Abstract
Description
Technical Field
[0001] The utility model belongs to the field of door and window hinges, in particular to a hinge which can adjust the gap between a fan body and a frame body by moving a fan body left and right in a closed state. Background Art
[0002] The existing door and window hinges support the sash body by propping up multiple connecting rods through the frame mounting plate. In the closed state, the gap between the sash body and the frame due to installation needs to be adjusted to ensure the airtightness between the door and window sash and the door and window frame. Most of the adjustment devices are to add a slide plate to the frame mounting plate, and then the slide plate supports multiple connecting rods and the sash mounting plate, and the eccentric nail on the slide plate drives the slide plate, multiple connecting rods and the door and window sash to slide together. At this time, the slide plate has a large load-bearing capacity. If the eccentric nail drives the slide plate, a larger torque needs to be added. Utility Model Content
[0003] The utility model aims to provide an adjustable safety hinge, which can adjust the installation gap between the fan body and the frame body more labor-savingly and maintain the sealing of doors and windows.
[0004] The adjustable safety hinge includes a frame fixing plate, a main support plate, a secondary support plate and a fan support plate. The frame fixing plate is rotatably connected to the fan support plate through the main support plate and the secondary support plate. A vertical vertical plate is provided at one end of the fan support plate. A sliding groove is provided from the vertical plate along the length direction of the fan support plate. An L-shaped plate is installed in the sliding groove. One branch of the L-shaped plate is slidably installed in the sliding groove. The other branch of the L-shaped plate is connected to the vertical plate through an adjusting screw.
[0005] An L-shaped support plate is provided at one end of the fan support plate, one branch of the L-shaped support plate is sleeved on the adjusting screw, the other branch of the L-shaped support plate is provided at the bottom of the fan support plate and is opposite to the position of the slide groove, and the two sides of the other branch of the L-shaped support plate correspond to the two sides of the fan support plate to form slide rail grooves.
[0006] The width of the other support plate of the L-shaped support plate is smaller than the width of the fan support plate.
[0007] One end of the main support plate is rotatably connected to the bottom of the slide groove, the other end of the main support plate is rotatably connected to the frame fixing plate, one end of the secondary support plate is rotatably connected to the middle part of the fan support plate, the other end of the secondary support plate is rotatably connected to the frame fixing plate through the first support plate, the middle part of the secondary support plate is rotatably connected to the frame fixing plate through the second support plate, the middle part of the second support plate is rotatably connected to the frame fixing plate through the third support plate, and the second and third support plates are arranged between the main support plate and the secondary support plate.
[0008] The frame fixing plate is provided with a first limit block for limiting the main support plate and the second support plate and a second limit block for limiting the third support plate. The first limit block is arranged between the main support plate and the second support plate, and the second limit block is arranged between the third support plate and the first support plate.
[0009] The adjustable safety hinge also includes a limit lock arranged on the frame fixing plate, and the limit lock is used for limiting the position of the hinge when it is extended to a certain angle.
[0010] The limit lock includes a lock box, which is provided with a waist-shaped hole along the length direction of the frame fixing plate, a lock platform for limiting the first support plate is provided at one end of the lock box, a limit column is provided on the outer side of the first support plate of the frame fixing plate, the waist-shaped hole is sleeved on the limit column, a limit plate is provided at the other end of the lock box, and the frame fixing plate is provided with a limit groove for limiting the limit plate.
[0011] The beneficial effects of the utility model are as follows: the L-shaped plate is slid in the slide groove by the spiral transmission of the adjusting screw, so that the L-shaped plate drives the door and window sash to move left and right, so as to achieve the purpose of adjusting the installation gap between the sash body and the frame body, thereby improving the sealing of the door and window and ensuring the left-right symmetry of the door and window. Since the bearing force of the sash body is concentrated on the sash support plate during adjustment, and the sash body slides along both sides, the adjustment resistance is reduced, making the adjustment more labor-saving. The lock tongue of the limit lock is turned to limit the rotation direction of the first support plate, so that each support plate is locked, so as to prevent children from accidentally operating the hinge to open and causing danger.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0016] like Figure 1 , 2As shown, the adjustable safety hinge includes a frame fixing plate 1, a main support plate 2, a secondary support plate 3, a first support plate 4, a second support plate 5, a third support plate 6, a fan support plate 7 and a limit lock 8. A vertical vertical plate 9 is provided at one end of the fan support plate 7, and a slide groove 10 is provided from the vertical plate 9 along the length direction of the fan support plate 7. One end of the main support plate 2 is rotatably connected to the bottom of the slide groove 10, the other end of the main support plate 2 is rotatably connected to the frame fixing plate 1, one end of the secondary support plate 3 is rotatably connected to the middle part of the fan support plate 7, the other end of the secondary support plate 3 is rotatably connected to the frame fixing plate 1 through the first support plate 4, the middle part of the secondary support plate 3 is rotatably connected to the frame fixing plate 1 through the second support plate 5, the middle part of the second support plate 5 is rotatably connected to the frame fixing plate 1 through the third support plate 6, and the second support plate 5 and the third support plate 6 are arranged between the main support plate 2 and the secondary support plate 3.
[0017] The frame fixing plate 1 is provided with a first limit block 11 and a second limit block 12, the first limit block 11 is provided between the main support plate 2 and the second support plate 3, and the second limit block 12 is provided between the third support plate 6 and the first support plate 4. The first limit block 11 limits the main support plate 2 and the second support plate 5 along the length direction of the frame fixing plate 1 during the rotation process, and the second limit block 12 limits the third support plate 6 along the length direction of the frame fixing plate 1 during the rotation process.
[0018] The slide groove 10 is installed with an L-shaped plate 13, one of which is slidably installed in the slide groove 10, and the other of which is connected to the vertical plate 9 through an adjusting screw 14. An L-shaped support plate 15 is provided at one end of the fan support plate 7, one of which is sleeved on the adjusting screw 14, and the other of which is arranged at the bottom of the fan support plate 7 and opposite to the slide groove 10. Since the width of the other of which is smaller than the width of the fan support plate 7, the two sides of the other of which form a slide rail groove 16 with the two sides of the fan support plate 7. The door and window sashes are supported on the fan support plate 7, and the two sides of the door and window sashes are slidably installed in the slide rail groove 16, and the ends of the door and window sashes are fixed by screws through the mounting holes 17 arranged on the other of which is the L-shaped plate 13.
