Description

A fixable door hinge

Technical field

The present invention relates to the technical field of loose-leaf hinges, and in particular to a fixable door hinge.

Background technique

A hinge, also known as a hinge, is a mechanical device used to connect two solid bodies and allow rotation between them. Hinges are made of components that can be moved or made of foldable materials. Hinges are widely used in daily life, such as doors, windows, various furniture, etc., and are also used in various mechanical devices. The material is mainly metal, which can be divided into stainless steel hinges and iron hinges. These hinges have a characteristic that they cannot fixedly connect two objects through the structure of the hinge itself. That is to say, the two objects connected by the hinge can always rotate with each other, but cannot remain relatively stationary against external forces.

The beneficial effects brought by the technical solutions provided by the embodiments of the present invention are: a fixable door hinge of the present invention, through the cooperation of the rotating shaft and the chute, when the rotating shaft slides to both ends of the chute, the hinge is in a rotatable or fixed state. There are two working states. When the hinge is in a rotatable state, the limit block and the limit groove are separated. The rotating block can rotate around the rotating shaft. After rotating to the appropriate position, the rotating block is pushed to make the rotating shaft slide along the chute. The limiting block is contained in The limit slot is stuck and fixed, the hinge is converted into a fixed state, and the rotating block cannot rotate. When the hinge of the present invention is used to connect the door frame and the door, the door can rotate at any angle and remain relatively stationary while resisting external force.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

Please refer to FIGS. 1 and 4 , an embodiment of the present invention provides a fixable door hinge, which includes a hinge base 1 and a hinge part 2 .

Please refer to Figure 1, Figure 2 and Figure 3. One side of the hinge base 1 is fixed on a fixed member. In this embodiment, the hinge is used to connect the door frame and the door. The hinge base 1 is provided with two fixed parts. Hole 6, the hinge seat 1 is fixed on the door frame through fasteners and the fixing hole 6, so that the hinge seat 1 and the door frame are fixed together and kept vertically. The fasteners here can Select screws or bolts. The other opposite side of the hinge seat 1 is provided with a limiting groove 3 and a movable groove 4. The cross section of the limiting groove 3 is designed to be polygonal. In this embodiment, the limiting groove 3 is shaped like a rectangular column. The height of the limiting groove 3 is equal to the height of the movable groove 4, and the upper and lower ends of the limiting groove 3 and the movable groove 4 are aligned, and the width of the movable groove 4 is greater than the width of the movable groove 4. The width of the limiting groove 3 is the width of the limiting groove 3. The limiting groove 3 is located inside the movable groove 4 and the two are integrated. The horizontal symmetry plane of the limiting groove 3 coincides with the horizontal symmetry plane of the movable groove 4. , The upper end surface and the lower end surface of the movable groove 4 are both provided with oval chute 5, and the two chute 5 are arranged opposite to each other up and down.

Please refer to Figures 4, 5 and 6. The hinge 2 includes a limiting block 7 and a rotating block 8. The limiting block 7 has the same shape as the limiting groove 3. The rotating block 8 has an upper and lower position. The surfaces are provided with rotating shafts 9. The axes of the two rotating shafts 9 coincide with each other, and the two rotating shafts 9 are respectively arranged on the upper and lower end surfaces of the rotating block 8 close to the limiting block 7. The diameter of the rotating shaft 9 is equal to The length of the short axis of the chute 5 is the same, and the length of the short axis of the chute 5 can also be set slightly larger than the diameter of the rotating shaft 9 . The limiting block 7 is received in the limiting groove 3. Since the limiting block 7 and the limiting groove 3 have the same shape, the limiting block 7 can enter the limiting groove 3 and enter the limiting groove 3. It cannot rotate after that, and the rotating block 8 is accommodated in the movable groove 4. The two rotating shafts 9 are respectively disposed in the two chute 5 and can slide synchronously.

One side of the rotating block 8 is connected to the limiting block 7, and the other side is provided with a connecting portion 10. The connecting portion 10 is a flat plate structure. The connecting portion 10 is used to cooperate with the door to push or pull the door. The door can allow the rotating block 8 to slide along the chute 5 relying on the rotating shaft 9. When the rotating shaft 9 slides to the end of the chute 5 close to the limiting groove 3, the limiting block 7 is completely closed. Entering the limit groove 3 and being stuck, the rotating block 8 cannot rotate and the hinge is in a fixed state; when the rotating shaft 9 slides to the end of the chute 5 away from the limit groove 3, the The limiting block 7 leaves the limiting groove 3, the limiting block 7 and the rotating block 8 are rotatable, and the hinge is in a rotatable state, that is, the door can rotate together with the rotating block 8. When the required angle is reached, by pushing the door to fix the hinge, the door can be kept relatively stationary against external force.
