DETAILED DESCRIPTION

[0021] The utility model will be described in further detail in connection with the drawings and preferred embodiments. These drawings are all simplified schematic diagrams and only schematically show the basic structure of the utility model, and thus only show the components related to the utility model.

[0022] Referring to Figure 1 - Figure 4 As shown in the figure, the utility model provides a technical scheme: a steel structure bolt detection device, including operation platform 1, the top of operation platform 1 is installed with pressure equipment 2, the top of operation platform 1 is installed with fixed seat 3, both sides of operation platform 1 are all set with moving groove 4, the inside of moving groove 4 is slidably connected with moving block 5, one side of moving block 5 is fixedly connected with protective plate 6, one end of protective plate 6 is fixedly connected with handle 7, one end of operation platform 1 is set with two plug-in slots 8, one end of handle 7 is set with movable slot 9, the inside of movable slot 9 is slidably connected with L-shaped rod 10, one end of L-shaped rod 10 is fixedly connected with plug-in rod 11, staff pulls handle 7, makes handle 7 drive protective plate 6 to move upwards, until moving to exceed the body, then pushes L-shaped rod 10, makes L-shaped rod 10 drive plug-in rod 11 to insert into the inside of plug-in slot 8 set in one end of operation platform 1, fixes the position of protective plate 6, so as to effectively block the fragments produced when the bolt is broken due to excessive force, prevent it from splashing the face and reduce the risk of failure or accident caused by bolt fracture.

[0023] Referring to Figure 3 In the embodiment, the material of protective plate 6 is high-strength engineering plastic, which has good impact resistance and can effectively absorb the energy generated when the bolt is broken, reducing the splashing range of fragments.

[0024] Referring to Figure 4 In the embodiment, one end of L-shaped rod 10 is fixedly connected with return spring 12, one end of return spring 12 is fixedly connected with the inside of movable slot 9, and return spring 12 can give L-shaped rod 10 a certain resilience, so that when the staff releases L-shaped rod 10, return spring 12 can drive plug-in rod 11 to quickly insert into the inside of plug-in slot 8 through its own elastic force, making the staff more efficient when using.

[0025] Referring to Figure 2 and Figure 4As shown, in the embodiment: the outer surface of the plug-in rod 11 is in sliding connection with the inner surface of the plug-in groove 8, and the outer surface of the plug-in rod 11 is in conformity with the inner surface of the plug-in groove 8. Due to the sliding connection and the conforming design between the plug-in rod 11 and the plug-in groove 8, the staff can more easily insert the plug-in rod 11 into the plug-in groove 8. When the plug-in rod 11 is fully inserted into the plug-in groove 8, a tight connection can be formed due to the conformity of the surfaces.

[0026] With reference to Figure 2 and Figure 3 As shown, in the embodiment: the two ends of the inner cavity of the moving groove 4 are provided with guide grooves 13, and the two ends of the moving block 5 are fixedly connected with guide blocks 14. The cooperation of the guide blocks 14 and the guide grooves 13 ensures the linear motion of the moving block 5 in the moving groove 4, thereby improving the stability and accuracy of the protective plate 6 during movement.

[0027] With reference to Figure 5 As shown, in the embodiment: one end of the guide block 14 is provided with a notch 15, the inside of the notch 15 is fixedly connected with a rotating shaft 16, the surface of the rotating shaft 16 is rotatably connected with a guide wheel 17. The arrangement of the guide wheel 17 can reduce the friction when the moving block 5 slides in the moving groove 4, thereby reducing the resistance during operation and improving the moving efficiency of the moving block 5.

[0028] With reference to Figure 3 As shown, in the embodiment: the bottom of the guide block 14 is fixedly connected with a tension spring 18, and the bottom of the tension spring 18 is fixedly connected with the bottom of the inner cavity of the moving groove 4. Through the elastic action of the tension spring 18, when the moving block 5 reciprocates in the moving groove 4, it can provide stable rebounding force, ensuring that the moving block 5 can quickly and accurately return to the initial position.

[0029] Working principle: the worker pulls the handle 7, the handle 7 drives the protective plate 6 to move upwards until it is beyond the body, then pushes the L-shaped rod 10, the L-shaped rod 10 drives the plug-in rod 11 to insert into the plug-in slot 8 at one end of the operation table 1, and the position of the protective plate 6 is fixed, so that the fragments generated when the bolt is broken due to excessive force can be effectively blocked, preventing them from splashing the face and reducing the risk of failure or accidents caused by bolt breakage. High-strength engineering plastics have good impact resistance and can effectively absorb the energy generated when the bolt breaks, reducing the splashing range of the fragments. The reset spring 12 provides a certain resilience to the L-shaped rod 10, so that when the worker releases the L-shaped rod 10, the reset spring 12 can drive the plug-in rod 11 to quickly insert into the plug-in slot 8, making the worker more efficient when using. Due to the sliding connection and matching design between the plug-in rod 11 and the plug-in slot 8, the worker can more easily insert the plug-in rod 11 into the plug-in slot 8. When the plug-in rod 11 is fully inserted into the plug-in slot 8, a tight connection can be formed due to the matching surfaces. The use of the guide block 14 and the guide slot 13 ensures the linear motion of the moving block 5 in the moving slot 4, thereby improving the stability and accuracy of the protective plate 6 during movement. The setting of the guide wheel 17 reduces the friction when the moving block 5 slides in the moving slot 4, thereby reducing the resistance during operation and improving the moving efficiency of the moving block 5. Through the elastic action of the tension spring 18, when the moving block 5 reciprocates in the moving slot 4, it can provide stable resilience to ensure that the moving block 5 can quickly and accurately return to the initial position.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
