[0037] As Figure 1 and Figure 2 shown, the adjustable magnetic pickup fixing structure of the present utility model is used to fasten the pickup 10 to the member to be detected. The fixing structure includes a binding band 21, a connecting buckle 22, a first magnetic member and a second magnetic member 23. The binding band 21 is detachably connected to the pickup 10, and the binding band 21 has a first end and a second end arranged oppositely. The connecting buckle 22 is arranged at the first end of the binding band 21, and a through hole is arranged on the connecting buckle 22. The first magnetic member is arranged at the second end of the binding band 21. The second magnetic member 23 is arranged on the binding band 21, and the second magnetic member 23 can be adsorbed to the first magnetic member. When fastening the pickup 10, the second end of the binding band 21 is passed through the through hole of the connecting buckle 22 and then pulled back tightly, and then the pickup 10 and the member to be detected are fastened through the adsorption and fixation of the first magnetic member and the second magnetic member 23.

[0038] Preferably, connection ports are arranged on both sides of the bottom plate of the pickup 10, and the second end of the binding band 21 passes through these two connection ports in sequence, realizing the detachable connection between the binding band 21 and the pickup 10. When installing the pickup 10, the bottom plate of the pickup 10 is attached to the member to be detected (such as a stay bar or a cable), and then the second end is wound around the outer circumference of the member to be detected and then inserted into the through hole of the connecting buckle 22, wound around a side wall at the through hole and then wound back in the opposite direction, and the second end is tightened, so that the binding band 21 can fasten the pickup 10 and the member to be detected. Then, the first magnetic member at the second end is attached to the second magnetic member 23 to realize adsorption and fixation.

[0039] Further, a part of the binding band 21 is attached to the vibration pickup 10, and the second magnetic attraction member is not provided on the part attached to the vibration pickup 10. Not providing the second magnetic attraction member on this part can avoid affecting the normal use function of the vibration pickup.

[0040] Still further, the connection buckle 22 is annular and has a through opening formed therein. The connection buckle 22 is preferably square or circular.

[0041] Also further, the first magnetic attraction member and the second magnetic attraction member 23 are adhered to the binding band 21. They can be fixedly adhered to the binding band 21 through an adhesive.

[0042] In another preferred embodiment, accommodation spaces are provided on the binding band 21 corresponding to the first magnetic attraction member and the second magnetic attraction member 23, and the first magnetic attraction member and the second magnetic attraction member 23 are embedded into the corresponding accommodation spaces.

[0043] Specifically, the binding band 21 can be a woven band formed by braiding cords. The woven band has a double-layer structure and an accommodation space is formed inside. Installation openings are provided on the inner side surface of the woven band. The first magnetic attraction member and the second magnetic attraction member can be loaded from the corresponding installation openings. The size of the installation openings can be designed to be smaller than the sizes of the first magnetic attraction member and the second magnetic attraction member, so that the first magnetic attraction member and the second magnetic attraction member are not easily detached from the installation openings. Or after the first magnetic attraction member and the second magnetic attraction member are loaded into the corresponding accommodation spaces, the installation openings are sewn up.

[0044] Further, the first magnetic attraction member can be provided on the inner side surface of the binding band 21, and the second magnetic attraction member can be provided on the outer side surface of the binding band 21.

[0045] In one embodiment, as Figure 2 shown, the first magnetic attraction member and the second magnetic attraction member 23 are magnetic blocks, and a plurality of second magnetic attraction members 23 are provided. The second magnetic attraction members 23 are arranged at intervals on the binding band 21.

When fastening the pickup, the other end of the second strap 25 is passed through the through hole of the connection buckle 22 and then pulled tight in the reverse direction, and then the pickup 10 is fastened to the test piece to be measured through the adsorption and fixation of the first magnetic member and the second magnetic member.

[0050] The difference between the second embodiment and the first embodiment is that in the second embodiment, two separate straps are used to be detachably connected to the corresponding side parts of the pickup 10 respectively.

[0051] Connection ports are arranged on both sides of the bottom plate of the pickup 10, and the first strap 24 and the second strap 25 are respectively connected to the corresponding connection ports. Specifically, the corresponding ends of the first strap 24 and the second strap 25 bypass the connection ports, and then the corresponding ends are attached to the strap body, and are fastened and fixed through the provided lock buckle 26. Before fixing the lock buckle 26, the length of the remaining part of the corresponding ends of the straps can be adjusted, and thus the lengths of the first strap 24 and the second strap 25 for bundling the test piece to be measured are adjusted. The lock buckle 26 can be opened and closed for adjustment, and a tooth-shaped structure is arranged on the docking surface of the lock buckle 26, which can bite and press the corresponding part of the strap.

[0052] In this way, the first strap 24 and the second strap 25 can adjust their own lengths according to the diameter of the test piece to be measured, and then the pickup 10 is bundled on the corresponding test piece to be measured.

[0053] The structures of the connection buckle 22, the first magnetic member and the second magnetic member in the second embodiment of the present utility model are the same as those in the first embodiment.
