Description

Technical Field

[0001] The utility model relates to the technical field of mining cameras, in particular to a novel mining explosion-proof camera. Background Art

[0002] Since the environment in coal mines is very harsh, gas leaks and explosions of flammable and explosive objects often occur. In order to transmit information from underground coal mines to the surface in a timely manner, intrinsically safe flameproof cameras are generally used for the transmitted image signals. The main function of this camera is to collect video images of the working surface and send them to the host or monitor via Ethernet. It is suitable for dangerous places in coal mines where there are methane and coal dust explosions.

[0003] The current installation method for explosion-proof cameras requires pre-drilling holes in the wall and then mounting the camera on the wall with bolts. However, when replacing a camera of a different model or size, the mounting holes on the new camera often cannot be aligned with the original mounting holes on the wall, and then re-drilling and installation are required, which wastes a lot of time.

[0004] Therefore, a new type of explosion-proof camera for mining is proposed. Summary of the Invention

[0005] The purpose of the present utility model is to provide a novel explosion-proof camera for mining to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel explosion-proof camera for mining, comprising a fixing frame, support frames symmetrically mounted on both sides of the fixing frame, and a camera body mounted on the support frames;

[0007] The four corners of the fixing frame are rotatably connected to a connecting plate, the connecting plate is slidably connected to a slider, and the slider is installed with a first fixing bolt.

[0008] Preferably, a rotating drum is installed on one side of the connecting plate.

[0009] Preferably, a third fixing bolt is provided inside the rotating drum, and the third fixing bolt is threadedly connected to the fixing frame.

[0010] Preferably, a sliding groove is provided on the connecting plate.

[0011] Preferably: the slider includes a first slider and a second slider;

[0012] The first sliding block and the second sliding block are respectively located on both sides of the connecting plate and are both slidably connected to the interior of the sliding groove.

[0013] Preferably, the first slider and the second slider are fixedly connected via a second fixing bolt.

[0014] Preferably, a connecting cylinder is installed on the first sliding block, and the first fixing bolt is located inside the connecting cylinder.

[0015] Compared with the prior art, the beneficial effect of the present invention is that the first fixing bolt can be driven to move by the rotatable connecting plate and the sliding slider, thereby adjusting the position of the first fixing bolt so that the first fixing bolt is aligned with the original mounting hole on the wall, thereby completing the overall installation work, eliminating the process of re-drilling and improving the installation efficiency throughout the day.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a new type of explosion-proof camera for mining, comprising a fixing frame 1, support frames 2 are symmetrically installed on both sides of the fixing frame 1, and a camera body 3 is installed on the support frame 2;

[0023] The four corners of the fixing frame 1 are rotatably connected to a connecting plate 4 , a sliding block 5 is slidably connected to the connecting plate 4 , and a first fixing bolt 6 is installed on the sliding block 5 .

[0024] like Figure 4 As shown: a rotating drum 41 is installed on one side of the connecting plate 4, and a third fixing bolt 9 is provided inside the rotating drum 41, and the third fixing bolt 9 is threadedly connected to the fixing frame 1; through the above arrangement, the position of the rotating drum 41 and the connecting plate 4 can be restricted by tightening the third fixing bolt 9, and the third fixing bolt 9 can also be loosened at the same time, so that the connecting plate 4 and the rotating drum 41 can be rotated more conveniently.

[0025] like Figure 4 As shown: a slide groove 8 is opened on the connecting plate 4; through the above setting, the slide groove 8 can enable the slider 5 to drive the second fixing bolt 7 to move, and then the second fixing bolt 7 can be more conveniently adapted to the original installation hole.

[0026] like Figure 4 As shown: the slider 5 includes a first slider 51 and a second slider 52; the first slider 51 and the second slider 52 are respectively located on both sides of the connecting plate 4, and are both slidably connected to the inside of the slide groove 8; through the above arrangement, the cross-sections of the first slider 51 and the second slider 52 are both T-shaped, and the protruding protrusions are both located inside the slide groove 8 and aligned with each other, and then their positions are restricted by the second fixing bolt 7, so that the first slider 51 and the second slider 52 are combined with each other and can slide inside the slide groove 8.

[0027] like Figure 4 As shown: the first slider 51 and the second slider 52 are fixedly connected by the second fixing bolt 7; through the above arrangement, tightening the second fixing bolt 7 can fix the first slider 51 and the second slider 52 together, thereby fixing the position of the slider 5 so that it cannot move to ensure the position of the first fixing bolt 6.
