Description
Technical field
The invention belongs to equipment of chemical industry technical field, specially a kind of punch of use for laboratory.
Background technique
Punch is chemical laboratory common tool, is mainly used for rubber stopper central punch.Glass apparatus in chemical experiment
Between be often required to be attached with the rubber stopper for being equipped with aperture, therefore being punched on rubber stopper with punch is specialty chemical student
The technical ability that must be grasped.
The common punch of chemical laboratory is a hollow metal bar at present, and one end is a circular open, other end two sides
Extend outwardly as handle.In use, hand catches handle, punch is rotated, and to promoting inside rubber stopper, use this punching
There are problems to have for device: 1. a punch can only beat a kind of bore, need to be equipped with the punch of multiple and different specifications in laboratory
Ability meet demand, makes troubles to user；2. existing punch punched hole hole is cylinder, hole bore must be with
Conduit is equal in magnitude be just able to satisfy it is real it is strategically located and difficult of access ask, but be difficult to accomplish that hole bore is equal in magnitude with conduit in reality, bore is big
, conduit is poorly sealed with hole, influences experimental result, and bore is small, and conduit is difficult to be inserted into hole；3. existing punch needs
Punch is operated on the other hand, another hand handle holds rubber stopper, and by exerting oneself, unevenness can make punched hole irregular, not meet experiment
It is required that.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention provides a kind of punch of use for laboratory.
The technical scheme adopted by the invention is that: a kind of punch of use for laboratory, it is characterized in that: the punch includes branch
Frame, knife cut component, clamp assemblies；

N radial holes are uniformly arranged in opening, on box cover；The disk is arranged in lock cylinder, the shaft of disc centre and lock cylinder bottom
Rotation connection, manpower can be driven disk rotational by the notch in lock cylinder, n curved line hole are uniformly arranged in disc face, and n bent
Lines hole is uniformly distributed in the shape of a spiral on disk, and circumferentially arranged scale in disc face, human eye can pass through the notch in lock cylinder
Watch the scale on disk；The sliding block is n, and n sliding block is evenly distributed between disk and box cover, and one end of sliding block is inserted
Enter in disk curved line hole, in other end insertion radial hole of box cover of sliding block, sliding block is under the driving of disk along box cover radial direction
The sliding of hole；The sharpener is n, and n sharpener is evenly distributed in front of disk and is fixedly connected with n sliding block, and sharpener is length
Bar shaped, outwardly, sharpener is tilted from connecting pin to top in the center that moves closer to the blade of sharpener, that is to say, that n sharpener is enclosed
At space be truncated cone-shaped；
The clamp assemblies are used to clamp different size rubber stopper, and it is opposite so that the center of rubber stopper and knife is cut component center, presss from both sides
Holding component includes slide bar, screw rod, grip block；The slide bar is fixed on the base；The screw rod lower end is rotatably connected on pedestal,
Upper section screw thread and lower section screw thread are equipped with screw rod week, the spiral of upper section screw thread and lower section screw thread is on the contrary, screw rod upper end is equipped with
Handle；The grip block includes upper grip block and lower grip block, and one end of upper and lower grip block is equipped with slide opening and is set on slide bar,
The other end of upper and lower grip block is equipped with nut, and upper grip block nut is matched with screw rod upper section screw thread, lower grip block nut and spiral shell
Bar lower section screw thread matches, and rotates screw rod, and upper and lower grip block is displaced in the opposite direction, and the space that upper and lower grip block is surrounded is folder
Hold space, it is opposite that grasping part center with knife cuts component center.
Further, the crank is equipped with turning handle.
Further, the disc circumference is equipped with anti-skid chequer.
Further, the n is 3~8.
Further, the opposite side of the grip block up and down is arc.
The course of work of the present invention: rubber stopper is fixed on clamp assemblies, is adjusted knife as needed and is cut component sharpener bore
Size, finger drive disk rotational by the notch in lock cylinder, and disk driving sliding block slides on radial hole of box cover, sliding block band
Dynamic sharpener is mobile, and the sharpener caliber size that several sharpeners surround changes, since sharpener caliber size depends on disk
Rotational angle, therefore the scale on disk can be used to indicate sharpener caliber size.Crank is rotated with hand, crank drives silk axis to turn
Dynamic, silk axis band moving knife cuts component rotation, meanwhile, the internal screw thread on silk axis and riser cooperates, silk axis push knife cut component to
Preceding displacement, knife are cut component and are punched to rubber stopper.Since sharpener is to be obliquely installed, getting hole to rubber stopper is truncated cone-shaped.Reversion
Crank, knife are cut component reversion and are retreated, exit from rubber stopper.
The medicine have the advantages that 1. knife cut punching bore it is adjustable, a punch can beat the bore of various specifications, give
User brings convenience；2. punched hole hole is truncated cone-shaped, it is easy to hole is inserted the catheter into, meanwhile, conduit and hole seal,
Experiment is helped to smoothly complete；3. being equipped with rubber stopper clamp assemblies, be capable of clamping different size rubber stopper, and make the center of rubber stopper with
It is opposite that knife cuts component center, takes rubber stopper to punch than hand safer, punching will not be inclined；4. component is cut with crank driving knife, than passing
System punch is easier to operate to, and more labor-saving, more rapidly, punched hole hole more standardizes.
