Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, specifically to a quick-installation pipe clamp. Background Technology

[0002] In the field of pipeline installation and maintenance, pipe clamps are an important connecting component and are widely used in various pipeline systems to fix and connect pipes, ensuring the sealing and stability of the pipeline system.

[0003] Traditional pipe clamps typically use a bolted connection method during installation, as shown in the reference. Figure 1 This connection method requires installers to use tools to tighten multiple bolts one by one, which is a cumbersome process and takes a long time. Especially in some complex installation environments, such as narrow pipe shafts or when working at heights, installers need to use both hands to operate the tools, which not only increases the difficulty of installation but may also lead to low installation efficiency due to space constraints and even pose certain safety hazards.

[0004] Furthermore, bolted connections have certain limitations in terms of load-bearing capacity. Since the connection between the clamp and the pipe relies entirely on the tightening force of the bolts, it is prone to misalignment or localized stress concentration when the pipe is subjected to internal fluid pressure or external vibrations. This not only affects the seal between the clamp and the pipe but may also cause the clamp connection to loosen, thereby affecting the normal operation of the entire pipeline system and even leading to safety accidents.

[0005] Meanwhile, the traditional all-bolted clamp structure is relatively complex, requiring additional bolts, nuts and other connecting parts. This not only increases the overall weight and volume of the clamp, but also makes the disassembly process of the clamp more troublesome and time-consuming during pipeline maintenance or replacement, and its reusability is affected to some extent. Utility Model Content

[0006] The purpose of this utility model is to propose a quick-installation pipe clamp, which can improve the installation efficiency and stability of the clamp.

[0007] To achieve the above objectives, this disclosure provides a quick-installation pipe clamp. The clamp body includes two symmetrical semi-circular retaining rings, namely a first retaining ring and a second retaining ring. The two ends of the clamp adopt a snap-fit ​​structure and a fastening connection structure, respectively. One end of the first retaining ring is provided with an arc-shaped buckle, and the corresponding end of the second retaining ring is provided with a cylindrical retaining shaft that matches the arc-shaped buckle. The buckle body extends towards the opposite side of the clamp's closing direction. The other end of the first retaining ring is provided with a first connecting ear, and the other end of the second retaining ring is provided with a second connecting ear. The first connecting ear and the second connecting ear are fastened together by a fastening assembly.

[0008] The beneficial effects of the basic design: The arc-shaped buckle of the first retaining ring and the cylindrical retaining shaft of the second retaining ring form a matching snap-fit ​​structure, and the buckle body extends to the opposite side of the clamp closing direction. During installation, simply align the buckle with the retaining shaft and push it along the clamp closing direction to quickly complete the snap-fit ​​positioning at one end, without the need for complex alignment or tool assistance, greatly shortening the installation time.

[0009] The snap-fit ​​process is more ergonomic, allowing the installer to push the snap ring with one hand to engage the snap pin, while the other end is secured by the fastening components, reducing the need for two hands and making it especially suitable for installation scenarios with limited space (such as narrow pipe shafts, high-altitude operations, etc.).

[0010] The buckle body extends to the opposite side of the clamp's closing direction. After the clamp closes, internal pipe pressure or external vibration will tighten the connection between the buckle and the clamp shaft (rather than loosen it). When the fluid pressure inside the pipe increases, the clamp experiences outward tension. At this time, the buckle body, due to its opposite extension design, will more firmly hook onto the clamp shaft, preventing one end of the clamp from loosening. The matching structure of the arc-shaped buckle and the cylindrical clamp shaft has a clear installation direction, avoiding connection failure due to incorrect installation. If the buckle is not correctly engaged with the clamp shaft, the clamp cannot close completely, which is visually apparent and can be corrected promptly, reducing safety hazards.

[0011] One end of the clamp uses a snap-fit ​​structure for quick positioning, while the other end is secured by a fastening connection component, forming a dual-support force mode with snap-fit ​​positioning at one end and rigid fastening at the other. This ensures that the clamp is subjected to uniform force in the circumferential direction, avoiding the skewing or localized stress concentration that may occur with a single fastening method (such as a full bolt connection), and improving the overall stability of the connection.

[0012] The snap-fit ​​design requires no additional connectors and is more compact than traditional bolted clamps. It allows for quick disassembly during pipe repair or replacement and offers high reusability.

[0013] As a feasible preferred option, the first retaining ring and the second retaining ring are made of plastic.

[0014] As a feasible preferred solution, the inner side of the buckle is provided with two opposing limiting protrusions.

[0015] As a feasible preferred solution, the surface of the limiting protrusion facing the inside of the buckle is an arc surface, with the same curvature as the buckle.

[0016] As a feasible preferred solution, the edge of the arc surface and the buckle connection is located at the perpendicular line from the geometric center of the buckle.

[0017] As a feasible preferred solution, the surface of the limiting protrusion facing the inside of the buckle is an inclined surface.

[0018] As a feasible preferred solution, the buckle and the snap pin are connected to the clamp body through an extension structure, and the extension structure is flush with the edge of the snap ring.

[0019] As a feasible preferred solution, the fastening assembly includes bolts and nuts, with corresponding screw holes at the center of the first connecting lug and the second connecting lug.

[0020] As a feasible preferred embodiment, the outer surface of the first or second retaining ring is further provided with a connection port structure, the connection port structure including an outer ring mounting seat and an inner ring screw seat, the outer ring mounting seat being used to install an external fixing component, and the inner ring screw seat being used to install a fixing screw.

[0026] To make the technical solution and advantages of this application clearer, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, and are only used to explain this application, not to limit it. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined with each other to achieve better technical effects. The same reference numerals appearing in the accompanying drawings of the following embodiments represent the same features or components, and can be applied to different embodiments.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection (including various forms of mechanical connection, such as couplings or gear pairs), or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Furthermore, unless otherwise defined, the technical or scientific terms used in this description shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings:

[0030] Reference numerals in the attached drawings: 1. First retaining ring; 2. Second retaining ring; 3. Buckle; 4. Restricting protrusion; 5. Extension structure; 6. First connecting ear; 7. Second connecting ear; 8. Connecting port structure; 9.

[0031] Reference Figure 2 This embodiment discloses a quick-installation pipe clamp. The clamp body includes two symmetrical semi-circular retaining rings, namely a first retaining ring 1 and a second retaining ring 1. The two ends of the clamp adopt a snap-fit ​​structure and a fastening connection structure, respectively.

[0032] The first retaining ring 1 and the second retaining ring 1 are preferably made of plastic, which has a certain degree of deformation capability.

[0033] Reference Figure 3 One end of the first retaining ring 1 is provided with a buckle 3, as shown in the reference. Figure 4 The second retaining ring 1 has a retaining shaft 4 that matches the buckle 3 at the corresponding end; the buckle 3 is arc-shaped and the retaining shaft 4 is cylindrical.

[0034] The buckle 3 extends to the opposite side of the clamp closing direction, forming a reverse snap-fit ​​structure with the clamp shaft 4.

[0035] During installation, first align the buckle 3 with the shaft 4 axially, and then rotate the first retaining ring 1 by about 90° to make the buckle 3 snap into the transverse groove of the shaft 4 to complete the initial fixation.

[0036] Reference Figure 3 The inner side of the buckle 3 is also provided with two opposing limiting protrusions 5. When the buckle 3 is engaged with the clip shaft 4, it can produce a certain deformation without hindering the engagement. After engagement, the limiting protrusions 5 can ensure the stability of the engagement structure.

[0037] The surface of the limiting protrusion 5 facing the inside of the buckle 3 is an arc surface with the same curvature as the buckle 3, which is also the same as the locking shaft 4, making it easy for the buckle 3 to rotate around the locking shaft 4 after it is engaged with the locking shaft 4. The edge of the arc surface where it connects with the buckle 3 is located at the perpendicular line from the geometric center of the buckle 3.

[0038] The surface of the limiting protrusion 5 facing the inside of the buckle 3 is inclined, which reduces the resistance of the buckle 3 when it is engaged with the buckle shaft 4, making the engagement operation easier and less strenuous.

[0039] The buckle 3 and the clamp shaft 4 are connected to the clamp body through the extension structure 6. The extension structure 6 is flush with the edge of the clamp ring. On the one hand, the extension structure 6 can ensure that the buckle 3 has enough space to rotate around the clamp shaft 4. On the other hand, after the buckle 3 and the extension structure 6 of the clamp shaft 4 are attached, the first clamp ring 1 and the second clamp ring 1 can form a ring, thus preventing the buckle 3 from rotating excessively.

[0040] Under the pressure inside the pipeline, the reverse snap-fit ​​structure can form a self-locking effect, significantly improving the resistance to vibration and loosening.

[0041] The other end of the first retaining ring 1 is provided with a first connecting lug 7, and the other end of the second retaining ring 1 is provided with a first connecting lug 8. The first connecting lug 7 and the first connecting lug 8 are pressed and fixed by a fastening assembly. In this embodiment, the fastening assembly includes a bolt and a nut. The first connecting lug 7 and the first connecting lug 8 are provided with corresponding screw holes at their centers. The first connecting lug 7 and the first connecting lug 8 can be fastened by the bolt and the nut that mates with the bolt.

[0042] When using this device, the first retaining ring 1 and the second retaining ring 1 are quickly snapped together by the snap-on structure 3, then put on the pipe, and finally tightened by the fastening connection structure. If the pressure is too high, the fastening components can be adjusted appropriately.

[0043] Example 2

[0044] The technical feature that distinguishes this embodiment from Embodiment 1 is that the outer surface of the first retaining ring 1 or the second retaining ring 1 is further provided with a connecting port structure 9, as shown in the figure. Figure 5 In this embodiment, the connection structure 9 is installed on the outer side of the second retaining ring 1. The connection structure 9 includes an outer ring mounting seat and an inner ring screw seat. The outer ring mounting seat is used to install the external fixing component, and the inner ring screw seat is used to install the fixing screw. The external fixing component can be used to support or lift the pipe.
