[0034] Reference Figures 1 to 4 , an embodiment of the present invention provides a pipeline structure 100, including a first pipe body 10, a second pipe body 20, a locking sleeve 30, a locking tongue device 40 and a locking device 50.

[0035] Among them, the first tube body 10 and the second tube body 20 are hard pipes, both used to pass cooling water, and the second tube body 20 and the first tube body 10 are detachably connected; the locking sleeve 30 is respectively sleeved on one end of the first tube body 10 and one end of the second tube body 20, and is respectively rotatably arranged with the first tube body 10 and the second tube body 20; the locking tongue device 40 is connected to the first tube body 10; the locking device 50 is connected to the second tube body 20, and can be locked or unlocked with the locking tongue device 40, so that in the unlocked state, the locking sleeve 30 can be rotated relative to the first tube body 10 and / or the second tube body 20 to achieve separation from the first tube body 10, or the second tube body 20, and in the locked state, the first tube body 10 and the second tube body 20 are respectively locked with the locking sleeve 30.

[0036] The above-mentioned pipeline structure 100, the first tube body 10 and the second tube body 20 are used for circulating water. When the first tube body 10 and the second tube body 20 are connected or separated, since the locking tongue device 40 is installed outside the first tube body 10 and the locking device 50 is installed outside the second tube body 20, after the locking device 50 is locked or unlocked relative to the locking tongue device 40, the first tube body 10 and the second tube body 20 can be driven to rotate relative to the locking sleeve 30 respectively, so that the connection or separation between the first tube body 10 and the second tube body 20 can be quickly realized, the disassembly and assembly operation is convenient, and the efficiency of workers is improved.

[0037] Among them, see Figure 4 Since water needs to flow through the first tube body 10 and the second tube body 20, in order to prevent water from overflowing out of the tube body, when the first tube body 10 and the second tube body 20 are respectively locked with the locking sleeve 30, the first tube body 10 is sleeved outside the second tube body 20. At this time, the walls between the first tube body 10 and the second tube body 20 are in contact with each other, which can prevent water from overflowing from the ports of the first tube body 10 or the second tube body 20. Specifically, when the first tube body 10 is sleeved outside the second tube body 20 in this embodiment, the two are plugged together, thereby achieving high installation efficiency; in other embodiments, the two can be connected by threading to ensure stability and tightness of the connection.

[0038] Further, see Figure 2 and Figure 4 To further enhance the tightness of the two after they are respectively connected to the locking sleeve 30, the pipe structure 100 also includes a sealing ring 60. The sealing ring 60 is disposed outside the second pipe body 20 and abuts against the inner wall of the first pipe body 10. In this way, by providing the sealing ring 60, it can abut against the inner wall of the first pipe body 10 and the outer wall of the second pipe body 20 respectively. The sealing ring 60 is compressed between the first pipe body 10 and the second pipe body 20, which can block the water flow and prevent the water from overflowing from the pipe opening of the pipe body. In other embodiments, the sealing ring 60 can be provided on the inner wall of the first pipe body 10, which can also achieve the effect of sealing between the first pipe body 10 and the second pipe body 20.

[0039] See also Figure 2 and Figure 4In order to facilitate the installation of the sealing ring 60 on the second tube body 20, a card groove 23 is provided on the outer wall of the second tube body 20, and the sealing ring 60 is clamped in the card groove 23. That is, the installation of the sealing ring 60 is limited by the setting of the card groove 23, which prevents the sealing ring 60 from being pushed and moved during the plug-in connection process of the first tube body 10 and the second tube body 20, thereby affecting the socket connection between the first tube body 10 and the second tube body 20; further, the setting of the card groove 23 also determines the installation position of the sealing ring 60 on the second tube body 20, which facilitates the quick installation of the sealing ring 60.

[0040] It can be understood that since the sealing ring 60 needs to be held between the first tube body 10 and the second tube body 20, the sealing ring 60 is partially clamped in the clamping groove 23 and partially protrudes from the second tube body 20, that is, the depth of the clamping groove 23 along the radial direction of the second tube body 20 is less than the thickness of the sealing ring 60, so as to achieve the effect of the sealing ring 60 protruding from the second tube body 20.

[0041] The locking sleeve 30 is sleeved on the outside of the first tube body 10 and the second tube body 20 and is rotatable relative to the first tube body 10 and the second tube body 20. For example, the locking sleeve 30 can be detachably connected to the first tube body 10 and the second tube body 20 by threaded connection. Figures 2 to 4 , which are the matching modes of the locking sleeve 30 and the first tube body 10 and the second tube body 20 respectively in this embodiment.

[0042] The locking sleeve 30 has a plurality of first protrusions 31 disposed circumferentially on the inner wall of one end facing the first tube 10, and the plurality of first protrusions 31 are disposed at intervals. The locking sleeve 30 has a plurality of second protrusions 32 disposed circumferentially on the inner wall of the other end facing the second tube 20, and the plurality of second protrusions 32 are disposed at intervals.

[0043] A plurality of third protrusions 11 are provided on the outer wall of the first tube body 10 along the circumferential direction. The plurality of third protrusions 11 are arranged at intervals. The third protrusions 11 and the first protrusions 31 can overlap or stagger with each other to achieve installation or separation of the first tube body 10 and the locking sleeve 30.

[0044] A plurality of fourth protrusions 21 are provided on the outer wall of the second tube body 20 along the circumferential direction. The plurality of fourth protrusions 21 are arranged at intervals. The fourth protrusions 21 and the second protrusions 32 can overlap or stagger to achieve the installation or separation of the second tube body 20 and the locking sleeve 30. That is, there is a first avoidance opening 12 between the third protrusions 11, and there is a second avoidance opening 22 between the fourth protrusions 21. When the locking sleeve 30 is installed on the first tube body 10 and the second tube body 20 respectively, the first protrusion 31 is inserted into the first avoidance opening 12, and the first tube body 10 or the locking sleeve 30 is rotated so that the first protrusion 31 and the third protrusion 11 overlap; similarly, the second The protrusion 32 is inserted into the corresponding second avoidance opening 22, and the second tube body 20 or the locking sleeve 30 is rotated so that the second protrusion 32 and the fourth protrusion 21 overlap, and then the locking device 50 and the locking tongue device 40 are locked, so that the locking between the first tube body 10 and the second tube body 20 can be achieved; when disassembling, the locking device 50 and the locking tongue device 40 are unlocked, and the locking sleeve 30 is rotated so that the first protrusion 31 and the third protrusion 11 are staggered, and the first tube body 10 is detached; or the second protrusion 32 and the fourth protrusion 21 are staggered, and the second tube body 20 is detached, both of which can achieve the disassembly between the first tube body 10 and the second tube body 20, and the operation is quick.

[0045] Furthermore, to prevent the first tube 10 or the second tube 20 from entering from one end of the locking sleeve 30 and then exiting from the other end of the locking sleeve 30 when the first tube 10 and the locking sleeve 30 or the second tube 20 and the locking sleeve 30 are installed, the circumferential extension length of the third protrusion 11 along the first tube 10 is greater than the circumferential extension length of the fourth protrusion 21 along the circumferential extension length of the second tube 20. That is, correspondingly, the circumferential extension length of the first protrusion 31 along the circumferential extension length of the locking sleeve 30 is greater than the circumferential extension length of the second protrusion 32 along the circumferential extension length of the locking sleeve 30. Furthermore, the number of the first protrusion 31 and the second protrusion 32 is different. For example, when the second tube 20 extends from one end of the locking sleeve 30, due to the different lengths of the protrusions at both ends of the locking sleeve 30, the first protrusion 31 blocks the fourth protrusion 21, thereby preventing the second tube 20 from exiting from the other end of the locking sleeve 30, thereby improving the installation convenience of each tube body and the locking sleeve 30.

[0046] Further, see Figure 4 In order to ensure the stability of the first tube body 10 and the second tube body 20 after installation, when the first tube body 10 and the second tube body 20 are respectively locked with the locking sleeve 30, the first tube body 10 and the second tube body 20 are abutted against each other, that is, the third protrusion 11 and the fourth protrusion 21 are abutted against each other, exerting a force on each other, thereby ensuring stability after installation with the locking sleeve 30.

[0047] See also Figure 1 and Figure 2, is a schematic structural diagram of the locking tongue device 40 of this embodiment. The locking tongue device 40 includes a ring body 41 and a locking portion 42 provided on the ring body 41. The ring body 41 is sleeved on the outside of the first tube body 10. The locking portion 42 is used to lock or unlock with the locking device 50. In this way, after the ring body 41 is sleeved on the outside of the first tube body 10, the locking tongue device 40 can be installed, which facilitates the installation operation of the locking tongue device 40. In other embodiments, the locking tongue device 40 may include a connecting portion connected to the outer wall of the first tube body 10 and a locking portion 42 connected to the connecting portion. For example, the connecting portion can be connected to the outer wall of the first tube body 10 by bonding or welding, which can also achieve the installation of the locking tongue device 40.

[0048] Among them, see Figure 2 The locking device 50 includes a mounting block 51, a rotating shaft 52 and a locking handle 53. The mounting block 51 is mounted on the locking sleeve 30, and the rotating shaft 52 is connected to the mounting block 51. The locking handle 53 and the rotating shaft 52 are rotatably arranged to be able to lock or unlock with the locking tongue device 40. That is, when the locking device 50 and the locking tongue device 40 are locked, the locking handle 53 is pressed on the locking portion 42. At this time, the locking sleeve 30 cannot rotate relative to the first tube body 10 and the second tube body 20, thereby achieving locking between the first tube body 10 and the second tube body 20; when the locking handle 53 is rotated to disengage from the locking portion 42, the locking sleeve 30 can rotate relative to the first tube body 10 and the second tube body 20, and the first tube body 10 and the second tube body 20 can be separated.

[0049] It can be understood that since the locking handle 53 needs to rotate relative to the locking part 42, the side of the locking part 42 facing the locking handle 53 is an arc surface, and the side of the locking handle 53 facing the locking part 42 is also an arc surface. The balance between the arc surfaces enables the rotation of the handle on the locking part 42.

[0050] In order to ensure the stability of the locking handle 53 during rotation, the locking device 50 includes two mounting blocks 51, each end of the rotating shaft 52 is installed on a mounting block 51, and the locking portion 42 and the locking handle 53 are located between the two mounting blocks 51, so that the locking handle 53 is supported by the two mounting blocks 51 to ensure the support strength.

[0051] In another embodiment, the present invention further provides a casting and rolling mill, comprising the above-mentioned pipeline structure 100 .
