Fig. 2 reflects the structural representation of the utility model when returning back to plumbness.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Fig. 4 reflection is installed in the schematic diagram that bends towards the inner spring in the joint.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this knob driving bend towards mechanism mainly by bend towards joint 16, bend towards down joint 1, bend towards connecting rod 2, inner spring 19, back-moving spring 5, conduit 6 and by knob 14, sliding fill in 8 and the knob thrust unit that constitutes of taper pin 9 constitute.
Wherein, bend towards joint 16 and scabble the interlocking portion that forms flat in the cylindric both sides of an end respectively, central authorities of interlocking portion offer a through hole, and open a groove in a side, and an inner spring 19 places in this groove.The other end that bends towards joint 16 is the pipe body, connects on the umbrella handle to save 15.In interlocking portion, have with the pipe body connects and bend towards the connecting rod through hole.
It is cylindric bending towards down joint 1, and its top has one and is suitable for bending towards the short slot that joint interlocking portion embeds, and the short slot both sides form the interlocking rib of symmetry, rabbet rib relatively and have corresponding through hole, are offering an arc track groove on the joint inwall under the bending towards of short slot bottom.The interlocking portion that bends towards joint is embedded in the short slot that bends towards down joint, and both is articulated according to through hole with a pin, and this pin is by placing the inner spring 19 in the groove.
Bend towards connecting rod 2 and be processed into knife-edge, be convenient to strengthen connecting rod strength, be processed with the dowel hole and the slip pin-and-hole of connection usefulness at the upper and lower of connecting rod respectively.The connecting rod lower end passes that joint is saved and bent towards down to bending towards of mutual pivot joint and the end is positioned at the down bottom of joint, and in its end two pulleys 17 that connect with sliding pin is housed.
Knob 14 is a hollow cylindrical, and its inner face has female type teeth groove 7, and this teeth groove 7 is suitable with taper pin head 13.There is the projecting ring section 10 of outside expansion the knob bottom, and knob 14 is enclosed within on the umbrella handle 15, and its bottom projecting ring section 10 stretches in the clip slot in the shell 12 of rocking-handle assembly 11, makes knob 14 be subjected to spacing and can the plane rotation and can upwards not break away from.An axial slide 18 that can supply taper pin to slide up and down is all arranged in the umbrella handle 15 symmetrical both sides of knob 14 installation places.Sliding plug 8 bottoms that are enclosed within conduit 6 are fixed with pin and conduit.The afterbody of taper pin 9 passes an areole of chute 18 on the umbrella handle and sliding plug respectively and is fixed on the sliding plug 8, and two taper pins 9 to be opposition side fixing up and down, the head 13 of taper pin all inserts in separately the teeth groove 7.
Its operation principle is as follows: when parasols launches, umbrella is in perpendicular to the state of ground, make knob 14 rotations with external force, this moment, taper pin 9 was done motion up or down at the female type teeth groove 7 effect lower edge umbrella handle chutes 18 of knob, thereby drive the reciprocating motion that sliding plug 8 associated parts such as grade are done rise and fall, cause to bend towards connecting rod 2 and move, thereby realize bending towards structure motion and drive the inclination on umbrella top or vertical along bending towards down the rail groove of joint in 1.
Clockwise during turn knob 14, taper pin 9 drives sliding plug 8 and moves down, correspondingly make interconnective with it conduit 6, conduit clamping ring 3, bend towards connecting rod 2 stressed declines, this moment back-moving spring 5 pressurizeds, bend towards connecting rod 2 and move down to force along the rail groove that bends towards down joint 1 and bend towards down the joint inclination, in the tilting procedure formula, bend towards inner spring 19 stress deformations, make tilting procedure stablize, rather than tilt suddenly, the allowable angle of inclination that bends towards down joint 1 is set at 30 °.Otherwise, counterclockwise during turn knob 14, taper pin 9 drives on the sliding plug 8 and moves, sliding plug 8 drives conduit 6, conduit clamping ring 3, bends towards connecting rod 2 risings, and spring 5 tensions bent towards connecting rod 2 and rose along bending towards down joint 1 rail groove this moment, bend towards inner spring 19 stressed resiliences, force to bend towards down joint 1 answer, until plumbness, as shown in Figure 2.
