Technical Field
[0001] This utility model relates to the field of pet leash technology, and in particular to a pet leash disconnection device. Background Technology
[0002] A pet leash, also known as a pet harness, is a link between a pet and its owner, ensuring that the pet can be effectively controlled and guided during outdoor activities. It is usually made of durable materials, such as nylon, cotton, or metal chains, to ensure that it can withstand the pulling force of the pet and the wear and tear during activities. A pet leash disconnect device is a device that can be disconnected in an emergency to protect both the pet owner and the pet.
[0003] Currently available pet leash disconnect devices have the following problems when in use:
[0004] Traditional pet leash disconnect devices may not detect smaller pet leashes when encountering automatic doors such as those in elevators or buses. As a result, the automatic doors may close directly and continue moving, leaving pet owners unable to react in time and potentially causing accidents to their pets. This significantly reduces the safety of the device. Utility Model Content
[0005] The main purpose of this invention is to provide a pet leash disconnection device, which aims to solve the technical problems in the prior art.
[0006] This utility model discloses a pet leash disconnection device, comprising: a connecting sleeve and a post; the post is inserted into the inner side of the connecting sleeve; a threaded tube is fixedly connected to the surface of the connecting sleeve; a first groove is formed on the surface of the post; a movable rod is inserted into the inner side of the first groove; the surface of the movable rod penetrates the connecting sleeve; a groove is formed on the surface of the movable rod; a connecting plate is fixedly connected to the surface of the movable rod; the bottom of the connecting plate is connected to the connecting sleeve by a spring; a second groove is formed on the surface of the post; a movable tube is slidably connected to the inner side of the second groove; the movable tube fits against the inner side of the threaded tube; the inner side of the movable tube is connected to the inner side of the second groove by a spring; and a leash is fixedly connected to the surface of the movable tube. The connecting rope passes through the second sliding groove, and the other end of the connecting rope is fixedly connected to a movable rod. When the pet and the pet owner are at opposite ends of the sensor door, and the sensor door continues to move, the pet owner will subconsciously loosen the pet rope. At this time, the first connecting band, supported by the tension spring, will slide in the gap of the sensor door. The movable tube, under the action of the tension spring, will insert into the threaded sleeve until the first connecting plate fits against the sensor door. During the continued movement, the first connecting plate will drive the movable rod to slide inward in the first sliding groove on the surface of the insertion post. The movable rod will pull the connecting rope to move the movable tube inward in the second sliding groove, thereby disengaging from the threaded tube and separating the insertion post from the connecting sleeve. At this time, the pet can be removed from the connecting sleeve, protecting the pet's safety.
[0007] Preferably, a sealing cap is fixedly connected to the surface of the insert, a sealing gasket is adhered to the surface of the sealing cap, and an elastic ball is fixedly connected to the surface of the insert. A circular groove is opened on the inner side of the connecting sleeve, and the elastic ball is inserted into the inner side of the circular groove. A threaded cap is threadedly connected to the surface of the threaded tube. In this way, when the insert is inserted into the connecting sleeve, the elastic ball fixedly connected to the surface of the insert insert is inserted into the circular groove opened on the inner side of the connecting sleeve, which adds a first layer of stabilizing structure. At this time, the sealing gasket on the surface of the sealing cap will press the surface of the connecting sleeve, which increases the sealing performance of the device. Then, by tightening the threaded cap, the connection between the movable tube and the threaded tube can be sealed, which facilitates the disassembly of the device and increases the sealing performance of the device, preventing moisture from entering and causing corrosion.
[0008] Preferably, a third sliding groove is provided on the inner side of the connecting sleeve, and a sliding sleeve is fixedly connected to the surface of the insert, and the third sliding groove is slidably connected to the surface of the sliding sleeve. Thus, the insert is connected to the sliding sleeve through the third sliding groove, which prevents the insert from sliding relative to the connecting sleeve when it is inserted into the inner side of the connecting sleeve, so that the threaded tube and the second sliding groove cannot be aligned, thereby increasing the rationality of the device.
[0009] Preferably, a first connecting strap is fixedly connected to the surface of the connecting sleeve, and a first perforation is provided on the surface of the first connecting strap. This first perforation reduces the weight of the device and greatly increases its convenience.
[0010] Preferably, a second connecting strap is fixedly connected to the surface of the sealing cover, and a sleeve is fixedly connected to the surface of the second connecting strap. In this way, the second connecting strap is at a certain distance from the sleeve on the pet, which prevents the pet from getting too close to the sensor door and being injured during the movement of the first connecting strap, thus increasing the safety of the device.
[0011] Preferably, the surface of the connecting plate is provided with a fixing hole, and a first connecting strap is inserted into the inside of the fixing hole. The fixing hole on the connecting plate prevents the first connecting strap from shaking randomly, which would prevent the connecting plate from being unable to provide effective support and protection, thereby increasing the stability of the device.
[0012] Preferably, a battery pack is installed on the surface of the connecting sleeve, and an indicator light is connected to the surface of the battery pack via wires. In this way, the indicator light on the surface of the connecting sleeve can be turned on by turning on the battery pack in a nighttime environment, making it convenient for passers-by to see and increasing the practicality of the device.
[0013] Preferably, a fixed sleeve is fixedly connected to the surface of the connecting sleeve, and a movable rod is inserted into the inner side of the fixed sleeve. The fixed sleeve on the surface of the connecting sleeve increases the contact area between the movable rod and the connecting sleeve, preventing the movable rod from shaking during movement and increasing the stability of the device.
[0014] The beneficial effects of this utility model are as follows:
[0015] By inserting a post inside the connecting sleeve, a movable rod inserted into the first groove on the surface of the post penetrates the connecting sleeve. A groove is formed on the surface of the movable rod. The bottom of the connecting plate, which is fixedly connected to the surface of the movable rod, is connected to the connecting sleeve by a spring. A movable tube is slidably connected to the inside of the second groove on the surface of the post. The inside of the movable tube is connected to the inside of the second groove by a spring, and a connecting rope is fixedly connected to the surface of the movable tube, penetrating the second groove. The other end of the connecting rope is fixedly connected to the movable rod. When the pet and the pet owner are at opposite ends of the sensor door, and the sensor door continues to move, the pet owner will subconsciously loosen the pet leash. At this time, the first connecting band, supported by the tension spring, will slide in the gap of the sensor door. The movable tube, under the action of the tension spring, will insert into the threaded sleeve until the first connecting plate fits against the sensor door. During the continued movement, the first connecting plate will drive the movable rod to slide inward in the first groove on the surface of the post. The movable rod will pull the connecting rope to move the movable tube inward in the second groove, thereby disengaging from the threaded tube and separating the post from the connecting sleeve. At this time, the pet can be removed from the connecting sleeve, protecting the pet's safety.
[0016] By attaching a sealing gasket to the surface of the sealing cap fixedly connected to the insert pin, and inserting an elastic ball into a circular groove inside the connecting sleeve, and threaded caps connected to the threaded tube, a first layer of stabilizing structure is added when the insert pin is inserted into the connecting sleeve. At this time, the sealing gasket on the surface of the sealing cap will press against the surface of the connecting sleeve, increasing the sealing performance of the device. Then, by tightening the threaded cap, the connection between the movable tube and the threaded tube can be sealed, which facilitates the disassembly of the device and increases its sealing performance, preventing moisture from entering and causing corrosion.

[0025] like Figures 1-5 As shown, this application provides a method for disconnecting a pet leash, including: a connecting sleeve 1 and a post 2. The post 2 is inserted into the inner side of the connecting sleeve 1. A threaded tube 10 is fixedly connected to the surface of the connecting sleeve 1. A first groove 3 is formed on the surface of the post 2. A movable rod 4 is inserted into the inner side of the first groove 3. The surface of the movable rod 4 penetrates the connecting sleeve 1. A groove 7 is formed on the surface of the movable rod 4. A connecting plate 5 is fixedly connected to the surface of the movable rod 4. The bottom of the connecting plate 5 is connected to the connecting sleeve 1 by a spring. A second groove 8 is formed on the surface of the post 2. A movable tube 9 is slidably connected to the inner side of the second groove 8. The movable tube 9 fits against the inner side of the threaded tube 10. The inner side of the movable tube 9 is connected to the inner side of the second groove 8 by a spring. A connecting rope 6 is fixedly connected to the surface of the movable tube 9. The connecting rope 6 penetrates the first groove 10. The second slide groove 8 has a movable rod 4 fixedly connected to the other end of the connecting rope 6. When the pet and the pet owner are at opposite ends of the sensor door and the sensor door continues to move, the pet owner will subconsciously loosen the pet rope. At this time, the first connecting band 17, supported by the tension spring, will slide in the gap of the sensor door. The movable tube 9 will be inserted into the threaded sleeve under the action of the tension spring until the first connecting plate 5 fits against the sensor door. During the continued movement, the first connecting plate 5 will drive the movable rod 4 to slide inward in the first slide groove 3 opened on the surface of the insert 2. The movable rod 4 will pull the connecting rope 6 to drive the movable tube 9 to move inward in the second slide groove 8, thereby disengaging from the threaded tube 10 and separating the insert 2 from the connecting sleeve 1. At this time, the pet can be removed from the connecting sleeve 1, protecting the pet's safety.
[0026] A sealing cap 13 is fixedly connected to the surface of the insert 2, and a sealing gasket 14 is adhered to the surface of the sealing cap 13. An elastic ball 15 is fixedly connected to the surface of the insert 2. A circular groove 16 is opened on the inner side of the connecting sleeve 1, and the elastic ball 15 is inserted into the inner side of the circular groove 16. A threaded cap 21 is threadedly connected to the surface of the threaded tube 10. In this way, when the insert 2 is inserted into the connecting sleeve 1, the elastic ball 15 fixedly connected to the surface of the insert 2 is inserted into the circular groove 16 opened on the inner side of the connecting sleeve 1, which adds the first layer of stabilizing structure. At this time, the sealing gasket 14 on the surface of the sealing cap 13 will press the surface of the connecting sleeve 1, which increases the sealing performance of the device. Then, by tightening the threaded cap 21, the connection between the movable tube 9 and the threaded tube 10 can be sealed, which facilitates the disassembly of the device and increases the sealing performance of the device, preventing moisture from entering and causing corrosion.
[0027] The inner side of the connecting sleeve 1 is provided with a third sliding groove 11. The surface of the insert 2 is fixedly connected to the sliding sleeve 12, and the surface of the sliding sleeve 12 is slidably connected to the third sliding groove 11. Thus, the insert 2 is connected to the sliding sleeve 12 through the third sliding groove 11, which prevents the insert 2 from sliding relative to the connecting sleeve 1 when it is inserted into the inner side of the connecting sleeve 1, so that the threaded tube 10 and the second sliding groove 8 cannot be aligned, thus increasing the rationality of the device.
[0028] A first connecting band 17 is fixedly connected to the surface of the connecting sleeve 1. A first through hole 18 is provided on the surface of the first connecting band 17. In this way, the weight of the device is reduced by the first through hole 18, which greatly increases the convenience of the device.
[0029] A second connecting strap 19 is fixedly connected to the surface of the sealing cover 13, and a sleeve 20 is fixedly connected to the surface of the second connecting strap 19. In this way, the second connecting strap 19 and the sleeve 20 on the pet are at a certain distance, which prevents the pet from getting too close to the sensor door and being injured during the movement of the first connecting strap 17, thus increasing the safety of the device.
[0030] The surface of the connecting plate 5 is provided with a fixing hole 22, and a first connecting strap 17 is inserted into the inside of the fixing hole. Thus, the fixing hole 22 on the connecting plate 5 prevents the first connecting strap 17 from shaking randomly, which would cause the connecting plate 5 to fail to provide effective support and protection, thereby increasing the stability of the device.
[0031] A battery pack 23 is installed on the surface of the connecting sleeve 1. An indicator light 24 is connected to the surface of the battery pack 23 via wires. In this way, the indicator light 24 on the surface of the connecting sleeve 1 can be turned on at night by turning on the battery pack 23, making it easier for passers-by to see and increasing the practicality of the device.
[0032] A fixed sleeve 25 is fixedly connected to the surface of the connecting sleeve 1. A movable rod 4 is inserted into the inside of the fixed sleeve 25. Thus, the fixed sleeve 25 on the surface of the connecting sleeve 1 increases the contact area between the movable rod 4 and the connecting sleeve 1, preventing the movable rod 4 from shaking during movement and increasing the stability of the device.
[0033] The technical principle of this utility model is as follows: When the pet and its owner are at opposite ends of the sensor door, and the sensor door continues to move, the pet owner will subconsciously loosen the pet leash. At this time, the first connecting strap 17, supported by the tension spring, will slide in the gap of the sensor door. The movable tube 9, under the action of the tension spring, will be inserted into the threaded sleeve until the first connecting plate 5 is in contact with the sensor door. During the continued movement, the first connecting plate 5 will drive the movable rod 4 to slide inward in the first groove 3 opened on the surface of the insert 2. The fixing sleeve 25 provided on the surface of the connecting sleeve 1 increases the contact area between the movable rod 4 and the connecting sleeve 1, preventing the movable rod 4 from shaking during movement and increasing the stability of the device. At this time, the movable rod 4 will pull the connecting rope 6 to drive the movable tube 9 to move inward in the second groove 8, thereby disengaging from the threaded tube 10 and separating the insert 2 from the connecting sleeve 1. At this time, the pet can be removed from the connecting sleeve 1, protecting the pet's safety. Furthermore, when the insert 2 is inserted into the connecting sleeve 1, the surface of the insert 2 is fixed. The insertion of the elastic ball 15 into the circular groove 16 inside the connecting sleeve 1 adds a first layer of stabilization. At this time, the sealing gasket 14 on the surface of the sealing cover 13 presses against the surface of the connecting sleeve 1, increasing the sealing performance of the device. Then, by tightening the threaded cover 21, the connection between the movable tube 9 and the threaded tube 10 can be sealed, which facilitates disassembly of the device and increases its sealing performance, preventing moisture from entering and causing corrosion. The insertion post 2 is connected to the sliding sleeve 12 through the third sliding groove 11, preventing the insertion post 2 from sliding relative to the connecting sleeve 1 when it is inserted into the inside of the connecting sleeve 1, thus preventing the threaded tube 10 from not being aligned with the center of the second sliding groove 8, and increasing the rationality of the device. The fixing hole 22 on the connecting plate 5 prevents the first connecting band 17 from shaking arbitrarily, which would cause the connecting plate 5 to fail to provide effective support and protection, thus increasing the stability of the device. The indicator light 24 on the surface of the connecting sleeve 1 can be turned on by opening the battery pack 23 in the night environment, making it easy for passers-by to see and increasing the practicality of the device.
