Description

Technical Field

[0001] This utility model relates to the field of building embedded parts technology, specifically to an embedded part for building water supply and drainage pipes. Background Technology

[0002] As is well known, embedded parts are components that are pre-installed (buried) within concealed works. They are components placed during structural pouring and used for overlapping during the construction of the superstructure. This facilitates the installation and fixing of external engineering equipment foundations. Embedded parts are mostly made of metal, such as reinforcing steel or cast iron, but non-metallic rigid materials such as wood and plastic can also be used.

[0003] According to a public notice (Announcement No.: CN218625974U) regarding an embedded component for building water supply and drainage pipes, the aforementioned application utilizes a protective outer pipe and support block, with a metal plate inside the protective pipe wall, to effectively protect the embedded pipe and prevent concrete from compressing it, thus ensuring its normal use. Furthermore, the formation of a sealed cavity between the protective outer pipe and the embedded pipe, with a vacuum inside, reduces noise from the drainage pipe inside the embedded component. Finally, the clamping pipe and nut work together to secure the drainage pipe, improving the device's fixing effect.

[0004] If there are gaps on both sides of the clamping tube and the nut cannot completely cover the clamping tube, sand and gravel can easily enter the interior of the clamping tube through the gaps, causing the nut to be unable to be tightened properly, the clamping tube to shrink and fail, and the drain pipe to be not securely fixed. Utility Model Content

[0005] The purpose of this utility model is to provide an embedded part for building water supply and drainage pipes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embedded component for building water supply and drainage pipes, comprising an embedded pipe, a protective outer pipe, a connecting cap, a clamping pipe, and a nut. The bottom surface of the nut has a positioning groove. The outer wall of the clamping pipe is fitted with a protective component, which includes a corrugated pipe. The corrugated pipe is fixedly connected to the surface of the connecting cap and is fitted onto the outer wall of the clamping pipe. A metal ring is fixedly connected to the top of the corrugated pipe, and a telescopic rod is fixedly connected to the bottom surface of the metal ring. The bottom end of the telescopic rod is fixedly connected to the surface of the connecting cap. The metal ring and the surface of the connecting cap are elastically connected by a support spring, which is fitted onto the outer wall of the telescopic rod. An annular groove is formed inside the metal ring.

[0007] Preferably, the annular groove is provided with an anti-detachment component, which includes a ratchet and a pawl. The ratchet is rotatably connected to the inside of the annular groove, and a ring is fixedly connected to the surface of the ratchet. Multiple arrayed positioning blocks are fixedly connected to the surface of the ring, and the positioning blocks are inserted into the inside of the positioning groove.

[0008] Preferably, the protective outer tube is fixedly connected to the outside of the pre-embedded tube, and the connecting cap is threadedly connected to the end of the pre-embedded tube.

[0009] Preferably, the pawl is elastically connected to the inner wall of the annular groove via an elastic sheet.

[0010] Preferably, the pawl is hinged to the inner wall of the annular groove and engages with the outer ring wall of the ratchet.

[0011] Preferably, the clamping tube is fixedly connected to the surface of the connecting cover, and the nut is threadedly connected to the end of the clamping tube.

[0012] Compared with the prior art, this utility model provides an embedded part for building water supply and drainage pipes, which has the following beneficial effects:

[0013] 1. The pre-embedded parts for the building's water supply and drainage pipes achieve dynamic protection and sealing of the clamping pipe through the elastic combination of the corrugated pipe of the protective component and the support spring. The clamping pipe is completely wrapped to prevent sand and gravel from entering the interior through the gaps, thereby avoiding the inability of the nut to be tightened properly, the clamping pipe shrinking and failing, and the drainage pipe not being firmly fixed.

[0014] 2. The pre-embedded parts for the building's water supply and drainage pipes, through the one-way locking structure of the ratchet and pawl of the anti-loosening component, combined with the insertion and positioning of the positioning block and positioning groove, improve the resistance to vibration and loosening, and ensure the long-term reliability of the water supply and drainage pipes.

Detailed Implementation

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a pre-embedded component for building water supply and drainage pipes, including a pre-embedded pipe 1, a protective outer pipe 2, a connecting cap 3, a clamping pipe 4, and a nut 5. The bottom surface of the nut 5 is provided with a positioning groove 51. The protective outer pipe 2 is fixedly connected to the outside of the pre-embedded pipe 1. The connecting cap 3 is threadedly connected to the end of the pre-embedded pipe 1. The clamping pipe 4 is fixedly connected to the surface of the connecting cap 3. The nut 5 is threadedly connected to the end of the clamping pipe 4. The protective outer pipe 2 is used to be pre-embedded in the building structure to provide basic support and protection for pipe installation. The connecting cap 3 and the clamping pipe 4 form an interface for pipe connection. The nut 5 is used to fasten the pipe joint.

[0021] like Figures 1-4 As shown, a protective component 6 is fitted onto the outer wall of the clamping tube 4. The protective component 6 includes a bellows 61, which is fixedly connected to the surface of the connecting cover 3. The bellows 61 is fitted onto the outer wall of the clamping tube 4, and a metal ring 62 is fixedly connected to the top end of the bellows 61. The bellows 61 is telescopic and can extend and retract with the movement of the metal ring 62. A telescopic rod 63 is fixedly connected to the bottom surface of the metal ring 62, and the bottom end of the telescopic rod 63 is fixedly connected to the surface of the connecting cover 3. The metal ring 62 and the surface of the connecting cover 3 are elastically connected by a support spring 64, which is fitted onto the outer wall of the telescopic rod 63. The support spring 64 provides an upward elastic force, and the telescopic rod 63 restricts the movement trajectory of the metal ring 62, keeping the bellows 61 stable under pressure or tension, thus enhancing the protective effect. When the nut 5 is threadedly connected to the clamping tube 4, the support spring 64 provides elastic support to the metal ring 62, making the metal ring 62 fit tightly against the bottom surface of the nut 5. The clamping tube 4 is wrapped inside by the corrugated tube 61 and the nut 5, thus preventing sand and gravel from entering the interior of the clamping tube 4 through the gaps.

[0022] like Figures 1-4As shown, an anti-disengagement component 7 is provided inside the annular groove 65. The anti-disengagement component 7 includes a ratchet 71 and a pawl 72. The ratchet 71 is rotatably connected inside the annular groove 65, and the pawl 72 is hinged to the inner wall of the annular groove 65 and engages with the outer ring wall of the ratchet 71. The pawl 72 is elastically connected to the inner wall of the annular groove 65 through an elastic plate 73. The elastic plate 73 provides elastic support for the pawl 72, so that the pawl 72 engages with the outer ring wall of the ratchet 71, allowing the ratchet 71 to rotate only clockwise. A ring 74 is fixedly connected to the surface of the ratchet 71, and multiple arrayed positioning blocks 75 are fixedly connected to the surface of the ring 74. The positioning blocks 75 are inserted into the positioning groove 51. Through the positioning of the positioning blocks 75 and the positioning groove 51, the nut 5 can only be tightened clockwise on the clamping tube 4 and cannot rotate counterclockwise, thereby restricting the circumferential rotation of the nut 5, preventing the nut 5 from loosening, and ensuring the reliability of the connection. When it is necessary to rotate the nut 5 in the opposite direction, the metal ring 62 is pressed down to compress the support spring 64, causing the positioning block 75 to separate from the positioning groove 51.

[0023] In this utility model, during use, the positioning groove 51 on the bottom surface of the nut 5 is inserted into the positioning block 75, and the nut 5 is screwed in clockwise along the outer wall thread of the clamping tube 4. As the nut 5 is tightened, the support spring 64 and the bellows 61 are in a downward compressed state, the metal ring 62 is tightly fitted with the nut 5, and the bellows 61 wraps around the clamping tube 4, thereby preventing sand and gravel from entering the interior of the clamping tube 4 from the gaps.

[0024] During the tightening of nut 5, ratchet 71 rotates clockwise synchronously with nut 5. Pad 72, under the action of elastic plate 73, engages in the tooth groove of ratchet 71, forming a one-way lock. At this time, nut 5 can only rotate clockwise and cannot rotate counterclockwise, thus preventing nut 5 from loosening. When it is necessary to rotate nut 5 in the opposite direction, pressing down on metal ring 62 compresses support spring 64, causing positioning block 75 to separate from positioning groove 51, allowing nut 5 to rotate in the opposite direction.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
