Detailed Description

The clamping method comprises the following steps:

1. as shown in fig. 1 and 2, a fixed steel sheet 2 is connected to the bottom of a rain-proof cap 1, a stabilizing member connecting hole 4-a bolt fixing hole is formed in the fixed steel sheet 2, a stabilizing member is a bolt 5 which radially penetrates through a guardrail upright post, the fixed steel sheet 2 is located inside the guardrail upright post, the bolt 5 is fixedly connected with the guardrail upright post, the bolt 5 penetrates through the bolt fixing hole, and the fixed steel sheet is limited, so that the rain-proof cap 1 is stable and does not loosen. The bottom of the rain cap 1 is connected with two symmetrical fixing clamping pieces 3, and the fixing clamping pieces 3 are provided with arcs or corners. Attention is paid to when rain-proof cap welding fixation card, and two fixed cards will be equal apart from the fixed steel sheet distance, and fixed card middle part is crooked and produces arc or turning. The length of the connecting line at the outermost side of the arc or the corner is slightly larger than the inner diameter of the pipe orifice of the upright post, and the fixing clamping piece is forcibly pressed down to force the fixing clamping piece to contact with the inner wall of the upright post by virtue of the elasticity of the fixing clamping piece to generate certain deformation for clamping.

2. When in installation, the fixing clamping piece is extruded and then placed into the upright post pipe, so that the fixing clamping piece is stressed outwards and clamped with the pipe wall. If not, take out the rain hat, bare-handed will fix the card and break off with the fingers and thumb outward and draw the back and put into intraductal again, make the rain hat not rock from side to side.

3. And the bolt penetrates into the hole of the guardrail upright post firstly, then penetrates through the bolt fixing hole, penetrates out from the hole of the guardrail upright post on the other side, and screws up the nut.

(II) pulling and fixing method

1. As shown in fig. 3 and 4, a fixed steel sheet 2 is connected to the bottom of the rain cap 1, a stabilizing member connecting hole 4, namely an iron wire fixing hole, is arranged on the fixed steel sheet 2, the stabilizing member is a bolt 5 radially penetrating through the guardrail upright post, the fixed steel sheet 2 is located inside the guardrail upright post, the bolt 5 is fixedly connected with the guardrail upright post, the bolt 5 is connected with the fixed steel sheet 2 through a connecting member, and the fixed steel sheet is limited, so that the rain cap 1 is stable and does not loosen. Bolt 5 is equipped with down iron wire fixed orifices 6, and iron wire 7 connects the iron wire fixed orifices from top to bottom respectively, and bolt 5 rotates and makes partly iron wire 7 around connect on the bolt and taut fixed steel sheet 2, and the bolt is fastened again to the nut. Cutting a fixed steel sheet with the length of 15-25cm, drilling an iron wire fixing hole on the fixed steel sheet, wherein the diameter of the iron wire fixing hole is 7.5mm, and a round hole or other holes with any shapes can be formed as long as the iron wire can penetrate through and be screwed down. The length of the iron wire is 40cm, and the specification is 12 # iron wire.

2. The installation and use process is as follows: firstly, the bolt 5 is penetrated on the guardrail upright post, the nut is not screwed down temporarily, the lower iron wire fixing hole 6 is in a vertical state, one end of the iron wire is inserted into the lower iron wire fixing hole 6, after the iron wire penetrates a section of length, turning a half-turn bolt 5 to enable the penetrated iron wire to be flat or upwarp, facilitating the clamping of a clamp, clamping one end of the upwarp with the clamp, pulling upwards (the iron wire has softness and can be bent), pulling two ends of the iron wire to be aligned, enabling the rain-proof cap 1 and the upright post to be still in a separation state, binding the two ends of the iron wire after penetrating through the iron wire fixing hole of the fixed steel sheet 2, buckling the rain-proof cap 1 at the top opening of the upright post of the guardrail (the iron wire at the inner side is in a random bending state), rotating the bolt 5, the wire connected to the bolt is driven around the bolt 5 until the wire is tightened (taking care not to exert too much force to prevent the wire from breaking) and finally the nut is tightened. The rain cap 1 is in a stable state by the traction of the iron wires.
