Description

Fixed knot constructs and radiotherapy fixing device Technical Field The utility model relates to the technical field of radiotherapy apparatuses, in particular to a fixing structure and a radiotherapy fixing device. Background When a patient is subjected to radiotherapy, the patient is usually laid on a specific base, and then the therapeutic position of the patient is fixed on the base by using a positioning membrane, and the therapeutic position of the patient is subjected to image scanning and then is treated. However, due to the differences of the body type and the treatment position of the patient, the fixed position of the diaphragm is usually required to be adjusted on the base, and the diaphragm is usually required to be repeatedly clamped when the position of the diaphragm is adjusted, so that the diaphragm is easily damaged. The prior art separates diaphragm fixed knot constructs with base fixed knot constructs, and the buckle formula fixed knot that diaphragm fixed knot constructs often adopts constructs, and it is most convenient that it is buckle structure operation that belongs to cut straightly wherein, when the treatment chest belly disease, breathes and leads to chest belly to rise and fall, and chest belly to rise and fall and produce very big tension to the diaphragm, and the buckle is collapsed easily to influence fixed stability and the effect of treatment. Disclosure of utility model The utility model aims to overcome the defect that a diaphragm is easy to separate from a fixing structure in the treatment process in the prior art, and provides the fixing structure and the radiotherapy fixing device, wherein the diaphragm is not easy to separate from the fixing structure in the treatment process. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a fixed knot constructs, including fixing base and knob, the fixing base is equipped with first mount table and is used for placing the second mount table of installation thing, first mount table is higher than the second mount table, the knob rotates to be established on the first mount table, the knob with be equipped with the location structure that is used for fixed the installation thing between the second mount table. According to the fixing structure, when the installation object is fixed, the fixing structure is integrally fixed on the base through the fixing base, the knob is initially integrally positioned on the first installation table, the installation object is placed on the second installation table, then the knob is rotated to the position above the installation object, the knob and the second installation table clamp and fix the installation object, and meanwhile the positioning structure fixes the installation object. The rotary knob is rotated to fix the installation object, so that the installation object is prevented from moving up and down when the chest and abdomen are fluctuated, the installation object is not easy to separate from the fixing structure in the treatment process, and the rotary knob is rotated to release the fixing of the installation object, so that the operation is convenient. Further, the positioning structure comprises a first positioning piece and a second positioning piece matched with the first positioning piece, the first positioning piece is arranged on the knob, and the second positioning piece is arranged on the second mounting table. After the installation object is placed on the second installation table, the knob is rotated to enable the first locating piece to be matched with the second locating piece, and the installation object is fixed. Further, the first positioning piece comprises a positioning block, the positioning block is arranged on the knob, the second positioning piece comprises a positioning groove matched with the positioning block, and the positioning groove is arranged on the second mounting table. Placing the installation object on the second installation table, aligning the holes on the installation object with the positioning grooves, rotating the knob to enable the positioning block to be inserted into the positioning grooves, enabling the positioning block to penetrate through the holes on the installation object at the same time, and facilitating positioning of the installation object while fixing the installation object. Further, the first positioning piece further comprises an elastic piece, a sliding groove is formed in the knob, the positioning piece is in sliding connection with the sliding groove, and two ends of the elastic piece are respectively connected with the knob and the positioning piece. When the installation object is taken out, the knob is rotated, the elastic piece is compressed to drive the positioning block to slide into the sliding groove, so that the positioning block is conveniently separated from the positioning groove, and the installation object is prevented from being
