Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an annular force-bearing flange spoke type sensor. Background Art

[0002] The spoke type sensor is a force sensor made of spoke type elastic body structure and shear stress principle. The spoke type tension and pressure sensor adopts cross shear beam structure and has the advantages of good linearity, strong anti-eccentric load capacity, high precision, low profile height, convenient and stable installation, etc.

[0003] When in use, most spoke-type sensors are currently connected by a middle thread and are stressed in the middle. Sometimes the tension and compression connecting rod is a hollow tube, which requires the connection and stress of the sensor to be different from the traditional ones. Therefore, a ring-shaped stress-bearing flange spoke-type sensor is proposed to solve the above-mentioned problems. Utility Model Content

Both the upper and lower flanges have connecting threaded holes. After being connected to the connecting rod, the force value is tested by pulling and pressing the flange. A strain gauge is arranged on the top of the elastomer. The base of the strain gauge is constantan material, which can make the pressure strain gauge stably used at room temperature and have good insulation, ductility and flexibility. It can be completely fitted to the strain part of the elastomer and has the best overall comprehensive performance. The sensor is pasted after applying insulating protective material, which improves the accuracy and reliability of sensor detection and avoids interference with readings. A sealing sheet is fixedly connected to the top of the flange. The sealing sheet is made of stainless steel and is coated with silicone. This silicone has a wide range of operating temperatures and can meet the operating environment requirements of the sensor from -°C to +°C, while meeting the requirements of protection grade IP.

[0009] Preferably, the protection mechanism includes a bidirectional threaded rod. The bidirectional threaded rod is rotatably connected to the left inner wall of the fixed box through a bearing. One end of the bidirectional threaded rod away from the left inner wall of the fixed box is fixedly connected to a rotating rod. One end of the rotating rod away from the bidirectional threaded rod is fixedly connected to a handle. The handle is provided for driving the rotating rod and the bidirectional threaded rod to rotate.

[0010] Preferably, a threaded sleeve is threadedly connected to the outer wall of the bidirectional threaded rod. A cross plate is fixedly connected to the left side of the threaded sleeve. A clamping block is fixedly connected to the front surface of the cross plate. A horizontal groove is formed inside the fixed box. The cross plate movably penetrates through the horizontal groove and extends outward. The bidirectional threaded rod is provided for driving the threaded sleeve to move. The bidirectional clamping block is used for protecting the cable to prevent the cable from loosening and affecting the use effect.

[0011] The utility model adopts the above technical solutions and can bring the following beneficial effects:

[0012] 1. For the annular force-bearing flange spoke-type sensor, through the cooperation among the elastomer, the sealing sheet, the aviation plug, and the cable, the pressure strain gauge can be stably used at normal temperature, and it has good insulation, ductility, and bendability. It can be completely attached to the strain part of the elastomer, with the best overall comprehensive performance. After applying the insulating protective material and then pasting the sensor, the accuracy and reliability of the sensor detection are improved, and the reading is prevented from being interfered.

[0013] 2. For the annular force-bearing flange spoke-type sensor, through the cooperation among the bidirectional threaded rod, the rotating rod, the handle, the threaded sleeve, the cross plate, the clamping block, and the horizontal groove, by clamping and protecting the cable with the clamping blocks on both sides, the situation of the cable loosening can be effectively avoided, so as not to affect the data transmission.
