DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0020] like Figures 1 to 4A touch screen that is easy to install as shown includes a fixed frame 1, a buckling frame 2 and a touch screen assembly 3, the touch screen assembly 3 is slidably connected to the inner wall of the fixed frame 1, the touch screen assembly 3 is connected to an external wire 5, the buckling frame 2 is slidably connected to the outer wall of the fixed frame 1, the buckling frame 2 is provided with a threading hole 12, the external wire 5 passes through the fixed frame 1 through the threading hole 12, the fixed frame 1 is provided with a limiting hole 6, the buckling frame 2 is provided with a receiving groove 10, the buckling frame 2 is slidably connected to a limiting rod 7, the limiting rod 7 is connected to a moving plate 11, the moving plate 11 is located in the receiving groove 10 and is slidably connected to the receiving groove 10, the limiting rod 7 is sleeved with a spring 8, the two ends of the spring 8 are respectively connected to the moving plate 11 and the side wall of the receiving groove 10, the limiting rod 7 is connected to a control board 9, the fixed frame 1 and the buckling frame 2 are respectively connected to sealing rubber rings 4, a control board 9 is connected to a plurality of groups of limiting rods 7, the left and right sides of the buckling frame 2 are respectively connected to the limiting rods 7, the buckling frame 2 is connected to a dustproof device, and the dustproof device is used to improve the dustproof ability of the touch screen.

[0021] The dustproof device includes a sealing cylinder 13, which is connected to the buckle frame 2. The sealing cylinder 13 is located outside the threading hole 12. The lower side of the sealing cylinder 13 is threadedly connected with a threaded cover 14, and the threaded cover 14 is connected with a rubber sleeve 17. The threaded cover 14 is provided with a through hole 16. The inner diameter of the sealing cylinder 13 gradually decreases from the side away from the outer buckle frame 2 to the side close to the buckle frame 2. Figure 1 and Figure 3 As shown, the inner diameter of the sealing cylinder 13 gradually decreases from bottom to top, the threaded cover 14 is rotatably connected to the resistance cylinder 15 , and the rubber sleeve 17 is connected to the resistance cylinder 15 .

[0022] When the buckling frame 2 is buckled with the fixing frame 1, the touch screen assembly 3 is stably fixed in the fixing frame 1 through the cooperation between the buckling frame 2 and the fixing frame 1. At this time, the limiting rod 7 is inserted into the limiting hole 6, and the limiting rod 7 will not easily slide out of the limiting hole 6 under the elastic force of the spring 8. Figure 1 As shown, the touch screen can be used stably at this time. When the touch screen assembly 3 needs to be disassembled, taking the left limit rod 7 as an example, pull the control plate 9 to the left, and the control plate 9 drives the limit rod 7 and the movable plate 11 to move left, so that the spring 8 is compressed and the limit rod 7 moves left to the limit hole 6. Similarly, pull the right control plate 9 to slide directly downward out of the snap-fit ​​frame 2, thereby releasing the snap-fit ​​frame 2 and the fixed frame 1; the same is true when the fixed frame 1 and the snap-fit ​​frame 2 are snapped.

[0023] The specific implementation process is as follows:

[0024] During installation, the touch screen assembly 3 is slid from bottom to top into the inner side of the fixing frame 1. After the touch screen assembly 3 slides into the inner side of the fixing frame 1, the top part contacts the sealing rubber ring 4. Then, the control panel 9 is pulled outward to contact the buckling frame 2 from bottom to top on the bottom of the fixing frame 1. Before sliding into the buckling frame 2, the external wire 5 is first passed through the threading hole 12, the contact tube 15, the rubber sleeve 17, and the through hole 16 in sequence; so that the external wire 5 can pass out of the fixing frame 1 after the buckling frame 2 is buckled with the fixing frame 1. At this time, the threaded cover 14 is not tightened relative to the sealing tube 13, that is, the rubber sleeve 17 is still located at the bottom inside the sealing tube 13. Since the inner diameter of the bottom of the sealing tube 13 is large, the rubber sleeve 17 will not be squeezed to contact the external wire 5. Therefore, the external wire 5 can slide relative to the sealing tube 13 at this time. When the buckling frame 2 is fully buckled with the fixed frame 1, the limiting rod 7 just moves to the outside of the limiting hole 6. At this time, the control plate 9 is released, and the movable plate 11 and the limiting rod 7 are pulled to move in the direction of the limiting hole 6 under the action of the restoring force of the spring 8, and then the limiting rod 7 is inserted into the limiting hole 6 to complete the buckling of the buckling frame 2 and the fixed frame 1. Then, the external wire 5 is tightened, and then the threaded cover 14 is screwed upward. As the threaded cover 14 moves upward, the abutment cylinder 15 and the rubber sleeve 17 also move upward together, and because the abutment cylinder 15 is rotatably connected to the threaded cover 14, the rubber sleeve 17 can Move upward vertically. As the rubber sleeve 17 moves upward, the rubber sleeve 17 gradually conflicts with the inner wall of the sealing cylinder 13 where the inner diameter is smaller, and then the rubber sleeve 17 is clamped by the inner wall of the sealing cylinder 13. The rubber sleeve 17 is tightly inserted between the inner wall of the sealing cylinder 13 and the outer wall of the external wire 5, thereby completing the sealing of the gap between the external wire 5 and the inner wall of the sealing cylinder 13; at the same time, the external wire 5 is fixed; subsequently, the threaded cover 14 can be loosened downward to release the clamping of the communication wire, and then the buckle frame 2 and the touch screen assembly 3 can be removed in turn. The structure is simple and easy to use.

[0025] The present technical solution fixes the touch screen assembly 3 by fastening the fixing frame 1 and the buckling frame 2, and completes the installation of the touch screen assembly 3 and the fixing frame 1. The buckling of the buckling frame 2 and the fixing frame 1 can be released by pulling the control panel 9, and then the touch screen assembly 3 is disassembled, thereby improving the convenience of disassembly and assembly of the touch screen assembly 3 and improving the practicality of the touch screen. At the same time, a dustproof device is provided, and the gap between the external wire 5 and the threading hole 12 can be closed by twisting the threaded cover 14 to prevent external dust from entering the fixed shell and affecting the use of the touch screen assembly 3, while ensuring the dustproof effect and facilitating the subsequent quick removal of the touch screen assembly 3, further improving the practicality of the touch screen. The dustproof ability of the touch screen is further improved by the sealing rubber ring 4 to prevent dust from entering the fixing frame 1. A plurality of limit rods 7 are provided to improve the buckle stability of the buckling frame 2 and the fixing frame 1. The rubber sleeve 17 can be better inserted into the gap between the external wire 5 and the sealing cylinder 13 by rotating the connected abutment cylinder 15 to close the gap, thereby improving the convenience of operation and disassembly.

[0026] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
