[0019] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings. Embodiment 1:

[0020] See also Figure 1-5 A structure for improving protection efficiency includes a horizontal bar 10 and a vertical bar 20. The horizontal bar 10 is provided with a plurality of mounting holes 11. The end of the vertical bar 20 is inserted into the mounting hole 11. A limiting member 12 is provided on at least one side wall of the mounting hole 11. A limiting hole 21 is provided on the vertical bar 20 at a position corresponding to the limiting member 12. When the end of the vertical bar 20 is inserted into the mounting hole 11, the limiting member 12 is elastically deformed and extends into the limiting hole 21. By providing the limiting member 12 on the side wall of the mounting hole 11 of the horizontal bar 10, the horizontal bar 10 is a thin-walled metal pipe, so that the limiting member 12 has a certain elasticity. When the vertical bar 20 is inserted into the mounting hole 11, the limiting member 12 is deformed. When the limiting hole 21 on the vertical bar 20 is aligned with the limiting member 12, see Figure 2 The limiting member 12 elastically extends into the limiting hole 21, so that the limiting member 12 hooks the vertical rail 20, thereby improving the protective efficiency of the protective device.

[0021] The horizontal rail 10 described in the present application is the horizontal beam in CN 203821731U, and the vertical rail 20 is the grid column in CN 203821731U.

[0022] Preferably, the stopper 12 is a triangular or rectangular structure. Figure 1 , the limiting member 12 is a triangle.

The escape groove 22 is provided to prevent the limiting member 12 from being severely deformed and unable to rebound when the vertical bar 20 is inserted. During production, the escape groove 22 is formed by a stamping die.

[0025] Specifically, there are two horizontal bars 10 or an integer multiple of 2, and two ends of the plurality of vertical bars 20 are respectively inserted into the upper and lower horizontal bars 10 .

[0026] For further information, see Figure 1 , 4 The limiting member 12 is inclined to the side opposite to the mounting hole 11. The limiting member 12 is bent and tilted in advance to facilitate the insertion of the vertical rail 20. Embodiment 2:

The stopper 12 extends out of the through hole 31, and the end of the vertical rail 20 is inserted and installed in the sealing ring 30. By providing the sealing ring 30, the joint between the horizontal rail 10 and the vertical rail 20 is sealed, which plays a role in reducing vibration, preventing abnormal noise, and preventing water from entering the gap.
