Description
Technical field
The present invention relates to a kind of focusing systems of endoscope, belong to endoscope structure design field.
Background technology
In the therapeutic process to certain diseases, need to observe patient's body correlation internal organs with endoscope, and lead to
It crosses photographic device and image taking is carried out to patient's body internal organs, while image being sent to external visual device.In existing
Sight glass does not all have focusing system mostly, cannot realize moving forward and backward for camera lens by adjusting the focal length of camera lens in practical applications
And the image of cleaning is obtained, and existing a small number of endoscopes with focusing system are when in use, due to the structure of focusing system
Not very rationally, therefore the adjusting of focal length operation is also more inconvenient, and user experience effect is poor.
Invention content
In this regard, the present invention is intended to provide a kind of focusing system of the convenient endoscope of focus operations.
Realizing the technical solution of the object of the invention is：
A kind of focusing system of endoscope, including outer sleeve, inner sleeve, lens unit, camera unit, bevel gear, adjusting
Idler wheel, connecting rod and bearing, the inner sleeve are arranged in the outer sleeve and are connected by bearing, and the camera unit is fixed
In the rear end of the inner sleeve, the lens unit, which can axially move, to be arranged in the inner sleeve, the lens unit packet
Lens barrel and the lens group in the lens barrel are included, there is the bar shaped along its axially extending setting on the inner sleeve side wall
Hole is provided with spiral yarn shaped guiding groove on the inner wall of the outer sleeve, and the lens barrel external stability has cylinder, the cylinder
Outer end stretches into across the strip-shaped hole in the guiding groove, forms and is evenly distributed in the back end circumference of the outer sleeve
Engaging tooth, the tooth on the bevel gear are meshed with the engaging tooth, and the adjusting idler wheel passes through the connecting rod and the cone
Gear is fixedly and coaxially connected.
In above-mentioned technical proposal, screw hole is formed on the outer wall of the lens barrel, one end of the cylinder, which is equipped with, to be threadedly coupled
Portion, the threaded joints are spirally connected with the screw hole.
In above-mentioned technical proposal, regulating tank is formed on one end end face far from the threaded joints on the cylinder,
The regulating tank is linear type slot or cross bath.
The present invention has the effect of positive：Using the structure in the present invention, when focusing, the adjusting idler wheel is rotated
And then rotated with dynamic bevel gear, due to driving outer sleeve to turn when the matching relationship bevel gear of the upper tooth of bevel gear and engaging tooth rotates
It is dynamic, outer sleeve when rotating the cylinder occurs to relatively move in guiding groove to drive lens unit edge in inner sleeve
It moves axially back and forth, to change the distance between the lens unit and camera unit, achievees the purpose that focus, thus
It can be seen that as long as manual rotation adjusts idler wheel when focusing, focus operations are convenient, improve user experience；With the tune
The endoscope of burnt system can focus, to obtain relatively sharp image, to have very in actual use as needed
Good using effect.

Specific implementation mode
The concrete structure in the present invention is done with explanation with reference to the accompanying drawings of the specification：
A kind of focusing system of endoscope, structure is as shown in Figure 1 to Figure 3, including outer sleeve 1, inner sleeve 2, lens list
Member 3, bevel gear 9, adjusts idler wheel 5, connecting rod 6 and bearing 7 at camera unit 4, and the inner sleeve 2 is arranged in the outer sleeve 1
And connected by bearing 7, the camera unit 4 is fixed on the rear end of the inner sleeve 2, and the lens unit 3 can move in an axial direction
Dynamic to be arranged in the inner sleeve 2, the lens unit 3 includes lens barrel 31 and the lens group 32 in the lens barrel 31,
There is the strip-shaped hole 21 along its axially extending setting on 2 side wall of the inner sleeve, spiral is provided on the inner wall of the outer sleeve 1
Linear guiding groove 11,31 external stability of the lens barrel have cylinder 8, the outer end of the cylinder 8 to be stretched into across the strip-shaped hole 21
In the guiding groove 11, the engaging tooth 12 being evenly distributed, the bevel gear are formed in the back end circumference of the outer sleeve 1
Tooth on 9 is meshed with the engaging tooth 12, and the adjusting idler wheel 5 is coaxial fixed with the bevel gear 9 by the connecting rod 6
Connection.Camera unit in the present embodiment uses existing camera unit, and structure belongs to the prior art, in the present embodiment
It will not go into details.Using the structure in the present embodiment, when focusing, rotates the adjusting idler wheel 5 and then revolved with dynamic bevel gear 9
Turn, due to driving outer sleeve 1 to rotate when the matching relationship bevel gear 9 of tooth and engaging tooth 12 on bevel gear 9 rotates, 1 turn of outer sleeve
When dynamic the cylinder 8 relative movement occurs in guiding groove 11 to drive the lens unit 3 in inner sleeve 2 in an axial direction before
After move, to change the distance between the lens unit 3 and camera unit 4, achieve the purpose that focus, it can be seen that
As long as manual rotation adjusts idler wheel 5 when focusing, focus operations are convenient, have good using effect；With this
The endoscope of focusing system can focus as needed in actual use to obtain relatively sharp image.
