Referring to fig. 3 to 5, in the present embodiment, preferably, a first limiting portion 6 is further provided between the fastening ring 5 and the locking ring 2 to prevent the elastic member 4 from being excessively compressed and not rebounded to generate elastic force when the frame 1 is locked. In this embodiment, the first limiting portion 6 is preferably annular and is integrally formed with the fastening ring 5. In other embodiments, the first limiting portion 6 may also have a bump shape, and a plurality of bumps are uniformly connected to the fastening ring 5 to limit the movement of the fastening ring 5 relative to the locking ring 2 so as to prevent the wave spring from being excessively compressed.
Referring to fig. 3 to 5, in the present embodiment, an annular wall 21 is formed on the locking ring 2 extending toward the end of the frame 1, such that an annular groove 7 is formed between the locking ring 2 and the threaded portion 11, the elastic member 4 and the fastening ring 5 can be installed in the annular groove 7, and a second limiting portion 8 is detachably connected to the annular wall 21 to prevent the fastening ring 5 from being ejected out of the annular groove 7 by the elastic member 4.
Referring to fig. 1, in the embodiment, the second limiting portion 8 is a notched snap ring, the annular wall 21 is provided with a snap ring mounting groove 211, the snap ring is detachably mounted in the snap ring mounting groove 211, the fastening ring 5 is provided with a limiting protrusion 51 matched with the snap ring, and the snap ring is matched with the limiting protrusion 51 to prevent the fastening ring 5 from being ejected out of the annular groove 7 by the elastic member 4.
Referring to fig. 1, in this embodiment, preferably, a corrugated portion for facilitating rotation of the lens frame 1 is provided on the outer periphery of the lens frame 1, and a corrugated portion for facilitating rotation of the locking ring is also provided on the outer periphery of the locking ring 2.
Referring to fig. 1 and 2, when assembling, the locking ring 2 is first screwed onto the threaded portion 11 at the end of the lens frame 1, such that an annular groove 7 is formed between the annular wall 21 and the threaded portion 11 on the locking ring 2, then the elastic member 4 (wave spring) is sleeved into the annular groove 7, then the fastening ring 5 is correspondingly sleeved, then the fastening ring 5 is pressed inward, and the second limiting portion 8 (snap ring) is clamped into the snap ring mounting groove 211 on the annular wall 21 to limit the fastening ring 5, so as to prevent the fastening ring 5 from being ejected out of the annular groove 7 by the wave spring.
Referring to fig. 3 to 5, when in use, the camera connecting ring 3 at the end of the lens frame 1 is connected together by the threads of the threaded portion 11, the lens frame 1 is rotated to move axially relative to the camera connecting ring 3 for focusing, after focusing is completed, the lens frame 1 and the camera connecting ring 3 are kept stationary, the lock ring 2 is rotated to drive the fastening ring 5 to approach the camera connecting ring 3 until one end of the fastening ring 5 abuts against the camera connecting ring 3, the other end of the fastening ring 5 abuts against the lock ring 2 through the first limiting portion 6, at this time, the elastic member 4 (wave spring) is compressed, but due to the limiting effect of the first limiting portion 6, the wave spring is not excessively compressed and cannot rebound to generate elastic force, at this time, the lock ring 2 is rigidly contacted with the camera connecting ring 3 through the first limiting portion 6 and the fastening ring 5 (as shown in fig. 6), and a mutual acting force in opposite directions is generated at the threaded connection position of the lens frame 1 and the camera connecting ring 3 to lock the lens frame 1 and keep the relative position of the lens frame 1 and the camera connecting ring 3 unchanged. When the focal length needs to be changed, the lock ring 2 can be unscrewed first, then the lens frame 1 is rotated for focusing, and after focusing is finished, the lock ring 2 is rotated again to lock the lens frame 1, so that refocusing is finished. However, when the lock ring 2 is rotated, the lens frame 1 may be slightly rotated to change the focal length when the lens frame 1 is locked, at this time, the relative position of the lens frame 1 with respect to the camera connector 3 may be finely adjusted to a proper focal length by forcibly rotating the lens frame 1, and when the lens frame 1 is finely adjusted and forcibly rotated to move the lens frame 1 with respect to the camera connector 3, the lock ring 2 still keeps rigid contact with the camera connector 3 through the fastening ring 5, thereby locking the lens frame 1; when the fine tuning mirror frame 1 makes the mirror frame 1 move outwards relative to the camera connecting ring 3, the mirror frame 1 drives the lock ring 2 to move outwards relative to the camera connecting ring 3 together, but due to the elastic force of the wave spring, the lock ring 2 is changed into elastic contact with the camera connecting ring 3 through the rigid contact of the fastening ring 5 and the first limiting part 6 (as shown in fig. 5), at the moment, the first limiting part 6 is not propped against the lock ring 2, but the fastening ring 5 is pushed by the wave spring to elastically prop against the camera connecting ring 3, at the moment, an interaction force with opposite directions still exists at the threaded connection position of the mirror frame 1 and the camera connecting ring 3 to fasten the mirror frame 1 and keep the relative positions of the mirror frame 1 and the camera connecting ring 3 unchanged, so that the focus losing function is not easy to loose and focus losing is realized; the provision of a wave spring between the locking ring 2 and the fastening ring 5 thus allows the locking ring 2 to have the effect of fastening the frame 1 in the event of a rigid or elastic contact of the fastening ring 5 with the camera collar 3 in order to prevent the frame 1 from loosening out of focus. However, as the lens frame 1 moves outwardly relative to the camera collar 3, the compression of the wave spring is smaller, and the corresponding spring force is smaller, which results in a weaker fastening of the lens frame 1 by the locking ring 2, and thus this is suitable for a slight focusing. In addition, another refocusing mode is provided, after the first focusing is finished, when refocusing is needed, the lock ring 2 can be kept motionless relative to the camera connecting ring 3, the mirror frame 1 is directly forced to rotate for refocusing, no matter the mirror frame 1 is adjusted inwards or outwards relative to the camera connecting ring 3, the lock ring 2 is always kept in rigid contact with the camera connecting ring 3 through the fastening ring 5, and the function of locking the mirror frame 1 is achieved.
Referring to fig. 3 to 5, in the present embodiment, the threads of the locking ring 2 and the threaded portion 11 of the lens frame 1 are processed in an inter-fit manner, the shake management and control is within 0.02mm, the verticality of the end faces of the locking ring 2 and the camera connecting ring 3 is controlled within 0.01mm, the parallelism of the left and right end faces of the fastening ring 5 is controlled within 0.005 mm, and when in use, the locking ring 2 pushes the fastening ring 5 to be tightly pressed on the camera connecting ring 3, and the imaging stability of the lens can be ensured by the threaded fit of the components of the lens frame 1, the locking ring 2, the camera connecting ring 3, and the parallelism and verticality precision control of the components. And the elastic piece 4 is arranged between the lock ring 2 and the fastening ring 5, so that the anti-seismic performance of the lens is effectively improved.
Furthermore, it will be appreciated by those skilled in the art that other implementations are possible to lock the lens frame 1 and to keep the relative position of the lens frame 1 and the camera collar 3 unchanged in order to enable the lock ring 2 to bear against the camera collar 3 in a rigid or elastic contact by rotating the lock ring 2, for example, without providing the first limiting portion 6, compression of the wave spring may be limited directly by the annular wall 21 of the lock ring 2, and the lock ring 2 may be in rigid contact with the camera collar 3 by the annular wall 21. When the focusing is finished and the lens frame 1 is locked, the lock ring 2 is rotated to enable the lock ring 2 to be propped against the camera connecting ring 3 in a rigid contact manner, at the moment, the tail end of the annular wall 21 directly props against the camera connecting ring 3, and the wave spring is arranged in the annular groove 7, so that the situation that the wave spring is excessively compressed and cannot rebound to generate elasticity can be prevented; when the focal length is finely adjusted and the rigid contact between the locking ring 2 and the camera ring is changed into elastic contact, the locking ring 2 moves along with the lens frame 1 in a direction away from the camera ring 3, the annular wall 21 is not in contact with the camera ring 3, and the wave spring pushes the fastening ring 5 to elastically abut against the camera ring 3, so that an opposite interaction force is still generated at the threaded connection position of the lens frame 1 and the camera ring 3 to fasten the locking lens frame 1. It will be appreciated by those skilled in the art that the fastening of the frame 1 can also be achieved by the end of the wave spring directly abutting against the camera collar 3 resiliently, without the fastening ring 5.
Example two
The difference between the present embodiment and the first embodiment is that the first limiting portion 6 is annular and is integrally formed with the locking ring 2. In other embodiments, the first limiting portion 6 may also have a bump shape, and a plurality of bumps are uniformly connected to the locking ring 2 to limit the movement of the fastening ring 5 relative to the locking ring 2 so as to prevent the wave spring from being excessively compressed.
Example III
The difference between the first embodiment and the first embodiment is that the first limiting portion 6 is annular and slidably sleeved on the threaded portion 11 of the lens frame 1, and is located between the locking ring 2 and the fastening ring 5 to limit the movement of the fastening ring 5 relative to the locking ring 2 so as to prevent the wave spring from being excessively compressed.
The embodiments are merely illustrative of the technical solution of the present invention, and not limiting thereof; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the invention, and all other embodiments which may be obtained by those skilled in the art without making any inventive effort are therefore within the scope of the present invention.
