Description
Technical Field
The utility model relates to a deep hole rubber coating technical field specifically is a syringe needle nozzle for injection valve.
Background
The normal injection valve nozzle for the existing injection valve is flat, can only reach 1-2 mm from the highest surface of a product, and cannot extend into a deep hole for gluing. To this end, we propose a needle nozzle for an injection valve.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a syringe needle nozzle for injection valve to solve the problem that provides among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a syringe needle nozzle for injection valve, includes fixed nozzle, and fixed nozzle's bottom activity sets up extra long nozzle, and the inner wall of fixed nozzle lower extreme sets up the internal thread, and fixed nozzle lower extreme inner wall sets up sealed rubber ring, and sealed rubber ring sets up at the internal thread top, and the outer wall setting that extra long nozzle is close to the top sets up the external screw thread that matches with the internal thread, and the top of extra long nozzle sets up annular gasket.
Furthermore, a fastening nut is fixedly arranged at the top of the fixed nozzle, and the fixed nozzle and the fastening nut are provided with a through hole with the aperture larger than the outer diameter of the annular gasket.
Furthermore, a through hole is formed in the middle of the sealing rubber ring, and the diameter of the through hole is larger than the outer diameter of the external thread and smaller than the outer diameter of the annular gasket.
Furthermore, the bottom of the fixed nozzle is a flat-bottom nozzle, and the bottom of the lengthened nozzle is a conical nozzle.
Furthermore, a gap of 0.5mm is reserved between the external thread and the annular gasket.
Compared with the prior art, the beneficial effects of the utility model are that: add extension nozzle on original fixed nozzle, the dismouting is changed on fixed nozzle that extension nozzle can be convenient through threaded connection mode, and can guarantee its leakproofness through sealing rubber ring and annular gasket, and the extension nozzle can be extended to 20 millimeters to infiltration point that can be convenient is glued.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a syringe needle nozzle for injection valve, includes fixed nozzle 1, the bottom activity of fixed nozzle 1 sets up extension nozzle 2, and the inner wall of fixed nozzle 1 lower extreme sets up internal thread 4, and 1 lower extreme inner wall of fixed nozzle sets up sealed rubber ring 3, and the top of screw thread 4 including sealed rubber ring 3 sets up, and extension nozzle 2 is close to the outer wall setting at top and internal thread 4 assorted external screw thread 5, and the top of extension nozzle 2 sets up annular gasket 6.
The top of the fixed nozzle 1 is fixedly provided with a fastening nut, the fixed nozzle 1 and the fastening nut are provided with through holes with the aperture larger than the outer diameter of the annular gasket 6, the fixed nozzle 1 can be directly connected with a valve seat of the injection valve through the fastening nut, and the lengthened nozzle 2 can be ensured to pass through the fixed nozzle 1;
a through hole is formed in the middle of the sealing rubber ring 3, the diameter of the through hole is larger than the outer diameter of the external thread 5 and smaller than the outer diameter of the annular gasket 6, so that the bottom of the lengthened nozzle 2 penetrates through the sealing rubber ring 3 and is fixed with the annular gasket 6 through the external thread 5;
the bottom of the fixed nozzle 1 is provided with a flat-bottom nozzle, and the bottom of the lengthened nozzle 2 is provided with a conical nozzle, so that the lengthened nozzle 2 can better penetrate into a deep hole for dispensing;
leave 0.5 mm's clearance between external screw thread 5 and the annular gasket 6, thereby leave the clearance and make annular gasket 6 and external screw thread 5 cooperate when fixing on fixed nozzle 1 inner wall, can cooperate with sealing rubber ring 3, can not cause the phenomenon of jam.
Example (b): when connecting extension nozzle 2 on fixed nozzle 1, at first put into the bottom of extension nozzle 2 from fixed nozzle 1's top, the bottom of extension nozzle 2 passes sealed rubber ring 3 and stretches out from fixed nozzle 1's bottom, make internal thread 4 and external screw thread 5 cooperate, rotatory extension nozzle 2 makes extension nozzle 2 fasten the inner wall at fixed nozzle 1, 6 pressfittings of annular gasket are on sealed rubber ring 3 simultaneously, thereby guarantee the leakproofness that fixed nozzle 1 and extension nozzle 2 are connected, install fixed nozzle 1 after connecting and directly use at the injection valve disk seat.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
