Description

External damping hinge

Technical Field

The utility model relates to a damping hinge field, in particular to external damping hinge.

Background

Hinges are mechanical devices used to connect two solid bodies and allow relative rotation between them. The hinge may be constructed of a movable component or may be constructed of a foldable material. The hinges are mainly arranged on doors and windows, and more hinges are arranged on cabinets and are mainly classified into stainless steel hinges and iron hinges according to materials; the hydraulic hinge (also called damping hinge) is also provided for people to enjoy better, and is characterized in that the hydraulic hinge has a buffering function when a door body is closed, and the noise generated when the door body is closed is reduced to the greatest extent. Current attenuator and hinge integral type set up, and when the attenuator goes wrong, the hinge also can not normal use, and current attenuator arm of force is less moreover for the attenuator atress is great when using, has reduced the life of attenuator, and the damping in the current damping hinge of while all is two-way atress, all can receive the damping effect when opening and closing, has offset the sealing force of hinge. Therefore, it is necessary to invent an external damping hinge to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an external damping hinge to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an external damping hinge, includes the hinge shell, the last fixed surface of hinge shell is connected with the attenuator fixing base, the lower surface middle part fixedly connected with fixing base buckle of attenuator fixing base, the fixing base buckle sets up with the upper surface joint of hinge shell, the last fixed surface that fixed screw and hinge shell were passed through to the one end of attenuator fixing base is connected, the other end fixedly connected with attenuator of attenuator fixing base, the inside spring that is provided with of one end of hinge shell, the one end of spring is connected with the inner support, the inner support sets up in the other end inner chamber of hinge shell, the one end that the spring was kept away from to the inner support is connected with the head, the one end of head is through the other end swing joint of round pin axle and hinge shell.

Preferably, two movable grooves which are symmetrically distributed are formed in one end of the hinge shell, connectors are arranged inside the movable grooves, two ends of the spring are connected with the two connectors respectively, and one end of the inner support is fixedly connected with one of the connectors.

Preferably, the other end of the inner support is provided with a through hole, and the through hole is buckled and connected with the connecting bulge at one end of the head part.

The utility model discloses a technological effect and advantage:

the damper fixing seat is arranged on the hinge shell, the damper on the damper fixing seat effectively prevents the impact force when the door body is closed by self absorption without the damper, and simultaneously, the user experience is improved; the damper fixing seat is arranged into a detachable structure, so that the damper can be independently disassembled, assembled and replaced, the damper is assembled when the damping effect is needed, and the damper is disassembled when the damping effect is not needed, thereby being convenient for maintenance and after sale; when the damper is abnormal, the damper is disassembled, and the device can be normally used as a common hinge; compared with a common damping structure, the damping device increases the force arm, greatly reduces the stress of the damper and prolongs the service life of the damper; meanwhile, the device adopts a one-way damping structure, the damper plays a damping role when the door body is closed, a damping effect is achieved, and the damper has no damping effect when the door body is opened, so that the sealing force of the hinge is not influenced.
