[0002] With the development of LCD technology, the size of LCD panels has become more diverse. Currently, there are many different specifications of LCD panels on the market. In the LCD manufacturing industry, in order to facilitate the handling or storage of LCD panels, both semi-finished and finished LCD panels need to be packaged and transported in boxes.

[0003] In the prior art, patent CN217101274U discloses a packaging foam plastic structure for liquid crystal panels. This structure comprises a rigid foam box body, a sliding groove, a clamping assembly, a sliding mounting block, a sliding groove, a clamping spring, a sliding block, a connecting block, a clamping plate, a protective plate, a limiting device, a first fixing plate, a first sleeve, a first support column, a first spring mounting plate, a limiting spring, a second sleeve, a second support column, a second spring mounting plate, and a second fixing plate. The protective plate provides comprehensive protection for the liquid crystal panel. During use, the liquid crystal panel is placed between two clamping plates to limit its movement and prevent it from colliding with other parts of the panel. During transportation, multiple rigid foam boxes are stacked. When bumps occur, the outermost stacked rigid foam boxes are prone to sliding and collapsing. Some are secured with ropes, but if the ropes are too tight, they can damage the rigid foam boxes; if they are too loose, they cannot effectively secure them. Furthermore, when multiple rigid foam boxes are stacked, the bottommost box bears significant pressure, which can affect the bottom LCD panel and make it inconvenient to use. To address the shortcomings of the existing technology, this utility model discloses a liquid crystal panel transportation packaging structure to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figures 1-7 The liquid crystal panel transport packaging structure shown includes a rigid foam box body 1 and a clamping assembly. A bottom plate 2 is installed at the bottom of the rigid foam box body 1, and a movable support limiting mechanism is provided on the bottom plate 2.

[0027] The movable support limiting mechanism includes two sliding grooves on the top of the base plate 2. Two sliding rods 3 are installed on the inner walls of the two sliding grooves. A slider 4 is slidably sleeved on each pair of matching sliding rods 3. A fixing block 5 is installed on the top of each slider 4. A support block 6 is installed on the bottom of each fixing block 5. Two fixing grooves are opened on the top of each fixing block 5. Two fixing rods 7 are installed on the inner walls of the four fixing grooves. An L-shaped locking block 8 is slidably sleeved on each pair of matching fixing rods 7. Four movable grooves are opened on the bottom of the base plate 2. The inner walls of the sides of the four movable grooves are provided with locking grooves. A pulling unit is provided on the base plate 2 to move the two sliders 4 and the four L-shaped locking blocks 8.

[0028] Using the above structure, during transportation, the LCD panel is first placed inside the rigid foam box 1 and fixed by the clamp assembly. Once fixed, the slider 4 is moved by the pulling unit and the sliding rod 3. The movement of the slider 4 causes the fixing block 5 to move, which in turn causes the L-shaped locking block 8 to move via the fixing rod 7. Then, the pulling unit moves the two L-shaped locking blocks 8. When the L-shaped locking block 8 aligns with the movable groove of the bottom plate 2 on another rigid foam box 1, it is placed on the two fixing blocks 5. At this time, the slider 4, fixing block 5, and support block 6 provide support, and the L-shaped locking block 8 is in the movable groove. Then, the pulling unit moves the L-shaped locking block 8. The unit allows the L-shaped card block 8 to enter the card slot. When the L-shaped card block 8 enters the card slot, it limits the bottom plate 2 on another rigid foam box 1, thereby supporting and limiting the bottom plates 2 on rigid foam boxes 1 of different sizes. This prevents the stacked rigid foam boxes 1 from sliding and collapsing during transportation. When stacked, the stress point of the upper rigid foam box 1 is on the lower bottom plate 2, preventing the bottom rigid foam box 1 from being subjected to excessive force and affecting the LCD panel. At the same time, the slider 4, fixing block 5 and support block 6 provide a certain degree of protection, reducing the impact that could damage the rigid foam box 1.

[0029] like Figures 2-7 As shown, the pulling unit includes first pull ropes 10 respectively installed on the sides of four L-shaped blocks 8. The top of the base plate 2 has four rope holes adapted to the first pull ropes 10. A movable cavity is formed on the base plate 2, and a winding rod 11 is rotatably mounted on the inner wall of the movable cavity. The other ends of the four first pull ropes 10 are all installed on the winding rod 11. One end of the winding rod 11 extends outside the base plate 2 and is equipped with a first knob 12. Second pull ropes 13 are installed on the sides of the two sliders 4. The inner walls of the sides of the two slides have clearance holes adapted to the second pull ropes 13. The movable cavity... A movable rod 14 is rotatably mounted on the inner side wall of the device. A take-up roller 15 is mounted on one end of the movable rod 14. The other ends of the two second pull ropes 13 are mounted on the take-up roller 15. The other end of the movable rod 14 extends to the outside of the base plate 2 and is equipped with a second knob 16. Elastic elements are provided on the sides of the two sliders 4 and the four L-shaped blocks 8. The advantage of this arrangement is that the sliders 4 and L-shaped blocks 8 can be moved easily by the arrangement of the first pull rope 10, the take-up rod 11, the first knob 12, the second pull rope 13, the movable rod 14, the take-up roller 15, and the second knob 16.

[0030] Specifically, turning the first knob 12 causes the winding rod 11 to rotate, which in turn winds up the first pull rope 10. The winding of the first pull rope 10 further pulls the L-shaped locking block 8, causing the two L-shaped locking blocks 8 to move closer together. Turning the second knob 16 causes the movable rod 14 to rotate, which in turn causes the winding roller 15 to rotate. The rotation of the winding roller 15 winds up the second pull rope 13, which in turn pulls the slider 4, causing the two sliders 4 to move closer together, thereby supporting and limiting the base plates 2 of different sizes.

[0031] like Figure 4 and Figure 7 As shown, the elastic element includes a second spring 19 installed on the side of the slider 4, and the other end of the second spring 19 is installed on the inner wall of the side of the slide groove. A first spring 9 is installed on the side of the L-shaped block 8, and the other end of the first spring 9 is installed on the inner wall of the side of the fixing groove. The advantage of this arrangement is that, through the arrangement of the first spring 9 and the second spring 19, when the first pull rope 10 and the second pull rope 13 do not pull the L-shaped block 8 and the slider 4, the L-shaped block 8 and the slider 4 are reset under the action of the first spring 9 and the second spring 19.

[0032] like Figure 6 As shown, a threaded hole is provided on the side of the base plate 2, and a bolt 17 is threaded onto the threaded hole. A retaining plate 18 is fitted onto the bolt 17. The retaining plate 18 abuts against the first knob 12 and the second knob 16. The advantage of this arrangement is that the bolt 17 and the retaining plate 18 make it easy to fix the first knob 12 and the second knob 16.

[0033] Specifically, the rotation of bolt 17 will cause the clamping plate 18 to move through the threaded hole. The movement of clamping plate 18 will press against the first knob 12 and the second knob 16, thereby preventing the slider 4 and the L-shaped clamping block 8 from resetting.

[0034] like Figure 4 As shown, limiting rings 20 adapted to the first pull rope 10 are installed on the sides of the two sliders 4, the bottom of the two fixing blocks 5, and the sides of the two support blocks 6. The advantage of this setting is that the limiting rings 20 can be used to limit the first pull rope 10 and prevent the first pull rope 10 from affecting the movement of the sliders 4 and fixing blocks 5.

[0035] like Figure 1 and Figure 2 As shown, two limiting grooves 21 are provided on the side of the base plate 2, and two limiting rods 22 that are compatible with the limiting grooves 21 are installed on the other side of the base plate 2. The advantage of this setting is that the limiting grooves 21 and the limiting rods 22 make it easier to connect the two base plates 2, thereby making them more stable when placed.

[0036] like Figure 3and Figure 4 As shown, the bottom of the base plate 2 has an installation groove, on which a moisture-proof plate 23 is installed. The bottoms of the two sliders 4 and the two support blocks 6 are all equipped with ball bearings. The advantage of this arrangement is that the moisture-proof plate 23 provides a certain degree of moisture protection, reducing the impact of moisture on the bottom of the rigid foam box 1 during transportation. The ball bearings facilitate the movement of the sliders 4 and the support blocks 6.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
