[0032] As shown in one embodiment, an adjustable anti-falling device includes: Figure 1 As shown in one embodiment, an adjustable anti-falling device includes:

[0033] The hanging portion 120;

[0034] The stop lever portion 130;

[0035] The connecting portion 110 is connected to the stop lever portion 130 and the hanging portion 120, and the stop lever portion 130 and the hanging portion 120 are located on the same side of the connecting portion 110, forming a hanging port 140 with an opening on one side.

[0036] The mounting base has two opposite side ends with adjustable length of the protruding rods, the end of the two rods is used to abut against the two side walls of the wall space, and the connecting part 110 is rotatably installed at the other side end of the mounting base;

[0037] In the first state, when the activity point 30 of the hanging part abuts against the bottom surface of the hanging part 120 and the hanging part 120 is rotated to the side without the hanging interface 140, until the activity point 30 is separated from the hanging part 120, at this time, the hanging part 120 returns to the original position, and the activity point 30 is located in the hanging interface 140; when the activity point 30 of the hanging part abuts against the bottom surface of the stop rod part 130 and the stop rod part 130 is rotated to the side without the hanging interface 140, until the activity point 30 is separated from the stop rod part 130, at this time, the stop rod part 130 returns to the original position, and the activity point 30 is located above the stop rod part 130;

[0038] In the second state, the activity point 30 of the hanging part abuts against the top surface of the stop rod part 130 and the stop rod part 130 is rotated to the side with the hanging interface 140, until the activity point 30 of the hanging part is separated from the stop rod part 130, at this time, the stop rod part 130 returns to the original position, and the activity point 30 of the hanging part is located below the hanging part 120.

[0039] The adjustable anti-falling device first abuts the end of the two rods of the mounting base against the wall surface at a suitable height to fix the mounting base; second, the connecting part 110 is rotatably installed at the side end of the mounting base, at this time, the structure composed of the connecting part 110, the hanging part 120 and the stop rod part 130 has the gravity center located in the lower half, and the hanging interface 140 opens to one side. When the lifting device rises, the activity point 30 of the hanging part extending therefrom rises together until it is engaged in the hanging interface 140, at this time, the height position of the lifting device is in the locked state; continuing to rise the height of the lifting device, the activity point 30 of the hanging part rises above the stop rod part 130, at this time, the height position of the lifting device is in the unlocked state, and the lifting device can be moved in the up-down direction. The hanging of the lifting device is stable and convenient, which reduces the workload of the workers and improves the safety factor of the construction site.

[0040] In the embodiment, the force balance point of the contact surface between the bottom end of the hanging part 120 and the activity point 30 is located on the side away from the opening of the hanging interface 140. Specifically, when the activity point 30 abuts against the bottom end of the hanging interface 140, the horizontal resultant force of the hanging part 120 is directed to the opposite direction of the opening of the hanging interface 140, the hanging part 120 is rotated away from the hanging interface 140, so that the activity point 30 enters the hanging interface 140, and the lifting device enters the locked state.

[0041] As Figure 3 , Figure 4In the embodiment, the bottom surface of the hanging portion 120 is an arc surface or a plane, and in the moving direction of the movable point 30, the side of the arc surface or the plane close to the opening of the hanging interface 140 is higher than the side far from the opening of the hanging interface 140. Specifically, because the length of the hanging part extended by the lifting device is fixed, the moving direction of the movable point 30 is fixed as a vertical straight line, and the side of the bottom surface of the hanging portion 120 close to the opening of the hanging interface 140 is higher than the other side relative to the straight line, so that the hanging portion 120 is forced to rotate away from the opening of the hanging interface 140 during the upward movement of the movable point 30.

[0042] In the embodiment, the bottom surface of the hanging portion 120 is an arc surface or a plane, and in the moving direction of the movable point 30, the side of the arc surface or the plane close to the opening of the hanging interface 140 is higher than the side far from the opening of the hanging interface 140. Specifically, because the length of the hanging part extended by the lifting device is fixed, the moving direction of the movable point 30 is fixed as a vertical straight line, and the side of the bottom surface of the hanging portion 120 close to the opening of the hanging interface 140 is higher than the other side relative to the straight line, so that the hanging portion 120 is forced to rotate away from the opening of the hanging interface 140 during the upward movement of the movable point 30.

[0043] In the embodiment, the bottom surface of the hanging portion 120 is an arc surface or a plane, and in the moving direction of the movable point 30, the side of the arc surface or the plane close to the opening of the hanging interface 140 is higher than the side far from the opening of the hanging interface 140. Specifically, because the length of the hanging part extended by the lifting device is fixed, the moving direction of the movable point 30 is fixed as a vertical straight line, and the side of the bottom surface of the hanging portion 120 close to the opening of the hanging interface 140 is higher than the other side relative to the straight line, so that the hanging portion 120 is forced to rotate away from the opening of the hanging interface 140 during the upward movement of the movable point 30.

[0044] In the embodiment, the bottom surface of the hanging portion 120 is an arc surface or a plane, and in the moving direction of the movable point 30, the side of the arc surface or the plane close to the opening of the hanging interface 140 is higher than the side far from the opening of the hanging interface 140. Specifically, because the length of the hanging part extended by the lifting device is fixed, the moving direction of the movable point 30 is fixed as a vertical straight line, and the side of the bottom surface of the hanging portion 120 close to the opening of the hanging interface 140 is higher than the other side relative to the straight line, so that the hanging portion 120 is forced to rotate away from the opening of the hanging interface 140 during the upward movement of the movable point 30.

[0045] In the embodiment, the bottom surface of the hanging portion 120 is an arc surface or a plane, and in the moving direction of the movable point 30, the side of the arc surface or the plane close to the opening of the hanging interface 140 is higher than the side far from the opening of the hanging interface 140. Specifically, because the length of the hanging part extended by the lifting device is fixed, the moving direction of the movable point 30 is fixed as a vertical straight line, and the side of the bottom surface of the hanging portion 120 close to the opening of the hanging interface 140 is higher than the other side relative to the straight line, so that the hanging portion 120 is forced to rotate away from the opening of the hanging interface 140 during the upward movement of the movable point 30.

[0046] In this embodiment, the bottom surface of the mounting interface 140 is lower than the opening of the mounting interface 140 in the direction of movement of the movable point 30. Specifically, the movable point 30 is engaged inside the mounting interface 140 to prevent the movable point 30 from sliding out of the mounting interface 140.

[0047] In this embodiment, the distance from the end of the stop lever portion 130 away from the connecting portion 110 to the mounting point 20 of the connecting portion 110 is greater than the distance from the end of the hook portion 120 away from the connecting portion 110 to the mounting point 20.

[0048] like Figure 2 As shown, in this embodiment, the mounting base further includes a mounting bracket 410, screws 430, and a threaded sleeve 440. The mounting bracket 410 has a mounting cavity 420. The two screws 430 have coincident axes and pass through opposite ends of the mounting bracket 410. The threaded sleeve 440 has opposite internal threads at both ends and is screwed onto opposite ends of the two screws 430. When the two screws 430 abut against the side walls of the wall space, the threaded sleeve 440 is screwed onto the two screws 430, making the installation of the screws 430 more stable.

[0049] Specifically, the mounting base is preferably provided with multiple longitudinal recesses on both sides of the wall space on which it is installed, for the ends of the two screws 430 to extend into and fix it.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
