Detailed Description

The utility model is further described below with reference to specific examples:

an anti-rotation magnetic bar is shown in figures 1-3 and comprises a bar rod 1, wherein the bar rod 1 is in a long strip shape, the shape of the bar rod 1 can be designed according to actual modeling requirements, and different shapes can achieve different appearance attraction effects. The two ends of the rod 1 are provided with rod heads 2, magnetic parts 4 are arranged in the rod heads 2, and the top of the rod heads 2 is provided with a butting surface 21 for contact.

In particular, the magnetic bar is composed of two half shells 11 as shown in fig. 2, and for saving materials, an inner cavity is arranged in each half shell 11 to form a frame-shaped part; the two half shells 11 are oppositely connected through the openings on the half shells 11 to form a magnetic rod with a hollow interior; the half shells 11 in the utility model are mostly made of plastic materials, and the half shells 11 are fixedly connected by welding or glue.

The front end and the rear end of the half shell 11 are provided with accommodating grooves 12, the accommodating grooves 12 are integrally formed in the half shell 11, and when the two half shells 11 are oppositely connected to form the rod bar 1, the notches of the two accommodating grooves 12 are oppositely connected to form an accommodating cavity for placing the magnetic element 4. As shown in fig. 2, the holding grooves 12 are hemispherical, a spherical holding cavity is formed by the connection structure of the two holding grooves 12, in this embodiment, the magnetic member 4 is a circular magnetic sheet with a diameter equivalent to that of the holding cavity, and when the magnetic rod is driven to approach an external magnetic object, the circular magnetic sheet can be turned in the holding cavity to make the magnetic poles of the circular magnetic sheet different from the magnetic poles of the external magnetic object, so as to perform adsorption.

Furthermore, be equipped with on the club head 2 and prevent the face of changeing, it includes that a plurality of rings are established to prevent the face of changeing 2 week sides of club head to end connection's inclined plane 22 in proper order. As shown in fig. 1, the rotation preventing surface is provided between the contact surface 21 and the outer surface of the rod 1 and connects the contact surface 21 and the outer surface of the rod 1, and since the area of the contact surface 21 is smaller than the cross-sectional area of the rod 1, the rotation preventing surface needs to be provided obliquely, and the entire rod head 2 is tapered. In this embodiment, the abutting surface 21 is formed by connecting and surrounding eight inclined planes 22 with the same area and size end to end, when two anti-rotation magnetic rods are fixed on the same sphere 3 at the same time, the abutting surface 21 of the anti-rotation magnetic rod abuts against the spherical surface of the sphere 3, and on the sphere 3, the inclined planes 22 on two adjacent anti-rotation magnetic rods abut against each other; because the part that the butt between two magnetic force stick is the plane, can not lead to between the magnetic force stick to support unstablely because the part of butt is the cambered surface between the magnetic force stick to influence the molding of magnetic force stick, through the stability of the magnetic force stick installation that inclined plane 22 comes greatly increased. The number and size of the inclined planes 22 can be set according to the actual modeling requirements, for example, six or four inclined planes can be set, and each inclined plane can realize the function of increasing the stability of the installation of the magnetic rods; the inclined planes 22 with the same area can ensure that the butt joint between the magnetic rods is more stable when the magnetic rods are butted, and the area of each inclined plane 22 is set to be the same, so that the orientation of the magnetic rods does not need to be adjusted intentionally, and the assembly of the magnetic rods is easier.
