Description

Technical Field

[0001] The utility model relates to the technical field of X-ray emission, in particular to an out-beam port position adjustment device. Background Art

[0002] X-rays are harmful. When producing an X-ray device, a device for restricting the irradiation range of the rays must be installed. This device can limit the irradiation range of X-rays. However, when installed, its position must be exactly coincident with the out-beam axis of the X-ray generator and the three axes of the external aluminum alloy housing to output the part with the strongest ray energy; at the same time, useless ray irradiation in other parts should be reduced as much as possible. Therefore, the installation of the ray out-beam limiting device is particularly important; usually, the empirical method is adopted for installation, that is, after installation, by taking one X-ray picture after another, observing whether the position of the out-beam port is appropriate, then readjusting the position of the out-beam port, taking another picture and checking whether the position is appropriate, and repeating this step until the appropriate position is adjusted. After adjusting the horizontal direction, this step needs to be repeated to adjust the vertical direction. This process is time-consuming and laborious, and at the same time, the equipment needs to be disassembled and assembled every time an adjustment is made, which is extremely likely to cause unnecessary production losses.

[0003] For example, the patent with the publication number CN208317087U discloses an X-ray emission cavity and an emission source machine, including an X-ray emission tube, a shielding cylinder, an anode end plug, a cathode end plug and an out-beam port. The anode end plug and the cathode end plug are respectively arranged at both ends of the shielding cylinder to form a closed cavity; the X-ray emission tube is located inside the shielding cylinder, and both ends of the X-ray emission tube are respectively arranged on the anode end plug and the cathode end plug; the out-beam port is arranged on the shielding cylinder, and the out-beam port corresponds to the focus of the X-ray emission tube. The X-rays emitted by the X-ray emission tube are emitted from the out-beam port for work. The X-ray emission cavity of the utility model effectively prevents X-Ray leakage during the operation of the emission source, ensures the safety of operators, and conducts close-range protection on the X-Ray source, with remarkable protection effect. Moreover, due to the small protection space, accidental reflection of X-Ray can be avoided, greatly reducing the number of leakage potential points, greatly reducing the volume and weight of the protection structure, and facilitating operation.

[0004] However, the X-ray emission source machine in the above technology still has the following problems:

[0005] During use, the position irradiated by the X-rays emitted from the out-beam port will have a certain deviation. This requires, after frequent irradiation, according to the deviation degree of the taken photos, constantly adjusting the position of the out-beam port through experience, and the operation is cumbersome.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figure 1 - Figure 5 , a beam outlet position adjustment device, including a beam outlet port 2 provided on the transmitter 1. The inner wall of the beam outlet port 2 is connected with a cross-shaped measuring scale 3. The cross-shaped measuring scale 3 includes a positioning measuring scale 4 and an adjustable measuring scale 5. The positioning measuring scale 4 abuts against the side of the beam outlet port 2 away from the transmitter 1, the adjustable measuring scale 5 is connected with the inner wall of the beam outlet port 2, and a rotating assembly is connected between the positioning measuring scale 4 and the adjustable measuring scale 5. A plurality of equally spaced scale lines 6 are provided on one side of the positioning measuring scale 4 and the adjustable measuring scale 5.

[0023] As Figure 1 - Figure 5 shown, a beam outlet position adjustment device in the present utility model is similar in structure to the existing beam outlet position adjustment device. For example, an X-ray emission cavity and a transmitter disclosed in a patent with the publication number CN208317087U. The main improvement point of the present utility model is that the position of the beam outlet port 2 of the transmitter 1 can be adjusted more quickly. As Figures 1 to 5As shown in the figure, when the beam output port position adjusting device in the present utility model is in use, the positioning scale 4 and the adjusting scale 5 are respectively aligned with the length and width of the beam output port 2 through the rotating assembly. Subsequently, the adjusting scale 5 is abutted against the inner wall of the beam output port 2 of the radiation source machine 1, and the positioning scale 4 is abutted against the outer wall of the beam output port 2. When the radiation source machine 1 emits X-rays, the X-rays emitted through the beam output port 2 will pass through the cross scale 3 installed in the middle of the beam output port 2, and the shape of the cross scale 3 will be irradiated on the photo. Subsequently, according to the scale lines 6, the offset distance between the positioning scale 4 and the adjusting scale 5 on the photo is calculated, and the position of the beam output port 2 is adjusted, so as to quickly and accurately complete the position adjustment of the beam output port 2 of the radiation source machine 1, without the need for the empirical method, reducing the cumbersome operation of repeatedly taking photos for adjustment and improving the adjustment efficiency of the beam output port 2.

[0024] As Figure 1 - Figure 5 shown in the figure, the scale lines 6 are made of lead. Making the scale lines 6 of lead, the blocking effect of lead on the rays enables the scale lines 6 to appear on the X-ray photo, so as to smoothly obtain the offset distance of the beam output port 2.

[0025] As Figure 1 - Figure 5 shown in the figure, the adjusting scale 5 includes a fixed scale sleeve 7 and two telescopic scale rods 8. Both ends of the fixed scale sleeve 7 are provided with telescopic slots 701, and the two telescopic scale rods 8 are respectively slidably connected with the two telescopic slots 701. Both ends of the fixed scale sleeve 7 close to the positioning scale 4 are provided with two positioning sliding slots 702, and the two positioning sliding slots 702 are respectively communicated with the two telescopic slots 701. Positioning components are connected in the two positioning sliding slots 702, and the two positioning components are respectively connected with the two telescopic scale rods 8. The mutually remote ends of the two telescopic scale rods 8 are respectively abutted against the inner walls on both sides of the beam output port 2. When installing the adjusting scale 5, the two telescopic scale rods 8 are respectively slid into the telescopic slots 701 at both ends of the fixed scale sleeve 7, and the fixed scale sleeve 7 is inserted into the beam output port 2. Subsequently, the two telescopic scale rods 8 are drawn outwards from the telescopic slots 701 and abutted against the inner wall of the beam output port 2. After adjustment, the positioning components are used to fix the telescopic scale rods 8 and the fixed scale sleeve 7, so as to fixedly install the cross scale 3 on the beam output port 2 by the mutual cooperation of the two telescopic scale rods 8.

[0026] As Figure 1 - Figure 5As shown in the figure, the positioning assembly includes an internally threaded tube 9 and a hand-tightening bolt 10. The internally threaded tube 9 is fixedly connected to one end of the telescopic ruler rod 8 close to the telescopic groove 701 and on the side close to the positioning chute 702. The outer wall of the internally threaded tube 9 is slidably connected to the inner wall of the positioning chute 702. The threaded rod of the hand-tightening bolt 10 is threadedly connected to the internally threaded tube 9, and the nut of the hand-tightening bolt 10 abuts against the fixed ruler sleeve 7. By screwing the hand-tightening bolt 10 into the internally threaded tube 9, the nut of the hand-tightening bolt 10 is abutted against the outer wall of the fixed ruler sleeve 7, and the inner telescopic ruler rod 8 is abutted against the inner side of the telescopic groove 701, thereby completing the connection and fixation of the telescopic ruler rod 8 in the telescopic groove 701. At the same time, when the telescopic ruler rod 8 slides in the telescopic groove 701, the sliding between the internally threaded tube 9 and the positioning chute 702 can prevent the telescopic ruler rod 8 from being pulled out of the telescopic groove 701, improving the connection stability between the telescopic ruler rod 8 and the fixed ruler sleeve 7.

[0027] As Figure 1 - Figure 5 As shown in the figure, the rotating assembly includes a T-shaped rotating rod 11 and a fastening bolt 12. The thinner end of the T-shaped rotating rod 11 passes through the middle position of the fixed ruler sleeve 7 and the positioning ruler 4 and is threadedly connected to the fastening bolt 12. Both the fixed ruler sleeve 7 and the positioning ruler 4 are rotatably connected to the thinner end of the T-shaped rotating rod 11. When installing and adjusting the ruler 5 and the positioning ruler 4, the thinner end of the T-shaped rotating rod 11 is passed through the installation hole opened in the middle of the adjusting ruler 5 and the positioning ruler 4, and then the fastening bolt 12 is tightened with the thin rod of the T-shaped rotating rod 11 by threading, so that the adjusting ruler 5 and the positioning ruler 4 can be fixed. When it is necessary to adjust the angle between the adjusting ruler 5 and the positioning ruler 4, the fastening bolt 12 is loosened.

[0028] As Figure 1 - Figure 5 As shown in the figure, a number of scale lines 6 are respectively located on the side of the positioning ruler 4 away from the fixed ruler sleeve 7 and on the sides of the two telescopic ruler rods 8 close to the positioning ruler 4. The scale lines 6 are arranged on the same side of the positioning ruler 4 and the telescopic ruler rods 8, which is convenient for observation during installation and convenient for installing the cross ruler 3 at the middle position of the beam output port 2.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
