Description

Technical Field

[0001] The utility model relates to the technical field of butt joints, in particular to a metal pipe reducing butt joint. Background Art

[0002] In the fields of industry and construction, metal pipes are widely used to transport various fluid media. In practical applications, due to the needs of design, installation or maintenance, it is often necessary to connect metal pipes of different diameters.

[0003] When connecting two metal pipes of different diameters, the traditional metal pipe reducer needs to install and fix the metal pipes one by one. Whether it is connected by thread or flange, the connection efficiency is low and it is time-consuming and labor-intensive. Therefore, a metal pipe reducer is proposed. Utility Model Content

[0004] The utility model aims to provide a metal pipe reducing joint to solve the problems raised by the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: a metal pipe reducing joint, comprising a reducing joint body, both sides of the reducing joint body are provided with sealing gaskets, two metal pipe bodies of different diameters are provided on both sides of the reducing joint body, an annular connecting plate is fixedly installed on the outside of the metal pipe body, and a plurality of slots are opened on one side of the annular connecting plate;

[0006] Two guide plates are installed on the outside of the reducer joint body, and two movable plates are slidably installed on the reducer joint body and the outside of the two guide plates. A U-shaped rotating rod that can pass through the card slot is hinged on one side of the movable plate, and an adjustment component for driving the two movable plates to move simultaneously is arranged on the surface of the guide plate on one side.

[0007] Preferably, the sealing gasket is made of rubber.

[0008] Preferably, the outer diameters of the two annular connecting plates are the same.

[0009] Preferably, the number of the U-shaped rotating rods is consistent with the number of the slots, and the positions of the U-shaped rotating rods correspond to the opening positions of the slots.

[0010] Preferably, the adjustment assembly comprises a threaded rod, the outer side of the threaded rod is threadedly connected to a lifting plate, both sides of the lifting plate are hinged with support plates, and one end of the support plate away from the lifting plate is hinged to one side of the moving plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the metal pipe reducer is inserted into the metal pipe body, the groove on the surface of the annular connecting plate corresponds to the position of the U-shaped rotating rod on the side of the moving plate. Then, the threaded rod drives the lifting plate to rise by rotation, so that the lifting plate drives the supporting plate to move, and the supporting plate drives the U-shaped rotating rod to move through the moving plate. After the U-shaped rotating rod enters the groove first, the U-shaped rotating rod contacts the inner wall of the groove, thereby pulling the two annular connecting plates to move in the direction close to the moving plate. The annular connecting plate drives the two metal pipe bodies to move closer to each other, so that the metal pipe bodies squeeze the sealing gasket and finally complete the docking sealing work. It is simple to operate, has high connection efficiency, and can ensure the sealing after connection.

[0013] 2. The metal pipe reducer can be used to control the two movable plates to approach each other by rotating the threaded rod during use, and drive the U-shaped rotating rod and the annular connecting plates on both sides to move in the direction of approaching each other, so that the two metal pipe bodies can be docked synchronously, and its efficiency is relatively high. When the metal pipe needs to be removed, the movable plate is controlled to move to drive the U-shaped rotating rod out of the slot, and then the U-shaped rotating rod can be rotated to a position where it does not block the annular connecting plate and the slot, and the metal pipe body can be taken out.

[0020] Two guide plates 4 are installed on the outside of the reducer body 1, and two movable plates 5 are slidably installed on the outside of the reducer body 1 and the two guide plates 4. A U-shaped rotating rod 6 that can pass through the slot 8 is hinged on one side of the movable plate 5, and an adjustment component for driving the two movable plates 5 to move simultaneously is arranged on the surface of one side guide plate 4.

[0021] Specifically, the adjustment component drives the two movable plates 5 to move, thereby driving the U-shaped rotating rod 6 to move. The U-shaped rotating rod 6 can drive the metal pipe body 3 to move through the annular connecting plate 7, and finally be fixed in the reducing joint body 1, thereby synchronously completing the docking work of the two metal pipe bodies 3.

[0022] Wherein: the sealing gasket 2 is made of rubber material, and the metal pipe body 3 squeezes the sealing gasket 2, thereby ensuring the sealing of the joint.

[0023] The number of U-shaped rotating rods 6 is consistent with the number of slots 8 , and the positions of the U-shaped rotating rods 6 correspond to the opening positions of the slots 8 , so that the U-shaped rotating rods 6 can be inserted into the slots 8 to pull the annular connecting plate 7 to move.

[0024] Wherein: the adjustment component includes a threaded rod 10, the outer side of the threaded rod 10 is threadedly connected to a lifting plate 11, both sides of the lifting plate 11 are hinged with support plates 9, and one end of the support plate 9 away from the lifting plate 11 is hinged to one side of the moving plate 5.
