[specific embodiment]

The utility model is described in further detail below in conjunction with specific embodiment.

See also Fig. 3, trailer rope of the present utility model comprises a constrictor 10, the rope 30 and the energy disperser 80 of first, second hauling hook 20,21, flat pattern.Energy disperser 80 is connected between the constrictor 10 and first hauling hook 20, and the two ends of rope 30 are connected with second hauling hook 21 and constrictor 10 respectively, and this rope 30 is collapsible in constrictor 10.

Constrictor 10 comprises shell 40, main shaft 50, shim liner 60 (see figure 9)s and cup spring 70.Main shaft 50 is installed on the shell 40, and it is connected with rope 30, and free to rotate.The shell 40 of constrictor 10 is fixed in the outer end of cup spring 70, and the inner is connected in the main shaft 50 of constrictor 10.

See also Fig. 4, Fig. 5 and Fig. 6, shell 40 have two parallel side walls 41, and this two side 41 has corresponding through

hole

42,43 respectively, is used to install main shaft 50.

See also Fig. 7 and Fig. 8, main shaft 50 comprises cylinder-shaped body part 51, is positioned at the

circular fin

52,53 at two ends.In addition, be used to hold the trapezoidal hole 55 of shim liner 60 in the 51 horizontal formation one of cylinder-shaped body part.The cross-sectional area of

circular fin

52,53 is greater than the cross-sectional area of the

through hole

42,43 of shell 40, and the cross-sectional area of shank 51 is also greater than the cross-sectional area of through

hole

42,43.

See also Fig. 9, the shape of the trapezoidal hole 55 on the shape of shim liner 60 and the main shaft 50 is corresponding.

See also Figure 10 and Figure 11, first, second hauling hook 20,21 all has a portable bar 201,211, presses portable bar 201,211 toward in and can expose a breach, is used for the convenient trailer rope of hanging.Other first hauling hook 20 also comprises an extension rod 202, and these extension rod 202 ends have a flange 203.

See also Fig. 3, Fig. 6 and Figure 12, energy disperser 80 comprises spring 81 and spring overcoat 82.This spring overcoat 82 is welded in shell 40, has a step 83 in it.During assembling, the spring 81 of energy disperser 80 is loaded on spring overcoat 82, and one end against step 83, the extension rod 202 of first hauling hook 20 passes spring 81, by beaing or additive method makes the end of extension rod 202 form flange 203, the other end that makes spring 81 is against flange 203, when spurring first hauling hook 20 at last, spring 81 is collapsible between the flange 203 of the step 83 of spring overcoat 82 and extension rod 202, thereby can reach the effect of buffering.

See also Fig. 3 to Figure 12, when assembling this trailer rope, at first main shaft 50 is installed on shell 40, and make its two ends pass the through

hole

42,43 of shell 40, by beaing or additive method makes

fin

52,53 be formed at the two ends of main shaft 50 respectively, the two side 41 of shell 40 is sandwiched between fin 52 and the shank 51 respectively, between fin 53 and the shank 51, make main shaft 50 be installed on the shell 40, and free to rotate.One end of the rope 30 of flat pattern is wrapped shim liner 60, with line that its seam is tight, big opening one end of rope 30 from trapezoidal hole 55 passed and pass from little opening part, pad 60 is wedged the trapezoidal hole 55 of main shafts 50 then, the other end of rope 30 is connected second hauling hook 21, the shell 40 of constrictor 10 is fixed in the outer end of cup spring 70, and the inner is connected in the main shaft 50 of constrictor 10.Because the effect of cup spring 70, rope 30 shrinks automatically in main shaft 50.Spring overcoat 82 is welded in shell 40, spring 81 is loaded on spring overcoat 82, and one end against the step 83 of spring overcoat 82, the extension rod 202 of first hauling hook 20 passes spring 81 and spring overcoat 82, by beaing or additive method makes the terminal flanges 203 that form of extension rod 202, the other end that makes spring 81 is against flange 203 at last.

During use, press the portable bar 201 of first hauling hook 20, first hauling hook 20 is hooked vehicle, then rope 30 is pulled out from constrictor 10, main shaft 50 rotates, and drives cup spring 70, makes cup spring 70 shrink.Second hauling hook 21 hooks another vehicle, when vehicle connect, first hauling hook 20 was stressed, its flange 203 extrusion springs 81, thereby improve the cushion characteristic of trailer rope, prevent that rope 30 phenomenon of ruptures that automobile causes because of impulse force is excessive from taking place when starting or acceleration phase.When not using, rope 30 can be shunk in main shaft 50 by the effect of cup spring 70.

Because trailer rope of the present utility model can shrink rope 30 in main shaft 50 automatically by cup spring 70, and is easy to carry, and the main shaft 50 of constrictor 10 is connected firmly difficult disengaging during use with rope 30.In addition,, can improve the cushion characteristic of trailer rope, prevent that rope 30 phenomenon of ruptures that automobile causes because of impulse force is excessive from taking place when starting or acceleration phase by the effect of energy disperser 80.

Although the utility model is to describe with reference to specific embodiment, this description and not meaning that is construed as limiting the utility model.With reference to description of the present utility model, other distortion of the disclosed embodiments all can be expected for those skilled in the art.Therefore, such distortion can not break away from affiliated claim restricted portion and spirit.
