Description

Teaching aid for tissue embryology

Technical Field

The utility model relates to the field of machinary, especially, relate to a teaching aid of tissue embryology.

Background

Histology and embryology are the methods for studying human body's fine structure, functional relationships and development. It often needs the structure of surveing of observation cell in teaching process, and in the course of giving a lesson, sometimes needs the student directly to observe the structure of cell under the microscope, can show the image of microscope on the display through the camera display sometimes. The existing connecting method of the camera and the microscope is usually through threaded connection or clamping connection. There are also two lenses arranged by using a light splitting structure. However, when the camera is screwed, the camera needs to be rotated for many circles, so that the camera is inconvenient to disassemble and assemble and the data wire is easy to curl. And adopt the mode of joint, adopt the elastic component centre gripping usually, because frictional force is too big in the dismouting in-process, wearing and tearing appear very easily, lead to the joint not hard up. With the light splitting structure, since light is split and reflected or refracted for multiple times, image distortion and blurring are likely to occur, and thus improvement is required.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a teaching aid for tissue embryology. The utility model discloses simple structure, convenient to use can realize the high-speed joint and the dismantlement of camera, and the camera is difficult for droing and wearing and tearing appear.

The purpose of the utility model is realized through the following technical scheme:

a tissue embryology teaching aid comprises a display screen and a microscope, wherein the display screen is electrically connected with a camera through a data line, L-shaped guide grooves which are symmetrically arranged are concavely formed on two sides of the top of an eyepiece of the microscope, a clamping groove is concavely formed at the tail end of the bottom of each L-shaped guide groove, the camera is connected with a sleeve, and clamping blocks corresponding to the L-shaped guide grooves and the clamping grooves are fixed on two sides of the inner wall of the sleeve; still slidable mounting has the throw-out collar in the sleeve, and the throw-out collar passes through elastic construction and is connected with the camera.

In a further improvement, the elastic structure is a spring.

In a further improvement, the microscope is connected with a plurality of objective lenses through converters.

In a further improvement, the outer diameter of a camera lens on the camera is smaller than the inner diameter of the push ring.

In a further improvement, the display screen is a liquid crystal display screen.

The beneficial effects of the utility model reside in that:

the utility model discloses simple structure, convenient to use can realize the high-speed joint and the dismantlement of camera, and the camera is difficult for droing and wearing and tearing appear.

The present invention is further explained by using the attached drawings, but the content in the attached drawings does not constitute any limitation to the present invention.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic cross-sectional view of the sleeve;

fig. 3 is a bottom view of the sleeve.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Example 1

The teaching aid for histology and embryology shown in fig. 1-3 comprises a display screen 1, a microscope 2, a data line 3, a camera 4, an ocular 5, an L-shaped guide groove 6, a clamping groove 7, a sleeve 8, a clamping block 9, a push ring 10, an elastic structure 11, a converter 12, an objective 13 and a camera 14.

The microscope comprises a display screen 1, a data line 3, a camera 4, a sleeve 8, clamping blocks 9 and a positioning device, wherein the display screen 1 is a liquid crystal display screen, the display screen 1 is electrically connected with the camera 4 through the data line 3, L-shaped guide grooves 6 which are symmetrically arranged are concavely formed in two sides of the top of an eyepiece 5 of the microscope 2, clamping grooves 7 are concavely formed in the tail ends of the bottoms of the L-shaped guide grooves 6, the camera 4 is connected with the sleeve 8, and the clamping blocks 9 corresponding to the L-shaped guide grooves 6 and the clamping grooves 7 are fixed on two sides of the inner wall of the sleeve 8; a push ring 10 is further slidably mounted in the sleeve 8, and the outer diameter of a camera lens 14 on the camera 4 is smaller than the inner diameter of the push ring 10. The push ring 10 is connected with the camera 4 through a spring.

The microscope 2 is connected to several objective lenses 13 via a converter 12.

The utility model discloses application method as follows:

when the field of vision of microscope is projected on the display screen, camera 4 is held by hand, so that clamping block 9 in sleeve 8 is aligned with L-shaped guide groove 6 and pressed down, in the pressing down process, objective lens can extrude push ring 10, the bottom end of L-shaped guide groove 6 is pressed and then rotated to the tail end of L-shaped guide groove 6, then the hand is loosened, the interior of camera 14 is bounced under the elasticity of spring, so that clamping block 9 is clamped into clamping groove 7, the fixation of the camera is completed, and then the camera takes a picture to be displayed on the display screen.

When needing the student to go up through microscope direct observation image to the podium, push down camera 4, then the gyration is extracted the camera again, dismantles and get off and accomplish the quick dismantlement of camera promptly.

Consequently the structure of this practicality does not set up the joint structure that needs interference fit, only needs rotatory less angle during the connection, and effectively prevented behind the joint that the rotation of camera leads to with pulling out to drop.

It should be finally noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
