As shown in fig. 7, the side of the spare part 24 facing away from the sliding opening 12 is provided with a separation column 242, and the side wall of the lens 11 on the same side is also provided with a separation column 242, so that when the lens provided with the separation column 242 moves upwards, the separation column 242 can pass through the sliding opening 12.

So that a gap is formed between two adjacent spare parts 24, and the gap between two adjacent spare parts 24, that is, the length of the partition column 242, is greater than the thickness of the cross bar 53 extending along the length of the partition column 242.

Through setting up the column 242 for when the spare part 24 of tip is in mount pad 111 inside, mount pad 111 is at the in-process that moves down, and horizontal pole 53 locks spare part 24, and horizontal pole 53 has the part to be located between two adjacent spare parts 24 this moment, and horizontal pole 53 can be smooth moves to between two spare parts 24, realizes the effect that furthest carries out the location to spare part 24.

In an embodiment of the present invention, a control element may be further provided, wherein the first driving mechanism 3, the second driving mechanism 4 and the charged workpiece may be connected to the control element, and the lens 11 is controlled to be replaced by the control element, so that difficulty in replacing lenses in the camera is low, and replacement efficiency is high.

The application principle of a security protection camera that is applicable to special environment in this embodiment does:

when the user needs to replace the lens 113 which is seriously worn and located inside the body 1, the first driving mechanism 3 needs to be opened at first, the lens 11 which is located inside the body 1 is driven to move upwards through the first driving mechanism 3, and when the lens 11 moves upwards along the sliding opening 12, the shielding piece 14 is pulled out to shield the opening of the body 1, so that the influence of external dust on the electronic element inside the body 1 is avoided.

Then, the lens 11 moves upward, and on the way to the case 2, the cross bar 53 is pressed by the vertical bar 54, so that the cross bar 53 moves toward the third spring 442, and finally the cross bar 53 is kept in a state of not shielding the mounting member 112, and the mounting member 112 can be detached from the mounting seat 111, fall on the recovery plate 26, and slide along the inner bottom surface of the case 2, so that the mounting member 112 and the lens 113 are horizontally positioned on the inner bottom surface of the case 2.

Finally, the second driving mechanism 4 is started, the second driving mechanism 4 drives the sliding base 21 to move towards the installation base 111, after the spare part 24 on the sliding base 21 moves into the installation base 111, the standby part 24 is kept in a tight state, then the installation base 111 is moved downwards through the first driving mechanism 3, at this time, in the downward moving process of the installation base 111, the cross rod 53 is gradually separated from the vertical rod 54 and moves to one side of the installation base 111, the spare part 24 is locked in the installation base 111, the sliding base 21 is driven by the second driving mechanism 4 to move to the initial position, and at this time, the shielding part 14 also returns to the initial position. Separation of the severely worn lens 113 is achieved and replacement of the spare part 24 into the mounting seat 111.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and all technical solutions that belong to the idea of the present invention belong to the scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
