Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

With reference to fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5, the present embodiment discloses a safe extendable cover plate mechanism for a rotating frame for proton therapy, which includes a therapy head 6, a rotating frame 7, and an extendable cover plate mechanism 8; a treatment head 6 is arranged on the rotating frame 7; the treatment head 6 rotates along the rotating frame 7; an extensible cover plate mechanism 8 is arranged at the lower part of the rotating frame 7; in this embodiment, in proton treatment, the in-process of 7 work of rotating frame, when treatment head 6 is in the below ground, stretch out protractile apron mechanism 8, the utility model discloses according to treatment head 6 position, the control corresponds the mechanism and stretches out, guarantees that ground is flat, does not have big step. The step filling process is flexible, and the step range can be reduced as much as possible according to the position of the treatment head 6.

With reference to fig. 6, 7, 8, and 9, in order to implement the structure of the extendable cover plate mechanism, the extendable cover plate mechanism 7 further includes a base 1, a motor 2, a chain 3, a guide rail 4, and a sliding plate 5; the base 1 is fixed on the ground 9, a bottom plate 10 is fixed above the base 1, and two parallel guide rails 4 are fixed on two sides of the bottom plate 10; a motor 2 is fixedly connected to a bottom plate 10 between the two guide rails 4, a driving chain wheel 11 is arranged on the motor 2, and the driving chain wheel 11 is connected with a driven chain wheel 12 through a chain 3 to form chain transmission; a slide block 13 is arranged on the guide rail 4; fixed sliding plates 5 are arranged on two sides of the guide rail 4; a chain joint 14 is arranged on the chain 3, the chain joint 14 is connected with the sliding plate 5 through a pin shaft 15, and the sliding plate 5 is driven by the chain 3; in the above structure, the treatment head 6 rotates in the rotating frame 7 for 360 degrees around the rotating center, and a part of the inner ring of the rotating frame 7 is located under the ground, so that a step is formed.
