Description
Technical field：
The present invention relates to the technical field of middle school teaching instrument, is specifically related to the pallet day that a kind of middle school teaching uses
It is flat.
Background technology：
Counter balance is one of requisite instrumentation in laboratory in middle school teaching, and it uses the primary Weir principle of sieve to be made, the scale pan
In baseplane stress, in a kind of balance that non-central location can move to center automatically and form.Counter balance mainly wraps
Base, intermediate slide, vernier, the lever with scale, pallet etc. are included, pallet is arranged on lever both ends by suspension bracket, and suspension bracket lower end is set
There is perpendicular support arm, perpendicular support arm can be stretched into downwards on base in corresponding hole, and the perpendicular support arm periphery below pallet is provided with protection knife rest and used
Gum cover, it is fixed on by gum cover on base in corresponding fixing hole.Existing counter balance is before use, need two pallets
Following Protection glue set is removed, could normal use.In order to protect the edge of a knife after use, avoid the edge of a knife in running order,
Also gum cover is reinstalled, so can just enter cabinet placement, this mode installing/dismounting gum cover is wasted time and energy, and gum cover also holds
Easy to be lost or damage, causes counter balance is in running order to be placed, is easily damaged the edge of a knife, the accuracy of counter balance is big
It is big to reduce, it can also have a strong impact on the effect of teaching experiment.
The content of the invention：
The purpose of the present invention aims to solve the problem that the problem of prior art is present, there is provided a kind of effectively to protect knife when placing
Mouthful, the counter balance that the middle school teaching for avoiding the edge of a knife from damaging uses.
The present invention relates to the counter balance that a kind of middle school teaching uses, including base, intermediate slide, the lever with scale and support
Disk, the pallet are arranged on the both ends of lever by the suspension bracket, and suspension bracket lower end, which is provided with, erects support arm, on the upper surface of the base
Jack is formed, the lower end of the perpendicular support arm is stretched into the jack, and the bottom of perpendicular support arm is provided with the first magnet, is set below jack
Have rotating disk of the plugged and fixed on fulcrum, form some double wedges in the cylindrical side wall of the rotating disk, on some double wedges between
Every one end provided with the second magnet and the 3rd magnet, second magnet and the first magnet be heteropole, the 3rd magnet and
One end of one magnet is homopolarity, and the bottom of jack forms through hole, and the second magnet is plugged in the through hole, and through hole side is inserted
Bottom hole portion forms the link slot communicated with rotating disk, and limiting plate is plugged with the link slot, and limiting plate upper sleeve has spring, institute
The both ends for stating spring are separately fixed on the inwall and limiting plate of link slot, when the first magnet and attracting the second magnet, erect branch
Arm is pressed against on limiting plate and the lower end holding of limiting plate is on rotating disk between two neighboring double wedge, and now spring is become by compression
Shape；
External screw thread is formed on the outer wall of the perpendicular support arm, perpendicular support arm upper sleeve, which is bolted with, to be pressed against on base upper surface
Adjustment gear, annular groove is formed on the base upper surface of the jack surrounding, is formed on the bottom surface of the adjustment gear slotting
The spacing ring being connected in the annular groove, the side of adjustment gear are engaged with horizontal rack, two regulation teeth of base both sides
Wheel engages the both sides for being connected to the rack respectively, forms resettlement groove on the upper surface of base, rack is plugged on the placement
In groove, the both ends inwall of resettlement groove is provided with magnet layer, and the both ends of rack are provided with iron layer.
By above-mentioned technical proposal, in the use of the present invention, the second magnet on rotating disk is plugged in the through hole of jack, erect
First magnet adsorption of support arm bottom is on the second magnet, and perpendicular support arm is pressed against jack bottom and is pressed against on limiting plate, limits
Spring on the plate of position by compression and the lower end holding of limiting plate on rotating disk between two neighboring double wedge, limiting plate it is spacing
Effect causes rotating disk to be not easy indexing, now erects support arm and is fixed in the jack of base, in addition, the iron layer of rack one end is inhaled
It is attached on the magnet layer of resettlement groove one end, rack is fixed so as to which adjustment gear be fixed, and perpendicular support arm further is fixed on into base
Jack in, such counter balance can normal use.After use, firmly the adjustment gear on rotating vertical support arm, is adjusted
The spacing ring of section gear rotates in the annular groove of base and will be spacing above and below adjustment gear, so as to which adjustment gear drives perpendicular support arm
Move up, after the first magnet of perpendicular support arm separates with the second magnet of rotating disk, limiting plate also due to spring force effect and answer
Double wedge is left in position, the lower end of limiting plate, and then rotating fulcrum causes rotating disk to rotate an angle, so that the 3rd magnet is plugged on
In the through hole of jack, due to the 3rd magnet and the first magnet homopolarity mutual exclusion, therefore support arm is erected because magnetic force is in picking-up state, and
Adjustment gear band carry-over bar when rotating moves to the resettlement groove other end, and the transmission of rack causes two regulation teeth of base both sides
Wheel rotates in same direction together, so that two perpendicular support arms synchronously move up, when the iron layer of rack the other end is attracted to resettlement groove
During the magnet layer of one end, adjustment gear and perpendicular support arm are fixed again, and are now erected support arm and entered while being held up by magnetic force
One step is fixed, and so as to which suspension bracket be held up, suspension bracket again can hold up the lever with scale, three edges of a knife is departed from working face, from
And avoid each edge of a knife in running order, effectively protect the edge of a knife.
By such scheme, the counter balance that middle school teaching of the invention uses can depart from three edges of a knife when placing
Working face, so as to effectively protect the edge of a knife, the edge of a knife is avoided to damage.
One kind as such scheme preferably forms hinged groove in the base below the jack, the hinged groove
Arc groove is formed in upper end wall, the upper end of the rotating disk is plugged in the arc groove, and arc groove is connected with the through hole of jack
Logical, one end of the fulcrum is hinged on the inwall of hinged groove, the other end stretches out the lateral wall of base.
Preferably, the center of circle of the arc groove overlaps one kind as such scheme with the center of circle of rotating disk and the center of circle is located at fulcrum
On.
One kind as such scheme preferably forms some limited blocks, the spacing ring on the inwall of the annular groove
Side wall on form annular projection, the limited block is pressed against on the annular projection, and wearing layer is formed on spacing ring, institute
State the inwall that wearing layer is close to annular groove.
Preferably, the link slot and limiting plate are in vertical shape to one kind as such scheme, and the lower end of link slot is molded
There is a step, the lower end of the spring is fixed on the step, upper end is fixed on limiting plate, when spring is in nature, limit
Link slot is stretched out in the top and bottom of position plate.
Preferably, the quantity of the rotating disk upper raised teeth is even number to one kind as such scheme.
