Description

Technical Field

[0001] The utility model belongs to the technical field of fastening of electric power pipes, and in particular relates to a shockproof fastening device for an electric power pipe. Background Art

[0002] During the laying of power cables, in order to avoid external erosion, these power cables need to be covered with power pipes for protection. The power pipe is a product that uses PE (modified polyethylene) for hot dip plastic or epoxy resin for internal and external coating. It has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation, will not cause electrical corrosion, has low water absorption, high mechanical strength, and a small friction coefficient. It can achieve the purpose of long-term use and can effectively prevent damage to plant roots and soil environmental stress. However, in addition to being affected by plant roots and soil stress, power pipes buried underground will also be affected by road vibrations and earthquakes. Once the power pipe is dislocated or cracked by vibration, rainwater or other things that enter the power pipe will cause damage to the power cable. Utility Model Content

[0018] Description of the working method of this utility model:

[0019] The anti-vibration fastening device of the electric power pipe adopting the structure is formed by setting a plurality of sets of fastening plug plates 1 which are sequentially plugged in up and down. The upper end face and the lower end face of the fastening plug plates 1 are both provided with corresponding pipe positive semicircular grooves 11. When the fastening plug plates 1 are plugged in up and down, the corresponding pipe positive semicircular grooves 11 are enclosed to form a pipe positive groove 12. The electric power pipe is clamped by the pipe positive groove 12 to fix the electric power pipe. Therefore, when there are many electric power pipes to be laid, they can be distributed layer by layer. After the electric power pipes are laid, the upper set of fastening plug plates 1 can rely on The upper and lower fastening plates 1 are pressed together by gravity, but the fastening plates 1 formed by stacking and plugging in sequence are not enough to resist the vibration force. Therefore, a buckle hole 13 and a plugging hole 14 are provided on the upper end surface of the fastening plates 1, and a plug hook 15 and a plugging column 16 are provided on the lower end surface of the fastening plates 1. When the upper and lower fastening plates 1 are plugged in, the plug hook 15 can be inserted into the buckle hole 13, and the plugging column 16 can be inserted into the plugging hole 14. However, the stabilizing effect formed by this plugging form alone is not very good. The buckling groove 21 is provided to achieve a better stabilizing effect. The buckling hole 13 and the plug hole 14 are connected to the buckling groove 21 respectively. The rotating column 211 provided in the buckling groove 21 is used to connect the middle part of the buckling crank rod 22, so that the buckling crank rod 22 can rotate with the rotating column 211 as the rotation center. A buckling portion 221 is provided at one end of the buckling crank rod 22. When the upper group fastening plug plate 1 is plugged into the lower group fastening plug plate 1, the plug column 16 enters the plug hole 14 and abuts against the buckling. On the other end of the bent rod 22, continuous downward pressure will act on the other end of the buckling bent rod 22, causing the buckling bent rod 22 to rotate with the rotating column 211 as the rotation center, and the buckling portion 221 moves upward. During the upward movement of the buckling portion 221, the plug hook 15 also continues to move downward, and finally the buckling portion 221 is buckled on the plug hook 15, and finally the two sets of fastening plug plates 1 are fixed to each other, especially after the upper set of fastening plug plates 1 is subjected to the pressure of the power pipe, the connection between the two sets of fastening plug plates 1 will be tightened.

[0020] If the upper and lower sets of fastening plug plates 1 are connected face to face when plugged in, the tangential force of the plane will easily cause damage to the plug hook 15 and the plug-in column 16 on the tangent surface. Therefore, a limit groove 17 is provided on the upper end surface of the fastening plug plate 1, and a limit column 18 is provided on the lower end surface of the fastening plug plate 1. When the upper and lower sets of fastening plug plates 1 are plugged in, the limit groove 17 and the limit column 18 cooperate to achieve a better stabilization effect.

[0021] Since the connection between the upper and lower groups of fastening plug plates 1 is achieved by the continuous downward pressure of the upper group of fastening plug plates 1, the position fixing of the buckling crank rod 22 has a great influence on the stability of the connection. Therefore, the buckling crank rod 22 can be fixed in its buckling position after the buckling is completed, which can avoid the loosening between the two groups of fastening plug plates 1. Therefore, a fixing plate 3 is added, and a fixing hole 31 and four groups of fixing columns 32 are provided on the fixing plate 3. A connecting hole 233 that cooperates with the fixing column 32 is opened on the cover plate 23. When the fixing column 32 is engaged in the connecting hole 233, the fixing column 32 will enter the buckling groove 21 and limit the upper and lower end faces of the buckling crank rod 22, and the fixing hole 31 on the fixing plate 3 is matched with the threaded hole 214 on the rotating column 211. The fixing plate 3 can be fixed to the cover plate 23 by screwing a screw into the threaded hole 214. Under this structure, the buckling crank can be fixed to avoid the upper and lower groups of fastening plug plates 1 from being disengaged after connection.

[0022] The beneficial effect of the utility model is that: the initial fixing effect is achieved by inserting the plug hook 15 and the plug post 16 on the upper group of fastening plug plates 1 into the buckling hole 13 and the plug hole 14 on the lower group of fastening plug plates 1, and the buckling groove 21 provided in the fastening plug plate 1 is rotated by the abutment of the plug post 16 through the buckling bent rod 22 provided therein, and the buckling part 221 on the buckling bent rod 22 is buckled on the plug hook 15, so as to achieve the second fixing effect. After the upper group of fastening plug plates 1 are subjected to the pressure of the power pipe, the connection between the two groups of fastening plug plates 1 will be tightened, and the plug hook 15 and the plug post 16 of the lowest layer of fastening plug plates 1 can be directly inserted into the ground for fixing, and the third fixing effect can also be achieved through the cooperation of the limiting groove 17 and the limiting post 18, so that a better fastening effect can be achieved during the laying process of the power pipe.
