Description

Technical Field

[0001] This utility model relates to the field of pipe fitting threading technology, and in particular to a pipe fitting threading device. Background Technology

[0002] Currently, many construction fields such as building, construction, and maintenance require the installation of a lot of pipes. There are many ways to install pipes. For example, the connection method of pipes for HVAC, fire protection, water supply and drainage is mostly threaded connection. Therefore, it is necessary to use a threading machine to thread the purchased pipes, and then use pipe fittings to connect with the external thread to achieve the purpose of pipe connection.

[0003] When threading pipes for fire protection, water supply and drainage, etc., it is found that threading short pipes is easier, the quality is higher, and they are easier to use. However, threading longer pipes is more difficult because the pipes are long, requiring multiple people to lift and thread them. Even using this method, the external threads are often of poor quality due to unevenness in the pipe, resulting in many defective products that are often unusable, causing a lot of waste. At the same time, using this method wastes a lot of manpower, and if the threaded external thread is not up to standard, it will also waste pipe materials, resulting in waste. Utility Model Content

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, the pipe threading processing device provided by this utility model includes: a base 1, a lifting support column, and a V-shaped support frame.

[0039] The base 1 may include a first channel steel member perpendicularly connected to the lifting support column. To increase stability, the base 1 may also include a second channel steel member perpendicularly connected to the lifting support column, with the bottom surfaces of the first and second channel steel members on the same plane. The first and second channel steel members can be arranged at a 90° angle and welded into a cross shape, making the base 1 more stable and suitable for mounting large-diameter pipes.

[0040] The length of the lifting support column is adjustable, allowing for adjustment of the distance between its bottom and top ends. The bottom end of the lifting support column is connected to the base 1. Specifically, the lifting support column includes a tube 2 and a column 3. The tube 2 has internal threads. The lower cylindrical portion of the column 3 has external threads that connect with the internal threads. By rotating the column 3, its height can be changed. The upper portion of the column 3 (the part exposed outside the tube 2) has a quadrilateral cross-section. The sides of the upper portion are flat for easy connection to a V-shaped support frame.

[0041] The V-shaped support frame includes two support arms 6 arranged at an angle. In this embodiment, the two support arms 6 are symmetrically welded to opposite sides of the upper part of the column 3. From bottom to top, the included angle between the two support arms 6 gradually increases, forming a V-shape to provide stable support for the pipe. Rolling elements are rotatably connected to the surfaces of the two support arms 6 facing each other. The rolling elements may include bearings 4. The axial direction of the rolling elements is perpendicular to the plane where the two support arms 6 are located. During the threading process of the pipe, the outer wall of the pipe undergoes rolling friction with the rolling elements, resulting in less friction.

[0042] The support arm 6 may include a first plate and a second plate spaced apart. The ends of the first plate and the second plate may be connected to the upper part of the column 3. The bearing 4 and the rotating shaft 5 are both located between the first plate and the second plate. The rotating shaft 5 may be fixedly connected to the first plate and the second plate, and the bearing 4 may be rotatably connected to the rotating shaft 5. The main function of the bearing 4 is to ensure that the pipe can rotate with the rotation of the threading machine when the pipe is threaded.

[0043] Example 2

[0044] like Figure 3 and Figure 4As shown, the difference from Embodiment 1 is that in Embodiment 1, the support arm 6 is welded to the upper part of the main body. However, in this embodiment, to reduce the overall volume of the device when stored, the support arm 6 is rotatably connected to the lifting support column, and a locking structure is provided between the support arm 6 and the lifting support column. This allows the V-shaped support frame to be in both a working and a stored state. In the working state, the two support arms 6 are set at an angle, and in the stored state, the support arms 6 are parallel to the lifting support column. In other words, when the device is not in use, the two angled support arms 6 can be rotated to a parallel state to reduce its space occupation.

[0045] Specifically, a locking pin 7 is inserted into the support arm 6, and the locking pin 7 can slide relative to the support arm 6. The lifting support column is provided with a first locking hole 8 and a second locking hole 9, both located on the swing path of the locking pin 7. When the locking pin 7 is connected to the first locking hole 8, the support arm 6 is locked in the working state, such as... Figure 3 As shown. When the locking pin 7 is connected to the second locking hole 9, the support arm 6 is locked in the retracted state, as shown. Figure 4 As shown.

[0046] To further reduce the storage volume, the base 1 is threadedly connected to the lifting support column, meaning that in the storage state, the base 1 and the lifting support column can be separated and stored separately.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
