Description
Technical field
The utility model relates to bathroom fields, more particularly to a kind of adjustable lavatory lid slow descending mechanism.
Background technique
In general, the damper used on lavatory lid, under identical use state, damping force is fixed and invariable, and
Same damper is mounted on different lavatory lid, and the folding time of lavatory lid is different and different client couple
The folding time demand of lavatory lid is also different, therefore existing damper leads to damper because damping force is non-adjustable
Use scope be very restricted.In order to solve this problem, utility model patent 201521102619.X is disclosed
Enclosure interior space is separated two high pressure chests and two low by " a kind of damper of resistance-adjustable ", including shell, insertion shell
Press the shaft of chamber, interface channel between high pressure chest and low pressure chamber is closed when shaft is rotated towards first direction and in shaft towards the
Two directions are opened when rotating, and shell has a bottom plate, are further included the oil pocket of crossing being arranged in below Housing Base, are equipped in the middle part of bottom plate
Oil-through hole, plate upper surface are equipped with the oil groove of crossing for connecting oil-through hole and low pressure chamber, and bottom plate, which is equipped with, to be connected high pressure chest and cross oil pocket
Through-hole；It further include that the regulating part for crossing pasta product in oil pocket for adjusting oil-through hole was set.Regulating part can be used for adjusting oil
The product of pasta excessively in hole, when the product of pasta excessively of oil-through hole is smaller, oil liquid flows through slowing for oil-through hole, the damping force of damper
Increased, when the product of pasta excessively of oil-through hole is larger, the speed that oil liquid flows through oil-through hole becomes faster, and the damping force of damper obtains
Reduce, which has the advantages that resistance-adjustable section, however, the regulating part of the damper be provided at shell inner space it
Outside, such structure needs to design independent type chamber in the tail end of product, so that the length of product increases, volume becomes larger.
Secondly, traditional oil damper, needs specially to open up an aperture in the shell tail portion of damper, it is used for oiling, this
The technological operation difficulty of method is higher.
Utility model content
The purpose of this utility model is to provide a kind of adjustable lavatory lid slow descending mechanisms, to optimize existing product
Construction.
To achieve the goals above, the technology employed by the present utility model is

310, lead to and is equipped with unidirectional valve collar 4 in oil groove 310.
The damper course of work of above structure is as follows:
Slow descending mechanism using the above scheme, as shown in Figure 10 and Figure 11, first half term of the lavatory lid in lifting process
When, piston 3 moves from left to right, at this point, oil-gap was formed between unidirectional valve collar 4 and piston 3,3 exterior space of piston -- first
The damping oil of space A mainly by logical oil groove 310 to the inner space of piston 3 -- second space B flows, hinder at this time mud oil by
Resistance it is smaller, lavatory lid lifting be easy；Lavatory lid lifting process the second half, piston 3 continuation move from left to right,
Gap between 2 second half section of piston 3 and shaft is gradually increased, and the damping oil of 3 exterior space of piston can be by leading to oil groove 310 and living
Gap between plug 3 and shaft back segment 22 is flowed to the inner space of piston 3, and the resistance that resistance mud oil is subject at this time is smaller, closestool
Cover board lifting is more easier；
When first half term of the lavatory lid in the process of decline, as shown in Figure 12 and Figure 13, piston 3 moves from right to left, this
When, unidirectional valve collar 4 is bonded without oil-gap is crossed with shell 11 and piston 3, and the damping oil of 3 inner space of piston -- second chamber B is logical
Cross exterior space of the gap between piston 3 and shaft back segment 22 to piston -- first chamber A flowing hinders what mud oil was subject at this time
Resistance very little, lavatory lid decline are easy；When the second half of lavatory lid in the process of decline, the continuation of piston 3 moves from right to left
It is dynamic, and the gap between piston 3 and cylindrical section 221 is smaller and smaller, hindering the resistance that mud oil is subject at this time becomes larger, lavatory lid decline
Speed slows down, as shown in Figure 14 and Figure 15；When piston motion to the leftmost side, as shown in Figure 16 and Figure 17, damping oil passed through oil
Pore 2210 is flowed through oil-through-hole 220 to the exterior space of piston 3, at this point, the resistance that damping oil is subject to is maximum, lavatory lid
Group slowly landing.
In above process, by the adjusting screw rod 23 in rotation adjustment hole 210,23 end of adjusting screw rod and mistake is adjusted
Overlapping area between oily stria 2211, so that the area of passage of oily pore 2210 was adjusted, to realize the tune of damping size
Section control, especially decrease speed of the control lavatory lid in decline process the second half.In above-mentioned construction, because of adjusting screw rod 4
It is 21 part of central spindle for being embedded at shaft 2, the useful space outside axle sleeve 1 is not occupied individually, so that the axial length of product
It greatly reduces, product structure more minimizes.
Because of the special tectonic of above-mentioned slow descending mechanism, as shown in Figure 18 and Figure 19, it can be carried out by the following method very
Empty oiling:
It walks after poly- a. assembles main part of the damper in addition to adjusting screw rod and sealing ring and is placed in vacuum tank 6
In；
Poly- b. is walked to vacuumize vacuum tank 6；
It walks poly- c. and protrudes into 7 mouth of oiling needle and carry out oiling in adjustment hole 210；
Poly- d. is walked after reaching preset injection flow, product is taken out, then lock adjusting screw rod 23, seals aperture 2104, is prevented
Only leak.
The relatively traditional oil damper of above-mentioned correction oil injection method needs specially to open up an aperture in the shell tail portion of damper
For the method for oiling, the flexibility of this method operation is bigger, is more convenient.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any improvement done on the basis of technical solutions and equivalent replacement,
It each falls within scope of protection of the utility model.
