Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of camera lens removing mechanism and using the optical device of the camera lens removing mechanism to solve existing skill
It is inconvenient to dismantle in art, the not high problem of reliability.It as depicted in figs. 1 and 2, is the structure of the camera lens part of optical device of the present invention
Schematic diagram, optical device include shell 300, the camera lens being fixed on shell 300 200 and camera lens removing mechanism 100.Camera lens removes
Mechanism 100 is located at the disassembly interface position of optical device camera lens, including the connection frame and transmission group being detachably connected with camera lens 200
Part, the grab and connecting pin that wherein camera lens 200 includes cooperate with clasp joint, can generate in connection frame when transmission component receives external force
To the thrust of lens direction, unlocking spring at camera lens is pushed, the disassembly of camera lens is then realized under the cooperation of related supplementary structure.
As shown in figure 3, be provided with connection frame 1 on the connection frame of camera lens removing mechanism 100, further, connection frame 1 can be with
With on camera lens 200 transmission parts or fixed agraffe be detachably connected, when transmission component stress, will push connection frame 1 along mirror
The optical axis direction of head is mobile, so that the transmission parts of camera lens 200 or fixed agraffe be driven to generate displacement.
Camera lens removing mechanism 100 further includes the bracket 2 for accommodating transmission component.Transmission component includes 3 He of first connecting rod
One end of second connecting rod 4, first connecting rod 3 and second connecting rod 4 is connected together through the hinges, so that first connecting rod 3 and second connects
Angle can change with the effect of external force between bar 4.Specifically, in use, external force is applied to first connecting rod 3 and second
At the connected hinge of connecting rod 4.Preferably, the forced section for receiving external force is provided at hinge, the transmission component will be described
The external force that forced section is born is converted into the motive force along optical axis direction.Further, second connecting rod 4 passes through far from one end of hinge
Screw 5 is movable to be fixed on bracket 2.In this way, in transmission component stress, since the fixing end of second connecting rod 4 is fixed on branch
On frame 2, therefore external force passes through the variation of angle between first connecting rod 3 and second connecting rod 4 and is transmitted to first connecting rod 3 far from hinge
One end forms the motive force along optical axis direction.
It should be noted that the fixed form of second connecting rod 4 is not limited to this, it can also be using other fixation sides such as buckles
Formula realizes the conversion of stress, i.e., as long as guaranteeing that 4 one end of second connecting rod is fixed and can pass to first connecting rod 3 by hinge
It can be implemented；In addition, so-called first connecting rod and second connecting rod are not particularly limited the structure of component, in fact, not
One be set to it is rod-shaped, it is plate, sheet, even blocky, as long as having corresponding structure, the object of the invention may be implemented be can be with
Implement.
Further, transmission component further includes that bullet is reversed in the offer for resetting first connecting rod 3 and 4 stress of second connecting rod
Property power dynamic clamping head and quiet clamping head 6, angle becomes larger after 4 stress of first connecting rod 3 and second connecting rod, is at this time that external force resists dynamic clamping head and quiet clamping head
The 6 elastic force actings generated, the tension between first connecting rod 3 and second connecting rod 4 is bigger, and the elastic force that dynamic clamping head and quiet clamping head 6 provides is bigger,
If 6 transmission device of dynamic clamping head and quiet clamping head is restored to the initial angle of first connecting rod and second connecting rod, that is, exists after external force disappears at this time
It does not stress down, angle when first connecting rod and second connecting rod are towards holder orientation realizes automatically reseting for camera lens removing mechanism.Bullet
Property return unit 6 can both be connected with first connecting rod 3, can also be connected with second connecting rod 4, specifically in the present embodiment, elasticity
Return unit 6 is arranged in the fixing end of the second connecting rod 4, and is assembled on bracket 2 by screw 5, and with 4 phase of second connecting rod
Even.In the present embodiment, dynamic clamping head and quiet clamping head 6 is torsional spring, can also be using other knots in selectable other embodiments
Structure, such as the spring of connection first connecting rod and second connecting rod, as long as can provide the elastic force of reset for transmission component, being can
With implementation.
Further, close to connection frame side, transmission component of the invention is additionally provided with one and is used for and 1 phase of connection frame
The sliding block 7 of cooperation, in the present embodiment, connection frame 1 are the connecting plate for being provided with through-hole, and sliding block 7 is set at least partially across through-hole
It sets, sliding block can apply active force on the camera lens grab with through-hole clasp joint, so that camera lens and releasing connection of winning in succession.Sliding block 7 is separate
One end of connecting plate is abutted against with first connecting rod 3, can be slided along the optical axis direction of camera lens under the driving of first connecting rod 3.To real
The power on first connecting rod 3 is now transmitted to connection frame 1 and then is transmitted at camera lens 200.Specifically, sliding block 7 is close to first connecting rod 3
Place is provided with to the fixing groove 71 being recessed far from 3 direction of first connecting rod, and first connecting rod 3 is inserted into the fixing groove far from the side of hinge
It in 71, and is further fixed by a bolt 8, to further increase the gearing of first connecting rod 4 Yu sliding block 7.
Further, the limiting section 41 for avoiding overstress is additionally provided on second connecting rod 4, it is corresponding, on bracket 2
It is provided with the limiting slot to match with limiting section 41.When external force is excessive, the angle between first connecting rod 3 and second connecting rod 4 is arrived greatly
When to a certain degree, limiting section 41 becomes larger with angle, the mobile limiting slot that can be touched on bracket 2 of second connecting rod 4, to keep away
Exempt from over-travel and torsional spring is caused to fail, improves the unfailing performance of product.
The present invention also provides a kind of optical device comprising above-mentioned camera lens removing mechanism, which includes for example, throwing
The projection device of shadow instrument etc. is, for example, capture apparatus of video camera, camera etc. etc., and camera lens removing mechanism 100 is set positioned at optics
The disassembly interface position of standby camera lens, including the connection frame and transmission component being detachably connected with camera lens 200, wherein camera lens 200 is wrapped
The grab included and connecting pin cooperate with clasp joint, can generate pushing away to lens direction in connection frame when transmission component receives external force
Power pushes unlocking spring at camera lens, and the disassembly of camera lens is then realized under the cooperation of related supplementary structure.
The beneficial effects of the present invention are: being in contrast to the prior art, the present invention provides a kind of camera lens removing mechanism, leads to
Cross change angle between the first connecting rod and the second connecting rod external force suffered by the transmission component is transmitted to it is described
Connection frame.The invention is convenient reliable, and transmission is laborsaving and relatively simple for structure, easy to assembly, cost is relatively low, practical.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
