Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to an anti-twist type galvanized pipe splicing sleeve. Background Art

[0002] In the construction, industrial, and municipal construction sectors, piping systems are essential for transporting fluids or gases. Traditional pipe connections typically utilize flanges, welding, or threaded connections. While these methods can meet basic connection requirements, hot-dip galvanized steel pipes are buried in building floors and used for subsequent wiring and cable routing. Common connection methods include butt welding or wrapping with large-sized pipe sleeves.

[0003] Under certain load scenarios, such as wind loads or mechanical vibration, traditional pipe connections are prone to twisting, causing the connection to loosen or even leak. This twisting not only affects the normal operation of the system but can also pose serious safety hazards. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-twist galvanized pipe splicing sleeve to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-twist galvanized pipe splicing sleeve, comprising:

[0006] Galvanized pipe fittings are arranged symmetrically up and down;

[0007] The anti-twist splicing assembly includes a splicing sleeve that is sleeved on the opposite ends of two galvanized pipe fittings and U-shaped limit clamps symmetrically welded to the upper and lower outer walls of the splicing sleeve fittings, with the receiving end of each U-shaped limit clamp facing the adjacent galvanized pipe fitting;

[0008] The two U-shaped limit clamps are symmetrically welded to the outer walls of the opposite ends of the two U-shaped limit clamps. The limit clamps are clamped into the adjacent U-shaped limit clamps and locked together by means of a limit pin. The interior of the splicing sleeve is also provided with an elastic and detachable lock assembly for locking the galvanized pipe fittings. When the two galvanized pipe fittings are relatively inserted into the splicing sleeve, the limit clamps of the U-shaped limit clamps are clamped into the U-shaped limit clamps and locked by means of the limit pin. This not only achieves an anti-twist effect, but also serves as a positioning function during installation, preventing misalignment and jamming during installation.

[0009] Preferably, the outer walls on both sides of each U-shaped limiting clamp are symmetrically provided with limiting lock holes, and the limiting lock holes are used for plugging and installing the limiting pin shaft.

[0010] Preferably, in this solution, a splicing recess is provided in the middle of the peripheral outer wall of the splicing sleeve, and the splicing recess is provided to protrude toward the inner cavity of the splicing sleeve.

[0011] Preferably, an inner sleeve is provided in both ends of the inner cavity of the splicing sleeve, and a plurality of embedded grooves are provided in an annular array symmetrically and equidistantly on the inner walls of both ends of the splicing sleeve.

[0012] Preferably, in this solution, the inner wall of each inner sleeve is provided with a plurality of through holes in a vertically symmetrical annular array, and each through hole is aligned with each embedded groove.

[0013] Preferably, the elastically detachable locking assembly includes an elastic member bonded to the inner wall of each embedded groove and a limiting locking steel ball embedded in the embedded groove and abutting against the elastic member.

[0014] Preferably, in this solution, when the limiting lock steel ball is embedded in the embedded groove and abuts against the elastic part, the inner liner sleeve is inserted into the splicing sleeve and welded together, so that the limiting lock steel ball in the embedded groove protrudes from the through hole in the inner liner sleeve.

[0015] Preferably, in this solution, the outer wall of one end of each galvanized pipe fitting close to the spliced ​​sleeve fitting is provided with a plurality of lock holes in a vertically symmetrical annular array for accommodating the protruding parts of the limit lock steel balls.

[0016] Preferably, when the galvanized pipe is inserted into the splicing sleeve, the limit lock steel ball in the splicing sleeve abuts against the lock hole due to the elastic force of the elastic member, thereby facilitating the insertion and removal of the splicing sleeve and helping to lock them together.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] This anti-twist galvanized pipe splicing sleeve features symmetrically welded U-shaped limit clamps on the upper and lower outer walls of the splicing sleeve. Limiting blocks are positioned on the outer walls of the opposite ends of each U-shaped limit clamp. These limit clamps engage with each other and are locked together via a limit pin. This design effectively prevents relative rotation between the two galvanized pipes after connection, thereby ensuring the stability and safety of the piping system.

[0019] When two galvanized pipes are inserted into the splicing sleeve, the U-shaped limit plate and limit block design help operators more easily align and lock the pipes together, reducing the risk of misalignment and jamming, and improving installation efficiency. It not only provides anti-twist function, but also plays a role in positioning during installation.

[0020] The splicing sleeve is equipped with a resilient, removable locking assembly, including an elastic element and a retaining locking steel ball. When the galvanized pipe is inserted into the splicing sleeve, these components automatically pop out and lock, providing additional mechanical connection force, enhancing the strength and stability of the overall connection.

[0030] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0032] This embodiment provides Figures 1 to 6 As shown in 1, an anti-twist galvanized pipe splicing sleeve includes: a galvanized pipe fitting 1 and an anti-twist splicing assembly 4.

[0033] In this embodiment, galvanized pipe fittings 1 are arranged symmetrically in a vertical arrangement. They serve as the primary piping component for conveying fluids or gases. They provide a corrosion-resistant base pipe, which can be spliced ​​to extend the length or connect different pipe sections, ensuring the continuity and durability of the piping system.

[0034] In this embodiment, the anti-twist splicing assembly 4 comprises a splicing sleeve 2 that fits over the opposing ends of two galvanized pipes 1, and U-shaped retaining clips 6 symmetrically welded to the upper and lower outer walls of the splicing sleeve 2. The receiving end of each U-shaped retaining clip 6 faces the adjacent galvanized pipe 1. The splicing sleeve 2 serves as a connector between the two galvanized pipes 1, allowing for a quick and secure connection between the galvanized pipes 1 while preventing twisting through internal components. This enables rapid installation and removal of the piping system while improving overall structural stability.

[0035] In this embodiment, two U-shaped limit clamps 6 are symmetrically welded to their outer walls at opposite ends. The limit clamps 9 are engaged with adjacent U-shaped limit clamps 6 and locked together via a limit pin 10. The interior of the splicing sleeve 2 is also provided with an elastic, detachable locking assembly for locking the galvanized pipe fittings 1. When the two galvanized pipe fittings 1 are relatively inserted into the splicing sleeve 2, the limit clamps 9 of the U-shaped limit clamps 6 are engaged with the U-shaped limit clamps 6 and locked via the limit pin 10. This not only achieves an anti-twist effect, but also serves as a positioning function during installation, preventing misalignment and jamming during insertion and installation. The limit pin 10 is inserted into the limit lock hole 7 to secure the U-shaped limit clamps 6. As a locking element, it prevents the U-shaped limit clamps 6 from moving relative to the splicing sleeve 2. This ensures the effective implementation of the anti-twist function and improves the stability of the pipeline connection.

[0036] In this embodiment, the outer walls on both sides of each U-shaped limit card plate 6 are symmetrically provided with limit lock holes 7, and the limit lock holes 7 are provided for the plug-in installation of the limit pin 10. The U-shaped limit card plate 6 limits the position of the galvanized pipe fitting 1 during connection. Cooperating with the limit card block 9 and the limit pin 10, a locking mechanism is formed to prevent the pipes from rotating relative to each other. The stability of the pipe connection is ensured, and leakage or other problems caused by torsion are avoided. The limit card block 9 cooperates with the limit lock hole 7 on the U-shaped limit card plate 6 to limit the movement of the U-shaped limit card plate 6. By cooperating with the limit pin 10, a stable locking structure is formed. Accidental displacement of the U-shaped limit card plate 6 is prevented, and the anti-twisting effect is further enhanced.

[0037] In this embodiment, a splicing recess 3 is provided in the middle of the outer wall of the splicing sleeve 2. The splicing recess 3 projects into the inner cavity of the splicing sleeve 2. This splicing recess 3 enhances the structural strength of the splicing sleeve 2 and aids in positioning. It provides an additional contact surface, helps distribute stress, and also provides a mounting location for other components. This enhances the compressive strength and anti-slip properties of the splicing area.

[0038] In this embodiment, inner sleeves 5 are provided in both ends of the inner cavity of the splicing sleeve member 2, and multiple embedded grooves 11 are formed in an annular array symmetrically and equidistantly on the inner walls of both ends of the splicing sleeve member 2.

[0039] In this embodiment, the inner wall of each inner liner sleeve 5 is provided with a plurality of through-holes 12 in a vertically symmetrical annular array. Each through-hole 12 is aligned with a corresponding inner recess 11. The inner recess 11 accommodates an elastic member 13 and a retaining locking steel ball 8. This provides space for the elastic member 13 and the retaining locking steel ball 8 to function properly, supporting the locking mechanism and ensuring a secure connection.

[0040] In this embodiment, the resilient, removable locking assembly includes an elastic member 13 bonded to the inner wall of each recess 11, and a retaining locking steel ball 8 embedded in the recess 11 and abutting against the elastic member 13. The retaining locking steel ball 8 serves as part of the locking mechanism, working in conjunction with the elastic member 13. When the galvanized pipe 1 is inserted into the splicing sleeve 2, the elastic member 13 ejects it into the locking hole 14, locking the galvanized pipe 1 in place. This simplifies the installation process while ensuring a secure and reliable connection.

[0041] In this embodiment, when the retaining locking bead 8 is embedded in the internal groove 11 and abuts the elastic member 13, the inner sleeve 5 is inserted into the splicing sleeve 2 and welded together, causing the retaining locking bead 8 in the internal groove 11 to protrude from the through hole 12 in the inner sleeve 5. The inner sleeve 5 is located inside the splicing sleeve 2 to reinforce the connection. It provides additional support to help maintain the alignment of the galvanized pipe 1 and works in conjunction with the elastic detachable locking assembly, enhancing the sealing and structural integrity of the connection point.

[0042] In this embodiment, a plurality of locking holes 14 for accommodating the protruding parts of the limiting locking steel balls 8 are provided in a vertically symmetrical annular array on the outer wall of one end of each galvanized pipe fitting 1 close to the splicing sleeve fitting 2 .

[0043] In this embodiment, when the galvanized pipe fitting 1 is inserted into the splicing sleeve fitting 2, the limit lock steel ball 8 in the splicing sleeve fitting 2 is abutted against the lock hole 14 by the elastic force of the elastic member 13. This facilitates the insertion and removal of the splicing sleeve fitting 2 and helps to lock them together. The elastic member 13 is a silicone elastic block, and the elastic member 13 provides elastic force for the limit lock steel ball 8. Push the limit lock steel ball 8 into the lock hole 14 and provide sufficient rebound force when disassembly is required. This simplifies the installation and disassembly process while ensuring the tightness of the connection point.

[0044] Working principle:

[0045] The anti-twist galvanized pipe splicing sleeve aligns the two galvanized pipe fittings 1 to be connected with the two ends of the splicing sleeve 2. The U-shaped limit clamp 6 has been welded to the upper and lower outer walls of the splicing sleeve 2 to ensure that its accommodating end faces the galvanized pipe fitting 1 to be inserted, ready for the next operation. Find the pre-opened limit lock holes 7 on the outer walls on both sides of the U-shaped limit clamp 6. Insert the limit pin 10 into the corresponding limit lock hole 7 to fix the position of the U-shaped limit clamp 6 and prepare to cooperate with the limit block 9 on the other U-shaped limit clamp 6. Slowly insert one end of a galvanized pipe fitting 1 into the inner cavity of one end of the splicing sleeve 2. When the galvanized pipe fitting 1 contacts the inner sleeve 5, the limit lock steel ball 8 in the inner sleeve 5 is squeezed and retracted into the embedded groove 11. At this time, a certain pressure is maintained by the action of the elastic member 13. Continue to push the galvanized pipe fitting 1 until it completely enters the splicing sleeve fitting 2 , so that the locking hole 14 on the galvanized pipe fitting 1 is aligned with the limiting locking steel ball 8 in the embedded groove 11 .

[0046] Once the locking hole 14 on the galvanized pipe fitting 1 is aligned with the locking ball 8, the locking ball 8 is ejected by the elastic member 13, passes through the through hole 12, and engages in the locking hole 14. This completes the locking of the first galvanized pipe fitting 1. Repeat the above steps for the galvanized pipe fitting 1 on the other side, inserting it into the other end of the splicing sleeve 2 to complete the locking.

[0047] Check that both galvanized pipes 1 are securely locked within the splicing sleeve 2, ensuring there is no looseness or misalignment. If further reinforcement is required, the connection between the U-shaped retaining plate 6 and the splicing sleeve 2 can be strengthened by welding or other means. Once the entire splicing system is confirmed to be stable and reliable, the connection between the galvanized pipes 1 is complete.

[0048] At this time, the splicing sleeve 2 not only provides a physical connection, but also prevents relative rotation between pipes through the anti-torsion design, thereby ensuring the stability and safety of the system.
