Description of the Invention: • Technical Field of the Invention [0001] The present invention relates to the field of optical systems, and more particularly to a lens barrel and a camera module using the same. [Prior Art] [0002] With the development of camera technology, camera modules are widely used in camera devices for various purposes, and camera modules are combined with various portable electronic devices such as mobile phones and computers to obtain many consumers. Favored. The phase sensor module usually includes a lens barrel and a plurality of optical components received in the lens barrel. _ In the assembly process of the camera module, the optical component is usually dispensed into the lens barrel by a dispensing method. This method often causes the adhesion between the lens barrel and the optical element to be easily detached from the lens barrel due to deterioration of the knee, uneven coating of the glue, and a small contact area between the optical element and the lens barrel. It not only reduces the assembly yield between components, but also makes the camera module easy to fail. In addition, during the dispensing process, the glue is also easily leaked from between the inside of the lens barrel and the side of the optical element, and then flows onto the upper surface of the optical element or other optical elements adjacent to the optical element, thereby It affects the imaging quality of optical components, which in turn reduces the quality of camera module imaging. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a lens barrel in which a spot material can be fixed without a spot material, and a camera module having the lens barrel. The rigid-type lens barrel includes a hollow body portion. The inner surface of the hollow body portion encloses a forming-receiving chamber. The hollow body portion has a second end opposite to the first end of the first 0992045910-0 099126174 form apostrophe A0101 page 3 / 15 page 201207459 end. The first end is formed by the hollow body portion extending toward the inside of the lens barrel in a circumferential direction of the hollow body portion to form a lip portion. The lens barrel further includes a cover portion that is integrally coupled to the second end of the hollow body portion by a snap fit. A camera module includes a lens barrel and at least one optical component. The lens barrel includes a hollow body portion. The hollow body portion includes a first end and a second end opposite the first end. The inner surface of the hollow body portion encloses a cylindrical receiving cavity. The receiving cavity is configured to receive the at least one optical component. The first end is formed by the hollow body portion extending toward the inside of the lens barrel in a circumferential direction of the hollow body portion to form a lip portion. The lens barrel further includes a cover portion. The cover portion is integrally coupled to the second end of the hollow body portion by a snap fit, and the at least one optical member is pressed between the cover portion and the lip portion. [0007] The hollow body portion and the cover portion of the lens barrel provided by the embodiment of the present invention are integrally integrated by the snapping manner, so that at least one optical component can be pressed between the cover body portion and the lip portion. , eliminating the dispensing process. Due to the tightness of the cover portion and the limitation of the lip portion, the optical component in the lens barrel is not easily detached from the lens barrel, and the camera module having the lens barrel is not easily damaged and has a long life. In addition, since no dispensing is required, the surface of the optical component is not covered by the glue, and the image quality of the camera module having the optical component is also high. [0008] Referring to FIG. 1 , FIG. 2 and FIG. 3 , a camera module 100 provided by an embodiment of the present invention includes a lens barrel 10 , a first optical element 20 , a second optical element 30 , and a second Three optical elements 40, mirror mounts integrally coupled to the lens barrel 10, 099126174 Form No. A0101 Page 4 / Total 15 pages 0992045910-0 201207459 [0009] [0010] Ο [0011]
