Description
Technical Field
The utility model relates to a piezoelectric valve nozzle convenient to dismouting.
Background
With the acceptance of the electronic industry, the automobile industry, the energy and biological medicine industry and the like, the piezoelectric injection valve replaces the original production equipment in part of domestic and foreign enterprises, so that the original production efficiency and quality are improved. The piezoelectric structure has the advantages of small volume, extremely high displacement resolution, high response speed, low-voltage driving, large output force and the like, and the market leading position of the piezoelectric injection valve is also determined. However, facing a wider market, new challenges are also faced. The technical requirements of the nozzle are improved due to the diversification of the types of the ejected fluids, but the nozzle assembling and disassembling process is complex, various parts are often disassembled to disassemble the nozzle from the parts, the nozzle can be fixed only by assembling the various parts, the parts are excessive, the nozzle is unstable to assemble, and the nozzle is not easy to fix due to looseness after long-term use.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.
A piezoelectric valve nozzle convenient to disassemble and assemble comprises a clamping jaw and a nozzle fixing seat, wherein a through hole is formed in the clamping jaw, and a plurality of bosses are arranged on the end face of the tail end of one end of the clamping jaw;
the nozzle fixing seat is provided with a seat stand, a plurality of positioning holes are formed in the end face of the seat stand and are in fastening fit with bosses, external threads are formed in the side wall of the seat stand, one end of the nozzle fixing seat is inserted into the through hole in the clamping jaw, the clamping jaw is fixed on the nozzle fixing seat in a fastening fit mode through the bosses and the positioning holes, an adjusting nut in threaded fit with the external threads is arranged on the seat stand at the other end of the nozzle fixing seat, a nozzle is placed in the adjusting nut, and the nozzle is fixed in the adjusting nut through mutual screwing of.
As a further aspect of the present invention: and a claw groove is formed in the surface of one end of the claw.
As a further aspect of the present invention: and a threaded groove is formed in the surface of the adjusting nut.
As a further aspect of the present invention: the number of the bosses is three.
As a further aspect of the present invention: the number of the positioning holes is three.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the structure adopts novel reasonable design simple structure, and the effectual nozzle that has improved dismantles efficiency, through spanner increase moment of torsion, makes the nozzle fixed tighter, is difficult to the shake pine, improves the stability of using.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
