Description

A movable nut connection fixing device

technical field

The utility model relates to a fastening device, in particular to a movable nut connection and fixing device.

Background technique

The movable nut is widely used in the field of pipeline connection because of its convenient connection and the ability to adjust the azimuth angle of the connected parts. Although the traditional movable nut can clamp the connecting pipe and the joint tightly, the sealing effect is good without vibration and shock, but when there is vibration or shock, there may be relative rotation between the movable nut and the connecting pipe, so that the sealing The gasket is worn or deformed, which will adversely affect the sealing performance and reliability of the connection. At present, in the field of pipeline connection, there are very limited methods for loosening or fixing movable nuts, and there is no practical and reliable solution in this regard.

Contents of the invention

The utility model proposes a movable nut connection and fixing device, which can be fixed with the connecting pipe after the movable nut is tightened, thereby improving the sealing performance and reliability of the connection.

In order to solve the above technical problems, the utility model provides a movable nut connection and fixing device, which is characterized in that it includes a joint, a gasket, a movable nut, a connecting pipe, a stop washer and a lock nut; the movable nut, the stop washer and The locking nut is set on the connecting pipe; the joint and the connecting pipe are sealed by a gasket and pressed by the movable nut; the locking nut cooperates with the thread provided on the connecting pipe to compress the stop washer.

Further, the movable nut and the stop washer are provided with several engaged teeth and grooves.

Further, the protruding teeth and grooves provided on the movable nut and the stop washer are distributed along the circumferential direction.

Further, the protruding teeth or grooves are uniformly distributed at intervals of 15°.

Further, a waist-shaped rod is provided on the connecting pipe, and a waist-shaped hole matched with the waist-shaped rod is provided on the stop washer.

Compared with the prior art, the utility model has the remarkable advantages: (1) the installation and disassembly of the movable nut is convenient and fast; (2) after the locking nut presses the stop washer, the azimuth angle of the connected joint and the connecting pipe can be effectively controlled , and will not loosen, and the whole structure is stable and reliable; (3) Compared with the traditional movable nut connection, the utility model has obtained greater improvement in function and reliability with less cost.

detailed description

It is easy to understand that, according to the technical solution of the utility model, those skilled in the art can imagine various implementations of the movable nut connection and fixing device of the utility model without changing the essence of the utility model. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the entirety of the utility model or as a limitation or limitation on the technical solution of the utility model.

Example

1 and 2 , the movable nut connection and fixing device includes a joint 1 , a gasket 2 , a movable nut 3 , a connecting pipe 4 , a stop washer 5 and a locking nut 6 .

The joint 1 and the connecting pipe 4 are sealed by the gasket 2 and pressed by the movable nut 3. The lock nut 6 is used to compress the stop washer 5, thereby fixing the movable nut 3 and limiting it.

3 and 4, twelve protruding teeth and grooves 8 are evenly distributed on the back of the movable nut 3 at intervals of 15° along the circumferential direction;

5 and 6, a total of twelve protruding teeth and grooves 9 are evenly distributed along the circumference of the stop washer 5 at intervals of 15°, and the movable nut 3 and the brake washer 5 are engaged and assembled so that the movable nut 3 and the stop The degree of freedom of the washer 5 to rotate in the axial direction is consistent.

As shown in Figure 5, a waist-shaped hole 10 is opened on the stop washer 5; 7, so that the degree of freedom of rotation of the stop washer 5 and the adapter 4 in the axial direction is consistent.

The locking nut 6 cooperates with the screw thread on the connecting pipe 4 to press the stop washer 5 to limit the freedom of displacement of the locking nut 6 in the axial direction.

After the installation of the entire fixing device is completed, as long as the lock nut 6 presses the stop washer 5, the degrees of freedom of the movable nut 3, the stop washer 5, and the connecting pipe 4 in the axial direction are always consistent, thereby realizing the fixation of the movable nut 3 .
