Abstract
The utility model discloses a fast-open and slow-close door with hydraulic device. At present, the manual fast-open and automatic slow-close door with simple structure and low cost is not found in the market. The utility model is designed to overcome the insufficiency of the prior art, providing a manual fast-open and automatic slow-close door. In order to solve the problems, the utility model is that: the door comprises a common door and a hydraulic device. The hydraulic device comprises a hydraulic cylinder, a piston, and a piston rod, and a spring is connected between the piston and one side of inner part of hydraulic cylinder. The piston is provided with three single-direction valves, wherein two single-direction valves have the same flow direction, and the opening pressure thereof is less than the opening pressure of the third single-direction valve. The utility model has simple structure and low cost, which can realize the manual fast opening and automatic slow closing with convenient use.
Description
Technical field
The utility model relates to a kind of door, more specifically to a kind of hydraulic means arranged can realize quick unlatching, the door of slowly closing.
Background technology
At present, many doors are arranged in public, majority gate has the function of shutting automatically after opening, but the artificial unlatching of most of doors is very slow, gruelling, the door that also has has and changes down the pass function soon, but the cost height, do not find as yet on the market now simple in structure, cost is low can realize rapid artificial unlatching, the door of slowly closing automatically.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low can realize rapid artificial unlatching, the door of slowly closing automatically.For solving the problems of the technologies described above, the utility model is by following technology:
A kind of have changing down soon of hydraulic means to close the door, and it comprises common door, hydraulic means.Hydraulic means comprises hydraulic cylinder, piston, piston rod, and oil-in, oil-out are arranged on the hydraulic cylinder, and common door links to each other with hydraulic cylinder, and piston rod links to each other with wall, and piston has spring to be connected with the inner side of hydraulic cylinder; Three one way valves are arranged in the piston, and there wherein have two one way valves to flow to be identical, and their opening pressure less than with the opening pressure of the 3rd one way valve.
Adopt above scheme, the changing down soon of hydraulic means that have that the utility model provides closed the door, concrete such beneficial effect: simple in structure, cost is low, and can realize rapid artificial unlatching, slowly close automatically, easy to use.
Description of drawings
Fig. 1 changes down the outside drawing of closing the door soon for what the utility model had a hydraulic means;
The hydraulic means sectional view that Fig. 2 has changing down soon of hydraulic means to close the door for the utility model;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Among the figure, the utility model comprises common door 1, hydraulic means 11.Hydraulic means 11 comprises hydraulic cylinder 2, piston 3, piston rod 4, and hydraulic cylinder 2 has oil-in 9, oil-out 10.Common door 1 links to each other with hydraulic cylinder 2, and piston rod 4 links to each other with wall.There is spring 5 to be connected between piston 3 and the hydraulic cylinder 2 inner sides.One way valve 6, one way valve 7, one way valve 8 are arranged in the piston 3, and one way valve 7 is identical with flowing to of one way valve 8 opposite with flow direction one way valve 6.The oil of one way valve 7 and one way valve 8 is drained the oil by oil-out 10 when changing oil.Plug seal is arranged during without hydraulic fluid port.
When opening the door, piston rod 4 promotes pistons 3 to left movement, because of the opening pressure of one way valve 7, one way valve 8 less, so fluid by piston 3 left sides to piston 3 the right flow very fast, though the resistance of spring 5 is arranged, also be easy to open the door, the speed of manually opening the door is very fast.After door was opened, external force no longer acted on the door of the present utility model, at this moment because the effect of spring 5 promotes piston 3 and moves right, the effect of one way valve 6 was arranged again, so piston 3 speed to the right is less, door of the present utility model is closed just slower automatically.
