There are multiple vertical guardrails 1, and the multiple vertical guardrails 1 are used to be connected to the car roof. A horizontal guardrail 2 is connected between two adjacent vertical guardrails 1 arranged horizontally, and a longitudinal guardrail 3 is connected between two adjacent vertical guardrails 1 arranged vertically.

[0030] The vertical guardrail 1 includes a vertical guardrail body 11 and a vertical guardrail body 2 12 connected to the vertical guardrail body 11 and formed by bending;

[0031] The vertical guardrail body 11 is provided with a notch 13 formed by stamping, the upper edge of the notch 13 is connected to an upper clamping portion 14 formed by bending, and the lower edge of the notch 13 is connected to a lower clamping portion 15 formed by bending. The upper clamping portion 14, the lower clamping portion 15 and the vertical guardrail body 11 form a horizontal guardrail bayonet, which is used to clamp the horizontal guardrail 2. The vertical guardrail body 2 is provided with a notch 16 formed by stamping, the upper edge of the notch 16 is connected to an upper clamping portion 17 formed by bending, and the lower edge of the notch 16 is connected to a lower clamping portion 18 formed by bending. The upper clamping portion 17, the lower clamping portion 18 and the vertical guardrail body 2 form a longitudinal guardrail bayonet, which is used to clamp the longitudinal guardrail 3.

[0032] The bottom of the vertical guardrail 1 is connected with a clamping portion 19 formed by bending, and preferably, the bottoms of the vertical guardrail body 11 and the second vertical guardrail body 12 are both connected with the clamping portion 19, and the clamping portion 19 is connected to a clamping hole preset on the car roof.

[0033] The above-mentioned guardrail assembly only involves guardrail components including vertical guardrail 1, horizontal guardrail 2, and longitudinal guardrail 3, and does not involve any fasteners. It can be seen that the guardrail assembly involves a small number and type of parts, and is more convenient to install; in the above-mentioned guardrail assembly, the guardrail components are directly connected by a snap-in method, and the vertical guardrail 1 and the car roof are also directly connected by a snap-in method, which is convenient to connect; the above-mentioned guardrail assembly is made of sheet metal as raw material, so that the elevator factory can make full use of the sheet metal waste left over from shearing or stamping, thereby improving the elevator factory's utilization rate of sheet metal waste; the above-mentioned guardrail assembly is made of sheet metal as raw material. During manufacturing, a shearing machine is used to cut the waste to suitable specifications, a punching machine is used to punch out notches including notch 13 and notch 2 16, and a bending machine is used to bend the sheet metal into shape. In short, the necessary equipment such as shearing machines, punching machines, bending machines, etc. commonly used by elevator factories and the technicians of these equipment are directly utilized, without the need for other equipment and personnel investment, and the cost can be controlled.

[0034] When assembling the guardrail assembly, first, the vertical guardrail 1 is clamped onto the car roof via the clamping portion 19, then the transverse guardrail 2 is clamped into the transverse guardrail clamping port, and the longitudinal guardrail 3 is clamped into the longitudinal guardrail clamping port. When clamping the transverse guardrail 2, first, the lower end of the transverse guardrail 2 is inserted into the transverse guardrail clamping port, then, the upper clamping portion 14 is opened upwards, and after the upper portion of the transverse guardrail 2 is inserted into the transverse guardrail clamping port, the upper clamping portion 14 is released, and the upper clamping portion 14 is reset. When clamping the longitudinal guardrail 3, first, the lower end of the longitudinal guardrail 3 is inserted into the longitudinal guardrail clamping port, then, the upper clamping portion 2 17 is opened upwards, and after the upper portion of the longitudinal guardrail 3 is inserted into the longitudinal guardrail clamping port, the upper clamping portion 2 17 is released, and the upper clamping portion 2 17 is reset.

[0035] The upper clamping part 14 and the lower clamping part 15 are located in the angle formed by the vertical guardrail body 11 and the vertical guardrail body 2 12, or in other words, are located on the inner wall surface of the vertical guardrail body 11, and the vertical guardrail body 11 prevents the horizontal guardrail 2 from escaping outward from the horizontal guardrail clamping mouth. Moreover, on this basis, the upper clamping part 2 17 and the lower clamping part 2 18 are located on the outer wall surface of the vertical guardrail body 2 12, or in other words, are located outside the angle formed by the vertical guardrail body 11 and the vertical guardrail body 2 12, and the horizontal guardrail 2 and the vertical guardrail 3 will not interfere with each other when they are clamped.

[0036] In this embodiment, the horizontal guardrail 2 is further improved. The horizontal guardrail 2 includes a horizontal guardrail body 21 and a limiting portion 22 connected to the horizontal guardrail body 21 and formed by bending. The limiting portion 22 limits the horizontal guardrail 2 in the horizontal guardrail bayonet to prevent the horizontal guardrail 2 from moving laterally, thereby preventing the horizontal guardrail 2 from slipping out of the horizontal guardrail bayonet. In this embodiment, the limiting portion 22 is arranged between two adjacent vertical guardrails 1, and the limiting portion 22 becomes an anti-cutting portion that can prevent hands from being cut. In order to achieve the anti-cutting effect, the limiting portion 22 includes a horizontal portion 221 connected to the horizontal guardrail body 21, and a lower bent portion 222 connected to the horizontal portion 221 and formed by bending downward. The downward length of the lower bent portion 222 should be as large as possible. In this way, when the operator grabs the limiting portion 22, he will not grab the edge of the lower bent portion 222 and will not be cut by the edge.

[0037] Similarly, the longitudinal guardrail 3 includes a longitudinal guardrail body 31, and a limiting portion 2 32 connected to the longitudinal guardrail body 31 and formed by bending. The limiting portion 2 32 can limit the longitudinal guardrail 3 in the longitudinal guardrail bayonet to prevent the longitudinal guardrail 3 from moving longitudinally, thereby preventing the longitudinal guardrail 3 from slipping out of the longitudinal guardrail bayonet. In this embodiment, the limiting portion 2 32 is arranged between two adjacent vertical guardrails 1, and the limiting portion 2 32 becomes an anti-cutting portion that can prevent hands from being cut. In order to achieve the anti-cutting effect, the limiting portion 2 32 includes a horizontal portion 2 321 connected to the longitudinal guardrail body 31, and a lower bending portion 2 322 connected to the horizontal portion 2 321 and formed by bending downward. The downward length of the lower bending portion 2 322 should be as large as possible. In this way, when the operator grabs the limiting portion 2 32, he will not grab the edge of the lower bending portion 2 322 and will not be cut by the edge.
