Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: the utility model provides a burette nipple convenient to use, including first glass pipe 1, rubber cap 5, connector 6, slider 10, stopper 12 and second glass pipe 14, the surface cover of first glass pipe 1 is equipped with rubber sleeve 2, and the both sides of rubber sleeve 2 articulate there is mount 3, the inside of mount 3 is inserted and is equipped with built-in frame 4, the through-hole has been seted up in the intermediate position department of rubber sleeve 2, and through-hole diameter length is unanimous with first glass pipe 1 and second glass pipe 14 cross section length, it sets up to "L" shape to state built-in frame 4, the top surface of built-in frame 4 is provided with the external screw thread, the inner wall of mount 3 is provided with the internal thread that mutually supports with the external screw thread, under articulated effect, expand rubber sleeve 2 both sides mount 3 and be a style of calligraphy, according to the length of bottleneck, turn on clockwise rotation and unscrew the regulation to suitable length in built-in frame 4 from mount 3, the user slides rubber sleeve 2 to suitable position on first glass pipe 1 and second glass pipe 14 The whole device is vertically inserted into a bottle, meanwhile, the built-in frames 4 in L shapes on two sides are erected on the bottle opening, the thumb and the forefinger are used for squeezing the rubber cap 5 to control the suction or dropping amount of the reagent, the use of a user is facilitated, the phenomenon that the second glass tube 14 extends into the bottle opening or the phenomenon that the dropper nipple cannot be kept vertical due to shaking of hands during reagent dropping is reduced.

The bottom through pipe connector 6 of the rubber cap 5 is in threaded connection with the top of the first glass tube 1, the bottom of the rubber cap 5 is provided with a suction nozzle 7, the bottom of the suction nozzle 7 penetrates through the top of the first glass tube 1, the suction nozzle 7 is communicated with the first glass tube 1, the positions of two side walls of the first glass tube 1 below the suction nozzle 7 are respectively provided with a sliding chute 8, a sliding block 10 is embedded in the sliding chute 8, one end, far away from the sliding chute 8, of the sliding block 10 is welded with a cover plate 11, the bottom of the cover plate 11 is welded with a buoyancy ball 13, a plug 12 is pressed in the middle position of the top of the cover plate 11, the suction nozzle 7 is in an inverted funnel shape, the suction nozzle 7 is arranged in a circular through pipe, when the suction force is too large due to the pinching force of a user, the sliding chute 8 and the sliding block 10 are used in a matched mode, when the liquid is too much and meets the buoyancy ball 13, thereby effectively preventing the liquid from entering the rubber cap 5 to cause the corrosion in the rubber cap 5.

The inside second glass pipe 14 that is equipped with of inserting of first glass pipe 1 below apron 11, the surface of first glass pipe 1 and second glass pipe 14 all is provided with scale mark 9, the length of first glass pipe 1 and second glass pipe 14 is unanimous, position department below 1 inner wall bottom of first glass pipe and buoyancy ball 13 all is provided with the internal thread, 14 top surfaces of second glass pipe all are provided with the external screw thread of mutually supporting with the internal thread, use through scale mark 9, make the steerable volume of inhaling of user, and pass through threaded connection, the length of cooperation first glass pipe 1 and second glass pipe 14 is unanimous, convenient to use person adjusts and deposits.

The working principle is as follows: before use, a user holds the second glass tube 14 by hand, rotates clockwise, unscrews the second glass tube 14 from the upper end in the first glass tube 1 under the action of threaded connection, slides to the lower end of the first glass tube 1 vertically in a sliding manner, screws counterclockwise, then unfolds the fixing frames 3 on the two sides of the rubber sleeve 2 into a straight shape under the action of hinging, rotates the built-in frame 4 clockwise from the fixing frames 3 according to the length of a bottle mouth and unscrews to adjust to a proper length, and then, after the user slides the rubber sleeve 2 to a proper position on the first glass tube 1 and the second glass tube 14 by hand, the whole device is vertically inserted into the bottle, meanwhile, the built-in frames 4 with L-shaped two sides are erected on the bottle mouth, and then the thumb and the forefinger press the rubber cap 5 to control the suction or dripping amount of a reagent, so that one-time operation can be completed;

if in the use, the user leads to the suction when too big because of holding between the fingers power, use through the cooperation of spout 8 and slider 10, it is too much when liquid, buoyancy ball 13 is met to liquid, buoyancy ball 13 rises and drives apron 11 and stopper 12 along with spout 8 is ascending perpendicularly, make stopper 12 plug up suction nozzle 7, thereby the effectual condition that has prevented that liquid from getting into rubber cap 5 and leading to the internal corrosion of rubber cap 5, wait to use the back that finishes, like this operation, with rubber sleeve 2 and mount 3 and built-in shelf 4 after playback, under rethread threaded connection's the effect, respectively unscrew rubber cap 5 and second glass pipe 14 rotation, take off from first glass pipe 1, it can to take appointed position department to wash and deposit.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
