[0004] The above technology fixes two pipes by connecting the upper shell and the lower shell when in use. However, the use of this technology is too limited. It can only fix two pipes with the same diameter. If the pipes have different diameters, the two pipes can be connected by replacing the connecting pieces. It is impossible to connect two pipes of different sizes, and the pipe connecting pieces cannot be adjusted to connect different pipes. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the pipeline connector cannot be adjusted to connect different pipelines, and to propose an adjustable pipeline connector.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The utility model heats the PVC hose to make it suitable for sleeves of different sizes. Then, by twisting the second bolt, the second bolt is rotated in the mounting plate, and the movement of the second bolt is restricted by the fixing ring so that the second bolt is always perpendicular to the rotating rod, thereby preventing the second bolt from tilting and causing a crack between the rotating rod and the second bolt. Then, the second bolt causes the rotating rod to drive the rotating gear to rotate, thereby causing the rotating gear to push the stainless steel belt to reel, thereby sealing the PVC hose sleeved on the pipe and being suitable for connecting pipes of different sizes.

[0015] 2. The utility model rotates the first bolt to push the limiting block in the sliding groove to move toward the second bolt, so that the limiting block limits the rotation of the second bolt and prevents the stainless steel belt from releasing the restriction on the PVC hose.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 4 An adjustable pipe connector includes a PVC hose 1. The PVC hose 1 is thermoplastic. By heating the PVC hose 1, the PVC hose 1 is adapted to fit pipes of different sizes. Then, by cooling, the PVC hose 1 automatically sets its shape. A stainless steel strip 2 is provided on the outer wall of the PVC hose 1. The stainless steel strip 2 is provided with a placement groove 3 for pushing the stainless steel strip 2 to wrap around the PVC hose 1. A mounting plate 4 is fixedly mounted on the end of the stainless steel strip 2. The inner wall of the mounting plate 4 is provided with a reeling mechanism for reeling in the stainless steel strip 2 to compress the PVC hose 1.

[0023] The winding mechanism includes a rotating rod 10, a rotating gear 11 for driving one end of the stainless steel belt 2 to move is fixedly installed on the outer wall of the rotating rod 10, a second bolt 8 for driving the rotating rod 10 to rotate is fixedly installed on the end of the rotating rod 10, and a fixing ring 9 for limiting the movement of the second bolt 8 is provided on the outer wall of the second bolt 8. The stainless steel belt 2 is driven to move by the rotating gear 11, so that the radius of the circle surrounded by the stainless steel belt 2 gradually becomes smaller, thereby achieving the effect of sealing the PVC hose 1. The second bolt 8 is restricted by the fixing ring 9 so that the second bolt 8 is always perpendicular to the rotating rod 10, so that the rotating rod 10 and the second bolt 8 always maintain the same rotation speed, thereby preventing the second bolt 8 from rotating obliquely and causing cracks to appear at the connection between the second bolt 8 and the rotating rod 10;

[0024] The rotating rod 10 is rotatably arranged in the inner wall of the mounting plate 4, and the teeth of the lower end of the rotating gear 11 are arranged in the placement groove 3, which is convenient for pushing one end of the stainless steel belt 2 to move, thereby winding the stainless steel belt 2, and the rotating gear 11 and the placement groove 3 are used in conjunction with each other, and the fixing ring 9 is fixedly installed on the outer wall of the mounting plate 4;

[0025] A sliding groove 5 is provided in the mounting plate 4, in which a limiting block 7 is slidably provided. A side of the limiting block 7 close to the second bolt 8 is provided with an arc groove that fits with the second bolt 8. A first bolt 6 is rotatably installed on the right side wall of the limiting block 7.

[0026] The outer wall of the mounting plate 4 is provided with a bolt hole, and a nut is fixedly installed in the bolt hole provided in the mounting plate 4. The first bolt 6 is set in the nut. By screwing the first bolt 6, the first bolt 6 pushes the limiting block 7 to move. The limiting block 7 and the first bolt 6 are rotatably connected, and the rotation of the limiting block 7 is limited by the sliding groove 5, so as to ensure that the limiting block 7 slides in the sliding groove 5.

[0027] The second bolt 8 is rotatably mounted on the outer wall of the mounting plate 4 , and the center of the fixing ring 9 and the center of the rotating rod 10 are arranged in the same plane.

[0028] The functional principle of this utility model can be explained through the following operation modes:

[0029] By heating the PVC hose 1, the thermoplasticity of the PVC hose 1 can be used to sleeve the outer walls of pipes of different sizes, and then the second bolt 8 is screwed to rotate the second bolt 8 in the mounting plate 4, and the movement of the second bolt 8 is limited by the fixing ring 9 so that the second bolt 8 is always perpendicular to the rotating rod 10. Then the second bolt 8 drives the rotating rod 10 to rotate, so that the rotating rod 10 drives the rotating gear 11 to rotate, so that the rotating gear 11 pushes the stainless steel belt 2 to reel, so that the stainless steel belt 2 is tightly wrapped around the outer wall of the PVC hose 1, and then the first bolt 6 is screwed to push the limiting block 7 to move in the sliding groove 5 toward the second bolt 8, so that the limiting block 7 limits the rotation of the second bolt 8.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
