Embodiment
Fig. 1 is the utility model buffering speed change gear blast embodiment schematic representation.Fig. 2 is the utility model buffering speed change gear assembling embodiment schematic representation.Describe below in conjunction with Fig. 1 and Fig. 2.
As shown in Figure 2, the buffering speed change gear comprises: a piston rod 1, and piston rod 1 bottom is connected with a piston 7, and piston rod 1 the other end can be connected on the mechanical motion object that any needs cushion, on furniture office object;
One body 10, piston 7 is positioned at the tube chamber of body 10 upper ends, has successively first isolating device, the elastic element that links to each other in the tube chamber of body 10 lower ends and is used for first air locking of sealed tube body 10 lower ends.
As depicted in figs. 1 and 2, first isolating device comprises the 3rd seal ring 12, seal ring baffle plate 13; Elastic element is a spring; First air locking is a back plug 15 of closed tube lower end.
Be full of buffer solution 11 between the intraluminal seal ring 12 of intraluminal piston 7 in body 10 upper ends and lower end, as damping oil.
During specific implementation, piston 7 stops up body 10 upper ends, pulls out or be pressed into the piston rod 1 that links to each other with piston 7, and damping oil can cushion pulling force or pressure, and the elastic element of dependence lower end compresses or eject, thus the impact force that can slow down piston rod.
If piston rod 1 only lower end connects a piston 7, though also can realize buffering, piston rod 1 and body 10 upper ends are because fixing, rock in the time of may pulling out or be pressed into, therefore, as Fig. 1 and Fig. 2 embodiment, the piston rod 1 and the tube chamber joint of body 10 upper ends are optimized, particularly:
Suit second air locking and second isolating device successively on the piston rod 1, and be positioned at piston 7 upsides.Wherein, second air locking comprises preceding gag 2, preceding plug 3, first seal ring, second seal ring 5 that connects successively; Second isolating device is a seal ring baffle plate 6.
Because second air locking and second isolating device are sleeved on the piston rod 1, therefore coaxial with piston rod 1, piston rod 1 can move in preceding gag 2, preceding plug 3, first seal ring 4, second seal ring 5, seal ring baffle plate 6, as shown in Figure 5 and Figure 6.Wherein preceding gag 2, preceding plug 3 are socketed in body 10 upper ends, and seal ring baffle plate 6 is positioned at the tube chamber of body 10 upper ends.
Can find out that by Fig. 1 and Fig. 2 piston 7 is to be connected piston rod 1 bottom, therefore, the moving of piston rod 1, as pull out or be pressed into and can drive piston motion, and preceding gag 2, preceding plug 3 fixed covers are in body 10 upper-end front.
3 fens two-part of preceding plug, the upper end external diameter of preceding plug 3 is greater than lumen diameter, the lower end external diameter equals lumen diameter, therefore plug 3 upper ends are stuck in outside, body 10 upper end before, fix, the lower end is then stretched in the tube chamber of body 10 upper ends, and is inserted in the inside, lower end of preceding plug 3 by first seal ring 4, second seal ring 5, seal ring baffle plate 6 external diameters are identical with the lumen diameter of body, realize the airtight of body 10 upper ends.
As Fig. 1 and Fig. 2, piston 7 downsides also are connected with piston sleeve 8 and piston sleeve fixed plate 9 in turn, and wherein, piston sleeve 8 external diameters are slightly less than body 10 lumen diameters, micro-gap G as shown in Figure 4.
As shown in Figure 3, piston 7 is provided with groove, therefore, when piston rod 1 is pressed into, damping oil 11 can overflow by the micro-gap of Fig. 4 piston sleeve 8 with lumen diameter, and overflow by the groove micro-gap of piston shown in Figure 37 inside, the damping oil flow that overflows by control changes piston 7 stressed sizes.If want to increase the spill-out of damping oil, piston 7 external diameters can be set be slightly less than lumen diameter, the internal recess of piston 7 etc. can also be set simultaneously.
Introduce down assembling process below by Fig. 1 and Fig. 2:
One. seal ring 12. seal ring baffle plates 13. springs 14 body 10 1 ends of packing into, as Fig. 1 lower end, the back plug 15 of packing into, again with body 10 lower ends and back plug 15 by the ultrasound oil sealing.
Two. from body 10 other ends, pour into damping oil 11 as body 10 upper ends from Fig. 1 and Fig. 2.
Three. plug 3. first seal rings 4. second seal rings 5. seal ring baffle plates 6 before the gag 2. before the piston rod 1 coaxial insertion, and connect piston 7. piston sleeves 8. piston sleeve fixed plates 9 in piston rod 1 lower end with groove, piston rod 1 is connected above-mentioned device after formation group body insert again in body 10 tube chambers of filling damping oil.
Four. with preceding gag 2, preceding plug 3 and body 10 upper end ultrasound oil sealings.
The explanation that makes an explanation of state when piston rod 1 being pressed into below by Fig. 3, Fig. 4 and Fig. 6.Damping oil overflowed embodiment's schematic representation when wherein Fig. 3 was pressed into for the piston rod of the utility model buffering speed change gear, the local enlarged diagram that internal diameter of tube body and piston sleeve external diameter damping oil overflowed when the piston rod that Fig. 4 cushions speed change gear for the utility model was pressed into.Fig. 6 is pressed into state embodiment schematic representation for the utility model buffering speed change gear.
One. when piston rod 1 was pressed into, after damping oil 11 impact pistons cover 8 was close to piston 7, damping oil 11 was overflowed by piston 7 internal recess micro-gap E, produces resistance, as shown in Figure 3.On the other hand, have micro-gap G between body 10 internal diameters and piston sleeve 8 external diameters, damping oil 11 overflows the generation resistance, as shown in Figure 4.By control damping oil flow the stressed size of piston is changed.
Two .. such as Fig. 6, when piston rod 1 is pressed into, damping oil 11 overflows by micro-gap G and the micro-gap E as Fig. 3 and Fig. 4, but downward pressure seal ring 12 makes with seal ring baffle plate 13 and shrinks back because damping oil is stressed, the D seal ring 12 and the seal ring baffle plate 13 damped oil that are Fig. 6 are to pressing down, vacate the damping oil space, spring 10 compressions.
Fig. 5 pulls out state embodiment schematic representation for the utility model buffering speed change gear.As shown in Figure 5, when piston rod 1 was pulled out, damping oil pressure disappeared, and the compressive force that discharges by spring 14 resets seal ring 12 and seal ring baffle plate 13, promptly among Fig. 5 shown in the B.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
