高度較高，則需使用較長之梯子，如此，造成梯子 的收納困難且體積魔大。 '而後A現對折式之梯子，將梯子中間斷開並 並於其側邊分別以一安+卢；拉 祕7 女王杯連接，使用時展開而使 梯子呈現A字#ί，1 τ· 為市面上常見之折合梯。但此種 折合梯通常只以安全桿來 枰來固疋梯子，若於攀爬時他 成立到梯子’梯子很容易收合而令使用者跌落造 ^外。騎合梯之梯階依然無法配合使用者需求 而做調升，若可5 上

New description: [New technical field] This creation is about the improvement of the extension ladder, especially the extension ladder structure which can be changed according to the user's needs and added with multiple safety settings. [Prior Art] In the past, when climbing to the height, people used to use the long ladders made of bamboo or wood as an auxiliary tool, but because they are not firmly connected to the ground or the wall, it is easy. An accident that causes the ladder to slide when climbing, and the conventional ladder is a fixed distance that cannot be adjusted with height. If the height of the climb is high, a longer ladder is required, which makes the storage of the ladder difficult and bulky. 'After A, the ladder is folded, the middle of the ladder is broken and the side is separated by an An + Lu; the secret 7 Queen Cup is connected, and when used, the ladder is presented with the A word #ί,1 τ· A common folding ladder on the market. However, such a folding ladder usually only uses a safety rod to secure the ladder. If it is set up to climb the ladder when climbing, the ladder is easy to fold and the user is allowed to fall. The steps of the riding ladder are still unable to adjust to the user's needs. If the folding ladder is more than 5, the volume after folding is still quite large. In order to improve the above problems, the company has developed a retractable erect that can pull the steps up to a higher position and has a smaller volume when stored. However, at present, the safety setting of such an extension ladder is still not in contact with the wall surface or contact with the ground - the preferred safety setting is such that the extension ladder is not easy to slide when climbing. Moreover, the folding method of the extension ladder easily causes the step to suddenly drop and pinch the user. In summary, the traditional telescopic ladder safety setting is insufficient, and the way of accommodating the steps is not ideal, and it is currently folded-equivalent to the extension ladder-like free stretching, and the way of the ^ is also ^ firmly θ in order to solve the above problem The creator of this creation must conceive a telescopic ladder structure that can change the use of the extension ladder according to the user's needs and enhance the safety of the extension ladder. [New content] One of the purposes of this creation is to provide a telescopic ladder structure to improve the safety of the use of the extension ladder. This creation utilizes the lowering slides of the upper and lower slides and the extension slides to enhance the safety of the extension ladder. The upper stop slide can increase the resistance of the two telescopic ladder structures to the wall surface and the pole when placed on the wall or the pole. The upper sliding portion is disposed through the connecting portion, and is disposed on the pair of uprights, wherein the hollow rods of the pair of maximum diameters are a rectangular plate or a circular arc shaped opening is formed on the rectangular plate. Wherein, the circular arc opening can make the upper sliding sliding portion more conform to the cylinder such as the column rod, and even if applied to a plane such as a wall surface, the two sides of the circular arc opening can be utilized as the force against the wall surface. In order to make the telescopic ladder structure and the wall surface have greater resistance when climbing, the telescopic ladder structure does not slide easily. The lower sliding portion includes a 4k rod and two sliding members, and the two sliding members are disposed on both sides of the rail. The cross bar is fastened to the bottom end of the hollow rods by rivets, so that the sliding blocks can contact the ground, so that when the telescopic ladder structure is placed on the ground, high resistance can be generated with the ground to prevent the expansion and contraction when climbing. The sliding structure of the ladder structure can enhance the safety of the extension ladder when it is used. In addition, the present invention is provided with a plurality of push buttons on a plurality of horizontal plates for use as pedals. When the extension ladder structure is accommodated, the user must simultaneously push the push buttons to fold the telescopic ladder structure. This design can avoid pushing only one of the push buttons during storage, and the hollow rods connected to both sides of the horizontal plates can directly slide, causing the horizontal plates to fall and hit the user's hand and cause injury. Or when one of the push buttons is accidentally touched by someone else or by themselves, the hollow rods slide and cause an accident. Another object of the present invention is to provide a telescopic ladder structure that allows the telescopic ladder to be used in response to user needs, and that is safe to use without slipping. The telescopic ladder structure of the present invention is provided with a folding mechanism and an unlocking mechanism. Through the folding mechanism, the user can pull the two pairs of poles to fix the extension ladder structure at an angle for use as an A-shaped ladder. The two pairs of poles can also be pulled to a state of 180 degrees for use as an upright ladder. When the two pairs of poles are pulled to a specific angle, the engaging blocks in the folding mechanism are caught in the slots, so that the two pairs of poles can no longer be pulled to be in a fixed state for the user to climb. If it is necessary to change the angle of the second pair of opposing poles, the corpse needs to pull the lever in the unlocking mechanism to cause the sliding piece M438534 to push the engaging block away from the slot to pull the second opposing pole β for the above purpose. The creation of the two pairs of vertical rods is composed of a plurality of hollow rods, and the tubes of the hollow rods are gradually reduced in the radial direction, wherein the hollow rods of the smaller diameters can be accommodated in the larger diameter of the tubes. The hollow blade has a first button hole; a plurality of horizontal plates are disposed on the top end of the hollow rods and the plurality of grooves are formed on the surface of the horizontal plates The two (four) of the horizontal plates are respectively connected with the middle portion by a connecting portion, and the connecting portion is a sleeve, and the sleeve is sleeved on the hollow rods. The sleeve is connected to the 2 horizontal plate by a rivet, and corresponding to the first button hole is provided with a second button hole. The invention has at least one apron at the top of the connecting portion. When the telescopic ladder structure is to be accommodated, the aprons can avoid direct collision with each other when the hollow rods slide, and can effectively reduce the buffering force and reduce Noise during storage. The inside of the k-plate is provided with two slots, and the two slots are respectively provided with a positioning rod and an elastic component, and the positioning rod is buckled by the elastic component to the first fastening hole. The positioning rod is provided with a connecting rod extending to the outside of the horizontal plate and combined with a push button, wherein each push button is pushed at the same time to drive the positioning rods in the two sockets, so that the positioning rods are contracted Within the transverse plate, the hollow rods are moved. a folding mechanism is disposed at the top end of the two opposite ends, so that the pair of vertical rods can be fixed at different angles, and includes two joints, which are respectively connected to the two pairs of vertical rods by using a connecting shaft, and the two The joints respectively comprise a circular plate and a snap block; wherein, when the round-to-V-slots are engaged in the slots, the two pairs of poles are in a fixed state. The β-unlocking mechanism is disposed on the folding mechanism, and includes a pull/pull rod connecting shaft and two sliding pieces, and the two ends of the pulling rod and the two sliding piece systems are respectively connected to the folding mechanism through the connecting rod connecting shafts. When the pull rod is pulled, the sliding sheets respectively push the engaging blocks away from the slots. An upper sliding portion is disposed on the hollow rods of the pair of upright rods, wherein the pair of upper sliding rods are disposed on the hollow rods; and the lower sliding portion is disposed in the two pairs of vertical rods The bottom end of the hollow rods relative to the largest diameter of the upper sliding portion. The upper sliding portion is a rectangular plate or a rectangular plate and is provided with a circular arc opening, and the circular arc opening is located on the side of the telescopic ladder structure against the wall surface or the column. The lower sliding portion includes a cross bar and two sliding members, and the two sliding members are disposed on both sides of the cross bar. Further, the present invention further has a storage belt which is provided on the fascia, and the accommodating belt is provided with a devil felt for being attached and fixed during storage.
