CN2455104Y - Automati declining top device for sunshade - Google Patents

Abstract

The utility model discloses an automatic head-declining device for a sunshade umbrella, which is arranged between an upper and a lower umbrella columns and is composed of sleeves inside the umbrella columns, an upper and a lower shaking heads mutually hinged, connecting rods for connecting the sleeves and the upper and the lower shaking heads by pins, a pulley off the center line of the sleeves, an umbrella line sheathed on the pulley, springs between the sleeves and the upper shaking head, etc. A hand-rocking shaft is wound on the umbrella line and the umbrella is firstly opened to continue to wind the umbrella line and generate deflection force moment so that the head of the umbrella is rotated around the connecting pins of the upper and the lower shaking heads and a declined groove of the upper and the lower shaking heads guides the direction. The utility model has the advantages of declined angle adjustment through the winding of the umbrella line, labor saving, convenient and automatic head-declined completion, and optimum sunshade effect.

Description

The automatic deflection device of parasols head

The utility model relates to the parasols as the tourism and leisure product, especially the automatic deflection device of the head of parasols.

At present, the parasols that we see on market, a kind of is that ordinary straight is vertical, another kind is the tiltable certain angle of umbrella head, wherein sunshade head inclination institute operative installations is generally manually, its structure is a 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, the head of firmly moving umbrella with the another hand makes its inclination again, adjust suitable angle after, unclamp the finger of pushing lock core, under the effect of recoil of spring power, make lock core enter new lock-bit, regulate the purpose that covers oblique fire sunlight thereby reach, adopting said structure one is the complicated effort of operation, and opening when umbrella and umbrella head deflection are two mutual incoherent mechanisms and deflection needs two hands to be used; The 2nd, the lock-bit groove generally has only 3, and angle excursion is difficult for adjusting and reaches best shaded effects.

The purpose of this utility model provides and a kind ofly can make parasols head arbitrary deflection location in the certain angle scope, umbrella open and deflection can continued operation be finished labour-saving simple to operate device.

Technical solution of the present utility model is: between upper umbrella rod and lower sunshade pole, be provided with upper umbrella rod fixing on shake the head and with fixing following the shaking the head of lower sunshade pole, on shake the head that to have the twice angle of bevel be 30 °-50 ° in the bottom, have the twice vertical groove in the middle of shaking the head down.On the top of shaking the head under inserting, bottom of shaking the head be connected to articulated structure with connecting pin; In upper umbrella rod, be provided with tubular sleeve, sleeve centerline and umbrella post central lines, have in the upper cartridge slotted hole depart from the center vertical line and with on the skewed slot upper end position same side of shaking the head pulley is housed, guide runner is equipped with in the sleeve upper end, link pin articulated linkage upper end is used in the lower end, movable lower link pin is equipped with in the connecting rod lower end, and the mid portion of lower link pin passes the twice skewed slot of shaking the head, and the pin two ends place down in the twice vertical groove of shaking the head simultaneously; Last shake the head and sleeve between spring is housed, the umbrella rope sling is on pulley, an end passes upper umbrella rod and following umbrella disk and fixes, the other end pass sleeve, spring, on shake the head, shake the head down, fix with the axle of shaking the hand in the middle of the umbrella post.

Adopt said structure,, after umbrella disk opens umbrella fully under mentioning, become the ordinary straight umbrella when the coiling umbrella rope of shaking the hand.Continue to shake and shake the hand, the pulling force of umbrella rope acts on the pulley, drive the sleeve compresses spring, the interlock side rod produces and to move downward, and produces a clockwise torque and since the lower link pin under shake the head in the chute, at last, force shake the head skewed slot and the removable pin generation relative motion of connecting rod lower end, the head clockwise direction of umbrella is rotated around the connecting pin of shaking the head up and down, the angle of rotation can be according to location variation arbitrarily in the position range of removable pin in skewed slot.Reached the purpose of umbrella head deflection sunshade.And simple to operate, laborsaving convenience.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Embodiment: as Fig. 1, the utility model by under shake the head 1, lower link pin 2, connecting pin 3, on shake the head 4, connecting rod 5, go up link pin 6, upper umbrella rod 7, lower sunshade pole 16, spring 8, sleeve 9, umbrella rope 10, pulley 11, slide block 12, pulley spindle 13, pin 14, back-up ring 15 and form.The sleeve 9 of tubulose places upper umbrella rod 7 center lines and upper umbrella rod central lines, the upper end is outer to have slide block 12 to make guiding up and down, slide block has the hole for 12 times and departs from upper umbrella rod 7 center lines pulley spindle 13 and pulley 11 are housed in sleeve 9, in sleeve 9 lower ends with connecting rod steady pin 6 with iron shape connecting rod and upper end are hinged partially; On 4 tops of shaking the head insert in the upper umbrella rod 7 fixing, under 1 bottom of shaking the head insert in the lower sunshade pole 16 fixing, as Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, insert in following 1 upper slot of shaking the head of tubulose 4 bottoms of shaking the head on the tubulose, and both are hinged with above-mentioned with connecting pin 3; Connecting rod 5 lower ends with 2 activities of lower link pin with on the 4 lower end skewed slots of shaking the head be connected, angle of bevel is 30 °-50 °, pulley spindle 13 positions and on the 4 skewed slots upper end homonymy of shaking the head, its two ends place down in the 1 twice vertical groove of shaking the head simultaneously; Sleeve 9 and on shake the head spring 8 be installed between 4, connecting rod 5 lower end lower link pins 2 are close to shake the head 4 skewed slots upper end; Umbrella rope 10 is enclosed within on the pulley 11, and an end connects umbrella disk down, and the other end then is connected with the axle of shaking the hand, and umbrella rope 10 is to pass sleeve 9 upper end holes to enter in the sleeve 9, pass again in the spring 8, on shake the head in 4, shake the head in 1 down and in the lower sunshade pole 16, arrive at last and shake the hand spool.

Dynamic effect of the present utility model is such: when the rotation axle of shaking the hand, umbrella rope 10 is tightened up, and at first umbrella disk opens parasols under the pull-up, and this moment, state was general parasols; Be rotated further the axle of shaking the hand, because of umbrella opens fully, the pulling force of umbrella rope 10 acts on the pulley 11, by sleeve 9 compression springs 8, drivening rod 5 moves downward, lower link pin 2 because of not only in last 4 skewed slots of shaking the head but also under shake the head in 1 vertical groove, because of pulley 11 is disalignments, certainly lead to a torque, so just force and shake the head 4 around connecting pin 3 deflections, lower link pin 2 last shake the head 4 skewed slots downwards and along under the downward compound relative motion of 1 vertical slots of shaking the head, thereby make whole umbrella head generation deflection, play the optimum efficiency that blocks oblique fire sunlight.This device also can be in the last 4 skewed slot scopes of shaking the head arbitrary fixed-site, regulate and choose best sunshade angle.
