[0027] Embodiment 1:

[0028] The utility model provides a pressure test drill rod which is easy to disassemble and assemble for drilling construction. Figures 1 to 6 As shown: a pressure test drill rod for drilling construction that is easy to disassemble and assemble, comprising a rod portion 1 and a connector 3, a base 2 is fixedly installed at the bottom end of the rod portion 1, the base 2 is sleeved on the outer wall of the connector 3, and a disassembly mechanism 4 is provided between the connector 3 and the base 2;

[0029] The disassembly and assembly mechanism 4 includes a connecting rod 401, a connecting plate, a connecting block 408, and a pin rod 407. The connecting rod 401 is fixedly installed on the top of the inner wall of the base 2, and a clamping plate 402 is fixedly installed on the bottom of the connecting rod 401. A slot 403 is provided at the top of the connector 3, and a clamping groove 404 is provided at the bottom of the slot 403. The connecting rod 401 is inserted into the slot 403, and the clamping plate 402 is clamped in the clamping groove 404. The connecting plate is fixedly installed on the outer wall of the connector 3, and the connecting block 408 is fixedly installed on the outer wall of the base 2. The pin rod 407 movably penetrates the groove provided at the bottom of the connecting plate, and a pin groove 409 is provided at the bottom of the connecting block 408. The pin rod 407 is inserted into the pin groove 409, and a pull plate 406 is fixedly installed at the bottom end of the pin rod 407. A spring 410 is surrounded by the outer wall of the pin rod 407. One end of the spring 410 is fixedly installed on the top of the pull plate 406, and the other end of the spring 410 is fixedly installed on the top of the inner wall of the groove opened at the bottom end of the connecting plate 405. A movable groove 413 is opened on the connector 3, and the pull plate 406 movably passes through the connector 3 through the movable groove 413. A clamping block 414 is fixedly installed on the inner wall of the base 2, and a vertical groove 411 and an annular groove 412 are opened on the outer wall of the connector 3, and the clamping block 414 is clamped in the annular groove 412.

[0030] Specifically, the above technical solution is as follows: the pull plate 406 is pulled downward, the pull plate 406 drives the pin 407 to move downward, the pull plate 406 stretches the spring 410, and the pull plate 406 drives the pin 407 to disengage from the pin groove 409, so that the pin 407 no longer limits the connecting block 408. At this time, the rod 1 is rotated, the rod 1 drives the base 2 to rotate, the base 2 drives the card plate 402 to rotate through the connecting rod 401, and the base 2 also drives the card block 414 to slide in the annular groove 412, so that the card plate 402 and the card block 414 rotate. The rod 1 is then pulled upwards to allow the rod 1 to drive the base 2 to detach from the connector 3, thereby completing the disassembly of the rod 1. This mechanism makes it easier for personnel to disassemble and assemble the pressure test drill rod, thereby improving the disassembly and assembling efficiency of the personnel and solving the problem that most existing pressure test drill rods use the base 2 thread for threaded connection, which causes the thread to be easily worn after long-term use and is easily stuck during disassembly and assembling, thereby affecting the disassembly and assembling efficiency.

[0031] Furthermore, the vertical groove 411 is vertically connected to the annular groove 412, and the vertical groove 411 passes through the top of the connector 3, and the clamping block 414 is adapted to the vertical groove 411 and the annular groove 412;

[0032] Among them, by providing the clamping block 414, the connection strength between the connecting head 3 and the base 2 can be improved, thereby ensuring the normal use strength of the rod 1.

[0033] Furthermore, the number of the connecting block 408, the connecting plate 405, and the pin rod 407 are all two, and the pin rod 407 is adapted to the pin groove 409;

[0034] Among them, by providing the pin rod 407, the pin rod 407 can be inserted into the pin groove 409, so as to limit the connection block 408 and prevent the base 2 and the connector 3 from rotating relative to each other.

[0035] Embodiment 2:

[0037] Specifically, in the above technical solution, after the connection between the rod part 1 and the connecting head 3 is completed, the stop block 5 can be inserted into the movable groove 413, so that the slider 7 slides into the slide groove 9, and the stop block 5 limits the pull plate 406, thereby improving the stability of the pull plate 406 in the movable groove 413 when the pressure test drill rod is in use, thereby ensuring the installation stability of the pressure test drill rod and ensuring the normal use of the pressure test drill rod. The structure is simple and the practicability is strong.

[0038] Furthermore, a slot pad 8 is fixedly installed on the inner wall of the slide slot 9, and the slot pad 8 is in close contact with the outer wall surface of the slide block 7;

[0039] Among them, by providing the groove pad 8, the connection tightness between the sliding block 7 and the sliding groove 9 can be increased, thereby improving the stability of the stop block 5 in the moving groove 413.

[0040] Furthermore, the material of the slot pad 8 is wear-resistant rubber;

[0041] Among them, by using wear-resistant rubber as the material of the slot gasket 8, the service life of the slot gasket 8 can be increased.

[0042] Furthermore, pull rings 6 are fixedly installed on both sides of the stop block 5;

[0043] Wherein, by providing the pull ring 6, it is convenient for personnel to pull the stop block 5 through the pull ring 6, thereby facilitating the operation of personnel.
