The outer peripheral wall of the first connector 300 is provided with an external thread 320a and a second annular fastening position 320b matched with the first annular fastening position 440 b.
In use, the first connector 300 is inserted into the rotary locking sleeve 440, and rotating the rotary locking sleeve 440 drives the first connector 300 to move into the rotary locking sleeve 440, so that the second annular fastening portion 320b and the second annular fastening portion 320b are fastened together, thereby connecting the heat-generating component 100 and the handle component 200.
When it is desired to detach the heat-generating component 100 from the handle member 200, the second annular locking portion 320b is disengaged from the first annular locking portion 440b by rotating the rotating locking sleeve 440 in the opposite direction, and the first connector 300 is gradually ejected from the rotating locking sleeve 440 by the internal threads 440b of the rotating locking sleeve 440.
Compared with the existing automatic curling iron adopting single thread or buckling position connection and matching, the automatic curling iron provided by the utility model can ensure that the first plug connector 300 and the second plug connector 400 are spliced together to complete the connection of the heating component 100 and the handle component 200 only by rotating the rotary locking sleeve 440, and the disassembly and the insertion are very convenient; when the heat generating component 100 and the handle component 200 are connected in place, the first connector 300 and the second connector 400 are locked by the clamping of the first annular fastening portion 440b and the second annular fastening portion 320b, so that the connection strength of the heat generating component 100 and the handle component 200 is effectively ensured, and the problem of easy loosening caused by thread abrasion is avoided.
In the present embodiment, the first connector 300 includes a housing 310, a first inner plastic body 320, and a plurality of first conductive pins 330. The housing 310 is inserted into the lower end of the heat generating component 100. The upper end of the first inner plastic body 320 is inserted into the housing 310, the lower end of the first inner plastic body protrudes out of the housing 310, and the external thread 320a and the second annular fastening position 320b are disposed on the outer peripheral wall of the first inner plastic body 320. A plurality of insertion holes 320c are formed in the first inner plastic body 320, the first conductive pins 330 are inserted into the corresponding insertion holes 320c, and the upper ends of the first conductive pins 330 penetrate through the first inner plastic body 320 and are electrically connected to the heat generating body disposed in the heat generating component 100. The lower end of the first conductive pin 330 is exposed outward from the lower end opening of the insertion hole 320 c.
The second connector 400 includes a connecting socket 410, a second inner plastic body 420 and a plurality of second conductive pins 430. The lower end of the connection holder 410 is inserted into the handle part 200, and the second inner plastic body 420 is inserted into the connection holder 410. The second conductive pins 430 correspond to the first conductive pins 330 one by one, and have bodies inserted into the second inner plastic body 420, and lower ends extending into the handle member 200 after passing through the second inner plastic body 420 and the connection seat 410, and electrically connected to a circuit board in the handle member 200. The upper end of the second conductive pin 430 extends upward, and when the first connector 300 is connected to the second connector 400, the second conductive pin 430 is inserted into the insertion hole 320c opposite to the second conductive pin 430, and is connected to the heat generating component 100 through the handle member 200 by being inserted into the first conductive pin 330 in the insertion hole 320 c.
The rotary locking sleeve 440 is movably sleeved on the periphery of the connecting seat 410 and the second inner plastic body 420, and when the first connector 300 is inserted into the second connector 400, the rotary locking sleeve 440 is rotated to realize the insertion locking of the first connector 300 and the second connector 400.
Optionally, in the embodiment of the present invention, the lower end portion of the first inner plastic body 320 has a first shaft body (not shown) and a second shaft body (not shown), and the first shaft body is integrally connected with the upper end portion thereof through the second shaft body. The diameter of the first shaft body is smaller than that of the second shaft body, the external thread 320a is arranged on the outer wall of the first shaft body, and the second annular buckling position 320b is arranged on the outer wall of the second shaft body. Correspondingly, the internal threads 440a of the rotating locking sleeve 440 have a diameter greater than the diameter of the first annular snap 440 b.
Therefore, when the first connector 300 can be smoothly inserted into the second connector 400, the external thread 320a is prevented from contacting the first annular fastening position 440 b.
Optionally, in the embodiment of the present invention, the lower end of the rotary locking sleeve 440 has a sealing portion 440c, an avoiding hole (not shown) is formed in the sealing portion 440c, and the lower end of the connecting seat 410 passes through the sealing portion 440c from the avoiding hole and presses the sealing portion 440c onto the upper outer wall of the handle member 200.
Thus, the rotary locking sleeve 440 can be locked to the handle member 200 along with the connecting socket 410, such that when the rotary locking sleeve 440 is rotated, the rotary locking sleeve 440 does not move axially relative to the handle member 200, such that the first plug will move relative to the rotary locking sleeve 440. When locked, the sealing portion 440c is pressed against the outer wall of the upper end of the handle member 200, and the heat generating member 100 is locked to the handle member 200 in the radial direction by friction between the sealing portion 440c and the outer wall of the upper end of the handle member 200.
In order to facilitate the rotation of the rotary locking sleeve 440, a certain gap is formed between the sealing part 440c and the exterior of the upper end of the coupling holder 410 and the handle member 200. When the rotating locking sleeve 440 is rotated, the first inner plastic body 320 of the first connector 300 moves toward the rotating locking sleeve 440 and presses the connecting seat 410 upward, so that the connecting seat 410 moves toward the sealing portion 440c of the rotating locking sleeve 440, and the first connector 300 and the second connector 400 are locked more tightly.
Preferably, a slip-preventing gasket 450 is provided on the upper end surface of the sealing portion 440c, and the slip-preventing gasket 450 is interposed between the sealing portion 440c and the connection holder 410. Thereby to improve rotational damping between the rotary locking sleeve 440 and the connection socket 410 in the locked state. So that the rotary locking sleeve 440 is not easily rotated in the locked state.
Specifically, in the embodiment of the present invention, the anti-slip pad 450 is a rubber pad.
Optionally, in the embodiment of the present invention, the first annular fastening portion 440b is an annular raised annular groove, and the second annular fastening portion 320b is an annular groove. In other embodiments, the first annular snap 440b may be configured as an annular groove and the second annular snap 320b may be configured as an annular protrusion.
The above is only the preferred embodiment of the present invention, not used in the present invention, and any slight modifications, equivalent replacements and improvements made by the technical entity of the present invention to the above embodiments should be included in the protection scope of the technical solution of the present invention.
