In the present embodiment, the inner circumferential of described sliding nut 200 is provided with at least one slide block 210 that can be slidingly fitted with sliding tray 110, being slidably matched sliding nut 200 to slide axially and being socketed in outside sleeve body 100 by slide block 210 and sliding tray 110.In the present embodiment, described slide block 210 number is set to two and is arranged symmetrically with.
In the present embodiment, circumference is rotated sliding nut 200 and is with movable slider 210 to move to holddown groove 140 sliding nut 200 is carried out axial limiting, and slide block 210 and holddown groove 140 are the first described position-limit mechanism.
In the present embodiment, described slide block 210 is provided with stop surface 240, described slide block 210 when holddown groove 140 inner circumferential rotates or when locking nut 300 is locked on sliding nut 200 stop surface 240 coordinate with circumferential limited wall 150 is mutually spacing, stop surface 240 and circumferential limited wall 150 are the second described position-limit mechanism.
In the present embodiment, the top ends of described sliding nut 200 is provided with at least one cantilever 220, the top end face of described cantilever 220 be provided with can with the second spacing fixture block 221 of the first spacing fixture block 121 phase snap-fit engagement, circumference rotates sliding nut 200 to make the first spacing fixture block 121 spacing sliding nut 200 to be carried out circumference with the second spacing fixture block 221 phase snap-fit engagement, and the first spacing fixture block 121 and the second spacing fixture block 221 are the 3rd described position-limit mechanism.
In the present embodiment, the top ends of described sliding nut 200 is provided with at least one slot to make way 230, slot to make way 230 extends to the top end face of sliding nut 200, described cantilever 220 stretches into slot to make way 230 and its end face flushes with the top end face of sliding nut 200 and is positioned at directly over slide block 210, and the second spacing fixture block 221 is positioned at the end of cantilever 220 and the end face along cantilever 220 raises up.
In the present embodiment, described slot to make way 230 number is set to two, described cantilever 220 number be set to two and with slot to make way 230 one_to_one corresponding.
Locking nut 300, it is provided with the internal thread that can coordinate with the external screw thread bolt of sliding nut 200, this locking nut 300 be socketed in sliding nut 200 outer and by the threaded of internal and external threads by locking nut 300 interlocking in sleeve body 100.
The mounting method of the quick attach structure of this leading sleeve is:
Step 1, is installed in tap bottom or table top by sleeve body 100; In the present embodiment, screw 10 bolt preset by the external screw thread of sleeve body 100 and tap bottom or table top is coordinated and is connected bottom sleeve body 100 and tap separately.
Step 2, sliding nut 200 is slid axially be socketed in sleeve body 100 outer and move to correct position time circumference rotate that the circumference of sliding nut 200 sliding nut 200 being carried out axial limiting by the first position-limit mechanism, when being locked by sliding nut 200 by the second position-limit mechanism is spacing, by the 3rd position-limit mechanism sliding nut 200 to be carried out circumference locking spacing; In the present embodiment, circumference rotate sliding nut 200 with movable slider 210 move to holddown groove 140 sliding nut 200 carried out axial limiting and stop surface 240 coordinates with circumferential limited wall 150 is mutually spacing to be locked by sliding nut 200 time spacing, the first spacing fixture block 121 of circumference and the second spacing fixture block 221 phase snap-fit engagement locking spacing sliding nut 200 to be carried out circumference.
Step 3, is enclosed within locking nut 300 outside sliding nut 200, and coordinates locking nut 300 interlocking in sleeve body 100 with sliding nut 200 bolt, completes the installation of leading sleeve.In the present embodiment, realized the interlocking of locking nut 300 and sliding nut 200 by the internal thread of locking nut 300 and the externally threaded threaded of sliding nut 200.
Because rib 120 and holddown groove 140 are arranged along sleeve body 100 length direction interval, when table top thinner or thicker time, after slide block 210 can being slid into correct position, slide block 210 slips in holddown groove 140 with the correct position making sliding nut 200 be positioned at sleeve body 100 by circumference rotation sliding nut 200 again, facilitate the interlocking of locking nut 300, locking nut 300 only need with the external screw thread bolt of sliding nut 200, the number of turns that locking nut 300 rotates is less, easy to adjust, fast, and avoid due to table top thinner time locking nut 300 need to rotate through many number of turns and the inconvenience that causes.And during dismounting, due to the elastic reaction of cantilever 220, when reversely rotating locking nut 300, the second spacing fixture block 221 can be left the first spacing fixture block 121 by its revolving force, more axially pulls locking nut 300 sliding nut 200 can be skidded off sleeve body 100 simultaneously, realizes quick detach.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process according to this, the equivalence change namely done according to the scope of the claims of the present invention and description with modify, all should still belong in scope that the present invention contains.
