Low-frequency magnetic field receivers, devices used to receive, process, and analyze low-frequency magnetic field signals, play a vital role in today's scientific and technological landscape. In practical applications, whether in field exploration, industrial production, or transportation, these devices are inevitably affected by mechanical vibration.

[0003] Currently, in the protection design of some low-frequency magnetic field receiving devices, some devices rely solely on simple shell packaging as the main means of protection. The structure of this shell is relatively simple, and its main design goal is to achieve basic physical isolation. Since vibration problems may occur due to the operation of the machine during actual use, the continuous vibration transmitted to the low-frequency magnetic field receiving device can easily cause the solder joints of the internal electronic components and circuit boards to loosen, the circuit boards to break, or the internal connection lines to be disconnected. The few existing receiving devices that can clamp the body of the low-frequency magnetic field receiving device can alleviate the pulling of the vibration force on the solder joints of the parts on the receiving device, but it is not easy to control the clamping force, which can easily lead to the problem of excessive clamping force damaging the body or insufficient clamping force preventing stable positioning.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a low-frequency magnetic field receiving device protection mechanism, comprising a low-frequency magnetic field receiver 1 and a shell 2 arranged on the outside of the low-frequency magnetic field receiver 1, a clamping assembly fixedly connected inside the shell 2, the clamping assembly comprising two electric push rods 5 slidably connected to the inner wall of the shell 2, one end of the electric push rod 5 is fixedly connected to a connecting plate 7, one side of the connecting plate 7 is fixedly connected to a telescopic rod 8, a spring 9 is fixedly sleeved on the outside of the telescopic rod 8, one end of the spring 9 is fixedly connected to a protective plate 11, the protective plate 11 is abutted against the low-frequency magnetic field receiver 1, a trigger button 10 is fixedly connected to the protective plate 11, the connecting plate 7 cooperates with the trigger button 10 to abut, the trigger button 10 is electrically connected to the electric push rod 5, a control button 6 is fixedly connected to the outer wall of the shell 2, and the control button 6 is electrically connected to the electric push rod 5.

[0025] During specific implementation: the low-frequency magnetic field receiver 1 is placed inside the housing 2, and the front end is adapted to abut against the abutment block 3 on one side of the abutment block 3, and then the two control buttons 6 are pressed to start the two electric push rods 5 to perform relative horizontal clamping movement, and then the two protective plates 11 will respectively abut against the two sides of the lower end of the low-frequency magnetic field receiver 1 to firmly clamp the low-frequency magnetic field receiver 1. When the clamping is stable, since the electric push rod 5 has not stopped running, it will push the connecting plate 7 to compress the telescopic rod 8 and the spring 9, and then touch the trigger button 10. Since the trigger button 10 is electrically connected to the electric push rod 5, the electric push rod 5 can be stopped.

[0026] It should be noted that the low-frequency magnetic field receiver 1 includes a circular metal ring and a modified cylindrical shape. The metal ring is located at the top and is used to support and fix other components; the plastic block is located at the bottom and serves as the main part of the entire assembly. On one side of the plastic block, a small N-shaped fixing piece is provided for installing or fixing other components to achieve multiple connection and fixing functions.

[0027] The trigger button 10 and the connecting plate 7 are matched and offset by the thrust of the electric push rod 5, which can not only achieve a stable clamping of the low-frequency magnetic field receiver 1, but also prevent the risk of excessive clamping force on the low-frequency magnetic field receiver 1. At the same time, it can also ensure the accuracy of the clamping position, reduce the steps of manual observation operation, and realize automation.

[0028] See Figure 3 A fixed block 13 is fixedly connected to the bottom wall of the shell 2, and a lifting assembly is provided on the fixed block 13. The lifting assembly includes a first connecting rod 14 rotatably connected to one side of the fixed block 13, one end of the first connecting rod 14 is rotatably connected to the second connecting rod 15, and one end of the second connecting rod 15 is rotatably connected to the mounting block 17. The upper surface of the mounting block 17 is fixedly connected to the base plate 12, and the base plate 12 is movably connected in the shell 2. One side of the second connecting rod 15 is rotatably connected to a nut 18, and a bidirectional screw rod 19 is inserted into the inner thread of the nut 18. One end of the bidirectional screw rod 19 is transmission-connected to a forward and reverse motor 20, which is fixedly connected in the shell 2, and the other end of the bidirectional screw rod 19 is rotatably mounted on the side wall of the shell 2.

[0029] The provided lifting assembly can smoothly push the low-frequency magnetic field receiver 1 upward, making it more convenient for the staff to put it in or take it out. Since the low-frequency magnetic field receiver 1 is moved upward as a whole, it can also be convenient for observation and maintenance; the provided nut 18 cooperates with the bidirectional screw rod 19, so that the nut 18 can slide on the bidirectional screw rod 19, thereby realizing the lifting of the base plate 12, ensuring the overall stability.

[0030] See Figure 3A first pin 16 is provided at one end of the first connecting rod 14 , and the first pin 16 is rotatably inserted into the first connecting rod 14 , the second connecting rod 15 and the nut 18 .

[0031] By setting a first pin shaft 16 connected to the first connecting rod 14, the second connecting rod 15, and the nut 18, it can be ensured that the first connecting rod 14 and the second connecting rod 15 can rotate smoothly without restriction, and at the same time can be connected to the nut 18, making the transmission more coherent, making the overall device more transmission-oriented, and ensuring the stability of the device body.

[0032] See Figure 3 A second pin is also provided between the fixed block 13 and the first connecting rod 14 , and the second pin is rotatably inserted between the fixed block 13 and the first connecting rod 14 .

[0033] By rotatably inserting a second pin between the fixed block 13 and the first connecting rod 14 , the fixed block 13 and the first connecting rod 14 can be kept rotating while also being kept stable, thereby ensuring the overall stability and continuity of the device.

[0034] See Figure 3 There are two groups of lifting components, and the two groups of lifting components are symmetrically distributed.

[0035] By setting the two sets of lifting components symmetrically, it can be ensured that the lifting components are more stable during operation and have a stronger bearing capacity.

[0036] See Figure 5 The top of the housing 2 is fixedly hinged with a top cover 23, and one side of the top cover 23 is fixedly connected with a handle 4, which is provided with an integrally formed anti-slip pattern.

[0037] The top cover 23 is provided so that the housing 2 can be set to a closed state when not in use, preventing external impurities from affecting the operation of the low-frequency magnetic field receiver 1. At the same time, when the low-frequency magnetic field receiver 1 is placed, taken, adjusted, or repaired, the top cover 23 can be opened more conveniently, making operation more convenient; the top cover 23 is hinged to the top of the housing 2, so that the top cover 23 can be opened or closed freely, reducing the difficulty of operation; the handle 4 is provided to facilitate the operator to apply force, and the handle 4 is provided with an integrally formed anti-slip pattern to increase friction with the operator's hand, thereby reducing the risk of improper operation.

[0038] See Figure 3 An L-shaped plate 21 is provided on the outside of the forward and reverse motor 20 , and the L-shaped plate 21 is fixedly connected to the inner wall of the shell 2 . A switch 22 is fixedly connected to the outer wall of the shell 2 , and the switch 22 is electrically connected to the forward and reverse motor 20 .

[0039] The L-shaped plate 21 can provide a stable supporting platform for the forward and reverse motor 20 , while maintaining good heat dissipation, thereby ensuring stable operation of the forward and reverse motor 20 .

[0040] See Figure 2 The top of the low-frequency magnetic field receiver 1 is matched with an abutment block 3 , and the abutment block 3 is fixedly connected to the top of the bottom plate 12 .

[0041] By cooperating with the low-frequency magnetic field receiver 1 and abutting against each other, the position of the low-frequency magnetic field receiver 1 can be effectively fixed and its deviation can be reduced. At the same time, the low-frequency magnetic field receiver 1 can be simply limited so that the lower end of the low-frequency magnetic field receiver 1 can be just in the middle of the two groups of clamping components, ensuring the stability of the clamping.

[0042] It should be noted that in order to ensure the stable sliding of the electric push rod 5, we can open T-slots on both sides of the inner wall of the shell 2 (not shown in the figure), and then set a T-block on one side of the electric push rod 5 (not shown in the figure). The T-block can be slidably buckled in the T-slot, so that the electric push rod 5 can only slide vertically up and down, thereby improving the stability during sliding. Since the T-slot and T-block are both existing technologies, they will not be explained in detail in this description.

[0043] Working principle: When using this device, first place the low-frequency magnetic field receiver 1 inside the shell 2, and the front end is adapted to abut against one side of the abutment block 3, then press the two control buttons 6 to start the two electric push rods 5 to perform relative horizontal clamping movement, and then the two protective plates 11 will respectively abut against the two sides of the lower end of the low-frequency magnetic field receiver 1 to firmly clamp the low-frequency magnetic field receiver 1. When the clamping is stable, since the electric push rod 5 has not stopped running, it will push the connecting plate 7 to compress the telescopic rod 8 and the spring 9, and then touch the trigger button 10. Since the trigger button 10 is electrically connected to the electric push rod 5, the electric push rod 5 can be stopped. The trigger button 10 and the connecting plate 7 are matched and offset by the thrust of the electric push rod 5, which can achieve firm clamping of the low-frequency magnetic field receiver 1. It can also prevent the risk of excessive clamping force on the low-frequency magnetic field receiver 1, while ensuring the accuracy of the clamping position, reducing the steps of manual observation and operation, and realizing automation; when the low-frequency magnetic field receiver 1 needs to be taken out or put in, first press the switch 22, then drive the forward and reverse motor 20 to operate, and then the forward and reverse motor 20 will drive the bidirectional screw rod 19 to rotate, thereby driving the two nuts 18 threadedly connected to the bidirectional screw rod 19 to move relative to each other and move inward at the same time, thereby driving the second connecting rod 15 and the first connecting rod 14 to move inward, and then pushing the mounting block 17 to drive the bottom plate 12 to move upward, and the low-frequency magnetic field receiver 1 can be smoothly pushed upward, making it more convenient for the staff to put in or take out. Since the overall upward movement of the low-frequency magnetic field receiver 1 is also convenient for observation and maintenance.
