Abstract
The utility model relates to a portable no-weight pull-rod balance, which is a steelyard for measuring the weight of an object in daily life. The purpose of the utility model is to provide an improved steelyard for daily life; the portable no-weight pull-rod balance is quite convenient to be carried. The balance bar of the steelyard is turned into pull-rod type by the portable no-weight pull-rod balance; the portable no-weight pull-rod balance is formed by that an inner and an outer two sections of metallic balance bars are mutually sheathed; the weight is replaced the inner balance bar. When weighing heavy objects, the inner balance bar is pulled, because the gravity center of the inner balance bar is moved, the whole balance can be made to be in a balanced state; the weight of the weighing object is given by scales marked on the inner and the outer balance bars. Because of the length of the balance bar being shortened and no weight, the portable no-weight pull-rod balance is quite convenient to be carried in normal times.
Description
The utility model is that a kind of daily life of measuring weight of object claims with bar.
At present, the weight of daily life vacuum metrics object claims with rod mostly, because that rod claims is easy to use, make simple, low price, so use very general.But because the weighing lever that rod claims is longer, and be that wood is done, adding has to claim a stone roller in addition, so the inconvenience of carrying if careless weighing lever also fractures easily, claims stone roller to lose easily.
The purpose of this utility model is to claim that with bar it carries very convenient for people provide a kind of improved daily life.
The purpose of this utility model is achieved in that the weighing lever that bar claims makes rod-pulling type into, and being nested by inside and outside two joint metal weighing levers forms, and claims stone roller to be replaced by interior weighing lever.When weighing thing, weighing lever in twitching, because moving of interior weighing lever center of gravity just can make whole title be in equilibrium state, the weight of alleged object is just provided by the scale that is marked on the inside and outside weighing lever.Because the length of weighing lever shortens greatly, and does not have the stone roller of title, so carry very convenient at ordinary times.
The utility model makes weighing lever into rod-pulling type owing to needing only, and is replaced claiming stone roller by interior weighing lever, so simple in structure.As long as select suitable metal pipe and La Guangyuan, make and draw the light garden in metal tube, can be free to slide, carry out simple machining then and just can manufacture.
The concrete structure of utility model is provided by following examples and accompanying drawing.
Fig. 1 is the sectional view that claims according to the portable nothing stone roller pull bar that the utility model proposes.
Describe structure of the present utility model and operating position in detail below in conjunction with Fig. 1.
This utility model is by outer weighing lever 1, and interior weighing lever 2 shakes hands 3, and register pin 5 claims hook 8, claims knob 9 and claims knob 10 compositions.
The weighing scale is carved with in the top on the surface of weighing lever 1 and interior weighing lever 2 outside.Weighing lever 2 in twitching, when whole bar claimed to be in equilibrium state, the weight of weighed object was indicated by the end face C of the side 4 of handle 3 or outer weighing lever 1.
For the twitch scope of weighing lever 2 in enlarging,, open an elongated slot 6 outside on the weighing lever 1 to increase the range of weighing of weigh-beam.
Because locating slot 7, register pin 5 and elongated slot 6, the effect of handle 3 when interior weighing lever 2 is twitched in the weighing lever 1 outside, can not rotate.
When twitching in the weighing lever 1 outside, can be free to slide, should make the internal diameter big 0.1mm～0.2mm of the internal diameter of outer weighing lever 1AB section than BC section for weighing lever 2 in making.
Point 11 places are for claiming minimum weighing place of knob 9, i.e. zero point.
When the limit site 12 moves to register pin 5 places, obtain claiming the maximum capacity of knob 9.
When limit site 12 when moving to register pin 5 places, obtain claiming the maximum capacity (i.e. this bar claim maximum capacity) of knob 10.
Because the maximum capacity that claims of bar is by weight, the length of outer weighing lever 1 and interior weighing lever 2 and claim hook 8 and claim the distance decision of 9,10 on knob.So select suitable outer weighing lever 1 and interior weighing lever 2, change the distance that claims hook 8 and claim 9,10 on knob, just can make the different series of range of weighing and claim.
Claims (5)
1, a kind of portable nothing stone roller pull bar claims, it is characterized in that weighing lever is a rod-pulling type, be nested by weighing lever 2 in outer weighing lever 1 of metal and the metal and form, claim stone roller to replace by interior weighing lever 2, when weighing thing, weighing lever 2 in twitching is because interior weighing lever 2 centers of gravity is mobile, just can make whole title be in equilibrium state, the weight of alleged object is just provided by the scale that is marked on the inside and outside weighing lever.
2, bar according to claim 1 claims, it is characterized in that the weighing lever that bar claims is a rod-pulling type, and being nested by weighing lever 2 in weighing lever in the metal 1 and the metal forms.
3, bar according to claim 1 claims, it is characterized in that the title stone roller that bar claims is replaced by interior weighing lever 2.
4, bar according to claim 1 claims, it is characterized in that having an elongated slot 6 on the weighing lever 1 outside.
5, bar according to claim 1 claims, it is characterized in that the internal diameter big 0.1mm～0.2mm of the internal diameter of outer weighing lever 1AB section than BC section.
