Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1

[0033] Reference Figure 1-Figure 6 The present invention provides a bracket-free acoustic emission sensor auxiliary fixing device, comprising a plurality of shells 5, a through slot 6 is provided on the outer wall of the shell 5, connecting parts are symmetrically arranged on both sides of the through slot 6, two connecting parts on opposite sides of two adjacent shells 5 are connected by a connecting piece 9, the connecting part is rotatably connected to the outer wall of the shell 5, a rotating bolt 1 is threadedly connected to the top surface of the shell 5, one end of the rotating bolt 1 extending into the shell 5 is rotatably connected to a support plate 2, a sensor probe 8 is installed on the end of the support plate 2 facing away from the rotating bolt 1, and a connecting line 7 of the sensor probe 8 extends out of the shell 5 through the through slot 6.

[0034] The outer shell 5 is made of wear-resistant material to ensure its stability and durability under complex conditions and environments.

[0035] The position of the support plate 2 in the housing 5 is adjusted by rotating the bolt 1 to accurately control the position of the sensor probe 8 so that the sensor probe 8 can be closely contacted with the component to be detected.

[0036] The present invention can effectively protect the sensor probe 8 through the shell 5, and connect the connecting parts through the connecting piece 9, so that several shells 5 can be effectively and stably installed on different components that need to be detected; the present invention does not require a bracket, is easy to operate and can be tied tightly, avoiding the disadvantages of using metal brackets, rubber band binding sleeves, etc.

[0037] In a further optimized solution, the bottom of the housing 5 is hollow, so that the sensor probe 8 can be effectively placed in the housing 5 .

[0038] According to a further optimized solution, the connection portion includes a screw rod 3 fixedly connected to the outer wall of the housing 5 , and a strap eye 4 is rotatably connected to the screw rod 3 .

[0039] Further optimizing the scheme, the two ends of the screw rod 3 extending out of the strap ring 4 are respectively threadedly connected with nuts. The nuts facilitate the installation and removal of the strap ring 4.

[0040] In a further optimized solution, the connecting member 9 is a strap or buckle. The length of the strap or buckle is adjusted according to the size, shape and other factors of the detected component to adjust the tightness, providing a flexible fixing solution, which is convenient for installation and disassembly in various complex environments and conditions.

[0041] The screw 3 is made of high-strength material, and its surface should be specially treated to increase its durability such as corrosion resistance to avoid breakage when adjusting the tightness of the strap or buckle, which may cause the housing 5 to loosen and fall off, and the sensor probe 8 to fall off and be damaged.

[0042] As a further optimization scheme, a shock absorbing material is embedded inside the support plate 2. The shock absorbing material can absorb and reduce the vibration generated when the sensor probe 8 is working, protect the internal components of the sensor probe 8, and reduce the influence of external factors on the signal received by the sensor probe 8.

[0049] S4. Place the housing 5 on the component to be detected; make the end of the housing 5 where the sensor probe 8 is installed abut against the outer wall of the component to be detected.

[0050] S5. The connecting piece 9 is installed between the strap rings 4 on opposite sides of two adjacent shells 5; the strap ring 4 rotates along the screw rod 3 so that the connecting piece 9 can effectively connect the two adjacent shells 5.

[0051] S6. Adjust the connecting member 9, that is, adjust the length of the strap or buckle to adjust the tightness, so that the housing 5 is positioned on the component to be tested; and can effectively prevent the housing 5 from falling off or loosening.

[0052] S7. Rotate the rotating bolt 1, and the support plate 2 drives the sensor probe 8 to press against the component to be detected, so that the sensor probe 8 is coupled with the component to be detected.
