Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a 360-degree panoramic outer wall detection lens for large-viewing-field detection. Background Art

[0002] A lens refers to an optical component used by movie cameras and projectors to generate images. There is currently a panoramic lens for outer wall detection. In traditional machine vision solutions, to capture the outer wall information of an object, multiple cameras are required to capture one surface of the object respectively, and then the pictures are synthesized. Using a 360° panoramic lens, only one camera is needed to perfectly present the outer measurement of the object in one image, without the need for multiple cameras and multiple lenses, effectively simplifying the layout of the visual system and reducing costs; after long-term use, the lens is exposed to the air for a long time, and dust in the air will adhere to the lens surface, affecting the clarity of the image captured by the lens. It is necessary to manually use cleaning tools to clean the lens regularly, and the steps are relatively cumbersome and troublesome. In response to the above problems, the present application designs a 360-degree panoramic outer wall detection lens with a large field of view. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a panoramic outer wall detection lens for large field of view detection, comprising a lens barrel, a lens body being fixed to the bottom end of the lens barrel, a cleaning mechanism for cleaning the lens being arranged on the lens barrel, the cleaning mechanism comprising a lifting mechanism and a cleaning column, the cleaning column being fixed to the lens barrel through the lifting mechanism, the cleaning column being sleeved on the lens barrel, a first rotating groove being opened on the inner wall of the cleaning column near the bottom end, three rotating blocks being rotatably connected in the first rotating groove, a cleaning cotton block being fixed on the top of the rotating block, a rotating gear rail being fixed on the rotating block, an annular gear rail being slidably connected in the first rotating groove, the annular gear rail being meshed with the rotating gear rail, three slots being opened on the first rotating groove and communicating with the outer wall of the cleaning column, a connecting block being slidably connected to the slot, a rotating ring being fixed on the three connecting blocks, and the rotating ring being sleeved on the cleaning column.

[0007] Furthermore, the utility model is improved in that the lifting mechanism includes a fixed swivel, which is sleeved on the lens barrel and rotatably connected to the outer wall of the lens barrel, a spring is fixed to the bottom end of the fixed swivel, an annular fixing block is fixed to the other end of the spring, the annular fixing block is fixed to the inner wall of the cleaning column, and the annular fixing block is sleeved on the lens barrel.

[0008] In order to prevent slipping when the rotating ring is rotated, the utility model is improved in that anti-skid patterns are arranged on the outer wall of the rotating ring.

[0009] In order to prevent the cleaning column from getting stuck with the lens barrel when it is lifted or lowered, the utility model has an improvement in that one side of the rotating block close to the central axis of the cleaning column is provided with an arc surface with an arc, and the arc surface on the rotating block has the same arc as the inner wall of the cleaning column.

[0010] In order to make the rotating ring more stable when rotating, the utility model is improved in that a limiting sliding groove is arranged on the outer wall of the cleaning column, and a protrusion adapted to the limiting sliding groove is arranged on the inner wall of the rotating ring.

[0011] In order to facilitate the disassembly and cleaning of the cleaning cotton block, the utility model is improved in that a T-shaped slot is provided at the top of the rotating block, and a mounting strip adapted to the T-shaped slot is fixed to the bottom end of the cleaning cotton block, and the mounting strip is slidably connected to the T-shaped slot.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a 360-degree panoramic outer wall detection lens with a large field of view, which has the following beneficial effects:

[0014] The 360-degree panoramic outer wall detection lens with a large field of view can quickly clean the dust on the lens surface through a cleaning mechanism. The cleaning column is lowered to a height capable of cleaning the lens through a lifting mechanism. The rotating ring drives the annular gear track, so that the rotating gear drives the rotating block to rotate out of the first rotating groove, so that the cleaning cotton block contacts the lens, and the cleaning column is rotated to complete the cleaning. The normal use of the lens is not affected, and the cleaning of the lens is simple and quick, avoiding the tedious steps of manually cleaning the lens with the help of cleaning tools.

The rotating rack 7 is engaged, and three slots 9 connected to the outer wall of the cleaning column 3 are formed on the first rotating groove 4, and a connecting block 10 is slidably connected to the slot 9, and a rotating ring 11 is fixed on the three connecting blocks 10, and the rotating ring 11 is sleeved on the cleaning column 3. The lifting mechanism includes a fixed rotating ring 12, and the fixed rotating ring 12 is sleeved on the lens barrel 1. The fixed rotating ring 12 is rotatably connected to the outer wall of the lens barrel 1, and a spring 13 is fixed to the bottom end of the fixed rotating ring 12, and an annular fixed block 14 is fixed to the other end of the spring 13, and the annular fixed block 14 is fixed to the inner wall of the cleaning column 3, and the annular fixed block 14 is sleeved on the lens barrel 1.

[0022] When the lens is in use and the lens surface needs to be cleaned, in the initial state, the rotating block 5 is located in the first rotating groove 4, and the cleaning column 3 is above the lens body 2. The cleaning column 3 is manually held and pushed downward, and the spring 13 is stretched, so that the first sliding groove is located below the lens body 2, and then the rotating ring 11 is turned to the rotating ring 11. The rotating ring 11 drives the connecting block 10 and the annular rack to rotate, and the annular rack engages with the rotating rack 7, thereby driving the rotating rack 7 to rotate, and the rotating rack 7 drives the rotating block 5 to rotate, and the rotating block 5 rotates out of the first rotating groove 4. The rotating block 5 and the cleaning cotton block 6 are located directly below the lens body 2, and the cleaning cotton block 6 contacts the lens body 2.

The rotating ring 11 is rotated in the reverse direction to make the rotating block 5 rotate back to the first rotating groove 4, and the spring 13 contracts to drive the cleaning column 3 to recover.

[0023] It is found in actual use that slipping may occur when the rotating ring 11 is rotated. In order to avoid the above problem, in this embodiment, anti-slip grooves are provided on the outer wall of the rotating ring 11.

[0024] It is found in actual use that when the cleaning column 3 is raised or lowered, the rotating block 5 may collide with the lens body 2 or the lens barrel 1 and get stuck. In order to avoid the above problem, in this embodiment, the side of the rotating block 5 close to the central axis of the cleaning column 3 is set to an arc surface with an arc, and the arc of the arc surface on the rotating block 5 is the same as the arc of the inner wall of the cleaning column 3.

[0025] It was found in actual use that the rotating ring 11 was only fixed to the connecting block 10, and would shake and become unstable during rotation.
