Description
Technical Field
The utility model relates to a pressure sensor elastomer especially relates to a clamp formula pressure sensor elastomer with two seal grooves, belongs to sensor technical field.
Background
The sputtering film pressure sensor is a pressure sensor with excellent performance, has the advantages of high precision, good stability, high temperature of a measured medium and the like, and is applied to a plurality of fields of aviation, aerospace, military industry, electric power, nuclear industry, petrifaction, traffic, metallurgy, food, medicine, internet of things and the like.
However, the elastomer and the pressure guiding nozzle of the sputtering film pressure sensor are split, and need to be welded after being processed respectively, and due to the welding equipment, process and other reasons, the leakage problem often exists, or the sensitive circuit on the elastomer is broken or the performance is poor after the test is carried out after the welding, and the product requirements cannot be met. Therefore, the waste can be discarded completely, which causes the reduction of production benefit and the increase of production cost.
Therefore, it is extremely important to develop a snap-fit type pressure sensor elastic body which does not require welding, is easy to install, and is easy to produce.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a do not need welded formula pressure sensor elastomer that clamps, to prior art's not enough, solve low, the high scheduling problem of production efficiency.
For solving the above technical problem, the technical scheme of the utility model is that: a clamping type pressure sensor elastomer is characterized in that: the clamping type pressure sensor elastic body is a cylindrical elastic body made of a metal material, the upper end of the clamping type pressure sensor elastic body is an elastic surface, the lower end of the clamping type pressure sensor elastic body is a hexagonal platform, and an opening at the lower end of the clamping type pressure sensor elastic body is upwards provided with a pressure introducing cavity for introducing pressure; two first sealing grooves and two second sealing grooves which can be provided with O-shaped sealing rings are continuously designed upwards in the hexagonal platform; and a stress release groove convenient for stress isolation is designed below the elastic surface.
The elastic surface can be manufactured with a strain resistor to form a detection circuit, and when pressure is introduced into the elastic surface through the pressure introduction cavity and acts on the elastic surface, the detection circuit outputs an electric signal corresponding to the pressure.
Compared with the prior art, the utility model discloses the beneficial effect who has does: on the premise of not influencing the performance of the elastomer, the conventional elastomer is designed with a clamping mode with a sealing groove, the elastomer is easy to install and produce, and the problems of high cost and low production efficiency caused by poor welding and the like due to welding equipment, processes and the like are solved.

Detailed Description
As shown in fig. 1 and 2, the elastic body of the snap-fit pressure sensor is a cylindrical elastic body made of a metal material, the upper end of the elastic body is an elastic surface 1, a strain resistor can be manufactured on the elastic surface 1 to form a detection circuit, and when pressure is introduced through the pressure introduction cavity 3 and acts on the elastic surface 1, the detection circuit outputs an electric signal corresponding to the pressure.
The lower end of the clamping type pressure sensor elastic body is a hexagonal platform 2, when the clamping type pressure sensor elastic body is arranged in an elastic body assembling cavity 8 in a pressure guide nozzle 7, a tool is pressed against the hexagonal platform 2, and the clamping type pressure sensor elastic body can be installed by forcibly pressing the tool into the elastic body assembling cavity 8.
The hexagonal platform 2 is continuously provided with a first sealing groove 3 and a second sealing groove 4 which can be provided with O-shaped sealing rings. The first sealing ring 31 is arranged in the first sealing groove 3, and the second sealing ring 41 is arranged in the second sealing groove 4, so that an effective sealing effect can be achieved.
And a stress relief groove 5 convenient for stress isolation is designed below the elastic surface 1. When the pressure leading nozzle 7 is fixed on the mounting seat through the connecting thread 9, the strain resistance performance on the elastic surface 1 cannot be influenced due to fastening stress, and the stability and the reliability of the sensor are ensured.
The opening of the lower end of the elastic body of the clamping type pressure sensor is upwards processed with a pressure guide cavity 6 for introducing pressure, when the pressure is introduced through the pressure guide cavity 6, the strain resistance on the elastic surface 1 is changed, an electric signal in direct proportion to the received pressure is output, and the accurate measurement of the pressure is realized.
Because the elastomer is provided with the two sealing grooves, the elastomer is easy to install, produce and assemble, and the problems of high cost and low production efficiency caused by infirm welding and the like due to welding equipment, processes and the like are solved.
The above description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention, and the claimed invention is not limited thereto, and all the equivalent variations that can be easily conceived by those skilled in the art according to the technical contents disclosed in the present invention should fall within the protection scope of the present invention.
