Abstract

The utility model relates to a novel manual string winder, which characterized in comprising a rocker arm and a winding coil, a string clamping device is arranged on the winding coil. The utility model is characterized in that: the winding coil is axially provided with a protrusion, the protrusion is matched with the groove arranged on the rotary body, an inner arm torsion spring is arranged at one end of the rotary body, both arms of the inner arm torsion spring are arranged between the protrusion and the groove, the inner arm torsion spring is arranged in the annular slot on the side wall of inner hole of the base, the housing is sleeved outside the winding coil, the housing is arranged fixedly with the base. The utility model has the advantages of small size, convenient operation, light mass, and reliable performance. The utility model can be widely used in various small hoisting and lifting structures.

Description

The novel manual winder

Technical field

The utility model relates to a kind of winder, particularly relates to a kind of novel manual winder that is used for various small-sized liftings, lifting structure.

Background technology

In the market, very single for the structure of manually rising progressively, rise falling unit, generally still be the structure that traditional rocking arm directly drives spool, when using this structure, when rocking arm stops operating, the spool counter-rotating, hoisting heavy can plunk down, and easily the person is damaged.

Summary of the invention

The utility model can guarantee that handle rests on the optional position in the spiral process, the novel manual winder that wire spool is nonreversible for the technical matters that exists in the solution known technology provides a kind of.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of novel manual winder, comprise rocking arm and wire spool, the card line apparatus is installed on the wire spool, described winding roll is provided with projection vertically, the groove that is provided with on described projection and the swivel is equipped, the inner arm torsion spring is installed in one end of described swivel, two arms of described inner arm torsion spring are between described projection and described groove, described inner arm torsion spring is installed in the annular groove that is provided with on the base endoporus sidewall, the outside cover casing of described winding roll, described shell and base install.

The utility model can also adopt following technical measures:

Described novel manual winder is characterized in that: an end of described rocking arm is a tetragonal body, is inserted in the endoporus of swivel.

Described novel manual winder is characterized in that: described card line apparatus is a card line pin, and described card line pin is fixed on the wire spool, is provided for installing the preformed hole of clamp nut in shell end.

Advantage and the good effect that the utlity model has are: because the utility model is equipped with the inner arm torsion spring between winding roll and swivel, when swivel stops operating that is handle when resting on the optional position, the weight that is raised or descends applies downward power to winding roll, winding roll tightens torsion spring, torsion spring applies antagonistic force to swivel, this antagonistic force passes to the projection that is provided with on the winding roll by the groove that is provided with on the swivel, thereby make winding roll keep static, realized that handle rests on the optional position in the spiral process, winding roll is nonreversible, prevent that hoisting heavy from plunking down, avoid the injury person.It is little, easy and simple to handle that the utility model also has a volume, light weight, and the advantage of dependable performance can be widely used in various small-sized liftings, the lifting structure.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 to Fig. 5, the utility model can be fixed with the connecting element bolt together by the housing 1 and the base 2 that are solidly installed.Have a circle annular groove on the base 2 endoporus sidewalls, be used to locate inner arm torsion spring 3, prevent spring 3 end float misalignments.Groove on the swivel 4 cooperates installation with projection on the wire spool 5, and two arms of inner arm torsion spring 3 are fixed, and by the rotation drive wire spool 5 and the inner arm torsion spring 3 of swivel 4, the three rotates together, with steel rope on wire spool 5, thereby hoisting heavy.If the people is for stopping operating in the coiling process, at this moment, by the effect of torsion spring 3, swivel 4 and wire spool 5 will be subjected to from inner arm torsion spring 3 with extraneous load direction opposite effect power, can guarantee that wire spool 5 is static, and then prevent that steel rope is reverse and come off.

On the wire spool 5, card line pin 6 is housed, is provided with preformed hole on housing 1 end and wire spool 5 sidewalls, the people can pass through the preformed hole clamp nut, and is with card line pin that one end and the wire spool 5 of steel rope is tightly fixing.

One end of rocking arm 7 is tetragonal bodies, is inserted in the endoporus of swivel 4, can rotate together.After coiling finished, rocking arm can take out independent placement easily.Reduce to take up room and reduce hidden danger.

Claims
