The specific embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explain below.
Embodiment one: like Fig. 1, Fig. 2 and shown in Figure 3; A kind of brill fixing umbrella, comprise umbrella cover 15, support bar 17 and drill bit 2, said support bar 17 is provided with steering knuckle 16; The user just can rotate umbrella cover 15 easily like this; Thereby effectively block wind, rain or the sunlight of different directions, said drill bit 2 is an augers, can screw or unscrew face more apace.
This fixture also comprises the worm gearing in a sleeve 3 and the sleeve 3, and said sleeve 3 tops link to each other with support bar 17, and said worm gearing is made up of drive sleeve 4 and inner transmission worm screw, brill ground bar 1 thereof; This transmission worm screw comprises the ratch with helical tooth 61 6 on top and the pole 5 of bottom, and the top of said ratch 6 and sleeve 3 are fixed together, and is arranged with compression spring 8 on the said pole 5; Conflict respectively on drive sleeve 4 bottoms and ratch 6 in the two ends of compression spring 8, said drive sleeve 4 is the cylindric of bottom lock, and the bottom of its sealing is provided with the through hole that supplies pole 5 to pass; Pole 5 outstanding drive sleeve 4 parts are provided with stop part 12; It is a nut that present embodiment is ended block piece 12, and pole 5 ends are provided with the screw thread that matches, so design; Then can regulated at will pole the length of 5 outstanding drive sleeve 4; Thereby reach the purpose of control drive sleeve 4 strokes, and then realize the effect of control drill bit 2 spiral strokes, an end of compression spring 8 can be conflicted on the bottom of drive sleeve 4; Also can be to be fixed on drive sleeve 4 bottoms, and the other end of compression spring 8 be conflicted on ratch 6; Said drive sleeve 4 inwalls are provided with the double wedge 7 that matees and can walk with above-mentioned helical tooth 61 within it; For guaranteeing the stationarity of transmission; Said helical tooth 61 is at least two with double wedge 7, is two in the present embodiment, and is symmetrically set; Said brill ground bar 1 is sheathed in the sleeve 3 and conflict with drive sleeve 4 in its top joins, and said drill bit 2 bar 1 protrudes on the bottom of sleeve 3 with being located at said brill.
For avoiding drive sleeve 4 and ratch 6 tops to produce big impulse force influence; Be arranged with buffer stopper 11 at ratch 6 tops; Be the distance of control drive sleeve 4 with sleeve 3 relative motions; Be provided with the ring-type retaining along 9 at sleeve 3 inwalls, constitute the stroke band that drive sleeve 4 is moved between the buffer stopper 11 at this retaining edge 9 and ratch 6 tops, drive sleeve 4 outer walls are provided with the stopper that card ends and can in above-mentioned stroke band, walk; Said stopper is the convex edge 10 that is provided with around drive sleeve 4 outer walls, and the purpose that the stroke band is set is to avoid taking off tooth between ratch 6 and the double wedge 7.
The course of work of the utility model is following: need umbrella be bored ground fixedly the time, hold sleeve 3 and also exert pressure downwards, because of sleeve 3 is fixedly connected with the ratch 6 of transmission worm screw; Therefore ratch 6 also moves downward thereupon; The helical tooth 61 of ratch 6 is meshing with each other with the double wedge 7 of drive sleeve 4, just drives drive sleeve 4 rotations, and then drives brill ground bar 1 and terminal drill bit 2 rotations thereof; Compression spring 8 accumulation of energys of drive sleeve 4 inside at this moment; Put aside to a certain degree when its energy and just can discharge, impel drive sleeve 4 to be rotated down during release, just can further drive and bore ground bar 1 and terminal drill bit 2 rotations thereof; Just can screw in sandy beach or earth easily so repeatedly, reach the purpose that umbrella is fixing.The utility model is through inner worm gearing transmission, and its principle is safe and reliable, uses easy to operately, and active force and good fixing effect also do not affect the appearance, and the indoor and outdoor that can be widely used in frame boards such as tent, parasol, beach umbrella is fixed.
Embodiment two: like Fig. 6, Fig. 4 and shown in Figure 5; Ratch 6 tops of the worm screw of transmission described in the present embodiment only are connected with sleeve 3 cards; On the ratch 6 of sleeve 3 and transmission worm screw, be respectively equipped with the keeper A13 and the keeper B14 of mutual card fastening position; Keeper A13 and keeper B14 fixedly are processed on sleeve 3 and the ratch 6 through machining modes such as extrusion modling, castings respectively, and keeper A13 and keeper B14 are provided with groove and the fin that mutual card ends, and they can be cross recess (shown in Figure 5); Also can be blade groove (shown in Figure 6), all the other structures be identical with embodiment one in the present embodiment.
Because ratch 6 and sleeve 3 cards are connected with onlying, when applying external force sleeve 3 is moved downward, because the card of ratch 6 and sleeve 3 only acts on; Ratch 6 can move downward with sleeve 3 equally; Thereby realize with embodiment one in identical effect, the benefit of design is like this: card only ways of connecting is convenient to process and dismounting, can corresponding component be processed respectively; Assemble same easy access and transportation afterwards.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
