[0002] A billboard is a large outdoor advertising display medium, usually set up in places with large traffic and wide visibility, such as on both sides of roads, commercial districts, on highways, or on the exterior walls of buildings. Its purpose is to attract public attention and disseminate commercial information, brand image, product promotion, public service announcements, etc.

[0003] Existing billboards are usually installed by pasting or bolting, and lack auxiliary limiting supports. After long-term use, the billboards are easily affected by external forces or loosened due to corrosion of the bolts, which can easily cause the billboards to fall off. This not only increases the workload of subsequent maintenance, but also easily creates safety hazards, which is not conducive to the long-term and stable use of the billboards. Summary of the invention

[0008] Preferably, the movable sleeve on the fixing bolt is provided with a rubber gasket, and the front and rear end surfaces of the rubber gasket are respectively fitted to the rear end surface of the mounting frame and the front end surface of the butterfly nut.

[0009] Preferably, the outer diameter of the fixing bolt is smaller than the vertical length of the strip hole.

[0010] Preferably, a rubber sleeve is pasted on the side surface of the clamping block, and the thickness of the clamping block is greater than the thickness of the billboard.

[0011] Preferably, the adjustment assembly includes a bidirectional screw rod rotatably installed in the sliding frame and a handwheel arranged on the outside of the mounting frame. The bidirectional screw rod is threadedly connected to the rear end of the movable frame, and the bidirectional screw rod moves through the inner side of the sliding frame and is connected to the handwheel.

[0012] Preferably, two positioning screws are fixedly mounted on the rear end surface of the billboard, and a positioning nut is threadedly mounted on each positioning screw.

[0013] Beneficial effects of the utility model:

[0020] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0021] like Figure 1As shown, the utility model provides an anti-drop billboard, comprising a mounting frame 1, a billboard 2 closely attached to the front end face of the mounting frame 1, and a positioning screw 3 horizontally fixed to the rear end face of the billboard 2. The positioning screw 3 horizontally moves through the front and rear end faces of the mounting frame 1, and a positioning nut 4 is threadedly installed on the positioning screw 3. The positioning nut 4 is closely attached to the rear end face of the mounting frame 1. The billboard 2 is fixed by the positioning nut 4 and the positioning screw 3, thereby improving the stability of the billboard 2 during use.

[0022] In this embodiment, two positioning screws 3 are fixedly installed on the rear end face of the billboard 2, and a positioning nut 4 is threadedly installed on each positioning screw 3. The two positioning screws 3 are respectively matched with two positioning nuts 4 to improve the installation stability of the billboard 2 to reduce the possibility of the billboard 2 falling off.

[0023] like Figures 1 to 4 As shown, in this embodiment, two sliding frames 5 are movably installed on the front end surface of the mounting frame 1, and the sliding frames 5 can move in the up-down direction along the front end of the mounting frame 1. The two sliding frames 5 are respectively attached to the upper and lower ends of the rear end surface of the billboard 2, and two movable frames 6 are slidably installed in each sliding frame 5. The movable frames 6 can move horizontally in the left and right directions along the inner side of the sliding frame 5. Two conical clamping blocks 7 are installed on the front end surface of the movable frames 6. The two conical clamping blocks 7 are used to clamp the corners of the billboard 2. The billboard 2 is clamped by the clamping blocks 7, thereby improving the stability of the billboard 2 and further preventing the billboard 2 from falling off.

[0024] An adjustment component is provided outside the movable frame 6 for adjusting the horizontal position of the movable frame 6;

[0025] The side surface of the clamping block 7 is pasted with a rubber sleeve 13, and the thickness of the clamping block 7 is greater than the thickness of the billboard 2, which is conducive to the clamping block 7 applying a stable clamping force to the billboard 2;

[0026] In this embodiment, a strip hole 9 is provided on the mounting frame 1, and a fixing bolt 10 is movably passed through the strip hole 9. The fixing bolt 10 is connected to the sliding frame 5 after passing through the inner side of the strip hole 9, and a butterfly nut 11 is threadedly installed on the fixing bolt 10. The butterfly nut 11 is located at the rear of the mounting frame 1. The fixing bolt 10 is driven by the sliding frame 5 to move vertically in the strip hole 9 to adjust the position of the sliding frame 5 to provide support for the billboard 2;

[0027] Among them, a rubber gasket 12 is provided on the movable sleeve of the fixing bolt 10, and the front and rear end surfaces of the rubber gasket 12 are respectively attached to the rear end surface of the mounting frame 1 and the front end surface of the butterfly nut 11, which helps to prevent the butterfly nut 11 from loosening by itself under vibration or external force, and improves the stability of the butterfly nut 11 connecting the fixing bolt 10;

[0028] The outer diameter of the fixing bolt 10 is smaller than the vertical length of the strip hole 9, which is conducive to the vertical movement of the fixing bolt 10 in the strip hole 9 to adjust the position of the sliding frame 5;

[0029] In this embodiment, the adjustment assembly includes a bidirectional screw rod 8 rotatably mounted in the sliding frame 5 and a hand wheel 14 arranged on the outside of the mounting frame 1. The bidirectional screw rod 8 is threadedly connected to the rear end of the movable frame 6, and the bidirectional screw rod 8 horizontally moves through the inner side of the sliding frame 5 and is connected to the hand wheel 14.

[0030] Specifically, when in use, the sliding frame 5 is moved so that the front end surface of the sliding frame 5 is in contact with the rear end surface of the billboard 2. When the two clamping blocks 7 on the front end surface of the sliding frame 5 are adjusted to face the corners of the billboard 2, the sliding frame 5 is stopped. At this time, the butterfly nut 11 is rotated to drive the rubber gasket 12 to be in contact with the rear end surface of the mounting frame 1, so that the sliding frame 5 is fastened to the mounting frame 1 through the butterfly nut 11 and the fixing bolt 10.

[0031] Then, the bidirectional screw rod 8 is driven to rotate by rotating the hand wheel 14, and the bidirectional screw rod 8 drives the two movable frames 6 to move symmetrically inward in the sliding frame 5. The two movable frames 6 respectively drive the two groups of clamping blocks 7 and rubber sleeves 13 to move inward and fit the side surface of the billboard 2. Rotating the two hand wheels 14 respectively can drive the four groups of rubber sleeves 13 on the two movable frames 6 to fit the four corners of the billboard 2, so that the four groups of clamping blocks 7 clamp and fix the four corners of the billboard 2. At this time, the billboard 2 is clamped and fixed in the up, down, left and right directions. Since the clamping block 7 is conical and its side surface is an inclined surface, when the inclined side surface of the clamping block 7 applies a clamping force in the up, down, left and right directions to the side surface of the billboard 2, the inclined side surface of the clamping block 7 cooperates with the front end of the mounting frame 1 and the sliding frame 5 to apply a clamping force in the front and back directions to the billboard 2, so as to provide all-round clamping and fixation for the billboard 2, improve the stability of the billboard 2 during use, and reduce the possibility of the billboard 2 falling off.

[0032] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
