Abstract
The utility model discloses a kind of negative pressure locking devices, including sleeve, described sleeve one end is equipped with connecting hole, the sleeve other end is equipped with negative pressure sucker, the connection outer end of hole is equipped with hexagonal sink hole, several negative pressure holes are evenly equipped in the hexagonal sink hole centered on the connecting hole, negative pressure hole hole deep length is greater than connecting hole hole deep length, and the negative pressure sucker is connected to each negative pressure hole；Getter device is connected by sleeve one end negative pressure sucker, so that forming negative pressure in negative pressure sucker, the nut in each negative pressure hole in the sleeve other end is sucked into fixation, prevents nut from falling off, convenient in narrow space high-speed mobile, overall structure is novel, strong applicability.
Description
Technical field
The utility model relates to dedicated locking tool correlative technology fields, it particularly relates to a kind of negative pressure locking device.
Background technique
In existing production and processing, the influence of specific processing environment is often compared in space narrow elongated
Place is not easy to fixture nut and high-speed mobile.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of negative pressure locking devices, can overcome
The above-mentioned deficiency of the prior art.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of negative pressure locking device, including sleeve, described sleeve one end are equipped with connecting hole, and the sleeve other end is equipped with negative
Sucker is pressed, the connection outer end of hole is equipped with hexagonal sink hole, is evenly equipped with centered on the connecting hole in the hexagonal sink hole
Several negative pressure holes, negative pressure hole hole deep length are greater than connecting hole hole deep length, the negative pressure sucker and each negative pressure
Hole is connected to.
Further, the number of the negative pressure hole is 6.
Further, the diameter of the negative pressure sucker is greater than the diameter of the connecting hole.
Further, the sleeve is process by chromium steel.
The utility model has the beneficial effects that getter device is connected by sleeve one end negative pressure sucker, so that in negative pressure sucker
Negative pressure is formed, the nut in each negative pressure hole in the sleeve other end is sucked into fixation, prevents nut from falling off, convenient in narrow space height
Speed is mobile, and overall structure is novel, strong applicability.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
