Description

Technical Field

[0001] The utility model relates to the technical field of air detection, in particular to an air quality detection storage device. Background Art

[0002] Air samplers are needed in industrial production to detect the air pollution index. When the concentration of the measured component in the air is high, or the sensitivity of the analysis method used is high, a small amount of air sample can be taken by direct sampling to meet the analysis needs. Direct sampling methods mainly include syringe sampling and plastic bag sampling.

[0003] In syringe sampling, since the syringe is mainly composed of a barrel, a piston and a handle, after the air is extracted, the handle protrudes, which is inconvenient to carry. Therefore, in the patent publication number CN212048516U "An air sample storage box", a position for storing the syringe is set, and the barrel and handle of the injection liquid are fixed, but the barrel of the syringe is not improved. The handle of the syringe sampler itself protrudes, which is still inconvenient to carry, and the wear of the piston and the shaking of the handle can easily cause the syringe sampler to leak. That is, the existing syringe sampler has a poor sealing effect. When used in air detection and storage, it needs to go out for sampling and placement. The poor sealing effect will affect the final detection result, so the structure needs to be improved. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an air quality detection storage device to solve the problem that the handle of the syringe sampler itself is protruding and inconvenient to carry.

[0006] An air quality detection storage device includes a storage cylinder, a cone head is fixedly connected to the left side of the storage cylinder, a switch valve is arranged on the cone head, a hand-tightened bolt is arranged on the switch valve, a piston is movably connected to the inside of the storage cylinder, a rope is connected to the right side of the piston, a sealing cover is connected to the end of the rope, and the sealing cover corresponds to the storage cylinder.

[0007] Preferably, the right side of the piston is fixedly connected to a support frame, the support frame is provided with an opening, and the rope is connected to the opening.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] like Figure 1 - Figure 2As shown, the utility model provides an air quality detection storage device, including a storage cylinder 1, a cone head 2 is fixedly connected to the left side of the storage cylinder 1, a switch valve 3 is arranged on the cone head 2, a hand-tightened bolt 4 is arranged on the switch valve 3, a piston 5 is movably connected inside the storage cylinder 1, a rope 6 is connected to the right side of the piston 5, a sealing cover 7 is connected to the end of the rope 6, and the sealing cover 7 corresponds to the storage cylinder 1.

[0019] The syringe sampler is improved. Since it is used for air quality detection, more attention is paid to the storage function of air. Since sampling needs to be carried out, it needs to be designed to be more portable. By replacing the handle rod with a rope 6, when sampling, the hand-tightening bolt 4 can be twisted to open the switch valve 3. By pulling the sealing cover 7, the rope 6 can be easily pulled, thereby driving the piston 5 to extract air. After the extraction is completed, the sealing cover 7 can be covered on the storage tube 1. The sealing cover 7 and the piston 5 form a double seal, which can better preserve the sampled air. Since absolute leakage is inevitable, this setting is more sealed than the original scheme, which prolongs the storage time of the sampled air and is beneficial to the accuracy of air quality detection. At the same time, the switch valve 3 is closed to complete the sampling. There is no protruding handle rod, which is more convenient to carry. The sampled air needs to be taken out only during detection, and the rod body can be used in the detection room to push the piston 5 to push the air out.

[0020] The right side of the piston 5 is fixedly connected with a support frame 8, and an opening 9 is provided on the support frame 8, and the rope 6 is connected to the opening 9. The support frame 8 strengthens the support of the piston 5, and the opening 9 provided at the same time facilitates the connection of the rope 6.

[0021] The outer side of the storage barrel 1 is provided with an external thread 10, the inner side of the sealing cap 7 is provided with an internal thread 11, the external thread 10 and the internal thread 11 are correspondingly threadedly connected, and a sealing gasket 12 is provided inside the sealing cap 7. The internal thread 11 and the internal thread 11 can be threadedly connected, so that the sealing cap 7 can be threadedly installed on the storage barrel 1, and the sealing gasket 12 is used to strengthen the seal.

[0022] The right side of the sealing cover 7 is fixedly connected with a base 13. When placed in the detection room, the base 13 can be placed on a work surface. The base 13 has a large area and can play a role in stable placement. A suction cup can also be provided at the bottom of the base 13 to further improve the stability effect and prevent the storage tube 1 from rolling and falling.

[0023] Working principle: When in use, manually twist the hand screw 4 to open the switch valve 3. By pulling the sealing cover 7, the rope 6 can be easily pulled, thereby driving the piston 5 to extract the air. After the extraction is completed, the sealing cover 7 can be covered on the storage tube 1. By rotating the sealing cover 7 for threaded installation, a double seal is formed with the piston 5 under the action of the sealing gasket 12. At the same time, the switch valve 3 is closed to complete the sampling. After the sampling is completed, it can be placed in a storage bag and taken out when it is needed for testing. The bases 13 of multiple devices can be placed on the workbench in turn, and one of the storage devices can be taken. The switch valve 3 and the sealing cover 7 are opened, and the piston 5 is pushed by the rod to discharge the sampled air.

[0024] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
