The parasol of umbrella cover tilt adjustable
Technical field:
The utility model relates to parachute kit, particularly the parasol of umbrella cover tilt adjustable.
Background technology
When the sunlight oblique fire, the face that covers of parasol also is offset thereupon and dwindles, and people have to follow covers the face sliding seats.The parasol that the tiltable certain angle of a kind of umbrella cover is arranged on the existing market, its structure is lock core, lock-bit and spring combination, during use, press...with one's finger and press lock core compression spring, after causing lock core and lock-bit separating, firmly move umbrella cover with the another hand again and make its inclination, after adjusting suitable angle, unclamp the finger of pushing lock core, under the effect of recoil of spring power, make lock core enter new lock-bit, thereby make the umbrella cover normal aim at the sun, reach the purpose of covering oblique fire sunlight, this structure button is too high, and operation is also relatively required great effort.
Summary of the invention
The purpose of this utility model provides a kind of parasol of operating light umbrella cover tilt adjustable.
Technical solution of the present utility model is: a kind of parasol of umbrella cover tilt adjustable, the end that comprises upper umbrella rod, upper umbrella disc, following umbrella disk, stay cord is tied to down the rope-swinging device of umbrella disk, it is characterized in that suit pressure pipe in the upper umbrella rod, pulley is equipped with on pressure pipe top, the lower end axle connects slide bar, and the slide bar lower end can move up and down along recessed inclined-plane of knuckle; Between pressure pipe and the upper umbrella rod spring is set, the spring upper and lower side is respectively located in the projection of pressure pipe and knuckle; The upper umbrella rod position of umbrella disk top one segment distance is overlapped spacing collar admittedly under being positioned at.
Be tied to down umbrella disk behind the assembly pulley of being made up of a plurality of pulleys from the stay cord pile warp of rope-swinging device, its middle pulley A is loaded on pressure pipe top, and pulley B is loaded on the spacing collar place.
The projection of above-mentioned knuckle and recessed are connected by the bearing pin axle.
Roller is equipped with in above-mentioned slide bar bottom, makes it can be along recessed inclined-plane scroll-up/down of knuckle.
Adopt the utility model structure, shake rope-swinging device coiling umbrella rope, umbrella disk opens umbrella cover under promoting, and becomes common parasol; If the sunlight oblique fire can continue to shake rope-swinging device, is limited circle stop after following umbrella disk rises a little, the pulling force of umbrella rope continues to act on the pulley on pressure pipe top, drive pressure pipe compression spring, and the drive slide bar moves downward.Because roller is equipped with in the slide bar bottom, its inclined-plane of recessed along knuckle is rolled downwards, and slide bar produces a clockwise torque, forces umbrella cover to rotate, the angle of rotating can be according to locating arbitrarily in the position range of roller in recessed inclined-plane of knuckle, be aided with the Rotatable umbrella bar again, can make the umbrella cover normal point to the sun, reached the purpose of sunshade, the umbrella rope is by the laborsaving function of assembly pulley, drive slide bar downslide umbrella cover and can become gradient, simple to operate, laborsaving convenience.

The specific embodiment:
With reference to Fig. 1, Fig. 2, embodiment comprises umbrella bar, upper umbrella disc 23, the following umbrella disk of being made up of upper umbrella rod 3, middle umbrella bar 13, lower umbrella rod 16 8, and the top of stay cord 12 is tied to the terminal rope-swinging device 15 that is tied to down umbrella disk 8 behind reel for rope 14, the pile warp assembly pulley, assembly pulley is made up of pulley 1,2,6, its middle pulley 1,2 is loaded on pressure pipe 4 tops up and down, and pulley 6 is loaded on spacing collar 5.Pressure pipe 4 is sleeved in the upper umbrella rod 3, and its lower end connects slide bar 10 by pivot pin, and slide bar 10 lower ends can be along recessed inclined-plane scroll-up/down of knuckle.Be connected in series by projection 9 and recessed 11 knuckle that constitutes between upper umbrella rod 3 and the middle umbrella bar 13; Upper umbrella rod 3 positions of a bit of distance in umbrella disk 8 tops are overlapped a spacing collar 5 admittedly under being positioned at.
With reference to Fig. 3, steering component structure shown in Figure 4, between pressure pipe 4 and the upper umbrella rod 3 spring 7 is set, and spring 7 upper ends is pushed up mutually with pressure pipe 4 by back-up ring 20, pin 22, pin-and-hole 4.1; Pressure pipe 4 lower ends are hinged with the upper end axis hole 10.1 of slide bar 10 by axis hole 4.2, pivot pin 21, roller 19 is equipped with in slide bar 10 bottoms, it is hinged with the lower end axis hole 10.2 of slide bar 10 that pivot pin 18 runs through roller 19, the length of pivot pin 18 is greater than the length of axis hole 10.2, as Fig. 5, shown in Figure 6, can be slided relatively along the skewed slot 9.2 of knuckle projection 9 in pivot pin 18 two ends, so that plunger roller 19 is when the inclined-plane 11.1 of recessed 11 on knuckle rolls downwards, force knuckle projection 9 to rotate (in conjunction with Fig. 7, shown in Figure 8), rotate thereby drive upper umbrella rod 3.The projection 9 of knuckle and the 11.2 concavo-convex cooperations of recessed 11 straight trough, and by pivot pin 17 that both are hinged.Pressure pipe 4 upper ends have rectangular window 4.3 and 4.4 up and down, and upper umbrella rod 3 upper ends have rectangular window 3.1, for the stay cord 12 turnover pile warp pulleys 6 of the pulley 1,2 of pile warp in it.
The course of work: when rotating rope-swinging device 15, umbrella rope 12 is tightened up, and at first umbrella disk 8 opens umbrella cover under the pull-up, and this moment, state was general parasols; Be rotated further rope-swinging device 15, because of umbrella cover opens fully, the pulling force of umbrella rope 12 acts on the pulley 2, by pressure pipe 4 compression springs 7, drive slide bar 10 and move downward, plunger roller 19 rolls torque of projection 9 generations downwards along the inclined-plane 11.1 of recessed 11 on knuckle, force whole umbrella cover generation deflection, play the optimum efficiency that blocks oblique fire sunlight.Because rope-swinging device 15 has ratcher function, thus plunger roller 19 can be in inclined-plane 11.1 scopes arbitrary fixed-site, best sunshade angle is chosen in adjusting.
