Abstract
The utility model relates to a focusing structure of a waterproof enclosed camera, which comprises a limiting gear ring, a magnet attracting iron block, telescopic bars and the like. The gear ring is used as a limiting structure and is combined with the magnet attracting iron block. A gear structure which is fit to the gear ring is arranged at the lower part of the iron block. The iron block is connected to a camera lens through a spring telescopic bar. The iron block is attracted away and limited by an external magnet. The zooming and the focusing of the camera lens can be realized by sliding the external magnet. When an image on the camera lens is clear, the external magnet is moved away and the iron block is in close fit with the gear ring under the effect of the pulling force of a spring to lock the camera lens and prevent the camera lens from being deviated. By adopting the focusing structure, the defect that the waterproof performance is reduced because holes are additionally arranged on the shell of the camera can be avoided. The focusing structure is particularly suitable for focusing the camera lens of an underwater monitoring camera.
Description
Technical field
The utility model belongs to technical field of security and protection, relates to a kind of integrated sealed type video camera, and especially the magnetic-type focusing structure of with infrared waterproof camera is relevant.
Background technology
Integrated sealed formula video camera, as infrared waterproof integrated video camera, tight shot fixed focal length in the use of reality, the actual environment for use of client is various, cause the shooting of video camera can't reach state the most clearly, and carrying out the focusing again of camera lens, the machine of tearing open can relate to the repair and maintenance problem, in order to satisfy this request for utilization, developed the structure of outer focusing on the market, but this structure belongs to the external mechanical screw rod and relates to, there is the relatively poor problem of water resistance, for the shooting functional adaptation that makes outdoor hermetic type rainy, moist, the demand that supervises in real time under the water environment, we have proposed a kind of magnetic-type focusing structure, realize the focusing to the manual zoom lens of video camera on the basis of the equipment of assurance water resistance.
Summary of the invention
The purpose of this utility model is to solve the aforementioned problems in the prior, and a kind of focusing structure of water-proof sealing video camera is provided, and mainly is beneficial to the manually zoom lens adjusting of image field angle at the scene in the closed video camera.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
A kind of focusing structure of water-proof sealing video camera, described focusing structure comprises:
Two elastic telescopic screw rods: the change that connects zoom lens is doubly enclosed and focusing circle, flexible screw rod
Being divided into is nested inside and outside two joints does along the bar direction and to prolong and shrink, and following joint is connected on the camera lens, and last joint links to each other with the suction magnet piece, is provided with the flexible gravitation of spring as two poles in saving up and down;
Inhale magnet piece: be arcuate structure, it is concavo-convex that inner arc is designed to gear, and middle and last pole links to each other.
The position limits gear ring: its two toothrows race cooperates with the suction magnet piece, and hollow out is for the slip of expansion link between two rows;
Described focusing structure is installed on the inside of video camera.
The following joint of described two elastic telescopic screw rods adopts hickey to be connected on the camera lens.
Adopt technique scheme,,, make equipment play waterproof effect to greatest extent so equipment need not to carry out unnecessary perforate because it adopts the physical action of magnetic force.Utilize this focusing structure, the shortcoming that can avoid the other perforate of camera housing to cause water proofing property to reduce is particularly suitable for the camera lens focusing of rig camera under water.
Description of drawings:
Fig. 1 is a planar structure synoptic diagram of the present utility model;
Fig. 2 is a perspective view of the present utility model;
Fig. 3 is an action synoptic diagram of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Consult shown in Fig. 1-3, the focusing structure of a kind of water-proof sealing video camera of embodiment of the present utility model, two elastic telescopic screw rods 1: the change that connects zoom lens is doubly enclosed and focusing circle, and flexible screw rod is divided into being nested inside and outside two joints to do along the bar direction and prolongs and shrink, and 11 times joint adopts spiral shells
The line interface is connected on the camera lens, on save 12 with inhale magnet piece and link to each other, be provided with the flexible gravitation of spring 4 in saving up and down as two poles; Inhale magnet piece: be arcuate structure, it is concavo-convex that inner arc is designed to gear, and middle and last pole links to each other.The position limits gear ring 3: its two toothrows race cooperates with the suction magnet piece, and hollow out is for the slip of expansion link between two rows; Described focusing structure is installed on the inside of video camera.
Described focusing structure iron block under the spring tension effect of expansion link is attached on the gear ring, because the position-limiting action of gear, make the focal length of camera lens be fixed, when the magnetic force of extraneous magnet 5 is done the time spent greater than the pulling force of spring, iron block is sucked from the tooth punching wheel rim, the extraneous magnet that slides gets final product indirect mobile iron block, drives expansion link by iron block and makes camera lens regulate.Iron block lost magnetic force after magnet was taken away, and was promptly retracted by the pulling force of spring and was fixed on and finishes the fixing of focal length on the gear ring.
The design of focusing structure of the present utility model: 1) adopt magnet, guaranteed the water proofing property 2 of equipment) adopt gear ring as spacing, be difficult for sliding 3 as the focusing instrument). adopt the telescopic spring rod member, simple in structure.
The utility model is mainly used in the manual zoom lens focusing of hermetic type video camera, adopts reasonably design to guarantee the water proofing property of video camera.
The above only is preferred embodiment of the present utility model, so all according to the described structure of the utility model patent claim, the equivalence that feature and principle are done changes or modifies, and is included in the utility model patent claim.
