Self-closing and rebounding features are key design considerations for industrial platform safety doors. Low cost, ease of installation, and ease of maintenance are also key market-driven economic indicators. Utility Model Content

[0003] The purpose of the utility model is to provide an industrial quick-installation rebound self-closing platform safety door, so as to achieve the design purpose of the platform safety door being low in cost, easy to install, and capable of rebounding and closing safely.

[0004] An industrial quick-install rebound self-closing platform safety door comprises a platform, a platform railing, a safety door, a rebound assembly and a door closing baffle; the platform railing is fixed on the platform; one end of the safety door is connected to the platform railing through the rebound assembly, and the other end is connected to the platform railing through the door closing baffle; the rebound assembly comprises an elastic steel plate, a bushing, a pin and a fastener; the bushing and the pin are respectively connected to the platform railing and the safety door; the bushing and the pin are both provided with square limiting holes. During installation, first insert the pin into the bushing, and then bend the elastic steel plate and insert it into the square limiting holes of the bushing and the pin respectively.

[0005] Furthermore, the door closing baffle is in an arc shape.

[0006] Furthermore, the rebound assembly and the door closing baffle are both connected by bolts.

[0007] The beneficial effects of the present invention are:

[0008] This utility model effectively connects the safety door to the platform railing, ensuring safe rebound closure, by utilizing a springback assembly composed of an elastic steel plate, a bushing, and a pin, and adding an arc-shaped door-closing baffle to the end of the safety door. Both the springback assembly and the door-closing baffle are connected using fasteners, facilitating quick installation of the platform safety door and easy replacement of wearing parts, while also reducing maintenance and repair costs.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-2 As shown, the industrial quick-installation rebound self-closing platform safety door includes a platform 1, a platform railing 2, a safety door 3, a rebound component 4 and a door closing baffle 5; the platform railing 2 is fixed to the platform 1; one end of the safety door 3 is connected to the platform railing 2 through the rebound component 4, and the other end is connected to the platform railing 2 through the door closing baffle 5;

[0021] The elastic component 4 includes an elastic steel plate 6, a sleeve 7, a pin 8 and a fastener 9; the sleeve 7 and the pin 8 are respectively connected to the platform railing column 2 and the safety door 3; the sleeve 7 and the pin 8 are both provided with square limit holes. During installation, the pin 8 is first inserted into the sleeve 7, and then the elastic steel plate 6 is bent and inserted into the square limit holes of the sleeve 7 and the pin 8 respectively; a flexible connection between the sleeve 7 and the pin 8 is realized; on the one hand, this limits the relative movement of the safety door 3 in the vertical direction, and on the other hand, since the turning radius of the thin elastic steel plate is larger than the turning radius of the pin, the horizontal rotation of the safety door 3 within the allowable rebound range of the elastic steel plate is guaranteed. In addition, the spring-like properties of the elastic steel plate itself enable the pin to automatically rebound to its initial state after the pushing and turning external force is removed, thereby realizing the rebound self-closing function within the safety range of the platform safety door.

[0022] Among them, the door closing baffle 5 is in an arc shape, which further limits the safe rotation space of the safety door 3 and prevents the platform door from rotating out of the platform edge under the inertia of external force.

[0023] Among them, the rebound component 4 and the door closing baffle 5 are both connected by bolts, which is not only conducive to the rapid installation of the platform door and easy replacement of various components, but also conducive to effectively reducing maintenance and repair costs in the later stage.

[0024] To sum up, the industrial quick-install rebound self-closing platform safety door utilizes the rotating fit of the shaft sleeve and the pin shaft, the flexible connection of the spring-like steel plate and the installation of an arc-shaped closing baffle at the end of the platform door to meet the industrial demand for the safe rebound of the platform safety door within the allowable range; the rebound component and the closing baffle are both connected by bolts, which is not only conducive to the rapid installation of the platform safety door and the easy replacement of wearing parts, but also the rebound component and the closing baffle can be made into standard parts, achieving the economic goal of simple later maintenance, time saving, labor saving and low cost.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
