Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The present invention will be described below with reference to fig. 1 to 3.

A plastic strip with soft magnetic strips comprises rubber soft magnetic strips 1 and a plastic sleeve 2, wherein magnetic strip mounting holes 3 are formed in one side of the plastic sleeve 2, and the rubber soft magnetic strips 1 are located in the magnetic strip mounting holes 3. The upper surface and the lower surface of the plastic sleeve 2 are provided with anti-skid grains 11. The anti-slip threads 11 enable the plastic sleeve 2 to have a better hand feeling, so that a user can better use the plastic strips, and in addition, the anti-slip threads 11 enable the user to better grasp the plastic sleeve 2 when the rubber soft magnetic strips 1 are pulled out of the plastic sleeve 2. The cross section of the rubber soft magnetic strip 1 is rectangular, and UV gloss oil layers 4 are coated on the upper surface and the lower surface of the rubber soft magnetic strip 1. The UV gloss oil layer 4 can harden the surface of the soft rubber magnetic strip 1 and make the surface smoother, on one hand, the scratch resistance of the soft rubber magnetic strip is improved, and on the other hand, the friction between the surface of the soft rubber magnetic strip 1 and the inner wall of the plastic sleeve 2 can be reduced, so that the soft rubber magnetic strip 1 can be more conveniently inserted into the plastic sleeve 2 or taken out of the plastic sleeve 2. In addition, the UV gloss oil layer 4 has a certain effect on blocking ultraviolet light and short-wavelength visible light, and can slow down the aging of the rubber soft magnetic strip 1. The side surfaces, close to the openings at the two ends of the magnetic stripe mounting hole 3, of the rubber soft magnetic stripe 1 are provided with arc-shaped grooves 8 which are symmetrical up and down, and a protrusion 9 is formed between the upper arc-shaped groove 8 and the lower arc-shaped groove 8. When the user needs to replace the plastic sleeve 2, the user can pinch the bulge 9 with the thumb and the forefinger to pull the soft rubber magnetic strip 1 out a little from the plastic sleeve 2, and then the user can take the soft rubber magnetic strip 1 out of the plastic sleeve 2 more easily on the basis.

The both ends opening part of magnetic stripe mounting hole 3 is provided with end cover 10, and end cover 10 can play dustproof and guard action, prevents to have impurity to enter into in the gap between rubber soft magnetic strip 1 and the magnetic stripe mounting hole 3 and lead to blockking up, influences the user and takes out rubber soft magnetic strip 1 from moulding set 2. The inner wall of the end cover 10 is provided with a magnetic block, when the end cover 10 covers the end part of the plastic sleeve 2, the magnetic block in the end cover 10 and the end part of the soft rubber magnetic strip 1 in the plastic sleeve 2 are mutually attracted, so that the situation that the end cover 10 slides off the plastic sleeve 2 is prevented.

The middle positions of the inner walls of the two sides of the magnetic stripe mounting hole 3 are provided with convex strips 5, and the cross section of each convex strip 5 is in an isosceles trapezoid shape. The length direction of sand grip 5 and magnetic stripe mounting hole 3 is parallel, and the length of sand grip 5 and the length of magnetic stripe mounting hole 3 are equal. The middle positions of the outer walls of the two sides of the rubber soft magnetic strip 1 are provided with guide grooves 6, and the cross sections of the guide grooves 6 are rectangular. One side of going to the bottom of sand grip 5 and the inner wall fixed connection of magnetic stripe mounting hole 3, the last end one side of sand grip 5 is located guide way 6. When the soft magnetic strip of rubber 1 reinserted and moulded cover 2 or taken out from moulding cover 2, sand grip 5 slides in guide groove 6, play the guide effect, soft magnetic strip of rubber 1 can remove along the length direction of magnetic stripe mounting hole 3 better, in the time of preventing that soft magnetic strip of rubber 1 from removing towards oblique top or oblique below, and increased the friction between soft magnetic strip 1 upper and lower surface and magnetic stripe mounting hole 3, lead to it to be difficult for removing. The upper and lower edges of the guide groove 6 close to one side of the convex strip 5 are provided with arc chamfers 7, the outer wall of the convex strip 5 cannot be scraped when the rubber soft magnetic strip 1 moves in the magnetic strip mounting hole 3 when the arc chamfers 7 can move, and friction between the upper and lower edges when the rubber soft magnetic strip moves is reduced. Gaps are reserved between the outer walls of the two sides of the rubber soft magnetic strip 1 and the inner walls of the two sides of the magnetic strip mounting hole 3, and the size of each gap is 0.3-0.6 mm. The rubber soft magnetic strip 1 can produce the hot phenomenon that rises when receiving tai sunshine and shining, and the clearance can provide certain space for the expansion of rubber soft magnetic strip 1, prevents that the expansion of rubber soft magnetic strip 1 back and the inner wall of magnetic stripe mounting hole 3 from closely laminating and be difficult for removing.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations of the above assumption should also be regarded as the protection scope of the present invention.
