The utility model is achieved in that a kind of up-down locking limit structure, and its special way is: comprise pipe, on manage stop collar, time pipe, briquetting, spanner plate and stop collar;
On the wallboard of said stop collar through slot is arranged, a upper pedestal and a lower base are arranged respectively in through slot upper end and bottom;
Said stop collar is arranged on down the top of pipe and removably connects; The eccentric cam of spanner plate and upper and lower pedestal articulate, and briquetting is arranged in the through slot, and the briquetting one side cooperates with eccentric cam, another side cooperates with last pipe;
Said spanner plate is processed by eccentric cam and bearing pin integrated injection molding;
Last pipe stop collar is arranged on down in the pipe and with following pipe and is slidingly matched, and last pipe passes stop collar and stretches out pipe down.
Described a kind of up-down locking limit structure, its special way is: draw-in groove is arranged at said pipe top down;
The outer shroud edge is arranged at the top of said stop collar, and process with upper pedestal is one-body molded on the outer shroud edge, and in stop collar embedded and manages down, the outer shroud edge cooperated stop bit with the upper end and the lower base of managing down with the lower end of draw-in groove, and lower base stretches out from draw-in groove.
Described a kind of up-down locking limit structure, its special way is: button bit and half pin shaft hole are arranged on the said upper and lower pedestal, and button bit is communicated with half pin shaft hole, and the bearing pin of eccentric cam top and bottom and half pin shaft hole are rotatably assorted;
Flexible button on the said briquetting, the elasticity button on the briquetting and the button bit of upper and lower pedestal fasten.
Described a kind of up-down locking limit structure, its special way is: also comprise a friction plate, friction plate is arranged on the briquetting, and friction plate cooperates with last pipe.
Described a kind of up-down locking limit structure, its special way is: said friction plate is processed by elastic material.
Described a kind of up-down locking limit structure, its special way is: on the said friction plate face relative with last pipe anti-skidding line is arranged.
A kind of up-down locking of the utility model limit structure; Owing to adopt such structure, during assembling, at first spanner plate embedded in the through slot of stop collar; The eccentric cam of spanner plate and upper pedestal and upper pedestal articulate; Briquetting and upper and lower pedestal removably connect, and stop collar embeds interior the getting final product of draw-in groove of pipe down, so easy to assembly; During dismounting, the eccentric cam of spanner plate is separated with briquetting, can stop collar separate with pipe down, then briquetting is separated with stop collar, spanner plate separates with the upper and lower pedestal of stop collar, so convenient disassembly.
