At this time, the movable release block 609 moves to one end of the rectangular rod 602 and is blocked by the rectangular rod 602, so that the continued movement of the rectangular rod 602 will drive the blocking head 604 to move upward through the movable release block 609, and make the groove 610 and the fixed blocking block 607 pass over the blocking head 604, that is, the rectangular rod 602 is in an unrestricted state at this time, and continues to drive the mounting plate 408 to move toward the outside of the mounting frame 1 under the action of the reset stretching of the third reset spring 613, and makes the LCD screen 3 detach from the mounting slot 8.

[0020] Working principle: When the invention is used, when installing the LCD screen 3, the positioning head 412 is first aligned with the position of the positioning sleeve 413, and then the two ends of the LCD screen 3 are held by hand to push the LCD screen 3 toward the mounting plate 408. At the same time, the LCD screen 3 drives the locking rod 401 through the guide tube 410 through the mounting plate 408 and the elastic locking piece 409 through the central control box 2, until the tail of the elastic locking piece 409 is located in the locking groove 407 at one end of the locking rod 401, and the locking rod 401 is locked by the elastic locking piece 409 cooperating with the locking groove 407, wherein the blocking piece 411 is provided to allow the elastic locking piece 409 to expand outward and prevent the elastic locking piece 409 from contracting inward, thereby locking the LCD screen 3 through the central control box 2 and the mounting frame 1. At this time, the installation between the LCD screen 3 and the mounting frame 1 is completed; When the device needs to be disassembled, the LCD screen 3 is continuously pressed against the inner wall of the mounting groove 8, so that the LCD screen 3 drives the mounting plate 408 to squeeze the connecting frame 506 through the central control box 2, and the front and rear connecting frames 506 cooperate with the articulated arm 505 to drive the articulated seat 504 to move toward both ends, and the articulated seat 504 drives the driving sleeve 511 to move toward the inner wall of the extrusion tube 508 under the guidance of the first guide rod 503, and the driving sleeve 511 squeezes the viscous fluid inside the first bellows 509 through the extrusion piston 510, and the viscous fluid passes through the delay fluid channel 517 and enters the second bellows 513, and at the same time, the viscous fluid expands inside the second bellows 513 and drives the energy storage piston 514 to squeeze the energy storage spring 515, wherein since the delay fluid channel 517 is a Tesla valve structure, this makes it very easy for the viscous fluid to flow out of the first bellows 509. A bellows 509 enters the inner wall of the second bellows 513, but it is not easy to flow back from the inner wall of the second bellows 513 to the inner wall of the first bellows 509, so that there is a hysteresis when the viscous fluid on the inner wall of the second bellows 513 flows back to the inner wall of the first bellows 509, that is, when the diamond structure formed by the connecting frame 506 and the articulated arm 505 is squeezed by the mounting plate 408, it will become flat, and at the same time, the viscous fluid enters the inner wall of the second bellows 513 and squeezes the energy storage spring 515, and then under the elastic force of the energy storage spring 515, the second bellows 513 will be continuously squeezed, and the viscous fluid inside the second bellows 513 will slowly return to the inside of the first bellows 509, and the first bellows 509 will expand to drive the driving sleeve 511 to return to its initial state, that is, the diamond structure formed by the connecting frame 506 and the articulated arm 505 will slowly return to its initial state; When the LCD screen 3 drives the mounting plate 408 to squeeze the connecting frame 506 through the central control box 2, the mounting plate 408 drives the rectangular rod 602 to move in the middle of the fixed partition 501. Fig.11 The state is that the liquid crystal display screen 3 is in a normal use state, and the rectangular rod 602 is in contact with the blocking head 604 through the fixed blocking block 607, so that the blocking head 604 blocks the fixed blocking block 607 from moving toward one end of the groove 610; When the LCD screen 3 drives the mounting plate 408 to squeeze the connecting frame 506 through the central control box 2, the rectangular rod 602 moves toward one end of the mounting frame 1. Fig.11 The middle state is described, that is, the rectangular rod 602 drives the movable release block 609 to move toward one end of the blocking head 604, and the tilting effect of the movable release block 609 drives the blocking head 604 to move upward until the groove 610 passes over the bottom of the blocking head 604, wherein the arc of the end of the blocking head 604 corresponding to the position of the movable release block 609 is larger, so that the existence of the groove 610 does not affect the groove 610 driving the blocking head 604 to move upward and squeeze the second return spring 606; When the LCD screen 3 drives the mounting plate 408 to squeeze the connecting frame 506 through the central control box 2, the mounting plate 408 drives the movable sleeve 614 to move toward one end of the mounting frame 1 along the surface of the fixed sleeve 612 through the positioning sleeve 413, and sometimes the positioning sleeve 413 cooperates with the mounting frame 1 to squeeze the third return spring 613; When the movable release block 609 passes over the bottom of the blocking head 604, the LCD screen 3 is released. At this time, the third reset spring 613 is reset and stretched, and the positioning sleeve 413 drives the mounting plate 408 to move away from the mounting frame 1. At the same time, the mounting plate 408 drives the rectangular rod 602 to move, so that the blocking head 604 contacts a surface of the movable release block 609 away from the groove 610. Since the movable release block 609 can move left and right on the fixed rod 608, under the blocking effect of the blocking head 604, the movable release block 609 is in contact with the fixed blocking block 602 along the direction of the fixed rod 608. 07 approaches, and the fixed blocking block 607 is placed on the inner wall of the groove 610. At this time, the movable release block 609 moves to one end of the rectangular rod 602 and is blocked by the rectangular rod 602, so that the continued movement of the rectangular rod 602 drives the blocking head 604 to move upward through the movable release block 609, and makes the groove 610 and the fixed blocking block 607 pass over the blocking head 604, that is, the rectangular rod 602 is in an unrestricted state at this time, and continues to drive the mounting plate 408 to move to the outside of the mounting frame 1 under the action of the reset stretching of the third reset spring 613, and makes the LCD screen 3 detach from the mounting groove 8; When the LCD screen 3 is separated from the installation slot 8, the two ends of the LCD screen 3 are held by hand, and the connecting strip 404 behind the LCD screen 3 is squeezed by fingers, so that the connecting strip 404 squeezes the first return spring 405, and at the same time drives the rack 403 to move, and the rack 403 drives the gear 402 and the locking rod 401 to rotate 90 degrees, so that the end of the elastic locking piece 409 is separated from the locking slot 407. At this time, the movement of the locking rod 401 is not hindered, that is, the LCD screen 3 is pulled outward, and the LCD screen 3 and the central control box 2 can be separated from the installation plate 408, thereby achieving the purpose of quick disassembly; When the LCD screen 3 is accidentally touched and pressed to move toward the inner wall of the mounting frame 1 and then moves to one end away from the mounting frame 1, generally after the accidental touch, the LCD screen 3 will be ejected from the inner wall of the mounting groove 8, and protrude from the wall surface and cannot be retracted without human interference, which makes it easy for pedestrians to be scratched when walking. In the present technical solution, when the LCD screen 3 is ejected from the inside of the mounting groove 8, since the previous movement of the LCD screen 3 toward one end of the mounting frame 1 will cause the viscous fluid inside the first bellows 509 to enter the inside of the second bellows 513, when the LCD screen 3 is ejected, the viscous fluid inside the second bellows 513 will slowly penetrate the inner wall of the mounting groove 8. The delay fluid channel 517 returns to the inner wall of the first bellows 509, and the first bellows 509 expands to drive the driving sleeve 511 to separate from the inner wall of the extrusion tube 508, so that the rhombus structure formed by the articulated arm 505 and the connecting frame 506 gradually recovers to a full state. Since the elastic force of the energy storage spring 515 is greater than the elastic force of the third return spring 613, the connecting frame 506 drives the connecting plate 603 to move toward one end of the mounting frame 1, and the connecting plate 603 drives the mounting plate 408 to move toward one end of the mounting frame 1 through the connecting rod 601, and the mounting plate 408 drives the central control box 2 and the LCD screen 3 to slowly re-enter the interior of the mounting slot 8; At the same time, the mounting plate 408 drives the rectangular rod 602 to move toward one end of the mounting frame 1, so that the rectangular rod 602 drives the fixed blocking block 607 to move toward the blocking head 604. Due to the tilting effect of the fixed blocking block 607, the blocking head 604 is lifted up. Since the fixed blocking block 607 is located on the inner wall of the groove 610 in the previous action, when the blocking head 604 is lifted up by the fixed blocking block 607, the movable release block 609 can move on the fixed rod 608, so that the groove 610 will be pushed by the blocking head 604 and move away from the fixed blocking block 607, so that the blocking head 604 is lifted up. After passing the fixed blocking block 607, it will be placed between the fixed blocking block 607 and the groove 610 under the squeezing action of the second return spring 606, so that the rectangular rod 602 is locked in the moving direction away from the mounting frame 1 through the fixed blocking block 607 and the blocking head 604, that is, it plays a limiting role in the movement of the LCD screen 3 away from the mounting groove 8, so that the LCD screen 3 is locked, and the spring piece 7 is set, wherein the spring piece 7 is located behind the LCD screen 3, which is used to fill the gap between the LCD screen 3 and the mounting groove 8, so as to maintain the stability of the LCD screen 3 inside the mounting groove 8.
