[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0025] Example 1

[0026] Reference Figure 1 , which is the first embodiment of the present invention, provides an insulating ladder, which includes a suction cup 100, a ladder body 200 and a base 300.

[0027] Specifically, the base 300 includes a chassis 301 and a sleeve 302. The two legs at the bottom of the ladder body 200 can be placed in the sleeve 302, so that the installation between the base 300 can be completed. The angle between the chassis 301 and the sleeve 302 can be adjusted, and can be fixed after adjustment. In this way, no matter what angle the ladder body 200 is against the wall, the chassis 301 can be placed flat on the ground. Compared with the legs of an ordinary ladder placed directly on the ground, the present invention has a larger contact area and can prevent the bottom of the ladder from sliding back.

[0028] The suction cup 100 is an electric suction cup and is provided with two suction cups, which are flexibly connected to the top of the ladder body 200. After the ladder body 200 is placed, the personnel climb up the ladder body 200 and suck the suction cup 100 on the wall or other planes, thereby preventing the ladder body 200 from sliding down.

[0029] Example 2

[0030] Reference Figure 1 to Figure 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0031] Specifically, the suction cup 100 is an electric suction cup, which is connected to the ladder body 200 through a metal universal hose, and the metal hose has a certain length. The main reason why the suction cup 100 is connected to the ladder body 200 through a metal hose is that when the ladder body 200 is used, the contact point between the upper end of the ladder body 200 and the wall is subjected to a large force, especially when tilted and external force is applied. If the suction cup 100 is directly fixed on the top of the ladder body 200, any small offset or uneven force may cause stress to be concentrated at a certain point, increasing the risk of damage to the connection point. The use of a universal hose connection allows the suction cup 100 to self-adjust on the contact surface, disperse the force applied to it, reduce the single-point force, and thus extend the service life of the equipment. On the other hand, when the suction cup 100 is an electric suction cup, the electric suction cup will have a certain vibration when it is running. If it is rigidly connected to the ladder body 200, its vibration will be transmitted to the ladder body 200, thereby affecting the user experience.

[0032] The design of the universal hose allows the suction cup to have more freedom when contacting the wall, reducing users' concerns about fixation and allowing them to focus more on work rather than safety issues. The flexibility of the universal hose allows designers to easily add sensors or automatic adjustment systems to future products. For example, if the ladder needs to adapt to different heights or angles, the universal hose can support more mechanical structures without having to worry about the limitations of fixed connections.

[0033] The universal hose design does not require very strict tolerance requirements for the connection between the suction cup 100 and the ladder body 200. Even if the manufacturing accuracy of the upper end of the ladder body 200 deviates, the universal hose can adapt to maintain a good suction effect. This simplifies the production process and assembly process to a certain extent and reduces costs.

[0034] The design of the metal universal hose can effectively reduce the vibration transmitted from the bottom of the ladder to the suction cup. This vibration reduction effect can make the suction cup more stable on the contact surface, thereby reducing adsorption failure caused by vibration and ensuring safety during operation.

[0035] The flexibility of the universal hose means that the suction cup can not only be used to fix the ladder, but also provide support when the user needs to temporarily fix other items. For example, on a construction site, users can use the suction cup to fix tools, equipment, etc., which improves the versatility and economic benefits of the ladder. This design not only improves user convenience, but also opens up new market applications for product development.

[0036] Furthermore, a first toothed disc 301a is fixed to one side of the top of the chassis 301. The first toothed disc 301a is circular, and a circle of latching teeth is evenly arranged on one side thereof, with gaps between the latching teeth. In contrast, a second toothed disc 302a is also fixed to the bottom of the sleeve 302. The second toothed disc 302a has the same shape as the first toothed disc 301a. The second toothed disc 302a also has latching teeth arranged on its side. The first toothed disc 301a and the second toothed disc 302a can mesh with each other. When the two mesh, the two cannot rotate relative to each other.

[0037] A first fixing rod 303 is also provided in the axial direction of the first toothed disc 301a and the second toothed disc 302a. A first knob 303a is installed at one end of the first fixing rod 303 close to the first toothed disc 301a. A first lock buckle 303b is hinged at one end of the first fixing rod 303 close to the second toothed disc 302a. The place where the first lock buckle 303b is hinged to the first fixing rod 303 is not a standard circle, but a cam shape. A first pressing cap 303c is also installed between the first lock buckle 303b and the second toothed disc 302a. The first pressing cap 303c is sleeved on the first fixing rod 303 and slidably cooperates with it. When the first lock buckle 303b is bent, its end can squeeze the first pressing cap 303c to make it move. A spring is also provided between the first toothed disc 301a and the second toothed disc 302a, and the spring provides a certain tightening force and reset.

[0038] The sleeve 302 is a hollow cylinder, with a notch on the top side wall, and a hoop 303e sleeved on the outside. A second fixing rod 303f, a second knob 303g, a second lock 303h and a second pressure cap 303i are provided at the opening connection of the hoop 303e. One end of the second fixing rod 303f is threadedly matched with the second knob 303g, and the other end is hinged with the second lock 303h. One end of the second pressure cap 303i abuts against the hoop 303e, and the other end abuts against the second lock 303h. The shape of the second lock 303h is the same as that of the first lock 303b. After the second lock 303h is opened and rotated, the hoop 303e can be tightened or loosened.

[0039] Example 3

[0040] This is the third embodiment of the present invention, which is based on the first two embodiments. This embodiment provides a method for using an insulating ladder.

[0041] When in use, first install the two legs at the bottom of the ladder body 200 in the sleeve 302. Then lift the second lock 303h and rotate it to tighten the hoop 303e, thereby fixing the hoop 303e to the bottom of the ladder body 200, and then buckle the second lock 303h back after tightening it.

[0042] Then, lift the first lock buckle 303b and rotate it to move the first toothed disc 301a and the second toothed disc 302a away from each other, then adjust the angle between the chassis 301 and the sleeve 302 so that the chassis 301 is placed flat on the ground, and then rotate the first lock buckle 303b in the opposite direction so that the first toothed disc 301a and the second toothed disc 302a are engaged, so that the angle between the chassis 301 and the sleeve 302 remains fixed.

[0043] Then the worker climbs up the ladder body 200, and when reaching the top, he or she adsorbs the suction cup 100 on the wall or other adsorbable plane to complete the fixation.

[0044] In summary, the present invention increases the contact area between the bottom of the insulating ladder and the ground through a rotatable stable base, thereby making it more stable when in use. At the same time, the safety of the top of the insulating ladder is improved through an electric suction cup to prevent it from tipping over, thereby ensuring the stability and safety of the insulating ladder when in use.
