A double-sided liquid crystal screen structure

Abstract

This utility model discloses a double-sided LCD screen structure, including an outer frame with a support base at the bottom. A pair of LCD screens are symmetrically mounted inside the outer frame via an installation mechanism. The installation mechanism includes a pair of symmetrically sliding mating plates within the outer frame, with a locking plate on the opposite side of each mating plate. An installation plate is located on the back of each LCD screen. Vertical movement is converted to horizontal movement via an inclined sliding groove. The LCD screen moves horizontally along the outer frame's sliding rail, eliminating the need for excessive operating space in the screen's thickness direction. Even with a certain screen thickness, the mating plates provide ample space for alignment, pushing, and separation, improving the ease of installation and disassembly. Simultaneously, the adjusting wheels can be retracted into a reinforced frame, effectively preventing accidental external contact that could lead to unintended movement of the LCD screen. This ensures screen stability during use and when not in use, reducing the risk of unexpected malfunctions.

Description

Technical Field

[0001] This utility model relates to the field of LCD screen technology, specifically a double-sided LCD screen structure. Background Technology

[0002] To improve the display effect, current displays typically adopt a double-sided LCD screen structure, which consists of two frames joined together and two LCD screens mounted on the two frames respectively.

[0003] A search revealed a patent with publication number CN221323951U, which proposes a double-sided LCD screen structure, including a main frame, a rotating frame, an assembly plate, and an LCD screen. The main frame has symmetrical angle adjustment mechanisms on both sides that match the rotating frame. The movable plate is first placed on the back of the LCD screen, and then a connecting bolt is screwed through the connecting hole into the reserved hole on the back of the LCD screen to fix the movable plate to the back of the LCD screen. When the outer wall of one side of the movable plate is aligned with the inside of the hook, the movable plate is inserted into it. Then, a fastening bolt is screwed into the bottom of the base to clamp the movable plate and fix it to the assembly plate. This allows the LCD screen to be installed inside the rotating frame. After completion, there are not too many screw heads exposed, which avoids affecting the aesthetics of the LCD screen.

[0004] In the aforementioned prior art, the installation method of the LCD screen is to push it flat. Since the LCD screen usually has a certain thickness, there will be insufficient hand space when installing and removing the LCD screen. Utility Model Content

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-5This utility model provides a technical solution: a double-sided LCD screen structure, including an outer frame 1 as an overall supporting frame, with a space reserved inside the outer frame 1 to accommodate the movement of the LCD screen 3, and a support base 2 fixedly installed at its bottom. The support base 2 not only provides stable support for the entire device, but also has a storage cavity inside that matches the size of the LCD screen 3, which can accommodate the retracted LCD screen 3. A pair of LCD screens 3 are symmetrically installed inside the outer frame 1 through an installation mechanism 4. The installation mechanism 4 is the core component for realizing the retraction and fixation of the LCD screens 3, ensuring that the two screens can be stably and symmetrically arranged.

[0022] The mounting mechanism 4 includes a pair of mating plates 6 symmetrically slidably mounted on a slide rail on the inner wall of the outer frame 1. The mating plates 6 can move horizontally along the slide rail. A locking plate 7 is integrally formed on the side of the mating plate 6 closest to the LCD screen 3. A mounting plate 5 is pre-fixed to the back of the LCD screen 3 by bolts. A slot adapted to the locking plate 7 is opened on one side of the mounting plate 5. The locking plate 7 can be inserted into the slot of the mounting plate 5 and slidably assembled. Through the insertion and cooperation of the two, the initial constraint between the LCD screen 3 and the mating plate 6 can be quickly completed, and the initial fixation can be achieved without complicated tools. A connecting plate 12 is vertically fixed on the side of the mating plate 6 away from the locking plate 7. A protrusion 17 is integrally formed on the outer wall of the connecting plate 12. A movable block 14 is slidably mounted in the vertical direction inside the outer frame 1. A sliding groove 16 with an inclined structure is symmetrically opened on both sides of the movable block 14. The protrusion 17 is inserted into the sliding groove 16 and slidably assembled. The inclined angle design of the sliding groove 16 can convert the vertical movement of the movable block 14 into the horizontal movement of the protrusion 17, thereby driving the mating plate 6 to move horizontally synchronously.

[0023] A reinforcing frame 8 is fixedly installed at the top of the outer frame 1. The reinforcing frame 8 is a closed frame structure used to stably support the rotating rod 11. The rotating rod 11 is vertically inserted and rotatably installed in the reinforcing frame 8 through bearings. The bottom end of the rotating rod 11 is machined with a threaded part 13. The threaded part 13 is inserted into the movable block 14 and screwed to the movable block 14. The power transmission between the rotating rod 11 and the movable block 14 is realized through threaded transmission. Guide rods 15 are symmetrically fixed at the bottom of the reinforcing frame 8. The guide rods 15 are inserted into the movable block 14 and slidably assembled. The guide rods 15 can limit the rotation of the movable block 14, ensuring that when the rotating rod 11 rotates, the movable block 14 moves smoothly only in the vertical direction. The rotating rod 11 has a sliding hole along the axial direction inside. The insertion rod 10 is inserted into the sliding hole and slides in cooperation with the rotating rod 11. An adjusting wheel 9 is fixedly installed on the top of the insertion rod 10. The outer circumference of the adjusting wheel 9 is provided with anti-slip texture for easy gripping and rotation. Several evenly distributed limiting blocks 18 are fixed on the outer wall of the insertion rod 10. The inner wall of the sliding hole of the rotating rod 11 has a long groove that matches the limiting block 18. The limiting block 18 is inserted into the long groove and slidably installed, which can prevent the insertion rod 10 from disengaging from the rotating rod 11 and ensure that the rotating rod 11 rotates synchronously when the insertion rod 10 rotates. Pressing down on the adjusting wheel 9 can move the insertion rod 10 down along the sliding hole of the rotating rod 11 and store the adjusting wheel 9 in the reinforcing frame 8 to prevent accidental external contact.

[0024] In use, first, according to the back dimensions of the LCD screen 3, firmly fix the mounting plate 5 to the back of each LCD screen 3 with bolts, ensuring that the mounting plate 5 fits snugly against the back of the screen without any looseness. Then, move the LCD screen 3 to the openings on both sides of the outer frame 1, aligning the slot of the mounting plate 5 with the locking plate 7 on the docking plate 6, and slowly push the LCD screen 3 horizontally until the locking plate 7 is fully inserted into the slot of the mounting plate 5. At this point, the LCD screen 3 and the docking plate 6 form a stable constraint and will not easily detach. Next, the operator pulls up the adjusting wheel 9, and the insertion rod 10 moves upward along the sliding hole of the rotating rod 11. The limiting block 18 slides in the long slot until the adjusting wheel 9 extends out of the reinforcing frame 8. Hold the adjusting wheel 9 and rotate it clockwise. The adjusting wheel 9 drives the insertion rod 10 synchronously. Rotating, the insertion rod 10 drives the rotating rod 11 to rotate around the bearing inside the reinforcing frame 8 through the limiting block 18. The threaded part 13 of the rotating rod 11 is screwed to the movable block 14. Under the guidance of the guide rod 15, the rotation of the rotating rod 11 is converted into the vertical upward movement of the movable block 14. When the movable block 14 moves upward, the inclined sliding grooves 16 on both sides of it generate a horizontal inward traction force on the protrusion 17. The protrusion 17 drives the connecting plate 12 and the docking plate 6 to move horizontally towards the center of the outer frame 1. The docking plate 6 simultaneously pulls the LCD screen 3 along the slide rail of the outer frame 1 to move inward until the LCD screen 3 is completely retracted into the storage cavity of the support base 2. Stop rotating the adjusting wheel 9 and press it down to store the adjusting wheel 9 into the reinforcing frame 8. The reinforcing frame 8 blocks and prevents accidental touch, ensuring that the screen is stably stored.

[0025] When the LCD screen 3 needs to be removed for maintenance or replacement, pull out the adjusting wheel 9 upwards and rotate the adjusting wheel 9 counterclockwise. This will cause the rotating rod 11 to rotate in the opposite direction. The threaded part 13 will drive the movable block 14 to move vertically downwards along the guide rod 15. The inclined slide groove 16 of the movable block 14 will generate a horizontal outward pushing force on the protrusion 17. The protrusion 17 will drive the connecting plate 12 and the docking plate 6 to move outwards. The docking plate 6 will push the LCD screen 3 out of the storage cavity of the support base 2 until the screen is completely extended out of the outer frame 1. Pull the LCD screen 3 horizontally to disengage the mounting plate 5 from the locking plate 7. The screen can then be removed for subsequent operations.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
