Abstract
The utility model relates to a non-return sunshade curtain, in particular to the non-return sunshade curtain with a ratchet wheel and ratchet structure. The non-return sunshade curtain comprises a ratchet wheel, pawl, a torsional spring, a driving wheel, a first end base and a sleeve, wherein a protruded ratchet wheel shaft is arranged on the first end base, the root portion of the ratchet wheel shaft is in sleeved connection with the ratchet wheel, the matched pawl is arranged on the ratchet wheel, the pawl is movably connected onto the first end base through a rotating shaft, the end portion of the ratchet wheel shaft is fixedly connected with one end of the torsional spring, the other end of the torsional spring is coaxially fixed with the driving wheel, a sleeve pipe is further sleeved outside the torsional spring, the sleeve is sleeved outside the sleeve pipe, one end of the sleeve is coaxially and fixedly connected with the ratchet wheel, and the driving wheel is fixed in the sleeve. The non-return sunshade curtain can conduct automatic return prevention on a sunshade curtain and enables the sunshade curtain to keep at a certain height, the sleeve pipe sleeved outside the torsional spring enables the torsional spring to keep the shape in the process of torsion, and enables torsion to become more stable, when a user uses the non-return sunshade curtain, force application of the user is more stable, the sleeve pipe can also ensure that in the process of torsion of the torsional spring, the inner surface of the sleeve can not be damaged by the torsional spring, and therefore the service life of a product is prolonged.
Description
[technical field]
The utility model relates to the non-return abat vent, is specifically related to have the non-return abat vent of ratchet ratchet structure.
[background technology]
Domestic patent 94248504 discloses a kind of self rolling curtain, be provided with the click that non-return is used in this curtain, ratchet is provided with torsion spring and is used for from volume, be provided with the connected set bar of similar torsion spring mandrel in the torsion spring, the purpose that the connected set bar is set is to prevent that torsion spring from unnecessary deformation taking place when reversing diametrically, but mandrel will pass through recessing, mill technologies such as flat, also to assemble operations such as several jump rings, technology is cumbersome, and deformation also can cause with roller and produce friction, reduce efficient and the stability of curtain folding and unfolding simultaneously.
[summary of the invention]
In order to remedy the above-mentioned deficiency of prior art, the utility model provides the abat vent of the non-return with ratchet ratchet structure.
For achieving the above object, design a kind of non-return abat vent, comprise ratchet, ratchet, torsion spring, driving wheel, first end seat and the sleeve, it is characterized in that being provided with at the first end seat ratchet shaft of protrusion, ratchet shaft root socket ratchet, the ratchet that matches is set on the ratchet, ratchet is movably connected on the first end seat by rotating shaft, fixedly connected torsion spring one end in ratchet shaft end, the torsion spring other end is coaxial fixing with driving wheel, and torsion spring also is with sleeve pipe outward, and sleeve pipe is with sleeve outward, one end of sleeve is fixedlyed connected with coaxial ratchet, and described driving wheel is fixed in the sleeve.
This non-return abat vent also has following optimizing structure:
Described ratchet shaft axially is the stairstepping of three-layer type, ratchet shaft root socket ratchet, sleeve pipe and spring successively to each layer ladder of end.
The non-return abat vent also comprises rotor and the second end seat, and the described sleeve other end is fixedlyed connected with rotating shaft with rotor, on the described second end seat armature spindle is set, and rotor is enclosed within on the armature spindle.
The non-return abat vent also comprises cover body, and described cover body is fixedly connected on the first end seat and the second end seat.
Described ratchet is formed by calvus with for the back-moving spring of the calvus that resets.
Described internal surface of sleeve pipe is provided with some axial flanges, the wheel side face of described driving wheel is provided with some blocks, described block all is connected in twos between the flange, and described rotor surface is provided with some blocks, and described block all is connected in twos between the flange.
Described sleeve surface arranges abat vent.
Need not to assemble mandrel in the torsion spring of non-return abat vent of the present utility model, cost reduces greatly, and can carry out automatic braking to abat vent, thereby make abat vent can remain on certain height, sheathed sleeve pipe can make torsion spring keep its form when reversing outside torsion spring, make to reverse and become more stable, thereby user's application of force in use is also more steady, another effect of sleeve pipe is to guarantee that torsion spring can not damage the inner surface of sleeve when twisting, thus the application life of the product that increases.

[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, by reference to the accompanying drawings the utility model is further elaborated.Production equipment among the application all is the common equipment of this area, should be appreciated that specific embodiment described herein only in order to explaining the utility model, and is not used in restriction the utility model.
The non-return abat vent, comprise ratchet, ratchet, torsion spring, driving wheel, the first end seat, the second end seat, rotor, sleeve and cover body, the first end seat is provided with the ratchet shaft of protrusion, ratchet shaft axially is the stairstepping of three-layer type, socket ratchet on the ladder of ratchet shaft root, the ratchet that matches is set on the ratchet, ratchet is movably connected on the first end seat by rotating shaft, ratchet is formed by calvus with for the back-moving spring of the calvus that resets, fixedly connected torsion spring one end on the ladder of ratchet shaft end, the torsion spring other end is coaxial fixing with driving wheel, torsion spring also is with sleeve pipe outward, internal surface of sleeve pipe is provided with some axial flanges, and an end of sleeve pipe is socketed on the middle ladder of ratchet shaft, and sleeve pipe is with sleeve outward, one end of sleeve is fixedlyed connected with coaxial ratchet, driving wheel is fixed in the sleeve, and the wheel side face of described driving wheel is provided with some blocks, and described block all is connected in twos between the flange.The other end is fixedlyed connected with rotating shaft with rotor, and described rotor surface is provided with some blocks, and described block all is connected in twos between the flange.On the described second end seat armature spindle is set, rotor is enclosed within on the armature spindle, and sleeve surface arranges abat vent, fixedlys connected for the cover body of shade abat vent on the first end seat and the second end seat.
