Detailed Description
In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model provides a warning fence for elevator maintenance, which comprises at least two rectangular frames as shown in figures 1-4, wherein in the embodiment, the number of the rectangular frames is three, and a cloth block with warning symbols or warning words can be arranged in each rectangular frame. The three rectangular frames are respectively a middle rectangular frame 1 in the middle and side rectangular frames 2 positioned at two ends of the middle rectangular frame 1, a welding positioning plate 3 is arranged at the upper end of each side rectangular frame 2, a through hole is arranged in the middle of each positioning plate 3, and the through holes penetrate through the vertical parts of two sides of the middle rectangular frame 1. The lower ends of the side rectangular frames 2 and the middle rectangular frame 1 are connected through hinges 6.
The side of the positioning plate 3 is provided with a plurality of positioning slots 31 which are distributed at equal intervals. The two ends of the upper beam of the middle rectangular frame 1 are sleeved with the sliding sleeves 4 which can slide, the sliding sleeves 4 are provided with the positioning blocks 42 matched with the positioning grooves 31, and the positioning blocks 42 can be inserted into any one of the positioning grooves 31, so that the locking of the relative angle between the middle rectangular frame 1 and the side rectangular frame 2 can be realized.
The other end of the sliding sleeve 4 is provided with a spring 5, the spring 5 props against the sliding sleeve 4, a stop ring 11 is arranged on an upper cross beam of the middle rectangular frame 1, and the stop ring 11 is used for limiting the end part of the spring 5, so that the spring 5 firmly props against the sliding sleeve 4, and the positioning block 42 is inserted into the positioning groove 31. In order to prevent the sliding sleeve 4 from rotating, a long hole 41 (through hole) is formed in the outer side wall of the sliding sleeve 4, the positioning pin 12 is arranged in the long hole 41, the positioning pin 12 is fixed on the cross beam, and the middle rectangular frame 1 prevents the sliding sleeve 4 from rotating by itself through the positioning pin 12.
