DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0018] Examples of the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to be illustrative of the present application and are not to be construed as limiting the present application.

[0019] Referring to Figure 1-4 A liquid crystal display maintenance tool comprises a stable floor 1, an inclined support frame 2, an adjusting rotating block, and four mounting rods mounted on the adjusting rotating block. The bottom end of the inclined support frame 2 is fixed at a position close to one side of the stable floor 1, and the top end is above the center of the stable floor 1. The top end of the inclined support frame 2 is provided with a mounting disc 21. The adjusting rotating block comprises a U-shaped joint 3 and a mounting square plate 4. The U-shaped joint 3 is fixed to the lower surface of the mounting square plate 4. The axis position of the mounting disc 21 is provided with a bolt hole. The two side plates of the U-shaped joint 3 are provided with locking bolt holes matched with the bolt hole. After the U-shaped joint 3 is sleeved on the mounting disc 21, the locking bolt 31 is passed through the locking bolt hole and the bolt hole, and a nut is sleeved at the other end. The upper surface of the mounting square plate 4 is provided with a square notch at each corner position. The mounting rod comprises a rotating rod 5 and an L-shaped clamping head 6. One end of the rotating rod 5 is a semicircular plate, and the other end is provided with a N-shaped connector. The L-shaped clamping head 6 is provided with a movable clamping plate 62. The L-shaped clamping head 6 is provided with a spiral clamping bolt 61, and the clamping bolt 61 is rotatably installed on the back of the clamping plate 62. The lower half of the L-shaped clamping head 6 is provided with an insertion rod 63. The insertion rod 63 is inserted into the N-shaped connector and locked by an angle adjusting bolt 64. The semicircular plate end of the four rotating rods 5 is mounted in the four square notches by bolts.

[0020] For small liquid crystal displays (small televisions, computer displays), when maintaining, the display is buckled on the maintenance table and laid horizontally. When maintaining, the head needs to be bent down, which will cause discomfort of the cervical vertebrae for a long time. The liquid crystal display is buckled on the four L-shaped clamping heads 6 (the rotating angle of the rotating rod 5 is adjusted according to the size of the display in advance), and after buckling, the L-shaped clamping head 6 is locked by the angle adjusting bolt 64 to prevent rotation along the N-shaped connector at the other end of the rotating rod. The clamping bolt 61 is rotated to push out the clamping plate 62 to press the side of the liquid crystal display to fix the display. Then, according to the needs, the angle between the U-shaped joint 3 and the mounting disc 21 is rotated, and the U-shaped joint 3 and the mounting disc 21 are locked by the locking bolt 31 to prevent rotation, so as to realize the angle of the liquid crystal display required for maintenance, which makes the maintenance more suitable for the maintainer, the bending degree is small, and the maintenance is more convenient.

[0021] The two side surfaces of the mounting disc 21 are both corrugated frosted surfaces 211. The corrugated frosted surfaces 211 can make the U-shaped joint 3 clamping the mounting disc 21 more firm, and will not rotate after being locked.

[0022] The bottom wall surface of the square notch is frosted. The rotating rod is only attached to the bottom wall of the square notch and cannot be easily rotated.

[0023] The rotating angle of the rotating rod 5 is 0-90°. Four rotating rods can realize a large range of adjustment to fix various types of display screens.

[0024] When the mounting square plate 4 is horizontally placed, the horizontal plane of the platform position on the L-shaped clamping head 6 is higher than the horizontal plane of the upper surface of the mounting square plate 4. The liquid crystal display is buckled on the four L-shaped clamping heads 6, and the liquid crystal display cannot be against the mounting square plate 4, and the display screen is in a suspended state. The display screen is not damaged.

[0025] The included angle between the inclined support frame 2 and the stable floor 1 is 45-60°. It is more stable and firm.

[0026] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
