Abstract

The utility model discloses a vertical hydraulic control swinging door hinge, comprising a superior lobar component and an inferior lobar component. The shell of the superior lobar component is fixed with a cylinder shape cam and the inferior lobar component is an oil cylinder with a piston, a piston rod and a spring. The upper end of the piston rod extends into the cylinder shape cam of the superior lobar component and is fixed with a roller which is fastened with a cam and moves up and down along the curve of the cam. The utility model with skill structure can be automatically closed and freely adjust closing speed within a setting angle, regardless of the door being opened to which angle without any accessory. The vertical hydraulic control swinging door hinge with low cost is as convenient to be installed as the common door hinge and the opening is big bidirectionally to 93 degrees and unidirectionally to 180 degrees. When the door leaves are adjacent to wall edges, bigger indoor and outdoor action space can be obtained, so the utility model is applicable to glass doors, wooden doors and iron doors in market shops, offices, toilets and corridor smoke-preventing doors for unidirectional or bidirectional open.

Description

Vertical hydraulic control swinging door hinge

Technical field

The utility model relates to builder's finish hardware spare, particularly a kind of vertical hydraulic control swinging door hinge.

Background technology

Present swinging door hinge, though can realize closing the door automatically, but its structure is complicated, cost an arm and a leg, need additional accessory and door hinge to be used usually, as door top spring, floor spring etc., its installation must be undertaken by the professional, floor spring is installed more must be dug a 5-7 centimetre of dark melt pit,, then almost floor is dug and wear as will on floor, installing.Simultaneously, because the restriction of spring structure causes the aperture of door less,, can form obstacle the space of indoor or outdoors is dwindled when not needing automatically at closing time.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of vertical hydraulic control swinging door hinge, and it is simple in structure, and is easy for installation, and is safe in utilization and aperture is big.

The purpose of this utility model is achieved in that a kind of vertical hydraulic control swinging door hinge, comprise leaf assembly and inferior lobe assembly, it is characterized in that: described going up in the leaf assembly housing sets firmly a barrel cam, the inferior lobe assembly is an oil cylinder of establishing piston, piston rod and spring in one, piston rod upper end extends in the barrel cam of leaf assembly, sets firmly one and cam clamping and the roller that moves up and down along cam curve on this end.

The cam curve of described cam is sine curve or near sinusoidal curve.

Described roller passes through the roller pin vertical fixing in the piston rod upper end.

Described roller pin is connected in the vertically-guided groove of nextpage assembly housing.

Described piston is provided with one way valve.

Described piston or nextpage assembly housing are provided with choke valve.

The utility model structure is ingenious, in the angle of setting, no matter but which kind of angle of Men Kaizhi all auto-closing and closing speed can regulate arbitrarily, need not many annexes, expense cost is low, convenient during installation as the common door hinge, upper and lower two doors hinge need only be loaded on same axis and get final product, and aperture is big, removing two-way (positive and negative 93 °) opens the door, also can unidirectionally open, door leaf is pressed close to the wall limit, thereby obtain the bigger activity space in indoor and outdoor to 180 °.The utility model only needs to change slightly on upper and lower page or leaf assembly profile, promptly applicable to various doors, as glass door, timber, iron gates etc. such as the unidirectional or two-way arcade shop premises of opening of needs, office, washroom, corridor smoke-stop doors.

The specific embodiment

As Figure 1-3, the utility model comprises leaf assembly and inferior lobe assembly.Last leaf assembly housing upper end is by top nut 2 sealings, and for asking the sheathing 1 that also is provided with at the top attractive in appearance, enclosure interior sets firmly the cam 4 of a cylinder type, and its cam curve is sine curve or near sinusoidal curve (as shown in Figure 4).Cam 4 upper and lower upper bearing (metal) 3 and the lower bearings 8 of being respectively equipped with.Inferior lobe assembly housing upper end is provided with the connecting portion of band vertically-guided groove 18, and connecting portion is socketed in the barrel cam 4 of leaf assembly housing, and upper and lower leaf assembly is coupled together, and joint is equipped with sealing ring 9 and packing ring 10, and housing bottom is provided with lower nut 16 sealings.The cavity of inferior lobe assembly housing forms an oil cylinder, in be provided with piston 13, piston rod 17 and spring 12, piston 13 is positioned the end of piston rod 17 by back-up ring 15, spring 12 is socketed on the piston rod 17, one end props up piston 13, and the other end props up inferior lobe assembly housing inwall.Piston rod 17 upper ends extend in the barrel cam 4 of leaf assembly housing, pass through roller pin 7 vertical fixing one roller 5 on this end.Roller 5 also can roll along cam curve with barrel cam 4 clampings, and roller pin 7 runs through the vertically-guided groove 18 on piston rod 17 and the inferior lobe assembly housing, and is connected in the gathering sill 18 by the sheathed fairlead 6 in outside, thereby restriction roller 5 can only move up and down.Be provided with one way valve 14 on piston 13, the nextpage assembly housing is provided with choke valve 11, hydraulic oil can only be refluxed from choke valve 11, thereby arbitrarily control the speed of closing door by regulating choke valve.

During use, will go up the leaf assembly and be loaded on the door leaf 19, the inferior lobe assembly is loaded on the wall 20.When door was in closed condition, the roller 5 of inferior lobe assembly was in the minimum point of leaf assembly cam 4, as shown in Figure 2.When the people pushes or pulls, cam 4 is with door leaf 19 rotations, because the inferior lobe assembly is that relative fixed is static, and roller pin 7 and fairlead 6 are stuck in and can only move up and down in the vertically-guided groove 18 of inferior lobe assembly housing, therefore roller 5 rises under its vertical stress component effect with the rotation of cam 4, drive piston 13 by piston rod 17 simultaneously and promote, compression spring 12, hydraulic oil enters oil cylinder by the one way valve on the piston 13 14.The angle of opening the door is big more, and lift is also big more, their the close sinusoidal motion that is similar to.Door leaf can unidirectional or bi-directional door, shown in Fig. 5-6, can two-way positive and negative 93 ° opens the door, and also can unidirectionally open to 180 °.Let go after entering when unclamping door leaf 19, the reaction force of spring 12 promotes piston 13 and descends, and makes roller 5 be subjected to downward active force, and actuating cam 4 rotates, and its horizontal component makes door leaf 19 be subjected to turning moment and closes voluntarily.Its closing velocity is subjected to the restriction of hydraulic oil resistance, because hydraulic oil can not can only be discharged by choke valve 11 from one way valve 14 direct oil returns, can pass through to regulate choke valve 11 and arbitrarily control so close the speed of door.
