Description

Technical Field

[0001] This utility model belongs to the field of assembly technology, specifically, it relates to a pipe connection assembly. Background Technology

[0002] In the manufacturing and assembly of components, due to the accumulation of manufacturing and assembly errors, it is often necessary to use a slotted hole connection on the connectors to provide sufficient assembly allowance while ensuring connection stability. The traditional solution involves placing a slotted hole in one direction on one connector and a slotted hole perpendicular to it on another connector, forming a cross-shaped hole structure after assembly. While this design can meet assembly adjustment requirements, it still has the following significant drawbacks:

[0003] Poor versatility of connectors: When one of the connectors needs to be rotated due to installation requirements, the direction of the waist hole needs to be readjusted, which makes the connector unable to be directly reused, increasing design and manufacturing costs. Utility Model Content

The plurality of first elongated holes are arranged in a circumferentially and are deflected in sequence, and the deflection angle between any two adjacent first elongated holes is equal to the central angle.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] A first exemplary embodiment of this utility model provides a pipe connection assembly, as shown in the attached drawing. Figure 1 To be continued Figure 5 As shown, the pipe connection assembly includes:

[0040] The first connector 1 has a first mating surface 1a, on which a plurality of annularly distributed first elongated holes are formed. The plurality of first elongated holes are arranged in a circumferentially and are deflected in sequence, and the deflection angle between any two adjacent first elongated holes is equal to the central angle.

[0041] The second connector 2 has a second mating surface 2a, on which a plurality of annularly distributed second elongated holes are formed. The plurality of second elongated holes are arranged in a circumferentially and deflected in sequence, and the deflection angle between any two adjacent second elongated holes is equal to the central angle.

[0042] The first mating surface 1a and the second mating surface 2a are mated together. Multiple first elongated holes and multiple second elongated holes are aligned one-to-one and arranged in a cross shape. The aligned first elongated holes and second elongated holes are connected to each other by fasteners.

[0043] In the pipe connection assembly of this exemplary embodiment, the first mating surface 1a of the first connector 1 has a plurality of first elongated holes arranged sequentially around the circumference, and the deflection angle between any two adjacent first elongated holes is equal to the central angle. The second mating surface 2a of the second connector 2 has a plurality of annularly distributed second elongated holes arranged sequentially around the circumference, and the deflection angle between any two adjacent second elongated holes is equal to the central angle. The first mating surface 1a and the second mating surface 2a are mated together, and the plurality of first elongated holes and the plurality of second elongated holes are connected. The holes are aligned one-to-one and arranged in a cross shape. With this configuration, when the first connector 1 or the second connector 2 rotates due to installation requirements, the first connector 1 or the second connector 2 can rotate after the fasteners are removed. The rotation angle is the central angle between any two adjacent elongated holes or a multiple of that central angle. After rotating to the correct position, the multiple first elongated holes and multiple second elongated holes will still be aligned one-to-one and arranged in a cross shape. There is no need to redesign and adjust the elongated holes of the entire pipe connection assembly. In this way, the versatility of the pipe connection assembly is improved and the design and manufacturing costs are reduced.

[0044] In practical applications, the number of first elongated holes on the first mating surface 1a and the number of second elongated holes on the second mating surface 2a can be selected according to actual needs and application scenarios. For example, the number of first and second elongated holes can each be set to 4, in which case the deflection angle and central angle between any two adjacent first elongated holes are both 90°, and the deflection angle and central angle between any two adjacent second elongated holes are both 90°. Alternatively, the number of first and second elongated holes can each be set to 8, in which case the deflection angle and central angle between any two adjacent first elongated holes are both 45°, and the deflection angle and central angle between any two adjacent second elongated holes are both 45°. Yet another example is that the number of first and second elongated holes can each be set to 16, in which case the deflection angle and central angle between any two adjacent first elongated holes are both 22.5°, and the deflection angle and central angle between any two adjacent second elongated holes are both 22.5°. In other words, theoretically, the number of first and second elongated holes can be chosen to be 2... nIf there are two adjacent first elongated holes, then the deflection angle and the central angle between them are both 90° / 2. （n-2） The deflection angle and central angle between any two adjacent second elongated holes are both 90° / 2. （n-2） .

[0045] In one alternative embodiment, both the first elongated hole and the second elongated hole are oblong holes.

[0046] Of course, in some other embodiments, the first elongated hole and the second elongated hole can also be square holes.

[0047] In an alternative embodiment, refer to the appendix Figure 1 To be continued Figure 5 As shown, the first connector 1 includes a first mounting part 11 and a first plate-shaped connecting part 12.

[0048] The second connector 2 includes a second mounting portion 21 and a second plate-shaped connecting portion 22. One side of the second plate-shaped connecting portion 22 is a second mating surface 2a, and the second mounting portion 21 is connected to the other side of the second plate-shaped connecting portion 22.

[0049] In practical applications, the first plate-shaped connecting part 12 and the second plate-shaped connecting part 22 are connected to each other through the mating of the first mating surface 1a and the second mating surface 2a. The first mounting part 11 and the second mounting part 21 are used to connect and install the required assembly parts, thereby realizing the assembly connection between the required assembly parts.

[0050] Of course, in other embodiments, the first connector 1 and the second connector 2 may also have other structural forms. For example, the first connector 1 may only include the first plate-shaped connecting part 12, and the second connector 2 may only include the second plate-shaped connecting part 22. The first plate-shaped connecting part 12 and the second plate-shaped connecting part 22 are directly connected to the required assembly parts.

With this configuration, during the process of the first mating surface 1a and the second mating surface 2a mating with each other, it is only necessary to align the square edges of the first plate-shaped connecting part 12 and the second plate-shaped connecting part 22 with each other to achieve one-to-one alignment and cross-shaped arrangement of multiple first elongated holes and multiple second elongated holes. The first connecting member 1 and the second connecting member 2 can be rotated as needed. In this way, the mating efficiency can be significantly improved, thereby improving the assembly efficiency. In addition, it can reliably ensure that the multiple first elongated holes and multiple second elongated holes are one-to-one aligned and cross-shaped, thereby ensuring the assembly accuracy and effectively avoiding the problem that the inability to form a stable connection due to incorrect hole orientation during the assembly process, which would affect product quality.

[0056] In an alternative embodiment, refer to the appendix Figure 1 As shown, both the first mounting part 11 and the second mounting part 21 are columnar structures. The first mounting part 11 is coaxially arranged with the first plate-shaped connecting part 12, and the second mounting part 21 is coaxially arranged with the second plate-shaped connecting part 22. With this arrangement, the required assembly components can be respectively fitted onto the first mounting part 11 and the second mounting part 21, thereby achieving coaxial assembly.
