A kind of toilet lid delays to fall hinge
Technical field
The invention belongs to hinge technical field, is specifically that a kind of toilet lid delays to fall hinge.
Background technology
Toilet lid is required to quickly dig when digging, and drop in order to prevent when turning over send very big sound or
Person prevents toilet lid from breaking general be provided with hinge and delaying to fall structure, and existing toilet cover hinge is typically all by setting
Put the mechanical structures such as torsional spring realize toilet lid it is slow fall, and existing complex, high processing costs of delaying to fall hinge arrangement, it is difficult to
Suitable for the toilet lid of different weight.
The content of the invention
For the present invention in view of the shortcomings of the prior art, providing a kind of toilet lid delays to fall hinge, this toilet lid delays to fall hinge to not
Toilet lid with weight can play and delay to fall effect well, and simple in structure, easy to process.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:A kind of toilet lid delays to fall hinge
Chain, including cylindrical shell, section is provided with the housing as fan-shaped shaft, is provided with projecting piece in the housing, institute
The center that projecting piece is extended to the shaft by the shell rim is stated, the housing, the shaft are stretched out in the shaft both ends
Circular passage is inside provided with, the circular passage side is provided with block opposite side and is provided with rotatable lamella, when hinge is static when institute
Rotatable lamella is stated to fit on the block.This toilet lid delays to fall hinge when toilet lid falls since rotatable lamella and block paste
Close, the air of shaft front end can not flow to shaft rear end by circular passage, and the air of shaft front end is between shaft and housing
Gap flow to the rear end of shaft, therefore air flow is slower, and toilet lid drops slowly, when toilet lid is opened due to rotatable lamella
It can rotate, produce gap between rotatable lamella and block at this time so that circular passage connects, and the air of shaft rear end can be quick
The front end of shaft is flowed to, so that toilet lid can be opened quickly.
In above-mentioned technical proposal, it is preferred that filled in the cavity of the housing and be provided with liquid.Due to the flowing speed of air
Degree quickly, delays to fall that effect is undesirable, and filled in housing have liquid so that the hinge it is slow fall effect it is more preferable.
Compared with prior art, the present invention have the advantages that:This toilet lid delays to fall hinge and falls in toilet lid
When be bonded with block due to rotatable lamella, the air of shaft front end can not flow to shaft rear end by circular passage, shaft front end
Gap of the air between shaft and housing flows to the rear end of shaft, therefore air flow is slower, and toilet lid drops slowly, works as horse
Since rotatable lamella can rotate when bung is opened, gap is produced between rotatable lamella and block at this time so that circular passage connects, and turns
The air of shaft rear end can quickly flow to the front end of shaft, so that toilet lid can be opened quickly.
Brief description of the drawings
Fig. 1 is the structure diagram of hinge of the embodiment of the present invention.
Fig. 2 is structure diagram when the hinged toilet lid of the embodiment of the present invention falls.
Fig. 3 is structure diagram when the hinged toilet lid of the embodiment of the present invention is opened.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings:It is a kind of referring to Fig. 1 to Fig. 3
Toilet lid delays to fall hinge, including cylindrical shell 1, section is provided with the housing 1 as fan-shaped shaft 2, in the housing 1
Projecting piece 11 is provided with, the projecting piece 11 is extended to the center of the shaft 2,2 both ends of shaft by 1 edge of housing
The housing 1 is stretched out, circular passage 21 is provided with the shaft 2, it is another that 21 side of circular passage is provided with block 22
Side is provided with rotatable lamella 23, and when hinge is static, the rotatable lamella 23 is fitted on the block 22.This toilet lid delays to fall hinge
When toilet lid falls since rotatable lamella 23 is bonded with block 22, the air of shaft front end can not be flowed to by circular passage to be turned chain
Shaft rear end, the gap of the air of shaft front end between shaft and housing flows to the rear end of shaft, therefore air flow is slower, horse
Bung drops slowly, when toilet lid is opened since rotatable lamella can rotate, produces gap between rotatable lamella and block at this time, makes
Circular passage connection is obtained, the air of shaft rear end can quickly flow to the front end of shaft, so that toilet lid can be quick
Open.
Filled in the cavity of the housing 1 and be provided with liquid.Due to air flowing velocity quickly, delay to fall effect and pay no attention to
Think, and in housing fill have liquid so that the hinge it is slow fall effect it is more preferable.
