Abstract

A pet retractor comprises a casing, a rotating disc and a retractable rope wound around the rotating disc, wherein a rotating disc rewinding body is arranged between the casing and the rotating disc;radial ratchets are formed at the circumference of the rotating disc; and at the same time, a locking mechanism for limiting the rotating disc is mounted on the casing. The pet retractor is characterized in that the locking mechanism adopts a pushing button; pawls meshed with the ratchets are arranged on the inner surface of the head part of the pushing button; a limited post and a limit slot arearranged between the pushing button and the casing; a spring which can keep the tail part of the pushing button always tending to be exposed to the casing is arranged between the tail part of the pushing button and the casing; and when the limited post is positioned in the limit slot, the spring can be compressed so as to make the pawls drift off the ratchets. By adopting the method of the pushingbutton movement, the pawls at the head part of the pushing button can be meshed with the ratchets on the rotating disc, so that the stopping of the rotating disc can be realized so as to achieve thepurpose of restricting the retractable rope from overhanging; and with the assistance of the spring, the pushing method has the advantages of flexible brake and good feeling, thereby providing a pet host with a more practical retractor.

Description

A kind of pet tractor

Technical field

The utility model relates to a kind of pet tractor.

Background technology

In order to prevent that pet from wandering away, owners usually are pet configuration tractor.At present, commercially available pet tractor has been diversified structure, it generally comprises housing, be arranged on rotating rotating disk in the housing and be wrapped in pull rope on the rotating disk, be provided with the backrush body between housing and the rotating disk, this backrush body adopts the wind spring structure mostly, locking mechanism is installed on housing simultaneously, this locking mechanism can adopt forms such as button, the outer end of button has the trend that exposes to housing all the time in the effect of spring, and spacing grade of being ratchet shape on inner and the rotating disk matches, as required rotating disk is locked.

And present being seen button is to arrange with the radial direction of rotating disk mostly, as Chinese patent Granted publication number for disclosing of CN201075936Y above-mentioned so a kind of structure, when pressing the button, the ratchet engagement on the ratchet of button the inner trend and the rotating disk; When button was upspring, ratchet broke away from the ratchet on the rotating disk, realized that pull rope has the stretching, extension of pulling but purpose that can the resilience contraction with this.

The utility model content

Technical problem to be solved in the utility model be a kind of novel structure is provided at above-mentioned prior art present situation and have braking flexibly, the pet tractor of good hand touch.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this pet tractor includes housing with handles, be arranged on rotating disk and the pull rope that is wrapped on the rotating disk in the housing rotationally, be provided with rotating disk backrush body between described housing and the rotating disk, the circumferential edge of described rotating disk is provided with radially ratchet, on housing, be equipped with simultaneously rotating disk is carried out spacing locking mechanism, it is characterized in that: described locking mechanism is a push button, has the ratchet that can be meshed on the head inner surface of this push button with described ratchet, be provided with limited post and stopper slot between described push button and the housing, then be provided with between described push button afterbody and the housing and make described push button afterbody expose to the spring of housing trend all the time, and work as described limited post and be positioned under the state of stopper slot, described spring is compressed and makes described ratchet depart from described ratchet.

As preferred version of the present utility model, described reference column can be positioned on the side of push button, and described stopper slot is positioned on the madial wall of housing.

As another kind of preferred version of the present utility model, can also be formed with lead on the described push button sidewall, and on the madial wall of described housing, have and the corresponding gathering sill of this lead, so that assemble convenient.

Compared with prior art, because what the utility model adopted is the mode that push button moves, the head ratchet of push button is meshed with ratchet on the rotating disk, realize the stop of rotating disk and reach the overhanging purpose of restriction pull rope with this, and by means of spring, make this way of propelling, have braking flexibly, the characteristics of good hand touch, thereby provide a kind of practical more tractor for pet owners.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, this pet tractor comprises with handles 11 housing 1, rotating disk 4, be wrapped in the pull rope (not shown) on the rotating disk and rotating disk carried out spacing locking mechanism, wherein, housing 1 is realized removably connecting by the screw and the fixed leg of routine by left and right half housing, the pattern of the both side surface design dog pawl seal of housing, and be inlaid with ornamental diamond 3.Rotating disk 4 and be installed on the central shaft 12 in the housing as the wind spring 5 of backrush body so that rotating disk can rotate along the stretching of pull rope, have rotating trend again, and design has radially ratchet 41 on the two side circumferential edge of rotating disk 4.

Above-mentioned locking mechanism is one to be installed near the push button 2 the handle 11, has the ratchet 21 that can be meshed on the head inner surface of this push button 2 with the ratchet on the above-mentioned rotating disk, the side one design of push button has limited post 22 and lead 23, wherein lead 23 is adjacent to the head of push button, and limited post 22 is provided with the gathering sill 14 and the stopper slot 13 that stretch into for lead, limited post end respectively near the afterbody of push button on the corresponding housing madial wall; Simultaneously then be provided with spring 6 between push button afterbody and housing, an end of this spring is against on the limiting plate 15 of housing, and the other end is enclosed within on the reference column 24 of push button afterbody, makes the push button afterbody have the trend that exposes to housing all the time.

When push button 2 moves to its rear side, and when making limited post 22 be positioned at stopper slot 13, above-mentioned spring 6 is compressed and makes ratchet 21 depart from ratchet 41 on the rotating disk, see also Fig. 2, at this moment, the ratchet 41 on the rotating disk is not subjected to any stopping, pet advances and pulls pull rope in the process, pull rope can optionally be extracted out from rotating disk 4, and wind spring 5 compresses thereupon; In case and the pull rope pine is when overstating, then under the effect of wind spring, the pull rope automatic drawing back is to rotating disk; In a word, under this state, pull rope is freely to stretch with the walking of pet or to bounce back.

In above-mentioned free drawing process, if need pet to halt, then as long as push earlier the afterbody of push button 2 downwards, make limited post leave stopper slot on the inner walls, and promote push button again, it is moved to head side, at this moment, push button 2 is under the effect of spring 8, and the push button afterbody moves on hull outside, also conflicts at ratchet in the ratchet reach back of head, as shown in Figure 5, continue to rotate counterclockwise with the prevention rotating disk,, reach the restriction pull rope then and pull the purpose that stretches.
