Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
With reference to fig. 1 to 4, a schematic structural diagram of an embodiment of the present invention is provided, including an inner guide groove 1, a guide boss 2, a fastening bolt 3, a bolt hole 4, a straight slot hole 5, a first dispensing groove 6, a second dispensing groove 7, and a glue storage groove 8; the inner guide groove 1 is positioned on the inner wall of the lens base, the guide boss 2 is positioned on the outer wall of the front end of the lens, the inner guide groove 1 and the guide boss 2 are parallel to the central axis of the lens, the fastening bolt 3 is a round-head refined countersunk head bolt, each end face of the fastening bolt 3 is a plane, the screw thread is not full thread, the upper half part of the screw thread is a non-thread part, the lower half part of the screw thread is a thread part, the bolt hole 4 is formed in the guide boss 2, the straight slot hole 5 is connected with the second glue dispensing slot 7, the first glue dispensing slot 6 and the second glue dispensing slot 7 are both annular slots, the first glue dispensing slot 6 is positioned at the top of the lens base, the second glue dispensing slot 7 is positioned on the outer wall of the lens base, the bottom end face of the second glue dispensing slot; the inner guide groove 1 is a rectangular groove, the guide boss 2 is a rectangular boss, the outer diameter of the thread of the fastening bolt 3 is slightly smaller than the groove width of the straight groove hole 5, the axial cross section of the second glue dispensing groove 7 is trapezoidal, and the axial cross section of the glue storage groove 8 is rectangular.
Wherein, when the lens and the lens base are assembled, firstly aligning the guide boss 2 with the inner guide groove 1, then arranging the lens into the lens base, at the moment, the outer wall of the front end of the lens is matched with the inner wall of the lens base, the guide boss 2 is matched with the inner guide groove 1, after the position is adjusted by sliding the lens, screwing the fastening bolt 3 into the bolt hole 4 through the straight slotted hole 5 and leading the lower end surface of the head part of the fastening bolt 3 to tightly press the bottom end surface of the second dispensing groove 7 and ensure that the lens does not shake, because the equipment of each manufacturer has slight difference, the position of the lens needs to be finely adjusted in later stage, the fastening bolt 3 needs to be unscrewed, when the position of the lens is finely adjusted, the fastening bolt 3 can slightly move in the straight slotted hole 5, the bolt 3 is fastened again after adjustment, and is respectively screwed in the first dispensing groove 6 and the second dispensing groove 7 and cured by a curing machine to play a role of reinforcement, some glue can flow in along the small gap between camera lens and camera lens base and store up gluey inslot 8 after the point is glued, avoid causing the pollution to image planes, it is profitable, the fixed terminal surface that mainly relies on the bolt head portion of camera lens position compresses tightly the gluey inslot face, leave certain clearance in the middle of direction boss 2 and interior guide way 1 in addition, consequently fastening bolt 3's packing force can not exert an influence to whole camera lens, the utility model has the advantages of simple structure, simple to operate is high in reliability, high accuracy and high straightness that hangs down have been guaranteed simultaneously, be fit for mill batch production.
The above description is only for the preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
