fig. 2 is a sectional view of the internal structure of the spiral pipe on the spiral corrugated pipe with strong compression resistance.
Detailed Description
Referring to fig. 1-2, the spiral corrugated pipe with high compression resistance provided by the utility model comprises a main pipe 1 and a spiral pipe 2, wherein the spiral pipe 2 is spirally wound on the main pipe 1 along the length direction of the main pipe 1, a cavity 21 arranged along the trend of the spiral pipe 2 is formed in the spiral pipe 2, a supporting piece 3 for supporting the inner side wall of the spiral pipe 2 is arranged in the cavity 21, and a reinforcing plate 4 is fixed at the bottom end of the supporting piece 3.
The support 3 supports the inner side wall of the spiral pipe 2, and ring rigidity of the pipe fitting is enhanced.
However, in the above embodiment, the external force acts on the spiral pipe 2 and then acts on the main body pipe 1 again through the reinforcing plate 4, in order to better protect the main body pipe 1, the reinforcing plate 4 is made of an elastic steel plate, two ends of the reinforcing plate 4 are abutted against the inner bottom wall of the spiral pipe 2, a buffer space is formed between the bottom wall of the reinforcing plate 4 and the inner bottom wall of the spiral pipe 2, when the reinforcing plate 4 is subjected to downward acting force, the reinforcing plate 4 deforms, the work generated by the external force is converted into elastic potential energy of the reinforcing plate 4 and stored in the reinforcing plate 4, and the reinforcing plate 4 is arranged to have a certain buffer effect when the pipe is subjected to the external force.
The support member 3 comprises a first support part 31 for forming support on the inner top wall of the spiral tube 2 and a second support part 32 for forming support on the two inner side walls of the spiral tube 2, and the support direction is additionally arranged, so that the support effect is improved.
When the spiral tube 2 is acted by external force, the supporting piece 3 can apply a reverse acting force to the inner wall of the spiral tube 2 besides supporting the spiral tube 2, if the contact area between the spiral tube 2 and the supporting piece 3 is too small, the pressed strength of the spiral tube 2 is increased, the inner wall of the spiral tube 2 with excessive pressure is easily damaged, and in order to reduce the pressed strength of the inner wall of the spiral tube 2 under the action of the external force with the same size, the first supporting part 31 is provided with a first bonding surface which can be bonded with the inner top wall of the spiral tube 2; the second support portion 32 has a second contact surface capable of contacting the inner side wall of the spiral pipe 2.
Because reinforcing plate 4 adopts the elastic steel plate material, when the tubular product damages, need retrieve reinforcing plate 4, support piece 3, for the convenience with support piece 3, reinforcing plate 4 and spiral pipe 2 separation, support piece 3 and reinforcing plate 4 all cup joint in cavity 21 along spiral pipe 2 trend, during the recovery directly with support piece 3 and reinforcing plate 4 follow in spiral pipe 2 take out can.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
