Description

Technical Field

[0001] The utility model relates to the technical field of stairs, and more specifically to a novel flip-type telescopic staircase. Background Art

[0002] With the continuous development of the construction industry, attics in buildings are becoming more and more common. In daily life, we often see houses with attics in cities. Most attics are either idle or used to store food or some infrequently used items. People usually use attics by moving ladders and then going up to the attic, which is not only inconvenient and laborious, and they may even hit the furnishings of the house in the process of moving the ladder.

[0003] In order to solve the above problems, a retractable staircase has been developed. When not in use, it can be folded and hidden in the ceiling or wall to save space. When the loft space is needed, it can be unfolded into a complete staircase for people to go up and down. However, the current retractable staircases, especially the manual retractable staircases, have poor stability when in use. When the retractable staircase is retracted to the loft entrance, if there is no lock to limit the retractable plate, the retractable plate will open uncontrollably and cause accidental injuries to the user.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1 , 2 The invention discloses a novel flip telescopic staircase, comprising a telescopic ladder body 1, a fixed frame 2 and a flip plate 3. The fixed frame 2 is installed at the attic opening adapted thereto. The flip plate 3 is adapted to the fixed frame 2 and is hinged thereto through a hinge. The telescopic ladder body 1 adopts a connecting rod type telescopic structure. The flip plate 3 is provided with a connecting mechanism 4 of the telescopic ladder body 1. The connecting mechanism 4 is hinged to the telescopic ladder body 1. The connecting mechanism 4 comprises two hinge seats 41 fixedly installed on the upper end of the flip plate 3. The upper ends of the telescopic ladder body 1 are respectively hinged to the two hinge seats 41. Sliding rods 42 are fixedly installed on the flip plate 3 and located below the two hinge seats 41. Connecting rods 43 are hinged on the two sliding rods 42. The other ends of the two connecting rods 43 are respectively hinged to the two sides of the telescopic ladder body 1. Auxiliary rods 44 are provided on the outer sides of the two sliding rods 42. A sliding assembly 45 slidably connected thereto is provided on the sliding rod 42. The sliding assembly 45 is rotatably connected to the auxiliary rod 44. The other end of the auxiliary rod 44 is rotatably connected to the long side of the inner wall of the fixed frame 2.

[0023] The above structure can be used after the fixing frame 2 is fixedly installed in the attic installation opening adapted thereto. When entering the attic, the flip plate 3 is opened and the telescopic ladder body 1 is lowered. After leaving the attic, the telescopic ladder body 1 is folded up and the connecting mechanism 4 is used to prevent the telescopic ladder body 1 from bouncing open. It is no longer necessary to manually carry the ladder to enter the attic, which brings great convenience.

[0024] Reference Figure 1 , 2The sliding assembly 45 includes a slider 451. The sliding rod 42 is a hollow structure. The slider 451 is arranged in the sliding rod 42 and is slidably connected thereto. The slider 451 is adapted to the inner cavity of the sliding rod 42. A strip-shaped movable opening 452 is provided on the outer side of the sliding rod 42. A connecting column 453 adapted thereto is inserted in the strip-shaped movable opening 452. One end of the connecting column 453 is fixedly connected to the auxiliary rod 44, and the other end is rotatably connected to the slider 451.

[0025] During the process of opening or closing the flip plate 3, the auxiliary rod 44 can move on the slide bar 42 through the cooperation of the sliding assembly 45. When the flip plate 3 and the telescopic ladder are fully unfolded, the auxiliary rod 44 is driven by the slider 451 to move to the highest point of the strip-shaped movable opening 452, and cooperates with the auxiliary limit of the connecting column 453 and the strip-shaped movable opening 452, so that the auxiliary rod 44 generates a thrust on the flip plate 3, forms a limit mechanism for the flip plate 3, and then forms a stable support structure between the flip plate 3, the connecting rod 43 and the telescopic ladder 1, thereby increasing the stability of the telescopic ladder 1 when in use.

[0026] When the flip plate 3 and the fixed frame 2 are closed, the auxiliary rod 44 moves to the tail end of the strip movable opening 452 under the action of the sliding assembly 45 and is rotated and folded to be stored in the fixed frame 2, and an upward pulling force is generated on the flip plate 3, thereby effectively preventing the flip plate 3 from opening uncontrollably and spontaneously. The structure has high safety performance, saves manpower, and is easy to use.

[0027] In addition, handrails 5 are fixedly installed on the long sides of the two inner walls of the fixing frame 2, which is convenient for users to go up and down the attic and improves safety. A reinforcing rod 46 is arranged between the two connecting rods 43, and the reinforcing rod 46 is fixedly connected to the two connecting rods 43 respectively. The reinforcing rod 46 is close to the flip plate 3, and the two connecting rods 43 are connected as a whole through the reinforcing rod 46, so as to further improve the stability of the telescopic ladder body 1.

[0028] It is worth mentioning that the retraction and extension of the telescopic ladder can also be controlled by the motor electric push rod. Adding a motor controller can wirelessly control the motor electric push rod, which is more convenient to use. The fixed frame 2 and the flip plate 3 can also be provided with a matching lock tongue and lock to increase stability and safety.

[0029] Example 2

[0030] See also Figure 2, a mounting assembly 6 is provided on the top of the fixing frame 2, and the mounting assembly 6 fixes the fixing frame 2 on the attic. The mounting assembly 6 includes four fixing bolts 61 respectively fixedly installed at the four corners of the top of the fixing frame 2, and the four bolts 61 are sleeved with gaskets 62, and the four bolts 61 are threadedly connected with fastening nuts 63 located above the gaskets 62. Through the mutual cooperation of the bolts 61, the gaskets 62 and the fastening nuts 63, the fixing frame 2 can be quickly installed on the attic table, and the provision of the bolts 61 can also assist in the lifting of the fixing frame 2 before installation.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
