Abstract
A balance for physics teaching in the utility model relates to an appliance for teaching experiments. The balance is composed of a pedestal, pallets, a crossbeam, a support, a pointer and a fan-shaped ruler, wherein the support is vertically fixed at the center of the pedestal; the crossbeam is hinged to the upper portion of the support; a pallet hanging bracket is respectively connected below both ends of the crossbeam; more than layers of pallets are fixed on the pallet hanging brackets; a screw is respectively and horizontally fixed at two ends of the crossbeam; an adjusting nut is connected at a screw opening of each screw; the fan-shaped ruler is fixed on the top of the support; the pointer is vertically fixed at the center of the crossbeam; height adjusting screws are connected at four corners of the pedestal, perpendicular to the screw openings; and more than one horizontal bubble devices are fixed in the left-and-right direction and in the back-and-forth direction on a table top of the pedestal. The balance for physics teaching has a reasonable structure. According to the utility module, the number of the pallets at two sides is increased, the capability of increasing kinds and number of placed target test objects is improved, overall horizontality of the balance is visually displayed, debugging time is shortened, debugging difficulty is reduced, and time and labor are saved.
Description
Technical field
The utility model relates to a kind of education experiment apparatus, relates in particular to a kind of physics teaching balance.
Background technology
Physics teaching is with a large amount of Physical Experiments, student's seek knowledge interest and manipulative ability when intuitive is strong, have also been increased, balance is one of requisite teaching aid in physics teaching, the normal counterweight balance that uses in teaching, the pallet at current counterweight balance two ends is one group, the determinand that can place is very limited, student's curiosity is stronger, conventionally can in practice process, multiple object be measured simultaneously starting, and the balance of existing single mount dish can not meet student's curiosity, given up student's enthusiasm, balance requires very high to overall level when placing in addition, and existing balance can not intuitively embody accurately, make wastes a large amount of time when debugging.
Summary of the invention
The utility model is for the deficiency existing in background technology, and the physics teaching balance proposing.
Physics teaching balance of the present utility model, by base, pallet, crossbeam, support, pointer and fan-shaped scale form, its base center stands and is fixed wtih support, support upper articulation crossbeam, the below, two ends of crossbeam is all connecting pallet suspension bracket, on pallet suspension bracket, be fixed wtih two-layer above pallet, the two ends of crossbeam are all laterally fixed wtih screw rod, and screw socket is connecting setting nut on screw rod, the top of support is fixed wtih fan-shaped scale, on crossbeam, along middle part, stand and be fixed wtih pointer, four jiaos of base all vertical screw socket connect height adjusting screw rod, on the table top of base, on left and right directions and fore-and-aft direction, be all fixed wtih more than one spirit bubble device.
As of the present utility model preferred, the described both sides that are laterally fixed wtih crossbeam spacing bracket, crossbeam spacing bracket below support entablature all longitudinal screw socket are connecting Limit screw.
Physics teaching balance of the present utility model, rational in infrastructure, increased the quantity of both sides pallets, increase the kind of target detection thing and the ability of quantity of holding, the horizontality of balance entirety is had intuitively and shown, reduced the time of debugging and reduced the difficulty of debugging, time saving and energy saving.
