Heparin tube nut cap mainly includes the first lid 100 and the second lid 200, and the first lid 100 and the second lid 200 are It for hollow structure and is to be integrally formed, in order to keep the connection relationship between nut cap and rubber plug 300 relatively stable, therefore first First limit assembly 10 and the second limit assembly 20 are set on the inner wall of lid 100, in the present embodiment, optional first limit group Part 10 and the second limit assembly 20 are positive stop strip 11, and positive stop strip 11 circularizes, and are mounted on 100 inner wall one of the first lid circle, In order to achieve the effect that centainly to prevent rubber plug 300 from falling off, therefore the width of the positive stop strip 11 of the second limit assembly 20 is the first limit The brightness of 11 width of positive stop strip of hyte part 10, so that rubber plug 300 is not easy to skid off from nut cap when taking out heparin tube.

In order to keep the frictional force between positive stop strip 11 and rubber plug 300 bigger, therefore at the free end end face of positive stop strip 11 Provided with protrusion, and in the present embodiment, the shape of optional protrusion is semicircle or triangle.

The heparin tube nut cap of the utility model setting, by the way that 10 He of the first limit assembly is arranged in 100 inner wall of the first lid The top of 100 inner wall of the first lid is arranged in second limit assembly 20, the first limit assembly 10, and primarily serving prevents rubber plug 300 It skids off upwards, the bottom end of 100 inner wall of the first lid is arranged in the second limit assembly 20, and primarily serving prevents rubber plug 300 to downslide Out, it is acted synergistically by the first limit assembly 10 and the second limit assembly 20, to make connection between rubber plug 300 and nut cap more Be it is close, play the generation for preventing " raising one's hat " phenomenon.

In order to make the present apparatus convenient for operation, therefore also set up at the outer wall of the second lid 200 inner multiple outwardly protrude Perpendicular rib 201.

Embodiment 2:

A kind of heparin tube nut cap, the first lid 100 and the second lid 200 including being hollow structure, first lid 100 inner wall of body is equipped with the first limit assembly 10 and the second limit assembly 20, and first limit assembly 10 is set to first lid One end of 100 inner wall of body, second limit assembly 20 are set to the other end of 100 inner wall of the first lid, and described second Limit assembly 20 is close to second lid 200.

Further, first limit assembly 10 and second limit assembly 20 include locating part 21 and card-bit part 22, the locating part 21 includes the first limited block 211 and the second limited block 212, is equipped with through-hole in second limited block 212 213, the first limiting slot 214 and the second limiting slot 215, the through-hole 213 and first limiting slot 214 and second limit Slot 215 communicates, and first limiting slot 214 extends to the first limited block 211, and second limiting slot 215 is limited to described second The position free extreme direction of block 212 extends；

The card-bit part 22 includes fastener ontology 221, and the fastener ontology 221 is equipped with and first limiting slot 214 Matched first fixture block 222 and matched second fixture block 223 of second limiting slot 215 and snap-gauge 224, the snap-gauge 224 Set on the both ends of the fastener ontology 221, the snap-gauge 224 extends to nut cap inner cavity.

Further, first fixture block 222 and second fixture block 223 are vertical and described with the fastener ontology 221 First fixture block 222 is parallel to each other with second fixture block 223.

Further, direction is mounted on the fastener ontology 221 first fixture block 222 obliquely downward, and first fixture block Angle between 222 and the fastener ontology 221 is 30~60 °；Second fixture block, 223 oblique direction is mounted on the fastener On ontology 221, and the angle between first fixture block 222 and the fastener ontology 221 is 120~150 °.

Further, direction is mounted on the fastener ontology 221 first fixture block 222 obliquely downward, and first fixture block Angle between 222 and the fastener ontology 221 is 45 °；Second fixture block, 223 oblique direction is mounted on the fastener ontology On 221, and the angle between first fixture block 222 and the fastener ontology 221 is 145 °.

Further, the thickness of the snap-gauge 224 is from gradually becoming smaller, the most thick one end of the snap-gauge 224 and the fastener sheet Body 221 connects.

As shown in Fig. 3~8, in above-described embodiment 1, the first locating part 21 and the second locating part 21 can also be to be to include Locating part 21 and card-bit part 22, and the structure of locating part 21 can be identical as the positive stop strip 11 of above-described embodiment, but in this reality Apply in example, locating part 21 is cyclic shape, and is mounted on 100 inner wall of the first lid, locating part 21 be include the first limited block 211 and second limited block 212, wherein the first limited block 211 primarily serves connection function, 211 one end of the first limited block and nut cap Inner wall connection, the first limit other end are connect with 212 one end of the second limited block.

The middle part of second limited block 212 is provided with the through-hole 213 for passing through the fastener ontology 221 of card-bit part 22, The through-hole 213 also sets up the first limiting slot 214 and the second limiting slot 215, such as shown in figure 3 and 4 on second limited block 212 In figure shown in 3 and 4, the first limiting slot 214 and the second limiting slot 215 are to come round with through-hole 213, and the first limit and second limits The main function of position slot 215 is to make the first fixture block 222 and the limit of the second fixture block 223 on fastener ontology 221, to make to limit Relationship between part 21 and card-bit part 22 is more firm, as shown in FIG. 7 and 8.

Acting predominantly on for card-bit part 22 is set, by the snap-gauge 224 on fastener ontology 221, further blocks rubber plug 300, increase the stability between rubber plug 300 and nut cap, in the present embodiment, the thickness of optional snap-gauge 224 is to gradually become smaller, this The end section for the snap-gauge 224 that sample makes can more preferably act on rubber plug 300, achieve the effect that prevent rubber plug 300 from sliding, such as Figures 5 and 6 institute Show.

It is stronger in order to reach the connection between card-bit part 22 and limited block, therefore to the first fixture block 222 on card-bit part 22 Further restriction is also done with the second fixture block 223, between optional first fixture block 222 and the second fixture block 223 and fastener ontology 221 Setting angle be 90 °, as shown in Figure 3, then optional first fixture block 222 is mounted on obliquely on fastener ontology 221, and install Angle is between 30~60 °, and preferably 45 ° as shown in figure 4, the second fixture block 223 is mounted on fastener obliquely in the present embodiment On ontology 221, and setting angle is 120~150 readings, preferably 145 ° in the present embodiment, passes through and 222 He of the first fixture block is arranged Angle between second fixture block 223 and fastener ontology 221, to obtain more effectively in firm.

The other parts of the present embodiment are identical as above-described embodiment 1, do not repeating.

While there has been shown and described that the embodiments of the present invention, it will be understood by those skilled in the art that Are as follows: these embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective and become Type, the scope of the utility model are defined by the claims and their equivalents.
