Description

Technical Field

[0001] This utility model relates to a pipe clamp, and more particularly to a thickened, anti-breakage PE pipe clamp. Background Technology

[0002] Pipe clamps are a common type of pipe fitting used in installation. During the construction of building drainage pipes, especially risers, pipe clamps are typically used to fix the risers to the wall to prevent them from shaking. The traditional solution is to use common, ordinary pipe clamps and screw them on with bolts to secure the risers. However, these ordinary pipe clamps have insufficient stability during construction because the wall thickness at right-angle connections is relatively thin. Workers often experience pipe clamp breakage when tightening the bolts. Furthermore, in confined spaces, nuts are difficult to secure and prone to falling off, making bolt tightening a challenging operation.

[0003] For example, a patent disclosed in Chinese patent literature, namely a plastic drain pipe clamp, with publication number CN219159720U, relates to a pipe clamp for pipe installation, including a clamp, a threaded sleeve, and a nail. The clamp is used to clamp the pipe, and the nail is used to fix the threaded sleeve to the base. The threaded sleeve has a through hole in the inside and an external thread on the outer circle for screwing the clamp. The connection of this pipe clamp is relatively thin and easy to break, and the nut needs to be fixed by hand during installation. Utility Model Content

[0004] This utility model aims to solve the problems of poor installation stability, difficulty in operation, and easy fall-off of pipe clamp nuts. A thickened pipe clamp that is less prone to breakage is designed. To achieve the above objectives, this utility model provides the following technical solution:

[0005] A thickened, fracture-resistant PE pipe clamp includes an upper clamp and a lower clamp, which are connected by bolts and nuts. Bolt holes and nut holes are designed at the right-angle connection point of the upper and lower clamps. The upper and lower clamps are connected by a through hole, and the right-angle connection point adopts a stepped structure. Compared to directly connecting with bolts and nuts, the stepped hole design increases the thickness of the connection point, allowing for thickening and concealing the bolts and nuts, reducing the impact of external forces on its stability.

[0006] The system uses a nut and bolt connection method, and during construction, the bolts can be tightened directly on the outside of the pipe clamp with a Phillips screwdriver, without the need to use a wrench to tighten the pipe clamp nuts on the inside. This makes installation convenient and quick, greatly improving construction efficiency.

[0007] By installing reinforcing ribs inside the nut hole, the pipe clamp nut can be embedded in the nut hole without moving, making it more secure and less likely to fall off even when directly screwed in with a wrench.

[0008] Pipe clamps with upper and lower clamps can be placed on the pipe according to its actual position during installation. The clamps are then fixed in place using pipe clamp bolts and nuts, making the water pipe more stable and preventing it from loosening due to external forces during use.

[0009] The pipe clamp is designed with an internal thread at the connector below it, and reinforcing ribs on both sides of the connector. The pipe clamp head is machined with an external thread and is tightly connected with the pipe clamp nut. This design secures the water pipe and then fixes the pipe clamp to the wall, making the pipe more stable and reducing loosening caused by external forces.

[0010] As a preferred option, an internal reinforcing rib is provided inside the nut hole so that the pipe clamp nut can be fixed inside the nut hole after it is inserted.

[0011] Preferably, the pipe clamp includes an upper clamp and a lower clamp, and the upper and lower clamps have an arc-shaped structure, which can better fit the water pipe. At the same time, reinforcing ribs are added inside the clamp structure. The arc-shaped structure of the upper and lower clamps fits the pipe, which can make the clamp and the pipe in close contact, ensuring the stability of the pipe inside the pipe clamp and preventing the pipe clamp from loosening due to long-term external force.

[0012] Preferably, the bolt holes at both ends of the upper clamp and the nut holes at both ends of the lower clamp form a stepped through hole. Compared with directly screwing in the nut bolt, the stepped hole design, through the positioning of the nut hole, ensures that the pipe clamp nut will not rotate when the pipe clamp bolt is screwed in, and can be hidden when fully tightened.

[0013] Preferably, the stepped holes on both sides of the upper and lower clamps increase the thickness of the connection at both ends. These stepped holes allow the nuts and bolts to be embedded within them, concealing them and protecting them from external forces, thus providing a protective function. They also ensure a tight connection and increase the wall thickness at the connection, enhancing its stability. Of course, the hole design is not limited to stepped holes; it can also be a round hole or other hole-like structure that allows the nuts and bolts to be embedded.

[0014] As a preferred option, the upper and lower clamps are connected by nuts and bolts for positioning and installation. At the same time, two reinforcing ribs are added inside the clamps to increase the thickness of the inner wall of the pipe clamp, which can better fit the water pipe, making the pipe clamp more stable and less prone to loosening, thus ensuring the stability of the pipe inside the pipe clamp.

[0015] Preferably, the bolt and nut are connected to the upper and lower clamps, and the stepped structure of the nut hole and bolt hole is the same size as the nut and bolt, which can achieve better positioning and prevent misalignment of the upper and lower clamps.

[0016] Preferably, a connector is installed below the lower clamp, with reinforcing ribs on both sides to enhance the stability of the lower clamp. Internal threads are machined on the inside of the connector, and external threads are machined on the pipe clamp head. A nut is used to connect and fix the pipe clamp to the connector. The pipe clamp can be driven into the wall, better securing the pipe to the wall and increasing the pipe's stability.

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

[0018] The use of internal reinforcing ribs allows the nut to be directly fixed into the nut hole during operation without needing to hold it down by hand, making it more convenient.

[0019] By utilizing stepped through holes, compared to directly screwing in a nut or bolt, the positioning of the nut hole prevents the pipe clamp nut from rotating when the pipe clamp bolt is screwed in.

[0020] By using stepped through holes, the thickness at the joint is increased, making the connection more stable;

[0021] During construction, bolts can be tightened directly on the outside of the pipe clamp with a Phillips screwdriver, without the need to use a wrench to tighten the nuts on the inside, making installation convenient and quick.

[0022] Adding reinforcing ribs to the clamps makes the pipe clamps fit more tightly and securely.

[0023] A connector is installed below the lower clamp, with reinforcing ribs on both sides of the connector, a pipe clamp, and a nut to secure the pipe clamp, making it more stable than a nail gun. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] To address the aforementioned issues, a thickened, less prone to breakage, and easy-to-install PE pipe clamp has been designed. This provides a solution for thickened, breakage-resistant PE pipe clamp technology. By improving the structural design of the pipe material, the performance of the PE pipe clamp is enhanced, reducing the risk of breakage during construction and use, and improving the reliability and service life of the PE pipe clamp.

[0032] A thickened and less prone-to-break pipe clamp features a connector under the lower clamp, with reinforcing ribs on both sides of the connector. The pipe clamp nail connects to the connector via a nail nut, securing the PE pipe clamp to the wall without wobbling. Reinforcing ribs are designed inside both the upper and lower clamps to increase the clamp's strength. Bolt holes are designed on both sides of the upper clamp, and nut holes are designed on both sides of the lower clamp. The through-hole formed by the bolt holes and nut holes is stepped. Reinforcing ribs are designed inside the nut holes to allow the nut to be inserted and fixed. The bolt holes and nut holes are the same size as the bolt heads of the pipe clamp, and the nut holes are the same size as the nut of the pipe clamp, allowing the bolt and nut to fit perfectly into the holes.

[0033] The design of the reinforcing ribs inside the nut hole is intended to secure the nut during insertion, thereby improving the load-bearing capacity of the connector and the overall rigidity of the structure. The following are some key steps and factors to consider when designing reinforcing ribs:

[0034] Analyzing the structural stress, reinforcing ribs need to be added inside the nut holes to improve local strength. Based on the shape and size of the nut holes, a suitable reinforcing rib shape should be designed, such as round, square, or irregularly shaped ribs. The dimensions of the reinforcing ribs, including thickness, width, and length, should be determined to ensure they provide sufficient support. Material selection: Choose a reinforcing rib material that matches the material of the nut holes to ensure good bonding strength and corrosion resistance.

[0035] Determine the optimal position of the reinforcing rib within the nut hole to maximize its supporting effect. Design the connection method between the reinforcing rib and the nut hole, which can be welding, bonding, or mechanical fixing. The design should avoid stress concentration at the connection point between the reinforcing rib and the nut hole, as this may lead to material fatigue or fracture. Consider nut tightening: the design of the reinforcing rib should not impede the normal tightening and loosening of the nut.

[0036] Consider the manufacturing process of the stiffeners within the nut holes to ensure they can be precisely manufactured and installed. Perform strength checks to ensure the stiffener design meets the expected load-bearing requirements. If the structure operates under cyclic loading, conduct fatigue analysis to ensure the stiffener design can withstand the expected number of cycles. Testing and Verification: Before practical application, test and verify the stiffener design to ensure it meets performance requirements. The stiffener design needs to comprehensively consider the structural stress conditions, material properties, manufacturing processes, and safety standards. In some cases, finite element analysis or other engineering calculations may be required to optimize the stiffener design.

[0037] During installation, the pipe clamp nut can be inserted into the nut hole first. Because the hole has internal reinforcing ribs and the nut hole is equilateral in shape, it can be easily pressed in and fixed. The bolt can then be screwed in using a tool. The upper and lower clamps are connected by a bolt and nut, which can be directly screwed in with a screwdriver, making it more convenient. The stepped structure also increases the thickness of the connection, making the pipe clamp less prone to breakage when tightening the bolt. Furthermore, the quick and easy installation greatly improves construction efficiency and effectively reduces installation costs.

[0038] In engineering design, the selection of pipe and pipe clamp materials should comply with relevant national design standards and specifications, while also considering factors such as the pipeline laying environment and the temperature of the transported medium. The material of PE pipe clamps is the same as that of PE pipes, mainly polyethylene (PE), which comes in several different density types, such as low-density polyethylene (LDPE), medium-density polyethylene (MDPE), and high-density polyethylene (HDPE). Polyethylene is widely used in the manufacture of pipe clamps due to its good chemical resistance, flexibility, and cost-effectiveness. The selection of pipe clamp materials also has the following requirements:

[0039] When designing PE pipe clamps, to ensure compatibility and reliable connection with PE pipes, the following key factors need to be considered: Material consistency: Ensure the pipe clamp material is the same as or compatible with the PE pipe material. Typically, the clamps should be made of the same type of polyethylene material to guarantee consistency in chemical and physical properties.

[0040] Density matching: Select pipe clamps of the appropriate density according to the density of the PE pipe (LDPE, MDPE, HDPE) to ensure compatibility between the two.

[0041] Precise dimensions: Pipe clamps must be dimensional accurately to ensure a tight fit with the pipe. This includes parameters such as inner diameter, outer diameter, and wall thickness.

[0042] Design Standards: Comply with national or international standards for the design and manufacture of PE pipes and fittings, such as GB / T13663-2000 "Polyethylene (PE) Pipes for Water Supply," etc. Pressure Resistance: Pipe clamps must be able to withstand the same working pressure as the PE pipes to prevent leaks or ruptures during system operation. Temperature Range: Consider the performance of pipe clamps at different temperatures to ensure they maintain good performance throughout the entire operating temperature range of the PE pipes.

[0043] Long-term stability: Evaluate the long-term stability of pipe clamp materials, including aging resistance and chemical corrosion resistance, to ensure reliable long-term operation. Installation ease: Design pipe clamps for easy installation and removal to facilitate on-site construction and future maintenance.

[0044] Quality Control: Strict quality control measures are implemented during the production process to ensure that each pipe clamp meets design and performance requirements. By comprehensively considering these factors, compatible and reliable PE pipe clamps can be designed to ensure the stability and safety of the entire piping system.

[0045] In this embodiment, the through hole and internal thread are not large. To achieve a stable connection, the machining accuracy is also very important. The finishing methods for the through hole mainly include the following:

[0046] Reaming: This is a commonly used hole finishing method, suitable for smaller holes. Compared to internal grinding and precision boring, reaming is an economical and practical machining method. During reaming, the allowance has a significant impact on the quality. Generally, the allowance for rough reaming is 0.35–0.15 mm, and for finish reaming, it is 0.15–0.05 mm. The dimensional accuracy of reamed holes is generally IT9–IT7, and the surface roughness Ra is generally 3.2–0.8 μm.

[0047] Boring: Boring is a machining method that enlarges a pre-drilled hole using a cutting tool. It can be performed on a boring machine or lathe. Diamond boring is a special boring method that can achieve very high machining accuracy (IT7~IT6) and surface finish (Ra 0.4~0.05μm). The machining accuracy of boring is IT9~IT7, and the surface roughness Ra can reach a certain level.

[0048] Grinding: Grinding is a high-precision machining method suitable for hardened holes or precision internal threads with strict tolerance requirements. Grinding can be performed on a special grinding machine and is suitable for machining various internal threads, grooves, bearing raceways, etc. Honing: Honing is a hole finishing method, especially suitable for holes with slightly larger diameters, which can improve the surface quality of the hole.

[0049] Grinding: Grinding is suitable for finishing both large and small holes, and is a machining method that can achieve high precision and low surface roughness. When selecting a suitable finishing method, factors such as hole diameter, hole depth, workpiece material, shape, size, weight, batch size, and specific production conditions in the workshop need to be considered.

[0050] like Figure 1 In the illustrated embodiment, the main components of the pipe clamp include an upper clamp 1, a lower clamp 2, a pipe clamp nail 6, a reinforcing rib 7, and a connector 10. During use, the pipe is placed inside the lower clamp 2, which has an arc-shaped structure to conform to the pipe. The upper clamp 1 is then inserted, and the pipe clamp nut 4 is inserted into the nut hole. Simultaneously, the pipe clamp bolt 3 is screwed in to install, forming the pipe clamp. The pipe clamp bolt 3 and pipe clamp nut 4 are used for fixed connection, ensuring stable pipe fixation during use.

[0051] like Figure 2 and Figure 3 As shown, during the installation process, the upper and lower clamps are fixed by nuts and bolts. The upper clamp 1 has a reinforcing rib 7 inside to increase the stability of the pipe clamp. The upper clamp 1 has bolt holes 8 at both ends. The bolt holes 8 are the same size as the bolts. When screwed in, they can fit perfectly and be embedded. After the pipe clamp bolt 3 is embedded, it can fit and be hidden in the stepped hole.

[0052] like Figure 4 and Figure 5 As shown, a reinforcing rib 7 is also installed inside the lower clamp 2. Nut holes 9 are designed on both sides of the lower clamp 2. The size of the nut holes 9 is the same as that of the pipe clamp nut 4. Because of the hexagonal design, it can play a positioning role when the nut is inserted, so that the pipe clamp nut 4 will not shake during the process of screwing in the pipe clamp bolt 3.

[0053] Pipe clamp 6 is provided at the bottom of the lower clamp. Pipe clamp 6 is fixed to the lower clamp by pipe clamp nut 5. During the installation process, the upper clamp 1 and the lower clamp 2 are fixed and installed first. The bolt holes 8 on both sides of the upper clamp 1 are in contact with the nut holes 9 on both sides of the lower clamp 2. After the upper and lower clamps are fixed, a cylinder is formed.

[0054] When selecting pipe clamp pin 6, several factors need to be considered to ensure the stability of the pipe clamp and the reliability of the connection. Here are some key factors:

[0055] The dimensions of the pipe clamp pin 6 should match the pipe clamp hole diameter, including the diameter, length, and head size of the pin 6; the pipe clamp pin 6 should have sufficient strength to withstand the weight of the pipe and the pipe clamp as well as any applied external force; corrosion resistance is important if the piping system is exposed to a humid or corrosive environment, and the selection of corrosion-resistant pipe clamp pin material is crucial.

[0056] This embodiment can choose from the following materials: Plastic: Plastic clips are characterized by fast installation, light weight, and ease of transportation and handling. Plastic clips are not prone to rust, will not damage pipes, and have a certain degree of toughness and hardness, allowing them to be easily inserted into the insulation layer and secure the underfloor heating pipes. The quality of plastic clips can be judged by their hardness, toughness, low-temperature resistance, and the mechanical angle of the countersprockets. PVC: PVC pipe clips are a common choice, offering good chemical corrosion resistance and cost-effectiveness. PVC clips provide stable fixing performance and are easy to recycle. Metal: Metal clips, such as steel nails, are typically used in applications requiring stronger fixing force. Metal clips have high strength and are suitable for thicker insulation layers or use in special environments.

[0057] Some processing can be done on the surface of the pipe clamp 6: the pipe clamp 6 may require specific surface treatments, such as galvanizing, chrome plating or coating, to improve corrosion resistance and aesthetics; select appropriate pipe clamps according to the static and dynamic load requirements of the piping system; ensure that the pipe clamp 6 complies with local building and safety standards; in some cases, adjustable pipe clamps 6 may be required to accommodate the thermal expansion or uneven settlement of the pipeline; consider the environmental impact of the pipe clamp 6 and select recyclable or environmentally friendly materials.

[0058] During use, place the lower clamp 2 at the location where the pipe needs to be fixed, and fix the position of the pipe clamp nail. After determining the position of the lower clamp 2, fix the lower clamp 2 and the upper clamp 1. During construction, simply tighten the bolts on the outside of the pipe clamp with a Phillips screwdriver.

[0059] Regarding the selection of pipe clamp nuts in this embodiment: This embodiment uses polygonal nuts, typically hexagonal, but other polygonal shapes are also possible. This embodiment is not limited to hexagons; the nut selection can be designed based on the shape of the nut hole. Nuts can be manufactured using different processes, such as casting, forging, or machining. The choice of process depends on the nut's size, material, and performance requirements. The material of polygonal nuts can be carbon steel, stainless steel, or other alloys. The choice of material will affect the nut's strength, corrosion resistance, and cost. The thread is an important component of the nut, and the thread type, pitch, and thread depth need to be considered. Surface treatment: The surface treatment of the nut can include zinc plating, nickel plating, or other coatings to improve corrosion resistance and aesthetics. Appropriate mechanical performance grades need to be selected based on the nut's operating environment and load requirements. When selecting nuts, relevant industrial standards, such as GB (Chinese National Standard) or other international standards, should be followed.
