A splicing connection structure for a display screen and a flexible LED display screen

Abstract

This invention provides a splicing connection structure for a display screen and a flexible LED display screen, relating to the field of display screen technology. The splicing connection structure includes a frame and an extrusion head. A first display screen is disposed in the center of the frame, and two second display screens are slidably connected to the back of the first display screen. A bidirectional threaded rod is rotatably connected inside the frame, and threaded blocks are threadedly connected to both outer walls of the bidirectional threaded rod. A pop-out mechanism is fixedly connected to the front of each threaded block, and the pop-out ends of the pop-out mechanism are respectively fixedly connected to the second display screens. By rotating the handle, the bidirectional threaded rod rotates, thereby causing the two threaded blocks to move towards each other, causing the two second display screens to move outward. As the two second display screens move outward, the extrusion head comes into contact with the pop-out mechanism. Under the action of the pop-out mechanism, the extrusion head moves the second display screens outward, thus forming a perfect splice with the first display screen.

Description

Technical Field

[0001] This invention relates to the field of display screen technology, specifically to a splicing connection structure for a display screen and a flexible LED display screen. Background Technology

[0002] A display screen is a tool that displays electronic files on a screen through a specific transmission device and then reflects them to the human eye. Depending on the manufacturing materials, it can be divided into: cathode ray tube displays (CRT), plasma displays (PDP), liquid crystal displays (LCD), etc. With the continuous development of LED technology, LED displays are gradually being applied to various industries. Generally, the splicing structure of display screens on the market is mostly used for splicing flat screens.

[0003] Due to varying needs for displays, splicing displays is required in specific scenarios. However, existing splicing connection structures for displays have certain shortcomings in use. The existing technology simply uses screws to fix the splicing connection structure, which results in long splicing times and inconvenient adjustments when splicing is not needed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a splicing connection structure for a display screen and a flexible LED display screen, solving the problem of inconvenient adjustment during splicing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a splicing connection structure for a display screen, comprising a frame, wherein a first display screen is disposed in the middle of the frame, and two second display screens are slidably connected to the back of the first display screen;

[0008] The frame is internally rotatably connected to a bidirectional threaded rod, and threaded blocks are threadedly connected to both outer walls of the bidirectional threaded rod. A pop-out mechanism is fixedly connected to the front of the threaded blocks, and the pop-out end of the pop-out mechanism is fixedly connected to the second display screen.

[0009] Preferably, the surface area of ​​each of the second displays is half that of the first display, and the two second displays are symmetrically arranged on the back of the first display.

[0010] Preferably, the backs of both threaded blocks are slidably connected to the rear inner wall of the frame via sliders.

[0011] Preferably, the right end of the bidirectional threaded rod extends through to the outside of the frame and is fixedly connected to a throttle handle.

[0012] Preferably, the pop-out mechanism includes a fixed barrel, a first spring is fixedly connected to the inner bottom wall of the fixed barrel, a first piston is fixedly connected to the end of the first spring away from the fixed barrel, a guide rod is fixedly connected to the outer surface of the first piston, and the end of the guide rod away from the first piston slides through to the outside of the fixed barrel and is fixedly connected to the second display screen.

[0017] (III) Beneficial Effects

[0018] This invention provides a splicing connection structure for a display screen and a flexible LED display screen. It possesses the following features:

[0019] Beneficial effects:

[0020] 1. The device is equipped with a frame, a first display screen, two second display screens, a bidirectional threaded rod, threaded blocks, and a throttle. By rotating the throttle, the bidirectional threaded rod is rotated, which in turn causes the two threaded blocks to move in opposite directions. This allows the two second display screens to be unfolded to form a large screen when the screen needs to be expanded.

[0021] 2. An ejection mechanism is provided, which includes a fixed barrel, a first spring, a first piston, a guide rod, and a telescopic mechanism. As the two second displays move outward, the extrusion head will come into contact with the telescopic mechanism, thereby retracting the telescopic mechanism into the fixed barrel. Under the elastic force of the first spring, the guide rod will be ejected, causing it to move the second displays outward, thus forming a perfect splice with the first display.

[0022] 3. It is equipped with a telescopic mechanism. Under the action of the second spring and the second piston, when the extrusion head touches the clamping head, the clamping head can be retracted to complete the rebound. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figure 1-3 As shown, this embodiment of the invention provides a splicing connection structure for a display screen and a flexible LED display screen, including a frame 1 and an extrusion head 7. A first display screen 2 is disposed in the middle of the frame 1. Two second display screens 3 are slidably connected to the back of the first display screen 2. The surface area of ​​each of the second display screens 3 is half that of the first display screen 2. The two second display screens 3 are symmetrically disposed on the back of the first display screen 2. Two extrusion heads 7 are disposed and are respectively fixedly connected to the inner walls of the two sides of the frame 1.

[0034] The frame 1 is internally connected to a bidirectional threaded rod 4. The right end of the bidirectional threaded rod 4 extends through to the outside of the frame 1 and is fixedly connected to a handle 8. Both sides of the outer wall of the bidirectional threaded rod 4 are threadedly connected to threaded blocks 5. The back of the two threaded blocks 5 are slidably connected to the rear inner wall of the frame 1 through a slider, which limits the sliding of the two threaded blocks 5 and prevents them from rotating. The front of the threaded blocks 5 is fixedly connected to a pop-out mechanism 6. The pop-out end of the pop-out mechanism 6 is fixedly connected to the second display screen 3. When the pop-out mechanism 6 is subjected to the action of the squeezing head 7, it will achieve the pop-out effect, that is, drive the second display screen 3 forward.

[0035] The above structure, by rotating the handle 8, drives the bidirectional threaded rod 4 to rotate, which in turn drives the two threaded blocks 5 to move towards each other, causing the two second display screens 3 to move outward. As the two second display screens 3 move outward, the extrusion head 7 will come into contact with the pop-up mechanism 6, which will achieve the pop-up effect, that is, drive the two second display screens 3 to move forward, so that they can be perfectly spliced ​​with the first display screen 2. This means that when it is necessary to expand the screen, the two second display screens 3 can be unfolded to form a large screen with the first display screen 2.

[0036] The present invention also provides a flexible LED display screen, which includes the splicing connection structure of the display screens described in any of the above claims.

[0037] Example 2:

[0038] like Figure 1-6 As shown, this embodiment of the invention provides a splicing connection structure for a display screen and a flexible LED display screen, including a frame 1, a first display screen 2 disposed in the middle of the frame 1, and two second display screens 3 slidably connected to the back of the first display screen 2. The surface area of ​​each of the second display screens 3 is half that of the first display screen 2, and the two second display screens 3 are symmetrically disposed on the back of the first display screen 2.

[0039] The frame 1 is internally connected to a bidirectional threaded rod 4. The right end of the bidirectional threaded rod 4 extends to the outside of the frame 1 and is fixedly connected to a handle 8. Threaded blocks 5 are threadedly connected to the outer walls of both sides of the bidirectional threaded rod 4. The backs of the two threaded blocks 5 are slidably connected to the rear inner wall of the frame 1 via sliders, which limit the sliding of the two threaded blocks 5 and prevent them from rotating. A pop-out mechanism 6 is fixedly connected to the front of the threaded blocks 5. The pop-out ends of the pop-out mechanism 6 are fixedly connected to the second display screen 3. Specifically, the pop-out mechanism 6 includes a fixed barrel 61. A first spring 62 is fixedly connected to the inner bottom wall of the fixed barrel 61. A first piston 63 is fixedly connected to the end of the first spring 62 away from the fixed barrel 61. A telescopic mechanism 65 is embedded inside the first piston 63. A guide rod 64 is fixedly connected to the outer surface of the first piston 63. The end of the guide rod 64 away from the first piston 63 slides through to the outside of the fixed barrel 61 and is fixedly connected to the second display screen 3. In addition, extrusion heads 7 are fixedly connected to the inner walls of both sides of the frame 1.

[0040] The above structure, by rotating the handle 8, drives the bidirectional threaded rod 4 to rotate, which in turn drives the two threaded blocks 5 to move towards each other, causing the two second display screens 3 to move outward. As the two second display screens 3 move outward, the extrusion head 7 will come into contact with the telescopic mechanism 65 of the ejection mechanism 6, causing the first piston 63 to break free from its constraint. Under the elastic force of the first spring 62, the guide rod 64 will be ejected, causing it to move the second display screen 3 forward, thus forming a perfect splice with the first display screen 2.

[0041] Secondly, the telescopic mechanism 65 includes a sleeve 651, which is fixedly embedded inside the first piston 63. A second spring 652 is fixedly connected to the inner wall of the sleeve 651. A second piston 653 is fixedly connected to the end of the second spring 652 away from the sleeve 651. A locking head 654 is fixedly connected to the outer surface of the second piston 653. The end of the locking head 654 away from the second piston 653 slides through to the outside of the sleeve 651 and extends to the outside of the fixed barrel 61. Furthermore, the pressing head 7 is opposite to the locking head 654.

[0042] In the above structure, during the contact process between the extrusion head 7 and the telescopic mechanism 65, the extrusion head 7 contacts and squeezes the clamp head 654, causing the clamp head 654 and the second piston 653 to move inward, compressing the second spring 652, so that the clamp head 654 retracts into the fixed barrel 61, completing the rebound.

[0043] The present invention also provides a flexible LED display screen, which includes the splicing connection structure of the display screens described in any of the above claims.

[0044] Working principle: When the screen needs to be expanded, turn the handle 8 to drive the bidirectional threaded rod 4 to rotate, which in turn drives the two threaded blocks 5 to move towards each other, causing the two second display screens 3 to move outward. As the two second display screens 3 move outward, the pressing head 7 will come into contact with and press the clamp head 654, causing the clamp head 654 and the second piston 653 to move inward, compressing the second spring 652, causing the clamp head 654 to retract into the fixed barrel 61. At this time, under the action of the first spring 62, the guide rod 64 will pop out, causing it to move the second display screen 3 forward, so that it can be perfectly spliced ​​with the first display screen 2.

[0045] When it is necessary to retract the two second displays 3, simply press the two second displays 3 inward. When the two second displays 3 are misaligned with the first display 2, reverse the handle 8. As long as the two second displays 3 are close to each other, you can release the press. At this time, the locking head 654 will pop out the fixing barrel 61 again (the squeezing head 7 moves away from the locking head 654) to lock the second displays 3.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
