The utility model aims to overcome the problems, and provides an astronomical telescope focusing seat, which is provided with a tightening knob, wherein the tightening knob is reasonable in setting position and can stabilize the locking focal length position.
In order to achieve the above purpose, we provide an astronomical telescope focusing seat, which comprises a seat body and a focusing shaft movably connected with the seat body, wherein a positioning rack is arranged on the focusing shaft, a positioning hand wheel meshed with the positioning rack is arranged on the seat body, the positioning hand wheel rotates to drive the focusing shaft to move back and forth relative to the seat body, a tightening knob is arranged on the seat body, a stud in threaded connection with the seat body is arranged on the tightening knob, and the end of the stud is abutted to or separated from the positioning rack by rotating the tightening knob.
In one or more embodiments, the end of the stud is a plastic end.
In one or more embodiments, the surface of the tightening knob and the surface of the positioning hand wheel are both provided with anti-slip structures.
In one or more embodiments, the positioning rack and the focusing shaft are integrally formed with an aluminum alloy structure.
In one or more embodiments, the focusing shaft is installed in a cylinder cavity of the base, and a plurality of positioning parts contacted with the surface of the focusing shaft are distributed on the cavity wall of the cylinder cavity.
In one or more embodiments, the positioning portion is integrally formed with the barrel cavity.
Compared with the background technology, the utility model has the following technical effects: this focusing seat adopts and tightens up knob locking focus to tighten up knob direct lock and position the rack, with behind the rack lock, the focusing axle is difficult for appearing shifting under the influence of external force, ensures that the focus remains stable, and compared current direct lock adjusts the teaching axle itself, stability after the focus locking is better.
Drawings
FIG. 1 is a schematic view of a focusing seat according to an embodiment of the present utility model;
fig. 2 is a schematic view of the structure of fig. 1 at another angle.
Detailed Description
The present utility model will be further described in detail with reference to the following examples and drawings for the purpose of enhancing the understanding of the present utility model, which examples are provided for the purpose of illustrating the present utility model only and are not to be construed as limiting the scope of the present utility model.
Referring to fig. 1-2, the utility model provides an astronomical telescope focusing seat, which comprises a seat body 1 and a focusing shaft 2 movably connected with the seat body 1, wherein a positioning rack 3 is arranged on the focusing shaft 2, the positioning rack 3 and the focusing shaft 2 are of an integrally formed aluminum alloy structure, the structural connection tightness of the positioning rack 3 and the focusing shaft 2 is ensured, compared with the welding of the positioning rack 3 on the focusing shaft 2, the precision is more accurate and the stability is better, the seat body 1 is provided with a positioning hand wheel 4 meshed with the positioning rack 3, the positioning hand wheel 4 rotates to drive the focusing shaft 2 to move forwards and backwards relative to the seat body 1, the positioning hand wheel 4 comprises two rotating wheels and a rotating shaft for connecting the two rotating wheels, the rotating shaft is provided with a gear (not shown in the figure) meshed with the positioning rack 3, the rotating shaft is driven to rotate by rotating one rotating the rotating wheel, the positioning rack 2 is driven to move, the seat body 1 is provided with a tightening knob 5, and the tightening knob 5 is provided with a stud 6 in threaded connection with the seat body 1, and the end of the tightening stud 6 is abutted against the positioning stud 3 or separated from the rotating knob 5.
When in actual use, a user rotates the positioning hand wheel 4 to enable the focus adjusting shaft 2 to move forwards and backwards, when the focus adjusting shaft is moved to a proper position, the stud 6 is abutted with the positioning rack 3 by tightening the tightening knob 5, so that the positioning rack 3 is locked, and the positioning hand wheel 4 is also in a locking state; after the stud 6 is separated from the positioning rack 3 by unscrewing the tightening knob 5, the user can adjust the focal length again through the positioning hand wheel 4.
The end of the stud 6 is a plastic end, and the plastic end has certain softness, compared with the stud 6 made of hard metal, the extrusion of the stud 6 to the positioning rack 3 can be reduced, and the abrasion or deformation of the positioning rack 3 can be reduced.
The surface of tightening knob 5 and the surface of positioning hand wheel 4 all are equipped with anti-skidding structure, and anti-skidding structure comprises many recesses, and anti-skidding structure can increase frictional force, makes the user rotate tightening knob 5 and positioning hand wheel 4 more easily.
The focusing shaft 2 is arranged in a cylinder cavity 11 of the base body 1, the cylinder cavity 11 and the base body 1 are of an integrally formed injection molding structure, in order to ensure that the focusing shaft 2 and the cylinder cavity 11 are coaxial, a plurality of positioning parts 7 which are in surface contact with the focusing shaft 2 are distributed on the cavity wall of the cylinder cavity 11, the positioning parts 7 can ensure that the focusing shaft 2 keeps stability when moving forwards and backwards, shaking cannot occur, the positioning parts 7 and the cylinder cavity 11 are of an integrally formed structure, and the contact surfaces of the positioning parts 7 are arc-shaped.
