[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] As Figure 1 、 Figure 2 shown, the tube housing 100 claimed in the present application is applied to the X-ray tube 1000 and is used to wrap the tube assembly 200 of the X-ray tube 1000.

[0041] AsFigures 1 to 4 As shown in Figures 1 to 4 , the tube housing 100 provided by an embodiment of the present application includes an upper cover 10 of the tube housing and a lower cover 20 of the tube housing. The lower cover 20 of the tube housing is disposed below the upper cover 10 of the tube housing in the vertical direction, and the lower cover 20 of the tube housing is connected to the upper cover 10 of the tube housing. Moreover, a sealed chamber 101 can be formed by enclosing between the lower cover 20 of the tube housing and the upper cover 10 of the tube housing, and the sealed chamber 101 is used to house the tube assembly 200. That is to say, the tube housing 100 of the present application is formed by connecting the upper cover 10 of the tube housing and the lower cover 20 of the tube housing which are arranged up and down.

[0042] It can be understood that since the tube housing 100 of the present application is formed by connecting the upper cover 10 of the tube housing and the lower cover 20 of the tube housing which are arranged up and down in the vertical direction, the parting line 102 formed by the connection between the upper cover 10 of the tube housing and the lower cover 20 of the tube housing is arranged on the peripheral side of the tube housing 100. In this way, the overall waterproof effect of the tube housing 100 can be improved to prevent water droplets, blood droplets, etc. from entering the inside of the tube housing 100, and the external aesthetics can be improved. At the same time, the tube housing 100 can be opened by separately removing the upper cover 10 of the tube housing, which is convenient for subsequent maintenance of the tube assembly 200 inside the tube housing 100.

[0043] It should be noted that external substances such as water and blood can only enter through the parting line 102 between the upper cover 10 of the tube housing and the lower cover 20 of the tube housing on the tube housing 100. And the parting line 102 of the tube housing 100 is arranged on the peripheral side of the tube housing 100. The water, blood, etc. located on the peripheral side of the tube housing 100 will flow downward under the action of gravity and will not stay, making it difficult for substances such as water and blood to enter the inside of the tube housing 100 through the parting line 102, so that the tube housing 100 has a good waterproof effect.

[0044] Such as Figure 1 、 Figure 5As shown, in one embodiment, a sub - part line 102 is formed and connected between the upper cover 10 of the tube housing and the lower cover 20 of the tube housing; among them, the sub - part line 102 is arranged at the bottom position of the tube housing 100, or / and, the sub - part line 102 is arranged on the circumferential side of the tube housing 100. This can well hide the sub - part line 102 on the tube housing 100, which can further improve the external aesthetics of the tube housing 100. Here, the sub - part line 102 is a dividing line formed on the outer peripheral surface of the tube housing 100 after the lower cover 20 of the tube housing is connected to the upper cover 10 of the tube housing. The position of the sub - part line 102 on the tube housing 100 of the present application can be controlled by controlling the height of the lower cover 20 of the tube housing in the vertical direction; among them, the above - mentioned bottom position of the tube housing 100 specifically refers to the position below the middle of the tube housing 100 in the vertical direction. Of course, in other embodiments, the sub - part line 102 of the tube housing 100 can also be arranged at other positions in the vertical direction of the tube housing 100.

[0045] As Figure 5 shown, in one embodiment, a plug - in part 210 is formed on the lower cover 20 of the tube housing, and a plug - in mating part 110 is formed on the upper cover 10 of the tube housing. The plug - in part 210 can be plugged and mated with the plug - in mating part 110. That is to say, the upper cover 10 of the tube housing and the lower cover 20 of the tube housing are assembled in a plug - in mating manner. In this way, it is convenient for the assembly between the upper cover 10 of the tube housing and the lower cover 20 of the tube housing, and ensures the accuracy of the positions of the two after assembly. Here, the upper cover 10 of the tube housing can be plugged and mated with the lower cover 20 of the tube housing downward in the vertical direction.

[0046] As Figure 5 shown, the plug - in part 210 is configured as a rib 211 formed on the lower cover 20 of the tube housing, and the plug - in mating part 110 is configured as a slot 111 opened on the upper cover 10 of the tube housing. And when the rib 211 is plugged and mated with the slot 111, the slot wall 1111 of the slot 111 can wrap the rib 211, which can further improve the waterproof effect after the assembly between the upper cover 10 of the tube housing and the lower cover 20 of the tube housing. Here, the slot 111 on the upper cover 10 of the tube housing is arranged at one end of the upper cover 10 of the tube housing facing the lower cover 20 of the tube housing in the vertical direction, which can better hide the sub - part line 102 formed by the connection between the upper cover 10 of the tube housing and the lower cover 20 of the tube housing. Of course, in other embodiments, the plug - in part 210 can also be configured as a slot opened on the lower cover 20 of the tube housing, and the plug - in mating part 110 can be configured as a rib formed on the upper cover 10 of the tube housing, which will not be elaborated here.

[0047] As Figure 1 、 Figure 3As shown, in one embodiment, the tube housing 100 further includes a fixing member 30. The upper cover 10 of the tube housing can be detachably connected to the lower cover 20 of the tube housing through the fixing member 30, and the detachable connection between the upper cover 10 and the lower cover 20 of the tube housing is realized, so that it is convenient to remove the upper cover 10 of the tube housing from the lower cover 20 subsequently. Here, the fixing member 30 can pass through the lower cover 20 of the tube housing and be threadedly connected to the upper cover 10 of the tube housing. Specifically, the fixing member 30 can be configured as a bolt, a screw, etc. It should be noted that the lower cover 20 and the upper cover 10 of the tube housing can be connected and fixed by a plurality of fixing members 30 arranged in sequence on both sides of the lower cover 20 of the tube housing.

[0048] As Figure 2 、 Figure 3 As shown, in one embodiment, the lower cover 20 of the tube housing is configured as a split structure. Of course, in other embodiments, the lower cover 20 of the tube housing is configured as an integral structure. Here, the lower cover 20 of the tube housing is specifically a plastic part, and can be specifically prepared by injection molding using a mold. The lower cover 20 of the tube housing is configured as a split structure mainly due to the complexity of the overall structure of the lower cover 20 of the tube housing.

[0049] As Figure 3 As shown, in one embodiment, the lower cover 20 of the tube housing includes a first lower sub-cover 21 and a second lower sub-cover 22. The second lower sub-cover 22 is independently arranged relative to the first lower sub-cover 21, and the second lower sub-cover 22 can abut against the first lower sub-cover 21 and be connected to the first lower sub-cover 21. That is to say, the lower cover 20 of the tube housing in this embodiment is formed by connecting the split first lower sub-cover 21 and the second lower sub-cover 22. In this way, the first lower sub-cover 21 and the second lower sub-cover 22 can be separately prepared by molds and then the prepared first lower sub-cover 21 and the second lower sub-cover 22 are connected. Thus, it is convenient for the production and preparation of the lower cover 20 of the tube housing. Here, the first lower sub-cover 21 and the second lower sub-cover 22 can be specifically connected by screws 103. It should be noted that since the lower cover 20 of the tube housing is formed by connecting the first lower sub-cover 21 and the second lower sub-cover 22, the structures of the first lower sub-cover 21 and the second lower sub-cover 22 are simpler than the structure of the lower cover 20 of the tube housing. In this way, it is convenient for the structural design of the molds used to prepare the first lower sub-cover 21 and the second lower sub-cover 22, and thus it is convenient for the production and preparation of the lower cover 20 of the tube housing.

[0050] As Figure 3 As shown, in one embodiment, the first lower sub-cover 21 and the second lower sub-cover 22 are configured with the same structure, so that the first lower sub-cover 21 and the second lower sub-cover 22 can share a set of molds. Thus, it is further convenient for the production and preparation of the lower cover 20 of the tube housing and has the effect of reducing costs.

[0051] As Figure 2 , Figure 3 and Figure 5 shown, in one embodiment, the tube housing 100 further includes a sealing strip 40. The sealing strip 40 is disposed between the lower cover 20 and the upper cover 10 of the tube housing, and is used for assembling and sealing the upper cover 10 and the lower cover 20 of the tube housing. Thus, the overall waterproof effect of the tube housing 100 can be further improved. Here, the sealing strip 40 is disposed at the bottom of the slot 111 on the upper cover 10 of the tube housing, so that the slot 111 on the upper cover 10 of the tube housing can be used to limit the assembly of the sealing strip 40 and facilitate the assembly of the sealing strip 40; and, the sealing strip 40 can undergo elastic deformation under the extrusion of the rib 211 on the lower cover 20 of the tube housing.

[0052] As Figure 6 , Figure 7 shown, the present application further provides an X-ray tube 1000, including a tube assembly 200 and the above-mentioned tube housing 100. At least a part of the tube assembly 200 is received in the closed chamber 101 of the tube housing 100.

[0053] As Figure 6 , Figure 7 shown, the present application further provides an C-arm device 2000, including the above-mentioned X-ray tube 1000.

[0054] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0055] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as appropriate changes and variations made to the above embodiments fall within the spirit and scope of the present invention, they fall within the scope of protection required by the present invention.
