Description
Technical field
The utility model relates to a kind of projection equipment, particularly relate to a kind of simple in structure, mainly as a kind of slide projector of children study and amusement.
Background technology
Existing slide projector is divided into automatically, manually, popular, and four kinds of slide projector toys.Common slide projector is easy to use, and structure often becomes increasingly complex, so that price is more expensive, therefore popularizes in the family than difficulty.And existing slide projector toy, general bulb power is less, brightness is very low; Only adopt the monolithic convex lens, even use low-grade glass lens, anamorphose is serious after causing showing.
Summary of the invention
The purpose of this utility model provides a kind of simple and practical, safe and reliable and slide projector with better image quality.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of slide projector, comprise a housing 1, be provided with light source in the housing 1, the relative light source of housing 1 one ends place is provided with a barrel 2, this barrel 2 is provided with a biconvex lens 3 at the end away from light source, is provided with on the housing 1 to be used to the slot placing lantern slide and parallel with biconvex lens 3 between barrel 2 and light source.
Be connected by screw thread 4 between described barrel 2 and the housing 1, make barrel 2 housing 1 rotation relatively, and regulate the distance between biconvex lens 3 and the slot.
Described screw thread 4 is a single thread.
Be arranged with two single convex lens 5 in parallel near the slot place between described slot and the light source.
Described light source is one to have the Halogen lamp LED of reflection shield.
Described Halogen lamp LED with reflection shield is fixed on the lamp socket 6, and this lamp socket 6 is provided with at least one group of heat radiator 7.
Described lamp socket light source rear is provided with radiator fan 8.
Described housing 1 is provided with at least one group of louvre 9.
The position that described louvre 9 is positioned on the housing heat radiator 7 relatively with or the position of relative radiator fan 8.
The position of relative louvre 9 is provided with the louver (-vre) sheet 10 that prevents that light from penetrating from louvre in the housing.
Owing to adopted above scheme, made the utility model possess following beneficial effect:
Slide projector volume of the present utility model is little, simple in structure, reliable operation, with low cost, image quality is good, having utilized as far as possible simple combination to realize good optical projection quality.
Between barrel and the housing single thread is set, can focuses easily, make focusing clear.
One group of set two single convex lens make image quality that good assurance arranged.
The Halogen lamp LED with reflection shield that is adopted has characteristics such as brightness height, light beam are concentrated, excellent colour temperature, the suitable housing of the present utility model of size, and because its operating voltage low (12v), thereby security performance is guaranteed.
The setting of heat radiator, radiator fan and louvre has solved the heat dissipation problem that adopts high-power bulb to draw, and has further guaranteed security and reliability that slide projector of the present utility model uses.
The setting of louver (-vre) sheet has on the one hand avoided veiling glare to project outside by louvre, makes again that on the other hand air can free flow, has guaranteed the efficient of heat radiation.
Description of drawings
Fig. 1 is dismantle a vertical view behind the upper casing of a kind of slide projector of the present utility model.
Fig. 2 is dismantle a side view behind the upper casing of a kind of slide projector of the present utility model.
Fig. 3 is the external form figure of a kind of slide projector of the present utility model.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
See Fig. 1,2,3.
The slide projector toy that a kind of children study and amusement are used comprises the housing 1 (comprise upper and lower shell, after upper and lower shell separates as shown in Figures 1 and 2) of lucky pig shape (as shown in Figure 3, wherein louvre does not draw).The face position of the lucky pig of housing 1 front end is provided with a barrel 2, links to each other by single thread 4 between barrel 2 and the housing 1.Barrel 2 be provided with a biconvex lens 3 foremost.
Be provided with low pressure (normally 12V) Halogen lamp LED that is fixed in the aluminum lamp socket 6, is with reflection shield in the housing 1.Be respectively arranged with two heat radiator 7 on the both sides of aluminum lamp socket 6, the rear of aluminum lamp socket 6 is provided with the interchange radiator fan 8 of a 12V.The position of relative heat radiator 7 and radiator fan 8 is respectively arranged with one group of louvre that is rectangle 9 (totally three groups) on the housing 1 of lucky pig, and is respectively arranged with the louver (-vre) sheet 10 of similar window shutter between louvre 9 and heat radiator 7 or radiator fan 8.
The optical glass lens of this slide projector also comprises one group of two single convex lens 5 except that the biconvex lens 3 that is positioned at barrel 2 front ends.These two single convex lens 5 are arranged on the position of lamp socket 6 the place aheads near barrel 2, and organize single convex lens the place ahead at this and be provided with a slot that is used to place lantern slide 11 near the position of single convex lens.In actual applications, lantern slide can be placed in the slide binder, and design slot big slightly, thereby be suitable for the insertion of slide binder.Three two groups of optical lenses of this slide projector comprise a slice biconvex lens and two single convex lens, and are all parallel to each other, and parallel to each other with the lantern slide that inserts in the slot, guarantee image quality.And each eyeglass all is to be fixed in the set groove of housing 1 or lens barrel 2 inwalls, and groove and eyeglass adopt interference fit, can guarantee the lens position precision again thereby play a part fixing len.
