Description

Technical Field

[0001] The present application relates to the technical field of gas containers, and in particular to a gas sample holding container. Background Art

[0002] A gas sample holding container is a device used to collect, store and hold gas samples. It is commonly used in environmental monitoring, industrial process control, scientific research and other fields. These containers are usually designed as sealed structures to ensure the integrity and stability of the samples and prevent contamination or interference from external impurities.

[0003] At present, most gas sample holding containers only have the function of gas storage and collection. During the gas introduction process, the gas itself may be mixed with other solid particle impurities. The impurities enter the container with the gas and may react chemically with the gas, thereby contaminating and changing the properties of the gas, affecting the subsequent analysis and the accuracy and reliability of the experiment. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a gas sample holding container to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the utility model provides a gas sample holding container, comprising a container body, a protective frame fixedly installed on the outer surface of the container body, a gas valve arranged on the container body, a one-way valve fixedly connected to the top of the container body, a connecting chamber fixedly connected to the top of the one-way valve, a filter screen detachably installed inside the connecting chamber, a sealing cover detachably installed on the top of the connecting chamber, a gas injection pipe valve arranged on the top of the sealing cover, a sealing limit ring fixedly connected to the bottom of the sealing cover, and a locking mechanism arranged on the outer surface of the connecting chamber.

[0006] Preferably, the locking mechanism includes a fixing frame fixedly connected to the outer surface of the connecting chamber, and a rotating shaft is fixedly penetrated through the inner side of the fixing frame. The locking mechanism can enable the hook to quickly and stably clamp the sealing limit ring, thereby allowing the sealing cover to be stably installed on the top of the connecting chamber.

[0007] Preferably, the outer surface of the rotating shaft is rotatably connected to a deflection table, an outer spring is provided on the inner side of the fixed frame, one end of the outer spring is fixedly connected to the outer surface of the deflection table, and the outer spring is inclined so that the deflection table can rotate along the rotating shaft under its pulling.

[0008] Preferably, a slide plate is slidably connected to the inner surface of the deflection table, and a shift rod is fixedly provided on the inner side of the slide plate.

[0009] Preferably, an inner spring is provided on the movable sleeve on the outer surface of the shift rod, and a hook is provided on the top of the shift rod. The hooks are designed in three groups, and the evenly spaced parts are on the outer periphery of the sealing limit ring, which is consistent with the number of related components such as the deflection table.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The gas sample holding container and the connecting chamber are provided with a detachable filter disc, which can effectively filter the solid particle impurities mixed in the gas to prevent them from entering the container and reacting chemically with the gas, so as to maintain the purity of the gas, avoid pollution and change of the properties of the gas, thereby ensuring the accuracy and reliability of subsequent analysis and experiments.

[0012] 2. The gas sample holding container can quickly disassemble and assemble the cover through the locking mechanism, so as to clean and replace the filter disc in the connecting chamber, and clean the impurities filtered out from the filter disc, thereby ensuring the normal operation and maintenance of the gas sample holding container.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-4A gas sample holding container comprises a container body 1, a protective frame 2 is fixedly installed on the outer surface of the container body 1, a gas valve 3 is arranged on the container body 1, a one-way valve 4 is fixedly connected to the top of the container body 1, a connecting chamber 5 is fixedly connected to the top of the one-way valve 4, a filter screen plate 6 is detachably installed inside the connecting chamber 5, a sealing cover 7 is detachably installed on the top of the connecting chamber 5, a gas injection pipe valve 8 is arranged on the top of the sealing cover 7, a sealing limit ring 9 is fixedly connected to the bottom of the sealing cover 7, and a locking mechanism is arranged on the outer surface of the connecting chamber 5.

[0020] Through the above technical scheme, when the device is in use, gas can be injected into the connecting chamber 5 through the gas injection pipe valve 8, and solid particle impurities in the airflow can be filtered through the filter mesh plate 6. Finally, the filtered airflow can enter the container body 1 through the one-way valve 4 for collection and storage.

[0021] Specifically, the locking mechanism includes a fixing frame 10 fixedly connected to the outer surface of the communicating chamber 5 , and a rotating shaft 11 is fixedly penetrated through the inner side of the fixing frame 10 .

[0022] Through the above technical solution, when the deflection platform 12 rotates along the rotating shaft 11 under the action of the external spring 13 , the hook 17 will gradually approach the sealing limit ring 9 .

[0023] Specifically, the outer surface of the rotating shaft 11 is rotatably connected to the deflection table 12 , and an outer spring 13 is disposed inside the fixing frame 10 . One end of the outer spring 13 is fixedly connected to the outer surface of the deflection table 12 .

[0024] Through the above technical solution, the two groups of inclined outer springs 13 can effectively pull the deflection table 12 so that the upper end of the deflection table 12 is close to the cover 7.

[0025] Specifically, a slide plate 14 is slidably connected to the inner surface of the deflection platform 12 , and a shift rod 15 is fixedly provided on the inner side of the slide plate 14 .

[0026] Through the above technical solution, when the inner spring 16 elastically pulls the slide plate 14 , the shift rod 15 can be synchronously driven by the slide plate 14 .

[0027] Specifically, an inner spring 16 is movably sleeved on the outer surface of the shift rod 15 , and a hook 17 is disposed on the top of the shift rod 15 .

[0028] Through the above technical solution, the hook 17 can be relatively firmly clamped on the edge of the sealing limit ring 9 under the indirect action of the inner spring 16.

[0029] Working principle: During use of the device, the cover 7 can be stably installed on the connecting chamber 5 through the locking mechanism, and the filter plate 6 can be easily cleaned and replaced. When installing the cover 7, it needs to be locked on the top of the connecting chamber 5. Under the pulling force of the outer spring 13, the deflection table 12 will rotate along the rotating shaft 11, and the upper end of the deflection table 12 will gradually approach the cover 7. At the same time, under the pulling of the inner spring 16 on the slide plate 14, the slide plate 14 will move down along the inside of the deflection table 12, and then drive the hook 17 to move down synchronously through the shift rod 15, until the hook 17 is tightly clamped by the pulling force of the outer spring 13 and the inner spring 16. The edge of the sealing limit ring 9 makes it stably and tightly stuck on the top of the connecting chamber 5. When removing the sealing cover 7, you only need to pull up the hook 17 and push it outward to separate it from the sealing limit ring 9. When gas is introduced into the connecting chamber 5 through the air injection pipe valve 8, the airflow will pass through the filter mesh plate 6 to filter out the mixed solid particle impurities, and the filtered airflow will be input into the container body 1 through the one-way valve 4 for collection and storage. The gas in the container body 1 can be discharged through the air valve 3. The protective frame 2 designed outside the container body 1 is to reduce the impact of the external environment on the device and reduce the damage to the device caused by external collision.

[0030] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
