Abstract

A digital camera lens cone comprises at least two casings, wherein each case is inwardly provided with a top portion and a plurality of spaces which are corresponding to each other and forming a ring, the top portion of each casing forms the top portion of the digital camera lens cone, having a funnel shaped hole, each housing has a plurality of card holes and card bamboo shoots which cooperate with each other and form the housings into the lens of the digital camera of which the outer surface has outer screws which engage with the inner screws of the holding assemblies to lock and fix the lens into the holding assemblies. The lens have low assemble difficulties, thereby efficiently avoiding angle deviation when packing, improving assemble efficiency, and reducing assembling working hours.

Description

The digital camera lens barrel

[technical field]

The utility model is about a kind of digital camera lens barrel, especially about a kind of digital camera lens barrel that is used for portable electron device.

[background technology]

Continuous development along with science and technology, portable electron device such as mobile phone, use increasingly extensive, also day by day trend towards simultaneously light and handy, attractive in appearance and multifunction, wherein camera function is the additional function of mobile phone new development in recent years, and mobile phone has two kinds of external hanging type and in-building types with combination between digital camera and mobile phone.Existing in-building type mobile phone sees also Fig. 1 with the digital camera lens barrel, this digital camera lens barrel 10 comprises stack shell 11 and loam cake 14, this stack shell 11 is that a hollow circuit cylinder is to hold a plurality of rubber blankets 13 and a plurality of lens 12, rubber blanket 13 in the form of a ring, these a plurality of lens 12 and a plurality of rubber blanket 13 are filled in the cavity (indicating) of the stack shell 11 that is loaded on this digital camera at interval during assembling, rubber blanket 13 is between per two lens 12, to locate the spacing of these lens 12.Loam cake 14 is installed at last with a plurality of lens 12 in the fixed lens barrel 10.

This structure of this digital camera lens barrel 10 makes can only be put into a plurality of lens 12 and a plurality of rubber blanket 13 plugs in its cavity from the opening of a direction when assembling, and package program is complicated, and the assembling yield is on the low side.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of assembling convenient, the higher digital camera lens barrel of assembling yield.

The utility model digital camera lens barrel comprises two housings at least, this at least two housings be combined into the tubular host body successively.

Compare prior art, the assembling of the utility model digital camera lens barrel can be prior to installing lens on a certain housing, again in conjunction with other housing, make that the assembling difficulty is little, avoid filling in the angular deviation that causes when adorning and cause optical axis inaccurate, improve the assembling yield, reduce and assemble man-hour.

[embodiment]

See also Fig. 2 to Fig. 5, the utility model digital camera lens barrel 20 comprises first housing 21 and second housing 22, this first,

second housing

21,22 is the half round post of symmetry, half cylindrical outer surface of difference tool (indicating) and

section

203 and 204, the two combination back becomes the tubular host body of lens barrel 20.Wherein two

sections

203 and 204 are fitted mutually, and this two semicolumns outside surface (not indicating) is not in conjunction with the cylindrical outer surface that forms this lens barrel 20 (indicating).The semicolumn outside surface of this first housing 21 (not indicating) tool screw thread 201, the a plurality of hole clippings 211 of tool on its section 203, the semicolumn outside surface of this second housing 22 (not indicating) tool screw thread 202, the a plurality of tenons 221 of tool on its section 204, these a plurality of hole clippings 211 match with a plurality of tenons 221 so that this first housing 21 and second housing 22 combine, the external thread 200 on the cylindrical outer surface (indicating) of this screw thread 201 and synthetic this lens barrel 20 of screw thread 202 kissings.

See also Fig. 3 and Fig. 4, this first housing 21 and second housing, 22 inside are respectively equipped with a plurality of and the integrated semi-circular interval 213 of housing and 223, and are corresponding respectively and cooperatively interact, first housing 21 and second housing 22 in conjunction with the time the corresponding annular space that is combined into.Adjacent second ring forms receiving space between the interval, and in order to accommodate lens, this annular space is then in order to the positioning lens spacing of (figure does not show).The number of lens in these a plurality of

semi-circular intervals

213 and 223 the number visor tube 20 and decide is provided with an interval between per two lens.The top 205 of this first housing 21 and

second housing

22 and 206 difference tools, one diameter are along funnel-

form half hole

212 and 222 of gradient thickness, its

bottom

207 and 208 is

half hole

214 and 224 of tool respectively, when first housing 21 combines with second housing 22, two funnel-forms,

half hole

212 and 222 is combined into a funnel-shaped apertures (not indicating), the size of this funnel-shaped apertures (indicate) is the size of these lens barrel 20 incidence holes, and lens in the fixed lens barrel 20 (scheming not show) can be played with 206 combination in this top 205.

Half hole

214 and 224 then is combined into the circular hole of a bottom.

See also Fig. 5, during assembling, lens (figure does not show) are installed in first housing 21, lens were not separated by with a plurality of intervals 213 between (figure shows), then that second housing 22 is relative with first housing 21, a plurality of hole clippings 211 of a plurality of tenons 221 of second housing 22 and first housing 21 fasten so that first housing 21 and second housing 22 are combined into lens barrel 20, the corresponding involutory spacings in a plurality of intervals 213 of a plurality of intervals 223 of second housing 22 and first housing 21 with lens (figure does not show) in the lens barrel 20 of location, again the internal thread 300 by the external thread 200 on lens barrel 20 outside surfaces (sign) and fastening assembly 30 mutually interlock make lens barrel 20 lock fastening assembly 30 internal fixation.
