Abstract
The utility model relates to a concave-convex lens experiment device, and particularly relates to a concave-convex lens with variable focal length. The concave-convex lens is mainly composed of a lens, a handle and a supporting frame. The lens and the handle are connected via the supporting frame. The lens is an enclosed circular elastic film device which is internally filled with transparent glue system material. The lower end of the lens is connected with an elastic hydraulic zooming regulator. A communicating tube is arranged between the regulator and the film device. The transparent glue system material flows into the film device of the lens via the communicating tube. Advantages of the concave-convex lens are that the regulator is pressed, and the transparent glue system material flows into the film device of the lens via the communicating tube so that conversion between a concave mirror and a convex mirror is realized. Meanwhile, the amount of the transparent glue system material flowing into the film device of the lens can be adjusted according to requirements so that change of focal length of the concave-convex lens is realized.
Description
Technical field
The utility model relates to a kind of concave and convex lenses experimental provision device, specifically, relates to the variable concave and convex lenses of a kind of focal length.
Background technology
As everyone knows, concave mirror has amplification, claims again presbyopic glasses or condenser; Convex mirror has the effect of dwindling, and claims again near-sighted glasses or astigmatoscope, and the exclusive feature of concave mirror and convex mirror makes its range of application more next and extensive.And existing concave mirror or convex mirror are mostly independent design, function is comparatively single, and conventionally the focal length of concave mirror or convex mirror is changeless, the focal length of case change concave mirror or convex mirror to need other lens to cooperate, both inconvenient, also dumb.
Utility model content
The purpose of this utility model is to provide the variable concave and convex lenses of a kind of focal length, can change as required the focal length of concave and convex lenses, and can realize the mutual conversion between concave mirror and convex mirror.
The technical solution of the utility model is: the concave and convex lenses that a kind of focal length is variable, mainly by lens, handle and bracing frame, formed, lens are connected by bracing frame with handle, it is characterized in that: described lens are the round and elastic membrane unit of sealing, this membrane unit inside is filled with transparent adhesive tape prepared material, described lens lower end is connected with elastic hydraulic zoom regulator, between this regulator and membrane unit, be provided with communicating pipe, described transparent adhesive tape prepared material flows into the membrane unit of lens by this communicating pipe.
Preferably, the spherical device that described elastic hydraulic zoom regulator is hollow, presses this spherical device transparent adhesive tape prepared material and enters into membrane unit by communicating pipe, regulates the focal length of lens.
Preferably, described communicating pipe place is provided with the switch valve of controlling communicating pipe on off state.
Preferably, described handle is provided with the circular protrusion with anti-skidding effect.
The utility model beneficial effect is compared with prior art:
(1) lens of these concave and convex lenses are the round and elastic membrane unit of sealing, this membrane unit inside is filled with transparent adhesive tape prepared material, lens lower end is connected with elastic hydraulic zoom regulator, between this regulator and membrane unit, be provided with the communicating pipe of circulating liquid, press this regulator, transparent adhesive tape prepared material flows into the membrane unit of lens by this communicating pipe, realize the conversion between concave mirror and convex mirror, can regulate as required the amount of transparent adhesive tape prepared material in the membrane unit that flows into lens, realize the change to concave and convex lenses focal length simultaneously;
(2) locating to be provided with the switch valve of controlling communicating pipe on off state communicating pipe, when in the membrane unit that flows into lens, the amount of transparent adhesive tape prepared material is determined, by this switch valve, the liquid in membrane unit and elastic hydraulic zoom regulator is blocked, guarantee that now the focal length of concave and convex lenses is stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-lens, 2-handle, 3-bracing frame, 4-elastic hydraulic zoom regulator, 5-communicating pipe
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
Referring to Fig. 1, the concave and convex lenses that a kind of focal length is variable, mainly by lens 1, handle 2 and bracing frame 3, formed, lens 1 are connected by bracing frame 3 with handle 2, lens 1 are the round and elastic membrane unit of sealing, and this membrane unit inside is filled with flowable transparent adhesive tape prepared material, and lens 1 lower end is connected with elastic hydraulic zoom regulator 4, between this regulator 4 and membrane unit, be provided with communicating pipe 5, transparent adhesive tape prepared material flows into the membrane unit of lens 1 by this communicating pipe 5.
Elastic hydraulic zoom regulator 4 is positioned at the bottom of lens 1, spherical device for hollow, while pressing this spherical device, transparent adhesive tape prepared material in spherical device enters into membrane unit by communicating pipe 5, making to be filled with to the thickness of the transparent adhesive tape prepared material in membrane unit increases, and then regulates the focal length of lens 1.
Handle 2 is positioned at the bottom of bracing frame 3, and handle 2 is provided with the circular protrusion with anti-skidding effect.Communicating pipes 5, place was provided with the switch valve of controlling communicating pipes 5 on off state, when in the membrane unit that flows into lens, the amount of transparent adhesive tape prepared material is determined, by this switch valve, the liquid in membrane unit and elastic hydraulic zoom regulator is blocked, guarantee the now focal length stability of concave and convex lenses.
Claims (4)
1. concave and convex lenses that focal length is variable, mainly by lens, handle and bracing frame, formed, lens are connected by bracing frame with handle, it is characterized in that: described lens are the round and elastic membrane unit of sealing, this membrane unit inside is filled with transparent adhesive tape prepared material, described lens lower end is connected with elastic hydraulic zoom regulator, between this regulator and membrane unit, is provided with communicating pipe, and described transparent adhesive tape prepared material flows into the membrane unit of lens by this communicating pipe.
