Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for cash register touch screens, and more specifically, to a replaceable protective film structure for a cash register touch screen. Background Technology

[0002] The touchscreen of a cash register is one of the main input devices for cashiers. Customers can complete checkout transactions by directly tapping on the screen. Due to frequent tapping, dirt inevitably accumulates on the touchscreen after prolonged use. This dirt is difficult to clean. For convenience, current technology typically involves applying a protective film to the touchscreen; once dirt accumulates, only the protective film needs to be replaced. However, in actual use, the following problems exist: First, because the touchscreen of a cash register is relatively large, applying the protective film is difficult, making it hard to align with the screen and prone to misalignment. Second, existing protective films are fixed to the touchscreen panel with AB glue, leaving a lot of adhesive residue that is difficult to completely remove during replacement. Over time, this affects the adhesion of subsequent film applications and reduces touch sensitivity. Utility Model Content

[0003] The purpose of this invention is to provide a replaceable protective film structure for a cash register touchscreen. This replaceable protective film structure is used to fix a non-adhesive protective film on the touchscreen panel of the cash register. At the same time, it facilitates quick replacement when the protective film is heavily soiled, thereby improving the replacement efficiency and avoiding the problem of residual adhesive on the touchscreen panel.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A replaceable protective film structure for a cash register touchscreen includes a cash register body. A screen frame is mounted on the top of the cash register body via a bracket. A touchscreen is embedded inside the screen frame. The screen frame has a combination of concave and linear frames along its four perimeter. A non-adhesive protective film is pressed and fixed inside the concave and linear frames, covering the touchscreen area. A threaded post is located at the middle of the front side of the vertical section of the concave frame. A concave bracket is fitted onto the threaded post. The concave bracket is distributed along the inner end of the outer side of the concave frame, and several anti-slip blocks are spaced apart on the lower side of the concave bracket. Several through slots are equidistantly spaced on the inner end of the outer side of the concave frame, each through slot corresponding to an anti-slip block embedded therein, with the bottom surface of the anti-slip block adhering to the perimeter of the non-adhesive protective film. The concave bracket is fixed to the concave frame by screwing a nut into the threaded post.

[0006] As a further optimization of this solution, positioning frames are provided on the rear side of the outer ends of the upper and lower horizontal sections of the concave frame. Insert plates pass through the interior of the positioning frames, and the outer ends of the insert plates are fixed to the upper and lower ends of the rear side of the straight frame.

[0007] As a further optimization of this solution, the outer end faces of the upper and lower horizontal sections of the concave frame are all machined with concave blind grooves, the front end face of the inner side of the concave frame is machined with a slot for embedding a non-adhesive protective film, and the rear end face of the inner side of the concave frame is equidistantly embedded with anti-slip pads, which are in contact with the rear side of the screen frame.

[0008] As a further optimization of this solution, the inner side of the linear frame is machined with a vertical blind groove for mounting on the side of the screen frame. Concave sealing strips are fixed on the inner side of the linear frame above and below the vertical blind groove, and the concave sealing strips are aligned and embedded inside the concave blind groove.

[0009] As a further optimization of this solution, blind grooves are machined on the front ends of the upper and lower sides of the insert plate. A movable locking block is connected inside the blind groove by a spring. The movable locking block extends out and locks into the upper and lower positions of the inner side of the positioning frame under the action of the spring force.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes a combined concave and linear frame structure, which is installed onto an existing screen frame to press and fix the adhesive-free protective film onto the outside of the existing touchscreen. By removing the linear frame on one side and the concave support structure on the other side, the old adhesive-free protective film can be quickly pulled out from the side and replaced with a new one, thus improving the efficiency of protective film replacement. The adhesive-free protective film is pressed and fixed by the concave and linear frames, replacing the traditional AB glue used to fix it to the touchscreen panel, avoiding the problem of residual glue on the touchscreen panel.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] To address the existing problems of large screen sizes on POS terminals, making it difficult to apply protective films, aligning them properly, and easily misaligning them; and the fact that existing protective films are fixed to the touchscreen panel with AB glue, leaving a lot of glue residue that is difficult to remove completely during replacement, which in the long run affects the adhesion of subsequent films and touch sensitivity.

[0020] like Figure 1 As shown, this application includes a cash register body 1. A screen frame is mounted on the top of the cash register body 1 via a bracket. A touch screen 2 is embedded inside the screen frame. A combination of concave frame 4 and straight frame 5 is provided at the four perimeter of the screen frame. A non-adhesive protective film 3 is pressed and fixed inside the concave frame 4 and straight frame 5, covering the area of ​​the touch screen 2. A threaded post 6 is provided at the middle of the front side of the vertical section of the concave frame 4, and a concave bracket 7 is fitted on the threaded post 6.

[0021] like Figure 3 As shown, the concave bracket 7 is distributed along the inner end of the outer side of the concave frame 4, and a number of anti-slip top blocks 11 are spaced apart on the lower side of the concave bracket 7. A number of through slots 12 are spaced evenly on the inner end of the outer side of the concave frame 4. Each through slot 12 is embedded with an anti-slip top block 11, and the bottom surface of the anti-slip top block 11 is attached to the periphery of the surface of the adhesive-free protective film 3. The concave bracket 7 is fixed to the concave frame 4 by screwing the nut 10 into the threaded post 6.

[0022] like Figure 2 As shown, positioning frames 9 are provided on the rear side of the outer ends of the upper and lower horizontal sections of the concave frame 4. Insert plates 8 pass through the inside of the positioning frames 9, and the outer ends of the insert plates 8 are fixed to the upper and lower ends of the rear side of the straight frame 5.

[0023] like Figure 4 and Figure 5As shown, concave blind grooves 14 are machined on the outer end faces of the upper and lower horizontal sections of the concave frame 4. The front end face of the inner side of the concave frame 4 is machined with a slot 15 for embedding the adhesive-free protective film 3, and anti-slip pads 17 are embedded and installed at equal intervals on the rear end face of the inner side of the concave frame 4. The anti-slip pads 17 are in contact with the rear side of the screen frame. The inner side of the straight frame 5 is machined with a vertical blind groove 18 for mounting on the side of the screen frame. Concave sealing strips 16 are fixed on the inner sides of the straight frame 5 above and below the vertical blind groove 18. The concave sealing strips 16 are aligned and embedded in the concave blind groove 14. The front end of the upper and lower sides of the insert plate 8 is machined with blind grooves. The blind grooves are connected to the movable locking blocks 13 by springs. The movable locking blocks 13 extend out under the action of the spring force and are mounted on the upper and lower positions of the inner side of the positioning frame 9.

[0024] Specifically, when installing the adhesive-free protective film 3 of this application, the concave frame 4 needs to be fitted onto one side of the existing screen frame first. Then, the adhesive-free protective film 3 is inserted from the other side along the slot 15 of the concave frame 4. When the adhesive-free protective film 3 is completely inside the concave frame 4, the concave bracket 7 is installed on the concave frame 4 by the nut 10, so that the anti-slip top block 11 of the concave bracket 7 is aligned and enters into each through slot 12. The bottom of the anti-slip top block 11 limits the adhesive-free protective film 3 around its perimeter. Then, the straight frame 5 is snapped on from the other side, so that the concave sealing strip 16 of the straight frame 5 is aligned and embedded into the concave blind groove 14 of the concave frame 4 to achieve a seal. During the process, the insert plate 8 will be aligned and inserted into the positioning frame 9. The movable block 13 is first pushed into the blind groove by the positioning frame 9 under the action of the spring force, and then extends and is snapped onto the upper and lower positions of the inner side of the positioning frame 9 to fix the straight frame 5.

[0025] When it is necessary to replace the heavily soiled adhesive-free protective film 3, reverse the above steps, remove the heavily soiled adhesive-free protective film 3, and replace it with a new adhesive-free protective film 3.
