Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Fig. 1-Fig. 5 is please referred to, the present invention provides a kind of technical solution: a kind of Full-automatic gas rotz flowmeter initial-flow
Tester, including rotz flowmeter 1 and display 3, display 3 are fixed on 1 right side of rotz flowmeter, and rotz flowmeter 1 is right
End face, which is pasted, is fixed with internal screw thread cylinder 2, and protective plate 4 is arranged on the right side of display 3, and protective plate 4 blocks 3 right end of display,
4 right side of protective plate opens up threaded hole 7, and 7 internal messing screw rod 5 of threaded hole, the design of threaded hole 7 is convenient for screw rod 5 and protective plate 4
It is stably connected with, 5 right end stationary cylinder 6 of screw rod, and 5 left end of screw rod passes through protective plate 4 and is engaged in internal screw thread cylinder 2, cylinder
Body 6 facilitates the grasping of screw rod 5, after protective plate 4 is placed on 3 right side of display, 5 left end of screw rod is passed through threaded hole 7, rotates spiral shell
Bar 5 realizes that screw rod 5 is moved downward along threaded hole 7, until 5 left end of screw rod enters in internal screw thread cylinder 2, realizes protective plate 4 with this
With being indirectly connected with for internal screw thread cylinder 2, thus under the collective effect of protective plate 4 and screw rod 5,3 surrounding of display and right end quilt
Protection, avoid display 3 from being hit with this and damage, screw rod 5 is removed out of internal screw thread cylinder 2, protective plate 4 i.e. and internal screw thread
Cylinder 2 separates, and facilitates protective plate 4 and screw rod 5 etc. to reuse with this, and fixed velcro is pasted in 4 left side middle position of protective plate
Velcro hook surface block 10, the fixed sponge block in 10 left side of velcro hook surface block are pasted in hair side block 9,9 left side of velcro hair side block
11,11 left side of sponge block fits with display 3, when protective plate 4 is after the position of 3 right end of display is fixed, sponge block 11
Left side fits with display 3, so that sponge block 11 realizes the purpose for separating display 3 and protective plate 4, avoids protective plate 4
The case where there is friction between display 3 and wearing display 3 generation, after 11 deformation or damage of sponge block, by velcro
Hook surface block 10 is torn from 9 left end of velcro hair side block, can be replaced to sponge block 11.
Internal screw thread cylinder 2, screw rod 5, cylindrical body 6 and threaded hole 7 are equipped with four groups, and four groups of internal screw thread cylinders 2 are uniformly fixed on
1 right side of rotz flowmeter, four groups of threaded holes 7 are uniformly provided with 4 right side of protective plate, and four groups of screw rods 5 are engaged on four groups respectively
In threaded hole 7, four groups of cylindrical bodies 6 are separately fixed at four groups of 5 right sides of screw rod, and four groups of screw rods 5 pass through four groups of threaded holes 7 and engage
In four groups of internal screw thread cylinders 2, the protection effect of protective plate 4 is improved, enhances the bonding strength of protective plate 4 and internal screw thread cylinder 2.
Screw rod 5 and cylindrical body 6 are an integral molding structure, and integrated formed structure facilitates processing, while being improved mechanical strong
Degree.
Inclined stripe is set, and fixed thin bar 8 on rear side of 6 outer surface of cylindrical body, inclined stripe increases in 6 annular side of cylindrical body
The coefficient of friction of cylindrical body 6 facilitates the rotation of cylindrical body 6, and thin bar 8 is that cylindrical body 6 provides grasping carrier, realizes cylindrical body 6
A variety of modes of operation.
2 inside left of internal screw thread cylinder can be avoided screw rod 5 across internal screw thread by the fixed rubber pad 12 of glue, rubber pad 12
Cylinder 2 is directly contacted with 1 right side of rotz flowmeter, and screw rod 5 is avoided to wear rotz flowmeter 1.
