Description

Plastic lens cone convenient to exhaust

Technical Field

The utility model relates to a lens cone field, in particular to plastic lens cone convenient to exhaust.

Background

Plastic lens barrels are commonly used to carry lenses in imaging lens modules and to provide optical spacing between any two lenses. The surface property of the plastic lens barrel is crucial to the suppression effect of stray light, and affects the imaging quality of the imaging lens. When the existing plastic lens cone is used for mounting the lens, gas is easy to generate and is difficult to discharge, so that the production quality of the lens is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem to the defect that exists among the above-mentioned prior art, provide a plastic lens cone convenient to exhaust to solve the problem of proposing among the above-mentioned background art.

In order to solve the technical problem, the utility model discloses the technical scheme who takes as follows: the utility model provides a plastic lens cone convenient to exhaust, includes like tip, side portion and the object end that sets gradually along the center pin, like the middle part of tip and seted up like the end trompil, like the bottom surface of tip and encircle like the end trompil and seted up a plurality of and be less than like the exhaust duct of tip bottom surface.

As a further elaboration of the above technical solution:

in the above technical solution, the exhaust grooves are arranged around the image end opening in a centrosymmetric manner.

In the above technical solution, the number of the exhaust grooves is 4.

In the above technical scheme, the exhaust groove is a square groove.

In the above-described aspect, the image edge portion, the object edge portion, and the side surface portion are integrally formed.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses the bottom surface of well image tip is encircleed the image end trompil and is seted up a plurality of and be less than the air discharge duct like the tip bottom surface, and the setting through the air discharge duct increases switching on of air, makes the inside gas of camera lens discharge smoothly.

fig. 3 is a cross-sectional view of the present invention.

In the figure: 1. an image end portion; 11. opening a hole at the image end; 12. an exhaust groove; 2. a side surface portion; 3. and (4) an end part.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiments described by referring to the drawings are exemplary and intended to be used for explaining the present application and are not to be construed as limiting the present application. In the description of the present application, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and thus should not be considered limiting. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral connections; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate. In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly above and obliquely above the second feature, or simply meaning that the first feature is at a lesser level than the second feature.

As shown in fig. 1-3, a plastic lens barrel facilitating air exhaust comprises an image end portion 1, a side portion 2, and an object end portion 3 sequentially arranged along a central axis, wherein an image end opening 11 is formed in the middle of the image end portion 1, and a plurality of air exhaust grooves 12 lower than the bottom surface of the image end portion 1 are formed in the bottom surface of the image end portion 1 around the image end opening 11.

In this embodiment, the exhaust grooves 12 are arranged in a central symmetry manner around the image end opening 11, so as to reduce the warpage and deformation in the injection molding process of the plastic lens barrel. The number of the exhaust grooves 12 is 4, so that air can be smoothly exhausted. The exhaust grooves 12 are provided as square grooves. Of course, the specific number, distribution and shape of the exhaust grooves 12 can be set according to the actual situation, and is not limited in this embodiment.

In this embodiment, the image end 1, the side portion 2 and the object end 3 are integrally formed, so that the overall structure is more stable and compact, and the plastic lens barrel is convenient to be injection molded.

The utility model discloses well like the bottom surface of tip 1 and set up a plurality of around like end trompil 11 and be less than like exhaust duct 12 of 1 bottom surface of tip, set up through exhaust duct 12 and increase switching on of air, make the inside gas of camera lens discharge smoothly.

The above is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
