DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] like Figure 1-Figure 5 A snap-on drill pipe joint shown in the figure includes a drill pipe male joint 10 and a drill pipe female joint 20; a clamping block 30 and a clamping groove 40 that cooperate with each other are arranged between the drill pipe male joint 10 and the drill pipe female joint 20, and the clamping block 30 and the clamping groove 40 are both arranged on the inner side wall of the drill pipe female joint 20. The clamping block 30 is connected to an adjustment component 50 for driving it to rotate so as to realize the clamping and fixing of the clamping block 30 in the clamping groove 40.

[0026] Based on the above structure, the adjustment assembly 50 includes an adjustment rod 51, a rotating block 52 and a fastener 53; one end of the adjustment rod 51 is fixedly connected to the clamping block 30, and the other end of the adjustment rod 51 is fixedly connected to the rotating block 52; the rotating block 52 is fixedly connected to the drill pipe male joint 10 through the fastener 53.

[0027] Based on the above structure, the fastener 53 is a screw, and a screw hole matching the screw is provided on the drill pipe male joint 10. The design of the screw and the screw hole makes it very convenient to lock and disassemble the rotating block 52, saving work time and improving construction efficiency.

[0028] On the basis of the above structure, corresponding clearance grooves 60 for the rotating block 52 to pass through are respectively opened on the drill pipe male joint 10 and the drill pipe female joint 20, and the clearance grooves 60 are connected with the clamping groove 40. When disassembly work is required, the adjusting rod 51 is pushed downward by holding the rotating block 52 so that the clamping block 30 passes through the clearance groove 60 and extends into the clamping groove 40. At this time, the adjusting rod 51 is driven to rotate by the rotating block 52 so that the clamping block 30 under the adjusting rod 51 is clamped in the clamping groove 40. At this time, the rotating block 52 is locked and fixed by the screw threaded connection with the screw hole.

[0029] On the basis of the above structure, a track groove 54 for the rotation of the rotating block 52 is opened on the outer surface of the drill pipe male joint 10 , and the track groove 54 is connected with the clearance groove 60 .

[0030] Based on the above structure, a first sealing gasket 70 is provided at the joint of the rotating block 52 and the clearance groove 60. Here, the first sealing gasket 70 is preferably an O-ring, which realizes the circumferential sealing of the rotating block 52 and the clearance groove 60, and the sealing is reliable and leak-free.

[0031] Based on the above structure, the shape of the clearance groove 60 is matched with the shape of the rotating block 52 .

[0032] Based on the above structure, a second sealing gasket 80 is provided at the joint of the drill pipe male joint 10 and the drill pipe female joint 20. Here, the second sealing gasket 80 is preferably an O-ring to achieve end face sealing of the drill pipe male joint 10 and the drill pipe female joint 20, with reliable sealing and no leakage.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
