DETAILED DESCRIPTION

[0028] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0029] Reference Figure 1-Figure 4 , shows a schematic structural diagram of a mounting structure of a liquid crystal display screen, which may specifically include: a mounting frame 1 and a liquid crystal display screen 2, wherein the liquid crystal display screen 2 is fixed to the back side of the mounting frame 1, and the back side of the mounting frame 1 is connected with at least one group of positioning sliders 3 arranged opposite to each other, and the positioning sliders 3 are provided with a first slide groove 31 adapted to the mounting device on the side away from each other;

[0030] A pressing hole 11 is provided at a relative position between the mounting frame 1 and the positioning slider 3. An elastic locking component 4 for locking or unlocking with the mounting device is provided inside the positioning slider 3. One end of the elastic locking component 4 is passed through the pressing hole 11 and is flush with the pressing hole 11 on the front side of the mounting frame 1.

[0031] In the embodiment of the present application, the LCD screen 2 is fixed to the mounting frame 1, and a detachable connection is achieved between the mounting frame 1 and the mounting device, and the positioning slider 3 is used to slide the mounting device, so that the operation is simple during disassembly and assembly. By setting an elastic locking component 4 in the positioning slider 3 and setting a pressing hole 11 on the edge of the mounting frame 1, the elastic locking component 4 can be directly pressed from the pressing hole 11 during disassembly and assembly to achieve locking or unlocking, and then the LCD screen 2 and the mounting frame 1 can be disassembled and assembled as a whole; by inserting one end of the elastic locking component 4 into the pressing hole 11 and flushing with the pressing hole 11, the elastic locking component 4 will not bulge outward in a natural state, which can improve the appearance and will not affect the operation of the LCD screen 2. The present application has a simple structure, is fixed by locking, and is firmly installed, and is convenient and quick to disassemble and assemble.

[0032] Next, a mounting structure of a liquid crystal display screen 2 in this exemplary embodiment will be further described.

[0033] In one embodiment of the present application, the LCD screen 2 is fixed to the back side of the mounting frame 1, and at least one set of positioning sliders 3 are connected to the back side of the mounting frame 1, and a first slide groove 31 adapted to the mounting device is provided on the side of the positioning sliders 3 that are away from each other. The LCD screen 2 and the mounting frame 1 are assembled into an integrated structure and then installed with the mounting device. The positioning slider 3 is slidably connected with the first slide groove 31 of the mounting device. On the one hand, the mounting frame 1 can be positioned during installation under the adaptation of the positioning slider 3 and the first slide groove 31, so that quick alignment and precise installation are achieved. On the other hand, the disassembly and assembly efficiency is high and the operation is simple and fast.

[0034] A pressing hole 11 is provided at a position relative to the mounting frame 1 and the positioning slider 3. An elastic locking component 4 for locking or unlocking with the mounting device is provided in the positioning slider 3. One end of the elastic locking component 4 is passed through the pressing hole 11 and is flush with the pressing hole 11 at the front side of the mounting frame 1. By providing the elastic locking component 4 in the positioning slider 3, it is locked with the mounting device during installation, so that the mounting frame 1 and the LCD screen 2 can be firmly installed on the mounting device. By passing the elastic locking component 4 through the pressing hole 11 provided in the mounting frame 1 and being flush with the outer end surface of the hole, the elastic locking component 4 does not protrude from the pressing hole 11, that is, does not protrude from the surface of the LCD screen 2. On the one hand, it avoids affecting the operation and use of the LCD screen 2, and on the other hand, it can improve the aesthetics of the exterior of the LCD screen 2. By opening the pressing hole 11, the elastic locking component 4 is pressed to unlock. When unlocking is required, the elastic locking component 4 is pressed to move it inward. At this time, there is a certain space between the pressing hole 11 and the elastic locking component 4. When it is unlocked, the operator can hold the space to pull out the installation frame 1 and the LCD screen 2, so that the LCD screen 2 can be disassembled efficiently and quickly for easy maintenance.

[0035] As an example, a mounting groove 12 is provided on the back side of the mounting frame 1, a first magnetic strip is embedded in the edge of the mounting groove 12, a connecting portion 21 adapted to the mounting groove 12 is provided on the edge of the LCD screen 2, a second magnetic strip is provided on the side of the connecting portion 21 facing the mounting groove 12, and the second magnetic strip and the first magnetic strip have opposite magnetic poles at positions opposite to each other, and their opposite magnetism can attract each other. By magnetically connecting the LCD screen 2 to the mounting frame 1 and providing magnetic strips along the edge thereof to form an annular magnetic connection, the connection stability can be improved, and the magnetic method makes it easy to disassemble and assemble the LCD screen 2 from the mounting frame 1, and to replace and repair the LCD screen 2.

[0036] As an example, a sliding hole is axially opened inside the positioning slider 3, and the sliding hole includes a pushing part 32, a sliding part 33 and a locking part 34 that are connected in sequence, and the pushing part 32 is close to the mounting frame 1, wherein the aperture of the sliding part 33 is smaller than the apertures of the pushing part 32 and the locking part 34; the positioning slider 3 is provided with a locking hole 35 connected with the locking part 34 on the side where the sliding groove is provided and away from the end of the mounting frame 1, and the locking hole 35 is inclined. By setting the pushing part 32, the sliding part 33 and the locking part 34 with different aperture sizes, the elastic locking component 4 is inserted into the positioning slider 3 to achieve sliding connection and facilitate elastic locking; by setting the locking hole 35 at the inner end to communicate with the locking part 34, a part of the elastic locking component 4 can pass through the locking hole 35 to be locked with the mounting device.

[0037] As an example, the elastic locking assembly 4 includes a pressing rod 41, a locking block 42 and a compression spring 43, the pressing rod 41 is sequentially inserted into the pushing portion 32, the sliding portion 33 and the locking portion 34; the compression spring 43 is located in the pushing portion 32 and is sleeved on the outside of the pressing rod 41, so that the pushing rod 41 can be elastically restored after being released; the cross-section of the locking block 42 is a right-angled trapezoid, and the inclined side of the locking block 42 is slidably set in the locking hole 35 through an elastic slider 38, and the angle between the inclined side of the locking block 42 and the pressing rod 41 is an acute angle, and the side of the locking block 42 close to the pressing rod 41 is provided with a receiving groove and abuts against the pressing rod 41. In the locked state, the locking block 42 partially passes through the locking hole 35 and is locked with the installation device. Through the above-mentioned structural design, when the pressing rod 41 is pushed to move toward the locking portion 34, the pressing rod 41 pushes the locking block 42 to move along the inclined surface of the locking hole 35, so that the locking block 42 retracts into the locking portion 34 and is unlocked from the installation device. At this time, the installation frame 1 and the LCD screen 2 can be pulled out and separated from the installation device; when installation is required, the pressing rod 41 is pushed in advance to keep the locking block 42 in a retracted state. When the installation frame 1 is slid into the installation device, the pressing rod 41 is released to release the locking block 42, so that it passes through the locking hole 35 and is locked with the installation device.

[0038] As an example, the inner wall of the locking hole 35 on one side away from the pressing rod 41 extends toward the locking portion 34 and is provided with a second sliding groove 36, so that the locking block 42 can slide into the locking portion 34, and a thin spring 37 is connected to one end of the second sliding groove 36 close to the locking portion 34, and the elastic slider 38 is slidably arranged in the second sliding groove 36 and connected to the thin spring 37. By elastically connecting the locking block 42 to the side wall of the locking hole 35, when the pressing rod 41 is released, the pressing rod 41 retracts and separates from the locking block 42, and the locking block 42 can automatically return to its position under the action of its elastic restoring force and pass through the locking hole 35. That is, when the pressing rod 41 is released, the locking block 42 always protrudes from the locking hole 35 and maintains locking with the installation device.

[0039] As an example, an L-shaped groove 421 is provided on one side of the locking block 42 close to the pressing rod 41, and a connecting block 44 is provided on one end of the pressing rod 41 away from the mounting frame 1, wherein the connecting block 44 abuts against the L-shaped groove 421, wherein the depth of the L-shaped groove 421 along the height direction of the locking block 42 is greater than the length of the connecting block 44, so that when the locking block 42 is tilted and moved into the locking portion 34 under the push of the pressing rod 41, there is no interference between the connecting block 44 and the locking block 42. In the locked state, the connecting block 44 abuts against a part of the L-shaped groove 421, and when the pressing rod 41 is pushed to move, the connecting block 44 pushes the locking block 42 to move along the inclined surface, at which time the contact area between the L-shaped groove 421 and the connecting block 44 gradually increases until the locking block 42 is completely moved into the locking portion 34, at which time the L-shaped groove 421 and the connecting block 44 are completely in contact. The above design can prevent the locking block 42 from interfering with the connecting block 44 during the tilting movement, thereby preventing the pushing of the pressing rod 41 from being affected.

[0040] As an example, the length of the first slide groove 31 of the positioning slide block 3 between the locking block 42 and the mounting frame 1 is greater than the length of the slide bar of the mounting device adapted to be connected thereto. By setting the length of the slide bar of the mounting device to be less than the length of the positioning slide block 3, after the mounting frame 1 is slid through the mounting device, the slide bar is located between the locking block 42 and the mounting frame 1, and the locking block 42 can abut against the rear end of the slide bar after passing through the locking hole 35, and the mounting frame 1 cannot be pulled out due to the obstruction of the slide bar, thereby locking the two.

[0041] Furthermore, a locking groove may be provided on the mounting device at a position corresponding to the locking block 42 and connected to the locking block 42 so that the locking block 42 is inserted into the locking groove and locked.

[0042] As an example, the pressing rod 41 is stepped, and the compression spring 43 is sleeved on the smaller diameter portion of the pressing rod 41. Through the above structural design, the compression spring 43 directly abuts against the pressing rod 41 and the inner wall of the pushing portion 32 to avoid separation.

[0043] As an example, a portion of the pressing rod 41 with a larger diameter is provided with a limiting ring 411, and the outer diameter of the limiting ring 411 is larger than the inner diameter of the pushing portion 32. By providing the limiting ring 411, the pressing ring can be limited to prevent the pressing ring from escaping from the positioning slider 3, thereby improving the stability of the structure.

[0044] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
