Abstract

The utility model discloses a loop fixer, which is composed of a fastener and a rope cappel. The fastener includes a rack body and an eccentric cam fixing one end of the rack body and a slide arranged on the rack body; the slide is provided with an eccentric cam, a transmission gear and a ratchet wheel; the transmission gear is engaged with the rack; the transmission gear revolves and drives the slide to move to the left side; a spring is arranged between the handle at the back on the ratchet wheel and the slide; the slide is prevented from moving to the right side by the self-gravity of the ratchet wheel and the thrust of the spring. The rope cappel includes a lock sleeve and a wedge-shaped pin. Two ends of the loop binding the article are inserted into the lock sleeve, tensioned and fastened by the fastener. The loop fixer is characterized in that the tension of the loop in operation is largely increased, and the loop is easy to loosen; the experiment shows that when the loop is snapped, two pieces of rope cappel in the lock sleeve do not move a little; so that the loop fixer is safe, reliable with high efficiency and simple operation.

Description

The tight rope fixer

Technical field:

The utility model relates to a kind of goods securing device, specifically a kind of when cargo handing the required tight rope fixer of binding.

Background technology:

Behind the cargo handing when binding two ropes the method that is connected and fixed of two fag ends of tension is a lot of relatively, but defectiveness is all tied up fast knot as strain back two fag ends with manpower, the method tightness is not enough, the place of knotting is easily from pine or dropout; Also useful machinery tension back tightens with a plurality of U-shaped clamps, and the method inefficiency, every clamp need manually tighten with two nuts, because the intensity of screw thread is limited, do not guarantee required pulling force.

Summary of the invention:

In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of simple in structure, easy to operate, efficient is high, fastening strength is big tight rope fixer.

The purpose of this utility model is achieved in that it is made of fastener and wire clips two parts, it is characterized in that: fastener comprises the tooth bar body and fixes the eccentric cam of this tooth bar body one end and be located at slide block on the tooth bar body, this slide block is provided with eccentric cam and transmission gear and ratchet, the driving cog wheel and rack is meshed, move to the left by rotating transmission gear drive slide block, be provided with spring between rear portion spanner and the slide block on the ratchet, the ratchet front portion is provided with the ratchet that is meshed with tooth bar, makes click stop slide block to move to the right under self gravitation and spring thrust effect; Wire clips comprises the taper of cutting ferrule and penetrable cutting ferrule.

For making things convenient for rope to put, be provided with the rope seat in tooth bar body one end eccentric cam bottom and slide block one end eccentric cam bottom.

Loosening for preventing taper, penetrate cutting ferrule one side at taper and be provided with the perforation that penetrates spring cotter.

Behind the cargo handing, rope one termination of restraint of loads is inserted in the cutting ferrule, and rope is compressed by this end eccentric cam, another termination of rope is pushed down by eccentric cam on the slide block, rotary transmission gear moves slide block to the left then, drives the rope termination and inserts in the cutting ferrule and tighten up a rope, and throws in the cutting ferrule between two ropes with taper then, two ropes are risen outward, two ropes are fixed with this.At last fastener is removed, for next time fastening rope standby, wire clips is transported with goods.

The utility model has the advantages that the tightening force of restricting improves greatly in operation, and be difficult for looseningly, the experiment proved that even rope is broken, two ropes in the wire clips cover also have not a particle of mobile, thus safe and reliable, efficient is high, simple to operate.

Below in conjunction with accompanying drawing the utility model is done with explanation.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is an A-A view among Fig. 1;

Fig. 3 is the left view of Fig. 2.

The specific embodiment:

With reference to the accompanying drawings, the utility model is made of fastener and wire clips two parts.Wherein fastener is made of tooth bar body 13, eccentric cam 20, slide block 10, eccentric cam 15, transmission gear 16, ratchet 18.Eccentric cam 15, transmission gear 16 and ratchet 18 are respectively by wheel shaft 12, gear wheel shaft 11 and ratchet shaft 9 are arranged on the slide block 10, be provided with spring 8 on the ratchet 18 between rear portion spanner 7 and the slide block, ratchet 18 front portions are provided with the ratchet 17 that is meshed with tooth bar 13, make click 17 under self gravitation and spring 8 thrust, stop slide block 10 to move to the right, transmission gear 16 is meshed with tooth bar 13, can drive slide block 10 by rotation transmission gear 16 and move to the left, rope seat 19 and 14 is located at tooth bar body one end eccentric cam, 20 bottoms and slide block 10 1 end eccentric cams 15 bottoms respectively.Wire clips partly comprises the taper 4 of cutting ferrule 5 and penetrable cutting ferrule and prevents the spring cotter 6 that taper 4 becomes flexible.Specific operation process is: rope one termination 3 of restraint of loads is inserted in the cutting ferrule 5, and rope is compressed by this end eccentric cam 20, another termination 21 of rope is pushed down by eccentric cam 15 on the slide block 10, by gear wheel shaft 11 square end head rotary transmission gears 16 slide block 10 is moved to the left then, drive rope termination 21 is inserted in the cutting ferrules 5 and is tightened up a rope, throw between cutting ferrule 5 interior two

ropes

3,21 with taper 4 then, two

ropes

3,21 are risen outward, two ropes are fixed with this.Loosening for preventing taper 4, penetrate cutting ferrule 5 one sides at taper 4 and be provided with the spring cotter 6 that penetrates perforation.At last fastener is removed, for next time fastening rope standby, wire clips is transported with goods.
