Technical Field

[0001] This utility model relates to the field of magnetic particle flaw detectors, specifically a portable magnetic particle flaw detector. Background Technology

[0002] Magnetic particle flaw detectors are widely used in machinery manufacturing, aerospace, railway transportation, petrochemical and other fields, mainly for inspecting ferromagnetic metal components such as steel and cast iron. In the component production process, they can detect potential defects such as cracks, inclusions, and porosity on and near the surface of components such as shafts, gears, and flanges, screening out unqualified products and ensuring that components leaving the factory meet quality standards.

[0003] Utility model patent CN219314280U discloses a portable magnetic particle flaw detector, including a flaw detector body. The top wall of the flaw detector body has a placement groove, and the bottom wall of the placement groove has a connecting hole. A winding reel is installed inside the flaw detector body. A fixing box is fixedly installed on the right side wall of the flaw detector body. A forward and reverse motor is installed inside the fixing box. A cover plate is installed at the upper end of the placement groove, and a handle is fixedly installed on the top wall of the cover plate. A pulley is fixedly installed at the lower end of the flaw detector body. This portable magnetic particle flaw detector, through the inclusion of a winding reel, a forward and reverse motor, a cover plate, and a placement groove, enhances the safety performance of the device. The winding reel, combined with the forward and reverse motor, facilitates the winding of wires into bundles for easy storage, while also increasing the automation level of the device. The cover plate and placement groove allow for the storage of unused detection devices.

[0004] In the aforementioned prior art, the flaw detector is not portable enough during use, making it inconvenient to move and use the flaw detector. Furthermore, while the motor-driven winding reel can be used to wind up and unwind the wire, it is inconvenient to limit the winding reel when the motor stops, which will affect the use of the wire. Utility Model Content

A mounting base 6 is fixedly connected to the right end of the flaw detector body 1. A motor 7 is fixedly installed inside the mounting base 6. The output end of the motor 7 is rotatably connected to the mounting base 6 and the flaw detector body 1.

An adjustment mechanism 8 is provided on the pull handle 5, and a limit mechanism 9 is provided on the winding reel 10.

[0019] Please see Figure 1 , Figure 2 , Figure 3 The adjusting mechanism 8 includes a slot 81. A slot 81 is provided inside the handle 5. A rod 82 is slidably fitted inside the slot 81. There are multiple slots 81, evenly distributed inside the handle 5. By designing multiple slots 81, the rod 82 can be inserted into slots 81 at different positions. The rod 82 is slidably connected to the connecting sleeve 4. A fixing seat 83 is slidably fitted to the outside of the rod 82. The fixing seat 83 is fixedly connected to the connecting sleeve 4. A magnetic block 84 is fixedly connected to one end of the rod 82. The magnetic block 84 is slidably connected to the fixing seat 83. A magnet 85 is fixedly connected inside the 83. A slider 86 is fixedly connected to the other end of the insertion rod 82. The slider 86 is slidably connected to the fixed seat 83. A fixed rod 87 is slidably sleeved inside the slider 86. The fixed rod 87 is fixedly connected to the fixed seat 83. A first spring 88 is provided on the outside of the fixed rod 87. One end of the first spring 88 is fixedly connected to the slider 86, and the other end of the first spring 88 is fixedly connected to the fixed seat 83. By designing the first spring 88, the force of the first spring 88 can be applied to the slider 86. By designing the adjustment mechanism 8, the relative position of the handle 5 and the connecting sleeve 4 can be easily adjusted.

[0020] Please see Figure 1 , Figure 4 The limiting mechanism 9 includes a slot 91. The take-up reel 10 has a slot 91 inside, and a ball 92 is movably fitted inside the slot 91. There are multiple slots 91, evenly distributed inside the limiting seat 93. By designing multiple slots 91, the ball 92 can roll into different positions within the slots 91. The outer side of the ball 92 is movably fitted with the limiting seat 93. The limiting seat 93 is fixedly connected to the flaw detector body 1 and rotatably connected to the take-up reel 10. The bottom of the ball 92 is movable. A support block 94 is movably connected to the support block 94, which is slidably connected to the limiting seat 93. A guide rod 95 is fixedly connected to the bottom of the support block 94, which is slidably connected to the limiting seat 93. A second spring 96 is provided on the outside of the guide rod 95. One end of the second spring 96 is fixedly connected to the support block 94, and the other end of the second spring 96 is fixedly connected to the limiting seat 93. By designing the second spring 96, the force of the second spring 96 can be applied to the support block 94. By designing the limiting mechanism 9, the stationary winding reel 10 can be limited.

[0021] The specific implementation process of this utility model is as follows: In use, the flaw detector can be lifted and carried by the handle 3. Through the hinge between the connecting sleeve 4 and the flaw detector body 1, the handle 5 can be rotated and taken out. The entire structure can be moved by pushing the handle 5, which can further improve the portability of the flaw detector. When it is necessary to adjust the length of the handle 5, simply pull the plug rod 82 upward. The plug rod 82 drives the slider 86 to slide along the fixed rod 87. The slider 86 squeezes the first spring 88. At the same time, the plug rod 82 will drive the magnetic block 84 to move. When the magnetic block 84 is attracted to the magnet 85, the plug rod 82 can be slid out from the slot 81. Then, the handle 5 can be moved horizontally to pull the handle 5 out from the connecting sleeve 4. Then, push the plug rod 82 back to insert the plug rod 82 into the slot 81 in another position. This allows the relative length of the handle 5 and the connecting sleeve 4 to be easily adjusted. The length of the handle 5 can be adjusted according to the needs.

[0022] The motor 7 drives the winding reel 10 to rotate, enabling the winding and unwinding of the conductor. As the winding reel 10 rotates, it moves along the limit seat 93. The arc surface of the slot 91 inside the winding reel 10 presses and pushes the retaining ball 92, which in turn pushes the support block 94 downwards. The support block 94 then moves the guide rod 95 downwards and presses down the second spring 96, ultimately separating the retaining ball 92 from the slot 91. With the rotation of the winding reel 10, the elasticity of the second spring 96 provides an upward counterforce to the support block 94, pushing the retaining ball 92 into another slot 91. This engagement of the retaining ball 92 with the slot 91 inside the winding reel 10 limits the winding reel 10 in a stationary state, preventing the reel 10 from rotating arbitrarily when the motor 7 is stopped, thus avoiding any issues with conductor winding and unwinding.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
