Detailed Description

Referring to fig. 1 to 4 in combination, according to an embodiment of the present invention, an ear nail seat mounting structure includes a body, two cavities that are connected are provided in the body: a sphere cavity 4 and a receiving cavity 5; the ear nail seat is stressed in the ball cavity 4 to extrude the conduction channels of the two cavities, so that the conduction channels are expanded until the ear nail seat is separated from the ball cavity 4 and enters the accommodating cavity 5.

The ear stud seat mounting structure has certain elasticity, and particularly has elastic retraction performance due to the conduction channels of the two cavities; the spherical cavity is used for stabilizing the spherical ear nail seat 2, so that the ear nail is conveniently aligned and inserted into the ear nail seat; and further promote the ear nail seat and extrude into accommodating cavity 5 completely after inserting, the passageway that switches on makes the ear nail seat remain in accommodating cavity 5 because elastic retraction this moment, makes things convenient for subsequent taking out.

Wherein, in order to put in or take out the installation structure by the ear nail seat, the top surface of the ball cavity 4 and/or the top surface of the containing cavity 5 are/is arranged to be open structure. The top surfaces of the two cavities are opened, the ear nail seat is firstly placed in the ball cavity 4, and the ear nail seat is inserted into the containing cavity 5 and then extruded to be conducted, so that the ear nail seat can be conveniently taken out from the top of the containing cavity 5.

The mounting structure can adopt elastic materials such as plastics to make, for the elasticity that further improves two cavitys, makes things convenient for the ear nail seat to establish steadily in spheroid cavity 4 to and hold cavity 5 by leading to the passageway can be crowded into, establish the lateral wall of spheroid cavity 4 into partial unsettled, and/or the lateral wall that holds cavity 5 establishes into partial unsettled. In particular, the side walls of the through channels are suspended, e.g. the bottom 18 of the two cavities is spaced from the bottom 18 of the body.

Wherein, in order to improve the stability of the ear nail seat in the sphere cavity 4, the shape of the sphere cavity 4 is matched with the shape of the ear nail seat. The ear stud seat shown in fig. 1 is a spherical structure, and comprises a sphere 22, wherein the sphere 22 corresponds to a spherical inner cavity, and the inner diameter of the spherical inner cavity is the same as the outer diameter of the sphere 22; or when the ring wing 21 is arranged on the sphere 22, the cavity 4 of the sphere is provided with a matched through groove.

The volume that holds cavity 5 and be greater than spherical ear nail seat 2 holds in holding cavity 5, and spherical ear nail seat 2 can freely move about, inserts spherical ear nail seat 2 to the complete crowded ear nail structure who holds cavity 5 back of holding of spherical ear nail seat 2 at ear nail 3, conveniently takes out the combination. Specifically, the receiving cavity 5 may be a square cavity or another shape that facilitates the removal of the spherical ear stud receptacle 2.

The specific structure of the mounting structure of the ear nail seat is described as follows:

the main body is a plastic mounting structure 1 comprising two cavities that can be formed by a front wall 11 with a circular through hole 15, a first side wall 12, a second side wall 13, a rear wall 14 and a bottom 18: a sphere cavity 4 and a receiving cavity 5, the top surfaces of which are open, as shown in fig. 2 and 3.

The front wall 11 as described above has a circular through hole 15, and the through hole 15 has a notch 16 with a width slightly smaller than the diameter of the ring wing 21 of the spherical ear nail seat 2, so that the ring wing 21 of the spherical ear nail seat 2 can be squeezed into the circular through hole 15 through the notch 16 and fix the spherical ear nail seat 2, as shown in fig. 2 and 3.

The sphere cavity 4 and the receiving cavity 5 are connected by a neck gap 17 with a reduced width, the width of the neck gap 17 being smaller than the diameter of the sphere 22. Due to the plastic deformability of the first side wall 12 and the second side wall 13, the ball 22 can be pushed through the neck recess 17 by the thrust of the shank 31 of the stud 3, from the ball cavity 4 into the receiving cavity 5, as shown in fig. 4. To increase the amount of elastic deformation of the first and

second sidewalls

12 and 13, the bottom portions of the first and

second sidewalls

12 and 13 are partially suspended.

After the spherical ear stud seat 2 is squeezed through the neck gap 17, the width of the neck gap 17 is rebounded to be smaller than the diameter of the sphere 22 of the ear stud seat 2 due to plastic rebounding, so that the situation that the ear stud seat 2 accidentally retreats and then the ring wing 21 of the ear stud seat 2 retreats to the through hole 15 is avoided, and the ear stud seat 2 and the ear stud 3 penetrating through the ear stud seat can be separated from the plastic mounting structure 1 together, as shown in fig. 3 and 4.

The working principle is as follows: when the needle rod 31 of the ear nail 3 pierces the spherical ear nail seat 2, the spherical ear nail seat 2 is pushed to move backwards, the ring wing 21 is separated from the through hole 15, and the sphere 22 of the ear nail seat extrudes through the neck gap 17 and enters the accommodating cavity 5 from the sphere cavity 4. Since the size of the receiving cavity 5 is significantly larger than that of the ear nail seat ball 22, the ring wing 21 is also separated from the fixation of the circular through hole 15, and the ear nail 3 and the spherical ear nail seat 2 can be easily separated from the plastic mounting structure 1, as shown in fig. 3 and 4.

The mounting structure of the spherical ear nail seat can be applied to ear hole punching devices in various mechanism forms and used for fixing and releasing the spherical ear nail seat 2.

Referring to fig. 5 to 7 in combination, according to an embodiment of the present invention, an ear hole punching device includes the above-mentioned mounting structure of the ear nail seat.

The ear hole punching device comprises a spherical ear nail seat, the spherical ear nail seat comprises an ear nail seat ball body and a ring wing as shown in figure 1, and the ring wing is fixed on the ear nail seat ball body. Correspondingly, the width of the upper part of the through groove of the spherical cavity is set to be smaller than the outer diameter of the ring wing; and the ring wing is extruded into the through groove along the upper part of the through groove when the ear hole is punched.

The L-shaped earhole punching device shown in fig. 5 and fig. 6 mainly comprises a cavity body 201, a piston body 202, a spring 203, an ear nail cartridge 204, an ear nail 205, a guide rail 206, and the like. The cavity body 201 is a structure including two cavities, and a guide rail 206 is provided in the upper cavity, and the ear stud 204 is clamped on the guide rail 206 and can move on the guide rail 206. The cavity body 201 slides on the piston body 202, a spring 203 is arranged between the cavity body and the piston body 202, and the other end of the piston body 202 is fixedly connected with the plastic mounting structure 1. Pushing the cavity body 201 compresses the spring so that the ear stud cartridge 204 is adjacent to the plastic mounting structure 1. The ear stud 205 is placed in the stud cartridge 204 and can interact with a spherical stud receptacle 2 which is snapped into the spherical cavity 4 of the plastic mounting structure 1.

When the cavity body 201 and the piston body 202 are pinched together by hand, the spring 203 contracts and the ear pin 205 penetrates through the earlobe and pierces the spherical ear pin holder 2, as shown in fig. 7. When the ear stud 102 pierces the spherical ear stud receptacle 2, the spherical ear stud receptacle 2 is pushed to move backwards, the ring wings 21 disengage from the through-holes 15, and the ball 22 of the ear stud receptacle pushes through the neck recess 17 and enters the receiving cavity 5 from the spherical cavity 4. Since the size of the receiving cavity 5 is significantly larger than the ear nail seat sphere 22, the ring wing 21 is also separated from the fixation of the circular through hole 15, and the ear nail 3 and the spherical ear nail seat 2 can be easily separated from the plastic mounting structure 1.

It is easily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention. 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 should also be regarded as the protection scope of the present invention.
