The invention discloses a positioning anti-deviation base for vehicle-mounted CT, and relates to the technical field of vehicle-mounted CT. The positioning anti-deviation base for CT comprises a CT bed, a CT machine and a base, the CT bed is located on one side of the CT machine, the CT bed comprises a bed body and the base, the bed body is arranged on the outer surface of the upper end of the base, and the outer surface of the lower end of the base is connected with the base through a connecting piece; the anti-deviation mechanism is arranged, a bolt penetrates through a first threaded hole and a second threaded hole, so that the base is in threaded connection with a preset part arranged at the bottom of the vehicle, the base is fixed, the CT bed is prevented from moving in the direction perpendicular to the bolt, and on the basis, rotation of a first gear is hindered through elastic force of a torsion spring; meanwhile, the restoring capacity of the torsion spring can drive the second gear to drive the first gear to rotate in the original state restoring direction, and therefore the CT bed can be corrected in time when the CT bed deviates by a small angle.
本发明公开了一种车载CT用定位防偏移基座,涉及车载CT技术领域。CT用定位防偏移基座包括CT床、CT机以及底座,CT床位于CT机的一侧,且CT床包括床体与底座,且床体设置于底座的上端外表面,底座的下端外表面通过连接件连接有基座;本发明通过设置防偏移机构,利用螺栓贯穿螺纹孔一以及螺纹孔二,使基座与车底部设置的预设件螺纹连接,从而对基座进行固定,并防止CT床沿垂直与螺栓方向移动,在此基础上,利用扭转弹簧的弹力对齿轮一的转动造成阻碍,增加CT床转动的阻力,同时扭转弹簧的恢复能力能够驱使齿轮二带动齿轮一向恢复原状的方向转动,从而能够在CT床发生较小角度偏移时对其进行及时地纠正。
