DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of the present application.

[0032] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0033] Please refer to Figure 1 - Figure 10 As shown in the drawings, the present embodiment discloses a linkage type watch film applicator, specifically comprising a base 1, a sliding cover 3, a sliding block 4, a roller 6 and a compound gear 5. The base 1 is provided with a groove 12 capable of accommodating a watch 7, and the groove 12 is provided with a positioning device for installing a positioning film 8 on the side. In some embodiments, the watch 7 can be directly installed in the groove 12. The roller 6 is provided with a compound gear 5 at both ends, the roller 6 is rotatably installed on the sliding block 4, the sliding block 4 is slidingly installed on the upper surface of the base 1, the sliding cover 3 is slidingly installed on the upper surface of the base 1, and the first gear of the compound gear 5 is engaged with the upper rack 31 of the sliding cover 3, and the second gear of the compound gear 5 is engaged with the lower rack 11 of the base 1. By pushing the sliding cover 3, the upper rack 31 drives the compound gear 5 to rotate, thereby driving the roller 6 to press the protective film 9 on the screen of the watch 7.

[0034] In the present embodiment, as Figure 3 , 4As shown, in order to adapt to various sizes and shapes of watches 7 on the market, a detachable positioning piece 2 is installed in the groove 12. The material of the positioning piece 2 is EVA. The positioning piece 2 is installed in the groove 12 through the positioning column 13. The surface edge of the groove 12 is provided with a anti-disengagement piece 14 to prevent the positioning piece 2 from disengaging. The central part of the positioning piece 2 is provided with a containing bin for fixing the watch 7. By replacing different positioning pieces 2, the film pasting operation on different size watches 7 can be realized.

[0035] As shown in Figure 4 , the positioning device includes a diaphragm positioning column 16 and a hook 15. The hook 15 and the diaphragm positioning column 16 are located on both sides of the groove 12. The two sides of the hook 15 are slotted, so that it is separated from the base 1 and suspended, and has a certain elasticity.

[0036] As shown in Figure 2 , the base 1 is provided with a first guide strip 17 and a second guide strip 18 which are parallel to each other. The sliding block 4 is clamped on the first guide strip 17 through the barb 41 and slides along the first guide strip 17. The sliding cover 3 is clamped on the second guide strip 18 through the clamping strip 33 and slides along the second guide strip 18. This design makes the roller 6 better extrude and fit the protective film 9 to the screen.

[0037] As shown in Figure 8 , 9 , 10, the first gear of the compound gear 5 is smaller in diameter than the second gear. The first gear is a pinion 52 and the second gear is a gear wheel 51. They are coaxial. Using the principle of leverage, when the sliding cover 3 is pushed, the contact point between the lowest point of the gear wheel 51 and the lower rack 11 of the base 1 is the fulcrum, the contact point between the sliding cover 3 and the pinion 52 is the power input point, and the friction between the roller 6 and the positioning film 8 is the resistance. To push the roller 6 to move in parallel, as shown in Figure 9 , F1XL1=F2XL2, to save effort, the distance of travel should be increased. F1 is the force of the sliding cover 3, F2 is the resistance of the gear to the roller, L1 is the distance of the sliding cover 3, and L2 is the distance of the gear and the roller 6. As shown in Figure 9 , it can be seen that L1>L2, therefore, F1<F2. Only a light push on the sliding cover 3 is needed to complete the film pasting. The roller 6 in the prior art has no gear, and the roller 6 is directly installed at the end of the sliding cover 3. The distance of the sliding cover 3 is the distance of the roller 6, which cannot achieve the effect of saving effort.

[0038] As shown in Figure 1 , the sliding cover 3 is provided with an observation hole 32 in the center for observing the film pasting condition.

[0039] As shown in Figure 9 , 10As shown, the height of the hook 15 is lower than the height of the diaphragm positioning column 16, and the sliding cover 3 is assembled with the base 1 from the side close to the hook 15. When the film is pasted, the design forms a certain inclination angle between the protective film 9 and the screen, which can effectively reduce the generation of bubbles.

[0040] In the embodiment, the surface of the roller 6 is covered with an elastic material layer, which can provide uniform pressure during the film pasting process, avoiding bubbles or wrinkles between the protective film 9 and the screen of the watch 7. In some embodiments, the diameter of the two ends of the roller 6 is larger than the middle, which is beneficial to realize curved film pasting and improve the adaptability and fitting degree of the film pasting.

[0041] In some embodiments, the lower surface of the base 1 is provided with a non-slip pad for increasing the friction between the base 1 and the placement surface to prevent the base 1 from sliding during the film pasting process. The base 1 is also provided with handles on both sides of one end, which facilitates the user to hold and operate, improving the convenience of use.

[0042] In order to understand the disclosure of the utility model more thoroughly and comprehensively, the principle will be further explained in combination with the use mode.

[0043] In actual operation, first, select the appropriate positioning piece 2 according to the model of the watch 7, install it in the groove 12 of the base 1 through the positioning column 13, and fix the upper surface of the positioning piece 2 by the anti-dropping piece 14 and the tail of the hook 15 to ensure stable installation of the positioning piece 2. Then, place the watch 7 in the containing bin of the positioning piece 2 for fixation.

[0044] Then, install the positioning film 8 with the protective film 9 on the positioning device, so that the diaphragm hook of the positioning film 8 is hung on the diaphragm positioning column 16 and the hook 15, as shown in Figure 1 .

[0045] After that, as shown in Figure 9 , 10 , push the sliding cover 3, and the sliding cover 3 slides along the second guide bar 18. The upper rack 31 on the sliding cover 3 drives the pinion 52 of the compound gear 5 to rotate, and the large gear 51 rotates synchronously. Since the diameter of the pinion 52 of the compound gear 5 is smaller than the diameter of the large gear 51, according to the principle of lever force saving, taking the contact point between the lowest point of the large gear 51 and the lower rack 11 of the base 1 as the fulcrum, and the contact point between the sliding cover 3 and the pinion 52 as the power input point, the roller 6 is driven to move in parallel under the condition of force saving. During the movement of the roller 6, the elastic material layer covering the surface of the roller 6 applies uniform pressure to the protective film 9, and the protective film 9 is pressed flat on the screen of the watch 7. During the film pasting process, the user can observe the film pasting status through the observation hole 32 in the center of the sliding cover 3 at any time to ensure the film pasting effect.

[0046] After the film pasting is completed, the sliding cover 3 is slid back to the initial position, and the watch 7 with the pasted film is taken off.

[0047] Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application.
