Abstract
The automatic dog band improvement device that disconnects passes through button transmission pop-up signal, after main control module receives pop-up signal, driving unit is driven motor, eccentric the distance between briquetting and left support column are adjusted by the handle on transmission device rotating eccentricity briquetting top, compression is realized with this and unclamps the first traction rope being located between eccentric briquetting and left support column, is disconnected dog band with this.People can according to circumstances select to disconnect dog band device, meanwhile, dog band device can automatically be disconnected according to extruding situation, and doggie is protected to the greatest extent with this, reduce the damage caused by doggie and elevator, easy to operate, convenient, it is easy to accomplish and promote.The present invention proposes that a kind of automatic dog band that disconnects improves control method simultaneously.
Description
Technical field
The present invention relates to pet clothing arts, and in particular to a kind of automatic dog band that disconnects improves device and its control method.
Background technology
Gate is that elevator shuts the door that the inside is seen in elevator, with hall door（Or layer door）, i.e. call when institute outside
The door seen is opposite.
Elevator mainly has two kinds of touch panel type elevator and light veil type elevator.
Touch panel type elevator has one piece of prominent touch panel on elevator door, and when having the article to encounter touch panel, door will automatically spring open.
Light veil type elevator is equipped with two ray sensing devices on elevator door, and when there is object to stop ray, door will be certainly
It moves out.
There is a door lock above elevator, there are two necessary conditions, not only elevator door to close for elevator operation, also wants door close
Lock.
Once reporter is tested with children's fingerprint, as a result elevator has not only clamped children's fingerprint, but also continues to run with.
The safety device of door is all in upper end, if child is shorter and smaller, the position stretched out one's hand is on lower side, it is possible to after being jammed
The situation that elevator is still closed, at this moment elevator operation may can hurt hand.
If elevator is long neglected and in disrepair or maintenance is improper, it is excessive to also result in a gap, is possible to elevator occur in this way
Clamp the situation that foreign matter continues to run with.
It often can be appreciated that someone goes up elevator with pet when we take elevator,《Regulations》24 clearly stipulate that " take dog to multiply
Elevator or stair activity are sat, dog should only be packed into dog bag, dog cage, bosom or wears muzzle, and avoid rush hour.”
However, can abide by it is above-mentioned as defined in people it is very few, paying no attention to and neglecting very big safety can be caused to pet due to owner
Hidden danger, we often can see and hear carelessness due to owner and caused by each tragedy, doggie will in elevator door
Elevator, elevator door direct uplink after closing are run out of during closing, dog is soared aloft to hang by the dog band for being sleeved on dog neck or dog back
It rises, therefore elevator is also stuck in the air.
Due to the portability of design, dog band is general all very thin, and elevator door will continue to be closed when clamping dog band；It is small to prevent
Dog band snaps when dog collides, and generally all very well, direct uplink after elevator door is in closing is sleeved on dog neck or dog to the quality of dog band
Dog is soared aloft to sling without being broken by the dog band of back, therefore there is a pair of technical contradiction here, under normal circumstances,
The quality of dog band is good enough, to prevent dog band fracture doggie from running chaotically；Under special circumstances, such as doggie when taking elevator dog band
It is stuck, the quality of dog band is poor enough, dog band is enable to be broken with this, doggie is protected to the greatest extent, reduction pair
Caused by doggie and elevator damage, and this dog band fracture preferably can taking human as control, dog band can be according to circumstances
It is automatic to disconnect.
The structure of invention " automatic to disconnect dog with device and its control method " is more complicated, when the upper plate of metal clip enters
After into the groove of buckle, all pulling force being subject to that are buckled are applied to above the upper plate of metal clip, metal clip upper plate
Right side and the right side of fixed block inner wall are in close contact, and the impact force that doggie generates can be applied to the right side of fixed block inner wall, pass through
Motor band movable eccentric wheel rotation supports upper plate, metal clip upper plate is made to be produced from the groove of buckle, this is to electricity
The performance requirement of motivation is very high, the power phase that eccentric wheel applies metal clip upper plate with buckle the power that metal clip upper plate applies
It is mutually vertical, therefore motor will have sufficiently large torque, fully overcome pressure and frictional force suffered by metal clip.
Invention content
In view of the above defects of the prior art, the invention solves a technical problem be that doggie is in elevator
Door runs out of elevator when will close, and after closing during direct uplink, people can according to circumstances be selected elevator door by control device
It selects and disconnects dog band device, doggie is protected.
Another to be solved technical problem is that doggie has run out of elevator when elevator door will close, and elevator door is closing
Rear direct uplink is closed, the dog band being sleeved on dog neck soars aloft dog after slinging, and dog band can automatically be disconnected according to extruding situation, with
This to the greatest extent protects doggie, reduces the damage caused by doggie and elevator.
The present invention is realized by using following technical scheme, is improved and is filled by the automatic disconnection dog band of this purpose design
