Description
Technical field
The utility model relates to a kind of breast X-ray pipe.
Background technology
Year history surplus the breast X-ray pipe is applied to clinical existing 50, technical performance and clinical practice are all ripe.The structure of existing breast X-ray pipe is as follows: comprise the shell of being made up of front end housing, cylindrical shell and rear end cap, be provided with X ray naked pipe assembly and rotarting anode motor stator in the enclosure, be respectively equipped with high-tension connector, low voltage connector and fuel filler neck on shell; X ray naked pipe assembly is the critical piece in the breast X-ray pipe, this X ray naked pipe assembly comprises metal X ray naked pipe housing (hereinafter to be referred as metal naked pipe shell), in metal naked pipe shell, be respectively equipped with rotarting anode and filament (this filament is as negative electrode), the outer surface of anode set bolt and metal naked pipe shell is fixedly linked, and anode set bolt and rotarting anode electrically connect; On metal naked pipe shell, be respectively equipped with vacuum pumping port and X ray exit window, be arranged in the beryllium sheet of X ray exit window inner chamber and the inner surface of X ray exit window and be fixedly linked hermetically; On shell, be provided with and the corresponding outer casing through hole of X ray exit window, the X ray exit window passes outer casing through hole, because metal naked pipe shell is made of metal, promptly metal naked pipe shell has enough installation strength, so the outer surface of X ray exit window and outer casing through hole are fixedly linked hermetically.High-tension connector and anode set bolt electrically connect, and low voltage connector and rotarting anode motor stator and filament electrically connect.
During actual production, by vacuum pumping port whole X ray naked pipe assembly being vacuumized processing, then vacuum pumping port is made encapsulation process, is vacuum state thereby make the inner chamber of whole X ray naked pipe assembly.In the inner chamber of shell, pour into insulating oil by fuel filler neck, so be full of insulating oil between the inner surface of shell and the metal naked pipe shell.Feed suitable low-tension supply by low voltage connector, rotarting anode is started, also give filament pre-heating simultaneously.1.2S after, feed suitable high-tension electricity through high-tension connector to rotarting anode again, just can penetrate X ray from the beryllium sheet.
Above-mentioned existing breast X-ray pipe exists following defective, because metal naked pipe shell adopts metal to make, therefore production cost is very high, causes the breast X-ray pipe of the unable purchase value of some small medical mechanisms costliness, thereby can't carry out effective diagnosis to mammary gland disease.
In order to reduce production costs, the X ray naked pipe housing that people also attempt to utilize glass to make comes alternative metals naked pipe shell.But but run into a following difficult problem in the actual installation production process:
1), since glass intensity well below metal, iff relying on single-point ways of connecting (outer surface of X ray exit window for example of the prior art is fixedly linked with outer casing through hole) is effective the linking to each other that can't realize between X ray naked pipe housing and the shell, if 2 place's fixed connection points are set on X ray naked pipe housing, so in the fastening process of the 2nd tie point, under the effect of stress, the X ray naked pipe housing that glass is made is easy to take place broken.
2), because the rising-heat contracting-cold of insulating oil in the practical work process, be insulated the X ray naked pipe housing that glass that oil surrounded makes and also be easy to take place broken.
3), because whole X ray naked pipe housing is made by glass, so the outer surface of X ray exit window and outer casing through hole (material is a metal) be difficult to realize sealing link to each other, thereby cause the leakage of insulating oil.
The utility model content
The technical problems to be solved in the utility model provides a kind of with low cost, breast X-ray pipe that practical effect is good.
In order to solve the problems of the technologies described above, the utility model provides a kind of breast X-ray pipe, comprises shell, is provided with X ray naked pipe assembly and rotarting anode motor stator in the enclosure, is respectively equipped with high-tension connector, low voltage connector and fuel filler neck on shell; X ray naked pipe assembly comprises X ray naked pipe housing, in X ray naked pipe housing, be provided with rotarting anode and filament, be provided with vacuum pumping port and X ray exit window on X ray naked pipe housing, the outer surface of anode set bolt and X ray naked pipe housing is fixedly linked and anode set bolt and rotarting anode electrically connect; On shell, be provided with and the corresponding outer casing through hole of X ray exit window; This X ray naked pipe housing is the housing that glass is made, the X ray exit window links to each other with the sealing of beryllium sheet by cutting down connector, the trumpet type sealing ring that oil resistant rubber is made is set can cutting down between connector and the outer casing through hole, can cuts down the inner chamber that connector and beryllium sheet all are arranged in the trumpet type sealing ring.
Improvement as breast X-ray pipe of the present utility model: be provided with the rubber harmomegathus device that is fixedly linked with body seal in the enclosure, the opening of rubber harmomegathus device communicates with the outer surface of shell.
Further improvement as breast X-ray pipe of the present utility model: be respectively equipped with anode fixed support and negative electrode fixed support in the enclosure, anode set bolt and anode fixed support are fixedly linked, X ray naked pipe housing is sleeved in the negative electrode fixed support, between the outer surface of negative electrode fixed support and X ray naked pipe housing cushion block is set.
Further improvement as breast X-ray pipe of the present utility model: rubber harmomegathus device is half-moon-shaped rubber harmomegathus device.
Breast X-ray pipe of the present utility model because X ray naked pipe housing adopts glass to make, therefore can reduce production costs.Breast X-ray pipe of the present utility model is provided with the anode fixed support in the enclosure, and anode set bolt and anode fixed support that utilization and X ray naked pipe housing are fixedly linked are fixedly linked, thereby realize effective connection the between X ray naked pipe assembly and the shell, avoided directly being fixedly linked of X ray naked pipe housing and shell, thereby avoided that X ray naked pipe housing breaks in installation process.This breast X-ray pipe also is provided with the negative electrode fixed support in the enclosure, and between the outer surface of the X ray naked pipe housing in being set in the negative electrode fixed support and the negative electrode fixed support cushion block is set, therefore this negative electrode fixed support plays the effect of supporting this X ray naked pipe assembly, and cushion block also plays the effect of damping.In work during insulating oil generation rising-heat contracting-cold, because the flexibility of rubber is far longer than glass, therefore the rubber harmomegathus device that is immersed in the insulating oil can produce corresponding distortion along with insulating oil, thereby the X ray naked pipe housing of avoiding glass to make is subjected to the effect of rising-heat contracting-cold power, therefore can guarantee that fragmentation does not take place X ray naked pipe housing.
