Description

Technical Field

[0001] This utility model relates to the field of building pipe connection technology, specifically an adaptive sealing connection device for building pipe installation. Background Technology

[0002] Pipeline installation is a crucial part of building construction, and the quality of the sealing connections between pipes directly affects the operational stability and safety of the entire pipeline system. Currently, commonly used sealing connection methods in building pipeline installation include flange connections, threaded connections, and socket connections. However, these traditional connection methods have significant drawbacks:

[0003] First, flange connections require multiple sets of bolts and nuts to be tightened one by one. Installation necessitates repeated calibration of bolt force balance, and disassembly requires unscrewing each bolt individually, making the process cumbersome and time-consuming, especially in confined construction environments where tool access is limited, further reducing efficiency. Second, threaded connections rely on thread engagement for sealing. Precise control of the tightening depth is crucial during installation; overtightening can damage the threads. If thread corrosion or jamming occurs during disassembly, specialized tools are needed to destroy the connection structure, making reuse difficult. Third, socket connections often rely on adhesive or sealing rings for sealing. Disassembly after adhesive curing requires damaging the pipe interface, and replacing aged sealing rings requires complete pipe separation, resulting in high maintenance costs and poor flexibility. However, building pipes used for temporary purposes, frequent maintenance, and space modifications require frequent disassembly and assembly, demanding high ease of installation and disassembly. Therefore, traditional pipe connection structures are insufficient to meet these needs and require improvement. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adaptive sealing connection device for building pipeline installation. By setting up a boss, a connecting plate, a quick-locking component, an irregularly shaped limiting block, and a rotating ring, it can achieve quick locking between two pipe fittings with just one action. It is easy to assemble and disassemble and can meet the connection needs of building pipelines that require frequent maintenance. It solves the problems of inconvenience and poor usability of current building pipeline connection methods.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An adaptive sealing connection device for building pipe installation includes a pipe 1 and a pipe 2. A flange 1 is fixedly connected to the outer wall of the pipe 1 near the pipe 2 via a support rod. A boss 1 with an annular cross-section is integrally formed on one side of the flange 1, and an array of connecting plates is fixedly connected to the boss 1 near the pipe 2. A flange 2 is fixedly connected to the outer wall of the pipe 2 near the pipe 1 via a support rod. A boss 2 with an annular cross-section is integrally formed on one side of the flange 2. A connecting hole penetrating the flange 2 is opened at the corresponding position of the connecting plate. The connecting hole is adapted to the connecting plate, and a quick-locking component is installed on the side of the boss 2 located at the connecting hole to achieve locking and positioning after the connecting plate is inserted into the connecting hole.

[0009] Furthermore, the quick-locking component includes a pad plate, which is fixedly connected to the outer wall of the second boss; a locking rod, which is slidably connected to the corresponding holes in the pad plate and the second boss, and a locking hole adapted to the locking rod is provided on the connecting plate, so that the locking rod can be inserted into the locking hole to lock and fix the connecting plate; an arc-shaped protrusion integrally formed on the lower end of the locking rod; a protective cap fixedly connected to the upper end of the locking rod; and a spring sleeved on the locking rod, with its two ends abutting against the pad plate and the protective cap respectively.

[0010] Furthermore, a rotating ring is rotatably connected to the side of the flange two near the pipe one, and an array of irregularly shaped limiting blocks are fixedly connected to the inner wall of the rotating ring. One side of the irregularly shaped limiting block is provided with an arc-shaped surface, and an arc-shaped seat is fixedly connected to the upper surface of the protective cap. When the rotating ring rotates, the arc-shaped surface of the irregularly shaped limiting block can contact the arc-shaped seat, driving multiple locking rods to slide synchronously and insert into the corresponding locking holes, thereby realizing the rapid locking of multiple connecting plates.

[0011] Furthermore, a fixing seat 1 is fixedly connected to the outer wall of the rotating ring, and two fixing seats 2 are fixedly connected to the outer wall of the flange 2 respectively. Both fixing seats 1 and fixing seats 2 are provided with screw holes, and screws are threaded into the screw holes to lock the position of the rotating ring after rotation.

[0012] Furthermore, the arc-shaped surface is a smooth arc-shaped limiting surface.

[0013] Furthermore, both pipe one and pipe two have integrally formed sealing lips on opposite sides, the two sealing lips fit together, and a sealing ring is provided at the sealing groove of the sealing lip.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an adaptive sealing connection device for building pipeline installation, which has the following advantages:

[0016] 1. This utility model, by setting up a quick-locking component, an irregularly shaped limiting block, and a rotating ring, allows for simultaneous insertion of all locking rods into the corresponding locking holes of the connecting plates by simply rotating the rotating ring (angle ≤ 60°, time ≤ 10 seconds) during use. This achieves one-time locking of multiple connecting plates. Combined with the initial "connecting plate alignment and insertion" positioning method, the overall installation time is short, enabling rapid connection between two pipe fittings without tool dependence, lowering the operational threshold, and making it suitable for temporary use, frequent maintenance, space modification, emergency response, and other scenarios. It has good performance.

[0017] 2. In this utility model, the connection end of pipe one and pipe two forms a double seal through "sealing lip fitting + elastic sealing ring compression": the two sealing lips fit together to achieve a preliminary physical seal, and the sealing ring adapts to deformation under the fitting pressure, which can fill the small defects or gaps on the surface of the sealing lip, thus ensuring the sealing performance of the pipe connection and preventing leakage.

[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] Example

[0026] like Figure 1 , Figure 4 and Figure 5 As shown in the figure, an adaptive sealing connection device for building pipe installation proposed in one embodiment of the present invention includes a pipe 1 and a pipe 6. A flange 3 is fixedly connected to the outer wall of the pipe 1 near the pipe 6 by a support rod 2. A boss 4 with an annular cross section is integrally formed on one side of the flange 3. An array of connecting plates 5 are fixedly connected to the boss 4 near the pipe 6. A flange 7 is fixedly connected to the outer wall of the pipe 6 near the pipe 1 by a support rod 2. A boss 9 with an annular cross section is integrally formed on one side of the flange 7. A connecting hole 16 is opened on the boss 9 corresponding to the connecting plate 5, which penetrates the flange 7. The connecting hole 16 is adapted to the connecting plate 5. A quick locking component 8 is installed on the side of the boss 9 located at the connecting hole 16 to realize the locking and positioning of the connecting plate 5 after it is inserted into the connecting hole 16.

[0027] It should be noted that pipe 1 and pipe 6 serve as the main connecting components, and are fixed to flange 3 and flange 7 respectively by support rod 2. The rigid structure of support rod 2 can evenly transmit the radial force of the pipe to the flange. The boss 4 of flange 3 and the boss 9 of flange 7 are both annular structures, and the connecting plate 5 on boss 4 is adapted to the connecting hole 16 of boss 9, ensuring that pipe 1 and pipe 6 are coaxially aligned and preventing the connecting plate 5 from shifting when inserted into the connecting hole 16. When pipe 1 is pushed into pipe 6, the connecting plate 5 on boss 4 will be inserted along the connecting hole 16 of boss 9. The interference fit between the connecting plate 5 and the connecting hole 16 can achieve initial positioning and limit the radial displacement of the pipe. At this time, the quick-locking component 8 on boss 9 is in the "awaiting" state. After the connecting plate 5 is fully inserted (i.e., the sealing lip 14 is in contact), the quick-locking component 8 locks the connecting plate 5 through the mechanical structure, limiting the axial displacement of the pipe and finally achieving a stable connection between the two pipes.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the quick-locking component 8 includes a pad 801, which is fixedly connected to the outer wall of the second boss 9; a locking rod 802, which is slidably connected to the corresponding holes in the pad 801 and the second boss 9, and the connecting plate 5 is provided with a locking hole adapted to the locking rod 802, and the locking rod 802 is inserted into the locking hole to lock and fix the connecting plate 5; an arc-shaped protrusion 803, which is integrally formed on the lower end of the locking rod 802; a protective cap 805, which is fixedly connected to the upper end of the locking rod 802; and a spring 804, which is sleeved on the locking rod 802, and whose two ends abut against the pad 801 and the protective cap 805 respectively.

[0029] It should be noted that the pad 801 is fixed to the outer wall of the second boss 9 by welding, and its through hole is coaxial with the through hole of the second boss 9, providing a sliding guide for the locking rod 802, ensuring that the locking rod 802 can only move axially (avoiding radial offset that would prevent it from being inserted into the locking hole); the locking rod 802 is the core actuator. Under normal conditions, the spring 804 sleeved on the locking rod 802 is in a slightly compressed state. The elastic force of the spring 804 is transmitted to the locking rod 802 through the protective cap 805, causing the locking rod to... 802 maintains the "lifted and ready to be inserted" posture (the lower end of the locking rod 802 is flush with the inner wall of the second boss 9); when an external force (such as the extrusion of the irregularly shaped limiting block 10) pushes the protective cap 805 downward, the spring 804 is further compressed, the locking rod 802 slides downward along the through hole and inserts into the locking hole of the connecting plate 5, and the axial movement of the connecting plate 5 is restricted by the "rod-hole cooperation" to achieve locking; when the external force disappears, the spring 804 returns to its original position, pushes the locking rod 802 upward to disengage from the locking hole, and completes the unlocking.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a rotating ring 13 is rotatably connected to the side of flange 2 7 near pipe 1, and an array of irregularly shaped limiting blocks 10 are fixedly connected to the inner wall of the rotating ring 13. An arc-shaped surface 17 is provided on one side of the irregularly shaped limiting block 10, and an arc-shaped seat 806 is fixedly connected to the upper surface of the protective cap 805. When the rotating ring 13 rotates, the arc-shaped surface 17 of the irregularly shaped limiting block 10 can contact the arc-shaped seat 806, driving multiple locking rods 802 to slide synchronously and insert into the corresponding locking holes, thereby realizing the rapid locking of multiple connecting plates 5. The arc-shaped surface 17 is a smooth arc-shaped limiting surface.

[0031] It should be noted that the rotating ring 13 is rotatably connected to flange 7 via bearings and can rotate around the axis of flange 7. The irregularly shaped limiting block 10 on the inner wall of the rotating ring 13 rotates synchronously with the rotating ring 13. The arc-shaped surface 17 of the irregularly shaped limiting block 10 is a key transmission structure. The arc-shaped surface 17 adopts a smooth curved surface design, which can reduce the frictional resistance with the arc-shaped seat 806 on the protective cap 805. When the rotating ring 13 is rotated clockwise, the arc-shaped surface 17 of the irregularly shaped limiting block 10 gradually contacts the upper surface of the arc-shaped seat 806. As the rotating ring 13 continues to rotate, The arc-shaped surface 17 generates a tangential force on the arc-shaped seat 806. This force can be decomposed into a downward axial force and a horizontal radial force. The axial force pushes the arc-shaped seat 806 to move the protective cap 805 downward, thereby driving the locking rod 802 to insert into the locking hole. Since the irregularly shaped limiting blocks 10 are evenly distributed along the inner wall of the rotating ring 13, the squeezing force of all the arc-shaped surfaces 17 on the arc-shaped seat 806 is consistent and the action is synchronized, ensuring that multiple sets of locking rods 802 are inserted into the corresponding locking holes at the same time, resulting in high efficiency and good performance.

[0032] like Figure 1 As shown, in some embodiments, a fixing seat 11 is fixedly connected to the outer wall of the rotating ring 13, and two fixing seats 12 are fixedly connected to the outer wall of the flange 7 respectively. Both the fixing seat 11 and the fixing seat 12 are provided with screw holes, and screws are threaded to the screw holes to lock the position of the rotating ring 13 after rotation.

[0033] It should be noted that both the fixing seat 11 on the outer wall of the swivel ring 13 and the fixing seat 12 on the outer wall of the flange 7 have coaxial screw holes. When the swivel ring 13 rotates to the locked position, the screw hole of the fixing seat 11 is completely aligned with the screw hole of one of the fixing seats 12. At this time, the screw is inserted into the two screw holes and tightened to restrict the rotation of the swivel ring 13. If it is necessary to unlock, simply unscrew the screw, which is convenient and quick. In addition, two fixing seats 12 are provided on the flange 7, corresponding to the "locked position" and the "unlocked position" respectively. The rotation angle of the swivel ring 13 can be accurately positioned by the cooperation of the fixing seat 11 with different fixing seats 12.

[0034] like Figure 1 and Figure 5 As shown, in some embodiments, both pipe 1 and pipe 2 are integrally formed with sealing lips 14 on opposite sides, the two sealing lips 14 fit together, and a sealing ring 15 is provided at the sealing groove of the sealing lip 14.

[0035] It should be noted that when the two pipes are fully connected, the two sealing rings 15 are in full contact, forming a squeezing effect, which can prevent fluid leakage and play a role in leak protection.

[0036] The working principle and usage steps of this utility model are as follows: First, slowly push pipe 1 to fully insert the connecting plate 5 into the connecting hole 16 until the sealing lips 14 of the two pipes are tightly fitted, completing the initial positioning. Then, rotate the rotating ring 13 clockwise until the fixing seat 11 on the rotating ring 13 is aligned with the "locking position" fixing seat 12 of the flange 7. At this time, the arc-shaped surface 17 of the irregular limiting block 10 presses the arc-shaped seat 806, driving the locking rod 802 to insert into the locking hole of the connecting plate 5. Then, insert the screw into the screw hole of the fixing seat 11 and the corresponding fixing seat 12, tighten the screw to lock the rotating ring 13, and complete the installation. When disassembly and unlocking are required, unscrew the fixing screw, rotate the rotating ring 13 counterclockwise to the "unlocking position", the spring 804 resets and drives the locking rod 802 to disengage from the locking hole, canceling the locking effect. Then, pull out pipe 1 to disengage the connecting plate 5 from the connecting hole 16, and the disassembly is completed.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
