Abstract
The invention discloses a lens protection front cover. The shell of the front cover is made of elastic PVC material. The inner side of the shell of the front cover is provided with a limiting boss and a buckling protruded ring. The limiting boss is positioned closer to the bottom of the shell of the front cover. The buckling protruded ring is arranged on the edge of the inner side of the shell of the front cover. When the shell of the front cover is buckled onto a lens, the limiting boss abuts against the front edge of the lens. At the same time, the rear side edge of the lens is clamped by the buckling protruded ring. In this way, the lens protection front cover is buckled onto the lens. In addition, the bottom of the shell of the front cover is provided with a yielding cavity, so that the damage to the lens caused by the contact between the bottom of the shell of the front cover and the front side surface of the lens can be effectively avoided. The lens protection front cover is simple in structure, convenient in assembly and disassembly and practical.
Description
[technical field]
The present invention relates to lens protecting apparatus, especially a kind of lens protection protecgulum.
[background technology]
In use, the end is easily damaged.When not using, usually need hitch one protection protecgulum on camera lens, in the prior art, this protection protecgulum easily comes off; In addition, when protecting protecgulum cover to be buckled on camera lens, camera lens is then easily touched in the bottom of protection protecgulum, causes and easily damages eyeglass.
Namely the present invention researchs and proposes for the deficiencies in the prior art.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of lens protection protecgulum, protecgulum housing adopts elasticity plastic uptake material to make, when protecgulum housing snaps onto on camera lens, positive stop lug boss then abuts the forward edge with camera lens, buckle bulge loop then blocks the rear end side of camera lens, and the present invention is firmly snapped onto on camera lens; Dodge cavity in addition at protecgulum housing bottom, effectively prevent protecgulum housing bottom and touch front side lens face and the problem of damaging camera lens, the present invention has the advantages that structure is simple, be convenient to dismounting and practicality.
For solving the problems of the technologies described above; a kind of lens protection protecgulum of the present invention; comprise the side opening be made up of elasticity plastic uptake material and protecgulum housing cylindrically; described protecgulum case inside wall is circumferentially provided with positive stop lug boss; described protecgulum case inside edge is circumferentially provided with buckle bulge loop, is provided with and dodges cavity bottom described protecgulum case inside.
Described protecgulum case inside wall is provided with air discharge duct vertically.
Described positive stop lug boss is circumferentially laid with three.
Described buckle bulge loop is circumferentially laid with three.
Described air discharge duct one end extends to protecgulum housing bottom, and the other end extends to protecgulum shell rim.
Described air discharge duct is circumferentially laid with three.
Compared with prior art, a kind of lens protection protecgulum of the present invention, tool has the following advantages:
1, protecgulum housing adopts elasticity plastic uptake material to make, and by elastic deformation, camera lens then blocks in protecgulum housing by buckle bulge loop securely.
2, the positive stop lug boss be located in protecgulum housing is connected to front side lens limit, and protecgulum housing bottom is touched and scratch camera lens in the front side lens face avoided.
3, for avoid camera lens to touch the bottom surface of protecgulum housing further, be provided with in the bottom surface of protecgulum case inside and dodge cavity, when protecgulum housing distortion, make the bottom of protecgulum housing still keep contactless state with front side lens face, be conducive to len.
4, in order to smooth and easy when snapping, be then provided with air discharge duct vertically at described protecgulum case inside wall, the air in protecgulum housing effectively can be discharged by air discharge duct, ensure that snapping is firm further.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, wherein:
Fig. 1 is one of stereographic map of the present invention.
Fig. 2 is stereographic map two of the present invention.
Fig. 3 is the schematic diagram before the present invention snaps onto camera lens.
Fig. 4 is the schematic diagram of the present invention and camera lens snapping.
Fig. 5 is that the present invention completes the schematic diagram snapped onto on camera lens.
[embodiment]
Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated.
As depicted in figs. 1 and 2; a kind of lens protection protecgulum of the present invention; comprise the side opening be made up of the rare plastic matter of elasticity and protecgulum housing 1 cylindrically; protecgulum housing 1 can be made up of PET or PVC material; described protecgulum housing 1 madial wall is circumferentially provided with positive stop lug boss 2; described protecgulum housing 1 inside edge is circumferentially provided with buckle bulge loop 3, and described protecgulum housing 1 inside bottom is provided with dodges cavity 4.During snapping, by elastic deformation, camera lens 6 blocks in protecgulum housing 1 by buckle bulge loop 3 securely; For the bottom surface avoiding camera lens 6 to touch protecgulum housing 1 further; bottom surface inside protecgulum housing 1 arranges and dodges cavity 4; when protecgulum housing 1 is out of shape, makes the bottom of protecgulum housing 1 still keep contactless state with camera lens 6 leading flank, be conducive to len 6.
In order to smooth and easy when snapping, then be provided with air discharge duct 5 vertically at described protecgulum housing 1 madial wall, air in protecgulum housing 1 effectively can be discharged by air discharge duct 5, ensure that snapping is firm further, produce negative pressure when it also avoid dismounting simultaneously and dismantle inconvenient problem; In the present embodiment, described air discharge duct 5 is circumferentially laid with three.
In the present embodiment, in order to positive stop lug boss described in stress balance 2 is circumferentially laid with three; Described buckle bulge loop 3 is circumferentially laid with three; Described air discharge duct 5 one end extends to bottom protecgulum housing 1, and the other end extends to protecgulum housing 1 edge.
When adopting the present invention to snap onto camera lens 6, as shown in Figures 3 to 5, during snapping, buckle bulge loop 3 produces deformation, and the press-in of 6, camera lens is to protecgulum housing 1 centre position, and in process of press in, the air in protecgulum housing 1 is then discharged by air discharge duct 5.When camera lens 6 is pressed into by continuation, until camera lens 6 leading flank edge touches positive stop lug boss 2, then complete snapping action.
