Abstract
The utility model provides a compound force arm type portable steelyard, which is composed of a steelyard body, a steelyard rob, a counterweight, an added weight, an added weight knife, a steelyard lifting knife, a steelyard hook knife, a steelyard hook connecting frame, a steelyard lifting connecting frame, a steelyard hook, an added weight slide scale and a steelyard lift. The utility model adopts the compound type force arm structure, having novel structure, reasonable design, small size, adjustable weighing range and convenient operation and portability. The compound force arm type portable steelyard is a novel weighing appliance.
Description
The utility model belongs to a kind of weighing utensil, is that a kind of counterweight can be along the arm-type portable balance of the composite force that crossbeam moves particularly.
Mostly the scale that normally used counterweight moves along crossbeam is to be equipped with single arm of force formula scale of single sliding weight of steelyard as steelyard, pan scale.It by the arm beam of steelyard that is shaped on the weighing scale, sliding weight of steelyard, title carry, claim to griffe, steelyard hook cutter, steelyard hook knife rest and claim that hook or pan of a steelyard are formed.Because what adopt is single arm of force formula structure, the volume of its scale scope of greatly, correspondingly weighing is little, carries and use comparatively inconvenience.
The purpose of this utility model provides a kind of improved scale, and it is little to make it have a volume, novel structure, and correspondingly range of weighing is big, makes in carrying and using.
The utility model be achieved in that according to for its equilibrium condition of the object under the parallel force effect be exactly suffered each power make a concerted effort equal zero, these power are to all null principle of the resultant moment of any rotating shaft simultaneously, be designed to the arm-type scale of composite force of two sliding weight of steelyards, promptly adopt long square groove shape scale body, with the arm beam of steelyard together with sliding weight of steelyard and scale thereof griffe, the steelyard hook cutter is assemblied in the long recess of scale body, and at an end of scale body assembling increasing stone roller, other end connection increasing stone roller cutter, increase stone roller cutter connection scale and carry the connection frame, scale is carried connection frame connection scale and is griffed; Be equipped with in the notch of scale body and increase the stone roller slide sign, increase the stone roller slide sign and connect the arm beam of steelyard.Increase the stone roller slide sign by setting, make the arm beam of steelyard and title body and scale carry the connection frame and connect into turnover combined type arm structure, correspondingly increased the arm of force, dwindled volume, increased range of weighing, so the utility model not only volume is little, range of weighing is big, novel structure, and carry and use comparatively convenient.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
As shown in drawings, the utility model is by scale body 4, the arm beam of steelyard 3, sliding weight of steelyard 2, increase stone roller cutter 1, increase stone roller slide sign 5, increase stone roller 10, scale is carried connection frame 7, scale griffes 6, steelyard hook cutter 9, steelyard hook connection frame 11, steelyard hook 12 and scale are carried 8 compositions, scale body 4 is long square groove shape body, the arm beam of steelyard 3 is housed in the elongated slot of scale body 4 and claims stone roller 2, the intrinsic stone roller 10 that increases of the one end edge of scale body 4, the other end is shaped on and increases stone roller cutter 1, increase stone roller cutter 1 connection scale and carry connection frame 7, the scale that scale is carried on the other end connection arm beam of steelyard 3 that joins frame 7 griffes 6, on the notch of scale body 4, be shaped on to increase stone roller amount scale and be equipped with to increase and cut or polish jade with an emery wheel slide sign 5, increase stone roller slide sign 5 and connect the arm beams of steelyard 3.For the ease of using, carry on the connection frame 7 at scale and also to be shaped on balanced pointers 14 and horizontal ruler 13 is housed, and on scale body 4, cooperate and be shaped on balanced pointers carriage 15.
When the utility model uses, according to weigh, at first set up and increase the stone roller slide sign, will claim stone roller along arm beam of steelyard slip again, make balanced pointers, horizontal ruler balance, read the weighing scale, just finish and weigh.
The utility model shows through test for several times is on probation, its novel structure, reasonable in design, volume is little, carry with easy to use, is a kind of novel weighing utensil.
Claims (4)
1, the arm-type portable balance of a kind of composite force, it comprises that the arm beam of steelyard 3, sliding weight of steelyard 2, scale are griffed 6, claimed billhook 9, claim to be hooked together frame 11, steelyard hook 12 and scale carry 8, it is characterized in that this scale also comprise scale body 4, scale carry the connection frame 7, increase the stone roller cutter 1, increase the stone roller slide sign 5 and increase the stone roller 10, scale body 4 one ends edges is intrinsic to increase stone roller 10, the other end is shaped on and increases stone roller cutter 1, increasing stone roller cutter 1 connects scale and carries connection frame 7, scale and carry the other end of connection frame 7 and connect scale and griffe 6, on the notch of scale body 4, be equipped with to increase and cut or polish jade with an emery wheel slide sign 5, increase stone roller slide sign 5 and connect the arm beams of steelyard 3.
2, scale according to claim 1 is characterized in that scale body 4 is long square groove shape body, is shaped on the notch to increase stone roller amount scale.
3, scale according to claim 1 is characterized in that being shaped on balanced pointers 14 on the scale sports association frame 7, cooperates to be shaped on balanced pointers carriage 15 on scale body 4.
4, scale according to claim 3 is characterized in that on the scale sports association frame 7 horizontal ruler 13 being housed also.
