Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, and in particular to a high-sealing touch screen. Background Technology

[0002] A touchscreen, also known as a touch panel, is a sensor-type liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display screen.

[0003] To maintain the airtightness of the touchscreen, existing touchscreens use sealant for sealing. While the sealant provides excellent waterproof performance, it also makes the touchscreen very difficult to disassemble. It requires repeated heating with a hot air gun or other heating tools to melt the sealant before disassembly can be performed. This makes it impossible for non-professionals to replace the touchscreen, making touchscreen repair and replacement very troublesome. Therefore, improvements are needed. Summary of the Invention

[0004] This utility model discloses a high-sealing touch screen, which aims to solve the technical problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A highly sealed touchscreen, including an outer screen:

[0007] The outer screen is slidably fitted with a shell, and a back plate is tightly fitted to the back of the shell. A first pressure ring is slidably installed inside the shell, and a soft pad is fixedly installed on the inner wall of the shell. A spring is fixedly installed on the back of the first pressure ring, and a second pressure ring is fixedly installed on the back of the spring. A cylinder is fixedly installed on the back of the second pressure ring, and a screw is threaded inside the cylinder.

[0008] In a preferred embodiment, the back of the soft pad is tightly fitted to the outer screen, and the second pressure ring is slidably mounted on the inner wall of the outer casing.

[0009] In a preferred embodiment, the back plate has a circular hole inside, and the screw is slidably installed through the circular hole and the back plate.

[0010] In a preferred embodiment, the back plate has a placement groove on its back side that communicates with the circular hole, and the screw nut is located in the placement groove.

[0011] In a preferred embodiment, the outer screen has a convex cross-section, the front of the outer casing has an opening, and the protruding part of the outer screen is slidably installed with the outer casing through the opening.

[0012] In a preferred embodiment, the back of the outer screen is tightly fitted to the first pressure ring, and the cylinder has a threaded groove inside, through which the cylinder is threadedly installed with a screw.

[0013] As can be seen from the above, the high-sealing touch screen provided by this utility model has the following technical effects.

[0014] Firstly, the outer screen has a convex cross-section. The protruding outer ring of the outer screen interlocks with the outer shell, separated by a soft pad in the middle. The bottom of the outer screen is pushed upward by the spring's rebound force, causing the outer screen and the soft pad to fit tightly together, achieving a seal between the outer screen and the outer shell. While providing a seal, the spring's rebound force can change the rigid connection between the outer screen and the outer shell into an elastic connection, making the outer screen more resistant to impact.

[0015] Secondly, when disassembling the outer screen, the back panel is separated from the outer shell by unscrewing the screws, exposing the cylinder. The cylinder, along with the second pressure ring, spring, and first pressure ring, is then removed from the inside of the outer shell. With the outer screen no longer restricted, it can be disassembled through the back of the outer shell. While maintaining the seal, disassembling the outer screen becomes simple, and subsequent repairs and replacements are easier. Attached Figure Description

[0023] Reference Figures 1-4 A highly sealed touchscreen, comprising an outer screen 101:

[0024] The outer screen 101 is slidably fitted with a housing 102. A back plate 103 is tightly fitted to the back of the housing 102. A first pressure ring 104 is slidably installed inside the housing 102. A soft pad 105 is fixedly installed on the inner wall of the housing 102. The soft pad 105 and the outer screen 101 are tightly abutted together to achieve a seal between the housing 102 and the outer screen 101. A spring 107 is fixedly installed on the back of the first pressure ring 104. The rebound force of the spring 107 provides power for the soft pad 105 and the outer screen 101 to be tightly abutted together. A second pressure ring 106 is fixedly installed on the back of the spring 107. A cylinder 108 is fixedly installed on the back of the second pressure ring 106. A screw 109 is threaded inside the cylinder 108. The screw 109 can facilitate the installation and removal of the outer screen 101.

[0025] In this embodiment, when disassembling the outer screen 101, the back plate 103 is separated from one side of the outer shell 102 by unscrewing the screws 109, exposing the cylinder 108. The cylinder 108, along with the second pressure ring 106, the spring 107, and the first pressure ring 104, is then removed from inside the outer shell 102. With the outer screen 101 no longer restricted, it can be disassembled through the back of the outer shell 102. While maintaining the seal, disassembling the outer screen 101 becomes simple, and subsequent repairs and replacements are easier.

[0026] In a preferred embodiment, the back of the soft pad 105 is tightly fitted to the outer screen 101, and the second pressure ring 106 is slidably installed on the inner wall of the outer casing 102.

[0027] In this embodiment, the second pressure ring 106 is slidably installed with the outer shell 102, so that the second pressure ring 106 can be removed from the outer shell 102.

[0028] In a preferred embodiment, a circular hole is provided inside the back plate 103, and the screw 109 is slidably installed through the circular hole and the back plate 103.

[0029] In this embodiment, the round hole facilitates the insertion and removal of the screw 109.

[0030] In a preferred embodiment, the back plate 103 has a placement groove on its back side that communicates with the round hole, and the nut of the screw 109 is located in the placement groove.

[0031] In this embodiment, the nut is embedded in the back plate 103 by means of a placement groove, making the device more aesthetically pleasing.

[0032] In a preferred embodiment, the outer screen 101 has a convex cross-section, and the outer casing 102 has an opening on the front. The protruding part of the outer screen 101 is slidably installed with the outer casing 102 through the opening.

[0033] In a preferred embodiment, the back of the outer screen 101 is tightly fitted to the first pressure ring 104, and the cylinder 108 has a threaded groove inside, and the cylinder 108 is threadedly installed with the screw 109 through the threaded groove.

[0034] Working principle: When in use, the outer screen 101 has a convex cross section. The protruding outer ring of the outer screen 101 abuts against the outer shell 102, separated by a soft pad 105. The bottom of the outer screen 101 is pushed upward by the rebound force of the spring 107, so that the outer screen 101 and the soft pad 105 fit tightly together, achieving a seal between the outer screen 101 and the outer shell 102.

[0035] When disassembling the outer screen 101, the back plate 103 is separated from the outer shell 102 by unscrewing the screws 109, exposing the cylinder 108. The cylinder 108, along with the second pressure ring 106, spring 107 and first pressure ring 104, is then removed from inside the outer shell 102. The outer screen 101 is no longer restricted and can be disassembled through the back of the outer shell 102.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
