[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This invention provides a continuous pressurization device. Through the cooperation of the continuous pressurization component and the connecting component, it can provide continuous gas pressure for a long time without power. Even if the gas intake is interrupted, it can still ensure continuous pressurization. It is easy to use, low in cost, and improves the chromatography efficiency of the chromatography column.

[0027] Figures 1-3 The diagram shown is an overall structural schematic of an embodiment of the continuous pressurization device of this utility model. Please refer to [link / reference]. Figures 1-3 The main structure of this embodiment includes: a continuous pressurization component and a connection component.

[0028] The continuous pressurization component is used for pressurization without power. Specifically, the continuous pressurization component includes an airbag 11, an air outlet 12 connected to the bottom surface of the airbag 11, an air inlet 13 connected to the side of the airbag 11, and a test instrument tube 14 located below the airbag 11.

[0029] In actual use, the user blows air into the air inlet 13 to inflate the airbag 11. The gas inside the airbag 11 is then discharged through the air outlet 12. Since the airbag 11 acts as a transfer point, even if there is a brief interruption in air intake at the air inlet 13, the airbag 11 can still ensure continuous pressurization of the tube 14 of the instrument to be tested, thus avoiding the interruption of pressurization.

[0030] The connecting assembly is used to facilitate inflation and pressurization. Specifically, the connecting assembly includes a round tube 21 located below the air outlet 12, a threaded tube 22 communicating with the round tube 21, a first groove 23 formed on the outer wall of the round tube 21, a connecting tube 24 located below the threaded tube 22, a first internal thread 25 formed in the connecting tube 24, an annular baffle 26 fixed to the outer wall of the connecting tube 24, a conical connector 27 communicating with the connecting tube 24, an air inlet tube 28 located at the air inlet 13, a valve 29 connected to the air inlet tube 28, and a second groove 210 formed on the outer wall of the air inlet tube 28.

[0031] In practical use, the air outlet 12 and the round tube 21 are fitted together, and the outer side of the air outlet 12 is bound in the first groove 23 by a rubber ring. The air inlet 13 and the air inlet tube 28 are fitted together, and the outer side of the air inlet 13 is bound in the second groove 210 by a rubber ring. Then, the user inserts the conical connector 27 into the tube 14 of the instrument to be tested. The user blows air through the air inlet tube 28 or other pressurizing devices to ventilate. The gas enters the air bag 11 for storage, and then the gas is injected into the tube 14 of the instrument to be tested through the conical connector 27. The valve 29 is used to control the opening and closing of the air inlet tube 28. The conical connector 27 is adapted to use tubes 14 of the instrument to be tested with different diameters.

[0032] Furthermore, it also includes a locking assembly, which includes a threaded frame 31 fixed to the bottom surface of the annular baffle 26 and an annular frame 32 disposed below the threaded frame 31; the locking assembly also includes a second internal thread 33 opened in the annular frame 32 and a threaded hole 34 opened on the outer wall of the annular frame 32.

[0033] In practical use, the threaded frame 31 is connected to the annular frame 32. When the tapered connector 27 is mated, the annular frame 32 covers the outside of the instrument tube 14 to be tested. Then, the user uses a threaded rod to pass through the threaded hole 34 until the end of the threaded rod abuts against the instrument tube 14 to be tested. This will lock the tapered connector 27 in a secondary position and prevent it from falling off.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
