Description

Technical Field

[0001] The utility model relates to the technical field of magnetometers, in particular to a position adjusting device for a magnetometer probe. Background Art

[0002] A magnetometer is an instrument for measuring magnetic induction intensity. Commonly used portable magnetometers usually have a probe. When detecting magnetic intensity, the position of the probe needs to be adjusted. When detecting the magnetic intensity inside a hole, a position adjusting device is required to insert the probe into the hole. During the insertion process, since the probe has no protection and directly rubs against the hole wall, it is easy to cause damage to the probe. Moreover, there is less research on the position adjusting device for magnetometer probes in the prior art. Therefore, in actual work, a position adjusting device with a function of protecting the probe is needed, and the probe should be fully extended after reaching the position to complete the magnetic intensity detection, which will be practical. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a position adjusting device for a magnetometer probe, which can insert the probe into a specified position and avoid the probe from being scratched and damaged, and has good practicability.

[0004] A position adjusting device for a magnetometer probe of the utility model includes a probe; it also includes a support tube, a protective sleeve, a baffle, a spring plate, a slider and a push cylinder. The probe is installed at the lower end of the support tube. The protective sleeve is sleeved outside the probe, and the protective sleeve is through up and down. A plurality of baffles are hinged at the lower end of the protective sleeve. One end of a plurality of spring plates is connected with the protective sleeve, and the other ends of the plurality of spring plates are respectively connected with the plurality of baffles. The elastic forces of the plurality of spring plates close the plurality of baffles towards the middle of the protective sleeve, and the closed plurality of baffles close the lower port of the protective sleeve. A long chute is arranged on the outer wall of the support tube. The slider is installed at the upper end of the protective sleeve, and the slider extends into the interior of the support tube through the long chute. The fixed end of the push cylinder is installed on the slider, and the piston rod of the push cylinder is connected with the support tube; during work, the piston rod of the push cylinder contracts, so that the fixed end of the push cylinder pushes the slider to move along the long chute towards the lower end of the support tube, so that the slider drives the protective sleeve to move towards the lower end of the probe, so that the protective sleeve covers the probe. The lower end of the protective sleeve extends out of the lower end of the probe. The elastic forces of the plurality of spring plates close the plurality of baffles to close the lower port of the protective sleeve. The probe and the protective sleeve are inserted into the hole to be detected through the support tube. During the insertion process, the protective sleeve and the plurality of baffles cover and protect the probe. When the probe reaches the specified position, the piston rod of the push cylinder extends, so that the fixed end of the push cylinder drives the slider to move along the long chute towards the upper end of the support tube, so that the protective sleeve rises relative to the probe, and the probe pushes open the plurality of baffles and extends out from the lower end of the protective sleeve. At this time, the probe detects the magnetic intensity in the hole, which can insert the probe into the specified position and avoid the probe from being scratched and damaged, and has good practicability.

[0005] Preferably, it further includes a connecting ring and a flexible shaft. The lower end of the connecting ring is connected to the upper end of the support pipe, and the lower end of the flexible shaft is connected to the upper end of the connecting ring.

The flexible shaft can be received inside the shaft tube, and the lower end of the flexible shaft is inserted and matched with the shaft tube. During non-working hours or when the degree of hole bending is low, the flexible shaft is received into the shaft tube, and the lower end of the flexible shaft is inserted and matched with the lower end of the shaft tube to achieve stable storage of the flexible shaft, shorten the structural length, and facilitate carrying, thereby realizing the soft-hard conversion of the connection between the support pipe and the shaft tube, with good practicability.

[0007] Preferably, it further includes two first ear plates, an upper tube, two second ear plates, a plurality of connection holes, and a cross shaft. Two first ear plates are oppositely arranged at the upper end of the shaft tube, and two second ear plates are oppositely arranged at the lower end of the upper tube. The two first ear plates and the two second ear plates are arranged in an alternating manner. Connection holes are provided on both the two first ear plates and the two second ear plates.

The two first ear plates at the upper end of the shaft tube and the two second ear plates at the lower end of the upper tube are rotatably connected through the cross shaft to achieve universal adjustment of the direction and orientation of the shaft tube and the upper tube, improving flexibility.

[0008] Preferably, the plurality of connection holes are all oblong holes; the four short shafts of the cross shaft respectively move in the plurality of connection holes to improve the flexibility of the shaft tube and the upper tube.

At this time, the angle between the shaft tube and the upper tube can be flexibly adjusted. Move the upper tube closer to the shaft tube so that the first ear plate and the second ear plate are inserted into each other. Rotate the threaded sleeve in the reverse direction so that the internal thread of the threaded sleeve is rotatably screwed with the first external thread and the second external thread, and the threaded sleeve clamps the first ear plate and the second ear plate tightly, thereby rigidly connecting the shaft tube and the upper tube. At this time, the angle between the shaft tube and the upper tube cannot be flexibly adjusted, which is convenient for laterally supporting the probe and extending it, with good practicability.

[0010] Preferably, it further includes a tool chamber, and the tool chamber is arranged inside the upper tube; the tool chamber can hold common tools for disassembling and repairing the probe and other common accessories, facilitating the detection work.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: During operation, the piston rod of the pushing cylinder contracts, causing the fixed end of the pushing cylinder to push the slider along the long chute towards the lower end of the support tube, so that the slider drives the protective sleeve tube towards the lower end of the probe, enabling the protective sleeve tube to cover the probe completely. The lower end of the protective sleeve tube extends beyond the lower end of the probe.

During the insertion process, the protective sleeve tube and multiple baffles cover and protect the probe. When the probe reaches the designated position, the piston rod of the pushing cylinder extends, causing the fixed end of the pushing cylinder to drive the slider along the long chute towards the upper end of the support tube, so that the protective sleeve tube rises relative to the probe, and the probe pushes open multiple baffles and extends out from the lower end of the protective sleeve tube. At this time, the probe detects the magnetic intensity in the hole, can insert the probe into the designated position and prevent the probe from being scratched or damaged, and has good practicability.
