DETAILED DESCRIPTION
[0020] 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. Example
[0021] See also Figure 1-4 The utility model provides the following technical solutions: a convenient safety escape ladder, including a storage box 1, a disengagement opening 19 is opened on one side of the bottom end of the inner wall of the storage box 1, support blocks 2 are welded at one corner of the top side of the storage box 1 and one corner of the bottom side of the storage box 1, and a protective door 3 is hingedly installed between the two support blocks 2 through a damping shaft, and installation holes 4 are opened at the four corners of one end of the storage box 1, and expansion bolts 5 are installed through the installation holes 4. Strengthening blocks 18 are symmetrically welded on both sides of the storage box 1, and support holes 6 are opened in the middle of both sides of the inner wall of the storage box 1. A support rod 7 is passed through the support hole 6, and the length of the support rod 7 is the same as that of the storage box 1. A limited circular plate 8 is welded to one end of the support rod 7, and a gear 9 is welded to the other end of the support rod 7. A rectangular slot is opened in the middle of one side of the gear 9, and a rocker 10 is arranged on the side of the gear 9. A rectangular plug is arranged in the middle of one side of the rocker 10, and the rectangular plug is adapted to the rectangular slot to facilitate the plug-in installation of the rocker 10. Two groups of fixing blocks 11 are arranged on the outer wall of the support rod 7, and the number of each group of fixing blocks 11 is two. A rope ladder 12 is installed on the outer wall of the support rod 7 near the two groups of fixing blocks 11;
[0022] A limit box 13 is welded on one side of the storage box 1 near the gear 9, and a guide slide hole 14 is opened in the middle of one side of the limit box 13. A limit spring 15 is installed at one end of the inner wall of the limit box 13, and one end of the limit spring 15 is connected to a guide slider 16. A convex tooth block 17 is provided at one end of the guide slider 16, and a push plate is provided on one side of the guide slider 16. The push plate passes through the guide slide hole 14, which can limit the movement of the guide slider 16 and facilitate the use of the guide slider 16. The convex tooth block 17 is adapted to the gear 9, and the gear 9 can be locked and limited.
[0023] The working principle and use process of the utility model are as follows: the user fixes the storage box 1 on the wall by installing the expansion bolts 5. When the rope ladder 12 is needed, the user turns to open the protective door 3, and then the user pulls the push plate of the guide slider 16 by hand to move, so that the convex tooth block 17 of the guide slider 16 is out of contact with the gear 9, and then a pulling rope ladder 12 is provided to move down. When the bottom of the rope ladder 12 moves to a suitable position, the user releases the guide slider 16, and the guide slider 16 is pushed to move under the action of the elastic potential energy of the limit spring 15, so that the convex tooth block 17 moves again to contact with the gear 9 to limit the gear 9. By limiting the gear 9, the rotation of the support rod 7 can be avoided, and then the user uses the rope ladder 12 for safe escape;
[0024] When the rope ladder 12 needs to be rolled up, the user takes out the rocker 10 from the storage box 1 and connects the rocker 10 to the gear 9. Then the user pulls the push plate of the guide slider 16 by hand to move the protruding tooth block 17 of the guide slider 16 out of contact with the gear 9 and shakes the rocker 10. The rotation of the rocker 10 drives the support rod 7 to rotate synchronously, thereby realizing the winding of the rope ladder 12, which is convenient for the subsequent use of the escape ladder.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
