Description

Single button line wheel switch dog leash

Technical field

The utility model belongs to the dog leash class, specifically is a kind of single button line wheel switch dog leash.

Background technology

Along with the people dog that keeps a pet is more and more, the market of dog leash is also increasing, and the switch that dog leash inner control line wheel rotates is the key device of dog leash, directly influences the serviceability of dog leash; Existing dog leash switch generally is made up of two buttons, and this is not easily concerning the user, and influential to the monnolithic case of dog leash, is not very attractive in appearance, and two buttons are also cumbersome when assembling.

Summary of the invention

The purpose of this utility model is the deficiency at present technology, provide a kind of more reasonable structure, assembling faster, use more conveniently, and don't the single button line that influence outward appearance is taken turns the switch dog leash.

The technical solution of the utility model is as follows:

A kind of single button line wheel switch dog leash, comprise housing, lid, the wired wheel in the housing, it is characterized in that: housing is provided with shift knob, switch spring is housed in the shift knob, the borehole jack of shift knob is gone on the cylinder of housing, and an end of switch spring is fixed in the shift knob, and the other end then is against on the cylinder of housing, shift knob has shell fragment, locating piece is arranged on the housing, and locating piece has two inclined-planes and a locating slot, and shell fragment cooperates with locating piece near locating piece.

Shift knob of the present utility model is pressed on earth in housing, in the process that shift knob is pressed, shell fragment on the shift knob slides synchronously along the locating piece on the housing, and the shell fragment on the shift knob is close on the locating piece, after decontroling shift knob, shift knob is under the elastic force effect of switch spring, toward resilience, at this moment during the shell fragment on the shift knob slides into locating slot on the locating piece along the locating piece ramp, the position of shift knob in housing is locked, thereby the wheel of the line in the locking dog leash has so just been finished the function that lock-in line is taken turns; Under lock-out state, shift knob is once more down by on earth, in the process that shift knob is pressed, shell fragment on the shift knob slides into the side on the locating piece along another inclined-plane on the locating piece, after decontroling shift knob, shift knob is under the elastic force effect of switch spring, toward resilience, at this moment the shell fragment on the shift knob slides along the locating piece upper side, shift knob is got back to original unlocked state, and the line wheel in shift knob and the dog leash breaks away from, and the line wheel just can freely rotate, so just finished unlocking function, needed in the course of work to work repeatedly by switch spring.

When the utility model uses, pressing shift knob decontrols the back on earth, just can finish the locking of dog leash, pressing shift knob once more decontrols the back on earth, just can finish unblanking of dog leash, such switching device more convenient operation, more reasonable structure, since easy to assembly, production efficiency also improved greatly.
