It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation of the present utility model. In addition, "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium; it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] As Figures 1 to 4 shown, an embodiment of the present utility model provides a projection lens detection jig, which includes a frame body 10, a substrate 20 arranged on the frame body 10, and a lens placement module 30, a lens jig 40, and a lens pressing module 50 longitudinally arranged on the substrate 20 in sequence; the lens jig 40 is placed on the lens placement module 30, and the lens pressing module 50 is arranged on the side of the lens jig 40 away from the lens placement module 30. Specifically, the lens jig 40 includes a front lens barrel 41 and a rear lens barrel 42 sleeved on one end of the front lens barrel 41. An adjustment needle 43 is arranged at the other end of the front lens barrel 41. After the rear lens barrel 42 is sleeved on the front lens barrel 41, a lens can be installed in the front lens barrel 41 and the rear lens barrel 42, which are divided into an imaging part and a light collimation part. By rotating the adjustment needle 43, the angle of the front lens barrel 41 can be adjusted, and then the angle of the projection lens can be adjusted, so as to quickly complete the detection of the imaging quality of the projection lens at different angles.

[0030] As Figures 2 to 4 shown, in this example, the lens placement module 30 includes a lens hole plate 31 and a bearing base 32. The bearing base 32 is arranged between the lens hole plate 31 and the lens pressing module 50, and the lens jig 40 is placed on the bearing base 32.

[0031] In this example, a placement groove 321 and a limiting platform 323 are arranged on the bearing base 32. A plurality of limiting grooves 322 are arranged in the placement groove 321. Limiting posts 421 matching the plurality of limiting grooves 322 are arranged on the outer wall of the rear lens barrel 42, and a limiting wall 422 cooperating with the limiting platform 323 is arranged on the outer wall of the rear lens barrel 42. The limiting posts 421 are clamped in the limiting grooves 322 so that the rear lens barrel 42 is fixedly placed in the placement groove 321, and the limiting wall 422 is arranged on the limiting platform 323 to further fix the rear lens barrel 42. Thus, when the angle of the front lens barrel 41 is adjusted by rotating the adjustment needle 43, the position of the rear lens barrel 42 remains fixed, that is, the adjustment needle 43 rotates the imaging part of the lens to adjust the angle of the projection image, so as to make the projection image completely parallel.

[0032] In this embodiment, a through lens placement hole 311 is provided on the lens aperture plate 31. A rubber washer is provided in the lens placement hole 311. The front lens barrel 41 abuts against the lens placement hole 311. Further, the front lens barrel 41 abuts against the rubber washer in the lens placement hole 311. When the lens pressing module 50 moves forward to press the lens fixture 40, the rubber washer can buffer the pressure and prevent the front lens barrel 41 from being damaged by extrusion.

[0033] As Figures 1 to 2 shown, in this embodiment, the lens pressing module 50 includes an adjustment assembly and two guiding assemblies connecting the adjustment assembly. The two guiding assemblies are respectively arranged on the left and right sides of the adjustment assembly to guide the adjustment assembly. The adjustment assembly includes a positioning plate 51, an adjustment rod 52, a rotating piece 53, an adjustment seat 54 and a handle 55. The positioning plate 51 is close to the lens placement module 30. One end of the adjustment rod 52 is connected to the positioning plate 51. One end of the rotating piece 53 is hinged to the other end of the adjustment rod 52. The other end of the rotating piece 53 is hinged to the handle 55. The handle 55 is hinged on the adjustment seat 54. A first sleeve 56 is installed on the adjustment seat 54. The adjustment rod 52 passes through the first sleeve 56 and is hinged to the rotating piece 53. In this embodiment, the inner wall of the first sleeve 56 is in contact with the side wall of the guiding rod 59, so that the first sleeve 56 can slide relative to the adjustment rod 52. When the handle 55 is pressed down, the adjustment rod 52 moves forward, driving the positioning plate 51 to move forward and approach the lens fixture 40, and then pressing and fixing the lens fixture 40 on the lens placement module 30.

[0034] Specifically, both guiding assemblies include a second sleeve 57 arranged on the positioning plate 51, fixing blocks 58 arranged on both sides of the second sleeve 57 along the direction of the adjustment rod 52, and a guiding rod 59 passing through the second sleeve 57 and connected to the fixing blocks 58.

[0035] In this embodiment, an image light source 510 is provided on the side of the positioning plate 51 facing the lens fixture 40. A heat dissipation plate 511 is also provided between the image light source 510 and the positioning plate 51. The image light source 510 provides a light source image, and the heat dissipation plate 511 dissipates heat from the image light source 510.

[0036] The above only expresses the preferred technical solutions of the present invention, and its description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and the present invention also intends to include these changes and modifications.
