Description
Technical Field
The invention relates to the field of sensors, in particular to a tension and pressure sensor.
Background
The pull pressure sensor is also called as resistance strain sensor, belonging to the weighing sensor series, and is a device for converting physical signal into measurable electric signal and outputting the signal. The tension and pressure sensor takes an elastic body as a medium, resistance of the tension and pressure sensor is changed by resistance stress sheets acting on two sides of the patch sensor through force, and the resistance is converted into an electric signal through a corresponding circuit, so that the following control is realized.
Disclosure of Invention
The invention aims to solve the technical problems that: the technical problem that weighing precision is influenced due to the fact that the weighing sensor in the prior art is caused by the defects of structural design is solved, and the problem that weighing precision is influenced due to the fact that the ground is uneven can be effectively solved.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a draw pressure sensor, includes elastomer and bulb, and the elastomer middle part is equipped with the resistance strain gauge, and resistance strain gauge upper and lower both sides are equipped with a strain tank respectively, and two strain tank size is the same opening on the contrary, and the elastomer is S type structure, the top and the bottom of elastomer are equipped with a holding chamber respectively, the holding intracavity is equipped with the bulb, the club is connected to the top of bulb, bulb and club structure as an organic whole, be equipped with the internal thread pipe on the club, the internal thread of club internal thread pipe and the external screw thread fixed connection on the club.
Preferably, the external thread pipe can fix the ball head through a ball rod.
Preferably, a buffer gasket is arranged in the accommodating cavity.
The tension and pressure sensor has the advantages that the structure is simple, the ball head can rotate in the accommodating cavity to a certain extent through the matching among the ball head, the ball rod and the internal threaded pipe, and the problem that the weighing precision is affected due to uneven ground is solved.

FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in figure 1, the tension and pressure sensor comprises an elastic body 1 and a ball head 2, wherein a resistance strain gauge 3 is arranged in the middle of the elastic body 1, a strain groove 4 is respectively arranged on the upper side and the lower side of the resistance strain gauge 3, the two strain grooves 4 are the same in size and have opposite openings, the elastic body is of an S-shaped structure, an accommodating cavity 5 is respectively arranged at the top and the bottom of the elastic body 1, the ball head is arranged in the accommodating cavity 5, a certain gap is formed between the accommodating cavity 5 and the ball head 2, the ball head 2 can rotate in the accommodating cavity 5 to a certain degree, a buffer gasket 8 is arranged in the accommodating cavity 5 to protect tension measurement of the sensor to a certain degree, the ball head 6 is connected above the ball head 2, the ball head 2 and the ball head 6 are of an integral structure, an internal thread pipe 7 is arranged on the ball head 6, and an internal thread in the, thereby realize fixed bulb 2, prevent that bulb 2 from rotating, make the pulling force measurement more sensitive, through the cooperation between bulb 2, club 6 and the internal thread pipe 7, bulb 2 can certain extent scope rotate in holding chamber 5 to solved and lead to weighing the problem that the precision is influenced because of the ground is uneven.
When carrying out pressure measurement, the pressure that receives transmits bulb 2, and the bulb 2 atress is concentrated, buffer pad 8 in the holding chamber 5 protects bulb 2, on bulb 2 can transmit the not equidirectional power to elastomer 1, elastomer 1 stress takes place to deform, and the resistance that resistance should piece 3 changes, and the resistance converts digital signal output.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
