Abstract
The utility model relates to a kind of sunshading curtain winding shock absorber, it comprises power-transfer clutch, damper, output shaft, support sleeve and rotating shaft, described output shaft one end connects in described damper, the other end connects described support sleeve, described damper connects described power-transfer clutch further, and described power-transfer clutch and support sleeve outside face have on protrusion muscle, and described rotating shaft inside face has groove, described protrusion muscle snaps onto in the groove of described rotating shaft, and described clutch seizure can drive described damper to rotate.Can reduce sunshading curtain winding speed under the effect of damper during sunshading curtain winding shock absorber retracting of the present utility model, overcome the noise because pull bar shock shell during retracting produces, the outward appearance of protection sun screen, better meets the demand of client.
Description
Technical field
The utility model relates to sun screen field, is more particularly to a kind of sunshading curtain winding shock absorber.
Background technology
At present, although the quick retracting action of existing sun screen can not affect the sunshade function of cord, but because existing retracting does not have shock absorber, because torsion spring drives the effect cord of pre-police strength retracting speed very fast, cause pull bar and shell to produce clash into and send larger noise, also can cause the vibrations of parts, therefore this sun screen is intricacies poor, there is larger defect simultaneously.
In order to solve the problems of the technologies described above, the utility model proposes a kind of sunshading curtain winding shock absorber, this device adopts one-way buffer device, does not produce buffering when sun screen launches; Under the effect of damper, reduce sunshading curtain winding speed during retracting, overcome the noise because pull bar shock shell during retracting produces, the outward appearance of protection sun screen, better meets the demand of client.
Utility model content
Technical problem to be solved in the utility model is to provide one can reduce sunshading curtain winding speed when furling; overcome the noise because pull bar shock shell during retracting produces; the outward appearance of protection sun screen, better meets the sunshading curtain winding shock absorber of customer demand.
The technical solution of the utility model is: a kind of sunshading curtain winding shock absorber, it is characterized in that, comprise power-transfer clutch, damper, output shaft, support sleeve and rotating shaft, described output shaft one end is connected in described damper, the other end connects described support sleeve, described damper connects described power-transfer clutch further, the outside face of described power-transfer clutch and support sleeve all has protrusion muscle, described rotating shaft inside face has groove, described protrusion muscle snaps onto in the groove of described rotating shaft, and described clutch seizure can drive described damper work to produce damping.
In sum, the beneficial effects of the utility model are: this novel sunshading curtain winding shock absorber adopts one-way buffer device, does not produce buffering when sun screen launches; Under the effect of damper, reduce sunshading curtain winding speed during retracting, overcome the noise because pull bar shock shell during retracting produces, the outward appearance of protection sun screen, better meets the demand of client.
The utility model is described in more detail below by embodiment.
Accompanying drawing explanation
Fig. 1 is the structural representation of sunshading curtain winding shock absorber of the present utility model;
Fig. 2 is the structural representation of another model of sunshading curtain winding shock absorber of the present utility model;
The sunshading curtain winding shock absorber that Fig. 3 is is arranged on the structural representation on sun screen.
Detailed description of the invention
The utility model is further described with embodiment below in conjunction with accompanying drawing 1-3.But protection domain of the present utility model is not limited to this.
With reference to accompanying drawing 1-3, illustrated therein is the concrete structure of sunshading curtain winding shock absorber all parts of the present utility model, as illustrated in fig. 1 and 2, load rotating shaft 3 after power-transfer clutch 1, damper 4, output shaft 5 and support sleeve 2 and assembling, the protrusion muscle of power-transfer clutch 1 and support sleeve 2 snaps in the groove of rotating shaft 3 inside.When sun screen cord launches, rotating shaft 3 is rotated and is with dynamic clutch 1, support sleeve 2, damper 4, output shaft 5 to rotate, and now shock absorber is inoperative, does not produce buffering; When sun screen is in the torsion spring actuating device predetermincd tension effect last volume time receiving, clutch seizure, the work of band fluctuation dampers which produces damping, slows down the retracting speed of sun screen, overcome the pull bar produced due to retracting excessive velocities and clash into shell, lower the velocity of rotation of rotating shaft 3 until retracting is to reference position.
The working process of sunshading curtain winding shock absorber of the present utility model is as follows: when pulling down fixed handle 6 with hand, and pull pull bar 7 sunshade cord 11 to launch from shell 9, power-transfer clutch 1 is in idling conditions, and damper 4 does not now rotate, and sun screen launches smooth and easy; When sun screen is in the torsion spring actuating device 10 predetermincd tension effect last volume time receiving, sunshading curtain winding shock absorber 8 is started working, and namely power-transfer clutch 1 wherein starts occlusion, and band fluctuation dampers which 4 works and produces damping, slows down the retracting speed of sun screen.
Sunshading curtain winding shock absorber purposes of the present utility model and radical function: this mechanism is sunshading curtain winding auxiliary device, lower sunshading curtain winding hourly velocity, reduce and clash into produced noise by sunshading curtain winding;
Sunshading curtain winding shock absorber of the present utility model, adopts one-way buffer device, does not produce buffering when sun screen launches; Under the effect of damper, reduce sunshading curtain winding speed during retracting, overcome the noise because pull bar shock shell during retracting produces, the outward appearance of protection sun screen, better meets the demand of client.
Sunshading curtain winding shock absorber of the present utility model is not limited to the connection structure in above-described embodiment, can carry out multiple modification, in a word, all falls in scope of the present utility model not departing from all improvement in the utility model scope.
