Problems solved by technology
However, in order to achieve the above-mentioned axial positioning and limit the rotation angle, the stop groove 102 must be provided on the fixed seat 1, and a plurality of screw holes 203' must be drilled in cooperation with the adjustment seat 2 for the The locking and positioning of the above-mentioned limiting member 203 not only requires many components and a complex structure, but also requires more processing procedures for the components.
[0005] In addition, in order to position the adjustment seat 2 relative to the fixed seat 1 in an axial direction, the cost of manufacturing and processing the stopper groove 102 on the fixed seat 1 will be relatively high.

Embodiment Construction
[0015] As shown in Fig. 3 and Fig. 4, the preferred embodiment of the adjustable lens device of the present invention includes a fixed base 10, a set of adjustment base 20 arranged outside the fixed base 10, and a screw mounted in the fixed base 10. The first mirror chamber unit 30 and a pair of second mirror chamber unit 40 that the first mirror chamber unit 30 is also installed in the fixing base 10 .
[0016] The fixing seat 10 is made into a hollow cylindrical shape, and has a peripheral wall 12 surrounding an axis L and defining an inner hole 11, a fixing portion 13 extending radially outward from the peripheral wall 12, and a plurality of ring devices. A positioning block 14 is disposed on the peripheral wall 12 and spaced apart from the fixing portion 13 , and a limiting portion 15 extends outward from a side end of the peripheral wall 12 along the axis L. As shown in FIG. The peripheral wall 12 has a first end portion 121, a second end portion 122 opposite to the first...

The invention relates to an adjustable lens device which comprises a fixing base, an adjusting base which is sleeved outside of the fixing base and a first mirror cell unit and a second mirror cell which are arranged on the fixing base. The fixing base is provided with a plurality of positioning blocks and a plurality of guiding grooves extending along the axial direction, the adjusting base has a ring groove used for leading the positioning blocks to be sleeved and positioned and a plurality of trigging grooves which are corresponding to the guiding grooves and extend in a helix way, and a plurality of guiding pieces of the second mirror cell unit are arranged in the guiding grooves and the trigging grooves in a penetrating way. The invention can lead the second mirror cell unit to reach a zoom aim by operating the adjusting base to correspondingly rotate with the fixing base and utilizing the cooperation of the trigging grooves and the guiding pieces.
Description
technical field [0001] The invention relates to a lens, in particular to an adjustable lens device mounted on optical equipment. Background technique [0002] As shown in Figures 1 and 2, there is an existing projector lens device with zoom and focus functions, which includes a fixed seat 1, a set of adjustment seats 2 arranged inside the fixed seat 1, a set of adjustment seats installed on the fixed seat 1 a front group mirror room unit 3 at the front end and a rear group mirror room unit 4 installed at the rear end of the fixing seat 1. The fixing seat 1 is in the shape of a stepped hollow cylinder, and has two sets of guide grooves 101 extending axially and a set of stop grooves 102 arranged on one side of the guide grooves 101 along the circumferential direction. The adjustment seat 2 is also in the shape of a stepped hollow cylinder, and is rotatably installed inside the fixed seat 1, and has two sets of first detent grooves 201 that extend spirally, and one set of fir...
