Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Please refer to fig. 2-6, the utility model provides a hidden hinge, including base 2, head rod 3, second connecting rod 4, third connecting rod 5 and trailing arm 6, the one end of head rod 3, second connecting rod 4 is rotated and is installed on base 2, the other end of head rod 3 is rotatable to be installed on trailing arm 6, the other end of second connecting rod 4 is rotatable to be installed in the one end of third connecting rod 5, the other end of third connecting rod 5 is rotatable to be installed on trailing arm 6, the one end of head rod 3 and the one end of second connecting rod 4 are equipped with first connecting tooth 31 and second connecting tooth 41 respectively, first connecting tooth 31 is connected with the meshing of second connecting tooth 41.
Specifically, one end of each of the first connecting rod 3 and the second connecting rod 4 is mounted in the middle of the base 2 through a rotating shaft 21, the other end of the first connecting rod 3 is rotatably mounted at one end of the support arm 6 through the rotating shaft 21, the other end of the second connecting rod 4 is rotatably mounted at one end of the third connecting rod 5 through the rotating shaft 21, and the other end of the third connecting rod 5 is rotatably mounted in the middle of the support arm 6 through the rotating shaft 21.
After the technical scheme is adopted, the hidden hinge realizes the opening and closing of the supporting arm through the moving system consisting of the base 2, the supporting arm 6, the first connecting rod 3, the second connecting rod 4 and the third connecting rod 5, and because the parts are connected with each other through the rotating shaft 21, the first connecting teeth 31 and the second connecting teeth 41, the connecting rod and the base sliding groove device in the prior art are not arranged, the problems of jamming and abrasion in the prior art are effectively solved, and the use is more smooth.
In this embodiment, the rotating shaft 21 is made of a pin, and when the bracket arm 6 is pushed to move, the first connecting tooth 31 and the second connecting tooth 41 rotate around the rotating shaft 21, respectively. After adopting above technical scheme, first connection tooth 31 and second connection tooth 41 use axis of rotation 21 respectively as the center rotation and intermeshing, rotate and can not produce the noise, and the operation is also more accurate, high-efficient, smooth and easy.
In the present embodiment, the first connecting tooth 31 and the second connecting tooth 41 are respectively opened at the ends of the first connecting rod 3 and the second connecting rod 4, and the first connecting tooth 31 and the second connecting tooth 41 respectively include a plurality of teeth. The number of teeth is determined by the rotational stroke of the first coupling teeth 31 and the second coupling teeth 41.
Referring to fig. 5, referring to other views, in the present embodiment, a base mounting portion 22 is disposed on the base 2, the base mounting portion 22 and the base 2 form a mounting space (not shown), one end of the first connecting rod 3 and one end of the second connecting rod 4 are rotatably mounted in the mounting space through two mounting shafts 21, and the two mounting shafts 21 respectively pass through the base mounting portion 22, the first connecting rod 3/the second connecting rod 4, and the base 2 to mount the first connecting rod 3 and the second connecting rod 4 on the base 2. The first coupling teeth 31 and the second coupling teeth 41 are installed in the installation space and rotate around the installation shaft 21, respectively.
Because the first connecting rod 3 and the second connecting rod 4 mainly bear the weight of the door and window sash in the using process of the hidden hinge, the joints of the first connecting rod 3 and the second connecting rod 4 and the base 2 are easy to damage after long-term pressure bearing. After the technical scheme is adopted, because the base installation part 22 is arranged, one ends of the first connecting rod 3 and the second connecting rod 4 are installed between the base installation part 22 and the base 2 and are fixed by the connecting shaft 21, the connection strength of the first connecting rod 3, the second connecting rod 4 and the base 2 can be greatly improved, and the service life is prolonged.
Referring to fig. 5, the base mounting portion 22 and the base 2 are integrated, and the base mounting portion 22 is manufactured by a bending process. By adopting the structure and the manufacturing process, the technical effects of simple manufacturing process and high strength are achieved.
Referring to fig. 5, referring to other views, a base mounting hole 23 is formed between the base mounting portion 22 and the base 2, and the outermost ends of the first connecting tooth 31 and the second connecting tooth 41 are located outside the base mounting hole 23, so that the first connecting tooth 31 and the second connecting tooth 41 can be conveniently mounted and moved.
Referring to fig. 5 and 6, a bending portion 31 is disposed in the middle of the first connecting rod 3, the bending portion 31 reserves a space for the movement of the third connecting rod 3, and the movement of the third connecting rod 3 is not blocked in the opening and closing process of the door and window.
Referring to fig. 5, the base 2 is provided with a base hole 24 for mounting the base 2 on the door window frame 7. In use, the base 2 is mounted to the door or window frame 7 by screws through the base apertures 24 and the door or window sash 8 is mounted to the bracket arms 6 by screws. Referring to fig. 5, when the door sash 8 is closed, the bracket arm 6 rotates clockwise, the first connecting rod 3 and the second connecting rod 4 rotate counterclockwise and clockwise, respectively, the third connecting rod 5 rotates counterclockwise, and when the bracket arm 6 rotates to be parallel to the base 2, the first connecting rod 3, the second connecting rod 4 and the third connecting rod 5 all rotate to be parallel to the base 2, referring to fig. 4, at this time, the door and window is in a closed state. In the same way, when the door and window is opened, the door and window moves in the opposite direction of closing the door and window, and when the door and window sash 8 is completely opened, the bracket arm 6 is basically in the position vertical to the base 2, and the door and window is in the opening state.
