Description

Technical Field

[0001] The utility model relates to the technical field of gas phase mass spectrometers, in particular to a high-efficiency sealing gasket disassembly tool. Background Art

[0002] Gas chromatography-mass spectrometry is a common device for organic matter detection. The chromatographic column in the gas chromatograph is inserted into the transmission line, and the chromatographic column is introduced into the ion source of the mass spectrometer through the transmission line to achieve combined analysis. The transmission line is the key device that connects the gas chromatograph and mass spectrometer together.

[0003] Since the mass spectrometer is in a high vacuum state, the transmission line needs to be sealed. A graphite gasket is installed between the transmission line and the chromatographic column to ensure its sealing. The graphite gasket is pressed between the transmission line and the chromatographic column by a special nut for the transmission line, but the graphite gasket after use will be tightly embedded in the special nut for the transmission line and is difficult to remove.

[0004] Generally, the method used to remove the graphite gasket that has been embedded in the special nut for the transmission line is to poke it out with an awl, or to use a hammer and an awl to remove the graphite gasket. Because the graphite gasket is embedded too tightly, it is generally laborious and troublesome to hammer and chisel it, and it is also necessary to find suitable tools. The strength of the hammer and chisel also needs to be controlled well, and it requires the cooperation of both hands, which is easy to hurt the hands. Such operations will not only affect the efficiency of work, but also cause damage to the graphite gasket or the special nut for the transmission line. Utility Model Content

[0029] 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.

[0030] like Figure 1 As shown, it is a stereoscopic diagram of a sealing gasket removal tool according to an embodiment of the utility model. The utility model provides an efficient sealing gasket removal tool, which consists of a pressure rod 1, a connecting rod 2, a base 3, a spring 4, a sliding rod 5, a pressure needle 6, a nut seat 7, a top screw 8, a pin shaft 1 9, a pin shaft 2 10, and a pin shaft 3 11, and is mainly used to remove a graphite sealing gasket 13 from a special nut 12 for a transmission line.

[0031] The rear end of the pressure rod 1 is a gripping end, and the front end is pivotally connected to the upper end of the connecting rod 2 through a pin 1 9, so that the connecting rod 2 can rotate around the pin 1 9, and the lower end of the connecting rod 2 is pivotally connected to the front end of the base 3 through a pin 2 10. The rear end of the base 3 is a hand-held end, and the hand-held end of the base 3 is arranged opposite to the gripping end of the pressure rod 1;

[0032] The upper end of the slide bar 5 is mounted on the pressure bar 1 by the pin shaft 3 11, so that the slide bar 5 can rotate around the pin shaft 3 11, and the lower end of the slide bar 5 is inserted into the spring 4 and then extends into the slide groove arranged vertically on the base 3, so that the slide bar 5 can move up and down in the slide groove, and the vertical characteristics of the movement are ensured to prevent the positioning from being inaccurate or the angle of inclination when pressing the graphite sealing gasket 13, resulting in jamming;

[0033] A threaded hole is provided at the lower end of the slide rod 5, and a pressure needle 6 is connected to the lower end of the slide rod 5 by a thread. A needle-shaped structure is provided at the lower end surface of the pressure needle 6 for pressing out the graphite sealing gasket 13; wherein the preferred size range of the needle-shaped structure is: a diameter between 0.5-2mm, and a length between 2mm-20mm; and different types of pressure needles 6 can be replaced according to different types of transmission line special nuts 12;

[0034] like Figure 2 , Figure 3As shown, the base 3 also extends downward and forward to form a base, and a circular hole is provided on the base corresponding to the bottom of the slide slot, a nut seat 7 is installed above the circular hole, and the nut seat 7 is tightened along the side of the circular hole by a top screw;

[0035] like Figure 2 , Figure 3 As shown, the transmission line dedicated nut 12 is placed in the nut seat 7, and one end of the graphite sealing gasket 13 is arranged upward; specifically, the lower end of the transmission line dedicated nut 12 is a threaded hole, and the upper end is a tapered hole. The graphite sealing gasket 13 is embedded in one end of the tapered hole inside the transmission line dedicated nut 12. The graphite sealing gasket 13 has two structures, one is a tapered structure without a through hole, and the other is a tapered structure with a through hole in the center for passing through the chromatographic column and sealing, and the through hole is generally less than 0.5mm in diameter.

[0036] When in use, pinch the holding end of the pressure rod 1 and the hand-held end of the base 3 by hand, the spring 4 is compressed, the slide bar 5 moves downward, driving the pressure needle 6 to move downward, and the pressure needle 6 is inserted into one end of the tapered hole of the special nut 12 for the transmission line. The pressure needle 6 presses the graphite sealing gasket 13. Since the diameter of the pressure needle 6 is larger than the diameter of the middle through hole of the graphite sealing gasket 13, the pressure is all applied to the end face of the graphite sealing gasket 13, pressing and separating the graphite sealing gasket 13 from the inside of the tapered hole of the special nut 12 for the transmission line; when the hand is released, due to the tension of the spring 4, the pressure rod 1 drives the slide bar 5 and the pressure needle 6 to move upward. At this time, the graphite sealing gasket 13 can be conveniently removed from the special nut 12 for the transmission line by hand.
