Description
Technical Field
The utility model relates to an optics telescope system especially relates to a knob institutional advancement that carries out focusing in the gun sight like optics sighting telescope.
Background
In the existing optical telescope system, such as the optical aiming lens, in order to realize the resolution of different distances, a focusing structure is generally arranged on a lens barrel, but in the focusing structure of the prior art, a sleeve with a lens or a lens group is generally directly rotated to generate movement along the optical axis direction, and if the telescope system with a large caliber generally adopts a structure that an objective lens moves back and forth and a field lens does not move, the focusing is inconvenient because the objective lens is adjusted. However, in some precise optical telescopic devices, such as an optical sighting lens for a firearm, the lens barrel is generally long, and it is very inconvenient to directly rotate the lens barrel.
However, the side focusing knob structure in the prior art cannot solve the problem that the influence on the optical axis of the lens, which is generated when the side knob rotates, can cause optical axis tremble and division wire center deviation in the adjusting process, and the adjusting structure affects the vertical and horizontal deviation of the optical axis, so that the normal adjusting action of a hand wheel is affected, and if the optical axis is adjusted firstly and then the focusing process can cause the adjusted optical axis to deviate.
In view of the above-mentioned drawbacks of the prior art, the applicant has developed and previously filed a patent application, whose basic structure is shown in fig. 1, and is a focusing handwheel structure of a gun sight, which is fixed on a lens barrel 110 and includes a knob outer cover 120 fixedly connected with a knob inner cover 130; a lower cover 140 fixed on the lens barrel 110 and adapted to the knob cover 120; the lower end surface of the knob inner cover 130 is eccentrically provided with a mounting concave hole 131, an elastic component 132 and a projecting column part 133 are sequentially mounted in the mounting concave hole 131, the lower end of the projecting column part 133 extends into the lens barrel 110, the lower end of the projecting column part 133 is a flat sliding chute 134, and the flat sliding chute 134 is matched with a transverse sliding block 112 arranged on an inner sleeve 111 of a bearing lens group in the lens barrel 110. Thus, when the knob outer cover 120 is rotated, the knob inner cover 130 is linked to rotate, and since the mounting concave hole 131 and the projection column part 133 therein are eccentrically arranged on the knob inner cover 130, the rotation of the knob inner cover 130 will cause the projection column part 133 to displace in the axial direction of the inner sleeve 111 and in the direction perpendicular to the axial direction; the projecting post 133 is slidably engaged with the lateral slider 112 in a direction perpendicular to the axial direction of the inner tube 111, so that displacement perpendicular to the axial direction is eliminated, and only displacement is provided in the axial direction of the inner tube, thereby moving the position of the lens in the inner tube and realizing a convenient and accurate focusing operation.
However, in the above structure, the projecting column part 133 and the transverse slider 112 can be adapted to each other only by the supporting of the elastic member 132, and in the actual gun sight use process, the projecting column part 133 and the transverse slider 112 may collide with each other, and the gun sight is vibrated in the movement, so that the projecting column part 133 and the transverse slider 112 are separated from each other by excessive vibration, and once the projecting column part and the transverse slider are separated, the inner sleeve is displaced back and forth and cannot be reset, and the whole gun sight cannot be used at all; in addition, the addition of the elastic member also increases the production cost, increases the difficulty of the assembly process, and thus increases the cost.
The prior art is therefore deficient and is subject to continued improvement and development.
