[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] See also Figure 1-4The utility model provides an anti-collision device for a lifting bed board, comprising a main crossbeam 1, wherein the number of the main crossbeams 1 is two, and connecting beams 2 are arranged on both sides between the two main crossbeams 1, and anti-collision frames 3 are arranged at both ends of the outer sides of the two connecting beams 2, and an anti-collision shaft 4 is arranged between the anti-collision frame 3 and the connecting beam 2, and the anti-collision frame 3 is rotatably connected to the connecting beam 2 through the anti-collision shaft 4, and the outer end of the anti-collision frame 3 is rotatably connected to an anti-collision wheel 5 through a rotating shaft, and the lower end of the anti-collision wheel 5 extends below the anti-collision frame 3, and the outer upper end of the anti-collision frame 3 is connected to the lower end of the anti-collision wheel 5 through the rotating shaft. An adjusting bolt 6 is threadedly connected, and the lower end of the adjusting bolt 6 abuts against the upper surface of the connecting beam 2. A switch bracket 7 is provided on the inner lower side of the anti-collision frame 3, and a compression spring 8 is provided between the switch bracket 7 and the anti-collision frame 3. A micro switch 9 is provided on the inner side of the switch bracket 7, and the detection end of the micro switch 9 abuts against the inner lower surface of the anti-collision frame 3. A profile frame 10 is provided on the outer side of the two connecting beams 2, and the lower end of the anti-collision wheel 5 abuts against the inner lower end of the profile frame 10, and a bed board 11 is provided between the two profile frames 10.
[0014] When in use, the two main beams 1 are connected by the connecting beam 2, and the bed board 11 is set to the upper ends of the connecting beam 2 and the main beam 1 through the profile frame 10. By screwing the adjusting bolt 6, the anti-collision frame 3 is driven to rotate under the support of the anti-collision shaft 4. During the rotation, the elastic force of the compression spring 8 is overcome, so that the anti-collision frame 3 is kept away from the micro switch 9, and the side of the anti-collision frame 3 close to the switch bracket 7 is rotated downward, so that one side of the anti-collision frame 3 and the contact of the micro switch 9 are kept in a position just in contact and not triggered, and the anti-collision frame 3 is under the bed board 11. When encountering an "obstacle" during the descending process, the profile frame 10 fixed to the bed board 11 generates an upward reaction force, causing the profile frame 10 to be displaced relative to the connecting beam 2, thereby driving the anti-collision wheel 5 to move upward together, and exerting a lever effect through the "fulcrum" of the anti-collision shaft 4, so that the anti-collision frame 3 generates a downward force and displacement on the side close to the switch bracket 7, pressing the contacts of the microswitch 9, triggering the alarm system, and urgently cutting off the power to stop the descending action of the bed board 12 and the profile frame 11, thereby protecting the patient's personal safety.
[0015] The switch bracket 7 is fixedly connected to the connecting beam 2 by bolts. A groove 12 is provided on the upper surface of the switch bracket 7. The lower end of the compression spring 8 is snapped into the interior of the groove 12. By setting the groove 12 on the switch bracket 7, the compression spring 8 is snapped into the interior of the groove 12 to prevent the compression spring 8 from being separated from the switch bracket 7.
[0016] 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.
