Description
Technical Field
[0001] This application relates to the field of gas sampling, and particularly to a gas sample storage device. Background Art
[0002] Gas samples refer to samples of pollutants in the atmosphere or contaminated air samples. There are two types of collection methods. One is to pass a large amount of air through a liquid absorbent or a solid adsorbent to enrich the pollutants with relatively low concentrations in the atmosphere, such as the air extraction method and the filter membrane method. The other is to collect the air containing pollutants using a container.
[0003] When using a container to collect the air of pollutants, the container is basically selected as a glass bottle or a special plastic bag for collection. When using a plastic bag for collection, the plastic bag is generally a sealed bag with a valve installed on it. Gas enters the bag through the valve to inflate the bag, and the collection of the gas sample is completed.
[0004] After collecting the gas sample using a plastic bag, since the plastic bag is in an inflated state, it will expand into an irregular shape. Moreover, the weight of the plastic bag and the gas is relatively light. When moving the plastic bag, the plastic bag is pushed or shaken, and the plastic bags shake back and forth, rubbing against each other, squeezing, and getting damaged, resulting in difficult transportation. Summary of the Utility Model
[0005] The purpose of this application is to solve the problem proposed in the above background art that since the plastic bag is in an inflated state, it will expand into an irregular shape, and the weight of the plastic bag and the gas is relatively light. When moving the plastic bag, the plastic bag is pushed or shaken, and the plastic bags shake back and forth, rubbing against each other, squeezing, and getting damaged, resulting in difficult transportation. This application provides a gas sample storage device.

The limiting mechanism in the storage space clamps and limits the collection bag, making the collection bag firmly located in the storage box. When the limiting mechanism limits the collection bag, it also protects the collection bag, thereby reducing the possibility that the collection bag is not easy to store and move due to its light weight, and reducing the possibility of the collection bag being squeezed and damaged.

[0011] Furthermore, the resistance component includes a resistance plate 1 fixed on the partition plate, a resistance plate 2 is fixed on the clamping plate, and both the resistance plate 1 and the resistance plate 2 are foam plates.
[0012] By adopting the above technical solution, the clamping plate drives the second contact plate to approach the first contact plate on the partition plate, so that the first contact plate and the second contact plate clamp the collection bag, thereby further improving the protection of the collection bag.
[0013] Furthermore, arc grooves are formed on the first and second contact plates.
[0014] By adopting the above technical solution, when the contact plate 1 and the contact plate 2 clamp the collection bag, the arc grooves on the contact plate 1 and the contact plate 2 limit the collection bag, thereby further reducing the possibility of movement of the clamped collection bag.
[0015] Furthermore, the sliding assembly includes two sliding blocks symmetrically fixed on the clamping plate, and sliding grooves corresponding to the sliding blocks are opened on the storage partition and the inner wall of the storage box. The sliding block is located in the sliding groove and is slidably connected to the corresponding storage partition and the inner wall of the storage box.
[0016] By adopting the above technical solution, the clamping plate is moved under the support of the sliding block, so that the clamping plate can be kept stable during the clamping movement.
[0017] Furthermore, the quick fixing mechanism includes two support blocks symmetrically fixed on the storage cover, the support blocks are slidably connected with a snap-in block, the snap-in block is provided with evenly distributed snap-in teeth 1, and the outer walls on both sides of the storage box are provided with evenly distributed snap-in teeth 2, the snap-in teeth 1 and the snap-in teeth 2 correspond to each other and are in opposite directions.

[0019] Furthermore, a clamping spring is arranged between the support block and the engaging block, and both ends of the clamping spring are fixedly connected to the support block and the engaging block.
[0020] By adopting the above technical solution, by using the pushing force of the clamping spring on the engaging block, the engaging teeth I on the engaging block can be firmly engaged with the engaging teeth II on the storage box.
[0021] Furthermore, a pulling rod is fixed on the engaging block, the pulling rod penetrates through the support block and is slidably connected to the support block.
[0022] By adopting the above technical solution, pulling the pulling rod causes the pulling rod to drive the engaging block to slide on the support block, separating the engaging teeth I and the engaging teeth II, so that the storage cover can be conveniently removed from the storage box.
[0023] In summary, the present application includes at least one of the following beneficial effects;
[0024] 1.

[0032] The following is combined with Figure 1 —4 Provide further details of this application.
[0033] The embodiment of the present application discloses a gas sample storage device.
[0034] Reference Figure 1 , Figure 2 and Figure 3 A gas sample storage device comprises a storage box 1, in which a plurality of evenly distributed storage partitions 2 are fixed, the storage partitions 2 divide the storage box 1 into a plurality of storage spaces, a storage cover 3 is arranged on the storage box 1, a limiting mechanism 4 is arranged in the storage space, and a quick fixing mechanism 5 is arranged between the storage cover 3 and the storage box 1.
[0035] When sampling and collecting gas, a gas sampling bag is generally used to directly collect and store the gas. After the gas is collected using the collection bag, the collection bag is placed in the storage box 1 so that the collection bag is located in the storage space separated by the storage partition 2. The limiting mechanism 4 in the storage space clamps and limits the collection bag so that the collection bag is firmly located in the storage box 1. When the limiting mechanism 4 limits the collection bag, the collection bag is also protected. Then the storage cover 3 is covered on the storage box 1. When the storage cover 3 is covered, the storage cover 3 and the storage box 1 are fixed together using the quick fixing mechanism 5. By placing the collection bag with collected gas into the storage box 1 and then limiting and protecting the collection bag using the limiting mechanism 4, the possibility of the collection bag being difficult to store and move due to its lightness can be reduced, and the possibility of the collection bag being squeezed and damaged can be reduced.
[0036] Reference Figure 1 , Figure 2 and Figure 3 The limiting mechanism 4 includes a partition plate 41 arranged in the storage space, the partition plate 41 is fixedly connected to the corresponding storage partition plate 2 and the inner wall of the storage box 1, clamping plates 42 are arranged on both sides of the partition plate 41, and a sliding component 45 is arranged on the clamping plate 42. A clamping spring 43 is arranged between the clamping plate 42 and the inner wall of the storage box 1, and both ends of the clamping spring 43 are fixedly connected to the clamping plate 42 and the storage box 1, and an interference component 44 is arranged between the partition plate 41 and the clamping plate 42.
[0037] In addition, the resistance assembly 44 includes a resistance plate 1 441 fixed on the partition plate 41 , and a resistance plate 2 442 fixed on the clamping plate 42 . Both the resistance plate 1 441 and the resistance plate 2 442 are foam plates.
[0038] In addition, arc grooves are formed on the first contact plate 441 and the second contact plate 442 .
[0039] In addition, the sliding assembly 45 includes two sliding blocks 451 symmetrically fixed on the clamping plate 42, and sliding grooves 452 corresponding to the sliding blocks 451 are opened on the inner walls of the storage partition 2 and the storage box 1. The sliding block 451 is located in the sliding groove 452 and is slidably connected to the corresponding storage partition 2 and the inner wall of the storage box 1.
[0040] When placing the gas collection bag into the storage space in the storage box 1, first pull the clamping plate 42 to make it slide under the support of the sliding block 451. The clamping block simultaneously squeezes the clamping spring 43. Then, place the collection bag between the partition plate 41 and the clamping plate 42. Then release the clamping plate 42. Under the push of the clamping spring 43, the clamping plate 42 drives the second abutting plate 442 to approach the first abutting plate 441 on the partition plate 41. The first abutting plate 441 and the second abutting plate 442 clamp the collection bag, and the arc grooves on the first abutting plate 441 and the second abutting plate 442 limit the collection bag. By placing the collection bag filled with gas between the partition plate 41 and the clamping plate 42, and then using the clamping spring 43 to push the clamping plate 42, the first abutting plate 441 and the second abutting plate 442 clamp the collection bag, so as to facilitate the fixed clamping of the collection bag, reduce the possibility of the collection bag moving in the storage box 1, and reduce the possibility of the collection bag being damaged by excessive extrusion during transportation.
[0041] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.
[0042] In addition, a clamping spring 55 is arranged between the support block 51 and the clamping block 52, and both ends of the clamping spring 55 are fixedly connected to the support block 51 and the clamping block 52.
[0043] Moreover, a pulling rod 56 is fixed on the clamping block 52. The pulling rod 56 passes through the support block 51 and is slidably connected to the support block 51.
[0044] After all the collection bags are put into the storage box 1, and the collection bags are clamped and limited by the contact plate 1 441 and the contact plate 2 442, the storage cover 3 is aligned with the storage box 1, and then the storage cover 3 is directly pressed down to make the inclined surfaces of the engaging teeth 1 53 on the engaging block 52 and the engaging teeth 2 54 on the storage box 1 slide against each other, and at the same time, the engaging block 52 slides in the supporting block 51 and squeezes the engaging spring 55. When the storage cover 3 is completely covered on the storage box 1, the engaging teeth 1 53 on the engaging block 52 and the engaging teeth 2 54 on the storage box 1 are locked under the push of the engaging spring 55. Together, the storage cover 3 and the storage box 1 are fixed together. When the storage cover 3 needs to be separated from the storage box 1, the pulling rod 56 is directly pulled to allow the pulling rod 56 to drive the clamping block 52 to slide on the supporting block 51, so that the clamping tooth 1 53 and the clamping tooth 2 54 are separated, and then the storage cover 3 is removed. By allowing the storage cover 3 to directly cover the storage box 1, the clamping tooth 1 53 on the clamping block 52 and the clamping tooth 2 54 on the storage box 1 are clamped together, so that the storage cover 3 can be conveniently and quickly fixed to the storage box 1, and the storage cover 3 can protect the collection bag in the storage box 1.
[0045] Working principle: When sampling and collecting gas, a gas sampling bag is generally used to collect and store the gas directly. After the gas is collected using the collection bag, the collection bag is placed in the storage box 1, the clamping plate 42 is pulled, and the clamping plate 42 is allowed to slide under the support of the sliding block 451. The clamping block squeezes the clamping spring 43 at the same time, and then the collection bag is placed between the partition plate 41 and the clamping plate 42. The clamping plate 42 is then released, and under the push of the clamping spring 43, the clamping plate 42 drives the contact plate 2 442 to approach the contact plate 1 441 on the partition plate 41, and the contact plate 1 441 and the contact plate 2 442 clamp the collection bag, and the arc grooves on the contact plate 1 441 and the contact plate 2 442 are opposite. The collection bag is limited and all the collection bags are placed in the storage box 1. After the collection bag is clamped and limited by the contact plate 1 441 and the contact plate 2 442, the storage cover 3 is aligned with the storage box 1, and then the storage cover 3 is directly pressed down to make the inclined surfaces of the engaging teeth 1 53 on the engaging block 52 and the engaging teeth 2 54 on the storage box 1 slide against each other, and at the same time, the engaging block 52 slides in the supporting block 51 and squeezes the engaging spring 55. When the storage cover 3 is completely covered on the storage box 1, under the push of the engaging spring 55, the engaging teeth 1 53 on the engaging block 52 and the engaging teeth 2 54 on the storage box 1 are clamped together, so that the storage cover 3 and the storage box 1 are fixed together, and the storage of the collection bag filled with gas is completed.
