A kind of use for laboratory physics sander
Technical field
It is polished in the experiment used the invention belongs to field of experiment equipment more particularly to a kind of suitable student's study with physics
Machine.
Background technology
Whether the thinking of people has an objective truth, the problem of this is not a theory, but practice is asked
Topic.People should prove the actuality and strength of the truth of oneself thinking, i.e. oneself thinking in practice, that is, oneself thinking
This sideness.The problem of whether on the thinking for leaving practice there is the arguement of actuality, be a pure experience philosophy.Student exists
In learning process, depth and the manipulative ability of practical operation are understood in order to improve it, experiment is essential, without one
Item invention is createed and without experiment.
Particularly the important so dynamics for increasing experiment seems, but now in society, to the protection of student progressively
It increases, teacher parent worries the safety problem of student one by one so that experiment can not smoothly be carried out progress always, in order to carry
Security in high experimentation expands the dynamics of experiment it is necessary to carry out " laboratory " to used product in the market.
Student is vulnerable group, is very easy to damage in testing in the case where the experience of quarrelling and fighting noisily lacks, so
The object of the present invention is to provide the sander in a " laboratory ", to provide student experimenting, study and use.
The content of the invention
The present invention proposes a kind of use for laboratory physics sander, and including protective shell, polishing dress is equipped in the protective shell
It puts, the protective shell is provided with transparent observing window, and mobile mouth, the sanding apparatus bag are provided in the watch window lower end
Grinding stone, fixing device and rotating device are included, the rotating device is mounted on the protective shell roof centre position, the fixed dress
Top set end is bolted with the rotating device, and the fixing device is flexibly connected with the grinding stone;
Grain-clamping table has been further included, clip is installed on the grain-clamping table, described grain-clamping table one end is provided with and the movement
The handle that mouth is adapted.
Wherein, the fixing device lower surface, which is provided with, can paste the double faced adhesive tape that grinding stone is stated in residence.
Wherein, gripper jaw is additionally provided in the fixing device, the gripper jaw quantity is 3.
Wherein, the grain-clamping table upper surface is provided with double faced adhesive tape.
Wherein, the watch window is equipped with the acrylic board of high transparency.
Wherein, the protective shell lower surface is provided with clump weight, and the clump weight is structure as a whole with the protective shell.
Wherein, the protective shell lower end is provided with the rubber pad of damping and slide-prevention effect.
Beneficial effects of the present invention:By dexterously designing, danger involved in student experimenting is avoided, is learned improving
While lively hand operative skill, student's unexpected injury caused by due to the use of lacking experience sufficiently is avoided.
Description of the drawings
Fig. 1 is a kind of structure diagram of use for laboratory physics sander of the present invention;
Fig. 2 is a kind of external structure schematic diagram of use for laboratory physics sander of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1 to 2, a kind of use for laboratory physics sander, the protective shell 1 including providing protective effect, the guarantor
Sanding apparatus is installed, the protective shell is provided with transparent observing window 101, and student can be seen by observation window in protective case 1
It examines the progress of polishing or is adjusted polishing orientation, the watch window lower end is provided with mobile mouth 102, the polishing
Device includes grinding stone 2, fixing device 3 and rotating device 4, and the rotating device 4 is mounted on the 1 roof interposition of protective shell
It puts, 3 top of fixing device is bolted with the rotating device 4, the fixing device 4 and 2 activity of grinding stone
Connection;The rotating device 4, which rotates, to be driven by the fixed grinding stone 2 of the fixing device 3, the grinding stone 2 to polishing part into
Row polishing.
The grain-clamping table 5 for fixing polishing part is further included, the folder that can clamp polishing part is installed on the grain-clamping table 5
Son 6, described 5 one end of grain-clamping table are provided with the handle 7 being adapted with the mobile mouth 102, and the handle 7 is arranged on the movement
Mouthfuls 102 outside, by controlling the handle 7 in outside, so as to control the grain-clamping table 5, so as to controlling polishing
Direction, dynamics etc..
In some optional embodiments, 3 lower surface of fixing device, which is provided with, can paste pair that grinding stone 2 is stated in residence
Face glue, the double faced adhesive tape can be cleaned, be used for multiple times.
In some optional embodiments, in order to improve security performance, prevent grinding stone from dropping, in the fixing device 3 also
Gripper jaw 301 is provided with, 301 quantity of gripper jaw is 3.
In some optional embodiments, 5 upper surface of grain-clamping table is provided with double faced adhesive tape, and the double faced adhesive tape can be clear
It is clean, it is used for multiple times.
It in some optional embodiments, prevents in bruting process, discarded object, which dances in the air, damages student, the observation
Window 101 is equipped with the acrylic board of high transparency.
It is described in order to improve a kind of operation stability of use for laboratory physics sander in some optional embodiments
1 lower surface of protective shell is provided with clump weight 8, and the clump weight 8 is structure as a whole with the protective shell 1.
In some optional embodiments, 1 lower end of protective shell is provided with the rubber pad 9 of damping and slide-prevention effect.
Above-described embodiment is the preferable embodiment of the present invention, but embodiments of the present invention and from above-described embodiment
Limitation, other are any without departing from the change made under Spirit Essences and principle of the invention, modify, substitute, combine, simplify,
Equivalent substitute mode is should be, should all be included within the scope of the present invention.
