Specific embodiment
Below in conjunction with attached drawing, a preferred embodiment of the present invention will be described in detail.
The present invention is specifically described with reference to the accompanying drawing, as shown in Figs. 1-5, in the present embodiment:
When needing using stool, device is taken out first, main leg casing 22 is first rotated into a smaller angle, then pass through
It can be manually rotated secondary leg casing 29 and main leg casing 22, so that main leg casing 22 and secondary leg casing 29 is formed a stool leg, pass through at this time
Main leg casing 22 is rotated, main leg casing 22 is rotated into vertical angle, and works as main leg casing 22 during rotation, concave plate
On 1 lower surface of stool surface positive stop lug boss 38 beginning contacted with the boss groove 24 on main leg casing 22, positive stop lug boss 38 by with
The curved surfaces of main 25 upper end of leg telescopic mast contact, and by main leg telescopic mast 25, compression, main leg telescopic mast 25 are inserted downwardly into downwards
In secondary leg casing 29, while secondary leg telescopic mast 33 being pressed downward, is inserted into secondary leg telescopic mast 33 in next secondary leg casing 29,
To which the stool leg for forming main leg casing 22 and secondary leg casing 29 is fixed；
Stool leg is assembled at this time finishes, then by rotating rotating handles 6 manually, rotating handles 6 pass through 5 band of controllable register
The dynamic stud 7 that adjusts starts turning, and adjusting the rotation of stud 7 slides the adjusting beginning of support 9 inside groove 8, to drive
Limiting bracket 11 is moved, and the postive stop baffle 15 on limiting bracket 11 passes through the effect of center of gravity block 18, is made on postive stop baffle 15
The main leg groove 16 of arc always vertically, after postive stop baffle 15 moves a certain distance, at this time on postive stop baffle 15
The main leg groove 16 of arc contacted with main leg casing 22, thus by the interaction of postive stop baffle 15 and positive stop lug boss 38, general
Main leg casing 22 is fixed, and keeps main leg casing 22 vertically and fixed；
The assembling of other stool legs is finished using the above method, stool can be used, when needing folding stool；
It first passes through and reversely rotates rotating handles 6, make adjusting support 9 start to be recovered in groove 8, to drive postive stop baffle
15 are detached from main leg casing 22, at this time by the way that main leg casing 22 rotates by a certain angle, make the boss groove on main leg casing 22
24 are detached from positive stop lug boss 38, so that main leg telescopic mast 25 be made to set back by compressed spring 27, secondary leg telescopic mast 33 passes through
Secondary leg compressed spring 35 sets back, to make main leg telescopic mast 25 be detached from secondary leg casing 29, while between secondary leg casing 29
Also it is detached from, secondary leg casing 29 and main leg casing 22 is folded up and can pack up stool at this time.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
