Embodiment 1:
Please refer to Fig. 1 and Fig. 2, a kind of structure preventing screw rod positioning of the present utility model, comprises screw rod 10, pedestal 20, locking gear and tumbler 40.
This tumbler 40 can circumferentially be connected to below this pedestal 20 rotationally.Described tumbler 40 is provided with flexible clamping portion, and flexible clamping portion described in the present embodiment is a pair elasticity snap arm 42, and the inner side of described elasticity snap arm 42 is provided with grab 422.Described pedestal 20 is provided with mounting part 22, described mounting part 22 flange in the form of a ring.The grab 422 of described elasticity snap arm 42 and this mounting part 22 circumference can snap together to realize this tumbler 40 and are rotatably assorted with pedestal 20 circumference rotationally.To being provided with screwed hole 44 by screw rod 10 on this tumbler 40.This pedestal 20 is provided with resigning hole 24, and the top of this screw rod 10 is passed this screwed hole 44 and extend in the middle of this resigning hole 24.
In the present embodiment, described tumbler 40 can circumferentially be connected to outside the resigning hole 24 of this pedestal 20 rotationally.
In the present embodiment, described locking gear is a locknut 30, and this locknut 30 to be threaded on this screw rod 10 and to be pressed against the lower end of this tumbler 40.Tumbler 40, locknut 30, screw rod 10 three form the entirety can rotated along pedestal 20 circumferential clocking of turbine.Screw rod 10 will drive tumbler 40 and locknut 30 synchronous axial system when rotating with pedestal 20 circumference is upper, make can not relatively rotate between tumbler 40 and locknut 30, and then make also can not relatively rotate between tumbler 40 and screw rod 10, avoid screw rod 10 positioning.When needing the extension elongation adjusting screw rod 10, only need unclamp this locknut 30, then rotate this screw rod 10, this screw rod 10 can relatively rotate thus realize the axial stretching of screw rod 10 relative to pedestal 20 by this tumbler 40.
Embodiment 2:
Please refer to Fig. 3 and Fig. 4, the difference of the present embodiment and embodiment 1 is:
In the present embodiment, this tumbler 40 can circumferentially be installed within the resigning hole 24 of this pedestal 20 rotationally, described flexible clamping portion is elasticity stuck point 423, described mounting part 22 is the groove of resigning hole inwall, described elasticity stuck point 423 and this groove can circumference rotationally snap-fit engagement be rotatably assorted with pedestal 20 circumference to realize this tumbler 40.
Embodiment 3:
Please refer to Fig. 5 and Fig. 6, the difference of the present embodiment and embodiment 1 is:
In the present embodiment, described locking gear is along the axially extended draw-in groove 11 of screw rod 10 and the Elastic buckle 46 be fixed on connector, realize stoping tumbler 40 to rotate relative to described screw rod 10 by Elastic buckle 46 and the snap-fit engagement of draw-in groove 11, also tumbler 40 synchronous axial system will be driven when namely screw rod 10 rotates with pedestal 20 circumference is upper, can not relatively rotate between tumbler 40 and screw rod 10, avoid screw rod 10 positioning.When needing the extension elongation adjusting screw rod 10, only need to exert oneself rotating screw bolt 10, Elastic buckle 46 stress deformation on tumbler 40 and exit draw-in groove 11, makes this screw rod 10 relatively to rotate thus to realize the axial stretching of screw rod 10 relative to pedestal 20 by this tumbler 40.
Embodiment 4:
Please refer to Fig. 7 and Fig. 8, the difference of the present embodiment and embodiment 1 is:
In the present embodiment, described locking gear is a fastener 30a being socketed in outside screw rod 10, fastener 30a is provided with projection 31, projection 31 be slidably matched along the axially extended draw-in groove 11a of screw rod 10, make that fastener 30a and screw rod 10 are spacing in the circumferential to be coordinated and be axially slidably matched, fastener 30a and the detachable snap-fit engagement of tumbler 40.
In the present embodiment, fastener 30a is provided with hole clipping 32, and on tumbler 40, correspondence is provided with fixture block 48, realizes removably connecting of fastener 30a and tumbler 40 by hole clipping 32 and the snap-fit engagement of fixture block 48.Or also can be that fastener 30a is provided with fixture block as required, on tumbler 40, correspondence be provided with hole clipping.
Tumbler 40, fastener 30a, screw rod 10 three form the entirety can rotated along pedestal 20 circumferential clocking of turbine.Screw rod 10 will drive tumbler 40 and fastener 30a synchronous axial system when rotating with pedestal 20 circumference is upper, and fastener 30a makes can not relatively rotate between tumbler 40 and screw rod 10, avoids screw rod 10 positioning.When needing the extension elongation adjusting screw rod 10, only the hole clipping 32 on fastener 30a need be separated with the fixture block 48 on tumbler 40, fastener 30a is made to remove limit rotation to tumbler 40 and screw rod 10, so i.e. this screw rod 10 rotatable, this screw rod 10 can relatively rotate thus realize the axial stretching of screw rod 10 relative to pedestal 20 by this tumbler 40.
Please refer to Fig. 9, a kind of pushbutton unit of the present utility model, comprise the structure preventing screw rod positioning described in body 50 and two, body 50 is provided with the accommodating cavity of upper and lower opening, pedestal 20 activity is installed in this this accommodating cavity, and pressing pedestal 20 can drive screw rod 10 opposing body 50 to move.Preferably, described screw rod 10 stretches out outside body 50, and the top of this pedestal 20 is connected with cap 60, is also provided with a return springs (not shown) and presses laggard horizontal reset to remove pedestal 20 between this pedestal 20 and body 50.This pushbutton unit of the present utility model can be used on water tank drain valve to open or close the starting switch of draining valve, two prevent the structure of screw rod positioning to be respectively used to control partly discharging water and entirely discharging water of water tank, and due to screw rod can not positioning, push button function is reliable and stable, therefore makes the draining good stability of draining valve.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
