Description

The optical equipment adapter

The utility model relates to a kind of being sleeved on the microscopical eye lens, and is connected the optical equipment adapter of various photographic goods.

At present, general when doing biological, medical research or criminal evaluation, the trickle part that can't check by microscopic examination naked eyes institute usually, but only check by naked eyes, do not note, then lose the purpose of observation, and can't be in order to explanation; Noted down and only can sketch in the past, so comparatively trouble inconvenience by Freehandhand-drawing.

Thereby have and on microscope, add one the 3rd, and by the 3rd connection camera, digital still camera or video camera etc., so can when observing, note down synchronously, and can note down more realistically with camera, digital still camera or video camera; But generally having the 3rd can it be expensive for the microscope of installing camera, digital still camera or video camera etc., non-general student or amateurish personage can bear, so as previously mentioned, the microscope of general no third eye then is inconvenient to do photorecording, thereby causes research and separate the trouble of saying and inconvenience.Moreover, when academic exchange, owing to can't learn the other side's microscopic examination equipment, therefore, if when academic exchange, will obtain individual's observed and recorded, then quite trouble inconvenience.The microscope of general no third eye can't use photographic goods such as camera, digital still camera or video camera to note down, and the microscope with the 3rd then costs an arm and a leg, and non-general student or amateurish personage can bear.

Fundamental purpose of the present utility model is to overcome the prior art deficiency, provides a kind of and uses various photographic goods to make the adapter of photorecording on the microscope of no third eye.

For this reason, the utility model provides a kind of optical equipment adapter, be equipped with a lens barrel in the one switching cylindrical shell, described lens barrel can replace microscopical eye lens and sleeve on microscopical eye lens position, be provided with location parts in this switching cylindrical shell below side again, be fixed on the microscopical eye lens position by this positioning element cylindrical shell of will transferring; The described switching cylindrical shell top adapter ring that is threaded is provided with a connecting portion that can connect various photographic goods in described adapter ring upper end.

In the utility model, described connecting portion is a screw thread.

In the utility model, described positioning element is a screw.

In the utility model, the middle section position of described lens barrel is provided with pin thread, and by this pin thread sleeve that is threaded, this lens barrel is inserted on the microscopical eye lens by sleeve.

In the utility model, described adapter ring is a long tubular.

In the utility model, described adapter ring is a flat ring-type.

In the utility model, described adapter ring is a ware shape, and has the pin thread of a small-bore digital still camera that is spirally connected at its top.

In the utility model, described adapter ring is a ware shape, and has the pin thread of a small-bore video camera that is spirally connected at its top.

In the utility model, described adapter ring is a tubular, is equiped with the snap ring that can rotate arbitrarily and can be connected camera in its top.

Characteristics of the present utility model and effect are: the optical equipment adapter can be sleeved on the eye lens of optical equipments such as microscope, further be connected various photographic goods by this adapter, thereby must on the microscope of no third eye, use various photographic goods etc. to make photorecording, equipment utilization factor height, convenient, flexible.

In conjunction with the accompanying drawings the utility model is described in detail as follows:

At first, see also Fig. 1 and Fig. 2, the utility model is mainly by being equipped with a lens barrel 2 in the switching cylindrical shell 1, this lens barrel 2 must be replaced the eye lens 31 of microscope 3, and sleeve is in eye lens 31 positions of microscope 3, be provided with a location screw 11 in this switching cylindrical shell 1 below side again, and be fixed on eye lens 31 positions of microscope 3 by this set screw nail 11 cylindrical shell 1 of will transferring, and this switching cylindrical shell 1 top adapter ring 4 that is threaded, have a pin thread 41 in these adapter ring 4 tops, and be connected various photographic goods 5 by the pin thread on this adapter ring 4 41.

According to above-mentioned structure, lens barrel on the eye lens 31 of microscope 3 must be taken off (not expression in graphic), and on the eye lens that directly are inserted into microscope 3 31 with lens barrel of the present utility model, and be fixed on the eye lens 31 by position set screw nail 11 of side below switching cylindrical shell 1, then with digital still camera, camera, the camera lens of photographic goods 5 such as numerical digit video camera or video camera is screwed onto on the pin thread 41 of adapter ring 4 of switching cylindrical shell 1, so can on the microscope 3 of general no third eye, use digital still camera, camera, photographic goods 5 such as numerical digit video camera or video camera, and can make photorecording by above-mentioned various photographic goods 5.

Moreover, this lens barrel middle section position be provided with pin thread 21, by this pin thread 21 sleeve 6 that is threaded, this lens barrel is inserted on the eye lens 31 of microscope 3 of another kind of dimensions, as shown in Figure 3 by sleeve 6.

Again, the eye lens 31 of general microscope 3 if eye lens 31 caliber sizes of this microscope 3 are φ 23, then can directly use above-mentioned lens barrel 2, as shown in Figures 1 and 2 in respect of 30 two kinds of φ 23 and φ; If the caliber size of the eye lens 31 of microscope 3 is φ 30, the sleeve 6 that then can below lens barrel, be spirally connected, make its be installed in 30～eye lens 31 on, as shown in Figure 3.
