Technical Field

[0001] This utility model belongs to the field of ladder hanging technology, and in particular relates to a ladder hanging fixing structure. Background Technology

[0002] In building construction or power maintenance, hanging ladders are commonly used climbing equipment. Unlike common ladders, hanging ladders are fixed at the top and are used to climb walls, light poles, etc. that lack natural support or attachment points.

[0003] There are still some problems with the current hanging ladders in actual use. First, the current hanging ladders are generally fixed structures. If working on the roof, the staff need to carry the hanging ladder up by elevator or walk up the stairs. The fixed structure of the hanging ladder is relatively long, so it is very inconvenient to carry. In addition, the fixed structure at the top of the hanging ladder is too simple, and it is easy to sway when it is hung on a narrow wall. Utility Model Content

Detailed Implementation

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a ladder fixing structure, such as Figure 1-7As shown, the ladder includes several sets of ladder plates 1, which are connected by hinge blocks 2. The hinge blocks 2 are staggered along the parallel line of the ladder plates 1. Each ladder plate 1 has a through groove from top to bottom, and a limit block 3 is slidably embedded in the through groove. The limit blocks 3 are connected by a pull rope 4. The top limit block 3 is connected to a pull ring 5 by the pull rope 4. The pull ring 5 is located on the top outer side of the ladder plate 1. Insert rods 6 are installed on both sides of the bottom of the pull ring 5. The top of the ladder plate 1 has a slot that matches the insert rod 6. A bracket 7 is installed on the side of the top ladder plate 1. A sleeve plate 8 is installed on the outside of the bracket 7. A pressure plate 9 is installed on the lower side of the sleeve plate 8. The ladder is made up of several ladder plates 1 hinged together. In use, the ladder can be laid flat, and then the pull ring 5 on the top of the ladder plate 1 is pulled to pull the pull rope 4. The pull rope 4 moves upward, and this operation can pull the limit blocks 3 to their respective positions. At the connection point of each ladder 1, each ladder 1 is limited by the limiting block 3 and cannot rotate, thus keeping the entire ladder in a straight line. The entire ladder is then placed on the top of the wall and hung using the bracket 7 and pressure plate 9. After use, the pull rope 4 can be released. At this time, the limiting block 3 returns to its respective ladder 1 under the action of gravity. Since there is no limiting block 3 and the pull rope 4 itself is flexible, the ladder 1 can be bent and folded in opposite directions. This device, by hinged between the ladder 1 and locking the ladder 1 with the pull rope 4 and the limiting block 3, ensures that the ladder remains in a straight line during use and does not bend, improving safety. When carried, it can be rotated and folded, making the ladder easy to carry in the corridor, thus improving the practicality of the ladder.

[0025] The bottom of the limiting block 3 is connected to a connecting rod 11. The bottom ladder plate 1 has a groove, and a pad 10 is slidably embedded in the groove. The bottom of the connecting rod 11 is connected to the pad 10. A return spring 12 is sleeved on the outside of the connecting rod 11. By setting the connecting rod 11 and the return spring 12, when the ladder is in use, the elastic force generated by the return spring 12 can keep the pull rope 4 in a taut state, thereby preventing the limiting block 3 from moving and causing the ladder plates 1 to unlock and bend.

[0026] The left and right outer walls of the bracket 7 are provided with sliding grooves, and the left and right inner walls of the sleeve plate 8 are provided with limiting plates 13. The sleeve plate 8 is slidably sleeved on the outside of the bracket 7 through the limiting plates 13. A connecting shaft 14 is installed at the center of the right end of the sleeve plate 8 through a bearing. The inner end surface of the connecting shaft 14 is provided with threads. The inside of the bracket 7 is provided with a threaded groove that matches the thread on the surface of the connecting shaft 14. The connecting shaft 14 is threadedly connected to the bracket 7. One end of the connecting shaft 14 extends to the outside of the sleeve plate 8 and is connected to a handle 15. By providing the sleeve plate 8, the sleeve plate 8 is slidably sleeved on the outside of the bracket 7 and positioned by the connecting shaft 14. The connecting shaft 14 can be rotated to make the sleeve plate 8 slide relative to the bracket 7. This setting can adjust the distance between the pressure plate 9 and the ladder plate 1, so that the hanging ladder can be stably fixed on the wall surface of different thicknesses.

[0027] The sleeve 8 is fitted onto the outside of the bracket 7. This arrangement prevents the sleeve 8 from rubbing against the wall surface when sliding.

[0028] A ratchet 16 is fixedly sleeved on the outer side wall of the connecting shaft 14. A fixing rod 17 is installed on the right side of the sleeve plate 8. A connecting sleeve 18 is rotatably sleeved on the outside of the fixing rod 17. A spring 20 is installed on the outside of the fixing rod 17. The other end of the spring 20 is fixed to the side wall of the connecting sleeve 18. A pawl 19 is installed on the lower side of the connecting sleeve 18. The pawl 19 is engaged in the tooth gap of the ratchet 16. By setting the ratchet 16 and the pawl 19, when the connecting shaft 14 rotates to adjust the position of the pressure plate 9, the pawl 19 is locked by the spring force of the spring 20. This setting can limit the rotation of the connecting shaft 14 to prevent the pressure plate 9 from loosening and shaking when the ladder is in use, thereby further improving the safety of the ladder.

[0029] The top of the ladder plate 1 has two sets of slots that are compatible with the insertion rod 6. The two sets of slots are symmetrically distributed with two deep and two shallow slots. This setting can limit the pull ring 5 when it is pulled out and when it is retracted.
