Technical Field
[0001] This utility model relates to the field of light-shielding tape technology, and in particular to a new material light-shielding tape. Background Technology
[0002] Light-shielding tape is a black single- or double-sided tape with light-shielding function. It uses a black film made with a unique printing process as the base material, which has excellent shielding and insulation properties. It is often used to fix LCDs and backlights. Light-shielding tape is a general term and there are many types and colors of light-shielding tape.
[0003] However, with the development of technology, the demand for light-shielding tape is gradually increasing, and the performance requirements are also increasing day by day. Existing light-shielding tape needs to be cut during use. The cut light-shielding tape is easy to stick together with unused light-shielding tape. When using it again, the user has to manually find the end of the previously cut light-shielding tape, which affects the efficiency of use. Therefore, there is a need to provide a new material light-shielding tape to solve the above problems. Utility Model Content

There are two snap-fit grooves, which are symmetrically distributed at the top and bottom ends of the support rod, respectively. There are two grooves on the inner wall of the snap-fit groove, which are symmetrically distributed on both sides inside the snap-fit groove.
[0011] Preferably, a plug-in block is inserted into the middle of the snap-fit groove, and a protrusion is fixedly connected to the outer wall of the plug-in block. The protrusion is snapped into the inside of the groove. There are two plug-in blocks, which are symmetrically distributed at both ends of the support rod. A connecting plate is fixedly connected to the end of the plug-in block away from the support rod. The side of the connecting plate near the plug-in block is in contact with the outer wall of the tape positioning post.
[0012] Preferably, the connecting plate has a shrinkage groove in the middle, and the shrinkage groove passes through the end of the connecting plate away from the plug block. An extension plate is slidably connected in the middle of the shrinkage groove, and there are two extension plates, which are slidably connected in the middle of the two connecting plates respectively. The extension plate is hollow, and a positioning frame is fixedly connected to the end of the extension plate away from the connecting plate. A positioning through groove is opened in the middle of the positioning frame.
[0013] Preferably, a telescopic limiting rod is bolted to the inner wall of the extension plate near the positioning frame, and the end of the telescopic limiting rod away from the extension plate is bolted to the inner wall of the shrink groove away from the extension plate.

[0024] The tape body 1 includes a PET light-shielding layer 4. The bottom of the PET light-shielding layer 4 is provided with an adhesive layer 2, a PVC base layer 3 and an adhesive layer 5. The bottom of the PET light-shielding layer 4 is adhered to the adhesive layer 2, and the bottom of the adhesive layer 2 is provided with the PVC base layer 3. The PET light-shielding layer 4 and the PVC base layer 3 are bonded together by the adhesive layer 2. The side of the PVC base layer 3 away from the PET light-shielding layer 4 is provided with the adhesive layer 5.
[0025] Please see Figure 1 , Figure 2 , Figure 3As shown, the positioning component 6 includes a support rod 7. One end of the support rod 7 is provided with an insertion block 9 and a connecting plate 12. An extension plate 13 is provided in the middle of the connecting plate 12. One end of the extension plate 13 is provided with a positioning frame 17. A telescopic limiting rod 15 is provided in the middle of the extension plate 13. A connecting spring 16 is provided on the outside of the telescopic limiting rod 15. The support rod 7 is inserted into the middle of the tape positioning post 19. A snap-fit groove 8 is opened in the middle of one end of the support rod 7. There are two snap-fit grooves 8, which are symmetrically distributed at the top of the support rod 7 and the middle of the tape positioning post 19. At the bottom, there are two grooves 11 on the inner wall of the snap-fit groove 8, which are symmetrically distributed on both sides of the inside of the snap-fit groove 8. A snap-fit block 9 is inserted into the middle of the snap-fit groove 8, and a protrusion 10 is fixedly connected to the outer wall of the snap-fit block 9. The protrusion 10 is snapped into the inside of the groove 11. There are two snap-fit blocks 9, which are symmetrically distributed at both ends of the support rod 7. A connecting plate 12 is fixedly connected to the end of the snap-fit block 9 away from the support rod 7. The side of the connecting plate 12 close to the snap-fit block 9 is in contact with the outer wall of the tape positioning post 19.
[0026] A contraction groove 14 is provided in the middle of the connecting plate 12, and the contraction groove 14 passes through the end of the connecting plate 12 away from the plug block 9. An extension plate 13 is slidably connected in the middle of the contraction groove 14, and there are two extension plates 13, which are slidably connected in the middle of the two connecting plates 12 respectively. The extension plate 13 is hollow, and a positioning frame 17 is fixedly connected to the end of the extension plate 13 away from the connecting plate 12. A positioning through groove 18 is provided in the middle of the positioning frame 17. A telescopic limit rod 15 is bolted to the inner wall of the end of the extension plate 13 near the positioning frame 17, and the end of the telescopic limit rod 15 away from the extension plate 13 is bolted to the inner wall of the end of the contraction groove 14 away from the extension plate 13. A connecting spring 16 is sleeved on the outside of the telescopic limit rod 15. The two ends of 16 are fixedly connected to the connecting plate 12 and the extension plate 13 respectively. The positioning component 6 is used to position the cut end of the tape. The positioning frame 17 and the positioning groove 18 are used to support the light-shielding tape. After use, the cut end of the light-shielding tape is stuck to the outer wall of the positioning frame 17 away from the tape body 1, so that it can be quickly found next time and the use effect is improved. The connecting spring 16 drives the extension plate 13 to slide inside the shrink groove 14, so that the extension plate 13 drives the positioning frame 17 to shrink. The positioning frame 17 contacts the outside of the tape body 1 to prevent the positioning frame 17 from being too far away from the tape body 1, which would expose the tape body 1 to the air and affect the adhesion of the tape body 1.
[0027] It should be noted that this utility model is a new type of light-shielding tape. In use, the PET light-shielding layer 4 is superimposed on the PVC base layer 3 to improve the light-shielding effect of the tape body 1. A tape positioning post 19 is provided in the middle of the tape body 1 to achieve shaping. The support rod 7 is then inserted into the middle of the tape positioning post 19. The insertion block 9 at one end of the connecting plate 12 is inserted into the inside of the support rod 7. The protrusion 10 on the outer wall of the insertion block 9 engages with the groove 11 on the inner wall of the engagement slot 8. The two insertion blocks 9 are respectively inserted into both ends of the support rod 7, thereby achieving the shaping of the two connecting plates 12 and the support rod 7. The positioning connection with the tape positioning post 19 is rotatably connected to the support rod 7. At this time, the side of the positioning frame 17 near the connecting plate 12 contacts the outer wall of the tape body 1, and the beginning of the light-shielding tape passes through the positioning slot 18 in the middle of the positioning frame 17, which facilitates the positioning of the beginning of the light-shielding tape and facilitates subsequent use. When too much is used, the connecting spring 16 drives the extension plate 13 and the positioning frame 17 to retract in the direction of the connecting plate 12, so that the side of the positioning frame 17 keeps in contact with the outer wall of the tape body 1, preventing the adhesive layer 5 inside the tape from being in contact with the air for a long time, which would affect the adhesiveness of the tape body 1.
