Technical Field

[0001] This utility model relates to the field of magnet magnetic force detection technology, specifically a device for assembling magnet magnetic force detection. Background Technology

[0002] Assembled magnets refer to the combination of multiple individual magnetic elements or related components in a certain way to form a magnetic assembly with a specific shape, structure or function. Due to the special shape of assembled magnets, a lightweight and convenient handheld magnetic force detector is usually used for magnetic force testing. However, the testing pen on the traditional handheld magnetic force detector needs to be stored and protected by inserting the pen cap when not in use, and the pen cap needs to be removed and stored when in use. Since the pen cap is an independent part, it is easy to lose, which means that the testing pen is easily damaged without the protection of the pen cap. In view of the above situation, we will carry out technical innovation on the basis of existing magnetic force testing devices for assembled magnets. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4A magnetic force testing device for assembling magnets includes a handheld magnetic force tester 1. The handheld magnetic force tester 1 is a relatively mature magnetic force testing device, and its working principle will not be elaborated here. A concave frame 11 is fixedly installed on the top of the handheld magnetic force tester 1. A cover plate 13 is slidably installed on the right side of the top of the concave frame 11. A testing pen 12 and a ballpoint pen 18 are respectively placed on the left and right sides of the top of the cover plate 13. A set of support plates 15 are installed on the opposite sides of the testing pen 12 and the ballpoint pen 18. A support shaft 22 is fixedly installed between the two sets of support plates 15. A rotating tube 2 is rotatably sleeved on the outer ring of the support shaft 22. A torsion spring 23 is fixedly installed between the rotating tube 2 and the support shaft 22. A pressure frame 21 is fixedly installed on the front side of the rotating tube 2. The two sets of support plates 15 are... A detection pen cap 16 and a ballpoint pen cap 17 are fixedly installed on the back side. The detection head of the detection pen 12 is inserted into the detection pen cap 16, and the writing head of the ballpoint pen 18 is inserted into the ballpoint pen cap 17. Two sets of support plates 15 are evenly fixed on the top left and right sides of the cover plate 13. Two sets of L-shaped reinforcing rods 14 are evenly fixed on the right side of the cover plate 13. Two sets of guide holes are evenly opened on the right side of the handheld magnetic detector 1. The end of the L-shaped reinforcing rod 14 away from the cover plate 13 is inserted into the guide hole. Pulling the pressure frame 21 upward causes the rotating tube 2 to rotate on the outer ring of the support shaft 22. At this time, the rotating tube 2 will drive the torsion spring 23 to twist. Then, the recording paper is placed on the cover plate 13 and positioned below the pressure frame 21. Then, the pressure frame 21 is released. At this time, the rebound force of the torsion spring 23 drives the pressure frame 21 to flip downward through the rotating tube 2, pressing the recording paper onto the cover plate 13. Then, the ballpoint pen 18 is pulled out from the pen cap 17. At this time, the detected magnetic data can be recorded on the recording paper by the ballpoint pen 18. The cover plate 13 is supported by the L-shaped reinforcing rod 14, so that the user can stably record data on the recording paper on the cover plate 13. When the cover plate 13 slides to the left, the cover plate 13 will drive the L-shaped reinforcing rod 14 to slide in the guide hole, thereby assisting the cover plate 13 to move stably. The top of the concave frame 11 is evenly provided with two sets of convex sliding grooves. The convex sliding grooves are provided with a second positioning hole 115 and a first positioning hole 114. The second positioning hole 115 is located at the first positioning hole 114. Two sets of convex blocks 111 are evenly fixedly arranged on the left side of the positioning hole 114 and the bottom left side of the cover plate 13. The cover plate 13 corresponds to the display screen and buttons on the top of the handheld magnetic force detector 1. The detection pen 12 is electrically connected to the handheld magnetic force detector 1. The bottom of the convex block 111 has a mounting hole, and a spring 113 is fixedly installed in the mounting hole. A round-headed pin 112 is fixedly installed at the bottom of the spring 113. When the spring 113 drives the round-headed pin 112 to insert into the first positioning hole 114, the convex block 111 is stabilized in the convex groove of the concave frame 11. At this time, the cover plate 13 is located on the top right side of the concave frame 11. Then, when the detection pen 12 is pulled out from the detection pen cap 16, the detection pen 12 can be used to perform magnetic force detection on the assembled magnet.The magnetic force value is then displayed using a handheld magnetic force detector 1. The convex block 111 is slidably positioned within the convex groove, and the rounded end of the rounded pin 112 is inserted into the first positioning hole 114, corresponding to the second positioning hole 115.

[0021] Working principle: When the spring 113 drives the round-headed pin 112 to insert into the first positioning hole 114, the convex block 111 is stabilized in the convex groove of the concave frame 11. At this time, the cover plate 13 is located on the top right side of the concave frame 11. Then, when the detection pen 12 is pulled out from the pen cap 16, the magnetic force of the assembled magnet can be detected by the detection pen 12. Then, the magnetic force value is displayed by the handheld magnetic force detector 1. Pull the pressure frame 21 upward to drive the rotating tube 2 to rotate on the outer ring of the support shaft 22. At this time, the rotating tube 2 will drive the torsion spring 23 to twist. Then, place the recording paper on the cover plate 13 and make it below the pressure frame 21. Then release the pressure frame 21. At this time, the rebound force of the torsion spring 23 drives the pressure frame 21 to flip downward through the rotating tube 2 to press the recording paper tightly on the cover plate 13. Then, pull the ballpoint pen 18 out from the pen cap 17. At this time, the detected magnetic force data can be recorded on the recording paper by the ballpoint pen 18.

[0022] When the device is not in use, insert the test pen 12 back into the test pen cap 16, and insert the ballpoint pen 18 back into the ballpoint pen cap 17. Then, push the cover plate 13 to the left through the ballpoint pen cap 17. The cover plate 13 drives the convex block 111 to move synchronously to the left. When the spring 113 drives the round-headed pin 112 to insert into the second positioning hole 115, the cover plate 13 is located directly above the display screen and buttons of the handheld magnetic force detector 1. In this way, the cover plate 13 protects the display screen and buttons of the handheld magnetic force detector 1 from dust and collision. Similarly, when the handheld magnetic force detector 1 needs to be used, the cover plate 13 can be slid to the right by pushing the test pen cap 16 to the right, so that the cover plate 13 is misaligned with the display screen and buttons of the handheld magnetic force detector 1.

[0023] The cover plate 13 is supported by the L-shaped reinforcing rod 14, which ensures that the user can stably record data on the recording paper on the cover plate 13. When the cover plate 13 slides to the left, the cover plate 13 will drive the L-shaped reinforcing rod 14 to slide in the guide hole, thereby assisting the cover plate 13 to move stably.
