DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1:

[0030] Reference Figure 1-6 , the mounting support includes an upper mounting plate 201, a mounting rod 401, and also includes: a mounting block 207, which is fixedly connected to the upper mounting plate 201, and the mounting block 207 is hollow; a gear 402, which is fixedly connected to the mounting rod 401; a slot 1 2091, which is arranged on the mounting block 207; a slot 2092, which is arranged on the mounting block 207, and the slot 1 2091 and the slot 2 2092 are used together to insert the gear 402 into the mounting block 207; a tooth groove 208, which is arranged in the mounting block 207, and the tooth groove 208 is consistent with the shape of the gear 402. The intrinsically safe display screen for coal mines includes a mounting support and a display screen body 1, and the display screen body 1 is installed at the bottom of the upper mounting plate 201.

[0031] When the device is in use, the end of the mounting rod 401 not provided with the gear 402 is fixed to the shaft support of the mine by welding or other methods. Figure 6 As shown, the gear 402 can be inserted into the mounting block 207 through slot 1 2091 and slot 2 2092. After adjusting to a suitable angle, it can be loosened. Under the weight of the upper mounting plate 201 itself, the gear 402 will be stuck in the tooth groove 208. At this time, the angle adjustment is completed. Subsequently, the display screen body 1 is installed at the bottom of the upper mounting plate 201, and the display screen can be started to complete the installation.

[0032] When the angle needs to be adjusted later, the upper mounting plate 201 can be lifted upward to separate the tooth groove 208 from the gear 402, and then the upper mounting plate 201 can be rotated. After reaching the appropriate angle, the upper mounting plate 201 can be loosened. At this time, under the action of its own weight, the mounting block 207 moves downward, and the gear 402 will cooperate with the tooth groove 208 again to complete the angle adjustment. At this time, there may be a mismatch, and the upper mounting plate 201 needs to be slightly rotated until the gear 402 cooperates with the tooth groove 208.

[0033] In the present application, the display screen body 1 is a mining explosion-proof display of the brand Shantai Intelligent and model JBY127, which has the capabilities of earthquake resistance, explosion resistance and moisture resistance.

[0034] Embodiment 2:

[0035] Reference Figure 1-6 , the mounting support and the intrinsically safe display screen for coal mines are basically the same as those in Example 1, and further, it also includes a lower mounting plate 202, the lower mounting plate 202 is arranged below the upper mounting plate 201, the upper mounting plate 201 and the lower mounting plate 202 are both slidably connected with a clamping plate 204, the upper mounting plate 201 and the lower mounting plate 202 are both provided with a slide groove 203, the clamping plate 204 is slidably connected in the slide groove 203, the slide groove 203 is internally threadedly connected with a rotating bolt 205, the clamping plate 204 is threadedly connected to the rotating bolt 205, and both ends of the upper mounting plate 201 and the lower mounting plate 202 are provided with a placement groove 206, and the placement groove 206 An extension plate 301 is slidably connected inside, and a locking bolt 302 is threadedly connected on the upper mounting plate 201. The locking bolt 302 is used to fix the extension plate 301 in the placement groove 206. An empty hole is provided on the extension plate 301, and a screw rod 303 is slidably connected in the empty hole. A nut 304 is threadedly connected on the screw rod 303, and the nut 304 is used to connect the extension plate 301 of the lower mounting plate 202 with the extension plate 301 of the upper mounting plate 201. The top and bottom of the display screen body 1 are respectively mounted on the upper mounting plate 201 and the lower mounting plate 202, and the clamping plate 204 is used to fix the display screen body 1 on the upper mounting plate 201 and the lower mounting plate 202.

[0036] When installing the display screen body 1, the position of the lower mounting plate 202 can be adjusted by adjusting the height of the nut 304, and the display screen body 2 is placed on the lower mounting plate 202, and then the position of the nut 304 is adjusted again to move the lower mounting plate 202 upward until the top and bottom of the display screen body 1 can respectively abut against the upper mounting plate 201 and the lower mounting plate 202, and then the rotating bolt 205 can be rotated. By rotating the rotating bolt 205, the clamping plate 204 moves in the slide groove 203 until it abuts against the display screen body 1, thereby completing the fixation of the display screen.

[0037] If the display screen body 1 is relatively large, the extension plate 301 can be extended from the placement slot 206. When the extension plate 301 reaches a suitable length, the locking bolt 302 can be tightened to fix the extension plate 301, which is convenient for installing some relatively large display screens.

[0038] The utility model can clamp the gear 402 in the tooth groove 208 through the cooperation between the gear 402 and the tooth groove 208 under the weight of the support and the display screen. When used in a mine shaft, the angle can be quickly adjusted for easy use.

[0039] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
