Detailed Description
As shown in fig. 1-3, an easily detachable axle center device for nail art comprises an axle center body 1 and an end cap 2 sleeved on one end of the axle center body 1; the axle center body 1 is sequentially divided into a head part 1-1, a shaft shoulder part 1-2 and a connecting rod part 1-3 from left to right; the end cap 2 is coaxially sleeved on the head part 1-1, an inner cavity of the end cap 2 is in interference fit with the head part 1-1, an outer diameter D1 at the right end of the end cap 2 is larger than an outer diameter D2 at the left end, D1-D2 is 0.3 mm-0.7 mm, and preferably, D1-D2 is 0.5 mm.
In this embodiment, the length of the portion of the end cap 2 having an outer diameter D1 at the right end thereof is 1/5-1/4 of the total length of the end cap 2.
In this embodiment, the end cap 2 has a transition between the portion with the outer diameter D1 and the portion with the outer diameter D2 by a ramp 2-1, wherein the ramp 2-1 has a ramp angle of 8 ° to 45 °, preferably 12 °. The slope surface 2-1 is convenient for the sand ring to be sleeved on the end cap 2.
In this embodiment, a plurality of notches are formed in the side wall of the end cap 2 along the circumferential direction of the opening at the right end of the end cap 2. The inner diameter of the part of the end cap 2 where the gap is located is larger than the outer diameter of the head part 1-1. And a plurality of the gaps are uniformly distributed. The right-hand member of end cap 2 is a plurality of jack catchs 2-2 in the setting of opening, and in the in-service use, when the sand circle was established to the cover, jack catchs 2-2 can inwards contract, and the sand circle cover of being convenient for is established, and the existence of opening in addition can give the bigger frictional force of sand circle inner circle, can let end cap 2 give the stronger drive power of sand circle.
In this embodiment, the gap is a long strip, the length of the gap is 1/3-2/3 of the whole length of the end cap 2, and preferably, the length of the gap is 1/2 of the whole length of the end cap 2.
In this embodiment, a gap is provided between the right end of the end cap 2 and the shaft shoulder 1-2. The existence in clearance can conveniently pull down end cap 2, and all need heat earlier when the installation with dismantle in reality end cap 2 utilizes expend with heat and contract with cold principle, realizes the installation and dismantles.
In this embodiment, the outer surface of the portion of the end cap 2 having an outer diameter D1 at the right end thereof is roughened 2-3. The rough surface 2-3 can enable the sand ring to be arranged at the right end of the end cap 2, the friction force between the inner ring of the sand ring and the right end of the end cap 2 is larger, and the sand ring and the end cap 2 can rotate basically synchronously when in use.
In this embodiment, a limiting ring 4 is sleeved at the left end of the end cap 2, a sleeve 3 is coaxially sleeved on the end cap 2, and the sleeve 3 can move left and right between the limiting ring 4 and a part of the end cap 2 with an outer diameter D1 at the right end; the outer diameter of the sleeve 3 is smaller than the outer diameter D1 at the right end of the end cap 2; the limiting ring 4 is used for preventing the sleeve 3 from falling off.
It should be noted that, the arrangement of the limiting ring 4 and the sleeve 3 is to enable the emery ring to obtain a better grinding effect when the fingernail is ground. Specifically, because in practice, both ports of the sand ring are contraction ports, that is, the diameter of the port is smaller than the inner diameter of the sand ring; the limiting ring 4 is arranged, after the sand ring is sleeved on the end cap 2, the left end of the sand ring can be tightly hooped on the limiting ring 4, the sand ring is not easy to fall off, in addition, the sleeve 3 can be arranged to support part of the segments of the sand ring to a certain extent, if the segments of the sand ring close to the left end are completely supported by the end cap 2, the gap between the inner wall of the sand ring and the outer wall of the end cap 2 is too large, the sand ring cannot be supported enough, so that the problem of deformation of the sand ring after being polished for several times is easily caused, but if the outer diameter of the end cap 2 close to the left end is enlarged, the gap between the inner wall of the sand ring and the outer wall of the end cap 2 is reduced, after the sand ring is subjected to the reverse pressure of a nail, the sand ring cannot be effectively recessed, the rigid impact on the nail is large, a good polishing effect cannot be obtained, and by arranging the sleeve 3, the characteristic that the sleeve 3 moves left and right variably in the polishing process, the part of the sand ring corresponding to the sleeve 3 which is not effectively supported can be changed, can be unscheduled let the grit circle part position can effectual indent, reduce the rigidity and strike.
In practice, the sand ring part right opposite to the area between the limiting ring 4 and the left end of the sleeve 3 is a main grinding use area, when the sand ring is ground by using the area, if the reverse pressure of a nail is large, the sleeve 3 is forced to move rightwards, the concave allowance in the area of the sand ring is enlarged, and pressure impact is eliminated. Through setting up sleeve pipe 3, can let the sand circle when polishing, have harder region, also have softer region, and lead to sand circle non-deformable to the support of sand circle, can use longer time.
In this embodiment, the end surface of the sleeve 3 is in fillet transition with the outer curved surface; the end surface of the limiting ring 4 is in round angle transition with the outer curved surface.
And the fillet transition is used, so that the inner ring of the sand ring is prevented from being cut by the sleeve 3 and the limiting ring 4. In addition, when pressure is applied to the end of the sleeve 3, an axial component force is obtained to move the sleeve 3.
In the embodiment, the center of the end surface of the head part 1-1 is provided with a plugging needle 5 with a needle point facing to the left side; an exhaust hole is formed in the middle of the left end face of the end cap 2, and the needle point of the plugging needle 5 is inserted into the exhaust hole to form plugging.
It should be noted that, when the end cap 2 is heated and the head 1-1 of the shaft center body 1 is inserted into the end cap 2, the gas in the end cap 2 can be exhausted from the exhaust hole until the needle point of the blocking needle 5 is inserted into the exhaust hole to form a block, and at this time, the shaft center body 1 and the end cap 2 are just installed in place, and then, when the end cap 2 is cooled, the volume of the residual gas in the end cap 2 is reduced to form a negative pressure, so that the installation of the end cap 2 and the shaft center body 1 is very firm and is difficult to assemble and disassemble.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
