Description

Technical Field

[0001] This utility model belongs to the field of lens adjustment technology, specifically relating to an optical axis adjustment structure for an optical aiming lens. Background Technology

[0002] For optoelectronic turntables with optical tracking capabilities, a high degree of optical axis consistency is required between the camera's optical axis and the lens's optical axis. The combination of a camera and lens often relies on the threaded couplings provided with the camera and lens themselves for installation and then fixing them to the platform. However, due to the poor machining and installation precision of the lens couplings, it is impossible to guarantee a high degree of optical axis consistency between the assembled camera and lens.

[0003] Currently, most camera and lens optical axis alignment adjustments use one adjustment component for the left and right directions and another for the front and back directions. This results in repeated operation of two adjustment components, making the process cumbersome and inconvenient, and therefore needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide an optical axis adjustment structure for an optical aiming lens to solve the problems existing in the background art.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An optical axis adjustment structure for an optical aiming lens includes a fixed platform and a mounting plate, the mounting plate being used for a camera, and an adjustment mechanism being installed between the fixed platform and the mounting plate.

[0007] The adjustment mechanism includes a limiting frame fixedly connected to the fixed platform, a limiting rod slidably connected to the limiting frame fixedly installed on the mounting plate, a limiting block fixedly installed at the lower end of the mounting plate, an elastic component matching the limiting block installed in the center of the fixed platform, a limiting groove installed at the upper end of the elastic component, and a locking component installed between the mounting plate and the fixed platform.

[0008] The elastic component includes a sliding plate, and the fixed platform has a sliding groove that matches the sliding plate. Several springs are installed between the sliding groove and the sliding plate. A protrusion that abuts against the mounting plate is installed on the upper end of the sliding plate, and the limiting groove is opened on the upper end of the protrusion.

[0009] The limiting block is a hemispherical shape, the limiting groove matches the limiting block, and the depth dimension of the limiting groove is lower than the radius dimension.

[0010] The periphery of each of the aforementioned limiting grooves located inside is adjacent to the six limiting grooves.

[0011] The mounting plate is equipped with an up-and-down adjustment assembly. An adjustment groove is provided inside the mounting plate. An adjustment plate that extends out of the mounting plate is slidably connected inside the adjustment groove. The lens is mounted on the upper end of the adjustment plate. An external threaded cylinder that is threadedly connected to the mounting plate is rotatably mounted on the upper end of the adjustment plate.

[0012] The locking assembly includes a threaded post that is threadedly connected to the adjusting plate, a limit post installed at the lower end of the threaded post, and a fixing groove that matches the limit groove on the fixing platform.

[0013] The number of limiting frames is six, with two limiting frames on each of the left and right sides of the fixed platform, and one limiting frame on each of the front and rear sides of the fixed platform.

[0014] This invention uses a locking assembly to connect and unlock, allowing the mounting plate to be freely adjusted in the horizontal direction when the locking is released. At the same time, the adjacent limiting grooves and elastic components generate resistance during adjustment, ensuring that the adjustment passes through the limiting grooves one by one, avoiding over-adjustment. Furthermore, multiple directions of adjustment (left, right, forward, and backward) can be achieved through a single locking assembly, making operation convenient and quick.

Detailed Implementation

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1: As Figure 1-6 As shown, the optical axis adjustment structure of an optical aiming lens of this utility model includes a fixed platform 1 and a mounting plate 11. The mounting plate 11 is used for a camera 12, and an adjustment mechanism is installed between the fixed platform 1 and the mounting plate 11.

[0026] The adjustment mechanism includes a limiting frame 13 fixedly connected to the fixed platform 1, a limiting rod 14 slidably connected to the limiting frame 13 fixedly installed on the mounting plate 11, a limiting block 15 fixedly installed at the lower end of the mounting plate 11, an elastic component matching the limiting block 15 installed in the center of the fixed platform 1, a limiting groove 16 installed at the upper end of the elastic component, and a locking component installed between the mounting plate 11 and the fixed platform 1.

[0027] When the locking assembly is connected, the mounting plate 11 is fixedly installed on the fixed platform 1 and cannot be moved. When adjustment is needed, the locking assembly is disconnected, and the mounting plate 11 can move freely left, right, forward, and backward. During the adjustment and movement, the limiting block 15 will move, and the limiting block 15 will press the elastic component during the movement. The elastic component will drive the limiting groove 16 to move downward and disengage from the limiting block 15, so that the mounting plate 11 can move freely horizontally. After the movement is completed, the elastic component will move upward due to its rebound force, so that the limiting groove 16 will be inserted into the limiting block 15. Finally, the locking assembly can be connected.

[0028] The locking assembly can be a threaded rod connection structure using conventional techniques in the art, so that the threaded rod is threadedly connected to the mounting plate 11 and the fixed platform 1, thereby achieving the function of connecting the mounting plate 11 and the fixed platform 1 through the threaded connection of the threaded rod.

[0029] The limiting block 15 is a hemispherical shape, and the limiting groove 16 matches the limiting block 15, with the depth dimension of the limiting groove 16 being lower than its radius dimension.

[0030] The elastic component includes a sliding plate 20. The fixed platform 1 has a sliding groove 21 that matches the sliding plate 20. Several springs 22 are installed between the sliding groove 21 and the sliding plate 20. A protruding plate 23 that abuts against the mounting plate 11 is installed on the upper end of the sliding plate 20. A limiting groove 16 is opened on the upper end of the protruding plate 23.

[0031] The limiting groove 16 is a combination of a spherical bottom and a conical top, which allows the hemispherical limiting block 15 to move through the inclined conical surface when sliding, thereby pushing the convex plate 23 to move downward against the rebound force of the spring 22. In this way, it can slide out from any angle of the limiting groove 16 into another adjacent limiting groove 16, thus allowing it to move freely in the horizontal direction.

[0032] This invention uses a locking assembly to connect and unlock, allowing the mounting plate to be freely adjusted in the horizontal direction when the locking is released. At the same time, the adjacent limiting grooves and elastic components generate resistance during adjustment, ensuring that the adjustment passes through the limiting grooves one by one, avoiding over-adjustment. Furthermore, multiple directions of adjustment (left, right, forward, and backward) can be achieved through a single locking assembly, making operation convenient and quick.

[0033] Example 2: Based on Example 1, a further improvement is made, wherein the periphery of the several limiting grooves 16 located inside is adjacent to the six limiting grooves 16.

[0034] The limiting groove 16 in the center spreads evenly to the periphery, so that there are six identical limiting grooves 16 on the periphery of all the limiting grooves 16 except the outermost ones. This makes the upper edge of the limiting groove 16 an inclined hexagon, which facilitates the sliding movement of the limiting block 15 to the inclined side, and thus facilitates adjustment.

[0035] The mounting plate 11 houses a height adjustment assembly. An adjustment groove 24 is formed within the mounting plate 11, and an adjustment plate 25 extends out of the mounting plate 11 and is slidably connected within the adjustment groove 24. The lens 12 is mounted on the upper end of the adjustment plate 25. An external threaded cylinder 26, threadedly connected to the mounting plate 11, is rotatably mounted on the upper end of the adjustment plate 25. When height adjustment is required, rotating the external threaded cylinder 26 moves the adjustment plate 25 up and down. Because the adjustment plate 25 can only slide up and down within the adjustment groove 24, the external threaded cylinder 26, threadedly connected to the adjustment plate 25, can move the adjustment plate 25 up and down during rotation, thus adjusting the height of the lens 12.

[0036] The locking assembly includes a threaded post 27 threadedly connected to the adjusting plate 25. A limit post 28 is installed at the lower end of the threaded post 27. The fixed platform 1 is equipped with a fixed groove 29 that matches the limit groove 16. The threaded connection between the threaded post 27 and the adjusting plate 25 fixes the relationship between the adjusting plate 25 and the mounting plate 11. The limit post 28 is inserted into the fixed groove 29 to fix the horizontal position of the mounting plate 11. The adjusting plate 25 is fixed in the longitudinal direction by the external threaded cylinder 26 in the up-down adjustment assembly. Since the adjusting plate 25 cannot slide left, right, forward, or backward, the limit post 28 can be stably inserted into the fixed groove 29. When the mounting plate 11 needs to be adjusted horizontally, the threaded post 27 is rotated to move it upward, causing the limit post 28 to disengage from the fixed groove 29. The height of the fixed groove 29 is greater than the height of the adjusting groove 24.

[0037] There are six limiting frames 13 in total. There are two limiting frames 13 on each of the left and right sides of the fixed platform 1, and one limiting frame 13 on each of the front and rear sides of the fixed platform 1. The length of the limiting rod 14 is greater than the stroke of the limiting groove 16, so that the limiting rod 14 will not detach from the limiting frame 13 during the horizontal sliding process inside the limiting frame 13.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
