Abstract
The invention relates to a syringe needle for a trunk injector, and the syringe is characterized in that a main body is made of a metallic material, wherein a guide thread is formed at one end of the main body; an injection hole is formed on the middle part of the main body; the injection hole is communicated with the exterior of the tip part of the main body; a sealing ring is mounted in a circular slot in the middle of a sealing cover; the sealing cover is mounted on the exterior circle of the main body; and an adjusting bolt is mounted on the exterior circle of the main body in a screw-thread fit manner. In a use process, the main body is firstly inserted into a trunk through the guide thread at one end of the main body and the adjusting bolt is tightened up after the main body is inserted for a certain depth; then the sealing ring is mounted in the circular slot in the middle of the sealing cover and the sealing cover is mounted on the exterior circle of the main body; and finally, the adjusting bolt is mounted on the exterior circle of the main body in a screw-thread fit manner and the sealing cover is covered into bark.
Description
Technical field
The present invention relates to a kind of structure of injection needle, particularly a kind of trunk injection eedle head belongs to agricultural protection field of mechanical technique.
Background technology
The trunk injection medicament is a kind of new technology that prevents the trees damage by disease and insect, it is fast to have desinsection, the efficient height, the advantage that drug effect is permanent, but, existing syringe needle structurally is the structure of an integral body, that is: fix as the cutting edge and the main part of hermetic unit, though such structure has advantage of simple structure, but, because it is the structure of fixing that hermetic unit and main part are arranged, sealing is thrust trunk to syringe needle and is played inhibition, syringe needle can't thrust proper depth according to specific circumstances, can't reach best injection effect, has reduced the result of use of medicament.
Summary of the invention
The objective of the invention is to: a kind of trunk injection eedle head is provided, overcome existing trunk injection eedle head owing to adopt whole version existing: syringe needle can't thrust proper depth according to specific circumstances, can't reach best injection effect, reduce the defective of medicament result of use.
The present invention realizes that the technical method that above-mentioned purpose adopts is: select metal material for use, make main body, and the while produces the importing screw thread, produces injection orifice in the centre at an end of main body, and make the exterior of the pointed portion of injection orifice and main body, sealing ring is installed in the middle cannelure of seal cover, seal cover is installed on the cylindrical of main body, the adjusting bolt is installed in above the cylindrical of main body by the mode of threaded engagement again; During work, at first the importing screw thread of main body by the one end thrust it in trunk, after arriving certain degree of depth, tighten the adjusting bolt, sealing ring is installed in the middle cannelure of seal cover, seal cover is installed on the cylindrical of main body, bolt is installed in above the cylindrical of main body by the mode of threaded engagement again, and seal cover fastens in the bark.
Beneficial effect: the present invention is owing to make the version of split with hermetic unit and main body, and by regulating the mode of bolt position on main body, the main part of controlling syringe needle is thrust the formula of doing of the trunk degree of depth, so, a kind of trunk injection eedle head of the present invention, can be according to concrete needs, the optimum depth of trunk is thrust in selection, improve the result of use of medicament, effectively overcome above-mentioned existing syringe needle and can't thrust proper depth according to specific circumstances, can't reach best injection effect, reduce the defective of medicament result of use.
