The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] Example one:

[0026] Please refer to Figures 1-5 The technical solutions of the present application are provided as follows:

[0027] Specifically refers to a kind of advertising light box anti-impact mechanism, including advertising light box, and advertising light box is by support 1, display screen 2, camera 8 is formed, camera 8 can monitor outside advertising light box, when the spacing between external article or person and display screen 2 is close, retractable rod 302 and motor 701 are instructed, camera 8 can monitor the spacing between article and display screen 2, personnel and display screen 2, and can instruct retractable rod 302 and motor 701, the technical solution is prior art, not too much elaboration here, support 1 is provided with the roller shutter baffle 303 for protecting display screen 2 by protection piece 3, support 1 is movably installed with the shutter one 4 and shutter two 5 that are arranged in dislocation and protect display screen 2, positioning structure 6 is installed on support 1 to position shutter one 4 and shutter two 5.

[0028] The working principle of the advertising light box provided by the utility model is as follows: the roller shutter baffle 303 is unfolded to intercept and protect the display screen 2, and the deflection of the shutter one 4 and the shutter two 5 can intercept and protect the display screen 2.

[0029] Embodiment two

[0030] On the basis of specific embodiment one, the difference of the embodiment is that:

[0031] As shown in Figure 2 Protection piece 3 includes frame 301 fixedly installed on support 1, and support column is installed in frame 301, and roller shutter baffle 303 is arranged on support column, retractable rod 302 electrically connected with camera 8 is fixedly installed in frame 301, and the output end of retractable rod 302 is fixedly connected with traction steel rope 304 connected with roller shutter baffle 303.

[0032] The output end of retractable rod 302 is retracted to drive traction steel rope 304 to move, so that traction steel rope 304 unfolds roller shutter baffle 303, and roller shutter baffle 303 intercepts and protects display screen 2, and roller shutter baffle 303 unfolds around support column, so that two roller shutter baffles 303 can intercept and protect display screen 2 from both sides, to avoid that display screen 2 is excessively impacted in the running process.

[0033] Embodiment three

[0034] On the basis of specific embodiment two, the difference of the embodiment is that:

[0035] As shown in Figure 5As shown, the positioning structure 6 includes a vertical plate fixedly installed on the bracket 1, and a movable rod 601 is slidably sleeved on the vertical plate. A positioning rod 602 extending into the baffle 4 and the baffle 5 is fixedly installed on the movable rod 601. A movable block 603 is fixedly installed on the movable rod 601, and a spring 604 cooperating with the movable rod 601 is welded between the movable block 603 and the vertical plate. A pressing structure 7 for pressing the movable block 603 is installed on the bracket 1. The vertical plate guides the movable rod 601 so that the movable rod 601 can smoothly pull the positioning rod 602 and the movable block 603 when moving. The spring 604 resets the movable block 603. When the movable block 603 is in an unloaded state, the spring 604 drives the movable rod 601 and the movable block 603 back to the initial position.

[0036] After the moving block 603 is disconnected from the pressing block 704, the moving rod 601, under the action of the spring 604, drives the positioning rod 602 to disconnect from the first baffle 4 and the second baffle 5. Under the action of gravity, the first baffle 4 and the second baffle 5 deflect onto the partition on the bracket 1, so that the first baffle 4 and the second baffle 5 form an X-shape to protect the display screen 2. To further explain, the staggered setting of the first baffle 4 and the second baffle 5 can avoid the collision of the first baffle 4 and the second baffle 5 when rotating, and the partition can intercept the first baffle 4 and the second baffle 5. The X-shape of the first baffle 4 and the second baffle 5 can protect the display screen 2 again.

[0037] Example 4:

[0038] Based on specific embodiment two, the difference in this embodiment is as follows:

[0039] like Figure 3 As shown, the movable rod 601 is set horizontally, and the ends of the baffle 1 4 and baffle 2 5 away from the display screen 2 are connected to the bracket 1 by a pin. The bracket 1 is equipped with a partition for intercepting the baffle 1 4 and baffle 2 5. The spring 604 is sleeved on the movable rod 601, and the positioning rod 602 and the movable rod 601 extend to one side outside the upright plate.

[0040] Example 5:

[0041] Based on specific embodiment two, the difference in this embodiment is as follows:

[0042] like Figure 5 As shown, the extrusion structure 7 includes a motor 701 fixedly mounted on the bracket 1, and a bidirectional lead screw 702 is fixedly connected to the output end of the motor 701. After the motor 701 is powered on, it drives the bidirectional lead screw 702 to rotate on the bracket 1. This technical solution is existing technology and will not be elaborated on here. Two matching nuts 703 are slidably sleeved on the bidirectional lead screw 702, and an extrusion block 704 that moves against the moving block 603 is fixedly mounted on the nut 703.

[0043] Embodiment six:

[0044] On the basis of the specific embodiment two, the different point of this embodiment is:

[0045] As shown in Figure 5 The bidirectional screw rod 702 is horizontally arranged at the middle end position of the support 1, the moving block 603 is provided with a slope, and the extrusion block 704 is a ladder-shaped structure matched with the moving block 603.

[0046] The motor 701 drives the bidirectional screw rod 702 to rotate, and the bidirectional screw rod 702 drives the two nuts 703 to move towards or reversely when rotating, and when the two nuts 703 move close to each other, the extrusion block 704 is disconnected with the two moving blocks 603, and the partition plate can lock the positions of the baffle one 4 and the baffle two 5.

[0047] After the slope on the moving block 603 and the extrusion block 704 are extruded, the positions of the baffle one 4 and the baffle two 5 can be locked, and the normal operation of the display screen 2 is guaranteed.

[0048] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this. Any simple change, equivalent replacement or modification made on the basis of the present application to solve the same technical problem and achieve the same technical effect is also covered by the protection scope of the present application.
