Abstract

The utility model relates to an image pick-up device, which keeps a shading cover of an image pick-up head contacting with an internal surface of a spherical cover through action of an elastic mechanism to eliminate clearances. The image pick-up device comprises an image pick-up lens, a spherical cover and a support, wherein the spherical cover contacts with the image pick-up lens, and the support is in pivot arrangement with the image pick-up lens. The image pick-up lens consists of an annular step, an elastic element, a shading cover, through grooves, through holes and a fixed element, wherein the annular step is coaxially convexly arranged with a casing of the image pick-up lens via the middle portion of the casing of the lens, the elastic element is sleeved on a casing of the annular step arranged at the front end of the lens, the through grooves are symmetrically arranged on the shading cover, the through holes are symmetrically arranged at corresponding portions of the lens, the shading cover is connected with the casing of the lens via the fixed element, and the shading cover can move in the stroke of the through groove relative to the casing at the front end of the lens. Pluralities of infrared illuminating lamps are arranged in a chamber body formed by the image pick-up lens and the spherical cover contacting with the same.

Description

Camera head

Technical field

The utility model relates to a kind of camera head.

Background technology

Present dome-type infrared eye on the market, the camera that contacts with the inside surface of transparent hemisphere sphere cover is a rigid structure, make and easily have the gap between camera lens and the sphere cover inner surface, the infrared light that the video camera infrared lamp sends enters camera lens through the reflection of transparent hemisphere face shield, make camera views produce bad phenomenon such as hot spot, reduced the image quality of video camera.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of effect by elastic mechanism that the shading cover of camera is touched the sphere cover inner surface all the time to eliminate the camera head in gap.

The purpose of this utility model can reach by following measure:

This camera head, comprise pick-up lens, with the support that pick-up lens touches the sphere cover, is pivoted with pick-up lens, its special character is: described pick-up lens is positioned at flexible member sheathed on the housing of camera lens front end, shading cover, groove that the shading cover symmetry is offered, perforation that camera lens corresponding position symmetry is offered, shading cover is connected with lens housing and shading cover can be formed relative to the element that sets firmly that the camera lens front end shell moves at its groove stroke by the housing middle part of camera lens and the coaxial circular step that is convexly equipped with of this housing, this circular step; Be provided with some infrared illumination lamps in the formed cavity of sphere cover that pick-up lens touches with it.

The purpose of this utility model can also reach by following measure:

Described shading cover is convexly equipped with the groove that lid, this lid identical with sphere cover inner surface shape position symmetry adjacent with the ring-type projection offer by ring-type cylinder, one end and forms.

Described flexible member is a spring.

Described flexible member is a foam.

The utility model has following advantage compared to existing technology:

1, has big elastic telescopic stroke, and the shading cover that mating surface and the hood-shaped shape of transparent hemisphere coincide can with the complete driving fit of transparent hemisphere cover, stopped infrared light that the video camera infrared lamp sends and entered camera lens, also eliminated the harmful effect that this kind reason produces camera views through the reflection of transparent hemisphere face shield.

2, owing to the shading cover with camera lens one camera lens has big elastic telescopic stroke, make the assembly precision of video camera require to reduce greatly, be convenient to the carrying out of producing in batches.
