Abstract
The utility model belongs to a hardware field, mainly relating to a civil and an industrial hinges. The utility model is primarily composed of a shaft, a positioning ball on the upper part of the shaft, foldouts on the two heads, and a return spring and an adjusting mat arranged on the bottom of the shaft. A rotation shaft eccentricity is arranged in the oil cylinder, a slot is arranged on the rotation shaft, two sealed strips are arranged in slots on the both sides of the rotation shaft in 180 EGD, and a right eccentric cover and a right eccentric cover are respectively arranged on the two ends of a left and a right ends. The utility model has the advantages of small volume and simple structure, and can use in the method that the oil cylinder as a main foldout matches with a self-off and positioning device as an auxiliary foldout. The utility model is suitable for hospital, school, hotel, scientific research institutions, institution, and resident home-use which all have the characteristics of quiet and safety, and can be fixed on a position.
Description
The invention belongs to hardware products, relates generally to civilian or industrial hinge.
The civilian folding of prior art is better simply hinge form, when door switch, with the size of exerting oneself, adjusts the switch speed of door.But when firmly too big, door is closed rapidly or is opened rapidly, is easy to cause accident.In addition, can not close automatically and locate automatically in a certain position.
The purpose of this utility model provides a kind of switch speed of adjusting door, the door butt that can close automatically and can locate automatically in a certain position.
The utility model is by the place kick on rotating shaft, rotating shaft top, two folding, is installed in the return spring and the adjusting pad of rotating shaft bottom, rotating shaft off-centre is installed in the oil cylinder, the rotating shaft both sides are provided with groove, diaphragm seal is in 180 ° of grooves that are installed in the rotating shaft both sides, at the two ends, the left and right sides of oil cylinder left eccentric cover and right eccentric cover is installed respectively.
In the groove of rotating shaft spring is installed, the spring in diaphragm seal one end and the groove contacts, and the other end contacts with the inwall of oil cylinder.In in-oil cylinder rotating shaft, offer the stairstepping through hole, have a ball to contact in the through hole with the cascaded surface of through hole.Through hole is set in left eccentric cover communicates, a ball is installed in the through hole is contacted with cascaded surface in the through hole with A, B two Room of oil cylinder, the spring one end in contact ball that in through hole, is provided with, the other end contacts with the inner face of screw.
The utility model can control gate switch and swing speed, be applicable to require peace and quiet, safety, location very much hospital, institute, machine-operated office, scientific research institutions, hotel and family's use.Characteristics such as it is little to the utlity model has volume, simple in structure can be arranged apart, can snubber be main folding, uses to close and to orientate as secondary folding pairing certainly.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model A-A sectional view.
Fig. 3 is the structural representation of the utility model left side eccentric cover.
Among the figure: 1 place kick, 2 two foldings, 3 left eccentric covers, 4 rotating shafts, 5 oil cylinders, 6 diaphragm seals, 7 right eccentric covers, 8 return springs, 9 adjusting pads, 10 diaphragm seals, 11 springs, 12 springs, 13 balls, 14 balls, 15 springs, 16 screws
In the groove of the rotating shaft 4 in the tubulose oil cylinder 5, be 180 ° (or other angle) 2 (or several pieces) diaphragm seals are installed, spring 11 and spring 12 are installed in the sheet back-trough of diaphragm seal 6 and diaphragm seal 10, left side eccentric cover 3 and right eccentric cover 7 all have sealing ring with the contact surface of oil cylinder 5, rotating shaft 4 is stretched out eccentric cover and is connected with two folding 2, oil cylinder 5 links to each other with middle folding, fill with hydraulic oil in the oil cylinder, diaphragm seal in the rotating shaft 3 is separated into two (or more than two) A with oil cylinder 5, the B grease chamber, when door is opened, driving rotating shaft 4 rotates, hydraulic oil part in the oil cylinder 5 flows to the A chamber by the gap of diaphragm seal 6 and diaphragm seal 10 and inboard wall of cylinder block from the B chamber, a part of in addition hydraulic oil is from the stairstepping through hole of rotating shaft 4, and the contact surface of pushing ball 13 and through hole open makes oil flow to the A chamber from the B chamber.When door reached 90 °, place kick 1 pushed place kick 1 in the groove in two folding 2 under the effect of spring force, makes door location automatically.When door is closed, a hydraulic oil part flows to the B chamber by the gap of diaphragm seal 6,10 and inboard wall of cylinder block from the A chamber, another part is by ball 14, spring 15 and screw 16 in the left eccentric cover 3, flow into the B chamber from the A chamber, how much what control screw 16 entered is the pressure size of spring, can control the flow size.Thereby the speed of closing the door of control gate.In addition, screw and unclamp adjusting pad 9, can control the torque magnitude of return spring 8, but the also closing velocity of control gate.
