Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a sterile sampling bag rack with good sealing effect. Background Technique

[0002] A sampling bag is a gas soft packaging bag made of composite film for containing sample gas. The material used has strong corrosion resistance, extremely low air permeability, and poor adsorption. It can directly supply sample gas from the bag or sample with a syringe. A valve and a sampling pad are installed on the bag. The stable storage period of the sample gas contained is 1 - 3 months. Replacing small steel cylinders with this soft packaging bag for sampling has the advantages of being light, cheap, and portable. A multi-compartment sterile sampling bag rack is a rack for storing sterile sampling bags. At present, the application of multi-compartment sterile sampling bag racks in the market has been very extensive. A sterile sampling bag is a safe and pollution-free sampling container, and the sampling bag rack is convenient for storing sterile sampling bags. However, most of the structures of multi-compartment sterile sampling bag racks are simple. Most of the existing multi-compartment sterile sampling bag racks are just a framework, and the separate framework has no sealing mechanism, so that the sterile sampling bag cannot be sealed and placed, resulting in changes in the samples inside the sterile sampling bag due to the influence of air.

[0003] After retrieval, the patent with the Chinese patent application number 202220258480.1 discloses a multi-compartment sterile sampling bag rack with good sealing effect, including a sampling bag rack body. An aseptic sampling bag body is movably installed inside the sampling bag rack body. A sealing mechanism is fixedly installed outside the sampling bag rack body, and four supporting legs are fixedly installed at the bottom of the sealing mechanism. The following deficiencies exist in the multi-compartment sterile sampling bag rack with good sealing effect in the above-mentioned literature: all sampling bags are located in the same sealing mechanism, and when a certain sampling bag needs to be taken out, it will affect the overall sealing performance.

[0019] 6. Through the above solution, the clamping mechanism is fixed inside the end cap, so that the clamped sampling bag is kept in a vertical state, avoiding the situation that when the sample is less, the sampling bag is directly placed at the bottom of the sealed box. Without support, the sampling bag will be folded and stacked, which is not conducive to observing the internal sample. At the same time, the clamping mechanism is fixed inside the end cap, and when the end cap is removed, the sampling bag can be taken out together, improving the convenience.

[0020] 7. Through the above solution, the spring provides sufficient pressure to clamp the sampling bag. The setting of the pressure roller facilitates the operator to horizontally insert the seal at the upper part of the sampling bag between the two pressure rollers along the rotation direction of the pressure roller. During the installation, the seal is further pressed tightly to ensure the sealing performance of the sampling bag and provide an additional guarantee for the sample.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] Example 1

[0031] A sterile sampling bag holder with good sealing effect, such as Figures 1-5 As shown, it includes a sealed box 1, an end cover 2 is installed on the sealed box 1, a clamping mechanism is installed inside the end cover 2, and a sampling bag 17 is clamped on the clamping mechanism. A plurality of slide grooves 6 are arranged on the right side wall of the sealed box 1, and a spring piece 7 is respectively installed on the inner wall of the plurality of slide grooves 6. A plurality of sliders 5 are provided on the left side wall of the sealed box 1 corresponding to the plurality of slide grooves 6, and a spring piece 7 is respectively installed on the lower surface of the plurality of sliders 5. A plurality of sealed boxes 1 are combined and connected through the plurality of slide grooves 6 and the sliders 5.

[0032] Through the described solution, each sealed box is an independent space for storing a sampling bag. When a sampling bag needs to be taken out, it will not affect the sealing of other sealed boxes. Multiple sealed boxes can be combined into a whole through a slide block, which is convenient for movement and transportation, and the spring sheet plays a fixing role.

[0033] The device is further configured such that a handle 4 is installed on the front of the sealing box 1 .

[0034] The installation of the handle makes it easy for the operator to remove or install the combined sealing box.

[0035] The device is further configured such that an observation window 3 is provided on the front side of the sealing box 1 and the observation window 3 is made of a transparent material.

[0036] Through the solution, the operator can easily see the status of the sample in the sealed box without opening the end cover to check.

[0037] The device is further configured such that a first connecting block 8 is provided on the front side of the end cover 2, a second connecting block 9 is provided on the rear side of the end cover 2, and a first connecting groove 10 and a second connecting groove 11 are provided at corresponding locations on the upper end of the sealing box 1.

[0038] According to the solution, the end cover and the sealing box are effectively connected through the front and rear first connecting blocks and the second connecting blocks, thereby ensuring the sealing performance of the device.

[0039] The device is further configured such that a sealing strip 18 is installed below the end cover 2 , and a corresponding sealing groove 19 is opened above the sealing box 1 .

[0040] Through the above solution, when the end cover is installed on the sealed box, the sealing strip is pressed into the sealing groove, which fully improves the sealing performance of the device and prevents air from flowing in through the gaps.

The output end of the telescopic rod 14 is rotatably installed with a pressure roller 16 through a pressure roller bracket 15. A spring 13 is arranged on the outer wall of the telescopic rod 14. The two ends of the spring 13 are respectively connected to the bracket 12 and the pressure roller bracket 15.

[0044] Through the above solution, the spring provides sufficient pressure to clamp the sampled bag. The pressure roller is provided to facilitate the operator to horizontally insert the seal of the upper part of the sampled bag between the two pressure rollers along the rotation direction of the pressure roller. During installation, the seal is further pressed tightly, ensuring the sealing performance of the sampled bag and providing an additional guarantee for the sample.

[0045] Working principle: Open the end cover 2, and horizontally insert the seal of the upper part of the sampled bag 17 after collecting the sample between the two pressure rollers 16 along the rotation direction of the pressure roller 16. During installation, the seal is further pressed tightly. The two pressure rollers 16 mutually squeeze and clamp the sampled bag 17 under the action of the spring 13; Subsequently, the end cover 2 is installed on the sealed box 1 through the first connection block 8, the second connection block 9, and the corresponding first connection groove 10 and second connection groove 11; Subsequently, as needed, a plurality of the sealed boxes 1 are connected and combined through a plurality of the sliders 5 and chutes 6 on both sides.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
