Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to shown in Fig. 1 and 2, the quick detachable back shroud of a kind of chromatograph described in the utility model, including being provided close to
Limiting plate 2 is enclosed in the side plate tail portion one of chromatograph 1, further includes back shroud plate body 3；There are one through-holes 4 for tool among back shroud plate body 3；
There are one straight slots 5 for tool between the inner wall of through-hole 4 and the lateral wall of back shroud plate body 3；There are one mandrils 6 for flexible connection in straight slot 5；
There is block 1 on the bar wall of mandril 6；Straight slot 5 has block 28 close to one end bottom of through-hole 4；Bullet is arranged on mandril 6
Spring 9；9 both ends of spring are separately fixed on block 1 and block 28；Back shroud plate body 3 is located on 4 position of through-hole to being externally provided with
One connecting tube 10；Cover 11 there are one being threadedly coupled in connecting tube 10；Conehead direction there are one being fixedly connected in cover 11
The nose cone 12 of through-hole 4；There is the card slot 13 being adapted to mandril 6 on the side plate tail portion inner wall of chromatograph 1.
Shown in Figure 4, there are one balls 17 close to the flexible connection of one end end of through-hole 4 for mandril 6.Setting one can be with
In the ball 17 that 6 end of mandril arbitrarily rolls, so as to so that nose cone 12 with cover 11 rotate inwardly get into when,
Ball 17 can be rolled along the conical surface of nose cone 12, so as to reduce the resistance between 12 conical surface of mandril 6 and nose cone, so as to
So that nose cone 12 is easier top pressure mandril 6.
Shown in Figure 2,3 medial surface of back shroud plate body is equipped with a circle gasket 14 with 2 corresponding position of limiting plate.If
The purpose for putting gasket 14 is raising back shroud plate body 3 and the air-tightness of 2 junction of limiting plate, and chromatography is remained in so as to reduce
Pernicious gas in instrument 1 is escaped from back shroud plate body 3 and 2 junction of limiting plate.
Shown in Figure 3, the outside of nose cone is removably connected with an identical pullover of shape 15.Since this practicality is new
After type is installed on chromatograph 1, nose cone 12 is constantly in 1 inside of chromatograph, since chromatograph 1 is after detection, no
Evitable that some harmful or corrosive substances can be retained inside chromatograph 1,12 extended stationary periods of nose cone are in chromatograph 1
Interior, surface may adhere to some coagulums or its surface being corroded property substance corrosion, so as to make the surface of nose cone 12
Uneven, such rough 12 surface of nose cone can increase the resistance between mandril 6, so as to be difficult to push up mandril 6
It rises.So one pullover 15 is set on the surface of nose cone 12, nose cone 12 to be replaced to be corroded, as long as periodic replacement pullover 15
, without replacing entire cover 11 and nose cone 12.
Shown in Figure 3, pullover 15 is connected to by bolt 16 in cover 11 far from conehead one end.Pass through 16 mode of bolt
Connection is convenient for removing or replacing pullover 15.
The installation process of back shroud is：By being pressed on one side on limiting plate 2 with sealing ring of back shroud plate body 3, then will lid
Body 11 is screwed into connecting tube 10, continues to rotate cover 11, so as to which cover 11 can together be moved inward with nose cone 12, due to circle
The face of conehead 12 is taper, so nose cone 12 when constantly moving inward, can constantly squeeze mandril 6, so as to make top
The constantly ejection outward of bar 6, until by the outer end crown of mandril 6 into the cover 11 that stops operating in card slot 13, so as to which mandril 6 passes through
Entire back shroud plate body 3 is stuck in the tail portion of chromatograph 1 by card slot 13.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
