[0020] The utility model is further described in detail below with reference to the accompanying drawings. A flip-up door hinge with a pause function, comprising a mounting seat 2 connected to the outer wall of a box body 1, a mounting cavity 21 being provided inside the mounting seat 2, a movable seat 3 being hingedly mounted at the end of the mounting cavity 21 and connected to the door body 11, characterized in that: an elastic device 5 is installed in the mounting cavity 21, the elastic device 5 and the movable seat 3 are linked by a connecting rod 4, one end of the connecting rod 4 is hinged to the inner end of the movable seat 3, and the other end thereof is extended to be connected to a movable rod 51 of the elastic device 5, the elastic device 5 generates a pulling force to pull the connecting rod 4 downward to swing, and the door body 11 is always pulled outward through the movable seat 3;
[0021] The elastic device 5 comprises a movable rod 51 and a fixed rod 52 respectively installed across the upper and lower ends of the installation cavity 21, and two ends of a plurality of springs 6 are respectively detachably hooked between the movable rod 51 and the fixed rod 52;
[0022] A guide rod 7 is inserted between the movable seat 3 and the mounting seat 2. Correspondingly, guide grooves 23 are formed on both side walls of the mounting seat 2. Both ends of the guide rod 7 are respectively inserted into the guide grooves 23, and the movable seat 3 can slide along the guide grooves 23. The guide grooves 23 are in an arc shape.
[0023] The movable seat 3 and the mounting seat 2 are hingedly connected through a hinge shaft 8. The elastic device 5 also includes a torsion spring 9 arranged on the outer cylindrical surface of the hinge shaft 8. One end of the torsion spring 9 is pressed against the outer wall of the movable seat 3, and the other end is pressed against the guide rod 7.
[0024] The two side walls of the mounting seat 2 are penetrated with movable grooves 22 , and both ends of the movable rod 51 are respectively inserted and extended out of the end surfaces of the movable grooves 22 , and the movable rod 51 can slide along the movable grooves 22 .
[0025] The connecting rod 4 is provided with a limiting groove 41 corresponding to the movable groove 22 , and the movable rod 51 passes through the limiting groove 41 in sequence and is connected to the movable groove 22 .
[0026] The movable groove 22 and the limiting groove 41 are both arranged in a long waist shape.
[0027] The two side walls of the mounting seat 2 are penetrated with fixing holes, and the two ends of the fixing rod 52 are respectively inserted into the fixing holes.
[0028] The spring 6 is configured as a tension spring, and at least one spring is configured.
[0029] The movable seat 3 and the mounting seat 2 are interlaced and hinged through a hinge shaft 8, and a torsion spring 9 is arranged on the outer cylindrical surface of the hinge shaft 8. One end of the torsion spring 9 presses against the outer wall of the movable seat 3, and the other end presses against the port of the mounting seat 2.
[0030] Working principle: In this case, it is fixedly connected to the outer wall of the box body through a mounting seat, and connected to the door body through a movable seat, and the mounting seat and the fixed seat are hingedly installed.
[0031] An elastic device is provided on the internal mounting cavity of the mounting seat, and the elastic device and the movable seat are linked to operate through a connecting rod. It should be noted that when the door body is opened, the movable seat is pressed down and swung along its hinge axis, synchronously driving the connecting rod to swing downward. Since the elastic device always provides a pulling force to the connecting rod, the pull rod is always in a downward swinging tendency state. When the movable seat synchronously drives the connecting rod to swing downward, the elastic device provides constant pulling force support to the door body, and the movable seat always pulls the door body to move outward, prompting the door body to open, and locks the open state of the door body, ensuring a smooth and continuous opening process of the door body. Similarly, when the door body is closed, the elastic device also provides a pulling force to slow down the closing of the door body, so that the door body is subjected to uniform force when opening or closing, thereby reducing the vibration and noise caused by the operation of the door body and improving the user's comfort.
[0032] It should be noted that the elastic device includes a movable rod and a fixed rod installed at the upper and lower ends of the mounting cavity, and the two ends of the movable rod are respectively inserted and clamped in the movable grooves provided on the two side walls of the mounting seat, so as to limit the movable rod to slide in the movable groove. The fixed rod is fixedly inserted and connected in the fixing holes provided on the two side walls of the mounting seat. Furthermore, a plurality of springs are detachably hooked between the movable rod and the fixed rod, and the springs provide pulling force to the elastic device. At the same time, at least one spring is provided, that is, the spring can also be provided as two or three. The user can choose the number of springs according to the weight of the door body or the use environment, so that the door hinge can adapt to door bodies of different sizes or weights, providing better versatility and flexibility, and adapting to a wider range of installation needs.
[0033] The spring can be set as a tension spring or as an elastic structure with the same function, and the connecting structure is a detachable hook design, which makes the installation and replacement of the spring more convenient without the need for professional tools or complicated operations, thereby lowering the installation threshold of the door hinge. Ordinary users can also adjust the elastic force of the door hinge.
[0034] Furthermore, in order to make the door body have the function of stopping with it, the movable seat 3 and the mounting seat 2 in this case are interlaced and hinged through the hinge shaft 8, and the elastic device 5 also includes a torsion spring 9 set on the outer cylindrical surface of the hinge shaft 8. One end of the torsion spring 9 is pressed against the outer wall of the movable seat 3, and the other end is pressed against the guide rod 7. In addition to providing the rebound opening force of the hinge, the torsion spring also generates a thrust to drive the guide rod 7 toward the side wall of the guide groove 23, so that the guide rod 7 generates a greater friction force with it when it moves in the guide groove, and the friction force is balanced with the weight of the tension spring and the door body, so that the door body can stop when it is opened to the range of 70-90 degrees, thereby meeting the user's door opening needs.
[0035] Furthermore: in order to ensure the accuracy of the door movement trajectory, a limit slot is set at the corresponding movable slot position of the connecting rod. The movable rod first passes through the limit slot to connect with the movable slot, which limits the opening angle and strength of the door. At the same time, a guide rod is set to connect the movable seat with the mounting seat, which limits the movable seat to slide only along the movement trajectory of the guide rod, that is, the guide slots on the two side walls of the mounting seat, ensuring that the movable seat slides along a specific trajectory, ensuring the correct opening and closing of the door, avoiding the deviation or dislocation of the door, and improving the safety and stability of the door.
[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
