Technical Field
The invention relates to the field of pet equipment, in particular to an improved device for automatically disconnecting a dog leash and a control method thereof.
Background
Car doors, i.e. the doors seen inside the elevator car in the elevator, are opposite the landing doors, i.e. the doors seen when calling outside.
The elevator mainly comprises a touch panel elevator and a light curtain elevator.
A touch plate type elevator is provided, wherein an elevator door is provided with a protruding touch plate, and when an object touches the touch plate, the door can automatically spring open.
The light curtain type elevator has two ray sensors installed to the door of elevator, and when some matter blocks the ray, the door will be opened automatically.
The elevator is provided with a door lock, and the elevator has two necessary conditions for operation, namely the elevator door is closed and the door lock is closed.
The child hand model was used by a reporter, and as a result, the elevator was not only clamped but also continued to run. The safety device of the door is arranged at the upper end, if a child is short and the position of a hand extending to the lower end, the situation that the elevator is clamped or closed can occur, and the hands of the elevator can be injured when the elevator runs.
If the elevator is repaired over time or maintained improperly, the door clearance is too large, so that the situation that the elevator clamps foreign matters to continue running can occur.
When people take the elevator, people often see that the pets are taken on the elevator, and the 24 regulations clearly stipulate that the dogs taking the elevator or going up and down the stairs should be put into dog bags, dog cages, arms or mouth sleeves and avoid peak hours. However, the above regulations can be observed for a few people, the carelessness and negligence of the owner can cause great safety hazards to pets, people can often see and hear a tragedy caused by the negligence of the owner, a puppy runs out of the elevator when the elevator door is closed, the elevator door directly goes upwards after being closed, a dog belt sleeved on the neck or the back of the dog lifts the dog up in the air, and the elevator is also blocked in the air.
Due to the portability of the design, the dog belt is generally very thin, and the elevator door can be continuously closed when the dog belt is clamped; in order to prevent the dog belt from being broken by collision of the puppy, the quality of the dog belt is generally good, when the elevator door is directly lifted upwards after being closed, the dog belt sleeved on the neck or back of the dog lifts the dog in a flying manner without breaking, so that a pair of technical contradictions exist, and under general conditions, the quality of the dog belt is good enough to prevent the broken puppy from running; in special cases, such as when a dog is in an elevator, the dog strap is clamped, the quality of the dog strap is poor enough, so that the dog strap can be broken, the dog is protected to the maximum extent, damage to the dog and the elevator is reduced, and the dog strap can be broken automatically according to conditions and preferably can be manually controlled.
The invention relates to an automatic dog belt disconnecting device and a control method thereof, which have complicated structures, when an upper bottom plate of a metal clamp enters a groove of a buckle, all pulling force applied to the buckle is applied to the upper bottom plate of the metal clamp, the right side of the upper bottom plate of the metal clamp is tightly contacted with the right side of the inner wall of a fixed block, the impact force generated by a dog is applied to the right side of the inner wall of the fixed block, an eccentric wheel is driven by a motor to rotate to support the upper bottom plate, so that the upper bottom plate of the metal clamp is rotated out of the groove of the buckle, the requirement on the performance of the motor is high, the force applied to the upper bottom plate of the metal clamp by the eccentric wheel is vertical to the force applied to the upper bottom plate of the metal clamp by the buckle, and therefore, the motor.
