[0044] like Figure 1 As shown, a sensor installation and clamping device is provided, which is composed of a clamping mechanism 1 and a rotating fixing mechanism 2.

[0045] As shown in Figure 2, Figure 4~Figure 8As shown, the clamping mechanism 1 is mainly composed of: a fixed bracket 11, a screw 12, a square nut 13, a moving block 14, a first slotted screw 15, and a screw nut 16; the screw 12 passes through the first hole 111 and the second hole 112 on the fixed bracket, and is coaxial with the two holes, the first hole 111 and the screw shaft surface 122 are kept in clearance fit, the screw shaft end surface 123 is in contact with the outer end surface 115 of the fixed bracket, and cooperates with the connection between the screw nut 16 and the screw end thread 121 to ensure the axial fixation of the screw 12. The screw 12 and the square nut 13 are connected by rectangular threads for easy transmission. The upper end of the square nut 13 is provided with a threaded hole 131, which can be used in conjunction with the first slotted screw 15 to fasten the moving block 14 by threaded connection. After fastening, the front end face 141 of the moving block and the front end face 132 of the square nut remain in the same plane, which is conducive to enhancing the clamping stability. The bottom surface 142 of the moving block slides along the contact surface 116 on the fixed bracket, and the two side surfaces 133 of the square nut slide along the lower end groove 114 of the fixed bracket, which ensures the straightness of the reciprocating motion between the moving block 14 and the fixed bracket 11 when the screw rod 12 is rotated, and also plays a role in radially fixing the screw rod 12, thereby improving the transmission accuracy of the clamping mechanism 1. The screw head end 124 adopts a square head design for easy twisting.

[0046] like Figure 3 , Figure 9~Figure 12As shown, the rotating fixing mechanism 2 is composed of a rotating connecting plate 21, a rotating locking wheel 22, a threaded locking ring 23, an elastic locking member 24, a mounting plate 25, and a second slotted screw 26; the cylindrical body 212 at the lower end of the rotating connecting plate passes through the rotating locking wheel 22, the threaded locking ring 23, and the elastic locking member 24, and is coaxial, and the cylindrical body 212 at the lower end of the rotating connecting plate is provided with a threaded hole 2121, which can be threadedly matched with the second slotted screw 26 and pass through the hole 252 at the bottom of the mounting plate to ensure axial fixation with the mounting plate 25. The rotating locking wheel 22 and the elastic locking member 24 are in axial contact with the upper and lower end surfaces of the rotating connecting plate 21 and the mounting plate 25, so they remain fixed in the axial direction. The rotating locking wheel 22 and the threaded locking ring 23 adopt a trapezoidal thread for threaded matching, that is, rotating the rotating locking wheel 22 will cause the threaded locking ring 23 to produce axial relative movement. The outer ring part 241 of the elastic locking member is a wedge-shaped structure with a narrow top and a wide bottom, and the inner ring part 231 of the threaded locking ring is a wedge-shaped structure with a wide top and a narrow bottom. The axial movement of the threaded locking ring 23 can make the two contact or disengage. Since the elastic locking member 24 is made of elastic material, and there is a key protrusion 242 at the lower end of the elastic locking member, which cooperates with the key groove 253 on the mounting plate, the elastic locking member 24 cannot rotate axially relative to the mounting plate 25. When the threaded locking ring 23 contacts and squeezes, the locking member 24 will be deformed, squeezing the cylindrical body 212 at the lower end of the rotating connecting plate, increasing friction and making it impossible to rotate. When disengaging, the squeezing disappears, the deformation is restored, the friction is reduced, and the rotation can continue. There is an anti-skid groove 221 on the rotating locking wheel 22 to facilitate force. The upper radial end surface 222 of the rotating locking wheel and the upper end hole surface 213 of the rotating connecting plate are clearance-fitted.

[0047] The clamping mechanism 1 and the rotating fixing mechanism 2 can be connected and fixed by the fixing bracket 11 and the rotating connecting plate 21 through the threaded hole 211, and the mounting slot hole 251 on the mounting plate can be connected and fixed with the hole of the mounted surface.

[0048] The sensor mounting clamp works as follows:

[0049] Pre-process threaded holes on the surface of the installation object, and use screws, gaskets and installation slots 251 to fix the sensor installation clamping device on the surface of the installation object. Rotate the locking wheel 22 to loosen it, rotate the sensor installation clamping device to a suitable angle, rotate the locking wheel 22 to lock it, rotate the screw 12, adjust the clamping mechanism to clamp the sensor, and complete the position and angle fixation of the sensor on the surface of the installation object.

[0050] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
