Description

Technical Field

[0001] The present application relates to the technical field of dog leashes, and in particular to a palm-type dog leash. Background Art

[0002] Some dog leashes on the market have large shells, which are not convenient for carrying and using. Especially for small dogs or when traveling, large leashes may take up too much space in the bag, causing inconvenience to the user. At the same time, the pulling effect of such dog leashes is not ideal, and they cannot be flexibly retracted and released according to the different walking speeds and strengths of the dogs, affecting the owner's effective control over the dog's movements. The design fails to fully consider the function of preventing pets from rushing forward. When the dog suddenly rushes forward or is stimulated by external factors, the constant speed of the existing dog leashes cannot provide appropriate resistance or buffering. Utility Model Content

[0003] The device provides a palm-type dog leash, and the specific implementation is as follows:

[0004] A palm-type dog leash, comprising:

[0005] A housing and a dog leash wound inside the housing, a reset structure is provided between the inner end of the dog leash and the housing, an opening is provided on the housing for leading out the dog leash, and a lock is provided at the opening for limiting the extension length of the dog leash;

[0006] The rope-releasing drum for winding the dog rope is rotated in the housing, and a damping structure acting on the rope-releasing drum is provided in the housing, so that the speed of releasing the rope when walking the pet is slowed down by the damping structure;

[0007] A hand strap is arranged outside the housing, the size of the housing is adapted to the palm of the dog walker, and the hand strap is arranged at the wrist position to prevent the housing from falling off freely;

[0008] A detachable cover is installed on one side of the shell, and an annular cavity is formed between the cover and the shell; a fixed shaft is axially arranged at the center of the annular cavity, and the central through hole of the rope drum is sleeved on the outside of the fixed shaft, and the two are connected by a coil spring.

[0009] Based on the above technical solutions, a miniaturized shell design is adopted to address the problems of existing dog leashes, such as being too large and inconvenient to operate. Its compact size allows users to hold it directly in the palm of their hand, greatly improving the portability and maneuverability of the dog leash. Whether it is quickly adjusting the length of the dog leash or flexibly operating it in a small space, it can be done with ease. In addition, in order to solve the hidden danger of the dog leash accidentally falling off, the palm-type dog leash is also equipped with a wrist restraint design. The dog leash is tightly connected to the user's wrist, and even if an emergency occurs during dog walking, such as the dog suddenly rushing or other strenuous exercise, the dog leash can be effectively prevented from accidentally slipping from the hand, ensuring effective control of the dog and greatly improving the safety of the dog walking process.

[0010] Optionally, the damping structure can be arranged in the following three forms:

[0011] Firstly, the damping structure is specifically a needle roller clutch meshed with the rope-releasing drum, and the fixed end of the needle roller clutch is connected to the cover plate.

[0012] Preferably, an outer gear ring is provided on the side of the rope release drum, and the outer gear ring is engaged with the driven shaft of the transmission end of the needle clutch.

[0013] Preferably, the needle clutch is composed of a one-way bearing and a brake disc, and the one-way bearing includes an active ring and a passive ring which are sleeved together; the active ring is coaxially connected to the driven shaft, and the passive ring is connected to the brake disc.

[0014] Preferably, the active ring is provided with a plurality of oblique protrusions equidistantly along its circumference, the oblique surfaces of which are in contact with needle rollers, and a spring member is provided between the needle rollers and the vertical surfaces of the oblique protrusions.

[0015] Preferably, a slot is provided outside the passive ring, and the brake disc is connected to the passive ring through the slot.

[0016] Based on the above technical solution, the needle roller clutch is composed of needle rollers, a retaining frame, inner and outer rings. The needle roller clutch is mainly used to transmit torque and allows free rotation in the direction of rope collection, while it is engaged with the brake disc in the direction of rope release. The brake disc is a high-damping rotating part arranged on the cover plate. When the active ring and the passive ring drive the output end of the brake disc to rotate synchronously, a unidirectional resistance is generated on the rope release drum through the meshing effect.

[0017] Secondly, the damping structure is specifically composed of two groups of damping plates, one of which is arranged at the side of the rope drum along the circumference, and the other is arranged equidistantly along the circumference of the cover plate; the two groups of damping plates have the same center and the same circumference size, and friction resistance is generated by abutment between the two to achieve the damping effect of the dog leash.

[0018] Based on the above technical solutions, the rope release drum is linked with the dog leash. When the dog leash is pulled out or retracted, the rope release drum will rotate accordingly. Multiple groups of damping plates are designed inside, and these damping plates will move synchronously during the rotation of the rope release drum. When the dog leash is pulled out or retracted quickly, the rope release drum drives the damping plate to rotate. If the two groups of damping plates overlap each other due to rotation, a certain resistance will be immediately generated. This resistance acts on the process of releasing and retracting the dog leash, which can effectively slow down the movement speed of the dog leash, thereby achieving a damping effect on the action of releasing and retracting the dog leash. The tension of the dog leash is automatically adjusted according to the dog's movement state. Especially when the dog suddenly bursts or brakes, the damping effect can prevent the dog leash from being instantly tightened or overly relaxed, thereby effectively protecting the dog and the owner, and also providing the dog with a more stable and comfortable range of activities, which is conducive to the benign cultivation of the dog's behavioral habits. Third, the damping structure is specifically two groups of magnetic damping plates. The two groups of damping plates generate magnetic force through the installation gap to achieve the damping effect of the dog leash.

[0019] Based on the above technical solutions, in order to further improve the accuracy and service life of the damping effect, magnetic suction is used to replace the contact friction damping design; the inside of the dog leash retraction and release tube no longer relies on two sets of damping plates to generate friction resistance through physical contact, but magnetic materials are used instead to control the retraction and release speed of the dog leash through the principle of magnetic attraction and repulsion; when the dog leash is pulled or reeled, the built-in magnetic element will generate suction or repulsion in the dynamic process. The effect of this force is equivalent to a controllable resistance. When the dog leash is pulled out or retracted quickly, the tension and relaxation speed of the dog leash can be automatically adjusted through magnetic suction, so as to achieve smooth control of the dog leash movement, prevent the pet from suddenly rushing out when the dog leash is pulled out, and prevent the rapid retraction of the dog leash from scratching people's hands.

[0020] Preferably, the shell body is in a circular structure as a whole, and a positioning column is embedded in the exterior of the shell body, and the positioning column is connected to the rope-releasing drum.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. The utility model miniaturizes the housing into a palm-held control, and the hand rope on the wrist prevents the palm-type dog rope from accidentally falling off;

[0023] 2. The utility model has a simple structure and slows down the pulling and drawing speed of the dog leash through the friction damping or magnetic damping effect between the damping sheets, effectively preventing the pet from responding in time after the sudden rush and the sudden rush of the leash when the dog leash is rolled up;

[0024] 3. The utility model provides a one-way damping effect by setting a needle clutch, and the pulling and pulling speeds are differentiated. When the dog leash is pulled out, it produces a damping and deceleration effect with the brake disc, and when the dog leash is retracted, the speed is fast and the response is timely.
