Description

Pet stretching tractor

Technical Field

The utility model relates to a pet retractor belongs to pet articles for use field.

Background

The pet is good friend of human, accompanies human life, brings much pleasure for people, when carrying the pet out, in order to prevent the pet from going away, control the range of motion of the pet, avoid the pet to hurt other people, need be equipped with the tractor for the pet.

At present, the structural style of the pet tractor sold on the market is various, but generally the pet tractor comprises a shell, a rope disc arranged in the shell and a traction rope coiled on the rope disc, a revolving body used for automatically withdrawing the traction rope is arranged between the shell and the rope disc, the front end of the traction rope is locked on a collar or a strap of a pet through a spring hook, and the range of activity of the pet controlled by the handheld tractor is widened.

The pet retractor of the conventional structure has the following disadvantages: the locking of the braking action and state of the turntable cannot be realized conveniently, the structure is complex, the production cost is high, and the assembly and maintenance difficulty is high.

Disclosure of Invention

In view of this, the utility model provides a pet retractor to solve the problem that pet retractor structure is complicated relatively among the prior art, manufacturing cost is high.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

a telescopic pet tractor comprises a shell, wherein a handle is arranged on the shell, a rotatable turntable is arranged in the shell, a traction rope is wound on the turntable and extends to the outside of the shell through a rope outlet hole formed in the shell;

the rotary table is characterized in that a cylindrical rotating shaft exposed outside the shell is arranged on the shell, a clamping block in linkage fit with the rotating shaft is arranged in the shell, a return spring is arranged on the clamping block, the return spring is respectively abutted against the clamping block and the shell, and the clamping block is matched with a plurality of clamping teeth arranged on the rotary table to circumferentially lock the rotary table.

On the basis of the technical scheme, the utility model discloses can also do following improvement:

furthermore, the rotating shaft is provided with a limiting groove, and the limiting groove is adapted to a limiting column arranged on the shell.

Furthermore, the limiting groove is a plurality of grooves which are uniformly arranged;

spacing post include with casing body coupling's hollow post, spring and spacing ball, the spring with spacing ball sets gradually in the hollow post, hollow post is kept away from the one end of casing with the axis of rotation butt, spacing ball with spacing groove butt.

Furthermore, one end of the traction rope, which is far away from the rope outlet hole, is provided with a hook.

Further, the top of the latch has a tip that extends downward to form an arcuate guide surface.

Furthermore, a rubber retainer is arranged on the rope outlet hole.

The utility model has the advantages that: the utility model discloses a pet tractor simple structure, installation, use, maintenance are just swift in the mean square, and die sinking, low in production cost drive the release and the rolling that the haulage rope can be realized to the fixture block through promoting the axis of rotation, and are easy and simple to handle.

Drawings

Fig. 1 is a schematic view of the structure of the pet retractor of the present invention.

In the drawings, the components represented by the respective reference numerals are listed below:

1. the rope-pulling device comprises a shell, 11, a handle, 12, a rope outlet hole, 2, a rotary disc, 21, a clamping tooth, 3, a pulling rope, 4, a rotating shaft, 5 and a clamping block.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, the telescopic pet retractor comprises a housing 1, wherein a handle 11 is provided on the housing 1, a rotatable turntable 2 is provided in the housing 1, a pulling rope 3 is wound on the turntable 2, and the pulling rope 3 extends to the outside of the housing 1 through a rope outlet 12 provided on the housing 1;

a cylindrical rotating shaft 4 exposed outside the housing 1 is arranged on the housing 1, a clamping block 5 in linkage fit with the rotating shaft 4 is arranged in the housing 1, a return spring is arranged on the clamping block 5, the return spring is respectively abutted against the clamping block 5 and the housing 1, and the clamping block 5 is matched with a plurality of clamping teeth 21 arranged on the rotating disc 2 to circumferentially lock the rotating disc 2.

When carousel 2 is not locked, but free rotation, haulage rope 3 can release or withdraw, and when promoting axis of rotation 4, axis of rotation 4 drives fixture block 5 activity, rotates to latch 21 and fixture block 5 butt when carousel 2 to restriction carousel 2 rotates, and to the opposite direction activity promote axis of rotation 4, return spring makes fixture block 5 return, and latch 21 and fixture block 5 are no longer the butt, but carousel 2 free rotation.

In another embodiment of the present invention, the rotating shaft 4 has a limiting groove 41, and the limiting groove 41 is adapted to a limiting post provided on the housing 1.

In another embodiment of the present invention, the limiting groove is a plurality of grooves arranged uniformly;

the limiting column comprises a hollow column, a spring and a limiting ball which are integrally connected with the shell 1, the spring and the limiting ball are sequentially arranged in the hollow column, one end, far away from the shell 1, of the hollow column is abutted against the rotating shaft 4, and the limiting ball is abutted against the limiting groove.

In another embodiment of the present invention, a hook is provided at an end of the pulling rope 3 away from the rope outlet 12.

In another embodiment of the present invention, the top of the latch 21 has a tip extending downward to form an arc-shaped guide surface.
