Specific embodiment

Below in conjunction with drawings and embodiments, the invention will be further described.

As shown in Figs. 1-2, the present invention provides a kind of barrel 10, including with accommodating space 11 barrel 1, be set to institute The light hole 2 of one end of the close object side of barrel 1 is stated, is embedded inside the barrel 1 and empties chamber 3, through-hole 4,5 and of hole piston part Black material 6.

The barrel 1 includes main barrel 12 and is prolonged from one end of the close object side of the main barrel 12 to optical axis direction bending The accommodating space 11 is collectively formed in the secondary barrel 13 stretched, the two.

The light hole 2 is arranged through the secondary barrel 13, and the light hole 2 is set on the secondary barrel 13.

The chamber 3 of emptying includes that first to be interconnected empties chamber 31 and second and empty chamber 32.Described first empties chamber 31 Be arranged in parallel with the medial surface of the main barrel 12, described second empty chamber 32 with described secondary the medial surface of barrel 13 is parallel sets It sets.

The through-hole 4 can be opened in any position of the barrel 1 for the chamber 3 of emptying to be in communication with the outside.Tool Body, in present embodiment, the through-hole 4 can be opened in the medial surface of the barrel 1.More preferably, the through-hole 4 is located at described One end far from the secondary barrel 11 of main barrel 12.

The hole piston part 5 is filled at the through-hole 4, for sealing the through-hole 4.The hole piston part 5 is not limited to this Form, or glue or other sealing elements, as long as can be by 4 fill plug seal of through-hole.

The black material 6 is emptied in chamber 3 described in being filled in, including is filled in described first and is emptied chamber 31 and described second Empty chamber 32.In order to keep the light-blocking performance of the barrel 1 good, described first empties chamber 31 and described second empties institute in chamber 32 Stating black material 6 need to fill completely.

In present embodiment, the black material 6 is black liquor.

More preferably, the main barrel 12, the secondary barrel 13, described empty chamber 3 and the through-hole 4 is integrated and is molded into Type.

In present embodiment, the black material 6 is black liquor, convenient for filling, such as by micro needle head through described logical The black material 6 is injected to described empty in hole 4 in chamber 3.

The black material 6 has interception, so that barrel 1 has better shaded effect, reduces stray light.

More preferably, the black material 6 is graphene liquid.Certainly, the black material 6 is not limited to this, can also be with Black ink or blacking etc., it is only necessary to by it is described empty chamber 3 fill and be able to achieve light blocking effect.

Barrel 10 of the invention when in use, has good shaded effect, is able to achieve by its own, user Just, it enhances product performance.

It is the flow chart of the processing method of barrel of the present invention incorporated by reference to shown in Fig. 3.The present invention also provides a kind of barrels Processing method, be illustrated by taking above-mentioned barrel of the invention as an example, this method comprises the following steps:

Step S1, barrel is provided, including the barrel 1 with accommodating space 11 and set on the close object side of the barrel 1 One end light hole 2.

Step S2, it opens up and empties chamber, opened up in the inside of the barrel 1 and empty chamber 3, make the chamber 3 of emptying close to described The inside of barrel 1 and the medial surface setting for being parallel to the barrel 1.

Step S3, aperture material feeding opens up through-hole 4 in the inside of the barrel 1 and the chamber 3 of emptying is made to pass through the through-hole 4 are in communication with the outside；Injection black material in chamber 3 is emptied to described by the through-hole 4.

In this step, the black material 6 is graphene liquid.Certainly, the black material is also not limited to this, can also To be the black liquors such as black ink or blacking, as long as being able to achieve shading performance.

In this step, specifically, the black material 6, which is injected by micro needle head by the through-hole 4, described empties chamber 3 It is interior.

Step S4, sealing of hole, by 4 encapsulation process of through-hole.

It, can be by the way that hole piston part 5 be filled at the sealing that the through-hole 4 realizes the through-hole 4 in this step.Certainly, described Hole piston part 5 is not limited to this form, or glue or other sealing elements, as long as can be by 4 fill plug seal of through-hole.

Fig. 4 is please referred to, is the structural schematic diagram of lens module of the present invention.Present invention simultaneously provides a kind of lens modules 100, including barrel and the eyeglass 20 being contained in the barrel, the barrel is the described of aforementioned present invention offer Barrel 10.

Compared to the prior art, barrel of the invention opened up on the inside of its barrel it is described empty chamber, by being drawn described Black material is injected in cavity and is sealed, so that gear veiling glare effect can be better achieved in the barrel itself；When described When barrel applies to the lens module provided by the invention, the lens module can stop to shine by the barrel itself The veiling glare formed on the barrel is penetrated, and without increasing additional components, so that assembly technology is simplified, good in optical property； The processing method of barrel of the invention is simple, the barrel its good in optical property processed.

The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills Art field, is included within the scope of the present invention.
