Abstract
The utility model provides an electric perforating device for rubber plugs, and belongs to the field of chemical experiment instruments. The device comprises an electric perforator and a base matched with the electric perforator. The base comprises a base body and a plate body, wherein the base body and the plate body are connected through a spring, a rubber plug containing part is arranged in the center of the plate body, and the rubber plugs can be contained in the rubber plug containing part. When the rubber plugs need to be perforated, the rubber plugs are placed in the rubber plug containing part, and the rubber plugs can be prevented from moving back and forth. The spring is arranged between the plate body and the base body and is vertically arranged, the spring will extrude the rubber plugs when the electric perforator performs perforation, at the moment, the plate body will be pressed downward to generate downward force, but the spring has upward force, therefore the rubber plugs can be prevented from moving better through the extrusion, the rubber plugs are more favorable for being fixed, and the problem that perforation is prone to deviation is solved.
Description
Technical field
The utility model relates to a kind of perforating device, the especially a kind of plug of the motor-driven eraser for chemical experiment perforating device.
Background technology
In chemistry teaching or chemical experiment; often can run into rubber stopper and seal bottleneck; perhaps in order to test required meeting, to rubber stopper, punch; existing drilling method is generally: rubber stopper is placed on experimental bench, then uses card punch to be punched, existing card punch is handle of top band normally; centre is cylinder cutter cylindraceous; while being punched, hold the handle place, then firmly punched according to the mode of rotating down pressing.
Because needs adopt the mode of rotating down pressing, punched, punching is not only lost time, and not only loaded down with trivial details but also require great effort; Mode by rotating down pressing is punched, and the hole of sometimes being up to can train off, and can have influence on the air-tightness of later experiments.
As can be seen here, prior art awaits development and progress.
The utility model content
In order to solve problems of the prior art, the utility model proposes a kind of motor-driven eraser plug perforating device, it is not only laborsaving but also solved the problem trained off on the basis of existing technology.
The technical solution of the utility model comprises:
A kind of motor-driven eraser plug perforating device, described perforating device comprises electric perforator and the base matched with electric perforator, described electric perforator comprises drill bit and switch, described base comprises base body and plate body, described plate body is arranged on the top of described base body, between described base body and plate body, by spring, connects; Also be provided with the rubber stopper placement section on described plate body.
Above-mentioned rubber stopper placement section is positioned at the center of described plate body.
Above-mentioned rubber stopper placement section is inverted cone-shaped.
The useful technique effect that the utility model brings:
The utility model proposes a kind of motor-driven eraser plug perforating device, this device comprises electric perforator, electric perforator energising can be punched to rubber stopper, has overcome in the prior art the not only hole knockout of loaded down with trivial details but also effort, the base matched with this electric perforator, this base comprises base body and plate body, between its base body and plate body, by spring, connect, be provided with the rubber stopper placement section in the center of plate body, the rubber stopper placement section can hold rubber stopper, when needs are punched to rubber stopper, rubber stopper is positioned over to the rubber stopper placement section, can avoid moving around of rubber stopper, be provided with spring between plate body and base body, this spring is vertical the setting, when electric perforator punches, can push rubber stopper, at this moment plate body can be to lower compression, produce the power of a downward direction, and spring has the power of a upward direction, such extruding can better prevent the movement of rubber stopper, more be conducive to the fixing of rubber stopper, solved the problem that punching easily trains off.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of motor-driven eraser plug perforating device, this perforating device comprises electric perforator 2 and the base matched with electric perforator 2, and this electric perforator comprises drill bit 1 and switch 3, and this drill bit 1 is detachable, more bit change 1 is to meet the demand of different pore size, switch 3 is for controlling electric perforator 2, when needs are punched to rubber stopper, and starting switch 3, when not needing to punch, cut-off switch 3; This base comprises base body 4 and plate body 5, plate body 5 is arranged on the top of base body 4, between base body 4 and plate body 5, by spring 7, connect, when rubber stopper is punched, because power straight down reaches plate body, the spring that is positioned at the plate body below is subject to power straight down, in compressive state, spring in compressive state also has the power of a upward direction to plate body 5, such extruding can better prevent the movement of rubber stopper, more be conducive to the fixing of rubber stopper, solve the problem that punching easily trains off; Also be provided with rubber stopper placement section 6 on this plate body 5, when rubber stopper is punched, rubber stopper be placed on to the rubber stopper placement section, can prevent that rubber stopper from moving left and right.
Preferably, above-mentioned rubber stopper placement section 6 is positioned at the center of plate body 5.
Preferably, above-mentioned rubber stopper placement section 6 is inverted cone-shaped.
When needs are punched to rubber stopper, at first rubber stopper is positioned over to the rubber stopper placement section, then starting switch, electric perforator is punched to rubber stopper vertically downward, extruding between plate body 5 and spring can prevent that rubber stopper from moving left and right, this motor-driven eraser plug perforating device, not only laborsaving but also solved the problem that pore volume easily trains off.
It should be noted that, under the instruction of this specification, those skilled in the art can also make such or such variation, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within protection domain of the present utility model.
