Description

Pipe connection structure

The invention relates to a pipe connection structure, which comprises a first pipe with a connection end. The connection end of the first pipe has a groove, so that a second pipe can be sleeved thereon at a larger installation angle.

In the installation operation of connecting two pipes, it is sometimes necessary to first install the first pipe in position and then connect the second pipe to the first pipe. Due to the shape of the connecting end of the known pipe, the butt installation of the first pipe and the second pipe must be carried out on the same central axis, or the central axis of the second pipe is only allowed to be slightly inclined relative to the central axis of the first pipe at a relatively small angle. In other words, the range of the installation angle of the second pipe to the first pipe is quite limited. Due to the limitations of the installation environment, the existing narrow space can only allow the second pipe to be connected to the first pipe at a larger installation angle, but the connecting end of the first pipe cannot allow such a larger installation angle installation method. The above-mentioned problem of the two pipes being difficult to connect in a limited space needs to be improved urgently. Therefore, the inventor of this case improved the known pipe connection structure to overcome the shortcomings of the previous technology.

One purpose of the present invention is to provide a pipe connection structure, which utilizes a groove at the connection end of a first pipe so that when a second pipe is installed on the first pipe, a larger range of installation angles can be achieved, and a better guiding effect can be provided, thereby improving the installation workability of the connection between the two pipes. Therefore, the present invention provides a pipe connection structure, which basically includes a first pipe. The first pipe has a connection end for the second pipe to be sleeved thereon. The connection end of the first pipe has a groove, and the reference surface defined by the edge of the groove is inclined relative to the central longitudinal axis of the first pipe. Preferably, the connection end has a hook portion. Preferably, during the initial installation of the second pipe member at a mounting angle to the connecting end of the first pipe member, the central longitudinal axis of the second pipe member can be tilted relative to the central longitudinal axis of the first pipe member. Preferably, the second pipe member allows the second pipe member to be tilted relative to the first pipe member at the mounting angle by the slot of the first pipe member. Preferably, in the case where the first pipe member is arranged at a configuration plane, the slot is located on a side of the first pipe member adjacent to the configuration plane. Preferably, the slot is V-shaped. Preferably, the slot is arc-shaped. Preferably, the slot is parabolic. The advantages of this novel technology over the prior art are as described in the above-mentioned purposes, and those familiar with this technology can better understand the other advantages and purposes of the novel technology defined in each claim after reading the disclosure of this application.

The other technical contents, features and effects of the present invention mentioned above will be clearly understood in the detailed description of the preferred embodiment with reference to the following drawings. The pipe connection structure of the present invention is shown as a connection for pipes of air conditioners, especially for connecting two pipes at a larger installation angle in a narrow space. When the drain elbow of the air conditioner is installed close to the bracket, although limited by the space of the bracket, the drain pipe can be installed at a larger installation angle on the drain elbow with a groove such as the present invention, without the need to axially align the two pipes during the initial installation, and the initial installation of the two pipes in the narrow space often does not allow or is not conducive to axially aligning the two pipes. At the same time, the oblique groove of the drain elbow has the effect of guiding the drain pipe to be installed, so as to facilitate the drainage pipe to be aligned with the drain elbow. It should be understood that the connection between the drain elbow and the drain pipe of the air conditioner described below can also be regarded as a connection between other types of pipes or joints. That is to say, the pipe connection structure described herein is not limited to the specific application of air conditioner pipes, but can be widely used in the connection of various pipes or joints. As shown in Figures 1 to 3, the pipe connection structure of the present invention basically includes a first pipe 10. The first pipe 10 has a connection end 11 for the second pipe 20 to be sleeved thereon. The first pipe 10 also has an equipment end 15 for connecting to an equipment. The connection end 11 of the first pipe 10 has a groove 12. The connecting end 11 of the first pipe 10 also has a hook portion 13 to be securely sleeved thereon with the second pipe 20. However, the hook portion 13 of the first pipe 10 can be omitted from this embodiment as long as the first pipe 10 can be connected to the second pipe 20 in various other connection methods in the art. The edge 12e of the groove 12 of the first pipe 10 defines a reference surface, and this reference surface is inclined relative to the central longitudinal axis A1 of the first pipe 10. In this embodiment, the groove 12 is V-shaped. However, the shape of the groove 12 is not limited to the V-shape shown in FIG. 1, but in other cases it can be an arc or other suitable shape (not shown), such as a parabola. In other cases, the groove 12 can be set at both ends of a pipe in addition to being set at one end of a pipe. In the present invention, the material of the pipe fitting can be plastic, metal or other suitable pipe fitting materials. The groove of the pipe fitting can be formed by molding. In other cases, the groove of the pipe fitting can be formed by cutting or other mechanical processing of the connecting end of the pipe fitting. Now referring to Figure 3, during the initial installation of the second pipe fitting 20 at the connecting end 11 of the first pipe fitting 10 at an installation angle, the central longitudinal axis A2 of the second pipe fitting 20 can be inclined relative to the central longitudinal axis A1 of the first pipe fitting 10. When the first pipe fitting 10 is set at the configuration plane 30, the groove 12 is located on the side of the first pipe fitting 10 adjacent to the configuration plane 30. In this way, the second pipe 20 is allowed to tilt relative to the first pipe 10 at the installation angle by the groove 12 of the connecting end 11 of the first pipe 10, avoiding the end interference caused by the tilt of the second pipe 20 relative to the first pipe 10. Such a structure provides a larger installation angle for the second pipe 20, and can further guide the second pipe 20 to align with the first pipe 10. Using the pipe connection structure of the present invention as shown in Figure 3, during the initial installation of the pipe connection structure of the present invention, the first pipe 10 is adjacent to the configuration plane 30. By setting the groove 12, a larger installation angle α between the central longitudinal axis A1 of the first pipe 10 and the central longitudinal axis A2 of the second pipe 20 can be provided. In contrast, FIG. 4 shows a known pipe connection structure, which includes a first pipe 100 without a groove for sleeve connection with a second pipe 200. During the initial installation of the known pipe connection structure, the first pipe 100 is adjacent to the configuration plane 300, which can provide a smaller installation angle β between the central longitudinal axis A11 of the first pipe 100 and the central longitudinal axis A21 of the second pipe 200. Obviously, the present invention provides an improved connection structure compared to the known pipe connection structure, which has a larger range of installation angles and a guiding effect, so as to facilitate the sleeve installation of two pipes, especially greatly improving the installation workability in a small space. Although only selected embodiments are used to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various simple equivalent changes or modifications can be implemented, which should fall within the scope of the present invention. All features or advantages do not necessarily need to be presented simultaneously in a particular embodiment. Therefore, the contents of the above embodiments are for illustrative purposes only, and are not intended to limit the present invention as defined by the scope of the patent application and its equivalents.
