Utility model content
In consideration of it, the utility model provides a kind of nozzle connection for pencil that can effectively improve sealing performance
Structure and pencil.
Thus, on the one hand, the utility model provides a kind of nozzle connection structure for pencil comprising pipe lid, pipe
Lid is connected on the nozzle of tube body, and pipe lid has top plate, and the bottom of top plate is connected with sealing plate, and sealing plate is circular slab, sealing
The lateral surface of plate has toothed surface, offers annular groove on the inner wall of nozzle, and the ring with toothed surface cooperation is provided on annular groove
Shape flange collar, the bottom of sealing plate are fixedly connected with plunger, and the bottom of plunger extends into tube body.
Further, above-mentioned annular bead includes be arranged successively along the axial direction of nozzle from the top of nozzle to bottom
One flange collar unit and the second flange collar unit.
Further, above-mentioned first flange collar unit and toothed surface cooperate.
Further, above-mentioned first flange collar unit has the first cambered surface, and the first cambered surface and toothed surface cooperate.
Further, above-mentioned second flange collar unit has the second cambered surface, and the second cambered surface is towards plunger direction.
Further, symmetrically arranged two groove body is offered in above-mentioned second cambered surface.
Further, above-mentioned groove body radially extending along the second cambered surface.
On the other hand, the utility model provides a kind of pencil, including tube body, it is characterised in that: further includes above-mentioned one
Kind is used for the nozzle connection structure of pencil.
A kind of nozzle connection structure and pencil for pencil provided by the utility model, leads compared to the prior art
The cooperation using toothed surface on sealing plate and annular bead is had the advantage that, so that bottle cap can use tooth in pressing
The effect in shape face circumferentially water conservancy diversion outward by air, so that air cannot be introduced into tube body, so as to effectively mention
The sealing performance of high pencil.
Detailed description of the invention
By reading the following detailed description of the preferred embodiment, various other advantages and benefits are common for this field
Technical staff will become clear.The drawings are only for the purpose of illustrating a preferred embodiment, and is not considered as practical to this
Novel limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings:
