Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 to Fig. 3, the utility model provides a kind of moving lens device 10, comprise camera lens 20 and move the installation portion 30 of setting for camera lens 20, between camera lens 20 and installation portion 30, be arranged at intervals with mobile space 40, further, moving lens device 10 also comprises and being located on installation portion 30 in order to seal mobile space 40 and can follow the dust guard 50 that camera lens 20 moves.By being provided with dust guard 50 on the mobile space 40 forming between camera lens 20 and installation portion 30, can effectively prevent that dust, water droplet or other larger particle from arbitrarily entering the inside of moving lens device 10 from mobile space, avoid the inner member (as making inner member occur the problems such as aging, oxidation) of the stained moving lens device 10 of introduced contaminants, thereby guarantee preferably the serviceable life of moving lens device 10.
Refer to Fig. 4, dust guard 50 comprises the dustproof sponge 50a that is inserted in camera lens 20 and seals mobile space 40, dustproof sponge 50a offers for it and is inserted in the opening 51 of camera lens 20, usually, because dust guard 50 is mainly dustproof sponge 50a, and dustproof sponge 50a itself has certain retractility, so, in order to guarantee that dustproof sponge 50a can compact, be inserted in camera lens 20, the width of the opening 51 of offering is less than the width of camera lens 20.
Further, dustproof sponge 50a is provided with from outer toward interior and extend to the otch 52 of opening 51 in one side, so, when dustproof sponge 50a is inserted in to camera lens 20, can be by otch 52, convenient dust-proofing sponge 50a is inserted in camera lens 20, avoids offering the too little situation that racks dustproof sponge 50a that there will be while being inserted in camera lens 20 because of the width of opening 51.
Refer to Fig. 5, preferably, for fear of dustproof sponge 50a, because of the too soft situation that occurs easily distortion, displacement, the dustproof sponge 50a of the present embodiment is provided with one and prevents the anti-deformation sheet 53 that dustproof sponge 50a is out of shape on the lower surface of the upper surface with respect to the exposed external world.
Particularly, anti-deformation sheet 53 is established along the edge extended loop of dustproof sponge 50a lower surface, and this anti-deformation sheet 53 offer corresponding with opening 51 first dodge mouthfuls 531 and with corresponding second the dodging mouthfuls 532, the first and dodge mouthfuls 531 and second and dodge mouth 532 and be and be communicated with setting of otch 52.Mainly, the anti-deformation sheet 53 of the present embodiment and the shape Corresponding matching of dustproof sponge 50a, simultaneously can not affect the effect of opening 51, otch 52 yet, for this reason, on anti-deformation sheet 53, offer first and dodge mouthful 531, second and dodge mouthfuls 532 to avoid opening 51, otch 52.Side by side, first dodges the width that mouthfuls 531 width is greater than opening 51, and second dodges the width that mouthfuls 532 width is greater than otch 52, can implement smoothly when guaranteeing that dustproof sponge 50a is inserted in camera lens 20 by opening 51, otch 52.
Further, anti-deformation sheet 53 is PC plastic sheet.Wherein, PC is the amorphous polymer of almost colourless glassy state, have have well optical, and PC material has good flame-retardance, wear-resisting, inoxidizability, and the present embodiment adopts PC plastic sheet to be not only that as anti-deformation sheet 53 it is drawn materials conveniently, cost performance is high, and be convenient to be attached on the lower surface of dustproof sponge 50a.
Particularly, the periphery of the dustproof sponge 50a of the present embodiment and the inwall of installation portion 30 are set in distance, be mainly, dustproof sponge 50a be placed on to the centre of camera lens 20, so, when camera lens 20 is when four direction moves up and down, dustproof sponge 50a just can follow camera lens 20 and move, and dustproof sponge 50a surrounding reserves free gap, neither can interfere with dilapidated walls or other inner members of installation portion 30, also can not affect the dust-proof effect of dustproof sponge 50a.
The utility model also provides a kind of projector, has above-mentioned moving lens device 10.
Below in conjunction with diagram, the course of work that dustproof sponge 50a of the present utility model is arranged on to moving lens device 10 is further described:
First, according to being arranged at intervals with the size of mobile space 40 between camera lens 20 and installation portion 30, set the size of dustproof sponge 50a, preferably guarantee when dustproof sponge 50a is located at installation portion 30 to leave gap with the inwall of installation portion 30; And then according to the size of camera lens 20, on the surface of dustproof sponge 50a, offer opening 51; Then, the side at dustproof sponge 50a is provided with otch 52 from the outer opening 51 that extends to toward in; Afterwards, on the lower surface of dustproof sponge 50a, attach PC plastic sheet, with this, avoid dustproof sponge 50a to deform; After complete, just can dustproof sponge 50a be inserted in to camera lens 20 by otch 52, like this, when camera lens 20 moves, dustproof sponge 50a just can follow camera lens 20 and move, and effectively stops that extraneous dust, earth or other larger foreign matter enter the inside of moving lens device 10.
The foregoing is only the utility model preferred embodiment; its structure is not limited to the above-mentioned shape of enumerating; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
