In order to further enhance the structural stability, a locking nut (not shown in the figure) can be threadedly connected with the tensioning screw 21, the locking nut abuts against the bottom wall of the pressure cover 3, so as to prevent the pressure cover 3 from moving when the inner blowout prevention tool leaks.

[0040] The implementation principle of the embodiment 1 of the application is as follows: in use, the quick-mount pressure testing head 5 matched with the inner blowout prevention tool to be tested is inserted into the pressure testing port 4 until the boss 52 of the quick-mount pressure testing head 5 abuts against the upper surface of the pressure testing port 4, the quick-mount pressure testing head 5 and the pressure testing port 4 are sealed and connected through the first sealing ring 7 and the third sealing ring 18, then the inner blowout prevention tool to be tested is inserted through the gap 6 and is inserted into the corresponding quick-mount pressure testing head 5 until the end surface of the inner blowout prevention tool abuts against the boss 52 of the quick-mount pressure testing head 5, and the sealing connection is realized through the second sealing ring 8 and the sealing ring in the inner blowout prevention tool; then the connecting column 10 of the quick-mount pressure plate is aligned with the corresponding gap 6, then the quick-mount pressure plate is horizontally moved towards the gap 6, the connecting column 10 of the quick-mount pressure plate is moved into the gap 6, the lower limiting plate 11 abuts against one side of the pressure cover 3 close to the pressure testing table 2, the upper limiting plate 9 abuts against one side of the pressure cover 3 away from the pressure testing table 2, then the lower limiting plate 11 abuts against one end of the inner blowout prevention tool away from the quick-mount pressure testing head 5, thereby fixing and plugging the inner blowout prevention tool.

[0042] Embodiment 2:

[0043] With reference to Figure 4 and Figure 2 , the difference between the embodiment and embodiment 1 is that the quick-mounting pressing plate comprises a clamping plate 12 and an abutting block 13. The clamping plate 12 is provided with an opening 14 for the internal blowout prevention tool to pass through on the side close to the gap 6, so that the clamping plate 12 is U-shaped. The cross section of the opening 14 is larger than the cross section of the internal blowout prevention tool and smaller than the cross section of the gap 6. The thickness of the clamping plate 12 is greater than the thickness of the pressing cover 3. The outer edge of the clamping plate 12 is provided with a plug-in groove 15 for plug-in cooperation with the pressing cover 3. The thickness of the plug-in groove 15 is equal to the thickness of the pressing cover 3. The upper wall of the plug-in groove 15 is used for abutting against the upper surface of the pressing cover 3, and the lower wall of the plug-in groove 15 is used for abutting against the lower surface of the pressing cover 3. When the plug-in groove 15 of the clamping plate 12 is plugged in the gap 6 of the pressing cover 3, the clamping plate 12 can be clamped on the pressing cover 3 to limit the up-and-down movement.

[0044] With reference to Figure 3 , Figure 4 and Figure 3 , the abutting block 13 is slidingly arranged on the clamping plate 12. The abutting block 13 is aligned with the corresponding opening 14. The sliding direction of the abutting block 13 is perpendicular to the plane where the opening 14 is located. The abutting block 13 is used for covering and pressing the end of the internal blowout prevention tool away from the quick-mounting pressure test head 5. The cross section of the abutting block 13 is larger than the cross section of the internal blowout prevention tool, and the cross section of the abutting block 13 is smaller than the cross section of the opening 14. The clamping plate 12 is provided with an adjusting member for adjusting the sliding of the abutting block 13.

[0045] With reference to Figure 4 and Figure 3 , in order to facilitate the abutting block 13 to slide towards the direction close to or away from the clamping plate 12, the adjusting member comprises two screw rods 16 arranged oppositely. The two screw rods 16 are rotationally arranged on the opposite sides of the clamping plate 12. The rotation axis of the screw rod 16 is parallel to the sliding direction of the abutting block 13. The opposite sides of the abutting block 13 are fixedly provided with a connecting block 17 corresponding to the screw rod 16. The connecting block 17 is threadedly sleeved on the corresponding screw rod 16.

[0046] With reference to Figure 4 and Figure 4The thickness of the abutting block 13 is greater than that of the clamping plate 12, the connecting block 17 is located on the side of the abutting block 13 away from the clamping plate 12, and the abutting block 13 can pass through the opening 14 to be suitable for different types and sizes of internal blowout preventer tools.

[0047] Referring to Figure 5 and ​ The clamping plate 12 is slidably connected with a sliding block 25 on the side close to the lead screw 16, the sliding block 25 corresponds to the lead screw 16 one-to-one, the sliding direction of the sliding block 25 is perpendicular to the rotation axis of the lead screw 16, the first gear 24 is fixedly sleeved on the end of the lead screw 16 close to the clamping plate 12, the second gear 26 is fixed on the sliding block 25, the first gear 24 is engaged with the corresponding second gear 26, the clamping plate 12 is provided with a spring 27 for pushing the sliding block 25 to slide towards the direction close to the corresponding lead screw 16, and the end of the spring 27 away from the clamping plate 12 is fixed on the corresponding sliding block 25. The sliding block 25 is pushed by the spring 27 to keep the second gear 26 in engagement with the corresponding first gear 24, thereby limiting the rotation of the lead screw 16, so that the abutting block 13 is not easy to move after being pressed, and damage caused by accidental release of pressure at the other end of the internal blowout preventer tool is avoided as much as possible.

[0048] The implementation principle of the embodiment 2 of the present application is as follows: after the internal blowout preventer tool is installed on the quick-mounting pressure testing head 5, the sliding block 25 is slid towards the direction away from the corresponding lead screw 16, so that the second gear 26 is disengaged from the corresponding first gear 24, then the lead screw 16 is rotated, the lead screw 16 drives the connecting block 17 to slide the abutting block 13 towards the direction close to or away from the clamping plate 12, according to the actual length of the internal blowout preventer tool, the abutting block 13 is moved to the required position, then the sliding block 25 is loosened, the sliding block 25 is close to the corresponding lead screw 16 under the elastic action of the spring 27, so that the first gear 24 is engaged with the second gear 26 to limit the rotation of the lead screw 16.

[0049] Then the opening 14 of the clamping plate 12 is aligned with the gap 6, the lead screw 16 is located below or above the clamping plate 12, then the clamping plate 12 is horizontally moved towards the gap 6, so that the plug-in slot 15 on the clamping plate 12 is gradually clamped and matched with the gland 3, until the abutting block 13 abuts against the end of the corresponding internal blowout preventer tool away from the quick-mounting pressure testing head 5 to cover and press the internal blowout preventer tool; since the clamping plate 12 cannot move up and down, the connecting block 17 cannot rotate on the lead screw 16, the lead screw 16 cannot rotate under the engagement of the first gear 24 and the second gear 26, and thus the abutting block 13 cannot move up and down, so as to ensure the abutting effect on the internal blowout preventer tool, and realize that the pressure test can be simultaneously performed on internal blowout preventer tools of different lengths and sizes, thereby greatly expanding the application range.

[0050] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
