Please refer to Fig. 1, one embodiment of the aiming correction mechanism of the present invention is a collimator 20, including a body 201, an objective lens group 202, an upright lens barrel 204, an eyepiece group 206 and a correction mechanism 10, Wherein the objective lens group 202 and the eyepiece group 206 are respectively arranged on the two ends of the body 201, and the upright lens barrel 204 is arranged between the objective lens group 202 and the eyepiece group 206, so that the objective lens group 202, the upright lens barrel 204 and the eyepiece group 206 are arranged along the An optical axis OA is arranged sequentially. The correcting mechanism 10 is disposed on the main body 201 , and the adjusting element 19 of the correcting mechanism 10 abuts against the upright lens barrel 204 . To perform bounce correction, the user rotates the adjustment cover 11 of the correction mechanism 10 to move the adjustment element 19 along the axis L to correct the bounce point. The details will be described below. It should be noted that the correction mechanism 10 can be a height correction mechanism or a windage correction mechanism.

Please refer to Figures 2 and 3 at the same time. In addition to the aforementioned adjustment cover 11 and adjustment element 19, the correction mechanism 10 of one embodiment of the present invention further includes a first transmission unit 16, a second transmission unit 12, and a display unit. 17 and a base unit 13.

The base unit 13 is fixed on the body 201 of the sight 20 . The base unit 13 includes a sleeve upper cover 131, a sleeve 132 and a base 133, wherein the base 133 is arranged on the body 201 of the sight 20, the sleeve 132 is arranged on the base 133, and the sleeve upper cover 131 is arranged One end of the sleeve 132 away from the base 133 .

The display unit 17 includes an annular body 171 sleeved on the sleeve 132 of the base unit 13. The inner peripheral wall of the annular body 171 is provided with internal threads (not shown), and the sleeve 132 An external thread (not shown) is provided on the outer peripheral wall, and the external thread and the internal thread can cooperate with each other, so that the annular body 171 can rotate relative to the fixed sleeve 132 . In addition, marks 172 are provided on the outer surface of the annular body 171. In this embodiment, the marks 172 are a plurality of parallel scale lines, and the distance between these scale lines is equal to the lead of the internal thread, so that the ring body When 171 rotates one turn relative to the sleeve 132, it also moves along the axis L by a distance (that is, the distance between the scale marks), so the mark 172 can also be called a circle number mark.

The sleeve upper cover 131 has a first central hole 138 , the sleeve 132 has a second central hole 139 , and the base 133 has a third central hole 135 . The second transmission unit 12 is disposed on the base unit 13 by passing through the first center hole 138 and the second center hole 139 , and can rotate relative to the base unit 13 . Specifically, the second transmission unit 12 includes a rotating cylinder upper cover 121 and a rotating cylinder 122, wherein the rotating cylinder 122 is rotatably disposed in the sleeve 132, and the rotating cylinder upper cover 121 is disposed on the rotating cylinder 122 away from One end of the seat body 133 . The rotating cylinder 122 has an adjustment hole 124, the adjustment element 19 is arranged in the adjustment hole 124, and passes through the seat body 133 through the third central hole 135, so as to extend to the inside of the main body 201 of the sight 20 and abut against the erect mirror Cartridge 204. It should be noted that the outer peripheral wall of the adjustment member 19 has an external thread (not shown), and the inner peripheral wall of the adjustment hole 124 has an internal thread (not shown), and the external thread and the internal thread can cooperate with each other. . Also, the cross-sectional shape of the third central hole 135 of the seat body 133 is non-circular and corresponds to the cross-sectional shape of the adjustment element 19. If it is set in this way, the adjustment element 19 will not be in contact with the base unit 13 when the base unit 13 is fixed. The seat unit 13 is relatively rotated. Therefore, when the rotating cylinder 122 of the second transmission unit 12 rotates relative to the base unit 13 , the adjustment element 19 will only move axially relative to the base unit 13 . In addition, when the second transmission unit 12 rotates relative to the base unit 13, the rotating cylinder 122 cannot move axially relative to the base unit 13 (that is, cannot move along the axis L) because it is restricted by the base unit 13. ).

The adjustment cover 11 is fixed on the second transmission unit by a plurality of adjustment cover fixing parts 311 The upper cover 121 of the rotating cylinder of the unit 12, so that the adjustment cover 11 can drive the second transmission unit 12 to rotate relative to the base unit 13 when the adjustment cover 11 rotates. On the other hand, a plurality of elongated grooves 118 are disposed on the inner surface of the adjustment cover 11 , and these grooves 118 are all parallel to the axis L. As shown in FIG. The first transmission unit 16 includes at least one column 161 fixedly connected to the annular body 171 of the display unit 17 and extending away from the axis L to enter the groove 118 . In this embodiment, the first transmission unit 16 includes three cylinders 161 , and these cylinders are arranged around the axis L at intervals of 120 degrees, but the invention is not limited thereto.

At least one message display part 117 is further provided on the adjustment cover 11, wherein the message display part 117 can be a through hole or a transparent area, and the user can observe the change of the scale line through the message display part 117. In this embodiment The three message display parts 117 are through holes and are arranged around the axis L at intervals of 120 degrees, but the present invention is not limited thereto.

When shooting, the user can rotate the adjustment cover 11 to perform bounce compensation. At this time, the adjustment cover 11 will drive the second transmission unit 12 to rotate relative to the base unit 13, and then drive the adjustment element 19 to move axially relative to the base unit 13. The angle of the upright lens barrel 204 in the height or windage direction can be adjusted, so as to achieve the purpose of impact compensation. On the other hand, when the adjustment cover 11 rotates, it can also drive the display unit 17 to rotate together through the first transmission unit 16, because the annular body 171 of the display unit 17 is screwed to the sleeve 132 of the base unit 13, and the second A transmission unit 16 is restricted in the groove 118, so that the annular body 171 not only rotates around the sleeve 132, but also moves along the axis L. Please refer to FIG. 4, at this time, the user can display the Part 117 to observe the change of the scale line, so the display unit 17 can also be called the number of turns display unit. As mentioned above, the mark 172 is a plurality of parallel scale lines, and the distance between these scale lines is equal to the lead of the inner thread of the ring body 171, so when the ring body 171 rotates one circle relative to the sleeve 132, the It will also move along the axis L at the interval of one scale line. In other words, every time the adjustment cover 11 rotates one turn, the scale line displayed on the message display part 117 will increase by one. For example, compared with Figure 4 in Figure 5, the message The scale lines displayed on the display portion 117 have increased by five, which means that the adjustment cover 11 has rotated five times.

When the user removes the adjustment cover fixing part 311 and then disassembles the adjustment cover 11 to reset the impact point to zero, the annular body 171 of the display unit 17 can be rotated to the lowest position, which is the zero position of the display unit 17. Then put the adjustment cover 11 back and lock the adjustment cover fixing part 311, that is, the zero-setting of the display unit 17 is completed.

In the above embodiment, the mark 172 is a plurality of parallel scale lines, but it can be understood that if the scale lines are changed to numbers (such as 1, 2, 3, etc.), the number of rotations of the adjustment cover 11 is directly displayed, which is very important for the user It will be easier to identify, which also belongs to the scope of the present invention.
