Abstract
The utility model relates to a safe measuring cylinder special for a laboratory. In the laboratory, a lab worker needs to frequently use a measuring cylinder to measure dangerous liquids in experiments, but the liquid measured by a conventional measuring cylinder flows along the wall of the measuring cylinder, and the liquid always flows out to do harm to lab workers. A measuring cylinder capable of safely measuring liquids is urgently essential for laboratories. The utility model adopts the following technical scheme that a liquid container is internally provided with multiple straight keeping ports positioned in one straight line and also comprises a measuring cylinder, a lower sealing port capable of rotating around a rotary base is arranged under the measuring cylinder, the lower sealing port is connected with a vertical opening-closing operating rod, and a bracelet is arranged at the upper end of the opening-closing operating rod. The safe measuring cylinder special for the laboratory has the following beneficial effects that the safe measuring cylinder is safe and convenient, lab workers have no need to contact liquid with hands, and the safe measuring cylinder can be used for measuring dangerous liquids.
Description
Technical field:
The present invention relates to a kind of graduated cylinder, relate in particular to the special-purpose safe graduated cylinder in laboratory.
Background technology:
Often need measure certain dangerous liquid when experiment is done in inside, laboratory, often need use graduated cylinder, still traditional graduated cylinder need paste wall when using and operate, and often flows out human body is damaged.A kind of graduated cylinder that can measure liquid safely is badly in need of in the laboratory.
Summary of the invention: the purpose of invention: convenient for a kind of safety is provided, without the special-purpose safe graduated cylinder in the laboratory of the direct contact liq of hand.
In order to reach as above purpose; The present invention takes following technical scheme: there are a plurality of straight mouths of guarantor that are positioned at straight line liquid filled container inside; Also comprise graduated cylinder; Said graduated cylinder below has can be around the lower sealing that changes the base rotation, and lower sealing also links to each other with vertical switching function lever, and there is bracelet the switching function lever upper end.
Further technical scheme of the present invention is: liquid filled container top and bottom at least has and protects straight mouthful, protects straight mouth and is shaped as the shape that can closely suit graduated cylinder one side.
Adopt the special-purpose safe graduated cylinder in laboratory of as above technical scheme, have following beneficial effect: safety, convenient, without the direct contact liq of hand, can be used for measuring dangerous liquid.
Description of drawings:
In order to further specify the present invention, further describe below in conjunction with accompanying drawing:
Fig. 1 is the supplementary structure synoptic diagram of invention;
Fig. 2 is a structural representation of the present invention;
Wherein: 1. liquid filled container; 2. protect straight mouthful; 3. bracelet; 4. graduated cylinder; 5. envelope is encircled; 6. lower sealing; 7. change base.
Embodiment:
Below in conjunction with Fig. 1 to Fig. 2 embodiments of the invention are described, embodiment is not construed as limiting the invention:
There are a plurality of straight mouths 2 of guarantor that are positioned at straight line liquid filled container 1 inside, also comprises graduated cylinder 4, and said graduated cylinder 4 belows have can be around the lower sealing 6 that changes base 7 rotations, and lower sealing 6 also links to each other with vertical switching function lever, and bracelet 3 is arranged on the switching function lever.
Further technical scheme of the present invention is: liquid filled container 1 top and bottom at least has and protects straight mouthful 2, protects straight mouthful 2 and is shaped as the shape that can closely suit graduated cylinder one side.
When using, it is inner that device shown in Figure 2 is put into device shown in Figure 1, and device shown in Figure 1 inside remains holding liquid, and bracelet 3 loosens at this moment.
Liquid is through on graduated cylinder 4 lower directions, and a plurality of guarantors guarantee vertical filling liquid for straight mouthful 2, and behind correct position, bracelet 3 tensions are measured completion with liquid, and envelope ring 5 guarantees that liquid does not leak outside.Propose, pour out and get final product.
Because that writes is non exhaustive, the embodiment of this patent does not receive the restriction of above examples of implementation, and similarly embodiment is also in the protection domain of the utility model.
Claims (2)
