It has good practical effects and is worthy of promotion and use in the existing market.

[0004] However, the existing technology has the following shortcomings:

[0005] In the above-mentioned comparative document, the gasket and the heat sink are connected to the latch rod in the outer frame of the display screen through the connecting ears on both sides. After the two are connected, a nut is set, and the nut is manually rotated to be sleeved on the outer end of the latch rod, so that the nut is limited to the connecting ear. During this process, the staff needs to rotate and install the nuts one by one, which is more cumbersome, and the connection of the thread is easy to loosen after long-term use. Summary of the Invention

There are two groups of moving parts, which are located on the left and right sides of the outer frame respectively. The left moving rod is fixedly connected to the left side of the left moving block, and the right moving rod is fixed to the right side of the right moving block. The outer side surface of the moving rod extends to the outside of the outer frame. The push rod is fixed to the top and bottom ends of the outer side surface of the moving rod. There are four groups of connecting parts, which are located above and below the middle position of the left and right sides of the outer frame respectively. There are four groups of rotating parts, which are located above and below the left and right sides of the outer frame respectively.

The back shell is plugged into the rear side of the outer frame. The gasket is located between the display screen and the heat sink. The heat sink dissipates heat from the display screen, and the gasket provides space for the heat sink.

[0020] As a further solution of the present invention: the moving member further includes a movable rod, a limiting frame, and a limiting block;

[0021] The outer end of the moving rod is movably connected to the movable rod, the limiting frame is sleeved on the middle section of the moving rod, and the limiting block is fixed to the outer end of the movable rod;

[0023] Protective covers are clamped on both sides of the outer frame, and the protective covers are provided with clamping slots at corresponding positions of the outer frame and the rear shell.

[0024] By setting a moving part, the limit block can be linked to the outer end of the latch rod and the gasket and the heat sink are sleeved on the outer end of the latch rod. Then, the movable rod is pushed by hand to make the movable rod rotate between the inner sides through the movable axis. Then, the heat sink is pushed by hand so that the thrust of pushing the heat sink pushes the inner movable block to move inward on the latch rod, so that the movable block drives the limit block to move through the movable rod and the movable rod, thereby making the limit block sleeved on the outer end of the latch rod. The limit block can limit the inner heat sink. When the other components are linked together, the protective cover is clamped with the slot so that the protective cover protects the inner components.

[0025] As a further solution of the present invention: the connecting member further includes a set of slide grooves, a set of sliding frames, and a connecting rod;

[0027] A groove is provided on one side of the connecting rod.

[0028] By setting up connecting parts, other parts can be driven to move together. There are four groups of connecting parts, which are located above and below the middle position of the left and right sides of the outer frame respectively. The groove is opened on the rear side of the connecting rod. When the movable rod moves to the front side, the upper push rod will touch the rear side of the connecting rod, so that the push rod and the groove are engaged, so that the moving push rod pushes the connecting rod to move, and the connecting rod moves to the front side through the sliding frame. At this time, the inner end of the sliding frame moves in the slide groove.

[0029] As a further solution of the present invention: the rotating member further includes a connecting rope, a mounting rod, and an L-shaped rod;

[0030] The connecting wheel is sleeved on the surface of the mounting rod, one end of the mounting rod is fixedly connected to the outer frame, the connecting rope is wound around the surface of the connecting wheel, and the L-shaped rod is fixed to one end above the connecting rope;

[0031] The other end of the connecting rope is fixedly connected to the top of the connecting rod, and a fixing frame is sleeved on the surface of one end of the L-shaped rod and above the connecting rope, and the inner end of the fixing frame is fixedly connected to both sides of the outer frame.

[0032] By setting a rotating part, the sealing strip after clamping can be further limited. There are four groups of rotating parts, which are respectively located above and below the left and right sides of the outer frame. The right end of the left mounting rod is fixedly connected to the left side of the outer frame, and the left end of the right mounting rod is fixedly connected to the right side of the outer frame. The L-shaped rod is fixed to the front end above the connecting rope, and the front end below the connecting rope is fixedly connected to the top of the connecting rod. The connection method of the lower connecting piece is opposite to that of the upper connecting piece. The fixing frame is sleeved on the rear end of the L-shaped rod and the front side of the upper connecting rope, and the inner end of the fixing frame is fixedly connected to the left and right sides of the outer frame.

[0033] When the connecting rod moves forward, the connecting rod drives the L-shaped rod to move through the connecting rope, and the connecting rope is wrapped around the surface of the connecting wheel. When the connecting rod moves forward, the connecting rope drives the L-shaped rod and the clamping plate to move backward through the connecting wheel, so that the clamping plate limits the sealing strip in one step.

[0034] As a further solution of the present invention: the limiting member further includes a group of abutments, a group of limiting rods, and a group of round rods;

[0035] One end of the fixed plate is fixed to both sides of one end of the outer frame, the stop block is fixed to the upper and lower ends of the limit block, the limit rods are passed through the top and bottom ends of the fixed plate, the round rod is sleeved inside the limit rod, and both ends of the round rod extend to the outside;

[0036] One end of the round rod is fixedly connected to a movable block, and the other end is fixedly connected to a limiting ring. The outer side of the movable block is fixedly connected to an external block, and placement grooves are opened at the edges of both ends of one side of the rear shell.

[0037] By setting a limit piece, the limit block after being sleeved with the latch rod can be resisted and limited. There are two groups of limit pieces, which are respectively located at the left and right edges of the rear end of the outer frame, and each group is located above and below the notch. The front end of the fixed plate is fixedly connected to the rear side of the outer frame, and the upper and lower ends of the round rod extend to the outside of the limit rod. The movable block is fixed to the inner end of the round rod, and the outer end of the round rod is fixedly connected to the limit ring. A placement groove is opened in the middle position of the left and right edges of the front end of the rear shell, and the placement groove is clamped with the limit piece;

[0038] When the movable rod is pushed, the movable rod drives the limit block to rotate toward the inside of the outer frame through the movable axis. When the limit block rotates, the resisting blocks at the upper and lower ends conflict with the external block. When the moving rod drives the limit block to move, the resisting block pushes the external block to drive the movable block to move upward and downward, so that the movable blocks are separated, the limit block enters the slot, and is socketed with the rear end of the latch rod.

[0039] As a further solution of the present invention: a spring is sleeved on the surface of the round rod, one end of the spring is fixedly connected to the limit rod, and the other end is fixedly connected to the round rod;

[0040] A shift rod is fixedly connected to the inner side of the movable block.

[0041] When the external block moves, it drives the movable block to move, and the movable block moves outward through the round rod above or below. When the limit block enters the slot, the force resisting the movable block disappears, and the spring drives the round rod to pop out, and the round rod drives the movable block to move to its original position. At the same time, the gear lever on the inside of the movable block presses the rear side of the limit block to prevent the limit block from detaching from the latch rod.

[0042] As a further solution of the present invention: the outer end of the L-shaped rod is fixedly connected to a clamping plate, the outer side of the clamping plate is fixedly connected to a plug rod, and the plug rod passes through the clamping plate, and one end of the plug rod extends to the inside of the connection between the sealing strip and the outer frame;

[0043] The L-shaped rod is provided with a hole at a corresponding position on one side of the protective cover.

[0044] By setting a clamping plate, the sealing strip can be limited after clamping to prevent loosening. The clamping plate is fixed to the front end of the L-shaped rod, and the rear end of the plug-in rod passes through the sealing strip and extends to the connection between the sealing strip and the outer frame. The hole is opened on the front side of the protective cover; when the L-shaped rod moves toward the rear side, it will drive the clamping plate and the plug-in rod to move toward the rear side, so that the clamping plate and the plug-in rod are inserted into the outer frame, so that the clamping plate and the plug-in rod limit the sealing strip.

[0045] As a further solution of the present invention: the snap-in plate is provided with a snap-in groove at a corresponding position of the outer frame, the interior of the snap-in groove is magnetic, and the snap-in groove and the snap-in plate are attracted to each other.

[0046] When the L-shaped rod drives the connecting plate and the plug rod to move backward, the connecting plate is inserted into the connecting groove, the plug rod is inserted into the outer frame, and the connecting plate and the connecting groove are adsorbed, so that the connecting plate can better limit the sealing strip.

[0047] A packaging method for a packaging structure for producing an LED display screen, comprising:

[0048] S1. During assembly, slide the display screen from the back of the outer frame to the inside of the outer frame, and align the display screen with the opening on the front of the outer frame to display. Then, connect the gasket and the heat sink's connecting ear sleeve to the latch rod. Then, push the movable rod by hand, so that the movable rod drives the limit block to rotate inward, and then push the heat sink;

[0049] S2. The thrust of pushing the heat sink pushes the moving block on the latch rod, so that the moving block drives the moving rod to move in the moving groove, so that the moving rod drives the limit block to engage with the outer end of the latch rod, so that the limit block limits the gasket and the heat sink after the engagement;

[0050] S3. When the moving rod moves, it drives the push rod to move, so that the push rod touches the connecting rod, and the push rod drives the connecting rod to move. The connecting rod drives the clamping plate to move through the connecting rope and the connecting wheel, so that the clamping plate is clamped with the clamping groove, and the plug-in rod enters the interior of the sealing strip, so that the clamping plate and the plug-in rod further limit the clamped sealing strip to prevent the clamping joint from loosening;

[0051] S4. When the moving rod drives the movable rod and the limit block to move, the upper and lower blocks of the limit block touch the external block, so that the moving blocks squeeze the external block upward and downward. The external block drives the movable block to move upward and downward through the round rod and the spring, so that the limit block enters the slot, and the limit block is socketed with the latch rod. After socketing, the inner gear rod presses the limit block to prevent the limit block from loosening, and then the rear shell is plugged into the two ends of the rear side of the outer frame to complete the fixation of the outer frame and the rear shell.

[0052] Through these steps, you can better understand the steps of using the structure.

[0053] Compared with the prior art, the present invention has the following beneficial effects:

[0054] By setting the moving block and the moving rod, manual operation can be reduced. When assembling the display screen, the gasket and the heat sink are sleeved at the rear end of the latch rod, and the movable rod flush with the moving rod is pushed. The movable rod drives the limit block to rotate toward the inside of the outer frame, and then pushes the heat sink. The thrust drives the gasket to squeeze the moving block, so that the moving block drives the moving rod to move to the front side, so that the moving rod drives the limit block to move through the movable rod, and then the limit block is sleeved at the rear end of the latch rod, so that the sleeved limit block limits the inner heat sink, so that there is no need to tighten the nuts one by one, and the steps are simplified. Only the heat sink needs to be pushed to complete the installation and fixation of the heat sink and the gasket. At the same time, after long-term use, the loosening of the connection between the limit block and the latch rod can be prevented.

[0055] Based on the first beneficial effect, when the moving rod moves, it drives the upper push rod to move. When the push rod moves to conflict with the connecting rod, the moving push rod links the connecting rod to move, so that the connecting rod drives the clamping plate and the plug-in rod to move backward through the upper connecting rope and the L-shaped rod, and then the clamping plate and the plug-in rod limit the installed sealing strip. The sealing strip and the shell are only connected by clamping. After long-term use, the clamping joint gradually loosens. Therefore, the clamping plate is inserted into the clamping groove, and the two are adsorbed. The clamping plate after clamping can limit the sealing strip, thereby preventing the loosening of the clamping joint between the sealing strip and the outer frame, and extending the service life of the sealing strip.

[0056] Based on the second beneficial effect, when the movable rod drives the limit block to rotate inward, the abutment blocks at the upper and lower ends of the limit block conflict with the external block. When the movable rod drives the movable rod and the limit block to move, the abutment blocks link the external block to drive the movable block to move upward and downward, so that the movable blocks are separated, the limit block enters the groove, and is socketed with the rear end of the pin rod. A gear rod is fixedly connected to the inner side of the movable block, and the gear rod presses the limit block to prevent the limit block from loosening and prevent the limit block from detaching from the rear end of the pin rod.

At the same time, the movable block 21 drives the movable rod 23 and the limit block 25 to move through the movable rod 22. At this time, the movable rod 22 moves in the movable groove 221, so that the limit block 25 enters the notch 17, and the limit block 25 is sleeved on the outer end of the latch rod 18, so that the sleeved limit block 25 limits the inner heat sink 16;

[0081] When the other components are operated together, the protective cover 26 is engaged with the slot 261 so that the protective cover 26 protects the components inside.

[0082] Please refer to Figures 1 to 2 、 Figures 7 to 9 , the connecting member 3 further includes a set of slide grooves 32, a set of sliding frames 33, and a connecting rod 34;

[0083] The slide grooves 32 are provided at the upper and lower middle portions of both sides of the outer frame 11 , the sliding frames 33 are slidably connected to the outer sides of the slide grooves 32 , and the connecting rods 34 are fixed between one side of the sliding frames 33 ;

[0084] A groove 35 is formed on one side of the connecting rod 34;

[0085] The rotating member 4 further includes a connecting rope 41, a mounting rod 42, and an L-shaped rod 44;

[0086] The connecting wheel 43 is sleeved on the surface of the mounting rod 42. One end of the mounting rod 42 is fixedly connected to the outer frame 11.

[0088] The outer end of the L-shaped rod 44 is fixedly connected to a clamping plate 46, and the outer side of the clamping plate 46 is fixedly connected to a plug rod 47. The plug rod 47 passes through the clamping plate 46, and one end of the plug rod 47 extends to the inside of the connection between the sealing strip 13 and the outer frame 11;

[0089] The L-shaped rod 44 defines a hole 262 at a corresponding position on one side of the protective cover 26;

[0090] The clamping plate 46 defines a clamping slot 48 at a corresponding position of the outer frame 11 . The interior of the clamping slot 48 is magnetic, and the clamping slot 48 and the clamping plate 46 are attracted to each other.

[0091] In this embodiment, when the moving rod 22 moves forward, the upper push rod 31 contacts the rear side of the connecting rod 34, causing the push rod 31 to engage with the groove 35. As a result, the moving push rod 31 pushes the connecting rod 34 to continue moving. The connecting rod 34 moves forward via the sliding frame 33. At this time, the inner end of the sliding frame 33 moves in the sliding groove 32.

[0092] When the connecting rod 34 moves forward, the connecting rope 41 is wound around the surface of the connecting wheel 43, so the connecting rod 34 drives the connecting wheel 43 to rotate via the connecting rope 41. When the connecting rod 34 moves forward, the connecting rope 41 drives the L-shaped rod 44 to move backward via the connecting wheel 43.

[0093] When the L-shaped rod 44 moves toward the rear, it will drive the clamping plate 46 and the plug-in rod 47 to move toward the rear. The clamping plate 46 is inserted into the clamping groove 48, and the clamping plate 46 and the clamping groove 48 are adsorbed. At the same time, the plug-in rod 47 is inserted into the connection between the sealing strip 13 and the outer frame 11, so that the clamping plate 46 and the plug-in rod 47 can better limit the sealing strip 13.

[0094] Please refer to Figures 1 to 2 、 Figure 7 , Figures 10 and 11 The limiting member 5 further includes a set of stop blocks 52, a set of limiting rods 54, and a set of round rods 55;

[0095] One end of the fixing plate 53 is fixed to both sides of one end of the outer frame 11, the stop block 52 is fixed to the upper and lower ends of the limit block 25, the limit rod 54 passes through the top and bottom ends of the fixing plate 53, the round rod 55 is sleeved inside the limit rod 54, and both ends of the round rod 55 extend to the outside;

[0096] One end of the round rod 55 is fixedly connected to a movable block 56, and the other end is fixedly connected to a limit ring 551. The outer side of the movable block 56 is fixedly connected to an external block 57. The edges of both ends of one side of the rear shell 14 are provided with placement grooves 51;

[0098] A shift rod 59 is fixedly connected to the inner side of the movable block 56 .

[0099] In this embodiment, when the movable rod 23 is pushed by hand, the movable rod 23 drives the limit block 25 to rotate toward the inside of the outer frame 11 through the movable shaft 222. When the limit block 25 rotates, the upper and lower end blocks 52 conflict with the external block 57. When the movable rod 22 drives the limit block 25 to move, the block 52 pushes the external block 57, and the external block 57 drives the movable block 56 to move upward and downward. At the same time, the movable block 56 moves outward through the upper or lower round rod 55. The round rod 55 slides inside the limit rod 54, thereby separating the movable block 56. At this time, the limit block 25 enters the slot 17.

[0100] When the limit block 25 enters the notch 17, the force resisting the movable block 56 disappears, the spring 58 drives the round rod 55 to pop out, and the round rod 55 drives the movable block 56 to move to its original position. At the same time, the gear lever 59 inside the movable block 56 presses the rear side of the limit block 25 to prevent the limit block 25 from separating from the latch rod 18;

[0101] Then, the rear shell 14 is snap-fitted to the rear side of the outer frame 11 , so that the placement groove 51 is snap-fitted to the limiting member 5 , and the limiting member 5 is located in the placement groove 51 .

[0102] Working principle:

[0103] S1. During assembly, slide the display screen 12 from the back of the outer frame 11 to the inside of the outer frame 11, and align the display screen 12 with the opening on the front of the outer frame 11 to display. Then, connect the connecting ears of the gasket 15 and the heat sink 16 to the latch rod 18. Then, push the movable rod 23 by hand, so that the movable rod 23 drives the limit block 25 to rotate inward, and then push the heat sink 16.

[0104] S2. The thrust when pushing the heat sink 16 pushes the moving block 21 on the latch rod 18, so that the moving block 21 drives the moving rod 22 to move in the moving groove 221, so that the moving moving rod 22 drives the limiting block 25 to engage with the outer end of the latch rod 18, so that the limiting block 25 limits the gasket 15 and the heat sink 16 after the engagement;

[0105] S3. When the moving rod 22 moves, it drives the push rod 31 to move, so that the push rod 31 touches the connecting rod 34, so that the push rod 31 drives the connecting rod 34 to move, and the connecting rod 34 drives the clamping plate 46 to move through the connecting rope 41 and the connecting wheel 43, so that the clamping plate 46 is clamped with the clamping groove 48, and the plug-in rod 47 enters the interior of the sealing strip 13, so that the clamping plate 46 and the plug-in rod 47 further limit the clamped sealing strip 13 to prevent the clamping joint from loosening;

[0106] S4. When the movable rod 22 drives the movable rod 23 and the limit block 25 to move, the upper and lower abutments 52 of the limit block 25 touch the external block 57, so that the abutment 52 squeezes the external block 57 upward and downward during movement. The external block 57 drives the movable block 56 to move upward and downward through the round rod 55 and the spring 58, so that the limit block 25 enters the slot 17, and the limit block 25 is sleeved with the latch rod 18. After the sleeve is sleeved, the inner gear rod 59 presses the limit block 25 to prevent the limit block 25 from loosening, and then the rear shell 14 is inserted into the two ends of the rear side of the outer frame 11 to complete the fixation of the outer frame 11 and the rear shell 14.

[0107] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
