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 of 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] like Figure 1-Figure 3 As shown, a construction safety ladder provided in an embodiment of the present application includes a first step 100, a second step 200 and a load-bearing plate 400, wherein the first step 100 and the second step 200 are straight ladder structures hinged to each other, and the first step 100 and the second step 200 can be adjusted according to actual needs to form a straight ladder or a folding ladder for use.

[0024] The first ladder 100 includes two first vertical rods 110, and a plurality of first cross rods 120 are evenly distributed between the two first vertical rods 110 along the length direction thereof, and the two first vertical rods 110 and the plurality of first cross rods 120 form the first ladder 100. Similarly, the second ladder 200 includes two second vertical rods 210, and a plurality of second cross rods 220 are evenly distributed between the two second vertical rods 210 along the length direction thereof, and the two second vertical rods 210 and the plurality of second cross rods 220 form the second ladder 200.

[0025] In this embodiment, the first vertical rod 110 is hingedly connected to the second vertical rod 210, so that the second ladder 200 can be rotated relative to the first ladder 100 to switch between a straight ladder and a folding ladder. In addition, a fastening bolt 300 is also provided on the first vertical rod 110. When the first vertical rod 110 is parallel to the second vertical rod 210, the fastening bolt 300 can be used to fix the first vertical rod 110 and the second vertical rod 210 together. Specifically, the first vertical rod 110 and the second vertical rod 210 can be hingedly connected through an ear plate 500.

[0026] The load-bearing plate 400 is located between the two first vertical rods 110, and one end of the load-bearing plate 400 is hingedly connected to the two first vertical rods 110. That is, the hinge point 420 of the load-bearing plate 400 is located near the first end thereof. The second end of the load-bearing plate 400 may be provided with a wing plate 440, and the overall length of the wing plate 440 and the load-bearing plate 400 is greater than the distance between the second vertical rods 210. In this embodiment, the bottom surface of the load-bearing plate 400 is provided with a locking groove 410, and the locking groove 410 is adapted to the second crossbar 220. When the first step 100 and the second step 200 are parallel to each other, the load-bearing plate 400 can be rotated to a position parallel to the two, and the locking groove 410 of the load-bearing plate 400 is buckled on the second crossbar 220 of the second step 200, and then cooperates with the structure of the fastening bolt 300 so that the safety ladder can be maintained in a straight ladder state.

[0027] In addition, the inner side surface of the wing plate 440 of the bearing plate 400 is provided with a snap-in groove 430, which is matched with the outer diameter of the second vertical rod 210. When the safety ladder is in the folding ladder state, there is a certain angle between the first step 100 and the second step 200. At this time, the bearing plate 400 rotates to a horizontal plane, and the snap-in groove 430 of the bearing plate 400 is connected to the second vertical rod 210. In this way, it can be ensured that the bearing plate 400 can be fixed on the horizontal plane, so that the staff can step on the bearing plate 400 to work.

[0028] In some embodiments, in order to improve the structural stability of the safety ladder in the folded ladder state, a lever 700 may be further provided on the first crossbar 120. Figure 1-Figure 3 As shown, one end of the lever 700 is rotatably disposed on the first crossbar 120, and a connecting piece is disposed on the second end of the lever 700, through which the lever 700 can be overlapped on the second crossbar 220 of the second step 200. In some possible implementations, the top end of the first vertical bar 110 and the bottom end of the second vertical bar 210 are provided with through holes 600 used in conjunction with the fastening bolts 300.

[0029] In the construction safety ladder provided by the embodiment of the present application, when the first vertical rod 110 and the second vertical rod 210 are adjusted to be parallel to each other, the two are fixed by the fastening bolts 300, and then the locking groove 410 of the bearing plate 400 is buckled on the second crossbar 220, so that the safety ladder can be adjusted to a straight ladder. When the first vertical rod 110 and the second crossbar 220 are adjusted to form a certain angle with each other, the second vertical rod 210 is overlapped in the clamping groove 430 on the side of the bearing plate 400, so that the bearing plate 400 can be horizontally overlapped between the first step 100 and the second step 200. With the above structural design, the structural design of the safety ladder can be adjusted according to actual needs, so that it can switch back and forth between a straight ladder and a folding ladder, thereby meeting the needs of construction projects.
