[0002] Optical lenses are lenses made of optical glass. The definition of optical glass is glass with specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance and light absorption, and with uniform optical properties.

[0003] When measuring an optical lens, it is necessary to measure multiple data such as its diameter tolerance, center thickness tolerance, and curvature radius. Therefore, when measuring the lens, it is necessary to use a measuring head with different parameters to measure the multi-source data of the optical lens. The measuring head fixing method in the prior art usually adopts a fixed thread method for fixing. This method is troublesome to disassemble and assemble, and is time-consuming and labor-intensive. In addition, the measuring head may become loose during working, causing the position of the measuring head to change, thereby affecting the accuracy of the measurement data.

[0004] Therefore, a new solution is needed to solve this problem Utility Model Content

[0005] In view of the above background technology, the existing technology has the problem that the measuring head is inconvenient to be disassembled and assembled and is prone to loosening.

[0012] Furthermore, an adjusting rod is threadedly connected inside each of the fixed clamping blocks, and an outer surface of each of the adjusting rods is rotatably connected to the rotating seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is provided with components such as a fixed sleeve, a slot, a lower fixed ring and a spring. When using the device, the two connecting posts of the measuring head are aligned with the corresponding inclined slots, and then the measuring head is rotated to move toward the inside of the fixed sleeve. The upper end of the measuring head will lift the lower fixed ring. When the connecting post moves to the slot position, the spring pushes the lower fixed ring and the measuring head to move downward, so that the connecting post enters the slot. When the measuring head needs to be removed, the measuring head is pushed upward again to disengage the connecting post from the slot and the measuring head can be removed, so that the device can facilitate the disassembly and replacement of the measuring head according to needs.

Through the connection between the spring 5 and the lower fixing ring 6, the lower fixing ring 6 can be conveniently reset under the influence of the elastic force of the spring 5 after rising.

[0024] In a preferred embodiment, the outer surface of the lower fixing ring 6 is slidably connected to the fixed sleeve 1, and the sliding connection between the lower fixing ring 6 and the fixed sleeve 1 can limit the moving direction of the lower fixing ring 6 to avoid tilting during up and down movement. A measuring head 7 is inserted into the inner wall of the fixed sleeve 1. The measuring head 7 can be conveniently installed with different types of detection lenses 9, and the detection lenses 9 can be conveniently connected and matched with the measuring device body 20 for detection. The outer surface of the measuring head 7 is fixedly connected to two connecting columns 8, and the connecting columns 8 can be conveniently connected to the fixed sleeve 1. The outer surface of each connecting column 8 is in contact with the corresponding card slot 3.

The fixing seat 15 can facilitate the installation of the bracket 14 and the installation of the components for fixing the optical lens. The fixing seat 15 is internally rotatably connected to a rotating seat 16. The rotating seat 16 can conveniently drive the optical lens to rotate horizontally, which is convenient for multi-angle measurement.

[0026] See also Figure 1 and Figure 2 The interior of the rotating seat 16 is provided with sliding grooves 17 arranged at equal distances.
