Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a tightening structure for building pipe laying. Background Technology

[0002] In the modern construction industry, the laying and installation of various pipeline systems are key links to ensure the normal operation of buildings and to guarantee the comfort and safety of residents. Among them, the pipe system is an important part of building drainage and sewage discharge. Its installation quality and stability are directly related to the drainage efficiency, sanitation conditions and maintenance costs during long-term use. In traditional pipe installation methods, the connection between pipes often relies on direct docking, flange connection or simple clamp fixation. Traditional connection methods are prone to problems such as loosening and leakage, which not only affect the normal operation of the drainage system, but may also damage the building structure and even cause safety hazards.

[0003] Existing pipe connections, whether hot-melt, electrofusion, or saddle-shaped, have poor toughness at the joints. Prolonged exposure to the flow and impact of the medium inside the pipe can easily lead to cracking or leakage at the joints, resulting in failure of the sealing effect and a short service life for the pipes.

[0004] The existing patent (publication number: CN214839059U) describes a pipe connection assembly. This utility model includes a connecting pipe, a straight pipe, a locking ring, and a sealing ring. The connecting pipe is connected to the straight pipe, and a first protrusion is provided inside the connecting pipe. The end of the straight pipe contacts the first protrusion. The sealing ring is fitted onto the straight pipe and connected to the connecting pipe. The connecting pipe, the straight pipe, and the sealing ring are locked together by the locking ring. This utility model of pipe connection assembly significantly improves the sealing effect and service life of pipe-to-pipe connections. Compared with traditional pipe connection methods, the installation method is simple, improving work efficiency and reducing construction time.

[0005] Existing patents offer solutions to the above problems, but they lack the requirement to tighten and reinforce the pipe connections, which can lead to loosening and cracking, resulting in leaks.

[0006] Therefore, a tightening structure for building pipe laying is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a tightening structure for building pipe laying, which can solve the problem that existing pipe connection components do not tighten and reinforce the pipe connection, resulting in the pipe connection being prone to loosening and cracking, and thus causing water leakage at the pipe connection.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a tightening structure for building pipe laying, comprising two pipes, one end of each pipe being provided with a flange, the two flanges being connected by multiple bolts, and a tightening mechanism being provided between the two pipes;

[0009] The tightening mechanism includes a bottom cover and a top cover disposed on the side wall of the pipe. Both the bottom cover and the top cover are snapped into the pipe. Each of the top cover and the bottom cover has a connecting seat and a locking seat on its side wall. A locking rod is hinged to the top of the connecting seat. A locking groove is formed on the top of the locking seat. The locking rod is movably connected to the locking groove. A locking nut is threaded to one end of the locking rod. The locking nut contacts the locking seat. The connecting seats and locking seats on different top covers and bottom covers are staggered. A connecting assembly is disposed between the bottom cover and the top cover.

[0010] Preferably, the connecting assembly includes a first connector disposed at both ends of the bottom cover, and a second connector disposed at both ends of the top cover. The top of the first connector is provided with two threaded cylinders, which are movably connected to the second connectors. A locking screw is threadedly connected to the middle of the threaded cylinder, and the locking screw is located above the second connector.

[0011] Preferably, a positioning frame is snapped onto the side wall of the first connector and the second connector. The positioning frame is C-shaped, and two inserts are fixedly connected to the inner wall of the positioning frame. Slots are provided on the side wall of the first connector and the second connector, and the inserts are adapted to the slots.

[0012] Preferably, an anti-detachment block is fixedly connected to the top of the positioning frame, and the anti-detachment block is movably connected to the locking screw.

[0013] Preferably, the top of the locking seat is provided with an anti-disengagement groove, the anti-disengagement groove is located on one side of the locking groove, and the locking nut is located inside the anti-disengagement groove.

[0028] 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.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A tightening structure for building pipe laying includes two pipes 1, one end of each pipe 1 is provided with a flange 2, the two flanges 2 are connected by multiple bolts 3, and a tightening mechanism 4 is provided between the two pipes 1.

[0031] The tightening mechanism 4 includes a bottom cover 41 and a top cover 42 disposed on the side wall of the pipe 1. Both the bottom cover 41 and the top cover 42 are snapped into the pipe 1. Both the top cover 42 and the bottom cover 41 are provided with a connecting seat 43 and a locking seat 44 on their side walls. A locking rod 45 is hinged to the top of the connecting seat 43. A locking groove 46 is opened on the top of the locking seat 44. The locking rod 45 is movably connected to the locking groove 46. A locking nut 47 is threaded to one end of the locking rod 45. The locking nut 47 contacts the locking seat 44. The connecting seats 43 and the locking seats 44 on different top covers 42 and bottom covers 41 are staggered. A connecting assembly 48 is provided between the bottom cover 41 and the top cover 42.

[0032] Specifically, such as Figure 2 As shown, the top of the locking seat 44 is provided with an anti-disengagement groove 9, which is located on one side of the locking groove 46, and the locking nut 47 is located inside the anti-disengagement groove 9.

[0033] Specifically, such as Figure 2 As shown, support heads 10 are fixedly connected to the side walls of both the connecting seat 43 and the locking seat 44, and the side walls of the support heads 10 are in contact with the flange 2.

[0034] Specifically, such as Figure 2 and Figure 4As shown, a positioning head 11 is provided on the side wall of the support head 10, and a positioning groove 12 is provided on the side wall of the flange 2. The positioning head 11 and the positioning groove 12 are adapted to each other.

[0035] Specifically, such as Figure 2 As shown, the locking rod 45 is fitted with an anti-slip sleeve 13 in the middle.

[0036] First, the bottom cover 41 and top cover 42 are respectively snapped onto the side walls of the two pipes 1. The connecting assembly 48 fixes the bottom cover 41 and top cover 42 onto the pipes 1. The side wall of the support head 10 contacts the flange 2, and the positioning head 11 on the side wall of the support head 10 is inserted into the positioning groove 12 on the side wall of the flange 2. Through the adaptation of the positioning head 11 and the positioning groove 12, the precise positioning between the bottom cover 41 and top cover 42 and the flange 2 is achieved, avoiding displacement during use. The support head 10 effectively prevents the connecting seat from being misaligned. 43. Regarding the problem of breakage between the locking seat 44 and the top cover 42 and the bottom cover 41, rotate the locking rod 45 around the hinge point so that one end enters the locking groove 46 on the top of the locking seat 44, achieving initial connection and positioning. Then, thread a locking nut 47 onto one end of the locking rod 45 and tighten the locking nut 47, ensuring tight contact between the locking nut 47 and the locking seat 44. As the locking nut 47 is continuously tightened, a pulling force will be applied to the bottom cover 41 and the top cover 42 through the locking rod 45, thereby... The two pipes 1 are brought together to tighten the connection. Simultaneously, the top of the locking seat 44 is provided with an anti-disengagement groove 9, located on one side of the locking groove 46. When the locking nut 47 is tightened, it will be located inside the anti-disengagement groove 9, effectively preventing the locking nut 47 from loosening or falling off during use, ensuring the stability of the tightening effect. An anti-slip sleeve 13 is fitted onto the middle of the locking rod 45. When the operator rotates the locking rod 45 for tightening, the anti-slip sleeve 13 increases the friction between the hand and the locking rod 45, making the operation more convenient and effortless. Thus, by setting up the tightening mechanism 4, and utilizing the cooperation of the locking rod 45, locking seat 44, and locking nut 47, additional tightening force can be applied to the connection of the two pipes 1, effectively compensating for the potential loosening risk that may exist if the connection is solely based on the flange 2 and bolts 3. This greatly enhances the stability of the pipe 1 connection, reduces the probability of leakage or displacement during pipe 1 use, and improves the safety and reliability of the entire building piping system.

[0037] Specifically, such as Figure 3 and Figure 5As shown, the connecting assembly 48 includes a first connector 481 disposed at both ends of the bottom cover 41, and a second connector 482 disposed at both ends of the top cover 42. Two threaded cylinders 483 are disposed on the top of the first connector 481. The threaded cylinders 483 are movably connected to the second connectors 482. A locking screw 484 is threadedly connected to the middle of the threaded cylinder 483. The locking screw 484 is located above the second connector 482.

[0038] Specifically, such as Figure 3 and Figure 5 As shown, a positioning frame 5 is snapped onto the side wall of the first connector 481 and the second connector 482. The positioning frame 5 is C-shaped. Two inserts 6 are fixedly connected to the inner wall of the positioning frame 5. Slots 7 are provided on the side wall of the first connector 481 and the second connector 482. The inserts 6 are adapted to the slots 7.

[0039] Specifically, such as Figure 3 As shown, an anti-detachment block 8 is fixedly connected to the top of the positioning frame 5, and the anti-detachment block 8 is movably connected to the locking screw 484.

[0040] In use, after installing the bottom cover 41 and top cover 42 onto the pipe 1, the second connector 482 is aligned with the first connector 481. At this time, the two threaded cylinders 483 on the top of the first connector 481 cooperate with the second connector 482 to achieve initial positioning of the first connector 481 and the second connector 482. The positioning frame 5 is then snapped onto the side walls of the first connector 481 and the second connector 482. The two inserts 6 fixedly connected to the inner wall of the positioning frame 5 are inserted into the slots 7 opened on the side walls of the first connector 481 and the second connector 482. Through the adaptation of the inserts 6 and the slots 7, precise positioning between the positioning frame 5 and the first connector 481 and the second connector 482 is achieved, ensuring the relative positioning of the first connector 481 and the second connector 482 during the connection process. The accurate positioning avoids any offset or misalignment, thus ensuring the stability and reliability of the entire connecting assembly 48. Next, the locking screw 484 is threaded to the middle of the threaded cylinder 483 and tightened. As the locking screw 484 is continuously tightened, the first connector 481 and the second connector 482 are tightly locked together, achieving a stable connection between the bottom cover 41 and the top cover 42. In addition, the anti-detachment block 8 fixedly connected to the top of the positioning frame 5 is movably connected to the locking screw 484, achieving anti-detachment and limiting of the positioning frame 5, preventing the positioning frame 5 from falling off. In this way, the connecting assembly 48, through the cooperation of the first connector 481, the second connector 482, the threaded cylinder 483, and the locking screw 484, can achieve a firm connection between the bottom cover 41 and the top cover 42. The tightening process of the locking screw 484 in the threaded cylinder 483 can tightly connect the first connector 481 and the second connector 482 together, effectively preventing the bottom cover 41 and the top cover 42 from loosening or separating during use, thereby enhancing the stability and reliability of the entire tightening structure and ensuring the normal operation of the building pipe system.

[0041] By adopting the above technical solution, the problem that the existing pipe 1 connection assembly 48 does not tighten and reinforce the connection of pipe 1 is solved, which leads to the problem that the connection of pipe 1 is prone to loosening and cracking, and thus causes water leakage at the connection of pipe 1.

[0042] Working Principle: In use, the bottom cover 41 and top cover 42 are first snapped onto the side walls of the two pipes 1 respectively. At this time, the two threaded cylinders 483 on the top of the first connector 481 are correspondingly engaged with the second connector 482. The positioning frame 5 is snapped onto the side walls of the first connector 481 and the second connector 482. The two inserts 6 fixedly connected to the inner wall of the positioning frame 5 are inserted into the slots 7 opened on the side walls of the first connector 481 and the second connector 482. Then, the locking screw 484 is threaded into the middle of the threaded cylinder 483. As the locking screw 484 is tightened, a stable connection is achieved between the bottom cover 41 and the top cover 42. The side wall of the support head 10 contacts the flange 2, and the positioning head 11 on the side wall of the support head 10 is inserted into the positioning groove 12 on the side wall of the flange 2. Through the adaptation of the positioning head 11 and the positioning groove 12, the bottom cover 41 and the top cover 42 are connected to the flange 2. The precise positioning between the support head 10 effectively prevents breakage between the connecting seat 43, locking seat 44, top cover 42, and bottom cover 41. The locking rod 45 is rotated around the hinge point so that one end enters the locking groove 46 on the top of the locking seat 44. Then, a locking nut 47 is threaded onto one end of the locking rod 45 and tightened so that the locking nut 47 is in close contact with the locking seat 44. As the locking nut 47 is tightened, the locking rod 45 applies a pulling force to the bottom cover 41 and the top cover 42, thereby bringing the two pipes 1 closer together and tightening the connection of the pipes 1. At the same time, the top of the locking seat 44 is also provided with an anti-disengagement groove 9, which is located on one side of the locking groove 46. When the locking nut 47 is tightened, it will be located inside the anti-disengagement groove 9, effectively preventing the locking nut 47 from loosening or falling off during use and ensuring the stability of the tightening effect.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
