[0002] A resistive touchscreen is an input device that operates by detecting pressure at a touch point. It is basically a thin film plus glass structure. Both the film and the glass are coated with an ITO coating. ITO has excellent conductivity and transparency. Many LCD modules use resistive touchscreens. In the field of electronic equipment, resistive touchscreens are widely used in various smart terminals and industrial control equipment due to their cost advantages and ease of operation.

[0003] Traditional resistive touchscreens generally have weak protective structures, mostly lacking effective dust and foreign object intrusion prevention. Dust and debris easily come into contact with and adhere to the touchscreen surface, not only reducing display clarity but also easily damaging the touchscreen. Therefore, those skilled in the art have provided an improved resistive touchscreen to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an improved resistive touchscreen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved resistive touch screen includes a mounting bracket, a resistive touch screen body, a mounting structure, an adjustment structure, and a pressing structure. The mounting bracket houses the resistive touch screen body, and its inner wall has two first movable slots, each containing a mounting structure. The mounting bracket also has two second movable slots, each containing an adjustment structure. A pressing structure is located at the top of the mounting bracket, above the second movable slots.

[0007] As a further embodiment of this utility model: the mounting structure includes a sliding rod, a spring, and a snap-fit ​​block. The two inner walls of the mounting frame are slidably connected to the sliding rods, and the two sliding rods are fixedly connected to a snap-fit ​​block at one end close to each other. The snap-fit ​​block is placed in the first movable groove. A spring is provided on the sliding rod between the snap-fit ​​block and the mounting frame. A pull block is fixedly connected to the end of the sliding rod away from the snap-fit ​​block through the mounting frame. The two outer walls of the resistive touch screen body are provided with snap-fit ​​grooves that are adapted to the snap-fit ​​block.

[0008] As a further embodiment of this utility model: the adjustment structure includes a rotating shaft, a first bevel gear, a guide rod, a threaded rod, a second bevel gear, a threaded sleeve, and a through groove. The rotating shaft is rotatably connected inside the mounting frame, and a turntable is fixedly connected to both ends of the rotating shaft through the mounting frame. The first bevel gear is fixedly connected to the rotating shaft, and the first bevel gear is placed inside the second movable groove. A guide rod is fixedly connected to the top of the second movable groove.

[0009] As a further embodiment of this utility model: the adjustment structure includes a rotating shaft, a first bevel gear, a guide rod, a threaded rod, a second bevel gear, a threaded sleeve, and a through groove. The rotating shaft is rotatably connected inside the mounting frame, and a turntable is fixedly connected to both ends of the rotating shaft through the mounting frame. The first bevel gear is fixedly connected to the rotating shaft, and the first bevel gear is placed inside the second movable groove. A guide rod is fixedly connected to the top of the second movable groove.

[0010] As a further embodiment of this utility model: the pressing structure includes a protruding post, a protruding box, a round rod, a movable sleeve, a connecting frame, a groove, and a pressing block. The protruding box is fixedly connected to the top of the mounting frame and above the second movable groove. A round rod is rotatably connected inside the protruding box. A movable sleeve is fixedly connected to the round rod. A protruding post is fixedly connected to one side of the top of the threaded sleeve through a through groove.

[0011] As a further improvement of this utility model: two connecting brackets are fixedly connected to the round rod, and pressure blocks are fixedly connected to the ends of the two connecting brackets away from the round rod, and grooves are provided on the protruding box.

[0012] As a further improvement of this utility model: a limiting block is fixedly connected to the top of the mounting frame and above the two first movable slots, and a cover plate is placed at the top of the mounting frame and between the two limiting blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device secures the resistive touchscreen body through its mounting structure. By pulling two pull blocks outward, the slide bar moves the latching block into the first movable slot, placing the resistive touchscreen body inside the mounting frame. Under the spring force, the slide bar causes the latching block to engage in the latching slot, firmly installing the resistive touchscreen body within the mounting frame. This effectively prevents the resistive touchscreen body from becoming loose or shifting within the mounting frame. If it is necessary to disassemble the resistive touchscreen body, simply pull the pull blocks to detach the latching block from the latching slot for removal. The entire process is simple and requires no complex tools.

[0015] 2. This device achieves a stable installation of the cover plate through the cooperation of the adjustment structure and the pressing structure. The cover plate is placed on the mounting frame, protecting the resistive touch screen body and effectively preventing dust, debris, and other foreign objects from entering the mounting frame and damaging the touch screen body. Rotating the turntable drives the rotating shaft and the first bevel gear to rotate. Through the meshing of the first bevel gear and the second bevel gear, the threaded rod rotates, which in turn drives the threaded sleeve and the protruding post to move. This, in turn, drives the round rod, the movable sleeve, and the connecting frame to rotate, which in turn causes the pressure block to press against the cover plate, thus fixing the cover plate and ensuring that it can be stably installed on the mounting frame without easily loosening or falling off, thereby continuously and effectively protecting the touch screen body.

[0026] 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.

[0027] Example 1: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 This embodiment provides an improved resistive touchscreen, including a mounting frame 1, a resistive touchscreen body 2, a mounting structure, an adjustment structure, and a pressing structure. The mounting frame 1 houses the resistive touchscreen body 2, and two first movable slots 4 are formed on the inner wall of the mounting frame 1, with the mounting structure located inside each first movable slot 4. The mounting frame 1 also houses two second movable slots 9, with the adjustment structure located inside each second movable slot 9. A pressing structure is located at the top of the mounting frame 1, above the second movable slots 9.

[0028] The mounting structure includes a slide rod 5, a spring 6, and a locking block 7. The two inner walls of the mounting frame 1 are slidably connected to the slide rod 5, and the two slide rods 5 are fixedly connected to the locking block 7 at their close ends. The locking block 7 is placed in the first movable groove 4. A spring 6 is provided on the slide rod 5 between the locking block 7 and the mounting frame 1, and a pull block 8 is fixedly connected to the slide rod 5 at the end away from the locking block 7 through the mounting frame 1. The two outer walls of the resistive touch screen body 2 are provided with locking grooves 3 that are adapted to the locking block 7.

[0029] In use, the two pull blocks 8 are first pulled outwards, causing the slide bar 5 to move the locking block 7 into the first movable slot 4. At this time, the spring 6 is compressed. Then, the resistive touch screen body 2 is placed inside the mounting bracket 1. Under the elastic force of the spring 6, the slide bar 5 moves the locking block 7 towards the resistive touch screen body 2. The locking block 7 is engaged in the locking slots 3 on the two outer side walls of the resistive touch screen body 2, thus firmly installing the resistive touch screen body 2 in the mounting bracket 1. This effectively prevents the resistive touch screen body 2 from becoming loose or shifting in the mounting bracket 1. If it is necessary to remove the resistive touch screen body 2, pull the pull blocks 8, causing the slide bar 5 to move away from the resistive touch screen body 2. The locking block 7 disengages from the locking slot 3, and the resistive touch screen body 2 can be removed. The whole process is simple and does not require complicated tools.

[0030] Example 2: Refer to Figure 1-9This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the adjustment structure includes a rotating shaft 10, a first bevel gear 11, a guide rod 13, a threaded rod 14, a second bevel gear 15, a threaded sleeve 16, and a through groove 17. The rotating shaft 10 is rotatably connected inside the mounting frame 1, and both ends of the rotating shaft 10 are fixedly connected to a turntable 12 through the mounting frame 1. The first bevel gear 11 is fixedly connected to the rotating shaft 10, and the first bevel gear 11 is placed inside the second movable groove 9. The guide rod 13 is fixedly connected to the top of the second movable groove 9.

[0031] The top of the second movable groove 9 is rotatably connected to a threaded rod 14, and the bottom of the threaded rod 14 is fixedly connected to a second bevel gear 15. The first bevel gear 11 and the second bevel gear 15 are meshed together. A threaded sleeve 16 is threadedly connected to the threaded rod 14. The threaded sleeve 16 is L-shaped, and the top of the mounting bracket 1 has two through slots 17 that are adapted to the threaded sleeve 16.

[0032] The pressing structure includes a protruding post 18, a protruding box 19, a round rod 20, a movable sleeve 21, a connecting frame 22, a groove 23, and a pressing block 24. The protruding box 19 is fixedly connected to the top of the mounting frame 1 and above the second movable groove 9. The round rod 20 is rotatably connected inside the protruding box 19. The movable sleeve 21 is fixedly connected to the round rod 20. The protruding post 18 is fixedly connected to one side of the threaded sleeve 16 through the through groove 17. The protruding post 18 is placed inside the movable sleeve 21. Two connecting frames 22 are fixedly connected to the round rod 20. The pressing block 24 is fixedly connected to the end of the two connecting frames 22 away from the round rod 20. The groove 23 is opened on the protruding box 19.

[0033] Limiting blocks 25 are fixedly connected to the top of the mounting frame 1 and above the two first movable slots 4, and a cover plate 26 is placed at the top of the mounting frame 1 and between the two limiting blocks 25.

[0034] In this embodiment, after the resistive touchscreen body 2 is installed and needs to be stored, the cover plate 26 is placed between the two limiting blocks 25. The cover plate 26 protects the resistive touchscreen body 2, effectively preventing dust, debris, etc. from entering the mounting bracket 1 and preventing these foreign objects from damaging the touchscreen body, thus ensuring the normal use and service life of the touchscreen. Then, the turntable 12 is rotated, which drives the rotating shaft 10 to rotate. The first bevel gear 11 on the rotating shaft 10 rotates accordingly. Since the first bevel gear 11 is meshed with the second bevel gear 15, the rotation of the first bevel gear 11 will drive the second bevel gear 15 to rotate. This causes the threaded rod 14 to rotate. When the threaded rod 14 rotates, the threaded sleeve 16 moves along the axial direction of the threaded rod 14 under the restriction of the guide rod 13. When the threaded sleeve 16 moves, it will drive the protruding column 18 to move inside the movable sleeve 21, which will drive the round rod 20 and the movable sleeve 21 to rotate. The connecting bracket 22 and the pressure block 24 on the round rod 20 will also rotate, which will cause the pressure block 24 to press on the cover plate 26 to complete the fixation of the cover plate 26. This ensures that the cover plate 26 can be stably installed on the mounting bracket 1 and will not easily loosen or fall off. Even if the equipment is subjected to vibration or external force during use, the cover plate 26 can be kept stable, thereby continuously and effectively protecting the touch screen body.
