In addition, the pressure ring 16 is sealed and fixed by the 18 which is applied to the flange 13 and the door of the lens barrel 12, and is coated with 18; the area is relatively small, so the firmness of the joint is weak. Lower, so that the reliability of the lens stack 10 is reduced and the service life is reduced. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a lens module that can easily adjust the lens. The lens module includes a lens barrel, a lens group, and a pressure ring. The lens set includes at least one lens that abuts the pressure ring, and the lens group is housed in the lens barrel. The pressure % is pressed against the lens. The lens of the pressure ring and the lens group that is in contact with the t% is provided with a mating engagement structure. The engagement structure is used to adjust the lens in the lens group. The lens module of the prior art is configured to provide a snap-fit structure on the lens and the pressure ring to engage with each other, so that the pressure ring can still be pressed against the lens by using The engagement structure adjusts the lens, thereby saving man-hours, simplifying the process, and reducing costs. [Embodiment] Referring to FIG. 2 and FIG. 3 together, a preferred embodiment of the lens module of the present invention includes a lens barrel 11A, at least one mirror 200914904, and a pressure ring 130. The lens barrel 110 is substantially cylindrical, and has a stepped hole 112'. The stepped hole 112 extends through the two ends of the lens barrel no. A first step 114 is formed on the inner peripheral wall of one end thereof and is adjacent to the first step 114. The second step 116. The lens group 120 includes a first lens 121 and a second lens 123. Preferably, the first lens m is a disk-shaped photonic lens that includes an optical portion 122 and a surrounding optical portion 122. Connection portion 124. A plurality of ribs 126 extending along the outer peripheral side of the lens are formed on the connecting portion 124 adjacent to the outer peripheral side of the lens 120, and the plurality of ribs 126 are evenly spaced apart from the connecting portion 124. On the outer edge of the surface. A slit 128 is formed between adjacent plurality of ribs 126. The second lens 123 is similar to the first lens 121 and includes an optical portion ι25 and a connecting portion 127. The first lens 121 and the second lens 123 of the lens group 120 are respectively received in the lens barrel 110. The first lens 121 is disposed in the lens barrel 11 by the connecting portion 124. On a step 114, the second lens 123 is seated on the second step 116 in the barrel 11 by its connecting portion. It will be appreciated that the lens set 12 can be a plurality of lenses, wherein each lens set 12 can include only a lens or a plurality of lenses can be included and is not limited to this embodiment. The pressure ring 130 is a ring that can cooperate with the lens 12 ,. The pressure ring 130 has a tapered hole 132 corresponding to the optical portion 122 of the lens i 2 , along the tapered hole 132 . The peripheral wall extends a convex ring 134 in the direction in which the diameter of the hole 200914904 increases. A plurality of protrusions 138 are disposed on the outer side wall of the pressure ring 13〇, and the protrusions 138 are extended in a radial direction away from the center of the pressure ring 130, and each of the protrusions 138 corresponds to A card 135 is disposed on a surface of one side of the lens 12 on which the rib 126 is formed, and the block 135 can be caught in the slot 128 of the lens 120. A plurality of grooves 136 corresponding to the ribs 126 on the lens 12 are formed between the adjacent bumps 138 on the pressure ring 13A. The pressure ring 13 is press-fitted onto the lens 120 in the lens barrel 110, wherein the tapered hole 132 of the pressure ring 130 corresponds to the optical portion 122 of the lens 12; the 13-inch card of the pressure ring The block 135 is opposite to the slot 128 of the lens 120 and snaps into the slot 128; the bump 138 formed on the pressure pin 130 abuts against the inner wall of the lens barrel 11 . When the lens 12 is placed in the lens barrel 11 , the pressure ring X30 is pressed onto the lens 12 , and can be inserted into the groove 136 of the pressure ring 130 by a certain adjustment tool. The pressure ring 130 is rotationally adjusted, and the pressure ring 13 is brought into the lens block 135 of the lens slot 128 to drive the lens 12 to adjust the lens. After the alignment and correction of the mirror #120 is completed, the (four) 14 turns can be filled between the (four) 13 inch convex ring 134 and the inner wall of the lens barrel, and the axial rubber 14Q can be used in the art. Any kind of point-bonding material, such as UV glue (•Μ0-, UV glue) or thermosetting glue, etc., is also filled with the _140 in the groove 136 of the ankle ring 130, so that the 200914904 calendar ring 130 and the The lens 120 is securely attached to the lens barrel. In the present embodiment, a snap-fit structure such as a slot and a card that can be engaged with each other is disposed on the lens 12 and the pressure ring 130, such as the slot 128 and the pressure ring 13 on the lens 120. Corresponding to the block 135, the lens i2 can be adjusted by the engaging structure when the pressure ring 130 is pressed onto the lens 〇2〇, thereby saving man-hours, simplifying the process, and reducing the cost. . In addition, a groove 365 is formed between the bumps 13 8 of the pressing ring 130, and the adhesive 14 粘接 bonding the pressing ring 130 and the mirror 11 〇 can be filled in the groove 136, thereby The bonding area of the adhesive 140 is increased to achieve the purpose of improving the bonding strength, thereby improving the reliability and the service life of the lens module. It can be understood that the engaging structure disposed on the lens 12 〇 and the pressure ring 13 也 can also be configured to provide a plurality of blocks on the lens 12 而 and to set corresponding positions on the pressure ring 130 . The slot is matched with the slot; the plurality of first blocks and the first slot may be alternately arranged on the lens 12〇, and the corresponding ring and the first block may be disposed on the pressure ring 13〇 The slot is corresponding to the second slot and the first block; so that the adjustment function of the lens can be realized after the pressure ring 13 is pressed onto the lens 120, thereby simplifying the process and shortening the working time. Will be low cost. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law. However, the above is only the preferred embodiment of the present invention.
