Description

[0001] DOT SIGHTING DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dot site apparatus, and more particularly, to a dot site apparatus capable of improving the aiming accuracy by preventing a minute dot movement of a dot occurrence unit by an assembly tolerance between members.

In the case of general firearms, it is very important to aim at the alignment of the line of sight made of the scale, the latch, and the target (target), aiming the gun straight at the target, and aiming quickly so that the target, scale, It is important.

However, such a line-of-sight alignment is liable to be disturbed by a small vibration or tremor, and is disadvantageous in a rapid aiming required in a near or imminent situation. In other words, this type of aim shooting method requires complicated process and time such as target acquisition and confirmation, sight line alignment, and aiming. Also, since the scale and the scale itself are very small, they are sensitive to small tremors. If you care too much about line-of-sight alignment, your eyes will be focused on the scale and the scale itself rather than on the target or the front.

A telephoto aimer, such as a rifle scope, has been proposed to improve accuracy while resolving the hassle of alignment. However, in the case of a telephoto zoom, there is an advantage of accurately aiming a target at a distance, but since a telephoto lens is used, the zoom lens is sensitive to small shakes as the magnification of the lens increases.

In order to solve the above problem, it is necessary to adopt a no-magnification lens and to simply match the dot and the target (target) within the effective aperture of the sphygmomanometer while eliminating the complicated line of sight composed of the scale, An optomechanical optical sighting device such as an optical dot sighting device has been proposed. This no-magnification optical syringe is characterized by its ability to be simple and fast to aim at, and it has a very useful advantage in an imminent situation or in a short distance where a rapid response is required. That is, even if there is a dot (dot, a light spot) which is a virtual image of the dot on the spot at any position within the effective aperture of the sneaker, the shot can be rapidly moved so that the dot coincides with the target, And it is possible to shorten the time required for aiming and to minimize disturbance of peripheral vision and situation confirmation due to aiming.

The conventional dot site is adjusted so that the dot, which is the virtual image of the dot mark and the impact point, exactly coincide with each other through the zero point adjusting mechanism that finely adjusts the position of the dot mark generating unit vertically and horizontally. However, since the zero point adjusting mechanism is complicatedly assembled with a large number of parts, there is a problem in that the accuracy of aiming is low as the position of the dot generating part is arbitrarily moved within the assembly tolerance between the members due to the impact shock or external impact.

Specifically, the first adjusting screw 121 of the first adjusting part 120 is disposed in the X-axis direction and is rotatably installed in the housing 10, and the first adjusting screw 121 of the first adjusting part 120 The reference block 122 is in contact with the moving block 111 through the first guide surface 122a while being screwed to the first adjusting screw 121. [ Therefore, when the first adjusting screw 121 is rotated, the first reference block 122 advances or retracts in the X-axis direction according to the rotating direction of the first adjusting screw 121, Can be adjusted in the X-axis direction.

Since the other side surface of the moving block 111 is elastically pressed and supported by the elastic pressing part 140, the moving block 111 is in contact with the first reference block 122 of the first adjusting part 120 The state can be maintained.

The pressing block 141 of the elastic pressing part 140 is disposed on the other side of the moving block 111 through the inclined surface 141a and the pressing block 141 is pressed by the elastic member 142 in the X- And a rear end of the elastic member 142 is supported by a screw 143 screwed to the housing 10.

In particular, since the first guide surface 122a and the slope surface 141a each have a slope with respect to the Y axis, the moving block 111 positioned between the first guide surface 122a and the slope surface 141a is elastically pressed Axis direction to the third guide surface 132b of the second adjusting portion 130 by the elastic force of the first guide portion 140. [ Accordingly, in the process of adjusting the position of the moving block 111 in the X-axis direction by using the first adjusting unit 120, the moving block 111 is in a state of being in close contact with the third guide surface 132b in the Y- .

The first adjusting screw 121 of the first adjusting part 120 is mounted on the head part provided at the rear end of the first adjusting screw 121 in a state where the first adjusting screw 121 is rotatably inserted into the housing 10 And the other side is supported by the stop ring 161 to limit the axial movement of the first adjustment screw 121. [ An oval ring 162 made of an elastic material interposed between the head part and the housing 10 allows the rainwater or the like to flow into the housing 10 through the space between the first adjusting screw 121 and the housing 10 Can be prevented.

Since the pressing piece 163 for preventing any rotation of the first adjusting screw 121 is disposed in the housing 10, it is possible to prevent the X-axis position of the dot- can do. Since the rear end portion of the pressing piece 163 is elastically pressed by the spring 164 in a state where the front end portion is in contact with the concave and convex portion 121a formed on the outer peripheral surface of the head portion of the first adjusting screw 121, It is possible to restrict any rotation of the adjusting screw 121. [ The rear end of the spring 164 is supported by a fixing screw 165 screwed to the housing 10 so that the fixing screw 165 is rotated to adjust the distance between the fixing screw 165 and the pressing piece 163 The elastic force of the spring 164 can be controlled.

The first reference block 122 is resiliently supported in the X-axis direction by the elastic pressing portion 140 so that the pressing force acts on the rear end of the first adjusting screw 121. Therefore, the first reference block 122 And the first adjusting screw 121, it is possible to prevent the first reference block 122 from moving finely in the X-axis direction.

7, since the inclined surface 141a located between the pressing block 141 and the moving block 111 has a slope with respect to the Z-axis, the moving block 111 is elastically pressed 140 to the second guide surface 132a of the second adjuster 130 in the Z-axis direction. Therefore, in the process of adjusting the position of the moving block 111 in the X-axis direction by using the first adjusting unit 120, the moving block 111 is in a state of being in close contact with the second guide surface 132a in the Z- .

That is, the moving block 111 is pressed in the Y-axis direction and the Z-axis direction by the inclined surface 141a provided on the contact surface with the press block 141, so that the second guide surface 132 of the second reference block 132 132a in the Z-axis direction, and the third guide surface 132b is held tightly in the Y-axis direction. Accordingly, it is possible to prevent the moving block 111 from arbitrarily moving in the Y-axis and Z-axis directions in the process of adjusting the position of the moving block 111 in the X-axis direction by using the first adjusting unit 120.

8, the first coupling portion 111a provided in the moving block 111 of the dotted-eye table generating portion 110 is coupled to the second reference block 132 of the second adjusting portion 130, And the second reference block 132 is screwed to the second adjusting screw 131 provided in the housing 10 so as to be axially rotatable in the Z axis direction . Accordingly, when the second adjusting screw 131 is rotated, the second reference block 132 moves up or down in the Z-axis direction in accordance with the rotating direction of the second adjusting screw 131, The direction position is adjusted.

In this case, since the first guide surface 122a provided on the contact surface between the moving block 111 and the first reference block 122 is formed in parallel to the Z axis, by using the second adjusting unit 130, The position of the moving block 111 in the X axis direction can be kept constant in the process of adjusting the Z axis position of the moving block 111. [

The second reference block 132 is elastically supported in the Z-axis direction by the spring 150. Therefore, the second reference block 132 is pressed by the second reference block 132 and the second adjusting screw 131 within the threaded engagement tolerance of the second reference block 132 and the second adjusting screw 131, 132 can be prevented from moving finely in the Z-axis direction.

In addition, since a plurality of springs 150 are arranged radially with respect to the second adjusting screw 131, the second reference block 132 can be moved in the process of raising and lowering the moving block 111, 131 can be balanced without any inclination in either direction (see FIG. 6).

The second adjusting screw 131 is restricted in axial movement by the stop ring 161 and the O-ring 162 as well as the first adjusting screw 121, 164 and the fixing screw 165. Since the operation is the same as that of the first adjusting screw 121, a detailed description thereof will be omitted.

According to this embodiment, the moving block 111 of the dotted-eye mark generating section 110 is moved in the Y-axis direction by the elastic pressing section 140 in the X-axis direction, And the third guide surfaces 132b in the axial direction. Accordingly, since the movement block 111 can be prevented from moving finely within the assembly tolerance between the members, the zero point adjustment of the dotted-eye mark generating unit 110 can be performed by the impact generated at the triggering of the shooting or the external impact applied to the dot site It is possible to prevent the setting position from being changed, thereby improving the aiming accuracy of the dot site. In addition, since the moving block 111 of the dotted-eye mark generating unit 110 can be elastically supported in three axial directions by one elastic member 142, it is advantageous in downsizing and lightening the device.

The first adjusting screw 121 and the first reference block 122 and the second adjusting screw 131 and the second reference block 132 are respectively disposed in the axial direction in the assembly tolerance for the engagement of the male and female threads. , Which serves as a factor for lowering the precision of aiming.
