SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a closing device of laboratory gas sampling bladder has solved inconvenient, the centre gripping firm inadequately and the tight scheduling problem of centre gripping on the support.

In order to satisfy the above-mentioned purpose, the utility model discloses the technical scheme who takes does:

the utility model provides a closing device of gaseous sample bladder in laboratory, is including card post and draw-in groove, the rotation axis swivelling joint is passed through to the one end of card post and draw-in groove, be equipped with locking structure on the other end of card post and draw-in groove, card post and draw-in groove merge the back and act on the department of sealing of gaseous sample bladder.

Preferably, the central position of the clamping column is provided with a clamping column protrusion, the central position of the clamping groove is provided with a clamping groove, and the clamping column protrusion is matched with the clamping groove.

Preferably, the locking structure includes two fastening ends, two the fastening end is located card post and draw-in groove one end respectively, be equipped with the bolt hole on the fastening end, the bolt hole phase-match on two fastening ends.

Preferably, the clamping column protrusion is of a cuboid or triangular prism structure.

Preferably, the clamping columns and the clamping grooves are made of plastic, iron or alloy.

Preferably, a hanging ring is arranged at the joint of the clamping column and the clamping groove.

The utility model has the advantages that:

this closing device is through the ingenious design of card post and draw-in groove and its card post arch and draw-in groove recess, just can grasp the sealing of gaseous sample bladder, the other end of rethread locking structure fastening card post and draw-in groove, reach sealed firm inadequately and sealed not tight effect, locking structure is the bolt or the buckle structure that can dismantle at any time simultaneously, the centre gripping is more convenient during the experiment, time saving and labor saving, it does not tightly cause gas leakage because of tying up to have reduced, hang to bladder strorage device with the help of the buckle, save real laboratory space.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of example 2;

in the figure: 1. the caliper comprises a clamping column, 2 clamping grooves, 3 rotating shafts, 4 clamping column protrusions, 5 clamping groove grooves, 6 bolt holes, 7 fastening ends, 8 suspension rings, 9 caliper male fasteners and 10 caliper female fasteners.

Detailed Description

The invention will be further described with reference to the accompanying drawings and working principles:

as shown in fig. 1 a sealing device of laboratory gas sampling bladder, including card post 1 and draw-in groove 2, the one end of card post 1 and draw-in groove 2 is passed through rotation axis 3 swivelling joint, the link of card post 1 and draw-in groove 2 can be rotatory round the rotation axis, be equipped with locking structure on the other end of card post 1 and draw-in groove 2, its purpose can lock when cliping gas sampling bladder between card post 1 and draw-in groove 2 and seal, play sealed effect, card post 1 and draw-in groove 2 merge the back and act on the sealed gas sampling bladder of department of sealing of gas sampling bladder. Card 1 central point of post puts and is equipped with card post arch 4, and the central point of draw-in groove 2 puts and is equipped with draw-in groove recess 5, and card post arch 4 and draw-in groove recess 5 phase-matches, and its optimum card post arch 4 and draw-in groove recess 5 are assorted triangular prism, and the triangular prism structure leakproofness that hugs closely each other is optimum, and is sealed most closely. Locking structure includes two fastening ends 7, two fastening ends 7 are located card post 1 and draw-in groove 2 one end respectively, be equipped with bolt hole 6 on the fastening end 7, 6 phase-matchs in the bolt hole on two fastening ends 7, after card post 1 and draw-in groove 2 centre gripping gas sampling bladder, utilize bolt hole 6 to pass through bolted connection with two fastening ends 7 again, the convenience is untied when examining, the junction of card post 1 and draw-in groove 2 is equipped with hangs ring 8, be used for hanging behind the sealed gas sampling bladder of the device on the strorage device support of laboratory gas sampling bladder.

Example 1

When using the device, at first will seal the gaseous ball bladder of taking a sample of gathering and arrange in between card post 1 and draw-in groove 2, make card post arch 4 enter into draw-in groove recess 5 through the rotatory card post 1 of rotation axis 3, tightly clip the gaseous ball bladder of taking a sample and seal, then utilize bolt hole 6 to pass through the bolt-up with two fastening ends 7, reach the effect of fastening, then say the device again and hang on the strorage device support of the gaseous ball bladder of laboratory through hanging ring 8.

Example 2

The device is the plastics material optimally, as shown in fig. 2, set the locking structure into slide caliper rule pin thread 9 and slide caliper rule box 10, when the sealed gas sampling bladder after gathering gas is sealed, only need card post 1 and draw-in groove 2 rotatory centre gripping back, press slide caliper rule pin thread 9 and slide caliper rule box 10 hard, with slide caliper rule pin thread 9 and slide caliper rule box 10 closed, because the plastics material has plasticity, the closure is opened and is all can be realized, just can reach the sealed effect of centre gripping, this kind of clamping device uses more conveniently.
