Abstract
The utility model discloses a winder. The winder comprises a winding seat and a winding reel which is rotatably arranged on the winding seat, and the winder is characterized by also comprising a limiting wheel which is coaxial with the winding reel and is fixedly installed on the winding reel, a plurality of wedged projections are uniformly arranged on the outer circumferential wall of the limiting wheel, a pivot on the winding seat is provided with a limiting strip, and a free end of the limiting strip pushes against the projections. According to the winder, the original structure by utilizing the friction force of a roller is improved, and a ratchet wheel structure is used for realizing the single-direction rotation. Compared with the original design, the weaknesses that the friction force needs to be precisely controlled, the requirement on the spring is high, the roller is easy to age and the service life is short can be avoided. The winder has the advantages of simplicity in structure, long service life, low cost and the like.
Description
Technical field
The utility model relates to a kind of winder, especially the winder on dust catcher.
Background technology
Dust catcher conventionally can be with a very long power line, to increase cleaning range.Power line, when not using, furls on winder; During use, the pulling by user can pull out elongation from winder, is convenient to cleaning; Finish using, by the button furling, can be by power line automatic rolling to winder.The work of electric power wire rolling, normally drives the reel of winder to rotate to realize by wind spring at present.When dust catcher is worked, reel must stop operating, and avoids its automatic takeup, brings inconvenience; And when user pulls power line, reel must be able to rotate again.When furling button and do not press, reel can only one-directional rotation (being called forward rotation); Press while furling button, reel automatic reverse rotates, and furls work.At present, the device of realizing above function is that a position-limited wheel is set on reel, a roller is resisted against on the periphery wall of position-limited wheel under the elastic force effect of spring, frictional force between roller and position-limited wheel is greater than the elastic force that wind spring drives reel to rotate, thereby by frictional force, limits the rotation of position-limited wheel.When user pulls power line, its motive force is greater than the elastic force of frictional force and wind spring, thereby makes reel forward rotation, thereby pulls out power line.Press while furling button, by a lever construction, make roller leave position-limited wheel, thereby frictional force disappears, the elastic force of wind spring drives reel to rotate backward, and carries out the operation that furls of power line.Although above structure is simple and easy to use, the frictional force size requirements between its pair roller and position-limited wheel is higher, and after the use through long-term, the material of roller is easily aging, and the frictional force between itself and position-limited wheel is diminished, and causes winder malfunctioning; The elasticity of this outer spring reduces, and also easily causes winder malfunctioning, thereby has reduced consumer's experience.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of winder of simple in structure, long service life.
The technical solution of the utility model is to provide a kind of winder, it comprises spiral seat and can be rotatably set in the reel on described spiral seat, it is characterized in that: it also comprises that one is coaxial and be fixedly mounted on the position-limited wheel on described reel with described reel, on the periphery wall of described position-limited wheel, be evenly provided with several wedge shape lug bosses, described spiral seat head lamp brush guard pivot arranges a positive stop strip, and a free end of described positive stop strip is resisted against on described lug boss.
Preferably, the pivoting point that described positive stop strip is connected with described spiral seat is arranged on the middle part of described positive stop strip, and another free end of described positive stop strip connects described spiral seat by a stage clip.
Preferably, it also comprises a wind spring coaxial with described reel, and one end of described wind spring is fixed on described spiral seat, and the other end is fixed on described reel.
Preferably, a columniform erection column is set on described positive stop strip, described stage clip one end is enclosed within on described erection column, and the other end is resisted against on described spiral seat.
Preferably, be provided with a circular hole running through on described spiral seat, described circular hole is provided with a rotating shaft by bearing, and described reel is arranged in described rotating shaft.
Winder of the present utility model has improved the former structure of utilizing roller frictional force, but utilizes a ratchet structure to realize one-directional rotation.It is with respect to former design, has avoided needing accurately controlling frictional force size, high to spring requirement, the roller shortcomings such as easily aging, service life is short.Have simple in structure, long service life, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of winder of the utility model most preferred embodiment;
Fig. 2 is the decomposition texture schematic diagram of a kind of winder of the utility model most preferred embodiment.
The specific embodiment
Below the specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of winder of the present utility model comprises the spiral seat 10 of Y-shaped.On spiral seat 10, there is a circular hole 12, in circular hole 12, by a bearing 14, a rotating shaft 16 is installed.It is the reel 18 of H font that one cross section is set in rotating shaft 16, and power line (not shown) furls on reel 18.
One position-limited wheel 20 and wind spring 22 are also set in rotating shaft 16.Position-limited wheel 20 is fixed on reel 18 by modes such as screw or clampings, and one end of wind spring 22 is fixed on spiral seat 10, and the other end is fixed on reel 18.
On the periphery wall of position-limited wheel 20, be evenly provided with several wedge shape lug bosses 24(as the structure of ratchet), it is a common structure, each lug boss 24 comprises one domatic (not shown) and a facade (not shown), whole lug bosses 24 domatic towards unanimously.The positive stop strip 26 of a strip, arranges a hole of running through 28 in the middle of it, by a screw through this hole 28, be fixed on spiral seat 10, forms rotating lever construction.One free end of positive stop strip 26 is resisted against on lug boss 24, and the other end arranges a columniform erection column 30, and a stage clip 32 is set on erection column 30, and the other end of stage clip 32 is resisted against on spiral seat 10.
Like this, at the free end of the effect lower limit bar 26 of stage clip 32, be tightly resisted against on the facade of lug boss 24, stop wind spring 22 to drive position-limited wheels 20 rotations.When thereby user pulls power line to drive reel 18 and position-limited wheel 20 to rotate, the free end of positive stop strip 26, along the domatic movement of lug boss 24, does not hinder the rotation of reel 18 and position-limited wheel 20.When pressing while furling button (not shown), press the other end of positive stop strip 26, make positive stop strip 26 leave lug boss 24, thereby do not hinder the rotation of reel 18 and position-limited wheel 20, the elastic force of wind spring 22 is had an effect, drive reel 18 and position-limited wheel 20 to rotate, furl power line.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
