Abstract
The utility model relates to a focusing mechanism for an eye lens of a telescope, which comprises an eye lens barrel, an eye lens seat, a focusing mount and a male pin, wherein, an assembly structure formed by coaxially sheathing and fixedly connecting the eye lens barrel, the eye lens seat and the focusing mount on a lens body is adopted. Moreover, the lower part of the eye lens barrel forms a screw thread driving cooperation with the eye lens seat, and the upper part of the eye lens barrel forms a gear driving cooperation with the focusing mount so as to enable the manufacturing technique of telescope products to be simplified and to greatly reduce requirements for the machining precision and the assembly precision of parts and components. The utility model has the advantages of reduced production cost, reliable use, high durability, high focusing precision, etc.
Description
The utility model relates to telescope ocular focus adjustment mechanism.
Traditional telescope ocular focus adjustment mechanism is made up of eyepiece stalk, eyepiece mount, focusing mount and guide pin, guide pin is connected on the eyepiece stalk, and mill out the skewed slot that cooperates together on the focusing mount curved surface with guide pin, when focusing mount rotates, skewed slot drives guide pin and makes the front and back rectilinear motion, thereby eyepiece can elasticly be focused.Because guide pin, focusing mount form by metalwork machining, and both do accurate transmission and cooperate, and are therefore higher to the requirement on machining accuracy of guide pin and focusing mount.Its problem that directly causes is: 1. parts requirement on machining accuracy height, production cost height; 2. the qualification rate of parts is low, makes telescope overall acceptability rate also low; 3. process and assemble complexity, production efficiency is low.
The purpose of this utility model is the weak point that overcomes above-mentioned prior art, and the telescope ocular that a kind of process and assemble is simple, production cost is low, reliability is high focus control is provided.
The purpose of this utility model is achieved by the following technical solution: the telescope ocular focus control is made of eyepiece stalk, eyepiece mount, focusing mount, pin, eyepiece mount is fixed on the telescope mirror body, special feature is eyepiece stalk, eyepiece mount, focusing mount three coaxial package, and the bottom of eyepiece stalk forms the screw thread transmission with eyepiece mount and cooperates.The top of eyepiece stalk cooperates with the transmission of focusing mount formative gear.Further, eyepiece stalk is shaped to lower external thread, top outer rotor, the screw-internal thread fit of its external thread and eyepiece mount; Its outer rotor cooperates with the annular wheel on focusing mount top.Pin then is fixed on the eyepiece mount, and cooperates with arc guide barrel on the focusing mount.
Fig. 1 is a three-dimensional mounting or dismounting synoptic diagram of the present utility model;
Fig. 2 is an assembling synoptic diagram of the present utility model.
Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.
Referring to Fig. 1 and Fig. 2, present embodiment is made of eyepiece stalk 1, eyepiece mount 2, focusing mount 3 and 4 four members of pin, and their coaxial packages are assemblied on the telescope mirror body 5.Wherein eyepiece stalk 1 is divided into upper and lower two parts, and the bottom of eyepiece stalk 1 has four-head external thread 11, and top then forms outer rotor 12.2 of eyepiece mounts are fixed on the mirror body 5 by external thread, and the inwall of eyepiece mount 2 then has the four-head internal thread 21 that cooperates with the external thread 11 of eyepiece stalk 1.The inwall of focusing mount 3 is divided into up and down two parts equally, and its inwall bottom forms the gaps rotation with eyepiece mount 2 and cooperates, its upper inside wall then form annular wheel 31 reach around arc guide barrel 32, annular wheel 31 can mesh with the outer rotor 12 on eyepiece stalk 1 top.The arc guide barrel 32 that 4 of pins pass focusing mount 3 is fixed on the eyepiece mount 2.
Assembling process is such: at first eyepiece mount 2 is rotatably connected on the mirror body 5, again eyepiece stalk 1 is screwed in the eyepiece mount 2, focusing mount 3 is flush-mounted on the eyepiece mount 2 then, and make the annular wheel 31 of focusing mount 3 and the outer rotor 12 of eyepiece stalk 1 mesh, the arc guide barrel 32 that at last pin 4 is passed focusing mount 3 is fixed on the microscope base 2, finishes assembling.
The focusing process is such: clockwise direction is rotated focusing mount 3, the annular wheel 31 of focusing mount 3 drives outer rotor 12 and does the clockwise direction rotation, eyepiece stalk 1 turns clockwise, because eyepiece stalk 1 is threaded with eyepiece mount 2, and eyepiece mount 2 is fixed on the mirror body 5, so eyepiece stalk 1 reach zoom; Otherwise counterclockwise rotate focusing mount 3, move zoom behind the eyepiece stalk 1.And the scope of eyepiece stalk 1 zoom limits by the arc length degree of the arc guide barrel on the focusing mount 3 32, by pin 4 as spacing point.
In sum, the utlity model has obvious advantage:
1. each parts can be used the plastic pressure injection moulding, no matter from material, all big on the production technology Reduced greatly production cost;
2. each component coaxial suit makes assembling easily simple, has improved production efficiency;
3. the machining precision of parts and assembly precision require greatly to reduce, and product reliability improves a lot;
4. four-head screw thread focusing accuracy height uses reliable, durable.
