Technical Field

[0001] The utility model relates to the technical field of PRP pipes, in particular to PPR pipes with good port sealing performance. Background Technique

[0002] PPR pipes, also known as random copolymer polypropylene pipes, compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, have the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, long service life, etc., and are widely used in construction water supply and drainage, urban and rural water supply and drainage, urban gas, power and optical cable sheaths, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

[0003] During the use of existing PRP pipes, the hot melt connection method is usually adopted for connection, so as to ensure the sealing performance of the connection between pipes. However, the connection part usually does not have a protective structure, and the connection part is relatively fragile, and it is easy to be damaged and broken, thereby reducing the connection sealing performance. Therefore, we propose PPR pipes with good port sealing performance. Content of the Utility Model

Fixed strengthening mechanisms are fixedly sleeved on the outer sides of the surfaces of the first pipe and the second pipe close to each other, and connection bolts are arranged between the fixed strengthening mechanisms.

[0007] In a further technical solution, a movable strengthening mechanism is sleeved on the outer side of the surface of the connection position between the first pipe and the second pipe.

[0008] In a further technical solution, the fixed strengthening mechanism includes a fixed mounting plate, first fixed through holes are symmetrically opened on the surface of the fixed mounting plate, fixed connection blocks are symmetrically arranged on one side of the fixed mounting plate, and first fixed grooves are opened on the outer sides of the surfaces of the fixed connection blocks.

[0010] In a further technical solution, connection strengthening blocks are symmetrically arranged on the other side of the fixed mounting plate, and the bottom of the connection strengthening blocks is in mutual fit with the surface of the first pipe or the second pipe.

[0011] In a further technical solution, the movable strengthening mechanism includes a first connection disk and a second connection disk. A number of connection strengthening rods are arranged between the first connection disk and the second connection disk. Second fixing grooves are formed on the surfaces of the first connection disk and the second connection disk away from each other. Fixing through grooves are formed inside the first connection disk and the second connection disk. Second fixing through holes are formed on the surfaces of the first connection disk and the second connection disk.

[0012] In a further technical solution, the inner side of the second fixing groove is in mutual fit with the end surface of the fixed connection block, and the fixing through groove is in mutual fit with the outer side of the surface of the first pipe or the second pipe.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Through the mutual cooperation between the fixed strengthening mechanism and the connection bolts, when the first pipe and the second pipe are connected and fixed by the hot melting method, the connection between the first pipe and the second pipe can be strengthened through the connection cooperation between the fixed strengthening mechanism and the connection bolts, so that the first pipe and the second pipe are stably connected, and stable sealing performance can be maintained between the first pipe and the second pipe, and the operation is convenient;

[0029] After the connection between the first pipe 1 and the second pipe 2 is completed, it is convenient to insert the connection bolt 4 into the inner side of the first fixing through hole 7 and make the connection, so as to connect the fixing and strengthening mechanisms 3. At the same time, the connection bolt 4 can block the outside, avoiding direct damage to the connection between the first pipe 1 and the second pipe 2.

[0030] In another embodiment, as Figure 2 shown, the bottom of the fixed connection block 8 is in mutual contact with the outer surface of the first pipe 1 or the second pipe 2, and the inner side of the first fixing groove 9 is in mutual contact with the outer surface of the connection bolt 4.

[0031] It is convenient for the fixed connection block 8 to be in mutual contact with the first pipe 1 or the second pipe 2, so that the connection between the fixing and strengthening mechanism 3 and the first pipe 1 or the second pipe 2 is in a stable state.

[0032] In another embodiment, as Figure 2 shown, connection strengthening blocks 10 are symmetrically arranged on the other side of the fixed mounting plate 6, and the bottom of the connection strengthening blocks 10 is in mutual contact with the surface of the first pipe 1 or the second pipe 2.

[0033] It is convenient for the connection strengthening blocks 10 to be in mutual contact with the first pipe 1 or the second pipe 2, which can further improve the connection stability between the fixing and strengthening mechanism 3 and the first pipe 1 or the second pipe 2, and the operation is convenient.

[0034] In another embodiment, as Figure 2 shown, the movable strengthening mechanism 5 includes a first connection disk 11 and a second connection disk 12. There are several connection strengthening rods 16 between the first connection disk 11 and the second connection disk 12. Second fixing grooves 14 are formed on the surfaces of the first connection disk 11 and the second connection disk 12 away from each other. Fixing through slots 15 are formed inside the first connection disk 11 and the second connection disk 12. Second fixing through holes 13 are formed on the surfaces of the first connection disk 11 and the second connection disk 12.

[0035] It is convenient for the first connection disk 11 and the second connection disk 12 to be sleeved on the outer surfaces of the ends of the first pipe 1 and the second pipe 2. At the same time, the end of the fixed connection block 8 is inserted into the inner side of the second fixing groove 14.

Then, the second connecting disc 12 is sleeved on the outer side of the end surface of the first pipe 1, so that the second fixed groove 14 can be sleeved on the outer side of the end surface of the fixed connecting block 8. Then, the second pipe 2 drives the fixed strengthening mechanism 3, the fixed connecting block 8 and the connecting strengthening block 10 to move, so that the end of the second pipe 2 can be inserted into the inside of the first pipe 1.
