There is through-hole, the through-hole is respectively arranged on 105 anter bottom of third stretching frame around friction-proof piece, the second connecting shaft block 1052 is equipped with
End.
A kind of Anti-fall safety device for the fan door lifting structure, including Anti-fall safety device 2:
Described bleed off falls safety device 2 and is respectively arranged on inside 105 anter of third stretching frame, and described bleed off falls safe dress
Setting 2 includes Lanyard 201, repulsion block 202, sliding block 203 and brake block 204, and described 201 one end of Lanyard passes through institute
It states the through-hole that third stretching frame 105 is provided with to connect with sliding block 203, the safety rope traction rope 201 is far from 203 one end of sliding block and institute
The fixed frame 102 stated connects, and the repulsion block 202 is set to 203 top of sliding block, and the brake block 204 is set to the rotary shaft 101
End face.
Second stretching frame 104 limits the first stretching frame 103, second stretching frame by the first gear fixture block 1041
104 are stretched by the first connecting shaft block 1042 by rotary shaft 101.
The third stretching frame 105 limits the second stretching frame 104, the friction-proof piece material by the second gear fixture block 1051
It can be glue material or metal, the third stretching frame 105 is stretched by the second connecting shaft block 1052 by rotary shaft 101.
The third stretching frame 105 is stretched by the second gear fixture block 1051 and the first limit first simultaneously of gear fixture block 1041
Display Rack 103, the second stretching frame 104, first stretching frame 103, the second stretching frame 104 and third stretching frame 105, which are presented, to be folded
Structure.
The fan door frame 1 is stretched by rotary shaft 101 at curvature of the spinal column formula.
By spacing relation, in stretching, extension, first stretching frame 103 can first stretch the fan door frame 1, then to second
Stretching frame 104 stretches, and finally arrives the stretching, extension of third stretching frame 105, is stretched by level shape similar to turtleback shape.
User can adjust stretching frame according to the variation of usage scenario when fanning door frame 1 using elevating mechanism of the invention
Size or quantity.
The second connecting shaft block 1052 is synchronous with 203 position of sliding block.
The repulsion part 202 is lifted by Lanyard 201 by sliding block 203 and generates repulsion, and the repulsion part 202 can be
Homopolar magnet or high-elastic spring, the sliding block 203 are launched by the repulsion of repulsion part 202.
The sliding block 203 can be acute angle sliding block or cylinder sliding block, and the brake block 204 can be acute angle tooth block or cylinder tooth
Supplementary angle, the sliding block 203 are mentioned the block between cog of block, the sliding block 203 and the brake block 204 by Lanyard 201 each other
After drawing, 203 end point of sliding block is at a distance from 204 overall diameter face of brake block in 2-3mm.
Section arc length after 201 length of Lanyard is fully extended with fan door frame 1 is identical, and the third is stretched
Display Rack 105 is limited by the Lanyard 201, repulsion block 202 and sliding block 203.
When user using the present invention according to the variation of usage scenario, after the size or quantity that adjust stretching frame, Yong Huye
Section arc length adjusts 201 length of Lanyard, the number of also with good grounds stretching frame after being stretched accordingly according to stretching frame
Amount adjusting Lanyard 201 uses diameter.
Described 201 one end of Lanyard is connect by the through-hole that the third stretching frame 105 is provided with sliding block 203, institute
It states through-hole to surround equipped with friction-proof piece, when Lanyard 201 is connect by through-hole with sliding block 203, it is therefore prevented that Lanyard
201 directly contact with through-hole, and Lanyard 201 is caused to cause to wear, and influence the service life that Lanyard 201 uses.
It is synchronous with 203 position of sliding block by the second connecting shaft block 1052, it is ensured that when the present invention triggers Anti-fall
When safety guard, it can be limited by 203 pairs of sliding block ejections with brake block 204, so that related limit third stretching frame 105
Position, at the same it is right by the first gear fixture block 1041 of the second gear fixture block 1051 and the second stretching frame 104 of third stretching frame 105
Fan door stretching frame part of the invention carries out efficiently precisely limit.
Anti-fall safety device of the invention provides two-part safeguard protection:
First segment protection: by 201 pairs of liftings of the invention of Lanyard, fan door frame 1 of the invention is effectively prevented
Hyper-extended causes damages to the life security of people.
According to Fig. 9: second segment protection: after the sliding block 203 is lifted by Lanyard 201, the sliding block 203 is right
Repulsion part 202 compresses, to make repulsion part 202 constantly generate repulsion, when in the use of the present invention, when Lanyard 201 exists
The fracture of any one position, the sliding block 203 will lose the power of lifting, at the same repulsion part 202 can pressure release repulsion, to sliding block
203 are launched towards 204 direction of brake block, and because 203 end point of sliding block is smart at a distance from 204 overall diameter face of brake block
Standard so that precisely efficient limit brake block 204 by launching sliding block 203, passes through 203 pairs of sliding block brakings to very small
Dynamic 204 limit, to pass through first grade of the second gear fixture block 1051 of third stretching frame 105 and the second stretching frame 104 simultaneously
1041 pairs of fixture block of position fan door stretching frame parts of the invention carry out efficiently precisely limit, and making to fan door stretching frame will not be further continued for
It falls, protects the life security of people.
The present invention causes the stretching frame of fan door illegally to fall, jeopardizes to eliminate fan door part aging and parts depreciation
The life security of people, there are also the use scopes for increasing fan door, propose the lifting structure and its Anti-fall safety of a kind of fan door
Device eliminates fan door stretching frame and illegally falls by being equipped with the devices such as Lanyard 201, repulsion block 202 and sliding block 203
Danger and considerably increase fan door use scope.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
Scope of patent protection of the invention is included in other related technical areas.
