Detailed Description
As shown in fig. 1-3, an easy-to-detach axle center device of a replaceable sand ring for nail art comprises an axle center body 1 and an end cap 2 sleeved at one end of the axle center body 1; the end cap 2 is sleeved with a sand ring (not shown in the figure), and 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 1-1, the inner cavity of the end cap 2 is in interference fit with the head 1-1, the outer diameter D1 of the right end of the end cap 2 is larger than the outer diameter D2 of the left end, and D1-D2=0.3 mm-0.7 mm, preferably, D1-D2=0.5 mm.
In this embodiment, the length of the portion with the outer diameter D1 at the right end of the end cap 2 is 1/5-1/4 of the entire length of the end cap 2.
In this embodiment, the transition between the portion of the end cap 2 with the outer diameter D1 and the portion with the outer diameter D2 is made by a ramp 2-1, the ramp angle of the ramp 2-1 being 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 openings 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 where the notch on the end cap 2 is located is larger than the outer diameter of the head 1-1. The plurality of openings are uniformly distributed. The setting of opening makes the right-hand member of end cap 2 be a plurality of jack catchs 2-2, and in the in-service use, when the cover establishes the sand collar, jack catchs 2-2 can inwards shrink, and the sand collar of being convenient for is established, and the existence of opening in addition can give the bigger frictional force of sand collar inner circle, can let end cap 2 give the stronger actuating force of sand collar.
In this embodiment, the opening is in a strip shape, and the length of the opening is 1/3-2/3 of the overall length of the end cap 2, preferably, the length of the opening is 1/2 of the overall length of the end cap 2.
In this embodiment, a gap is provided between the right end of the end cap 2 and the shoulder portion 1-2. The existence of the gap can facilitate the disassembly of the end cap 2, and in practice, the end cap 2 needs to be heated firstly when being installed and disassembled, and the installation and the disassembly are realized by utilizing the principle of thermal expansion and cold contraction.
In this embodiment, the outer surface of the portion with the outer diameter D1 at the right end of the end cap 2 is a rough surface 2-3. The rough surface 2-3 can enable the friction force between the inner ring of the sand ring and the right end of the end cap 2 to be larger after the sand ring is arranged at the right end of the end cap 2, so that the sand ring and the end cap 2 can basically rotate 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 with the outer diameter D1 at the right end of the end cap 2; the outer diameter of the sleeve 3 is smaller than the outer diameter D1 of 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 setting of stop collar 4 and sleeve pipe 3 is in order to let the sand ring when polishing the nail, can obtain better polishing effect. Specifically, because in practice both ports of the sand ring are constrictions, i.e. the diameter of the ports is smaller than the inner diameter of the sand ring; after the sand ring is sleeved on the end cap 2, the left end of the sand ring can be clamped on the limiting ring 4, the sand ring is not easy to fall off, in addition, the sleeve 3 is arranged to support part of the sand ring, because if the part of the sand ring close to the left end is completely supported by the end cap 2, the part of the sand ring, which is not effectively supported by the sleeve 3, can be changed variably due to overlarge gaps between the inner wall of the sand ring and the outer wall of the end cap 2, the problem of deformation easily occurs after the sand ring is not sufficiently supported, but if the outer diameter of the end cap 2 close to the left end is increased, the gap between the inner wall of the sand ring and the outer wall of the end cap 2 is reduced, the sand ring cannot be effectively concave after being subjected to the reverse pressure of nails, the rigid impact to nails is larger, a good polishing effect cannot be achieved, and the part of the sand ring, which is not effectively supported by the sleeve 3, can be changed variably, can be effectively concave in the part of the sand ring due to the unfinished condition of the sleeve 3 in the polishing process.
In practice, the sand ring part opposite to the area between the limiting ring 4 and the left end of the sleeve 3 is a main polishing area, when the area is used for polishing, if the reverse pressure of nails is large, the sleeve 3 is forced to move rightwards, the concave allowance of the area of the sand ring is increased, and the pressure impact is eliminated. Through setting up sleeve pipe 3, can let the sand ring when polishing, have harder region, also have softer region, and support to the sand ring leads to the sand ring be difficult for warping, can use longer time.
In this embodiment, a rounded corner is formed between the end surface of the sleeve 3 and the outer curved surface; and a fillet is transited between the end face of the limiting ring 4 and the outer curved surface.
The use of rounded transition avoids the sleeve 3 and the limiting ring 4 from cutting the inner ring of the sand ring. In addition, it is convenient to apply a force to the end of the sleeve 3 to obtain an axial force component to move the sleeve 3.
In the embodiment, the center of the end face of the head part 1-1 is provided with a plugging needle 5 with a needle point facing to the left; the middle part of the left end face of the end cap 2 is provided with an exhaust hole, and the needle tip of the plugging needle 5 is inserted into the exhaust hole to form a plug.
When the end cap 2 is heated and the head 1-1 of the shaft core 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 tip of the plugging needle 5 is inserted into the exhaust hole to form a plug, and the shaft core body 1 and the end cap 2 are just installed in place at the moment, then after the end cap 2 is cooled, the residual gas in the end cap 2 is reduced in volume to form negative pressure, so that the end cap 2 and the shaft core body 1 are very firmly installed and are difficult to disassemble.
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any simple modification, variation and equivalent structural changes made to the above embodiment according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
