[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example Please see Figures 1 to 3 The present invention provides a technical solution: a non-destructive connector for plastic film, comprising a splicing frame 1, a sliding groove 2 on one side of the splicing frame 1, a splicing seat 3 slidably connected inside the sliding groove 2, an insertion groove 4 on one side of the splicing seat 3, a telescopic groove 5 inside the splicing seat 3, a telescopic column 6 slidably connected inside the telescopic groove 5, a first spring 7 fixedly installed on the top of the telescopic column 6, the top of the first spring 7 fixedly installed on the inner top wall of the telescopic groove 5, and a flexible clamping plate 8 fixedly installed on the bottom of the telescopic column 6.
[0017] Specifically, the upward movement of the flexible clamping plate 8 causes the telescopic column 6 to move, making the telescopic column 6 move upward inside the telescopic groove 5. At the same time, it compresses the first spring 7. Then, the end of the plastic film to be spliced is placed inside the insertion groove 4. At this time, the external force of the flexible clamping plate 8 is released. Under the action of the first spring 7, the telescopic column 6 causes the flexible clamping plate 8 to clamp the plastic film.
[0018] Please refer to Figure 1 to Figure 4 The splicing base 3 has an movable groove 9 on one side inside, and the movable base 10 is slidably connected inside the movable groove 9.
[0019] Specifically, the movable seat 10 will slide inside the movable slot 9.
[0020] Please refer to Figure 1 to Figure 4 A second spring 11 is fixedly installed at the bottom of the movable seat 10, and the bottom of the second spring 11 is fixedly installed on the inner bottom wall of the movable groove 9.
[0021] Specifically, the movable seat 10 moves downward inside the movable slot 9, which compresses the second spring 11.
[0022] Please refer to Figure 1 to Figure 4 The top of the splicing base 3 is provided with a movable groove 12, and a movable pressure plate 13 is slidably connected inside the movable groove 12.
[0023] Specifically, press down on one end of the movable pressure plate 13 to make the movable pressure plate 3 move downward inside the movable groove 12.
[0024] Please refer to Figure 1 to Figure 4 The bottom of the movable pressure plate 13 is fixedly installed on the top side of the movable seat 10, and the top side of the movable seat 10 is fixedly installed with a limit post 14.
[0025] Specifically, the movable seat 10 will cause the limiting post 14 to retract into the movable slot 9.
[0026] Please refer to Figure 1 to Figure 4 A limiting groove 15 is provided on one side of the splicing frame 1, and one end of the limiting post 14 is inserted into the inside of the limiting groove 15.
[0027] Specifically, one end of the limiting post 14 is inserted into the inside of the limiting groove 15.
[0028] In use, first press down one end of the movable pressure plate 13 to make the movable pressure plate 3 move downward inside the movable groove 12. The movable pressure plate 3 will drive the movable seat 10 to move downward inside the movable groove 9, and at the same time compress the second spring 11. At this time, the movable seat 10 will drive the limiting post 14 to retract into the movable groove 9. Then, the splicing seat 3 is inserted into the sliding groove 2, so that the total length of the splicing seat 3 is greater than the width of the plastic film to be spliced. At this time, the flexible clamping plate 8 is moved upward. The flexible clamping plate 8 will drive the telescopic post 6 to move upward inside the telescopic groove 5, and at the same time, the first spring 7 will be compressed. Then, place the end of the plastic film to be spliced into the insertion groove 4. At this time, release the external force of the flexible clamping plate 8. Under the action of the first spring 7, the telescopic post 6 drives the flexible clamping plate 8 to clamp the plastic film.
