[0002] Touchscreen technology is a new type of human-computer interaction input method that allows users to operate and control devices by directly touching the screen. With the advancement of technology, touchscreen technology has been widely used in various devices such as mobile phones, tablets, touchscreen computers, and self-service terminals.

[0003] Chinese patent discloses a novel touchscreen that is easy to install and disassemble (authorization announcement number CN219303000U). This patented technology uses a design of limiting posts, limiting slots, and fixing posts to facilitate the fixing of the touchscreen body to the inside of the mounting frame by installing a protective cover. The installation of the protective cover tightly presses the touchscreen body against the frame, reducing installation steps and improving the installation efficiency of workers. It has good practicality. The design of metal springs and rubber strips facilitates the initial locking of the touchscreen body to the inside of the mounting frame, resulting in good practical effect.

[0004] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: In the installation process of existing touch screens, bolts are often used to tighten the outer frame to the touch screen body. This method is too cumbersome to disassemble and requires specific tools, which is time-consuming and labor-intensive, thereby reducing the operating efficiency of the staff. Utility Model Content

[0005] The technical problem to be solved by this utility model is that in the existing technology, the outer frame of the touch screen is often tightened to the touch screen body with bolts during the installation process, which leads to a cumbersome disassembly process. Therefore, we propose a touch screen that is easy to disassemble and assemble.

[0006] To achieve the above objectives, this application adopts the following technical solution: a touch screen that is easy to assemble and disassemble, comprising a touch screen body, an upper outer frame and a lower outer frame installed at both ends of the touch screen body, an upper housing fixed to the rear end of the upper outer frame, a lower housing fixed to the rear end of the lower outer frame, a rotating rod rotatably passing through the interior of the lower housing, a limit plate fixed to one end of the rotating rod inside the lower housing, a transmission rod slidably connected to both sides inside the lower housing, a locking block fixed to the top of the transmission rod, and a locking groove opened on both sides of the upper housing, the interior of the locking groove being slidably connected to the locking block.

[0007] Preferably, guide rods are fixed on both sides inside the lower housing, and guide grooves are formed on the surface of the transmission rods, with the interior of the guide grooves slidably connected to the guide rods.

[0008] Preferably, spring pieces are fixed on both sides inside the lower housing, and the other end of the spring pieces is fixed to the transmission rod.

[0009] Preferably, a square rod is slidably connected inside the rotating rod, a knob is fixed to one end of the square rod, an insertion rod is fixed to one side of the knob, and a slot is provided at the rear end of the lower housing, with the insertion rod inserted into the slot.

[0010] Preferably, the rotating rod has grooves on both sides inside, and a slider is slidably connected inside the groove, with the other end of the slider fixed to the square rod.

[0011] Preferably, a spring is fixed inside the rotating rod, and the other end of the spring is fixed to the square rod.

[0012] Preferably, both the upper and lower outer frames have mounting slots inside, and the interior of the mounting slots is connected to the touch screen body.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, by pulling the knob, the insert rod is disengaged from the slot. The knob can then be turned, causing the square rod to rotate. Since the inside of the rotating rod has a square groove that matches the square rod, the rotating rod can rotate the limiting plate, releasing the transmission rod from its limit. The spring force of the spring pushes the transmission rod to disengage the locking block from the slot, making it easy for the user to separate the upper and lower outer frames, thus enabling quick disassembly of the touch screen body. At the same time, through the above structure, the mounting slot and the touch screen body fit tightly together, ensuring the stable installation of the touch screen body. The structure is compact, the operation is simple, and it is easy to clean and maintain. Attached Figure Description

A rotating rod 6 passes through the interior of the lower housing 5. A limit plate 7 is fixed to one end of the rotating rod 6 inside the lower housing 5. A transmission rod 8 is slidably connected to both sides of the interior of the lower housing 5. A locking block 9 is fixed to the top of the transmission rod 8. A slot 10 is opened on both sides of the upper housing 4, and the slot 10 is slidably connected to the locking block 9. A spring piece 13 is fixed to both sides of the interior of the lower housing 5, and the other end of the spring piece 13 is fixed to the transmission rod 8. A square rod 14 is slidably connected inside the rotating rod 6. A knob 15 is fixed to one end of the square rod 14, and an insertion rod 16 is fixed to one side of the knob 15. An insertion rod 16 is opened at the rear end of the lower housing 5. The slot 17 is inserted into the insert rod 16. The upper outer frame 2 and the lower outer frame 3 are both provided with mounting slots 21. The inside of the mounting slots 21 is inserted into the touch screen body 1. By pulling the knob 15, the insert rod 16 is disengaged from the slot 17. At this time, the knob 15 can be turned, which will drive the square rod 14 to rotate. Since the inside of the rotating rod 6 is provided with a square slot for use with the square rod 14, the rotating rod 6 can drive the limiting plate 7 to rotate, releasing the transmission rod 8. The spring force of the spring piece 13 pushes the transmission rod 8 to drive the locking block 9 to disengage from the slot 10, which makes it easy for the user to separate the upper outer frame 2 and the lower outer frame 3, thereby realizing the quick disassembly of the touch screen body 1.
