Fig. 1 and 2 show an embodiment of a straight needle ear ring for preventing falling off, which comprises a facing 20 and an ear needle 10, wherein the ear needle 10 is fixedly connected to the facing 20, the size of the ear needle 10 is not larger than that of an ear hole in order to enable the ear needle 10 to pass through the ear hole, and the ear needle 10 has different specifications because the sizes of the ear holes are not unified; the shape, pattern and material of the facing 20 are different from earring to earring, and thus the present invention does not limit the shape, pattern and material of the facing 20. The ear needle 10 comprises a perforated cylinder 100 and an expansion bolt 200, the head end of the perforated cylinder 100 is fixedly connected with the facing 20, the tail end of the perforated cylinder 100 is provided with a plurality of expansion pieces 310, and the perforated cylinder 100 and the expansion pieces 310 are integrally formed; in order to process the plurality of expansion pieces 310, firstly, the end of the through hole cylinder 100 needs to be processed into a circular cylinder 300, then a cutting process is adopted to divide the circular cylinder 300 and generate the plurality of expansion pieces 310, two adjacent expansion pieces 310 are arranged at intervals, finally, the circular cylinder 300 is provided with a plurality of open grooves 320, and the circular cylinder 300 has an outward expansion function. A threaded hole 110 is processed in the through hole cylinder 100, the threaded hole 110 is communicated with the circular cylinder 300, and the nominal diameter of the threaded hole 110 is smaller than the inner diameter of the circular cylinder 300.
As shown in fig. 3, the expansion bolt 200 includes a screw portion 210, an expansion portion 220, a straight rod portion 230, and a head portion 240 connected in sequence, the screw portion 210, the expansion portion 220, the straight rod portion 230, and the head portion 240 are integrally formed, a maximum size of the expansion portion 220 is larger than an inner diameter of the circular cylinder 300, and the screw portion 210 is in threaded connection with the threaded hole 110; in order to allow the ear pin 10 to smoothly pass through the ear hole, the maximum size of the expansion bolt 200 is not greater than the diameter of the piercing cylinder 100. Specifically, the shape of the expansion portion 220 is a truncated cone, the diameter of the front side surface of the expansion portion 220 is smaller than the diameter of the rear side surface of the expansion portion 220, and the rear side surface of the expansion portion 220 is fixedly connected with the straight rod portion 230, that is, the front side surface of the expansion portion 220 points to the circular cylinder 300; in order to enable the expansion portion 220 to better expand the circular ring cylinder 300, the diameter of the front side surface of the expansion portion 220 is not larger than the inner diameter of the circular ring cylinder 300, because the expansion portion 220 has an inclined surface, as the screw portion 210 gradually moves forward in the threaded hole 110, the expansion portion 220 also moves forward, the expansion portion 220 abuts against the expansion pieces 310 and gradually expands the circular ring cylinder 300, so that the outer dimension of the circular ring cylinder 300 is gradually increased, and when the outer dimension of the circular ring cylinder 300 is larger than the dimension of an ear hole, even if a user does strenuous exercise, the expansion portion does not easily fall off from the ear hole. On the contrary, when the user needs to remove the present invention, the user only needs to drive the screw portion 210 to move backward in the threaded hole 110, and the expansion portion 220 also moves backward, so that the outer dimension of the circular cylinder 300 is gradually restored, and when the outer dimension of the circular cylinder 300 is completely restored, the user can directly remove the present invention.
In addition, even if the user removes the present invention, the expansion bolt 200 is not separated from the through-hole cylinder 100, that is, after the outer dimension of the circular ring cylinder 300 is completely restored, the screw portion 210 is screwed into the threaded hole 110, and the user should avoid unscrewing the expansion bolt 200 as much as possible to prevent the expansion bolt 200 from being lost.
In other embodiments, as shown in fig. 2, in order to increase the friction coefficient of the head 240 and facilitate the screwing of the head 240, a knurl 241 is provided on the outer circumference of the head 240.
It should be further noted that, since the ear needle 10 is in contact with the ear hole, in order to prevent inflammation of the ear hole, the ear needle 10 is made of silver metal, gold metal, platinum metal or titanium alloy, but since the silver metal, gold metal or platinum metal has poor elasticity and is not beneficial to the restoration of the circular ring cylinder 300, the ear needle 10 is preferably made of titanium alloy.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
