Abstract
Description
Technical Field
[0001] This utility model relates to the field of X-ray tube device technology, and in particular to an X-ray tube with re-venting capability. Background Technology
[0002] X-ray tubes require a specific vacuum and high-pressure environment to function properly. To ensure this vacuum environment, the tube needs to be evacuated and then sealed to maintain a specific vacuum level. However, in existing manufacturing processes, the exhaust port is typically completely sealed after the X-ray tube is evacuated, making it impossible to evacuate and vent the tube again after sealing. In actual use, quality control often necessitates reopening the tube for leak testing. To avoid wasting resources after leak testing, a relatively cumbersome process is required to evacuate and reseal the tube again, which can easily damage or contaminate the tube, affecting its quality. Therefore, this application proposes a re-evacuated X-ray tube to avoid these problems. Utility Model Content
[0003] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a reusable exhaust X-ray tube. The solution includes a waist clamp with a positive and negative end fixedly mounted at its upper and lower ends. The waist clamp contains a vacuum chamber. An exhaust pipe is fixedly connected to the upper end of the waist clamp. The other end of the exhaust pipe is fixedly connected to the right end of a connector tube. A metal flexible tube is fixedly connected to the left end of the connector tube. A sealing tube is integrally formed through the middle of the connector tube. A piston rod is coaxially and slidably connected to the sealing tube. A mounting plate is coaxially and fixedly connected to the bottom of the piston rod. A sealing plug that slides against the inner wall of the sealing tube is coaxially and fixedly connected to the mounting plate. The sealing plug is used to seal the connector tube. A guide rod is fixedly connected to the upper end of the sealing tube. A support plate is fixedly connected to the upper end of the guide rod. A driving device is connected to the support plate. The driving device drives a vertical moving rod slidably connected to the guide rod. The vertical moving rod is fixedly connected to the piston rod.
[0004] Preferably, the driving device includes a driving screw that is rotatably connected to the upper part of the support rod, the lower end of the driving screw being rotatably connected to the top of the encapsulation tube, and the driving screw being threadedly connected to one end of the vertical moving rod.
[0005] Preferably, a dial is coaxially fixedly connected to the upper end of the drive screw.
[0006] Preferably, one end of the vertical moving rod is fixedly connected to a guide sleeve that is slidably connected to the guide rod, and the other end of the vertical moving rod is fixedly connected to a threaded sleeve that is threadedly connected to the drive screw.
[0007] The beneficial effects of this utility model are: In use, the free end of the metal hose is connected to a vacuum pump (not shown in the diagram), allowing for the exhaust of the vacuum chamber to create a vacuum environment. To enable repeated exhaust, a connector tube is included, with an integrally formed sealing tube. After exhaust, a drive mechanism moves the vertical rod downwards, causing the piston rod to move downwards along the sealing tube. Simultaneously, the mounting plate and sealing plug move downwards, sealing the connector tube and maintaining the vacuum level. To remove the seal for quality inspection, the drive mechanism moves the piston rod and sealing plug upwards, releasing the seal. When exhaust is required again after inspection, the metal hose is reconnected to the vacuum pump. This invention features a simple structure, ease of use, and high practicality. It allows for convenient and repeated sealing and disassembly of the connector tube via the sealing plug, facilitating quick and efficient repeated exhaust and sealing while avoiding damage and contamination to the X-ray tube.

[0014] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.
[0015] In the first embodiment, the technical solution is as follows: When in use, the free end of the metal hose 6 is connected to a vacuum pump (not shown in this application; the specific connection method can be achieved using existing technology, and will not be described in detail here). This allows for the exhaust of the vacuum chamber 3 to create a certain vacuum environment. Furthermore, to enable repeated exhaust, a connector tube 5 is provided, and a sealing tube 7 is integrally formed on the connector tube 5. After exhaust is completed, the vertical moving rod 13 can be moved downwards by the driving device, which in turn moves the piston rod 8 downwards along the sealing tube 7. Consequently, the mounting plate 9, along with the sealing plug 10, will also move downwards synchronously. The sealing plug 10 can then seal the connector tube 5, maintaining the vacuum level in the vacuum chamber 3. When the seal needs to be removed for quality inspection, the piston rod 8, along with the sealing plug 10 and other components, can be moved upwards by the driving device to release the seal on the connector tube 5. When the quality inspection is completed and exhaust is required again, the metal hose 6 can be reconnected to the vacuum pump. This application has a simple structure, is easy to use, and is highly practical. It can easily achieve repeated sealing and separation by sealing the joint tube 5 with the sealing plug 10, thereby facilitating quick and efficient repeated venting and sealing. Moreover, compared with the traditional operation method, this application does not require excessive contact and operation with the X-ray tube, thus avoiding damage and contamination to the X-ray tube.
[0016] In Example 2, based on Example 1, in this application, the waist clamp 1 is specifically divided into a male end 2 and a female end 18 at its upper and lower ends to facilitate wiring connections. The free end of the metal hose 6 can be connected to the vacuum pump using existing technology. When venting and evacuating the vacuum chamber 3 inside the clamp, the piston is first moved by the drive device to prevent it from blocking the connector pipe 5. Specifically, the drive screw 14 is rotated clockwise. To facilitate the rotation of the drive screw 14, a dial 15 is provided. The clockwise rotation of the drive screw 14 will act on the vertical moving rod 13 through the threaded sleeve 17, and the vertical moving rod 13 will then act on the guide... The sleeve 16 is slidably connected to the guide rod 11. Therefore, the clockwise rotation of the drive screw 14 will drive the vertical moving rod 13 to move upward along the guide rod 11. Consequently, the piston rod 8, which is fixedly connected to the vertical moving rod 13, will slide upward along the encapsulation tube 7. As the piston rod 8 slides upward along the encapsulation tube 7, the mounting plate 9, which is fixedly connected to the piston rod 8, and the sealing plug 10, which is fixedly connected to the mounting plate 9, will also move upward. This will allow the sealing plug 10 to completely detach from the sealing of the connector tube 5, ensuring the unobstructed flow of the connector tube 5. Thus, the vacuum pump can exhaust and evacuate the vacuum chamber 3 through the metal hose 6, the connector tube 5, and the exhaust pipe 4.
[0017] After exhausting and vacuuming are completed, the drive screw 14 of the drive device is rotated counterclockwise. The drive screw 14 will drive the vertical moving rod 13 to move downward along the guide rod 11. The piston rod 8, which is fixedly connected to the vertical moving rod 13, will also move downward. At the same time, the mounting plate 9 and the sealing plug 10 and other related components will also move downward, so that the sealing plug 10 can be inserted into the connector tube 5 to seal the connector tube 5, thus completing the sealing operation after exhausting.
[0018] In Example 3, based on Example 2, the drive screw 14 is rotatably connected between the encapsulation tube 7 and the support plate 12, and a dial 15 is provided at the upper end to facilitate the rotation of the drive screw 14 through the dial 15.
