Description

Rope tightening device

Technical Field

The utility model relates to a machinery euphroe equipment field especially, relates to a euphroe.

Background

After the automobile is loaded with goods, the goods are usually fastened to the automobile by using ropes, the fastening of the ropes is usually pulled manually, and the manual rope tightening has the defect of small strength and difficulty in fastening the goods, so people invent the rope tightening device, and the ropes firmly fasten the goods through the rope tightening device.

The euphroe on the existing market generally is equipped with a string rope hook on the spool, but this kind of string rope hook can't be adjusted in the position on the spool, brings inconvenience for the user. At the in-process of tightrope, the rope is located the spool middle part and hangs the rope hook just right, and this is the optimal operating condition, but under most of the circumstances, the rope of fixed goods often deviates from the middle part of spool, then the rope can only be partial to spool one side winding, leads to the rope all to twine in one side, because the distance between string rope hook and the pedestal is less relatively, will rub with the both sides of pedestal very fast before the rope is still stopped tightly sometimes, makes people tightrope more hard.

In addition, in operation, when people wind the rope, people find that sometimes the ratchet wheel is required to rotate by one tooth socket width to tie the goods more tightly, and due to the limitation of the tooth socket distance, the ratchet wheel can only rotate by a distance of partial tooth socket width, and cannot rotate by the distance of one tooth socket width, so that the rope is loosened slightly.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.

Examples

The utility model provides a euphroe, it is shown with reference to fig. 1 and fig. 2, the utility model discloses a euphroe, including pedestal 1 and spool 2, the both ends of spool 2 are rotated and are installed on pedestal 1 and the part is stretched out, are equipped with spout 3 on spool 2, install in the spout 3 and hang rope hook 4, are equipped with first ratchet 5 and second ratchet 6 on the both ends of spool 2, and first ratchet 5 and second ratchet 6 misplace respectively and set up on spool 2, still articulate two on the pedestal 1 have with first ratchet 5, second ratchet 6 complex pawl 7.

The bobbin 2 is the hollow tubular structure, hangs rope hook 4 and can remove in the spout 3, and when the rope of fixed goods was located the middle part of bobbin 2, hang rope hook 4 and can be in the spout 3 in any position all can, and at the tight rope in-process, the rope is difficult to rub with the both sides of pedestal 1, and this is more ideal operating condition. If the rope that tightly stops the goods deflects left, then need to hang rope hook 4 and move to the right-hand member, and then with rope system at rope hook 4, rotate spool 2, the rope is from the right side to left side at the orbit in-process and is close to the center and the left side of spool 2 gradually, and the left side distance of rope hook 4 and pedestal 1 is longer this moment, and under most circumstances, when the rope has not contacted the left side of pedestal 1 yet, the rope just stopped tightly. In a similar way, if the rope of tight goods of stopping in reverse inclines right, then need will hang rope hook 4 and move to the left end, is hanging rope hook 4 with the rope system again, rotates spool 2 and carries out the tightrope, and the rope is also difficult for contacting the right side of pedestal 1, makes people's tightrope more light.

Referring to fig. 3, the first ratchet wheel 5 and the second ratchet wheel 6 are respectively arranged on the winding shaft 2 in a staggered manner, and in the rope tightening process, when people rotate the winding shaft 2, the first ratchet wheel 5 and the second ratchet wheel 6 are arranged in a staggered manner, so that the first ratchet wheel 5 and the second ratchet wheel 6 are intermittently matched with the pawl 7 to prevent the winding shaft 2 from reversing, the distance of one tooth space width per rotation is reduced, sometimes, people want to rotate one tooth space width which cannot be reached, and the tooth space width is easier, so that the rope can be tightened. In addition, sometimes one of the first ratchet wheel 5 and the second ratchet wheel 6 is damaged, and the rope tightener can be used continuously, so that the reliability is good.

The first ratchet wheel 5 and the second ratchet wheel 6 are both welded with shaft heads 8, and the shaft heads 8 are provided with jacks 9. Can satisfy people and insert two jimmy simultaneously, two people rotate the jimmy together and do all can a bit more, can make the tight of rope receipts.

One end of the sliding chute 3 is provided with a first accommodating groove 31, the other end of the sliding chute 3 is provided with a second accommodating groove 32, and the middle part of the sliding chute 3 is provided with a third accommodating groove 33. The first receiving groove 31, the second receiving groove 32 and the third receiving groove 33 are all for further preventing the rope hook 4 from slipping along with the increase of the rope tension in the rope tightening process.

Referring to fig. 2, the first receiving groove 31 and the second receiving groove 32 are L-shaped and are symmetrically disposed on the sliding chute 3. The structure of L shape, can more effectually prevent to hang sliding of rope hook 4, if the rope of tight goods of stopping skews left, need will hang rope hook 4 when moving to the right-hand member, people can move D department in second storage tank 32 with hanging rope hook 4 this moment, be on hanging rope hook 4 with the rope system again, rotate spool 2, because the rope can be around the in-process to hang rope hook 4 toward the left-hand draw, because the structure of this L shape, even make hanging rope hook 4 receive the pulling force that is bigger again can not slide yet. Similarly, if the rope for tightly braking the goods is deflected to the right, at this time, the user can move the rope hook 4 to the position E in the first accommodating groove 31, and then the rope is tied to the rope hook 4.

Referring to fig. 4, the rope hook 4 is threaded with a first nut 10 and a second nut 11. The first nut 10 plays a role in fixing the rope hook 4, and when the rope hook 4 needs to be moved, the first nut 10 is loosened. The second nut 11 plays a role in preventing the rope from falling off to a certain extent, and when the rope is fixed through the rope hanging hook 4, the second nut 11 can hook the rope part, so that the rope is not easy to fall off; when people install the rope hook 4, the first nut 10 and the second nut 11 are firstly detached, then the rope hook 4 is put into the winding shaft 2 from two sides of the winding shaft 2, the shaft part of the rope hook 4 extends out to screw the first nut 10, and then the second nut 11 is screwed.

Referring to fig. 2, a distance a from the left end of the sliding chute 3 to the left side of the seat body 1 is the same as a distance B from the right end of the sliding chute 3 to the right side of the seat body 1, and both a and B are 1-3 cm. When the distance is too small, the rope is easy to contact the seat body 1, and when the distance is too large, the length of the sliding groove 3 is reduced, the rope cannot be effectively prevented from contacting two sides of the seat body 1, so that the optimal distance is between 1 cm and 3cm for A and B.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
