First spread groove and second spread groove respectively with be connected bulge loop threaded connection, first spread groove and second spread groove are equipped with the internal thread respectively (concrete screw thread is not drawn), connect the bulge loop upper and lower wall be equipped with the external screw thread that the internal thread matches (concrete screw thread is not drawn), first linking frame and second linking frame like this dismantle the connection through the screw thread, so whole battery of lens is when vibrations or removal, lens b and lens an difficult separation, also the difficult separation between the lens b.
Further, as shown in fig. 7: first connection frame outer lane is connected with connector 22 for be connected with the bracing piece of lens formation of image research appearance, and the connector cover is on the bracing piece, both joints or threaded connection, so makes the utility model discloses it is convenient to be connected with lens formation of image research appearance.
The water convex lens is analyzed in detail, because the water is filled in the water lens, the two films of the water lens are gradually raised from top to bottom, and the two films of the water lens are not raised like two side walls of the convex lens when being pushed outwards due to the gradually increased pressure of the liquid from top to bottom, so that the convex lens is formed as shown in figure 4, and the most raised part of the projection is as the part indicated by the arrow in fig. 4 (not the thickest part in the middle of the convex lens), the more water is filled in the water lens, the more the part indicated by the arrow in fig. 4 is raised, namely, the water lens is thin at the top and thick at the bottom, and is not thin at the periphery of the middle part of the convex lens, so that the water lens is used for collecting light, compared with the converging effect of the convex lens, the difference is far, characters appearing on the light screen are not as clear as the real convex lens, light on the light screen is not bright enough easily, and the method is used for researching the lens not very well. In the embodiment, a plurality of lenses b and a lens a form a true convex lens with thick middle and thin periphery, which can achieve the effect of the convex lens and is better than the water lens.
Example 2
Compared with embodiment 1, the present embodiment is composed of concave lenses, so that the characteristics of concave lenses with different curvatures can be studied. Specifically, the method comprises the following steps: the lens a is a concave lens, the first wall attached to the lens a is a convex wall, the first wall between every two adjacent lenses b is a convex wall, and the second wall is a concave wall; the second wall of the outermost lens b is a concave wall; the curvature radiuses of all the second walls on the same side of the lens a become larger in sequence from the lens a to the direction far away from the lens a; all the lenses a and b constitute a lens with gradually increasing thickness from the middle to the surrounding. Thus, the present embodiment can be used to study not only the characteristics of the concave lens, but also how to deal with hyperopia, such as glasses with concave lenses.
Example 3
The difference between this embodiment and embodiments 1 and 2 is that the first connection frame and the second connection frame are connected in different ways, specifically as follows: permanent magnet sheets a are bonded on the bottom walls of the first connecting groove and the second connecting groove, permanent magnet sheets b which attract the permanent magnet sheets a are bonded on the end portions of the connecting convex rings, and the attraction force between the permanent magnet sheets a and the permanent magnet sheets b is 1-2N. Therefore, the first connecting frame and the second connecting frame are connected by the permanent magnetic sheets which are mutually attracted, the connecting frame does not need to be screwed like threads, so that the connection and the separation are more convenient, and the whole lens assembly is not easy to separate when moving or vibrating due to attraction force existing between the permanent magnetic sheets.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
