Description

Technical Field

[0001] This utility model relates to the field of pet leash technology, and in particular to an anti-accidental opening buckle suitable for pet leashes. Background Technology

[0002] Pet leash buckle technology has been continuously developing, evolving from simple hooks to multi-functional buckles with high safety, durability, and ease of operation. Anti-accidental opening buckle design has become one of the key technologies for improving pet safety and reducing accidents. With the advancement of materials science, structural design, and intelligent technology, future buckles will be safer, more convenient, and more intelligent.

[0003] A leash is a common pet leash tool, typically consisting of a hook, a leash body, an internal spring assembly, and a connecting ring. The hook is designed to securely attach to a pet collar or harness, and may take the form of a straight hook or a swivel hook. The leash body is usually made of sturdy materials such as stainless steel or aluminum alloy to ensure durability and corrosion resistance. The internal spring assembly helps to automatically reset the locking mechanism to prevent accidental release. The connecting ring is used to connect the leash to the leash for increased flexibility in use.

[0004] In existing technologies, some pet leash buckles have the problem of accidental opening, mainly due to the weak design of the buckle locking mechanism and the easy accidental activation of the switch button. This not only affects the safety of the pet, but also causes the leash to loosen, posing a potential danger to the pet. Therefore, an anti-accidental opening buckle suitable for pet leashes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-accidental opening buckle for pet leashes, aiming to improve the problem of accidental opening of some pet leash buckles in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A limit ring is fixedly connected to the outside of the rotating rod. Multiple fixing blocks are fixedly connected to the top of the limit ring. A locking component is fixedly connected to the top of the fixing blocks. Two connecting posts are slidably connected to both ends of one side of the buckle body. A connecting rod is fixedly connected to one side of each connecting post. A connecting block is fixedly connected to the bottom of each connecting rod. A spring is fixedly connected to the adjacent sides of the two connecting rods. A connecting ring is provided inside the buckle body. A protective shell is provided inside the connecting ring.

[0008] As a further description of the above technical solution:

[0009] The locking assembly includes a spring, the top of which is fixedly connected to a movable ring, and the bottom of which is fixedly connected to the top of the fixing block.

[0010] As a further description of the above technical solution:

[0011] The protective shell 1 is rotatably connected to a telescopic rod 1, and a spring 3 is sleeved on the outside of the telescopic rod 1. A limit block 1 is fixedly connected inside the protective shell 1. A rotating block 1 is rotatably connected to one end of the spring 3. A rotating block 2 is engaged with one side of the limit block 1. A protective shell 2 is rotatably connected to one side of the rotating block 2. A telescopic rod 2 is rotatably connected inside the protective shell 2. A spring 4 is sleeved on the outside of the telescopic rod 2. A limit block 2 is fixedly connected inside the protective shell 2.

[0012] As a further description of the above technical solution:

[0013] A fixing pin is fixedly connected to the top of one side of the buckle body, and a limiting ring two is fixedly connected to the bottom of one side of the buckle body. Multiple wedge blocks are fixedly connected to the bottom of the limiting ring two.

[0014] As a further description of the above technical solution:

[0015] The bottom of the wedge block contacts the inside of the moving ring, and the connecting rod is slidably connected inside the buckle body;

[0016] As a further description of the above technical solution:

[0017] The rotating rod has a groove inside, and the connecting block engages with the groove inside the rotating rod.

[0018] As a further description of the above technical solution:

[0019] One end of the spring three is fixedly connected to the inner wall of the protective shell one, and the other end of the spring three is fixedly connected to one side of the rotating block one.

[0020] As a further description of the above technical solution:

[0021] One end of the spring four is fixedly connected to the inner wall of the protective shell two, and the other end of the spring four is fixedly connected to one side of the rotating block two.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by moving the moving ring towards the spring, the moving ring disengages from the wedge block, releasing the fixation on the buckle body. Then, the connecting post can be pressed, causing the connecting rod and connecting block to move, disengaging the connecting block from the internal engagement with the rotating rod. This facilitates opening the buckle, allowing the ring on the pet to be placed inside. After connection, the rotating rod returns to its original position, the connecting post is released, and the compressed spring pushes the connecting rod, causing the connecting block to engage with the internal groove of the rotating rod. Subsequently, the moving ring is released, and the compressed spring pushes the moving ring to engage with the wedge block, achieving a secure connection of the ring on the pet. The operation is simple and the connection is stable, effectively ensuring the safety and reliability of the pet wearing the ring.

[0024] 2. In this utility model, the limiting block two drives the rotating block one to rotate, which in turn causes the spring three and the telescopic rod one to extend and retract. At the same time, the limiting block one drives the rotating block two to rotate, which causes the spring four and the telescopic rod two to extend and retract. When the rotating block one and the rotating block two move to the fitting position, they form a circle. At this time, the spring three and the telescopic rod one, as well as the spring four and the telescopic rod two, respectively drive the rotating block one and the rotating block two to rotate, thus achieving automatic locking. This design not only realizes the convenient connection between the buckle and the leash, ensuring the firmness and stability of the connection, but also effectively prevents accidental separation during use, providing reliable protection for the safety of pets when traveling, and greatly improving the user experience.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an anti-accidental opening buckle for pet leashes, comprising a buckle body 1, a fixing pin 2 fixedly connected to the top of one side of the buckle body 1, the fixing pin 2 being used to stably connect a rotating rod 3 to the buckle body 1, ensuring that the rotating rod 3 can rotate around a fixed point as an axis, the rotating rod 3 being rotatably connected to the top of one side of the buckle body 1, the rotating rod 3 being one of the key components for realizing the opening and closing of the buckle, achieving connection and separation with the leash on the pet through rotation, a limiting ring 4 being fixedly connected to the outside of the rotating rod 3, the limiting ring 4 being able to limit the rotation range of the rotating rod 3, preventing excessive rotation that could cause the buckle to malfunction or pose a safety hazard.

[0033] The top of the limiting ring 4 is fixedly connected to multiple fixing blocks 5, and the top of the fixing blocks 5 is fixedly connected to a locking component. The fixing blocks 5 provide a fixed base for the locking component, enabling the locking component to function stably. The locking component is the core part that prevents the buckle from being accidentally opened. It can firmly lock the buckle after it is connected. The locking component includes a spring 6, and the top of the spring 6 is fixedly connected to a moving ring 7. The spring 6 is an elastic component in the locking component. It uses its own elastic force to move the moving ring 7 up and down, thereby controlling the locking and unlocking state of the buckle. The bottom of the spring 6 is fixedly connected to the top of the fixing blocks 5, ensuring that the spring 6 can be stably installed on the fixing blocks 5 and providing stable elastic support for the moving ring 7.

[0034] A limiting ring 2 9 is fixedly connected to the bottom of one side of the buckle body 1. Multiple wedge blocks 8 are fixedly connected to the bottom of the limiting ring 2 9. The limiting ring 2 9 is used to fix the wedge blocks 8 so that they can accurately cooperate with the moving ring 7. The wedge blocks 8 and the moving ring 7 cooperate with each other. When the moving ring 7 is engaged with the wedge blocks 8, it can prevent the rotation of the rotating rod 3, thereby locking the buckle and preventing accidental opening. The bottom of the wedge blocks 8 is in contact with the inside of the moving ring 7. This contact method allows the moving ring 7 to accurately engage or disengage with the wedge blocks 8 when moving, ensuring the smooth realization of the locking and unlocking functions.

[0035] Two connecting posts 10 are slidably connected to both ends of one side of the buckle body 1. A connecting rod 11 is fixedly connected to one side of the connecting post 10, and a connecting block 12 is fixedly connected to the bottom of the connecting rod 11. The connecting post 10 can slide on the buckle body 1, and its movement drives the movement of the connecting rod 11 and the connecting block 12, thereby controlling the locking and unlocking of the rotating rod 3. The connecting rod 11 transmits the movement of the connecting post 10 to the connecting block 12, so that the connecting block 12 can engage or disengage with the groove inside the rotating rod 3. The connecting rod 11 is slidably connected inside the buckle body 1, ensuring that the connecting rod 11 can slide smoothly inside the buckle body 1, and also providing it with a certain guiding and supporting function. The connecting block 12 is the component that engages with the groove inside the rotating rod 3. By engaging and disengaging with the rotating rod 3, the rotation of the rotating rod 3 is controlled, thereby realizing the opening and closing of the buckle.

[0036] The rotating rod 3 has a groove inside, which cooperates with the connecting block 12. When the connecting block 12 is engaged in the groove, the rotating rod 3 is locked and cannot rotate. When the connecting block 12 is disengaged from the groove, the rotating rod 3 can rotate freely, realizing the opening or closing of the buckle. The engagement of the connecting block 12 with the groove inside the rotating rod 3 is an important mechanism to ensure that the buckle will not be accidentally opened during normal use. The buckle can only be opened by manually disengaging the connecting block 12 from the groove. A second spring 13 is fixedly connected to the adjacent side of the two connecting rods 11. The second spring 13 is compressed when the connecting post 10 is pressed. When the connecting post 10 is released, the second spring 13 releases its elastic force, pushing the connecting rod 11 to move outward, so that the connecting block 12 re-engages with the groove inside the rotating rod 3, realizing the automatic locking of the buckle.

[0037] The buckle body 1 has a connecting ring 14 inside, and a protective shell 15 inside the connecting ring 14. The connecting ring 14 provides an installation position for the protective shell 15, and also plays a certain role in connection and fixation, so that the protective shell 15 can be stably installed inside the buckle body 1. The protective shell 15 is used to accommodate and protect components such as the telescopic rod 16, the spring 17, and the limiting block 18. It also cooperates with the protective shell 22 to further lock the connection between the buckle and the traction rope.

[0038] Reference Figure 1 and Figure 4The protective shell 15 has a telescopic rod 16 rotatably connected inside, and a spring 3 17 is sleeved on the outside of the telescopic rod 16. The telescopic rod 16 can rotate and extend within the protective shell 15. The spring 3 17 provides elastic force to the telescopic rod 16, so that it can generate a certain resistance and restoring force during rotation and extension. The protective shell 15 has a fixed limit block 18 inside, and a rotating block 19 is rotatably connected to one end of the spring 3 17. A rotating block 20 is engaged on one side of the limit block 18. The limit block 18 is used to limit the rotation range of the rotating block 20, ensuring that the rotating block 20 can be accurately positioned when engaged with the limit block 18, so that the rotating block 19 and the rotating block 20 can smoothly form a circle and achieve locking.

[0039] Spring 3 17 drives rotating block 1 19 to rotate through its own elastic force, so that rotating block 1 19 can cooperate with rotating block 2 20. When protective shell 1 15 and protective shell 2 22 are connected, the buckle and the traction rope are locked. One end of spring 3 17 is fixedly connected to the inner wall of protective shell 1 15, providing a fixed support point for spring 3 17, so that it can stably exert its elastic effect and drive rotating block 1 19 to rotate and extend. The other end of spring 3 17 is fixedly connected to one side of rotating block 1 19, ensuring that the elastic force of spring 3 17 can be effectively transmitted to rotating block 1 19, so that rotating block 1 19 can rotate and move according to the design requirements.

[0040] Rotating block 20 rotates under the restriction of limiting block 18, cooperating with rotating block 19 to lock the buckle and traction rope connection. The engagement of the two ensures stability and accuracy during docking. One side of rotating block 20 is rotatably connected to protective shell 22, which provides support and protection for the rotation of rotating block 20. It also cooperates with protective shell 15 to drive rotating block 20 to rotate and move accordingly during docking, thus realizing the entire locking process. Inside protective shell 22, telescopic rod 24 is rotatably connected. Telescopic rod 24 rotates and extends within protective shell 22, cooperating with spring 4 23 to adjust the position and state of rotating block 20 according to the docking situation of protective shell 15 and protective shell 22, ensuring accurate cooperation with rotating block 19.

[0041] The telescopic rod 24 is externally fitted with a spring 23, which provides elastic force to the telescopic rod 24, enabling the telescopic rod 24 to drive the rotating block 20 to move accordingly when rotating and extending. It works in conjunction with the rotating block 19 to lock and unlock the buckle and the traction rope connection. The protective shell 22 is internally fixedly connected with a limit block 21, which limits the rotation range of the rotating block 19. When the protective shell 15 and the protective shell 22 are docked, the rotating block 19 is driven to rotate, so that it can accurately fit and form a circle with the rotating block 20, thus achieving the locking function.

[0042] One end of spring 4 23 is fixedly connected to the inner wall of protective shell 2 22, providing a fixed support point for spring 4 23 so that it can stably exert its elastic effect and drive telescopic rod 2 24 and rotating block 2 20 to perform corresponding movements. The other end of spring 4 23 is fixedly connected to one side of rotating block 2 20, ensuring that the elastic force of spring 4 23 can be effectively transmitted to rotating block 2 20, so that rotating block 2 20 can cooperate with rotating block 1 19 under the action of spring 4 23 and telescopic rod 2 24 to complete the locking operation of the buckle and the traction rope connection.

[0043] Working principle: First, the user needs to move the moving ring 7 towards the direction of spring 6. This movement disengages the moving ring 7 from the wedge block 8, causing it to release from its fixation to the buckle body 1. Then, the user can press the connecting post 10, which moves the connecting rod 11, which in turn moves the connecting block 12. The connecting block 12 then disengages from its internal engagement with the rotating rod 3, allowing the user to press the rotating rod 3 and open the buckle, thus allowing the pet to be removed. Once the ring is placed in the buckle, the rotating rod 3 can be returned to its original position after connection, and the connecting post 10 can be released. As a result, the spring 13, due to being compressed, will exert an outward pushing force on the connecting rod 11. The movement of the connecting rod 11 will drive the connecting block 12 to move, and the connecting block 12 will engage with the groove inside the rotating rod 3. Then the moving ring 7 can be released, and the spring 6, due to being compressed, will push the moving ring 7 to move, and the moving ring 7 will engage with the wedge block 8, thereby achieving the docking of the ring on the pet.

[0044] Once the buckle is aligned with the ring on the pet, protective shell 15 and protective shell 22 can be connected. The movement of limit block 21 will cause rotating block 19 to rotate, which in turn will cause spring 3 17 and telescopic rod 16 to extend and retract. Simultaneously, the movement of limit block 18 will cause rotating block 20 to rotate, which in turn will cause spring 4 23 and telescopic rod 24 to extend and retract. One side of rotating block 19 will then align with one side of rotating block 20. After moving to a certain position, rotating block 19 and rotating block 20 will form a circle. Spring 3 17 and telescopic rod 16 will then cause rotating block 19 to rotate, and spring 4 23 and telescopic rod 24 will then cause rotating block 20 to rotate, thus achieving the locking purpose and connecting the buckle to the leash.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
