Description
Technical field
The utility model belongs to physical experiment apparatus, and in particular to a kind of weight beam.
Background technology
Weight beam is a kind of instrument of the size of dynamometry, and its operation principle is：Measurement any first is all will be a certain
Individual physical quantity and standard（That is unit）The process compared, the measurement of power are exactly the action effect by the action effect of power and known force
The process compared.If the action effect of a power is identical with 1 Niu Li action effect, the size of this power is exactly 1 N.Secondly
The elongation of spring is directly proportional to the size of institute stress, it is determined that after 1 Niu Li action effect, in this way it is easy to determine bigger power and more
The action effect of small power.In addition, the stability of spring is preferable, may be reused.Therefore weight beam can be used to measure
The size of power.
The weight beam used now mostly includes spring, hook, dial, suspension ring and pointer, and is mostly to use
In physics teaching, when student is measured using present weight beam to object, just object is hung over and surveyed on hook
When measuring, and being measured using present weight beam, it is required for people then to be existed again with the clasp of portable firmly weight beam greatly
Object under test is hung on hook, if weight beam below hang with heavier object, it is necessary to for a long time lift observation total indicator reading when,
With regard to relatively harder, arm is also easily aching and limp, although some uses nail on nail on the wall, weight beam is then hung over nail
Son, such student avoid the need for being gone to hold weight beam with hand, and it is aching and limp to avoid arm, but larger when measuring some volumes
Object when, because the length of nail is fixed, so the distance between dial and metope are fixed, object is too big
When will be contacted with metope, it is inaccurate so to may result in measurement.
Utility model content
The utility model is intended to provide a kind of weight beam, to solve in the prior art between weight beam and wall
Spacing it is constant the problem of.
A kind of weight beam in this programme, including spring, dial, suspension ring and pointer, the suspension ring are connected to quarter
The top of scale, the spring are located on dial, and one end of the spring connects with suspension ring, the other end of the spring and refer to
Pin is connected, and hook is connected with below the pointer, and the back side of the dial is vertically connected with sleeve, slided in the sleeve
Connecting rod is connected with, the sleeve is provided with chute, and the chute is provided with the propulsion handle for connecting rod of stretching, the sleeve
Upper one end away from dial is provided with neck, and the neck is provided with the movable buckle for fixed connecting rod；The connecting rod
It is provided with sucker.
Operation principle of the present utility model：
Weight beam in the utility model, in use, because the back side of dial is vertically connected with sleeve, in sleeve
Connecting rod is slidably connected, sleeve is provided with chute, and chute is provided with the propulsion handle for connecting rod of stretching, and promotes and promotes handle will
Connecting rod is released, and one end away from dial is provided with neck on sleeve, and neck is provided with the active card for fixed connecting rod
Button, after connecting rod is pushed into suitable position, reuses movable bayonet and fixes connecting rod, and connecting rod is provided with sucker, will
Whole device can be just suspended in the air, then hung on hook on the wall or on desk by sucker paster by the absorption affinity of sucker
Upper object under test.
The beneficial effects of the utility model：
, just can be by weight beam by the sucker in connecting rod when being measured using the weight beam in this programme
It is fixed on the wall or on desktop, student using when avoid the need for being gone to hold weight beam with hand, it is aching and limp to avoid arm；It is logical
The pushing handle crossed on sliding sleeve chute is suspended in the air with regard to that can adjust the length of connecting rod with regard to the dial that can make weight beam
And maintained a certain distance with metope, when measuring some volume larger objects, just effectively avoid object and contacted with metope,
Measurement is just more accurate.
Further, the dial is provided with wearing layer.After hanging up object on hook, spring will deform upon, will
Rub with dial, use for a long time, the scale-wearing on dial will can be influenceed reading unavoidably；On dial
Provided with wearing layer, scale is just avoided as far as possible and is worn, avoid such situation and occur.
Further, the sleeve and dial detachable connection.After student completes experiment using the device, it is necessary to will
Weight beam consolidation is good, and sleeve is arranged on the back of dial, with regard to bad placement when placement；Sleeve is removable with dial
Formula connection is unloaded, sleeve can just be removed and be placed again, it is thus more convenient.
Further, the hook is provided with pallet., cannot be by object using hook when measuring some irregular objects
Hang up, hook is provided with pallet, facilitates and puts up some irregular objects, just more convenient during measurement.
