Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, snap-in structure 1 provided by the present invention, it comprises body 10 and the snap ring 12 that cooperatively interacts.Described body 10 comprises a lens through hole 100, and described lens through hole 100 has an edge 1001, and described snap ring 12 is fastened on 1001 places, edge of described lens through hole 100.
On the edge 1001 of described lens through hole 100, be formed with the engaging breach 102 of at least two symmetrical distributions.Side at least one described engaging breach 102 is formed with an elastic protrusion 104 and a positive stop 106.
Described elastic protrusion 104 comprises a link 1040 and a movable end 1041 that is connected with described link 1040.The link 1040 of described elastic protrusion 104 and adjacent described side 1020 flexible joints that engage breach 102.Movable end 1041 elasticity of described elastic protrusion 104 protrude in the plane 101 at described body 10 places.
Described positive stop 106 by the movable end 1041 of described elastic protrusion 104 outstanding and form to the edge 1001 of a side to the center of described lens through hole 100.Described elastic protrusion 104 is used for positive stop 106 that snap ring 12 positions on the lens through hole frontside edge 1001 to being fastened on.
Described snap ring 12 comprises engaging anchor ring 120 and is arranged on engaging on the anchor ring 120 at least two and engages breach 102 buckle 122 one to one with described.The external diameter of described engaging anchor ring 120 is greater than the diameter of lens through hole 100, and the internal diameter of described engaging anchor ring 120 is less than the diameter of lens through hole 100.Described engaging anchor ring 120 wall 1200 within it radially extends a flange 1201, and the inboard of described flange 1201 is along axial formation one ring wall 1203 of snap ring 12.Described buckle 122 is arranged at the edge that described flange 1201 engages with engaging anchor ring 120 evenly and at intervals.
Described buckle 122 comprises a holding parts 1220 and a holding section 1221.Described holding parts 1220 is formed along axially extending upward of this snap ring 12 by described flange 1201.Described holding section 1221 is formed by the top 1222 of described holding parts 1220 horizontal-extending radially outward along described snap ring 12.The end of described holding section 1221 forms the end face 1223 of a U type to increase the flexibility of buckle.
As Fig. 2, Fig. 3 and shown in Figure 4, in order to make described snap ring 12 and the barrel 13 that is installed in the lens through hole 100 keep concentric, when described body 10 cooperates with snap ring 12, make the holding parts 1220 of described buckle 122 cooperatively interact and pass corresponding engaging breach 102 making the described engaging anchor ring 120 and the edge 1001 of described lens through hole 100 cooperatively interact with seasonal described buckle 122 with the outer wall 130 of barrel 13.Leave a gap width F between the holding parts 1220 of described buckle 122 and the edge 1001 of lens through hole 100 to adjust the position between described snap ring 12 and the body 10.
Described buckle 122 rotates described snap ring 12 after passing described engaging breach 102 towards the side that described engaging breach 102 is provided with elastic protrusion 104 and positive stop 106.The holding section 1221 of described buckle 122 is rotated to movable end 1041 by the link 1040 of described elastic protrusion 104 and is made with the movable end 1041 that pushes described elastic protrusion 104 that thereby its edge 1001 maintenances with described lens through hole 100 are smooth to be made in the edge 1001 that described buckle 12 can turn to one section lens through hole 100 between described positive stop 106 and the elastic protrusion 104.After described elastic protrusion 104 was left in the holding section 1221 of described buckle 12, the movable end 1041 of described elastic protrusion 104 was upturned under the effect of elastic-restoring force to protrude in the plane 101 at described body 10 places.At this moment, described buckle 122 is located in one section edge 1001 between positive stop 106 and the elastic protrusion 104.The holding section 1221 and the body 10 of described buckle 122 have one section fastening amount H that cooperatively interacts.
In the present embodiment, equal the width s (as shown in Figure 1) of described buckle 122 apart from S between the movable end 1041 of described positive stop 106 and described elastic protrusion 104, the radical length h of the holding section 1221 of described buckle 122 equals described fastening amount H and described gap width F sum, the length L at edge 1001 that described positive stop 106 protrudes in described lens through hole 100 greater than the thickness l of the holding parts 1220 of described buckle 122 and described gap width F sum so that described positive stop 106 and elastic protrusion 104 position buckle 12 better.
Snap-in structure 1 provided by the present invention is by engaging breach 102 and make snap ring 12 and body 10 closely cooperate buckle 122 being set on the snap ring 12 and being provided with on body 10 with buckle 122 is corresponding, and general positive stop 106 and the elastic protrusion 104 that is installed in the barrel 13 in the lens through hole 100 and is arranged on the edge 1001 of lens through hole 100 locate snap ring 12 exactly, effectively avoids the eccentric error between snap ring 12 and the barrel 13.Secondly, because adopted buckle 122 and the cooperation that engages breach 102, also be easy to dismounting after snap ring 12 is fixed with body 10 and be convenient to maintenance.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
