For this connecting structure of the hollow wall winding pipe, when connecting pipelines, the interface is not easily deformed, and the pipeline connection has good sealing performance.

[0019] Please refer to Figures 1 to 4 , Figure 1 This is the overall structural schematic diagram of a connecting device for a winding structure wall pipeline of the present utility model, Figure 2 This is another overall structural schematic diagram of a connecting device for a winding structure wall pipeline of the present utility model, Figure 3 This is the front view of the overall connecting device for a winding structure wall pipeline of the present utility model, Figure 4 This is the sectional view of the overall connecting device for a winding structure wall pipeline of the present utility model.

[0020] A connecting device for a winding structure wall pipeline of the present utility model includes a hollow winding pipe body 101 and a connecting component 102. The connecting component 102 includes a support mechanism 103, a connecting pipe 104, a flange 105, a positioning bolt 106, a hoop 107 and a sealing strip 108. The support mechanism 103 includes a support ring 109, a support plate 110, a cross 111, a spring 112, a connecting rod 113 and a pin 114. The hoop 107 includes a semi - circle body 115, a rotating shaft 116, a connecting plate 117 and a fastener 118. Through the foregoing solution, the problem that the contact surface between the support ring 109 of the existing connecting structure of the hollow wall winding pipe and the pipeline is small, resulting in the inability to stably connect the pipeline and the connecting pipe 104 in cooperation with the hoop 107 when supporting the pipeline is solved.

[0021] For this specific embodiment, by installing the hollow winding pipe body 101 in municipal engineering, wastewater can be effectively discharged.

[0022] Among them, the support mechanism 103 is arranged on one side of the hollow winding pipe body 101. The connecting pipe 104 is slidably connected to the hollow winding pipe body 101 and is located on the side of the hollow winding pipe body 101. The flange 105 is fixedly connected to the connecting pipe 104 and is located on the side of the connecting pipe 104. The positioning bolt 106 is threadedly connected to the flange 105 and is located on one side of the flange 105. The hoop 107 is arranged on the side of the hollow winding pipe body 101. When it is necessary to connect two hollow winding pipe bodies 101, first, the inner wall of the hollow winding pipe body 101 is supported by the support mechanism 103, and the connecting pipe 104 on the flange 105 is slid into the hollow connecting pipe 104 body. At this time, the hoop 107 is used to fix the positions of the hollow winding pipe body 101 and the connecting pipe 104. After the fixation on one side is completed, another group of hollow winding pipe bodies 101 is slid onto the connecting pipe 104 on the other side of the flange 105, and the hoop 107 is used again to fix the positions of the hollow winding pipe body 101 and the connecting pipe 104. At the same time, the positioning bolt 106 is rotated clockwise. The positioning bolt 106 passes through the flange 105 to fix the two flanges 105, so that the positions of the two hollow winding pipe bodies 101 on both sides of the flange 105 can be connected, thus solving the problem that the contact surface between the support ring 109 of the existing connection structure of the hollow-wall winding pipe and the pipe is small, resulting in the inability to cooperate with the hoop 107 to stably connect the pipe and the connecting pipe 104 when supporting the pipe.

[0023] Secondly, the sealing strip 108 is fixedly connected to the hollow winding pipe body 101 and is located on the side of the hollow winding pipe body 101 close to the flange 105. The sealing strip 108 is used to seal the gap between the hollow winding pipe body 101 and the flange 105 to avoid accidents during use.

[0024] Again, the support ring 109 is fixedly connected to the hollow winding tube body 101 and is located on one side of the hollow winding tube body 101 close to the connecting pipe 104. The support plate 110 is fixedly connected to the support ring 109 and is located on one side of the support ring 109. The cross 111 is fixedly connected to the support plate 110 and is located on the inner wall of the support plate 110. The support ring 109 is installed at a position of the hollow winding tube body 101 close to the connecting pipe 104, and through the cooperation of the cross 111 and the support plate 110, the support ring 109 is fixed, and the strength of the support ring 109 is increased, and its service life is extended.

[0025] In addition, the spring 112 is fixedly connected to the hollow winding tube body 101 and is located on one side of the hollow winding tube body 101. The connecting rod 113 is fixedly connected to the spring 112 and is slidably connected to the hollow winding tube body 101 and is located on one side of the spring 112. The bolt 114 is fixedly connected to the connecting rod 113 and passes through the connecting pipe 104 and is located at the bottom of the connecting rod 113. After using the hoop 107 to fix the hollow winding tube body 101 on the connecting pipe 104, the staff can pull the connecting rod 113 to drive the spring 112 to stretch. The bolt 114 at the bottom of the connecting rod 113 moves accordingly. The bolt 114 is aligned with the hollow winding tube body 101. At this time, the staff releases the connecting rod 113, so that the spring 112 drives the connecting rod 113 to retract, which can push the bolt 114 to move in the hollow winding tube body 101 and pass through the connecting pipe 104, and can cooperate with the hoop 107 to fix the position of the connecting pipe 104.

[0026] At the same time, the half-circle body 115 is slidably connected to the hollow winding tube body 101 and is located on the outside of the hollow winding tube body 101. The rotating shaft 116 is rotatably connected to the half-circle body 115 and is located on the side of the half-circle body 115. The connecting plate 117 is fixedly connected to the half-circle body 115 and is located on the side of the half-circle body 115. The fastener 118 is threadedly connected to the connecting plate 117 and passes through the connecting plate 117 to slide the connecting tube 104 into the hollow winding tube body. 101, the staff places the half-circle 115 on the hollow winding tube body 101 and rotates the rotating shaft 116 so that the half-circle 115 can wrap the central control winding tube body. At this time, the fastener 118 is right-turned, and the fastener 118 passes through the connecting plates 117 on the sides of the two half-circles 115, thereby fixing the position of the half-circle 115. At the same time, the half-circle 115 clamps the hollow winding tube body 101 and the connecting tube 104 to make the connection firm.

[0027] A connecting device for a winding structure wall pipeline of the present utility model. When it is necessary to connect two hollow winding pipe bodies 101, the support ring 109 is installed into the hollow winding pipe body 101, and through the cooperation of the cross 111 and the support plate 110, the support ring 109 is fixed. Then, the connecting pipe 104 on the flange 105 is slid into the hollow connecting pipe 104 body, and the connecting pipe 104 can abut against the support ring 109. At this time, the semi-circular body 115 is placed on the hollow winding pipe body 101, and the rotating shaft 116 is rotated so that the semi-circular body 115 can wrap the central control winding pipe body. At this time, the fastener 118 is rotated clockwise, and the fastener 118 passes through the connecting plate 117 on the sides of the two semi-circular bodies 115, thereby fixing the position of the semi-circular body 115. At the same time, the semi-circular body 115 clamps the hollow winding pipe body 101 and the connecting pipe 104 to make the connection firm. The worker can pull the connecting rod 113 to drive the spring 112 to stretch, and the pin 114 at the bottom of the connecting rod 113 moves accordingly. The pin 114 is aligned with the hollow winding pipe body 101. At this time, the worker releases the connecting rod 113, so that the spring 112 drives the connecting rod 113 to retract, which can push the pin 114 to move in the hollow winding pipe body 101 and pass through the connecting pipe 104, and can cooperate with the hoop 107 to fix the position of the connecting pipe 104. After one side is fixed, another group of the hollow winding pipe bodies 101 is slid onto the connecting pipe 104 on the other side of the flange 105, and the hoop 107 is used again to fix the positions of the hollow winding pipe body 101 and the connecting pipe 104. At the same time, the positioning bolt 106 is rotated clockwise, and the positioning bolt 106 passes through the flange 105 to fix the two flanges 105, thereby enabling the positions of the two groups of hollow winding pipe bodies 101 on both sides of the flange 105 to be connected, thus solving the problem that the contact surface between the support ring 109 of the existing connection structure of the hollow wall winding pipe and the pipeline is small, resulting in the inability to stably connect the pipeline and the connecting pipe 104 with the cooperation of the hoop 107 when supporting the pipeline.
