Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and more particularly to a highly safe pet leash. Background Technology

[0002] Pets are becoming increasingly common in today's society. During the process of raising pets, owners and pets often go out together, such as when changing residences, taking walks, or training. Therefore, it is often necessary for owners to restrain or leash their pets, which has led to the development of pet leashes.

[0003] One end of the pet leash is held by the owner, and the other end is attached to the pet, connected by a leash. However, current pet leashes have certain safety hazards. For example, when riding an elevator, if the pet is inside the elevator and the owner is outside, the owner cannot loosen the connection buckle attached to the pet using the leash in their hand. This could lead to a serious accident when the elevator starts moving.

[0004] Therefore, improvements are needed to address the problems existing in the background technology. Summary of the Invention

[0032] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0033] Example 1: As Figures 1 to 11 As shown, this embodiment provides a highly safe pet leash, including a leash body 1, a leash 2, a connecting mechanism 3, and a connecting buckle 4. The connecting buckle 4 is used to attach to the pet. The leash body 1 is connected to the connecting mechanism 3 via the leash 2. The connecting buckle 4 is detachably connected to the connecting mechanism 3. The leash body 1 can drive the connecting mechanism 3 to disengage the connecting buckle 4 from the connecting mechanism 3 via the leash 2. A braking mechanism is provided on the leash body 1.

[0034] This embodiment provides a highly secure pet leash that improves safety and reduces the occurrence of accidents. For example, when riding an elevator with the pet inside and the owner outside, the owner can loosen the connecting buckle 4 attached to the pet using the leash body 1 in their hand. This prevents the necklace from tightening around the pet when the elevator starts, thus avoiding accidents. In other words, in an emergency, the user can loosen the connecting buckle 4 attached to the pet using the leash body 1, separating the pet from the leash 2 to prevent accidents and improve the safety of the product.

[0035] Furthermore, the leash 2 includes a flexible tube 201 and a pull line 202 disposed within the flexible tube 201. A traction strap 203 is disposed outside the flexible tube 201. The leash 2 provided in this embodiment has relatively higher reliability and smaller size, thereby making the size and structure of the leash body 1 more compact. In addition, the pull line 202 slides and stretches inside the flexible tube 201. When leading a pet, the traction strap 203 is subjected to force alone, or the traction strap 203 and the flexible tube 201 are subjected to force together, while the pull line 202 is not subjected to force.

[0036] Furthermore, the connecting mechanism 3 includes a housing 31, a locking ring 32, a slider 33, a pulley 34, and a connecting pin 35. The front end of the housing 31 is movably inserted into the rear end of the locking ring 32. The slider 33 is slidably disposed within the housing 31. The pulley 34 is disposed within the slider 33. One end of the pull wire 202 is connected to the pulley 34. A sliding groove 310 is provided on the housing 31. A first connecting hole 320 is provided on the locking ring 32 at a position corresponding to the sliding groove 310. The connecting pin 35 passes through the sliding groove 310, and one end of the connecting pin 35 is connected to the slider 33, while the other end is connected to the first connecting hole 320. Its structure is simple. By pulling the pull wire 202, the slider 33 is driven to slide backward, and the slider 33 drives the locking ring 32 to move backward through the connecting pin 35 on it.

[0037] In this embodiment, the device further includes a sleeve 36, a latch 37, and a steel ball 38. The sleeve 36 is disposed within the locking ring 32 and is connected to the housing 31. The latch 37 is disposed within the sleeve 36, and its front end is used to connect with the connecting buckle 4. A steel ball hole 360 ​​is provided near the front end of the sleeve 36. A steel ball groove 370 is provided on the latch 37 to cooperate with the steel ball hole 360. The steel ball 38 is located within the steel ball hole 360 ​​and the steel ball groove 370.

[0038] Furthermore, a first spring 391 is provided between the locking ring 32 and the sleeve 36, a push plate 301 is provided at the rear end of the latch 37, and a second spring 392 is provided between the push plate 301 and the housing 31.

[0039] In an emergency, pulling the cable 202 causes the slider 33 to slide backward. The slider 33, through the connecting pin 35, causes the locking ring 32 to move backward. After the locking ring 32 moves backward, the steel ball 38 has room to move upward. The push plate 301 is pushed forward under the action of the second spring 392, thereby pushing out the latch 37. The latch 37 disengages from the connecting mechanism 3. The connecting buckle 4 and the latch 37 disengage together, thus separating the pet from the leash 2 to avoid accidents and improve the safety of product use.

[0040] Conversely, when it is necessary to connect the connecting buckle 4 to the connecting mechanism 3, simply insert the rear end of the latch 37 into the sleeve 36, push the latch 37 backward and push the push plate 301 until the second spring 392 is reset, the steel ball 38 is embedded into the steel ball groove 370, and the locking ring 32 is pushed and reset by the first spring 391.

[0041] In this embodiment, the traction device body 1 includes a housing assembly 11, a ratchet 12, a pawl transmission assembly 13, and a knob 14. A spool 17 is provided inside the housing assembly 11, and the ratchet 12 is provided on the spool 17. One end of the traction belt 203 and the flexible tube 201 are fixed on the spool 17, and one end of the pull wire 202 is fixed on the ratchet 12. The ratchet 12 is used to pull the pull wire 202. The pull wire 202 reduces the force through the pulley 34 to drive the slider 33 to move backward. The slider 33 moves the locking ring 32 backward through the connecting pin 35. The locking buckle 37 and the connecting buckle 4 disengage from the connecting mechanism 3 under the pushing force of the push plate 301.

[0042] The pawl drive assembly 13 is disposed inside the ratchet 12, and the knob 14 is disposed on the housing assembly 11 and connected to the pawl drive assembly 13. The knob 14 can drive the ratchet 12 to rotate through the pawl drive assembly 13. The ratchet 12 is used to pull the pull cable 202 to disengage the latch 37 from the connecting mechanism 3.

[0043] Furthermore, the pawl drive assembly 13 includes a cover plate assembly 130, a pawl pusher plate 131, and a pawl 132. The pawl pusher plate 131 is disposed below the cover plate assembly 130. The inner end of the pawl 132 is connected to the pawl pusher plate 131. A plurality of spaced ratchet teeth 120 are provided on the inner circumferential surface of the ratchet 12. A drive shaft 1310 is disposed at the center of the pawl pusher plate 131. The upper end of the drive shaft 1310 passes through the cover plate assembly 130 and the outer casing assembly 11 and is connected to the knob 14. The knob 14 can be driven by the drive shaft 1310. The pawl push plate 131 is rotated, and during the rotation of the pawl push plate 131, the pawl 132 is pushed outward so that the outer end of the pawl 132 engages with the ratchet tooth 120. At this time, by rotating the knob 14, the drive shaft 1310, pawl push plate 131, pawl 132, ratchet tooth 120, and ratchet 12 are activated. The ratchet 12 pulls the pull cable 202, and the pull cable 202 reduces the force through the pulley 34 to drive the slider 33 to move backward. The slider 33 drives the locking ring 32 to move backward through the connecting pin 35. Under the action of the push plate 301, the locking buckle 37 and the connecting buckle 4 disengage from the connecting mechanism 3.

[0044] Furthermore, the cover plate assembly 130 includes an upper cover plate 1301 and a lower cover plate 1302 assembled together. A hollow connecting post 1303 is provided at the center of the upper cover plate 1301. A through hole 110 is provided on the outer shell assembly 11. The connecting post 1303 is connected to the through hole 110. A silicone ring 15 is provided between the connecting post 1303 and the through hole 110. The drive shaft 1310 extends outward through the connecting post 1303 and connects to the knob 14. Thus, under the compression force of the silicone ring 15, the upper cover plate 1301 and the outer shell assembly 11 remain stationary when the knob 14 has no force. When the knob 14 is turned, due to the compression force of the silicone ring 15, the pawl 132 will overcome the tension of the tension spring 16 and engage with the ratchet 12 first. The pawl drive assembly 13 rotates, driving the ratchet 12 to rotate, thereby pulling the pull cable 202.

[0045] A tension spring 16 is provided between the pawl push plate 131 and the cover plate assembly 130. The tension spring 16 can keep the pawl 132 in a retracted state. In an emergency, the knob 14 is turned so that the pawl 132 can overcome the tension of the tension spring 16 and extend outward to engage with the ratchet tooth 120.

[0046] In this embodiment, a limiting hole 1304 is provided on the cover plate assembly 130, and a limiting post 1311 is provided on the pawl push plate 131. The limiting post 1311 is inserted into the limiting hole 1304 to axially limit the pawl push plate 131 and prevent it from falling off.

[0047] The pawl 132 includes a main body 1320, which is arc-shaped and located between the upper cover plate 1301 and the lower cover plate 1302. An inner column 1321 is provided at the inner end of the main body 1320, and an outer column 1322 is provided at the outer end. Pawl teeth 1323 for engaging with the ratchet teeth 120 are provided on the outer surface. Sliding grooves 1305 are provided on the pawl push plate 131 and the upper cover plate 1301. A second connecting hole 1306 is provided near the outer edge of the lower cover plate 1302. The upper and lower ends of the inner column 1321 are slidably connected to the sliding grooves 1305 on the upper cover plate 1301 and the ratchet push plate 131, respectively. The upper and lower ends of the outer column 1322 are connected to the second connecting hole 1306 on the upper cover plate 1301 and the lower cover plate 1302, respectively. This makes the overall structure of the traction device body 1 more compact and reasonable, and improves the stability and stability of the traction device body 1 during operation.

[0048] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
