Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings 1 to 5 in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model provides a quick constant-pressure plug which comprises a plug body 19 for connecting a helium leak detector with a power steering tube, wherein the plug body 19 comprises an air inlet tube 2, the end part of the air inlet tube 2 is connected with a switching tube 14, an air inlet channel 3 is arranged in the air inlet tube 2, a switching channel 4 is arranged in the switching tube 14, a communicating cavity 12 is arranged in a spherical joint 6 of the power steering tube, the air inlet channel 3 is connected with the communicating cavity 12 through the switching channel 4, two ends of the spherical joint 6 are opened, the switching tube 14 penetrates through the spherical joint 6, two sides of the air inlet tube 2 are provided with annular mounting grooves 15, a sealing ring 11 is mounted in the mounting groove 15, the sealing ring 11 is connected with the spherical joint 6 in a sealing manner, the sealing ring 11 can further enable the communicating cavity 12 to be in a sealing state, and the communicating cavity 12 is communicated with the power steering tube, the fixing seat 1 is sleeved at one end, close to the adapter tube 14, of the air inlet tube 2, the diameter of the fixing seat 1 is larger than that of the opening of the spherical joint 6, and a positioning blocking effect is achieved.

The one end that intake pipe 3 was kept away from to adapter tube 14 is connected with fixed head 13, fixed head 13 includes upper fixed plate 10 and the bottom plate 8 that is connected with adapter tube 14, upper fixed plate 10 and bottom plate 8 parallel arrangement, leave the space between upper fixed plate 10 and the bottom plate 8, installation round pin axle 7 between upper fixed plate 10 and the bottom plate 8, rotate installation gear lever 9 on the round pin axle 7, through the rotation of baffle 9, realize the fixed of end cap body 19 fixed head 13 end.
