The utility model discloses simple structure buckles owing to the card foot that has adopted little square hole and extension corresponds mutually, and its dust cover device has good positioning to make dust cover device be convenient for assemble, not only the shield can not drop, makes hand wheel and shield typeface direction keep unanimous moreover, thereby has improved the appearance quality of product.
Description
Technical field
This utility model relates to a kind of dust-proof cover device, belongs to cylinder valve technical field.
Background technology
Cylinder valve is because of its special applied environment; its dust cap not only has dust-proof; also act as simultaneously and prevent exterior part arbitrarily dismounting effect; when original dust-proof cover device assembles; often misalignment is the most just filling, and makes the font on handwheel and the font direction on dust cap inconsistent, have impact on the presentation quality of product; and often also have dress loosely just to have obscission in transportation, it is therefore desirable to improved.
Utility model content
This utility model is for drawbacks described above, it is therefore intended that provides a kind of simple in construction, improves dust-proof cover device installation capability.
For this technical solution adopted in the utility model it is: this utility model includes handwheel (1), described handwheel (1) is provided with the dust cap (2) being correspondingly arranged with described handwheel (1)；
Being provided with the installing hole installing described dust cap (2) on described handwheel (1), described dust cap (2) is in valve rod (3) top, described dust cap (2) and valve body (4) and forms the encirclement to described valve rod (3)；
Described handwheel (1) installing hole is circumferentially provided with some draw-in grooves (11), described dust cap (2) is provided with card and sets into the card base (21) in described draw-in groove (11).
It is provided with on described handwheel (1) installing hole and extends the square draw-in groove (12) that the cross section arranged is square, described dust cap (2) is provided with card and sets the square card base (22) into described square draw-in groove (12).
It is provided with three draw-in grooves (11) in described handwheel (1), corresponding dust cap (2) is provided with three card bases (21).
Coordinated by the form of boss between described draw-in groove (11) and card base (12).
Coordinated by the form of boss between described square draw-in groove (12) and square card base (22).
The utility model has the advantages that: this utility model simple in construction, owing to have employed, small square hole is corresponding with the card base of prolongation to interlock, its dust-proof cover device is had good positioning, so that dust-proof cover device is easy to assembling, not only dust cap does not comes off, and make handwheel keep consistent with dust cap font direction, thus improve the presentation quality of product；2) this utility model further have employed the version of boss and achieves the connection between draw-in groove and card base and square draw-in groove and square card base, while realizing location, further improves the sealing property between handwheel and dust cap.
