At the same time, relative to the installation frame 2, the first sliding block 14 moves toward the direction close to the installation frame 2 and presses against the first clamping column 51. The second clamping column 52 is tightly driven to rotate, so that the first clamping column 51 and the second clamping column 52 are fitted together until the first rotating groove 12 and the second rotating groove 22 are in corresponding positions. At this time, the first rotating groove 12 and the second rotating groove 22 form a cylindrical cavity for the first clamping column 51 and the second clamping column 52 to rotate, and the fitting surfaces of the first clamping column 51 and the second clamping column 52 are consistent with the side wall of the receiving groove 11, the second sliding block 24 is located in the first plug-in groove 15, and the first sliding block 14 is located in the second plug-in groove 25. At the same time, the inner wall of the buckling groove 26 is fitted with the side wall of the receiving groove 11, and the bottom wall of the buckling groove 26 is fitted with the side of the fixed frame 1 away from the bottom wall of the receiving groove 11.

[0044] Then, the first reset member 512 drives the first lever 511 to rotate in the direction close to the limiting groove 13, so that the first lever 511 is located in the limiting groove 13. At this time, the first lever 511 drives the first clamping column 51 to rotate, and at the same time, the second reset member 522 drives the second lever 521 to rotate. The rotation direction of the second lever 521 is consistent with the rotation direction of the first lever 511. At this time, the second lever 521 drives the second clamping column 52 to rotate, so that the first clamping column 51 and the second clamping column 52 are tightly fitted against each other and rotate synchronously, so that the fitting surfaces of the first clamping column 51 and the second clamping column 52 are inconsistent with the side wall of the accommodating groove 11, so that the installation frame 2 and the fixed frame 1 are not easily separated, thereby achieving the fixation of the installation frame 2 and the fixed frame 1.

[0045] During disassembly, the technician places the side of the installation frame 2 away from the fixed frame 1 on the operating table, and then the technician uses both hands to adjust the two sets of first handles 511 arranged relatively to each other, so that the first handles 511 rotate in the direction away from the limiting groove 13, and the first handles 511 drive the first clamping column 51 to rotate, so that the first clamping column 51 and the second clamping column 52 are tightly fitted, and the first clamping column 51 drives the second clamping column 52 to rotate synchronously until the fitting surface of the first clamping column 51 and the second clamping column 52 is consistent with the side wall of the accommodating groove 11, and then the technician picks up the movable fixed frame 1 in the direction away from the installation frame 2, and the installation frame 2 and the fixed frame 1 can be disassembled.

[0047] During installation, the technician inserts the installation frame 2 into the accommodating groove 11 to fix the installation frame 2 and the fixed frame 1. At this time, the first handle 511 is located in the limiting groove 13. The technician then adjusts the locking block 53 to slide along the direction of the rotation axis of the first clamping column 51 toward the direction close to the locking groove 54, and makes one end of the locking block 53 movably inserted into the locking groove 54. The locking block 53 fits tightly against the inner wall of the locking groove 54, making it difficult for the locking block 53 to separate from the locking groove 54, thereby limiting the rotation of the first handle 511, thereby further improving the firmness of the installation of the LCD screen 3 and reducing the risk of damage to the LCD screen 3.

[0048] Furthermore, in order to facilitate the technicians to install the LCD screen 3 and realize the side positioning of the LCD screen 3, and improve the installation accuracy of the LCD screen 3, the installation frame 2 is provided with a positioning component 4 that allows the LCD screen 3 to be stably located in the installation groove 21.

Then the technician removes the fixing block 6, and the LCD screen 3 can be disassembled, which is convenient for the technician to disassemble the LCD screen 3.

[0054] Further, in order to facilitate the operation of the technicians, a driving member 8 is provided on the rotating disk 71 to drive the rotating disk 71 to rotate. Figure 1 , Figure 4 and Figure 5The driving member 8 includes an operating rod 81 slidably arranged on the rotating disk 71. The operating rod 81 is located on a side of the rotating disk 71 away from the bottom wall of the mounting groove 21, and the operating rod 81 is arranged to protrude from the side wall of the fixed block 6 along the radial direction of the rotating disk 71.

The rotating disk 71 is also provided with a limiting structure 82 for limiting the relative rotation of the operating rod 81 and the rotating disk 71. The limiting structure 82 includes a sliding hole 821 opened on the rotating disk 71. The sliding hole 821 is located on the rotating axis of the rotating disk 71. A sliding rod 822 is slidably arranged in the sliding hole 821. The sliding rod 822 slides along the rotating axis direction of the rotating disk 71. One end of the sliding rod 822 close to the bottom wall of the mounting groove 21 protrudes from the sliding hole 821. One end of the sliding rod 822 protruding from the sliding hole 821 is aligned with the operating rod 8 1 is connected, the sliding hole 821 in the present application is in the shape of a regular quadrilateral, in other embodiments, the sliding hole 821 can also be in the shape of a triangle, a pentagon, a hexagon or other polygonal shape, as long as the sliding rod 822 can slide in the sliding hole 821 and drive the rotating disk 71 to rotate at the same time, a clamping groove 83 is opened on the inner wall of the side of the hole 85, the operating rod 81 is movably located in the clamping groove 83 and movably fits with the inner wall of the clamping groove 83, and a clamping spring 84 is provided on the side of the operating rod 81 away from the rotating disk 71, and the clamping spring 84 always makes the operating rod 81 slide in the direction close to the clamping groove 83, so that the side support plate 61 is always located between the two opposite positioning blocks 41 during the next installation, so that the technicians can install the fixed block 6 conveniently, and a rotary torsion spring 86 is provided at the rotating axis of the fixed block 6 and the rotating disk 71, and the rotary torsion spring 86 always makes the rotating disk 71 rotate.

[0055] During disassembly, the technician adjusts the operating rod 81 to rotate in the clearance hole 85, and the sliding rod 822 rotates synchronously with the operating rod 81. Since the sliding hole 821 is a regular quadrilateral, the sliding rod 822 drives the rotating disk 71 to rotate until the operating rod 81 rotates to the position corresponding to the snap-in groove 83. At this time, the width between the two relative positioning blocks 41 is larger than the size of the LCD screen 3. The compression spring 84 causes the operating rod 81 to slide in the direction close to the snap-in groove 83 and causes the side wall of the operating rod 81 to press against the inner wall of the snap-in groove 83, thereby limiting the rotation of the operating rod 81, thereby maintaining the separation state of the positioning block 41 and the LCD screen 3. Then the technician can use both hands to disassemble the LCD screen 3, which is convenient for the technician to operate.

[0056] During the subsequent installation, the technician adjusts the operating rod 81 to disengage the card slot 83. At this time, the rotary torsion spring 86 causes the rotating disk 71 to rotate, and the rotating disk 71 drives the side support plate 61 to slide away from the positioning block 41, so that the side support plate 61 is always located between the two opposite positioning blocks 41, which is convenient for the technician to install the fixed block 6.

[0057] The implementation principle of an easy-to-position liquid crystal display module in the embodiment of the present application is as follows: during installation, the technician places the fixing frame 1 and the mounting frame 2 on the operating table, and the opening ends of the accommodating groove 11 and the mounting groove 21 are both facing upwards. Then the technician presses the side of the liquid crystal display screen 3 against the inclined surface of the positioning block 41, and moves the liquid crystal display screen 3 toward the bottom wall of the mounting groove 21. The liquid crystal display screen 3 drives the positioning block 41 to slide until the width between the two relative positioning blocks 41 is greater than the size of the liquid crystal display screen 3. At this time, the liquid crystal display screen 3 falls between the pressing blocks 42. Under the action of the elastic member 434, the four pressing blocks 42 approach each other in pairs to achieve the positioning of the side of the liquid crystal display screen 3. At the same time, the positioning block 41 slides in the direction away from the guide slider 432 to clamp the liquid crystal display screen 3 between the mounting frame 2 and the positioning block 41 and correspond to the display hole 23. Then the technician fixes the fixing block 6 to the bottom wall of the mounting groove 21 by bolts.

[0058] Then the technician turns over the installation frame 2 and inserts the installation frame 2 into the receiving groove 11. At this time, the second sliding block 24 drives the first clamping column 51 to rotate, and the first sliding block 14 drives the second clamping column 52 to rotate until the first rotation groove 12 and the second rotation groove 22 are in corresponding positions. The first rotation groove 12 and the second rotation groove 22 are combined into a cavity for the first clamping column 51 and the second clamping column 52 to rotate, so that the first clamping column 51 and the second clamping column 52 are fitted together. At this time, the fitting surface of the first clamping column 51 and the second clamping column 52 is consistent with the side wall of the receiving groove 11, and then the first handle 511 is driven to rotate by the first reset member 512 until the first handle 511 is located in the limiting groove 13. At this time, the first handle 511 is The first clamping column 51 is driven to rotate, and at the same time, the second reset member 522 drives the second handle 521 to rotate, and the second handle 521 drives the second clamping column 52 to rotate, and the first clamping column 51 and the second clamping column 52 are tightly fitted and rotated synchronously, so that the fitting surface of the first clamping column 51 and the second clamping column 52 is inconsistent with the side wall of the accommodating groove 11, so that the installation frame 2 and the fixed frame 1 are not easily separated, and the installation frame 2 and the fixed frame 1 are fixed. Then the technician adjusts the locking block 53 to slide and insert it into the locking groove 54, and the locking block 53 is tightly fitted with the inner wall of the locking groove 54, so that the locking block 53 is not easily separated from the locking groove 54, so as to limit the rotation of the first handle 511 and further improve the firmness of the installation of the LCD screen 3.

[0059] During disassembly, the technician adjusts the locking block 53 to slide so that the locking block 53 is disengaged from the locking groove 54, and then the technician places the installation frame 2 on the operating table away from the fixed frame 1. Then the technician uses both hands to adjust the two sets of first handles 511 arranged relatively to each other so that the first handles 511 are rotated in the direction away from the limit groove 13. The first handles 511 drive the first clamping column 51 to rotate, and the first clamping column 51 drives the second clamping column 52 to rotate synchronously until the fitting surfaces of the first clamping column 51 and the second clamping column 52 are consistent with the side wall of the accommodating groove 11. Then the technician picks up the movable fixed frame 1 in the direction away from the installation frame 2 to realize the disassembly of the installation frame 2 and the fixed frame 1.

[0060] Then the technician adjusts the operation rod 81 to rotate, and the sliding rod 822 rotates synchronously with the operation rod 81, and drives the rotating disk 71 to rotate, and the rotating disk 71 drives the four guide posts 73 and the four side support plates 61 to slide synchronously, until the side support plate 61 drives the positioning block 41 to slide until the width between the two opposite positioning blocks 41 is greater than the size of the LCD screen 3. At this time, the operation rod 81 rotates to the corresponding position of the clamping groove 83, and the clamping spring 84 is used to make the operation rod 81 slide in the direction close to the clamping groove 83, and the side wall of the operation rod 81 is pressed against the inner wall of the clamping groove 83, thereby limiting the rotation of the operation rod 81, and then achieving the positioning block 41 and the LCD screen 3 to keep apart. The technician then picks up the installation frame 2 with both hands and presses the side of the LCD screen 3 close to the display hole 23 to move the LCD screen 3 away from the bottom wall of the installation slot 21, so that the LCD screen 3 and the installation frame 2 are in a separated state. The technician then removes the fixing block 6 to achieve the disassembly of the LCD screen 3. The technician then adjusts the operating lever 81 to disengage the card slot 83. At this time, the rotary torsion spring 86 causes the rotating disk 71 to rotate, and the rotating disk 71 drives the side support plate 61 to slide in the direction away from the positioning block 41, so that the side support plate 61 is always located between the two opposite positioning blocks 41, which is convenient for the technician to install the fixing block 6 later.
