Technical Field

[0001] The utility model relates to the technical field of ladders, in particular to a foldable carbon fiber ladder. Background Technique

[0002] A carbon fiber ladder is a ladder made of carbon fiber material. The carbon fiber material is very light and has extremely high strength and rigidity, making the carbon fiber ladder lighter and more durable than traditional aluminum alloy or steel ladders. Moreover, carbon fiber also has good corrosion resistance and is less likely to rust or corrode than metal ladders when used in humid or harsh environments. And due to the strength and rigidity of carbon fiber, the stability and load-bearing capacity of the ladder are relatively high, making it safer to use.

[0003] The carbon fiber ladder is made of carbon fiber material, which has extremely high strength and rigidity, and carbon fiber has good corrosion resistance, making the stability and load-bearing capacity of the ladder relatively high, safer to use, and not easy to rust or corrode. When a staff member moves or sways on the ladder, it is easy to change the center of gravity on the ladder, and the movement of the staff member causes uneven force on the ladder, thus affecting the stability and angle of the ladder and easily causing the ladder to tilt. Therefore, we propose a foldable carbon fiber ladder. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A foldable carbon fiber ladder, including a ladder main body and a bracket. The outside of the ladder main body is movably connected to the bracket through a rotating shaft, and a chute is opened on one side of the ladder main body. The chute is slidably docked with a slider, and one side of the slider is movably connected to one end of a connecting rod through a rotating shaft. The end of the connecting rod away from the slider is movably connected to the bracket through a rotating shaft, and a storage groove is opened inside the slider.

[0006] Preferably, the storage groove is slidably docked with a tooth block, and a bolt penetrates through the slider.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the foldable carbon fiber ladder, the ladder body and the bracket are respectively made of carbon fiber materials. When the carbon fiber ladder is placed on the ground for use, the bolt is rotated to disengage the tooth block from the tooth plate. At this time, the staff rotates to open the folded and retracted ladder body and bracket, and then rotates the bolt to push the tooth block to engage with the tooth plate, so that the slider is restricted to the inside of the slide groove, so that the rotation angle between the ladder body and the bracket is fixed, so that when the staff moves or shakes on the carbon fiber ladder to change the center of gravity, it is not easy to change the opening angle of the ladder, and it is not easy to cause the ladder to tilt.

[0018] 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.

[0019] See also Figures 1-4, the present utility model provides a technical solution: a collapsible carbon fiber ladder, including a ladder main body 1 and a bracket 101. The outer side of the ladder main body 1 is movably connected to the bracket 101 through a rotating shaft. A chute 2 is provided on one side of the ladder main body 1. The chute 2 is slidably docked with a slider 201. One side of the slider 201 is movably connected to one end of a connecting rod 202 through a rotating shaft. The end of the connecting rod 202 away from the slider 201 is movably connected to the bracket 101 through a rotating shaft. A storage groove 203 is provided inside the slider 201. The storage groove 203 is slidably docked with a tooth block 204. A bolt 205 penetrates through the inside of the slider 201. One end of the bolt 205 is movably connected to the tooth block 204 through a bearing. The tooth block 204 is docked with a tooth plate 206. The tooth plate 206 is fixed to the ladder main body 1. The lower ends of the ladder main body 1 and the bracket 101 are respectively movably connected to a support plate 207 through a rotating shaft. A connecting pad 208 is bonded to the lower side of the support plate 207. The connecting pad 208 is made of rubber material. The chute 2 matches the slider 201. The storage groove 203 matches the tooth block 204. The slider 201 is threadedly connected to the bolt 205. The tooth block 204 is meshed and docked with the tooth plate 206. The ladder main body 1 and the bracket 101 are respectively made of carbon fiber material.

[0020] During specific implementation, according to Figures 1-4 , the ladder main body 1 and the bracket 101 are respectively made of carbon fiber material, making the carbon fiber ladder have extremely high strength, rigidity and good corrosion resistance, making the carbon fiber ladder safer to use. When the carbon fiber ladder is placed on the ground for use, rotate the bolt 205. Due to the threaded connection between the slider 201 and the bolt 205, the bolt 205 can drive the tooth block 204 to slide along the storage groove 203. Through the matching of the storage groove 203 and the tooth block 204, the tooth block 204 can be stably received inside the slider 201, so that the tooth block 204 is disengaged from the meshing connection with the tooth plate 206. At this time, the staff rotates to open the folded and retracted ladder main body 1 and the bracket 101, so that the slider 201 slides along the chute 2. Through the matching of the chute 2 and the slider 201, the slider 201 is not easy to shake when moving. The support plate 207 of the ladder main body 1 and the support plate 207 of the bracket 101 are respectively placed on the upper side of the ground. Since the connecting pad 208 is made of rubber material and has a certain deformation ability, it can strengthen the friction between the support plate 207 and the ground. At this time, rotate the bolt 205 again, so that the bolt 205 pushes the tooth block 204 to be meshed and docked with the tooth plate 206, so that the tooth block 204 and the tooth plate 206 are restricted together, and the slider 201 is restricted inside the chute 2, so that the rotation angle between the ladder main body 1 and the bracket 101 is fixed. When the staff moves or shakes on the carbon fiber ladder to change the center of gravity, it is not easy to change the opening angle of the ladder and it is not easy to cause the ladder to tilt.

[0021] To sum up, the ladder body 1 and the bracket 101 are made of carbon fiber materials respectively. When the carbon fiber ladder is placed on the ground for use, the bolt 205 is rotated to disengage the tooth block 204 from the tooth plate 206. At this time, the staff can rotate open the folded and retracted ladder body 1 and bracket 101, and place the support plate 207 of the ladder body 1 and the support plate 207 of the bracket 101 on the upper side of the ground respectively, and then rotate the bolt 205 to make the bolt 205 push the tooth block 204 to engage with the tooth plate 206, so that the slider 201 is restricted to the inside of the slide groove 2, so that the rotation angle between the ladder body 1 and the bracket 101 is fixed, so that when the staff moves or shakes on the carbon fiber ladder to change the center of gravity, it is not easy to change the opening angle of the ladder, and it is not easy to cause the ladder to tilt. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
