Influence.
In a kind of wherein optional embodiment, the locking closure 5 is made of plastics, the inner cavity 51 of locking closure 5 and described fast
Tear the outer wall interference fit of tapered end 4 open;When to need to cover locking closure 5, firmly locking closure 5 can be placed on Quick Release lock by pushing tow locking closure 5
On first 4 outer wall, when needing to remove locking closure 5, the firmly drawing of locking closure 5 is held.
In another optional embodiment, external screw thread 46 is arranged in the outer wall of the Quick Release tapered end 4, the locking closure 5
Inner cavity 51 is provided with the internal screw thread 52 to match with the external screw thread 46;When to need to cover locking closure 5, locking closure 5 is tightened in fastly
It tears open on tapered end 4, when needing to remove locking closure 5, locking closure 5 is backed out by Quick Release tapered end 4, it is very convenient.
Preferably, the outer wall of locking closure 5 is provided with anti-skid chequer 53.
Preferably, as shown in figure 3, in order to guarantee lock pin 42 move axially flexibility, the leading portion 421 and back segment of lock pin 42
422 end is cambered surface round end;Meanwhile the bolt 32 of the Quick Release plug 3, the corner of end point have also carried out rounding and have added
Work.
Working principle is as follows:
When needing front shroud 1 and fixed back cover 2, first each Quick Release plug 3 is aligned with each Quick Release tapered end 4, then by Quick Release
The bolt 32 of plug 3 is inserted into the cylindrical groove 41 of Quick Release tapered end 4, locking closure 5 is placed on 4 outer wall of Quick Release tapered end later, when locking closure 5
When being gradually inserted in, the flaring 511 of locking closure 5 gradually can push two lock pins 42 to move axially and be gradually inserted into first through hole 33
In, from Quick Release plug 3 is locked on Quick Release tapered end 4 (as shown in figure 4, for locking closure 5 be completely nested after schematic diagram), Jin Ershi
Existing front shroud 1 is fixedly connected with back cover 2, wherein when design, the depth that each lock pin 42 is inserted into first through hole 33 should not be less than first
The 1/4 of 33 hole depth of through-hole, i.e., after two lock pins 42 are inserted into, at least half of first through hole 33 is inserted by lock pin 42.
When needing to dismantle front shroud 1, locking closure 5 is backed out into (or extraction), lock pin 42 loses limitation, under the action of spring 44
Meeting automatic spring, being detached from first through hole 33 can pull out, and then front shroud 1 so that Quick Release plug 3 is unlocked from Quick Release tapered end 4
It can be removed.
After the present embodiment, when the front shroud 1 and back cover 2 of electric fan are fixed, it is only necessary to be directed at Quick Release plug 3 and be inserted into fast
It tears open in tapered end 4, is then inserted in locking closure 5, very fast;When disassembly, it is only necessary to which Panasonic's locking closure 5, Quick Release plug 3 will be with Quick Release
Tapered end 4 separates, and then can remove front shroud 1, equally very quick and easy;As it can be seen that being not necessarily to when installation, disassembly front and back cover 1,2
It by any auxiliary tool, only can be completed manually, and the connection after installation will not loosen easily also than stronger.
