Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal panels, and in particular to a liquid crystal panel installation structure. Background Art

[0002] Liquid crystal panel is a flat-panel display technology that uses the optical properties of liquid crystal molecules to display images. It has the characteristics of being light, thin, low power, high definition and having a wide viewing angle. Therefore, liquid crystal panels are widely used in various electronic devices, such as flat-screen TVs, computer monitors, mobile phones, watches and car displays.

[0003] In the prior art, a common LCD panel mounting structure includes a bottom shell and a front frame. The front frame is provided with a buckle, and the bottom shell is provided with a buckle groove. The buckle and the buckle groove are snap-fitted. A mounting groove for placing the LCD panel is opened on the bottom shell. Both the bottom shell and the front frame are provided with mounting holes. Bolts are installed with threads in the mounting holes. When installing the LCD panel, the technician places the LCD panel in the mounting groove and then inserts the front frame into the mounting groove. At this time, the buckle provided on the front frame is pressed against the inner wall of the bottom shell to undergo elastic deformation and then snap-fits with the buckle groove on the bottom shell to clamp the LCD panel between the bottom shell and the front frame. At the same time, the bottom shell and the front frame are snap-fitted to pre-fix the bottom shell and the front frame. Finally, the technician screws the bolts into the mounting holes to fix the bottom shell and the front frame.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: due to the connection method between the buckle and the slot, the buckle and the slot are tightly fastened, and it is not easy for the buckle to undergo elastic deformation and separate from the slot. When the technicians perform subsequent repairs and disassemble the buckle, it is difficult for the technicians to disassemble the buckle, which increases the time cost of repair. In addition, the buckle is subjected to great stress during disassembly and is easy to break. The broken buckle is not conducive to subsequent use and repair, and also reduces the stability of the bottom shell and the front frame during installation, affecting the stability of the LCD panel fixation.

[0006] The present application provides a liquid crystal panel installation structure that adopts the following technical solution:

[0007] A liquid crystal panel mounting structure comprises a bottom shell, a front frame and a liquid crystal panel, the bottom shell being provided with a mounting groove, the front frame being movably inserted into the mounting groove, the liquid crystal panel being arranged between the bottom shell and the front frame, and the bottom shell and the front frame clamp the liquid crystal panel, a fixing block being slidably arranged in the bottom shell, the fixing block sliding along the width direction of the bottom shell, the front frame being provided with a fixing foot at an end close to the bottom shell, the fixing foot being slidably fitted with the fixing block at an end away from the bottom wall of the mounting groove, the fixing foot and the fixing block being provided with two groups, the two groups of the fixing blocks being arranged relative to each other, the two groups of the fixing feet being also arranged relative to each other, each group of the fixing blocks comprising two fixing blocks symmetrically arranged along the inner side wall of the bottom shell, the fixing blocks corresponding to the fixing feet one-to-one, and an adjusting component driving the fixing block to slide is provided on the bottom shell.

[0008] By adopting the above technical solution, during installation, the technician places the LCD panel in the installation groove of the bottom shell, then inserts the front frame into the installation groove, and then drives the fixing block to slide in the direction close to the fixing foot through the provided adjustment component, so that the fixing block and the side of the fixing foot away from the bottom wall of the installation groove are closely attached to each other, so that the fixing foot is not easy to move in the direction away from the bottom shell, thereby achieving the fixing of the front frame and the bottom shell, and clamping the LCD panel between the bottom shell and the front frame;

[0009] During disassembly, the technician drives the fixing block to slide away from the fixing foot by operating the adjustment assembly, so that the fixing block and the fixing foot away from the bottom wall of the installation groove are separated from each other, and the fixing foot moves in the direction away from the bottom shell, so that the front frame and the bottom shell can be disassembled. It is easy for technicians to disassemble, and the fixing block and the fixing foot do not contact each other during disassembly, and it is not easy to break the fixing block and the fixing foot, which improves the stability of the bottom shell and the front frame during installation, helps to improve the stability of the LCD panel installation, and is convenient for later maintenance and disassembly.

[0010] Optionally, a rotating hole is provided on the side wall of the bottom shell, and the adjusting assembly includes a rotating cylinder rotatably arranged in the rotating hole, the rotating cylinder protruding from the inner wall of the bottom shell, and one end of the rotating cylinder protruding from the inner wall of the bottom shell is rotatably provided with a connecting rod, two connecting rods are provided, and the two connecting rods are symmetrically arranged along the center of the rotating axis of the rotating cylinder, and the two connecting rods on one rotating cylinder are used to slide and adjust the same group of two fixed blocks, and the end of the connecting rod away from the rotating cylinder is rotatably connected to the fixed block, and a limiting block is provided in the bottom shell, and a limiting hole is provided on the limiting block for the fixed block to slide through, and the side wall of the fixed block is slidably fitted with the inner wall of the limiting hole, and an adjusting piece for adjusting the rotation of the rotating cylinder is provided in the bottom shell.

[0011] By adopting the above technical solution, during installation, the technician drives the rotating cylinder to rotate in the rotating hole by operating the adjusting member. At this time, the rotating cylinder is reversed, so that when the rotating cylinder rotates, the connecting rod is driven to rotate around the rotation center of the rotating cylinder. At the same time, under the action of the limiting block and the limiting hole, the ends of the two groups of connecting rods away from the rotating cylinder simultaneously drive the two groups of fixing blocks to slide in the direction close to the fixing feet at the same time, thereby fixing the front frame and the bottom shell;

[0012] During disassembly, the technician drives the rotating cylinder to rotate in the rotating hole by operating the adjusting piece. At this time, the rotating cylinder is in forward rotation, so that the rotating cylinder drives the connecting rod to rotate around the rotation center of the rotating cylinder. At the same time, under the action of the limiting block and the limiting hole, the two sets of connecting rods away from the end of the rotating cylinder drive the two sets of fixing blocks to slide in the direction away from the fixing feet at the same time, thereby realizing the disassembly of the front frame and the bottom shell. When installing and disassembling, the technician can operate the two sets of fixing blocks to slide at the same time, which simplifies the operating steps and facilitates the installation, maintenance and disassembly of the technician.

[0013] Optionally, the adjusting member includes a push rod which is slidably penetrated by the rotating axis of the rotating cylinder, a guide column is provided on the outer circumferential wall of the push rod, a guide hole is opened on the inner wall of the rotating cylinder, the guide hole is spirally arranged along the circumferential wall of the rotating cylinder, the end side of the guide column is slidably adapted to the guide hole, and a torsion spring is provided on the outer circumferential wall of the rotating cylinder, the torsion spring makes the rotating cylinder rotate all the time, thereby driving the guide column to slide in a direction away from the bottom shell, the push rod is provided with a limiting structure for limiting the rotation of the push rod, and the push rod is provided with a locking member for maintaining a constant relative position between the push rod and the bottom shell.

[0014] By adopting the above technical solution, during installation, the technician pushes the push rod to slide in the direction close to the bottom shell. Since the push rod is provided with a limit structure to limit the rotation of the push rod, the push rod drives the guide column to slide in the guide hole while the push rod and the guide column do not rotate. In addition, since the guide hole is spirally opened along the circumferential wall of the rotating cylinder on the inner wall of the rotating cylinder, and the guide column and the guide hole are slidably adapted, the guide column slides in the guide hole in the direction close to the bottom shell, and drives the rotating cylinder to reverse, so that the fixing block and the fixing foot are tightly fitted and pressed. The relative position of the push rod and the bottom shell is kept constant by the provided locking piece. The technician can fix the front frame and the bottom shell by pushing the push rod, and the installation operation is simple and quick.

[0015] During disassembly, the technician operates the locking piece to release the restriction on the sliding of the push rod. At this time, the torsion spring drives the rotating cylinder to rotate forward. At the same time, under the action of the guide hole, the rotating cylinder rotates to drive the push rod and the guide column to slide away from the bottom shell, so that the fixed block and the fixed foot are separated from each other. The technician can disassemble the front frame and the bottom shell by operating the locking piece. The disassembly operation is simple and quick.

[0016] Optionally, the locking member includes a stop pin slidably set on the bottom shell, a stop groove slidably adapted to the stop pin is opened on the outer peripheral wall of the top rod, one end of the stop pin is movably inserted into the stop groove, the end side of the stop pin is fitted with the inner peripheral wall of the stop groove, a spring is provided at the end of the stop pin away from the stop groove, and a shift block is provided on the stop pin, and the shift block protrudes from the outer wall of the bottom shell.

[0017] By adopting the above technical solution, during installation, the set spring makes the end of the stop pin away from the spring always press against the side wall of the push rod, and the technician pushes the push rod and the guide column to slide in the direction close to the bottom shell to the position corresponding to the stop pin and the stop groove. At the same time, the spring makes the end of the stop pin away from the spring slide and insert into the stop groove, so that the stop pin is engaged with the inner wall of the stop groove, so that the push rod and the bottom shell maintain a constant relative position, thereby fixing the front frame and the bottom shell, which is convenient for technicians to install;

[0018] During disassembly, the technician moves the shift block to drive the stop pin to slide away from the stop groove until the stop pin is disengaged from the stop groove. At this time, the torsion spring causes the rotating cylinder to rotate forward, and the rotation of the rotating cylinder drives the push rod and the guide column to slide away from the bottom shell, making it easier for technicians to disassemble.

[0019] Optionally, the locking member includes a top screw rotatably disposed on the bottom shell, the top screw is coaxially disposed with the rotating hole, the top screw is threadably adapted to the rotating hole, and the top screw abuts against an end of the push rod away from the bottom shell.

[0020] By adopting the above technical solution, during installation, the technician twists the top screw, and the top screw drives the top rod and the guide column to slide in the direction close to the bottom shell, and the guide column drives the rotating cylinder to rotate, and at the same time, the top screw is fixed with the inner wall of the rotating hole by thread, and the relative position of the top rod and the bottom shell is constant through the self-locking of the thread, so that the front frame and the bottom shell are fixed, which is convenient for technicians to install. At the same time, the top screw is always in the rotating hole, and it is not easy to cause the top rod to slide due to accidental touch, which affects the stability of the fixation of the front frame and the bottom shell;

[0021] During disassembly, the technician twists the top screw, and the top screw moves in the direction away from the top rod. The top screw and the end of the top rod away from the bottom shell do not abut. At this time, the torsion spring causes the rotating cylinder to rotate forward, and the top rod and the guide column slide in the direction away from the bottom shell, thereby realizing the disassembly of the front frame and the bottom shell, which is convenient for technicians to disassemble.

[0022] Optionally, one end of the fixing block close to the fixing foot is in the shape of an inclined surface, the thickness of the fixing block close to the fixing foot is thicker than the thickness of the end away from the fixing foot, the length of one end of the fixing block close to the bottom wall of the mounting groove is shorter than the length of one end away from the bottom wall of the mounting groove, the fixing foot is tightly pressed against the inclined surface of the fixing block, and a receiving groove is provided on the bottom wall of the mounting groove, and the fixing foot is movably inserted into the receiving groove.

[0023] By adopting the above technical solution, during installation, the technician inserts the front frame into the installation groove movably. At this time, the fixing foot is located at the corresponding position of the receiving groove. When the fixing block slides in the direction close to the fixing foot, the fixing block and the inclined surface of the fixing foot are tightly pressed against each other, driving the fixing foot to be inserted into the receiving groove in the direction close to the bottom wall of the installation groove, which makes it easy for the technician to insert the front frame into the pre-fixed position in the installation groove. At this time, the end of the fixing foot close to the bottom wall of the installation groove is tightly fitted with the bottom wall of the receiving groove, thereby improving the tightness of the fixation of the front frame and the bottom shell.

[0024] Optionally, a placement frame corresponding to the liquid crystal panel is provided in the bottom shell, and a positioning bar is provided at one end of the placement frame away from the bottom wall of the mounting groove, and four positioning bars are provided, and the four positioning bars are combined to form a rectangle, and two adjacent positioning bars are not connected to each other, and the liquid crystal panel is arranged between the placement frame and the front frame, and the liquid crystal panel is arranged in the rectangle formed by the four positioning bars, and a buffer pad is provided on the side where the placement frame and the front frame are close to each other, and the buffer pad close to the side of the placement frame is embedded in the rectangle formed by the positioning bars, and the two buffer pads clamp the liquid crystal panel.

[0025] By adopting the above technical solution, a placement frame and a positioning baffle bar are provided at one end of the placement frame away from the bottom wall of the installation groove, so as to facilitate the positioning of the buffer pad and the liquid crystal panel during installation. At the same time, the positioning baffle bars are not connected to each other at the four corners of the liquid crystal panel. When the bottom shell and the front frame are subjected to external force, it is not easy to squeeze and bump the four corners of the liquid crystal panel. The provided buffer pad reduces the impact and vibration of the liquid crystal panel, thereby protecting the integrity and safety of the liquid crystal panel.

The fixing block 12 and the fixing foot 21 are each provided with two groups, and the two groups of fixing blocks 12 are arranged opposite to each other, and the two groups of fixing feet 21 are also arranged opposite to each other. Each group of fixing blocks 12 includes two fixing blocks 12 symmetrically arranged along the inner wall of the bottom shell 1, and the fixing blocks 12 correspond one to one with the fixing feet 21.

[0042] Further, in order to facilitate the technicians to insert the front frame 2 into the pre-installation position in the installation groove 11 and improve the tightness of the front frame 2 and the bottom shell 1, refer to Figure 2 The end of the fixing block 12 close to the fixing foot 21 is in the shape of an inclined surface, the thickness of the end of the fixing block 12 close to the fixing foot 21 is thicker than the thickness of the end away from the fixing foot 21, the length of the end of the fixing block 12 close to the bottom wall of the mounting groove 11 is shorter than the length of the end away from the bottom wall of the mounting groove 11, the end of the fixing foot 21 away from the bottom wall of the mounting groove 11 is tightly pressed against the inclined surface of the fixing block 12, and a receiving groove 14 is provided on the bottom wall of the mounting groove 11, the fixing foot 21 is slidably inserted into the receiving groove 14, and the end of the fixing foot 21 close to the bottom wall of the mounting groove 11 is tightly fitted with the bottom wall of the receiving groove 14.

[0043] During installation, the technician places the liquid crystal panel 3 in the installation groove 11 of the bottom shell 1, and then inserts the front frame 2 into the installation groove 11. At this time, the fixing foot 21 is located at the corresponding position of the receiving groove 14, and then the fixing block 12 is driven by the adjustment component 4 to slide in the direction close to the fixing foot 21, so that the fixing block 12 and the inclined surface of the fixing foot 21 are tightly pressed against each other, and the end of the fixing foot 21 close to the bottom wall of the installation groove 11 is tightly fitted with the bottom wall of the receiving groove 14, so that the fixing foot 21 is not easy to move away from the bottom shell 1, thereby fixing the front frame 2 and the bottom shell 1, and clamping the liquid crystal panel 3 between the bottom shell 1 and the front frame 2;

[0044] During disassembly, the technician drives the fixing block 12 to slide away from the fixing foot 21 by operating the adjustment component 4, so that the inclined surfaces of the fixing block 12 and the fixing foot 21 are separated from each other, and the fixing foot 21 moves away from the bottom shell 1, thereby realizing the disassembly of the front frame 2 and the bottom shell 1.

[0045] At the same time, the bottom shell 1 is provided with an adjustment component 4 that drives the fixed block 12 to slide. Figure 1 and Figure 2 A rotating hole 13 is provided on the side wall of the bottom shell 1 close to the same group of fixed blocks 12. The adjusting assembly 4 includes a rotating cylinder 41 rotatably connected to the rotating hole 13. The rotating axis of the rotating cylinder 41 is perpendicular to the sliding direction of the fixed block 12 and parallel to the bottom wall of the mounting groove 11. The rotating cylinder 41 protrudes from the inner wall of the bottom shell 1. A connecting rod 42 is rotatably provided at one end of the rotating cylinder 41 protruding from the inner wall of the bottom shell 1. The connecting rod 42 is rotatably connected to the outer peripheral wall of the rotating cylinder 41. Two connecting rods 42 are provided. The two connecting rods 42 are arranged along the rotating axis of the rotating cylinder 41. The connecting rod 42 is arranged symmetrically around the center, and one end of the connecting rod 42 away from the rotating cylinder 41 is rotatably connected to the fixed block 12. The two connecting rods 42 on one rotating cylinder 41 can slide and adjust the two fixed blocks 12 in the same group. The rotation axes of the connecting rods 42 are parallel to the rotation axes of the rotating cylinder 41. A limiting block 43 is fixed in the bottom shell 1. A limiting hole 431 is provided on the limiting block 43 for the fixed block 12 to slide through. The side wall of the fixed block 12 is slidably fitted with the inner wall of the limiting hole 431. An adjusting member 44 for adjusting the rotation of the rotating cylinder 41 is provided in the bottom shell 1.

[0046] Reference Figure 3 The adjusting member 44 includes a push rod 441 that slides through the rotation axis of the rotating cylinder 41, and a guide column 442 is fixed on the outer peripheral wall of the push rod 441. The push rod 441 slides along the rotation axis of the rotating cylinder 41. The guide column 442 is arranged perpendicular to the bottom wall of the mounting groove 11, and the guide column 442 is arranged to protrude in the direction close to the front frame 2. A guide hole 443 is opened on the inner wall of the rotating cylinder 41. The guide hole 443 is spirally arranged along the circumferential wall of the rotating cylinder 41. The end side of the guide column 442 is slidably adapted to the guide hole 443. A torsion spring 444 is provided on the outer peripheral wall of the rotating cylinder 41. The torsion spring 444 makes the rotating cylinder 41 rotate all the time, thereby driving the guide column 442 to slide in the direction away from the bottom shell 1.

[0047] In order to prevent the top rod 441 from rotating when sliding in the rotating cylinder 41, a limiting structure 5 for limiting the rotation of the top rod 441 is provided on the top rod 441. The limiting structure 5 includes a limited rotation groove 51 opened on the outer peripheral wall of the top rod 441. The opening direction of the limited rotation groove 51 is consistent with the movement direction of the fixed block 12, and the limited rotation groove 51 is arranged to penetrate in the movement direction of the top rod 441. A limited rotation block 52 corresponding to the limited rotation groove 51 is fixed in the bottom shell 1. The limited rotation block 52 is located at one end of the top rod 441 close to the bottom shell 1, and the limited rotation block 52 is in the shape of a "7". The end of the limited rotation block 52 away from the bottom wall of the mounting groove 11 is inserted into the limited rotation groove 51, and the limited rotation block 52 is slidably adapted to the inner wall of the limited rotation groove 51.

[0048] Furthermore, in order to prevent the fixing block 12 from sliding away from the fixing foot 21 due to the torsion spring 444 when the fixing block 12 is pressed against the fixing foot 21, a locking member 6 is provided on the top rod 441 to keep the top rod 441 and the bottom shell 1 in a constant relative position, as shown in FIG. Figure 4 The locking member 6 includes a stop pin 61 slidably connected to the bottom shell 1, and the sliding direction of the stop pin 61 is parallel to the sliding direction of the fixed block 12. The top rod 441 is provided with a stop groove 62 slidably adapted to the stop pin 61 on the inner wall of the rotation-limiting groove 51. One end of the stop pin 61 is slidably inserted into the stop groove 62, and the end side of the stop pin 61 is in contact with the inner wall of the stop groove 62. A spring 63 is provided at the end of the stop pin 61 away from the stop groove 62. The spring 63 always makes the end of the stop pin 61 close to the stop groove 62 press against the inner wall of the rotation-limiting groove 51. A cavity 65 for the stop pin 61 and the spring 63 to move is provided on the bottom shell 1. A shift block 64 is fixed on the stop pin 61, and the shift block 64 protrudes from the outer wall of the bottom shell 1. A shift groove 66 corresponding to the sliding direction of the shift block 64 is provided on the bottom shell 1.

[0049] During installation, the spring 63 makes the end of the stop pin 61 away from the spring 63 always press against the side wall of the push rod 441, and the technician pushes the push rod 441 and the guide column 442 to slide in the direction close to the bottom shell 1. Since the rotation-limiting block 52 fixed in the bottom shell 1 is slidably adapted with the limited rotation groove 51 provided on the circumferential wall of the push rod 441, the push rod 441 drives the guide column 442 to slide in the guide hole 443, and the push rod 441 and the guide column 442 do not rotate. In addition, since the guide hole 443 is spirally provided on the inner wall of the rotating cylinder 41 along the circumferential wall of the rotating cylinder 41, and the guide column 442 is slidably adapted with the guide hole 443, the guide column 442 is in the guide hole 443. The guide column 442 drives the rotating cylinder 41 to reverse, and the rotating cylinder 41 drives the connecting rod 42 to rotate around the rotation center of the rotating cylinder 41. At the same time, under the action of the limiting block 43 and the limiting hole 431, the end of the connecting rod 42 away from the rotating cylinder 41 drives the fixing block 12 to move toward the direction close to the fixing foot 21. At this time, the stop pin 61 and the stop groove 62 are in corresponding positions. The spring 63 makes the end of the stop pin 61 away from the spring 63 slide and insert into the stop groove 62, so that the stop pin 61 is clamped with the inner wall of the stop groove 62, so that the top rod 441 and the bottom shell 1 maintain a constant relative position, thereby fixing the front frame 2 and the bottom shell 1.

[0050] During disassembly, the technician moves the shift block 64 to drive the stop pin 61 to slide away from the stop groove 62 until the stop pin 61 is disengaged from the stop groove 62. At this time, the torsion spring 444 causes the rotating cylinder 41 to rotate forward. At the same time, under the action of the guide hole 443, the rotating cylinder 41 rotates to drive the top rod 441 and the guide column 442 to slide away from the bottom shell 1. The end of the connecting rod 42 away from the rotating cylinder 41 simultaneously drives the fixed block 12 to move away from the fixed foot 21, thereby realizing the disassembly of the front frame 2 and the bottom shell 1.

[0051] Further, see Figure 5 and Figure 6 A placement frame 7 corresponding to the liquid crystal panel 3 is movably provided in the bottom shell 1, and the placement frame 7 is movably placed between the bottom shell 1 and the front frame 2. A positioning baffle 71 is fixed to one end of the placement frame 7 away from the bottom wall of the mounting groove 11. There are four positioning baffles 71, and the four positioning baffles 71 are enclosed into a rectangular shape, and two adjacent positioning baffles 71 are not connected to each other. The liquid crystal panel 3 is placed in the rectangle enclosed by the four positioning baffles 71. The four positioning baffles 71 that are not connected to each other are set, so that it is not easy to damage the corners of the liquid crystal panel 3 during subsequent use.

[0052] At the same time, in order to further improve the impact on the liquid crystal panel 3 during installation and use, a buffer pad 72 is provided on the side where the placement frame 7 and the front frame 2 are close to each other, and an annular groove 721 corresponding to the liquid crystal panel 3 is opened on the side where the two buffer pads 72 are close to each other. The liquid crystal panel 3 is embedded in the annular groove 721, and the two buffer pads 72 clamp the liquid crystal panel 3. The buffer pad 72 close to the side of the placement frame 7 is embedded in a rectangle enclosed by the positioning baffle 71. The buffer pad 72 reduces the impact and vibration on the liquid crystal panel 3 and protects the integrity and safety of the liquid crystal panel 3.

[0053] During installation, the technician places a buffer pad 72 into the rectangle enclosed by the positioning baffle 71. At this time, the top of the annular groove 721 is an open end. The LCD panel 3 is placed in the annular groove 721, and then another buffer pad 72 is installed on the end of the front frame 2 close to the bottom shell 1. The front frame 2 is then inserted into the installation groove 11 so that the buffer pad 72 clamps the LCD panel 3. Finally, the technician drives the fixing block 12 to slide in the direction close to the fixing foot 21 to achieve the installation and fixation of the bottom shell 1, the front frame 2 and the LCD panel 3.

[0054] Furthermore, when the size of the liquid crystal panel is small, in order to increase the operating space when the technicians install the buffer pad 72 and the liquid crystal panel 3, it is easy for the technicians to install and help improve the installation accuracy. Figure 5 and Figure 6 A plurality of positioning sleeves 73 are fixed to one end of the placement frame 7 close to the bottom wall of the mounting groove 11, and the plurality of positioning sleeves 73 are evenly spaced along the side of the placement frame 7. Positioning pins 74 corresponding to the plurality of positioning sleeves 73 are fixed to the bottom shell 1. The plurality of positioning sleeves 73 correspond to the plurality of positioning pins 74 one by one. The positioning sleeves 73 are slidably fitted with the positioning pins 74, and the positioning pins 74 are movably inserted into the positioning sleeves 73 along the height direction of the bottom shell 1. In the present application, the number of positioning sleeves 73 and the number of positioning pins 74 are both set to eight.

[0055] During installation, the technician places the placement frame 7 together with the positioning baffle 71 installed on the placement frame 7, a buffer pad 72 and the LCD panel 3 into the installation groove 11, and at the same time aligns the positioning pin 74 and the positioning sleeve 73, and inserts the positioning pin 74 into the positioning sleeve 73 to achieve the installation of the LCD panel 3 and the bottom shell 1.

[0056] The implementation principle of the liquid crystal panel installation structure of the embodiment of the present application is as follows: during installation, the technician puts a buffer pad 72 into the rectangle enclosed by the positioning block bar 71, and then places the liquid crystal panel 3 in the annular groove 721, and at the same time installs another buffer pad 72 on the front frame 2, and then inserts the front frame 2 into the installation groove 11, and then the technician pushes the top rod 441 and the guide column 442. Since the guide column 442 and the guide hole 443 are slidably adapted, the guide column 442 drives the rotating cylinder 41 to reverse, and the rotating cylinder 41 drives the connecting rod 42 to rotate around the rotation center of the rotating cylinder 41, and the connecting rod 42 drives the fixing block 1 2 slides in the limiting hole 431 toward the direction close to the fixing foot 21, the fixing block 12 is tightly pressed against the inclined surface of the fixing foot 21, and one end of the fixing foot 21 close to the bottom wall of the installation groove 11 is tightly fitted with the bottom wall of the receiving groove 14, so that the fixing foot 21 is not easy to move away from the bottom shell 1, thereby fixing the front frame 2 and the bottom shell 1, and clamping the liquid crystal panel 3 between the bottom shell 1 and the front frame 2. At the same time, the spring 63 drives the stop pin 61 to insert into the stop groove 62, so that the push rod 441 and the bottom shell 1 maintain a constant relative position, thereby fixing the front frame 2 and the bottom shell 1, and clamping the liquid crystal panel 3 between the bottom shell 1 and the front frame 2;

[0057] During disassembly, the technician moves the shift block 64 to release the restriction on the sliding of the top rod 441. At this time, the torsion spring 444 makes the rotating cylinder 41 rotate forward, and the rotating cylinder 41 drives the guide column 442 to slide in the direction away from the bottom shell 1, and at the same time drives the connecting rod 42 to rotate around the rotation center of the rotating cylinder 41. The connecting rod 42 drives the fixed block 12 to slide in the limiting hole 431 in the direction away from the fixed foot 21. The inclined surfaces of the fixed block 12 and the fixed foot 21 are disengaged from each other, and the technician takes the front frame 2 out of the mounting groove 11, thereby disassembling the front frame 2 and the bottom shell 1.

[0058] The embodiment of the present application discloses another liquid crystal panel installation structure. Example

[0059] Reference Figure 7The difference between the embodiment of the present application and implementation 1 is that: the locking member 6 includes a top screw 67 rotatably connected to the bottom shell 1, the top screw 67 is coaxially arranged with the rotating hole 13, the rotation axis of the top screw 67 coincides with the rotation axis of the rotating cylinder 41, and the end of the top screw 67 close to the bottom shell 1 abuts against the end of the top rod 441 away from the bottom shell 1. The technician can push the top rod 441 by twisting the top screw 67. At the same time, the top screw 67 is threadedly connected to the inner wall of the rotating hole 13. The relative position of the top rod 441 and the bottom shell 1 is kept constant through the self-locking of the thread, which is convenient for the technician to operate, and the top screw 67 is not easy to cause accidental touch, affecting the stability of the fixation of the front frame 2 and the bottom shell 1.

[0060] The implementation principle of a liquid crystal panel installation structure in Example 2 of the present application is as follows: during installation, the technician screws the top screw 67 so that the top screw 67 drives the top rod 441 to slide toward the inside of the bottom shell 1, so that the fixing block 12 slides toward the fixing foot 21. At this time, the top screw 67 realizes the constant relative position of the top rod 441 and the bottom shell 1 through thread self-locking;

[0061] During disassembly, the technician twists the top screw 67 to move the top screw 67 away from the top rod 441. At this time, there is a movable space between the top rod 441 and the top screw 67, and the torsion spring 444 causes the rotating cylinder 41 to rotate forward, so that the fixed block 12 slides away from the fixed foot 21.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
