Description

A kind of LCDs protective device of button

[technical field]

The utility model relates to a kind of digital camera servicing unit, refers in particular to a kind of digital camera LCDs protective device with button web member.

[background technology]

An important difference of digital camera and traditional camera is exactly that it has a LCDs (Liquid Crystal Display; LCD), it makes that the shooting of digital camera is more convenient and simple and since LCDs shown be from optical charge coupled apparatus (Charge CoupleDevice; CCD) go up received image, the scenery that can use LCDs observation post to take is found a view and can be adjusted immediately when improper, has avoided general camera to use the parallax that optical finder brought; Shown picture is the final actual photographed picture that will be recorded on the memory body on the LCDs, can obtain to be similar to the effect of " What You See Is What You Get " of slr camera; LCDs makes photographer can know shooting effect immediately, and when the effect of captured personage, landscape etc. did not reach photographer's expectation, deleting retakes got final product, and has avoided the worry of using traditional film to regret after flushing.But LCDs has the shortcoming of the ambient light effects of being subject to, and is special more obvious in the power supply deficiency, and when surround lighting such as solar irradiation were mapped to LCDs, the image of its demonstration can not clearly be differentiated, and causes the reduction significantly of shooting effect.

For solving the problem that LCDs in use is subject to ambient light effects, people develop light-baffling device to be used to block the surround lighting that shines during the shooting on the LCDs.Include as a kind of LCDs light-baffling device of commonly seeing: be fixed to the LCDs housing web member, be rotatably installed in as described in the light blocking part up and down of web member upper inside, and the side and the opposite side light blocking part that have flexibly, be rotatably installed in the inner left and right sides of described web member, during taking, this light-baffling device can block the exterior light that incides LCDs.

Though above-mentioned light-baffling device of commonly seeing also can apply to digital camera to work the purpose of blocking the exterior light that incides LCDs, but such light-baffling device of commonly seeing exists the shortcoming of installation or removal inconvenience, and in the use of digital camera, LCDs easily attaches trickle things such as sand and dust, dust, also exist the problem that is easily scratched LCDs by hard thing, thereby influence the display effect of LCDs, even shorten its serviceable life.

[summary of the invention]

The purpose of this utility model is to provide a kind of easy to use, digital camera LCDs protective device that can make LCDs avoid ambient light effects and have dustproof and anti-scratch function.

The purpose of this utility model is achieved by the following technical solution: the LCDs protective device of this button includes slide that button web member, that a frame-saw, is arranged on the frame-saw outside surface is arranged on the inboard of frame-saw, and is installed in last light barrier, and left and right sides in frame-saw first light barrier and second light barrier that are provided with in rotatable and flexible mode of frame-saw inside upper part in rotatable mode.

Advantage of the present utility model is: the button web member makes that the use of protective device is more easy; Not only can make during the shooting LCDs of digital camera avoid the influence of surround lighting, and have the function that the protection LCDs is avoided trickle thing influence such as dust, avoided scratching.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 2 is the structural representation of frame-saw of the LCDs protective device of a kind of button of the utility model.

Fig. 3 is the user mode synoptic diagram of the LCDs protective device of a kind of button of the utility model.

[embodiment]

As shown in Figure 1 and Figure 2; this protective device includes the button web member 12 that a frame-saw 10 and is arranged on frame-saw 10 outside surfaces; this button web member 12 is made of a web member once 120 and a rotatable upper connector 122 that is formed at frame-saw 10 outside surfaces; these upper connector 122 1 ends are formed with perforate; use latch 126 to realize that this upper connector 122 and one is formed at being connected of connection bump 124 frame-saw 10 outside surfaces, that perforate is arranged, this web member 122 serves as that axle is rotated with latch 126.Described upper connector 122 1 ends are formed with a recess 121, and following web member 120 is formed with a projection 123, and this projection 123 is complementary with recess 121.With web member 12 be seated in the digital camera back side such as protrusion member places such as view finders, rotation upper connector 122 inserts in the recess 123 projection 121, make web member 12 fasten the protrusion member of digital camera, can realize that protective device is connected to the LCDs place of digital camera; Apply an external force at upper connector 122, make projection 121 break away from recess 123, can take off this protective device.

Left side at the inside surface rear portion of frame-saw 10 is formed with a pair of hinged protruding 100, this has perforate in hinged protruding 100, the upper and lower of first light barrier, 14 1 sides is formed with a jointed shaft 140, jointed shaft 140 inserts in hinged protruding 100 the perforate, and be provided with a spring 142 in a side, realize that first light barrier 14 can carry out the elasticity rotation; Right side at rear portion, the inside surface of frame-saw surface is formed with a pair of hinged protruding 102, this has perforate in hinged protruding 102, the upper and lower of second light barrier, 16 1 sides is formed with a jointed shaft 160, jointed shaft 160 inserts hinged protruding 102 perforate, and be provided with a spring 162 in a side, realize that second light barrier 16 can carry out the elasticity rotation.

The left and right sides on the inside surface top of frame-saw 10 respectively is formed with a poroid depression 104, the left and right sides on last light barrier 18 tops respectively is formed with a columnar projections 180, columnar projections 180 is inserted in the poroid depression 104, and light barrier 18 can be that the axle center is rotated with the axle center at columnar projections 180 places in the realization.

The inboard of frame-saw 10 is provided with a slide 20, and this slide 20 can be by the inboard of adhesives in frame-saw 10.This slide 20 can be the optical glass slide, also can be the PVC slide, certainly, also can be the slide that other materials is made, but it must have the high characteristics of transparency, observes the shown content of LCDs so that the user sees through this slide 20.When using this digital camera LCDs protective device, slide 10 is covered on the LCDs, thereby avoids trickle things such as dust, sand and dust to adhere to LCDs, also can avoid LCDs to be scratched by hard thing.

Be formed with a recess 106 in the middle of the bottom of frame-saw 10, be formed with a projection piece 182 in the middle of the bottom of last light barrier 18, this recess 106 is a bit larger tham projection piece 182, so that the user opens light barrier 18.Be formed with a plurality of stop protrusion 184 on the lower external face of last light barrier 18, the inside surface of frame-saw 10 bottoms is formed with a plurality of depressions 108, and this stop protrusion 184 is complementary with depression 108.Be rotated down light barrier 18, stop protrusion 184 is inserted in the depression 108, realizes the firmly closed light barrier 18 of going up.

In conjunction with shown in Figure 3; with button web member 12 fasten the digital camera back side such as projecting parts such as view finders; realize that this protective device is fixed in the LCDs place of digital camera; thereby pulling projection piece 182 makes stop protrusion 184 break away from depression 108 and opens light barrier 18; because the disengaging of last light barrier 18; first light barrier 14 and second light barrier 16 are subjected to spring 142; 162 elastic acting force and opening; last light barrier 18; the part that first light barrier 14 and second light barrier 16 are formed can stop shine LCDs such as exterior light such as sunshines; slide 20 is covered on the LCDs; can block trickle thing such as dust and be attached on the LCDs, and can avoid display screen to be scratched by hard thing.
