Description
Technical Field
The utility model relates to a door and window accessory technical field especially relates to a hinge structure of adjustable elasticity after installation.
Background
The door hinge is a device that allows the door to be naturally and smoothly rotated to open and close. The door hinge generally comprises a hinge seat and a hinge body, wherein one end of the hinge body is connected with a door frame through a mandrel, the other end of the hinge body is connected with a door leaf, the hinge body is divided into two sections, one section is connected with the mandrel, the other section is connected with the door leaf, the two sections of hinge bodies are connected into a whole through a connecting plate, and a door gap adjusting hole is formed in the connecting plate. Because the hinge body is divided into two sections and is connected into a whole through the connecting plate, the door leaf can be detached for repair after the connecting plate is detached.
Traditional hinge is mostly through the fix with screw when fixed, and the time is of a specified duration easily not hard up after the fix with screw, and the door plant just drops easily, and reciprocal hole diameter behind the dismantlement screw enlarges, and the door plant after the installation is not hard up, just drops easily after opening and shutting the activity for a long time again, and many accidents all are consequently leading to the fact, consequently have the modified necessity.
SUMMERY OF THE UTILITY MODEL
The utility model provides a door hinge structure which can be easily installed and disassembled, reduces the damage to a door frame and the like, and is more firmly fixed and can adjust the tightness after being installed; the problem of exist among the prior art traditional fixed mode used repeatedly damage door plant, time is not hard up easily for a long time and rocks, has the technical problem of potential safety hazard.
The above technical problem of the utility model is solved through following technical scheme: the utility model provides a but door hinge structure of adjustable elasticity after installation, includes the installation base, rotates on the installation base and is equipped with the rotation seat, rotation seat on one side rotate and be equipped with the axis of rotation, evenly be equipped with the first regulation tooth of a plurality of cockscomb structure range on the lateral wall of axis of rotation, the axis of rotation top is equipped with the adjusting nut who is used for adjusting the axis of rotation, is equipped with the second on the opposite side of rotation seat and adjusts the tooth. The installation pedestal mounting is on the door frame, it installs the rotation seat to rotate on the installation pedestal, rotate the seat and install on the door, the installation pedestal makes up into the hinge with rotating the seat and rotates the door and install on the door frame, when rotating the seat during installation, open the apron earlier, then rotate adjusting nut, adjusting nut drives the axis of rotation and fixed axle rotation, adjust the rotation of first regulation tooth to the one side that is close to the rotation seat, then will rotate the seat and install in the mounting groove of waiting to install, then rotate adjusting nut rotation 180 degrees once more, along with adjusting nut's rotation, the axis of rotation rotates to the one side of keeping away from the rotation seat with first regulation tooth, the axis of rotation rotates the inner wall extrusion of back first regulation tooth and mounting groove, the reaction force that first regulation tooth and mounting groove inner wall extrusion produced can promote to rotate the seat and move to the one side that is close to the second regulation groove, the second adjusts the inner wall extrusion of tooth and mounting groove opposite side, first regulation tooth and the inner wall of second regulation tooth expand to prop to the mounting groove to both sides, make the more firm of rotating the seat installation, the same reason, if want to take out once more rotate the rotation seat and only need to rotate 180 degrees once more, the rotation of rotation and rotate the regulation nut once more, get back to the initial state, the mounting groove, the extrusion seat disappears.
Preferably, a fixed shaft is eccentrically arranged in the middle of the rotating shaft and is rotatably arranged in the rotating seat. The fixed shaft is arranged in the rotating seat, two ends of the fixed shaft are eccentrically connected with the rotating shaft, and the fixed shaft is used for fixing the rotating shaft on the outer side of the rotating seat and rotating and adjusting along with the rotating shaft.
Preferably, the center of the fixed shaft and the center of the adjusting nut are on the same vertical line. Because the end of the rotating shaft is fixed on the adjusting nut, when the adjusting nut is rotated, the rotating shaft eccentrically rotates around the circle center of the adjusting nut, so that the fixed shaft and the adjusting nut are concentric shafts, and the rotating shaft can be more stable when eccentrically rotates.
Preferably, the first adjusting tooth and the second adjusting tooth are both arc-shaped teeth with sharp outer corners. The sharp angle of the outer side of the first adjusting tooth and the outer side of the second adjusting tooth is slightly embedded into the inner wall of the mounting groove to increase friction, so that the rotating plate is fixed firmly, and meanwhile, the arc-shaped teeth are smoother during rotation in the groove.
Preferably, the second adjusting tooth and the first adjusting tooth are made of metal materials. The first adjusting teeth and the second adjusting teeth rotate under the extrusion state of the inner wall of the groove, and the first adjusting teeth and the second adjusting teeth made of other softer materials are easy to break off when extruding with the groove.
Preferably, the adjusting nut and the fixed shaft are eccentrically connected to the rotating shaft at the side far away from the rotating seat. Adjusting nut drives the fixed axle and rotates with the axis of rotation, first regulation tooth is located the one side that is close to the rotation seat during initial condition, then rotate adjusting nut and rotate first regulation tooth to the opposite side, adjusting nut and fixed axle eccentric connection are in the axis of rotation of keeping away from rotation seat one side, when adjusting nut rotates the drive and rotates the rotation axial opposite side and rotate like this, the axis of rotation volume can be to keeping away from rotation seat one side and remove, with the inner wall extrusion of treating the mounting groove, first regulation tooth embedded groove inner wall simultaneously, make the rotation seat remove to second regulation tooth one side, the fixed of rotating the seat is more firm like this.
Preferably, the adjusting nut is covered by a cover plate. The effect of apron is to cover adjusting nut, prevents that adjusting nut is touched by the mistake under the exogenic action, leads to rotating the seat fixed ability and descends and cause danger.
Therefore, the utility model discloses an adjustable elasticity's of installation back hinge structure possesses following advantage: convenient to detach or installation door angle structure, easy operation, and repetitious usage is less to damage such as door plant door frame, can use in multiple similar occasion, and is fixed more firmly to door plant etc..
