Abstract
The utility model relates to a filter paper shearing device, which belongs to the chemical instrument class and particularly relates to a filter paper shearer. The filter paper shearer comprises a ruler body (1) with a scale; the ruler body (1) is provided with a shearing knife (2) which slides along the ruler body (1); a rotation shaft (3) is fixedly connected in the middle of the ruler body (1); and the rotation shaft (3) is rotatably connected with a pressing block (4) positioned at the bottom of the rotation shaft. With the adoption of the technical scheme, the slidable shearing knife is connected to the ruler body with the scale, the filter paper is evened out through the pressing block when round shearing is carried out on the filter paper, and the position of the shearing knife on the ruler body can be adjusted according to the diameter of the needed filter paper, then the ruler body is rotated, and the filter paper is sheared into the required sizes through the shearing knife. The filter paper has high shearing precision and simple structure, and is convenient to use.
Description
Technical field
The utility model relates to a kind of filter paper Scissoring device of chemical apparatuses class, relates in particular to a kind of filter paper clipper.
Background technology
The people who does experiment in the laboratory knows, usually need solid and liquid be separated.A kind of instrument that usually then adopts is exactly a Buchner funnel.But clip filter paper is a burden, should consider that the diameter of filter paper is considered the filter paper radian again.The method of the shearing filter paper that the laboratory is conventional is used scissors exactly.Not justifying of filter paper clip, elapsed time is long again.
The utility model content
For solving the deficiency that exists in the prior art, the utility model provides the filter paper clipper that can carry out accurate tailoring to filter paper, and it is simple in structure, and is easy to use.
For realizing above-mentioned purpose, the filter paper clipper of the utility model comprises the chi body that has scale, on the chi body, is provided with the cutting knife that slides along the chi body, is fixedly connected with rotating shaft at the middle part of chi body, and rotating shaft links to each other with the briquetting that is positioned at its bottom is rotatable.
As the improvement to aforesaid way, described cutting knife is two, and slidably is arranged on respectively on the chi body of rotating shaft both sides.
As further qualification to aforesaid way, slidably be provided with slide block on the chi body, described cutting knife and slide block are connected.
Adopt technique scheme, owing to be connected with slidably cutting knife having on the chi body of scale, the time to the circular cutting of filter paper; Through briquetting filter paper is flattened, the position of diameter adjustment cutting knife on the chi body according to required filter paper rotates the chi body then; Through cutting knife filter paper is cut into required size; Its cutting precision is high, and is simple in structure, easy to use.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify:
Fig. 1 is the overall structure sketch map of the utility model.
The specific embodiment
Known that by shown in Figure 1 the filter paper clipper of the utility model comprises the chi body 1 that has scale, chi body 1 centre position is a zero graduation, and the symmetry mark has size scale on the chi body of these zero graduation both sides.Zero graduation fixed-site at chi body 1 is connected with rotating shaft 3, and the bottom of this rotating shaft 3 and 4 rotatable linking to each other of briquetting this can be seen that, in order to strengthen the rotating effect of rotating shaft 3 relative briquettings 4, can set up bearing between the two.The chi body 1 that is positioned at rotating shaft 3 both sides is provided with the slide block 5 that slides along chi body 1, and the bottom of slide block 5 is fixedly connected with cutting knife 2, cuts being used to of the bottom of cutting knife 2 that cutting of filter paper is tough should to be maintained at the same horizontal plane with briquetting 4.
In use; Position according to two slide blocks 5 about required filter paper diameter adjustment; Realized the confirming of distance between two cutting knifes 2 is pressed in the filter paper surface with briquetting 4 then through the position of adjustment slide block 5, driven 2 pairs of filter paper of cutting knife through rotary ruler body 1 and carry out circle cutting.It is simple in structure, and is easy to use.
Claims (3)
1. filter paper clipper; Comprise the chi body (1) that has scale; It is characterized in that: on chi body (1), be provided with the cutting knife (2) that slides along chi body (1); Be fixedly connected with rotating shaft (3) at the middle part of chi body (1), rotating shaft (3) links to each other with the briquetting (4) that is positioned at its bottom is rotatable.
