Description
Technical field
The utility model relates to a kind of pet tractor of rope automatically retractable.
Background technology
Existing pet tractor comprises shell, with integrally formed lever, the rotating disk of shell, be coiled in rope, wind spring and cord-lock on the rotating disk, rope can freely be stretched by pet, when pet is motionless, reset by wind spring, rope can shrink in the shell body automatically, when need were fixed one section rope lengths, it was just passable to press cord-lock.Existing cord-lock structure is the wheel construction of pressing of similar ball pen, this structure cooperates the realization cord-lock to unclamp rope or locking rope by gear, block through using a period of time to find easily to misplace between the gear, thereby make cord-lock lose effect, cause pet tractor not use.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of pet tractor simple in structure, long-lived.
The purpose of this utility model is achieved in that
A kind of pet tractor, comprise shell, with integrally formed lever, the rotating disk of shell, be coiled in rope, wind spring and cord-lock on the rotating disk, the outer wall periphery of rotating disk evenly is interval with spacing shelves, and described cord-lock comprises button, back-moving spring, push rod, securing rod, clamping block and connecting rod;
Securing rod the inner is provided with the locking pin, the securing rod middle part is provided with strip hole, clamping block comprises face and pin, facial surface is dug a loop-shaped and is heart-shaped chute, the strip hole that pin passes securing rod is connected with housing, the facial strip hole top that is located in, the connecting rod outer end is installed in the securing rod outer end, connecting rod the inner is positioned at the facial chute of clamping block, push rod is inner to be connected and interlock with securing rod, thereby push rod and securing rod partially overlap and make push rod push down connecting rod, prevent the connecting rod bar that goes out of lock, back-moving spring the inner is set on the coincidence part of push rod and securing rod and is connected with them, together inserts in the button then, the outer end of back-moving spring leans in button body and is attached thereto, and the button external end head stretches out shell;
Described button is stressed and moves in shell, by the back-moving spring extruding push rod and securing rod are moved towards rotating disk, because clamping block is motionless, move along chute by the chute guiding the inner of connecting rod, withstood by rotating disk when the locking pin of described securing rod the inner inserts between two spacing shelves of rotating disk periphery and stop to move, this moment, the chute bottom that is heart-shaped was caught in the inner of connecting rod;
When described button is stressed in shell body when mobile once more, connecting rod is inner to be continued to move and break away from the chute bottom and spur securing rod away from rotating disk by action of reset spring along chute.
Said structure also can be done further perfect:
Described push rod is provided with the shell fragment of a suspended wall, and when push rod overlapped with securing rod, shell fragment suppressed connecting rod.
Three corners of described heart-shaped chute are equipped with ladder, and limiting connecting rod the inner by three ladders can only move in chute along a direction.
The utility model structural design advantages of simple, operation is light, convenient, good hand touch, rope is capable of expansion and contraction, is a kind of desirable pet tractor.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In conjunction with Fig. 1 to Fig. 6, a kind of pet tractor, comprise shell 1, with integrally formed lever 2, the rotating disk 3 of shell, be coiled in rope (not shown), wind spring 5 and cord-lock 6 on the rotating disk, shell 1 by about two housings realize that by screw and fixed leg dismounting is connected, the outer wall periphery of rotating disk 3 evenly is interval with spacing grade 7.
Described cord-lock 6 comprises button 60, back-moving spring 61, push rod 62, securing rod 63, clamping block 64 and connecting rod 65, and securing rod 63 the inners are provided with locking pin 630, and securing rod 63 middle parts are provided with strip hole 631.Clamping block 64 comprises face 640 and pin 641, and facial 640 surfaces are dug a diagram shape and are heart-shaped chute 642, and three corners of heart-shaped chute 642 are equipped with ladder 643,644,645.The strip hole 631 that pin 641 passes securing rod is connected with housing 1, and facial 640 are located in strip hole 631 tops.Connecting rod 65 outer ends are installed in securing rod 63 outer ends, and connecting rod 65 the inners are positioned at the facial chute 642 of clamping block, and limiting connecting rod the inner by three ladders 643,644,645 can only move in chute along a direction, can not reversely move.Push rod 62 is inner to be connected and interlock with securing rod 63, and push rod 62 and securing rod 63 partially overlap, and push rod 62 is provided with the shell fragment 620 of a suspended wall, when push rod overlaps with securing rod, prevents the connecting rod bar that goes out of lock thereby shell fragment 620 suppresses connecting rod 65.Back-moving spring 61 the inners are set on the coincidence part of push rod and securing rod and are connected with them, together insert then in the button 60, and the outer end of back-moving spring 61 leans in button 60 bodies and is attached thereto, and button 60 external end heads stretch out shell 1.
