Description

Technical Field

[0001] This utility model relates to the technical field of connecting metal rigid pipes and metal pipe joints in vehicle piping systems such as automotive active damping suspension hydraulic piping systems, chassis hydraulic oil piping systems, air conditioning piping systems, battery liquid cooling piping systems, and motor oil cooling piping systems, and particularly to a metal right-angle pipe joint for metal rigid pipes. Background Technology

[0002] The internal flow channel of a conventional right-angle connector is machined using a tapered drill bit; see [link / reference]. Figure 1 The intersection lines of the two holes (i.e., the first inner hole and the second inner hole in a perpendicular state) are complex and difficult to remove burrs. The complex shape of the flow channel leads to severe turbulence, low fluid flow velocity, and high flow resistance, which affects the performance of the fluid hydraulic system.

[0003] Therefore, how to improve the internal shape of the flow channel in the right-angle joint to facilitate efficient removal of burrs at the intersection line, increase fluid flow velocity, and reduce flow resistance has become a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a metal right-angle pipe connector for metal rigid pipes, mainly to solve the problems of how to improve the internal shape of the flow channel of the right-angle connector, facilitate efficient removal of burrs at the intersection line, increase fluid flow velocity, and reduce flow resistance in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a metal right-angle pipe connector for metal rigid pipes, including a first inner hole and a second inner hole, the first inner hole and the second inner hole being perpendicular, characterized in that: the diameters of the first inner hole and the second inner hole are different, and a closed, smooth transition intersection line is formed at the intersection of the first inner hole and the second inner hole.

[0006] Furthermore, the diameter difference between the first inner hole and the second inner hole is equal to or greater than 0.5 mm.

[0007] Furthermore, a conical recess is provided at the bottom of the first inner hole or the bottom of the second inner hole.

[0008] In view of the above technical features, the present invention has the following beneficial effects:

[0009] 1. This utility model discloses a metal right-angle pipe joint for metal rigid pipes, wherein the diameters of the two intersecting first inner holes and the second inner hole are different, for example, the diameter of the first inner hole is slightly smaller than the diameter of the second inner hole. In this way, a complete and smooth intersection line can be formed at the intersection of the first inner hole and the second inner hole. The intersection line is very easy to deburr, the processing cost is low, and the shape of the intersection line is regular. The internal shape of the internal flow channel formed by the first inner hole and the second inner hole is simple, which can reduce fluid resistance, increase the fluid flow velocity in the metal right-angle pipe joint, and avoid affecting the performance of the fluid hydraulic system.

[0015] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0016] See Figures 2 to 3 Specific embodiment 1: This embodiment 1 provides a metal right-angle pipe connector for metal rigid pipes, including a first inner hole 2 and a second inner hole 3. The first inner hole 2 and the second inner hole 3 are perpendicular to each other. The diameters of the first inner hole 2 and the second inner hole 3 are different. A closed and smooth transition intersection line 4 is formed at the intersection of the first inner hole 2 and the second inner hole 3.

[0017] Preferably, the diameter difference between the first inner hole 2 and the second inner hole 3 is equal to or greater than 0.5 mm.

[0018] The diameters of the two intersecting inner holes 2 and 3 are different; for example, the diameter of the first inner hole 2 is slightly smaller than that of the second inner hole 3 (e.g., the difference in diameter between the first inner hole 2 and the second inner hole 3 is 0.5 mm). This allows for the formation of a complete and smooth intersection line 4 at the intersection of the first inner hole 2 and the second inner hole 3. The intersection line 4 is very easy to deburr, resulting in low processing costs. Furthermore, the regular shape of the intersection line 4 and the simple internal shape of the flow channel formed by the first inner hole 2 and the second inner hole 3 reduce fluid resistance and increase the fluid flow velocity within the metal right-angle pipe joint 1, thus avoiding any impact on the performance of the fluid hydraulic system. See also... Figure 3 In this embodiment 1, a metal right-angle pipe connector 1 for a metal rigid pipe is used to connect to a metal rigid pipe 7.

[0019] See Figures 2 to 3 In specific embodiment 2, this embodiment 2 provides a metal right-angle pipe joint for metal rigid pipes. The difference between this embodiment 2 and embodiment 1 is that a conical concave portion 5 is provided at the bottom of the first inner hole 2 or the bottom of the second inner hole 3. When the first inner hole 2 and the second inner hole 3 are processed by two conical cutting tools of different diameters (such as conical drill bits), in order to form a complete and smooth intersection line 4 at the intersection of the first inner hole 2 and the second inner hole 3, the conical cutting tool in the later processing (such as processing the second inner hole 3 with a larger diameter later) should penetrate the inner hole processed first (such as processing the first inner hole 2 with a smaller diameter first) and leave a conical concave portion 5 on the side wall of the pipe joint. This processing method is simpler and more efficient.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
