The present invention solves the technical problem of：A pressure probe locating piece is provided, can solve the problem that makes in pressure probe
The orientation problem of the circumferential position of used time.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of pressure probe locating piece, it is characterised in that：Comprising positioning block main body (1), through hole (2), screwed hole (3), recessed
Groove (4) and air-bubble level (5)；Positioning block main body (1) is structure as a whole, including quadrangle base and cylindrical boss；Through hole
(2) cylindrical boss center is opened in, screwed hole (3) is opened in cylindrical boss both sides, and it is any that groove (4) is opened in quadrangle base
Side；Air-bubble level (5) is set in groove (4) and fixed.
Further, the quadrangle base of positioning block main body (1) can be as needed square or rectangle；Through hole
(2) cylindrical boss center is opened in, it is coaxial with cylindrical boss, it is vertical with quadrangle base.
Further, screwed hole (3) is opened in cylindrical boss both sides, and two screwed holes (3) axis is overlapped, with cylindrical boss axle
Line is intersecting and vertical；Groove (4) is opened in quadrangle base either side, parallel with base.
Further, positioning block main body (1) via through holes (2) are placed on pressure probe bar afterbody, according to pressure probe bar size, lead to
Hole (2) a diameter of 4+0.1~10+0.1mm。
Further, the quadrangle base thickness of positioning block main body (1) is more than or equal to 3mm；Groove (4) width is less than quadrangle
Base thickness；Air-bubble level (5) size is according to groove (4) selection of dimension.
Further, air-bubble level (5) built-in in locating piece may not include, and change the external air-bubble level (5) of cooperation into
The pressure probe positioning block structure used is also comprising in this invention.
The beneficial effects of the invention are as follows：
In the present invention, directly air-bubble level (5) is placed in inside locating piece or coordinates external bubble level by application
The pressure probe locating piece that instrument (5) is used, conveniently can be adjusted to level by pressure probe, make probe aerodynamic center just to coming
Stream, can effectively reduce during pressure probe use the position error because of caused by positioning, it is ensured that the accuracy of measurement data.
Meanwhile, the present invention is simple in construction, and effect significantly, is suitably promoted the use of.
