Description

Technical Field

[0001] This utility model relates to the field of pet leash technology, and more specifically, to a leash device for preventing pet leash tangling. Background Technology

[0002] A pet leash is a tool or pet supply generally used to lead a pet.

[0003] Nowadays, pet dogs are increasingly appearing in our lives. As a product used to restrain pet dogs, the constant running, jumping, spinning, and changing direction of movement of pet dogs can cause the leash to twist and tighten, or even become tangled in the leash. In addition, when a leash is used to restrain multiple pets, the leash is more likely to become tangled due to the pets' activities. Utility Model Content

[0004] To overcome the above shortcomings, this utility model first provides a locking assembly.

[0005] This utility model is implemented as follows: It includes a locking part and an anti-winding connecting part connected to the locking part. The locking part includes at least one lock, a locking mounting base, a locking mounting cover, and a locking fixing shaft with the same number of locks disposed on the locking mounting base. The lock is rotatably sleeved on the locking fixing shaft. The locking mounting base has a screw hole at its end. The locking mounting base and the locking mounting cover constitute the locking assembly housing.

[0006] The anti-winding connection includes a screw that connects to the screw hole of the locking mounting base and a bearing sleeved on the screw. The bearing is freely rotatable relative to the locking part and the screw. The screw includes a cylindrical part and an external threaded part. The screw passes through the inner hole of the bearing and the screw hole of the locking mounting base. The bearing is sleeved on the cylindrical part. The internal thread and external thread of the nut are fixed by rotation using a tool.

[0007] The latch is one or two, and each latch includes an annular hole at one end, which can be fitted onto the latch fixing shaft. The latch is equipped with a latch switch, with a smaller opening at the top and a larger opening at the outside. The traction rope passes through the latch switch and is fastened to the latch or secured with a double ring. The latch is a common existing product.

[0008] The locking shaft is hollow, and the locking cover has a positioning post that can be inserted into the hollow position of the locking shaft. After the locking shaft and the positioning post in the locking cover are positioned and inserted, the locking base and the locking cover are fixed. The locking can rotate freely around the locking shaft, providing the locking can move freely when the pet moves the leash left and right.

[0009] When there is only one latch, the latch mounting base and latch mounting cover are provided with limiting grooves for the latch to slide left and right. These limiting grooves are located in front of the latch mounting base and latch mounting cover. In this case, the limiting grooves for the latch to slide left and right can occupy at least half of the outer circumference of the latch mounting housing of the latch assembly, providing a large range of motion.

[0010] When there are two latches, the latch mounting base and latch mounting cover are respectively provided with limiting grooves on both sides for the latches to slide left and right. The two limiting grooves are separated by a middle space, and the two latches only slide within the limiting grooves on both sides. At this time, the latches on both sides can only move freely on their respective sides, and the middle space prevents the two latches from contacting and colliding.

[0011] The locking mounting base and locking mounting cover are fixedly connected by adhesive or snap fasteners.

[0012] Furthermore, this utility model also provides an anti-tangling traction rope device, which includes the aforementioned locking assembly and a handle and lever connected to the locking assembly. The handle includes a handle base and a handle cover. One end of the handle base and handle cover is provided with a groove for embedding a bearing. After the handle base and handle cover are installed, they are connected to the locking assembly through the embedded bearing. The bearing can rotate freely in the groove. The combined locking assembly and handle form an anti-tangling traction rope device. The handle is connected to the handle through the bearing of the locking assembly, and the front locking assembly can rotate freely when the handle is stationary. Meanwhile, in double-lock mode, the two sets of leashes will not become tangled due to the pets changing positions or running around. In single-lock mode, the leashes will not be tightened and thus not get tangled in the leash.

[0013] One end of the handle is set as a ring-shaped part, and a handle fixing shaft is provided inside the bottom shell of the grip. After the ring-shaped part of the handle is fitted onto the handle fixing shaft, it extends out of the grip to form a ring-shaped handle outside the grip, thus forming an integrated handle and grip.

[0014] The handle fixing shaft has an internal opening, and the grip cover is provided with a positioning post that can be inserted into the internal opening, so as to realize the positioning and installation of the grip bottom shell and the grip cover.

[0015] The upper edge of the grip bottom shell is provided with a positioning groove, and the lower edge of the grip cover is provided with a second ultrasonic welding line at intervals. After the grip bottom shell and the grip cover are closed, the second ultrasonic welding line is welded into the positioning groove using an ultrasonic welding machine.

[0016] The positioning of the positioning pin and / or the ultrasonic welding line ensures the fixation of the grip and handle, and also ensures the stability of the bearing within the grip, preventing the grip from separating or being damaged.

[0017] The beneficial effects of this utility model are: The locking mechanism provides ample room for movement when the pet is active. When used with the handle, it prevents the handle from violently following the leash when the pet runs left or right, reducing hand pressure and swaying. Furthermore, when the locking mechanism, handle, and pull are assembled to form a new leash accessory, the locking mechanism can rotate freely relative to these components. Under traction, the locking mechanism automatically rotates in the direction of entanglement, completely preventing leash tangling, especially when a double locking mechanism is used.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0021] Please see Figures 1-4 This utility model provides a locking assembly 1, which includes a locking part 1000 and an anti-winding connecting part 1100 connected to the locking part 1000. The locking part 1000 includes at least one locking buckle 700, a locking buckle mounting base 500, a locking buckle mounting cover 800, and a locking buckle fixing shaft 520 arranged on the locking buckle mounting base 500 in the same number as the locking buckles. The locking buckle 700 is rotatably sleeved on the locking buckle fixing shaft 520. The locking buckle mounting base 500 has a screw hole 510 at its end. The locking buckle mounting base 500 and the locking buckle mounting cover 800 constitute a locking buckle shell.

[0022] like Figure 3 As shown, the anti-winding connecting part 1100 includes a screw 300 that is screwed into the screw hole 510 of the locking mounting base 500, and a bearing 400 sleeved on the screw 300. The bearing 400 is freely rotatable relative to the locking part 1000 and the screw 300. The screw 300 includes a cylindrical part 310 and an external thread part 320. The screw 300 passes through the inner hole of the bearing 400 and the screw hole of the locking mounting base. The bearing 400 includes an inner hole 410 and an outer circle 420. The bearing is sleeved on the cylindrical part 310 of the screw. The internal thread of the nut 300 and the external thread of the nut are fixed by rotation using a tool, thereby achieving a fixed assembly of the screw 300, the bearing 400, and the locking mounting base 500.

[0023] In this embodiment, as Figure 3 As shown, the locking fixing shaft 520 is hollow, and the locking mounting cover 800 is provided with a positioning post 820 that can be embedded in the hollow position of the locking fixing shaft. After the locking fixing shaft 520 and the positioning post 820 in the locking mounting cover 800 are positioned and embedded, the locking mounting base shell 500 and the locking mounting cover 800 are fixed. The locking buckle 700 can rotate freely around the locking fixing shaft 520, providing the locking buckle with a certain amount of free movement when the pet moves the leash left and right during pet leash movement.

[0024] Furthermore, in this embodiment, there are one or two latches 700. Each latch 700 includes an annular hole 710 at its end, which can be fitted onto the latch fixing shaft 520. The latch 700 is equipped with a latch switch, with a smaller opening at the top and a larger opening at the outside. The traction rope passes through the latch switch and is fastened to the latch or secured by a loop (double ring). The latch is a common existing product.

[0025] In this embodiment, if there is only one latch 700, the latch mounting base 500 and the latch mounting cover 800 are provided with a limiting groove 270 for the latch to slide left and right. The limiting groove 270 is located in front of the latch mounting base 500 and the latch mounting cover 800. In this case, the limiting groove 270 for the latch to slide left and right can occupy at least half of the outer periphery of the latch mounting housing of the latch assembly, providing a large range of motion.

[0026] In this embodiment, when there are two latches 700, the latch mounting base 500 and the latch mounting cover 800 are respectively provided with limiting grooves 270 for left and right sliding of the latches on both sides. The two limiting grooves 270 are spaced apart, and the two latches 700 slide only within the limiting grooves 270 on both sides. At this time, the latches on both sides can only move freely on their respective sides, and the spaced-apart arrangement prevents the two latches from contacting and colliding.

[0027] In this embodiment, as Figure 3 As shown, the locking fixing shaft 520 is hollow, with a positioning hole 540 inside. The locking mounting cover 800 is also provided with a first ultrasonic welding line 810. The outer edge of the locking mounting base 500 is provided with a positioning groove 530 that can be embedded in the first ultrasonic welding line 810. When the positioning post 820 of the locking mounting cover 800 is pressed into the positioning hole 540 of the locking mounting base 500, the first ultrasonic welding line 810 on the edge of the hook cover 800 is melted and welded into the positioning groove 530 of the locking mounting base 500 using an ultrasonic welding machine.

[0028] In addition, the locking mounting base 500 and the locking mounting cover 800 can also be fixedly connected by adhesive or snap fasteners. Example 2

[0029] Furthermore, such as Figures 5-10As shown, this utility model also provides an anti-tangling leash device, which includes the locking assembly 1 described in Embodiment 1, and a handle 200 and a pull handle 100 connected to the locking assembly. The handle 200 includes a handle base shell 250 and a handle cover 160. One end of the handle base shell 250 and the handle cover 260 is provided with a groove 240 that can be embedded in a bearing 400. After the handle base shell 250 and the handle cover 260 are installed, they are connected to the locking assembly 1 through the embedded bearing 240. The bearing 400 can rotate freely in the groove, thereby realizing the free rotation of the locking assembly 1 relative to the handle and preventing the pet leash from getting tangled. Specifically, the combined locking assembly 1 and handle form an anti-tangling traction rope device. The handle is connected to the handle 200 through the bearing 400 of the locking assembly 1. The front locking assembly 1 can rotate freely when the handle is stationary.

[0030] In particular, in the double-locking mode, that is, when the locking assembly 1 is equipped with two locks, two pets can be pulled by a leash. In this case, the two sets of leashes of the freely rotating locking assembly 1 will not become tangled due to the pets changing positions or running around.

[0031] Meanwhile, in single-lock mode, that is, when the locking assembly 1 is equipped with 1 lock, the traction rope will not be tightened and thus not get tangled around the traction device.

[0032] In this embodiment, the locking assembly 1, which can rotate freely relative to the handle 200, together with the locking mounting base 500 and the locking mounting cover 800, forms a limiting groove 270 that can maximize the range of motion of the locking 700 while ensuring that the traction rope does not get tangled and preventing the traction rope from self-tightening.

[0033] In this embodiment, one end of the handle 100 is configured as an annular portion 110, and a handle fixing shaft 210 is provided inside the grip bottom shell 250. After the annular portion 110 of the handle 100 is fitted onto the handle fixing shaft 210, it extends out of the grip, forming an annular handle outside the grip, thus forming an integral handle 100 and grip 200.

[0034] The handle fixing shaft 210 has an internal opening 220, and the grip cover 260 is provided with a positioning post 910 that can be embedded in the internal opening, so as to realize the positioning of the grip bottom shell 250 and the grip cover 260.

[0035] The upper edge of the grip bottom shell 250 is provided with a positioning groove 230, and the lower edge of the grip cover 260 is provided with a second ultrasonic welding line 920 at intervals. After the grip bottom shell 250 and the grip cover 260 are closed, the second ultrasonic welding line 920 is welded into the positioning groove 230 using an ultrasonic welding machine 920, thereby realizing the fixed connection between the grip bottom shell 250 and the grip cover 260.

[0036] Alternatively, in this embodiment, the grip base shell 250 and the grip cover 260 can be fixedly connected by means of snaps or bolts.

[0037] The traction rope device described in this embodiment can achieve multiple functions: 1. A single latch 700 can rotate 90° around the cylinder 520 of the hook bottom 500, such as... Figure 8 As shown.

[0038] 2. The hook assembly 1000 can rotate 360° around the inner hole 410 of the bearing 400, such as... Figure 9 As shown.

[0039] 3. Combining the functions of 1 and 2 above, when the two locking buckles 700 are about to get tangled due to the pet's irregular movements, the hook assembly 1000 will automatically rotate in the direction of tangling under the action of traction, thereby achieving the purpose of preventing the leash from getting tangled.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
