Description

Technical Field

[0001] This application relates to the field of prefabricated water supply and drainage technology, and in particular to a prefabricated water supply and drainage system. Background Technology

[0002] Prefabricated water supply and drainage systems are devices used in industrial parks to drain water from buildings within the park. Water supply and drainage pipes are an indispensable part of the system, used to guide water flow and prevent excessive rainwater accumulation on the top floors of buildings in the industrial park.

[0003] According to Chinese Patent No. 202122556120.8, a prefabricated connection device for water supply and drainage pipes in prefabricated buildings includes a fixing plate, a connecting mechanism, and a crossbar. The outer wall of the fixing plate is connected to the connecting mechanism, which is composed of a threaded rod, a threaded hole A, a sleeve, and a nut. The outer wall of the fixing plate has two sets of symmetrical threaded holes A.

[0004] According to the aforementioned application documents, by attaching a fixing mechanism to the outside of the drainage pipe and then rotating two clamping blocks so that the inner walls of the two clamping blocks simultaneously contact the outer wall of the drainage pipe, and then fixing the fixing plate to the wall through a connecting mechanism, the drainage pipe can be supported. However, different sizes of drainage pipes need to be assembled when used on different types of buildings. If the size is too large, the two clamping blocks cannot be fixed with bolts, while if the size of the drainage pipe is too small, the inner wall of the clamping blocks cannot contact the outer wall of the drainage pipe, thus failing to achieve the fixing and support of the drainage pipe, reducing the versatility of the device when used, and also adversely affecting the normal installation of the drainage pipe. Therefore, a new type of prefabricated water supply and drainage system is needed.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address this problem, this application provides a prefabricated water supply and drainage system. The prefabricated water supply and drainage system provided in this application adopts the following technical solution:

[0007] A prefabricated water supply and drainage system includes two clamps for clamping the outside of pipes and a mounting base. One end of the two clamps is rotatably connected to the inner wall of the mounting base via a rotating shaft, and each of the two clamps is provided with a limiting component for limiting pipes of different sizes on an adjacent side.

[0008] The limiting assembly includes a limiting plate and a push rod. The limiting plate is slidably installed on one side of each of the two clamping plates. At least one guide tube is fixedly installed on one side of each of the two limiting plates. The push rod is elastically installed in the inner cavity of the guide tube, and the end of the push rod away from the inner cavity of the guide tube extends to the outside of the guide tube.

[0009] The limiting assembly also includes limiting bolts and limiting nuts. Mounting holes are provided on the adjacent sides of the two clamping plates. A limiting tube is fixedly installed in the inner cavity of the mounting hole. The limiting bolt is slidably installed in the inner cavity of the limiting tube. One end of the limiting bolt passes through the limiting tube and is rotatably connected to the side of the limiting plate away from the top rod. Two limiting nuts are installed on the outside of the limiting bolt through threaded engagement. The limiting tube is located between the two limiting nuts.

[0010] Preferably, the two limiting plates are both bent on the adjacent side.

[0011] Preferably, multiple guide tubes are fixedly installed in a ring on one side of the two limiting plates, and the middle of one end of each guide tube points to the center of the cavity formed by the two clamping plates.

[0012] Preferably, a top pressure spring is fixedly sleeved on the outer wall of the top rod, and the other end of the top pressure spring is fixedly connected to the bottom of the inner cavity of the guide tube.

[0013] Preferably, at least one positioning rod is fixedly installed on each of the two limiting plates on the side that is far apart from each other, and guide holes that are adapted to the positioning rods are opened on the adjacent side of the two clamping plates.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] With the limiting assembly, when the two clamps are fitted onto the outside of the conduit, the two clamps are rotated to close them, and then the two clamps are positioned. At this time, the two limiting plates are pushed to move them closer to the conduit until the ends of the push rods on both sides are in contact with the outer wall of the conduit. Continue to push the limiting plates until the top pressure spring is fully compressed. Then, pressure can be applied to the outside of the conduit through the push rods, thereby achieving the purpose of limiting conduits of different sizes. This improves the versatility of the device and reduces the adverse effects on the normal installation of the conduit. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0024] This application discloses a prefabricated water supply and drainage system. (Refer to...) Figure 1-4 It includes two clamping plates 2 for clamping the outside of the pipe and a mounting base. One end of the two clamping plates 2 is rotatably connected to the inner wall of the mounting base through a rotating shaft. Each of the two clamping plates 2 has a limiting component for limiting pipes of different sizes on an adjacent side. The mounting base is fixedly installed with a mounting plate at the end away from the clamping plates 2 through a connecting rod. The two clamping plates 2 are rotated to separate them, and then they are sleeved on the outside of the pipe. The mounting plate is then connected to the wall by expansion bolts, which can achieve the positioning of the clamping plates 2.

[0025] The limiting assembly includes a limiting plate 1 and a push rod 7. The limiting plate 1 is slidably installed on one side of each of the two clamping plates 2. At least one guide tube 8 is fixedly installed on one side of each of the two limiting plates 1. The push rod 7 is elastically installed in the inner cavity of the guide tube 8, and one end of the push rod 7 away from the inner cavity of the guide tube 8 extends to the outside of the guide tube 8. A top pressure spring 11 is fixedly sleeved on the outer wall of the push rod 7. The other end of the top pressure spring 11 is fixedly connected to the bottom of the inner cavity of the guide tube 8. The guide tube 8 can limit the sliding trajectory of the push rod 7 in order to improve the stability of the sliding of the push rod 7.

[0026] Furthermore, when the two clamps 2 are fitted onto the outside of the conduit, the two clamps 2 are rotated to close them, and then the two clamps 2 are positioned. At this time, the two limiting plates 1 are pushed to move them closer to the conduit until the ends of the push rods 7 on both sides are in contact with the outer wall of the guide tube 8. The limiting plates 1 are pushed until the top pressure spring 11 is in a fully compressed state. Pressure can then be applied to the outside of the conduit through the push rods 7, thereby achieving the purpose of limiting conduits of different sizes. This improves the versatility of the device and reduces the adverse effects on the normal installation of the conduit.

[0027] The limiting assembly also includes limiting bolts 4 and limiting nuts 5. Each of the two clamping plates 2 has an installation hole on one of its adjacent sides. A limiting tube 6 is fixedly installed in the inner cavity of the installation hole. The two ends of the limiting tube 6 extend through the installation hole to both sides of the clamping plate 2.

[0028] The limiting bolt 4 is slidably installed in the inner cavity of the limiting tube 6. The limiting tube 6 can limit the sliding trajectory of the limiting bolt 4, so as to improve the sliding stability of the limiting bolt 4.

[0029] One end of the limiting bolt 4 passes through the limiting tube 6 and the limiting plate 1 on the side away from the top rod 7 and is rotatably connected. Two limiting nuts 5 are installed on the outside of the limiting bolt 4 through threaded engagement. The limiting tube 6 is located between the two limiting nuts 5. When the top rod 7 clamps the outside of the conduit, the two limiting nuts 5 are rotated until the adjacent ends of the two limiting bolts 4 simultaneously contact the two ends of the limiting tube 6. This can achieve the function of positioning the limiting bolt 4, preventing the limiting bolt 4 from moving again and increasing the stability of the conduit.

[0030] The two limiting plates 1 are bent on their adjacent sides, which allows the two limiting plates 1 to form a circular cavity, allowing the push rod 7 to fit better against the outside of the catheter, and further increasing the stability of the catheter in the two clamps 2.

[0031] Multiple guide tubes 8 are fixedly installed in a ring on one side of the two limiting plates 1. The middle of one end of each guide tube 8 points to the center of the cavity formed by the two clamping plates 2. The ring-shaped guide tubes 8 are arranged in multiple rows along the side wall of the limiting plate 1, which allows multiple push rods 7 to contact the outer wall of the catheter at the same time. At the same time, depending on the different sizes of the catheter, different numbers of push rods 7 can contact the outer wall of the catheter, so as to improve the tightness of clamping catheters of different sizes.

[0032] At least one positioning rod 3 is fixedly installed on the side of each of the two limiting plates 1 that is far apart from each other. Guide holes that are compatible with the positioning rods 3 are opened on the side of each of the two clamping plates 2 that are adjacent to each other. Two positioning rods 3 are fixedly installed on the side of each of the two limiting plates 1 that is far apart from each other. The cooperation between the guide holes and the positioning rods 3 can limit the sliding trajectory of the limiting plate 1, prevent the limiting plate 1 from deviating when sliding, and improve the stability of the sliding of the limiting plate 1.

[0033] The end of the push rod 7 away from the bottom of the inner cavity of the guide tube 8 is designed as a spherical structure, which reduces the contact area between the end of the push rod 7 and the outer wall of the guide tube, thereby reducing the pressure of a single push rod 7 on the outer wall of the guide tube 8 and protecting the guide tube.

[0034] Mounting blocks 9 are fixedly installed on the side walls of the two clamping plates 2 away from the mounting base. Each of the two mounting blocks 9 has an insertion hole on an adjacent side that communicates with its other side. A fastening bolt 10 is slidably inserted into the inner cavity of one of the mounting holes. A fastening nut for limiting the other mounting block 9 is installed on the outside of the fastening bolt 10 through a threaded engagement. After the two clamping plates 2 are fitted onto the outside of the conduit, the two clamping plates 2 are rotated until the two mounting blocks 9 are parallel to each other. Then, one end of the fastening bolt 10 is inserted into the inner cavity of the other insertion hole through one of the insertion holes. Then, the fastening nut is installed on the outside of the fastening bolt 10 through a threaded engagement, which can achieve the function of limiting the two clamping plates 2.
