Description
Technical field
Counter balance technical field is the utility model is related to, specially a kind of adjustable laboratory balance.
Background technology
Balance is the instrument for weighing mass of object, is also counter balance in the narrow sense, what is commonly used in laboratory is exactly this
Kind counter balance, in the education of modernization, school needs to carry out some simple Physical Experiments, such as the title of solid, liquid
Amount, and these just need to use counter balance, well-known school possesses countless student, while balance is also one
Kind very accurate, sensitive physical experiment apparatus, the counter balance of prior art have a fixed maximum capacity scope, and one
Denier, which exceedes this scope, can not just weigh, and so result in needs multiple counter balances when weighing some heavier experiment products
Weighed, not only inconvenient but also waste of resource.
Utility model content
The technical problem that the utility model solves is to overcome prior art to be inconvenient to carry and can not to weigh some heavier
A kind of the defects of trial target, there is provided adjustable laboratory balance.Adjustable laboratory balance not only have be convenient for carrying and
The features such as some heavier trial targets can be weighed.
To achieve the above object, the utility model provides following technical scheme：A kind of adjustable laboratory balance, including it is outer
Shell and the arm beam of steelyard, the intracavity bottom of the shell are provided with electric expansion bar, branch are installed with the top of the electric expansion bar
Seat, the top of the bearing are provided with support column, and the support column is through case surface and extends to top, the support column
Top is installed with bearing, and the outer wall of the bearing is installed with fixture block, and the front of the arm beam of steelyard offers some and card
The neck that block matches, some blind holes are provided with the top of the arm beam of steelyard, pallet, the top of the arm beam of steelyard are plugged with the blind hole
Portion is additionally provided with graduated scale, and the fluting to match with the arm beam of steelyard and pallet, the top of the shell are offered at the top of the shell
Side wall is connected with top cover by hinge.
Preferably, some necks and blind hole linear arrangement successively from left to right, and each neck and blind hole
Position is respectively positioned on same face.
Preferably, the bearing is quadrangular structure, and the quantity of rest base electric expansion bar is no less than four.
Preferably, the quantity of the pallet is no less than two, and pallet is in funnel-form.
Preferably, the lock to match with shell is provided with the top cover.
Compared with prior art, the beneficial effects of the utility model are：Not only it is convenient for carrying but also weighing can be adjusted
Maximum weight.When the counterweight weight on pallet is inadequate, the arm of force of the arm beam of steelyard can be adjusted by adjusting the diverse location of bearing
Length, heavier experiment product is weighed so as to realize；By adjusting the position of pallet heavier experiment product can also be weighed to realize.
