[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses an elevator car top protection device, referring to Figure 1 and Figure 2, including a box top plate 1, two connecting blocks 1 are fixedly installed on both sides of the box top plate 1, one side of the four connecting blocks 1 is hinged with two contraction plates 2, the tops of the two contraction plates 2 are provided with two slide grooves, the inner side walls of the four slide grooves are slidably connected with sliding rods 1 3, the tops of the four sliding rods 1 3 are fixedly installed with two cross bars 4, both ends of the two cross bars 4 are hinged with rotating blocks 5, one side of the four rotating blocks 5 is fixedly installed with a telescopic rod 1 6, the outer sides of the four telescopic rods 1 6 are bolted with connecting sleeves 7, by rotating the contraction plate 2, and then pulling the cross bar 4, the sliding rod 1 3 is driven to slide out along the inner side wall of the slide groove, and then the telescopic rod 3 10 is rotated to abut against the top of the contraction plate 2, the rotating block 5 is rotated, and then one end of the telescopic rod 1 6 is pulled, so as to play the role of folding, contracting and extending.

[0021] Reference Figure 1 and Figure 2 The bottom ends of the two connecting sleeves 7 are fixedly connected with telescopic rods 28, and two connecting blocks 2 are hinged on both sides of the two telescopic rods 28. The bottom surfaces of the four connecting blocks 2 are fixedly installed with a box top plate 1. The telescopic rods 28 are rotated along the connecting blocks 2 and are perpendicular to the box top plate 1. By pulling one end of the telescopic rod 1 6 and one end of the opposite telescopic rod 1 6 into the connecting sleeve 7, the protective device structure is strengthened and folded and retracted.

[0022] Reference Figure 1 A square hole is provided in the middle of the two retractable plates 2, and a protective net 9 is threadedly installed on the inner wall of the two square holes. Two telescopic rods three 10 are hinged on one side of the two retractable plates 2. Four card slots are provided on the top of the box top plate 1, and one end of the four telescopic rods three 10 is engaged with the card slot. When the retractable plate 2 is rotated, the telescopic rod three 10 is rotated to rest on the card slot of the box top plate 1, which plays a role in strengthening the structure and achieves the effect of light folding.

[0023] Reference Figure 1 and Figure 2 The connecting sleeve 7 is located at the intersection of the two telescopic rods 8. The telescopic rods 8 are symmetrically distributed. The connecting sleeve 7 connects and fixes the telescopic rods 8, strengthens the connection toughness of the telescopic rods 8, and prevents the guardrail from accidentally slipping due to insufficient blocking strength.

[0024] Reference Figure 1 and Figure 3 The hinges of the retractable plate 2, the second telescopic rod 8 and the third telescopic rod 10 are all curved, and the curvature of the bottom surface makes it easier to rotate.

[0025] The implementation principle of the elevator car top protection device of the embodiment of the present application is as follows: first, by rotating the retractable plate 2, the telescopic rod 2 8 is rotated along the connecting block 2 and perpendicular to the box top plate 1, and by pulling one end of the telescopic rod 1 6, one end of the opposite telescopic rod 1 6 enters into the connecting sleeve 7, so as to strengthen the structure of the protection device and fold and retract, and then pull the cross bar 4 to drive the slide bar 1 3 to slide out along the inner wall of the slide groove, and then rotate the telescopic rod 3 10 to abut against the top of the retractable plate 2, rotate the rotating block 5, and then pull one end of the telescopic rod 1 6 to achieve the effects of folding, contracting and extending, and secondly, The telescopic rod 2 8 rotates along the connecting block 2 and is perpendicular to the box top plate 1. By pulling one end of the telescopic rod 1 6 and one end of the opposite telescopic rod 1 6 into the connecting sleeve 7, the protective device structure is strengthened and folded and retracted. Finally, the telescopic rod 2 8 is retracted and rotated to be parallel to the retracting plate 2, and then the cross bar 4 is pressed downward to make the slide bar 3 fall along the slide groove, and the connecting sleeve 7 is pressed downward to overlap the upper and lower parts of the telescopic rod 3 10. Then, by rotating the telescopic rod 3 10 to be parallel to the retracting plate 2, and then rotating the retracting plate 2 to be parallel to the box top plate 1, the folding effect is achieved.
