[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0023] like Figure 1-2A device for detecting the distortion of a steel structural member is shown, comprising a fastener for clamping an end of the structural member, a connecting rod with adjustable length connected to the fastener, a steering adjustment member mounted on the other end of the connecting rod, and a detecting member mounted on the steering adjustment member for contact with the surface of the structural member, wherein the detecting member maintains a perpendicular angle to the surface of the structural member, and the connecting rod maintains a parallel angle to the surface of the structural member;

[0024] Based on the above, when in use, the entire device is clamped at the end of the steel structure member through the fastener part. After clamping, the angle between the detection part and the fastener is adjusted by the steering adjustment part, and the distance between the detection part and the fastener is adjusted by the connecting rod part to move the detection part to the twisted part of the steel structure member. The distortion data is obtained by fitting the detection part to the twisted surface of the steel structure member.

[0025] The fastener includes a "C"-shaped clamping block, a rotatable clamping screw passing through one end of the clamping block, the end of the clamping screw extending to the inner side of the clamping block, a pressure block installed at the end of the clamping screw located on the inner side of the clamping block, and a knob installed at the other end of the clamping screw.

[0026] Based on the above, when in use, the clamping screw is rotated by turning the knob, driving the pressure block to move, so that the pressure block and the clamping block can act on the end of the steel structure to clamp and fix it.

[0027] The connecting rod comprises a prismatic sleeve mounted on the surface of the knob, a prismatic rod is inserted into the prismatic sleeve, and a concave first scale groove is formed on the surface of the prismatic rod;

[0028] The prismatic sleeve and prismatic rod are used so that the prismatic rod will not rotate and the angle will not change when it is telescoped and moved in the prismatic sleeve. The length parameter is engraved in the first scale groove, which is the distance data between the detection part and the pressure block. When the prismatic rod is telescoped and moved, the scale data will be revealed at the first scale groove and the prismatic sleeve.

[0029] The steering adjustment member includes a connecting block fixed to the end of the prismatic rod, a steering wheel is installed on the connecting block, the steering wheel is connected to a positioning plate, a positioning screw is passed through the connecting block, the end of the positioning screw is against the surface of the positioning plate, and the detection member is installed on the surface of the positioning plate away from the positioning screw.

[0030] Furthermore, when the knob is turned to drive the clamping screw to rotate, the angle between the prismatic sleeve, the prismatic rod, and the detection member and the clamping block will be changed. Therefore, after the fastener is clamped and fixed, the angle between the connecting block and the positioning plate is adjusted by the steering wheel to change the angle of the detection member on the positioning plate;

[0031] The detection member includes a shaft sleeve fixed on the side of the positioning plate away from the connecting block, a movable detection rod is inserted into the shaft sleeve, and a second scale groove is opened on the outer wall of the detection rod.

[0032] Based on the above, the prismatic rod and the detection rod are both provided with damping in the shaft sleeve and the prismatic sleeve to prevent the prismatic rod and the detection rod from shaking randomly during use, and an anti-falling structure is provided to prevent the prismatic rod and the detection rod from falling out of the shaft sleeve and the prismatic sleeve;

[0033] The second scale groove has a length parameter, which is the distance between the point where the end of the detection rod is located and the intersection point between the straight line where the detection rod is located and the straight line where the detection rod is located.

[0034] A through-hole for correction is provided at the end of the clamping block, a correction protrusion is installed on the inner wall of the clamping block, and a laser is installed at the bottom of the shaft sleeve, and the optical path of the laser is on the same straight line as the correction hole and the correction protrusion;

[0035] Furthermore, during use, the angle between the detection part and the fastener is kept fixed, and the laser is emitted by the laser, so that the laser passes through the correction hole and falls on the correction protrusion, so that the three are kept in the same straight line, and the angle between the detection part and the fastener is fixed without contact.

[0036] On the basis of the above, when in use, the device is fixedly installed on the end of the steel structure by fasteners, and after adjusting the angle and position using the connecting rod and the steering adjustment member, the detection rod is moved so that its end is against the twisted surface of the steel structure. The parameters in the second scale groove are used to obtain the distance between the twisted surface and the normal surface of the steel structure, and the two are calculated based on the parameters in the first scale groove to obtain the angle parameters between the twisted point and the surface of the steel structure, thereby completing the twist detection.

[0037] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
