Abstract

The utility model belongs to the kind of a dog leash, in particular to a dog-leash line-wheel rotation and braking switch device, comprising a shell body and a cover body, wherein a line wheel is arranged in the shell body. The utility model is characterized in that the shell body is provided with a switch button, a decorative piece and a locking block, and the switch button is sheathed in a corresponding hole of the decorative piece and is arranged on the corresponding position of the shell body and the cover body at the same time. A limiting rod on the switch button is arranged in a sliding groove of the shell body, and a sliding card groove on the decorative piece is buckled on the side wall of the shell body. The column body of the shell body is sheathed in the corresponding limiting hole of the locking block, and a switch spring is arranged in the locking block. One end of the switch spring is sheathed in the locking block, and the other end is butted on the column body of the shell body. The dog-leash line-wheel rotation and braking switch device is provided with only one switch button. Compared with the existing dog-leash line-wheel switch structure, the dog-leash line-wheel rotation and braking switch device has reasonable structure and beautiful.

Description

Dog leash line wheel rotates and the brake switch device

Technical field

The utility model belongs to the dog leash class, specifically is that a kind of dog leash line wheel rotates and the brake switch device.

Background technology

People are when supporting the slide pet dog, usually use dog leash, line wheel switch in the dog leash is the key device of dog leash, directly influence the serviceability of dog leash, existing dog leash line wheel switch generally is made up of two buttons, needs by next locking press button, also need to promote another button and finish locking process, this is not easily in daily use, and two buttons are often influential to the monnolithic case of dog leash, are not very attractive in appearance.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of more reasonable structure, use is more convenient, profile is more attractive in appearance has only the dog leash line wheel of a button to rotate and the brake switch device.

The technical solution of the utility model is as follows:

A kind of dog leash line wheel rotates and the brake switch device, comprises housing, lid, the wired wheel in the housing, and it is characterized in that: housing is provided with shift knob, cosmetic sheet, lock dog; Shift knob is enclosed within the respective aperture on the cosmetic sheet, is contained in simultaneously on the relevant position of housing and lid, and the gag lever post on the shift knob is contained in the sliding tray of housing, and the slip draw-in groove on the cosmetic sheet is stuck on the housing sidewall; The cylinder of housing is inserted in the corresponding spacing hole of lock dog, and switch spring is arranged in the lock dog, and an end of switch spring is enclosed within the lock dog, and the other end is against on the cylinder of housing.

Shift knob of the present utility model, cosmetic sheet can be carried out set a distance in the relevant position of housing and lid and be slided, press shift knob and drive lock dog down slide into the end after, push away forward again, at this moment shift knob rests on the corresponding sliding tray position of housing, thereby also allow lock dog be positioned at the relevant position of housing, the line that at this moment just can lock in the dog leash is taken turns the function of finishing the lock-in line wheel; After the switching line wheel is pulled on earth backward, lock dog is under the elastic force effect of switch spring, up slide and drive shift knob and up slide simultaneously, at this moment lock dog is got back to original unlocked state, line wheel in lock dog and the dog leash breaks away from, the line wheel just can freely rotate, and has so just finished unlocking function, needs in the course of work to work repeatedly by switch spring.

When the utility model uses, after pressing shift knob and shift knob being shifted onto the end forward, just can finish the locking of dog leash, after shift knob shifted onto the end, lock dog just can automatically reset to original unlocked state, so just finishes the unlocking function of dog leash, and such switching device is rational in infrastructure, simple to operate, easy to use.

Embodiment

As shown in Figure 1, 2, 3, a kind of dog leash line wheel rotates and the brake switch device, comprises housing 1, lid 10, wiredly in the housing 1 takes turns 6, and it is characterized in that: housing 1 is provided with shift knob 3, cosmetic sheet 2, lock dog 4; Shift knob 3 is enclosed within the respective aperture on the cosmetic sheet 2, is contained in simultaneously on the relevant position of housing 1 and lid 10, and the gag lever post 31 on the shift knob 3 is contained in the sliding tray 12 of housing 1, and the slip draw-in groove 22 on the cosmetic sheet 2 is stuck on housing 1 sidewall; The cylinder 13 of housing 1 is inserted in the corresponding spacing hole 41 of lock dog, and switch spring 5 is arranged in the lock dog 4, and an end of switch spring 5 is enclosed within the lock dog, and the other end is against on the cylinder 13 of housing.

Shown in Fig. 2,4, it is the lock-out state of the utility model switching device, shift knob 3 is pressed by after on earth, and being pushed to the end forward, the gag lever post 31 on the shift knob 3 slides along the sliding tray on the housing 1 12, and drive cosmetic sheet 2 is slided synchronously, when at this moment shift knob is positioned at relevant position on the housing 1, and also drive simultaneously on the relevant position that lock dog 4 is positioned at housing 1, lock dog 4 just can lock the interior line of dog leash and take turns 6 like this, and has realized the lock function of dog leash.

Shown in Fig. 2,5, it is the process of unblanking of the utility model switching device, shift knob 3 is back pulled back (cosmetic sheet 2 is slided simultaneously with shift knob 3) on earth, lock dog 4 drives shift knob 3 and up bounces back into reset condition under the elastic force effect of switch spring 5, thereby finishes the unlocking function of the utility model switching device.
