Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically to a pipe sleeve and its pipe rest installation structure. Background Technology

[0002] During pipeline construction and installation, the connection between pipe fittings and pipe supports is a crucial step in ensuring the stable and safe operation of the pipeline system. Pipe sleeves (clamps) are required at the end-to-end connections of pipe fittings. Traditional pipe sleeves are generally made of metal or plastic and are fixed by bolts, nuts, or clips, lacking self-locking functionality. Over time, they can loosen, affecting the sealing effect at the pipe fitting connection.

[0003] With modern pipeline engineering placing higher demands on the sealing, stability, and ease of installation of pipeline systems, especially in large pipeline systems that require high reliability and long-term stable operation, designing a more optimized, easier-to-install, and durable sealing pipe sleeve and pipe support installation structure has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe sleeve that can effectively improve the connection strength of pipe fittings, facilitate installation and disassembly, and provide better sealing and protection functions during application.

[0005] The technical solution adopted by this utility model to solve the above problems is: a sleeve, including a first sleeve and a second sleeve that are elastically hinged to each other by a hinge seat. Both the first sleeve and the second sleeve are semi-circular arc-shaped. The movable end of the first sleeve is provided with two sets of hole seats, and the hole seats are provided with through holes. The movable end of the second sleeve is provided with a connecting arm that matches the through holes. The connecting arm is provided with a barbed buckle. The hole seat is provided with a groove that matches the buckle.

[0006] Both the first and second card sleeves are equipped with pressing plates at their movable ends.

[0007] The pressing plate has a through hole, and the two sets of pressing plates can be fixed by bolts and nuts.

[0008] Preferably, both ends of the first and second card sleeves are provided with ferrules.

[0009] A pipe support installation structure includes the aforementioned pipe sleeve, pipe support plates symmetrically arranged at both ends of the pipe sleeve, and pipe fittings passing through the pipe support plates. The pipe support plates have pipe holes adapted to the pipe fittings. The pipe support plates include an upper plate and a lower plate that are detachably connected by a pin. The inner mating edges of the upper plate and the lower plate have inner mating pin holes adapted to the insertion of the pins.

[0010] Preferably, the pipe fitting includes two sets of corrugated pipes, with a sealing ring sleeved on the outer side of the connecting end of the corrugated pipe, and an annular groove adapted to the sealing ring is provided inside the pipe sleeve, with retaining edges provided at both ends of the annular groove.

[0011] Preferably, the tube pillow plate is provided with an arc-shaped tube pillow corner, a tube pillow edge, and a hole edge.

[0012] Preferably, the tube pillow has several pillow-side pin holes.

[0013] Preferably, the tube pillow plate is provided with tube pillow ribs, and the two ends of the tube pillow ribs are respectively connected and fixed to the inner edge and the hole edge.

[0014] Compared with the prior art, this utility model has the following advantages and effects:

[0015] This utility model's pipe sleeve adopts a self-locking structure, utilizing the cooperation of a barbed buckle and a groove to ensure a firm and secure connection, preventing loosening during long-term use and significantly improving the sealing and stability of the pipeline system.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] Example 1:

[0025] See Figure 1 and Figure 2 In this embodiment, a pipe sleeve 1 is specifically used for connecting and sealing pipe fittings 32 in a piping system. The pipe sleeve 1 in this embodiment includes a first clamping sleeve 12 and a second clamping sleeve 13 that are elastically hinged to each other by a hinge seat 11. Both the first clamping sleeve 12 and the second clamping sleeve 13 are semi-circular arc-shaped. The movable end of the first clamping sleeve 12 is provided with two sets of hole seats 14, and the hole seats 14 are provided with through holes 15. The movable end of the second clamping sleeve 13 is provided with a connecting arm 16 that is adapted to the through holes 15. The connecting arm 16 is provided with a barbed buckle 17. The hole seats 14 are provided with a groove 18 that is adapted to engage with the buckle 17.

[0026] Specifically, in this embodiment, the sleeve 1 is made of plastic materials such as PVC, PP, and PE. These materials have good corrosion resistance, toughness, and elasticity, and can maintain long-term stable performance in various environments. Its hinge seat 11 has an elastic restoring force that allows the first retaining sleeve 12 and the second retaining sleeve 13 to open. The buckle 17 is hidden and elastically connected to the end of the connecting arm 16 (this can be achieved through a torsion spring or the elasticity of the plastic part itself). During the process of inserting the connecting arm 16 into the through hole 15 of the hole seat 14, the buckle 17 retracts after being squeezed. Once the buckle 17 has completely passed through the hole seat 14, it springs outward under the action of elastic force or manual levering. The elastic force of the hinge seat 11 will drive the first retaining sleeve 12 and the second retaining sleeve 13 to open, causing the connecting arm 16 to be pulled out of the hole seat 14. Since the buckle 17 has already popped open at this time, when the connecting arm 16 is pre-pulled out, the end of the buckle 17 will naturally insert into the slot 18 of the hole seat 14, forming a self-locking mechanism to prevent the connecting arm 16 from being pulled out further, thereby ensuring that the connection between the fitting 32 and the sleeve 1 is firm and reliable.

[0027] Furthermore, both the first ferrule 12 and the second ferrule 13 are equipped with pressing plates 21 at their movable ends. During installation, the pressing plates 21 can be pressed with fingers in the direction of their closing, providing additional leverage points and making it easier for the connecting arm 16 to pass through the through hole 15 of the socket 14, thus reducing the difficulty of installation. This helps users complete the installation work in limited spaces (e.g., small and deep trenches for buried pipes).

[0028] The pressing plate 21 has through holes 22, and two sets of pressing plates 21 can be fixed by bolts 23 and nuts 24. Specifically, after the bolts 23 pass through the through holes 22 of the two sets of pressing plates 21 in sequence, the other end is tightened by nuts 24, thereby further enhancing the pressure between the two sets of pressing plates 21 and ensuring that the buckle 17 can more stably cooperate with the hole seat 14. In this embodiment, the bolts 23 and nuts 24 are used to reinforce the connection between the first clamping sleeve 12 and the second clamping sleeve 13, which further enhances the connection strength between the sleeve 1 and the fitting 32, and is particularly suitable for pipeline systems in high-pressure and high-vibration environments.

[0029] Both ends of the first sleeve 12 and the second sleeve 13 are provided with sleeve edges 25. In this embodiment, the sleeve 1 adopts an extended sleeve edge 25 design, which can increase the structural strength of the end of the sleeve 1 and make it less prone to damage. On the other hand, it can block some dust after the subsequent installation of the pipe fitting 32, improve the sealing effect of the connection inside the sleeve 1, and reduce the contamination of the connection part.

[0030] Example 2:

[0031] See Figures 3-6 This embodiment provides a pipe support installation structure, including the pipe sleeve 1 described in Embodiment 1, pipe support plates 31 symmetrically arranged at both ends of the pipe sleeve 1, and pipe fittings 32 passing through the pipe support plates 31. The pipe support plates 31 have pipe holes 33 adapted to the pipe fittings 32, and are composed of an upper fitting plate 35 and a lower fitting plate 36 detachably connected by pins 34. The inner mating edges of the upper fitting plate 35 and the lower fitting plate 36 have inner mating pin holes 37 adapted to the insertion of the pins 34. During installation, the pipe support plates 31 are first laid with the notch of the lower fitting plate 36 facing upwards below the pipe fitting 32, and then the upper fitting plate 35 is fastened above the pipe fitting 32, so that the inner mating edges of the upper fitting plate 35 and the lower fitting plate 36 contact and assemble. Then, both ends of the pins 34 are inserted into the inner mating pin holes 37 of the upper fitting plate 35 and the lower fitting plate 36, respectively. After the two sets of pipe support plates 31 are installed, the pipe body is erected, and the pipe sleeve 1 is located between the two sets of pipe support plates 31. In this embodiment, the pipe support can be made of materials such as steel or fiberglass, and its structural strength is much higher than that of the pipe sleeve 1, thus providing effective protection for the pipe sleeve 1 located in the middle.

[0032] See Figure 3The pipe fitting 32 includes two sets of corrugated pipes 41. Because the corrugated pipes 41 are flexible and can expand and deform, they are more flexible than conventional pipes, thus requiring higher sealing performance at their connections. In this embodiment, a sealing ring 42 is fitted around the connecting end of the corrugated pipe 41 (the connecting end has no corrugated structure). An annular groove 43, adapted to the sealing ring 42, is provided inside the pipe sleeve 1, with retaining edges 44 at both ends of the annular groove 43. The sealing ring 42 effectively seals the connecting end of the corrugated pipe 41 within the pipe sleeve 1, preventing external contaminants from entering the pipe fitting 32 and ensuring the stability and durability of the connection between the pipe fitting 32 and the pipe sleeve 1. The annular groove 43 prevents the sealing ring 42 from shifting or falling off during use, ensuring that the plane of the pipe support plate 31 fits snugly against the end face of the pipe sleeve 1, further improving the sealing effect at the connection.

[0033] See Figure 4 The pipe rest plate 31 is provided with an arc-shaped pipe rest angle 45, a pipe rest edge 46, and a hole edge 47. The pipe rest angle 45 adopts an arc-shaped structure to distribute the pressure it bears, reduce local stress concentration, and improve the overall stability of the pipe rest. The pipe rest edge 46 is used to form a relatively neat array of pipe fittings 32 when more pipe fittings 32 are arranged in the same direction, see [link to relevant documentation]. Figure 5 The design of the hole edge 47 increases the structural strength of the pipe hole 33 and also increases the contact area between the pipe hole 33 and the pipe fitting 32, thereby reducing the contact stress between the pipe hole 33 and the pipe fitting 32 and improving the service life of the pipe fitting 32. The pipe pillow edge 46 has several pillow edge pin holes 48. These pin holes 48 can be used to place pins 34 for connection and fixation between adjacent pipe pillow plates 31, allowing for the installation of a larger number of pipe fittings 32 as needed. (See [reference]). Figure 6 .

[0034] The tube rest plate 31 is provided with tube rest ribs 49, and the two ends of the tube rest ribs 49 are respectively connected and fixed to the inner edge and the hole edge 47. As a reinforcing structure of the tube rest plate 31, the tube rest ribs 49 can effectively enhance the overall rigidity and stability of the tube rest plate 31. When the tube rest plate 31 is under stress, it can share part of the pressure and prevent the tube rest plate 31 from deforming and cracking due to excessive stress.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
