Therefore, to increase the anti-reversion function of the awning, the winding is stable, the winding is neat, the existing anti-reversion structure generally occupies a large size, more parts are needed, the cost is high, and the stability is general.
Disclosure of utility model
The utility model aims to solve the problems and provide an anti-reversion structure of a sunshade, which can prevent reversion when unreeling and irregular reeling of the sunshade.
The technical scheme adopted by the utility model is as follows:
The utility model provides a awning anti-reversion structure, its characterized in that includes the reelpipe, the reelpipe is cavity, the reelpipe is equipped with the binding off groove outward, the binding off inslot is fixed to be set up the puggaree, set up the stopcock in the reelpipe, set up the pivot in the stopcock, the pivot is connected to actuating mechanism, be connected through unidirectional rotating mechanism between pivot and the stopcock, when actuating mechanism drive pivot rotates and rolls up the puggaree, unidirectional rotating mechanism locks.
Further, the unidirectional rotating mechanism is a unidirectional needle bearing, an inner ring of the unidirectional needle bearing is matched with the shaft pin, and an outer ring of the unidirectional needle bearing is matched with the winding pipe.
Further, the unidirectional rotation mechanism is a ratchet wheel, the ratchet wheel is arranged on the shaft pin, the outer ring is fixed with the tube coil, and the pawl is arranged on the shaft pin and positioned on one side of the ratchet wheel teeth.
Further, snap spring grooves are formed in the shaft pin and located at two ends of the pipe plug, snap springs are arranged in the snap spring grooves, the pipe plug is limited by the outer snap springs, and the unidirectional rotation mechanism is limited by the inner snap springs.
Further, the coiled pipe is a section bar, a hollow pipe is formed in the middle of the coiled pipe, the pipe plug is tightly matched between the hollow pipe and the coiled pipe, and the unidirectional rotating mechanism is tightly matched in the hollow pipe.
Further, the cross section of the hollow tube is regular polygon, the outer surface of the unidirectional rotation mechanism is also regular polygon corresponding to the regular polygon, and the unidirectional rotation mechanism is installed in cooperation with the hollow tube.
The beneficial effects of the utility model are as follows:
(1) Only can rotate in the unreeling direction during unreeling, so that the occurrence of reversal is avoided;
(2) The unidirectional rotating part is arranged in the coiled pipe, and does not occupy space.

FIG. 2 is a schematic view of the internal structure of the coil of the present utility model;
Fig. 3 is an expanded view of the inside of the coil of the present utility model.
The reference numerals in the drawings are respectively:
1. a coiled pipe; secondly, sun-shading cloth;
3. A closing-in groove; fourth, the pipe plug;
5. A shaft pin; sixthly, a hollow tube;
7. a clamp spring groove; eighthly, clamping springs;

Description of the embodiments
The following describes in detail the embodiments of the anti-reverse structure of the awning according to the present utility model with reference to the accompanying drawings.
Referring to fig. 1, when the awning cloth 2 on the awning roller tube 1 is pulled out, unidirectional output is realized through a unidirectional rotation mechanism, so that the possibility of reversion is overcome.
The winding pipe 1 of the awning is hollow, a closing-in groove 3 is arranged outside the winding pipe 1, and the sunshade cloth 2 is fixedly arranged in the closing-in groove 3. A pipe plug 4 is arranged in the winding pipe 1, a shaft pin 5 is arranged in the pipe plug 4, the shaft pin 5 is connected to a driving mechanism, the shaft pin 5 is connected with the pipe plug 4 through a unidirectional rotation mechanism, and when the driving mechanism drives the shaft pin 5 to rotate to wind the sun-shading cloth 2, the unidirectional rotation mechanism is locked.
Referring to fig. 2 and 3, the coiled pipe 1 of the patent is a section bar, and a hollow pipe 6 is formed in the middle. The pipe plug 4 is tightly matched between the hollow pipe 6 and the coiled pipe 1, and the unidirectional rotation mechanism is tightly matched in the hollow pipe 6. The two ends of the shaft pin 5, which are positioned on the pipe plug 4, are provided with snap spring grooves 7, snap springs 8 are arranged in the snap spring grooves 7, the pipe plug 4 is limited by the outer snap springs 8, and the unidirectional rotation mechanism is limited by the inner snap springs 8.
The unidirectional rotating mechanism can be a unidirectional needle bearing 9, and the outer ring of the bearing is matched and arranged in the hollow tube 6. The hollow tube 6 in the figure is polygonal, and the outer ring of the corresponding unidirectional needle bearing 9 is also polygonal, so that the degree of freedom in the rotation direction is limited after the hollow tube and the outer ring are matched.
Instead of the unidirectional needle bearing 9, a single rotation mechanism such as a ratchet wheel can be used, when the ratchet wheel is used, the ratchet wheel is installed on the shaft pin 5, the outer ring is fixed with the pipe plug 4, and the pawl is arranged on the shaft pin 5 and positioned on one side of the ratchet wheel teeth.
When the sun-shading cloth 2 on the winding pipe 1 needs to be unreeled, the end part of the sun-shading cloth 2 is pulled to be outwards extended, and at the moment, the sun-shading cloth 2 can only be outwards pulled out due to the action of the unidirectional rotating mechanism, so that the phenomenon of reversion cannot occur.
The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
