AI Technical Summary
Existing hydraulic buffer hinges are prone to deformation at the 90-degree hinge arm position during prolonged use or installation on heavy doors, resulting in the door not being able to close completely when opening and closing.
The design employs an inclined slide guide, combined with an arc surface greater than 90 degrees. By setting an inclined slide inside the slide of the right hinge and protruding cylinders on both sides of the right arm, the inclined slide of the arm is achieved, reducing the stress on the bending position.
It effectively prevents deformation at the bending point of the door arm, improving the smoothness of opening and closing and the accuracy of closing.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to multi -functional hydraulic buffer hinge, specifically is buffer hinge with inclined slide in hinge. BACKGROUND
[0002] The middle section of the page arm of the hydraulic buffer hinge on the market is ninety degrees, and the ninety-degree page arm position is easy to deform when the force is too large during long-time use or heavy door installation, so that the left and right hinges are displaced, and the door cannot be completely closed. INVENTION CONTENTS
[0003] The utility model discloses a multifunctional hydraulic buffer hinge, which adopts an inclined slide to guide sliding of one of the page arms, and the bending surface of the middle of the two page arms is greater than ninety degrees, so that the force on the bending position of the hinge is reduced during opening and closing of the door, and the page arm is not easy to deform during long-time use.
[0004] The technical solution of the utility model is characterized in that a groove with an open top is arranged at the middle of the top of the left hinge and the right hinge, an inclined slide is arranged on the front and rear groove walls in the groove of the right hinge, the slide is inclined from left to right from high to low, and a cylinder is protruded on the front and rear sides of the right end of the right page arm, the cylinders on the front and rear sides are inserted into the slides in front of and behind the right hinge respectively, so that the right end of the right page arm slides along the slide when the hinge is opened and closed.
[0005] The bending surface of the hinge point of the middle of the left page arm and the right page arm is an arc surface greater than ninety degrees.
[0006] The utility model discloses a multifunctional hydraulic buffer hinge, which adopts an inclined slide to guide sliding of one of the page arms, and the bending surface of the middle of the two page arms is greater than ninety degrees, so that the force on the bending position of the hinge is reduced during opening and closing of the door, and the page arm is not easy to deform during long-time use.
[0007] The utility model has the advantages of reasonable structure and convenient installation, can effectively reduce the force borne by the bending position of the page arm when the hinge is opened and closed, prevent deformation of the bending position of the page arm, and make the opening and closing of the hinge more smooth and the closing precision higher. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 It is the whole three-dimensional structure schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] According to Figure 1The utility model discloses on the basis of left hinge 1, right hinge 2, hydraulic bumper 3, left page arm 4, right page arm 5, the feature is that the recess of top opening is arranged at the top middle part of left hinge 1 and right hinge 2 respectively, the inclined slide 2.1 is arranged on the front and rear groove walls in the recess of right hinge 2 respectively, the slide 2.1 is inclined from left to right from high to low, and the right end of right page arm 5 is protruded with the cylinder on the front and rear two sides respectively, and the cylinder on the front and rear two sides is inserted into the slide 2.1 of right hinge front and rear respectively, so that the right end of right page arm 5 is inclined sliding along the slide 2.1 when the hinge is opened and closed. The bending surface of the hinge joint point in the middle of left page arm 4 and right page arm 5 is the arc surface greater than ninety degrees and less than one hundred and eighty degrees.
