Description

Technical Field

[0001] This utility model relates to the field of mechanical suspension technology, and in particular to a mechanical suspension device for an optical position sensor. Background Technology

[0002] Currently, NDI optical position sensors are used to detect optical markers on the body surface. The support devices for NDI optical position sensors are mostly ground-mounted tripods. These devices can fix the optical position sensor in place and allow for a certain range of translation and angle adjustment. If the device is fixed to the ground, the adjustment range of the optical position sensor is limited. If it is not fixed, it needs to be readjusted before each use, making detection very inconvenient.

[0003] The existing utility model patent CN209770541U describes a mechanical suspension device for an optical position sensor. This device includes a first load-bearing beam fixed to the ceiling, a second load-bearing beam intersecting and fixed to the first, an upper column fixed to the second load-bearing beam, and a lower column fixed to the upper end of a lower column via two clamps. The lower column is rotatably connected to one end of a connecting crossbar via a first connecting shaft. The other end of the connecting crossbar is rotatably connected to one end of a connecting bracket via a second connecting shaft. The other end of the connecting bracket is rotatably connected to one end of a fixed bracket via a pin. The other end of the fixed bracket is fixedly connected to a fixing block for fixing the optical position sensor. This mechanical suspension device can fix the optical position sensor and provides adjustment for translation and rotation angles, thereby adjusting the position of the optical position sensor so that the optical marker on the body surface is centered within the sensor's detection range. It is simple and reliable to install and convenient to use.

[0004] However, existing mechanical suspension devices are fixed to the ceiling by the first load-bearing crossbeam. The entire device is heavy and may fall after long-term use. In addition, the fixed position makes it inconvenient to move and has a small applicable area. Furthermore, the adjustment structure with multiple degrees of freedom is complex and the operation is cumbersome. To solve the above problems, a mechanical suspension device with an optical position sensor is proposed. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a mechanical suspension device for an optical position sensor, characterized by comprising a slide rail, a slider, a telescopic frame, an adjusting groove, an adjusting block, a limiting handle, a limiting groove, a locking block, a rotary bearing, a connecting block, a mounting column, a universal ball bearing, and an optical position sensor. The slide rail contains a slider, the telescopic frame is positioned below the slider, the telescopic frame has an adjusting groove, the adjusting groove contains an adjusting block, the adjusting block has a limiting handle, the adjusting block has a locking block, the telescopic frame has a connecting block below it, the connecting block has a mounting column, the mounting column has a universal ball bearing, and the universal ball bearing has an optical position sensor.

[0006] Furthermore, the slide rail is fixed to the ceiling by bolts. The slide rail has a T-shaped cross-section. The upper end of the slider is coupled to the slide rail, and the lower end has several slots. The telescopic frame has several adjustment slots, and the adjustment slots are the same size as the slots of the slider.

[0007] Furthermore, the adjusting block passes through the adjusting groove and the slot of the slider, the limiting handle is located at one end of the adjusting block, the limiting groove is located at the other end of the adjusting block, and the locking block has a protrusion.

[0008] Furthermore, the connecting block is elongated, with one end connected to the telescopic frame via a rotary bearing, and a mounting column at the bottom of the other end. An optical position sensor is mounted on the bottom of the mounting column via a universal ball bearing.

[0009] The beneficial effects of this utility model are:

[0010] This invention utilizes an optical position sensor, allowing it to rotate in multiple directions via a universal ball bearing. When rotation is needed, a connecting block is pushed, causing it to rotate at the bottom of the telescopic frame via a rotary bearing. For vertical adjustment, a locking block is removed from the limiting groove, the limiting handle is grasped, and the adjusting block is removed from the slots of the adjusting groove and the slider. The telescopic frame is then moved up and down to the desired position, aligning the adjusting groove with the different slots of the slider to achieve overall vertical adjustment. For forward and backward adjustment, the telescopic frame is pushed, causing it and the slider to move forward and backward along the slide rail. This invention achieves multi-degree-of-freedom adjustment of the optical position sensor, while maintaining a simple structure and ease of operation. Attached Figure Description
