Description

Technical Field

[0001] This invention relates to the field of dog management equipment technology, specifically a multi-form dog leash device with integrated control and emergency bite relief functions. Background Technology

[0002] Existing dog leashes are mostly simple leash or harness structures with limited functionality, primarily used for daily walks and control. When dogs become uncontrollably aggressive, attack others, or accidentally bite foreign objects, traditional leashes cannot provide effective behavioral intervention or emergency bite relief. While some existing technologies have proposed improvements with muzzles or restraints, these are usually structurally separate, inconvenient to carry, and cannot be quickly switched between daily leashing and emergency situations. Especially in emergency situations where a dog's jaws are clenched after biting, the lack of a tool to quickly and safely pry open the dog's jaws makes rescue difficult and increases the risk of secondary injury. Therefore, developing a multifunctional dog leash device that can meet both daily leashing and control needs and respond to sudden attacks or bite incidents has significant practical value. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-form dog leash with integrated control and emergency bite relief functions to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-form dog traction device with integrated control and emergency bite rescue functions, comprising a folding stick assembly, wherein the folding stick assembly is formed by connecting a first rigid long rod and a second rigid long rod through an intermediate hinge mechanism, wherein the intermediate hinge mechanism is provided with an elastic element and a locking and releasing mechanism, so that the stick assembly has mutually convertible extended locking form and folded open form. A grip handle housing has an internal storage cavity, in which the folding stick assembly is detachably housed. The grip handle housing also has a connecting part for connecting a traction rope. A flexible restraint system includes at least one flexible restraint strap and a self-locking tightening mechanism, the flexible restraint system being detachably fixed to the grip handle housing and being removable for independent use; When the foldable stick assembly is in the extended and locked state, it can be suspended below the dog's neck via a suspension member to interfere with the movement of the forelegs. When the foldable stick assembly is in the folded and open state, it can be inserted into the dog's mouth to open the upper and lower jaws. After the flexible restraint system is removed, it can wrap around the dog's mouth, neck, or legs and tighten.

[0005] Furthermore, the intermediate hinge mechanism includes: a hinge seat, fixedly connected to the end of the first rigid long rod; A hinge shaft is fixedly connected to the end of a second rigid long rod and rotatably engages with the hinge seat; The elastic element is a torsion spring mounted on the hinge shaft, with its two ends abutting against the first rigid rod and the second rigid rod, respectively. The locking and releasing mechanism is a sliding locking block, which is located between the hinge seat and the hinge shaft, and is used to lock the rod assembly in the straightened locking state.

[0006] Furthermore, the flexible restraint system also includes a detachable mouth restraint attachment, which has a semi-enclosed shell structure and a connecting clip at its end. When the end of the flexible restraint strap is connected to the connecting clip, the flexible restraint strap and the mouth restraint attachment together constitute a mouth binding assembly. When the flexible restraint strap is detached from the mouth restraint attachment and used alone, it constitutes a leg binding assembly.

[0007] Furthermore, the grip handle housing is provided with an independent storage compartment with a flip-top cover at the opening of the storage compartment. The flexible restraint system is placed in the storage compartment in a coiled state. After pressing the elastic buckle or opening the cover, the flexible restraint system will at least partially pop out of the storage compartment.

[0008] Furthermore, the folding rod assembly is connected to a collar hook via a flexible cable. One end of the flexible cable is fixedly connected to the outer shell of the intermediate hinge mechanism or the shaft of any rigid long rod, and the other end of the flexible cable is fixedly connected to the collar hook. The length of the flexible cable is 8cm to 25cm.

[0009] Furthermore, the self-locking tightening mechanism includes: A frame with a through-through strap channel inside; A resilient latch, hinged or elastically connected to the frame, has its free end extending into the strap passage; The surface of the flexible restraint strap is provided with multiple one-way teeth arranged along the length direction or a surface with a high coefficient of friction. When the flexible restraint strap passes through the strapping channel, the elastic locking tongue presses against the one-way teeth or the surface with a high coefficient of friction to form a one-way locking. The frame is also equipped with a release button. When the release button is pressed, the elastic locking tongue disengages from the contact with the flexible restraint strap.

[0010] Furthermore, in the folded-out state, the angle between the first rigid rod and the second rigid rod is limited to between 30° and 70°. When the foldable rod assembly is in the folded-out state, flexible protective end sleeves are respectively provided at the ends of its two rigid rods.

[0011] Furthermore, the grip handle housing is elongated, with an internal storage cavity extending along the length of the handle. The folding rod assembly is inserted entirely into the storage cavity in the straightened and locked state. The tail of the grip handle housing is provided with an end cap or elastic buckle to prevent the rod assembly from coming out. The front end or side of the grip handle housing is provided with the traction rope connection part.

[0012] Furthermore, both the first and second rigid rods are hollow aluminum alloy tubes or carbon fiber tubes, each with a length of 12cm to 20cm, and a total length of 24cm to 40cm when straightened. The flexible restraint strap is a nylon webbing with a length of 120cm to 250cm, a width of 10mm to 30mm, and a breaking force of not less than 150kg.

[0013] Furthermore, the locking release mechanism is a sliding locking block, which is installed on the housing of the intermediate hinge mechanism and slides in a direction perpendicular to the hinge axis. When the rod assembly is in the extended locking state, the sliding locking block extends into the locking hole between the hinge seat and the hinge axis. When the sliding locking block is pushed out of the locking hole, the elastic element drives the first rigid rod and the second rigid rod to rotate relative to each other to the folded open state.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention integrates a daily traction handle, a behavior control bar, and an emergency bite mouth opener into the same device. By switching between the straightening and folding opening modes of the folding stick assembly and the independent removal and use of the flexible restraint system, it can achieve multiple functions such as walking traction, front leg interference control, emergency mouth opening, and mouth or leg restraint, meeting the dog management needs in different scenarios.

[0015] 2. The folding stick assembly automatically unfolds to a preset angle after unlocking via an elastic element, allowing it to be quickly inserted into the dog's mouth to open the upper and lower jaws, providing effective operating space for removing foreign objects or releasing the bite; the rigid long stick has a flexible protective end cap to avoid secondary damage to the dog's mouth, significantly improving the safety and response speed of emergency treatment.

[0016] 3. The flexible restraint system is stored in a coiled state in an independent storage compartment in the handle housing. Opening the compartment cover will pop out at least part of it, making it quick to use. The self-locking tightening mechanism can achieve one-way locking and one-button release, and is equipped with a detachable muzzle restraint accessory. It can quickly assemble muzzle, neck or leg restraint components according to actual needs. The structure is compact, the operation is simple, and it is suitable for dogs of different sizes and different emergency scenarios. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figures 1-8 As shown, this invention provides a multi-form dog leash device with integrated control and emergency bite relief functions, including a folding rod assembly 1. The folding rod assembly 1 is formed by connecting a first rigid long rod 11 and a second rigid long rod 12 through an intermediate hinge mechanism 2. The intermediate hinge mechanism 2 is provided with an elastic element and a locking and releasing mechanism 5, so that the rod assembly has an interchangeable straightened and locked form and a folded and unfolded form. A grip handle housing 3 has a storage cavity inside, and the folding stick assembly 1 is detachably housed in the storage cavity. The grip handle housing 3 also has a connecting part for connecting a traction rope. A flexible restraint system 4 includes at least one flexible restraint strap and a self-locking tightening mechanism. The flexible restraint system 4 is detachably fixed to the grip handle housing 3 and can be removed as a whole for independent use. When the foldable stick assembly 1 is in the extended and locked state, it can be suspended below the dog's neck by the suspension member to interfere with the movement of the forelegs. When the foldable stick assembly 1 is in the folded and open state, it can be inserted into the dog's mouth to open the upper and lower jaws. After the flexible restraint system 4 is removed, it can wrap around the dog's mouth, neck or legs and tighten. When in use, this device can quickly switch between different modes according to the actual scenario to meet different needs such as walking and leash control, behavior control, and emergency bite control: During daily dog ​​walking, the folding stick component 1 is stored in the storage cavity of the handle housing 3, and the handle is connected to the leash via the connecting part, which can be used as a regular leash handle, providing a stable grip and easy control of the dog's movement; when the dog goes out of control and bites or does not obey commands, the folding stick component 1 can be taken out and adjusted to the straightened and locked form, and suspended below the dog's neck via the suspension device to restrict the dog's front leg lifting and biting actions, achieving rapid behavior control; once the dog accidentally bites a foreign object, or bites and its jaws are clenched and cannot be released. In an emergency, the folding stick assembly 1 can be adjusted to a folded open shape, inserted between the dog's teeth, and its shape can be used to open the dog's upper and lower jaws, which can remove foreign objects and quickly release the dog from the biting state. If it is necessary to further fix and restrict the dog's movements, the flexible restraint system 4, which is pre-installed on the handle housing 3, can be taken out and wrapped around the dog's mouth to tighten and fix it, preventing it from biting again. It can also be wrapped around the neck or legs as needed to adapt to different emergency treatment scenarios. This device integrates multiple functions and has a flexible form conversion. It can be used for daily leash use and can also be used to quickly carry out emergency treatment in case of emergencies, improving the convenience of dog management and emergency rescue.

[0020] The intermediate hinge mechanism 2 includes: a hinge seat 21, which is fixedly connected to the end of the first rigid long rod 11; A hinge shaft 22 is fixedly connected to the end of the second rigid long rod 12 and rotatably engages with the hinge seat 21; The elastic element is a torsion spring mounted on the hinge shaft 22, with its two ends abutting against the first rigid rod 11 and the second rigid rod 12, respectively. The locking release mechanism 5 is a sliding locking block 51, which is disposed between the hinge seat 21 and the hinge shaft 22, and is used to lock the rod assembly in the straightened locking state. Furthermore, when the intermediate hinge mechanism 2 is in use, the torsion spring will continuously apply a deflection force to the two rigid rods. When the sliding lock block 51 is unlocked, the two rigid rods will automatically rotate and unfold into a folded open state under the action of the torsion spring. There is no need to manually open and adjust, which can quickly achieve the form switching. In emergency rescue scenarios, the unfolding operation can be completed more quickly, saving preparation time for emergency response. The structure is simple and reliable, the transmission response is fast, and it can meet the use requirements of rapid form switching.

[0021] The flexible restraint system 4 also includes a detachable mouth restraint attachment 41, which has a semi-enclosed shell structure and a connecting clip at its end. When the end of the flexible restraint strap is connected to the connecting clip, the flexible restraint strap and the mouth restraint attachment 41 together constitute a mouth binding assembly. When the flexible restraint strap is detached from the mouth restraint attachment 41 and used alone, it constitutes a leg binding assembly. When in use, the semi-enclosed muzzle restraint attachment 41 can conform to the contour of the dog's mouth and nose. When tightened with the flexible restraint strap, it can more stably fix the dog's muzzle, preventing the soft restraint strap from slipping and loosening, thus improving the reliability of the muzzle restraint. When it is necessary to fix the legs or neck, the muzzle restraint attachment 41 can be removed to allow the flexible restraint strap to flexibly adapt to the binding needs of different parts, taking into account both the stability of the restraint and the flexibility of use, and adapting to a variety of emergency response scenarios.

[0022] The handle housing 3 has an independent storage compartment 31 with a flip cover 32 at the opening. The flexible restraint system 4 is placed in the storage compartment 31 in a coiled state. After pressing the elastic buckle or opening the cover, the flexible restraint system 4 will at least partially pop out of the storage compartment 31. When in use, the independent storage compartment 31 of the handle housing 3 can store the flexible restraint system 4 separately without interfering with the folding rod assembly 1 in the storage cavity. When in use, the flexible restraint system 4 can be quickly taken out by opening the compartment cover without having to search and organize. The rolled storage method can also avoid the flexible restraint strap from getting tangled and stuck, ensuring smooth and convenient access in emergencies and improving access efficiency.

[0023] The folding stick assembly 1 is connected to a collar hook via a flexible cable. One end of the flexible cable is fixedly connected to the outer shell of the intermediate hinge mechanism 2 or to the shaft of any rigid long rod, and the other end of the flexible cable is fixedly connected to the collar hook. The length of the flexible cable is 8cm to 25cm. When in use, the folding stick component 1 is long enough to fit dogs of different sizes. In its extended and locked state, it can be quickly hung on the collar worn by the dog via the collar hook. It is suspended below the dog's neck by a flexible cable, which will not affect the dog's normal breathing. At the same time, it can stably interfere with the dog's front leg lifting action to prevent the dog from biting. When this state is not needed, it can be folded and stored back in the handle housing 3 without taking up extra space. The structure is compact and reasonable, and it meets the dual needs of daily walking and control.

[0024] The self-locking tightening mechanism includes: A frame 42, with a through-through strap channel inside; A resilient locking tongue 43 is hinged or elastically connected to the frame 42, and the free end of the resilient locking tongue 43 extends into the strapping channel; The surface of the flexible restraint strap is provided with multiple one-way teeth arranged along the length direction or a surface with a high coefficient of friction. When the flexible restraint strap passes through the strapping channel, the elastic locking tongue 43 presses against the one-way teeth or the surface with a high coefficient of friction to form a one-way locking. The frame 42 is also provided with a release button. When the release button is pressed, the elastic locking tongue 43 disengages from the contact with the flexible restraint strap. The self-locking tightening mechanism allows for quick tightening simply by pulling the flexible restraint strap, eliminating the need for complicated operations. In emergencies, tightening can be done with one hand. To loosen the restraint, simply press the release button to quickly release the lock. The operation is simple and efficient, ensuring the reliability of the restraint while allowing for quick adjustment of the tightening degree according to actual needs. It adapts to the restraint requirements of different body types and body parts, improving the efficiency of emergency response.

[0025] In the folded-out state, the included angle between the first rigid rod 11 and the second rigid rod 12 is limited to between 30° and 70°. When the foldable rod assembly 1 is in the folded-out state, flexible protective end sleeves are respectively provided at the ends of its two rigid rods. When in use, the device's opening angle of 30° to 70° can accommodate the mouth opening size of most dogs. It can stably open the upper and lower jaws to provide sufficient operating space without causing additional damage to the dog's mouth due to an excessive opening angle. The flexible protective sleeve at the end can prevent the rigid long rod from scratching the soft tissue of the dog's mouth, improving operational safety and preventing secondary injury to the dog during emergency rescue bites.

[0026] The handle housing 3 is elongated, with an internal storage cavity extending along the length of the handle. The folding stick assembly 1 is inserted into the storage cavity in the straightened and locked state. The tail of the handle housing 3 is provided with an end cap or elastic buckle to prevent the stick assembly from coming out. The front end or side of the handle housing 3 is provided with the traction rope connection part. When the folding baton assembly 1 is fully stowed in its extended and locked state, its overall outer diameter matches the outer diameter of the handle housing 3, without any additional protrusion affecting the grip. It is comfortable and easy to hold during daily use, and the traction control is more stable. The end cap or elastic buckle prevents the folding baton assembly 1 from accidentally sliding out of the storage cavity during daily traction. When needed, the baton assembly can be quickly taken out by opening the end cap or unlocking the elastic buckle. The structural design meets the different needs of daily use and emergency access, improving both safety and convenience.

[0027] The first rigid long rod 11 and the second rigid long rod 12 are both hollow aluminum alloy tubes or carbon fiber tubes, each with a length of 12cm to 20cm, and a total length of 24cm to 40cm when straight. The flexible restraint band is a nylon webbing with a length of 120cm to 250cm, a width of 10mm to 30mm, and a breaking force of not less than 150kg. Because the first rigid long rod 11 and the second rigid long rod 12 are made of hollow and lightweight materials, while ensuring sufficient structural strength to support the opening action, the overall weight is effectively reduced. Users will not experience excessive fatigue when holding them for a long time, making them convenient to carry when walking the dog. The appropriate length can meet the needs of opening the mouth and suspending the neck of dogs of different sizes, and it is not too long or too large when stored, making it easy to hold and carry. The flexible restraint strap made of nylon webbing is strong and tough. Its sufficient length can adapt to the restraint needs of different parts of dogs of different sizes, and its sufficient width and breaking force can ensure that it will not break or loosen after tightening, improving the reliability of emergency restraint and taking into account portability, strength and safety of use.

[0028] The locking release mechanism 5 is a sliding locking block 51. The sliding locking block 51 is installed on the housing of the intermediate hinge mechanism 2 and slides in a direction perpendicular to the axis of the hinge shaft 22. When the rod assembly is in the extended locking state, the sliding locking block 51 extends into the locking hole between the hinge seat 21 and the hinge shaft 22. When the sliding locking block 51 is pushed out of the locking hole, the elastic element drives the first rigid rod 11 and the second rigid rod 12 to rotate relative to each other to the folded open state. When using the locking and releasing mechanism 5 of this device, the user can quickly push the sliding lock block 51 with their thumb to complete the unlocking operation. The form switching can be completed with one hand, without the need for two hands to cooperate. In emergency situations, it can be unfolded more quickly, with a fast response speed and a simple and direct operation path. Even in the event of a sudden loss of control by the dog, it can be unlocked and opened quickly without delaying the response due to complicated operation. The structure is simple and the locking is reliable, and there will be no situation of mis-locking or inability to unlock, ensuring the reliability of form switching.

[0029] Working Principle: This device can quickly switch between different modes depending on the actual scenario, meeting various needs such as walking and leash control, behavior control, and emergency bite control. During daily dog ​​walks, the folding stick assembly 1 is stored in the storage cavity of the handle housing 3. The handle is connected to the leash via a connector, allowing it to be used as a regular leash handle, providing a stable grip and easy control of the dog's movement. When the dog becomes uncontrollable and bites, or disobeys commands, the folding stick assembly 1 can be removed and adjusted to a straightened and locked position. It is then suspended below the dog's neck via a suspension device, restricting the dog's front leg lifting and biting movements, achieving rapid behavior control. In the event of the dog accidentally biting a foreign object or biting someone and then clenching its jaws, the device can be used to control the dog's behavior. In an emergency where the dog's leash comes loose, the folding stick assembly 1 can be adjusted to a folded, open position. Inserted between the dog's teeth, the folded shape can be used to open the upper and lower jaws, removing the foreign object and quickly releasing the dog from its biting state. If further restraint is needed, the flexible restraint system 4, pre-installed on the handle housing 3, can be removed and wrapped around the dog's mouth to tighten and secure it, preventing further biting. It can also be wrapped around the neck or legs as needed, adapting to different emergency scenarios. This device integrates multiple functions and is flexible in its form, serving both as a daily leash and a tool for rapid emergency response, thus improving the convenience of dog management and emergency rescue.
