Description

Technical Field

[0001] This invention relates to the field of electromechanical pipeline connection technology in prefabricated buildings, and in particular to a prefabricated building electromechanical pipeline connection device. Background Technology

[0002] Prefabricated buildings or residences, as the name suggests, are buildings or residences assembled on site using prefabricated components from a factory. When installing prefabricated buildings, it is necessary to reserve space for the installation of prefabricated electromechanical pipelines for the installation and connection of these pipelines.

[0003] Existing prefabricated building electromechanical pipeline installation and connection devices are mostly only suitable for installing straight pipelines. At corners where bends occur, exposed lines can only be protected by filling with filler material. Therefore, some prefabricated building electromechanical pipeline connection devices that can bend at bends have emerged. However, existing prefabricated building electromechanical pipeline installation and connection devices can only bend 90 degrees in one direction at bends, which cannot meet the needs of prefabricated buildings for bends in different locations, and thus lacks practicality.

[0004] Therefore, it is necessary to provide a prefabricated building electromechanical pipeline connection device to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a prefabricated building electromechanical pipeline connection device.

[0006] This invention provides a prefabricated building electromechanical pipeline connection device, comprising a storage frame, wiring conduits, H-shaped plates, an angle adjustment device, a connecting pipe, through holes, a sealing plate, and a fixing and sealing device. The storage frame has a mounting groove in its center. Wiring conduits for storing pipelines are fixedly installed inside both mounting grooves by bolts. An H-shaped plate is fixedly installed inside one end of each wiring conduit. An angle adjustment device for adjusting the angle between the two storage frames is fixedly installed between the two H-shaped plates. A connecting pipe is fixedly installed between the two wiring conduits. Through holes are formed on the outer sides of the wiring conduits. A storage groove is formed in the storage frame corresponding to the through hole. A sealing plate is slidably installed inside the storage groove. A fixing and sealing device for securing the sealing plate is fixedly installed in the storage frame near the sealing plate. In use, the pipeline is first passed through the two storage frames, and then the angle adjustment device allows for different turning positions of the two storage frames. After installation, the pipeline is connected at the through hole and storage groove, and then the fixing and sealing device seals the through hole and storage groove.

[0007] Preferably, the connecting pipe is a corrugated pipe. When the two storage frames rotate, the compression and rotation of the connecting pipe can seal the space between the two wiring pipes, thus protecting the wiring.

[0008] Preferably, the angle adjustment device includes a first connecting rod, a ball bearing, a second connecting rod, a cylindrical fixing block, a positioning block, and a thrust spring. The first connecting rod is fixedly installed on one side of an H-shaped plate, and a ball bearing is fixedly installed at the end of the first connecting rod away from the H-shaped plate. The second connecting rod is fixedly installed on one side of the other H-shaped plate, and a cylindrical fixing block is fixedly installed at the end of the second connecting rod away from the H-shaped plate. A groove is formed in the middle of the cylindrical fixing block, and the ball bearing rolls within the groove. Positioning holes are arranged in a circular array corresponding to the positions of the grooves on the cylindrical fixing block. The positioning hole and the roller groove are connected. A limit groove is formed inside the cylindrical fixing block corresponding to the positioning hole. A positioning block is slidably installed in the middle of the limit groove. A limit hole is symmetrically formed in the middle of the positioning block. A limit rod is symmetrically fixed inside the cylindrical fixing block corresponding to the limit groove. The limit rod is slidably connected to the limit hole. A thrust spring is sleeved on the outside of the limit rod. One end of the thrust spring is fixedly connected to one end of the cylindrical fixing block corresponding to the limit groove, and the other end of the thrust spring is fixedly connected to one side of the positioning block. A bevel is formed on the side of the positioning block away from the thrust spring. By storing the first connecting rod in positioning holes at different positions, different turning positions of the two storage frames can be achieved, increasing the usability of building electromechanical pipelines.

[0009] Preferably, the inner wall of the groove is tightly fitted to the outer side of the ball, ensuring stable rotation of the ball within the groove.

[0010] Preferably, the distance between the side of the positioning block away from the inclined plane and the end of the positioning hole is the same as the radius of the first connecting rod. This ensures that the first connecting rod is stably housed inside the positioning hole.

[0011] Preferably, the fixing sealing device includes a support rod, a rotating cylinder, a torsion spring, a lever, and an obtuse-angle positioning plate. The storage frame has symmetrically formed fixing slots corresponding to the storage grooves. A support rod is fixedly installed inside the fixing slots of the storage frame. A rotating cylinder is rotatably mounted on the middle of the support rod. Torsion springs are symmetrically fitted at both ends of the fixing slots. One end of each torsion spring is fixedly connected to the end of the storage frame corresponding to the fixing slot, and the other end is fixedly connected to one end of the rotating cylinder. A lever is integrally fixedly installed on the outer side of the rotating cylinder, and an obtuse-angle positioning plate is integrally fixedly installed on the outer side of the rotating cylinder. By moving the lever, the sealing plate slides into the storage groove. Releasing the lever causes the torsion spring to press the bottom side of the obtuse-angle positioning plate against the sealing plate, thus sealing the storage groove.

[0012] Preferably, a sealing gasket is fixedly installed in the storage frame at the position corresponding to the storage slot. This achieves a seal between the sealing plate and the storage slot.

[0013] Preferably, the inner side of the storage slot has a chamfer to facilitate the sliding of the sealing plate into the storage slot.

[0014] Compared with related technologies, the present invention provides the following beneficial effects:

[0015] Compared with the prior art, this invention improves the usability of building electromechanical pipelines by passing the pipeline through the wiring conduit in the two storage frames beforehand, rotating the first connecting rod into the positioning holes at different positions, and controlling the rotation angle of the first connecting rod through the operation of the angle adjustment device. This allows for different turning positions of the two storage frames and expands their usability. After installation, the pipeline is connected through the through hole and the storage groove, and the sealing plate is slid into the inside of the storage groove. The storage groove is sealed through the operation of the fixing and sealing device. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 6A prefabricated building electromechanical pipeline connection device includes a storage frame 1, a wiring conduit 3, an H-shaped plate 4, an angle adjustment device 5, a connecting pipe 6, a through hole 7, a sealing plate 9, and a fixing sealing device 10. The storage frame 1 has a mounting groove 2 in the middle. Wiring conduits 3 for storing pipelines are fixedly installed inside both mounting grooves 2 by bolts. An H-shaped plate 4 is fixedly installed inside one end of the wiring conduit 3. An angle adjustment device 5 for adjusting the angle between the two storage frames 1 is fixedly installed between the two H-shaped plates 4. A connecting pipe 6 is fixedly installed between the two wiring conduits 3. A through hole 7 is opened on the outside of the wiring conduit 3. A storage groove 8 is opened on the storage frame 1 corresponding to the through hole 7. A sealing plate 9 is slidably installed inside the storage groove 8. A fixing sealing device 10 for fixing the sealing plate 9 is fixedly installed on the storage frame 1 near the sealing plate 9. When the device is in use, the pipeline is first passed through the wiring conduit 3 in the two storage boxes 1, and then the angle adjustment device 5 is used to change the different turning positions of the two storage boxes 1. After installation, the pipeline is connected at the through hole 7 and the storage groove 8, and then the through hole 7 and the storage groove 8 are sealed by the use of the fixing sealing device 10.

[0025] Please refer to the following: Figures 1 to 6 The connecting pipe 6 is a corrugated pipe. When the two storage boxes 1 rotate, the compression and rotation of the connecting pipe 6 can seal the space between the two wiring pipes 3, thus protecting the wiring.

[0026] Please refer to the following: Figures 1 to 6The angle adjustment device 5 includes a first connecting rod 51, a ball bearing 52, a second connecting rod 53, a cylindrical fixing block 54, a positioning block 58, and a thrust spring 510. The first connecting rod 51 is fixedly installed on one side of an H-shaped plate 4, and a ball bearing 52 is fixedly installed at the end of the first connecting rod 51 away from the H-shaped plate 4. The second connecting rod 53 is fixedly installed on one side of another H-shaped plate 4, and a cylindrical fixing block 54 is fixedly installed at the end of the second connecting rod 53 away from the H-shaped plate 4. A groove 55 is formed in the middle of the cylindrical fixing block 54, and the ball bearing 52 rolls within the groove 55. Positioning holes 56 are arranged in a circular array corresponding to the positions of the grooves 55 on the cylindrical fixing block 54. The positioning holes 56 are connected to the ball bearing 52 in a circular pattern. The groove 55 is connected. The cylindrical fixing block 54 has a limiting groove 57 inside the corresponding positioning hole 56. The positioning block 58 is slidably installed in the middle of the limiting groove 57. The positioning block 58 has a limiting hole 512 symmetrically opened in the middle of the positioning block 58. The cylindrical fixing block 54 has a limiting rod 59 symmetrically fixedly installed inside the corresponding limiting groove 57. The limiting rod 59 is slidably connected to the limiting hole 512. A thrust spring 510 is sleeved on the outside of the limiting rod 59. One end of the thrust spring 510 is fixedly connected to one end of the cylindrical fixing block 54 corresponding to the limiting groove 57. The other end of the thrust spring 510 is fixedly connected to one side of the positioning block 58. The side of the positioning block 58 away from the thrust spring 510 has an inclined surface 511. When the two storage frames 1 change to different turning positions, the first connecting rod 51 is rotated and retracted into the positioning holes 56 at different positions. At this time, the first connecting rod 51 will press the inclined surfaces 511 of the two positioning blocks 58 inside the positioning holes 56, causing the positioning blocks 58 to be retracted into the limiting grooves 57. At this time, the thrust spring 510 is in a compressed state. When the first connecting rod 51 is completely retracted into the positioning blocks 58, the first connecting rod 51 will not press the inclined surfaces 511 of the positioning blocks 58. The two positioning blocks 58 relative to the positioning blocks 58 will slide out of the limiting grooves 57 through the push of the thrust spring 510, thereby controlling the rotation angle of the first connecting rod 51 and realizing the change of different turning positions of the two storage frames 1, thus improving the application range of building electromechanical pipelines.

[0027] Please refer to the following: Figures 1 to 6 The inner wall of the groove 55 is tightly fitted to the outer side of the ball 52, enabling stable rotation of the ball 52 within the groove 55.

[0028] Please refer to the following: Figures 1 to 6 The distance between the side of the positioning block 58 away from the inclined surface 511 and the end of the positioning hole 56 is the same as the radius of the first connecting rod 51. This ensures that the first connecting rod 51 is stably housed inside the positioning hole 56.

[0029] Please refer to the following: Figures 1 to 6The fixed sealing device 10 includes a support rod 102, a rotating cylinder 103, a torsion spring 104, a lever 105, and an obtuse angle positioning plate 106. The storage frame 1 has a fixed groove 101 symmetrically opened at the position corresponding to the storage slot 8. The support rod 102 is fixedly installed inside the fixed groove 101 of the storage frame 1. The rotating cylinder 103 is rotatably installed in the middle of the support rod 102. The two ends of the fixed groove 101 are symmetrically fitted with torsion springs 104. One end of the torsion spring 104 is fixedly connected to the end of the storage frame 1 corresponding to the fixed groove 101. The other end of the torsion spring 104 is fixedly connected to one end of the rotating cylinder 103. The lever 105 is integrally fixedly installed on the outside of the rotating cylinder 103. The obtuse angle positioning plate 106 is integrally fixedly installed on the outside of the rotating cylinder 103. By moving the lever 105, the sealing plate 9 is slid into the storage groove 8. At this time, the torsion spring 104 is in a torsion state. When the lever 105 is released, the operation of the torsion spring 104 causes the bottom side of the obtuse angle positioning plate 106 to press the sealing plate 9, thereby sealing the storage groove 8.

[0030] Please refer to the following: Figures 1 to 6 A sealing gasket 11 is fixedly installed in the storage frame 1 at the position corresponding to the storage slot 8. This achieves a seal between the sealing plate 9 and the storage slot 8.

[0031] Please refer to the following: Figures 1 to 6 The inner side of the storage slot 8 is chamfered to facilitate the sliding of the sealing plate 9 into the storage slot 8.

[0032] When the device is in use, the wiring is first passed through the wiring conduit 3 in the two storage frames 1, and the first connecting rod 51 is rotated and stored into the positioning holes 56 at different positions. At this time, the first connecting rod 51 will press the inclined surfaces 511 of the two positioning blocks 58 inside the positioning holes 56, causing the positioning blocks 58 to be stored into the limiting grooves 57. At this time, the thrust spring 510 is in a compressed state. When the first connecting rod 51 is completely stored inside the positioning blocks 58, the first connecting rod 51 will not press the inclined surfaces 511 of the positioning blocks 58. The two positioning blocks 58 relative to the positioning blocks 58 will slide out of the limiting grooves by the push of the thrust spring 510. The groove 57 controls the rotation angle of the first connecting rod 51, enabling different turning positions of the two storage frames 1, thus improving the usability of building electromechanical pipelines. After installation, the pipeline is connected through the through hole 7 and the storage groove 8. Then, by moving the lever 105, the sealing plate 9 is slid into the interior of the storage groove 8. At this time, the torsion spring 104 is in a torsional state. Releasing the lever 105 causes the bottom side of the obtuse angle positioning plate 106 to press against the sealing plate 9, thereby sealing the storage groove 8.
