Description

Technical Field

[0001] The utility model relates to the field of pet products, in particular to a pet traction device with contraction and stretching functions. Background Art

[0002] With the development of the economy, the continuous improvement of people's living standards and the phenomenon of low birth rate, more and more families are starting to keep pets. At present, most families keep pets such as pet dogs and cats. Large animals such as pet dogs and cats are lively and active by nature and like to play with their owners. By interacting with their pets, owners can not only enhance their feelings with their pets, but also exercise their bodies. Usually for the health of their pets, owners take their pets out to play every day. For dogs, we usually call it walking the dog. Dogs are still animals, and there are frequent incidents of dogs injuring people. In order to reduce the harm of dogs to humans, pet owners in cities are usually required to use dog leashes when traveling, but dog leashes cannot solve the adverse events caused by pets running suddenly.

[0003] The prior art (announcement number: CN218218756U, announcement date: 2023-01-06) discloses an explosion-proof traction device, which uses the explosive force of the pet's sudden running to pull the traction rope. When the traction rope is pulled out quickly, the traction rope winder rotates at high speed. The explosion-proof base of the high-speed traction rope winder rotates rapidly, generating centrifugal force, causing the first centrifugal locking component to be swung and rotate along the hinge. The first centrifugal locking component is stuck on the block, thereby preventing the traction rope from continuing to lengthen, preventing the adverse effects caused by the pet's explosive running, and keeping the pet in a controlled state.

[0004] In the above scheme, two centrifugal locks in opposite directions are arranged on the explosion-proof base. When the base rotates at high speed, the outer end of the centrifugal lock will be stuck on the block of the locking piece. However, since the centrifugal lock is a planar structure and is not equipped with a wind resistance structure, centrifugal force will be generated only when the rotation speed of its base reaches a certain level. It is possible to get stuck when the centrifugal force is generated, resulting in the inability to get stuck as long as the speed of the pet's explosion is slightly slower. Therefore, it is necessary to design a lock that is easier to get stuck to solve the problem of pets rushing out and injuring people. In addition, there is only one centrifugal lock in the mechanism to prevent pets from rushing out. After using it for a period of time, it may not be completely stuck, resulting in damage to the device and the need for overall replacement, which is costly. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1-7 As shown, a pet traction device with a contraction and stretching function of the utility model comprises a telescopic box 1 and a pull rope 2;

[0036] The telescopic box 1 is provided with a base 3 in a clearance fit, a rotating seat 4 is rotatably fitted on the base 3, a spring clip 5 is provided between the base 3 and the rotating seat 4, the inner end of the pull rope 2 is fixedly mounted on the rotating seat 4, the pull rope 2 is wound around the outer side of the rotating seat 4, and the outer end of the pull rope 2 is provided outside the telescopic box 1;

[0037] A plurality of wind resistance buckles 6 are rotatably mounted on the rotating seat 4, and a plurality of limiting protrusions 7 are formed on the rotating seat 4. The limiting protrusions 7 are arranged one by one on the outside of the wind resistance buckle 6. A reset tension spring 8 is fixedly installed between the wind resistance buckle 6 and the rotating seat 4. A plurality of limiting slots 9 are formed on the top side of the telescopic box 1. When the wind resistance buckle 6 is opened, it is stuck in the limiting slot 9.

[0038] The principle is: a wind resistance buckle 6 is set, and when the rotating seat 4 rotates at high speed, the wind resistance buckle 6 will generate centrifugal force and wind resistance in the telescopic box 1, and then quickly open and get stuck in the limit slot 9, thereby limiting the pull rope 2 from being pulled out, thereby preventing the pet from rushing out. Compared with the prior art, the utility model sets a plurality of wind resistance buckles 6, which can be stuck in the corresponding limit slots 9 at the same time. As long as one wind resistance buckle 6 is stuck in the limit slot 9, the rotation of the rotating seat 4 can be limited. The clamping effect is better, the service life is longer, and the rotation speed requirement is lower, so that the rotating seat 4 is easier to get stuck, thereby effectively preventing the pet from rushing out and injuring people.

[0039] Furthermore: a wind resistance edge 10 is formed at the outer edge of the wind resistance buckle 6; the wind resistance edge 10 can be used to increase the wind resistance when the wind resistance buckle 6 rotates, and the wind resistance and centrifugal force can be effectively used to drive the wind resistance buckle 6 to open without an excessively high rotation speed, thereby achieving a quick locking effect and effectively preventing the pet from rushing out.

[0040] Furthermore: the wind resistance edge 10 and the bottom edge of the wind resistance buckle 6 are arranged perpendicular to each other; they can better receive the wind resistance to drive the wind resistance buckle 6 to open.

[0041] Furthermore: a limited edge 11 is formed in the middle part of the upper side of the rotating seat 4, and the reset tension spring 8 pulls the wind resistance buckle 6 and makes the wind resistance buckle 6 abut against the limited edge 11; this makes the reset of the wind resistance buckle 6 more stable. After the pet is stuck in the burst, as long as the pull rope 2 is no longer in a tightened state, the reset tension spring 8 can drive the wind resistance buckle 6 to reset. After the wind resistance buckle 6 is reset, the pull rope 2 can be pulled out normally, which is convenient for actual use.

[0042] Furthermore: the direction of one of the wind resistance buckles 6 is set opposite to the direction of the other wind resistance buckles 6; when the pull rope 2 is loosened, the pull rope 2 will be retracted into the telescopic box 1 through the spring clip 5, and the wind resistance buckles 6 in the opposite direction can prevent the pull rope 2 from being retracted too quickly. When the rotating seat 4 rotates too quickly, the wind resistance buckles 6 in the opposite direction will be stuck in the corresponding limit slot 9, thereby limiting the rotating seat 4 from continuing to rotate, which can prevent the pull rope 2 from being retracted too quickly and causing harm to the pet.

[0043] Furthermore: a positioning column 12 is formed in the middle of the upper side of the base 3, a cutout 13 is formed on the positioning column 12, a circular hole 14 is formed in the middle of the rotating seat 4, the positioning column 12 is rotatably installed in the circular hole 14, the spring clip 5 is installed in the rotating seat 4, the middle part of the spring clip 5 is plugged into the cutout 13 of the positioning column 12, and the outer end of the spring clip 5 is fixedly installed on the rotating seat 4; this makes the installation of the spring clip 5 more stable.

[0044] Furthermore, a fixing bolt 15 is fixedly installed at the inner end of the pull rope 2, and the fixing bolt 15 is fixedly installed on the rotating seat 4, so that the installation of the pull rope 2 on the rotating seat 4 is more stable and the winding effect is better.

[0045] Further: the telescopic box 1 includes a face cover 1-1 and an upper cover 1-2, the upper cover 1-2 is installed in the face cover 1-1 with a clearance fit, the base 3 is fixed to the bottom side of the upper cover 1-2 by screws, and the limit slot 9 is integrally formed in the upper cover 1-2; the face cover 1-1 can be fixed on the pet vest 19 for use, which can effectively prevent the pet from bursting out.

[0046] Furthermore, a swivel buckle 16 is fixedly mounted on the outer end of the pull rope 2 , a handle 17 is fixedly mounted on the swivel buckle 16 , and a decorative cover 18 is also fixedly mounted on the pull rope 2 ; this facilitates the pulling and use of the pull rope 2 .

[0047] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
