Abstract

The utility model provides a novel Y-shaped braid belt buffer, which comprises an outer layer braid belt, a Y braid belt and a sheath, wherein the single-layer braid belt at the branched part of the Y braid belt is formed through weaving warp yarn and weft yarn structures, warp yarns are divided into two kinds, the one-back-stitch and one-knit stitch weaving is adopted between the first kind of warp yarns and weft yarns, the three-back-stitch and one-knit stitch weaving is adopted between the second kind of warp yarns and the weft yarns, and two staggered second kinds of warp yarns are spaced at every two first kinds of warp yarns. For the two-layer braid of the Y-shaped braid belt, each sewing thread and the weft yarns of the Y braid are woven together by adopting the two-back-stitch and two-knit stitch mode. The novel Y-shaped braid buffer is usually used for being matched with a safety belt restrained in the human body waist position to be used; and a novel weaving method of the Y braid is adopted, the single side stress of the Y braid is avoided, the impact strength can be better absorbed, the buffer effect is realized, and the fall injury of users can be better prevented.

Description

Novel Y type ribbon buffer

Technical field

The utility model relates to the buffer technology field, is specifically related to a kind of novel Y type ribbon buffer.

Background technology

In order to guarantee high-altitude activity or operating personnel's safety, the work high above the ground personnel have worn the safety rope device on one's body usually, and have worn buffer on safety rope usually, a kind of Y type ribbon of normal use on the described buffer.As user aloft when operation such as building, elevator reparing, shipbuilding etc.; when down dropping accidentally, the Y type ribbon of buffer can be torn to absorb and impact strength, with the gravity speed that reduces down to drop again; reach cushioning effect, thereby the user is produced the safeguard protection effect.Y type ribbon in the past is because of the reason of weaving method, when being used with the safety belt that is bound by position, human lumbar border, because Y type ribbon is about 90 once torsion modes when stressed, rather than we directly are the power of pullling of tearing of about 0 degree, be easy to cause Y type ribbon monolateral stressed and directly twist off, thereby can't absorb impact strength really and play cushioning effect, so can't accomplish to guarantee to protect user's effect.

Summary of the invention

At above problem, the utility model provides a kind of can prevent the monolateral stressed and novel Y type ribbon buffer that directly twists off of Y type ribbon.

The technical scheme that its technical problem that solves the utility model adopts is: this novel Y type ribbon buffer comprises outer ribbon, Y ribbon, sheath; Be folded to described sheath inside behind described outer ribbon and the Y ribbon sewing, its two ends are stretched out jacket portions and are linked to each other with connector; The double-deck ribbon of described Y ribbon uses suture to be woven together; The individual layer ribbon of described Y ribbon crotch adopts the braiding of longitude and latitude knot structure to form, its warp is divided into two kinds, braiding one on the other between first kind of warp and the parallel, (be upwards parallel of bending parcel of each first kind of warp, parallel of each parcel of bending downwards), between second kind of warp and the parallel on three braiding once (be upwards three parallels of bending parcel of each second kind of warp, parallel of each parcel of bending downwards), be separated with second kind of warp of two dislocation between between per two first kind of warps.

As preferably, the double-deck ribbon of described Y ribbon, adopt on two mode under two be woven together (being upwards two parallels of the every limit of bending parcel Y ribbon of each suture, two parallels of the every limit of each parcel of bending downwards Y ribbon) between every suture and the described Y ribbon parallel.

The beneficial effects of the utility model are: this novel Y type ribbon buffer is commonly used to be used with the safety belt that is bound by position, human lumbar border; By the novel weaving method of Y ribbon, when the work high above the ground personnel fell, what the Y ribbon was about 0 degree tore the power of pullling, and has avoided the Y ribbon monolateral stressed, can better absorb to impact strength and play cushioning effect, better prevented user's tumble injury.

The specific embodiment

Further specify below in conjunction with the utility model of embodiment:

Shown in embodiment among Fig. 1, this novel Y type ribbon buffer comprises outer ribbon 1, Y ribbon 2, sheath 3; Be folded to described sheath 3 inside behind outer ribbon 1 and described Y ribbon 2 sewings, the part that sheath is stretched out at its two ends links to each other with connector; The double-deck ribbon 4 of described Y ribbon 2 uses suture to be woven together.As shown in Figure 2, the individual layer ribbon of described Y ribbon 2 crotches adopts the braiding of longitude and latitude structure to form, be warp 21 vertically, 22,23, be parallel 24 laterally, wherein said warp 21,22,23 are divided into two kinds, braiding one on the other between first kind of warp 21 and the parallel 24 (is upwards parallel 24 of bending parcel of each first kind of warp 21, parallel 24 of each parcel of bending downwards), second kind of warp 22,23 and parallel 24 between on three braiding once (be each second kind of warp 22,23 upwards bend three parallels 24 of parcel, parallel 24 of each parcel of bending downwards), be separated with second kind of warp 22 of two dislocation between between per two first kind of warps 21,23.

This novel Y type ribbon buffer is commonly used to be used with the safety belt that is bound by position, human lumbar border; Described sheath 3 is fixed on the safety belt that twines the person, two connectors on described outer ribbon 1 two ends, and one links to each other with fixture with connector by ribbon, and one and safety belt are fixed, and the schematic perspective view when described Y ribbon 2 is not torn is as shown in Figure 3.When the work high above the ground personnel fall, the tear place 4 of described Y ribbon 2 can be torn; As shown in Figure 4, what the suture of Y ribbon 2 double-deck ribbons 4 can not stopped pulls apart, thereby has offset the impact strength when the work high above the ground personnel fall.The novel weaving method of this Y ribbon, what make that the Y ribbon is about 0 degree tears the power of pullling, and has avoided the Y ribbon monolateral stressed, can better absorb to impact strength and play cushioning effect, better prevents user's tumble injury.

As shown in Figure 5, the double-deck ribbon 4 of described Y ribbon, adopt on two the mode sewing (being upwards two parallels 24 of the every limit of bending parcel Y ribbon 2 of each suture 5, two parallels 24 of the every limit of each parcel of bending downwards Y ribbon 2) under two between every suture 5 and the described Y ribbon parallel 24.This suture 5 has effectively guaranteed the applying on Y ribbon 2 both sides, has improved the impulse force that consumes when tearing.
