Abstract

The invention discloses a tense automatic lockfast rope clasper. A rope (10) wound on a gliding cylinder (1) is drawn in a circular arc-shaped groove body (5) by the gliding cylinder (1) which is limited within a certain range, the occlude of the gliding cylinder (1) and the circular arc-shaped groove body (5) with the rope is closer with the increase of pull, and the tightening effect of the rope is more remarkable. When the upper end rope (10) is pulled back and the rope wound on the gliding cylinder is released to be conveyed downwards, the utilization length of the rope is shortened, and conversely, the utilization length of the rope is stretched. Therefore, the length of the rope can be adjusted and the rope can be locked in the rope clasper automatically and firmly by the pull without any tools to reach the aims of no harm of the rope, simple structure and flexible and convenient assembly and disassembly.

Description

Tensioning and automatic locking rope fastener

Technical field

The present invention relates to a kind of rope and buckles, particularly a kind of tensioning and automatic locking rope fastener.

Background technology

The present invention is number to be 200720189833.2 for I have invented undocumented utility model application, title is the tensioning and automatic locking rope fastener that a kind of fall arrest automatically locks designed configuration on the safety rope, also is suitable for the fastening of rope such as other steel wire rope and needs the adjustment of length.

Summary of the invention

The present invention realizes as follows: it is that a circular hole (being called for short the sliding cylinder body) is respectively bored at the cylinder body two ends that are processed with the matrix groove at position, a stage casing, with two holes of this body settle be enclosed within for rectangle two long limits be on the columned cylinder, the rectangle front end takes over and bores a wire rope handling circular hole, the inboard is processed into depression and is circular-arc, have male and female face in the circular arc, opposite rear end sidetracking one bridle port of taking back, the lower end comes directly towards face down bonding one annulus that takes over, so far the rope head is passed the bridle port on the matrix arc groove earlier, to several weeks, pass the corresponding bridle port in lower end around chase groove sliding cylinder body one, to fix a latch nook one passes fixed body together with latch nook circular hole on the rope top, on the annulus on its top, rear portion, can arbitrarily adjust length and fastening sling this moment with the latch nook hook lock.When retracting the rope that the upper end rope unclamps on the sliding cylinder body it is down sent, the total length that rope is utilized will shorten, otherwise the length of always utilizing of rope will be extended.The cylinder moving body is adjusted at the top gets close to the circular arc cell body, when pulling upper end fly rope makes the stressed tension of integral body, the sliding cylinder body also will be along the both sides cylinder together with being drawn in automatically in the circular arc cell body around rope thereon, and both just close more to the rope jam-packed with the increase that is subjected to pulling force, degree to the rope fastening is just more firm, because of two holes of cylinder slide mass are to be enclosed within on the rectangle two long limit cylinders, and can only slide within it, the effect of male and female face and the mutual frictional force of rope is all arranged because of in the arc groove and sliding cylinder surface again, make its interlock non-skid property stronger, do not use any instrument to finish and adjust the operation that rope uses length and stressed automatic locking jail rope, and do not damage rope, use simple and convenient flexibly

Rope of the present invention is buckled by the purposes scope of application can make the different goods of size specification, is not only applicable to a kind of fall arrest and automatically locks safety rope, and be more suitable for the engineering use of frequent mobile installing/dismounting.Use can be removed the latch nook of its rope rear end when a kind of fall arrest automatically locks safety rope, the rope head directly is fixed on the annulus of tensioning and automatic locking rope fastener lower end fixed body.

Description of drawings

Below in conjunction with embodiment the present invention is done progressive explanation.

Fig. 1 is a front elevational schematic of the present invention.Fig. 2 is the front view of Fig. 1 (5) arc groove.

(1), sliding cylinder body among Fig. 1, (2), move left and right hole, (3), left and right sides cylinder, (4), the preceding bridle port of wearing, (5), the arc groove body, (6), after wear bridle port, (7), rear end annulus, (8), latch nook, (9), fixed body annulus, (10), rope.

The specific embodiment:

In Fig. 1, rope (10) is passed preceding bridle port (4) and after the sliding cylinder body passed after (1) one to several weeks, wears bridle port (6), rope (10) lower end fix a latch nook (8), with its pass in the lump fixed body annulus (9) with latch nook (8) hook lock on rear end annulus (7).When retracting upper end rope (10) and unclamp rope in cylinder mobile it is down sent, the total length that rope is utilized will shorten, otherwise the total length that rope is utilized will extend, sliding cylinder body (1) is adjusted near arc groove body (5), when pulling upper end rope (10) makes the stressed tension of integral body, sliding cylinder body (1) left and right sides, two ends circular hole is subjected to it to place the cylindrical restriction in the left and right sides, with sliding cylinder body (1) together with around on rope draw in the arc groove automatically, and both just close more to the rope jam-packed with the increase that is subjected to pulling force, fastening effect is just outstanding more.

Claims

1. tensioning and automatic locking rope fastener, comprise sliding cylinder body (1), be processed with the matrix groove at position, sliding cylinder body stage casing, a circular hole (2) is respectively bored at sliding cylinder body two ends, the two holes arrangement of sliding cylinder is enclosed within on the rectangle cylinder, two long limits of described rectangle cylinder are cylinder (3), the rectangle front end is worn bridle port (4) before taking over and boring one, arc groove body (5) is processed in rectangle front end inboard, have male and female face in the circular arc, opposite rear end is taken back and is worn bridle port (6) behind the sidetracking one, and top, lower end face down bonding one annulus (7) that takes over passes preceding bridle port (4) earlier with the rope head, after passing to several weeks, sliding cylinder body one wears bridle port (6), fix a latch nook (8) with on the rope top, latch nook passed fixed body annulus (9) in the lump, with latch nook (8) hook lock on annulus (7):

When retracting upper end rope (10) and unclamp rope on the sliding cylinder body it is down sent, the total length of rope utilization will shorten, otherwise the total length that rope is utilized will extend, sliding cylinder body (1) is adjusted near arc groove body (5), when pulling upper end rope (10) makes the stressed tension of integral body, sliding cylinder body (1) two ends circular hole is subjected to it to place the restriction of left and right sides cylinder (3), with sliding cylinder body (1) together with around on rope draw in automatically in the arc groove body, and both just close more to the rope jam-packed with the increase that is subjected to pulling force, its fastening effect is just outstanding more.
