Description

Technical Field

[0001] The invention relates to the technical field of pet chains, and in particular to an emergency release safety buckle pet chain. Background Art

[0002] Traditional pet chains mostly use simple ropes or metal chains to connect pet collars. Although they can meet basic pet walking needs, in emergency situations, such as when the owner enters the elevator while the pet is outside the elevator and the elevator door is closed and starts to rise, these traditional pet chains often lack an effective quick release mechanism, which not only makes it difficult to ensure the safety of the pet, but also may pose a safety hazard to people around them. Therefore, there is an urgent need for a pet chain that can effectively control the pet's range of activities and quickly release the pet in an emergency to ensure the safety of the pet and surrounding people.

[0003] However, ordinary pet chains usually have some problems in daily use. With the development of science and technology, technicians in related fields have also made a lot of optimizations on pet chains to solve some problems that different consumer groups are concerned about. In order to make a more accurate comparison, a Chinese patent with publication number CN111713424A discloses a pet chain; it includes a chain made of webbing and a neck cover formed by the webbing, a buffer box with a buffer function is provided at the joint of the neck cover, a buffer assembly is provided in the buffer box, a first opening and a second opening are provided on the buffer box, one end of the neck cover is fixedly connected to the buffer box, and the other end passes through the first opening to be connected to the buffer assembly, the chain passes through the second opening to be connected to the buffer assembly, and a buffer belt is also provided on the chain.

[0004] When the pet is in use, the buffer box provides a buffering effect on the chain to prevent the pulling force on the person from suddenly increasing and causing harm to the person when the pet suddenly rushes forward.

[0005] However, the pet chain of the above-mentioned prior art still has some shortcomings in actual use: 1. When the pet encounters danger, the restraint of the chain may make the pet unable to quickly escape from the dangerous area, so the owner needs to release the restraint of the pet to enable the pet to escape, but the above-mentioned prior art cannot quickly release the restraint of the pet, thereby failing to ensure the safety of the pet.

[0006] 2. When the pet is in danger and the owner is not around the pet, it is necessary to allow the pet to break free from the pet chain by itself so that the pet can avoid danger. However, the above-mentioned prior art cannot enable the pet to automatically break free from the restraints and leave the dangerous area when encountering danger, and its applicability is relatively small.

[0007] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing pet chains. Summary of the invention

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 7 Embodiments of the present invention are described in detail.

[0033] The embodiment of the present application discloses an emergency release safety buckle pet chain. It should be noted that the emergency release safety buckle pet chain of the present application is mainly used when the pet is in danger. In terms of technical effect, it can manually and quickly release the pet by squeezing the safety handle 2; especially when the pet is in danger and pulls the leash 3 hard, the pet can easily break free from the matching rod 126, and the pet can automatically break free, so that the pet can quickly escape from the dangerous area after breaking free to avoid harm; further, the emergency release safety buckle pet chain can also prevent the owner from accidentally touching the pinching down rod 54 to release the pet when the pet rushes out.

[0034] Embodiment 1:

[0035] Reference Figure 1 and Figure 2As shown, an emergency release safety buckle pet chain includes a quick-release lock buckle 1 and a safety handle 2, the quick-release lock buckle 1 and the safety handle 2 are connected by a leash 3, a receiving groove 4 is opened in the quick-release lock buckle 1, a self-locking mechanism 12 is installed in the receiving groove 4, and an unlocking mechanism 21 connected to the self-locking mechanism 12 is installed in the safety handle 2; the self-locking mechanism 12 includes two opening grooves 121 opened on the side of the receiving groove 4 away from the safety handle 2, the two opening grooves 121 are symmetrically distributed up and down, the opening grooves 121 are connected to the receiving groove 4, the inner wall of the receiving groove 4 is rotatably connected to two rotating shafts 122, the outer walls of the two rotating shafts 122 are both sleeved with locking rods 123, and the ends of the two locking rods 123 away from the rotating shafts 122 respectively pass through the two opening grooves 121.

[0036] During the specific implementation process, first grasp the quick-release lock buckle 1, and control the locking rod 123 on the quick-release lock buckle 1 to rotate in opposite directions along the rotating shaft 122 and open through the self-locking mechanism 12, and then buckle it on the collar of the pet. When the owner takes the pet out, the owner can lead the pet through the safety handle 2 and the leash 3, thereby preventing the pet from running around and getting lost or getting into danger; when an emergency occurs, such as when the owner or the pet is injured, the pet needs to be released so that the pet or the owner can escape from the crisis. At this time, the owner controls the self-locking mechanism 12 through the unlocking mechanism 21 on the safety handle 2 to drive the two locking rods 123 to rotate in opposite directions along the rotating shaft 122 so as to quickly open, so that the pet loses control of the locking rod 123 and quickly avoids danger, thereby improving the safety and applicability of the pet chain.

[0037] In addition, in an emergency, if the owner is not with the pet and the pet chain is tied to a fixed pile, the pet can break free by pulling the quick-release buckle 1. When the pet feels extremely frightened or threatened, it will usually instinctively pull the leash 3 hard to try to escape from the dangerous area. When the leash 3 is subjected to a tension exceeding a preset threshold, the self-locking mechanism 12 in the quick-release buckle 1 will be triggered to control the two locking rods 123 to rotate oppositely on the rotating shaft 122, and the locking rod 123 slides out of the slot 121, thereby releasing the lock on the collar. Once the locking rod 123 slides out, the collar is no longer constrained by the locking rod 123, and the pet can break free quickly. After breaking free, the pet can quickly escape from the dangerous area to avoid injury, thereby providing extremely high safety and reliability for the pet through manual and automatic dual unlocking.

[0038] Reference Figure 2 and Figure 3As shown, in order to be able to restrain pets when going out and prevent them from running around and causing danger or accidents; based on this, in this embodiment, an unlocking mechanism 21 is provided, and two locking rods 123 are symmetrically distributed up and down, and the locking rods 123 are divided into a locking rod 124, a limiting rod 125 and a matching rod 126. The locking rod 124 is close to the safety handle 2 and gradually tilts toward the side away from the center of the accommodating groove 4, and the limiting rod 125 is away from the safety handle 2 and gradually tilts toward the side away from the center of the accommodating groove 4, and the limiting rod 125 passes through the slot 121, and the rotating shaft 122 is located at the connection between the limiting rod 125 and the locking rod 124, and the limiting rod 125 is connected to the matching rod 126 at the end away from the safety handle 2, and the opposite sides of the two matching rods 126 are clamped with each other.

[0039] Further, in the present embodiment, through grooves 127 are provided on the upper and lower side walls of the accommodating groove 4, and a pressing block 128 is slidably connected in the through groove 127. A clamping groove 129 is provided on the opposite sides of the two pressing blocks 128. The end of the locking rod 124 away from the limiting rod 125 is located in the clamping groove 129, and the two locking rods 124 are connected to the accommodating groove 4 with an extrusion spring 130 on the opposite sides. The unlocking mechanism 21 also includes a support frame 131 installed on the side of the accommodating groove 4 close to the safety handle 2, and a top spring 132 is installed on the side of the support frame 131 away from the safety handle 2. The top spring 132 is connected to a clamping block 133 located between the two locking rods 124 on the side away from the support frame 131. The clamping block 133 is trapezoidal, and the inclined surfaces on both sides of the clamping block 133 are parallel to the locking rod 124.

[0040] It should be noted that the lengths of the upper and lower ends of the pressing block 128 are greater than the length of the through-groove 127, so as to prevent the pressing block 128 from being completely retracted into the accommodating groove 4 or sliding out of the through-groove 127 due to excessive force; the extrusion spring 130 always applies an elastic force to the locking rod 124 toward the middle of the accommodating groove 4, so that after the locking rod 124 loses the support of the clamping block 133, the extrusion spring 130 drives the locking rod 124 to rotate toward the middle of the accommodating groove 4 and drives the matching rod 126 to open; the extrusion spring 130 always applies an elastic force to the clamping block 133 toward the side away from the traction rope 3, so that the clamping block 133 always supports the two locking rods 124, ensuring that the locking rod 124 cannot rotate in the initial state.

[0041] In the specific implementation process, the pressing blocks 128 on both sides of the quick-release buckle 1 are pinched, and the pressing blocks 128 slide along the through grooves 127 into the accommodating groove 4 and squeeze the locking rod 124, and the locking rod 124 rotates along the rotating shaft 122 toward the middle of the accommodating groove 4, and the squeezing spring 130 adaptively expands and contracts. During the rotation of the two locking rods 124, the clamping block 133 is squeezed, so that the clamping block 133 moves toward the side close to the traction rope 3 under the squeezing action of the locking rod 124, and the top spring 132 adaptively contracts, and the two locking rods 124 slide along the clamping groove 129; at the same time, the locking rod 124 drives the limiting rod 125 to rotate along the rotating shaft 122 away from the middle of the accommodating groove 4 and The matching rod 126 is driven to move synchronously in a circumferential direction, so that the two matching rods 126 are opened. After the two matching rods 126 are inserted into the collar, the pressing block 128 is released, and the top spring 132 rebounds and drives the clamping block 133 to move away from the leash 3. The clamping block 133 squeezes the two locking rods 124, so that the two locking rods 124 rotate toward the side away from the clamping block 133, and drives the limit rod 125 and the two matching rods 126 to move towards each other and clamp, thereby realizing the restraint of the pet. The mutual clamping of the two matching rods 126 can prevent the pet from struggling to break free for a long time, causing a gap between the two matching rods 126, affecting the restraint of the pet, and greatly improving the quality of the pet chain.

[0042] Reference Figure 4 and Figure 5 As shown, in order to be able to quickly release the pet in an emergency; based on this, in this embodiment, two penetration holes 211 are opened in the middle of the leash 3, and a pull rope 212 located in the penetration hole 211 is connected between the clamping block 133 and the unlocking mechanism 21, and a plurality of telescopic rods 213 are connected between the clamping block 133 and the accommodating groove 4; an unlocking groove 214 is opened in the safety handle 2, and the penetration hole 211 is connected to the unlocking groove 214, and a plurality of protrusions 215 are installed on the side of the unlocking groove 214 away from the leash 3, and the pull rope 212 passes through the unlocking groove 214 and then bypasses the plurality of protrusions 215, and the inside of the safety handle 2 is away from the leash 3 Two groups of sliding grooves 216 connected to the unlocking grooves 214 are provided on one side, and each group of sliding grooves 216 has two sliding grooves 216 that are symmetrically distributed up and down. A connecting rod 217 is slidably connected in the sliding grooves 216. The connecting rod 217 in each group of sliding grooves 216 is commonly connected to a pressing rod 218 on the side away from the protrusion 215. The two connecting rods 217 are installed with an extrusion block 219 on the side close to the protrusion 215. The extrusion block 219 is provided with a plurality of grooves 220 that cooperate with the protrusion 215 on the side close to the protrusion 215; a return spring 221 is connected between the side of the pressing rod 218 close to the protrusion 215 and the inner wall of the safety handle 2.

[0043] It should be noted that, due to the limitation of the telescopic rod 213 , the clamping block 133 can only slide along the telescopic direction of the telescopic rod 213 .

[0044] During the specific implementation process, when the owner is holding the pet and an emergency occurs, the owner can pinch the two pressing rods 218 on the inner wall of the safety handle 2, so that the two pressing rods 218 drive the four connecting rods 217 to slide synchronously along the sliding groove 216 into the unlocking groove 214, and the reset spring 221 shrinks adaptively. The two connecting rods 217 on each pressing rod 218 respectively drive the two extrusion blocks 219 to approach the protrusion 215 and squeeze the cable 212, so that the two cables 212 are compressed into the groove 220, and then the cable 212 is applied with tension through the cooperation of the protrusion 215 and the groove 220, so that the cable 212 drives the clamping block 133 to move toward the side close to the safety handle 2 along the through hole 211, and the two locking rods 124 rotate along the rotating shaft 122 under the elastic force of the extrusion spring 130, and drive the matching rod 126 to move away from each other, so as to realize manual quick release of the pet.

[0045] At the same time, the grooves 220 on the extrusion block 219 cooperate with the protrusions 215 to make the cable 212 bend along the surfaces of the multiple protrusions 215, thereby increasing the contraction distance of the cable 212, so that the clamping block 133 moves toward the side close to the safety handle 2. The distance is increased, ensuring that the opening distance of the matching rod 126 is sufficient to quickly release the collar, and avoiding the collar from being unable to be released smoothly due to the small opening distance of the matching rod 126; in addition, through the two groups of cables 212 and the pressing rod 218, when one of the groups is stuck, it can still operate normally, drive the matching rod 126 to open, and avoid the inability to release the restraint on the pet due to the stuck. At the same time, when the clamping block 133 moves toward the side close to the safety handle 2, the telescopic rod 213 adaptively contracts and the telescopic rod 213 is automatically locked, so that the clamping block 133 cannot be reset under the elastic force of the top spring 132, preventing the owner from letting go too quickly after pinching the pressing rod 218, so that the pet is not released in time and the matching rod 126 is closed, further improving the performance of the pet chain.

[0046] It should be noted that the telescopic rod 213 has an automatic telescopic locking mechanism in the prior art (not shown in the figure). The automatic telescopic locking mechanism can make the telescopic rod 213 shrink and automatically lock after being subjected to force, and will automatically extend and reset when subjected to force again, so as to facilitate repeated pulling of the clamping block 133 to control the extension and retraction of the telescopic rod 213, thereby facilitating the repeated use of the pet chain.

[0047] Reference Figure 4 and Figure 5As shown, in order to enable the pet to break free and get rid of danger by itself when the owner is not around and the pet is in danger, based on this, in the present embodiment, a support rod 41 is connected between the two rotating shafts 122, and a support spring 42 is installed on the side of the support rod 41 away from the leash 3, and sliding grooves 43 are provided on the upper and lower side walls of the accommodating groove 4, and a linkage block 44 is slidably connected in the sliding groove 43, and the end of the extrusion spring 130 away from the locking rod 124 connected thereto is connected to the linkage block 44, and two matching grooves 45 are provided on the two inner side walls in the width direction of the accommodating groove 4, and the length direction of the matching groove 45 is parallel to the length direction of the accommodating groove 4, and the two rotating shafts 122 are respectively located in the two matching grooves 45.

[0048] It should be noted that the support spring 42 always applies an elastic force to the support rod 41 toward the side close to the clamping block 133 , thereby preventing the matching rod 126 from opening.

[0049] In the specific implementation process, when the pet chain is tied to the fixed pile and the pet encounters danger and pulls the leash 3 hard, the leash 3 is straightened by the pet's pulling. When the pulling force of the pet is greater than the elastic force of the support spring 42, the pet drives the two matching rods 126 to move away from the safety handle 2 through the collar and drives the locking rod 124 and the limit rod 125 to move synchronously. The locking rod 124 slides along the clamping groove 129 and drives the extrusion spring 130 and the linkage block 44 to slide along the sliding groove 43. At the same time, the rotating shaft 122 slides along the matching groove 45 to the side away from the safety handle 2, and the rotating shaft 122 drives the support rod 41 to move synchronously. The supporting spring 42 contracts adaptively, and during the movement of the locking rod 124, it rotates relatively under the action of the extrusion spring 130 and drives the matching rod 126 to open. At this time, the clamping block 133 does not move under the action of the telescopic rod 213, so there is a distance between the locking rod 124 and the clamping block 133, so that the locking rod 124 can smoothly rotate to the side close to the clamping block 133. When the matching rod 126 is opened to a certain distance, the pet can easily break free from the matching rod 126, so that the pet can automatically break free, so that the pet can quickly escape from the dangerous area after breaking free to avoid being hurt.

[0050] Embodiment 2:

[0051] Reference Figure 6 and Figure 7As shown, on the basis of the first embodiment, in order to prevent the pet from being released from the restraints of the matching rod 126 due to the pet's sudden rush, based on this, in the present embodiment, two groups of moving grooves 51 are provided on the inner wall of the unlocking groove 214 away from the leash 3, each group of moving grooves 51 has two and are symmetrically distributed up and down, and a moving rod 52 is slidably connected in the moving groove 51, and the two moving rods 52 in each group of sliding grooves 43 are commonly connected to a pressing rod 54 on the side away from the leash 3, a moving spring 53 is connected between the moving rod 52 and the safety handle 2, and the two moving rods 52 in each group of moving grooves 51 are commonly connected to the side away from the pressing rod 54 There is a pressing block 55 located in the unlocking groove 214, and a matching block 56 corresponding to the pressing block 55 is installed on the inner wall of the unlocking groove 214. The pull rope 212 passes through the unlocking groove 214 and then bypasses multiple matching blocks 56. The pressing block 55 is provided with a corresponding groove 57 matching with the matching block 56 on the side close to the matching block 56. A snap-in box 58 is installed on either side of the safety handle 2, and a displacement groove 59 is provided on the side of the snap-in box 58 away from the pull rope 3. A top support block 60 is slidably connected in the snap-in box 58, and a sliding rod 61 located in the displacement groove 59 is connected to the top support block 60. The top support block 60 has an arc chamfer on the side close to the pressing rod 54.

[0052] In the specific implementation process, by pinching the two downward pressing rods 54 on the inner wall of the safety handle 2, the two downward pressing rods 54 drive the four moving rods 52 to slide synchronously along the moving groove 51 into the unlocking groove 214, and the moving spring 53 shrinks adaptively. The two moving rods 52 on each downward pressing rod 54 respectively drive the two downward pressing blocks 55 to move toward the side close to the matching block 56. The two downward pressing blocks 55 squeeze the cable 212, so that the two cables 212 are compressed into the corresponding groove 57, and then the matching block 56 and the corresponding groove 57 cooperate to apply tension to the cable 212, so that the cable 212 drives the clamping block 133 to move toward the side close to the safety handle 2 along the through hole 211, and the two locking rods 124 rotate along the rotating shaft 122 under the elastic force of the squeezing spring 130, and drive the matching rod 126 to move away from each other, so as to realize manual quick release of the pet; in addition, by pulling the sliding rod 61 along the displacement groove The push rod 54 is moved toward the side close to the push rod 54, and the sliding rod 61 drives the top support block 60 to slide to the side of the two push rods 54 close to the safety handle 2, so that when the owner accidentally touches and pinches the push rod 54, the resistance of the sliding rod 61 can prevent the push rod 54 from driving the matching rod 126 to open, thereby increasing the safety of the pet chain; further, installing the push rod 54 on the side of the safety handle 2 away from the leash 3 can prevent the owner from accidentally touching and pinching the push rod 54 to release the pet when the pet rushes out. When the pet is in danger and the sliding rod 61 is located at the bottom of the push rod 54, the push rod 54 is squeezed hard, and the push rod 54 squeezes the arc surface of the sliding rod 61. The sliding rod 61 slides into the card box 58 under the action of its arc surface, and the push rod 54 drives the matching rod 126 to open, thereby releasing the pet, avoiding the situation where the pet cannot be released in a critical situation due to the limitation of the sliding rod 61, thereby further improving the practicality of the present invention.

[0053] When working: the first step: pinch the pressing blocks 128 on both sides of the quick-release lock buckle 1, the pressing blocks 128 slide into the receiving groove 4 along the through groove 127 and squeeze the locking rod 124, the locking rod 124 rotates along the rotating shaft 122 toward the middle of the receiving groove 4, the squeezing spring 130 adaptively retracts, and the two locking rods 124 squeeze the clamping block 133 during the rotation process, so that the clamping block 133 moves toward the side close to the traction rope 3 under the squeezing action of the locking rod 124, the top spring 132 adaptively shrinks, and the two locking rods 124 slide along the clamping groove 129; at the same time, the locking rod 124 drives the limiting rod 125 to rotate along the rotating shaft 122 away from the middle of the receiving groove 4 and bring The movable matching rod 126 moves synchronously in the circumferential direction, so that the two matching rods 126 are opened. After the two matching rods 126 are inserted into the collar, the pressing block 128 is released, and the top spring 132 rebounds and drives the clamping block 133 to move away from the leash 3. The clamping block 133 squeezes the two locking rods 124, so that the two locking rods 124 rotate to the side away from the clamping block 133, and drives the limit rod 125 and the two matching rods 126 to move towards each other and clamp, thereby realizing the restraint of the pet. The mutual clamping of the two matching rods 126 can prevent the pet from struggling to break free for a long time, causing a gap between the two matching rods 126, affecting the restraint of the pet, and greatly improving the quality of the pet chain.

[0054] Step 2: When the owner is holding the pet and an emergency occurs, the owner can squeeze the two pressing rods 218 on the inner wall of the safety handle 2, so that the two pressing rods 218 drive the four connecting rods 217 to slide synchronously along the sliding groove 216 into the unlocking groove 214, and the reset spring 221 shrinks adaptively. The two connecting rods 217 on each pressing rod 218 respectively drive the two extrusion blocks 219 to approach the protrusion 215 and squeeze the cable 212, so that the two cables 212 are compressed into the groove 220, and then the cable 212 is pulled by the cooperation of the protrusion 215 and the groove 220. The cable 212 drives the clamping block 133 to move toward the side close to the safety handle 2 along the through hole 211, and the two locking rods 124 rotate along the rotating shaft 122 under the elastic force of the extrusion spring 130, and drive the matching rod 126 to move away from each other, so as to realize manual quick release of the pet.

[0055] At the same time, the grooves 220 on the extrusion block 219 cooperate with the protrusions 215 to make the cable 212 bend along the surfaces of the multiple protrusions 215, thereby increasing the contraction distance of the cable 212, so that the clamping block 133 moves toward the side close to the safety handle 2. The distance is increased, ensuring that the opening distance of the matching rod 126 is sufficient to quickly release the collar, and avoiding the collar from being unable to be released smoothly due to the small opening distance of the matching rod 126; in addition, through the two groups of cables 212 and the pressing rod 218, when one of the groups is stuck, it can still operate normally, drive the matching rod 126 to open, and avoid the inability to release the restraint on the pet due to the stuck. At the same time, when the clamping block 133 moves toward the side close to the safety handle 2, the telescopic rod 213 adaptively contracts and the telescopic rod 213 is automatically locked, so that the clamping block 133 cannot be reset under the elastic force of the top spring 132, preventing the owner from letting go too quickly after pinching the pressing rod 218, so that the pet is not released in time and the matching rod 126 is closed, further improving the performance of the pet chain.

[0056] Step 3: When the pet chain is tied to the fixed pile and the pet encounters danger and pulls the leash 3 hard, the leash 3 is straightened by the pet. When the pulling force of the pet is greater than the elastic force of the support spring 42, the pet drives the two matching rods 126 to move away from the safety handle 2 through the collar and drives the locking rod 124 and the limit rod 125 to move synchronously. The locking rod 124 slides along the clamping groove 129 and drives the extrusion spring 130 and the linkage block 44 to slide along the sliding groove 43. At the same time, the rotating shaft 122 slides along the matching groove 45 to the side away from the safety handle 2, and the rotating shaft 122 drives the support rod 41 to move synchronously The supporting spring 42 contracts adaptively, and during the movement of the locking rod 124, it rotates relatively under the action of the extrusion spring 130 and drives the matching rod 126 to open. At this time, the clamping block 133 does not move under the action of the telescopic rod 213, so a distance is generated between the locking rod 124 and the clamping block 133, so that the locking rod 124 can smoothly rotate to the side close to the clamping block 133. When the matching rod 126 is opened to a certain distance, the pet can easily break free from the matching rod 126, realizing automatic breaking free of the pet, so that the pet can quickly escape from the dangerous area after breaking free to avoid being hurt.

[0057] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
