DETAILED DESCRIPTION

[0022] 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.

[0023] Example: Reference Figure 1-5 A ceiling-mounted fall detector device is shown, comprising a mounting block 1 and a fall detector 3, a movable block 2 is arranged below the mounting block 1, the fall detector 3 is mounted on the bottom of the movable block 2, a plurality of fixed blocks 4 are mounted on the bottom of the mounting block 1, movable cavities are opened on the plurality of fixed blocks 4, two slide bars 7 are installed on the relative inner walls of the plurality of movable cavities, a slider 5 is commonly sleeved on every two matching slide bars 7, elastic mechanisms are arranged on the sides of the plurality of sliders 5, trapezoidal blocks 6 are installed on the other sides of the plurality of sliders 5, avoidance holes matched with the trapezoidal blocks 6 are opened on the sides of the plurality of fixed blocks 4, fixing grooves matched with the trapezoidal blocks 6 are opened on the four outer walls of the movable block 2, and a driving mechanism for simultaneously moving the plurality of sliders 5 is arranged on the mounting block 1.

[0024] With the above structure, when in use, first install the installation block 1 at the specified position. When the installation is completed, lift the movable block 2 so that its top contacts the trapezoidal block 6, and then press the movable block 2 upward. The force on the movable block 2 will squeeze the trapezoidal block 6, and the trapezoidal block 6 will move under the force, thereby causing the trapezoidal block 6 to shrink. Then continue to push the movable block 2. When the trapezoidal block 6 is aligned with the fixed groove, the trapezoidal block 6 is not subject to force at this time. The trapezoidal block 6 is not subject to force and will be reset under the action of the elastic mechanism and the slider 5. The reset of the trapezoidal block 6 will contact the inner wall of the fixed groove, making it impossible for the movable block 2 to move down, thereby quickly installing the fall detector 3. When maintenance is required, first move the slider 5 through the driving mechanism. The movement of the slider 5 will cause the trapezoidal block 6 to shrink, thereby releasing the fixation of the fall detector 3, thereby facilitating the disassembly and installation of the fall detector 3 and facilitating later maintenance and replacement.

[0025] As shown in the figure, the driving mechanism includes a movable groove opened at the bottom of the mounting block 1, and a rotating rod 10 is rotatably installed on the relative inner wall of the movable groove. One end of the rotating rod 10 extends to the outside of the mounting block 1 and is installed with a knob 11. A winding roller 12 is sleeved on the rotating rod 10, and the sides of multiple sliders 5 are installed with pull ropes 9. The tops of multiple fixed blocks 4 are opened with rope holes, and multiple pull ropes 9 respectively pass through the multiple rope holes. The bottom of the mounting block 1 is opened with multiple rope grooves compatible with the pull ropes 9, and the other ends of the multiple pull ropes 9 are respectively installed on the winding roller 12. The advantage of this arrangement is that through the arrangement of the rotating rod 10, the knob 11, the winding roller 12, the rope holes and the rope grooves, it is convenient to make multiple trapezoidal blocks 6 shrink at the same time.

[0026] Specifically, turning the knob 11 will cause the rotating rod 10 to rotate, and the rotation of the rotating rod 10 will reel in the pull rope 9 through the reel-up roller 12. At this time, the pull rope 9 is limited by the rope hole and the rope groove, thereby causing the slider 5 to move. The movement of the slider 5 will cause the trapezoidal block 6 to move, thereby releasing the fixation of the fall detector 3 for easy use.

[0027] like Figure 5 As shown, two partitions 13 are fixedly sleeved on the winding roller 12. The advantage of such an arrangement is that the winding roller 12 can be easily divided into several parts through the arrangement of the partitions 13, thereby preventing multiple pull ropes 9 from being wound together and tangled to affect their resetting.

[0028] like Figure 3As shown, a through cavity is provided on the mounting block 1, a ratchet 15 is sleeved on the rotating rod 10, a pawl 16 is rotatably installed on the relative inner wall of the through cavity, an elastic sheet 17 is installed on the side inner wall of the through cavity, the other end of the elastic sheet 17 is installed on the side of the pawl 16, a moving rod 18 is installed on the side of the pawl 16, a moving hole is provided on the side of the mounting block 1, and one end of the moving rod 18 passes through the moving hole. The advantage of such an arrangement is that, through the arrangement of the ratchet 15, the pawl 16, the elastic sheet 17 and the moving rod 18, it is convenient to limit the rotating rod 10, so as to avoid the rotating rod 10 from resetting and rotating under the action of the elastic mechanism and the pull rope 9 after the knob 11 is turned.

[0029] Specifically, when the rotating rod 10 rotates counterclockwise, the ratchet 15 will rotate counterclockwise, and the pawl 16 will avoid. When the rotating rod 10 is not subjected to force, the elastic extrusion and the pull rope 9 will give the rotating rod 10 a force to rotate in the opposite direction. At this time, the pawl 16 will no longer avoid, and the rotating rod 10 cannot be reversed and reset. When the disassembly is completed, the pawl 16 is avoided by moving the rod 18. At this time, the rotating rod 10 is reset and rotated under the action of the elastic mechanism and the pull rope 9, so that the trapezoidal block 6 is reset, which is convenient for the next use.

[0030] like Figure 4 As shown, the elastic mechanism includes a spring 8 installed on the side of the slider 5, and the other end of the spring 8 is installed on the inner wall of the side of the active cavity. The advantage of this arrangement is that, through the arrangement of the spring 8, when the slider 5 is not subjected to force, the slider 5 is reset under the elastic action of the spring 8, thereby resetting the trapezoidal block 6.

[0031] like Figure 1 As shown, two mounting plates 14 are installed on the sides of the mounting block 1 that are away from each other, and mounting holes are opened on the tops of the four mounting plates 14. Fixing bolts 19 are movably installed in the four mounting holes. The advantage of this arrangement is that the mounting block 1 is easy to install through the arrangement of the mounting plates 14 and the fixing bolts 19.

[0032] like Figure 4 As shown, buffer pads are installed on the sides of the plurality of sliders 5. The advantage of such an arrangement is that the buffer pads can play a certain buffering role and reduce the vibration generated when the sliders 5 are reset.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
