Description

Technical Field

[0001] The utility model relates to a fast-assembly and disassembly type hard non-metallic field magnetic probe rod, belonging to the field of mineral survey equipment. Background Art

[0002] The proton precession magnetometer is an instrument used in mineral surveys and requires a matching probe when in use.

[0003] At present, the probe rod is generally made of metal material, and each short rod section is connected by a thread, and multiple short rod sections can be assembled into a probe rod of appropriate length.

[0004] First, the threaded connection requires multiple turns of rotation, which makes the disassembly and assembly of the probe rod time-consuming and labor-intensive. Moreover, since it is a field exploration activity, improper operation and use of the probe rod, such as randomly throwing it on the ground, will cause the probe rod to come into contact with the soil and cause the threads of the threaded connection to become stuck, resulting in the probe rod being inconvenient, time-consuming and labor-intensive to disassemble and assemble when it needs to be inserted. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a quick-assembly and detachable hard non-metallic field magnetic probe rod, which is easy, convenient and fast to disassemble and assemble.

It is characterized in that the connecting structure includes a connecting part 1 with an axial limit slot on the end face and a connecting part 2 with a connecting plug on the end face. When the connecting plug is inserted into the axial limit slot, it can rotate around the central axis of the axial limit slot. The connecting plug is fixedly connected with a connecting pin shaft. The end face of the connecting part 1 is also provided with an axial give-way slot for giving way to the connecting pin shaft and a circumferential lock groove connected to the axial give-way slot; it also includes a limiting structure for limiting the connecting pin shaft in the circumferential lock groove.

[0007] Preferably, the limiting structure limits the connecting pin by axially pressing the connecting plug, and comprises a top block, a compression spring, and a spring seat, wherein one end of the compression spring presses against the spring seat, and the other end presses against the top block.

[0008] Preferably, a sliding rod connected to the top block is passed through the spring seat, and the compression spring is sleeved on the sliding rod.

[0009] Preferably, the top block has a threaded connection hole connected to the sliding rod.

[0010] Preferably, the top block and the spring seat are made of demagnetized stainless steel.

[0011] Preferably, the limiting structure includes a friction limiting surface provided in the circumferential locking groove and in frictional contact with the connecting pin shaft.

[0012] Preferably, the connecting pin is made of demagnetized stainless steel.

[0013] Preferably, the probe section is made of nylon.

[0014] Preferably, the number of the probe rod segments is 4, and one of the probe rod segments has a detection tip.

[0015] The second object of the present invention is to provide a proton precession magnetometer, comprising a magnetic probe rod as described in any of the above technical solutions. The device is easy to use because the probe rod can be disassembled and assembled easily, conveniently and quickly.

[0022] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. Example

[0023] A quick-install and disassemble hard non-metallic field magnetic probe rod, such as Figure 1-3 As shown, it is formed by connecting multiple probe rod segments 1. In the embodiment, the number of the probe rod segments 1 is 4, one of the probe rod segments 1 has a detection tip, and adjacent probe rod segments 1 are connected by a connecting structure 2.

[0024] The connecting structure 2 includes a connecting part 21 with an axial limit slot 22 on the end face and a connecting part 23 with a connecting plug 24 on the end face. The connecting part 21 and the connecting part 2 23 are respectively arranged on the two connected probe rod sections 1. The connecting part 21 and the connecting part 2 23 can be separate component structures. In this case, the connecting part 1 21 and the connecting part 2 23 are both part of the corresponding probe rod section 1. The cross-sections of the axial limit slot 22 and the connecting part 1 21 are both circular, so that when the connecting plug 24 is inserted into the axial limit slot 22, if a certain rotational force is applied, the connecting plug 24 can rotate around the center axis of the axial limit slot 22.

[0025] The connecting plug 24 is fixedly connected to a connecting pin 25, which is made of demagnetized stainless steel and arranged in the radial direction of the connecting plug 24. The end surface of the connecting portion 1 21 is also provided with an axial clearance notch 26 for the connecting pin 25 and a circumferential locking groove 27 connected to the axial clearance notch 26.

[0026] When adjacent probe rod sections 1 are connected, the connecting plug 24 on one of the probe rod sections 1 is inserted into the axial limit slot 22 of the other probe rod section 1. During the insertion process, the connecting pin 25 is also inserted into the axial yielding slot 26. Then, a certain rotational force is applied to make the connecting pin 25 enter the circumferential locking groove 27.

[0027] The magnetic probe rod further includes a limiting structure 28 for limiting the connecting pin 25 in the circumferential locking groove 27 .

[0028] One of the limiting structures 28 limits the connecting pin 25 by axially pressing the connecting plug 24. Figure 3 As shown, it comprises a top block 281, a compression spring 282, and a spring seat 283. One end of the compression spring 282 rests on the spring seat 283, while the other end rests on the top block 281. A sliding rod 284, which is connected to the top block 281, is inserted through the spring seat 283. The compression spring 282 is sleeved onto the sliding rod 284. The top block 281 has a threaded hole for connecting to the sliding rod 284, into which one end of the sliding rod 284 is screwed. The top block 281 and spring seat 283 are made of demagnetized stainless steel.

[0029] The second limiting structure 28, such as Figure 4 As shown, it includes a friction limiting surface arranged on the groove wall of the circumferential locking groove 27 and in frictional contact with the connecting pin 25. At this time, for the circumferential locking groove 27, the thickness of the circumferential locking groove 27 is slightly smaller than the diameter of the connecting pin 25. In this way, when the connecting pin 25 enters the circumferential locking groove 27, it can be automatically clamped by the circumferential locking groove 27.

[0030] After the connecting pin 25 enters the circumferential locking groove 27 , the two limiting structures 28 are finally automatically restricted in the circumferential locking groove 27 without the need for a special locking operation.

[0031] The magnetic probe rod in this case is essentially connected by a "plug-and-turn" method. Compared with the threaded connection method in the prior art, disassembly and assembly are relatively easy, convenient and quick.

[0032] Generally speaking, the probe rod is often more than 1 meter long and heavy. Therefore, in this case, the probe rod section 1 is made of nylon, which makes the entire probe rod relatively light and easy to disassemble and assemble.

[0033] The embodiment also relates to a proton precession magnetometer, comprising the magnetic probe rod described in the above solution.

[0034] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
