The specific embodiment
As accompanying drawing 1, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, shown in the accompanying drawing 7, a kind of dining chair, comprise front pole-bracket 3, the back pole-bracket 1 that the upper end is connected with the upper end of described front pole-bracket 3, be arranged on the seat mechanism 2 on the front pole-bracket 3, it is characterized in that: seat mechanism 2 can be slidingly arranged in along the length direction of front pole-bracket 3 on the front pole-bracket 3, have at least two lockholes 11 on the front pole-bracket 3, be provided with tapered end 22 in the seat mechanism 2 slidably, tapered end 22 has locking and two duties of release, when tapered end 22 is under the locking duty, tapered end 22 is inserted in the lockhole 11, when tapered end 22 is under the release duty, tapered end 22 breaks away from lockhole 11, also be connected with rotationally in the seat mechanism 2 and draw barre 12, draw to have first inclined-plane 20 on the barre 12, also be provided with locking piece 13 in the seat mechanism 2 slidably, tapered end 22 is arranged on the locking piece 13 regularly, having 23, the first inclined-planes 20, second inclined-plane on the locking piece 13 cooperates mutually slidably with second inclined-plane 23.
Draw to have draw-in groove 31, the first inclined-planes 20 on the barre 12 and be positioned on the madial wall of draw-in groove 31, locking piece 13 is positioned at draw-in groove 31.
Draw between barre 12 and the seat mechanism 2 and be connected rotatedly by rotating shaft 17.
Draw and be provided with first elastic component 15 between barre 12 and the seat mechanism 2.
The top of tapered end 22 has tapered end inclined-plane 25, when tapered end 22 from the locking duty to the process of release duty conversion, tapered end inclined-plane 25 is against on the front pole-bracket 3.
Have pilot hole 24 on the locking piece 13, pilot hole 24 is built-in with cylinder guide post 16, and locking piece 13 is slidingly connected with seat mechanism 2 mutually by cylinder guide post 16.
Be provided with second elastic component 33 between locking piece 13 and the seat mechanism 2.
First inclined-plane 20, second inclined-plane 23 all are screw inclined plane.
As accompanying drawing 3, accompanying drawing 5, shown in accompanying drawing 8, the accompanying drawing 9, first elastic component 15 is a reset tension spring, and reset tension spring one end links to each other with seat mechanism 2, and an end links to each other with drawing barre by drawing the extension spring junction button 21 on the barre 12, and second elastic component 33 is a reseting pressuring spring.During locking, locking piece 13 is in the lock state under the effect of reseting pressuring spring, and tapered end 22 inserts in the lockhole 11, thereby has fixed the position of seat mechanism 2 on front pole-bracket 3; During release, the effect of drawing barre 12 to overcome reset tension spring clockwise rotates around positioning rotating shaft 17, because being slidingly matched of first inclined-plane 20 and second inclined-plane 23, make and draw barre 12 to convert locking piece 13 to along the slip on cylinder guide post 16 axis directions in rotation around positioning rotating shaft 17, locking piece 13 overcomes the effect of reseting pressuring spring and slides along the direction of axis line of cylinder guide post 16, tapered end 22 is extracted out from lockhole 11, thus release, and release back seat mechanism 2 can slide up and down on front pole-bracket 3.
Shown in accompanying drawing 3, accompanying drawing 5, accompanying drawing 7, accompanying drawing 9, because the top of tapered end 22 has tapered end inclined-plane 25, so also can be under the effect of the enough big power that upwards promotes under lock-out state, the effect that overcomes reseting pressuring spring forms release, promote seat mechanism 2 to another latched position, promptly tapered end 22 can form from release and on new latched position and form self-locking.
As shown in Figure 1, seat 8 is positioned at highest point and is in the lock state.
As shown in Figure 2, seat 8 is positioned at lowest part and is in the lock state.
Because seat mechanism 2 is slidingly arranged on the front pole-bracket 3, locking piece 13 can the position of fixed seating mechanism 2 on front pole-bracket 3, draw barre 12 to be arranged in the seat mechanism 2 rotationally and control the release and the locking of locking piece 13, thus the seat height of dining chair can regulate, and easy and simple to handle.
