Description

Technical Field

[0001] This utility model relates to the field of X-ray tube technology, specifically to a high-heat-capacity X-ray tube. Background Technology

[0002] High heat capacity X-ray tubes are a special type of X-ray tube designed to continuously output high-intensity X-rays for a short period of time while maintaining good stability and a long service life.

[0003] Chinese utility model patent CN220272414U discloses a high-heat-capacity X-ray tube, relating to the field of X-ray tube technology. It includes a metal casing, with an anode ceramic disposed on one side of the metal casing, and an anode heat-conducting metal disposed on the other side of the anode ceramic. An exhaust port is fixedly disposed on the other side of the metal casing, and a sleeve is movably disposed at one end of the exhaust port. A dustproof mesh is movably disposed inside the sleeve. A first connecting plate is fixedly disposed on the outer wall of the exhaust port, and a second connecting plate is fixedly disposed on the outer wall of the sleeve. The first and second connecting plates are movably connected. By using the dustproof mesh, dust from the external environment can be blocked, preventing dust from entering the interior of the high-heat-capacity X-ray tube through the exhaust port and damaging the internal components, thus protecting the X-ray tube.

[0004] In existing technologies, filter sleeves rely on simple threaded connections or other fixing methods, making them prone to loosening or detachment during use, especially under high temperature, high pressure, or vibration environments. The lack of an effective cushioning mechanism makes the filter sleeves susceptible to damage from hard impacts during installation or use. The disassembly and installation processes of existing filter sleeves are relatively complex, requiring tools or complicated operations, increasing maintenance costs and time. The inconvenience of replacing or cleaning the filter screen leads to decreased filtration efficiency and affects the normal operation of the equipment. Therefore, a high-heat-capacity X-ray tube is needed to solve these problems. Utility Model Content

[0007] Furthermore, each of the two slide bar groups consists of four slide bars, and each of the two slide plates has a groove near the four corners. The four slide bars in a group are movably connected to the grooves on the two slide plates, and rubber blocks are fixedly installed on the outer surface of the four slide bars near the left and right sides.

[0008] Furthermore, the ends of the two blocks away from the two slide plates pass through the interior of the two placement slots and extend into the interior of the exhaust end. In use, the ends of the blocks away from the slide plates are movably engaged with the interior of the two slots.

[0009] Furthermore, the ends of the two springs away from the slide plate are respectively fixedly connected to the inner walls of the two placement slots.

[0010] Furthermore, a connection port is provided at the bottom of the exhaust end, and the exhaust end communicates with the interior of the metal casing.

[0013] Beneficial effects:

[0014] 1. This high-heat-capacity X-ray tube, through the design of a slot, slide plate, spring, rubber block, connection port, locking block, placement groove, and sliding rod assembly, ensures that the filter sleeve is firmly fixed to the exhaust end, preventing loosening or detachment during use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model discloses a high heat capacity X-ray tube, including a metal shell 2, an anode heat-conducting metal 1 fixedly installed at the bottom of the metal shell 2, an anode shell 3 fixedly installed at the top of the metal shell 2 near the left side, an exhaust end 5 at the top of the metal shell 2 near the right side, a filter sleeve 4 is provided on the exhaust end 5, and slots 6 are opened on the left and right sides of the outer surface of the filter sleeve 4 near the center. Placement grooves 12 are opened on the left and right side walls of the exhaust end 5 near the center. Slide rod groups 13 are provided inside the two placement grooves 12, and slide plates 7 are provided on the two slide rod groups 13. Springs 8 are fixedly installed on opposite sides of the two slide plates 7, and locking blocks 11 are fixedly installed on adjacent sides of the two slide plates 7.

[0021] Specifically, each of the two slide bar groups 13 consists of four slide bars, and each of the two slide plates 7 has a groove near the four corners. The four slide bars are movably connected to the grooves on the two slide plates 7, and rubber blocks 9 are fixedly installed on the outer surface of the four slide bars near the left and right sides.

[0022] Specifically, the ends of the two locking blocks 11 that are away from the two sliding plates 7 pass through the interior of the two placement slots 12 and extend into the interior of the exhaust end 5. In use, the ends of the locking blocks 11 that are away from the sliding plates 7 are respectively engaged with the interior of the two locking slots 6.

[0023] Specifically, the ends of the two springs 8 that are away from the slide plate 7 are respectively fixedly connected to the inner walls of the two placement slots 12.

[0024] Specifically, the bottom of the exhaust end 5 is provided with a connection port 10, and the exhaust end 5 is connected to the interior of the metal casing 2.

[0025] Specifically, a filter screen is installed at the top of the filter sleeve 4.

[0026] During use, the outer surface of the filter sleeve 4, near its bottom, is threadedly connected to the inner wall of the exhaust end 5. During installation, the operator needs to rotate the filter sleeve 4 to gradually tighten it into the exhaust end 5. As the filter sleeve 4 rotates, its outer surface begins to contact the internal structure of the exhaust end 5. This tight contact not only increases the connection strength but also provides the necessary pressure conditions for the subsequent action of the locking block 11. During the rotation and tightening of the filter sleeve 4, an interesting phenomenon occurs: the locking block 11, due to the pressure from the outer surface of the filter sleeve 4, opens... The filter sleeve 4 gradually retracts into the placement groove 12; this action causes the slide plate 7 to move inward along the slide rod assembly 13 and the spring 8, thus compressing the spring 8 and storing elastic potential energy; this setting cleverly utilizes the elastic characteristics of the spring 8, enabling the entire connection structure to have a certain buffering and self-adaptive ability when subjected to force; even if there are minor errors or uneven force during installation, the elasticity of the spring 8 can ensure that the locking block 11 can retract smoothly, avoiding damage to components due to hard collisions; as the filter sleeve 4 continues to rotate, until the inside of the locking groove 6 on its outer surface contacts the exhaust... When the outer surface of the locking block 11 on end 5 is reached, the pressing force on the spring 8 gradually disappears; at this time, the spring 8 is released and quickly returns to its original shape, and its strong restoring force pushes the locking block 11 into the slot 6; this action not only ensures a firm connection between the filter sleeve 4 and the exhaust end 5, but also further enhances the connection strength between the two; once the locking block 11 is fully engaged in the slot 6, the filter sleeve 4 is firmly fixed on the exhaust end 5; at this time, the entire high heat capacity X-ray tube forms a stable and reliable connection structure; this setting not only ensures the stability of the filter sleeve 4 during use. This design not only improves the reliability and lifespan of the high-heat-capacity X-ray tube, but also facilitates subsequent disassembly and maintenance. When the filter sleeve 4 needs to be replaced or cleaned, simply rotate the filter sleeve 4 in the reverse direction, and the locking block 11 will automatically disengage from the slot 6 under the action of the spring 8, thus easily achieving disassembly. This not only improves the reliability and lifespan of the high-heat-capacity X-ray tube, but also brings a convenient operating experience to the user. The filter sleeve 4 can be installed and disassembled through a simple rotation action, greatly reducing maintenance costs and operating difficulty. At the same time, the buffering effect of the spring 8 also reduces wear between components, further extending the lifespan of the high-heat-capacity X-ray tube.

[0027] In summary, this high-heat-capacity X-ray tube, through the arrangement of slot 6, slide plate 7, spring 8, rubber block 9, connection port 10, locking block 11, placement groove 12, and sliding rod assembly 13, ensures that the filter sleeve 4 is firmly fixed to the exhaust end 5 by the cooperation of slot 6 and locking block 11, preventing it from loosening or falling off during use. The elastic restoring force of spring 8 can push locking block 11 tightly into slot 6, further enhancing the connection strength between filter sleeve 4 and exhaust end 5. The connection or disassembly of filter sleeve 4 to exhaust end 5 can be achieved by rotating it, making the operation simple and quick. This arrangement facilitates regular replacement or cleaning of the filter screen, ensuring filtration effect while reducing maintenance time and costs. The elastic characteristics of spring 8 can absorb minor errors or uneven forces during installation, reducing hard collisions between components and thus extending the service life of the high-heat-capacity X-ray tube. The sliding rod assembly 13 and sliding groove ensure the smooth movement of locking block 11 and slide plate 7, and the use of rubber block 9 further reduces wear between components.
