Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 and fig. 2, a lens filter holder according to an embodiment of the present invention includes a lens adapter ring 1 and a filter holder 2, the filter holder 2 is provided with a through hole 3 and an annular adapter ring mounting groove 4 concentric with the through hole 3, the filter holder 2 is further provided with at least one positioning fixture block 41 extending into the annular adapter ring mounting groove 4 (the specific structure may be that at least one positioning fixture block 41 extending toward the axial direction of the annular adapter ring mounting groove 4 is further provided at the annular groove edge of the adapter ring mounting groove 4, and of course, the positioning fixture block 41 may also be an independent component, and is fixed on the filter holder 2 by a locking member such as a screw and extends into the annular adapter ring mounting groove 4); simultaneously the circumference side of filter support 2 is equipped with locking seat 5, locking screw 6 and lock nut 7, wherein be equipped with locking limit position 8 on the locking seat 5, but locking screw 6 axial motion and automatic axial inwards reset ground pass locking seat 5, locking limit position 8 and filter support 2's circumference side in proper order, and locking screw 6's end is equipped with the locking portion 9 that stretches into annular adapter ring mounting groove 4, lock nut 7 locates in locking limit position 8 and overlaps on locking screw 6 matchingly. The concrete structure can be as follows: the number of the positioning fixture blocks 41 is two, and the two positioning fixture blocks 41 are arranged on the groove edge of the annular connecting ring installation groove 4 opposite to the locking part 9 at intervals; the locking seat 5 can be a convex block arranged on the circumferential side surface of the filter support 2, the locking limiting position 8 is a limiting hole penetrating through the front side surface and the rear side surface of the convex block, the locking nut 7 is arranged in the limiting hole and is sleeved on the external thread part of the locking screw 6 in a matching way, and the circumferential side surface part of the locking nut 7 extends out of the locking limiting position 8; locking portion 9 adopts the plastic material preparation to form, and its one end that stretches into in annular flange mounting groove 4 is equipped with the circular arc draw-in groove 91 with the marginal matching of camera lens flange 1, moreover locking screw 6 is equipped with the one end of locking portion 9 and still overlaps and has reset spring, reset spring's both ends are connected with locking portion 9 and filter support 2 respectively.
When the lens adapter 1 and the filter holder 2 are assembled together, the lens adapter 1 is rotatably assembled on the annular adapter mounting groove 4 of the filter holder 2 through the positioning fixture block 41 and the locking portion 9, specifically, the edge of the lens adapter 1 is movably clamped in the circular arc clamping groove 91 and the gap between the positioning fixture block 41 and the annular adapter mounting groove 4, so that the lens adapter 1 is rotatably assembled on the annular adapter mounting groove 4 of the filter holder 2, and the edge of the lens adapter 1 is in sliding contact with the circular arc clamping groove 91 at this time. When the locking nut 7 is screwed to the outermost end of the locking limiting position 8 and props against the outermost end of the locking limiting position, the locking screw 6 is driven to move axially inwards, the locking part 9 is tightly attached to the edge of the lens adapter ring 1 to lock the locking screw 6, locking between the rotatably connected lens adapter ring 1 and the filter support 2 is realized, and meanwhile, the reset spring is compressed; conversely, when the locking nut 7 is screwed to be separated from the outermost end of the locking limiting position 8, the spring drives the locking screw 6 to move axially outwards, so that the arc clamping groove 91 of the locking part 9 and the edge of the lens adapter ring 1 are restored to be in sliding contact connection, the locking screw 6 is unlocked, and the lens adapter ring 1 and the filter lens bracket 2 which are connected in a rotating manner are unlocked; if the locking nut 7 is screwed to the innermost end which is propped against the locking limiting position 8, the locking screw 6 is manually pushed outwards in the axial direction, and then the lens adapter ring 1 and the filter support 2 can be detached.
Thus, the camera lens filter support can realize through operation locking screw 6 and lock nut 7 that camera lens adapter ring 1 and filter support 2 dismouting, realization are rotated locking and unblock between camera lens adapter ring 1 and the filter support 2 of being connected, and the operation is very simple, convenient, swift, and locking portion 9 also can not cause wearing and tearing to camera lens adapter ring 1 simultaneously, stable performance, reliable, and locking structure is simple, compact moreover, and the production and processing is easy, has very strong market competition.
In addition, the filter holder 2 is provided at positions corresponding to the locking portions 9 at the inside and the surface thereof with first and second guide grooves 42 and 43 extending to the bottom surface of the annular flange mounting groove 4 and the groove sides of the annular flange mounting groove 4, and the locking portions 9 are movably caught at the front and rear sides thereof in the first and second guide grooves 42 and 43. Thus, the movement stability of the locking portion 9 can be greatly improved by the first guide groove 42 and the second guide groove 43, and the performance is more stable and reliable.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
