Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel water pipes, in particular to a stainless steel water pipe which is easy to expand. Background Art

[0002] Stainless steel water pipes are the best direct drinking water delivery pipes. They have a very low leakage rate and can save precious water resources. In the 1980s, the water pipe leakage rate was about 17%. After switching to stainless steel water pipes, the leakage rate dropped to 7%.

[0003] First of all, stainless steel water pipes are suitable for home decoration, construction projects, commercial facilities, industrial fields and public facilities. Stainless steel water pipe systems often need to adapt to changes in various layouts and needs to facilitate the adjustment and connection of stainless steel water pipes. When the stainless steel water pipes are connected at a long distance, an external water pipe is required for the stainless steel water pipes. However, when the existing stainless steel water pipes are connected, two stainless steel water pipes are butt-jointed and fixed with nuts and bolts. However, after long-term use of the stainless steel water pipes, staff are required to regularly maintain and replace the stainless steel water pipes to check the sealing of the butted water pipes and whether the water pipes are flowing. Since the butt joint is fixed with nuts and bolts, staff are required to tighten the nuts and bolts back and forth, which increases the efficiency of maintenance and replacement of the stainless steel water pipes. Long-term tightening of the nuts and bolts may cause leakage at the butt joint of the two stainless steel water pipes, resulting in a large waste of water resources, and the connection of the two stainless steel water pipes is more troublesome. Therefore, a stainless steel water pipe that is easy to expand is proposed. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides an easily expandable stainless steel water pipe, which solves the problems of inconvenient docking of two stainless steel water pipes, troublesome disassembly and low efficiency of maintenance and replacement of stainless steel water pipes by staff.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stainless steel water pipe that is easy to expand, comprising a first water pipe, the outside of the first water pipe is connected to a first flange, the outside of the first flange is installed with a first clamping block, the outside of the first clamping block is provided with a third ring, the outside of the third ring is installed with a second clamping block, the outside of the third ring is connected with a second flange, the inside of the second flange is provided with a second water pipe, the outside of the first water pipe is sleeved with a second ring, the outside of the second ring is installed with a cylinder, the outside of the cylinder is sleeved with the first ring, the top of the cylinder is connected to a connecting rod, the outside of the connecting rod is provided with a spring, the top of the connecting rod is installed with a rectangular block, one end of the outside of the first water pipe is distributed with a first sealing ring and a second sealing ring, the outside of the first flange is installed with a first convex block, the top of the outside of the first convex block is fixedly provided with a first slider, the outside of the second flange is provided with a second convex block, and the outside of the second convex block is installed with a second slider.

[0006] Preferably, both ends of the first water pipe and the second water pipe are provided with threads, and the first water pipe and the second water pipe are threadedly connected.

[0007] Preferably, the first flange and the second flange are both provided with long grooves on their exteriors, and the first protrusion and the first sliding block vertically slide in the long grooves.

[0008] Preferably, arc-shaped grooves are formed inside the first flange and the second flange, and upper and lower sides of the arc-shaped grooves are in contact with the top and bottom of the first protrusion.

[0009] Preferably, grooves are provided on both sides of the outside of the third ring, and the outsides of the first clamping block and the second clamping block are in contact with both sides of the grooves.

[0010] Preferably, a circular hole is formed on the outside of the first circular ring, and the connecting rod slides vertically in the circular hole.

[0011] Preferably, the second ring is made of rubber and is in a semicircular arc shape, and the outer contacts of a plurality of the second rings are in a circular ring shape.

[0012] Preferably, one end of the spring is installed on the top of the rectangular block, and the other end of the spring is in contact with the outer side of the first circular ring.

[0013] Preferably, there are multiple springs, and the multiple springs are distributed in a ring shape on the outer side of the first flange.

[0014] Preferably, one side of the first flange and the second flange contacts two sides of the outside of the third ring, and the outside of the first sealing ring contacts the outside of the second sealing ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention enables the outside of the first flange to contact the outside of the second flange through the first water pipe and the first flange, so that the first protrusion and the first slider enter the long groove. When the first protrusion and the first slider slide to the position of the circular arc groove opened in the second flange, the first water pipe is rotated to drive the first protrusion and the first slider to rotate, and the first slider is fixed through the circular arc groove. At the same time, the first flange drives multiple first clamping blocks installed externally to be clamped into the groove opened on the outer side of the third circular ring. At this time, the first water pipe is in contact with the outside of the second water pipe. By rotating the first water pipe, the internal threads of the first water pipe and the second water pipe are connected.

[0027] The above scheme is adopted: by installing the first flange 2 on the outer bottom of the first water pipe 1, and installing the second water pipe 5 on the outer side of the second flange 4, the staff picks up the first water pipe 1 and the first flange 2 to make the outer side of the first flange 2 contact with the outer side of the second flange 4, so that the first protrusion 15 and the first slider 16 installed on the outer side of the first flange 2 enter the long groove opened on the outer side of the second flange 4, and make the first protrusion 15 and the first slider 16 slide vertically into the inner side of the long groove. When the first protrusion 15 and the first slider 16 slide to the position of the arc groove opened inside the second flange 4, the first water pipe 1 is rotated to drive the first flange 2, and the first protrusion 15 and the first slider 16 are driven to rotate through the first flange 2, so that the first slider 16 rotates along the upper and lower sides of the arc groove, and the first slider 16 is fixed through the arc groove. At the same time, the first flange 2 drives the multiple first clamping blocks 19 installed on the outside to be clamped into the groove opened on the outer side of the third ring 3. At this time, the first water pipe 1 contacts the outer side of the second water pipe 5, and the first water pipe 1 is rotated to make the first water pipe 1 and the inner side of the second water pipe 5 Threaded connection, at the same time, the first water pipe 1 squeezes the first sealing ring 13 installed on the outside to contact with the second sealing ring 14, thereby improving the sealing performance of the joint between the first water pipe 1 and the second water pipe 5 to prevent water leakage during long-term use. When the first water pipe 1 and the second water pipe 5 need to be connected to the stainless steel water pipe at both ends, the stainless steel water pipe to be connected is contacted with the first water pipe 1 or the second water pipe 5, and the stainless steel water pipe is rotated to make the stainless steel water pipe and the first water pipe 1 or the second water pipe 5 threadedly connected. At the same time, the first ring 6 is pulled to drive the second ring 12 to move along the outside of the first water pipe 1 or the second water pipe 5 to the joint. The second ring 12 contacts the outside of the connected stainless steel water pipe, so that the second ring 12 pushes the cylinder 10 to move outward along the circular hole opened on the outside of the first ring 6. At the same time, the cylinder 10 squeezes the spring 9 to be compressed, so that the second ring 12 fits with the outside of the connected stainless steel water pipe, and the gap of the stainless steel water pipe connected to the first water pipe 1 or the second water pipe 5 is wrapped by the second ring 12, thereby preventing water leakage during use.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, both ends of the first water pipe 1 and the second water pipe 5 are provided with threads, and the first water pipe 1 and the second water pipe 5 are threadedly connected.

[0029] The above scheme is adopted: threads are provided at both ends of the first water pipe 1 and the second water pipe 5, which facilitates the connection between the first water pipe 1 and the second water pipe 5, and both ends of the first water pipe 1 and the second water pipe 5 can be externally connected with stainless steel water pipes to meet the places with certain requirements on length, thereby improving the flexibility of the first water pipe 1 and the second water pipe 5.

[0030] like Figure 1 , Figure 2 , Figure 3, Figure 5 and Figure 6 As shown, the first flange 2 and the second flange 4 are provided with long grooves on their exteriors, and the first protrusion 15 and the first slider 16 slide vertically in the long grooves; the first flange 2 and the second flange 4 are provided with arc-shaped grooves on their interiors, and the upper and lower sides of the arc-shaped grooves are in contact with the top and bottom of the first protrusion 15;

[0031] Grooves are provided on both sides of the outside of the third ring 3, and the outsides of the first clamping block 19 and the second clamping block 20 are in contact with both sides of the grooves; one side of the first flange 2 and the second flange 4 are in contact with both sides of the outside of the third ring 3, and the outside of the first sealing ring 13 is in contact with the outside of the second sealing ring 14.

[0032] The above scheme is adopted: the first flange 2 and the second flange 4 are provided with a long groove on the outside, and when the first water pipe 1 and the second water pipe 5 are connected, the first water pipe 1 and the second water pipe 5 drive the first protrusion 15, the first slider 16, the second protrusion 17 and the second slider 18 to contact each other, so that the first protrusion 15, the first slider 16, the second protrusion 17 and the second slider 18 enter the inside of the first water pipe 1 and the second water pipe 5 along the long groove, which is convenient for the connection between the first water pipe 1 and the second water pipe 5. At the same time, the first flange 2 and the second flange 4 are provided with an arc groove on the inside, and when the first water pipe 1 and the second water pipe 5 are rotated to drive the first flange 2 and the second flange 4 to rotate, the first protrusion 1 5. The second protrusion 17 drives the first slider 16 and the second slider 18 to rotate along the arc groove respectively, so that the first flange 2 and the second flange 4 are fixed. Through the grooves opened on both sides of the outside of the third ring 3, when the first flange 2 and the second flange 4 are in contact, the first clamping blocks 19 and the second clamping blocks 20 are driven to be clamped into the grooves. At the same time, the first water pipe 1 and the second water pipe 5 are docked to squeeze the first sealing ring 13 and the second sealing ring 14, so that the first sealing ring 13 and the second sealing ring 14 fit together, thereby improving the overall sealing performance when the first water pipe 1 and the second water pipe 5 are docked, reducing the occurrence of water leakage between the first water pipe 1 and the second water pipe 5, and reducing the waste of water resources.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a circular hole is opened on the outside of the first circular ring 6, and the connecting rod 7 slides vertically in the circular hole; the second circular ring 12 is made of rubber, and the second circular ring 12 is semicircular, and the outer contact of multiple second circular rings 12 is circular;

[0034] One end of the spring 9 is installed on the top of the rectangular block 8 , and the other end of the spring 9 contacts the outer side of the first circular ring 6 ; there are multiple springs 9 , and the multiple springs 9 are distributed in an annular shape on the outer side of the first flange 2 .

[0035] The above scheme is adopted: a circular hole is opened on the outside of the first circular ring 6. When the stainless steel water pipe is docked, the inner wall of the second circular ring 12 contacts the outside of the stainless steel water pipe, and the second circular ring 12 is squeezed to push the cylinder 10 to move outward along the circular hole opened on the outside of the first circular ring 6. At the same time, a spring 9 is installed between the first circular ring 6 and the rectangular block 8. When the cylinder 10 moves outward, the squeezing spring 9 is compressed, so that the second circular ring 12 fits the outside of the docked stainless steel water pipe. The second circular ring 12 is made of rubber and has very good elasticity, that is, it can be deformed under the action of external force, but can return to its original shape after the external force is removed. The rubber material has waterproof performance. When the stainless steel water pipe is docked, the first circular ring 6 is pulled to drive the whole to move toward the docking point of the stainless steel water pipe. Because the stainless steel water pipe will have some gaps on the surface after the docking is completed, the second circular ring 12 is moved to the gap at this time, and the sealing effect of the docking point is increased through the material of the second circular ring 12.

[0036] The working principle and use process of the present invention:

[0037] First, when the stainless steel water pipe needs to be docked in the required occasion, the first flange 2 is installed on the outer bottom of the first water pipe 1, and the second water pipe 5 is installed on the outside of the second flange 4. The staff picks up the first water pipe 1 and the first flange 2 to make the outside of the first flange 2 contact with the outside of the second flange 4, so that the first protrusion 15 and the first slider 16 installed on the outside of the first flange 2 enter the long groove opened on the outside of the second flange 4, and the first protrusion 15 and the first slider 16 slide vertically into the long groove. When the first protrusion 15 and the first slider 16 slide to the position of the arc groove opened in the second flange 4, the first water pipe 1 is rotated to drive the first flange 2, and the first protrusion 15 and the first slider 16 are driven to rotate through the first flange 2, so that the first slider 16 rotates along the upper and lower sides of the arc groove, and the first slider 16 is fixed through the arc groove. At the same time, the first flange 2 drives the multiple first clamping blocks 19 installed on the outside to be clamped into the groove opened on the outside of the third ring 3. At this time, the first water pipe 1 contacts the outside of the second water pipe 5. By rotating the first water pipe 1, the first water pipe 1 and the first water pipe 5 are connected. The internal thread connection of the second water pipe 5, at the same time, the first water pipe 1 squeezes the first sealing ring 13 installed on the outside to contact with the second sealing ring 14, thereby improving the sealing performance of the joint between the first water pipe 1 and the second water pipe 5, and preventing water leakage during long-term use. When the first water pipe 1 and the second water pipe 5 need to be connected to the stainless steel water pipe at both ends, the stainless steel water pipe to be connected is contacted with the first water pipe 1 or the second water pipe 5, and the stainless steel water pipe is rotated to make the stainless steel water pipe and the first water pipe 1 or the second water pipe 5 threadedly connected, and at the same time, the first ring 6 is pulled to drive the second ring 12 to move along the outside of the first water pipe 1 or the second water pipe 5 to the joint, and the second ring 12 contacts the outside of the stainless steel water pipe to be connected, so that the second ring 12 pushes the cylinder 10 to move outward along the circular hole opened on the outside of the first ring 6, and at the same time, the cylinder 10 squeezes the spring 9 to be compressed, so that the second ring 12 fits with the outside of the stainless steel water pipe to be connected, and the gap of the stainless steel water pipe connected to the first water pipe 1 or the second water pipe 5 is wrapped by the second ring 12, thereby preventing water leakage during use.
