Eagle frame extension function ladder

This creative department is related to the scaffolding, especially a scaffold extension function ladder that can enhance its safety and convenience when working on a scaffold.

With the advancement of society and the rapid development of industry and commerce, buildings have sprung up everywhere, and in the process of constructing larger buildings, the metropolis has set up a eagle frame for construction workers to walk on and climb up. In order to assist the construction; however, the construction workers are required to construct on the scaffold with limited space, frequent personnel movements and construction workers are responsible for tools and materials. Therefore, there is concern that the construction workers may have a risk of falling accidents, resulting in the cost of the scaffolding. The structure evolved from the early bamboo frame to the current construction of steel pipes and other materials, in order to increase the rigidity of the scaffold structure, so that when there is an earthquake or strong wind, it can still maintain a certain structural strength to achieve a more complete safety. Protection; however, the current construction workers are directly stepping on the crossbar of the scaffold when they are working up and down, so as to climb the higher level or the lower level, which is not only extremely inconvenient but also lost. The danger of falling.

The reason is that in order to improve the current situation of the construction workers in the upper and lower eagle, a new patent No. M411453 of the Republic of China reveals a telescopic ladder structure for the scaffold, which is mainly near the top of the two sides. Perforation is provided on the side, and two telescopic cannulas are additionally added; the upper end of the second telescopic cannula is welded with a buckle, and the bottom end of the tube wall is provided with a long groove perforation, and the two sides are inserted into the two side long rods from top to bottom. In the middle, the rivet is passed through the perforation and the long groove perforation to give the riveting joint, so that the two telescopic cannula and the upper buckle can cooperate with the upper and lower two horizontal bars of the scaffold to easily lengthen and shorten the hook positioning. According to this, the precision of the upper and lower crossbars of the scaffold is more abundant, and the manufacturing is convenient and fast, so as to save a lot of manpower and time.

However, although the above-mentioned conventional technology can provide the expected function of assisting the construction personnel to climb, this conventional technology still has a long extension length and does not have a hidden ladder and takes up space, in case of a long climbing distance. At the time, it is easy to have problems such as inconvenience and lack of security.

This creation is mainly based on the problem that the conventional technology has a long extension length and does not have a hidden ladder, resulting in inconvenience and lack of safety.

Therefore, in order to solve the above problems of the prior art, the present invention provides a scaffold extension function ladder, which comprises: a frame body and a ladder body; wherein the frame body has at least two parallel frame materials, and the two parallel frame materials are opposite. The side of the system is provided with a sliding slot, and the ladder system has a certain length and can be slid between the two sliding slots for the upward movement and storage of the frame.

At least one connecting rod is disposed between the two parallel frame materials.

The two parallel frame materials are provided with a hook at least at one end.

The above-mentioned ladder body is pivotally provided with a plurality of pedals.

The pedals are provided with a link mechanism.

One end of the ladder body extending from the frame is provided with a hook.

Therefore, the specific focus of this creation and its effects are:

First, the pedals in this creation are pivoted and matched with the design of the linkage mechanism to have the benefit of the invisible ladder.

Second, because the frame of this creation is equipped with a hook structure, in addition to the security of gaining use, it also has the advantage of not occupying space.

Third, because the ladder system in this creation can be stored in the frame, the creation has multiple benefits such as convenient extraction, good useability, easy placement and strong stability.

4. Since the frame and ladder system of this creation can be made of aluminum alloy material, it has the characteristics of high strength and not easy to be deformed.

5. Because the structure of this creation has the design of extended function, it can be used for the use of the construction scaffold.

Referring to the first to fourth figures, a preferred embodiment of a scaffold extension function ladder includes: a frame body (1) and a ladder body (2); wherein the frame body ( 1) having at least two parallel frame materials (11), and a plurality of connecting rods (12) are disposed between the two parallel frame materials (11), so that the two parallel frame materials (11) can be connected into one body, and the The opposite sides of the two parallel frame materials (11) are provided with a sliding groove (13), and at least one end of the two parallel frame materials (11) is provided with a hook (14); and the ladder body (2) has a certain length. And sliding between the two sliding grooves (13) of the frame body (1), so that the frame body (1) is extended and stored, and the ladder body (2) extends out of the frame body ( 1) is provided with a hook (21) at one end, and the ladder body (2) is pivotally provided with a plurality of pedals (22), and a connecting rod mechanism is arranged between the pedals (22) (not shown) ), by which the pedal (22) is pivoted or hidden in the ladder body (2).

Continuing to refer to the first to fourth figures, when the embodiment is used, the ladder body (2) is first pulled out from the frame body (1) to a desired length, and then the frame is used. The hook (14) of the body (1) and the hook (21) of the ladder body (2) are respectively connected to the eagle frame, and the link mechanism is pulled to pivot the pedal (22), and then the construction The person can directly step on the pedal (22), and can safely climb the upper scaffold; according to the above, since the frame (1) and the ladder body (2) have hooks in the embodiment (14) The structure of the hook (21) has safety in use, and the ladder body (2) can be accommodated in the frame body (1), and has convenient extraction, good useability, and easy placement. And multiple benefits such as strong stability.

The above is only the preferred embodiment of the present invention, and is not intended to limit the characteristics of the present creation. The re-creation of the technical means and the creation principle related to the creation is still the creation scope of the creation, and therefore The descriptions of the drawings and the descriptions of the specification are not intended to limit the scope of the present invention; any variations and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should be covered by the invention. Within the scope, the party is reasonable.
