Description of the new type: [Technical field to which the new type belongs] This creation is about a kind of lens barrel device, especially for a camera. [Prior technology] Miscellaneous mosquito mirrors. The lens imaging quality is a key factor that affects the camera imaging quality. ^ It is composed of a plurality of mirror ships. Each-Lai device includes-a lens barrel and Wei Wei, separated-divergent, in order to make the mirror job parameters set in optical design. = Sexuality is one of the important factors to ensure the quality of lens imaging. Accurately know the generation of the distance between the lenses of the lens barrel device using the following two stand-alone & 2 ϊ =, ί connected to the lens 3-side set-flange 1 to make each _ of the two Figure 'Installation room_2' between each lens 4 is used to generate the distance between the mirrors 4. However, using the above-mentioned first method to generate 22 = 'transparent f / structure between each lens 3 will be very complicated and easy to produce ghost and stray light; the flange 1 is too large, it is easy to make the lens 3 during the injection molding process. Defects such as uneven injection and insufficient filling occur. The second method described above is used to generate the points between the lenses 4, the parts are fresh, and the assembly _ produces an error _, which affects the amount of mirror sugar; the assembly takes time and the cost is high. '' In view of this, it is necessary to provide a lens unit with a lens structure that is easy to disassemble, easy to assemble, and low in cost. [New content] The purpose of this creation is to provide a tube device with a simple lens structure, convenient assembly, and low cost. The creative lens barrel device includes a lens barrel and a lens module. The lens barrel is cylindrical and is provided with internal threads. The lens module is provided with external threads and is placed in the lens barrel. The externally threaded disc fits the internal thread described above. '' Compared with the prior art, the lens barrel device of this creation has higher accuracy, convenient adjustment of the distance between assembly and penetration, and lower cost. [Embodiment] The creative lens barrel device includes-a lens barrel 1 (), a three lens 12 and a three ring 12 (). The three lens 12 M264510 and the three ring 120 are placed in the lens tube ιo. The lens barrel 10 is cylindrical and is provided with an internal thread 100 therein. The mirror I2 is sleeved in the sleeve 衮 120, and is connected with the collar ⑽ to form an integrated lens module; the collar 120 is provided with an external thread 124, and the external thread 124 is combined with the internal thread. The collar! 20 includes a surface 126, which is provided with a recess 128 and the recess 128 are all distributed on the collar 120. When assembling the lens barrel device, the recess 120 is used to cover the three The lenses 12 are screwed into the lens barrels 10 and 10 respectively. In this way, the three pitches can be assembled into a fine copper distance by means of a screwdriver assembly, and the outline distance can be adjusted. 々 It can be understood that the «12〇 can be omitted, and the thread 124 is directly processed on the lens η. If a mirror with a thread is formed in a thin manner by injection; the recessed position is hidden in the collar ⑶ It can be set on the surface of the lens near the circumference The number of the lenses 12 is not limited to three, and may be any number of two or more; the depression 128 may be replaced by a protrusion, the mirror ^ the depression 128 may also be omitted, and the Γ μ is operated by means such as vacuum adsorption. "This creation complies with the requirements for new patents, and a patent application is duly filed according to law. However, with the help of good practice, those who reduced the cost of the new art, in the support of this style i single money, _including the sole of the towel_.
