Abstract
The utility model relates to a counter balance which comprises a base, a middle cutter, a lever with a scaleplate and pallets, wherein the pallets are installed at both ends of the lever through a hanger of which the lower part is provided with a vertical support arm, and the vertical support arm is a guide screw on which a support nut is correspondingly arranged. The support nut of the utility model can move up and down along the guide screw-shaped vertical support arm; when the support nut is regulated to the upper part of the guide screw, the counter balance can be normally used. After the utility model is used, the support nut is regulated to the lower part of the guide screw so that the hanger can be supported to make the cutting edges separate from the working surfaces, and thus, the cutting edges are not in the working state. The utility model is simple in structure and convenient in regulation and can effectively protect the cutting edge during placement.
Description
Technical field
The utility model relates to a kind of weighing measuring apparatus, specifically a kind of counter balance.
Background technology
We know that counter balance is a kind of instruments used for education commonly used in the physics teaching in secondary school, also are weighing measuring apparatus of using always in the life.It mainly comprises lever, pallet of base, intermediate slide, vernier, band scale etc.; pallet is installed in the lever two ends by suspension bracket; the suspension bracket lower end is provided with perpendicular support arm; perpendicular support arm can stretch into downwards on the base in the corresponding hole; perpendicular support arm periphery below the pallet is provided with protection knife rest gum cover, is fixed on the base accordingly in the fixed orifice by gum cover.Existing counter balance need take off the protection gum cover below two pallets before use, could normally use.Finish using the back in order to protect the edge of a knife, avoid the edge of a knife in running order, also gum cover will be loaded onto again, place just can go into cabinet like this.The gum cover troublesome poeration is often unloaded, installs in use, waste time and energy, and gum cover is also lost easily or damaged, cause the in running order placement of counter balance, damage the edge of a knife, the degree of accuracy of counter balance reduces greatly, also can have a strong impact on the effect of education experiment.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to adjust, can protect the counter balance of the edge of a knife during placement effectively.
The technical scheme in the invention for solving the above technical problem is: a kind of counter balance, comprise base, intermediate slide, the lever of band scale, pallet, pallet is installed in the lever two ends by suspension bracket, the suspension bracket lower end is provided with perpendicular support arm, it is characterized in that: perpendicular support arm is a screw mandrel, correspondingly is provided with holding nut on it.
The utility model holding nut can move up and down along the perpendicular support arm of screw mandrel shape, and holding nut is adjusted to screw mandrel top, and counter balance just can normally use.After finishing using, holding nut is adjusted to the screw mandrel bottom, conflict tightly on base, just can make each edge of a knife break away from workplace picking-ups such as suspension bracket until it.Against existing technologies, the utility model is simple in structure, and is easy to adjust, can protect the edge of a knife effectively during placement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. bases among the figure, 2. intermediate slide, the 3. lever of band scale, 4. pallet, 5. suspension bracket, 6. leveling nut, 7. perpendicular support arm, 8. holding nut.
Embodiment
As can be seen from Figure 1, a kind of counter balance comprises lever 3, the pallet 4 of base 1, intermediate slide 2, band scale, pallet 4 is installed in the lever two ends by suspension bracket 5, the lever two ends also are provided with leveling nut 6, and suspension bracket 5 lower ends are provided with perpendicular support arm 7, and perpendicular support arm can stretch into downwards on the base in the corresponding hole.Counter balance also is provided with pointer, vernier, counterweight etc. in addition, also is provided with the edge of a knife on intermediate slide 2, the suspension bracket 5.Above-mentioned composition, structure and connection thereof, position concern identical with prior art, are not describing in detail.
Characteristics of the present utility model are: perpendicular support arm 7 is a screw mandrel, correspondingly is provided with holding nut 8 on it.Holding nut 8 can move up and down along the perpendicular support arm 7 of screw mandrel shape.Holding nut 8 is adjusted to screw mandrel top, and counter balance just can normally use.After finishing using, holding nut 8 is adjusted to the screw mandrel bottom of erecting support arm 7, conflict tightly on base until it; just can be with suspension bracket 5 picking-ups such as grade, suspension bracket 5 can make three edges of a knife break away from workplace with lever 3 picking-ups such as grade of scale again; avoid each edge of a knife in running order, protect the edge of a knife effectively.Against existing technologies, the utility model is simple in structure, and is easy to adjust, can protect the edge of a knife effectively during placement.
