Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-4, the present invention includes a support body 10, a connection handle 16, a handle sleeve 28, a sealing joint 24, a first positioning block 46, and a second positioning block 48, wherein the support body 10 is substantially O-shaped, the center has a step hole 12, and the two ends have a first step hole 15 and a second step hole 23 opposite to the center hole. The connection handle 16 is generally cylindrical and has an internal passage 20, one end of which passes through the central stepped bore 12 of the support body and the other end of which is provided with a connection handle projection 33, the connection handle projection 33 abutting against a shoulder formed by the central stepped bore 12. Handle sleeve 28 is looped over connecting handle 16 with end 25 abutting against support body end face 29, and handle sleeve 28 and connecting handle 16 are secured together by set screw 58 so that connecting handle 16 cannot move or rotate relative to the support body. Without departing from the concept of the present invention, the connection handle 16 may be fastened in other forms, such as a groove is formed on the outer surface of the connection handle 16 adjacent to the support body end surface 29, and a snap ring is disposed in the groove.

The sealing nipple 24 has an internal passage 22 with a tapered surface 41 at one end for insertion into the central flow passage of the attached flange 56 and a threaded end for mating with the end of the attachment handle protrusion 33. To provide a good seal, an annular groove 37 is provided on the cylindrical outer surface of the adjacent conical surface 41, in which the O-ring 18 is disposed, while an annular groove 31 is provided on the end surface of the connecting handle projection 33, in which the O-ring 26 is disposed. The sealing joint 24 is connected to the end of the connecting handle 16 in a threaded manner for easy removal and replacement to accommodate flanges of different internal diameters.

The utility model discloses an aspect lie in and realize quick connection by flange 56, through first step hole 15 at support main part 10 both ends, set up first hook 34 in the second step hole 23, second hook 36, specifically, first hook 34, second hook 36 are cylindricly, the top is provided with first opening 43, second opening 45, first opening 43 is opposite with second opening 45's orientation, there is first arch 35 bottom respectively, the arch 39 of second, the step hole at support main part 16 both ends is passed to the one end of hook, first arch 35, the arch 39 of second supports respectively and leans on first step hole 15, the shaft shoulder that second step hole 23 formed. In order to prevent the hook from rotating relative to the support body, a horizontal limiting straight edge 50 is arranged at the lower end of the stepped hole 15, a horizontal limiting straight edge 40 is arranged at the upper end of the stepped hole 23, a flat position 52 is arranged at the lower end of the first protrusion 35, and a flat position 54 is arranged at the upper end of the second protrusion 39. When the first hook 34 and the second hook 36 are inserted into the first stepped hole 15 and the second stepped hole 23, the hooks cannot rotate due to the interaction of the flat part and the limiting straight edge, and the opening of the hook faces to a circumference which is centered on the sealing joint 24 and has the diameter of the straight distance between the first hook 34 and the second hook 36. The cylindrical outer surfaces of the first and second hooks 34 and 36 are provided with annular grooves in which a first and second snap rings 53 and 55 are respectively provided, and the first and second hooks 34 and 36 are thereby fastened to both ends of the support body 10. Referring to fig. 5, in use, the handle sleeve 28 is held by one hand, the first hook 34 and the second hook 36 are respectively inserted into the bolt holes of the connected flange, the sealing joint 24 is inserted into the central flow passage hole of the connected flange 56, and the whole joint is rotated to the right until the first hook 34 and the second hook 36 hook the connected flange. Preferably, the first opening 43 and the second opening 45 are circular arc-shaped. The circular arc shaped opening on the one hand fits more closely against the bolt hole wall of the flange 56 and on the other hand gives the hook sufficient rigidity so as not to bend.

In a preferred embodiment of the present invention, the positioning device comprises a set of first positioning blocks 46 and second positioning blocks 48 adjacently disposed beside the first hooks 34 and the second hooks 36, wherein the positioning blocks are substantially rectangular and fastened to one side of the support body 16 by locking screws 51. When the connecting flange is horizontally connected with the connected flange, the contact area between the first positioning block 46 and the flange to be connected can be effectively increased through the second positioning block 48, so that the whole connector is supported, and the phenomenon that the whole connector is inclined due to self weight is avoided.

In another preferred embodiment of the present invention, a safety locking device is disposed on the supporting body 10, which comprises a seat 11, a latch 13, a pull rod 17, a spring 19 and a stop ring 21. The seat 11 is fixed on the top of the support body 10 by screws 47, with its axis parallel to the axis of the connecting handle 16, and has a large hole 30 towards one end of the connected flange 56 and a small hole 32 at the other end. The plug 13 is cylindrical and has a central hole. One end of the pull rod 17 is provided with a pull rod protrusion 38, the pull rod 17 is inserted into the bolt 13 from one end and is stopped at a boss 49 formed on the inner surface of the bolt, and the spring 19 is inserted into the bolt 13 from the other end and is sleeved on the pull rod 17 and is stopped at the boss 49. The plug assembly is inserted into the housing 11 through the large hole 30 and the end of the pull rod 17 extends through the small hole 32 and is connected to the retainer 21. The latch 13 is shorter in length than the housing 11 and the latch 13 is exposed from the housing 11 in an initial state due to the tension of the spring 19. When the retainer ring 21 is pulled, the retainer ring 21 drives the pull rod 17, thereby forcing the bolt 13 to move axially together in the large seat hole 30. Referring specifically to fig. 5, the latch 13 is inserted into the bolt hole at the top of the flange, so that the first and second hooks 34 and 36 cannot rotate relative to the flange 56, and the locking function is achieved. When the connection with the flange 56 is to be disconnected, the retaining ring 21 is pulled, the bolt 13 is pulled to retract into the seat 11, the handle sleeve 28 is held, and the rotary joint is connected with the first hook 34 and the second hook 36 to be disconnected from the engagement with the flange 56. In order to simplify the operation, an L-shaped fork 42 can be arranged between the pull rod 17 and the baffle ring 21, one end of the fork 42 is a Y-shaped opening and is buckled on the pull rod 17, and the L-shaped corner is fixed on the seat 11 through a screw 57. When in use, the bolt 13 can be extended and retracted relative to the seat 11 only by pressing the shifting fork 42 downwards.

The invention has been described with reference to the preferred embodiments, to the above examples which are not intended to limit the invention, and from reading the present description, those skilled in the art will be able to conceive of numerous modifications and variations to this structure, without departing from the inventive concept, any obvious alternative falling within the scope of the invention.
