Abstract
The invention relates to a weighting apparatus that includes jar canister, plunger, capping, connecting rod, bearing disc, gas, ruler, and pointer. The jar canister and plunger are matching tightly and could relatively slide. Gas is filled between the jar canister and plunger. The heavy could be lay on the bearing disc and transfer the weight to the plunger to decrease the volume of the gas that could transform to the alteration of weight. Reading the weight value through pointer and ruler, the purpose would be achieved.
Description
Technical field
The present invention relates to the weighing apparatus field, especially refer to a kind of weighing apparatus device that utilizes the gas contraction principle to carry out weighing.
Background technology
Weighing apparatus is one of people's productive life equipment commonly used.Comprise mechanical weighing apparatus and electronic scale etc., mechanical weighing apparatus wherein is to utilize lever displacement principle or elastic principle, and electronic scale is to utilize the sensor measurement principle, and main the application comprises: steelyard, platform balance, truck scale, track scale etc.The utility model patent of existing one " hydraulic weighing apparatus " by name, its patent No. is 98216153, it comprises bearing plate, hydraulic prop, it is characterized in that: the below of bearing plate is evenly distributed with 4～12 hydraulic props, and the fluid cylinder of each hydraulic prop all is connected by the fluid cylinder of the less hydraulic prop of oil guide pipe and piston cross-section.The piston of the hydraulic prop that these piston cross-sections are less all withstands on the measuring mechanism of making a concerted effort, and the measuring mechanism of should making a concerted effort can be an electronic scales that a plurality of pressure transducers are arranged.This utility model structure is simple relatively, Installation and Debugging are convenient, cost is lower, highly sensitive.
Though the more traditional weighing apparatus of above-mentioned hydraulic weighing apparatus has been done many improvement, structurally simple not enough, also inconvenient do very little of volume, and comprise a plurality of pressure transducers, so cost still is higher.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of weighing apparatus that utilizes gaseous tension to weigh at above-mentioned prior art present situation, has that structure is more simple, volume is more small and exquisite, cost is more cheap, and is reliable for effect, the characteristics that the scope of weighing is bigger.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: 1, select the piston and the cylinder device that closely cooperate and can be free to slide relatively for use, charge into nitrogen or other inert gases in the cylinder barrel, gravity can make gas volume diminish when weighing, and gaseous tension increase simultaneously can support external force; 2, can place above the supporting disk and treat the weighing weight, and by connecting rod weight transfer to piston, pressure gas changes its volume; 3, with the increase of weight weight, relative displacement takes place between connecting rod and the cylinder barrel in diminishing of the volume of gas, the variation of displacement is adjusted the weight numerical value that just can read object for the variation of weight.
As improvement, described weighing apparatus is to select piston and the cylinder device that is sealed and matched and can slides relatively freely for use, inner filling nitrogen or other inert gases, wait to claim that the gravity of object passes to piston by load-bearing plate and connecting rod, utilize the gas principle that volume reduces under external force, pressure increases, the gas volume changing value is converted into the Gravity changer value, can reaches the purpose that object is weighed.
As improving, piston that the present invention is used and cylinder barrel cross sectional shape can be circular, oval or other shapes again, and cylinder barrel, connecting rod and load-bearing plate can be that integral type also can be split type.
As improving, it is that length by limiting rod realizes that the present invention limits range of weighing, promptly reaches the weighing limit when load-bearing plate props up gland, thereby plays the self-protection effect again.
As further improvement, scale and pointer can be separately fixed at cylinder barrel and load-bearing plate (or connecting rod) side, and can adjust among a small circle to adapt to the weighing precision of different air pressure and gravitation area and temperature difference larger area.
Compared with prior art, the present invention utilizes the variation of gas volume and pressure to come the weighing object, intuitively reading numerical values.The invention has the advantages that like this, at first simplify the structure, no longer need electronic sensor and display system, cost of manufacture also reduces greatly; Next is that the design's structure can improve the scope of weighing greatly and can carry out self-protection to structural safety.Therefore the present invention is a kind of very practical design, is worthy of popularization.
Description of drawings
Fig. 1 is the structure schematic appearance of the embodiment of the invention;
Fig. 2 is the sectional view of Fig. 1;
The synoptic diagram of Fig. 3 during for practical application of the present invention;
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.As Fig. 1, Fig. 2, shown in Figure 3, cylinder barrel (1), piston (2), gland (3), connecting rod (4), load-bearing plate (5), gas (6), screw (7), scale (8) and pointer (9) have been the present invention includes.Wherein piston (2), connecting rod (4) and load-bearing plate (5) can be that one also can split be passed through mechanical connection, and under no-load condition, this weighing apparatus remains static, and total indicator reading is 0.When weight (10) being placed load-bearing plate (5) go up, under the effect of gravity, the gas compression, piston (2), connecting rod (4), load-bearing plate (5) and pointer (9) move down, and reach a new equilibrium state, and at this moment the reading of pointed is exactly the weight of object.
Owing to can produce certain friction force inevitably between piston and cylinder barrel, influence weighing precision within the specific limits, so the present invention is more suitable in weighing greater weight object, such as being used for truck scale, track scale etc.Under the situation that sealing property allows, inert gas can carry infinitely-great gravity in theory, and therefore the scope of weighing of the present invention depends on the sealing property between piston and the cylinder barrel.Its scope restriction of weighing can realize promptly when load-bearing plate props up gland, promptly reach the weighing limit, and still having certain space in the cylinder barrel this moment, thereby play the self-protection effect by limiting rod length less than the cylinder barrel degree of depth.
Claims (6)
