove 10, and the PC board protective cover 2 completely covers and protects the PVC decorative line body 1. After that, the empty groove is removed. The slider 6 inside 5 moves, causing the positioning post 7 on the slider 6 to move towards the sliding plate 4 in the slide groove 3. Then, the positioning post 7 engages with the sliding plate 4, positioning the PC board protective cover 2 and the sliding plate 4. Finally, the bolt 9 is installed on the fixing part 8 and connected to the slider 6, restricting the movement of the slider 6. At this time, the PC board protective cover 2 is stably installed on the outer surface of the PVC decorative line body 1, allowing the PC board protective cover 2 to cover and protect the PVC decorative line body 1 from ultraviolet damage, thus slowing down the aging rate of the PVC decorative line body 1.

[0024] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
