DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described below by specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0024] REFERENCE Figures 1-5 A self-locking type drill tool adapter joint thread structure, comprising drill rod one 1, drill rod two and fixed mechanism 3.

[0025] One end of drill rod 1 is provided with drill rod 2, and one end of drill rod 1 is provided with a groove 4. A fixing mechanism 3 is provided in the groove 4, and the fixing mechanism 3 is connected to drill rod 2.

[0026] The fixing mechanism 3 includes a rotating shaft 31, a rope 32, a slider 33, a locking block 34, a spring 35, and a baffle 36. The rotating shaft 31 is rotatably connected to the drill rod 1. One end of the rotating shaft 31 extends into the locking groove 4 and is fixedly wound with the rope 32. One end of the rope 32 is fixedly connected to the slider 33. The slider 33 slides in the locking groove 4. The locking groove 4 is engaged with the locking block 34. One end of the locking block 34 is fixedly connected to the drill rod 2. Through the cooperative design between the drill rod 1, the drill rod 2, the locking groove 4, the slider 33, the locking block 34, the threaded groove 5, the threaded groove 2, and the rotating shaft 31, the operator only needs to insert the drill rod 1 and the drill rod 2 and rotate them at a certain angle (less than 90°) to achieve the effect of quick assembly and disassembly between the drill rod 1 and the drill rod 2, which greatly improves convenience and efficiency.

[0027] In this embodiment, the slot 4 has a second threaded groove 6, and the block 34 has a first threaded groove 5. The first threaded groove 5 and the second threaded groove 6 are threadedly connected. The slider 33 is in contact with the block 34. Both the slider 33 and the block 34 are adapted to the slot 4. The first threaded groove 5 and the second threaded groove 6 are adapted to each other. Through the interaction between the first threaded groove 5 and the second threaded groove 6, not only can the block 34 be engaged with the drill rod 1, but also the transmission of the block 34 can make the drill rod 1 and the drill rod 2 move closer to each other, and make the sealing gasket 8 and the sealing gasket 9 fit tightly together. The block 34 and the slider 33 are adapted to each other.

[0028] In this embodiment, a spring 35 is fixedly connected to the slider 33. One end of the spring 35 is fixedly connected to the drill rod 1. The slider 33 returns to its original state through the force of the spring 35.

[0029] In this embodiment, a baffle 36 is fixedly connected to one end of the rotating shaft 31. The baffle 36 prevents the rope 32 from coming off the rotating shaft 31 during the process of the rotating shaft 31 winding the rope 32.

[0030] In this embodiment, a groove 7 is provided on the drill rod 1, and the rotating shaft 31 rotates in the groove. The groove 7 can reduce the wear of the rotating shaft 31. One end of the rotating shaft 31 is provided with an internal hexagonal groove, which facilitates the operation of the rotating shaft 31 by the operator using tools. Both the drill rod 1 and the slider 33 are provided with limit grooves, which correspond to each other and are used to limit the slider 33. After the drill rod 1 and the drill rod 2 are assembled, they can be connected to the slider 33 and the two limit grooves on the drill rod 1 by fixing screws (not shown in the figure).

[0031] In this embodiment, a sealing gasket 8 is fixedly installed at one end of drill rod 1, and a sealing gasket 9 is fixedly installed at one end of drill rod 2. The sealing gasket 8 and the sealing gasket 9 are in contact and connected to improve the sealing performance.

[0032] Working principle: When in use, first, align the locking block 34 on drill rod 2 with the slider 33 in the slot 4. Then, insert the locking block 34 into the slot 4, and align the thread groove 5 with the thread groove 6. During this process, the locking block 34 and the slider 33 interact, causing the slider 33 to slide upward a certain distance in the slot 4, and causing the slider 33 to disengage from the obstruction of the thread groove 6, and causing the spring 35 to be compressed.

[0033] Then, the drill rod 2 is rotated at a certain angle, so that the thread groove 5 and the thread groove 6 are connected. During this process, through the interaction between the thread groove 5 and the thread groove 6, and the transmission of the locking block 34, the drill rod 1 and the drill rod 2 are brought closer together, and the sealing gasket 8 and the sealing gasket 9 are tightly fitted. When the thread groove 5 and the thread groove 6 are fully engaged, the locking block 34 is disengaged from the slider 33. At this time, through the elastic potential energy of the spring 35, the slider 33 returns to its original shape and blocks and limits the locking block 34, thereby achieving the effect of rapid assembly between the drill rod 1 and the drill rod 2.

[0034] When disassembling drill rod 1 and drill rod 2, foreign objects are removed from the internal hexagonal groove on the rotating shaft 31, and a hexagonal screwdriver is connected to the internal hexagonal groove on the rotating shaft 31. Then, the rotating shaft 31 is rotated at a certain angle. During this process, the rotating shaft 31 winds up the rope 32, and the rope 32 pulls the slider 33 upward, causing the slider 33 to release its obstruction of the locking block 34. Then, the drill rod 2 is rotated in the opposite direction, causing the threaded groove 5 on the locking block 34 to disengage from the threaded groove 6. Finally, the locking block 34 is pulled out of the locking groove 4, thereby achieving the effect of quick disassembly between drill rod 1 and drill rod 2.

[0035] The technological advancement of this invention compared to the prior art is that, through the cooperation of various components, drill rod 1 and drill rod 2 can be quickly assembled and disassembled by simply inserting them together and rotating them at a certain angle (less than 90°), which greatly improves convenience and efficiency. Moreover, the structure is simple and more practical.
