Description
Technical field
The utility model relates to chromatograph maintenance technology field, specifically a kind of dimension for dismounting chromatograph seal nipple
Nurse's tool.
Background technique
There is a kind of common part sealing structure on the market at present, structure is made of seal nipple and deforming seal.
Seal nipple: one end is screw thread, and inside is the circular hole chamber with taper or circular arc, and there is a diameter in the other side
It is bigger than part, but the hole for being less than deforming seal diameter is run through.
Deforming seal: the cylinder with taper or circular arc and intermediate porose structure.Outer dia is greater than seal nipple
The diameter of hollow chamber's diameter, interstitial hole is suitable with diameter of part.
Sealing principle: after part is inserted into seal nipple first, then by deforming seal being inserted in part end, later will set
Enter end part to retreat in seal nipple, be rotated by connector, is squeezed and deformed to reach by deforming seal using connector rotation
To sealing effect.After the sealing structure, since deforming seal deformation is serious, deforming seal medial small hole connects with sealing
Head aperture difference very little, general purpose tool are difficult to touch deformed deforming seal, and in maintenance, replacement, deforming seal is past
It is past to be difficult to take out.
Utility model content
Insufficient for the above-mentioned prior art, the utility model provides a kind of maintenance tool for dismounting chromatograph seal nipple.
A kind of maintenance tool dismounting chromatograph seal nipple provided by the utility model is real by the following technical programs
Existing:
A kind of maintenance tool dismounting chromatograph seal nipple, it is characterised in that: including mandril, connector, connecting rod, length
Bar, described connector one end are fixedly installed mandril, and connector other end middle position offers blind hole, the blind hole bottom
Portion is fixedly installed iron plate, and described connecting rod one end is fixed on the middle part of stock, and the other end is provided with magnet, the connecting rod
Go deep into blind hole and magnet can be adsorbed with iron plate, the connecting rod outer wall is arranged with multiple rubber rings.
The outer diameter of the rubber ring is equal to the aperture of blind hole.
The mandril and connector are integrally formed, and are assumed a " convex " shape.
The beneficial effects of the utility model are:
1, what this tool can be convenient ejects deforming seal；
2, the diameter of mandril can be customized according to the specification of seal nipple, and connecting rod can be adapted to stock it is a variety of
Connector；
3, stock can eject convenient for holding and having an effect conducive to by deforming seal.

Fig. 2 is structural schematic diagram at A in Fig. 1；
Fig. 3 is schematic diagram when the utility model is used；
Fig. 4 is seal nipple, deforming seal and part mounting structure schematic diagram.
Marked in the figure: mandril 1, connector 2, connecting rod 3, stock 4, iron plate 5, magnet 6, rubber ring 7, seal nipple 8, change
Shape sealing element 9 and part 10.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of maintenance tool of dismounting chromatograph seal nipple as depicted in figs. 1 and 2, including mandril 1, connector 2, company
Extension bar 3, stock 4, described 2 one end of connector are fixedly installed mandril 1, and 2 other end middle position of connector offers blind
Hole, the blind via bottom are fixedly installed iron plate 5, and described 3 one end is fixed on the middle part of stock 4, and the other end is provided with magnet
6, the connecting rod 3 gos deep into blind hole and magnet 6 can be adsorbed with iron plate 5, and 3 outer wall of connecting rod is arranged with multiple rubber rings
7, the outer diameter of the rubber ring 7 is equal to the aperture of blind hole, and the mandril 1 is integrally formed with connector 2, assumes a " convex " shape.
As shown in Figure 3 and Figure 4, when in use, connecting rod 3 is goed deep into blind hole, magnet 6 is adsorbed with iron plate 5.
Rubber ring 7 can increase stability, prevent connecting rod 3 from shaking in blind hole.Firmly by part 10 from seal nipple 8 and deformable seal
It extracts, mandril 1 is inserted into the lesser hole of 8 one end of seal nipple in part 9, hold stock 4 and exert oneself a top, can to deform close
Sealing 9 is ejected from 8 other end of seal nipple.
Embodiment described above only indicates the embodiments of the present invention, and the description thereof is more specific and detailed, but not
It can be interpreted as the limitation to the scope of the utility model.It should be pointed out that for those of ordinary skill in the art, not
Under the premise of being detached from the utility model design, various modifications and improvements can be made, these belong to the utility model protection
Range.
