Abstract
The utility model relates to a student learning field especially relates to safe beaker is used in experiment. Contain the first half and the latter half, the first half contains the bellied inner wall that stretches out down, and the cross -section of stretching out the inner wall contains the screw thread for triangle -shaped and edge, and the latter half contains the indent part, and the cross -section of indent part contains the screw thread for triangle -shaped and edge, stretches out screw thread that the inner wall energy of rotation contains through the edge entering the latter half of screwing. Beneficial effect: when A. Needing the large capacity, stretch out screw thread that the inner wall energy of rotation contains through the edge entering the latter half of screwing, can the expansion capacity, the B. Triangle -shaped edge contains the screw thread, is exactly an enclosed construction of falling after rising after consequently sealing, and the leak protection effect is better, C. In the time of abluent, unpack the first half and the latter half apart, wash respectively, avoid the beaker to be difficult to excessively deeply wash.
Description
Technical field
The utility model relates to Students ' Learning field, particularly relates to test and uses safe beaker.
Background technology
The defect of prior art is:
The materials such as sulfuric acid stick on cup outer wall and easily corrode hand;
Beaker capacity cannot adjust;
Too dark beaker is difficult to cleaning;
There is no a kind of method adding liquid from cup surrounding.
Utility model content
The object of utility model: in order to provide a kind of test of better effects if safe beaker, specific purposes are shown in multiple substantial technological effects of concrete implementation section.
In order to reach as above object, the utility model takes following technical scheme:
Safe beaker is used in test, it is characterized in that, comprise the first half and the latter half, described the first half comprises stretches out inwall towards lower convexity, the cross section of stretching out inwall is triangle and limit comprises screw thread, the latter half comprises female parts, and the cross section of female parts is triangle and limit comprises screw thread, stretches out inwall and rotates to screw by the screw thread that limit comprises and enter the latter half.
The further technical scheme of the utility model is, described the latter half comprises outer raised portion, described outer raised portion comprises screw thread, also comprise stop portions, described stop portions comprises the curved wall portion of connecting wall part and connecting wall upper, the inwall of described connecting wall part comprises screw thread and connecting wall part energy screw thread is screwed onto on outer raised portion.
The further technical scheme of the utility model is, the edge of described curved wall portion comprises targeting port.
The further technical scheme of the utility model is, the arch section of described curved wall portion comprises a circle groove.
Adopt the utility model of as above technical scheme, have following beneficial effect relative to prior art: time A. needs jumbo, stretch out inwall and rotate to screw by the screw thread that limit comprises and enter the latter half, can capacity be expanded; B. triangle edges comprises screw thread, be exactly an enclosed construction of falling after rising after therefore closing, leak preventing effect is better; When C. cleaning, take the first half and the latter half apart, clean respectively, avoid beaker to be excessively deeply difficult to cleaning.
Accompanying drawing explanation
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
Fig. 1 is utility model structural representation;
Fig. 2 is the structural representation of coupling part;
Fig. 3 is jacket structure schematic diagram;
Wherein: 1. the first half; 2. stretch out inwall; 3. the latter half; 4. female parts; 5. outer raised portion; 6. curved wall portion; 7. connecting wall part; 8. targeting port.
Detailed description of the invention
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
Safe beaker is used in test, it is characterized in that, comprise the first half and the latter half, described the first half comprises stretches out inwall towards lower convexity, the cross section of stretching out inwall is triangle and limit comprises screw thread, the latter half comprises female parts, and the cross section of female parts is triangle and limit comprises screw thread, stretches out inwall and rotates to screw by the screw thread that limit comprises and enter the latter half.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are for one of any as follows: time A. needs jumbo, stretch out inwall and rotate to screw by the screw thread that limit comprises and enter the latter half, can expand capacity; B. triangle edges comprises screw thread, be exactly an enclosed construction of falling after rising after therefore closing, leak preventing effect is better; When C. cleaning, take the first half and the latter half apart, clean respectively, avoid beaker to be excessively deeply difficult to cleaning.
Triangle edges comprises on face that screw thread refers to triangle edges place and comprise screw thread.
Described the latter half comprises outer raised portion 5, described outer raised portion comprises screw thread, also comprise stop portions, described stop portions comprises the curved wall portion of connecting wall part and connecting wall upper, the inwall of described connecting wall part comprises screw thread and connecting wall part energy screw thread is screwed onto on outer raised portion.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows, composition graphs 2 and Fig. 3, and connecting wall part energy screw thread is screwed onto on outer raised portion, therefore when from top time of falling sulfuric acid, even if operate incorrect, cause sulfuric acid stream to get off, also can not corrode hand.
The further technical scheme of the utility model is, the edge of described curved wall portion comprises targeting port.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows, composition graphs 2, directly the liquid of curved wall portion can be derived.
The arch section of described curved wall portion comprises a circle groove.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows, and be screwed onto on outer raised portion by connecting wall part energy screw thread separately, the first half does not connect, by pouring liquid into, make liquid slow excessive, adding liquid from one week, is a kind of structure adding liquid newly.
In a creative way, each effect above independently exists, and can also complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure realizes realizes, if do not consider the technical scheme of adding, this patent title can also be a kind of container.Not shown part details.
It should be noted that, multiple schemes that this patent provides comprise basic scheme own, separate, mutually do not restrict, but it also can combine when not conflicting mutually, reaching multiple effect and jointly realizing.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
