Detailed Description

In an embodiment, as shown in fig. 1 to 4, a ventilation pipe joint for a tunnel construction ventilator includes a casing pipe base 1, the casing pipe base 1 is formed with two step holes 11 which are arranged in a left-right symmetrical manner and are large outside and small inside, and a through hole 12 communicating the two step holes 11, a notch 13 with an opening at the lower side is formed at the step in the middle of the step hole 11, a notch 14 with an opening at the lower side is formed at the outer end of the casing pipe base 1, the notch 14 is communicated with the notch 13 and is positioned at the outer side of the notch 13, two lugs 15 arranged in the front and at the back are formed on the notch 14, and the two lugs 15 are fastened through bolts 2;

the large end hole of the step hole 11 is internally sleeved with a C-shaped clamping ring 3, the clamping ring 33 is inserted and sleeved on the outer wall of the corresponding vent pipe 9, and the inner end of the vent pipe 9 extends into the small end hole of the step hole 11.

Furthermore, the inner wall of the clamping ring 3 is formed with a plurality of axially-distributed grooves 31.

More specifically, the upper end of the bushing base 1 is formed with a connecting seat 16, and the connecting seat 16 is formed with a plurality of connecting holes 17.

Furthermore, the slotted 13 is internally sleeved with a C-shaped elastic snap ring 4, the outer wall of the ventilation pipe 9 is formed with an annular groove 91, and the elastic snap ring 4 is inserted in the annular groove 91.

Furthermore, a plurality of arc-shaped retaining strips 18 are formed on the inner wall of the outer end of the stepped hole 11, and the clamping ring 3 is positioned between the arc-shaped retaining strips 18 and the elastic clamping ring 4.

Furthermore, a plurality of axially extending through grooves 41 which are uniformly distributed on the circumference are formed on the inner wall of the elastic snap ring 4; and the outer walls of the two ends of the elastic snap ring 4 are respectively provided with a handle 42.

The working principle is as follows: firstly, putting a clamping ring 3 into an outer end large hole of a stepped hole 11;

secondly, the end of the vent pipe 9 passes through the clamping ring 3 and extends into the small end of the stepped hole 11;

thirdly, tightening the bolt 2, driving the two support lugs 15 to approach each other by the bolt 2, driving the outer wall of the sleeve base positioned outside the slot 13 to press inwards and shrink the clamping ring 3, shrinking the clamping ring 3 and tightly embracing the outer wall of the ventilation pipe 9 so as to fixedly connect the ventilation pipe with the sleeve base, and fixing the connecting seat 16 above the sleeve base on the tunnel wall through screws;

fourthly, the two ends of the elastic snap ring 14 are opened through the pull handle 42 and then inserted into the annular groove of the ventilation pipe 9; the snap ring 14 limits the large axial swing of the vent tube and also limits the movement of the clamping ring 3.

Finally, the above embodiments are only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
