Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of Large Copacity pulsator washing machine lid descent control device of the utility model example, comprises lower support frame 1, upper bracket 2, pair of parallel duplex pull rod 3,4 and linear type damper 5; Described upper bracket 2 is riveted by bearing pin 6 with described lower support frame 1; One end and the described upper bracket 2 of described pair of parallel duplex pull rod 3,4 are riveted by bearing pin 7, and the other end and described lower support frame 1 are riveted by mobilizable mode bearing pin 8; Described linear type damper 5 one end is fixed on described lower support frame 1 by bearing pin 9 riveted joint, the other end is connected on the bearing pin 8 that described pair of parallel pull bar 3,4 is connected with described lower support frame 1, constitutes one to connect the entirety that the bearing pin 6 of described carrier parts is rotating center.
Lower support frame 1 is with screw locking in ladle body, and upper bracket 2 uses screw locking on cover plate; When the closure is closed, upper bracket 2 is driven to rotate centered by bearing pin 6, under the effect of bearing pin 7, drive pull bar 3,4 to pull the bearing pin 8 compression damping device of the pull bar the other end to move to the left along horizontal concrete chute 10, bearing pin 9 is fixed holes, fixing damper tail end is motionless, the resistance that damper rod is produced by compression damping device, the motion speed controlling bearing pin 8 reaches the result making cover plate slowly closing.
Again as shown in figures 1 and 3, linear type damper 5 comprises housing 11, end cap 12, piston 13, throttle valve plate 14, spring seat 15, end bracket enclosed 16, rod seal 17, piston seal 18, piston rod 20, rod end connecting lug 21, valve block spring 22, tail stifled 23.
End bracket enclosed 18, rod seal 17 and tail block up the airtight environment of 23 composition one, make the fluid being filled with cavity not to external leakage, tail stifled 23 bores a transverse holes and is fixed on lower support frame 10 by bearing pin 9, piston rod 20 is by being threaded into earrings 21, and the hole on earrings is fixed in the horizontal slip groove of lower support frame 1 by bearing pin 8; Bearing pin 7,8 all there is several positioning ring for keeping the operating attitude of linear type damper about 5 both direction, preventing the plane of inclination that left and right directions occurs during work from damaging damper.
By piston 13, throttle valve plate 14, valve block spring 22, the open and close type throttle orifice 19 that spring seat 15 forms is cores that the thrust of linear type damper 5 produces; Throttle valve plate 14 is adjacent to piston 13 surface and forms an annular open and close type throttle orifice 19 with the circular groove on piston 13 surface under the effect of valve block spring 22, open and close type throttle orifice 19 one end is communicated with left side oil pocket, one in several macropores uniform on the other end connection piston 13 is communicated with the other end of piston 13, and open and close type throttle orifice 19 is in normally off under the impaction state of valve block spring 22.
When the piston rod 20 of damper is by compression, piston rod 20 promotes piston 13 to left movement, oil in damper oil pocket enters the piston the other end through throttle orifice 19 and to be moved to the left along with piston and to become large cavity gradually, the flow constant of fluid under the control of throttle orifice 19, thus the motion speed of control piston reaches cover plate at the uniform velocity closes.When cover plate is opened, fluid is by the macropore compression valve block 14 on piston 13, and valve block is separated with piston thus flows into left chamber from right chamber rapidly, because throttle orifice 19 is now opened, do not have throttling, now damper does not produce resistance.
When damper does not compress, have molecule blocking throttle orifice 19, as long as suitably stretch damper, allow throttle orifice 19 be in open state, just can remove blocking.Because pulsator washing machine is that startup closed by cover plate, if cover plate cannot be closed, washing machine just cannot normally work, and anti-plugging design of the present utility model is most important to the normal work of washing machine.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
