Hydraulic damper is to move to suppress the influence of pipeline or equipment periodic property load and shock loading by special construction valve control hydraulic cylinder piston.Chinese patent CN 2514084Y discloses a kind of hydraulic damping device, and comprise a liquid seal cylinder, have the piston of through hole, and the piston rod that connects with piston etc.In the liquid seal cylinder fluid is housed.When the door of rapid movement bumped against on the piston rod, the direction that driven plunger is closed along door was moved, and then the liquid in the compression cylinder.Because liquid will flow to the opposite side of piston along aperture in the Incoercibility of liquid, cylinder, this will produce damping action and hinder closing of door.Above-mentioned hydraulic damper exists damping not regulate, and cylinder body is had higher sealing requirements.In case the generation oil liquid leakage, hydraulic damper will lose efficacy.It can only produce damping the mentality of designing of this patent decision simultaneously when door is closed, for the door of opening rapidly, this damper can not cut any ice.
The operating principle of air pressure damper is similar to hydraulic damper, but what be to use is gas medium.There is not the problem of leak of liquid in the air pressure damper.Chinese patent CN 1425841A discloses a kind of air-supported shock absorber.It comprises the cylinder of one section opening and can form at the piston that has seal that be along the longitudinal movement on the cylinder and be connected on the push rod.Because the size in hole is a definite value, so the damping that this shock absorber produces just no longer can be regulated after dispatching from the factory, its damping also is unidirectional simultaneously, only when door is closed, works; And when opening the door action, can't realize damping.
In addition, more than the actual configuration of two kinds of dampers all complicated, and then reduced functional reliability.
Summary of the invention
The objective of the invention is deficiency, provide a kind of and can regulate damping, can when the door body is closed or opened, all possess damping function again to existing buffer technology, and the bidirectional buffer of the Adjustable Damping of simple in structure, reliable operation.
For achieving the above object, the present invention realizes through following technical scheme:
The present invention is provided with cylinder block, one-way exhaust valve, breather cheek valve, piston and connecting rod;
It is inboard that cylinder block is fixed in outside doorframe; One-way exhaust valve and breather cheek valve all are located at the cylinder block rear end, and one-way exhaust valve and breather cheek valve are adjustable in pressure, and piston and cylinder block bore seal are slidingly matched; Connecting rod one end and piston hinge, the connecting rod other end is hinged with outside door leaf.
Said cylinder block both sides preferably are provided with mount pad, and mount pad fixedly connected to the inner side through securing member and outside doorframe.
Compare with prior art, the present invention has following outstanding advantage:
Because the present invention is the air-cylinder type damping unit, can avoid existing hydraulic damper problem, the problem includes: the nonadjustable problem of oil liquid leakage problem and damping; Regulate because one-way exhaust valve and breather cheek valve can carry out pressure, therefore avoided the uncontrollable problem of air pressure damper damping, and realized the bidirectional damper effect of snubber simultaneously.The present invention not have especially strict requirement for sealing, and structure is very simple, manipulates very conveniently, and work very reliably.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
In Fig. 1, respectively be labeled as: 1-regulates bolt, the 2-spring, and the 3-cylinder block, the 4-Metal Ball, 5-piston 6-connecting rod, the 7-door leaf, the 8-door-hinge, the 9-fixture, the 10-mount pad, the 11-sealing ring, the 12-spring, the 13-Metal Ball, 14-regulates bolt.
The specific embodiment
Referring to Fig. 1, the embodiment of the invention is provided with cylinder block 3, one-way exhaust valve (constituting by regulating bolt 1, spring 2 and Metal Ball 4), breather cheek valve (constituting by regulating bolt 14, spring 12 and Metal Ball 13), piston 5 and connecting rod 6;
It is inboard that cylinder block 3 is fixed in outside doorframe (not shown); One-way exhaust valve and breather cheek valve all are located at cylinder block 3 rear ends; One-way exhaust valve and breather cheek valve are adjustable in pressure, and piston 5 is provided with sealing ring 11, and piston 5 is slidingly matched with cylinder block 3 bore seal; Connecting rod 6 one ends and piston 5 are hinged, and connecting rod 6 other ends are hinged with the fixture of being located on the outside door leaf 79.Label 8 is the rotation reference axis of door leaf 7 (being door-hinge).Mount pad 10 is located at cylinder block 3 both sides.
Through regulating bolt 1 and the decrement of regulating bolt 14 change springs, can adjust the damping that reaches suitable.
Operating principle explanation is as follows: as shown in Figure 1, and when door is closed, the slider-crank mechanism promotion piston of forming by door leaf 7, connecting rod 6 and piston 55 lateral movement of turning left, the closed gas that compressed gas cylinder body 3 is interior.The volume of airtight gas will diminish, and its pressure will increase, and the direction of motion that receives force direction and piston that piston is total is opposite, and piston is retarded motion, and then hinder closing of door.In the compressed process of sealing gas, by the exhaust check valve that bolt 1, spring 2 and Metal Ball 4 are formed, the pressure that Metal Ball is turned left by cylinder block 3 gases on the one hand, the effect of making a concerted effort that turned right by atmospheric pressure and spring 2 on the one hand.Increase gradually (volume reduces gradually) along with the cylinder block internal gas pressure; The pressure of turning left greater than turn right make a concerted effort the time, sealing gas will back down Metal Ball, a part of gas will spew out in the atmosphere; Gaseous mass reduces in the cylinder block; Air pressure will reduce simultaneously, and then make the resistance force diminishes of closed gas to piston 5, and spring 2 promotes Metal Ball with valve closes simultaneously.Along with gas volume in the cylinder block 3 further reduces, closed gas and exhaust check valve that piston 5, quality reduce will average out under new condition.Reasonably regulate the tension force situation of exhaust valve spring 2, damping that can adjustment doors does not influence normally closing of door.
When opening the door, the slider-crank mechanism pulling piston of forming by door leaf 7, connecting rod 6 and piston 55 motion of turning right, cylinder block 3 interior gas volumes will increase; Pressure will reduce; The direction of motion that receives force direction and piston that piston is total is opposite, and piston is retarded motion, and then hinders opening of door.The breather check valve that consideration is made up of bolt 14, spring 12 and Metal Ball 13, Metal Ball receive the resultant pressure that gases and spring 12 are turned left in the cylinder block 3 on the one hand, and one side receives the effect of the pressure that atmospheric pressure turns right.Along with cylinder block 3 internal gas pressures reduce gradually, atmospheric pressure will back down Metal Ball, and a part of gas will get in the sealing cylinder; Gaseous mass increases; Pressure increases, and then makes the resistance force diminishes of closed gas to piston 5, and spring 12 promotes Metal Ball with valve closes with cylinder pressure simultaneously.Along with gaseous mass and volume in the cylinder block 3 further increase, gas and breather check valve will average out under new condition in piston 5, the cylinder block 3.Reasonably regulate the tension force size of inlet valve spring 12, damping that can adjustment doors does not influence normally opening of door.
