Description

Technical Field

[0001] This utility model belongs to the field of optical screen products, and specifically relates to a splicing structure for a flexible PET screen. Background Technology

[0002] In the field of optical screens, flexible PET screens are a very common type of screen, typically with a thickness between 0.13-0.3mm. They are used in products such as motorized projection screens and floor-mounted screens. In some applications requiring larger or longer screens, it is necessary to splice two or more screens together. Due to the material characteristics of flexible PET screens, they generally cannot be spliced ​​together using welding methods, such as... Figure 1 and Figure 2 As shown, the first screen 1 and the second screen 2 can only overlap and are bonded together with double-sided adhesive 3 to form a connecting part 4. Therefore, the thickness of the connecting part 4 is more than twice the thickness of the screen (0.26-0.6mm or more). When the roller at the top of the first screen 1 rolls the first screen 1 and the second screen 2 for storage and then puts them down for use, indentations 4' are formed on the first screen 1 and the second screen 2. Each rotation of the roller creates an indentation 4' at the corresponding position. Since the first screen 1 and the second screen 2 generally have an optical coating, the indentations 4' are particularly noticeable under certain lighting conditions. Therefore, when consumers see rows of indentations 4', they may perceive a quality problem with the product and refuse to buy it, affecting sales. Thus, the above-mentioned splicing structure in the existing technology has become a pain point in the industry and urgently needs a solution. Utility Model Content

[0018] The specification and claims use certain terms to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." The following descriptions are preferred embodiments of the present invention; however, these descriptions are intended to illustrate the general principles of the invention and are not intended to limit its scope. The scope of protection of this invention is determined by the appended claims.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings. The directional terms such as "upper", "lower", "left", "right", "inner" and "outer" described in the specification are only for better understanding and explanation, and are not intended to limit the present invention.

[0020] Example

[0021] As shown in Figures 3-7, a splicing structure for a flexible PET screen includes a first screen 1 and a second screen 2. The first screen 1 is provided with a plurality of first tongues 1a and / or the second screen 2 is provided with a plurality of second tongues 2a. The first tongues 1a and the second tongues 2a are mutually matched and spaced apart. After the first screen 1 and the second screen 2 are mutually matched by the plurality of first tongues 1a and the plurality of second tongues 2a, adhesive tape 5 is provided on their front and / or back sides, and the first screen 1 and the second screen 2 are connected into a whole by the adhesive tape 5.

[0022] After the first screen 1 and the second screen 2 are mated together by several first tongues 1a and several second tongues 2a, they are connected into a whole by adhesive tape 5. Thus, the only increase in thickness at the splicing point of the first screen 1 and the second screen 2 is the thickness of the adhesive tape 5, which is almost the same as the thickness of the first screen 1 and the second screen 2, resulting in a relatively flat surface. Figure 8 As shown; therefore, when the screen is rolled up and then put down for use, no indentation will be left on the screen. This effectively solves the problem in the industry where soft PET screens leave indentation on the screen when rolled up and then put down for use. The structure is simple and practical.

[0023] Preferred, such as Figure 3A-5BThe first tongue 1a and the second tongue 2a can be rectangular, arc-shaped, trapezoidal, triangular, or elliptical. The triangular and elliptical structures of the first tongue 1a and the second tongue 2a are not shown in the view, but are arranged similarly to rectangular or arc-shaped ones, allowing for adaptive adjustments. When the first tongue 1a and the second tongue 2a are trapezoidal, they can also be upright or inverted trapezoids relative to the screen substrate, as shown below. Figure 5A and Figure 5B As shown.

[0024] More preferably, when the first tongue 1a and the second tongue 2a are rectangular or trapezoidal, the first tongue 1a and the second tongue 2a are also respectively provided with a first latching ear 1a1 and a second latching ear 2a1. By providing the first latching ear 1a1 and the second latching ear 2a1 on the first tongue 1a and the second tongue 2a respectively, the first screen 1 and the second screen 2 can be effectively connected to each other after being spliced, which greatly enhances the tensile strength of the flexible PET screen and makes it more practical.

[0025] More preferably, such as Figure 7A and Figure 7B As shown, the lower side of the first snap-fit ​​ear 1a1 is set as a first arc surface 1a1-1, and the upper side of the second snap-fit ​​ear 2a1 is set as a second arc surface 2a1-1. By setting the lower side of the first snap-fit ​​ear 1a1 as a first arc surface 1a1-1 and the upper side of the second snap-fit ​​ear 2a1 as a second arc surface 2a1-1, the horizontal straight line can be effectively changed into several arcs, further reducing the risk of leaving indentations on the screen when the first screen 1 and the second screen 2 are rolled up and put down at the splicing joint position.

[0026] More preferably, both the first screen 1 and the second screen 2 are provided with an optical coating.

[0027] This utility model relates to a splicing structure for a flexible PET screen, including a first screen and a second screen. The first screen is provided with a plurality of first tongues and / or the second screen is provided with a plurality of second tongues. The first tongues and second tongues are interlocked and spaced apart. After the first screen and the second screen are interlocked by the plurality of first tongues and the plurality of second tongues, adhesive tape is provided on their front and / or back sides, and the first screen and the second screen are connected into a whole by the adhesive tape. Compared with the prior art, after the first screen and the second screen are interlocked by the plurality of first tongues and the plurality of second tongues, and then connected into a whole by the adhesive tape, the only increase in thickness at the splicing position of the first screen and the second screen is the thickness of the tape, which is almost consistent with the thickness of the first screen and the second screen, resulting in a relatively flat surface. Therefore, when the screen is rolled up for storage and then put down for use, no indentations will be left on the screen.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
