Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment mono-
Please refer to Fig. 3 and Fig. 4, wherein, in the camera lens that Fig. 3 provides for the utility model embodiment mono-, regulate the cross-sectional schematic of driving lever and main cylinder junction; The structural representation of main body tube in the camera lens that Fig. 4 provides for the utility model embodiment mono-.The camera lens that the present embodiment one provides comprises: mounted inside has the main cylinder 2 of set of lenses 1, the outer main body tube 4 being fixedly connected with the shell 3 of camera lens that is arranged with of main cylinder 2, and the tube wall of main body tube 4 has one section of first chute 41 circumferentially extending along main body tube 4; The outer sheathed adjustable ring 5 rotationally of main body tube 4, adjustable ring 5 is slidably matched to promote the main cylinder 2 axial line a directions along main body tube 4 with main cylinder 2 and moves; Adjustable ring 5 is provided with a screwed hole 51 corresponding with the first chute 41, this screwed hole 51 adjusting driving lever 6 that is threaded, and regulate the inner of driving lever 6 through screwed hole 51, be placed in the first chute 41 slidably.
It should be noted that: generally, in camera lens, main cylinder 2 can only move along the direction of axis line of main body tube 4, can not rotate around the axial line a of main body tube 4; Adjustable ring 5 can only rotate around the axial line a of main body tube 4, can not move along the direction of axis line of main body tube 4.
In the camera lens that the present embodiment provides, regulate the inner of driving lever 6 through the screwed hole 51 on adjustable ring 5, be placed in the first chute 41 of main body tube 4, in the time of need to regulating the focal length of video camera, promote to regulate driving lever 6, regulate the inner of driving lever 6 to slide along the first chute 41, and drive adjustable ring 5 to rotate around the axial line a of main body tube 4, to drive main cylinder 2 direction of axis line along main body tube 4 to move, thereby regulate the distance between image inductor in set of lenses 1 in main cylinder 2 and video camera, regulate the focal length of video camera.After focus adjustment is good, to the direction of axis line of main body tube 4, screws and regulate driving lever 6, make to regulate the inner of driving lever 6 and the outer wall of main cylinder 2 to offset, thereby main cylinder 2 and adjustable ring 5 are fixed.
Hence one can see that, in the camera lens that the present embodiment provides, after focus adjustment is good, main cylinder 2 be fixedly by regulating the inner of driving lever 6 to offset to realize with the outer wall of main 2, therefore, compare with the mode of the fixing main cylinder 02 of prior art indirect, in the camera lens that the utility model provides, the fixed form of main cylinder 2 has improved the stability after main cylinder 2 is fixed, thereby can prevent from causing main cylinder 2 to move when vibration occurs video camera, and then be conducive to reduce the probability that video camera imaging fuzzy problem occurs.
Please refer to Fig. 3 and Fig. 5, in a kind of preferably execution mode, screwed hole 51 on above-mentioned adjustable ring 5 is along the radially extension of main body tube 4, to guarantee regulating driving lever 6 to be installed on after screwed hole 51 by threaded engagement, regulate driving lever 6 to screw and offset with the outer wall of main cylinder 2, the force direction that the inner that regulates driving lever 6 applies to the outer wall of main cylinder 2 points to the axle center of main cylinder 2, has improved the stability after regulating driving lever 6 that main cylinder 2 is fixing.
At some, alternatively in execution mode, the inner of above-mentioned adjusting driving lever 6 is pyramidal structure.Like this, regulate the inner of driving lever 6 and the outer wall of main cylinder 2 to offset, being the tip of pyramidal structure and the outer wall of main 2 offsets, reduced to regulate the contact area between the inner of driving lever 6 and the outer wall of main cylinder 2, increased the pressure that regulates 6 pairs of main cylinder 2 outer wall application point places of driving lever, thereby can prevent from regulating the inner of driving lever 6 to slide on the outer wall of main cylinder 2, further improve the stability after regulating driving lever 6 that main cylinder 2 is fixing.
Please refer to Fig. 4 and Fig. 5, above-mentioned adjustable ring 5 is slidably connected and is specially with main cylinder 2:
Main body tube 4 is provided with at least one second chute 42 extending along its direction of axis line;
Adjustable ring 5 is provided with and the second chute 42 helicla flute 52 one to one;
Main cylinder 2 has the guide pin that passes the second chute 42 and helicla flute 52 and be slidably matched with the second chute 42 and helicla flute 52 simultaneously.
When adjustable ring 5 rotates, on adjustable ring 5, between helicla flute 52 and guide pin, there is relative sliding, make the inwall of helicla flute 52 can promote guide pin along the second chute 42 slips on main body tube 4, thereby main cylinder 2 direction of axis line along main body tube 4 are moved, to regulate the distance between image inductor in main cylinder 2 interior set of lenses 1 and video camera.And guide pin is arranged in the second chute 42, the second chute 42 can limit the rotation of main cylinder 2 in main body tube 4; Guide pin is arranged in helicla flute 52, and helicla flute 52 can limit main cylinder 2 and move at the interior axial line along main body tube 4 of main body tube 4, and after guaranteeing regulating the inner of driving lever 6 and the outer wall of main cylinder 2 to offset, main cylinder 2 can not be moved again.
In the respective embodiments described above, main body tube 4 is connected being fixedly connected with realization body pipe 4 and shell 3 with shell 3 by screw 31.More preferably, as shown in Figure 3 and Figure 6, the shell 3 of camera lens also covers in outside adjustable ring 5, and shell 3 position relative with screwed hole 51 has the 3rd chute 32 of dodging adjusting driving lever 6, make the surface of camera lens more level and smooth, improved the aesthetic feeling of camera lens integral body.
Embodiment bis-
A kind of video camera that the present embodiment two provides, it comprises image inductor, also comprises the camera lens that above-described embodiment one provides, image inductor is positioned at the picture side of camera lens.
In the video camera providing due to above-described embodiment one, after the focus adjustment of video camera is good, main cylinder be fixedly by regulating the inner of driving lever to offset to realize with the outer wall of main, improved the stability after main cylinder is fixed, thereby can prevent from causing main cylinder mobile when vibration occurs video camera, be conducive to reduce the probability that video camera imaging fuzzy problem occurs.Therefore, in use, the stability after the interior main cylinder of video camera is fixing is higher, is difficult for being moved because of the vibration of video camera, is conducive to improve the imaging effect of video camera for the video camera that the present embodiment provides.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
