Abstract
The utility model provides a spiral sleeve eyepiece adjusting apparatus. The spiral sleeve eyepiece adjusting apparatus comprises an eyepiece sleeve and an outer sleeve. A diaphragm cylinder is tightly fastened in the eyepiece sleeve. One end of the eyepiece sleeve is equipped with protruding external thread. The outer sleeve is a hollow cylinder. One end of the hollow cylinder is equipped with protruding internal thread matched with the external thread of the eyepiece sleeve. The spiral sleeve eyepiece adjusting apparatus has beneficial effects that a spiral locking structure is designed between the eyepiece sleeve and the outer sleeve of a three-dimensional endoscope, that the outer sleeve can be adjusted to be spirally moved forwardly or backwardly, and that an adjusting purpose can be achieved just by rotating the outer sleeve. The eyepiece may satisfy an adjusting requirement within the shortest time. The eyepiece can be adjusted fast, easily, and accurately and can be fixed reliably.
Description
Technical field
The utility model relates to a kind of stereo endoscope optical path adjustment device, especially relates to a kind of screw sheel eyepiece adjusting gear.
Background technology
The adjustment of the eyepiece stalk in traditional endoscope is generally at circumferencial direction, with jackscrew, to be fixed after supporting by insertion.Such structure is in the middle of stereo endoscope, because be that two light paths affect each other, spatially restricted again, adjustment effect in this way bad, regulate the speed also very slow.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, safe and reliable screw sheel eyepiece adjusting gear.
The technical solution of the utility model is: a kind of screw sheel eyepiece adjusting gear, comprise eyepiece stalk and mirror overcoat, light hurdle cylinder is fastened in described eyepiece stalk, one end of described eyepiece stalk is provided with outstanding external thread, described mirror overcoat is hollow cylinder, its one end is provided with outstanding internal thread, mates with the external thread of described eyepiece stalk.
Advantage and the good effect that the utlity model has are:
We are designed to the structure of spiral locking between stereo endoscope eyepiece stalk and its overcoat, and front and back facilitate adjustable spiral to advance and the spiral mirror overcoat retreating, and only need to rotate mirror overcoat, just can reach our adjustment object.Make eyepiece can reach with minimum space adjustment requirement, fast, easily and accurately, adjust respectively, and reliably fixing.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present utility model;
Fig. 2 is the structural representation of eyepiece stalk in the utility model.
In figure:
1, eyepiece stalk 2, mirror overcoat
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model comprises eyepiece stalk 1 and mirror overcoat 2, light hurdle cylinder is fastened in described eyepiece stalk 1, one end of described eyepiece stalk 1 is provided with outstanding external thread, described mirror overcoat 2 is hollow cylinder, its one end is provided with outstanding internal thread, mates with the external thread of described eyepiece stalk 1.
During use, we are designed to the structure of spiral locking between stereo endoscope eyepiece stalk 1 and its mirror overcoat 2, and front and back facilitate adjustable spiral to advance and the spiral mirror overcoat 2 retreating, and only need to rotate mirror overcoat 2, just can reach our adjustment object.Make eyepiece can reach with the shortest time adjustment requirement, fast, easily and accurately, adjust respectively, and reliably fixing.
Above embodiment has been described in detail the utility model, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
