Abstract
The utility model relates to an automatic roll-up type automobile pull rope device comprising a pull rope with hooks on two ends. The pull rope roll-up device is disposed on the rotating shaft in the housing, and two ends of the pull rope extend out of the housing. The housing is provided with a spiral spring and a rotating shaft, which are cooperated with each other to form an automatic roll-up mechanism. By using the spiral spring to roll the pull rope back automatically, the pull rope can keep the elastic stretching status, and can be stretched or drew back without being trailed on the ground according to the changing distance between two cars, thereby the traction is more safe. When the device is not in use, the pull rope can be automatically rolled up in the housing like the tape measure structure. The utility model has advantages of simple structure, tight size, small occupied area, and convenient use.
Description
Technical field: the utility model relates to the rope hauling device of the dilatory traction of a kind of self-propelled vehicle usefulness.
Background technology: general vehicle traction stay cord all is to be provided with hook at two ends, utilize during use to link up with to tangle tractor truck respectively and be pulled car, but the distance owing to two cars can't be stablized maintenance in travelling, and stay cord is easy to tenesmus and mops floor.And common stay cord twines into one easily when carrying with car, very mixed and disorderly, and it is many to take up room, and brings inconvenience to use.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of can the tenesmus to mop floor, the automatic easily coiling type automobile rope hauling device of rolling.
The utility model comprises that two ends have the stay cord of hook, and this stay cord rolling places in the rotating shaft of housing, and two ends of stay cord expose to housing, also is provided with wind spring and rotating shaft in the housing and cooperates, and constitutes automatic rewinding mechanism.
The utility model utilizes wind spring automatic rewinding stay cord, and stay cord keeps the elastic tightening state during use, and two spacings also can elongate thereupon or shrink when changing automatically, and can not drop mops floor, and draws safer.And when not using, stay cord can furl in housing automatically, and similar tape measure structure is simple in structure, and volume compact carries and occupies little space, and uses easily.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure scheme drawing of embodiment;
Fig. 2 is the birds-eye view of Fig. 1.
Embodiment: as shown in the figure, two ends of stay cord 2 have hook 4, and these stay cord 2 rollings place in the rotating shaft 3 of housing 1, and two ends of stay cord 2 expose to housing 1, also are provided with wind spring 5 in the housing 1 and rotating shaft 3 cooperates, and constitute automatic rewinding mechanism.General wind spring 5 has two, is separately positioned on the biend place of housing 1, backrush great efforts and more even.2 of stay cords are flat belt-like, and it is compacter to furl the back volume.
During use, two hooks 4 are hung on the two cars, the distraction procedure of travelling medium pulling rope 2 elasticity backrush always tension, can not drop because of the variation of two spacings mops floor.When not using wind spring 5 drive rotating shafts 3 with stay cord 2 automatic rewindings in housing 1, similar tape measure, very convenient.
