The blind screw hole of screw rod II with blind screw hole and collision mat, screw rod II is matched with the external screw thread of screw rod I, two screw rods II
Spinning is at the both ends of screw rod I, which is characterized in that the thickness of length≤wall of screw rod I, collision mat are sleeved on the centre of screw rod I
In light bar segment.
Further preferably technical solution is the utility model, and the outer diameter of the blind screw hole section of screw rod II is more than external screw thread
The diameter of section and intermediate light bar segment.
Further preferably technical solution is the utility model, is equipped with conducive to spanner bayonet clamping at the middle part of screw rod I
Flat part I.
Further preferably technical solution is the utility model, is equipped with conducive to spanner bayonet clamping at the middle part of screw rod II
Flat part II.
Further preferably technical solution is the utility model, has evagination in the end of the blind screw hole section of screw rod II
Edge is set with conical plastics set in the blind screw hole section of screw rod II, has seam allowance in the small head end of conical plastics set, seam allowance
The diameter matches of diameter and outward flange.
Further preferably technical solution is the utility model, and screw rod II is chromium plating screw rod.Screw rod II is reusable, plating
Chromium is for antirust.
The special assembly and disassembly sleeve of three-stage environmental protection water-proof bolt, including sleeve body, there is U-shaped long gap, U in sleeve body
The opening of the long gap of type has U-shaped mouth plug in one end of sleeve body on the end inner wall of sleeve body, U-shaped mouth plug
Width is suitable with the thickness of flat part I at I middle part of screw rod, there is square hole plug, square hole on the inner wall of the other end of sleeve body
The square hole size of plug is matched with the square toes size of electric wrench.Hole is extended radially through in sleeve body.
Compared with prior art, since the utility model waits for directly unloading screw rod II down after wall pours,
Not only time saving and energy saving, work efficiency is high, and is not in the phenomenon that gas cutting screw rod is by wall sooting, belongs to environmentally friendly production
Product.

Specific implementation mode
As shown, three-stage environmental protection water-proof bolt, including a both ends carry I 3, two one end bands of externally threaded screw rod
Screw rod II 1 and collision mat 4 of the external screw thread one end with blind screw hole, the external screw thread of the blind screw hole and screw rod I 3 of screw rod II 1
Matching, two II 1 spinnings of screw rod are sleeved on screw rod in the both ends of screw rod I 3, the thickness of length≤wall of screw rod I 3, collision mat 4
In I 3 intermediate light bar segment.
The outer diameter of the blind screw hole section 1-4 of screw rod II 1 is more than the diameter of external thread section 1-1 and intermediate light bar segment 1-3.
It is equipped with I 3-1 of flat part conducive to spanner bayonet clamping at the middle part of screw rod I 3.
It is equipped with II 1-2 of flat part conducive to spanner bayonet clamping at the middle part of screw rod II 1.
There is outward flange 1-5 in the end of the blind screw hole section 1-4 of screw rod II 1, in the blind screw hole section 1- of screw rod II 1
