[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0041] like Figures 1-5 As shown, this embodiment provides a single-column housing for easy disassembly and assembly of a ferromagnetic inspection device. It is elongated and includes a rectangular shell 10, a base plate 20, and two rectangular caps 40. (See diagram below.) Figure 2 , Figure 5 As shown, both ends of the rectangular shell 10 are first openings 11, and U-shaped grooves 12 are formed in both end walls of the rectangular shell 10. Ear plates 21 are fixed to both sides of the base plate 20, and a bracket 30 is fixed to the sealed end wall of the base plate 20. The base plate 20 is a first U-shaped plate, and is inserted into the rectangular shell 10. The sensor 1 is mounted on the base plate 20. The sensor 1 uses existing technology, so it will not be described in detail. A Hall effect sensor 1, a magnetoresistive sensor 1, or a coil sensor can be selected. A through groove 13 is formed in the bottom wall of the rectangular shell 10 along its length, and the flared end of the first U-shaped plate faces the through groove 13. Two ear plates 21 are respectively mounted on the bottom wall of the rectangular shell 10, and the tops of multiple brackets 30 abut against the inner top wall of the rectangular shell 10. Multiple brackets 30 are arranged along the length of the rectangular shell 10, and each bracket 30 includes two third U-shaped plates 31. Two third U-shaped plates 31 are arranged along the width direction of the rectangular shell 10. Each third U-shaped plate 31 has a mounting plate 32 fixed at both ends. The mounting plate 32 is fixedly connected to the sealed end of the first U-shaped plate, and the sealed end of the third U-shaped plate 31 abuts against the inner top wall of the rectangular shell 10. Two rectangular caps 40 are respectively inserted at both ends of the rectangular shell 10. A second U-shaped plate 41 is fixed to the open end wall of each rectangular cap 40. The second U-shaped plate 41 is inserted into the U-shaped groove 12, and the two correspond one-to-one. Figure 4As shown, each rectangular cap 40 has a first threaded hole (not shown), and a first bolt 43 is screwed into the first threaded hole. The first bolt 43 can abut against the base plate 20. The bottom wall of each rectangular cap 40 has a recess 44, and the first threaded hole is located on the bottom wall of the recess 44. The first bolt 43 abuts against the base plate 20, so that the cap of the first bolt 43 is located inside the recess 44. The recess 44 is designed to embed the bolt cap, avoiding direct exposure, reducing the risk of bolt loosening due to external force interference, and improving long-term reliability. The first bolt 43 is a wing-shaped first bolt 43. The first bolt 43 is easy to tighten.

[0042] The ferromagnetic sensor 1 is fixed to the base plate 20. Then, the base plate 20, with its ear plates 21 and brackets 30, is inserted into the rectangular shell 10 through the opening at the bottom. The ear plates 21 fit against the inner side of the bottom wall of the rectangular shell 10, providing bottom support. Simultaneously, the top of the brackets 30 abuts tightly against the inner top wall of the rectangular shell 10, forming a stable support structure to prevent the base plate 20 from shaking. Two rectangular caps 40 are inserted from both ends of the rectangular shell 10, ensuring that the second U-shaped plates 41 on the rectangular caps 40 are precisely aligned and inserted into the U-shaped grooves 12 at the ends of the rectangular shell 10, completing the initial positioning. Finally, the first bolt 43 is screwed into the first threaded hole of the rectangular cap 40 and gradually tightened until the bolt end abuts tightly against the side wall of the base plate 20, ensuring the rectangular cap 40 is axially fixed and preventing it from loosening or falling off during long-term use. This structural design allows for rapid assembly of the outer shell, further reducing labor costs.

[0043] like Figure 1 , Figure 2 As shown, the top wall of the rectangular shell 10 has multiple straight slots 14 along its length, and a light strip 2 is installed on each straight slot 14. The light strip 2 adopts existing technology, so it will not be described in detail.

[0044] like Figure 3As shown, the single-column housing facilitates the disassembly and assembly of the ferromagnetic inspection device and also includes a mounting mechanism 50. Multiple mounting mechanisms 50 are arranged along the length of the rectangular housing 10, and are located within the rectangular housing 10 and the base plate 20. Each mounting mechanism 50 includes a rotating base 51 and a frame 52. The rotating base 51 includes a first flange 510, a first ring 511, a second ring 512, and multiple second bolts 513. The diameter of the inner ring of the second ring 512 is smaller than the diameter of the inner ring of the first ring 511. The multiple second bolts 513 are circumferentially arranged on the second ring 512, and the second bolts 513 sequentially pass through the second ring 512, the first ring 511, the first flange 510, and the sealing end wall of the base plate 20, where a nut (not shown) is screwed in. The inner ring of the first ring 511 forms an annular groove 514, which is embedded in a rotating disk 515. The frame 52 is fixed on the rotating disk 515, and the sensor 1 is mounted on the frame 52. The second ring 512 has a second threaded hole (not shown) along its axial direction. A third bolt 516 is screwed into the second threaded hole, and the third bolt 516 abuts against the rotating disk 515. The frame 52 includes a connecting rod 520, a horizontal tube 521, and an L-shaped plate 522. One end of the connecting rod 520 is coaxially connected to the rotating disk 515, and the other end of the connecting rod 520 is fixedly connected to the annular wall of the horizontal tube 521. A shaft 523 is rotatably arranged inside the horizontal tube 521, and a third threaded hole 5210 is opened in the horizontal tube 521. A fourth bolt 524 is screwed into the third threaded hole 5210. The fourth bolt 524 can abut against the shaft 523. One end of the shaft 523 is fixedly connected to one end of the L-shaped plate 522, and a sensor 1 is fixedly mounted on the other end of the L-shaped plate 522.

[0045] Align the first flange 510, the first ring body 511, and the second ring body 512 sequentially. Pass multiple second bolts 513 through the sealing end walls of the second ring body 512, the first ring body 511, the first flange 510, and the base plate 20, and tighten them with nuts. Embed the rotating disk 515 into the annular groove 514 of the first ring body 511, allowing it to rotate freely along the groove. Screw in the third bolt 516 through the second threaded hole on the second ring body 512, tighten it, and abut it against the side wall of the rotating disk 515 to lock the rotation angle. This forms a 360-degree rotation adjustment for the sensor. Fix one end of the connecting rod 520 coaxially with the rotating disk 515, and weld the other end to a horizontal tube 521. Insert a shaft 523 into the horizontal tube 521, allowing it to rotate freely, and connect the sensor 1 through an L-shaped plate 522. Loosen the fourth bolt 524 on the horizontal tube 521 and manually adjust the tilt angle of the shaft 523 and the L-shaped plate 522 to align the sensor 1 with the detection area.

[0046] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
