Two auricles are respectively equipped with outside the diametric(al) at upper barrel cover and lower barrel cover bottom surface place, locking clamp depressed area in matrix is placed in the auricle position of two barrel covers, by lock-screw, two auricles are compressed, after compressing, the surface of contact of two auricles coordinates formation flat seal face, the cylinder annular space that inner formation is through;
Upper barrel cover cylinder top is provided with to bleed and connects hole, and bleeding to connect on hole is provided with air extraction connector, and switching flexible pipe is connected on air extraction connector, and lower barrel cover cylinder bottom is provided with at least 3 air intake openings.
Described air intake opening is fan-shaped distribution, and angular range is 120 degree, make to bleed connect hole and each fan-shaped gas inlet mouth axis at grade.
The surface of contact of two described auricles is provided with hermetically-sealed construction, for realizing the thorough sealing of two auricles.
The hollow space of upper barrel cover and the hollow space of lower barrel cover measure-alike.
The two side ends mask of upper barrel cover, lower barrel cover has the semicircle orifice with work pieces mate spot size same diameter, can rotate after two barrel cover combinations around workpiece.
The utility model advantage is compared with prior art:
(1) the utility model adopts the mode of switching flexible pipe and suction interface combination, and solve the drawback that small space cannot use, applicability is stronger;
(2) the utility model adopts flexible pipe connecting tooling main body and suction gun, and sealing property is more reliable;
(3) the utility model uses the principle that fan-shaped flowing gas is dynamically swept along, and sweep along effect stronger, measured deviation is little.

Embodiment
Referring to accompanying drawing, the utility model is described in detail.
As shown in figures 1 to 6, one is used for the position suction gun single-point leak detection tool equipment that is spirally connected, comprise barrel cover 1, lower barrel cover 6, locking clamp 4, lock-screw 3, bleeding connects hole 5 and switching flexible pipe 8, upper barrel cover 1 and lower barrel cover 6 main body are the semi-circular cylindrical structure of hollow, and the alignment of upper barrel cover 1, lower barrel cover 6 end face is connected and the position that is spirally connected on workpiece 12 is included portion;
Two auricles are respectively equipped with outside the diametric(al) at upper barrel cover 1 and lower barrel cover 6 bottom surface place, locking clamp 4 depressed area in matrix is placed in the auricle position of two barrel covers, by lock-screw 3, two auricles are compressed, after compressing, the surface of contact of two auricles coordinates formation flat seal face, the cylinder annular space that inner formation is through; Upper barrel cover 1 cylinder top is provided with to bleed and connects hole 5, bleeds to connect on hole 5 to be provided with air extraction connector, and switching flexible pipe 8 is connected on air extraction connector, and lower barrel cover 6 cylinder bottom is provided with at least 3 air intake openings 7.
Described air intake opening 7 is in fan-shaped distribution, and angular range is 120 degree, make to bleed connect hole 5 and each fan-shaped gas inlet mouth 7 axis at grade.The surface of contact of two auricles is provided with hermetically-sealed construction and can adopts plane sealing pad or seal coating, for realizing the thorough sealing of two auricles.
The hollow space of upper barrel cover 1 and the hollow space of lower barrel cover 6 measure-alike.The two side ends mask of upper barrel cover 1, lower barrel cover 6 has the semicircle orifice with the measure-alike diameter of workpiece 12 matching part, can rotate after two barrel cover combinations around workpiece 12.
Embodiment
Upper barrel cover 1 and lower barrel cover 6 main body are the semi-circular cylindrical structure of hollow, exradius 16mm, length 22mm.The hollow space of upper barrel cover 1 and the hollow space of lower barrel cover 6 measure-alike, be radius 11mm, the half cylindrical space of length 16mm.The opening radius size at upper barrel cover 1, lower barrel cover 6 both ends is identical with the matching part of workpiece 12, and thickness is not less than 1mm.Upper barrel cover 1, lower barrel cover 6 and the near sites form fit that is spirally connected of workpiece 12 position that will be spirally connected is included portion, forms the annular space of connection.Upper barrel cover 1 and lower barrel cover 6 are coordinated by middle parting plane, the long 22mm in mating surface auricle side, and the outer lateral extent 42mm of two ears, the planar section width of auricle outside is about 4.75mm.Upper barrel cover 1 top has one and bleeds and connect hole 5 (diameter 6mm), and lower barrel cover 6 has 5 (more than 3) air admission holes 7 (diameter 1mm), and in fan-shaped distribution, and angle is apart from being 60 degree.Two barrel cover end face alignment during installation, bleeding, it is identical apart from same end face distance with fan-shaped gas inlet mouth 7 position to connect hole 5.Lock-screw 3 is compressed by the locking auricle position of clamp 4 to two barrel covers, realizes the press seal of barrel cover plane and anchor ring after two side compressions.Air extraction connector inserts to bleed and connects hole 5, and is fixed as one (also can be processed as a part) by modes such as splicing; Switching flexible pipe 7 one end and suction interface 5 grafting are combined.
