DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT - Referring to FIG. 1 to FIG. 4, an embodiment of the present invention provides a lens module 20 including a lens barrel 2〇1, a lens holder 2〇2, and an elastic 203. . ^ The lens barrel 201 is open at both ends and penetrates. The inside of the lens barrel 2〇1 is housed with elements such as a lens group, a spacer ring and a light-passing sheet (not shown). The lens barrel 201 includes, in order from the object side to the image side, a first thread portion 2〇11 and a shaft portion 2〇12 which are connected to each other. The threaded portion 2〇11 is provided with an external thread 2013. The outer diameter of the shaft portion 2012 is larger than the outer diameter of the outer thread 2〇13, whereby the vehicle portion 2〇12 has the first thread portion 2011 and the shaft portion 2012 connected thereto and oriented The first end surface of the object side 2〇14 ^ The lens holder 202 accommodates the lens barrel 2〇1, and the lens holder 2〇2 includes, in order from the object side to the image side, the second threaded portion 2〇21 connected to each other. Shaft hole portion 2〇22. The second threaded portion 2021 is provided with a screw: k2 (j23:: the internal thread 2023 forms a loose fit with the external thread 2013 of the lens barrel 2〇1 such that the internal thread 2023 and the lens barrel 2〇1 are externally The screw holes 2022 are not interlocked with each other. The shaft hole portion 2022 forms a shaft hole fit with the shaft portion 2〇12 of the lens barrel 201. The inner diameter of the shaft hole portion 2022 is larger than the internal thread 2〇23 The inner diameter, whereby the second threaded portion 2〇21 has a second end surface 2024 that connects the shaft hole portion 2022 and the second thread portion 2021 toward the image side. The spring 203 is a ring spring. The spring 2〇3 covers the first threaded portion 2011 of the lens barrel 201 and is disposed between the first end surface 2014 and the second end surface 2024. 098137008 Form No. A0101 Page 6 of 17 0982063442-0 201115203 [0012] Preferably, the spring 203 abuts against the first end surface 2014 and the second end surface 2024. Of course, the spring 2〇3 can also be associated with the lens barrel 2〇1. The first end face 2014 and the thread of the lens holder 202 abut against each other or with the thread of the lens barrel 2〇1 and the second end surface 2024 of the lens holder 202, as long as the bullet can be realized. The spring 203 can apply a force to the lens barrel 201 and the lens holder 202. Thus, when the spring 203 is compressed, the first end face 2〇14 and the second end face 2024 will be forced. Thus, the force of the spring 203 The lens barrel 2〇1 and the lens holder 202 can be interlocked with each other. Meanwhile, when the lens module 2 is adjusted, the force of the spring 203 can maintain the stability of the lens barrel 201 and the lens holder 202. The lens barrel 2 01 is prevented from swaying and causing the shaft to be tilted. The annular portion 2030 of the spring 203 is evenly opened with the elastic piece 2〇31. In the embodiment, the elastic piece is used. 2031 is opened in the same direction: Thus, when the spring 203 of the lens barrel 201 is compressed, it is formed to be equally distributed along the outer circumferential surface of the shaft portion 2011 of the lens barrel 2〇1 and is coupled to the lens module 2〇. The optical axis is parallel to the force. Of course, the elastic piece 2031 can also be opened in the opposite direction. [0014] In the embodiment, the elastic piece 2031 is provided with four pieces. Of course, three pieces or five pieces may be equally provided. 6 pieces are equally distributed as long as the outer circumferential surface of the shaft portion 2011 along the lens barrel 2〇1 is parallel to the optical axis of the lens module 2〇 [0015] In the present embodiment, the spring 203 is an annular spring. Of course, the spring 2〇3 may also be a spring plate as long as it can generate the shaft portion 2〇11 along the lens barrel 2〇1. The force of the circumferential surface equally distributed and parallel to the optical axis of the lens module 20 can be 098137008 Form No. 1010101 Page 7 / Total 17 Page 0982063442-0 201115203 [0016] Preferably, the shaft hole portion 2022 and the The shaft hole of the shaft portion 2012 is fitted with a transition fit or a clearance fit, and after the lens barrel 201 is engaged with the lens holder 202, the outer circumferential surface of the shaft portion 2012 of the lens barrel 201 and the lens holder The inner circumferential surfaces of the shaft hole portions 2022 of 202 are bonded to each other. Thereby, the shaft hole between the shaft portion 2012 and the shaft hole portion 2022 has a guiding effect, and the relative rotation between the lens barrel 201 and the lens holder 202 is easily realized, and the lens barrel 201 and the lens holder 202 are easily controlled. The torque/torque between the two facilitates the assembly of the lens barrel 201 and the lens holder 202 as well as the focusing of the lens module 20. [0017] The external thread 2013 of the lens barrel 201 is loosely engaged with the internal thread 2023 of the lens holder 202. Thus, there is no thread tight fit between the lens barrel 201 and the lens holder 2〇2. The phenomenon of different or uneven adhesion is used to avoid the occurrence of biting in the thread matching. [0019] [0019]
優選地’所述外螺紋2013與所述内螺紋2023的螺紋圈數 為2~3圈，由此，既可容易地實現外蜾紋201 3與内螺紋 2023的松配合’又便於鏡筒201與鏡赛202的加工。Preferably, the number of turns of the external thread 2013 and the internal thread 2023 is 2 to 3 turns, whereby the loose fit of the outer ridge 201 3 and the internal thread 2023 can be easily achieved, and the lens barrel 201 is facilitated.

[0020] Further, the end of the lens barrel 2〇1 facing the object side is provided with a groove 2017 for cooperating with a focus ring (not shown) for performing the lens through the focus ring. Focusing of the module 20. [0021] When the lens module 20 is assembled, the spring 203 is inserted into the first threaded portion 2011 of the lens barrel 201 and abuts against the first end surface 2014, and then the jig and the card slot 098137008 are used to form the nickname A0101. / Total 17 pages 0982063442-0 201115203 [0023] [0023] Ο 〇2016 cooperates with 'fixing the lens barrel 201, then inserting the lens holder 202 into the lens barrel 201 and rotating it properly' until the lens barrel 2〇1 and the lens holder 2 〇 2 is assembled in place. When the lens module 20 is subjected to focusing, since the uniform torque/torque between the lens barrel 2〇1 and the lens holder 2〇2 and the guiding action of the shaft hole matching are performed, the focusing can be easily performed. Further, due to the action of the spring 2〇3, it is possible to ensure the stability of the lens barrel 201 and the lens holder 2〇2 during the focusing process. Compared with the prior art, the lens barrel and the lens holder in the lens module of the present invention are matched by loosely fitting and non-locking threads, and the elastic element is used to lock the lens barrel and the lens holder. It is different from the way in which the lens barrel and the lens holder are closely matched and locked by the thread in the conventional lens module. Therefore, the lens module of the present invention has the following advantages: First, the locking force is not formed by the threaded engagement between the lens barrel and the lens holder. Therefore, there is no difference in the locking force between the screws in the conventional thread matching. The uniform phenomenon can avoid the focusing process being difficult to adjust due to the different or uneven locking force. The second process of assembling the lens barrel and the lens holder, the loosely fitting of the thread enables easy adjustment between the lens barrel and the lens holder, so that the phenomenon that the lens barrel and the lens holder are stuck with each other due to the incomplete positioning of the thread is less likely to occur. Quickly assemble the lens barrel module. [0024] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law.
