Description

Technical Field

[0001] This utility model relates to the field of dog leashes, specifically to a dog leash leash with a quick-locking function. Background Technology

[0002] With the continuous increase in the number of pet owners, dog leashes (the specific structure of a dog leash can be found in CN201922033127.4, a dog leash with locking function) are becoming an essential tool for pets, and their frequency of use and importance are increasingly prominent. However, in actual use, dog walkers often encounter many inconveniences. For example, when entering places where pets are not allowed, such as shopping malls, hospitals, and libraries, or in situations where pets need to be temporarily restrained, such as resting on park benches or shopping on the street, the lack of convenient restraint devices means that the dog leash can only be wrapped around railings, table and chair legs, etc. This method is not only cumbersome to operate, but also the restraint effect is unstable, posing a safety hazard of the pet breaking free. Utility Model Content

[0003] In view of the above, the purpose of this utility model is to address the problems of the prior art by providing a dog leash with a quick fixing function.

[0004] This solution provides a dog leash with a quick-locking function, comprising a main handle and a reel. The reel contains a rope, and the main handle includes a fixed part and a movable part. A hinge shaft connects the fixed part and the movable part to form a freely opening and closing ring structure. A torsion spring is sleeved outside the hinge shaft. The torsion spring acts on the movable part and the fixed part, and under normal conditions, the torsion spring provides a closing force to keep the ring structure closed.

[0005] Furthermore, the main grip is also provided with a press-type unlocking mechanism, which under normal conditions creates mechanical interference with the rotation of the movable part.

[0006] Furthermore, the hinge shaft is integrally formed inside the fixed part, and the movable part is provided with a bushing that matches the hinge shaft. The bushing is fitted onto the hinge shaft, and a positioning groove is provided inside the fixed part. A torsion spring is fitted onto the hinge shaft, with one end of the torsion spring locked in the positioning groove and the other end locked at the engagement position between the bushing and the movable part. When the movable part is opened, the torsion spring is compressed and stores elastic potential energy. When the external force disappears, the torsion spring releases the elastic potential energy, pushing the movable part to close automatically.

[0007] Furthermore, the press-type unlocking mechanism includes a button, a spring, an upper limit groove, a lower limit groove, and an outer ridge; the bushing has an internally formed mounting groove into which the button is inserted; the spring is positioned between the bottom of the button and the bottom of the mounting groove, and under the action of the spring, the button extends out of the fixed part; a hole is provided on the fixed part for the button to pass through, and the upper limit groove is provided on the inner edge of the hole; the outer ridge is provided on the outer wall of the button, and the lower limit groove is provided on the bushing; under normal conditions, the outer ridge of the button is pushed outward under the force of the spring, causing the button to extend out of the fixed part, while simultaneously causing the outer ridge to be stuck in both the upper and lower limit grooves, preventing the bushing from rotating; when it is necessary to open the main handle, pressing the button causes the button to move inward, the outer ridge leaves the upper limit groove, and the limiting constraint on the bushing is released.

[0008] Compared with the prior art, this application has the following advantages:

[0009] 1. Solving the problem of temporary fixation: In view of the problems of existing dog leashes being cumbersome to operate, having unstable fixation effect, and posing safety hazards when temporarily fixing, the main handle of this application adopts a split hinge structure. By opening the movable part, it can be easily slipped onto the object to achieve quick fixation, solving the inconvenience in actual use.

[0010] 2. Primary locking ensures basic safety: The main handle relies on the closing force of the torsion spring to achieve primary locking. The elastic potential energy of the torsion spring keeps the moving part always tending to close towards the fixed part, ensuring that the dog leash will not open accidentally during normal holding and leashing, meeting the basic safety needs of daily dog ​​walking, providing a stable and reliable holding experience, and also ensuring normal locking when fixed.

[0011] 3. Dual limit design enhances safety: The design features a press-type unlocking mechanism that locks the moving part again on top of the torsion spring. The dual limit design allows the main handle to be opened only when the button is pressed first and the torsion spring force is overcome. This effectively avoids the risk of misoperation and accidental unlocking, and prevents the main handle from opening due to external impacts, violent pulling by pets, etc. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1 to 6 The dog leash shown has a quick-locking function, and its core components are a main handle and a reel 3. The main handle adopts a split hinge structure, consisting of a fixed part 1 and a movable part 2 connected by a hinge shaft 1a, forming a freely opening and closing ring structure. The reel 3 contains a rope, and the reel 3 and the fixed part 1 are integrally formed. A torsion spring 4 is sleeved on the outside of the hinge shaft 1a. The torsion spring 4 provides a closing torque to the movable part 2, keeping the main handle closed in the normal state and ensuring the normal gripping function of the dog leash.

[0020] When dog walkers encounter situations where they need to temporarily secure their dogs with a leash, they can simply open the activity section 2 to easily attach the leash to objects such as shopping mall railings, park bench handrails, and street lampposts for quick and easy fixation.

[0021] It should be noted that under normal use, the main handle relies on the closing force of the torsion spring 4 to achieve primary locking. The elastic potential energy of the torsion spring 4 ensures that the moving part 2 always tends to close towards the fixed part 1, guaranteeing that the dog leash will not accidentally open during normal gripping and leash operation. This basic locking method meets the basic safety needs during daily dog ​​walking, providing pet owners with a stable and reliable gripping experience. It also ensures that the dog leash remains properly locked when fixed to an object.

[0022] To further enhance the security of the dog leash and prevent the main handle from opening due to external impacts, violent pulling by the pet, or other unexpected situations, this technical solution features a press-type unlocking mechanism that further locks the moving part 2 based on the torsion spring 4. This dual-limit design ensures that the main handle can only be opened if the button 5 is pressed first, and then the spring force of the torsion spring 4 is overcome, effectively avoiding the risk of misoperation and accidental unlocking.

[0023] Specifically, the hinge shaft 1a of this application is fixed inside the fixed part 1 using an integral molding process, providing a stable support shaft for the rotation of the movable part 2. The movable part 2 is provided with a bushing 2a that matches the hinge shaft 1a. The bushing 2a is fitted onto the hinge shaft 1a to ensure that the movable part 2 can rotate flexibly. A positioning groove 1b is provided inside the fixed part 1. A torsion spring 4 is fitted onto the hinge shaft 1a, with one end firmly locked in the positioning groove 1b and the other end locked at the engagement position between the bushing 2a and the movable part 2. When the movable part 2 is opened, the torsion spring 4 is compressed and stores elastic potential energy; when the external force disappears, the torsion spring 4 releases the elastic potential energy, pushing the movable part 2 to close automatically, realizing a first-level locking function.

[0024] The push-button unlocking mechanism mainly consists of a button 5, a spring 6, an upper limit groove 1c, a lower limit groove 2a1, and an outer ridge 5a. An installation groove 2a2 is formed inside the bushing 2a, into which the button 5 is inserted. The spring 6 is positioned between the bottom of the button 5 and the bottom of the installation groove 2a2. Under the action of the spring 6, part of the button 5 extends out of the fixed part 1, facilitating external operation. A hole is provided on the fixed part 1 for the button 5 to pass through, with an upper limit groove 1c along the inner edge of the hole. A protruding outer ridge 5a is provided on the outer wall of the button 5, and a lower limit groove 2a1 is provided on the bushing 2a. Under normal conditions, the outer ridge 5a of the button 5 is pushed outward under the force of the spring 6, causing part of the button 5 to extend out of the fixed part 1. Simultaneously, the outer ridge 5a is locked in both the upper limit groove 1c and the lower limit groove 2a1, effectively preventing the bushing 2a from rotating, thus achieving a two-stage locking of the movable part 2. When it is necessary to open the main grip, the user needs to press the button 5 firmly to move the button 5 inward, so that the outer edge 5a leaves the upper limit groove 1c and releases the limiting constraint on the bushing 2a. At this time, the user can overcome the elastic force of the torsion spring 4 to open the movable part 2 and complete the unlocking operation.

[0025] It should be noted that, to facilitate the installation of various components, the main handle and the drum 3 adopt a structural design consisting of two halves of the shell. This split design allows for easy installation and adjustment of components such as the torsion spring 4 and the push-to-unlock mechanism, which not only improves production efficiency but also reduces assembly difficulty and production costs, while also facilitating later maintenance.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
