Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a touch screen with an anti-light-transmission function, including a touch screen main body 100 and a touch screen protection component 200. The touch screen main body 100 is clamped inside the touch screen protection component 200, and an anti-light-transmission component 300 that is easy to replace is clamped between the touch part of the touch screen main body 100 and the touch screen protection component 200;

[0022] The anti-light-transmission component 300 includes a frosted anti-light-transmission soft film 301, and a group of rubber sleeve rings 302 are arranged at the four corners of the frosted anti-light-transmission soft film 301;

[0023] The touch screen protection component 200 includes a bottom shell 201. An installation groove 202 is opened on the bottom shell 201. An annular positioning groove 203 is respectively opened at the four corners of the installation groove 202. A guiding positioning pin 204 is fixed in the annular positioning groove 203, and the four groups of rubber sleeve rings 302 are respectively slidably connected to the four groups of guiding positioning pins 204;

[0024] During use, place the touch screen main body 100 into the bottom case 201, and then fit the four groups of rubber sleeve rings 302 and the four groups of guiding and positioning pins 204 to place the frosted anti-translucent soft film 301. Then cover the protective cover 211 to use it. When it is necessary to replace the frosted anti-translucent soft film 301, open the protective cover 211, remove the rubber sleeve rings 302 and the frosted anti-translucent soft film 301, and then replace them with a new frosted anti-translucent soft film 301 to complete the replacement of the damaged anti-translucent film.

[0025] Cover a layer of anti-translucent frosted soft film on the touch screen main body 100 through the anti-translucent component 300, and fix the anti-translucent component 300 and the touch screen main body 100 through the touch screen protection component 200. At the same time, the touch screen protection component 200 can be easily disassembled and assembled, so that the anti-translucent component 300 can be replaced flexibly and conveniently. As a result, the user can flexibly replace the damaged frosted anti-translucent soft film 301, thereby improving the practicability of the device.

[0026] The touch screen protection component 200 further includes a protective cover 211. The length of the protective cover 211 is the same as that of the bottom case 201, and the width of the protective cover 211 is the same as that of the bottom case 201. An operation slot 213 is opened on the protective cover 211, which is convenient for clamping the touch screen main body 100 between the protective cover 211 and the bottom case 201 to complete the protection of the touch screen main body 100. At the same time, the user can use the touch screen main body 100 through the operation slot 213.

[0027] A set of guiding and positioning buckles 214 are respectively fixed at the four corners of the operation slot 213. The four groups of guiding and positioning buckles 214 and the four groups of guiding and positioning pins 204 are used in cooperation, which is convenient for the engagement of the guiding and positioning buckle 214 and the guiding and positioning pin 204, so that the protective cover 211 can be closed with the bottom case 201.

[0028] The protective cover 211 is buckled on the bottom case 201 through the cooperation of the guiding and positioning buckle 214 and the guiding and positioning pin 204. A rubber sealing ring 212 is clamped between the protective cover 211 and the bottom case 201 to prevent gaps between the bottom case 201 and the protective cover 211, which may cause substances such as dust and water to enter the interior of the touch screen protection component 200 and damage the touch screen main body 100.

[0029] Multiple groups of clamping rubber strips 220 are attached to the side wall of the installation groove 202. The clamping rubber strips 220 are located between the touch screen main body 100 and the side wall of the installation groove 202, which is convenient for fixing the touch screen main body 100 and preventing the touch screen main body 100 from being damaged and scratched due to hitting the installation groove 202.

[0030] At the lower end of the bottom case 201, there is provided a device connection groove 231 which is communicated with the installation groove 202. A pluggable sealing plug 232 is embedded in the device connection groove 231. A limiting pull block 233 is integrally formed at the lower end of the sealing plug 232. When it is necessary to connect the touch screen main body 100 with a connecting wire, the limiting pull block 233 is pulled to pull out the sealing plug 232, and then the touch screen main body 100 can be connected. This can prevent substances such as dust and water from entering the touch screen protection component 200 during normal use and damaging the touch screen main body 100.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
