Technical Field
[0001] This utility model belongs to the field of electromagnetic detection technology, and in particular relates to a portable electromagnetic detection device for electromechanical products. Background Technology
[0002] Portable electromagnetic testing devices are commonly used tools in the production, maintenance, and on-site testing of electromechanical products. They are used to measure key parameters such as electromagnetic field strength and radiation leakage around equipment. In practical applications, these devices usually need to be operated by hand so that the testing head can be flexibly aimed at different parts of the product to be tested.
[0003] However, the acquisition of electromagnetic signals is often very sensitive to the angle and distance between the detection head and the source under test. Any slight deviation may lead to significant deviations in the measurement results. In long-term or precise positioning detection tasks, operators need to hold the detection device with their hands and maintain a fixed posture, which can easily lead to hand fatigue and involuntary shaking, making it difficult to ensure the stability of the detection angle, resulting in distortion of the detection signal and even misjudgment of the electromagnetic performance of the product.
[0004] In addition, the on-site testing environment is usually quite complex. There may be contaminants such as liquid or metal dust on the ground or workbench, or there may be high-temperature surfaces. When operators need to pause operation to record data or perform other work, they have to place the testing device directly on these surfaces. This will not only cause the device casing to be contaminated or corroded, affecting its service life and cleanliness, but more seriously, if the temperature of the surface is too high, the heat will accelerate the aging of the precision electronic components and wire insulation layers inside the device through heat conduction, bringing safety hazards. Existing portable testing devices generally lack consideration for these actual use scenarios in their structural design.
[0005] Therefore, this utility model proposes a portable electromagnetic testing device for electromechanical products to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems existing in the portable electromagnetic detection device, such as difficulty in stabilizing the detection head at special angles, resulting in signal distortion, and susceptibility to pollution, corrosion and thermal damage when the device is placed in complex environments, this utility model aims to provide a portable electromechanical product electromagnetic detection device with an improved structure that can effectively solve the above problems.
[0007] This utility model provides a portable electromagnetic testing device for electromechanical products, including: a detector, a testing head, a self-adjusting mechanism, and a support mechanism.
[0008] The self-adjusting mechanism is used to achieve arbitrary adjustment and locking of the detection head angle, and includes a ring block, a fastening rubber block, a nut, a bolt, a washer, a motion shaft, a drive block, and a wire groove.
[0009] Furthermore, the support mechanism is used to provide stable support for the detector, and it includes a housing, a pressing head, a guide bar, a pushing column, a fixing block, a rotating shaft, support legs, and springs.
[0010] The self-adjusting mechanism is rotatably connected to the detector and the detection head, and the support mechanism is disposed on the detector. Together with the detector, they form a fully functional whole.
[0011] Preferably, the ring block is fixed to the detector, and the fastening rubber block is threadedly engaged with the nut and the bolt. When the nut rotates, it can drive the fastening rubber blocks to move closer to each other and squeeze the gasket, so that the gasket is fixed on both sides of the motion shaft.
[0012] Preferably, the ring block has a structure with a small opening at the end near the fastening rubber block and a large opening at the end away from the fastening rubber block, which is used to limit the maximum distance between the fastening rubber blocks.
[0013] Preferably, the drive block is fixedly connected to the outer wall of the motion shaft, and the wire groove is fixedly connected to the bottom of the drive block, so that the rotation of the drive block can drive the motion shaft and the wire groove to rotate synchronously.
[0014] Preferably, in the support mechanism, the pressing head is slidably disposed inside the housing, the guide strip is fixed to the pressing head, and the guide strip is hinged to the jacking column.
[0015] Preferably, the actuating column is used to movably limit the support leg within the fixed block, and the support leg is hinged to the rotating shaft. The spring is fixed to the lower pressure head, and the spring is fixed to the actuating column.
[0016] Preferably, when the pressing head slides, the guide bar can pull the jacking column to move, thereby releasing the restriction on the support leg and allowing the support leg to rotate along the rotation axis for retraction and extension.
[0017] Preferably, after the support leg is in place, the spring is used to push up the lower pressure head to reset it, and the spring is also used to push up the jacking column, so that the jacking column slides back into the rotating shaft to lock the support leg.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model, by setting a self-adjusting mechanism, uses the rotation of the nut to drive the tightening rubber block to squeeze the gasket, thereby generating friction to fix the motion axis of the connected detection head at any angle. This solves the problem in the prior art that electromagnetic signal acquisition is sensitive to angle, and it is difficult to maintain the correct angle when the detection head is held for a long time, which easily leads to angle deviation, resulting in signal distortion and equipment misjudgment. It achieves the technical effect that the detection head can be suspended and fixed at any angle, making operation flexible and convenient, and improving the accuracy and reliability of the detection signal.
[0020] 2. This utility model, by setting up a support mechanism, allows the guide strip to pull the push column away from the limit of the support leg by pressing down the pressure head, thus realizing the unfolding and retraction of the support leg. This solves the problem in the prior art where the detector is in direct contact with the placement surface, making it susceptible to contamination and corrosion from accumulated liquid and dust, or accelerated aging of the insulation layer of the wires inside the cavity due to heat conduction at high temperatures. It achieves the technical effect of isolating the detector body from the placement surface, effectively preventing equipment contamination, corrosion and heat damage, and extending the service life of the equipment.
[0021] 3. This utility model solves the problem in the prior art where the internal connecting wires are easily damaged by repeated bending and stretching when the detection head rotates at multiple angles by setting a wire groove at the bottom of the driving block that rotates synchronously with it. This achieves the technical effect of effectively protecting the internal wires, avoiding circuit failures, and improving the overall reliability and durability of the device.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Example:
[0030] Please refer to Figures 1 to 4 This utility model provides a portable electromagnetic testing device for electromechanical products, which aims to solve the structural defects in the prior art, such as the difficulty in accurately fixing the detection head at special angles, which leads to signal distortion, and the device being susceptible to contamination and corrosion and accelerated aging of the internal wire insulation layer when placed.
[0031] like Figure 1 and Figure 2 As shown, the portable electromechanical product electromagnetic detection device includes a detector 1 and a self-adjusting mechanism 2 that is rotatably connected to the front end of the detector 1 and forms an organic whole with it. The detector 1 serves as the main body and core processing platform of the entire device, carrying out information processing and display functions, and is also equipped with a support mechanism 3. The self-adjusting mechanism 2 is used to achieve precise adjustment and stable fixation of the angle between the detection head 4 and the detector 1, thereby ensuring the accuracy of electromagnetic signal acquisition.
[0032] To solve the above-mentioned technical problems, the portable electromechanical product electromagnetic detection device also includes a self-adjusting mechanism 2, and the self-adjusting mechanism 2 forms a specific structural cooperation and connection relationship with the detector 1 and the detection head 4.
[0033] Please refer to the following carefully. Figure 3 and Figure 4 The core structure will be described in detail below:
[0034] The self-adjusting mechanism 2 includes a ring block 201, a fastening rubber block 202, a nut 203, a bolt 204, a washer 205, a moving shaft 206, a driving block 207, and a wire groove 208. The ring block 201 is fixedly connected to the side of the detector 1. The ring block 201 has a structure with a small opening at the end near the fastening rubber block 202 and a large opening at the end away from the fastening rubber block 202. This structure is used to limit the maximum distance between the fastening rubber blocks 202 to prevent excessive compression. The fastening rubber block 202 is columnar or block-shaped, with a threaded hole inside, and is screwed into the bolt 204 through threaded engagement. The nut 203 is sleeved on the outer wall of the bolt 204 and engages with the thread of the bolt 204, allowing it to rotate along the axial direction of the bolt 204. The washer 205 is circular or annular, and multiple washers 205 are stacked and arranged between the fastening rubber blocks 202. The motion shaft 206 is cylindrical, passes through the center of the gasket 205, and extends through the ring block 201. The drive block 207 is fixedly connected to the outer wall of the motion shaft 206, with one end mechanically connected to the detection head 4 and the other end fixedly connected to the bottom of the wire groove 208. The wire groove 208 is a U-shaped groove that extends along its length and is used to store and protect the internal wires.
[0035] In the assembled state, the fastening rubber block 202 is installed in the hole of the ring block 201 by bolts 204. The bolts 204 pass through the center hole of the motion shaft 206, and the washers 205 surround the outer periphery of the motion shaft 206 and are located on both sides of the fastening rubber block 202. When the user moves the drive block 207 to adjust the angle of the detection head 4, the nut 203 rotates on the outer wall of the bolt 204, causing the fastening rubber blocks 202 to move closer together, squeezing the washers 205, and generating friction between the washers 205 and the motion shaft 206. This friction allows the drive block 207 to remain stably at any angle it is moved to, thereby achieving the suspension and fixation of the detection head 4 at any angle position, effectively avoiding the problem of electromagnetic signal acquisition being sensitive to angle. At the same time, the rotation of the drive block 207 drives the motion shaft 206 and the wire groove 208 to rotate synchronously, ensuring that the internal wires move smoothly with the angle adjustment and preventing the wires from being damaged by repeated bending or pulling.
[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:
[0037] As a preferred embodiment, in order to limit the range of movement of the fastening rubber block 202 and prevent excessive compression or loosening, please refer to... Figure 3 and Figure 4 The ring block 201 has a structure with a small opening at the end near the fastening rubber block 202 and a large opening at the end away from the fastening rubber block 202. This structure can precisely control the maximum distance between the fastening rubber blocks 202, ensuring the stability and service life of the self-adjusting mechanism 2.
[0038] As another preferred embodiment, to ensure smooth movement of the conductor with angle adjustment and to avoid damage, please refer to... Figure 3 and Figure 4 The drive block 207 is fixedly connected to the outer wall of the motion shaft 206, and the wire groove 208 is fixedly connected to the bottom of the drive block 207. This fixed connection relationship allows the motion shaft 206 and the wire groove 208 to rotate synchronously when the drive block 207 rotates, thereby effectively protecting the internal wires and preventing damage to the circuit caused by repeated bending or pulling.
[0039] As another preferred embodiment, in order to achieve smooth operation and accurate positioning of the support mechanism 3, please refer to... Figure 3 and Figure 4 The pressing head 302 is slidably disposed inside the housing 301, and the guide strip 303 is fixed on the pressing head 302 and hinged to the actuating column 304. In addition, the actuating column 304 is used to movably limit the support leg 307 inside the fixing block 305, and the support leg 307 is hinged to the rotating shaft 306 to realize the retraction and extension around the rotating shaft 306.
[0040] Furthermore, to achieve the automatic locking and reset function of support mechanism 3, please refer to... Figure 3 The device includes two independent springs 308: spring 308 is fixed to the lower pressure head 302 and is used to lift the lower pressure head 302; spring 308 is fixed to the lifting column 304 and is used to lift the lifting column 304.
[0041] In operation, when the pressing head 302 is pressed and slid, the guide bar 303 pulls the actuating column 304 to move, releasing the restriction on the support leg 307, allowing the support leg 307 to rotate along the rotating shaft 306 for retraction and extension. Once the support leg 307 is fully extended and in its supporting position, the spring 308 lifts the pressing head 302, and the guide bar 303 immediately disengages from the actuating column 304. Subsequently, the spring 308 lifts the actuating column 304, causing it to slide back into the rotating shaft 306, locking the support leg 307 and preventing accidental retraction.
[0042] Working principle: When encountering a special angle, the self-adjusting mechanism 2 can be suspended at any angle position, both vertically and horizontally. When the driving block 207 is moved, as the nut 203 rotates on the outer wall of the bolt 204, it causes the fastening rubber blocks 202 to move closer together. During the process of the fastening rubber blocks 202 moving closer together, because the ring block 201 fixed on the detector 1 has a smaller opening at one end and a larger opening at the other end, the maximum distance between the fastening rubber blocks 202 can be limited. Subsequently, during the process of the fastening rubber blocks 202 moving closer together, multiple pads 205 will be squeezed and brought closer to the motion shaft 206. Multiple gaskets 205 are fixed to both sides of the motion shaft 206 by the compression of the fastening rubber block 202, thereby realizing that the drive block 207, which is fixed to the outer wall of the motion shaft 206, will stay at the angle it is turned to. As the drive block 207 moves, the wire groove 208 connected to the bottom of the drive block 207 will also move, thereby preventing damage to the circuit. In addition, it also prevents the problem of signal distortion and equipment misjudgment caused by the angle deviation due to the sensitivity of electromagnetic signal acquisition to angle, the inconvenience of holding the detection head 4 downward for a long time, the difficulty in recording and maintaining the correct angle.
[0043] When the support mechanism 3 is needed to support the entire detector 1, the pressing head 302 sliding inside the housing 301 is pressed. As the pressing head 302 slides inside the housing 301, multiple guide bars 303 fixed on the pressing head 302 pull the actuating column 304. As the actuating column 304 is pulled away from the limit of the support leg 307 inside the fixed block 305 by the guide bars 303, the support leg 307 can rotate along the rotation axis 306 from being close to the detector 1 to vertically supporting the detector 1. After the support leg 307 is supported, the spring 308 fixed to the pressing head 302 pushes up the pressing head 302. Subsequently, the guide bar 303 disengages from the top post, and the spring 308 fixed to the actuating post 304 lifts the actuating post 304, causing the actuating post 304 to slide back into the rotating shaft 306 to fix the support leg 307 and prevent the support leg 307 from retracting. When it is necessary to retract the support leg 307, the pressure head 302 is pressed down again, causing the actuating post 304 to disengage from the limit on the support leg 307. As the actuating post 304 extends and retracts, it achieves the support and release of the detector 1, thereby preventing the detector 1 from being contaminated and corroded by the liquid and dust on the placement surface, and preventing the heat conduction at high temperature from accelerating the aging of the insulation layer of the wires inside the cavity.
