Abstract
The invention discloses a hydraulic variable force buffer. The invention comprises an oil cylinder, a spring, a piston assembly and a sealing system, wherein the spring, the piston assembly and the sealing system are all arranged in the oil cylinder, the spring is connected with the piston assembly, and the sealing system is arranged between the piston assembly and the inner wall of the oil cylinder. Compared with the prior art, the invention has the following beneficial effects: 1. when the door is closed, the invention can dynamically generate corresponding reaction force according to the speed of the door and the magnitude of the received external force, so that the door can be closed stably without producing impact sound. 2. The invention has simple structure, easy operation and low cost.
Description
Technical field
The present invention relates to a kind of hydraulic pressure variable force snubber.
Background technology
A snubber that closes of the prior art just utilizes spring resistance to cushion, and damped coefficient is constant, and resistance can not change according to the size of outer active force and speed thereof.
The patent No. is that 200420110847.7 Chinese patent discloses a kind of " closing a snubber "; This closes a snubber and comprises installing rack and snubber body; The snubber body comprises headgear and overcoat; Headgear and overcoat are pegged graft, and headgear and overcoat also are equipped with the screens mechanism that prevents that both break away from, and the relative overcoat of headgear has specific flexible scope; Have internal thread on the headgear inwall; Also be provided with spring, turning cylinder is threaded with headgear, and turning cylinder has the external screw thread with the internal thread coupling; Insert in the sliding sleeve turning cylinder rear end; Turning cylinder sliding sleeve relatively rotates, and sliding sleeve is arranged in the overcoat, and the relative overcoat of sliding sleeve is circumferentially fixing along the sliding sleeve length direction.
Thisly close that a snubber is easy for installation, simple in structure, manufacturing cost is lower, and can make the relatively more consistent closing velocity of a maintenance within the specific limits the time closing a pressure; But because the damped coefficient of spring is constant, this structure can only be applicable to that external force changes little situation.When the speed of door or suffered external force exceed certain limit, still can produce stronger collision, produce noise.
Summary of the invention
The objective of the invention is to overcome the weak point that prior art exists, a kind of hydraulic pressure variable force snubber is provided.When closing door, the present invention dynamically produces corresponding reaction force according to the speed and the suffered external force size of door, and door can steadily be closed, and sound does not knock.
For achieving the above object, the technical scheme that the present invention taked is following:
Hydraulic pressure variable force snubber comprises oil cylinder, spring, piston component and sealing system, and spring, piston component and sealing system all are located in the oil cylinder, and spring links to each other with piston component, and sealing system then is located between piston component and the oil cylinder inner wall.
In the technique scheme, piston component is successively by spring base, the first little protruding flat circle, the second little protruding flat circle, piston, iron; Connect through a little iron between spring base, the first little protruding flat circle, the second little protruding flat circle and the piston; The little axle that spring base is provided with one section projection injects in the spring eye; The first little protruding flat circle and the second little protruding flat circle are located between spring base and the piston; One end of iron is fixed on the piston, and the other end then stretches out outside the oil cylinder.
As the improvement of technique scheme, have four breach on the spring base symmetrically; On the second little protruding flat ring support, have aperture; On piston, have through hole.
As the improvement further of technique scheme, described sealing system is made up of oil suction sponge, Type B sealing ring, little Y circle, outer retaining plug, interior cover and energy-absorbing Rubber end successively; Little Y circle is contained in the outer retaining plug; In cover Bao Ze overlay on and be located at the stretching out on the outer end of oil cylinder of iron, the end of iron is provided with the energy-absorbing Rubber end.
Held stationary when cover can make the iron motion in described; The oil that the oil suction sponge can reduce high-speed motion directly impacts Type B sealing ring and outer retaining plug; Little Y circle is contained in the outer retaining plug, can prevent leakage of oil; Type B sealing ring and outer retaining plug prevent oily earial drainage.
The energy-absorbing Rubber end is processed by rubber-like rubber, can absorb the part impact that door brings, and can guarantee that Men Buhui is clashed into damage.
Have aperture on the piston and the second little protruding flat circle; Oil can flow to the other end of oil cylinder through aperture when piston moves; If the instantaneous suffered external force of piston is bigger or speed is fast more, oil also can be big more to the active force of piston and little protruding flat circle, and this action effect is not subjected to the piston stroke position effects; Therefore this buffer can steadily cut out door dynamically based on the speed and the corresponding reaction force of suffered external force size generation of door; When external force disappeared, piston resetted under the effect of spring.
Compared with prior art, the present invention has following beneficial effect:
1. when closing door, the present invention dynamically produces corresponding reaction force according to the speed and the suffered external force size of door, and door can steadily be closed, and sound does not knock.
2. the present invention is simple in structure, and operation is with low cost easily.

The specific embodiment
Come the present invention is done further description below in conjunction with Figure of description, but the present invention's scope required for protection is not limited to the scope that embodiment is described.
As shown in Figure 1, hydraulic pressure variable force snubber of the present invention comprises oil cylinder 1, spring 2, piston component and sealing system.Piston component comprises spring base 3, little protruding flat circle 4, little protruding flat circle 12, piston 5 and iron 9.Sealing system comprises oil suction sponge 6, interior cover 11, Type B sealing ring 7, outer retaining plug 8, little Y circle 13 and energy-absorbing Rubber end 10.Spring base 3 has the little axle 32 of one section projection to inject in springs 2 holes, prevents that spring from sliding, and increases spring application life;
Like Fig. 2 and shown in Figure 3, have four breach 31 on the spring base 3, oil can flow to the other end of oil cylinder through breach, and the breach 31 of four symmetries can keep the balance of spring base 3 under fluid pressure, can not rotate vertically.Connect with a little iron 14 between the little protruding flat circle of the little protruding flat circle of spring base 3, first 4, second 12, the piston 5, can draw each other when making the piston component motion;
