Description

Technical Field

[0001] The utility model relates to the technical field of pipe interfaces, and more specifically, to a pipe connection port capable of improving the pressure resistance of a pipe expansion port. Background Art

[0002] When laying plastic pipes underground, two adjacent plastic pipes need to be connected. The traditional connection method is to first process a pipe interface into a flared opening by hot-melt processing, and then insert another plastic pipe into the flared opening to achieve the connection between adjacent plastic pipes. However, the pipe wall at the flared opening after hot-melt molding becomes thinner and its compressive strength is not high. Therefore, a pipe connector is needed to enhance the strength of the flared opening.

[0003] After searching the existing related patent: CN218094868U, a pipe connection port is disclosed. The prior art connects the first connecting plate with the second connecting plate through a first supporting bolt, so that the first arc plate and the second arc plate clamp the pipe, thereby effectively preventing the soil layer from fracturing the pipe expansion port.

[0004] However, the inventors have discovered that the prior art has the following problems during use: although the prior art fixes the connector with bolts, only the side of the arc plate close to the connector has the best compressive resistance. As a result, when the side of the arc plate away from the connector is sunken due to soil settlement, displacement or excessive extrusion pressure, the sunken side of the arc plate will directly act on the pipe expansion, thereby affecting the protective effect of the arc plate on the pipe expansion and the compressive strength of the pipe expansion. In response to the above problems, the inventors have designed a pipe connection that has the function of improving the compressive strength of the pipe expansion. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pipe connection port which ensures the protective effect of the arc reinforcement plate on the pipe expansion and the pressure resistance of the pipe expansion, thereby improving the pressure resistance of the pipe expansion.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pipe connection port with the function of improving the pressure resistance of the pipe expansion port, comprising a pipe expansion port and two arc reinforcement plates arranged on the outside of the pipe expansion port, wherein connecting pieces are fixedly installed on the opposite side surfaces of the two arc reinforcement plates, wherein an arc-shaped inner cavity is formed in the arc reinforcement plate, wherein the arc-shaped inner cavity is arranged on the side of the arc reinforcement plate away from the connecting piece, wherein a plurality of support plates are fixedly connected to the inner wall of the arc-shaped inner cavity away from the connecting piece, wherein a support assembly for supporting the support plates is provided in the arc-shaped inner cavity, wherein the support assembly comprises two mounting plates, wherein the two mounting plates are fixedly mounted on the arc-shaped inner wall of the arc-shaped inner cavity close to the connecting piece, wherein an arc-shaped sliding rod is fixedly installed between the two mounting plates, wherein an arc-shaped sliding sleeve is provided on the outer surface of the arc-shaped sliding rod, wherein two hinged seats are fixedly connected to the outer surface of the arc-shaped sliding sleeve, and a first push plate is hingedly connected between the top hinged seat and the lower surface of the support plate.

[0008] The utility model is further configured as follows: the two arc reinforcement plates are arranged in a mirror image and wrapped around the outer side of the expanded opening of the pipe.

[0009] The utility model is further configured as follows: a plurality of mounting bolts are arranged between two adjacent connecting members, and the two adjacent connecting members are fixed by the mounting bolts.

[0010] The utility model is further configured as follows: a plurality of compression chambers are provided in the circular arc reinforcement plate, the compression chambers are arranged on one side of the circular arc reinforcement plate close to the connecting piece, and compression sliding rods are arranged in the compression chambers.

[0011] The utility model is further configured as follows: one end of the compression slide rod slides through the arc-shaped inner cavity, and a second push plate is hingedly connected between the bottom hinge seat and one end of the compression slide rod located in the arc-shaped inner cavity.

[0012] The utility model is further configured as follows: one end of the compression slide rod located in the compression chamber is fixedly connected to a compression plate, the compression plate slides in the compression chamber, a tension spring is fixedly connected between the compression plate and the inner wall of the compression chamber, and the tension spring is movably sleeved on the outer surface of the compression slide rod.

[0013] The utility model is further configured as follows: a compression outer plate is inlaid on the side surface of the arc reinforcement plate, and one side of the compression outer plate extends into the arc-shaped inner cavity.

[0014] The utility model is further configured as follows: a bending groove is provided on one side surface of the compression outer plate located in the arc-shaped inner cavity.

[0015] The advantage of the utility model is that when the side of the circular arc reinforcement plate away from the connecting piece is affected by soil settlement, displacement or excessive extrusion pressure, the first push plate pushes the arc sliding sleeve on the arc sliding rod to move toward the side of the connecting piece, thereby transferring the extrusion pressure of the soil layer on the side of the circular arc reinforcement plate away from the connecting piece to the side close to the connecting piece, and avoiding as much as possible the situation where the side of the circular arc reinforcement plate away from the connecting piece is pressed and depressed and directly acts on the expanded part of the pipe, further ensuring the protective effect of the circular arc reinforcement plate on the expanded part of the pipe and the compressive strength of the expanded part of the pipe.

DETAILED DESCRIPTION

[0021] See also Figure 1-4 , the utility model provides the following technical solutions:

[0022] Specifically, it refers to a pipe connection port with the function of improving the pressure resistance of the pipe expansion portion, including a pipe expansion 1 and two arc reinforcement plates 2 arranged on the outside of the pipe expansion 1, the two arc reinforcement plates 2 are arranged in a mirror image and wrapped around the outside of the pipe expansion 1, so the pipe expansion is protected by the arc reinforcement plates 2, and connectors 3 are fixedly installed on the opposite side surfaces of the two arc reinforcement plates 2, and multiple mounting bolts 4 are arranged between two adjacent connectors 3, so by screwing the mounting bolts 4, the two adjacent connectors 3 can be fixed together, thereby completing the fixing of the two arc reinforcement plates 2 on the outer surface of the pipe expansion 1.

[0023] Specifically, an arc-shaped inner cavity 5 is opened in the arc reinforcement plate 2, and the arc-shaped inner cavity 5 is arranged on the side of the arc reinforcement plate 2 away from the connecting piece 3. A plurality of support plates 6 are fixedly connected to the inner wall of the arc-shaped inner cavity 5 away from the connecting piece 3. A plurality of support components for supporting the plurality of support plates 6 are arranged in the arc-shaped inner cavity 5, and the support components include two mounting plates 7, and the two mounting plates 7 are fixedly mounted on the arc-shaped inner wall of the arc-shaped inner cavity 5 close to the connecting piece 3. An arc-shaped sliding rod 8 is fixedly mounted between the two mounting plates 7, and an arc-shaped sliding sleeve 9 is slidingly sleeved on the outer surface of the arc-shaped sliding rod 8. Two hinge seats 10 are fixedly connected to the outer surface of the arc-shaped sliding sleeve 9, and a first push plate 11 is hinged between the top hinge seat 10 and the lower surface of the support plate 6;

[0024] When the side of the arc reinforcement plate 2 away from the connecting piece 3 is affected by soil settlement, displacement or excessive extrusion pressure, the top surface of the arc reinforcement plate 2 will be concave, and the concave arc reinforcement plate 2 will exert pressure on the support plate 6, causing the support plate 6 to displace toward the side close to the pipe expansion 1. At the same time, the support plate 6 will form a thrust on the first push plate 11, causing the first push plate 11 to push the arc sliding sleeve 9 on the arc sliding rod 8 to displace toward the side of the connecting piece 3, thereby transferring the soil layer’s extrusion pressure on the side of the arc reinforcement plate 2 away from the connecting piece 3 to the side close to the connecting piece 3, and trying to avoid the situation where the side of the arc reinforcement plate 2 away from the connecting piece 3 is directly affected by the concave pressure and acts on the pipe expansion 1, further ensuring the protective effect of the arc reinforcement plate 2 on the pipe expansion 1 and the compressive strength of the pipe expansion 1.

[0025] Specifically, a plurality of compression chambers 13 are provided in the arc reinforcement plate 2, and the compression chamber 13 is provided on one side of the arc reinforcement plate 2 close to the connecting member 3. A compression slide bar 14 is provided in the compression chamber 13, and one end of the compression slide bar 14 slides through the arc inner chamber 5. A second push plate 12 is hingedly connected between the bottom hinge seat 10 and one end of the compression slide bar 14 located in the arc inner chamber 5. One end of the compression slide bar 14 located in the compression chamber 13 is fixedly connected with a compression plate 15, and the compression plate 15 slides in the compression chamber 13. The compression plate A tension spring 16 is fixedly connected between 15 and the inner wall of the compression chamber 13. The tension spring 16 is movably sleeved on the outer surface of the compression slide bar 14. When the tension spring 16 is not affected by the tension force, the tension spring 16 will form a tension force on the compression plate 15, so that the initial position of the compression plate 15 is close to the side of the arc-shaped inner chamber 5. In this way, the compression slide bar 14 will form a supporting effect on the second push plate 12, so that the first push plate 11 forms a supporting effect on the support plate 6, further improving the compressive resistance of the arc reinforcement plate 2 to the pipe expansion 1;

[0026] When the arc sleeve 9 moves toward one side of the connecting member 3 on the outer surface of the arc slide rod 8, the arc sleeve 9 will apply pressure to the second push plate 12, so that the second push plate 12 pushes the compression slide rod 14 to shrink into the shrinkage cavity 13. At the same time, the compression plate 15 slides in the compression cavity 13, and the tension spring 16 is stretched. In this way, when the tension spring 16 releases the reaction force, the compression slide rod 14 can apply a reverse thrust to the second push plate 12. Therefore, the first push plate 11 forms a supporting effect on the support plate 6, thereby avoiding the problem of serious depression on the side of the arc reinforcement plate 2 away from the connecting member 3 as much as possible.

[0027] Specifically, a compression outer plate 17 is inlaid on the side of the arc reinforcement plate 2, and one side of the compression outer plate 17 extends into the arc-shaped inner cavity 5. At the same time, the compression outer plate 17 is made of elastic plastic material. A bending groove 18 is provided on the surface of one side of the compression outer plate 17 located in the arc-shaped inner cavity 5. In this way, when the side of the arc reinforcement plate 2 is squeezed and concave, the concave side will exert pressure on the compression outer plate 17, so that the compression outer plate 17 is bent with the bending groove 18 as the bending point.

[0028] The working principle of the pipe connection port with improved compressive strength at the pipe expansion point provided by the utility model is as follows: when the side of the arc reinforcement plate 2 away from the connecting piece 3 is affected by soil settlement, displacement or excessive extrusion pressure, the top surface of the arc reinforcement plate 2 will be concave, and the concave arc reinforcement plate 2 will exert pressure on the support plate 6, so that the support plate 6 is displaced toward the side close to the pipe expansion point 1, and at the same time, the support plate 6 will form a thrust on the first push plate 11, so that the first push plate 11 pushes the arc sliding sleeve 9 on the arc sliding rod 8 to move toward the side of the connecting piece 3, thereby transferring the soil layer The extrusion force on the side of the arc reinforcement plate 2 away from the connecting piece 3 is transferred to the side close to the connecting piece 3.
