Abstract
The utility model relates to a buffering hinge for door closing. The buffering hinge comprises an upper hinge case, a lower hinge case and a main shaft. The upper hinge case and the lower hinge case comprise hollow pipe portions. The hinge further comprises a main shaft fixing sleeve used for connecting the two hollow pipe portions. The main shaft fixing sleeve is hollow. The lower extension end of the main shaft extends into the main shaft fixing sleeve and located in the hollow pipe portion of the lower hinge case. The main shaft fixing sleeve is provided with a sliding groove. The lower extension end of the main shaft is provided with a spiral stroke groove. The hinge further comprises a buffering spring base, a buffering spring, a buffering spring pad and a lower end cap. The buffering spring base comprises a pad portion and an extension portion. The extension portion extends into the main shaft fixing sleeve, and the main extension portion, the main shaft fixing sleeve and the main shaft are fixed in a sliding mode. The buffering spring is arranged between the pad portion and the buffering spring pad. The buffering spring pad abuts against the lower end cap. The lower end cap is used for sealing the bottom of the hollow pipe portion of the lower hinge case of the hinge. The hinge has the advantages of preventing oil leakage and being long in service life.
Description
Technical field
The utility model relates to one and closes a buffer hinge.
Background technology
An existing buffer hinge that closes is all to utilize hydraulic pressure to realize buffering conventionally in the market, the spiral hydraulic hinge of one as described in the patent No. 201320282024.1, comprise hinge and lower jaw, upper hinge is anterior is provided with screw hydraulic device with lower jaw rear portion, screw hydraulic device upper end is provided with upper plug head, upper plug head middle part is inserted with upper plug head fixed pin shaft, screw hydraulic device lower end is provided with lower end cap, lower end cap middle part is inserted with lower end cap fixed pin shaft, and screw hydraulic device middle part is provided with inner tube; Conventionally be all such hinge that utilizes hydraulic pressure to realize buffering on the market, and the hinge of this structure can cause leakage of oil because of sealing deficiency conventionally, thereby cause the performance of hinge to weaken even damage.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provide a kind of oil-proof, the life-span is permanent closes a buffer hinge.
For achieving the above object, the utility model is that one is closed a buffer hinge, comprises shell on hinge, hinge lower casing, main shaft, and on hinge, shell and hinge lower casing include hollow tube portion, wherein, this hinge also comprises the main shaft fixed cover that two hollow tube portions are connected; Main shaft fixed cover inside is hollow, and the lower external part of main shaft stretches in main shaft fixed cover and is arranged in the hollow tube portion of hinge lower casing; On main shaft fixed cover, offer sliding tray, on the lower external part of main shaft, offer spiral stroke groove; This hinge also comprises buffer casting, buffer spring, buffer spring pad, lower end cap; Buffer casting comprises pad portion and extension, and extension stretches into and in main shaft fixed cover, is slidingtype with main shaft fixed cover and main shaft and fixes; Buffer spring is between pad portion and buffering spring pad, and buffer spring pad and lower end cap offset, and lower end cap is used for the bottom of the hollow tube portion that seals hinge lower casing.
Wherein, extension is provided with projection, and projection is arranged in sliding tray and stroke groove.
Wherein, offer pin shaft hole on extension, pin shaft hole is provided with bearing pin, and bearing pin has two external parts and is arranged in sliding tray and stroke groove.
Wherein, on described lower end cap, spiral is fixed with set screw, and one end of set screw and buffer spring pad offset for regulating the position of buffer spring pad.
Wherein, described hinge also comprises upper plug head, torque spring, torque spring seat; Upper plug head is used for the top of the hollow tube portion that seals shell on hinge, and the other end and the upper plug head of main shaft offset, and torque spring seat is positioned at the top of main shaft fixed cover, and torque spring is between torque spring seat and upper plug head.
Adopt this mechanical type principle of utilizing to replace fluid pressure type to play cushioning effect, the Leakage of having avoided hydraulic pressure to cause, thus play the life-span of having improved buffer hinge; Adopt set screw to control the height of buffer spring pad, control hinge closing velocity, more up top spring pressure is larger for screw, and door is closed slower.
