Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, in particular to a wooden door hinge. Background Art

[0002] The hinge of a wooden door is a connecting piece set between the wooden door and the door frame. Although the existing wooden door hinge can meet the basic requirements of connecting the wooden door and the door frame, and can flexibly adjust the connection structure of the hinge through the adjustment structure, thereby eliminating the hidden danger of not being able to smoothly install the wooden door due to slight errors in measurement, the lateral adjustment structure used is often not provided with a guide structure, so that the hinge will easily have a tendency to rotate and deviate relative to the connection structure during operation, which will easily cause the connection structure to loosen and wear, which will bring inconvenience to people's use and will also affect the service life of the hinge.

[0003] For example, the utility model with announcement number CN 207063759 U discloses an adjustable wooden door hinge. In the technical solution of this patent, the adjustment page is mainly installed on the door leaf by self-tapping screws during installation, and the adjustment page is fixed to the upper rotating page by screws. Since the installation hole is an adjustable waist-shaped long adjustment hole, when it needs to be adjusted left and right, it is only necessary to loosen the screws, adjust the door leaf to the corresponding position and then tighten it. However, since there is no guide structure between the upper rotating page and the fixed adjustment page, the flexible fixation of the fixed adjustment page and the upper rotating page is achieved only by passing the screws through the waist-shaped adjustment hole. Therefore, during the operation of the hinge, the screws are easily affected by the deflection force, causing the screws to loosen and wear, which will bring great inconvenience to people's use. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a wooden door hinge, which can not only meet the basic needs of connecting and fixing the wooden door and the door frame, but also enable the user to flexibly and conveniently adjust the hinge vertically and horizontally, thereby more fully meeting people's usage needs, and can prevent the hinge from loosening and wearing easily through the guide structure, thereby extending the service life of the hinge and better meeting people's usage needs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a wooden door hinge, comprising a lower hinge and an upper hinge rotatably connected to the lower hinge through a connecting shaft, the side end of the lower hinge is provided with a first connecting groove, a first fixing plate is vertically slidably arranged in the first connecting groove, a first connecting bolt for screwing and fixing the first fixing plate is provided on the first connecting groove, a plurality of first threaded connecting holes matched with the first connecting bolt are provided on the first fixing plate, and a first fixing bolt for screwing and fixing to the door frame is provided on the first fixing plate; a second connecting groove is provided at the side end of the upper hinge, a second fixing plate is horizontally slidably arranged at the side end of the second connecting groove, a second connecting bolt for screwing and fixing the second fixing plate is provided on the second connecting groove, a second threaded connecting hole matched with the second connecting bolt is provided on the second fixing plate, and a second fixing bolt for screwing and fixing the wooden door is also provided on the second fixing plate.
