Abstract
The utility model discloses a novel sun -shading umbrella, the skeleton comprises slider -crank mechanism and crank and rocker mechanism, including the mobile jib, be equipped with sliding sleeve, main tributary vaulting pole and rib on the mobile jib, main tributary vaulting pole and rib and mobile jib are articulated, being equipped with extension spring between sliding sleeve and the main tributary vaulting pole hinge, being equipped with the guide arm on the sliding sleeve, be equipped with the auxiliary stay pole on the rib, the one end of main tributary vaulting pole is articulated with the mobile jib, articulated guide arm on the outer hinge of the other end, articulated auxiliary stay pole on the interior hinge. The sun shade can be opened automatically under the extension spring effect, has the dead point at sun shade closed position, can realize fine self -locking function.
Description
Technical field
The utility model relates to a kind of parasols, especially relates to a kind ofly automatically to open the parasols with auto-lock function.
Background technology
Parasols is applied very general now, and it is mainly used to keep the sun off, and also has the effect of covering wind and rain, bothering very much when opening, must first parasols be propped up, then be inserted on ground or base, because parasols volume ratio is comparatively large, weight is also heavier, just very difficult during carrying.And the parasols propped up sometimes oneself landing close, self-locking performance is bad, poor stability, easily causes the accident.Therefore design one can automatically open, the parasols that self-locking performance is good.
Summary of the invention
The purpose of this utility model is to provide a kind of sunshading umbrella, only needs first be inserted on base by parasols, then presses the button umbrella and will automatically open, and self-locking performance is very good.What this addresses the problem that present parasols exists opens an inconvenient difficult problem, achieve parasols convenient, fast, open easily; Self-locking property is very good simultaneously, not only safe but also reliable.
To achieve these goals, the technical solution adopted in the utility model is: a kind of sunshading umbrella, comprise mobile jib, mobile jib is provided with sliding sleeve, main support rod and umbrella frame, main support rod and umbrella frame and mobile jib hinged, extension spring is provided with between described sliding sleeve and main support rod hinge, sliding sleeve is provided with guide rod, and umbrella frame is provided with auxiliary support bar, and one end and the mobile jib of main support rod are hinged, hinged guide rod on the outer hinge of the other end, hinged auxiliary support bar on inner hinge.What the utility model adopted is second order mechanism, be made up of slider-crank mechanism and crank and rocker mechanism, driving link is sliding sleeve, can slide up and down under sliding over the effect of extension spring along mobile jib, drive guide rod to control the folding of support bar, and then realize opening and closing of parasols.Meanwhile, mobile jib is provided with slotted eye, and sliding sleeve is provided with the grab button under torque spring effect, can be stuck in slotted eye, realizing self-locking when arriving upper and lower two extreme positions; When the extreme position opened, there is under the elastic potential energy effect of spring the effect of self-locking, when closed extreme position, there is dead-centre position in slider-crank mechanism, can self-locking be realized, avoid umbrella oneself to open.Which achieves the double self locking when open and close position.
The utility model beneficial effect is: a kind of sunshading umbrella comprises mobile jib, the sliding sleeve be enclosed within mobile jib can slide up and down at mobile jib under the action of the spring, carry out push-and-pull support bar by guide rod again, and then change the angle between two support bars, realize opening with closed of parasols.When angle between support bar is respectively 0 degree and 180 degree, umbrella reaches capacity position, namely closed and state when opening.Because this parasols has automatic opening function, only need first to be inserted on base by umbrella, then press the button and can automatically open, this just saves manpower greatly, avoids the trouble opened rear manpower and go to move.Because the grab button on sliding sleeve can self-locking, the dead-centre position of spring and slider-crank mechanism also has the effect of self-locking, thus realizes double self locking, more safe and reliable.
Accompanying drawing illustrates:
Fig. 1 is the overall structure figure of the utility model parasols.
Fig. 2 is the structure chart of the utility model parasols in open position.
Fig. 3 is the local structural graph of the utility model supporting rod for umbrella.
Detailed description of the invention:
Be further described the utility model below in conjunction with accompanying drawing, a kind of sunshading umbrella of the present utility model, comprises extension spring 1, guide rod 2, sliding sleeve 3, mobile jib 4, umbrella frame 5, main support rod 6, auxiliary support bar 7.
Freedom calculation: have movable part: guide rod 2, sliding sleeve 3, umbrella frame 5, main support rod 6, auxiliary support bar 7;
N=5, p
l=7, free degree h=3 × 5-2 × 7=1
As shown in Figure 1, mobile jib 4, sliding sleeve 3, guide rod 2, CE≤CF in main support rod 6 four-bar mechanism, so form slider-crank mechanism; Mobile jib 4, umbrella frame 5, main support rod 6, BD=DE, AB=AE in auxiliary support bar 7 four-bar mechanism, owing to meeting bar elongate member, so form crank and rocker mechanism.More labour-saving effect can be reached by second order mechanism.Wherein BD=DE in crank and rocker mechanism, AB=AE, so when crank forwards to overlapping with mobile jib, AB and BD also can be overlapping with mobile jib, angle now between two support bars is 0 degree, parasols is in completely closed state, at this moment spring is stretched to extreme position, elastic potential energy is maximum, but the drive line angle due to mechanism is 0 degree, mechanism is in dead-centre position, that is sliding sleeve is immotile along mobile jib direction, even if flexible potential energy also can not action, This prevents umbrella automatically to open, to be on the safe side, sliding sleeve is provided with the grab button under torque spring effect, when reaching the limit of in the slotted eye that position can be stuck on mobile jib, realize locked.
When pressing grab button, as long as stir umbrella frame gently, umbrella will be opened under the action of the spring, but umbrella can only be opened to the position that support bar becomes 180 degree, because be provided with hinge block mechanism between support bar, as shown in Figure 3, two support bars are connected by hinge D, and guide rod is connected by hinge C with main support rod, and the angle between support bar is by 0 degree of increase, when reaching 180 degree, hinge C and auxiliary support bar 7 bump against, and reach the limit of position, namely the state opened of parasols, at this moment the grab on sliding sleeve is stuck in the upper slotted eye of mobile jib, realizes locked.
