Detailed Description
The present utility model will be described in detail with reference to fig. 1 to 4.
The utility model relates to a cat eye lens with an improved structure, which comprises a lens cone 1, wherein an installation seat 2 is integrally formed at the front end of the lens cone 1, the installation seat 2 is communicated with the lens cone 1, and a first plastic lens 21 is fixedly arranged in the installation seat 2; the lens cone 1 is internally provided with a second plastic lens 11, a glass lens 12, a third plastic lens 13 and a fourth plastic lens 14 in sequence from top to bottom, a first space ring 15 and a second space ring 16 are sequentially arranged between the second plastic lens 11 and the third plastic lens 13, the glass lens 12 is arranged on the second space ring 16, the middle part of the second space ring 16 is provided with a first annular platform part 161 for stably assembling the glass lens 12, and the glass lens 12 is provided with a second annular platform part 121 matched with the first annular platform part 161; the middle part of the tail end of the lens barrel 1 is also provided with an optical filter 17.
The lens barrel 1 is integrally formed with the mounting seat 2 for fixedly mounting the first plastic lens 21, and an end cover is not required to be assembled at the front end of the lens, so that the production cost of the lens is effectively reduced; secondly, the inventor has further optimized the assembly of the glass lens 12 in the lens cone 1, and the second space ring 16 and the glass lens 12 are respectively provided with annular platform parts which can be mutually abutted to realize the stable assembly of the glass lens 12, so that the imaging of the cat eye lens is stable.
