Problems solved by technology

The current guiding method is linear guide rail or slider. Linear guide rail is a commonly used guiding mechanism in the industrial field, but it is more expensive and requires high installation accuracy; the cost of slider is lower, but the assembly needs to be adjusted, and the sliding friction Larger, the slider will wear out after long-term use, and the service life is shorter

Abstract

The invention discloses an oral cavity CBCT device and a guide structure for the same. The guide structure comprises a guide seat and at least one rolling component and is characterized in that the guide seat is provided with a mounting part and a guide part which are connected; each rolling component is mounted on the guide part and provided with a rolling face, the rolling face is provided witha rolling body, and the rolling body component is in rolling connection with the height adjusting column of the oral cavity CBCT device through the rolling body to guide the height adjusting column tomove vertically. The guide structure has a guide function and is low in assembling precision requirements, large in error tolerance, small in rolling resistance, low in cost and long in service life.

Description

technical field [0001] The present invention relates to the technical field of oral CBCT devices, in particular to a guide structure for oral CBCT devices and an oral CBCT device having the guide structure for oral CBCT devices. Background technique [0002] Three-in-one (i.e., CT (Computed Tomography, computer tomography), panoramic and lateral) oral CBCT (Cone beam Computer Tomography, cone beam projection computerized tomography) device in the related art, height adjustment column belt The main swivel arm and lateral arm slide up and down to adjust the height to accommodate different patient heights. [0003] Due to the long and heavy cantilevers of the main rotating arm and the side arm, the height adjustment column is subject to forward and roll moments in the corresponding directions, which in turn affects the stability of the height adjustment column when it moves up and down. The current guiding method is linear guide rail or slider. Linear guide rail is a commonly ...
