Description

Technical Field

[0001] This utility model relates to the field of magnets, and in particular to a pull-out magnet. Background Technology

[0002] Pull-out magnets are devices that use magnetism to attract ferromagnetic materials. They are mainly used in factories, workshops, or construction sites to conveniently and safely pick up and move scattered nails, screws, iron filings, or other small iron parts, avoiding contact with bare hands.

[0003] The pull-out magnet in related technologies typically includes an upper housing, a lower housing, a strong magnet, a support tube, and a pull rod. The lower housing is welded and fixed to the bottom of the upper housing. The strong magnet is slidably disposed inside the upper and lower housings. The support tube is fixed to the top of the upper housing. The pull rod is slidably disposed inside the support tube and is fixedly connected to the strong magnet.

[0004] In related technologies, the lower housing is typically made of iron. Pushing the pull rod causes a strong magnet to move downwards. When the magnet enters the lower housing, it becomes magnetic and can attract parts such as nails. Pulling the pull rod causes the magnet to move upwards. When the magnet enters the upper housing, the magnetism of the lower housing disappears, and the nails and other parts fall off.

[0005] However, in the relevant technology, the lower housing is welded and fixed to the upper housing, and the lower housing cannot be replaced. After the lower housing is rubbed against a strong magnet for a long time, the lower housing will become magnetic. That is, even after the strong magnet enters the upper housing, the lower housing can still attract parts such as iron nails, and the iron nails and other parts cannot be removed, thus affecting the use effect of the pull-out magnet and needs to be improved. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pull-out magnet with a removable and replaceable lower housing that ensures the lower housing is in a non-magnetic state, allowing parts such as nails to fall off smoothly, thereby ensuring the effectiveness of the pull-out magnet.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pull-out magnet, comprising an upper shell, a lower shell, a strong magnet, a support tube and a pull rod, wherein a support ring is fixedly connected to the bottom port of the upper shell, and an mounting ring is fixedly connected to the top port of the lower shell, and the support ring and the mounting ring are detachably connected by bolts.

[0008] Optionally: the bolt portion includes a plurality of bolt posts respectively fixed on the mounting ring, the support ring is provided with a plurality of support holes, the plurality of bolt posts respectively pass through the corresponding support holes, and a locking nut is threaded onto each of the plurality of bolt posts.

[0009] Optionally, an elastic sealing ring is fixedly connected to the mounting ring, and a sealing groove is provided on the support ring for the sealing ring to be tightly engaged.

[0010] Optionally, the support tube and the pull rod are provided with limiting components. When the strong magnet is fully inserted into the upper housing, the limiting components are used to fix the pull rod.

[0011] Optionally, the limiting component includes a limiting screw threaded onto the support tube, and the pull rod is provided with a limiting groove for the limiting screw to engage with the thread.

[0012] Optionally, a non-slip grip is fixedly connected to the top of the pull rod.

[0013] Optionally, a suspension ring is fixedly connected to the top of the anti-slip grip.

[0014] In summary, this utility model has the following beneficial effects: 1. By setting a removable and replaceable lower housing, the lower housing can be replaced after it becomes magnetized, ensuring that the lower housing is in a non-magnetic state. When the pull rod is pulled to move the strong magnet upward, parts such as nails can be easily dislodged, thus ensuring the effectiveness of the pull-out magnet. 2. The pull rod is fixed by a limiting component. When the magnet is stored, it ensures that the strong magnet is separated from the lower housing, reducing the risk of the lower housing being magnetized by the strong magnet and thus improving the service life of the magnet.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figure 1 , Figure 2A pull-out magnet includes an upper housing 1, a lower housing 2, a strong magnet 3, a support tube 4, and a pull rod 5. The ports of the upper housing 1 and the lower housing 2 are arranged opposite each other, and the strong magnet 3 is slidably disposed within the upper housing 1 and the lower housing 2. The support tube 4 is fixed to the top of the upper housing 1, and the pull rod 5 is slidably disposed within the support tube 4 and is fixedly connected to the strong magnet 3.

[0019] Reference Figure 2 , Figure 3 A support ring 6 is fixedly connected to the bottom port of the upper housing 1, and a mounting ring 7 is fixedly connected to the top port of the lower housing 2. The support ring 6 and the mounting ring 7 are detachably connected by bolts 8 so that the lower housing 2 can be disassembled and replaced.

[0020] Once the lower housing 2 is magnetized, it can be replaced to ensure that the lower housing 2 is in a non-magnetic state. When the pull rod 5 is pulled to drive the strong magnet 3 upward, parts such as nails can be easily dislodged, thus ensuring the effectiveness of the pull-out magnet.

[0021] Reference Figure 2 , Figure 3 The bolt part 8 includes multiple bolt posts 81 that are vertically fixed on the mounting ring 7. The support ring 6 is provided with multiple support holes 9. The multiple bolt posts 81 pass through the corresponding support holes 9, and each of the multiple bolt posts 81 is threaded with a locking nut 82. That is, the mounting ring 7 and the support ring 6 are pressed and fixed by the locking nut 82, thereby realizing the connection between the upper housing 1 and the lower housing 2.

[0022] Reference Figure 2 , Figure 3 An elastic sealing ring 10 is fixedly connected to the mounting ring 7, and a sealing groove 11 is provided on the support ring 6 for the sealing ring 10 to be tightly engaged, so as to improve the sealing effect between the upper housing 1 and the lower housing 2, reduce the risk of debris entering the interior of the upper housing 1 and the lower housing 2, and thus reduce the risk of the strong magnet 3 becoming dirty. In this embodiment, the sealing ring 10 is made of elastic materials such as rubber, latex or silicone.

[0023] Reference Figure 1 , Figure 2 Limiting elements 12 are provided on the support tube 4 and the pull rod 5. When the strong magnet 3 is fully inserted into the upper housing 1, the limiting elements 12 are used to fix the pull rod 5. This design allows the strong magnet 3 to separate from the lower housing 2 when the magnet is stored, reducing the risk of the lower housing 2 being magnetized by the strong magnet 3, thereby improving the service life of the magnet.

[0024] Reference Figure 1 , Figure 2The limiting component 12 includes a limiting screw 121 threaded onto the support tube 4, and a limiting groove 122 provided on the pull rod 5 for the limiting screw 121 to engage with the thread. When the top of the strong magnet 3 abuts against the top side wall of the upper housing 1, the strong magnet 3 is fully inserted into the upper housing 1. At this time, the limiting screw 121 and the limiting groove 122 are aligned. Tightening the limiting screw 121 will fix the pull rod 5.

[0025] Reference Figure 1 , Figure 2 The top of the pull rod 5 is fixedly connected to a non-slip handle 13 to reduce the risk of slipping on the operator's hands and facilitate the pull-out operation. At the same time, a hanging ring 14 is fixedly connected to the top of the non-slip handle 13 so that the magnet can be hung and stored.
