The specific embodiment
About aforementioned and other technology contents, feature and effect of the present invention, in the detailed description of a preferred embodiment that coordinates below accompanying drawing, can clearly understand.
Consult Fig. 2,3,4, for the present invention has the preferred embodiment of the sight of telescopic cone, this sight with telescopic cone comprises: urceolus 10, cam canister 20, rotary stopper assembly 30, cone unit 40, directly enter spacing assembly 50, circlets 60 and protection urceolus 70.
This urceolus 10 vertically X extends, and has far vane portion 11, and is arranged at the objective lens group 12 in this far vane portion 11.Be noted that in the present embodiment, just this urceolus 10 of Local Representation, therefore, does not disclose the known tip assemblies that other is applied to sight, for example, and ocular lens group, zoom mechanism or impact correcting mechanism ... etc..
This cam canister 20 is sheathed on this far vane portion 11 rotationally, and have the first front end 21, the first rear end 22, from this first front end 21 extend to this first rear end 22 the first inner peripheral surface 23, in contrast to the first outer peripheral face 24 of this first inner peripheral surface 23, two, be oppositely arranged and contrary and run through respectively the cam guide channel 25 of this first inside and outside side face 23,24 each other, and two intervals arrange and run through respectively the installing hole 26 of this first inside and outside side face 23,24.
These cam guide channels 25 have respectively and are adjacent to this first front end 21 the front limit section 251 of along the circumferential direction extending, are adjacent to this first rear end 22 rear spacing section 252 of along the circumferential direction extending, and connect this forward and backward spacing section 251,252 linkage section 253.
This rotary stopper assembly 30 has two limited screws 31 that are arranged at intervals at the far vane portion 11 of this urceolus 10, and be formed at the first inner peripheral surface 23 of this cam canister 20 and be adjacent to the spacing circular groove 32 of this first rear end 22, these limited screws 31 are slidably matched with this spacing circular groove 32 respectively, and overlap.In the present embodiment, these installing holes 26 correspond respectively to these limited screws 31, and are communicated with this spacing circular groove 32, and these installing holes 26 can pass this cam canister 20 for these limited screws 31, and are locked in this far vane portion 11.
This cone unit 40 has far vane portion 11 cone 41 between this far vane portion 11 and this cam canister 20 that is sheathed on movably this this urceolus 10 along this axial X, and two pilot pins 42 that are relatively arranged on this cone 41 and are connected with these cam guide channels 25 respectively.This cone 41 has the second front end 411, the second rear end 412, and from this second front end 411, extends to the second inner peripheral surface 413 of this second rear end 412.
This directly enters spacing assembly 50 and has the spacing guide block 51 that is arranged at far vane portion 11 outsides of this urceolus 10 and radially protrudes outwardly, and along this axial X-shaped, be formed in the straight line guide channel 52 of the second inner peripheral surface 413 of this cone 41, this spacing guide block 51 is slidably matched with this straight line guide channel 52, and overlaps.
This circlets 60 is arranged at the second front end 411 of this cone 41 and is spirally connected with this second inner peripheral surface 413, and this circlets 60 can be decorated this cone 41.
This protection urceolus 70 is sheathed on the first outer peripheral face 24 of this cam canister 20.In the present embodiment, the material of this protection urceolus 70 is rubber, and this protection urceolus 70 can cover these cam guide channels 25 and these installing holes 26, to produce the effect of decorating with waterproof, and can prevent that light from seeing through these cam guide channels 25.Preferably, this protection urceolus 70 has the friction bulge loop 71 that number is arranged at intervals at outside.
Rotate this cam canister 20 and can drive these pilot pins 42 through these cam guide channels 25, and order about this cone 41, with respect to this far vane portion 11, between retracted position (seeing Fig. 3,4) and extended position (seeing Fig. 5,6), move, when this cone 41 is during at this retracted position, these pilot pins 42 are connected with rear spacing section 252 of these cam guide channels 25 respectively, so that this cone 41 is positioned to this retracted position, now, this second front and back ends 411,412 is respectively adjacent in this first front and back ends 21,22; On the contrary, when this cone 41 is during at this extended position, these pilot pins 42 are connected with the front limit section 251 of these cam guide channels 25 respectively, so that this cone 41 is positioned to this extended position, now, this second front end 411 is away from this first front end 21, and this second rear end 412 is adjacent to this first front end 21.
By this, as shown in Figure 5,6, when user will avoid aiming to be subject to the interference of other light, user can protect urceolus 70 through this and rotate these cam canisters 20, and order about this cone 41 and move to this extended position forward, and the effect of generation shading; On the contrary, as shown in Figure 3,4, when user does not need to use this cone 41, can protect urceolus 70 through this and rotate this cam canister 20, order about this cone 41 and move to this retracted position backwards.
Via above explanation, can again advantage of the present invention be summarized as follows:
One, the present invention can utilize this cam canister 20 to order about this cone 41 to move between this retracted position and this extended position, when user wants to use this cone 41, can at any time this cone 41 be produced to use, when user does not want to use this cone 41, also can at any time this cone 41 be turned and be closed between this cam canister 20 and this urceolus 10, to dwindle entire length of the present invention, therefore, compared to the known sight with circumscribed cone, the present invention can avoid user and additionally carry the inconvenience of taking in.
Two, when this cone 41 is during at this retracted position and this extended position, these pilot pins 42 can be respectively connected with front limit section 251 with rear spacing section 252 of these cam guide channels 25, so that this cone 41 is positioned respectively to this retracted position and this extended position, therefore the impact that, the present invention can effectively avoid gun to produce when shooting causes this cone 41 improper shifts.
In sum, the sight with telescopic cone of the present invention, not only can avoid user and additionally carry the inconvenience of taking in, and cone is when gun is shot, and can be held in location, therefore really can reach object of the present invention.
The foregoing is only preferred embodiment of the present invention, can not limit scope of the invention process with this, i.e. all simple equivalences of doing according to the claims in the present invention and invention description content change and modify, and all still remain within the scope of the patent.
