Description
Technical field
The utility model relates to a kind of being external in and connects the order magnifier of finding a view on slr camera eyepiece, is specifically related to a kind of order magnifier web member of finding a view that connects.
Background technology
The principle that existing slr camera is found a view, is after the reflection of pentaprism or pentamirror, refraction, and the viewfinder window of photographer by camera itself realizes that photograph finds a view.During photograph, human eye must just can be found a view near the viewfinder window on camera.When accurately focusing of needs, macroshot, reproduction file, in little aperture situation, because the light by unthreaded hole is less, often there is unreal or the situation that cannot focus of focus in automatic camera automatic lens; And manually camera lens also can be less because of existing view finder magnification, or the situation such as light is dark, by viewfinder window, focus and also often have the shortcoming that focus error is large, waste time and energy.In order to address the aforementioned drawbacks, application number: 20092008976.9 utility model patent, a kind of eye lens amplifier is disclosed, the side of comprising turns round interface, and side turns round interface and is connected with amplifier; Side turns round interface and consists of square claw and round thread interface; Amplifier forms by amplifying lens barrel, convex lens, focal length ring, concavees lens and pressure ring, the inside of amplifying lens barrel is provided with convex lens successively, focal length ring and concavees lens, amplifier lens barrel is provided with the seam projection that is less than amplifier lens barrel internal diameter in one end, outside of convex lens; Amplifier lens barrel is provided with pressure ring in one end, outside of concavees lens.
Above-mentioned eye lens amplifier in use, first side is turned on the viewfinder window that round interface is plugged on slr camera, then the other end spiral that turns round interface in side enters the body of eye lens amplifier, human eye is by one end of amplifier body, see through the concave, convex mirror that amplifier inside sets gradually, the scenery of observing from viewfinder window is further amplified, and in this process in order to watch the length of more clear rotatable resonance-amplifier itself to rotate zoom.Thereby make it have, can in the situation that not producing dark angle, effectively amplify the function of the image showing in view finder of camera, make the image after amplifying there is more clear and more easily accurately focusing; Yet, in rotation zoom process, because eye lens amplifier body and side turn round interface, is connected insecurely, and easily occur directly from just turning round interface rotation, splitting away off the body of eye lens amplifier, thereby cause the situation of eyeglass breakage.
In order to solve eye lens amplifier body and side turns round interface and is connected unstable problem, application number: 20132031040.8 utility model patent, a kind of Novel connecting eyepiece amplifier is disclosed, as shown in Figure 1, comprise an end face and be provided with recessed, the amplifier body of convex lens (D1) is spirally connected, other end and the camera side that position mates of finding a view turns round interface (D2), described side turn round interface (D2) be provided be spirally connected with amplifier body after by regulating the lockable mechanism of the amplifier body that can lock, described lockable mechanism comprises that the side of running through turns the screw (D3) of round interface screw socket mouth wall, one bolt mating with screw or screw (D4).This kind, eye lens amplifier is by turning on round interface lockable mechanism is set in side, make amplifier body because of the place's locking that is spirally connected, no matter how it rotates adjusting, can not produce and slide and dislocation, thereby effectively avoided the amplifier body damage that can drop to the ground, and the place's of being spirally connected displacement causes the generation of the situations such as too much trouble to user, yet the bolt of the lockable mechanism of this kind of eye lens amplifier or screw are when installation or removal, need to be by instrument, thereby brought inconvenience to user, and lockable mechanism is the friction force of utilizing bolt or the top of screw (D4) and the screw thread place of amplifier body to produce, realization is by amplifier body locking, for guaranteeing that bolt or the top of screw (D4) and the screw thread place of amplifier body have enough large friction force, just need to make the top of bolt or screw (D4) produce enough large pressure to the screw thread place of amplifier body, will cause like this screw thread of amplifier body impaired, thereby affect the normal installation and removal of amplifier body.
Therefore, we need a kind of when installation or removal without by other instruments, and can not cause damage to amplifier body, installation or removal are the Novel connecting order magnifier web member of finding a view easily.
Summary of the invention
The purpose of this utility model is to solve in prior art, connect the order magnifier web member of finding a view, need to be by other instruments when installation or removal, installation or removal are inconvenient, and easily amplifier body is caused the problem of damage, when a kind of installation or removal are provided, without by other instruments, installation or removal are convenient, and that can not cause damage to amplifier body connects the order magnifier web member of finding a view.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of order magnifier web member of finding a view that connects, comprise that amplifier body and side turn round interface, described amplifier body adjacent end outer wall is provided with outer connecting thread, described side turns round interface adjacent end inwall and is provided with interior connecting thread, described outer connecting thread is identical with interior connecting thread rotation direction, described amplifier body turns round interface with side and is realized and being threaded with the mating reaction of interior connecting thread by outer connecting thread, it is characterized in that: this connects the order magnifier web member of finding a view and also comprises retaining ring, described retaining ring is connected in amplifier body by reverse thread and side turns round interface.
