Detailed Description
With reference to fig. 1 to 3, the present invention provides a cylindrical S-shaped sensor, which includes a cylindrical elastic body 1, a step 2 is disposed on an outer wall of the cylindrical elastic body 1, and a cylindrical shell 3 is disposed on the step 2; the middle part of the cylinder wall of the cylindrical elastic body is provided with four vertical S-shaped strain beams 4, the four S-shaped strain beams are sequentially connected to form a frame shape, and the directions of two adjacent S-shaped strain beams are opposite; the S-shaped strain beam can be obtained by forming the horizontal grooves 5 in the cylindrical wall of the cylindrical elastic body, and four horizontal grooves 5 may be provided. A strain gauge 6 is adhered to the beam surface of each S-shaped strain beam; the inner wall of the cylinder shell 3 is provided with a wiring terminal 7, and the side wall of the cylinder shell 3 is also provided with a cable joint 8; the four strain gauges are connected to the wiring terminal 7 through lead wires 9 to form a detection bridge; the connecting terminal 7 is also connected with the cable joint 8 to realize signal transmission. Preferably, the bending part of each S-shaped strain beam is provided with a circular arc chamfer 10.
When the device is used, the load of the annular surface at the upper end of the cylindrical elastic body 1 is transferred to the S-shaped strain beam, and the S-shaped strain beam works in a shear mode, so that the device has the lateral load resisting capability and can obtain the output characteristic which is not influenced by various adverse factors. The strain sensing and signal conversion are completed by a detection bridge consisting of strain gauges, and the signal transmission is performed by the cable joint 8. The utility model discloses both kept the stability that the cylinder annular distributes, eliminated the flexible shortcoming that easily receives complicated operating mode influence of section of thick bamboo wall again, installation convenient to use is swift.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments according to the invention, and may be used in various other applications, including, but not limited to, industrial. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.
