[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-3The present invention provides a technical solution: a speed-limited automatic opening and closing door structure, comprising a door frame 1 and a door 3, wherein the door frame 1 comprises two vertical sections and one horizontal section, and the vertical section of the door frame 1 is rotatably connected to one end of the door 3; Figure 3 As shown, a driving member is provided on one side of the lower part of the vertical section located in the room, the output shaft of the driving member is fixedly connected to one end of the horizontal rod, the horizontal rod rotates in the horizontal plane, a buckle 4 is installed at the bottom end of the door frame 1, the other end of the horizontal rod is rotatably connected to one end of the pull rod 10, the other end of the pull rod 10 is rotatably connected to the middle part of the connecting rod 5, one end of the connecting rod 5 is rotatably connected to the door frame 1, and the other end of the connecting rod 5 is detachably connected to the bottom end of the door 3 through the buckle 4. When the connecting rod 5 is subjected to excessive force, the buckle 4 and the connecting rod 5 are separated, and the driving member drives the horizontal rod to rotate horizontally, and the horizontal rod drives the door 3 to open and close through the pull rod 10, the connecting rod 5 and the buckle 4.
[0019] Specifically, Figure 2 As shown, the fastener 4 includes an adjusting nut 7, a compression spring 8 and a lever 9. A circular groove opening upward is provided at the bottom end of the door 3. A thread is provided on the upper part of the inner wall of the circular groove. The thread on the inner wall of the circular groove is threadedly connected to the lower end of the adjusting nut 7. The top of the lever 9 is fixedly connected to the adjusting nut 7. The bottom end of the lever 9 passes through and extends to the bottom of the circular groove. A compression spring 8 is sleeved on the lever 9 between the bottom end of the adjusting nut 7 and the bottom side of the circular groove. A clamping groove is provided on the end of the connecting rod 5 away from the lever 9, and the bottom end of the lever 9 is inserted into the clamping groove.
[0020] Furthermore, an arc section is provided at the bottom end of the shifting rod 9 , and the arc section is not completely inserted into the engaging groove of the connecting rod 5 .
[0021] Furthermore, the inner diameter of the clamping groove gradually decreases from top to bottom.
[0022] When the speed reducer rotates too fast or the door is stuck during door opening and closing, the connecting rod 5 is subjected to excessive force, the lever 9 is disengaged from the connecting rod 5, and the door 3 stops rotating due to loss of external force, thus ensuring the safety of the speed-limited automatic opening and closing door structure.
[0023] There is an inclined surface between the lever 9 and the connecting rod 5. The inclined surface has a component force that causes the lever 9 to disengage from the matching inclined surface upward. The deformation length of the compression spring 8 is adjusted by adjusting the overlapping length of the adjusting nut 7 and the circular groove at the bottom end of the door 3, thereby adjusting the size of the inclined surface component force required for the lever 9 to disengage from the connecting rod 5, thereby improving the applicability of the speed-limited automatic opening and closing door structure.
[0024] In this embodiment, the vertical section of the door frame 1 and one end of the door 3 are connected by a hinge 2.
[0025] The driving component of this embodiment includes a reducer and a driving motor 6. The input shaft of the reducer and the output shaft of the driving motor 6 are connected by a coupling. The output shaft of the reducer is fixedly connected to an end of the horizontal rod away from the connecting rod 5. The input end of the driving motor 6 is electrically connected to the output end of the external power supply. The driving motor 6 drives the horizontal rod to rotate horizontally through the reducer, and the horizontal rod drives the door 3 to open and close through the pulling rod 10, the connecting rod 5 and the buckle 4.
[0026] When using:
[0027] The door frame 1 is fixed to the ground or the wall, the door 3 rotates freely around the hinged leaf 2, the door 3 is connected to the connecting rod 5 by a buckle 4, the driving motor 6 works, the driving motor 6 drives the horizontal rod to rotate in the horizontal plane through the reducer, and the horizontal rod drives the door 3 to open and close through the pulling rod 10, the connecting rod 5 and the buckle 4; the moving connecting rod 5 drives the door 3 to open and close through the clamping groove on the connecting rod 5 and the arc segment of the lever 9, and the door 3 rotates around the hinged leaf 2;
[0028] Since the door has inertia when it rotates from a stationary state, the faster the door rotates, the greater the inertia. The lever 9 needs to exert a greater force on the door 3 to make the door 3 rotate around the hinge 2. Since the lever 9 and the connecting rod 5 are matched with an inclined surface, the inclined surface has a component force F that causes the lever 9 to disengage from the matching inclined surface upward. This component force F is balanced by the elastic force of the compression spring 8. When the inertia force of the door 3 gradually increases, the component force F also increases. When the component force F is greater than the elastic force of the compression spring 8, the lever 9 will move upward, the lever 9 will disengage from the connecting rod 5, and the door will stop rotating without the external force.
[0029] In the present invention, when the speed reducer rotates too fast or the door is stuck during door opening and closing, the connecting rod 5 is subjected to excessive force, the lever 9 is separated from the connecting rod 5, and the door 3 stops rotating without external force, thereby ensuring the safety of the speed-limited automatic door opening and closing structure.
[0030] There is an inclined surface between the lever 9 and the connecting rod 5. The inclined surface has a component force that causes the lever 9 to disengage from the matching inclined surface upward. The deformation length of the compression spring 8 is adjusted by adjusting the overlapping length of the adjusting nut 7 and the circular groove at the bottom end of the door 3, thereby adjusting the size of the inclined surface component force required for the lever 9 to disengage from the connecting rod 5, thereby improving the applicability of the speed-limited automatic opening and closing door structure.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
