Detailed Description

The following describes the embodiments of the present invention with reference to the drawings and examples.

As shown in fig. 1 to 3, a mobile phase jar sampling device comprising: the bottle body 1 and the bottle cap 2 which is connected with the top of the bottle body 1 in a threaded manner, and the bottle cap 2 can be opened to facilitate filling of mobile phase into the bottle body 1; the top of the bottle cap 2 is provided with a sampling hole 9, the top of the bottle cap 2 is provided with a fixed cylinder 3 corresponding to the sampling hole 9, the inside of the sampling hole 9 is provided with a straw 4 the bottom end of which extends to the bottom of the bottle body 1, the upper end of the straw 4 is provided with an elastic balloon 5 communicated with the straw 4, the elastic balloon 5 and the straw 4 form the same structure as a rubber head dropper, the extrusion balloon 5 can absorb the mobile phase in the bottle body 1 through the straw 4, the straw 4 is provided with a fixed plate 7 in threaded connection with the fixed cylinder 3, the straw 4 is screwed, the straw 4 drives the fixed plate 7 to rotate relative to the fixed cylinder 3, the straw 4 which rotates forward and backward can separate or connect the fixed plate 7 and the fixed cylinder 3, after the fixed plate 7 and the fixed cylinder 3 are separated, the balloon 5 can be extruded to absorb the mobile phase, the rubber head dropper is prevented from being taken from a test tube rack, the, can seal the thief hole 9, avoid the inside mobile phase of bottle 1 to spill to, straw 4 corresponds with bottle 1 and is connected, has avoided different mobile phase straws 4 to use mixedly.

Further, in order to better seal the sampling hole 9, the fixing plate 7 and the suction pipe 4 are of an integral structure, an external thread structure is arranged on the outer side of the fixing plate 7, an internal thread structure matched with the external thread structure is arranged on the inner side of the fixing cylinder 3, and the fixing plate 7 and the suction pipe 4 are of an integral hard plastic structure; the cover is equipped with sealing plug 8 on the straw 4 of fixed plate 7 below, and sealing plug 8 is the rubber buffer, and its axial is provided with the pore that is used for the suit in the straw 4 outside, and the bottom and the thief hole 9 phase-match of sealing plug 8, and after fixed plate 7 was packed into in the fixed section of thick bamboo 3 completely, the thief hole 9 was sealed to sealing plug 8, improved the sealed tightness of thief hole 9.
