The novel hydraulic cushion cylinder has the benefit effects that 1) the novel hydraulic cushion cylinder is simple in structure, and low in production cost, and the market competitiveness can be improved; 2) the hydraulic oil damping stroke can be prolonged, and the oil liquid running speed can be accelerated, so that a buffer bar is even in moving speed, and stable to move; and 3) the cushion hydraulic oil flows out of the side wall of the piston ring, so that the hydraulic oil is directly and quickly sprayed out of the end of the piston ring to be impacted and mixed with the oil liquid in the cylinder at a high speed in the prior art can be avoided, the oil-gas mixing degree can be reduced, and the running stability of the buffer bar can be improved.
Description
Technical field
The utility model relates to a kind of hydro-cushion hinge accessory, specifically is a kind of novel hydraulic cushion dashpot.
Background technique
In furniture industry, generally use hinge to connect cabinet door and cabinet, this hinge is provided with spring assembly, makes the effect through spring after unlatching of cabinet door, automatically replies original position, removes the trouble that hinged door hinge in the past needs magnetic or latch to fix from, and is easy to use.But this articulated manner is because the spring-back force effect of spring, in that the collision of cabinet door and cabinet can take place at closing time, sends huge sound, even breaks putting bad or breakable article in the cabinet, causes damage and danger.In order to address this problem, people develop hydro-cushion hinge, and this kind hydro-cushion hinge because hydraulic buffer cylinder plays buffer function, reduces the spring-back force of spring at closing time greatly, reduce the speed of closing the door simultaneously.Require the inside indentation rate request of cushion dashpot fast in the sort buffer hinge; Thereby make that the speed of opening the door is unaffected; And require the cushion dashpot movement velocity slow at closing time, and remain a constant speed and accomplish the action of closing the door, avoid furniture door and cabinet to send sound because of collision; And alleviate vibrations to the cabinet door.But this kind hydro-cushion hinge structure is complicated, and production technology is loaded down with trivial details, and quality is unstable; Say so more specifically, because hydraulic buffer cylinder has certain cushion stroke restriction, so the hydraulic oil in the cylinder designs according to its stroke; In long-term experiment, the applicant finds, when cushion dashpot kicking motion process speed is not uniform; But by putting fast operation slowly, so during to stroke terminal, cabinet door and cabinet still have the sound generation of bump.
The model utility content
The purpose of the utility model is to provide a kind of simple and reasonable to the existing defective of existing known technology product, and cost of production is low, and buffer speed is even, the novel hydraulic cushion dashpot of long service life.
The purpose of the utility model is achieved in that a kind of novel hydraulic cushion dashpot, comprises cylinder body, piston rod; Seal with annular groove spare, and be located at the piston assembly on piston rod top, it is characterized in that: described piston assembly comprises positioning strip; Piston ring; Be located at the seal groove on the piston ring excircle, described seal groove is provided with the oil diverting port that several and piston ring upper-end surface connect, and also is provided with the damping hole that runs through its upper and lower end face on the described piston ring; Piston ring the lower end surface be provided with the circular arc plate-like oil guide slot that connects this damping hole, oil guide slot is stamped oil pressing plate outward.
The opening shape groove that described oil guide slot caves inward for the piston ring lower end surface.
Described oil guide slot is circular arc coiling shape and is located at the piston ring lower end surface, and oil guide slot one end connects damping hole, and the other end and piston ring sidewall connect and form unloading port.
Be provided with sealing O type circle in the described seal groove.
Described piston rod is the step axle, and after piston ring placed the small end of piston rod, oil pressing plate pressed in the lower end surface of piston ring and with piston rod and is fastenedly connected.
The beneficial effect of the utility model is: 1) simple in structure, cost of production is low, improves the market competitiveness.2) lengthening hydraulic oil damping stroke, and fluid movement velocity, the buffer bar movement velocity that makes is even, operates steadily.3) buffering hydraulic oil flows out from the sidewall of piston ring, reduces firing rate and pressure.Avoid in the conventional art hydraulic oil directly to spray fast and mixes minimizing oil gas mixability, lifting buffer bar operation stability with cylinder inner fluid high-speed impact by the piston ring end.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.A kind of novel hydraulic cushion dashpot comprises cylinder body 1, piston rod 6; Seal with annular groove spare 7; And be located at the piston assembly on piston rod top, it is characterized in that: described piston assembly comprises piston ring 3, is located at positioning strip 33 and seal groove 31 on the piston ring excircle; Described seal groove 31 is provided with the oil diverting port 32 that several and piston ring 3 upper-end surfaces connect; Also be provided with the damping hole 4 that runs through its upper and lower end face on the described piston ring 3, piston ring the lower end surface be provided with the circular arc plate-like oil guide slot 41 that connects this damping hole 4, the oil guide slot 41 outer oil pressing plates 2 that are stamped.
The opening shape groove that described oil guide slot 41 caves inward for the piston ring lower end surface.
Described oil guide slot 41 is circular arc coiling shape and is located at the piston ring lower end surface, and oil guide slot 41 1 ends connect damping hole 4, and the other end and piston ring sidewall connect and form unloading port 42.
Be provided with sealing O type circle 5 in the described seal groove 31.
Described piston rod 6 is the step axle, and after piston ring 3 placed the small end of piston rod, oil pressing plate 2 pressed in the lower end surface of piston ring 3 and with piston rod 6 and is fastenedly connected.
Working principle: in the utility model, when piston rod inwardly moved, the hydraulic oil that is positioned at the lower end flowed toward the upper end; So hydraulic oil promotes O RunddichtringO 5 from the bottom up, because seal ring 5 is positioned at seal groove 31, and seal groove 31 is provided with several and the oil diverting port 32 of piston ring 3 upper-end surfaces perforation; So under the pressure of hydraulic oil; Deformation takes place in seal ring 5 at oil diverting port 32 places, thereby loses seal action, and hydraulic oil flows into the upper end of cushion dashpot from oil diverting port 32.Thereby can use less power but can buffer bar moved from top to bottom, thereby satisfy the requirement that the buffering hinge can be opened the cabinet door fast.When needs at closing time, need oil hydraulic cylinder to play buffer function, so when piston moved upward, seal ring was close to seal groove 31, the gap between seal ring 5 sealing seal rings and cylinder body is so hydraulic oil can only flow to the cushion dashpot below through damping hole 4.Because damping hole is less, has limited the flow of hydraulic oil, so can play preliminary buffer function.Hydraulic oil gets into oil guide slot 41 through behind the damping hole, because oil guide slot 41 is narrow and length is longer; So hydraulic oil has bigger resistance when flowing; By further maximum speed limit and flow, can continue uniform damping piston motion, steadily close an effect uniformly thereby reach hinge.Moreover buffering hydraulic oil flows out reduction firing rate and pressure from the unloading port 42 of the sidewall of piston ring 3.Avoid in the conventional art hydraulic oil directly to spray fast and mixes minimizing oil gas mixability, lifting buffer bar operation stability with cylinder inner fluid high-speed impact by the piston ring end.
