AI Technical Summary
After the existing double-wall corrugated pipe connection device settles on the foundation, the socket connection will be displaced, resulting in seal failure and pipeline leakage.
A double-wall corrugated tube snap-sealing connection device is designed, and the engagement and fixing and sealing are achieved by setting an inlet channel and an outlet channel on the corrugated tube body and a sealing connection structure at the connection, including a rotatable upper sealing shell and a lower sealing shell, a fixing rod and an elastic clamp, which realizes engagement and fixing and sealing.
The device maintains the relatively fixed state of the corrugated pipe through the connection between the inlet channel and the outlet channel, and at the same time, the engagement and sealing functions of the sealing connection structure avoids displacement and leakage problems caused by foundation settlement.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Please refer to Figures 1-6 As shown, the present utility model is a double-wall corrugated pipe buckle sealing connection device, including two corrugated pipe bodies 1. A plurality of grooves 11 are provided on the surface of the corrugated pipe body 1, and the plurality of grooves 11 are equidistantly arranged. An inlet channel 12 is provided on one side of the corrugated pipe body 1, and an outlet channel 13 is provided on the side of the corrugated pipe body 1 away from the inlet channel 12. The inlet channel 12 and the outlet channel 13 communicate with the inner cavity of the corrugated pipe body 1, and the radius of the outlet channel 13 is smaller than that of the inlet channel 12. The outer diameter of the outlet channel 13 is the same as the inner diameter of the inlet channel 12, so that different corrugated pipe bodies 1 can be connected through the inlet channel 12 and the outlet channel 13.
[0028] A connection and sealing structure 2 is provided between adjacent corrugated pipe bodies 1. The connection and sealing structure 2 includes an upper sealing shell 21 and a lower sealing shell 22. Connection seats 28 are provided on the surfaces of the upper sealing shell 21 and the lower sealing shell 22. The upper sealing shell 21 and the lower sealing shell 22 are rotatably connected through the connection seats 28. On one side of the upper sealing shell 21 and the lower sealing shell 22 away from the connection seats 28, connection blocks 23 are provided. The connection blocks 23 on the surfaces of the upper sealing shell 21 and the lower sealing shell 22 can come into contact. Communication holes 24 are provided on the surface of each connection block 23. On the surface of the upper sealing shell 21, clamping grooves 25 are provided. The number of the clamping grooves 25 is two, and the two clamping grooves 25 are located on both sides of the connection block 23. On the surface of the lower sealing shell 22 at the corresponding position, a fixing rod 26 is provided. The position of the fixing rod 26 is adapted to the opening position of the clamping groove 25. The fixing rod 26 is arranged along the vertical direction, and an elastic clamping block 27 is elastically provided at the top of the fixing rod 26.
[0029] When using this double-wall corrugated pipe buckle sealing connection device to connect two corrugated pipe bodies 1. The outlet channel 13 of one corrugated pipe body 1 is connected to the inlet channel 12 of another corrugated pipe body 1, so that the inner cavities between different corrugated pipe bodies 1 are communicated. At the same time, the outlet channel 13 is inside the inlet channel 12. While communicating the inner cavities of the corrugated pipe bodies 1, it plays an auxiliary fixing role between the two corrugated pipe bodies 1. At this time, a connection and sealing structure 2 is provided between the joints of the two corrugated pipe bodies 1. The upper sealing shell 21 and the lower sealing shell 22 of the connection and sealing structure 2 are rotatably connected. The upper sealing shell 21 and the lower sealing shell 22 are sleeved on the surface of the joint of the corrugated pipe body 1. The upper sealing shell 21 and the lower sealing shell 22 can be engaged with the groove 11 on the surface of the corrugated pipe body 1, thereby assisting the connection and sealing structure 2 to be fixedly installed. Subsequently, the connection blocks 23 on the surfaces of the upper sealing shell 21 and the lower sealing shell 22 come into contact. The elastic clamping block 27 at the top of the fixing rod 26 on the lower sealing shell 22 deforms, so that the elastic clamping block 27 and the fixing rod 26 extend into the clamping groove 25. After extending into the clamping groove 25, the elastic clamping block 27 is restored under the action of its own elastic force. Therefore, the elastic clamping block 27 cannot be disengaged from the clamping groove 25 after restoration, and the upper sealing shell 21 and the lower sealing shell 22 are fixed. Subsequently, bolts are inserted into the communication holes 24 of the two connection blocks 23, and fixing nuts are threadedly connected to the surfaces of the bolts, so that the fixing nuts and the bolts are in close contact with the surfaces of the two connection blocks 23, thereby completing the fixation. The sealing connection structure can also position the two corrugated pipe bodies 1, so that the connection between the inlet channel 12 and the outlet channel 13 can be connected in a specified direction, and the two corrugated pipe channels are kept on the same straight line.
[0030] Working principle of the utility model: For the double-wall corrugated pipe buckle sealing connection device of the utility model, by providing a corrugated pipe body 1, an inlet channel 12 and an outlet channel 13 are arranged on both sides of the corrugated pipe body 1. The outer diameter of the outlet channel 13 is the same as the inner diameter of the inlet channel 12, so that two different corrugated pipe bodies 1 can be connected through the outlet channel 13 and the inlet channel 12, enabling the two corrugated pipe bodies 1 to be relatively fixed while the inner cavities are communicated; by providing a sealing connection structure, the upper sealing shell 21 and the lower sealing shell 22 of the sealing connection structure are rotatably arranged, so that the upper sealing shell 21 and the lower sealing shell 22 can be sleeved on the connection part of the two corrugated pipe bodies 1. Subsequently, the elastic clamping block 27 at the top of the fixing rod 26 can be engaged with the clamping groove 25 to complete the clamping and fixing between the upper sealing shell 21 and the lower sealing shell 22. The connection holes on the surfaces of the two connection blocks 23 coincide, and fixing bolts and fixing nuts can be arranged in the two connection holes for fixation; the upper sealing shell 21, the lower sealing shell 22 are engaged with the grooves 11 on the surfaces of the two corrugated pipe bodies 1, which not only achieves a sealing effect, but also the sealing connection structure assists in clamping the two corrugated pipe bodies 1.
