Detailed description of the invention
Comparison accompanying drawing, the present invention will be further described.
GIS current transformer anti-bird rosette includes supporting plate 1, several screw rod 5 is fixedly mounted on supporting plate 1, coordinate on screw rod 5 and first nut 6 and the second nut 7 is installed, between first nut 6 and the second nut 7, upper box cover 3 is set and touches the most therewith, lower casing 2 is set between supporting plate 1 and upper box cover 3, lower casing 2 lower end touches with supporting plate 1, inwall border, lower casing 2 upper end arranges the first baffle plate 26, upper box cover 3 lower end outer wall border arranges second baffle 27, first baffle plate 26 is positioned at above second baffle 27, and the first baffle plate 26 and second baffle 27 are between lower casing 2 and upper box cover 3.The height of upper box cover 3 can be regulated by nut according to the height of terminal, and lower casing 2 is always positioned on the second baffle 27 of upper box cover 3 under gravity, and birds enter difficulty, and staff only need to lift lower casing 2 and can open rosette, convenient operation.
nullThe probability of rosette is opened in order to reduce birds，Reduce risk，Hole, several location 9 is offered in the first described baffle plate 26 lower end，Second baffle 27 upper end arranges several fixing bar 8，Fixing bar 8 is positioned at the hole, location 9 of correspondence，Cross through hole 10 is offered on fixing bar 8，The first connecting hole 14 is offered in the side in hole 9, location，In first connecting hole 14, first connecting rod 12 is installed，First spring 20 is installed on first connecting rod 12，The opposite side in hole 9, location offers the second connecting hole 13 and locating slot 15，In second connecting hole 13, second connecting rod 11 is installed，First tooth bar 17 is set on second connecting rod 11，Gear 16 and the second tooth bar 19 are installed in locating slot 15，Second tooth bar 19 is arranged on third connecting rod 18，Third connecting rod 18 length direction is 90 ° with the length direction of second connecting rod 11，Gear 16 engages with the first tooth bar 17 and the second tooth bar 19 respectively，One end of third connecting rod 18 is connected with the second spring 25.This structure can complete the locking of high intensity, makes upper box cover 3 and lower casing 2 fixation, and operated by personnel is convenient, avoids birds to open rosette simultaneously.When lower casing 2 is installed, the hole 9, the location fixing bar 8 on second baffle 27 of the first baffle plate 26 lower end is pressed, fixing bar 8 is made to insert in the hole, location 9 of the first baffle plate 26, while fixing bar 8 enters hole 9, location, second connecting rod 11 is promoted by inclined-plane 23 on fixing bar 8 to the left, thus driven gear 16 rotates, while gear 16 rotates, drive and on the second tooth bar 19, move compression the second spring 25, when second connecting rod 11 enters in cross through hole 10, second connecting rod 11 promotes the second tooth bar 19 to move down under the counteracting force of the second spring 25, driven gear 16 inverts simultaneously, the first tooth bar 17 reverse push power given by gear 16, second connecting rod 11 is made to be locked in cross through hole 10, make the first baffle plate 26 and second baffle 27 secure lock.During dismounting, promote first connecting rod 12 to move to left, make second connecting rod 11 be moved to the left and exit cross through hole 10 and unlock, be lifted up lower casing 2 and lower casing 2 can be made to depart from upper box cover.On the axle of gear 16 of the present invention, antivibrator is set.
It is inclined-plane that described first connecting rod 12 is positioned at one end of the first connecting hole 14, it is simple to advance and eject second connecting rod 11.
In order to realize installing or removing faster, described second connecting rod 11 is the conical surface 24 near one end of hole 9, location inwall.
The lower end of fixing bar 4 of the present invention arranges inclined-plane 23, and inclined-plane 23 is two, is symmetrically distributed in the first connecting hole 14 and port position of the second connecting hole 13, and its inclined-plane coordinates with the inclined-plane of first connecting rod 12 and second connecting rod 11, realizes fast assembling-disassembling further.
The outer end of the first connecting hole 14 of the present invention arranges boss 21, and first connecting rod 12 arranges block 22, to meet the first spring 20 compression energy.
