Description
Technical Field
[0001] The utility model relates to a hinge or a pivot with a special structure, in particular to a special hinge for a tile and stone invisible door. Background Art
[0002] Hinge, also known as hinge, is formally called hinge. It is usually composed of two folding parts, and is a component that connects two parts of an object and enables it to move. Ordinary hinges are used for cabinet doors, windows, doors, etc. The top and bottom axis hinges used generally have no adjustment function. During installation, the installer has high requirements for size control, so the installation efficiency is low. Once the installation is not in place, the later adjustment is very troublesome; for this reason, adjustable top and bottom axis hinges have also appeared in the market; For example, the utility model with announcement number CN201024809Y discloses an adjustable top and bottom axis hinge, including an upper hinge arm of a door cover, an upper hinge arm of a door leaf, a lower hinge arm of a door cover, a lower hinge arm of a door leaf, and upper and lower shafts, and a cylindrical shaft sleeve with threads inside and outside, and one end face of the shaft sleeve is welded and fixed to the upper hinge arm of the door leaf and the lower hinge arm of the door leaf; the outer sides of the upper shaft and the lower shaft are threaded, and the end faces are provided with inner hexagonal holes, A locking nut is respectively arranged below the upper shaft and above the lower shaft. The locking nut has the same external thread as the upper and lower shafts, and its end face is also provided with an inner hexagonal hole. The upper and lower shafts are respectively coaxially installed in the shaft sleeve with a locking nut. The utility model can conveniently implement fine adjustment of the upper and lower gaps between the door leaf and the door frame with an inner hexagonal wrench without removing the door leaf. The hinge is interchangeable for left and right doors, adopts lower load-bearing, is safe and reliable, and the hinge can be disassembled as a whole, which is convenient to install and use.
[0003] The above structure adjusts the gap between the door leaf and the door frame by adjusting the position between the door leaf hinge arm and the door leaf. When adjusting, the connection between the door leaf hinge arm and the door leaf needs to be loosened, which is inconvenient. Moreover, after the two leaves of the traditional hinge rotate, their rotation angle is not limited, so the opening and closing angle cannot be limited. When the door is opened at a too large angle, it will hit the wall. Summary of the invention
[0004] In order to solve the above problems, the utility model provides a special hinge for a tile and stone invisible door which can be first translated outwards and then rotated to open the door.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a special hinge for tile and stone invisible doors, including a support rod 1, an upper hinge assembly 2 and a lower hinge assembly 3 including a hinge main arm 4, a hinge arm 5 and a base 6 which are arranged in mirror symmetry, and a rotating pull rod 12 which is only arranged on the upper hinge assembly 2 or the lower hinge assembly 3, wherein the support rod 1 is a square tube structure, the upper part of which fixes the upper hinge assembly 2, and the lower part of which fixes the lower hinge assembly 3; the base 6 is a rectangular flat plate, and a plurality of screw holes are opened on the base 6, which are respectively fixed to the upper and lower beams of the door opening by bolts, and a distance is left for the movable frame 13 to be embedded in the door opening, and a pressure bearing 8 is arranged at the right position in the middle of the base 6.
[0006] The hinge main arm 4 and the hinge small arm 5 are rotatably connected through the same hinge pin 9. A vertical shaft sleeve 10 parallel to the hinge pin 9 is fixedly provided on the side of the end of the hinge main arm 4 away from the hinge pin 9. The shaft sleeve 10 is an internal thread structure, and an adjusting screw 11 matching it is installed on the internal thread of the shaft sleeve 10. The hinge main arm 4 is provided with threaded holes arranged up and down to be fixed to the support rod 1, and the hinge small arm 5 is provided with threaded holes arranged left and right to be fixed to the movable frame 13.
[0007] One end of the rotating pull rod 12 is rotatably arranged between the midpoint of the lower end of the hinge arm 5 and the hinge pin 9, and the other end is provided with a through hole, and the through hole is sleeved on the pull rod pin 14 of the base 6 away from the outside of the pressure bearing 8, forming a quadrilateral structure that can rotate and open and close around the fixed-point pressure bearing 8 and the pin 14.
[0008] Preferably, a main arm stop pin 7 is provided on the base 6 at a side away from the pin 14 to limit the rotation angle of the hinge main arm 4 .
[0009] Preferably, the hinge arm 5 of the lower hinge assembly 3 is L-shaped, with its vertical end surface fixed to the movable frame 13 , and the lower horizontal surface is used to lift the lower part of the movable frame 13 .
[0010] The movable frame 13 is provided with a decorative layer as a door panel on the outside, and the decorative layer is a tile. A suction cup is set on the surface of the tile at the opening of the movable frame 13 to facilitate the opening and closing of the door opening. After use, the suction cup can be removed to achieve a perfect invisible effect, and a magnet is set on the door opening at a corresponding position of the movable frame 13.
[0011] Beneficial effects: ① The door leaf of the utility model is made of the same material as the decorative wall panel, and the finishing is integrated, so the overall effect is better. The door leaf and the door frame are magnetically attracted and will not be easily opened without external force.
[0012] ② The utility model adopts a rotating pull rod 12, a hinge main arm 4, a hinge small arm 5, and a pressure bearing 8 to form corresponding geometric angles, so that when the door body is pulled, it first moves outward to a safe distance and then rotates to open. The translation and rotation are completed in one go without causing damage to the wall 15. The door body can be opened at an angle of 130 degrees for easy maintenance.
[0013] ③ The adjusting screw 11 of the utility model passes through the shaft sleeve 10 on the hinge arm 5 and then enters the pressure bearing 8 on the base 6. When there is a gap between the decorative wall panel on the movable frame 13 and the door opening, it is only necessary to rotate the longitudinal position of the adjusting screw 11 and the base 6. The adjustment is very convenient, and it effectively solves the problems of door body sinking and tilting caused by metal fatigue, and ensures the long-term, reliable, safe and stable use of the door body.
