Referring to fig. 11 (a), a limit block 57 is fixedly disposed on the inner gear ring 51, and after the second bevel gear 52 is engaged with the third bevel gear 53 in a butt joint manner, the limit block 57 automatically moves upwards to form a blocking limit for the second bevel gear 52.
The stability of the connection of the second bevel gear 52 and the third bevel gear 53 is ensured, and the second bevel gear 52 does not elastically shrink when operating.
In an alternative manner of this embodiment, the limit clamping block 57 is provided with an inclined notch structure, and is located at a side close to the second bevel gear 52.
Providing protection for the upward movement of the limit block 57, avoiding the limit block 57 from being moved upward due to the incomplete engagement of the second bevel gear 52 and the third bevel gear 53.
The working principle of the monitoring camera applicable to the high-temperature environment provided by the embodiment is as follows:
in the initial state, as shown in fig. 1, two groups of mounting plates 21 are in a vertical state, the L-shaped fixing seat 1 is preferably and fixedly mounted on a vertical wall surface at a high point, the driving motor 3 is started, the driving motor 3 drives the threaded end 241 to rotate, the sliding rod 245 rotates, the telescopic end 242 rotates, the second bevel gear 52 rolls on the tooth surface of the inner gear ring 51, the mounting plates 21 start to rotate, the two groups of mounting plates 21 synchronously and reversely rotate along a vertical plane through two groups of meshed first bevel gears 23, and the threaded end 241 drives the camera body 4 connected with the threaded end 241 to move to the end part of the mounting plates 21 while the mounting plates 21 rotate;
when the mounting plate 21 is rotated to the horizontal state, as shown in (a) and (b) of fig. 11, the positioning slider 62 slides around the L-shaped fixing base 1 and is automatically aligned with the locking port 101 while the mounting plate 21 is rotated from the vertical state to the horizontal state, wherein the third bevel gear 53 is rotated to the horizontal state, and the second bevel gear 52 faces the third bevel gear 53;
After the mounting plate 21 rotates to a horizontal state, as shown in (c) and (d) in fig. 12, the positioning spring 61 pulls the positioning slide block 62 to advance, in the process that the positioning slide block 62 enters the locking opening 101, two groups of pushing plates 71 are preferably opened outwards, the pushing plates 71 drive the clamping plates 73 to be opened outwards, under the elastic contraction action of the contraction spring 65, the connecting disc 55 slides along the guiding inclined plane 732 to contract and is pressed on the second supporting surface 733, the telescopic shaft 54 contracts, and the inner gear ring 51 contracts and is automatically separated from the second bevel gear 52;
While the inner gear ring 51 is separated from the second bevel gear 52, the elastic member 244 pushes the sliding rod 245 to extend, the sliding rod 245 drives the second bevel gear 52 to advance through the telescopic end 242 and automatically engages with the tooth surface of the third bevel gear 53, and the second bevel gear 52 automatically engages with the third bevel gear 53 when rotating;
As shown in fig. 13 (e) and (f), in the process that the positioning slider 62 is completely clamped into the locking hole 101, the positioning slider 62 gradually breaks away from the support of the push plate 71, the push plate 71 rotates under the tension of the tightening spring 72, and the connecting disc 55 slides along the second supporting surface 733 and the guiding inclined plane 732 to extend toward the first supporting surface 731, so that the inner gear ring 51 drives the limiting fixture block 57 to lift again, and the limiting fixture block 57 provides a limit for the engaged second bevel gear 52, so as to ensure the stability of the engaged connection between the second bevel gear 52 and the third bevel gear 53.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
