Abstract

This creation is a structural improvement of a pipe joint. The two ends of the pipe joint are hexagon head and external thread with internal thread respectively. The internal hole of the external thread has a special-shaped hole structure corresponding to the shape of the tool, so that it can be used in the pipe joint. Corresponding to the screw connection of the wall pipeline, in addition to locking and fixing through the hexagonal head, it can also be locked and fixed through the special-shaped hole when the pipeline is recessed in the wall, so as to prevent the pipe joint from being unable to completely screw the pipeline and fix it, or because of the tool Rotate and damage the wall.

Description

Pipe joint structure improvement

The invention relates to a structural improvement of a pipe joint, in particular to a special-shaped hole in which the inner hole of the external thread end of the pipe joint is a corresponding tool shape.

The pipe joint is a joint structure for pipeline connection. In addition to being available for quick installation, it also has the functions of extending the size and combining with different diameters.

In the pipeline construction of general buildings, the pipelines of the water pipes must be buried in the concrete in advance for the purpose of protection and beauty, and only the pipe ends of the pipelines are exposed to the wall surface of the wall for construction and installation of faucets or other water outlets. However, due to the influence of construction quality and concrete solidification or whether the walls are laid with tiles in the future, the pipe ends of the pipes often appear concave in the wall surface, so the pipe ends of the pipes must be screwed to the pipe joints Re-supply faucets or other water outlets are installed. The purpose is not only to make the pipe end concave in the wall to obtain a convex extension, but also to replace the faucet or other water outlets in the future. The inner thread of the pipe end is damaged (if the inner thread of the pipe end is damaged, it will cause water leakage. Once the pipe is replaced or repaired, the concrete wall there must be smashed, and the construction cost is extremely high). However, because the conventional pipe joint only has a hexagonal head on the outside of the outwardly facing internal thread for the tool to apply force to lock and fix, it is inevitable that the tool will contact the wall during the process of applying force to lock and cause wear and tear, and the hexagonal head of the pipe joint is in In the process of locking, once it goes deep into the wall, it cannot apply force Therefore, in common use, the water-stop effect is achieved by increasing the winding thickness of the water-stop belt, which is inconvenient in construction and the risk of water leakage.

In view of the above-mentioned problems, the author of this paper deeply feels that the design of the commonly used pipe joints is only to provide the function of connecting pipes, and lacks practical considerations for various situations faced during construction. Therefore, he has been engaged in water pipe structure design for many years Manufacturing experience, active R&D and improvement, and careful consideration of the conditions of all parties, finally created the design of this structure, which will completely solve the various deficiencies in common use.

This creation is a structural improvement of a pipe joint. The two ends of the pipe joint are hexagon head and external thread with internal thread respectively, and the internal hole of the external thread has a special-shaped hole structure corresponding to the shape of the tool. Therefore, after implementation, the Can provide the following performance:

Because the pipe joint of this creation is tied to the inner hole of the external thread and has a special-shaped hole structure corresponding to the shape of the tool (the special-shaped hole is, for example, a hexagonal hole or a twelve-corner hole, which can be rotated by a hexagonal wrench), so when the pipe joint corresponds to When screwing the exposed pipe end of the wall pipeline, in addition to the traditional method of locking and fixing it through the hexagonal head, it can also be done by extending the tool into the special-shaped hole and applying force to rotate the pipe joint when the pipeline is too inside the concave wall. Locking and fixing, not only can avoid the wear and tear between the tool and the wall due to contact, but also can completely lock the outer thread of the winding waterstop into the pipe end of the pipeline, and promote the combination of the pipe joint and the pipeline more It is stable, so it can be more convenient to assemble the water supply tap or other water outlet.

In order to enable your examiners to clearly understand the structural composition of this creation and the functional benefits it can achieve, for the rest, the embodiments are listed in conjunction with the drawings, and the detailed description is as follows: This creation is a structural improvement of pipe joints. The two ends of the joint 1 are hexagonal heads 11 and external threads 13 with internal threads 12 respectively, wherein the inner hole 14 of the external thread 13 has a special-shaped hole 15 structure corresponding to the shape of the tool (as shown in Figures 1, 2, and 3) , so that when the pipe joint 1 corresponds to the pipeline 3 in the wall 2 for screw connection, in addition to being locked and fixed by applying force through the hexagonal head 11, it can also be carried out through the special-shaped hole 15 when the pipeline 3 is recessed in the wall 2 Lock and fix to avoid that the pipe joint 1 cannot be completely screwed to the pipeline 3 and fixed, or the wall 2 is damaged due to the rotation of the tool.

From the structural design of the above-mentioned invention, it can be seen that because the pipe joint 1 of the invention is provided with a special-shaped hole 15 structure corresponding to the shape of the tool in the inner hole 14 of the external thread 13 (the special-shaped hole 15 can be, for example, a hexagonal hole, a twelve-point hole, etc.) Corner hole... etc., can be extended by a hexagonal wrench or other shaped wrench to apply force to rotate), so when the pipe joint 1 is screwed to the pipe end of the pipe 3 exposed on the wall 2 (as shown in Figure 4 As shown), in addition to applying force and locking through the hexagonal head 11 in the traditional way, when the pipeline 3 is too inside the concave wall 2, the end of the internal thread 12 can be inserted into the special-shaped hole 15 through a tool to apply force to rotate the pipe joint 1 is locked and fixed, so it can not only avoid the wear and tear between the tool and the wall 2 due to force and contact, but also make the outer surface of the winding waterstop The thread 13 is completely locked into the pipe end of the pipeline 3, so that the combination of the pipe joint 1 and the pipeline 3 is more stable, so it is more convenient to assemble the water supply faucet 4 or other water outlets (as shown in Figure 5), and in the It is convenient for maintenance and replacement in the future.
