Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Examples, see fig. 1-5: the utility model provides a high automatic umbrella of security, includes well stick 4, the umbrella stand (the attached drawing does not draw) of installing on this well stick 4 through last nest (the attached drawing does not draw) and well nest (the attached drawing does not draw), be fixed in the interior seat 5 of 1 bottom of inner tube, automatic umbrella device of opening and receiving and the well stick 2 of preventing to receive the umbrella time well stick 4 and the safety device of the unexpected bounce-back of outer tube 3 etc. of outer tube 3 by inner tube 1, well intraductal 1 is provided with ABS pipe 6. Wherein, automatic umbrella device of opening and receiving includes again: an umbrella opening spring 7, a bullet 8, a control tube 9 arranged in the inner seat 5 for positioning the bullet 8, a hook plate 10 for locking the bullet 8 in the control tube 9, an umbrella opening cord 11, and the like. The safety device includes a shaft body, a spool 12, a ratchet 13, a clockwork spring 14, a safety rope 15, a stopper 16 for restricting reverse rotation of the ratchet 13, and an elastic member 17 for urging the stopper 16 toward the ratchet 13. One end of the safety pull rope 15 is connected with the top of the upper nest at the upper end of the outer tube 3 of the middle rod 4, and the other end is connected with the winding wheel 12. The reel 12 is normally mounted in the cavity of the handle 18 below the control tube 9, and the elastic member 17 pushes the stopper 16 towards the ratchet 13. When the umbrella is opened, the bullet head 8 is locked in the control tube 9, the originally folded middle rod 4 stretches upwards under the action of the umbrella opening spring 7 and simultaneously pulls the safety pull rope 15 out of the winding wheel 12, and the winding wheel 12 rotates reversely and winds up the clockwork spring 14; when the umbrella is folded and the middle rod 4 is folded, the bullet head 8 slides downwards under the pushing action of the ABS conduit 6 and pushes the stop piece 16 to release the ratchet wheel 13, the winding shaft 19 rotates in the positive direction under the action of the clockwork spring 14, and the winding wheel 12 is driven to the recovery winding safety pull rope 15. The above structure is the prior art, and the detailed structure, principle and function thereof are not described herein again.

The utility model discloses an improvement part lies in: the shaft body comprises a winding shaft 19 and a damping shaft 20 which are positioned on the same central axis, and the winding shaft 19 is movably connected with the damping shaft 20; the winding wheel 12 is mounted on a winding shaft 19, the ratchet wheel 13 is mounted on a damping shaft 20, and the clockwork spring 14 acts on the winding shaft 19; a damper 21 is arranged between the winding wheel 12 and the ratchet wheel 13 in a matching way. One end of the winding shaft 19 is provided with a sliding cavity, and one end of the damping shaft 20 is installed in the sliding cavity and can freely rotate in the sliding cavity, so that the winding shaft 19 is movably connected with the damping shaft 20, and the winding shaft 19 and the damping shaft 20 can rotate relatively. Wherein, attenuator 21 is the silica gel damping circle, the side that take-up pulley 12 is relative with ratchet 13 is provided with the annular cell body that matches with the silica gel damping circle respectively, the silica gel damping circle is installed in the annular cell body between take-up pulley 12 and ratchet 13. When the umbrella is opened, the bullet head 8 is locked in the control tube 9, the middle tube 2 and the outer tube 3 of the originally folded middle rod 4 extend upwards under the action of the umbrella opening spring 7 and simultaneously pull out the safety pull rope 15 from the winding wheel 12, the ratchet wheel 13 is fixed by the stop piece 16, the acting force of the umbrella opening spring 7 is greater than the damping force between the ratchet wheel 13 and the winding wheel 12, so that the winding wheel 12 rotates reversely and the clockwork spring 14 is tightened; when the umbrella is folded and the middle tube 2 and the outer tube 3 of the middle rod 4 are folded, the bullet head 8 slides downwards under the pushing action of the ABS conduit 6 and pushes the stop piece 16 to release the ratchet wheel 13, so that the winding shaft 19 rotates forwards under the action of the clockwork spring 14 and the winding wheel 12 moves towards the recovery winding safety pull rope 15. And when the umbrella is not completely folded in the umbrella folding process, namely the ABS conduit 6 does not push the stop piece 16 to loosen the ratchet wheel 13, if the middle pipe 2 and the outer pipe 3 of the middle rod 4 are pulled out by accidental operation, at the moment, although the ratchet wheel 13 is locked, the soft connection is formed between the ratchet wheel 13 and the winding wheel 12 through the damping force of the silica gel damping ring, the safety pull rope 15 is pulled up under the acting force of the upper nest of the outer pipe 3, the acting force is greater than the damping force, the winding wheel 12 rotates to release the safety pull rope 15, the damage of the ratchet wheel 13, the stop piece 16 and other accessories is avoided, the accident caused by accidental ejection of the middle pipe 2 and the outer pipe 3 of the middle rod 4 is prevented, and the safety of the umbrella is greatly.

The middle part of the stop piece 16 is rotatably arranged in the inner seat 5 through a rotating shaft 26, the stop piece 16 is provided with a first arm 22 and a second arm 23, the first arm 22 is provided with a pressing part 24 extending to the inner cavity of the control tube 9, the second arm 23 is provided with a clamping part 25 capable of clamping the tooth surface of the ratchet wheel 13, and the rotating shaft is arranged on one side of the control tube 9; when the bullet 8 is positioned in the inner cavity of the control tube 9, the pressing part 24 of the first arm 22 is pressed downward by the bullet 8, and the second arm 23 and the locking part 25 of the stopper 16 swing outward against the elastic force of the elastic member 17 to disengage from the tooth surface of the ratchet 13; when the bullet 8 retreats, the first arm 22 loses the downward pushing force of the bullet 8, and the second arm 23 is pressed toward the ratchet 13 by the elastic member 17 so that the engaging portion 25 abuts against the tooth surface of the ratchet 13 to prevent the ratchet 13 from reversely rotating. The design structure can reduce the occupation of the inner space of the umbrella handle 18 as much as possible.

In this embodiment, the elastic member 17 is a bent elastic steel piece abutting against the second arm 23, and the elastic member 17 pushes the second arm 23 of the stopper 16 in the inward direction to keep the second arm 23 in a tendency of abutting against the ratchet 13.

In this embodiment, the upper end cover of the control tube 9 is provided with a sliding seat 27 capable of sliding up and down along the control tube 9, the lower side of the sliding seat 27 is connected with a sliding seat spring 28 capable of enabling the sliding seat 27 to slide and reset upwards, the middle tube 2 and the outer tube 3 push the sliding seat 27 to slide downwards when the umbrella is folded, and the sliding seat 27 elastically resets to provide extra pushing force for opening the umbrella for the middle tube 2 and the outer tube 3 when the umbrella is opened.
