Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to an LED display screen that is easy to assemble and disassemble. Background Technology

[0002] In conference rooms, a large screen is usually installed to display meeting content or broadcast videos. Traditionally, projectors are used to play videos, which is convenient as it only requires a display screen. However, this method suffers from poor overall display quality and low brightness, making the image difficult to see in sunlight or artificial light. Therefore, video wall displays are gradually replacing projectors in conference rooms. They offer higher overall resolution, are unaffected by sunlight or artificial light, and require only partial disassembly for maintenance, eliminating the need to replace the entire screen.

[0003] Existing video wall displays typically involve mounting the LED display screen onto a support frame using screws, which is inconvenient during installation and makes disassembling one of the LED displays later quite troublesome.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to design a display screen that can be quickly assembled and disassembled on a support frame without the use of screws, thereby overcoming the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easy-to-assemble and disassemble LED display screen, comprising connectors installed at the four corners of the back of the display screen, and mounting blocks fixedly installed on a support frame and matching the connectors. The mounting blocks have a cavity inside, a bottom fastener is vertically slidably connected inside the cavity, a first spring is installed at the bottom of the bottom fastener, a horizontally slidable locking component is inside the cavity, a second spring is fixedly installed on the side of the locking component away from the connectors, the bottom of the locking component is snapped to the bottom fastener, the connectors and the locking component are snapped to each other, and a third spring is fixedly installed at the top of the bottom fastener.

[0007] When the connector and the locking part are engaged, the bottom fastener is not engaged with the locking part; when the connector moves toward the bottom fastener, it will drive the locking part to engage with the bottom fastener, and the locking part will no longer engage with the connector. The third spring will push the connector out of the mounting block.

[0008] Preferably, the connector includes a connecting block that is slidably connected to the mounting block, and a buckle strip that is fixedly connected to the bottom of the connecting block. The connecting block is fixedly connected to the back of the display screen, and the bottom surface of the buckle strip contacts the third spring.

[0009] Preferably, the locking component includes an upper locking block that is snapped into the locking strip, a trapezoidal block that is fixedly connected to the bottom of the upper locking block, and a lower locking block that is fixedly connected to one side of the trapezoidal block. The lower locking block is snapped into the bottom fastener. When the connecting component contacts the trapezoidal block, it pushes the locking component to compress the second spring.

[0010] Preferably, the bottom fastener includes a snap-fit ​​rib that snaps into the lower snap-fit ​​block, and a horizontal plate that is fixedly connected to the bottom of the snap-fit ​​rib, the bottom surface of which is fixedly connected to the first spring.

[0011] Preferably, a vertical column is slidably connected through the horizontal plate, a horizontal column is slidably connected through the upper block, a baffle is fixedly connected to the end of the horizontal column, and the trapezoidal block has a receiving cavity for inserting the vertical column.

[0012] Preferably, the buckle strip has a blind hole, and a guide strip that is fixedly connected to the top surface of the cross plate is slidably connected in the blind hole.

[0013] Preferably, the spring force of the first spring is greater than that of the third spring.

[0014] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0015] 1. When installing this product, simply align the connector with the mounting block and press it down. Stop pressing when you hear a "click" sound, and the display screen will be installed on the support frame. Compared with the existing technology that uses screws and other installation methods, the installation is convenient and quick.

[0016] 2. When disassembling this product, simply press the display screen further into the mounting block until the lower clip and the snap rib are engaged. This will prevent the connector from engaging with the locking mechanism. After releasing the pressure, the third spring will push the connector out of the mounting block, allowing the user to easily remove the display screen from the support frame. The operation is convenient and the disassembly is quick. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This invention provides, for example Figure 1-4The diagram illustrates an easily detachable LED display screen 1 for mounting and dismounting from a support frame 2. It includes connectors 3 installed at the four corners of the back of the display screen 1, and mounting blocks 4 fixedly mounted on the support frame 2 and matching the connectors 3. Each connector 3 includes a connecting block 3a that slides vertically to the mounting block 4, and a snap-fit ​​strip 3b fixedly connected to the bottom of the connecting block 3a. The connecting block 3a is fixedly connected to the back of the display screen 1. The mounting block 4 has a cavity 5 inside, and a bottom fastener 6 slides vertically within the cavity 5. The bottom fastener 6 includes a snap-fit ​​rib 6a and a horizontal plate 6b fixedly connected to the bottom of the snap-fit ​​rib 6a. A first spring 7 is fixedly connected between the bottom surface of the horizontal plate 6b and the mounting block 4. The cavity 5 has a horizontally sliding locking element 8, which includes an upper locking block 8a snap-fitted to the snap-fit ​​strip 3b, and a bottom locking element 8b fixed to the upper locking block 8a. A trapezoidal block 8b is fixedly connected, and a lower locking block 8c is fixedly connected to one side of the trapezoidal block 8b. The lower locking block 8c is locked to the locking rib 6a. A second spring 9 is fixedly installed on the side of the upper locking block 8a away from the connector 3. When the connector 3 contacts the trapezoidal block 8b, it pushes the locking member 8 to compress the second spring 9. A third spring 10 is fixedly installed on the top of the bottom fastener 6. The bottom surface of the locking strip 3b contacts the third spring 10. A vertical column 11 is slidably connected through the horizontal plate 6b. A horizontal column 12 is slidably connected through the upper locking block 8a. A baffle 13 is fixedly connected to the end of the horizontal column 12. The trapezoidal block 8b has a receiving cavity 14 for the vertical column 11 to be inserted. The locking strip 3b has a blind hole 15. A guide strip 16 is slidably connected to the top surface of the horizontal plate 6b. The elastic force of the first spring 7 is greater than that of the third spring 10.

[0027] When installing the display screen 1, the user presses the connector 3 on the back of the display screen 1 against the mounting block 4. The connector 3a on the connector 3 will drive the latching strip 3b to move into the cavity 5 of the mounting block 4. When the latching strip 3b contacts the upper latching block 8a, it will drive the upper latching block 8a to compress the second spring 9. The upper latching block 8a will drive the lower latching block 8c to move. At this time, the lower latching block 8c has not yet been latched with the latching rib 6a, and the guide rod will be inserted into the blind hole 15. The latching strip 3b will compress the third spring 10. When the latching strip 3b passes through the upper latching block 8a, the second spring 9 will return to its original position, the upper latching block 8a will return to its original position, and the upper latching block 8a will collide with the baffle 13, making a "click" sound. At this time, the user will stop pressing the display screen 1, and the third spring 10 will apply elastic force to the latching strip 3b, causing the latching strip 3b to latch with the upper latching block 8a. At this time, the latching strip 3b cannot be moved out of the mounting block 4, and the installation of the display screen 1 is completed.

[0028] When it is necessary to disassemble the display screen 1, the user continues to press the display screen 1 downwards. At this time, the latching strip 3b will contact the trapezoidal block 8b, thereby pushing the trapezoidal block 8b to move towards the latching rib 6a. The trapezoidal block 8b pushes the lower latching block 8c to contact the latching rib 6a. At this time, the latching rib 6a will drive the horizontal plate 6b to move downwards, thereby compressing the first spring 7. After the lower latching block 8c passes over the latching rib 6a, the first spring 7 will drive the latching rib 6a to reset. Then the user releases the hand and stops pressing. The second spring 9 will drive the upper latching block 8a to move towards the latching strip 3b. Due to the latching rib 6a, the lower latching block 8c will be latched to the latching rib 6a, while the latching strip 3b will no longer be latched to the upper latching block 8a. At this time, the third spring 10 will drive the latching strip 3b to move out of the mounting block 4 under the action of elasticity. At this time, the user removes the screen from the support frame 2.

[0029] Finally, the user inserts a small stick that can be inserted from the outside into the guide bar 16, driving the guide bar 16 to move downward. The guide bar 16 drives the horizontal plate 6b, and the horizontal plate 6b drives the buckle rib 6a to separate from the lower buckle block 8c, which will reset the upper buckle block 8a.

[0030] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
