[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 3 This utility model discloses a quick-assembly and disassembly carbon fiber climbing ladder, comprising: multiple carbon fiber connecting rods 2, the ends of two adjacent carbon fiber connecting rods 2 being detachably connected by quick-release pins, a hook 1 fixedly connected to one end of the carbon fiber connecting rod 2, the hook 1 being used to hang the climbing ladder on a wall, multiple foot pedals 3 fixedly connected to the carbon fiber connecting rod 2, the multiple foot pedals 3 being located on opposite sides of the carbon fiber connecting rod 2, the multiple foot pedals 3 on the same side being equally spaced along the length direction of the carbon fiber connecting rod 2, the multiple foot pedals 3 on both sides being staggered, a support base 4 fixedly connected to the carbon fiber connecting rod 2, the support base 4 abutting against the wall, so that there is a distance between the carbon fiber connecting rod 2 and the wall.

[0023] In this invention, the climbing ladder is composed of multiple carbon fiber connecting rods 2, and adjacent carbon fiber connecting rods 2 are detachably connected by quick-release pins. When not in use, the climbing ladder can be disassembled into multiple carbon fiber connecting rods 2. Since the carbon fiber connecting rods 2 are lightweight, they are easy to carry and store. When in use, the multiple carbon fiber connecting rods 2 can be quickly assembled into a climbing ladder, which is convenient to use. The multiple carbon fiber connecting rods 2 are connected end to end, and the foot pedals 3 are set on opposite sides of the carbon fiber connecting rods and staggered. Compared with traditional climbing ladders, it is smaller in size, making it easier to use in some narrow terrains and more versatile.

[0024] In one feasible solution, the carbon fiber connecting rod 2 includes a carbon fiber rod body 201. One end of the carbon fiber rod body 201 is provided with a second pin hole 204, and the other end of the carbon fiber rod body 201 is fixedly connected to a connecting end 202. The connecting end 202 is provided with a first pin hole 203. The connecting end 202 is inserted into another carbon fiber rod body 201. The second pin hole 204 is correspondingly provided with the first pin hole 203, and the second pin hole 204 and the first pin hole 203 are connected by a quick-release pin.

[0025] The cross-sectional shape of the carbon fiber rod 201 can be polygonal or circular, which can be selected by technicians according to actual needs.

[0026] The two adjacent carbon fiber rods 201 are connected by quick-release pins, which increases the assembly speed of the climbing ladder.

[0027] In one feasible solution, the foot pedal 3 includes a pedal rod 301, which is fixed to the carbon fiber rod 201. The axes of multiple pedal rods 301 are arranged in parallel. A sleeve 303 is fixed to one end of the pedal rod 301 away from the carbon fiber rod 201. A stacking pin is fixed to one end of the sleeve 303. The sleeve 303 is adapted to the stacking pin. The axis of the sleeve 303 is perpendicular to the axis of the carbon fiber rod 201.

[0028] When carried and stored, the sleeves 303 on multiple foot pedals 3 are coaxially arranged, and the multiple sleeves 303 are connected by stacking pins. The multiple carbon fiber rods 201 are stacked sequentially from bottom to top, which is convenient for storage and can effectively prevent the carbon fiber rods 201 from being disordered during storage, thus affecting their use.

[0029] In one feasible solution, a reinforcing rib 302 is provided between the pedal 301 and the carbon fiber rod 201. One end of the reinforcing rib 302 is fixed to the outer side wall of the carbon fiber rod 201, and the other end of the reinforcing rib 302 is fixed to the end of the pedal 301 away from the carbon fiber rod 201.

[0030] The connection strength between pedal 301 and carbon fiber rod 201 is enhanced, while the load-bearing capacity of pedal 301 is increased.

[0031] In one feasible solution, the support base 4 includes two support rods 401, both of which are fixed to the outer wall of the carbon fiber rod 201. The two support rods 401 are symmetrically arranged, and the end of the support rod 401 away from the carbon fiber rod 201 abuts against the wall.

[0032] One end of the support rod 401 is abutted against the wall, leaving a gap between the carbon fiber rod 201 and the wall, making it easier for workers to climb by stepping on the foot bar 301.

[0033] In one feasible solution, one end of the hook 1 is hinged to the mounting groove by a bolt 103. The mounting groove is opened at the end of the connecting sleeve 102 away from the carbon fiber rod 201. The connecting sleeve 102 is detachably connected to the connecting end 202 located at one end.

[0034] This design makes it easy to remove hook 1 for inspection and maintenance.

[0035] In one feasible solution, two U-shaped brackets 104 are fixedly connected to the end of the connecting sleeve 102 away from the carbon fiber rod 201. The two U-shaped brackets 104 are symmetrically arranged and located on opposite sides of the mounting groove. The open end of the U-shaped bracket 104 faces the carbon fiber rod 201. A fixing rod 105 is fixedly connected between the ends of the two U-shaped brackets 104. One end of a spring 106 is sleeved on the fixing rod 105, and the other end of the spring 106 is sleeved on the hook ring 107. The hook ring 107 is fixedly connected to the hook 1.

[0036] This design prevents the hook 1 from moving without external force when not in use, thus avoiding messy storage. When in use, the angle between the hook 1 and the carbon fiber rod 201 changes as the terrain changes and workers climb, ensuring that the force on the carbon fiber rod 201 is always along the axial direction of the carbon fiber rod 201, thus guaranteeing the service life of the carbon fiber rod 201. At the same time, it ensures that the hook 1 will not flip backward when hooking an object.

[0037] Specific assembly method:

[0038] Insert the connecting end 202 on the carbon fiber rod 201 into another carbon fiber rod 201. The second pin hole 204 is set to correspond with the first pin hole 203. Insert the quick release pin into the second pin hole 204 and the first pin hole 203 to fix the two adjacent carbon fiber rods 201 together. Repeat this process several times. Insert the connecting end 202 of the carbon fiber rod 201 located at one end into the carbon fiber rod 201 connected with the hook 1. Connect it with the quick release pin to complete the assembly.
