[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figures 1-4 As shown, this utility model provides an elevator stair surface anti-collision mechanism, including a stair surface 1. A protective component is provided on one side of the stair surface 1. The protective component is limited by a card seat. Two sets of limiting blocks 2 are rotatably connected to the upper and lower ends of the card seat. One end of the limiting block 2 is used to insert the protective component and cooperate with the card seat to lock the protective component. The other end is connected to the locking component to lock itself.

[0022] First, install the mounting bracket on one side of the elevator surface 1. Place the protective component in the corresponding position on the bracket. Then, rotate the limiting block 2 so that one end of the limiting block 2 inserts into the protective component. After insertion, the limiting block 2, together with the mounting bracket, initially limits the movement of the protective component. Next, the locking component connects to the other end of the limiting block 2, locking it in its current position. This prevents the limiting block 2 from rotating freely, thus firmly locking the protective component to one side of the elevator surface 1, completing the installation process. During normal elevator use, when an object impacts the elevator surface 1, the protective component is the first to absorb the impact force, providing effective protection for the elevator surface 1. When it is necessary to remove the protective component, first operate the locking component to release the locking of the limiting block 2. After releasing the lock, rotate the limiting block 2 to disengage it from the protective component, allowing the protective component to be removed from the mounting bracket, completing the disassembly process.

[0023] Compared with the traditional method of fixing the protective piece by using glue or a large number of screws, the installation time and operation steps are greatly reduced. When disassembling, the locking assembly is first unlocked from the limiting block 2, then the limiting block 2 is rotated to make it disengage from the protective piece, and then the protective piece can be easily removed. This disassembly method avoids problems that may be encountered in the traditional method, such as difficulty in separating due to glue adhesion and difficulty in rotating due to rusted screws, thereby improving disassembly efficiency. When the protective piece needs to be replaced due to damage caused by impact or the like, the quick installation and disassembly process enables the new protective piece to quickly replace the old protective piece, which means that the time for the elevator to be temporarily suspended due to replacement of the protective piece is greatly reduced, thereby greatly reducing the impact on the normal operation of the elevator and improving the transportation efficiency of personnel and goods in the building.

[0024] Specifically, the locking assembly includes a limiting seat 3, a spring 4, a lock tongue 5, and a first positioning hole 6. The upper and lower ends of the clamping seat are provided with the limiting seat 3 corresponding to the limiting block 2. The inner cavity of the limiting seat 3 is provided with the spring 4. One end of the spring 4 is connected to a group of lock tongues 5. The lock tongues 5 can be inserted into the first positioning hole 6 formed at one end of the limiting block 2.

[0025] First, four groups of L-shaped clamping blocks 7 are respectively installed at the upper, lower, left, and right positions on one side of the ladder surface 1. These clamping blocks 7 collectively form a clamping seat. Since the clamping blocks 7 are L-shaped structural members, their special shape can preliminarily limit the protective piece in the area surrounded by the clamping seat. After the clamping seat is installed, the protective piece is placed in the corresponding position of the clamping seat. The limiting block 2 is rotated so that one end of the limiting block 2 is inserted into the protective piece. The spring 4 will push the lock tongue 5 by its own elastic force so that the lock tongue 5 is inserted into the first positioning hole 6 formed at one end of the limiting block 2. The limiting block 2 is locked at the current position and cannot be rotated at will, thereby firmly locking the protective piece on one side of the ladder surface 1. Thus, the installation process is completed.

[0026] When disassembling, no complex tools or additional operation steps are required. Compared with the traditional method of fixing the protective piece by using glue, the time for waiting for the glue to dry is completely saved. Compared with the method of fixing the protective piece by using a large number of screws, there is no need to screw the screws one by one, thereby greatly improving the installation efficiency. When the protective piece needs to be replaced due to damage caused by impact or the like, the quick installation and disassembly process enables the new protective piece to quickly replace the old protective piece, which means that the time for the elevator to be temporarily suspended due to replacement of the protective piece is greatly reduced, thereby greatly reducing the impact on the normal operation of the elevator and improving the transportation efficiency of personnel and goods in the building.

[0027] Wherein: the protection piece includes protection shell 8, buffer 9 and protection plate 10, the card seat plug-in connection a set of protection shell 8, the inner cavity of protection shell 8 is bonded a set of buffer 9, the other side of buffer 9 is bonded a set of protection plate 10, protection plate 10 can slide along the inner cavity of protection shell 8, the upper and lower ends of protection shell 8 are provided with second positioning hole 11 corresponding to limiting block 2.

[0028] The protection piece is installed in the corresponding position by the plug-in connection of the card seat, at this time, the protection shell 8 and the card seat are preliminarily connected, the second positioning hole 11 opened at the upper and lower ends of the protection shell 8 is matched with the limiting block 2, one end of the limiting block 2 is inserted into the second positioning hole 11, and the limiting block 2 is matched with the card seat to realize the locking of the protection piece, so that the protection piece is stably installed on the ladder surface 1, when the ladder surface 1 is impacted by external force, the protection plate 10 first bears the impact force, because the protection plate 10 can slide along the inner cavity of the protection shell 8, the buffer 9 will be deformed to absorb and disperse the impact force, thereby playing a role of buffering and anti-collision, and protecting the ladder surface 1 from being damaged.

[0029] The plug-in connection and the positioning and locking mode of the limiting block 2 matched with the card seat make the installation and dismounting process of the protection piece simple and convenient, improve the maintenance efficiency, the setting of the buffer 9 can effectively absorb and disperse the external force impact, reduce the influence of the impact force on the ladder surface 1, and the protection plate 10 can slide along the inner cavity of the protection shell 8, this design makes the protection piece better adapt to the direction change of the force when impacted, and further improves the buffering effect.

[0030] Working principle: four groups of L-shaped clamping blocks 7 are respectively installed at the upper, lower, left and right four directions of one side of the ladder surface 1, and these clamping blocks 7 jointly form a card seat, because the clamping block 7 is an L-shaped structural member, its special shape can preliminarily limit the protection piece in the area surrounded by the card seat, after the card seat is installed, the protection piece is placed in the corresponding position of the card seat, the limiting block 2 is rotated, one end of the limiting block 2 is inserted into the second positioning hole 11, and the limiting block 2 is matched with the card seat to realize the locking of the protection piece, so that the protection piece is stably installed on the ladder surface 1, the spring 4 will push the lock tongue 5 to make it inserted into the first positioning hole 6 opened at one end of the limiting block 2 by the elastic force of the spring 4, and the limiting block 2 is locked at the current position and cannot be rotated at will, so that the protection piece is firmly locked on one side of the ladder surface 1, and the installation process is completed, when the ladder surface 1 is impacted by external force, the protection plate 10 first bears the impact force, because the protection plate 10 can slide along the inner cavity of the protection shell 8, the buffer 9 will be deformed to absorb and disperse the impact force, thereby playing a role of buffering and anti-collision, and protecting the ladder surface 1 from being damaged.
