Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, specifically a water supply and drainage connection device. Background Technology

[0002] Water supply and drainage pipeline engineering is an integral part of the water supply and drainage system and plays an important role in the entire system. It includes the pipeline system itself and various structures on the pipeline system. During the construction of water supply and drainage projects, it is often necessary to lay water supply and drainage pipelines.

[0003] Existing technology, patent document CN215568635U, provides a water supply and drainage pipeline connection device, including a first pipe and a second pipe. The first pipe includes a pipe body, one end of which has an annular portion. A first threaded connection portion is provided on one side of the annular portion, and the first threaded connection portion has an inner cavity. The second pipe is located at the end of the first threaded connection portion, and has a second threaded connection portion. A fixing sleeve is provided on both the first and second threaded connection portions, and the fixing sleeve has an internal thread. This utility model provides a stable connection for water supply and drainage pipelines, ensuring good sealing and allowing stable water flow within the pipes.

[0004] Although the device has many beneficial effects, the following problems still exist: The device uses threaded connection to the supply and discharge pipeline. Although an anti-loosening snap ring is added, the fixing sleeve still needs to be completely unscrewed along the thread to be disassembled. For occasions that require frequent maintenance, the operation efficiency is low and the time consumption is long.

[0005] Secondly, the rigid connection structure of this device lacks elastic buffering, and pipeline vibration can easily lead to fatigue failure of the sealing ring. Long-term operation may result in wear and leakage of the sealing surface. Utility Model Content

[0043] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0044] This utility model provides an overall structural diagram of an embodiment of a water supply and drainage connection device, including:

[0045] Please see Figures 1-6 A water supply and drainage connection device according to this embodiment includes: pipe a1 and pipe b2, with the connecting end of pipe b2 disposed at the connecting end of pipe a1;

[0046] Multiple connectors 10 are provided, some of which are threaded to the mating end of pipe a1 and others are threaded to the mating end of pipe b2. One end of some connectors 10 is welded with a snap-fit ​​sleeve 11, and the other end of some connectors 10 is welded with a mating sleeve 12. The mating sleeve 12 is tenon-tenoned to the outer periphery of the snap-fit ​​sleeve 11. Multiple connecting mechanisms 100 are provided at the connection between the snap-fit ​​sleeve 11 and the mating sleeve 12. The connecting mechanisms 100 can quickly remove the mating sleeve 12 from the snap-fit ​​sleeve 11.

[0047] The buffer mechanism 200 is located on the outer end of the snap-fit ​​sleeve 11.

[0048] It is worth noting that, in order to connect pipe a1 and pipe b2, specifically, the connecting mechanism 100 includes: a groove 101, which is formed on the outer periphery of the snap-fit ​​sleeve 11;

[0049] One end of the damping spring shock absorber a102 is welded into the groove 101, and the other end of the damping spring shock absorber a102 is welded to the limit block 103.

[0050] The limiting groove 104 is formed on the inner circumference of the mating sleeve 12. The limiting block 103 and the limiting groove 104 are interlocked to make the interlocking sleeve 11 and the mating sleeve 12 mortise and tenon jointed.

[0051] Next, in order to quickly disassemble the docking sleeve 12 and the snap-fit ​​sleeve 11, specifically, one end of the limiting block 103 is machined with a spherical surface 105, the other end of the limiting block 103 is machined with a plate surface 106, one end of the limiting groove 104 is provided with a spherical groove 107, and the other end of the limiting groove 104 is provided with a straight groove 108. The straight groove 108 and the plate surface 106 are interlocked with each other so that the spherical surface 105 and the spherical groove 107 can be quickly interlocked when the docking sleeve 12 and the snap-fit ​​sleeve 11 are installed.

[0052] Meanwhile, in order to buffer the vibration of pipe a1 and pipe b2, specifically, the buffer mechanism 200 includes: a base plate 201, which contacts the outer end of the snap sleeve 11, and a plurality of sliding grooves 202 are provided on the base plate 201.

[0053] Multiple limiting rods 203 are slidably connected at one end in the slide groove 202 to limit the filter screen 204. The filter screen 204 is welded to the other end of the multiple limiting rods 203 so that the water flow in pipe a1 and pipe b2 can impact the filter screen 204, reducing the impact of the water flow on the inner wall of pipe a1 and pipe b2.

[0054] Multiple damping spring shock absorbers b205 are welded to the base plate 201 at one end and to the filter screen 204 at the other end.

[0055] Furthermore, for disassembly and maintenance, specifically, a mounting plate 206 is welded to the outer periphery of the base plate 201, and the filter screen 204 is slidably connected to the inner periphery of the mounting plate 206. A threaded groove 207 is opened on the outer periphery of the mounting plate 206, and an internal thread 208 is welded to the inner wall of the outer end of the snap sleeve 11. The threaded groove 207 and the internal thread 208 can be threadedly connected.

[0056] It is worth noting that, specifically, for sealing purposes, a sealing ring 13 is bonded to the connection between the mating sleeve 12 and part of the connecting seat 10.

[0057] Finally, in order to install the connector 10, specifically, multiple connectors 10 have snap-fit ​​plates 14 welded to their other ends, and pipes a1 and b2 have mating grooves 15, and the snap-fit ​​plates 14 and mating grooves 15 can be threaded together.

[0058] Combination Figures 1-6 The water supply and drainage connection device of this embodiment is used in the following specific process:

[0059] 1. According to the actual use, thread the snap-fit ​​plate 14 and the mating groove 15 to install the connecting seat 10 on the mating end of pipe a1 and pipe b2. Adhere the sealing ring 13 to the bottom end of the snap-fit ​​sleeve 11. Align the snap-fit ​​sleeve 11 and the mating sleeve 12. Insert the snap-fit ​​sleeve 11 into the mating sleeve 12. The spherical surface 105 of the limiting block 103 is squeezed by the inner wall of the mating sleeve 12. The damping spring damper a102 contracts. When the mating sleeve 12 contacts the sealing ring 13, it stops. Rotate the mating sleeve 12 so that the limiting block 103 enters the limiting groove 104. The damping spring damper a102 rebounds.

[0060] 2: The water flow in pipes a1 and b2 impacts the filter screen 204, causing the damping spring shock absorber b205 to deform, which in turn causes the filter screen 204 to vibrate, thus converting the impact of the water flow on pipes a1 and b2 into the vibration of the filter screen 204.

[0061] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
