Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example (b):

referring to fig. 1 to 9, the acceleration sensor fixing device for mounting on a cylindrical bracket provided in this embodiment includes a movable cavity 1, a pressing sheet 2, a fixing disk 3, and an adjusting buckle 4.

As shown in fig. 1-2, the movable cavity 1 is mainly used for placing the acceleration sensor 100, and fixing the acceleration sensor 100 on a measuring point of the circular support 200 of the device, and the specific structure of the movable cavity 1 is as follows: one side of the movable cavity 1 is provided with an opening 11 which is used as a wiring 101 position of the acceleration sensor; the bottom end of the movable cavity 1 extends outwards to form two clamping parts 12, and the two clamping parts 12 are arranged oppositely; circular ring bulges 13 are distributed on the inner wall of the movable cavity 1 at intervals.

As shown in fig. 3, the compressing plate 2 is installed in match with the annular protrusion 13 in the movable cavity 1, when the acceleration sensor 100 is placed in the movable cavity 1, the acceleration sensor 100 is compressed and sealed in the movable cavity 1, so that the acceleration sensor does not slide up and down, sensors with different heights can be placed, and only the position of the compressing plate 2 needs to be adjusted.

As shown in fig. 4-5, the fixed disk belt 3 includes a fixed disk 31, and connecting belts 32 are connected and mounted on two opposite sides of the fixed disk 31; this fixed disk 31 is the cavity of upwards raising, the inner wall of this cavity is provided with two open slots 311, two open slots 311 are relative and establish, the bottom of this cavity inner wall is for having annular groove 312, the notch shape of this open slot 311 and annular groove 312 all with this joint portion 12 looks adaptation, so, when movable cavity puts 1 and arranges in fixed disk 31 and installs, aim at two open slots 311 with two joint portions 12, then rotate movable cavity 1, make joint portion 12 card steady in annular groove 312, if need change sensor 100 or take off sensor 100 only need with movable cavity 1's joint portion 12 rotate again to aim at the open slot 311 on the fixed disk, rotatory movable cavity 1 takes off can, thereby convenient replacement to failure sensor can not influence the fixed effect and the result of use of sensor.
