Description

Technical fields:

[0001] This utility model relates to the field of magnet technology, and in particular to a ring magnet that is easy to install. Background technology:

[0002] Some modular splicing products, such as modular splicing light tubes, use magnetic docking for splicing. This involves attaching magnets to the ends of two adjacent light tube modules to attract and connect them.

[0003] To facilitate the passage and docking of connecting wires between modules, magnets are generally designed in a ring shape. Existing common ring magnets are often fixed by direct bonding, that is, the end that is not magnetically connected is directly glued to the end of the product, and then the other end is magnetically connected to the end of another magnet. However, this method of installation not only has the risk of magnets falling off and affecting normal use, but also the polarity of the end of the magnet used for attraction cannot be changed, which has certain limitations in use. Utility Model Content:

[0004] The purpose of this invention is to provide an easy-to-install ring magnet to address the shortcomings of existing technologies. It is not only easy to install and more secure, eliminating the risk of falling off, but also allows for the reversal of the polarity of the end of the magnet used for attraction, making it more flexible and practical.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ring-shaped magnet that is easy to install, comprising a magnet body with a ring structure, wherein an installation post is inserted into the inner ring of the magnet body along the vertical direction, and the installation post has a plurality of first-step installation holes and a plurality of second-step installation holes. Each first-step installation hole includes a first through hole located at the bottom of the installation post and a first countersunk hole located at the top of the installation post in a concentric and proportionally enlarged manner and connected to the first through hole. Each second-step installation hole includes a second through hole located at the top of the installation post and a second countersunk hole located at the bottom of the installation post in a concentric and proportionally enlarged manner and connected to the second through hole.

[0006] A further improvement to the above scheme is that there are multiple first-step mounting holes, which are evenly distributed along the circumferential direction of the mounting column; and there are multiple second-step mounting holes, which are evenly distributed along the circumferential direction of the mounting column.

[0007] A further improvement to the above solution is that a wiring hole is provided in the middle of the mounting column.

[0008] A further improvement to the above scheme is that the mounting post is made of a non-magnetic material.

[0009] A further improvement to the above scheme is that the outer periphery of the mounting post extends outward to form multiple mounting protrusions, and the inner ring of the magnet body is recessed inward to provide multiple mounting grooves for cooperating with the mounting protrusions, with each mounting protrusion respectively engaging in each mounting groove.

[0010] A further improvement to the above scheme is that the cross-sectional shape of the mounting protrusion is an isosceles trapezoid.

[0011] A further improvement to the above scheme is that the top of the mounting post is provided with an N pole marking section, and the bottom of the mounting post is provided with an S pole marking section.

[0012] A further improvement to the above scheme is that the first through hole, the first countersunk hole, the second through hole, and the second countersunk hole are all waist-shaped hole structures.

[0013] A further improvement to the above scheme is that the length directions of the first through hole, the first countersunk hole, the second through hole, and the second countersunk hole are parallel to the radial direction of the mounting post.

[0014] A further improvement to the above scheme is that the thickness of the mounting post is less than or equal to the thickness of the magnet body.

[0015] The beneficial effects of this utility model are as follows: This utility model provides an easy-to-install ring magnet, including a magnet body with a ring structure. The inner ring of the magnet body is fitted with a mounting post along the vertical direction. The mounting post has a plurality of first-step mounting holes and a plurality of second-step mounting holes. Each first-step mounting hole includes a first through hole set at the bottom of the mounting post and a first countersunk hole set at the top of the mounting post in a concentric and proportionally enlarged manner and connected to the first through hole. Each second-step mounting hole includes a second through hole set at the top of the mounting post and a second countersunk hole set at the bottom of the mounting post in a concentric and proportionally enlarged manner and connected to the second through hole.

[0016] Compared to existing ordinary ring magnets that can only be fixed by adhesive bonding, this utility model integrates the mounting post and the magnet body into a single structure. Screws are passed through the first-step or second-step mounting holes and threaded onto the product to be installed. This allows the mounting post and magnet body to be installed on one end of the product, replacing the previous adhesive bonding method for fixing the ring magnet. This method is easier to install, more secure, and eliminates the risk of detachment. Furthermore, tightening the screws into the first-step mounting holes locks one end of the magnet body in place. Loosening the screws from the first-step mounting holes, flipping the magnet body over, and then tightening the screws into the second-step mounting holes locks the other end of the magnet body in place. This allows for polarity reversal at the attractive end of the magnet, offering greater flexibility and practicality. Attached image description:

Detailed implementation method:

[0020] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-2 As shown, this utility model includes a ring-shaped magnet body 1. An mounting post 2 is inserted into the inner ring of the magnet body 1 along the vertical direction. The mounting post 2 has several first-step mounting holes 21 and several second-step mounting holes 22. Each first-step mounting hole 21 includes a first through hole 211 located at the bottom of the mounting post 2 and a first countersunk hole 212 concentrically and proportionally enlarged at the top of the mounting post 2 and connected to the first through hole 211. Each second-step mounting hole 22 includes a second through hole 221 located at the top of the mounting post 2 and a second countersunk hole 222 concentrically and proportionally enlarged at the bottom of the mounting post 2 and connected to the second through hole 221. Compared to existing ordinary ring magnets that can only be fixed by adhesive bonding, this utility model inserts the mounting post 2 into the magnet body 1... The integrated structure allows screws to be threaded through the first-step mounting holes 21 or the second-step mounting holes 22 and connected to the product to be installed. This enables the mounting post 2 and the magnet body 1 to be installed on one end of the product, replacing the previous method of fixing the ring magnet with adhesive. This method is easier to install, more secure, and eliminates the risk of falling off. In addition, by tightening the screws into the first-step mounting holes 21, one end of the magnet body 1 can be locked in place. By loosening the screws from the first-step mounting holes 21, flipping the magnet body 1 over, and then tightening the screws into the second-step mounting holes 22, the other end of the magnet body 1 can be locked in place. This allows for polarity reversal of the magnet's attractive end, making it more flexible and practical.

[0021] The first through hole 211 in the first stepped mounting hole 21 and the second through hole 221 in the second stepped mounting hole 22 are for the threaded part of the screw to pass through. The first countersunk hole 212 in the first stepped mounting hole 21 and the second countersunk hole 222 in the second stepped mounting hole 22 are for accommodating the screw head, which can prevent the screw head from protruding from the outer surface of the mounting post 2. By hiding the screw head, the overall design is not only simpler and more beautiful, but also avoids affecting the subsequent magnetic attraction between the two magnet bodies 1. The two magnet bodies 1 can be better magnetically attracted and connected.

[0022] Compared to having only one first-step mounting hole 21 or one second-step mounting hole 22, this utility model has multiple first-step mounting holes 21 and multiple second-step mounting holes 22, which can realize the locking installation of multiple screws, making the overall connection more stable and reliable. The first-step mounting holes 21 and the second-step mounting holes 22 are evenly distributed along the circumferential direction of the mounting post 2, so that the screws are subjected to more uniform force, which can further ensure that the overall connection is more stable and reliable.

[0023] The mounting post 2 has a wiring hole 23 in the middle, which makes it easy to pass and connect wires, etc., and can be better suited for products such as modular splicing lamp tubes.

[0024] The mounting post 2 is made of non-magnetic materials such as plastic, which can better prevent the magnet body 1 from causing magnetic field interference to the connecting wires.

[0025] The outer periphery of the mounting post 2 extends outward to form multiple mounting protrusions 24. The inner ring of the magnet body 1 is recessed inward to form multiple mounting grooves 11 for cooperating with the mounting protrusions 24. Each mounting protrusion 24 is respectively engaged in each mounting groove 11. The cross-sectional shape of the mounting protrusion 24 is an isosceles trapezoid, making the connection between the mounting post 2 and the magnet body 1 more secure.

[0026] The top of the mounting post 2 is provided with an N pole marking part 3, and the bottom of the mounting post 2 is provided with an S pole marking part 4. The end of the mounting post 2 with the N pole marking part 3 is inserted into the end of the magnet body 1 near the N pole, and the end of the mounting post 2 with the S pole marking part 4 is inserted into the end of the magnet body 1 near the S pole. The N pole and S pole of the magnet body 1 can be quickly identified by the N pole marking part 3 and the S pole marking part 4 on the mounting post 2, so as to quickly and conveniently realize the magnetic attraction between the two magnet bodies, prevent incorrect installation, and improve the overall assembly efficiency.

[0027] The first through hole 211, the first countersunk hole 212, the second through hole 221, and the second countersunk hole 222 are all oblong hole structures. The length direction of the first through hole 211, the first countersunk hole 212, the second through hole 221, and the second countersunk hole 222 is parallel to the radial direction of the mounting post 2. The radial position of the screw on the mounting post 2 can be adjusted, which not only provides tolerance for the machining error of the threaded hole of the product to be installed, but also can be used to install threaded holes at different radius positions on the product to be installed, making it more flexible and practical.

[0028] The thickness of the mounting post 2 is less than or equal to the thickness of the magnet body 1, which enables better magnetic attraction between the two magnet bodies 1.

[0029] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
