Abstract
The utility model discloses a rope looseness preventing device which is simple in structure and can prevent the rope from loosing. The structure of the device comprises an umbrella nest body, wherein the umbrella nest body is provided with a rope looseness preventing mechanism, through which umbrella ropes pass. The rope looseness preventing device is simple in structure and can effectively prevent the rope from loosing.
Description
Technical field
The utility model relates to a kind of parasols, relates in particular to the device that is used on a kind of parasols to prevent that rope is loosening.
Background technology
Because the common volume of parasols is bigger, when opening or pack up, need bigger power, in order to open or pack up umbrella easily, a rope is set on umbrella usually, utilize pulley, like a cork umbrella is opened or packed up, at present, umbrella is when open mode, and rope is subjected to bigger power, loosening in order to prevent rope, usually rope is tied up on the umbrella rod, this operation is cumbersome, and insecure.
Summary of the invention
The utility model provides a kind of simple in structure at deficiency of the prior art, can prevent the rope locking device that rope is loosening.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: rope locking device, its structure comprise umbrella nest body, and described umbrella nest body is provided with the rope locking gear, and the umbrella rope passes the rope locking gear.
In the technique scheme: described rope locking gear comprises umbrella nest body, and described umbrella nest body is provided with " V " font groove, and the umbrella rope passes " V " type groove.
In the technique scheme: be provided with sawtooth in described " V " font groove.
In the technique scheme: the A/F of described " V " font groove " V " word is greater than the diameter of umbrella rope, and the bottom width of described " V " font groove " V " word is less than the diameter of umbrella rope.
In the technique scheme: described rope locking gear comprises umbrella nest body, and described umbrella nest body is provided with " U " type groove, is provided with pulley in described " U " type groove, and the side of described U type groove is provided with one and falls " V " type groove, and the umbrella rope passes " V " type groove.
In the technique scheme: described pulley is provided with sawtooth.
In the technique scheme: the opening part of described " V " font groove " V " word and the distance of pulley are greater than the diameter of umbrella rope, and the bottom of described " V " font groove " V " word and the distance of pulley are less than the diameter of umbrella rope.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
1) when umbrella in opened condition the time, stirs rope gently, rope card jail can be prevented that rope is loosening, made things convenient for operation;
2) can securely rope be fixed, can prevent effectively that rope is loosening.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Embodiment one:
Referring to Fig. 1, Fig. 2, Fig. 3, its structure of rope locking device comprises umbrella nest body 1, and described umbrella nest body 1 is provided with " V " font groove 2, is provided with sawtooth 4 in described " V " font groove, and umbrella rope 3 passes " V " type groove, and described sawtooth 4 prevents that umbrella rope 3 from sliding.
Described " V " font channel opening place width is greater than the diameter of umbrella rope 3, described " V " font groove bottom width is less than the diameter of umbrella rope 3, the umbrella rope can be along V-arrangement nest move left and right, and when the umbrella rope was in position A, the umbrella rope can move up and down, when the umbrella rope is pulled to the parachute-opening position, the umbrella rope is moved to position B, because umbrella rope flexible, and the minimum range of position B is littler than umbrella rope diameter, so the umbrella rope will be stuck in B place, position, can prevent that the umbrella rope is loosening.
Embodiment two:
Referring to Fig. 4, Fig. 5, its structure of rope locking device comprises umbrella nest body 5, described umbrella nest body 5 is provided with " U " type groove 6, be provided with pulley 8 in described " U " type groove 6, the side of described U type groove 6 is provided with one and falls " V " type groove 9, umbrella rope 7 passes " V " type groove 9, and described pulley 8 is provided with sawtooth 10, and described sawtooth 4 prevents that umbrella rope 3 from sliding.
The distance of described " V " font groove 9 bottoms and pulley is greater than the diameter of umbrella rope 7, the distance of described " V " font groove 9 tops and pulley 8 is less than the diameter of umbrella rope 7, described pulley 8 can more than, sagging translation is moving, " V " type groove 9 of umbrella nest has certain angle, above big, below little, during parachute-opening, the effect of umbrella rope tension power to A to moving, move opening altitude to when the umbrella rope, the pulling force that the umbrella rope is subjected to disappears, under the effect of umbrella cover gravity, the umbrella rope moves upward, because of the frictional force between umbrella rope 7 and the pulley 8 makes pulley 8 move up with umbrella rope 7, when pulley 8 moves to certain position, the distance between pulley 8 and the following nest inwall is less than the diameter of umbrella rope 7, at this moment, umbrella rope 7 will be sandwiched between pulley 8 and the umbrella nest inwall.
