The light curtain is suspended on the second mounting portion, the fixed connection between the hall door sealing strip and the hall door is effectively solved, and the installation of the light curtain is not affected, meanwhile, there is no limitation on the exposed height after the screw is fixed, as long as it is not higher than the first mounting portion and the second mounting portion, so the ability requirement of the operator is greatly reduced.

[0019] The technical solution in the embodiment of the present application will be described clearly and completely in combination with the drawings in the embodiment of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, and is by no means any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] As Figs. 1-2The elevator car hall door seal strip shown, including the skeleton 1 is symmetrically installed on the two elevator car hall doors and cooperates with each other, the skeleton 1 includes the first installation part 11 that protrudes upwards, the second installation part 12 that is concave downwards and the third installation part 13 that protrudes upwards, the head of the second installation part 12 is connected to the first installation part 11, the tail of the second installation part 12 is connected with the third installation part 13 that protrudes upwards, and the longitudinal section shape of the skeleton 1 is M-shaped. The second installation part 12 is installed on the hall door, the light curtain 2 is suspended on the second installation part 12, the left side of the light curtain 2 is attached to the first installation part 11, and the right side of the light curtain 2 is installed on the third installation part 13. According to actual needs, the left side of the light curtain 2 can be installed on the first installation part 11, and the right side of the light curtain 2 is attached to the third installation part 13. In order to make the light curtain 2 have a more stable installation basis, the height of the third installation part 13 is set to be equal to the height of the first installation part 11, and in order to reduce the process complexity, the structure of the third installation part 13 is directly set to be a symmetric structure with the structure of the first installation part 11, so that the left and right sides of the light curtain 2 are balanced.

[0021] In order to further provide stable support for the third installation part 13, the third installation part 13 is provided with a first support 131, a connecting piece 132 and a second support 133, the head and tail of the connecting piece 132 are connected to the first support 131 and the second support 133 respectively, the first support 131 is vertically arranged on the car hall door, and the second support 133 is obliquely arranged on the car hall door. Alternatively, the first support 131 is obliquely arranged on the car hall door, and the second support is vertically arranged on the car hall door. There is no limitation, and the suitable arrangement mode of the first support 131 and the second support is selected according to actual installation convenience. In this way, the third installation part 13 can maintain its shape without deformation when subjected to stress, and also plays a sealing and anti-collision role.

[0022] In specific implementation, the longitudinal section shape of the third installation part is set to be an inverted U-shaped.

[0023] The technical effect of the embodiment is that the tail of the second installation part is connected with the third installation part that protrudes upwards, the light curtain is suspended on the second installation part, and the left and right sides of the light curtain are respectively attached to or / and installed on the first installation part and the third installation part. This arrangement increases the contact area between the light curtain and the skeleton, solves the defect of the suspension of one side of the light curtain, provides a more stable installation basis, makes the light curtain stable during the frequent opening and closing process of the elevator door, and is not easy to loosen or deform or deviate. Meanwhile, the protruding third installation part also plays a certain buffering role, reducing the impact force on the seal strip and the light curtain when the elevator door is closed. The light curtain is suspended on the second installation part, effectively solving the fixed connection between the hall door seal strip and the hall door, and not affecting the installation of the light curtain. Meanwhile, there is no limitation on the height exposed after screw fixation, as long as it is not higher than the first installation part and the second installation part, greatly reducing the ability requirement of the operator.
