Abstract
The utility model relates to a novel tension sensor, it is bilateral symmetry and sets up, the light guide plate comprises a substrate. A through -hole has been seted up in the central authorities of base plate, the four corners of through -hole is equipped with a breach, breach and through -hole intercommunication respectively, four metal strain gauge are posted to the side of base plate, metal strain gauge is located the outside of each breach. The utility model discloses a novel tension sensor simple structure, processing is convenient, and is with low costs, and measurement accuracy is high, and how many it can measure and restrain to tension of a few hectogram power, is particularly suitable for yarn tension's measurement.
Description
[technical field]
This utility model relates to a kind of sensor, is specifically related to a kind of novel tension pick-up, belongs to sensor technical field.
[background technology]
At present, market has some tension measuring devices to use elastomer and the scheme of strain resistor dynamometry, but being substantially the field applied truck is weighed or other bigger external force is measured, its precision is poor, it is not particularly suited for this kind of several grams of measurements to the tension force of hundreds of gram force of yarn tension.
Therefore, for solving above-mentioned technical problem, the elastic metallic body of a kind of innovation of necessary offer and there is the tension pick-up of elastic metallic body, to overcome described defect of the prior art.
[utility model content]
For solving the problems referred to above, the purpose of this utility model is to provide a kind of simple in construction, and easy to process, certainty of measurement is high, and the novel tension pick-up of stable performance.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of novel tension pick-up, and its symmetrical setting, including a substrate；A through hole is offered in the central authorities of described substrate；The corner of described through hole is respectively equipped with a breach, and breach connects with through hole；Four metal strain plates are posted in the side of described substrate, and described metal strain plate is positioned at the outside of each breach.
Novel tension pick-up of the present utility model is further arranged to: described breach semicircular in shape.
Novel tension pick-up of the present utility model is further arranged to: two breach one full circle of composition being oppositely arranged.
Novel tension pick-up of the present utility model is further arranged to: described substrate is integral type structure, and it is strip；Described metal strain plate is positioned on the long limit of substrate.
Novel tension pick-up of the present utility model is also configured to: described substrate is provided with installing hole.
Compared with prior art, this utility model has the advantages that novel tension pick-up simple in construction of the present utility model, easy to process, low cost, and certainty of measurement is high, its can measure several grams to the tension force of hundreds of gram force, be particularly suitable for the measurement of yarn tension.

Fig. 1 is the structural representation of novel tension pick-up the first embodiment of the present utility model.
Fig. 2 is the structural representation of novel tension pick-up the second embodiment of the present utility model.
[detailed description of the invention]
Referring to shown in Figure of description 1, it is the first embodiment of novel tension pick-up of the present utility model, its symmetrical setting, including a substrate 1.
A through hole 2 is offered in the central authorities of described substrate 1.The corner of described through hole 2 is respectively equipped with a breach 3, and breach 3 connects with through hole 2.In the present embodiment, described breach 3 semicircular in shape.
Four metal strain plates 4 are posted in the side of described substrate 1, and described metal strain plate 4 is positioned at the outside of each breach 3.
Further, described substrate 1 is integral type structure, and it is strip.Described metal strain plate 4 is positioned on the long limit of substrate 1.Described substrate 1 is provided with installing hole 5, in order to install this tension pick-up.
The operation principle of novel tension pick-up of the present utility model is as follows: testee presses on substrate 1, and power acts on tetra-positions of A, B, C, D.Metal strain plate 4 all it is pasted with in tetra-positions of A, B, C, D.Owing to the structure of novel tension pick-up is symmetrical, therefore, the deformation of A with C is identical, and the deformation of B with D is identical.Corresponding: the resistance value (calling Rac in the following text) of two positions of A, C changes identical, the resistance value (calling Rbd in the following text) of two positions of B, D changes identical.But the change of Rbd will be greater than Rac.The difference (calling △ R=Rbd Rac in the following text) of resistance variations is relevant with the size of tension force, it may be assumed that when tension force is O, △ R=O, along with the increase of tension force, △ R also will increase accordingly.The strain resistor of above tetra-positions of A, B, C, D is formed Wheatstone bridge, and the change of tension force just accurately can be measured by the change of △ R.
Referring to shown in Figure of description 2, it is the second embodiment of novel tension pick-up of the present utility model, and it is with the difference of the first embodiment: its two breach 3 being oppositely arranged form a full circle.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, all any modification, equivalent substitution and improvement etc. done within this spirit created and principle, within should be included in the protection domain of this creation.
