Description

Technical Field

[0001] The invention relates to the technical field of aiming devices, in particular to a trajectory adjustment tower and a sighting scope having the same. Background Art

[0002] Most traditional internal adjustment ballistic adjustment structures directly use a spring, a ball, and an outer ring gear. Specifically, the ball is similar to a bullet, and includes a flat end and a pointed end. The spring supports the flat end of the ball, and the tip of the ball is stuck in the outer ring gear. When twisting, the ball rotates, and the tip scrapes on the outer ring gear, realizing the gear feeling when rotating.

[0003] The above structure has at least the following defects: First, if the outer ring gear is made of a soft material, the marble or the teeth of the gear may wear out with long-term friction, and the gear position will gradually become unclear and lose its feel, which is not conducive to the adjustment and use of the scope; second, because the marble occupies a certain length, the height of the trajectory adjustment structure is relatively long. In order to have a larger stroke of the telescopic screw, the overall height is increased, resulting in the bulge outward when installed on the scope, blocking the field of view and affecting the use; third, if the traditional structure wants to improve the accuracy of each gear position, it is necessary to increase the outer diameter of the entire gear and increase the number of teeth. The increase in the outer diameter structure will affect the appearance and integrity. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a ballistic adjustment tower and a sight having the same, which can effectively solve the problem of loss of gear sense due to long-term use and wear, and at the same time make the telescopic screw have a larger stroke or shorten the overall height dimension.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A trajectory adjustment tower comprises an adjustment tower base; an upper toothed ring fixed on the body of a sight and located above the adjustment tower base, and having a plurality of first teeth at its lower end; an adjustment dial rotatably arranged in the adjustment tower base, and the upper end of the adjustment dial passes through the upper toothed ring; a telescopic screw threaded on the lower end of the adjustment tower base, the telescopic screw movably connected to the lower end of the adjustment dial, and the telescopic screw can move up and down relative to the adjustment dial; a lower toothed ring movably sleeved on the outer side of the adjustment dial, the lower toothed ring is relatively fixed to the adjustment dial in the horizontal direction through a limiting structure, and the upper end of the lower toothed ring has a plurality of second teeth; an elastic element is arranged on the outer side of the adjustment dial and located at the lower end of the lower toothed ring, the elastic element presses against the lower toothed ring so that the lower toothed ring is meshed with the upper toothed ring.

[0007] The above pointer has at least the following beneficial effects: when the adjustment dial rotates, the lower toothed ring is driven to rotate. The lower toothed ring meshes with the upper toothed ring under the action of the elastic element, so that the rotation has a gear sense, replacing the original spring, ball and outer ring gear structure, effectively solving the problem of loss of gear sense due to long-term use and wear. At the same time, since the ball is omitted, the telescopic screw has a larger stroke, or the overall height dimension is shortened.

[0022] Reference Figure 1 to Figure 2 The trajectory adjustment tower of the present embodiment includes an adjustment tower base 10, an upper gear ring 20, an adjustment dial 30, a telescopic screw 40, a lower gear ring 50 and an elastic element 60. The trajectory adjustment tower uses the upper gear ring 20, the lower gear ring 50 and the elastic element 60 to replace the original spring, the ball and the outer ring gear disk structure, effectively solving the problem of loss of gear position due to long-term use and wear. At the same time, since the ball is omitted, the telescopic screw has a larger stroke, or the overall height dimension is shortened.

[0023] The adjustment tower 10 is cylindrical and is used to accommodate the adjustment dial 30 and the telescopic screw 40. The adjustment tower 10 is installed on the body of the sight. Figure 2 As shown, an external thread is arranged on the outer side of the adjustment tower seat 10, and the adjustment tower seat 10 can be screwed onto the sight through the external thread.

[0024] The upper gear ring 20 is fixed on the body of the scope. In addition, the upper gear ring 20 is located above the adjustment tower 10. When the adjustment dial 30 rotates in the adjustment tower 10, the upper gear ring 20 is fixed, so as to interact with the lower gear ring 50. The lower end of the upper gear ring 20 has a plurality of first teeth 21. The plurality of first teeth 21 are evenly distributed on the lower end of the upper gear ring 20.

[0025] The adjusting turntable 30 is rotatably arranged in the adjusting tower seat 10, and the upper end of the adjusting turntable 30 passes through the upper gear ring 20. The adjusting turntable 30 passes through the upper gear ring 20 to facilitate the rotation of the adjusting turntable 30.

[0026] The telescopic screw 40 is screwed on the lower end of the adjustment tower 10. The telescopic screw 40 is movably connected to the lower end of the adjustment dial 30, and the telescopic screw 40 can move up and down relative to the adjustment dial 30. When the adjustment dial 30 rotates, the telescopic screw 40 is driven to rotate. Since the telescopic screw 40 can move up and down relative to the adjustment dial 30, the telescopic screw 40 can move upward or downward, thereby completing the adjustment.

[0027] The lower gear ring 50 is movably sleeved on the outer side of the adjusting dial 30. The lower gear ring 50 is relatively fixed with the adjusting dial 30 in the horizontal direction through the limiting structure, that is, when the adjusting dial 30 rotates, the lower gear ring 50 rotates accordingly, but the lower gear ring 50 can still move along the height direction of the adjusting dial 30. The upper end of the lower gear ring 50 has a plurality of second teeth 51. The plurality of second teeth 51 are evenly distributed on the upper end of the lower gear ring 50. The second teeth 51 can mesh with the first teeth 21.

[0028] The elastic element 60 is disposed at the side end of the adjusting dial 30 and located at the lower end of the lower gear ring 50 . The elastic element 60 abuts against the lower gear ring 50 , so that the lower gear ring 50 is meshed with the upper gear ring 20 .

[0029] When the adjusting dial 30 rotates, the lower gear ring 50 is driven to rotate. The lower gear ring 50 meshes with the upper gear ring 20 under the action of the elastic element 60, so that the rotation has a gear sense. In addition, the structure of replacing the original spring, pin and outer ring gear disk effectively solves the problem of losing the gear sense due to long-term use and wear. At the same time, since the pin is omitted, the telescopic screw has a larger stroke, or the overall height dimension is shortened.

[0030] According to a trajectory adjustment tower of one embodiment of the present invention, the plurality of first teeth 21 all extend in the radial direction of the upper gear ring 20 , and the plurality of second teeth 51 all extend in the radial direction of the lower gear ring 50 .

[0031] According to a trajectory adjustment tower of one embodiment of the present invention, a limit slot 31 is provided at the lower end of the adjustment dial 30, and a limit block 41 is provided at the upper end of the telescopic screw 40. Figure 1The two ends of the limit block 41 and the two ends of the limit slot 31 abut against each other, so that when the adjusting dial 30 rotates, the telescopic screw 40 rotates accordingly. At the same time, the limit block 41 is movably arranged in the limit slot 31, and the telescopic screw 40 can move along the limit slot 31.

[0032] According to a trajectory adjustment tower of one embodiment of the present invention, in this embodiment, the limiting structure includes an outer hexagonal portion 32 and an inner hexagonal portion 52. The outer hexagonal portion 32 is arranged on the outside of the adjustment dial 30. The inner hexagonal portion 52 is arranged on the inside of the lower gear ring 50, and the inner hexagonal portion 52 fits with the outer hexagonal portion 32, so that when the adjustment dial 30 rotates, the lower gear ring 50 rotates accordingly.

[0033] Of course, the hexagonal shape of the outer hexagonal portion 32 and the inner hexagonal portion 52 is only one embodiment. In some embodiments, they are respectively an outer triangular portion and an inner triangular portion, or an outer elliptical portion and an inner elliptical portion, etc. That is, any non-circular shape can be used as long as the lower gear ring 50 and the adjusting dial 30 are relatively fixed in the horizontal direction.

[0034] According to one embodiment of the present invention, a trajectory adjustment tower is provided. Figure 2 In this embodiment, the elastic element 60 is a corrugated spring. Of course, in some embodiments, the elastic element 60 can also be a spring, which is sleeved on the outside of the adjusting dial 30 and abuts against the lower end of the lower gear ring 50.

[0035] According to a trajectory adjustment tower of one embodiment of the present invention, a spring support platform 33 is provided at the side end of the adjustment turntable 30, and the elastic element 60 is provided on the spring support platform 33. In this embodiment, the spring support platform 33 is annular. In other embodiments, the spring support platform 33 can also be evenly distributed protrusions. Of course, there are other embodiments, as long as the elastic element 60 can be supported.

[0036] According to a trajectory adjustment tower of one embodiment of the present invention, a rotation slot 34 for easy rotation is provided on the upper end of the adjustment dial 30. In this embodiment, the rotation slot 34 is a straight slot.

[0037] The adjustment dial 30 of the trajectory adjustment tower rotates, driving the telescopic screw 40 to rotate. Since the telescopic screw 40 can move up and down relative to the adjustment dial 30, the telescopic screw 40 can move upward or downward, thereby completing the adjustment and satisfying the basic function. At the same time, when the adjustment dial 30 rotates, it drives the lower gear ring 50 to rotate. The lower gear ring 50 engages with the upper gear ring 20 under the abutment of the elastic element 60, so that the rotation has a gear sense, replacing the original spring, ball and outer ring gear structure, and effectively solving the problem of loss of gear sense due to long-term use and wear. At the same time, since the ball is omitted, the telescopic screw has a larger stroke, or the overall height dimension is shortened.

[0038] In addition, a sight in this embodiment includes the above-mentioned ballistic adjustment tower. The sight uses the ballistic adjustment tower to replace the original spring, ball and outer ring gear structure, effectively solving the problem of loss of gear sense due to long-term use and wear. At the same time, since the ball is omitted, the telescopic screw has a larger stroke, or the overall height dimension is shortened.

[0039] The above embodiments are further explanations of the above contents of the present invention, but it should not be understood that the scope of the above subject matter of the present invention is limited to the above embodiments. All technologies realized based on the above contents belong to the scope of the present invention.
