[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up a protection mechanism, start the motor. The motor drives the rotation of the bidirectional threaded rod. When the bidirectional threaded rod rotates, it drives the movement of the internally threaded block. When the internally threaded block moves, it drives the slider to slide on the first limiting rod through the clamping plate. The slider limits the internally threaded block, converting the rotational motion of the internally threaded block into a linear motion. Finally, start the hydraulic cylinder. The hydraulic cylinder drives the movement of the support plate. The support plate drives the movement of the motor and the first limiting rod. Furthermore, it drives the movement of the clamping plate through the connected components. Through the protection mechanism, the contact area between the crystal film screen and the control box is made closer, increasing the number of adhesion points between the glue, the crystal film screen, and the mounting plate, thereby enhancing the firmness of the adhesion. This ensures that the crystal film screen is not easily loosened or detached during daily use or when subjected to slight external forces, guaranteeing the stability and reliability of the equipment. At the same time, it can also fix the crystal film screen to prevent the crystal film screen from accidentally falling off when the glue fails.

[0017] 2. By setting up a positioning mechanism, pull the pull rod. The pull rod drives the movement of the moving plate on the second limiting rod. When the moving plate moves, it drives the contraction of the first spring. When the moving plate moves, it drives the sliding of the sliding plate on the fixed rod through the connecting plate. When the sliding plate moves, it drives the movement of the positioning rod. When the positioning rod moves, it drives the contraction of the second spring. Through the positioning mechanism, when a fault occurs in the crystal film screen, the design of quick disassembly and installation allows maintenance personnel to quickly open the control box cover and directly access the internal electronic components and the crystal film screen. This can save time for troubleshooting and improve the maintenance efficiency. At the same time, the design of quick disassembly and installation can greatly shorten the maintenance time and reduce the workload of maintenance personnel, which means that the maintenance cost can be reduced and the availability and economy of the equipment can be improved.

[0018] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

A hydraulic cylinder 210 is fixedly connected to the inner wall of the control box 1. The corresponding support plate 29 is fixedly connected to the output shaft of the hydraulic cylinder 210 through a coupling. Through the protection mechanism 2, the contact area between the crystal film screen 22 and the control box 1 is closer, which increases the number of attachment points between the glue and the crystal film screen 22 and the control box 1, thereby enhancing the bonding firmness. When in daily use or under slight external force, the crystal film screen 22 is not easily loosened or detached, ensuring the stability and reliability of the device. At the same time, the crystal film screen 22 can also be fixed to prevent the crystal film screen 22 from accidentally falling off when the glue fails. The protection component includes a plurality of mounting grooves 211 opened on the front side of the control box 1. A mounting plate 212 is slidably connected to the inner wall of each of the plurality of mounting grooves 211.

A second spring 310 is fixedly connected to one end of the two positioning rods 39 close to each other. Through the positioning mechanism 3, when the crystal film screen 22 fails, the design of quick disassembly and installation allows maintenance personnel to quickly open the control box cover and directly access the internal electronic components and the crystal film screen 22. This can save the time for troubleshooting and improve the maintenance efficiency. At the same time, the design of quick disassembly and installation can greatly shorten the maintenance time and reduce the workload of maintenance personnel.

[0030] A specific application of this embodiment is as follows: Start the hydraulic cylinder 210, so that the hydraulic cylinder 210 drives the support plate 29 to slide on the slide rod 28. When the support plate 29 slides, it drives the motor 24 and the first limiting rod 27 to move inside the chute 23, and then drives the components associated with the motor 24 and the first limiting rod 27 to move. Then, install the mounting frame 21 in the exact middle of the crystal film screen 22 and connect it to the rear inner wall of the control box 1. Then start the hydraulic cylinder 210 again, so that the hydraulic cylinder 210 drives the motor 24 to move through the support plate 29, and then drives the bidirectional threaded rod 25 and the first limiting rod 27 to move. When it moves to a suitable position, start the motor 24. The motor 24 drives the bidirectional threaded rod 25 to rotate. When the bidirectional threaded rod 25 rotates, it drives the clamping plate 216 to move through the internal threaded block 26. When the clamping plate 216 moves, it drives the slider 215 to slide on the first limiting rod 27. The internal threaded block 26 is limited by the slider 215 and the first limiting rod 27, converting the rotational motion of the internal threaded block 26 into a linear motion. When the clamping plate 216 moves, it contacts the crystal film screen 22 and squeezes the crystal film screen 22, so that there are more attachment points between the crystal film screen 22 and the control box 1, thereby enhancing the bonding firmness. Finally, stop the two clamping plates 216 at the upper and lower parts of the crystal film screen 22 respectively. Start the hydraulic cylinder 210 again, so that the two clamping plates 216 further contact the crystal film screen 22, and then form a clamping fixation on the crystal film screen 22 through the clamping plate 216 and the control box 1, avoiding the phenomenon that the crystal film screen 22 falls during long-term use. Slide the mounting plate 212 into the mounting groove 211, so that the protective plate 213 is connected to the control box 1, thereby protecting the crystal film screen 22 and preventing the crystal film screen 22 from being damaged by external interference. At the same time, the crystal film screen 22 can be viewed through the transparent glass 214.

[0031] There are two positioning mechanisms 3, and the two positioning mechanisms 3 are arranged in a mirror image. Pull the pull rod 31, and the pull rod 31 drives the moving plate 32 to move on the first spring 33. When the pull rod 31 and the moving plate 32 move, they drive the first spring 33 to contract. When the moving plate 32 moves, it drives the sliding plate 38 to slide on the fixed rod 37 through the connecting plate 35. When the sliding plate 38 slides, it drives the positioning rod 39 to move. When the positioning rod 39 moves, it drives the second spring 310 to contract, and at the same time makes the positioning rod 39 separate from the corresponding mounting plate 212, and contacts the restriction of the positioning rod 39 on the mounting plate 212, then the disassembly between the protective plate 213 and the control box 1 can be completed. At the same time, when the mounting plate 212 slides into the mounting groove 211, no force is applied to the pull rod 31. Under the action of the second spring 310, the positioning rod 39 moves, and then the restriction on the mounting plate 212 is completed, and the installation between the protective plate 213 and the control box 1 can be completed.
