[0015] The following will be described in detail with reference to the embodiments of the present utility model and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:
[0017] As Figure 1 shown, a telescopic elevator car top guardrail includes a fixing frame 1, a telescopic frame 2, a locking device 3 and a safety guardrail 4. The fixing frame 1 is installed on the fixed part of the elevator car top. The fixing frame 1 includes a side fixing frame 11 and a rear fixing frame 12. The side fixing frame 11 and the rear fixing frame 12 are tightly connected by bolts 31. The telescopic frame 2 is slidably sleeved in the side fixing frame 11 and the rear fixing frame 12. The telescopic frame 2 is fastened to the tops of the side fixing frame 11 and the rear fixing frame 12 by the locking device 3. The safety guardrail 4 is fixed to the top of the telescopic frame 2.
[0018] The side fixing frame 11 includes a front side guardrail 111 and a rear side guardrail 112. Both the front side guardrail 111 and the rear side guardrail 112 are composed of four fixed square tubes. The four fixed square tubes include three fixed square tubes fixed in a "ㄩ" shape and one fixed square tube fixed in the middle part of the "ㄩ" shaped structure.
[0019] The rear fixing frame 12 is composed of five fixed square tubes. The five fixed square tubes include a bottom horizontal square tube at the bottom, three vertical square tubes respectively fixed at the left end, middle and right end of the bottom horizontal square tube, and a middle horizontal square tube fixed in the middle part of the vertical square tubes.
[0020] The described locking device 3 includes a bolt 31 or a pin. The locking device 3 is used to fix the position of the telescopic frame 2 to ensure that the safety guardrail 4 can remain stable after being extended to the required length.
[0021] The safety guardrail 4 connected to the side fixing frame 11 through the telescopic frame 2 and the safety guardrail 4 connected to the rear fixing frame 12 through the telescopic frame 2 are interconnected by bolts 31.
[0022] Locking holes are provided in the vertical square tubes of the front side guardrail 111, the rear side guardrail 112 and the rear fixing frame 12. The front side guardrail 111, the rear side guardrail 112 and the rear fixing frame 12 are tightened against the telescopic frame 2 by bolts 31 passing through the locking holes.
[0023] A guardrail warning sign 5 is connected to the safety guardrail 4 above the rear fixing frame 12. The safety guardrail 4 is used to provide a physical barrier to prevent people from accidentally falling.
[0024] During application, when the top space needs to be used, the telescopic frame 2 can be retracted into the fixing frame 1 by loosening the locking device 3, thereby reducing the height of the guardrail. When the top space does not need to be used, the telescopic frame 2 can be stretched and fixed at a predetermined position by using the locking device 3, so as to provide sufficient safety protection and ensure that the safety guardrail 4 can be stably and safely maintained at the set position in any state.
