Dot sight

A dot sight, comprising:

• a sight mount, wherein a first chamber extending along an axial direction of the sight mount is formed in the sight mount, and an end of the first chamber close to an object side communicates with the outside;
• a sight frame provided at a circumferential side of the sight mount close to an eye side, wherein a second chamber penetrating through the sight frame along an axial direction, and a through opening communicating the second chamber and the first chamber are formed in the sight frame;
• a light source member provided at the end of the first chamber close to the object side, and configured to emit light to the eye side, wherein an axial position of the light source member relative to the sight mount is adjustable;
• a collimator lens set provided in the first chamber, and provided at a side of the light source member close to the eye side;
• a reflector provided in the first chamber, and corresponding to the through opening;
• and
• a beam splitter prism provided in the second chamber, wherein the beam splitter prism comprises a first prism and a second prism cemented to each other, and a reflective film is provided on a cemented plane of the first prism and the second prism,
• wherein the dot sight further comprises an inner tube provided at the end of the first chamber close to the object side, and a first adjustment mechanism provided at an end of the inner tube close to the eye side;
• a first ball head is provided convexly at a circumferential side of the inner tube;
• a first ball socket is provided concavely on a wall of the first chamber;
• the first ball head is hinged to the first ball socket;
• the first adjustment mechanism is configured to drive the inner tube to rotate;
• a third chamber penetrating through the inner tube along an axial direction is formed in the inner tube;
• the light source member is provided in the third chamber;
• and an axial position of the light source member relative to the inner tube is adjustable.

• and
• a beam splitter prism provided in the second chamber, wherein the beam splitter prism comprises a first prism and a second prism cemented to each other, and a reflective film is provided on a cemented plane of the first prism and the second prism,
• wherein the end of the first chamber close to the object side is sequentially provided with a second mounting hole and a second through hole from the object side to the eye side;
• and
• the dot sight further comprises a second adjusting rod and a second pressure ring;
• the second adjusting rod is rotatably provided in the second mounting hole;
• the second pressure ring is connected to an end of the sight mount close to the object side, and restricts the second adjusting rod from moving axially along the second mounting hole;
• an end of the second adjusting rod close to the eye side is provided with an axially extending second connecting hole;
• the light source member comprises one end connected to the second connecting hole, and the other end penetrating through the second through hole;
• and the second adjusting rod in rotation drives the light source member to move axially relative to the second through hole.

• and
• a collimator lens set provided in the first chamber, wherein the collimator lens set comprises a first lens, a second lens, and a third lens sequentially arranged and having a refractive capability;
• the first lens and the second lens are provided between the light source member and the reflector;
• the third lens is provided between the second lens and the beam splitter prism;
• the first lens and the third lens are fixed relative to the sight mount;
• and an axial position of the second lens relative to the sight mount is adjustable.
