Abstract
The utility model discloses a locking anti-loosening structure for an optical lens. The locking anti-loosening structure for the optical lens comprises a fixed cylinder and an adjustable ring which is sleeved on the fixed cylinder. The locking anti-loosening structure for the optical lens is characterized in that: an elastic pad is embedded in the adjustable ring; a limiting screw is provided outside the adjustable ring; one end of the liming screw successively passes through the adjustable ring and the elastic pad and movably abuts against the side part of the fixed cylinder. The locking anti-loosening structure for the optical lens has the following advantages: simple structure, high use convenience and high popularization value.
Description
Technical field
The utility model relates to the optical equipment technical field, especially relates to a kind of locking anti-loose structure of optical lens.
Background technology
Optical lens is requisite parts in the Vision Builder for Automated Inspection, directly affects the quality of image quality, affects realization and the effect of algorithm.Optical lens divides from structure the fixed aperture tight shot, manual iris tight shot, automatic diaphragm fixed focus lens, manually zoom lens, automatic zoom camera lens etc.Wherein, manually the focal length of zoom lens is variable, and a Focussing ring is arranged, and can adjust within the specific limits the focal length of camera lens, and its variable ratio is generally 2-3 doubly, and focal length is generally 3.6-8mm.In the practical application, can by the zoom ring of manual adjustments camera lens, can select easily the visual angle.But the zoom ring is through after repeatedly regulate using, all can produce loosening, thereby cause the problems such as focusing is inaccurate.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple in structure, the locking anti-loose structure of the optical lens of stable performance.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of locking anti-loose structure of optical lens, it comprises stationary magazine creel and regulating ring, regulating ring is set on the stationary magazine creel, it is characterized in that, described regulating ring is embedded with the bullet pad, arranged outside limited location screw, an end of stop screw passes regulating ring and bullet pad successively, and movable top is pressed on the sidepiece of stationary magazine creel.
As further specifying of such scheme, described stop screw anterior stepped, the bullet pad is fixed in this end difference.
The inboard of described regulating ring is provided with the arc caulking groove corresponding with the bullet pad, and the sidepiece of this caulking groove arranges opening, and stop screw passes behind this opening and the press fit of stationary magazine creel top.
The lower edge of described bullet pad is provided with flanging, and this flanging is provided with through hole, by securing member is arranged on the through hole bullet pad and regulating ring is connected and fixed.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the bullet pad corresponding with stop screw is set in regulating ring, and the reacting force by the end difference top of stop screw presses the bullet pad to produce makes spacing spiral shell Nail and female tooth close-fitting, even also can not produce loosening under vibrational state.

Description of reference numerals: 1, stationary magazine creel 2, regulating ring 3, bullet pad 4, stop screw 5, end difference 6, arc caulking groove 7, opening 8, flanging 9, through hole.
Embodiment
Such as Fig. 1-shown in Figure 4, the locking anti-loose structure of a kind of optical lens of the utility model, it comprises stationary magazine creel 1 and regulating ring 2, regulating ring 2 is set on the stationary magazine creel 1, regulating ring 2 is embedded with bullet pad 3, arranged outside limited location screw 4, an end of stop screw 4 passes regulating ring 2 and bullet pad 3 successively, and movable top is pressed on the sidepiece of stationary magazine creel.Wherein, stop screw anterior stepped, the bullet pad is fixed in this end difference 5.The inboard of regulating ring 2 is provided with the arc caulking groove 6 corresponding with the bullet pad, and the sidepiece of this caulking groove arranges opening 7, and stop screw passes behind this opening and the press fit of stationary magazine creel top.The lower edge of bullet pad is provided with flanging 8, and this flanging is provided with through hole 9, by securing member is arranged on the through hole bullet pad and regulating ring is connected and fixed.
In the use procedure, when tightening stop screw, the bullet pad is pressed on the end difference of stop screw top, and the stressed generation shell fragment of bullet pad is out of shape, and can be formed at the elastic force of the direction of arrow as shown in Figure 3, and it is stressed to use screw to produce in this direction, prevents from becoming flexible under vibration state.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
