The focusing of machine camera lens or zoom, and ensure that lateral pull will not be produced to camera lens during lens location is locked.
Realize that the technical scheme of the utility model purpose is as described below：
A kind of unstressed locking device for being applied to lens focus or zoom, the camera lens locking device is arranged on video camera
On lens assembly, the lens assembly includes camera lens and the light shield being arranged on the camera lens, it is characterised in that：The locking dress
Put including switching part, tight lock part, intermediate conversion portion, described switching part one end, which is fixedly connected on, needs the part of locking on camera lens,
Including focusing and/or zoom portion, the other end is provided with a chute, flexible side when the track length direction is with lens focus or zoom
To vertical direction it is consistent, the intermediate conversion portion is arranged in the chute, and can be moved along the track length direction, centre turn
Portion is changed to be locked with light shield.
Described intermediate conversion portion structure is the sliding block being adapted to the chute, and the sliding block is fastened in the chute, and should
Sliding block and the chute are that gap coordinates, and the sliding block is axial to be respectively equipped with spacing at the two ends relative to chute, and the sliding block is vertically
Provided with screwed hole, the sliding block is locked by described tight lock part through the hole slot on light shield with the light shield.
The unstressed locking device for being applied to lens focus or zoom that the utility model is provided, is turned using a centre
Changing device, to reach following effect：1. lens focus or zoom can be carried out easily, and ensure lens focus or become defocused
Position can be locked；2. camera lens locking device is during locking, telescopic direction that will not be when with lens focus or zoom
Pulling force is produced on vertical direction, skew will not be produced by making the picture of shooting.

Embodiment
To further appreciate that feature of the present utility model and its advantage, spy is with embodiment to of the present utility model specific
Embodiment is described in detail as follows：
The unstressed locking device for being applied to lens focus or zoom that the present embodiment is provided, with a switching part 4, one lock
Intermediate conversion portion of tight portion 5 and one, Fig. 3 is the lens group of the dome type monitor video camera using the present embodiment camera lens locking device
The partial cutaway schematic of part, the lens assembly includes camera lens 1, and light shield 3 is arranged on the base of camera lens 1, on the light shield 3
Hole slot 31 with a Long Circle, the hole slot 31 of the Long Circle be using light shield 3 around the circular arc direction of the central shaft of camera lens 1 as
Its length direction is arranged on light shield 3, and the effect of switching part 4 is similar to the connecting rod of a switching, and the one end of switching part 4 uses machine
Fixed screw 7 processed is fixed on the focusing ring 11 in the part for needing to adjust and lock on camera lens 1, such as the present embodiment, switching part 4
The end may also be arranged on the zoom portion of camera lens 1, the other end of switching part 4 is provided with a chute 41, the length side of chute 41
To focused on camera lens 1 or during zoom telescopic direction vertical direction it is consistent, the intermediate conversion portion is arranged in the chute 41, and can
Moved along the length direction of chute 41 in the chute 41, i.e., intermediate conversion portion can be focused on or flexible side during zoom along camera lens 1
To vertical direction movement, intermediate conversion portion is locked with light shield 3 by tight lock part 5, as shown in Figure 4.
In the present embodiment, intermediate conversion portion structure uses the sliding block 6 being adapted to above-mentioned chute 41, and the sliding block 6 is fastened on this
In chute 41, and the sliding block 6 coordinates with the chute 41 for gap, sliding block 6 is moved vertically in the length direction of chute 41, should
The two ends of the axial direction of sliding block 6 are respectively equipped with spacing 61, after sliding block 6 is caught in the chute 41 on switching part 4, it is ensured that the sliding block 6 is in cunning
Slidably it can will not fall off simultaneously in groove 41, such as Fig. 5, Fig. 6.
The sliding block 6 is provided with screwed hole 62 vertically, and the screwed hole can be, an or blind hole axially elongated along sliding block 6.
Hole slot 31 is set tight lock part 5 is locked on light shield on light shield 3, while empty as focusing or the operation of zoom
Between.The sliding block 6 is locked by tight lock part 5 through the hole slot 31 on light shield 3 with the light shield 3, tight lock part 5 tighten when
Time can play locking action, and lens focusing or the handle of zoom, such as Fig. 7 can be used as when unscrewing.Tight lock part 5 can be
One screw or a handle for carrying screw function.
Tight lock part 5 is simply locked sliding block 6 and light shield 3 when locking, due to sliding block 6 and switching part 4 it
Between can be in horizontal direction（Lock the direction of stress）On slidably, therefore locking during only sliding block 6 can be produced
Raw horizontal pulling force, but lateral pull will not be produced to the switching part 4 being fixed on camera lens 1, camera lens 1 would not also be produced
Lateral pull, therefore influence will not be produced on the imaging of camera lens, as shown in Figure 8.
The utility model needs to focus on by switching part 4 and camera lens 1 or the part of zoom portion is fixedly connected, by one
Between fiddling with for converter section 6 carry out the regulation of lens focus or zoom, be eliminated locking device and produced during locking
Raw lateral pull, i.e., telescopic direction that will not be when with lens focus or zoom produces pulling force on vertical direction, so as to protect
Card is adjusting the focusing of camera lens or is becoming defocused, and when locking lens location, the picture of lens shooting will not produce skew.
