Description

Strainer

A kind of fixing, tighten device that is used for the goods transport industry, the tension of bandage is with fixing when being mainly used in goods transport.

At present during the carrier shipping goods goods fixing, tighten is many with rope or iron wire, adopts manual manpower tension, time-consuming, effort is taken a lot of work again, is difficult to accomplish safe and reliable.

The purpose of this utility model provides a kind of efficient, laborsaving, failure-free bandage take-up device, is used for the fixing of carrier goods and binding, and can be used as travel simple and easy traction appliance when running into contingency in the way of dilly.

The utility model is made up of framework, spool, ratchet device, rocking arm handle and bandage and hook etc., it is characterized in that bandage is twisted on the ratchet shaft, utilize ratchet device rolling-in and fixing bandage, its structure is that one of framework connects the bandage hook, and there is a pair of spool hole the other end; One on rocking arm handle has handgrip, and a pair of spool hole is also arranged on the other end; Spool is that semi-moon shaped first quarter moon axle is formed by a pair cross-section, the a pair of half moon axis hole that separates is respectively arranged on two ratchets, and be contained between framework and the rocking arm handle spool hole, spool passes the rocking arm handle, spool hole on ratchet and the framework is linked together them, spool two ends dowel fixes, the two halves spool is fixedly separated by the axis hole on the ratchet, form the slit that to insert tied lead in the middle of the spool between the framework, the ratchet check plate is housed; on the rocking arm handle ratchet swinging plate is housed; the handle of release is arranged on the swinging plate on the framework, front end has the release of ratchet check plate to promote projection outside the rocking arm handle spool hole, and there is the check plate latch hook side.Framework and rocking arm handle all assemble with the steel plate punching press, framework both sides and rocking arm handle both sides have check plate chute and swinging plate chute respectively near ratchet axis hole place, check plate and swinging plate are contained in respectively in its chute and form ratchet device jointly with ratchet, and check plate and swinging plate are all pressed to ratchet with spring.During use, pull rocking arm handle back and forth, under the effect of swinging plate and check plate, the ratchet one-way rotation, with the bandage rolling-in on spool.In the time will unclamping fixture, just it is thrown off with ratchet with pulling release handle on the swinging plate, pulls the rocking arm handle then and makes nearly 180 degree of itself and framework flare up, and the release promotion of its front end is protruding to be pushed check plate open from ratchet, and bandage can unclamp from spool.

The utility model is small and exquisite portable, and is easy to use, and rapid operation is strained solid and reliable.

Accompanying drawing 1 is the main diagrammatic sketch of the utility model structure.

Accompanying drawing 2 is the diagrammatic sketch of bowing of the utility model structure.

Whole strainer is made up of framework 9, spool 6, ratchet device, rocking arm handle 1 and bandage 10 and hook ¨ etc., and framework 9, rocking arm handle 1, ratchet 4 and check plate 8, swinging plate 3 all form with punching of the steel plate, and through bakingout process.9 one of frameworks connect bandage hook 11, and there is a pair of spool hole the other end; Rocking arm shakes hands 1 one handgrip 14 is arranged, and a pair of spool hole is also arranged on the other end; Spool 6 is that semi-moon shaped first quarter moon axle is formed by a pair cross-section, the a pair of half moon axis hole that separates is respectively arranged on two ratchets 4, and be contained in framework 9 and rocking arm is shaken hands between the 1 spool hole, spool 6 passes rocking arm handle 1, spool hole on ratchet 4 and the framework 9 is linked together them, spool 6 two ends are fixing with pin 5, two halves spool 6 is fixedly separated by the axis hole on the ratchet 4, form the slit that to insert tied lead in the middle of the spool 6 between the framework 9, be equipped with on the framework 9 on the ratchet check plate 8 rocking arms handle 1 ratchet swinging plate 3 is housed, have on the swinging plate and discharge handle; the rocking arm outer front end in 1 spool hole of shaking hands has the ratchet check plate to discharge to promote protruding 7, and there is check plate latch hook 2 side.Framework 9 has check plate chute and swinging plate chute with the both sides of rocking arm handle 1 respectively near ratchet axis hole place, check plate 8 is contained in respectively in its chute with swinging plate 3 and forms ratchet devices jointly with ratchet 4, and check plate 8 is pressed to ratchet 4 with spring 12,13 respectively with swinging plate 3.During use, hook 11 is fixing, and other bandage 10 1 ends are fixed, and insert in the spool seam with pulling the other end, pulls the rocking arm handle back and forth, under swinging plate 3 and check plate 8 act on, ratchet 4 unidirectional rotation, with bandage 10,15 rolling-in on spool 6.Rocking arm handle 1 and framework 9 are lumped together, and latch hook 2 blocks check plate 8, can prevent that accident from unclamping.In the time will unclamping fixture, with the release handle that pulls on the swinging plate 3 itself and ratchet 4 are thrown off, pull rocking arm handle 1 then itself and framework 9 flare ups nearly 180 are spent, the release promotion projection of its front end/check plate 8 is pushed open from ratchet 4, bandage 10 can unclamp from spool 6.
