As shown in fig. 1 and fig. 2, in a specific embodiment of the present invention, the focal length locking structure 203 includes a focal length locking screw 2031 and a focal length locking nut 2032 fixed to the bracket 2, the focal length locking screw 2031 is in threaded engagement with the focal length locking nut 2032, and after the focal length adjustment rod 201 completes the focal length adjustment, the focal length locking screw 2031 rotates along the focal length locking nut 2032 and pushes the focal length adjustment ring 102 to be fixed to the housing 106 of the lens 101.
Since the rotation of the focus adjustment ring 102 is restricted when the focus adjustment ring 102 abuts against the housing 106 of the lens 101, by setting the focus locking structure 203 to be fixed to the focus locking nut 2032 of the bracket 2 and the focus locking screw 2031 in threaded engagement with the focus locking nut 2032, it is possible to press the focus adjustment ring 102 against the housing 106 of the lens 101 by rotating the focus locking screw 2031, thereby conveniently fixing the focus adjustment ring 102.
The fixing manner of the focal length locking nut 2032 and the bracket 2 is not limited, and the focal length locking nut 2032 can be fixed on the bracket 2 by hot melting or in-mold injection molding.

The structure of the camera can be more compact by inserting the focal length locking screw 2031 into the first mounting hole of the focal length adjusting rod 201 and rotatably connecting the focal length locking screw 2031 with the focal length adjusting rod 201. Furthermore, anti-slip structures such as rubber can be arranged at the connection position of the focal length adjusting rod 201 and the bracket 2, so that a larger damping is provided between the focal length adjusting rod 201 and the bracket 2, and thus, when the focal length locking screw 2031 is rotated, the focal length adjusting rod 201 can be effectively prevented from shaking.
Referring to fig. 2, in an alternative embodiment of the present invention, similar to the manner of the focal length locking structure 203, the zooming locking structure 204 includes a zooming locking screw 2041 and a zooming locking nut 2042 fixed to the bracket 2, the zooming locking screw 2041 is in threaded engagement with the zooming locking nut 2042, after the zooming adjustment of the zooming adjustment rod 202 is completed, the zooming locking screw 2041 rotates along the zooming locking nut 2042, and pushes the zooming adjustment ring 103 to abut against the housing 106 of the lens 101.
The zooming locking structure 204 is arranged to be fixed on the zooming locking nut 2042 of the bracket 2 and the zooming locking screw 2041 in threaded fit with the zooming locking nut 2042, so that the zooming adjusting ring 103 can be abutted against the shell 106 of the lens 101 by rotating the zooming locking screw 2040, and the zooming adjusting ring 103 can be fixed conveniently.
As shown in fig. 2, in any embodiment of the present invention, optionally, the zoom locking screw 2041 is coaxially disposed with the zoom adjusting lever, the zoom adjusting lever 202 has a second mounting hole, and the zoom locking screw 2041 penetrates through the second mounting hole and is rotatably connected with the zoom adjusting lever 202.
The zoom locking screw 2041 penetrates through the second mounting hole of the zoom adjusting rod 202, and the zoom locking screw 2041 is rotatably connected with the zoom adjusting rod 202, so that the structure of the camera is more compact. Furthermore, the connecting portion between the zoom adjusting rod 202 and the bracket 2 may be provided with an anti-slip structure such as rubber, so that a larger damping force is provided between the zoom adjusting rod 202 and the bracket 2, and thus, when the zoom locking screw 2041 is rotated, the shake of the zoom adjusting rod 202 can be effectively avoided.
As shown in fig. 1 and fig. 2, in the embodiment of the present invention, optionally, the bracket 2 is sleeved on the lens 101 and is fixedly connected to the housing 106 of the lens 101.
Because when the focal length locking screw 2031 and the zoom locking screw 2041 respectively push the focal length adjusting ring 102 and the zoom adjusting ring 103, a certain thrust force is inevitably generated on the lens 101, and because of the existence of the thrust force, the structural member of the lens 101 is likely to generate strain, thereby affecting the image imaging effect. Through the bracket 2 is sleeved on the lens 101 and fixedly connected with the shell 106 of the lens 101, the thrust caused by the locking of the focal length locking screw 2031 and the zoom locking screw 2041 becomes the internal force between the lens 101 and the bracket 2, thereby greatly reducing the influence on the image imaging effect.
As shown in fig. 1, the lens movement assembly further includes a lens fixing plate 5 and a lens holder 4, and the lens 101 is fixed to the lens fixing plate 5 through the lens holder 4.
In one particular embodiment of the invention, as shown in fig. 1 and 2, the camera is assembled as follows: first, the zoom adjusting structure 105 is directly fitted over the zoom adjusting ring 103 of the lens 101 and fixed relatively thereto by the screw 3. Secondly, the zooming locking nut 2042 and the focus locking nut 2032 are fixed to corresponding positions of the bracket 2 by means of hot melting or in-mold injection respectively, the zooming adjusting rod 202 and the focus adjusting rod 201 are arranged in corresponding hole positions of the bracket 2 in a penetrating manner, and the zooming adjusting rod 202 and the focus adjusting rod 201 can rotate relative to the bracket 2 respectively. Then, the focal length locking screw 2031 and the zoom locking screw 2041 are respectively and correspondingly inserted into the focal length adjusting rod 201 and the zoom adjusting rod 202, the focal length locking screw 2031 is screwed into the focal length locking nut 2032, and the zoom locking screw 2041 is screwed into the zoom locking nut 2042; the assembled bracket 2 is then sleeved to the corresponding position of the lens 101 from bottom to top and is fixed with the shell 106 of the lens 101 through the screw 3. Then, the focus adjusting structure 104 is sleeved on the corresponding position of the lens 101, and the relative fixation between the two is realized by the screw 3. Finally, the lens mount 4 and the lens fixing plate 5 are sequentially mounted on the corresponding positions of the lens 101 to complete the mounting of the camera.
After the installation of the camera is completed, if the zoom adjusting rod 202 is rotated, the zoom adjusting structure 105 can be driven to rotate through the transmission of the bevel gear, and then the zoom adjusting ring 103 of the lens 101 is driven to rotate, so that the up-and-down movement of the lens 1011 connected with the zoom adjusting ring 103, namely the zoom action, is realized; similarly, if the focal length adjustment rod 201 is rotated, the bevel gear drives the focal length adjustment structure 104 to rotate, and further drives the focal length adjustment ring 102 of the lens 101 to rotate, so as to achieve the focusing action.
When the adjustment of the focus adjustment lever 201 and the zoom adjustment lever 202 is completed, in order to keep the image at a clear position all the time and to avoid blurring of the image due to unnecessary shaking, the zoom adjustment ring 103 and the focus adjustment ring 102 of the lens 101 need to be locked. At this time, the focus locking screw 2031 coaxial with the focus adjustment lever 201 and the zoom locking screw 2041 coaxial with the zoom adjustment lever 202 may be rotated by a tool, respectively. Because the zoom locking screw 2041 and the zoom adjusting rod 202 can rotate relatively and a certain damping is designed between the zoom adjusting rod 202 and the bracket 2, the adjustment of the zoom locking screw 2041 does not drive the zoom adjusting rod 202 to shake. The rotation of the variable-magnification locking screw 2041 causes the variable-magnification locking screw to be tightly locked with the variable-magnification locking nut 2042 through thread matching. Similarly, the rotation of the focus lock screw 2031 can lock the focus adjustment ring 102.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
