Abstract

The utility model provides a prevent glue excessive glue component contains the space ring, the one end of space ring has a step face, and two recesses have been seted up by nearly far away to the surface of this step face, are first recess and second recess respectively, first recess is used for loading glue, the second recess is used for loading the glue that overflows behind the light filter extrusion glue, wherein, the width and the degree of depth of second recess all are less than first recess. The structure can prevent the optical filter from loosening in transportation and use, prevent the influence on the use performance of the lens and prevent the appearance of the lens. The structure is mainly suitable for the lens with the optical filter which has the requirement on the light wavelength.

Description

Component for preventing glue from overflowing

Technical Field

The utility model relates to a can prevent that the light filter is not hard up in transportation, use, prevent to influence the performance of camera lens, prevent the camera lens outward appearance.

Background

Fig. 2 is a structural diagram of a conventional mechanism (before filter assembly): a conventional optical filter dispensing mechanism, as shown in fig. 2, includes a lens barrel 101, a spacer 201, a lens P01, and an optical filter G01. In order to prevent the optical filter from falling off during transportation and use due to insufficient bonding strength, the multi-point glue 301 is dispensed in the dispensing groove 401 of the spacer ring. Fig. 3 is a structural diagram of a conventional mechanism (after filter assembly): comprises a lens barrel 101, a space ring 201, a groove 401, a lens P01 and a filter G01. After the glue 301 is filled, the filter is loaded, as shown in fig. three. The glue will overflow and attach to the lens surface and the filter surface, which will cause the following problems:

1. when the optical filter is assembled, the optical filter can be inclined, and the heights of the two ends of the optical filter are different;

2. when the glue overflows to the surface of the lens, the effective optical path of the lens is blocked, so that the effective light of the lens cannot be completely transmitted, and the imaging effect of the lens is influenced; meanwhile, the glue overflowing on the surface of the lens can also cause the lens to generate stray light, thereby influencing the imaging effect of the lens;

3. the glue overflows to the surface of the optical filter, so that the effective light with the lens cannot be completely transmitted, and the imaging effect of the lens is influenced; meanwhile, the glue overflowing on the surface of the lens can also cause the lens to generate stray light, thereby influencing the imaging effect of the lens;

4. the appearance of the lens is also not attractive after the glue overflows.

At present, the domestic lens industry is developed towards the direction of miniaturization, multifunction and strong environment adaptability, and under the form of very fierce domestic competition, the requirements on different light-passing of the lens are increasingly strict, the fixing modes of various lenses are different, and for producers, how to enable consumers to use the lenses more conveniently becomes the problem that people need to overcome. When a consumer uses the lens to take a picture, the duration of the picture is long because the optical filter in the lens is loose, the optical filter is assembled unevenly, the lens causes stray light, the optical filter causes stray light, the effective light of the lens cannot be completely transmitted, and the appearance of the lens is not attractive, so that the comprehensive performance of the lens is not strong, and the trouble is brought to manufacturers and consumers. The structural device is designed to solve the problem.

SUMMERY OF THE UTILITY MODEL

The utility model provides a prevent glue and overflow gluey component, its characterized in that contains the space ring, the one end of space ring has a step face, and two recesses have been seted up by nearly far away on the surface of this step face, be first recess and second recess respectively (the other end also can be set up for same symmetry), first recess is used for filling glue, the second recess is used for filling the glue that overflows after the light filter extrudees glue, wherein, the width and the degree of depth of second recess all are less than first recess.

Preferably, the width of the first groove is 0.65mm and the depth is 0.4mm, and the width of the second groove is 0.4mm and the depth is 0.3 mm.

Preferably, and lens barrel, lens and optical filter.

The component can prevent the optical filter from loosening in transportation and use, prevent the influence on the service performance of the lens and prevent the appearance of the lens. The component is mainly suitable for the lens with the optical filter which has the requirement on the light wavelength.

Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.

The following modified (before filter assembly) structure of fig. 4: in order to avoid the problems in the prior art, the space ring is modified, as shown in fig. 1, 2 and 5, and includes a lens barrel 101, a space ring 201, a first groove 4011, a second groove 4012, a lens P01 and a filter G01, wherein the depth and width of the second groove are smaller than those of the first groove. In the same way, the optical filter can not fall off during transportation and use due to insufficient bonding strength, so that the optical filter can be glued in the glue dispensing groove of the space ring in multiple points. After the glue is dispensed, the filter is loaded as shown in FIG. 5. The glue filling the first recess 4011 will overflow into the second recess 4012, which will avoid the following problems:

3. the glue overflows to the surface of the optical filter, so that the effective light with the lens cannot be completely transmitted, and the imaging effect of the lens is influenced; meanwhile, the glue overflowing on the surface of the lens can also cause the lens to generate stray light, so that

Thereby affecting the imaging effect of the lens;

4. the appearance of the lens is not attractive after the glue overflows;

the device is convenient and practical, and effectively solves the problems that the optical filter is not flexible, the assembly of the optical filter is not flat, the lens causes stray light, the optical filter causes stray light, the effective light of the lens cannot completely pass through, and the appearance of the lens is not attractive, so that the imaging effect of the lens is influenced, and the consumer can shoot images with good quality.

It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
