Please referring to shown in Figure 6, on the whole existing monitoring camera is provided with the hollow main shell holder 70 of open front on one day, one is covered on the protecgulum 71 of main shell holder 70 front ends, an and camera that is installed on protecgulum 71 and main shell holder 70 inside, main shell holder 70 inner near front end places are provided with a support 72, show the circuit board 73 of LED in support 72 the place ahead fixed interval one cloth, described phtographic lens device promptly is located at support 72 and circuit board 73 centers, this camera comprises a lens group 80 again, be sheathed on a focal length adjustment ring 81 and a visual angle adjustment ring 82 outside the lens group 80, ring-like perisporium in focal length adjustment ring 81 and visual angle adjustment ring 82 is respectively equipped with a radially outstanding focal length adjustment post 83 again, post 84 is adjusted at the visual angle, stir this focal length and adjust post 83 and visual angle and adjust post 84 and can adjust the photography focal length respectively, and be that wide-angle or full length shot are photographed.

In order to prevent the camera damage of making moist, therefore, clipping one sealing ring 74 between protecgulum 71 and main shell holder 70, whole monitoring camera has promptly been assembled and has been finished before dispatching from the factory.Only, during installation, perhaps in the use, need look supervising environment and adjust focal length and visual angle, adjust current situation necessity and take protecgulum 71 apart, dialling changes that focal length is adjusted post 83 or post 84 is adjusted at the visual angle again, and to be adjusted finishing covers protecgulum again, not only dismantles and assemble loaded down with trivial details.And during adjustment, whole camera is to expose to the open air in the middle of air, and moisture will cause the damage of making moist of camera lens and electronic package.

Event, existing monitoring photographing device cause having difficult the adjustment because structural design is bad, and the shortcoming of assembly moisture-sensitive damage, and necessity of further improvement is arranged really.

Summary of the invention

In order to improve above-mentioned shortcoming, fundamental purpose of the present utility model is to provide that a kind of anti-rain is convenient adjusts camera lens visual angle and focal length, and the space monitoring camera that can effectively use.

Based on above-mentioned purpose, major technique means of the present utility model are to provide a kind of monitoring camera of convenient fine setting camera lens, comprise that the main shell holder, of a hollow is covered on the protecgulum of main shell holder front end, and is fixed in the camera that the interior support, of main shell holder is installed on carriage center, this camera further comprises a lens group, a focal length adjustment ring, a visual angle adjustment ring, it is characterized in that:

The bottom of this main shell holder and protecgulum is respectively equipped with an outstanding prominent seat of hollow form down in this section that fit, and two prominent seats communicate with main shell holder, protecgulum inside respectively, and the prominent seat front end of protecgulum is provided with two axial adjustment holes parallel with lens group;

This frame bottom is provided with the prominent board that extends under one day and be positioned at prominent seat;

An if adjusting gear, comprise one first sector gear, one second sector gear, one first adjusts gear, one second adjusts a gear and a capping, wherein, this capping is the prominent seat front end that is covered on protecgulum, and capping is provided with and is placed through two protruded stigmas of adjusting in the hole, this is first years old, second sector gear is individually fixed in focal length adjustment ring, the ring-like outer peripheral edges of visual angle adjustment ring, this first adjustment gear and second is adjusted gear and is hubbed on the prominent board, and respectively with first, the engagement of second sector gear, this is first years old, second adjusts gear front end center is respectively equipped with first an axially outstanding adjustment axle, one second adjusts axle, this is first years old, the second adjustment axle is to be placed through two of protecgulum respectively to adjust holes, first, second adjusts shaft end is provided with slot, and in first, second adjusts axle goes up a sheathed sealing ring respectively, and the sealing ring is to be packed in to adjust the hole internal perisporium.

Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is:

1. the convenient photography focal length of adjusting, visual angle: under the utility model normality, be to utilize the capping sealing to be covered on two to adjust the hole, and first, second adjusts axle also utilizes a sealing ring packing to be closed in the internal perisporium of adjusting the hole, therefore, at the beginning of monitoring camera is installed, when needing to adjust photography focal length or visual angle after perhaps installing, as long as open capping, stretch into a wherein adjustment hole with the bottle opener instrument, plug-in card is adjusted axle or second in first and is adjusted in the slot of axle, can be so that the first adjustment gear or second be adjusted the gear rotation, and then drive the rotation of first sector gear or second sector gear, rotate to adjust focal length adjustment ring or visual angle adjustment ring, so structural design of the present utility model can directly be adjusted the focal length of lens group under the situation of not dismantling protecgulum, the visual angle.

2. blocks moisture enters in the main shell holder in advance: because the first adjustment axle and second is adjusted axle and adjusted between the hole with the sealing ring packing, therefore, when opening the capping adjustment, be unlikely to make airborne moisture to enter, so not only convenient the adjustment, also can avoid inner moist and cause assembly impaired.

3. can effectively utilize the space: because focal length adjustment ring of the present utility model outside, and one section sector gear is only established in adjustment ring outside, visual angle, but not domain gear, therefore, space beyond the sector gear scope of activities can be used again, install for other assembly, its structural design has the advantages that to save the space.
