Hinge with eccentric sleeve adjustment locking device

Abstract

The invention discloses a hinge provided with an eccentric sleeve adjusting and locking device. The hinge comprises an upper hinge structure and a lower hinge structure, and each hinge structure comprises a fastening part and a hinging part which are integrally formed, wherein the two hinging parts are hinged and matched through a hinging shaft; and further, a shaft hole of the hinging part of the upper hinge structure is sleeved with an eccentric sleeve, the lower end part of the eccentric sleeve is movably inserted into and matched with the hinge shaft, the outer wall of the upper end part of the eccentric sleeve forms an inclined surface, a thread hole which is parallel to the shaft hole and is communicated with the shaft hole is formed in the position, close to the inclined surface of the upper end part of the eccentric sleeve, of the hinging part of the upper hinge structure, and a locking screw which is contacted and matched with the inclined surface of the upper end part of the eccentric sleeve in a separation and reunion manner is arranged in the thread hole. The hinge has the benefits that an eccentric sleeve structure is improved, parts of an eccentric sleeve adjusting structure are reduced, the operation is convenient and easy, the adjusting and the locking are performed in the same direction, the elastic positioning and the rigid locking are mutually matched, and the hinge is durable, safe and reliable.

Description

technical field [0001] The invention relates to a hinge, which belongs to the technical field of hinge products, in particular to a hinge with an eccentric sleeve adjusting and locking device. Background technique [0002] For a long time, hinges have been widely used in various door leaf fields. In the field of swing door hinge technology, in order to compensate for errors in door leaf or door and window manufacturing, in order to obtain a uniform door frame gap and good sealing performance, the hinge is generally required to have adjustment functions in multiple directions. Among them, the adjustment in the left and right direction of the door leaf is mainly to adjust the gap between the door frame and the left and right sides of the door leaf, and the adjustment in the direction of the inside and outside of the door leaf is mainly to adjust the sealing pressure of the door frame and the door leaf. These two adjustment methods are generally in the hinge. It is carried out...

Problems solved by technology

However, judging from the current hinge field, the existing eccentric sleeve structures are relatively complex, and there are defects such as inconvenient adjustment or unreliable locking. The eccentric sleeve structure also has adverse effects on the hinge structure
