Example (b):

removable monocular telescope lens mounting structure is equipped with the light trap 1 that is used for seeing through the light signal on the monocular telescope objective casing front end terminal surface, installs lens 10 behind the light trap 1, and the round shell is installed usually to lens 10, install the interior ejector pad 2 that can push in the casing, the size and the casing inner wall of interior ejector pad 2 match and be cavity, and the mountable of interior ejector pad 2 is inside rather than sealed cooperation at the casing, and constitutes the cavity jointly with the casing, and the cavity comprises the light trap 1 of establishing on the casing and the shoulder hole of establishing on interior ejector pad 2, the shoulder hole includes first hole 3 and the second hole 4 with the centre of a circle, and the size and the lens 10 phase-match of first hole 3, and highly equals with the shell thickness of lens 10, and second hole 4 is located first hole 3 rear ends and diameter and is less than first hole 3, the shoulder hole sets up with the centre of a circle with the light trap. The end face of the front end of the inner pushing block 2 is completely matched with the inner end face of the shell where the light hole 1 is located in a sealing mode after the inner pushing block is installed, so that the lens 10 cannot slide in the radial direction or the axial direction.

The shoulder hole runs through interior ejector pad 2 front end terminal surface, still be equipped with spacing slot 5 along the axial on interior ejector pad 2's the side, and be equipped with the spacing track 6 that matches with it in the casing, lens 10 can be placed including in the first hole 3 that corresponds on ejector pad 2 during the installation, aim spacing track 6 and spacing slot 5 and can once only push into interior ejector pad 2 completely, laminate in the casing inner end face at light trap 1 place completely to first hole 3 place terminal surface, the centre of a circle of lens 10 corresponds with the centre of a circle of light trap 1, light signal sees through and lens 10 can not take place to rock and light signal when seeing through error-free, effectual.

Since the diameter of the light hole 1 is smaller than that of the first hole 3, when the lens 10 is placed in the first hole 3 of the stepped hole and is completely pushed to a designated position following the design of the limiting rail 6, the lens 10 is just aligned with and clamped with the light hole 1. Still be equipped with recess 7 on the terminal surface, recess 7 by the terminal surface circumference along protruding stretch out with the terminal surface is constituteed, uses waterproof glue to install the antifog piece 8 of unidimensional in the recess 7, reducible fog to the interference of lens visual angle. The side of the groove 7 is provided with a small outlet hole 9 for discharging possible seepage water.

In the scheme, the wall shell of the inner pushing block 2 is as light and thin as possible, the diameters of the first hole 3 and the second hole 4 are larger so as to reduce interference on sight, and the thickness of the second hole 4 is smaller according to actual adjustment and only serves as a lens in the first hole, but sight obstruction needs to be reduced.

Simultaneously, spacing track in this scheme can set up two, and 6 one of spacing track are established to cylindrical, establish to triangle-shaped for one, compare in only setting up a stability that strengthens more, and difficult emergence is rocked. The inner pushing block 2 pushes the lens 10 into the inner pushing block 2, and the outer wall of the inner pushing block 2 is in clearance fit with the inner wall of the shell. The rear end of the inner push block 2 is provided with an ocular, and the ocular and the inner push block can be screwed or fixed by a locking piece by a conventional means.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
