Abstract
The utility model relates to a hand balance, comprising a main balance bar, and a limit weight, a movable standard weight, a horizontal leveling tube, the function fulcrum of a hand holding ring, a function fulcrum of a weight hook, etc. which are arranged on the upper side of the main balance bar. The weights can not be replaced. The function fulcrum of a hand holding ring and the function fulcrum of a weight hook both adopt knife edge contacts and are protected by a protecting case. The weights of weighing objects are directly marked on the main balance bar. The hand balance has the advantages of simple structure, accurate metering, visual reading, etc. The utility model can be used for the field metering and the civil metering of scientific researches.
Description
The utility model belongs to a kind of scale.
General platform balance or the spring balance of the adopting during metering of scientific research in the open air at present.Because the platform balance volume is bigger, and weight is heavier, and is not portable during field work, needs more smooth place during installation, so promptly time-consuming, and effort is again used very inconvenient and precision is not high; Spring balance then measures out of true, and weighing apparatus commonly used among the people is many with traditional round lever, the star formula scale that adds sliding weight of steelyard then, not high its weight number that directly do not mark of its precision.And error bigger on causing measuring appears easily with the stone roller mistake.
The purpose of this utility model is to provide a kind of and be easy to carry for overcoming above-mentioned shortcoming, need not to install, and measures more accurate portable balance weighing apparatus.
The utility model is by the main arm beam of steelyard (1) that indicates weight scale and scale quantity and superincumbent restriction counterweight (3) is installed, non-exchange movable modular counterweight (2), handheld ring effect fulcrum (4) and (5), weight hook effect fulcrum (6), protection box (7), horizontal level tube (8) formed.The weight of movable modular counterweight (2) restriction counterweight (3), handheld ring effect fulcrum (4) and (5), weight hook effect fulcrum (6) or position are all according to the lever principle setting.Handheld ring effect fulcrum (4) with (5), weight hook effect fulcrum (6), all adopt the edge of a knife to contact and protect box (7) protection.Horizontal level tube (8) is parallel to the main arm beam of steelyard (1) and installs.
Owing to adopted technique scheme compared with the prior art, the utlity model has simple in structurely, easy to use, be easy to carry, measure advantages such as more accurate, increased usable range, measure and civilian metering in the field that can be widely used in research work.
Description of drawings:
Accompanying drawing 1 is the utility model concrete structure synoptic diagram (I of accompanying drawing 2-I orthogonal view).
Accompanying drawing 2 is vertical views of the present utility model.
Accompanying drawing 3 is II-II cut-open views of accompanying drawing 1.
Embodiment:
Accompanying drawing has been described an embodiment of the present utility model, referring to accompanying drawing: the utility model by the main arm beam of steelyard (1) that indicates weight scale and scale quantity and non-exchange movable modular counterweight (2), restriction counterweight (3), handheld ring effect fulcrum (4) and (5), weight hook effect fulcrum (6) located in the above, protect box (7), horizontal level tube (8) to form.It is square that the main arm beam of steelyard (1) is prolate, and in order to adjust itself center of gravity, it is wide that the main arm beam of steelyard (1) is made an end, and the other end is narrow slightly.And establish a restriction counterweight (3) on the top of a narrow end, restriction counterweight (3) unifies with the main arm beam of steelyard, to stop movable modular counterweight (2) the main arm beam of steelyard (1) that slips away, also plays the effect of adjusting the main arm beam of steelyard (1) center of gravity simultaneously.The flat master arm beam of steelyard (1) is provided with movable modular counterweight (2), presses P on the inherent flat master of the moving range arm beam of steelyard of standard test weight (2)
1L
2=P
2(L
2+ L) engrave scale, put on the weight number simultaneously in the relevant position.(P
1-metering thing weight, L
2-weight hook effect fulcrum is to the distance of handheld ring effect fulcrum, P
2-movable modular counterweight is heavy, L
2The distance that-standard test weight moves, L-counterweight arrive the distance of handheld ring effect fulcrum when zero position).The thicker end of the flat master arm beam of steelyard is provided with handheld ring effect fulcrum (4), (5) and weight hook effect fulcrum (6), they the position is set according to above-mentioned L
1, L
2, L and setting.Fulcrum adopts the contact of edge of a knife shape to improve precision of the present utility model and sensitivity.Handheld ring effect fulcrum (4), (5) and weight hook effect fulcrum (6) are protected with protection box (7); firm being fixed on the main arm beam of steelyard (1) of protection box (7); protection box (7) is provided with the rectangle slotted eye, to draw portable effect fulcrum ring and weight fulcrum hook.One end of the main arm beam of steelyard (1) is provided with rectangle four directions blind hole and establishes horizontal level tube (8) in its inside.
During use weight is suspended on the weight fulcrum hook, extracts portable fulcrum ring (4) or (5) mobile then counterweights (2) are horizontal the main arm beam of steelyard, read the pairing numerical value of counterweight (2) again and be weight of heavy according to weight of heavy.
Claims (4)
1, a kind of balance weighing apparatus; it is characterized in that adopting the main arm beam of steelyard (1) that indicates weight scale and scale quantity, be provided with non-exchange movable modular counterweight (2) and restriction counterweight (3), handheld ring effect fulcrum (4), (5), weight hook effect fulcrum (6), protection box (7), horizontal level tube (8) above it.
2, balance weighing apparatus according to claim 1 is characterized in that: restriction counterweight (3) is fixed on the tail end of the arm beam of steelyard (1), and handheld ring effect fulcrum (4), (5), weight hook effect fulcrum (6) are located at the other end of the arm beam of steelyard (1).Handheld ring effect fulcrum (4), (5) and weight hook effect fulcrum (6) protect box (7) upper shed also to draw handheld ring and the weight hook with protection box (7) protection that is fixed on the arm beam of steelyard (1).
3, balance weighing apparatus according to claim 1 is characterized in that: standard test weight (2) can move freely in the graduated scope of main arm beam of steelyard subscript but the main arm beam of steelyard (1) that can not slip away.
4, balance weighing apparatus according to claim 1 is characterized in that: horizontal level tube (8) can be located at any conspicuous position of the arm beam of steelyard.
