Description

Pipe fixing fixture structure

This creation is related to a fixture structure, especially a pipe fixing fixture structure.

Press, when the vehicle or platform wants to fix the cargo, it is often necessary to install a clamp on the pipe, and use the clamp to cooperate with the hand puller to pull the rope to tighten the cargo.

The conventional clamp structure used for clamping and fixing on a pipe is rotatably connected to one end of two clamping members by two connecting members, the two clamping members are formed with opposite semicircular clamping grooves, and the two clamping members The other end is respectively provided with a rotatable association structure member and a groove for embedding the association structure member, the association structure member is provided with a screw rod and a butterfly nut screwed on the screw rod, and the clamp is embedded in the association structure member After fixing the groove of the fixing member, the butterfly nut is screwed to clamp and fix the pipe.

However, the conventional clamp structure uses the relative semi-circular clamping grooves of the two clamping members to clamp and fix the pipe fittings. Therefore, it is only suitable for round pipes with specific diameters, and has little applicability, such as pipe fittings. If the shape and size cannot be matched, the effect of clamping and fixing must be greatly reduced, and the situation of rotation and loosening is easy to occur, and the practicality is not good, so it is necessary to improve it.

In view of the above-mentioned shortcomings of the conventional fixture structure, the present inventor finally came up with the present invention based on the idea of thinking and creation, after many discussions, trial sample tests, and many modifications and improvements.
