Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a hair photography stand for diagnosing and treating patients with hair loss. Background Technology

[0002] Hair photography frames are medical devices used in hospitals to diagnose and treat patients with hair loss, helping doctors to gain a comprehensive understanding of the hair condition in the affected area.

[0003] In the prior art, such as Chinese Publication No. CN216852104U, this utility model belongs to the field of photographic frame technology and discloses a hair photographic frame for the diagnosis and treatment of hair loss patients. It includes a base plate, an adjustment plate, a rotating column, a rotating rod, and a camera. A fixing block and a placement plate are fixedly installed on the top of the base plate. A moving mechanism is movably connected inside the fixing block. A support plate is fixedly installed on the top of the back of the fixing block. A forehead clip is fixedly installed on the top of the support plate. Hinge blocks are fixedly installed on the back of the support plate and the top of the moving mechanism. This utility model drives the hinge blocks and the adjustment rod to gradually rotate under the drive of the two hinge blocks. During the rotation, the adjustment rod pushes upward against the support plate until the patient finds a suitable support position. This makes the slider, the adjustment rod, and the hinge blocks form a stable support mechanism, avoiding excessive deformation of the support plate under force, making the support of the forehead clip more stable and the patient more comfortable to use.

[0004] While the above solutions have the advantages mentioned above, their disadvantages are as follows: They lack a structure that allows the motor output to drive the gears, which in turn rotates the gear plate inside the moving frame. This prevents the device from adjusting the lateral angle at which the imaging mechanism can capture images of the patient's affected area. They also lack a structure that allows the motor output shaft to rotate, which in turn moves the sliding plate and imaging mechanism along the limiting groove. This prevents the device from adjusting the longitudinal angle at which the imaging mechanism can capture images of the patient's affected area. Furthermore, the device cannot capture images of the patient's affected area from multiple angles. Finally, it lacks a structure that allows adjustment of the imaging height based on the patient's height, and it lacks a structure that uses shock-absorbing damping and a buffer spring to protect the imaging mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a hair photography stand for the diagnosis and treatment of hair loss patients. This invention features a structure where a motor output drives a gear to rotate, which in turn drives a gear plate to rotate inside the moving frame. This allows the device to adjust the lateral angle at which the imaging mechanism photographs the patient's affected area. It also features a structure where the motor output shaft rotates, driving a rotating shaft to rotate, which in turn moves a sliding plate and the imaging mechanism along a limiting groove. This allows the device to adjust the longitudinal angle at which the imaging mechanism photographs the patient's affected area. The device can photograph the patient's affected area from multiple angles. Furthermore, it includes a structure that adjusts the imaging height of the imaging mechanism according to the patient's height, and a structure that uses shock-absorbing damping contraction combined with a buffer spring to protect the imaging mechanism.

The rotation of the rotating shaft 21 drives the second gear 20 to move around the toothed rail 17, thereby driving the two sliding plates 18 and the shooting mechanism 22 to move along the limiting slide groove 16.

[0028] Furthermore, such as Figures 1 to 4 As shown, a third motor 19 is fixedly installed on the outer surface of the sliding plate 18.

[0029] Furthermore, such as Figures 1 to 4 As shown, a lead screw 6 is threadedly connected to the inner surface of the movable frame 1, and two guide slide rods 8 are slidably connected to the inner surface of the movable frame 1. When the lead screw 6 rotates, with the cooperation of the guide slide rods 8 on both sides, the lead screw 6 drives the movable frame 1 to slide in the vertical direction.

The adjusting frame 7 is fixedly connected to the two end faces of the two guide slide rods 8. The inner surface of the adjusting frame 7 is slidably connected to the outer surface of the movable frame 1. The movable frame 1 is used to install the lead screw 6 and the two guide slide rods 8.

This allows the device to adjust the shooting height of the imaging mechanism 22 according to the patient's height. When the moving frame 1 contacts the protective plate 11, the shock-absorbing damper 9 contracts in conjunction with the buffer spring 10 to dampen and buffer the vibrations of the moving frame 1, thus protecting the imaging mechanism 22.
