Description
Technical Field
The utility model relates to a sample collection bag, it belongs to sample sampling utensil field.
Background
In the sample detection work, the collection of various samples is very important basic work, the sample collection is a basic stone for analysis and test, and the analysis and test are carried out after the sampling to obtain related information and data, so that important basis is provided for later research and judgment. Therefore, the quality and representativeness of sample sampling directly influence the next working deployment, but some sample collection bags on the market still have defects, and the Chinese utility model with the publication number of CN203479573U has the following two defects that the first collection bag can only hold the bag mouth with the hand when collecting liquid, especially collecting dirty sewage, but fingers need to be inserted into water, and then the operation is carried out by wearing gloves, which brings inconvenience to the operation; secondly, this kind of collection bag can only gather solid and liquid, can not gather gas (gather gas and be used in public environment, workshop and laboratory at present, squeeze into the sampling bag after collecting through the air pump basically, at last seal the sack again, reach the purpose of gathering), therefore the enterprise need purchase solid-liquid respectively and gather the bag with gaseous two kinds, purchase two kinds and gather the bag and not only brought very big trouble to the operator, also increased the purchasing cost of enterprise. There is therefore a need for a new type of sample collection bag.
SUMMERY OF THE UTILITY MODEL
The utility model provides a sample collection bag aiming at the defects existing in the prior art.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
the utility model provides a sample collection bag, includes the bag body, and fixedly connected with exposes the screw thread mouth of the bag body two to four centimetres on the bag body, is equipped with the lid on the screw thread mouth, and the inner wall of lid is equipped with the internal thread first with the external screw thread threaded connection of screw thread mouth, be equipped with the sealing plug in the screw thread mouth, the center of sealing plug is equipped with the inlet port.
Preferably, the inner wall of the threaded opening is provided with an internal thread B, and the outer wall of the sealing plug is provided with an external thread A in threaded connection with the internal thread B.
Preferably, the outer wall of the bag body is provided with a handheld air bag.
Preferably, the shape of the handheld air bag is an arc-shaped structure.
Preferably, the sealing plug is made of rubber or silica gel.
Preferably, a through hole is further formed beside the handheld air bag.
Compared with the prior art, the beneficial effects of the utility model are that: firstly, the sealing plug is arranged on the threaded opening of the utility model, the sampled gas can be pumped into the bag through the air inlet hole on the sealing plug to complete the gas sampling, in addition, the sealing plug is made of rubber or silica gel and has elasticity, so that the sealing plug can be restored to a closed state, the gas in the bag can not be discharged out by itself without the interference of external force, and the sealing performance is good; secondly, the outer wall of the bag body is provided with a handheld air bag, so that an operator can conveniently wear gloves to collect sewage; thirdly, the utility model can collect liquid, fixed and gas, which not only facilitates the operation of operators, but also reduces the cost of enterprises; fourthly, a through hole is formed beside the handheld air bag, so that when water in a river or a sewage pool is collected, a bag body can be conveniently fixed by penetrating the through hole through a tool such as a hook, and then the collection bag is stretched into the river or the sewage pool for collection operation; and a counterweight (such as a weight) can be hung through the through hole, so that the sampling bag can realize the purpose of deep sampling.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, a bag body; 11. a hand-held airbag; 12. a through hole; 2. a cover body; 3. a sealing plug; 31. an air inlet; 4. and (4) opening the thread.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, a sample collection bag comprises a bag body 1, wherein a threaded opening 4 of two to four centimeters is fixedly connected to the bag body 1, the bag body 1 is exposed out of the threaded opening 4, a cover body 2 is arranged on the threaded opening 4, an internal thread A in threaded connection with an external thread of the threaded opening 4 is arranged on the inner wall of the cover body 2, a sealing plug 3 is arranged in the threaded opening 4, and an air inlet 31 is arranged in the center of the sealing plug 3.
The inner wall of the threaded port 4 is provided with an internal thread B, and the outer wall of the sealing plug 3 is provided with an external thread A in threaded connection with the internal thread B.
The outer wall of the bag body 1 is provided with a handheld air bag 11.
The shape of the handheld air bag 11 is an arc structure.
The sealing plug 3 is made of rubber or silica gel.
A through hole 12 is arranged beside the handheld air bag 11.
The utility model discloses a theory of operation:
when gas is collected, the sampled gas is injected into the bag body 1 through the gas needle tube, the gas inlet 31 can be opened by the huge pressure of the gas needle, after the gas is collected, the gas needle tube is pulled out, and the sealing plug 3 is made of rubber or silica gel and has elasticity, so that the sealing plug 3 can be restored to a tight state, and the gas in the bag body 1 cannot be discharged by itself without the interference of external force; when solid or liquid needs to be collected, the sealing plug 3 is only required to be unscrewed.
