Abstract

The sight includes a main body, a regulating bolt movably joined to the main body, a securing bolt fixed to the regulating bolt, a regulating cover covering the regulating bolt and movable between a first position and a second position with respect to the regulating bolt, a first magnet disposed on the regulating cover, and a second magnet disposed on the regulating bolt and corresponding to the first magnet. The regulating cover is movable with respect to the regulating bolt when the regulating cover moves away from the second position. The regulating cover abuts the securing bolt and is rotatable with respect to the regulating bolt when the regulating cover moves to the first position. The regulating cover engages the regulating bolt when the regulating cover moves to the second position. The regulating cover is maintained in the second position through attraction of the first magnet and the second magnet.

Claims

1. A sight, comprising:

a main body;

a regulating bolt movably joined to the main body;

a securing bolt fixed to the regulating bolt;

a regulating cover covering the regulating bolt and movable between a first position and a second position with respect to the regulating bolt, wherein the regulating cover is movable with respect to the regulating bolt when the regulating cover moves away from the second position, the regulating cover abuts the securing bolt and is rotatable with respect to the regulating bolt when the regulating cover moves to the first position, and the regulating cover engages the regulating bolt when the regulating cover moves to the second position;

a first magnet disposed on the regulating cover; and

a second magnet disposed on the regulating bolt and corresponding to the first magnet, wherein the regulating cover is maintained in the second position through attraction of the first magnet and the second magnet.

2. The sight as claimed in claim 1, wherein the regulating cover comprises a first ring gear, the regulating bolt comprises a second ring gear, and the regulating cover engages the regulating bolt through engagement of the first ring gear and the second ring gear when the regulating cover is in the second position.

3. The sight as claimed in claim 2, wherein the first ring gear is formed on an inner surface of the regulating cover, and the second ring gear is formed on an outer surface of the regulating bolt.

4. The sight as claimed in claim 1, wherein the regulating cover comprises an abutting portion, the securing bolt comprises a head, and the abutting portion is disposed between the head and the regulating bolt, the abutting portion abuts the head when the regulating cover moves to the first position.

5. The sight as claimed in claim 1, wherein the first magnet is annular.

6. The sight as claimed in claim 5, wherein the second magnet is annular.

7. The sight as claimed in claim 1, wherein the second magnet is annular.

8. The sight as claimed in claim 1, wherein the first magnet is disposed on a lower surface of the regulating cover.

9. The sight as claimed in claim 8, wherein the second magnet is disposed on an upper surface of the regulating bolt.

10. The sight as claimed in claim 1, wherein the second magnet is disposed on an upper surface of the regulating bolt.

11. The sight as claimed in claim 1 further comprising a base which is fixed to the main body and comprises a screw hole, wherein the regulating bolt screws into the screw hole so that the regulating bolt is movably joined to the base.

12. The sight as claimed in claim 1 further comprising a magnification regulating unit disposed in the main body, wherein the regulating bolt moves to move the magnification regulating unit.
