DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 A telescopic bed ladder in this embodiment includes a connecting plate 2, connecting rods 1 are fixed on the upper and lower sides of the connecting plate 2, the top of the connecting plate 2 is movably connected to a driving plate 3, and a placement opening is opened on the top of the connecting plate 2.

[0023] It can be understood that the provision of the placement opening facilitates a hidden design of the drive plate 3, thereby facilitating improved stability of the connecting plate 2 when stepped on, and further facilitating improved overall safety of use.

[0024] The driving plate 3 is slidably connected to the connecting plate 2 through the placement port. Two connecting plates 4 are fixed to the bottom of the connecting plate 2. A driving component 5 fixed to the connecting plate 4 is provided on the connecting plate 2. Both connecting plates 4 are provided with an action component 6.

[0025] In this embodiment, the setting of the driving component 5 releases the limit on the action component 6, thereby realizing the driving of the action component 6 and the lowering of the pedal 606, which is conducive to improving the overall convenience of use.

[0026] See also Figure 2 In order to achieve the extension of the pedal 606, the driving assembly 5 in this embodiment includes a movable block 501 that penetrates into the connecting plate 2 and is fixed to the driving plate 3. A movable opening that is connected to the placement opening is opened on the connecting plate 2. The movable opening penetrates to the bottom of the connecting plate 2. The movable block 501 penetrates into the connecting plate 2 and is slidably connected to the connecting plate 2.

[0027] It can also be understood that the setting of the movable opening is conducive to the sliding of the movable block 501, which is conducive to the stable lifting and lowering of the action plate 504 through the pressing of the drive plate 3, thereby helping to improve the overall stability of use, and further helping to improve the use effect.

[0028] The top of the movable block 501 is fixed to the driving plate 3, and the two connecting plates 4 are fixed with fixed plates 502 on the opposite sides. The movable block 501 passes through the bottom of the fixed plate 502 and is slidably connected with it. The top of the fixed plate 502 is fixed with a supporting spring 503, and the supporting spring 503 is fixed to the outer side of the movable block 501. The left side of the movable block 501 is fixed with an action plate 504, and the left side of the action plate 504 is fixed with an arc block, which fits with the top of the movable shaft 604.

[0029] In this embodiment, the provision of the supporting spring 503 facilitates supporting the movable block 501, thereby facilitating resetting the drive plate 3 and the action plate 504, thereby facilitating stable use of the overall structure and improving stability in use. The provision of the arc block facilitates stable squeezing of the movable shaft 604, thereby facilitating releasing the limit of the movable shaft 604, thereby facilitating extension of the pedal 606, and facilitating overall stable use.

[0030] See also Figure 3 In order to improve the convenience of extending and retracting the pedal 606, the action component 6 in this embodiment includes a rotating shaft 601 rotatably connected between the front and rear connecting plates 4. Both connecting plates 4 are provided with rotating holes, and the rotating shaft 601 is rotatably connected to the connecting plates 4 through the rotating holes.

[0031] It should be noted that the provision of the rotating hole is conducive to the stable rotation of the rotating shaft 601, thereby facilitating the improvement of the overall convenience of use.

[0032] A rotating shell 602 located between the two connecting plates 4 is fixed to the outside of the rotating shaft 601, and a return spring 603 is fixed to the outside of the rotating shaft 601. A movable shaft 604 is slidably connected between the two connecting plates 4, passing through the rotating shell 602 and fixed to the left end of the return spring 603. Moving openings are opened on the front and rear side surfaces of the rotating shell 602, and the movable shaft 604 is movably connected to the rotating shell 602 through the moving openings.

[0033] The setting of the return spring 603 is conducive to pulling the pedal 606, thereby providing elastic force when the pedal 606 slides upward and is retracted, which is conducive to the rapid and convenient retraction of the pedal 606. The setting of the moving port is conducive to the displacement of the movable shaft 604, which is conducive to the stable use of the overall structure.

[0034] It can be seen that both connecting plates 4 are provided with sliding openings that are compatible with the running trajectory of the movable shaft 604. The movable shaft 604 is slidingly connected to the connecting plate 4 through the sliding openings. An extension plate 605 located on the back of the connecting plate 2 is fixed to the left side of the rotating shell 602, and a pedal 606 is fixed to the bottom of the extension plate 605.

[0035] In this embodiment, the setting of the sliding opening is conducive to positioning and limiting the movable shaft 604, thereby facilitating the stability of the movable shaft 604, thereby facilitating the improvement of the stability of the pedal 606, and facilitating the stable use of the entire bed ladder.

[0036] The working principle of the above embodiment is:

[0037] When the user uses the bed ladder from the bed, he steps on the driving plate 3, and the sliding action of the movable block 501 drives the action plate 504 to move downward, thereby pushing the movable shaft 604 to move, so that the movable shaft 604 is released from the sliding opening, thereby driving the movable shaft 604 to move through the gravity action of the entire action component 6, so that the movable shaft 604 is moved to the bottom of the sliding opening, and the rotation action of the rotating shaft 601 drives the extension plate 605 to rotate, thereby realizing the extension of the pedal 606. Then the user can step on the pedal 606 and fall to the ground. If the pedal 606 needs to be retracted, the user can kick the pedal 606 with his foot. At the same time, the pulling action of the return spring 603 drives the rotating shell 602 to rotate, so that the movable shaft 604 is again stuck in the sliding opening for positioning, thereby realizing the recovery of the pedal 606. The entire bed ladder can be extended and retracted quickly, and it is convenient to use.
