Abstract
The invention discloses a rope fastener which comprises a body, a first belt threading member and a second belt threading member, wherein the first belt threading member and the second belt threading member are rotatably connected with the body; the rotation axes of the first belt threading member and the second belt threading member are not superposed; the first belt threading member and the second belt threading member are provided with a rod-shaped elastic part on one side away from the body; the first belt threading member passes through the space between the rotation axis of the second belt threading member and the elastic part of the second belt threading member from one side away from a binding object, of the second belt threading member, toward one side close to the binding object; when the first belt threading member and the second belt threading member rotate toward one side close to the binding object, the elastic part of the second belt threading member gradually approaches the elastic part of the first belt threading member until a rope clamping belt; and when the first belt threading member and the second belt threading member rotate toward one side away from the binding object, the elastic part of the second belt threading member gradually leaves the elastic part of the first belt threading member until the rope is released. The rope fastener has a simple structure and reliable action, and is widely used for tensioning ropes such as shoelaces and the like.
Description
Technical field
The invention belongs to the sling technical field, relate in particular to a kind of rope body fastener.
Background technology
Rope body fastener has been paid close attention to because of its convenience has received everybody particularly inconvenient both hands tether band crowd since emerging widely.But existing rope body fastener major part has and is not easy to fasten, fasten the loosening easily problem in back.
Chinese patent CN101596032A discloses a kind of fast free strainer, and pedestal, linking closely and releasing is formed by connecting, linking closely and releasing is through respectively in the perforation of pedestal, releases greater than linking closely, and links closely to be semicircle; Release to rectangle and an end are the circular-arc rake angle that up has, a transverse axis is arranged in the centre of releasing, transverse axis has a roller outward; The urgent side of detaining of the free end of belt passes through to the top of releasing and walks around roller, passes from the centre of releasing and linking closely again.The free end of tension belt is then fastened belt.It is very high that but the transverse axis of this device and the cooperation position that releases require, if transverse axis is too bored a hole near pedestal, this rope body is not easy tension, if transverse axis too near the outside of releasing, is not easy to unclamp after the system of then restricting is tight.The complex structure of this device, processing difficulties simultaneously, cost is higher.
BP file GB2321666 discloses a kind of belt jockey, and it comprises the connection main body, upward ring hinged with being connected main body and following ring; The said ring and continuous of going up near the hinged seat that is connected main body; Following ring links to each other with hinged seat away from central shaft, because last ring is with the ring size is identical down, encircles free end and encircles when passing from following when rope penetrates from ring and the overlapping hole of ring down to walk around; If spur rope band downwards; Pass the hole and increase gradually, rope band can not be fastened, and could strain belt so can only upwards spur.This tension mode is not easy to fasten rope band, because after rope band is fastened, this device two ends under free state are downward, if rope band can be easy to become flexible during with said apparatus, does not have the effect of frenulum.
Summary of the invention
Technical problem to be solved by this invention provides the automatic take-up of a kind of rope band that can reliably fasten.
For realizing above-mentioned purpose; The invention provides a kind of rope body fastener, it comprises, body; First wears band part and second wears band spare; Respectively rotatingly is connected with body, said first wears band part and said second wears and is with the pivot center of part not to overlap, and said first wears and be with part and said second to wear to be with part to have a shaft-like elastic part in the side away from said body; Said first wear the band part from said second wear the band part the side away from a lateral approach binding of binding pass second wear the band part pivot center and second wear the space between the elastic part of being with part; Said first wears band part and second wears the band part when rotating near binding one side, said second wear the band part elastic part move closer to said first and wear the elastic part of being with part, until the locked position that can clamp rope band; Said first wears band part and second wears the band part when rotating away from binding one side, and said second wears the elastic part of being with part wears the elastic part of being with part away from said first gradually, until the unlocked position that can unclamp rope band.
This rope body fastener also comprises pulls the unit, said pull unit and said first wear the band part be connected, be used to pull said first and wear band spare, rope band is unclamped.
In said body both sides, be respectively equipped with body rotating respectively be connected first wear the band part and second wear band spare.
Said first wear the band part pivot center away from the end of said body near the rope band draw direction, said second wear the band part pivot center near said body near the end of rope band draw direction.
Said first wear the band part pivot center than said second wear the band part pivot center away from said binding.
Said first wears the structure of being with the said relatively body of part to rotate comprises that being arranged on said first wears first hinge hole on one of band part or said body and be arranged on first jointed shaft on both relative parts, and said first jointed shaft is arranged in first hinge hole rotationally;
Said second wears the structure of being with the said relatively body of part to rotate comprises that being arranged on said second wears second hinge hole of being with on one of part or said body; With second jointed shaft that is arranged on both relative parts, said second jointed shaft is arranged in said second hinge hole rotationally.
Said first wear the band part and said second wear the band part separately with corresponding said body on pivot center part looping structure.
Said first wears the length of being with part wears the length of being with part greater than said second.
It is the short end away from said binding one side that said body is one, near the trapezoid support of binding one side for the long end.
Said first wears the band part has spacing bending upwards in the side away from said body.
Said first wears the band part is provided with sewing hole in the side away from said body, is used for sewing up with the said unit of pullling.
The present invention has following advantage:
Rope band fastener of the present invention comprises the band spare of wearing of body and at least two relative body rotations; Through one wear the band part from another wear in the band part framework from away from binding to the connected mode that passes near the binding direction; Make this fastener when frenulum; Passing the hole can dwindle gradually, till fastening rope band.Simultaneously, this fastener is with part just can reach the purpose that rope band gets loose through upwards spurring to wear.This frenulum mode is fastened rope band easily, and when upwards the pulling force of band part was not worn in pulling after rope band was fastened, this fastener was not easy to become flexible.
Preferably, two of the present invention to wear the band part all be to be connected with body through hinged mode, wears and be with the rotation space of part very big; During frenulum, can turn to position, after fastening with the rope band locking always; This device under nature be two wear the band part downward; Pass Kong Buhui and become big, than the rope body fastener of prior art, this rope band of fastening is not easy to get loose.
Simultaneously, rope band buckle structure of the present invention is simple, and cost of parts and processing and manufacturing cost are all very low, can be widely used in the degree of tightness of rope bodies such as shoestring.
