Description

The false proof valve body of antifake device

Technical field

The utility model relates to the false proof valve body of a kind of antifake device.

Background technology

At Under the market economy condition, because others' product counterfeit drops into little, profit is large, therefore some illegal manufacturers are large to some markets, profit is high, the famous brand name of the easy manufacturing is copied without restraint, not only compromise the interests of famous brand and customer, and upset market order, make us abhoring.Therefore, hitting fake and forged commodity is the important means safeguarded economic order, ensure consumer legitimate right, hits fake and forged, not only to rely on the effort of government department, what is more important will be taken precautions against from source, and manufacturing enterprise will take measures, and prevents the product of oneself from being emitted by people's puppet.For drinks production, manufacturer is in order to prevent the brand of oneself counterfeit by people, numerous and confused from bottle profile, bottle stopper, the aspects such as anti-counterfeiting mark are carried out omnibearing false proof, but still it is hard to guard against, on the surface all concentrating on bottle due to bottled product false proof of current canned liquid class and bottle stopper, therefore lawless person is undertaken counterfeit by the method again filling to this type of Product recycling bottle, ordinary consumer cannot identify these type of counterfeit and shoddy goods profile, therefore, for in a kind of bottle being convenient to identify of this type of bottled product design, false proof device just seems very necessary.

Utility model content

The technical problems to be solved in the utility model is: based on the problems referred to above, provides antifake device false proof valve body.

The utility model solves the technical scheme that its technical matters adopts: the false proof valve body of a kind of antifake device, comprise valve body, be covered on the valve gap above valve body, be installed on the spool of valve body inner bottom part, being provided with above body cavity can the snap close of up-and-down movement, valve gap central authorities offer the through hole passed for snap close up-and-down movement, snap close bottom is arranged with lock pin frame, in lock pin frame, lock pin is installed, valve body side opening is provided with opening, two symmetrical contrary settings of lock pin, lock pin spring lock pin being ejected valve body is installed in the chamber of two lock pins, the valve body lumenal levels of lock pin spring both sides is provided with the lock dog clamped by lock pin, stepped latch is provided with the Side symmetrical of the lock dog of lock pin clamping, two latches form interior narrow outer wide draw-in groove, the lock dog spring controlling its inside and outside motion is provided with in lock dog.

Further, lock dog spring is V-shaped.

Further, the track being convenient to lock pin movement is provided with in lock pin frame.

Further, latch is that low inside and high outside chevron is symmetrical.

The beneficial effects of the utility model are: bottleneck tightly pins by false proof valve body, and this locking effect has stopping function, does not have invertibility, enhances antiforge function; Stair-stepping latch makes draw-in groove have different width, thus is adapted to the bottleneck of different in width, uses extensively.

Detailed description of the invention

By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.

The false proof valve body of a kind of antifake device as shown in Figures 1 to 3, comprise valve body 10, be covered on the valve gap 19 above valve body 10, be installed on the spool 11 of valve body 10 inner bottom part, being provided with above valve body 10 inner chamber can the snap close 14 of up-and-down movement, valve gap 19 central authorities offer the through hole passed for snap close 14 up-and-down movement, snap close 14 bottom is arranged with lock pin frame 20, lock pin 15 is installed in lock pin frame 20, valve body 10 side opening is provided with opening, two symmetrical contrary settings of lock pin 15, the lock pin spring 16 lock pin 15 being ejected valve body 10 is installed in the chamber of two lock pins 15, valve body 10 lumenal levels of lock pin spring 16 both sides is provided with the lock dog 17 clamped by lock pin 15, stepped latch is provided with the Side symmetrical of the lock dog 17 of lock pin 15 clamping, two latches form interior narrow outer wide draw-in groove, the lock dog spring 21 controlling its inside and outside motion is provided with in lock dog 17.

Lock dog spring 21 is V-shaped, under the effect of lock dog spring 21, and lock dog 17 and lock pin 15 tight clamping fit.

The track being convenient to lock pin 15 movement is provided with in lock pin frame 20.

Latch is that low inside and high outside chevron is symmetrical, makes the outwardly directed length of lock pin 15 different, to adapt to the bottleneck of various sizes.

Bottleneck is arranged on after in antifake device, drive snap close 14 upwards lifting, lock pin 15 is under the effect of lock pin spring 16, eject from the outward opening of valve body 10 side, bottleneck inwall both sides are locked by two lock pins 15, and lock dog spring 21 promotes lock dog 17 and moves to the inside, and lock pin 15 is fixedly clamped by two lock dogs 17 from the side, lock pin 15 is closely engaged with bottleneck inwall, and prevents lock pin 15 from inwardly retreating.

As shown in Figure 4, during finished product state, the end of lock pin 15 is positioned on the narrowest platform of the draw-in groove of lock dog 17; As shown in Fig. 5 ~ 7, during practical set, after bottleneck is loaded, due to snap close 14 upwards lifting, lock pin 15 moves laterally along track and blocks bottleneck in lock pin frame 20, meanwhile, lock dog 17 is under lock dog spring 21 acts on, to the motion of lock pin spring 16 direction and the end clamping of lock pin 15, now, lock pin 15 is stuck in the stair-stepping latch of lock dog 17, thus bottleneck is pinned, and this locking effect has stopping function, does not have invertibility, enhances antiforge function.Stair-stepping latch makes draw-in groove have different width, thus is adapted to the bottleneck of different in width, uses extensively.

With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
