Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a prefabricated railing rapid assembly system. Background Technology

[0002] In the field of construction engineering, prefabricated railings are widely used due to their high construction efficiency and high degree of standardization. The flexibility and convenience of their assembly system directly affect the construction progress and safety. With the popularization of prefabricated buildings, traditional railing assembly systems are unable to meet the needs of rapid construction in complex building environments due to problems such as fixed installation angles, cumbersome multi-group connections, and poor adjustability. There is an urgent need to optimize the installation process and environmental adaptability of railings through structural innovation.

[0003] Existing prefabricated railing assembly systems have significant drawbacks: First, the installation angle is difficult to adjust. Traditional systems mostly use fixed installation structures, and the railing orientation needs to be prefabricated. When encountering scenarios such as curved balconies or irregularly shaped walls, installation difficulties or reduced safety often occur due to mismatched angles. Second, the connection efficiency of multiple railings is low, relying on bolt fastening or welding methods. This not only involves cumbersome installation steps, which are time-consuming and labor-intensive, but also require professional tools, making it difficult to meet the needs of rapid on-site assembly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated railing rapid assembly system, which aims to solve the problems of fixed installation angle, cumbersome connection, and poor environmental adaptability in existing prefabricated railing assembly systems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A prefabricated railing quick assembly system includes two half-bars, each half-bar having an internal cavity. The two adjacent ends of the left sides of the two half-bars are connected by a connecting strip, and a main bar is fixedly connected to the opposite ends of the left sides of each half-bar. The adjacent sides of the main bars are connected by multiple protective bars. An installation tube is connected to the opposite sides of the cavities at both ends via a rotating assembly. A rotating groove is formed at the opposite ends of the right sides of each half-bar. Grooves are formed on the top and bottom sides of the outer wall of the installation tube, and through holes are formed on the adjacent sides of the grooves at both ends. A fixing assembly is disposed inside the groove.

[0007] Furthermore, the rotating assembly includes a turntable, with the opposite sides of the two turntables respectively rotatably connected to the opposite sides of the two cavities, and spline grooves provided on the adjacent sides of the two turntables. A mounting tube is fixedly connected to the right side of the turntable through the groove.

[0008] Furthermore, a knob is rotatably connected to the adjacent side of the two halves of the rod. A screw is fixedly connected inside the knob. A movable disk is sleeved on the top and bottom of the outer wall of the screw. A spline shaft is fixedly connected to the opposite side of the movable disks at both ends. The spline shaft is sleeved on the outer wall of the screw, and the outer wall of the spline shaft is located inside the spline groove.

[0009] Furthermore, limit grooves are provided on both the left and right sides of the cavity, and limit sliders are fixedly connected to both the left and right sides of the movable disk. The outer wall of the limit slider is slidably connected to the inside of the limit groove.

[0010] Furthermore, the fixing component includes a spring, one end of which is connected to a proximal side of the grooves at both ends, and the other end is connected to an inclined receiving block. The proximal side of the outer wall of the inclined receiving block at both ends is slidably connected to the inside of the grooves at both ends. A limit rod is fixedly connected to the proximal side of the inclined receiving block at both ends, and the outer wall of the limit rod is slidably connected to the inside of the through hole.

[0011] Furthermore, the outer wall of the mounting tube is rotatably connected to a rotating ring, and the top and bottom ends of the rotating ring are provided with inclined abutment grooves, with the opposite ends of the outer walls of the inclined abutment blocks located inside the inclined abutment grooves.

[0012] Furthermore, a mounting rod is fixedly connected to the left side of the main rod, and a fixing groove is provided on both the top and bottom sides of the mounting rod.

[0013] Furthermore, a base is fixedly connected to the bottom side of the bottom half rod, and mounting plates are fixedly connected to the bottom ends of both the front and rear sides of the base. A circular hole is opened inside the mounting plate, and a screw is installed inside the circular hole.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the half-bar is placed in the installation position, and the mounting plate is fixed to the base with screws. Rotating the knob drives the screw, moving plate and spline shaft to move. After the spline shaft leaves the spline groove, the rotating plate can be rotated to adjust the orientation of the mounting tube. Rotating the knob in the opposite direction makes the spline shaft re-enter the spline groove. Because the spline groove has more teeth than the spline shaft, it can adapt to different angles, realizing free adjustment of the orientation of the mounting tube and the subsequent installation position of the railing.

[0016] In this utility model, when installing subsequent railings, the installation rod is inserted into the installation tube, and after confirming the landing point of the base, it is fixed with screws. The rotating ring is rotated so that its inclined surface abuts against the inclined surface of the inclined surface receiving block, pushing the inclined surface receiving block to drive the limiting rod into the fixing groove, thus fixing the installation rod. This achieves quick fixing of the two railings, which is easy to operate and improves assembly efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-3This utility model provides an embodiment of a prefabricated railing quick assembly system, comprising two half-bars 1, each half-bar 1 having an internal cavity. The two near ends of the two half-bars 1 are connected by connecting strips 7, and the two far ends of the two half-bars 1 are fixedly connected to main rods 8. The near sides of the two main rods 8 are connected by multiple protective rods 9. The far sides of the two cavities are connected to mounting tubes 2 via turntables 11. The far ends of the two half-bars 1 have rotating grooves 18. The top and bottom sides of the outer wall of the mounting tubes 2 have grooves, and the near sides of the grooves at both ends have through holes. Springs 22 are installed inside the grooves. The far sides of the turntables 11 at both ends are rotatably connected to the far sides of the two cavities at both ends. The near sides of the turntables 11 at both ends have spline grooves 15. The right side of the turntable 11... A side through-groove 18 is fixedly connected to an installation tube 2. A knob 3 is rotatably connected to the adjacent side of the two half rods 1. A screw 13 is fixedly connected inside the knob 3. A movable disk 12 is sleeved on the top and bottom of the outer wall of the screw 13. A spline shaft 14 is fixedly connected to the opposite side of the two movable disks 12. The spline shaft 14 is sleeved on the outer wall of the screw 13. The outer wall of the spline shaft 14 is located inside the spline groove 15. Limiting grooves 24 are opened on both the left and right sides of the cavity. Limiting sliders 17 are fixedly connected to both the left and right sides of the movable disks 12. The outer wall of the limiting sliders 17 is slidably connected inside the limiting grooves 24. A base 4 is fixedly connected to the bottom side of the bottom half rod 1. Mounting pieces 5 are fixedly connected to the bottom of the front and rear sides of the base 4. A round hole is opened inside the mounting piece 5. A screw 6 is installed inside the round hole.

[0026] Specifically, when using this prefabricated railing quick assembly system, the operation process revolves around fixing a single railing, adjusting its orientation, and connecting multiple railings. First, place the bottom end of half-rail 1 in the installation position, and use screws 6 to fix the mounting plate 5 and base 4 through the round hole to complete the half-rail fixing. Turning knob 3 drives screw 13 to rotate, causing moving disc 12 and spline shaft 14 to move. After the spline shaft disengages from spline groove 15, turn disc 11 is rotated to adjust the orientation of mounting tube 2. After adjustment, turn knob 3 is rotated in the opposite direction. Because spline groove 15 has more teeth than spline shaft 14, spline shaft 14 can be re-embedded into spline groove 15, realizing flexible adjustment of the orientation of mounting tube 2 and the subsequent railing installation position.

[0027] Reference Figure 1 , Figure 4 and Figure 5One end of the spring 22 is connected to the adjacent side of the grooves at both ends, and the other end is connected to the inclined support block 21. The adjacent side of the outer wall of the inclined support block 21 at both ends is slidably connected to the inside of the grooves at both ends. The adjacent side of the inclined support block 21 at both ends is fixedly connected to the limit rod 23. The outer wall of the limit rod 23 is slidably connected to the inside of the through hole. The outer wall of the mounting tube 2 is rotatably connected to the rotating ring 16. The top and bottom ends of the rotating ring 16 are provided with inclined abutment grooves 20. The opposite ends of the outer walls of the inclined support blocks 21 at both ends are located inside the inclined abutment grooves 20. The left side of the main rod 8 is fixedly connected to the mounting rod 10. The top and bottom sides of the mounting rod 10 are provided with fixing grooves 19.

[0028] Specifically, when installing subsequent railings, first insert the installation rod 10 into the installation tube, determine the landing point of the second railing base, and fix it with screws. Then rotate the rotating ring 16, and its inclined surface abuts against the inclined surface receiving block 21. Push the inclined surface receiving block to move the limiting rod 23 into the fixing groove 19, fix the installation rod, and complete the quick connection of the two sets of railings. This system realizes flexible installation and rapid assembly of prefabricated railings through the spline limiting adjustment structure and the inclined surface abutment fixing structure.

[0029] Working principle: In use, first place the bottom half rod 1 at the desired installation position, then pass the screw 6 through the round hole and fix it in place, thereby fixing the mounting plate 5 and the base 4, and thus fixing the half rod 1. Turning the knob 3 drives the screw 13 to rotate, thereby moving the two moving discs 12 and the spline shaft 14, causing the spline shaft 14 to leave the inside of the spline groove 15, releasing the limit on the turntable 11. Then, the orientation of the mounting tube 2 can be adjusted by rotating the turntable 11. After adjustment, turn the knob 3 in the opposite direction to make the spline shaft 14 re-enter the inside of the spline groove 15. Since the spline groove 15 has more grooves than the spline shaft 14, the spline groove 15... The turntable 11 can adapt to different angles, and the spline shaft 14 can enter the spline groove 15. This allows for free adjustment of the orientation of the mounting tube 2 and the position of the next railing according to the installation environment. When installing the next railing, first insert the mounting rod 10 into the mounting tube 2 to confirm the landing point of the second railing base 4. Then, fix the second railing with screws 6. Finally, rotate the rotating ring 16 so that the inclined surface of the rotating ring 16 abuts against the inclined surface of the inclined surface receiving block 21, thereby pushing the inclined surface receiving block 21 to move the limiting rod 23 and allow the limiting rod 23 to enter the fixing groove 19 to fix the mounting rod 10. This allows the two railings to be fixed together.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
