This utility model belongs to the assistant devices field of camera, especially is acceptable for a kind of protective device to protect the camera view finder.
Camera has become the necessary equipment in people's life today, which adds a good many happy moment in life and records colorful life. With the popularization of camera, the assistant devices to provide various additional functions for it also become more and more. View finder is the most important part of camera, but most of what people commonly maintain and take care while in use is lens, and few people provide view finder with protection. Therefore, after using for a period of time, the view finer will be covered with dust, or more seriously, some of them may often suffer scuffing. The abovementioned phenomenons are common in former 120 cameras. For most of waist level finders, if there is not corresponding protective device, the view finder will be absolutely suffered with dust deposition and damage, and the accumulated dust is not easy to clean up, even more, the image on the view finder screen will not be seen clearly due to the interference of strong light and the view effect will be seriously affected. For the LCD view finder of digital camera in gradual popularization in recent years, because it is exposed outside directly, the abovementioned phenomenons of dust deposition and scuffing are more serious comparing with old-style 120 camera. At the same time, due to the specificity of LCD view finder, the observing effect is not good during side view, which is more serious under the condition of stronger sunlight.
The purpose of this utility model is to provide a protective device with dustproof and camera view finder protective functions to settle the abovementioned shortcomings. At the same time, this device also resolves the dust deposition and scuffing problems of LCD view finder of digital camera nowadays, which as well has a perfect effect to keep out the strong light and can be installed on the camera simply and conveniently.
The utility model realizes its functions through following technical proposals: One kind of LCD protective device is composed of frame and light screen installed on frame. The said frame adopts separate structure. There is a transparent plate installed in the middle part of frame and also a rotatable light screen set on the frame, which can be folded through the rotation. There is a rotatable cover plate on the other side of frame, which can cover the folded light screen. There is adhesive substance on the surface connecting the frame and camera body.
The said separate structure means that the frame is divided into at least two parts. There is a hooked protuberance on one part used to clamp the other part, and there is a notch matching to the abovementioned hooked protuberance on the corresponding position of the other part. The said notch is a gap whose one end is larger and the other end is smaller. The larger end is corresponding to the largest section of the hooked protuberance and the smaller one is matching to the smaller section of the hooked protuberance. The section of the said hooked protuberance connecting the frame is smaller and the other end section is larger. The said separate structure adopts to set magnet on one part of the frame composed of two parts, magnet or sheet iron on the other part.
The said adhesive substance is a belt with stickiness on both sides and is set along the outer fringe form of the transparent plate.
This utility model realizes following active technical effect through the abovementioned technical resolution: firstly, adopting the structure setting adhesive substance along the edge of the protective device, the protective device can be conveniently installed on the camera without help of any camera components, which can not damage the camera body effect and can make the camera view finder sealed well to prevent dust to enter. It can not affect the observation effect after the camera view finder sealed by adopting the structure to set transparent plate on protective device. It allows the protective device to be with perfect shading effect by adopting the structure to install light screen and cover plate on the protective device. With the structure of separate frame, the transparent plate of protective device can be protected, and at the same time, the shading part can be conveniently taken down under the condition without shading and it can realize various operations in different conditions.
As shown in
There is also another operating method for this utility model, of which, the main structure is generally same with the abovementioned structure except the different connection type of the separate-structure frame. What is adopted to use magnet attraction to finish the abovementioned connection. The specific structure adopts to set magnet on one of part of the abovementioned separate-structure frame, and magnet, sheet iron or other sheet metal which can be attracted by magnet on the other part. It can realize the installation and separation of the abovementioned frame's separate structure more conveniently through the abovementioned method.
