Since the LCD unit adopts a front pop-up method, the installation space between the LCD unit and the bracket body is still insufficient, resulting in inconvenience in installation and maintenance, and increasing the difficulty of installation and maintenance. Summary of the invention

[0003] The present invention provides an LCD screen splicing module that is easy to install and maintain, which overcomes the shortcomings of the background technology. One of the technical solutions adopted by the present invention to solve its technical problems is:

[0004] An LCD screen splicing module that is easy to install and maintain, comprising a bracket, a first slide, a second slide, a folding frame, a hanging frame, a locking mechanism and at least one LCD screen, wherein:

[0005] The bracket is provided with at least one slide rail, and the slide rail has a first slide section and a second slide section;

[0006] The first sliding bracket is slidably matched with the first sliding section of the slide rail and is hingedly connected to the hanging bracket;

[0007] The second slide bracket is slidably matched with the second slide section of the slide rail, and the two ends of the folding bracket are respectively hingedly connected to the second slide bracket and the hanging bracket, and the folding bracket moves between a folding position and an open position;

[0008] The LCD screen is mounted on a bracket;

[0009] The locking mechanism comprises a first locking part mounted on the bracket and a second locking part mounted on the rack, the first locking part and the second locking part being separably locked together;

[0010] When the first locking part is separated from the second locking part, the rotating hanger drives the first slide to slide along the first sliding section, the second slide slides along the second sliding section, and the folding frame moves from the folded position to the open position to form a triangular area between the hanger, the folding frame and the bracket.

[0011] In a preferred embodiment, when the first locking portion is locked with the second locking portion, the folding frame is parallel to the bracket or the hanging frame.

[0012] In a preferred embodiment: a tension spring is connected between the first slide and the bracket, and when the first locking portion is separated from the second locking portion and the hanger is rotated, the tension spring can pull the first slide to slide along the first sliding section.

[0013] In a preferred embodiment, the sliding stroke of the first slide is smaller than the sliding stroke of the second slide.

[0014] In a preferred embodiment: the first sliding section is provided with a first limiting portion and a second limiting portion at the front and rear ends respectively, and the first sliding rack slides between the first limiting portion and the second limiting portion.

[0015] In a preferred embodiment: the second sliding section is provided with a third limiting portion and a fourth limiting portion at the front and rear ends thereof, respectively, and the second sliding bracket slides between the third limiting portion and the fourth limiting portion.

[0042] Please refer to Figures 1 to 3 A preferred embodiment of an LCD screen splicing module that is easy to install and maintain is disclosed. The LCD screen splicing module that is easy to install and maintain includes a bracket 10, a first slide 20, a second slide 30, a folding frame 40, a hanging frame 50, a locking mechanism and at least one LCD screen 60.

[0043] The bracket 10 corresponds to two LCD screens 60, forming a splicing module 1; Figure 1 As shown, the splicing screen is spliced ​​using three splicing modules 1. Two adjacent brackets 10 are placed together and locked to the wall by screws. Fig.12 As shown, one bracket 10 corresponds to three LCD screens 60 and are arranged at intervals along the height direction of the bracket 10 to form a splicing module 1. When actually splicing, the modules can be stacked according to the required size. The interval between two adjacent LCD screens 60 mentioned here is only a small gap, which is not in contact and is difficult to be detected by the naked eye. Fig.13 As shown, one bracket 10 corresponds to four LCD screens 60 and are arranged at intervals along the height direction of the bracket 10 to form a splicing module 1. Alternatively, one bracket 10 may also correspond to one LCD screen 60 to serve as a splicing module 1. In the actual splicing process, splicing modules 1 of different sizes may be spliced ​​as needed to form a splicing screen in a square, trapezoidal, or other shape.

[0044] The bracket 10 is provided with at least one slide rail, and the slide rail has a first slide section 11 and a second slide section 12. Figure 5 As shown, the first sliding section 11 is located at the rear end of the slide rail, and the second sliding section 12 is located at the front end of the slide rail. In addition, two slide rails are provided and arranged at intervals up and down.

[0045] The first slide 20 is slidably matched with the first slide section 11 of the slide rail and is hingedly connected to the hanger 50. The second slide 30 is slidably matched with the second slide section 12 of the slide rail, and the two ends of the folding frame 40 are respectively hingedly connected to the second slide 30 and the hanger 50, and the folding frame 40 moves between a folded position and an open position.

[0046] like Figure 7As shown, the first slide 20 includes a first slide bar 21 and two first sliders 22 respectively fixed at the upper and lower ends of the first slide bar 21, the two first sliders 22 are respectively slidably matched with the two first sliding sections 11, and the first slide bar 21 is hingedly connected to the hanger 50 by hinges. The second slide 30 includes a second slide bar 31 and two second sliders 32 respectively fixed at the upper and lower ends of the second slide bar 31, the two second sliders 32 are respectively slidably matched with the two second sliding sections 12. The folding frame 40 includes a vertical rod 41 and two cross rods 42 respectively fixed at the upper and lower ends of the vertical rod 41, the second slide bar 31 is hingedly connected to the vertical rod 41 of the folding frame 40 by two hinges, and the two cross rods 42 are hingedly connected to the hanger 50 by hinges. Moreover, the height of the vertical rod 41 is the same as that of the second slide bar 31.

[0047] In this embodiment, the sliding stroke of the first slide 20 is smaller than the sliding stroke of the second slide 30, that is, the length of the first sliding section 11 is smaller than the length of the second sliding section 12. Figure 8 As shown, the length of the second sliding section 12 is close to half the length of the sliding rail.

[0048] In this embodiment, the first sliding section 11 is provided with a first limiting portion 111 and a second limiting portion 112 at the front and rear ends, respectively, and the first sliding block 21 slides between the first limiting portion 111 and the second limiting portion 112. Figure 7 As shown, the first limiting portion 111 is a limiting block fixed in the slide rail, and the second limiting portion 112 is a side edge of the bracket 10 .

[0049] In this embodiment, the front and rear ends of the second sliding section 12 are respectively provided with a third limiting portion 121 and a fourth limiting portion 122, and the second sliding block 32 slides between the third limiting portion 121 and the fourth limiting portion 122. Figure 5 As shown, the third limiting portion 121 is a limiting plate, and when the second slider 32 moves to below the limiting plate, the limiting plate and the second slider 32 are tightly matched to limit the continued sliding of the second slider 32. The fourth limiting portion 122 has the same structure as the first limiting portion 111, and both are limiting blocks. When the second slider 32 slides backward and abuts against the limiting block, it stops sliding.

[0050] The locking mechanism includes a first locking portion 71 installed on the bracket 10 and a second locking portion 72 installed on the hanging bracket 50, and the first locking portion 71 and the second locking portion 72 are locked and matched in a separable manner; when the first locking portion 71 and the second locking portion 72 are separated, the rotating hanging bracket 50 drives the first slide 20 to slide along the first sliding section 11, the second slide 30 to slide along the second sliding section 12, and the folding frame 40 moves from the folding position to the opening position so that the hanging bracket 50, the folding frame 40 and the bracket 10 form a triangular area. In this embodiment, when the first locking portion 71 and the second locking portion 72 are locked and matched, the folding frame 40 is parallel to the bracket 10 or the hanging bracket 50. In this embodiment, the locking mechanism adopts a press-type spring lock structure, which is a prior art.

[0051] In this embodiment, a tension spring 80 is connected between the first slide 20 and the bracket 10. When the first locking portion 71 and the second locking portion 72 are separated and the bracket 50 is rotated, the tension spring 80 can pull the first slide 20 to slide along the first sliding section 11. Figure 7 As shown, two ends of the tension spring 80 are fixed to the first sliding rod 21 and the bracket 10 respectively.

[0052] In this embodiment, the first locking portion 71 is fixed to the limiting plate and faces the hanging bracket 50 .

[0053] The LCD screen 60 is mounted on the bracket 50 .

[0054] In this embodiment, at least one hanging rod 61 is provided on the back of the LCD screen 60, and a U-shaped hanging piece 62 is fixedly connected to the hanging rod 61. The U-shaped hanging piece 62 is hung on the hanging rack 50, and a locking piece is provided to lock the U-shaped hanging piece 62 and the hanging rack 50 together. Fig.10 As shown, the locking piece is a screw, and two hanging rods 61 arranged at intervals on the left and right are arranged on the back of each LCD screen 60, and two U-shaped hanging pieces 62 arranged at intervals on the outside of each hanging rod 61 are fixedly connected. The hanging rack 50 includes a square frame 51, and two horizontal support rods 52 arranged at intervals on the left and right sides of the frame 51 are arranged on the top of the frame 51, and the two upper U-shaped hanging pieces 62 of the LCD screen 60 located at the top are hung on the top of the frame 51, and the two lower U-shaped hanging pieces 62 of the LCD screen 60 located at the top are hung on the two horizontal support rods 52 located at the top; similarly, the two upper U-shaped hanging pieces 62 of the LCD screen 60 located at the bottom are hung on the two horizontal support rods 52 located at the bottom, and the two lower U-shaped hanging pieces 62 of the LCD screen 60 located at the bottom are hung on the bottom of the frame 51.

[0055] like Figure 1 and Figure 2As shown, the LCD screen 60 of each splicing module 1 is in a closed state, the first locking portion 71 and the second locking portion 72 are in a locked state, the first slider 22 is placed on the second limiting portion 112, the second slider 32 and the third limiting portion 121 are tightly matched, and the folding frame 40 is in a folded state;

[0056] The second locking portion 72 is pressed inward to separate the second locking portion 72 from the first locking portion 71. At this time, the hanging bracket 50 or the LCD screen 60 is rotated outward, and the first slider 22 slides along the first sliding section 11 under the action of the tension spring 80. The folding frame 40 is slowly opened under the drive of the hanging bracket 50. Figure 3 and Figure 4 When the first slider 22 slides to the second limit portion 112, it stops sliding, as shown Figure 5 and Figure 6 The bracket 50 is rotated outwardly to drive the folding frame 40 to continue to open and drive the second slider 32 to slide along the second sliding section 12 until the second slider 32 stops sliding when it abuts against the fourth limit portion 122. At this time, the opening angle of the bracket 50 or the LCD screen 60 is the maximum. Figure 7 and Figure 8 shown.

[0057] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention.
