Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, and more specifically to a lens barrel angle adjustment device and an optical lens. Background Art

[0002] In the internal structure of the optical lens, the front cylindrical lens is fixed on the front lens barrel, and the rear cylindrical lens is fixed on the rear lens barrel. Due to the optical design, the relative angle of the two cylindrical lenses is relatively sensitive and will affect the shape of the light spot, so the relative angle of the two lens barrels needs to be debugged. The traditional debugging is to adjust to the appropriate angle and directly tighten the screws on the side wall of the lens barrel. However, since the matching clearance between the two lens barrels will change during the process of screwing the lens barrel, the relative angle of the two cylindrical lenses will change, causing the light spot to change, affecting the production yield of the optical lens.

The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0041] like Figure 1 and Figure 2 As shown, a lens barrel angle adjustment device 100 provided by an embodiment of the utility model is used for adjusting the relative angle of lens barrels in an optical lens, maintaining the stability of the angle between two relative lens barrels in the optical lens, so that the relative angle of lenses in the lens barrels is fixed, and the possibility of light spot change is reduced; for example, the optical lens of this embodiment includes two lens barrels, one of which is a front lens barrel 200, and a front cylindrical lens 201 is fixed on the front lens barrel 200, and the other lens barrel is a rear lens barrel 300, and a rear cylindrical lens 301 is fixed on the rear lens barrel 300, and the front lens barrel 200 and the rear lens barrel 300 are connected, so that the front cylindrical lens 201 is opposite to the rear cylindrical lens 301; the lens barrel angle adjustment device 100 can maintain the relative angle between the front lens barrel 200 and the rear lens barrel 300, so that the two lens barrels still maintain the current relative angle when they are fastened, and reduce the relative angle between the two lenses caused by the fastening connection Changes, thereby causing light spot changes; the following is an explanation through specific implementation methods:

[0042] like Figure 3 and Figure 4 As shown, the lens barrel angle adjustment device 100 of this embodiment includes: a clamp assembly 1 and a connecting assembly 2;

[0043] The hoop assembly 1 includes a first hoop unit 11 and a second hoop unit 12, the first hoop unit 11 and the second hoop unit 12 are detachably connected, and the first hoop unit 11 and the second hoop unit 12 are connected to form a fixed space for fixing two adjacent lens barrels in the optical lens; at least one of the first hoop unit 11 and the second hoop unit 12 is provided with an opening 13 corresponding to the screw hole 202 on the lens barrel;

[0044] Here, it can be understood that the hoop assembly 1 refers to a component used to wrap and fix on the connecting part of the two lens barrels; the hoop assembly 1 includes a first hoop unit 11 and a second hoop unit 12; wherein the first hoop unit 11 refers to one of the units of the hoop assembly 1, and the second hoop unit 12 refers to another unit of the hoop assembly 1; the first hoop unit 11 and the second hoop unit 12 are detachably connected, that is, the first hoop unit 11 and the second hoop unit 12 can be wrapped and fixed on the connecting part of the two lens barrels, and can also be removed from the connecting part; the first hoop unit 11 and the second hoop unit 12 can enclose to form a fixed space when connected to each other, and the connecting part of the two lens barrels can be placed in the fixed space, so that the first hoop unit 11 and the second hoop unit 12 wrap the fixed connecting part; at least one of the first hoop unit 11 and the second hoop unit 12 is provided with an opening 13, and the opening 13 corresponds to the screw hole 202 on the lens barrel, so that the assembler can fasten the screw hole 202 through the opening 13 using a fastener 203 (such as a screw);

[0045] The connecting assembly 2 is used for detachably connecting the first clamp unit 11 and the second clamp unit 12 .

[0046] Here, it can be understood that the connecting component 2 refers to a component used to connect the clamp assembly 1; wherein the connecting component 2 is used to detachably connect the first clamp unit 11 and the second clamp unit 12 to achieve installation and disassembly of the clamp assembly 1.

[0047] The working principle of the lens barrel angle adjustment device 100 provided in this embodiment is as follows:

[0048] The two lens barrels need to be screwed together, the connection between the first hoop unit 11 and the second hoop unit 12 is released, and the hoop is wrapped around the connecting part of the two lens barrels, the opening 13 is aligned with the screw hole 202 of the lens barrel, and then the connection assembly 2 is connected to the first hoop unit 11 and the second hoop unit 12, so that the first hoop unit 11 and the second hoop unit 12 are wrapped and fixed on the connecting part of the two lens barrels under the connecting force of the connection assembly 2, and then the screw hole 202 is tightened in the opening 13 to make the two lens barrels tightly connected. Before adjusting the relative angle of the two lens barrels, use the hoop assembly 1 to pre-fix, when the relative angle of the two lens barrels is adjusted to the appropriate position, lock the hoop, and then lock the side screws of the lens barrel, and finally remove the hoop, the light spot generated by the lens of the lens barrel remains unchanged.

[0049] By adopting the above technical solution, the clamp assembly 1 can wrap and fix the connecting part of the two lens barrels, pre-fix the relative angle of the two lens barrels, and lock the clamp when the relative angle of the two lens barrels is adjusted to a suitable position, thereby reducing the relative angular movement or rotation of the two lens barrels, so that the light spot generated by the lens remains unchanged after the screws tighten the two lens barrels, thereby improving the product production yield.

[0050] In one embodiment, when the first clamp unit 11 is provided with an opening 13 , a plurality of openings 13 are sequentially and spaced apart in the circumferential direction of the first clamp unit 11 .

[0051] Here, it can be understood that, since the lens barrel is provided with a plurality of screw holes 202 along its circumference, the openings 13 of the first clamping hoop unit 11 are provided corresponding to the screw holes 202 of the lens barrel, and the plurality of openings 13 are arranged on the circumference of the first clamping hoop unit 11 .

[0052] By adopting the above technical solution, the openings 13 on the first clamping hoop unit 11 correspond to the screw holes 202 of the lens barrel one by one, which facilitates the assembly personnel to perform screw tightening operations on the lens barrel.

[0053] In one embodiment, when the second clamp unit 12 is provided with an opening 13 , a plurality of openings 13 are sequentially and spaced apart in the circumferential direction of the second clamp unit 12 .

[0054] Here, it can be understood that, since the lens barrel is provided with a plurality of screw holes 202 along its circumference, the openings 13 of the second clamping hoop unit 12 are provided corresponding to the screw holes 202 of the lens barrel, and the plurality of openings 13 are arranged on the circumference of the second clamping hoop unit 12 .

[0055] By adopting the above technical solution, the openings 13 on the second clamping hoop unit 12 correspond one-to-one with the screw holes 202 of the lens barrel, which facilitates the assembly personnel to perform screw tightening operations on the lens barrel.

[0056] In one embodiment, the diameter of the opening 13 is larger than the diameter of the screw hole 202 .

[0057] Here, it can be understood that, when assembling the clamp assembly 1, in order to reduce the possibility of misalignment between the opening 13 and the screw hole 202, the aperture of the opening 13 is set to be larger than the aperture of the screw hole 202. When the clamp assembly 1 is offset in the circumferential or axial direction, due to the larger aperture of the opening 13, the screw hole 202 is still in the opening 13, and the assembler can still tighten the screw in the screw hole 202.

[0058] It needs to be further explained that the aperture of the opening 13 is larger than the aperture of the screw hole 202 , which enlarges the operating space of the screw and facilitates the assembler to tighten the screw in the screw hole 202 .

[0059] By adopting the above technical solution, the possibility of misalignment between the opening 13 and the threaded hole is reduced, the operating space of the screw is expanded, and the operation of the assembler is facilitated.

[0060] In one embodiment, the opening 13 is a square opening 13 .

[0061] Here, it can be understood that the circumferential and axial dimensions of the opening 13 of the clamp assembly 1 are larger than the circumferential and axial dimensions of the screw hole 202 of the clamp assembly 1. Even if the clamp assembly 1 is slightly displaced circumferentially relative to the lens barrel, or slightly displaced axially relative to the lens barrel, the opening 13 can still expose the screw hole 202, reducing the possibility of misalignment between the two.

[0062] By adopting the above technical solution, the possibility of misalignment between the opening 13 and the threaded hole is reduced.

[0063] In one embodiment, the connecting assembly 2 includes a plurality of connecting members 21 ; first connecting ears 111 are respectively provided at both ends of the first clamp unit 11 ; second connecting ears 121 are respectively provided at both ends of the second clamp unit 12 ; a connecting member 21 is connected between the first connecting ear 111 and the second connecting ear 121 .

[0064] Here, it can be understood that the connecting member 21 includes but is not limited to screws, by which the first clamp unit 11 and the second clamp unit 12 are fastened and connected, wherein the first clamp unit 11 is provided with a first connecting ear 111 at both ends, and the second clamp unit 12 is provided with a second connecting ear 121 at both ends, and the first connecting ear 111 and the second connecting ear 121 are connected correspondingly, and the two are connected by the connecting member 21.

[0065] By adopting the above technical solution, the detachable connection between the first clamp unit 11 and the second clamp unit 12 is achieved.

[0066] In one embodiment, the first connecting ear 111 and the second connecting ear 121 are arranged to protrude away from the fixing space.

[0067] Here, it can be understood that in order to reduce the influence of the first connecting ear 111 and the second connecting ear 121 on the fixing space, the first connecting ear 111 and the second connecting ear 121 are arranged to protrude away from the fixing space.

[0068] By adopting the above technical solution, the influence of the first connecting ear 111 and the second connecting ear 121 on the fixing space is reduced, and at the same time, the protruding first connecting ear 111 and the second connecting ear 121 also facilitate the assembly personnel to perform the fastening operation.

[0069] In one embodiment, a plurality of first connecting holes 112 are provided on the first connecting ear 111 along the axial direction of the clamp assembly 1, and a plurality of second connecting holes 122 are provided on the second connecting ear 121 along the axial direction of the clamp assembly 1. The first connecting holes 112 correspond to the second connecting holes 122 one by one, and the connecting member 21 is passed through the first connecting holes 112 and the second connecting holes 122.

[0070] Here, it can be understood that the first connecting ear 111 is provided with a plurality of first connecting holes 112, and the plurality of first connecting holes 112 are arranged along the axial direction of the clamp assembly 1, thereby improving the axial stability of the clamp assembly 1 when it is fixed; similarly, the second connecting ear 121 is provided with a plurality of second connecting holes 122, and the plurality of second connecting holes 122 are arranged along the axial direction of the clamp assembly 1, thereby improving the axial stability of the clamp assembly 1 when it is fixed.

[0071] By adopting the above technical solution, the stability of the clamp assembly 1 during fixation is improved.

[0072] In one embodiment, the first clamp unit 11 and the second clamp unit 12 are both semicircular clamp units.

[0073] Here, it can be understood that the shape of the lens barrel is cylindrical. In order to increase the contact area between the clamp assembly 1 and the lens barrel and the stability when fixed, the first clamp unit 11 and the second clamp unit 12 are set as semicircular clamp units. In this way, when the first clamp unit 11 and the second clamp unit 12 are enclosed, a circular clamp assembly 1 can be formed, so that the contact area between the clamp assembly 1 and the lens barrel is increased when the clamp fixes the connecting part of the lens barrel, thereby improving the stability when fixed.

[0074] By adopting the above technical solution, the matching degree between the clamp assembly 1 and the lens barrel is improved, thereby improving the stability of the clamp assembly 1 when wrapping and fixing the lens barrel.

[0075] In a second aspect, an optical lens is provided, including two lens barrels and the above-mentioned lens barrel angle adjustment device 100, wherein lenses are arranged in the lens barrels, and a clamp assembly 1 is used to fix the two lens barrels.

[0076] By adopting the above technical solution, on the basis of having the advantages of the lens barrel angle adjustment device 100 of the above embodiment, the optical lens of this embodiment also has the advantage of high relative angle accuracy of the lens.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
