Problems solved by technology

[0002] At present, the pipe clip structure used to fix the PVC drainage pipe is usually composed of an upper pipe clip body, a lower pipe clip body with an internal thread connection body, and a threaded steel nail. When installing, first use a tool to wedge the steel nail into the wall. Then screw the lower pipe clamp body with internal thread connection body into the steel nail. When the steel nail is wedged into the wall, the thread at the top of the steel nail is easily damaged and deformed by external force, so that the lower tube clamp body cannot be smoothly screwed into the steel nail to fix it. , a little force will cause the internal thread connection to break, increase the construction cost, and affect the construction progress
Moreover, the internal thread of the lower pipe card body connector needs to be put into the mold first, and then the outer thread insert is removed when the injection molding is completed. Repeated use in this way is time-consuming and labor-intensive, and increases labor costs.

Embodiment 1

[0026] like Figure 1 to Figure 3 As shown, this embodiment provides a PVC drainage pipe standpipe card, including a card body 1, and the card body 1 includes a first card body 3, a second card body 4, a screw and a nut 6; wherein, the first card body 3 and the second card body 4 are arranged symmetrically, the first card body 3 and the second card body 4 are all arranged in a semicircle, and connecting ears 12 are respectively arranged at the two ends of the semicircle, and the connecting ears 12 are provided with Connecting hole 10; the center position of the first card body semicircle is provided with through hole, and this through hole is in order to pass through for described threaded nail, and nut 6 cooperates with threaded nail, and the first card body 3 and the second The card body 4 is fixedly connected through the connecting hole 10 by bolts.

[0027] Wherein, the threaded nail is a steel nail, and the threaded nail includes a nail cap 2, a threaded cylinder 7 and a...

Embodiment 2

[0030] This embodiment provides a PVC drainage pipe riser card, the structure is as described in embodiment 1, the difference is that: the through hole at the center of the semicircle of the first card body is a countersunk hole, and the countersunk hole includes a circle Shaped groove 8 and bottom through hole 9, the inner diameter of circular groove 8 is slightly larger than the outer diameter of nail cap 2, and the inner diameter of bottom through hole 9 is slightly larger than the outer diameter of threaded cylinder 7, and this design is mainly to be convenient to the threaded nail At the same time, when the threaded screw passes through the counterbore, the nail cap 2 can be embedded in the circular groove 8, ensuring a smooth transition of the semicircular inner arc surface, and avoiding the protrusion of the nail cap 2 and affecting the PVC drainage pipe sleeve Stability when entering the first card body.

Embodiment 3

[0032] like figure 1 As shown, this embodiment provides a PVC drainage pipe standpipe card, the structure of which is as described in embodiment 1, the difference is that: in order to ensure the firmness and stability of the threaded nails during installation, the first card body is semicircular A convex body 5 is arranged on the outer arc surface of the body, the end surface of the convex body 5 is a vertical plane, and the through hole runs through the convex body 5. The advantage of this design is that when the nut 6 is matched with the threaded screw, the end face of the nut 6 can be in parallel contact with the end face of the convex body, and the convex body provides support to the screw, so that the nut can be connected to the screw. It is more firm and ensures the stability of the threaded nail when it is installed.

Abstract

The invention relates to a PVC drain pipe stand pipe clamp and a usage method thereof. The PVC drain pipe stand pipe clamp comprises a first clamp body, a second clamp body, a threaded screw and a screw cap; the first clamp body and the second clamp body are symmetrically arranged and are both in a semi-circular shape, the two ends of the semicircles are provided with connecting lugs respectively, and connecting holes are formed in the connecting lugs; a through hole is formed in the center of the first semi-circular clamp body and used for the threaded screw to penetrate through, the screw cap is matched with the threaded screw, and the first clamp body and the second clamp body are fixedly connected with each other in a mode that a bolt penetrates through the connecting hole. According to the PVC drain pipe stand pipe clamp, the top end of the threaded screw is provided with the screw cap, and when the clamp is installed and the threaded screw is wedged into a wall, deformation cannot prone to occurring; the through hole is formed in the center of the first clamp body, an inner thread does not need to be formed, therefore, the production process is easy, convenient and efficient, time and labor are saved, and meanwhile connection and installation are convenient.
