Creation Instructions (1) [The original creation of this creation is true and easy. [Previous skill buttons, ladders, or scaffolding, etc. are mounted on high-level connections, and the tradition of proper distances can also be retracted. In view of the creation of Yu Youben [this creation, it is another purpose for the multi-section ladder to be brought by hollow ladders, collected, or based on the original kit. According to the cover of the wound board, the ladder rack for the articles at the high appliances, the pedals under the ladder posts, and the type ladder rack need to occupy this. The content of this book is stretched to make this clamp. Rear tools, such as ladders, can be quickly obtained or are separated from each other by two ladder columns, which can be carried without much improvement. In the end, the telescopic ladder is structured so that each section of the ladder column can be easily folded. Bringing hollow ladder tubes and connectors is the scope of this creation. Tongguan—A kind of telescopic ladder, especially refers to those with a more stable assembly structure and a telescopic ladder structure with better safety. Use has become indispensable to people ’are to provide effective tools that people can easily. As shown in Figure 1, foot pads at the 800 ° end of the ladder frame are provided to prevent slipping, and are A-shaped for use during use. Due to its large overall volume and large space, the lack of flexibility in use is to address these shortcomings. The creator is to provide a telescopic ladder structure, horizontal ladder plate and locking mechanism group heads and connection kits, such users. This kind of telescopic ladder structure, its sleeve and re-adhesive fixing, this kind of telescopic ladder structure can be easily loosened, and its connection kit is also horizontal to avoid rust damage, which is another purpose of the creation.

Creative Instructions (2) Zhao Xia == Detailed structure, application principle, function and effect, then please refer to the description given in the drawings to get a complete understanding. [Implementation of this creation] For this kind of telescopic ladder structure, the telescopic ladder 1 can be collapsed (as shown in Fig. 2), "is opened (as shown in Fig. 3), and includes Most of the first and horizontal ladder plates 3 and the locking mechanism 4 are high-rise ladder frames when they are in use. When they are collapsed, they are superimposed by each ladder column unit. P ^ mad morning 70 is a non-diameter setting and can be similar to that shown in Figs. 4 and 5. The ladder column unit 2 is composed of a hollow ladder tube 21 and a socket head joint member 23. Each hollow ladder tube 21 The higher the position, the smaller the pipe diameter. The upper end is formed with a ring-shaped groove 211, a hemispherical tenon 212 and a hole 213. A lower part is provided with a through hole 214, and a sleeve 22 is sleeved on the upper end of each hollow ladder tube 21; 22 is a ring shape, and the outer sleeve is provided with a connection set 23, which is provided with an inner convex ring 221, a convex particle 222 and an expansion joint 223 at positions corresponding to the annular ladder groove 211, the hemispherical tenon 212 and the hole 213 Butt, the bottom end is provided with an outwardly protruding outer edge 224, and the inner and outer pipe wall surfaces are concavely provided with viscous flow channels 225, 226, which communicate with each other through a through hole 227, and The top end of the sleeve 22 is provided with an inner ring edge 228 extending inward (as shown in FIG. 6). The connection kit 23 has a sleeve pipe 231 for covering the sleeve, and two upright connecting plates 2 3 2 which are arranged in the radial direction of the sleeve pipe and are parallel to each other. The pipe wall of the sleeve pipe 2 31 is provided with The opposite hole 2 3 3 is used for injecting the adhesive, and the pipe periphery is further provided with a fixing hole 234 between the connecting plates 232. The locking mechanism 4, as shown in the figure, includes a lock 41, a lock lever 42, a spring 43 and a lever 44; the lock 41 has hook ends 411 on both sides of its front end, M248901 5. Creation instructions (3) The connecting plate 232 of the connection kit can be interlocked, and its inner rear end has a spring slot for receiving the spring meal 43, so that the end of the lock lever 42-against the spring 43 is directly opposite the connection kit. The locking hole 234, and the lock lever 42 is a middle shaft 421 for the lever 44 to be forked by the lever 44. The lever 44 is sleeved to the lock with its lower shaft 441 The groove 412 is predetermined so that it rotates around the chuck shaft 441. The horizontal ladder plate 3 is sleeved on the outside of the locking mechanism 4, and a through hole 31 is formed at the lower end thereof for the lever 44 to extend. In addition, 'the hollow ladder tube 21 is provided with a buffer element 5 at the lower end, and the buffer element 5 is slightly sleeve-shaped'. The upper end thereof is hooked with a hook 5 and fixed to a preset button hole 5 2 of the ladder tube. The elastic sealing ring 53 is provided for maintaining friction when contacting the inside of the ladder tube to reduce noise and buffer collapse. As shown in FIG. 6, a hole is formed on the surface of the adhesive film W ′ and the adhesive film 54, so that when the buffer element 5 moves up and down with the ladder tube, air can enter and exit through the hole to promote the buffer effect. . After the assembly is completed, as shown in the figure, the hollow ladder tube has buffer elements 5 and elastic sealing rings 53 at the bottom end, which can increase the contact friction with the inner tube wall of the outer ladder tube to achieve the purpose of buffering and lifting; The sleeve 22 can be injected through the mucus flow channels 225, 22 6 to inject adhesive to make it tightly adhered to the ladder tube 21 and the connection kit 23, so it is extremely safe and stable after the entire assembly is completed; the locking mechanism 4 and Because it is completely enclosed inside the lateral ladder plate 3, it is not only convenient to control, but also can avoid damage caused by the penetration of foreign objects. When used for stretching, the fixing hole 214 in the lower section of the internal hollow ladder tube is fixed by the locking rod 42 assembled to the external hollow ladder tube. When the locking rod 42 is withdrawn, the internal hollow ladder tube will automatically lower and close. . For the convenience of explanation, different figures are used below. When collapsed, as in Section 7

Seeing the lack of a ladder, I would like to ask those who are in need of Chen Ming to follow the instructions and illustrations created by this Chen Ming. The hole and the first joint descended to the force, and the three-story ladder was completed quickly. The original user was lost, and the benefit was realized, which is covered by the above concept. 丨 ~ Yangnu b 1's lever 6 2 goes through the hole back ladder. The plate 6 5 down the lever 6 6 touches, which drives its three-story horizontal ladder and the ladder board to the telescopic ladder structure effect. These openly use the two-story ladder tube * one layer to make its lower end turn clockwise 68 and the first This kind of work done quickly is not seen as a virtue. The above mentioned is the spirit of change when the younger layer is dropped, and the lock plate 6 9 on the first layer of the field is smoothly stacked down and received. It is indeed effective, combined with the speciality, and drives the lock ladder tube 6 4 that is the second The floor is horizontal. Exit to the ladder 6 1 and the pole 6 7 to drop and close. There are improvements that can improve the rules of profit law. This is a better and concrete embodiment of this creation, and the functional effects produced by it are not beyond t ’s, which should be within the scope of this creation.
