Needle core is guided when being inserted into hose, and can rivet be set in hose, so that direction can be accurately positioned in needle core in hose, is also protected soft
Pipe is not destroyed by needle core.
Utility model content
Therefore, the technical problem to be solved by the present invention is to provide a kind of structure is simple, securely and reliably, can accurately draw
Guide pin core passes through the metal wedge rivet of hose.
A kind of metal wedge rivet, be arranged in remaining needle hose and flexible tube base junction, including with the flexible tube base inner wall
The first part of adaptation, and be inserted into the hose and be suitable for the second part that needle core passes through.
Preferably, the rivet is funnel-shaped.
Preferably, the angle on the two opposite sides side of the first part is 65 ° -95 °.
Preferably, the junction of the first part and second part is arc transition section.
Preferably, the one end of the second part far from the first part is arc structure.
Preferably, the rivet is stainless steel integrated molding.
Technical solutions of the utility model have the advantages that
1. hose and the flexible tube base junction of remaining needle is arranged in metal wedge rivet provided by the utility model, including
The first part being adapted to flexible tube base inner wall, and insertion hose and the second part passed through suitable for needle core；The first of above-mentioned rivet
Part is avoided that needle core contacts before being inserted into hose with flexible tube base, pokes flexible tube base, while needle core being guided to enter hose, second
Dividing can accurately guide needle core to pass through hose, while needle core being avoided to contact during passing through hose with needle core；Above-mentioned rivet
Structure is simple, securely and reliably, and needle core can accurately and effectively be guided to pass through hose, complete human injection, while can also protect and stay
Needle is set not destroyed by needle core.
2. the junction of metal wedge rivet provided by the utility model, first part and second part is arc transition section；
Above structure has embodied the hommization of design, enhances the ornamental value of appearance, rivet can be made more to be bonded with remaining needle.
3. metal wedge rivet provided by the utility model, the one end of second part far from first part is arc structure；On
Stating structure can prevent from scratching remaining needle when installation rivet, can also scratch manpower.
Detailed description of the invention
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art
Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, it is described below
In attached drawing be that some embodiments of the utility model are not paying creativeness for those of ordinary skill in the art
Under the premise of labour, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of rivet provided by the utility model；
Fig. 2 is the cross-sectional view of rivet shown in FIG. 1；
Description of symbols: 1- first part, 2- second part, 21- arc structure, 3- arc transition section.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
Metal wedge rivet as depicted in figs. 1 and 2, is arranged in hose and the flexible tube base junction of remaining needle, and needle core is
Be inserted into from the flexible tube base to the hose direction, the hose Yu the junction of the flexible tube base caliber by the hose
Seat is shunk to the hose direction, and the rivet includes the first part 1 being adapted to the flexible tube base inner wall, and insertion is described soft
Pipe and the second part 2 passed through suitable for needle core.
The first part 1 of above-mentioned rivet be avoided that the needle core before being inserted into the hose with the hose seated connection
Touching, pokes the flexible tube base, while the needle core being guided to enter the hose, and the second part 2 can accurately guide described
Needle core passes through the hose, while the needle core being avoided to contact during passing through the hose with the needle core；Above-mentioned riveting
Pin structure is simple, securely and reliably, and the needle core can accurately and effectively be guided to pass through hose, complete human injection, while also can
The remaining needle is protected not destroyed by needle core.
In addition, the rivet has different several specifications, mainly using the caliber change of the second part 2 described in
The division of rivet specification, and according to the choice of diameter of the needle core and the matched rivet of the needle core.
