Description

Technical Field

[0001] This utility model relates to the field of magnet detection, and in particular to a magnet detection device. Background Technology

[0002] A magnet testing device is used to measure and detect the properties of magnets or magnetic materials. A gaussmeter is one type of magnet testing device; it is a precision instrument specifically designed to measure magnetic field strength, also known as a teslameter. Based on the Hall effect principle, it uses a Hall sensor to detect the static or dynamic magnetic flux density of an object at a point in space. Readings are typically expressed in gauss (Gs) or tesla (T). Gaussmeters can be used to measure the surface magnetism of permanent magnets, air gap magnetic fields, residual magnetism in bearings and metal workpieces, and leakage magnetic fields. They are widely used in scientific research, industrial production, and electronic equipment testing. They offer advantages such as a wide measuring range, high accuracy, ease of operation, and portability. Traditional gaussmeter probes often have protective sleeves to protect the detection probe from external impacts, preventing damage and ensuring the accuracy and reliability of the gaussmeter during measurement. However, the protective cover and the probe are often designed separately, such as the gaussmeter probe proposed in patent application CN202121742016.1. Therefore, when the protective cover is removed from the probe, it needs to be stored separately, which makes the protective cover easy to lose. Therefore, a magnet detection device is needed to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a magnet detection device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A magnet detection device includes a gaussmeter body, a probe structure mounted on the gaussmeter body, and two protective components rotatably mounted on the probe structure. Each protective component consists of a protective shell structure, a mounting connecting arm, and an adsorption magnet. The mounting connecting arm is fixedly mounted at one end of the protective shell structure, and the adsorption magnet is fixedly mounted inside the mounting connecting arm. Four fixed magnets are symmetrically fixedly mounted on the probe structure, and the adsorption magnet is attracted to the fixed magnets.

[0006] Preferably, the probe structure consists of a grip, a connecting wire, and a detection probe. The connecting wire and the detection probe are both fixedly installed on the grip, and the connecting wire is also connected to the gaussmeter body.

[0007] Preferably, the grip handle on the probe structure has two symmetrically provided mounting and storage slots at both ends, and two symmetrically provided first magnet slots on the inner wall of the mounting and storage slots. A mounting and fixing shaft is fixedly installed in the mounting and storage slots, and the mounting and fixing shaft is located between the two first magnet slots.

[0008] Preferably, the fixing magnet is fixedly installed in the first magnet slot opened on the grip.

[0009] Preferably, the two protective shell structures on the two protective components are fitted onto the detection probe rod on the probe structure.

[0010] Preferably, the mounting connecting arm on the protective component is rotatably mounted in the mounting and storage groove. The mounting connecting arm has a mounting shaft hole, and the mounting connecting arm is rotatably mounted on the mounting fixing shaft through the mounting shaft hole. The mounting connecting arm also has a second magnet groove, and the adsorption magnet is fixedly mounted in the second magnet groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By rotating the protective component onto the probe structure, the protective component and the probe structure are designed as a single unit, thus avoiding the problem of the protective component needing to be stored separately when not in use and being easily lost. By setting a fixing magnet on the probe structure, which works in conjunction with the adsorption magnet on the protective component, the protective component can be easily fixed, thereby improving the efficiency of the magnet detection device.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a magnet detection device includes a gaussmeter body 1, a probe structure 2 mounted on the gaussmeter body 1, and two protective components 3 rotatably mounted on the probe structure 2. Each protective component 3 consists of a protective shell structure 12, a mounting connecting arm 13, and an adsorption magnet 11. The mounting connecting arm 13 is fixedly mounted at one end of the protective shell structure 12, and the adsorption magnet 11 is fixedly mounted inside the mounting connecting arm 13. Four fixed magnets 4 are symmetrically fixedly mounted on the probe structure 2, and the adsorption magnet 11 is attracted to the fixed magnets 4. In use, the protective components 3 are first opened to expose the detection probe 7. Then, the gaussmeter body 1 is turned on. After powering on, calibration is performed, including zero-point calibration and range calibration. Next, the detection probe 7 on the probe structure 2 is aligned with the point to be measured, maintaining instrument stability. Simultaneously, the detection probe 7 on the probe structure 2 can be moved appropriately to obtain more comprehensive data. Finally, the measurement results are read and recorded, including the location of the measurement point, time, and magnetic field strength value. After use, the detection probe 7 needs to be protected using the protective components 3.

[0022] Finally, by rotating the protective component 3 on the probe structure 2, the protective component 3 and the probe structure 2 are designed as a single unit, which avoids the problem that the protective component 3 needs to be stored separately when not in use and is therefore easily lost. By setting the fixing magnet 4 on the probe structure 2, which works with the adsorption magnet 11 on the protective component 3, the protective component 3 can be easily fixed, thereby improving the efficiency of the magnet detection device.

[0023] Specifically, the probe structure 2 consists of a grip handle 5, a connecting wire 6, and a detection probe 7. Both the connecting wire 6 and the detection probe 7 are fixedly mounted on the grip handle 5, and the connecting wire 6 is also connected to the gaussmeter body 1. Two symmetrical mounting and storage slots 8 are provided at both ends of the grip handle 5 on the probe structure 2. Two symmetrical first magnet slots 10 are provided on the inner wall of each mounting and storage slot 8. A mounting and fixing shaft 9 is fixedly installed within each mounting and storage slot 8, located between the two first magnet slots 10. A fixing magnet 4 is fixedly installed within the first magnet slot 10 on the grip handle 5. Two protective shell structures 12 on the two protective components 3 are fitted onto the detection probe 7 on the probe structure 2. A mounting connecting arm 13 on the protective component 3 is rotatably mounted within the mounting and storage slot 8. A mounting shaft hole 14 is provided on the mounting connecting arm 13, allowing it to be rotatably mounted on the mounting and fixing shaft 9 through the mounting shaft hole 14. A second magnet slot 15 is provided on the arm 13. The magnet 11 is fixedly installed in the second magnet slot 15. When the protective component 3 is opened or closed, the protective component 3 can be rotated around the mounting shaft 9. When the protective component 3 rotates backward on the mounting shaft 9 and the protective component 3 disengages from the front fixed magnet 4 and is attracted to the rear fixed magnet 4, and at the same time the protective shell structure 12 on the protective component 3 moves to the rear of the grip handle 5, the protective component 3 is opened. At this time, the detection probe 7 will be exposed and can then be used. When the protective component 3 rotates forward on the mounting shaft 9 and the protective component 3 disengages from the rear fixed magnet 4 and is attracted to the front fixed magnet 4, and at the same time the protective shell structure 12 on the protective component 3 moves to the front of the grip handle 5, the two protective shell structures 12 on the two protective components 3 will surround and protect the detection probe 7.
