Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, specifically to a movable pipe fitting. Background Technology

[0002] Hose, such as stainless steel braided hose, has limited bending performance. For equipment such as toilets or washbasins, due to the limited installation space, if one end of the hose is directly connected to the equipment and the other end is connected to the angle valve on the wall during installation, the hose will be stretched, bent, or even deformed during the installation process. This will reduce the water flow cross-section of the hose, affect the water output, and ultimately affect the performance of the equipment. Utility Model Content

[0006] The first tube and the second tube are connected end to end and integrally formed. The central axes of the first tube and the second tube are arranged at a certain angle, and the angle is between 90° and 180°.

[0007] Furthermore, the upper end of the first tube passes through the connecting cover and is engaged by a scissor spring.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Reference Figures 1 to 4As shown, a movable pipe fitting includes a connecting cap 1 and a movable pipe 2. The movable pipe 2 is a rigid pipe and includes a first pipe section 21 and a second pipe section 22. The first pipe section 21 is rotatably connected to the connecting cap 1. A plurality of sealing rings 3 are provided between the first pipe section 21 and the connecting cap 1. The first pipe section 21 and the second pipe section 22 are not arranged in parallel. The connecting cap 1 is provided with a first thread 111, and the second pipe section 22 is provided with a second thread 221. It is connected to the device A through the first thread 111 and to the hose 6 through the second thread 221. This can avoid pulling, bending, or even deformation of the hose 6 during installation, thus avoiding affecting the water flow of the hose.

[0022] During assembly, the connecting cover 1 is connected to the device A via the first thread 111. The movable tube 2 can be rotated 360° to any angle. By rotating the movable tube 2 to a suitable angle, it is then connected to the hose 6 via the second thread 221 of the movable tube 2. The sealing ring 3 prevents water leakage at the connection between the connecting cover 1 and the movable tube 2.

[0023] Because the movable pipe 2 is a rigid pipe, and the first pipe section 21 and the second pipe section 22 are not arranged in parallel, the installation process can avoid pulling, bending, or even deformation of the flexible hose 6, thus preventing any impact on the water flow. Furthermore, in the long run, this helps prevent internal deformation of the flexible hose 6 from creating wrinkles or blockages that obstruct water flow, thereby ensuring a stable and sufficient water output. This meets the water volume requirements of various water usage scenarios, guarantees the normal water supply function of related equipment A or the system, and reduces maintenance and replacement costs caused by problems with the flexible hose 6.

[0024] The movable tube 2 shell is made of metal or plastic, thus forming a rigid tube. The sealing ring 3 is fitted around the outer periphery of the first tube 21 and abuts against the connecting cover 1.

[0025] In order to facilitate the processing and forming of the movable tube 2 and to save material usage, the first tube section 21 and the second tube section 22 are connected end to end and integrally formed.

[0026] To facilitate connection to the hose 6 via the external thread of the second tube 22 in confined spaces, refer to... Figure 3 As shown by the midpoint angle R, the central axes of the first tube section 21 and the second tube section 22 are arranged at a certain angle, which is between 90° and 180°. Preferably, the angle between the central axes of the first tube section 21 and the second tube section 22 is between 115° and 175°.

[0027] To ensure a secure connection between the connecting cover 1 and the movable tube 2, the upper end of the first tube 21 passes through the connecting cover 1 and is secured by a shaft retaining spring 4.

[0028] To further ensure the secure connection between the connecting cover 1 and the movable tube 2, and to position the connecting cover 1, the movable tube 2 includes a stepped portion 23, and the lower end of the connecting cover 1 abuts against the stepped portion 23.

[0029] The connecting cover 1 is provided with an annular groove 13, and the first thread 111 is provided on the inner circumferential surface of the annular groove 13. Specifically, the connecting cover 1 includes a first annular portion 11 and a second annular portion 12 arranged coaxially and at intervals. The interval between the first annular portion 11 and the second annular portion 12 forms the annular groove 13. The first tube portion 21 passes through the second annular portion 12, and the first thread 111 is provided on the inner wall of the first annular portion 11, thereby facilitating the assembly of the connecting cover 1 with the device A and the movable tube 2 respectively.

[0030] The outer peripheral surface of the connecting cover 1 has parallel and symmetrically arranged planes. Preferably, the outer peripheral surface of the connecting cover 1 is a hexagonal structure. With the above arrangement, it is easy to tighten the connecting cover 1 to the device A with a wrench.

[0031] The bottom of the annular groove 13 is provided with a sealing gasket 5. The bottom of the pipe of the device A abuts against the sealing gasket 5, thereby preventing water leakage. When the device A is tightened to the bottom of the annular groove 13, the sealing gasket 5 provides a buffer.

[0032] It also includes a hose 6, which is connected to the second thread 221 of the movable tube 2. The hose 6 can be a stainless steel braided hose, a PVC hose, a rubber hose, etc.

[0033] As one embodiment, the other end of the hose 6 is used to connect to an angle valve B pre-embedded in the wall, thereby supplying water to device A, such as a toilet.

[0034] In another embodiment, the other end of the hose 6 is used to connect to the drain pipe, thereby discharging the wastewater from the basin through the movable pipe joint of this invention.
