Abstract

The utility model relates to a traction rope composed of a box body, a rope winding skeleton, a spring and a button block. The utility model is characterized in that the rope winding skeleton is arranged in the box body, and the traction rope and the spring are arranged on the rope winding skeleton. The button block drives a braking plate through a braking top rod to release the brake of the rope winding skeleton. The pull of the traction rope is larger than that of the spring, the rope winding skeleton rotates, and the rope can be drown out. The pull of the traction rope is smaller than that of the spring, the rope winding skeleton rotates under the action of the spring, the rope can be retraced. The traction rope is used for towing various pets.

Description

Traction cord

The utility model belongs to daily living article, relates to the flexible rope of a kind of energy control.

Existing all can not control flexiblely with rope, it is flexible all can not to control especially for the rope of own pet (as dog, cat) band cover, thus drawing, inconvenience arranged during placement more, and also not attractive in appearance.

In view of above-mentioned deficiency, the purpose of this utility model be invention a kind of can control flexible, shrink the haul line of pull rope automatically.

The purpose of this utility model is achieved in that haul line is to be made of upper cartridge body, lower box body, button piece, braking mandril goring push spring, braking mandril, brake block, clockwork spring, pull rope and wiring skeleton.The axle that the wiring skeleton is installed is arranged in the middle of upper cartridge body and the lower box body, by positioning sleeve, screw the wiring skeleton is installed in the box body, the wiring skeleton can rotate in box body, the clockwork spring of pull rope is housed on the wiring skeleton, and an end of clockwork spring is fixed on the wiring skeleton, and the other end is fixed on the box body, the button piece links to each other with box body by bearing pin, one end of braking mandril contacts with the button piece, and the other end links to each other with keep plate by split pin, and spring is contained in the top of braking mandril.The course of work is such, the knob down piece that press...withes one's finger, and the button piece is depressed braking mandril, and braking mandril drives braking and wantonly puts braking, at this moment if applying external force tow (greater than the pulling force of clockwork spring) can pull out rope along the wiring skeleton, reaches ideal length in box.When finger leaves button, the elastic force of braking mandril goring push spring makes braking mandril drive brake block and pins the wiring skeleton and implement braking; The knob down piece that press...withes one's finger, the button piece is depressed braking mandril, and braking mandril drives plate and wantonly puts braking, at this moment as if no external force tow, the wiring skeleton rotates under the effect of clockwork spring, can be with rope automatically from the wiring skeleton wraparound of box outer, reach ideal length or all wraparounds, the process of finishing the work.

Below in conjunction with description of drawings embodiment of the present utility model:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

In Fig. 1, button piece 1, braking mandril goring push spring 2, braking mandril 3, keep plate 4, clockwork spring 5, pull rope 6.

In Fig. 2, lower box body 7, upper cartridge body 8, positioning sleeve 9, wiring skeleton 10.

Lower box body 7 and upper cartridge body 8, by positioning sleeve 9 and screw wiring skeleton 10 is contained in the box body, pull rope 6 and clockwork spring 5 are housed on the wiring skeleton 10, one end of clockwork spring 5 is fixedly on the wiring skeleton 10, the other end is fixed on the box body, and button piece 1 is contained in the box body by pin, contacts with braking mandril 3 below button piece 1, braking mandril 3 links to each other with keep plate 4 by split pin, and braking mandril goring push spring 2 is contained in the top of braking mandril 3.

Claims (1)
