[0006] To achieve the above objectives, the present invention provides the following technical solution: A button protective film for easy and precise positioning includes an extrusion block, a positioning shell, mounting holes, a positioning label, and a protective film body. The positioning shell has positioning grooves in the middle of both sides of its upper surface. Pull strips are fixedly provided on both sides of the positioning label. Removable adhesive is fixedly provided at the lower ends of the positioning label and the two pull strips. The protective film body includes an anti-slip layer, a sweat-absorbing layer fixedly disposed at the lower end of the anti-slip layer, an elastic layer fixedly disposed at the lower end of the sweat-absorbing layer, a support layer fixedly disposed at the lower end of the elastic layer, and an adhesive layer fixedly disposed at the lower end of the support layer.

[0007] Furthermore, the two pull strips are attached to the inside of the two positioning grooves and the middle of both sides of the positioning shell by removable adhesive.

[0008] Furthermore, the extrusion block is made of rubber material and its size is consistent with the size of the mounting hole and the protective film body.

[0009] Furthermore, a holding strip is fixedly provided at the upper middle part of both the front and rear ends of the positioning shell.

[0010] Furthermore, the anti-slip layer is made of soft PU rubber, and the sweat-absorbing layer is made of calcium chloride filler particles.

[0011] Furthermore, the elastic layer is made of thermoplastic polyurethane, the support layer is made of PET film, and the bonding layer is made of sodium ion release agent.

[0012] This utility model has the following beneficial effects: 1. This utility model proposes a button protective film that facilitates precise positioning. By setting positioning labels, pull strips, positioning shells, and extrusion blocks, it is convenient to accurately position the protective film body above the button when applying the protective film body to the button. This ensures a perfect match with the button layout, avoids air bubbles and misalignment, thereby improving operational accuracy and preventing accidental touches. The tight fit also reduces edge lifting and wear, improves the efficiency of the protective film body's application to the button, and extends the lifespan of both the protective film body and the button.

[0013] 2. The present invention proposes a button protective film that facilitates precise positioning. Through the anti-slip layer, sweat-absorbing layer, elastic layer and support layer in the protective film body, the protective film body is improved in terms of sweat absorption and anti-slip treatment during use, which enhances the tactile experience and improves the rebound effect and support of the protective film body during button use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-6 An embodiment of this utility model is provided: a button protective film that is easy to accurately position, including an extrusion block 2, a positioning shell 1, a mounting hole 8, a positioning label 6 and a protective film body 7. Positioning grooves 3 are provided in the middle of both sides of the upper end face of the positioning shell 1. Pull strips 4 are fixedly provided on both sides of the positioning label 6. Removable adhesive 9 is fixedly provided at the lower end of the positioning label 6 and the two pull strips 4. Two pull strips 4 are attached to the inside of the two positioning grooves 3 and the middle of both sides of the positioning shell 1 by removable adhesive 9. The extrusion block 2 is made of rubber material and its size is consistent with the size of the mounting hole 8 and the protective film body 7. Holding strips 5 are fixedly installed at the upper middle of the front and rear ends of the positioning shell 1.

[0018] Specifically, the mounting hole 8, located in the center of the upper surface of the positioning shell 1, fits around the button. Positioning grooves 3, located in the center of both sides of the upper surface of the positioning shell 1, allow the pull strips 4 on both sides of the positioning label 6 to be placed inside the positioning grooves 3. The removable adhesive 9 below the pull strips 4 is used to adhere the label inside the positioning groove 3. The removable adhesive 9 below the positioning label 6 adheres the label to the top of the protective film body 7. The extrusion block 2, made of rubber and matching the size of the mounting hole 8 and the protective film, can be inserted into the mounting hole 8 to compress the protective film body 7 when it is applied to the button, ensuring even pressure and reducing air bubbles during application. Holding strips 5, located at the upper center of both ends of the positioning shell 1, facilitate holding the positioning shell 1 and placing it around the button. This improves the precise positioning of the protective film body 7 during button application, increasing application efficiency and accuracy.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 The protective film body 7 includes an anti-slip layer 701, a sweat-absorbing layer 702 fixedly disposed at the lower end of the anti-slip layer 701, an elastic layer 703 fixedly disposed at the lower end of the sweat-absorbing layer 702, a support layer 704 fixedly disposed at the lower end of the elastic layer 703, and an adhesive layer 705 fixedly disposed at the lower end of the support layer 704. The anti-slip layer 701 is made of soft PU pad, the sweat-absorbing layer 702 is made of calcium chloride filler particles, the elastic layer 703 is made of thermoplastic polyurethane, the support layer 704 is made of PET film, and the bonding layer 705 is made of sodium ion release agent layer.

[0020] Specifically, the anti-slip layer 701 in the protective film body 7 is a soft PU pad, which increases the friction of the surface of the protective film body 7, prevents slippage during pressing, and improves the stability of button operation. The sweat-absorbing layer 702, filled with calcium chloride particles, can absorb finger sweat, keep the buttons and the protective film body 7 dry, prevent button corrosion caused by moisture, and provide protection for the button surface. The elastic layer 703 is made of thermoplastic polyurethane material. The elastic layer 703 also serves as the base layer of the protective film body 7, with high elasticity, wear resistance, and temperature resistance. It absorbs the impact force when the button is pressed, provides elastic support, ensures quick button reset, extends service life, and adapts to the needs of button curvature and edge bending, improving fit. The support layer 704 is a PET film, which can provide a rigid skeleton for the protective film body 7, preventing deformation and tearing. The bonding layer 705 is a sodium ion release agent layer, which weakens the adhesive layer's stickiness and prevents residual adhesive from remaining on the buttons, improving the overall performance and service life of the protective film body 7.

[0021] Working principle: When applying the protective film body 7 to the button, the positioning shell 1 is first moved by the holding strip 5 so that the mounting hole 8 passes through the entire body of the button and is higher than the button. The release film at the bottom of the protective film body 7 is peeled off, and the pull strips 4 on both sides of the positioning label 6 on the protective film body 7 are accommodated in the positioning groove 3. The removable adhesive 9 below the pull strip 4 is used to stick the positioning groove 3 and the positioning shell 1. The protective film body 7 is precisely positioned when applying it to the button. The extrusion block 2 passes through the mounting hole 8 to press the protective film body 7 evenly, so that the protective film body 7 is evenly adhered to the button. Then, the pull strip 4 and the positioning label 6 are peeled off, and the positioning shell 1 is taken out, so that the protective film body 7 and the button are tightly adhered, reducing bubbles and misalignment, and improving the application efficiency of the protective film body 7 to the button.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
