[0004] The existing damping hinge is usually divided into two parts before safety, one part is fixedly connected with the door and window, and the other part is connected with the frame of the door and window, and then the two parts of the damping hinge are connected by bolts. Opening or closing, in the process of opening and closing, it is easy to cause the two parts of the damping hinge to vibrate relative to each other, causing the bolts used for connection to loosen, resulting in loosening of the connection between the two parts of the damping hinge, and dislocation of the door, window and door and window frame , affect the normal opening and closing of the doors and windows, when the doors and windows are closed, the doors and windows are very likely to collide with the door and window frames and make a lot of noise, and it is easy to cause damage to the doors and windows

Embodiment 1
[0046] see figure 1 , figure 2 , image 3 , Figure 8 and Figure 9 , a door and window hinge, including a main hinge 1 and an auxiliary hinge 2, and the main hinge 1 and the auxiliary hinge 2 are matched with each other, the main hinge 1 is sleeved on the auxiliary hinge 2, and the end of the main hinge 1 away from the auxiliary hinge 2 The main bolt groove 3 and the auxiliary bolt groove 4 are excavated. The main bolt groove 3 and the auxiliary bolt groove 4 are used to place the main bolt 5 and the auxiliary bolt 6 respectively. The main bolt 5 is placed in the main bolt groove 3, and the auxiliary bolt groove 4 is placed. There is an auxiliary bolt 6, and the main bolt groove 3 and the end of the auxiliary bolt 6 close to the main hinge 1 both penetrate the outer wall of the main hinge 1 and extend into the main hinge 1 and are fixedly connected with the auxiliary hinge 2. Both the main bolt 5 and the auxiliary bolt 6 are used For connecting the main hinge 1 and the a...

The invention discloses a door and window hinge, which belongs to the field of hinges. During the normal use process of the door and window, the door and window are often opened and closed. The main hinge and the auxiliary hinge cause a certain vibration, which makes the main bolt connecting the main hinge and the auxiliary hinge loose. By setting a protective cover at the bolt connecting the two parts of the damping hinge, when the relative displacement of the two parts of the damping hinge occurs, the damping The two parts of the hinge have a large vibration, and it is not easy to cause the bolts used for connection to loosen, and it is not easy to loosen the connection between the two parts of the damping hinge, so that the damping hinge is easy to maintain stable work for a long time, so that the doors and windows can be maintained for a long time The matching relative position is not easy to generate loud noise due to the collision between the door and window and the door and window frame when the door and window are closed, and is not easy to cause damage to the door and window.
Description
technical field [0001] The invention relates to the field of hinges, in particular to a door and window hinge. Background technique [0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between the two. The hinge can be composed of movable components or foldable materials. The hinge is mainly installed on doors and windows. Hinges are more installed on cabinets. According to the material classification, they are mainly divided into stainless steel hinges and iron hinges. In order to let people enjoy better enjoyment, hydraulic hinges (also known as damping hinges) have appeared. With the buffer function, the noise generated by the collision with the cabinet body when the cabinet door is closed is minimized. [0003] With the improvement of people's material living standards, the original single hinge has gradually disappeared from our home improvement vision, replaced by damping hinges. Compared with tradition...
