Detailed Description
Front and rear lens holder connection assembly embodiments
Referring to fig. 1 to 4, the front and rear lens seat connecting assembly provided by the embodiment includes a front lens seat 1, a rear lens seat 2 and four connecting pieces 3, the front lens seat 1 and the rear lens seat 2 are detachably connected through the connecting pieces 3, and the front lens seat 1 and the rear lens seat 2 can be easily detached only by unscrewing the connecting pieces 3 during repair or after-sale maintenance in the production process. A front mounting hole is arranged in the front lens seat 1 along the self axial direction, a rear mounting hole is arranged in the rear lens seat 2 along the self axial direction, and the front mounting hole and the rear mounting hole are coaxially arranged and are communicated with each other. The front mounting hole and the rear mounting hole are used for mounting the lens.
The one end outside of preceding lens seat 1 is provided with preceding annular flange 11 and four preceding bellying 12, and preceding annular flange 11 outwards extends along its self circumference from the periphery wall of preceding lens seat 1, and four preceding bellying 12 are evenly arranged on the periphery wall of preceding lens seat 1 along the circumference interval of preceding lens seat 1, are formed with the breach between two adjacent preceding bellying 12. The front annular flange 11 and the front projection 12 are arranged in line in the axial direction of the front lens holder 1, and the front projection 12 is located on the side close to the end of the front lens holder 1. The front annular flange 11 and the front protrusion 12 are spaced apart by a predetermined distance in the axial direction of the front lens holder 1.
The inside of the rear lens holder 2 is provided with a rear annular flange 21 and four rear bosses 22. A rear annular flange 21 is located in the axial middle of the rear lens mount 2, the rear annular flange 21 extending from the inner peripheral wall of the rear lens mount 2 toward the center in its own circumferential direction. The rear convex part 22 is located at one end of the rear lens seat 2 facing the front lens seat 1, the four rear convex parts 22 are uniformly arranged along the circumferential direction of the rear lens seat 2 at intervals, and the rear convex part 22 and the rear annular flange 21 are arranged along the axial direction of the rear lens seat 2. An inlet and an outlet 23 are formed between two adjacent rear bosses 22, an installation groove 24 is formed between the rear bosses 22 and the rear annular flange 21, and the installation groove 24 is communicated with the inlet and the outlet 23. In the circumferential direction of the rear lens holder 2, the mounting groove 24 and the inlet/outlet 23 are arranged in a staggered manner, that is, the inlet/outlet 23 is located on one side in the circumferential direction of the rear boss 22, and the mounting groove 24 is located on the rear side in the axial direction of the rear boss 22. The front convex portion 12 of the front lens holder 1 is disposed in the mounting groove 24 through the access opening 23, and at this time, the rear convex portion 22 is located between the front annular flange 11 and the front convex portion 12, and the front convex portion 12 is located between the rear convex portion 22 and the rear annular flange 21, so that the front lens holder 1 and the rear lens holder 2 cannot be separated in the axial direction. When the front convex part 12 and the rear convex part 22 are opposite along the axial direction, the matching between the front lens seat 1 and the rear lens seat 2 meets the requirement of radial angle position, and the assembling and adjusting device has the advantages of convenience and high efficiency.
In fig. 4, when the front lens holder 1 and the rear lens holder 2 are coupled, the front projection 12 is located in the mounting groove 24, and the rear projection 22 is located between the front projection 12 and the front annular flange 11. In order to prevent the front lens holder 1 and the rear lens holder 2 from moving relatively, the rear lens holder 2 is further provided with four connecting holes 25. The connecting hole 25 extends to the mounting groove 24 from the peripheral wall of the rear lens seat 2, the connecting piece 3 is a conical head screw, the connecting hole 25 is a threaded hole, and the connecting piece 3 penetrates through the connecting hole 25 to be connected in the mounting groove 24. The connecting piece 3 is positioned between the front convex part 12 and the rear convex part 22, and the connecting piece 3 is respectively connected with the front convex part 12 and the rear convex part 22. The connecting piece 3 forces the side surface of the front convex part 12 to slightly dent, so as to achieve the radial locking effect. Meanwhile, the connecting piece 3 is extruded towards two sides, so that the front annular flange 11 is tightly attached to the rear protruding portion 22, the front protruding portion 12 is tightly attached to the rear annular flange 22, the front lens seat 1 and the rear lens seat 2 use the fixing surface as a force transmission surface, the force transmission surface with a fastening piece (such as a screw) in the prior art is replaced, and the improvement on the connection stability and the impact resistance of the front lens seat 1 and the rear lens seat 2 is facilitated. At this time, the cooperation between the front lens mount 1 and the rear lens mount 2 satisfies the requirement of the axial position. The connecting piece 3 can limit the relative movement of the front lens seat 1 and the back lens seat 2. The relative movement of the present embodiment includes wobbling in the axial direction and rotation in the circumferential direction.
Specifically, the side of the front protrusion 12 facing away from the end surface of the front lens holder 1 closest to one end is provided with a first inclined surface 121, and the first inclined surface 121 extends obliquely in the radial direction of the front lens holder 1 towards the end of the front lens holder 1 closest to the one end. The end of the connecting piece 3 is provided with a second inclined surface 31, and the second inclined surface 31 extends obliquely toward the center of the connecting piece 3 in the axial direction of the connecting piece 3. The first inclined surface 121 and the second inclined surface 31 are inclined in the same direction. In the axial direction of the front lens holder 1, the axial inclination angle of the first inclined plane 121 and the front lens holder 1 is greater than the axial inclination angle of the second inclined plane 31 and the front lens holder 1, so as to ensure that the first inclined plane 121 and the second inclined plane 31 contact with each other to the maximum extent, and prevent the connecting member 3 from loosening after being mounted for many times.
In other embodiments, the number of the front convex portions 12 and the number of the rear convex portions 22 may also be two, three or more, wherein the number of the front convex portions 12 is equal to the number of the rear convex portions 22 and the front convex portions are arranged in a one-to-one correspondence. The number of the coupling holes 25 and the coupling members 3 is arranged in one-to-one correspondence to the number of the mounting grooves 24. When the connecting member 3 is installed, the surface of the connecting member 3 may be coated with no adhesive (such as glue) or may be coated with an adhesive. When the adhesive is not coated, the connecting piece 3 can be disassembled only by unscrewing, so that the disassembling operation of production repair or after-sale maintenance is facilitated, and meanwhile, the damage to adjacent parts caused by high-temperature baking is avoided; even if the adhesive is coated, because the connecting piece 3 is small in size, the coating area of the adhesive is correspondingly small, and the difficulty in disassembling the connecting piece 3 is smaller than that in the prior art.
