Detailed Description

The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the invention provides a dog leash winding and unwinding device, which comprises a housing 1, wherein the housing 1 is formed by connecting a front half shell 101 and a rear half shell 102, a leash outlet 11 is formed in one side of the housing 1, a pivot seat 2 capable of moving close to or far away from the leash outlet 11 is further arranged in the housing 1, a leash winding wheel 3 for winding a dog leash is pivoted on the pivot seat 2, an elastic piece 5 capable of blocking the pivot seat 2 to move close to the leash outlet 11 through elasticity is connected to the pivot seat 2, the elastic piece 5 is a device capable of elastically pulling a rope, such as a spring, an elastic rope, a rubber band and the like, and a limiting device capable of locking the leash winding wheel 3 when the pivot seat 2 moves close to the leash outlet 11 for a certain stroke is further arranged in the housing 1.

In this embodiment, the rope outlet 11 is located at the bottom of the housing 1, and when the pet dog tied with the dog rope runs forward, the dog rope wound on the rope winding wheel 3 is pulled out through the rope outlet 11, and in this process, there is a downward pulling force on the rope winding wheel 3 by the dog rope, so that the pivot seat 2 and the rope winding wheel 3 move downward to be close to the rope outlet 11. The elastic member 5 is stretched while the pivoting seat 2 moves downward. If the speed of the pet dog running forward is smaller than the set limit speed, the pull of the pet dog to the dog rope is small, and after the pin joint seat 2 and the rope winding wheel 3 move downwards for a small distance, the downward pull of the dog rope to the rope winding wheel 3 and the upward pull of the elastic piece 5 to the pin joint seat can reach balance, and the pin joint seat 2 and the rope winding wheel 3 do not move downwards any more. If the speed of the pet dog running forward is greater than the set limit speed, the pulling force of the pet dog on the dog rope is large, the pivot seat 2 and the rope winding wheel 3 are pulled downwards all the time, and when the moving stroke of the pivot seat 2 and the rope winding wheel 3 reaches the set value, the limiting device can lock the rope winding wheel 3 to limit the dog rope to be pulled out continuously. Finally, the dog rope winding and unwinding device can limit the drawing speed of the dog rope wound in the dog rope winding and unwinding device, and when a pet dog runs forward rapidly, the rope winding wheel can be locked by the limiting device and pull the pet dog, so that the pet dog is prevented from being hurt by rapid fleeing.

Referring to fig. 2, in this embodiment, the limiting device includes a ratchet gear 31 disposed at one end or both ends of the rope winding wheel 3, and a limiting bump 16 disposed in the housing 1, where when the rope winding wheel 3 moves along with the pivot seat 2 near the rope outlet 11, the limiting bump 16 can be abutted with a ratchet 311 on the ratchet gear 31 in a matching manner to limit rotation of the rope winding wheel 3.

The above-mentioned limiting device may also be in other structural forms, for example, it includes a soft brake pad disposed in the housing 1 near the rope outlet 11, and when the rope winding wheel 3 moves downward along with the pivot seat 2 to abut against the brake pad, the friction force between the brake pad and the rope winding wheel 3 locks the rope winding wheel 3.

Referring to fig. 2 and 3, one end of the elastic member 5 is connected with the pivot seat 3, the other end is connected with the movable seat 4 which can move in the housing 1 to adjust the elastic force of the elastic member 5, and a gear adjusting device which can adjust the movement stroke of the movable seat 4 is further arranged in the housing 1.

In this embodiment, the gear adjusting device includes a driving member 61 pivoted in the housing 1, the driving member 61 abuts against the movable seat 4 and can push the movable seat 4 to move away from the pivot seat 2 when the driving member 61 rotates, the gear adjusting device further includes a driving member 62 capable of moving in the housing 1, a pressing projection 623 is disposed on the driving member 62, the pressing projection 623 abuts against the driving member 61 and can push the driving member 61 to rotate, a plurality of clamping portions are disposed on the driving member 62 at intervals along the moving direction thereof, and the gear adjusting device further includes an elastic clamping device matched with the clamping portions.

The clamping part is an arc-shaped groove 621 arranged on the driving piece 62, and the elastic clamping device comprises a clamping piece 63 which can move in the shell 1 close to or far from the driving piece 62, and a reset spring 64 for driving the clamping piece 63 to be inserted into the arc-shaped groove 621.

By moving the driving member 62, the driving member 61 can be driven to rotate, and then the moving seat 4 is driven to move up and down to adjust the tension of the elastic member 5, so that the locking member 63 is switched in different arc grooves 621. In the invention, when the rope winding wheel 3 is locked, the corresponding pulling speed of the dog rope is the maximum pulling speed of the dog rope, after the tension of the elastic piece 5 is regulated to be larger, the dog rope needs to have larger downward tension on the rope winding wheel 3 to enable the pivot seat 2 to move downwards until the rope winding wheel 3 is locked, namely, the limit lug 16 can be abutted with the ratchet gear 31. At this time, the maximum pull-out speed of the dog leash becomes greater. Similarly, when the tension of the elastic member 5 is reduced, the maximum pull-out speed of the dog leash becomes smaller.

The gear adjusting device can also adopt a screw, the upper end of the screw is exposed out of the shell, the lower end of the screw passes through the shell 1 and is in threaded connection with the movable seat, a limiting table for limiting the screw to move up and down is further arranged in the shell 1, and the screw is screwed to adjust the stroke of the movable seat 4 to move up and down.

The locking part on the driving piece 62 can also adopt an arc-shaped bulge, and correspondingly, one end of the clamping piece 63, which is close to the driving piece 62, is provided with a groove matched with the bulge.

Referring to fig. 2 and 3, in order to facilitate the movement of the driving member 62 by the user, a pushing portion 622 protruding out of the housing 1 is provided on the driving member 62.

The housing 1 is provided with a handle 12 located beside the push portion 622. The handles enclose an arcuate holding position 17. Such a design can facilitate the user to push 622 to move to adjust the elastic force of the elastic member 5 when holding the present invention, and is ergonomic.

Referring to fig. 3 and 4, in the present embodiment, the movable base 4 includes two connection portions 41 and a pressing post 42 connected between the two connection portions 41, the two connection portions 41 are respectively connected with two ends of the pivot base 2 through the elastic member 5, a pressing arc surface 421 is disposed on one side of the pressing post 42, and the transmission member 61 passes through between the two connection portions 41 and abuts against the pressing arc surface 421. The pivot seat 2 comprises two sliding seats 21 corresponding to the two connecting parts 41 one by one, the elastic piece 5 is connected between the sliding seats 21 and the connecting parts 41 corresponding to each other, the pivot seat 2 further comprises a pivot shaft 22 connected between the two sliding seats 21, and the rope winding wheel 3 is rotatably sleeved on the pivot shaft 22.

Referring to fig. 2, in order to improve the smoothness of the movement of the moving parts, first guide grooves 13 are provided on both side inner walls of the housing 1 to be engaged with the slide carriage 21, and a second guide groove 14 for guiding the moving seat 4 and a third guide groove 15 for guiding the driving piece 62 are also provided in the housing 1.

In order to enable the dog leash to be neatly wound on the reel, the dog leash is prevented from being knotted, a circumferential groove 32 for winding and accommodating the dog leash is arranged in the middle of the rope winding wheel 3, and the width of the circumferential groove 32 is slightly larger than that of the dog leash.
