[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] Reference Figure 1 As shown, an X-ray tube assembly 1000 provided in an embodiment of the present invention includes a mounting plate 100, an X-ray tube 200, a cathode mounting bracket 300, and an anode mounting bracket 400.

[0033] Mounting plate 100 can be configured as a PCB, and X-ray tube 200 can be configured as a fixed anode type X-ray tube. (See reference...) Figure 1 As shown, the outer peripheral wall of the X-ray tube 200 is provided with a first light exit port 210, which is used to emit X-rays and can also be understood as the focal point of the X-ray tube 200. (Refer to...) Figure 2 As shown, the cathode mounting bracket 300 has a ring-shaped structure and is sleeved on the outer periphery of the X-ray tube 200. The cathode mounting bracket 300 is fixedly connected to the mounting plate 100 by the first fastener 310.

[0034] Reference Figure 2 , Figure 3 and Figure 4 As shown, the anode mounting bracket 400 includes an integrally connected cylindrical part 410 and a connecting seat 430. The cylindrical part 410 is fitted around the outer periphery of the X-ray tube 200. The outer periphery wall of the cylindrical part 410 is provided with a first clearance opening 411 for avoiding the first light outlet 210. The connecting seat 430 is fixedly connected to the mounting plate 100 by a second fastener 450 and fixedly connected to the X-ray tube 200 by a third fastener 460.

[0035] Reference Figure 2 and Figure 4As shown, in some embodiments, the third fastener 460 is configured as a screw. The end of the X-ray tube 200 is provided with a column portion 220, which is provided with a first threaded hole 221. The connecting seat 430 is provided with a first through hole 4321. The third fastener 460 passes through the first through hole 4321 and is threadedly engaged with the first threaded hole 221. The connecting seat 430 is provided with an opening 440, which is used to expose the column portion 220. During the assembly of the X-ray tube 200 and the anode mounting bracket 400, it is convenient to observe whether the column portion 220 and the first through hole 4321 are aligned through the opening 440, and it is convenient to screw the third fastener 460 into the first threaded hole 221.

[0036] When assembling the X-ray tube assembly 1000 of this embodiment, firstly, the X-ray tube 200 is inserted into the cylindrical portion 410 of the anode mounting bracket 400, and the X-ray tube 200 is rotated so that the first light outlet 210 of the X-ray tube 200 is aligned with the first clearance opening 411, ensuring that the X-ray focal point of the X-ray tube 200 is not blocked and remains in the same position. Then, the third fastener 460 is tightened to fix the X-ray tube 200 and the anode mounting bracket 400. During this process, it can be observed through the opening 440 whether the cylindrical portion 220 of the X-ray tube 200 is aligned with the first through hole 4321 of the connecting seat 430, ensuring... Ensure the third fastener 460 is accurately screwed into the first threaded hole 221, then place the cathode mounting bracket 300 around the X-ray tube 200, and then tighten the first fastener 310 and the second fastener 450, thereby fixing the cathode mounting bracket 300 and the anode mounting bracket 400 onto the mounting plate 100, thus completing the installation. The assembly is relatively convenient. The cathode mounting bracket 300 and the anode mounting bracket 400 provide support for the X-ray tube 200. The X-ray tube assembly 1000 is easy to assemble, can achieve modular production, improve production efficiency, reduce manpower and material resources, and promote low-carbon emission reduction.

[0037] Reference Figure 2 and Figure 4 As shown, in some embodiments, the connecting seat 430 includes a connecting portion 431 and a thickened portion 432. The connecting portion 431 mainly serves a connecting function, connecting the thickened portion 432 and the cylindrical portion 410. The second fastener 450 is set as a screw. The connecting portion 431 is provided with a second threaded hole 4311. The mounting plate 100 is provided with a second through hole 110. The second fastener 450 passes through the second through hole 110 and is threadedly engaged with the second threaded hole 4311. The maximum wall thickness of the thickened portion 432 is greater than the maximum wall thickness of the connecting portion 431. The first through hole 4321 is provided in the thickened portion 432. Since the thickened portion 432 supports the cylindrical portion 220 of the X-ray tube 200, the thickness of the thickened portion 432 is relatively large, which can strengthen the structural strength, thereby improving the support effect and making the connecting seat 430 less prone to breakage.

[0038] like Figure 6 As shown, the maximum wall thickness of the connecting part 431 is T1, and the maximum wall thickness of the thickened part 432 is T2. T2 is greater than T1, so that the wall thickness of the thickened part 432 is relatively larger than that of the connecting part 431, which can enhance the structural strength of the thickened part 432.

[0039] Reference Figure 2 and Figure 4 As shown, in some embodiments, the first fastener 310 is configured as a screw, the mounting plate 100 is provided with a third through hole 120, the cathode mounting bracket 300 is provided with a third threaded hole 320, and the first fastener 310 passes through the third through hole 120 and is threadedly connected to the third threaded hole 320.

[0040] Reference Figure 2 and Figure 3 As shown, in some embodiments, the second through hole 110 extends along the axial direction of the X-ray tube 200. It can also be understood that the second through hole 110 is set as an oblong hole. When the second fastener 450 is loosened, the second fastener 450 can move along the axial direction of the X-ray tube 200 within the second through hole 110 to adjust its position and facilitate assembly.

[0041] Reference Figure 2 and Figure 4 As shown, in some embodiments, the end face of the thickened portion 432 is provided with a groove 4322, and the bolt head of the third fastener 460 abuts against the bottom wall of the groove 4322, so that the third fastener 460 does not protrude out of the groove 4322, thus avoiding collision with external objects.

[0042] Reference Figure 2 , Figure 4 and Figure 7 As shown, in some embodiments, the cathode mounting bracket 300 includes a first inner peripheral wall 330 and a second inner peripheral wall 340. The end of the cylindrical portion 410 away from the connecting seat 430 abuts against the first inner peripheral wall 330. The first inner peripheral wall 330 also abuts against the end face of the shielding sleeve 500 away from the connecting seat 430, thereby restricting the free movement of the shielding sleeve 500 along the axial direction of the X-ray tube 200 and preventing the shielding sleeve 500 from detaching from the X-ray tube 200. The second inner peripheral wall 340 abuts against the outer peripheral wall of the cylindrical portion 410. It can be understood that the second inner peripheral wall 340 is sleeved on the outer periphery of the cylindrical portion 410 and plays a limiting role on the cylindrical portion 410.

[0043] Reference Figure 2 and Figure 5As shown, in some embodiments, the X-ray tube assembly 1000 further includes a shielding sleeve 500, which is used to shield X-rays. The shielding sleeve 500 may be made of lead material. The shielding sleeve 500 is fitted around the outer periphery of the cylindrical portion 410. The outer peripheral wall of the shielding sleeve 500 is provided with a second clearance opening 510 for avoiding the first light outlet 210. The outer periphery of the cylindrical portion 410 is provided with an annular portion 420, which extends circumferentially along the cylindrical portion 410. An annular groove 421 is formed between the annular portion 420 and the cylindrical portion 410. Part of the structure of the shielding sleeve 500 is inserted into the annular groove 421, which can limit the shielding sleeve 500.
