Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the invention provides a self-positioning structure of an air filter vulcanized rubber pipeline clamp, which comprises a hose 1 and a clamp 2, wherein an annular positioning groove 3 is formed at the end of the hose 1, a positioning column 31 is arranged on the annular positioning groove 3, the diameter of the outer end of the positioning column 31 is larger than that of a rod part, the clamp 2 comprises a clamping band 21 and an end screw part 22, the clamping band 21 is provided with a positioning long hole 23 along the circumferential direction close to the end screw part 22, the width of the positioning long hole 23 is smaller than that of the outer end of the positioning column 31, the width of the rod part of the positioning column 31 is matched with that of the positioning long hole 23, an clamping end 24 is arranged at the end of the positioning long hole 23, the inner diameter of the clamping end 24 is larger than that of the outer end of the positioning column 31, a limiting block 32 is arranged on the annular positioning groove 3, and the end screw part 22 is in a limiting state in the circumferential direction after being clamped into the limiting block 32, tightening the screw tightening clamp band 21 on the end screw part 22 fixedly connects the hose 1 to the hard pipe.

Preferably, the number of the limiting blocks 32 is four, two of the limiting blocks are located at the left side of the annular positioning groove 3 and at the front and back positions, the other two limiting blocks are correspondingly located at the right side of the annular positioning groove 3 and at the front and back positions, and the end screw part 22 is clamped between the four limiting blocks 32 and then is limited in the front and back directions in the circumferential direction.

When in use, the hoop 2 is sleeved into the annular positioning groove 3 of the hose 1, the clamping end 24 of the positioning long hole 23 is aligned with the positioning column 31 to be sleeved, the clamping band 21 is rotated to enable the rod part of the positioning column 31 to enter the positioning long hole 23, because the width of the rod part of the positioning column 31 is matched with the width of the positioning long hole 23, the axial limit of the clamping band 21 is realized, when the clamping band 21 rotates to the designed position, the end screw part 22 is clamped between the four limit blocks 32, so that the limit of the end screw part 22 in the circumferential direction is realized, at the same time, the orientation of the bolt head is fixed, the hard pipe is inserted into the end head of the hose 1, then the bolt of the end head screw rod part 22 is screwed, can be connected to the hard tube with hose 1 fast on, clamp 2 can not produce the aversion phenomenon in the tightening process, has stopped the phenomenon of the indiscriminate assembly clamp of workman in the past, has laid a good foundation for clamp 2's standardized assembly.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change or modification made to the above embodiments according to the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
