Description

A kind of improvement pet traction device

Technical field

The utility model relates to a kind of improvement pet traction device, and it is connected with the necklace of pet by the traction belt that can take in or discharge.

Background technology

Known improvement pet traction device comprises housing, wheel disc, disc spring, stop bit device and traction belt, described housing is a hollow structure, the middle position that is positioned at housing is provided with fixed leg, wheel disk center is provided with perforate, leave the space between described perforate and the fixed leg, the two ends of disc spring are affixed with the madial wall of fixed leg and wheel disc perforate respectively, traction belt one end is fixed on the radial outside wall of wheel disc, the other end of traction belt extends to hull outside by the band outlet on the housing, the stop bit device is a button, button is located on the housing by a back-moving spring telescopically, one end of button to housing inboard extend and with at least one side of wheel disc along the CONTACT WITH FRICTION setting, when installing, make traction belt be wrapped on the wheel disc fully, disc spring is affixed at normal non-stress state and fixed leg and wheel disc, it is outer and connect a snap close that the other end of traction belt extends to housing, when using, snap close is connected with the necklace of pet, press the button its elastic force that overcomes spring is no longer contacted with wheel disc, wheel disc can discharge or take in traction belt under the situation that is not subjected to external force like this.Its weak point of improvement pet traction device of this kind structure is: owing to be CONTACT WITH FRICTION between an end of button and the wheel disc, for large-scale pet or after using a period of time, cause traction belt normally not take in or to locate because frictional force deficiency or spring force descend, and then endanger public security.

The utility model content

The purpose of this utility model provides a kind of convenient more reliable improvement pet traction device in traction belt location that makes.

The technical scheme that the utility model adopted is such: a kind of improvement pet traction device, comprise housing, wheel disc, disc spring, traction belt and positioner, described housing is a hollow structure, the sidewall of housing is provided with band outlet, the housing middle part is provided with fixed leg, the wheel disc middle part is provided with perforate, nationality be located at rotationally in the housing by the described wheel disc of this perforate and with the coaxial setting of fixed leg, fixedly connected with the madial wall of fixed leg and wheel disc perforate respectively in the two ends of disc spring, one end of traction belt is fixedly arranged on the radial outside wall of wheel disc, the other end of traction belt extends to hull outside by band outlet, described positioner comprises button and back-moving spring, the axial opposite side of the corresponding perforate of described wheel disc is provided with counterbore, described wheel disc axially middle part is provided with dividing plate so that counterbore and perforate axially-spaced, the madial wall of described counterbore along the circumferential direction is provided with ratchet, described ratchet is distributed in the axial outside of counterbore, described button can be located on the housing by back-moving spring with moving axially, button one end be provided with at least two with the suitable dop of ratchet, nationality is taken in by the mutual fastening of this dop and ratchet or disengaging control traction belt, location or release.

Above-mentioned improvement pet traction device, described band outlet cross section are circular arc and extend.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: when needs discharge traction belt, press the button the dop that makes on the button and axially throw off ratchet on the wheel disc, traction belt outwards discharges under the drive of pet like this, when openhanded when driving button, dop fastens with ratchet again under the effect of back-moving spring, and wheel disc can not rotate, and traction belt is positioned; Otherwise after pressing the button, traction belt is not subjected to the pulling force of pet and only is subjected to the screen resilience of disc spring, this moment, traction belt can be received in the housing again by band outlet, and with respect to known friction positioning device, this draw-gear is more safe and reliable to the location of traction belt.

Embodiment

With reference to figure 1, Fig. 2 and Fig. 3, embodiment discloses a kind of improvement pet traction device, it comprises housing 1, wheel disc 2, side panel 3, disc spring 4, traction belt 5, button 6, back-moving spring 7, snap close 8, wherein said housing 1 is to be fastened mutually by left shell 11 and right shell body 12 to form, housing 1 is hollow structure, on the sidewall of housing 1, be provided with one and be the band outlet 13 that circular arc is extended, the middle part of housing 11 is provided with the fixed leg 14 that extends to housing 12, wheel disc 2 is a middle disc structure that is provided with perforate and counterbore, described perforate and counterbore be distributed in the axial both sides of wheel disc 2 and be located at wheel disc 2 axially the dividing plate 21 at middle part keep apart, the madial wall of described counterbore along the circumferential direction is provided with ratchet 22, described ratchet 22 is distributed in the axial outside of counterbore, described button 6 can be located on the right shell body 12 by back-moving spring 7 with moving axially, button 6 one ends be provided with two with the suitable dop 61 of ratchet 22, nationality is circumferentially located wheel disc 2 by dop 61 and the mutual fastening or the disengaging of ratchet 22, and then controls taking in of traction belt 5, location or release.Fixedly connected with the madial wall of fixed leg 14 and wheel disc 2 perforates respectively in the two ends of disc spring 4, side panel 3 is located between wheel disc 2 perforate sides and the left shell 11, the installation that makes things convenient for disc spring 4 is set like this, described wheel disc 2 and fixed leg 14 coaxial settings, the radial outside wall middle part of wheel disc 2 is groove structures that along the circumferential direction extend, one end of traction belt 5 is fixed on the bottom land of groove, when whole traction belt 5 is accommodated in the groove, wheel disc 2 axial two sidewalls can prevent that traction belt 5 is around the unrest or the limit of collapsing, the other end of traction belt 5 extends to outside the housing and with snap close 8 by band outlet 13 and is connected, and snap close 8 is used for the necklace releasable connection with pet.

When using, press the button 6, make button 6 drive dop 61 on it to wheel disc 2 axial medial movement, this process makes dop 61 break away from from ratchet 22, traction belt 5 outside uncoilings under the pet drive like this, and this is the dispose procedure of traction belt 5; Otherwise when traction belt 5 does not stress, press the button 6, under the screen resilience effect of disc spring 4, wheel disc 2 backward rotation are finished the process of taking in of traction belt 5, when release-push 6, under the effect of back-moving spring 7, dop 61 is interlocked with ratchet 22 again, wheel disc 2 is circumferentially located, and traction belt 5 is also corresponding to be positioned.
