Detailed description of the invention

As depicted in figs. 1 and 2, be toy projector of the present utility model.

This toy projector has housing, in housing, is provided with convex lens 103, is with figuratum film 105, electric light source 108 along optical axis direction.Preferably, housing axis and optical axis dead in line.

Housing is made up of the first assembly 201 and the second assembly, and the first assembly can rotate relative to the second assembly.The first assembly has upper and lower two end faces 201.1 and 201.2 vertical with optical axis.The first assembly upper surface 201.1 is provided with projection hole.The first assembly 201 inner chambers are nested with a tubular cutting ferrule 101, and tubular cutting ferrule 101 peripheries are provided with projection, extend into the groove of the first assembly 201 inwalls, thereby prevent that tubular cutting ferrule 101 and the first assembly from relatively rotating.Further, between tubular cutting ferrule 101 and the first assembly 201, can also bind and fix with binders such as glue.Tubular cutting ferrule 101 lower ends are provided with shirt rim 101.1, between this shirt rim 101.1 and the lower surface 201.2 of the first assembly 201, form groove, can be connected in the upper surface of housing the second assembly, thereby make the first assembly 201 in the time that the second assembly rotates, relative axial position between the first assembly and the second assembly remains unchanged, and the first assembly is can relative the second assembly not overhanging or inside contract.

The second assembly of housing is made up of at least two bodies, preferably, adopts four bodies 202,203,204,205 to enclose the structure that encloses of formation upper opening.The housing enclosing can be for different shapes, circular or square or irregularly shaped all can, in this example, adopted ellipse.The second assembly being enclosed by four bodies has level and smooth upper surface, and it can smoothly contact with the lower surface 201.2 of the first assembly.Body inwall is provided with many places postive stop baffle and groove, for example, for limiting the groove 203.1 of tubular cutting ferrule 101 shirt rims.

Electric light source 108 is fixed in lamp socket 107, is with figuratum film 105 to be fixed in film seat 106.In this example, lamp socket 107 is socketed on film seat 106, and both form detachably or unremovably and are fixedly connected with.Lamp socket 107 has been avoided relatively rotating between the two with film seat 106 by the bolt shape structure 107.1 that protrudes from lamp socket 107 peripheries, and meanwhile, film 105 is also configured as the bottom surface of same shape, and film 105 can stably be placed in film seat 106.Lamp socket 107 and film seat 106 after assembling are fixed on body, for example, limit its moving axially and rotating in a circumferential direction with respect to body by body groove 203.2.Further, also can adopt adhesive in addition bonding or fix with the form such as ultrasonic.

Convex lens 103 are fixed on eyeglass seat 102, and by the eyeglass gland 104 of a tubular, convex lens 103 are fixed in the forefront of eyeglass seat 102.Eyeglass seat 102 outer walls are provided with external screw thread, and tubular cutting ferrule 101 inwalls are provided with internal thread, and eyeglass seat forms and is threaded between the two with tubular cutting ferrule.The inwall of eyeglass seat 102 and film seat 106 form pivot bush unit.The outer wall of eyeglass seat 102 is also provided with dentalation 102.1, is connected in the projection of body inwall, thereby restriction eyeglass seat 102 rotates in a circumferential direction.In the time that body the first assembly 201 rotates with respect to body the second assembly, because the dentalation of eyeglass seat 102 is subject to the restriction of body inwall projection, therefore eyeglass seat 102 can not be followed the first assembly rotation, change the motion that rotates in a circumferential direction into rectilinear motion along axis and be threaded connection, therefore, eyeglass seat can be between tubular cutting ferrule 101 and film seat 106 rectilinear motion.This rectilinear motion has changed the axial distance between convex lens 103 and film 105, i.e. object distance has also changed image distance.Can change the distance between convex lens 103 and film by rotating the first assembly, may be adjusted to position and the definition of picture.

In this example, be provided with tubular cutting ferrule at the first assembly inner chamber, thereby it is threaded with eyeglass seat, mode as an alternative, unites two into one tubular cutting ferrule and housing the first assembly, makes it to be threaded and to be certainly also fine with eyeglass seat.

Above-mentioned film seat and lamp socket also can adopt and be different from version shown in the drawings, and for example lamp socket outside, film seat is fixed by socket form interiorly, and the inwall of eyeglass seat 102 is with lamp socket but not film seat forms pivot bush unit like this.In a word, its fixed form is the alternative structure that those skilled in the art easily expect.

Certainly, microscope base also can be set to the mode of fixing Nonadjustable focusing, only needs fixed mirror bar at body.

Preferably, described electric light source is provided by light emitting diode.Article two, circuit lead stretches out and exposes to outside lamp socket from electric light source, and wherein a lead-in wire 108.1 keeps in touch and is connected with the wire 110 with resistance, and wire 110 keeps in touch with first utmost point 109.1 of battery 109.The effect of wire 110 is the resistance by increasing, and reduces the power of LED, thereby reduces the brightness of LED, to reach the effect of child protection eyesight.Wire 110 can be welded and fixed with lead-in wire 108.1, can certainly not be welded and fixed.Certainly, as a kind of simplified design, also strip resistance not of wire 110, the setting of even omitting wire 110.

Wherein a body is provided with perforation, for example body 203, and button 112 is exposed to outside housing through this perforation from housing inner chamber.The back-moving spring 111 of being manufactured by conductive material is arranged at button 112 and is positioned at a side of housing inner chamber, and acts on button 112.Back-moving spring 111 has two elongation ends, and wherein keep in touch with second utmost point 109.2 of battery one end 111.1, and this elongation end presses on inner walls.The other end 111.2 of back-moving spring keeps non-contacting gap with another lead-in wire 108.2 of electric light source, and this non-contacting gap is less than knob 112 and protrudes from the length outside housing.In the time that button 112 is subject to External Force Acting to be pressed in housing inner chamber, the other end 111.2 of back-moving spring comes in contact with another lead-in wire 108.2 of diode, thereby makes the electric loop conducting between battery and electric light source, and electric light source is luminous.In the time that external force disappears, knob 112 is reset to origin-location by back-moving spring, and the other end 111.2 of back-moving spring is returned to and keeps non-contacting gap with another lead-in wire 108.2 of diode, and circuit returns back to off-position.Because back-moving spring is manufactured by conductive material, therefore back-moving spring self is a part for circuit lead, can realize circuit turn-on by back-moving spring with battery with contacting of electric light source lead-in wire.Certainly, the utility model can also be realized by another way, for example, increase circuit lead, between back-moving spring and battery or between back-moving spring and electric light source lead-in wire, is increasing circuit lead; Can reduce again circuit lead, for example, reduce the setting of wire 110, make back-moving spring and electric light source lead-in wire that the mode being electrically connected directly occur.And in electrical contact described in this description comprised the direct electrical connection situation between two components, also comprises between component and refutes by other circuit lead the situation about being electrically connected that connects.

Preferably, battery 109 adopts button cell, can adopt many battery series connection.The baffle plate that battery 109 is arranged by inner walls is defined in housing battery flat.
