Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present utility model provides a technical solution: a multifunctional bolt detection tool, including a base 1, an outer limiting frame 2 is fixedly installed on the top of the base 1, a first fixing component 3 and a second fixing component 4 identical to the first fixing component 3 are movably clamped inside the outer limiting frame 2, an electric push rod 5 is fixedly installed on the side of the inner side of the outer limiting frame 2 away from the first fixing component 3, a pull rod 6 is movably installed inside the second fixing component 4, a fixing plate 7 is movably installed on the outer side of the pull rod 6, a tension sensor 8 is fixedly installed on the outer side of the fixing plate 7, and the electric push rod 5 is fixedly connected to the tension sensor 8;

[0025] The fixing component 1 includes an installation block 31. An operation groove 32 is formed on the outer side of the installation block 31. A through port 33 is formed inside the installation block 31. A lower support block 34 is arranged below the inside of the through port 33. A sliding groove 35 is formed at the top of the installation block 31. An upper clamping block 36 is movably installed inside the sliding groove 35. A top plate 37 located at the top of the sliding groove 35 is fixedly installed on the top of the installation block 31. A threaded rod 38 is movably installed inside the top plate 37. The threaded rod 38 is movably clamped on the top of the upper clamping block 36. A handle 39 is movably installed at the top of the threaded rod 38. Through the same setting of the fixing component 1 and the fixing component 2, after the nut is installed on the bolt, by clamping it in the through port 33 and making the bolt head or the nut located outside the lower support block 34 respectively, the handle 39 drives the threaded rod 38 to rotate to drive the upper clamping block 36 to move downward in the sliding groove 35 and clamp above the rod body part of the bolt. Thus, it can be fixed according to bolts of different diameters, improving flexibility and use convenience.

[0026] The sliding groove 35 corresponds to the position of the through port 33. The through port 33 penetrates through the sliding groove 35. Through the correspondence between the sliding groove 35 and the through port 33, the upper clamping block 36 can slide up and down in the sliding groove 35 to adjust its height inside the through port 33, so as to adjust the distance between it and the lower support block, thus adapting to bolts of different sizes and facilitating adjustment.

[0027] The upper clamping block 36 is movably clamped inside the sliding groove 35. The inner sides of both the upper clamping block 36 and the lower support block 34 are arc-shaped. By the arc-shaped inner sides of both the upper clamping block 36 and the lower support block 34, it is easier to clamp the bolt. The sides of the bolt head and the nut abut against the sides of the upper clamping block 36 and the lower support block 34, thus ensuring stable force during stretching.

[0028] The length of the threaded rod 38 is equal to that of the sliding groove 35, increasing the range of the threaded rod 38 driving the upper clamping block 36 to move up and down in the sliding groove 35 and improving the adjustment range.

[0029] Please refer to Figure 3 and Figure 5 , a limiting block 310 is fixedly connected to the side of the fixing component 1. The outer limiting frame 2 includes a frame body 21. A second guiding groove 23 and a first guiding groove 22 are respectively formed on the left and right sides inside the frame body 21. The fixing component 1 and the fixing component 2 are respectively clamped inside the first guiding groove 22 and the placing and taking groove 24. A placing and taking groove 24 is formed above the inner side of the second guiding groove 23. It can be used by clamping the fixing component 1 in it by using the limiting block 310 on its side. Similarly, the fixing component 2 can be used by clamping it in the second guiding groove 23. The outer opening of the first guiding groove 22 facilitates the disassembly of the fixing component 1. At the same time, through the setting of the placing and taking groove 24 above the second guiding groove 23, the fixing component 2 can be moved upward along the placing and taking groove 24 for disassembly, facilitating the maintenance of the fixing component 1 and the fixing component 2.

[0030] The size of the pick-and-place slot 24 is adapted to the size of the limit block 310, so as to lift and remove the second fixing component 4 upward from the pick-and-place slot 24, which is convenient for carrying out operations on it.

[0031] Please refer to Figure 2 , perforations adapted to the pull rod 6 are provided inside both the first fixing component 3 and the second fixing component 4. The pull rod 6 is provided with nuts and fixed inside the fixing plate 7. By fixing the pull rod 6 to the fixing plate 7 with nuts, the second fixing component 4 can be effectively connected together to ensure stability during pulling, and at the same time ensure the stable detection of the tensile force sensor 8. At the same time, the setting of the perforations also makes the installation and disassembly of the pull rod 6 simpler and faster, further improving the practicability and convenience of the device.

[0032] Working principle: During use, the nut is screwed onto the outer thread of the bolt, and the bolt is placed inside the first fixing component 3. The head or nut part of the bolt is located on the side of the operation slot 32, and the rod part of the bolt is clamped on the lower support block 34. Then, by rotating the handle 39, the threaded rod 38 is rotated to drive the upper clamping block 36 to move downward in the sliding slot 35 and clamp above the rod part of the bolt. Similarly, the head or nut part of the other side of the bolt is clamped inside the second fixing component 4 with the same setting as the first fixing component 3. By controlling the electric push rod 5 to pull the second fixing component 4 to move, the bolt is stretched. The magnitude of the tensile force is detected by the tensile force sensor 8 and displayed through the display, which is convenient for the staff to detect the tensile force. By simultaneously detecting whether the thread is opened as required and the meshing strength of the thread on the surface of the bolt, the detection efficiency of the staff is improved, and thus the applicability to bolts of different diameters can be improved;

[0033] Through the setting of the first guiding groove 22, the first fixing component 3 can be used by clamping it in the first guiding groove 22 with the limit block 310 on its side. Similarly, the second fixing component 4 can be used by clamping it in the second guiding groove 23. The outer opening of the first guiding groove 22 facilitates the disassembly of the first fixing component 3. At the same time, through the setting of the pick-and-place slot 24 above the second guiding groove 23, the second fixing component 4 can be disassembled by moving it upward along the pick-and-place slot 24, which is convenient for maintaining the first fixing component 3 and the second fixing component 4.

[0034] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
