Description

Technical Field

[0001] The utility model belongs to the technical field of calcaneus adjustment devices, and relates to an angle adjustment device for a calcaneus acquisition component. Background Technique

[0002] The calcaneus is the largest tarsal bone in the foot, an irregular rectangular structure composed of a thin layer of cortical bone surrounding rich cancellous bone; the calcaneus plays an important role in the study of foot biomechanics and orthopedic medicine in the human body; however, in life, calcaneal deformities can be caused by genetic factors, overuse, unsuitable shoes, abnormal foot structure, as well as trauma or injury. Once the calcaneal deformity is relatively severe, obvious phenomena such as flat foot arch or unequal leg length will occur, and pain will also occur in the heel area. Therefore, it is necessary to evaluate the calcaneus to timely understand the growth of the calcaneus.

[0003] The existing method for measuring the calcaneus is that the measurer stands on a measurement platform, collects a picture of the calcaneus through a calcaneus acquisition device, processes the picture, and then obtains the calcaneus data to achieve the evaluation of the calcaneus. However, in actual measurement, in order to ensure that the calcaneus falls within the acquisition range of the acquisition device, before acquisition, it is necessary to adjust the acquisition angle of the calcaneus acquisition device according to the standing position of the measurer and the size of the foot.

[0004] Referring to the Chinese patent document with the reference application number CN202410113619.7, it discloses a child behavior data acquisition device including a main body including a base and a calcaneus acquisition component arranged on the top of the base; a hidden mechanism arranged on the top of the base; an adjustment mechanism arranged between the base and the calcaneus acquisition component; and a control mechanism arranged on the adjustment mechanism.

By starting the motor, the electromagnetic rotors to which the first screw rod and the second screw rod belong are driven to move in opposite directions synchronously to adjust the air gap size between them and the copper rotor, so as to adjust their transmission torque, thereby quickly adjusting the rotation speeds of the first screw rod and the second screw rod, driving the calcaneus acquisition component to swing its head up and down, so as to finely adjust the main imaging angle of the calcaneus acquisition component, which is convenient for personnel to use.

[0005] Although the existing angle adjustment mechanism can realize the angle adjustment of the calcaneus acquisition component, when the existing adjustment mechanism is adjusting, it drives the calcaneus acquisition component to swing its head up and down, and cannot realize the adjustment of the rotation angle, making it difficult to ensure the consistency between the imaging picture collected by the calcaneus acquisition component and the design, resulting in poor accuracy of the subsequent calcaneus data.
