Description
Technical field
The utility model relates to a kind of rapid-acting coupling sampler of sealing.
Background technology
At present, the airtight container that some packing special liquids are arranged on the market, its staving top is provided with bottom insert canal and snorkel, the sub-tooth of rapid-acting coupling all is set on bottom insert canal and the snorkel, the sub-tooth of rapid-acting coupling seals when not using, if want to take out the liquid of can in the staving, this just needs necessary instrument, or the sealing bung of the bucket of need unpacking, opening from the staving takes out liquid again, but this sampling under open environment just causes special liquid to be polluted easily, even causes security incident.Thereby safe and efficient taking-up sample and guarantee the not contaminated key that just becomes sampling of special liquid under air-proof condition how.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and can conveniently take out the packing liquid in bucket under the condition of sealing, can avoid liquid to be polluted or the rapid-acting coupling sampler of the sealing of security incident takes place.
The technical scheme that the utility model adopted is: the utility model comprises the female tooth of rapid-acting coupling, auxiliary joint, nut and self elastic diaphragm seal, the centre of described auxiliary joint is provided with through hole, described nut is provided with the major thread hole, the aperture that communicates with described major thread hole, described aperture is positioned at the position relative with described through hole, one end of described auxiliary joint is connected with the female pitch thread of described rapid-acting coupling, and described through hole communicates with the female tooth of described rapid-acting coupling, the other end is threaded with described major thread hole, described diaphragm seal is positioned at described major thread hole and is held out against on described nut by described auxiliary joint, and described diaphragm seal seals up described through hole.
Described diaphragm seal is silica gel sheet or butyl film or butyronitrile film or neoprene sheet.
The cross section of described auxiliary joint exposed parts is regular polygon or triangle or irregularly shaped.
The beneficial effects of the utility model are: the utility model comprises the female tooth of rapid-acting coupling, auxiliary joint, nut and self elastic diaphragm seal, the centre of described auxiliary joint is provided with through hole, described nut is provided with the major thread hole, the aperture that communicates with described major thread hole, described aperture is positioned at the position relative with described through hole, one end of described auxiliary joint is connected with the female pitch thread of described rapid-acting coupling, and described through hole communicates with the female tooth of described rapid-acting coupling, the other end is threaded with described major thread hole, described diaphragm seal is positioned at described major thread hole and is held out against on described nut by described auxiliary joint, described diaphragm seal seals up described through hole, on the sub-tooth of the rapid-acting coupling by the female tooth of described rapid-acting coupling being arranged on pail pack, can conveniently emit special liquid, and described diaphragm seal and described nut are blocked in special liquid in female tooth of described rapid-acting coupling and the described through hole, then the syringe needle by syringe inserts described diaphragm seal draw samples, after extracting syringe, described diaphragm seal is closed pin hole under the effect of self elastic force, avoided the unpacking sealing bung of bucket, opening from the staving is emitted special liquid again, special liquid is because of touching air and go bad even causing security incident, so the utility model can conveniently take out the packing liquid in bucket under the condition of sealing, can avoid liquid to be polluted or take place security incident.
