[0030] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0031] The embodiment of the present application discloses an airtightness detection device.

[0032] Reference Figure 1 and Figure 3 An air tightness detection device includes a fixing seat 3, a sealing component 4 for sealing the openings of the first oil pipe 11 and the second oil pipe 12, and a ventilation mechanism 5 connected to the air inlet nozzle 21 of the oil pipe joint. In this embodiment, the ventilation mechanism 5 is configured as an air pump 51, which uses the sealing component 4 to seal the openings of the first oil pipe 11 and the second oil pipe 12, and at the same time, the air pump 51 can inflate the inside of the oil pipe joint.

[0033] Reference Figure 3 and Figure 4 The fixing seat 3 is provided with a ventilation groove group 31 and a plug groove group 32 for fixing the oil pipe joint, so that the staff can accurately fix the oil pipe joint on the fixing seat 3 to ensure stability and accuracy during the detection process.

[0034] Reference Figure 1 and Figure 4 The sealing assembly 4 includes a first sealing piece 41 and a second sealing piece 42. In this embodiment, the first sealing piece 41 and the second sealing piece 42 are both made of rubber. The first sealing piece 41 is threadedly connected to the first oil pipe 11 of the oil pipe joint, and the second sealing piece 42 is plugged into the second oil pipe 12 of the oil pipe joint. Since the second sealing piece 42 is both made of rubber, the second sealing piece 42 can be plugged in along the inclined direction of the second oil pipe 12, so that the second sealing piece 42 can fit tightly with the inner wall of the second oil pipe 12, thereby sealing the first oil pipe 11 and the second oil pipe 12 of the oil pipe joint, ensuring that the oil pipe joint is in a sealed state during the detection process.

[0035] Reference Figure 2 and Figure 4 The vent groove group 31 includes an embedding groove 311 and a connecting groove 312. The embedding groove 311 of the fixing seat 3 forms an embedding fit with the embedding edge 22 of the oil pipe joint, thereby achieving preliminary fixation of the oil pipe joint. The connecting groove 312 is arranged in the embedding groove 311 and communicates with the embedding groove 311, so that the gas entering the embedding groove 311 can be transported into the first oil pipe 11 and the second oil pipe 12 through the connecting groove 312, that is, the interior of the oil pipe joint can be evenly filled with gas, and the airtightness performance of the oil pipe joint in water can be accurately reflected, which is convenient for subsequent inspection of the airtightness of the oil pipe joint.

[0036] Reference Figure 2 and Figure 4 The plug-in slot group 32 includes a first plug-in slot 321, a second plug-in slot 322 and a third plug-in slot 323. The first plug-in slot 321 is in the shape of a horizontal bar and is provided with two. The second plug-in slot 322 and the third plug-in slot 323 are both arranged in a crescent shape. Any first plug-in slot 321 forms a plug-in fit with the first plug-in portion 23 of the oil pipe joint, thereby preliminarily fixing the oil pipe joint; the second plug-in slot 322 forms a plug-in fit with the second plug-in portion 24 of the oil pipe joint, thereby further preliminarily fixing the oil pipe joint, and the third plug-in slot 323 forms a plug-in fit with the third plug-in portion 25 of the oil pipe joint, thereby greatly enhancing the stability of the oil pipe joint on the fixing seat 3.

[0037] Reference Figure 3The fixing seat 3 is also provided with a clamping mechanism 33 for clamping the oil pipe joint, ensuring that the oil pipe joint will not be displaced or loosened due to external force during the detection process, thereby further improving the accuracy of the detection.

[0038] Reference Figure 1 and Figure 3 The fixing seat 3 is symmetrically provided with clamping mechanisms 33 on both sides of the oil pipe joint. In this embodiment, any clamping mechanism 33 is configured as a quick clamp 331. Any quick clamp 331 is threadedly connected to the fixing seat 3 by a bolt. Any quick clamp 331 forms an abutment fit with the fixing portion of the fixing portion 2 of the oil pipe joint. By utilizing the configuration of the quick clamp 331, the quick clamp 331 can quickly clamp the fixing portion 2 of the oil pipe joint, and the dead point clamping principle of the quick clamp 331 is utilized to further fix the position of the oil pipe joint, which not only improves the working efficiency but also reduces the labor intensity of the staff.

[0039] Reference Figure 3 When in use, the staff puts the inflated oil pipe joint together with the fixing base 3 into the water, and judges whether the air tightness of the oil pipe joint is qualified by observing whether there are bubbles in the water. This design not only simplifies the fixing process of the oil pipe joint, but also improves the detection efficiency of the oil pipe joint.

[0040] The implementation principle of the embodiment of the present application is as follows: during actual operation, the staff first forms an embedding fit between the embedding edge 22 of the oil pipe joint and the embedding groove 311 on the fixing seat 3, and at the same time, the first plug-in portion 23, the second plug-in portion 24, and the third plug-in portion 25 of the oil pipe joint are respectively plugged into and fitted with the first plug-in groove 321, the second plug-in groove 322, and the third plug-in groove 323 on the fixing seat 3, thereby preliminarily fixing the oil pipe joint on the fixing seat 3.

[0041] Then the staff uses the two quick clamps 331 on the fixing seat 3 to make the two quick clamps 331 respectively form abutment with the fixing portion 2 of the oil pipe joint, further fixing the oil pipe joint firmly on the fixing seat 3, and then the staff uses the first sealing member 41 and the second sealing member 42 to seal the first oil pipe 11 and the second oil pipe 12 of the oil pipe joint, so that the oil pipe joint is in a sealed state.

[0042] Finally, the staff puts the inflated oil pipe joint together with the fixing seat 3 into water, and judges whether the air tightness of the oil pipe joint is qualified by observing whether there are bubbles in the water.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
