Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 3 of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

As shown in fig. 1-3: a burette placing device comprises a barrel body 1 and a fixing block 2 arranged on the side edge of the barrel body 1, wherein a storage groove 3 is arranged in the fixing block 2, a burette 4 is placed in the storage groove 3, a clamping ring 5 is arranged on the fixing block 2 corresponding to the burette 4, a positioning ring 6 is arranged on the burette 4 corresponding to the clamping ring 5, a limiting mechanism is arranged on the clamping ring 5 corresponding to the positioning ring 6, the limiting mechanism comprises a positioning block 7 arranged on the clamping ring 5, a limiting hole 8 is arranged on the positioning block 7, an elastic tongue 9 is slidably arranged in the limiting hole 8, the end part of the elastic tongue 9 is arranged in a conical structure corresponding to the positioning ring 6, a baffle plate 10 is arranged at the other end of the elastic tongue 9, a first spring 11 is arranged on the elastic tongue 9, one end of the first spring 11 is connected with the baffle plate 10, the other end of the first spring 11 is connected with the positioning block 7, and a clamping mechanism is arranged in the fixing block 2 corresponding to the burette 4; the clamping mechanism can clamp the dropper 4, so that the end part of the dropper 4 cannot be scratched in the storage groove 3 and further damaged, and the positioning mechanism limits the positioning ring 6, so that the dropper 4 cannot fall off from the storage groove 3.

Specifically, a burette placer, the round hole that aligns on snap ring 5 after burette 4 used inserts, holding ring 6 on burette 4 can contact the inclined plane of bullet tongue 9 tip in the in-process that burette 4 inserts, thereby make holding ring 6 press the inclined plane of bullet tongue 9 tip make bullet tongue 9 tip retract spacing hole 8 in, thereby burette 4 just can continue to take holding ring 6 to move down, then first spring 11 will take baffle 10 just can reset, and then bullet tongue 9 just can reset in spacing hole 8, thereby bullet tongue 9 tip just can carry out spacing to holding ring 6, and then burette 4 just can not take out from storage tank 3 under the condition of not stirring baffle 10.

According to one embodiment of the present invention, as shown in figures 1-3,

the cross sections of the spring tongue 9 and the limiting hole 8 are both polygonal structures. Namely, the elastic tongue 9 can not rotate in the process of sliding back and forth in the limit hole 8, so that the inclined surface at the end part of the elastic tongue 9 can not rotate, and the end part of the elastic tongue 9 can normally limit the positioning ring 6.

According to another embodiment of the present invention, as shown in figures 1-2,

fixture includes a plurality of recesses 12 that correspond the setting of storage tank 3 in the fixed block 2, set up telescopic link 13 in the recess 12, telescopic link 13 tip sets up splint 14, second spring 15 is established to the cover on the

telescopic link

13, 15 one ends of second spring are connected with recess 12 tip, the 15 other ends of second spring are connected with splint 14. Because splint 14 sets up so that can make when burette 4 places to the storage tank 3 in the cistern 3 is inclined, the lateral wall of burette 4 can push away splint 14 and move to both sides, and after burette 4's rigidity, second spring 15 just can promote splint 14 and carry out the centre gripping to burette 4 to can make 4 body of burette 4 can not bump with the inside wall of storage tank 3 in storage tank 3 and scratch, thereby avoid burette 4's tip to cause the damage. And the arc-shaped structure of the clamping plate 14 is matched with the outer side wall of the dropper 4, so that the bottle body of the dropper 4 can be clamped more stably.

In another embodiment of the present invention, as shown in figures 1-2,

a rubber layer is arranged on the inner side of the clamping plate 14. The rubber layer can increase the friction force between the clamping plate 14 and the outer side wall of the dropper 4, so that the clamping plate 14 can clamp the dropper 4 more stably, and the outer side wall of the dropper 4 can be prevented from being damaged in the process of clamping the dropper 4 by the clamping plate 14.

set up connecting block 16 corresponding fixed block 2, set up water catch bowl 17 on the connecting block 16, the connecting block 16 tip outside sets up the screw thread, corresponds the screw thread sets up thread groove 18 at the 3 tip of strorage groove. The threads on the connecting block 16 are aligned with the thread grooves 18 and then are inserted in a rotating mode, so that the connecting block 16 can be connected with the fixing block 2, liquid dropping in the dropper 4 cannot drop on a worker, and water in the water collecting tank 17 can be treated by taking the connecting block 16 down from the bottom of the fixing block 2 at regular intervals.

The utility model discloses a theory of operation:

after the dropper 4 is used, the dropper 4 is aligned with the round hole in the clamping ring 5 and inserted, the side wall of the dropper 4 can push the clamping plate 14 to move towards two sides in the inserting process, after the dropper 4 is fixed in position, the second spring 15 can push the clamping plate 14 to clamp the dropper 4, meanwhile, the positioning ring 6 on the dropper 4 can contact with the inclined surface of the end part of the elastic tongue 9, the positioning ring 6 is enabled to press the inclined surface of the end part of the elastic tongue 9, so that the end part of the elastic tongue 9 retracts into the limiting hole 8, the dropper 4 can continue to drive the positioning ring 6 to move downwards, then the first spring 11 can drive the baffle plate 10 to reset, the elastic tongue 9 can reset in the limiting hole 8, the end part of the elastic tongue 9 can limit the positioning ring 6, and the dropper 4 cannot be taken out of the storage groove 3 under the condition that the baffle plate 10 is not pulled.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
