A traditional pipe clamp module usually has an installation seat of an assembly screw arranged at a central position between two extension portions (openings) of a semi-ring-shaped clamp. When the pipe clamp body is installed on the wall surface through the assembly screw, the extension portions on all pipe clamp bodies are parallel to the wall surface, and the two extension portions of two adjacent pipe clamp bodies are exactly on the same straight line, which causes the following technical defects:

[0027] Embodiment 1

[0028] As mentioned in the background, in order to solve the problems in the prior art, the present application provides a PVC drain pipe clamp module installed obliquely, as shown in Figure 1 , comprising:

[0029] a plurality of pipe clamp bodies, each of which comprises:

[0030] two half-ring clamps 6 which are detachably connected and form a first space for penetrating the pipe to be clamped between them; two end portions of each of the half-ring clamps 6 extend outward in opposite directions to form an extension 5;

[0031] a first mounting seat 4 provided on the side of one of the half-ring clamps 6 away from the first space, the first mounting seat 4 being used for mounting the pipe clamp body on the wall surface 1, and the mounting axis direction of the first mounting seat 4 being at a 45-degree angle with the extension direction of the extension 5 of one side of the half-ring clamp 6;

[0032] wherein, when all the pipe clamp bodies are mounted on the wall surface 1, the extension direction of the extension 5 of each of the pipe clamp bodies is at a 45-degree angle with the wall surface 1, so that two adjacent extensions 5 of two adjacent pipe clamp bodies are staggered with each other.

[0033] Specifically, the semi-annular clamp 6 is a semi-circular structure for surrounding and fixing the pipe, made of PVC material with certain toughness and strength. The extension 5 is a flat structure extending outward from both ends of the semi-annular clamp 6, used to realize the connection and fixation of the two semi-annular clamps 6. The first space is a circular space formed after the two semi-annular clamps 6 are closed, with a diameter matching the outer diameter of the PVC drainage pipe to be clamped, ensuring that the pipe can pass through it tightly. The installation axis direction is the central axis direction when the first mounting seat 4 is connected with the wall 1, representing the force transmission direction and installation reference direction. The manufacturing of the semi-annular clamp 6: integrated by injection molding, the mold design determines the inner diameter size of the semi-annular clamp 6 according to the target pipe diameter, usually with a tolerance of 0.5-1mm to ensure tight installation. The formation of the extension 5: during the injection molding process, the mold structure at both ends of the semi-annular clamp 6 directly forms the outwardly extending flat extension 5, with an extension length of 30-50mm and a width consistent with the wall thickness of the semi-annular clamp 6. The setting of the first mounting seat 4: the first mounting seat 4 is integrally formed on the outside of one of the semi-annular clamps 6 (away from the first space side) by the injection molding process, and the center of the mounting seat and the line connecting the center of the semi-annular clamp 6 form a 45-degree angle. By setting the installation axis of the first mounting seat 4 and the extension direction of the extension 5 at a 45-degree angle, when the pipe clamp body is installed on the wall 1, the extension 5 naturally tilts at a 45-degree angle with the wall 1. The extensions 5 of adjacent pipe clamp bodies are staggered, using spatial geometric principles to reduce the horizontal space occupation while ensuring the pipe support strength.

[0034] The present embodiment can realize: space optimization: the extensions 5 of adjacent pipe clamps are staggered, reducing the horizontal width of multiple side-by-side installed pipe clamp modules by about 30%, suitable for pipe installation in narrow spaces. Installation flexibility: the 45-degree inclined design makes the pipe clamp layout on the wall more flexible and can adapt to different directions of the pipe. Structural strength: the inclined angle of the extension 5 is optimized by mechanical calculation to ensure uniform stress distribution when supporting the weight of the pipe, improving the service life of the pipe clamp.

[0035] In a preferred embodiment, the first mounting seat 4 is provided with a threaded hole, the axis of the threaded hole coincides with the installation axis, and is connected with the second mounting seat 2 embedded in the wall through the assembly screw 3.

[0036] Specifically, the threaded hole is a cylindrical hole opened inside the first mounting seat 4, and the hole wall is processed with internal threads for cooperation with the assembly screw 3 to realize connection. The second mounting seat 2 is a structural member pre-buried in the wall body, usually made of metal material, and has a connecting structure corresponding to the first mounting seat 4. The assembly screw 3 is a fastener for connecting the first mounting seat 4 and the second mounting seat 2, usually made of stainless steel material, and the threaded hole is processed: M8-M12 threaded hole is processed on the injection molded first mounting seat 4 by mechanical tapping process, with a depth of 15-25mm. The second mounting seat 2 is pre-buried: during the wall construction stage, the second mounting seat 2 (such as pre-buried steel plate or metal sleeve with external threads) made of metal material is fixed in the wall body according to the design position, ensuring that its mounting surface is flush with the wall surface 1. The assembly screw 3 is selected: according to the weight and stress condition of the pipeline, the appropriate specification of the assembly screw 3 is selected, such as M8x30 or M10x40, etc. The first mounting seat 4 and the second mounting seat 2 pre-buried in the wall body are firmly combined through threaded connection. Threaded connection has self-locking characteristics, which can effectively resist vibration and external force, ensuring the stability of the connection. The threaded hole axis coincides with the mounting axis, ensuring that the tightening force applied by the assembly screw 3 is transmitted along the mounting axis direction, so that the pipe clamp body is tightly attached to the wall surface 1.

[0037] The present embodiment can realize: reliable connection: threaded connection can provide high tensile and shear strength, ensuring that the pipe clamp will not loosen during long-term use. Convenient installation: compared with welding or other fixing methods, the use of assembly screw 3 connection is more convenient, which can greatly shorten the installation time. Maintainability: when the pipe clamp needs to be replaced or repaired, the assembly screw 3 only needs to be unscrewed to easily disassemble, reducing maintenance cost.

[0038] In a preferred embodiment, the pipe clamp body is made of PVC material, and the first mounting seat 4 and the semi-annular clamp 6 are integrally formed by injection molding process.

[0039] Specifically, PVC material is polyvinyl chloride material, which has the characteristics of corrosion resistance, light weight and low cost, with a density of about 1.3-1.4g / cm³ and a tensile strength of 40-60MPa. Injection molding process: after heating and melting PVC particles, they are injected into the mold cavity by pressure, and after cooling and solidification, the desired shape is formed. Integrally formed means that the semi-annular clamp 6 and the first mounting seat 4 are formed at the same time by one injection molding process, so that they become an integral structure.

[0040] The embodiment can realize: high structural strength: when the integrally formed pipe clamp body bears external force, the stress distribution is more uniform, and the anti-deformation capacity is improved by about 20% compared with the assembled structure. Good corrosion resistance: PVC material itself has excellent acid and alkali corrosion resistance, and is suitable for humid and highly corrosive environments, such as drainage systems in chemical plant rooms. Cost reduction: The number of parts and assembly processes is reduced, the production efficiency is improved by about 30%, and the production cost is reduced.

[0041] In a preferred embodiment, each of the second mounting seats 2 has a corresponding first mounting seat 4, and the mounting axis direction of the first mounting seat 4 is perpendicular to the wall surface 1.

[0042] Specifically, the mounting axis direction is the central axis direction when the first mounting seat 4 is connected to the wall surface 1, representing the force transmission direction and the installation reference direction. The wall surface 1 is perpendicular to the mounting axis direction, which is consistent with the normal direction of the wall surface 1, that is, the mounting axis forms a 90-degree angle with the wall surface 1. The second mounting seat 2 is positioned: during the wall construction stage, a laser level or other measuring tool is used to determine the installation position of the second mounting seat 2 to ensure that its installation surface is perpendicular to the wall surface 1. Pre-buried fixation: the second mounting seat 2 is fixed in the wall through expansion bolts or concrete pouring, and a level is used to detect its perpendicularity, with a deviation controlled within ±0.5 degrees. The first mounting seat 4 is adapted: according to the position and direction of the second mounting seat 2, the structure of the first mounting seat 4 is designed so that its mounting axis direction is perpendicular to the installation surface of the second mounting seat 2. When the mounting axis direction of the first mounting seat 4 is perpendicular to the wall surface 1, the tightening force applied by the assembly screw 3 can act vertically on the wall surface 1, generating the maximum friction force between the pipe clamp body and the wall surface 1, thereby improving the stability of the connection. Vertical installation can also evenly transmit the weight of the pipe to the wall surface 1, avoiding lateral component forces that cause the pipe clamp to loosen.

[0043] The embodiment can realize: improved connection stability: the vertical installation method increases the friction force between the pipe clamp and the wall surface 1, and the anti-slip capacity is improved by about 30% compared with the inclined installation when bearing the weight of the pipe. Uniform stress: the weight of the pipe is directly transmitted to the wall through the vertical mounting axis, reducing the bending stress of the pipe clamp body and prolonging the service life. Improved installation accuracy: vertical installation based on the wall surface 1 facilitates quick and accurate positioning for construction personnel, reducing installation difficulty and improving construction efficiency.

[0044] In a preferred embodiment, the extension 5 is provided with a first through hole 7, and a first connecting piece 8 is further provided in the two first through holes 7 on the same side of the two half-ring clamps 6.

[0045] Specifically, the two half-ring clamps 6 are firmly connected together to form a complete annular structure by opening a first through hole 7 on the extension 5 and using a first connecting piece 8 to pass through it, thereby achieving clamping and fixing of the pipeline. The pre-tightening force of the first connecting piece 8 causes the two half-ring clamps 6 to generate radial pressure on the pipeline, which resists the movement of the pipeline through friction with the surface of the pipeline, ensuring the stability of the pipeline.

[0046] In a preferred embodiment, an angle adjusting assembly is provided between the assembly screw 3 and the threaded hole, which includes a spherical washer and a conical locking sleeve, for compensating for the angular deviation of the wall mounting surface.

[0047] Specifically, the angle adjusting assembly: a device for compensating for the angular deviation of the wall mounting surface, consists of a spherical washer and a conical locking sleeve. Spherical washer: a washer with a spherical surface, the spherical radius is usually 20-50mm, which can adapt to the change of angle within a certain range. Conical locking sleeve: a conical sleeve structure, the outer surface is a conical surface, the taper is usually 1:10-1:20, used to cooperate with the spherical washer to realize angle adjustment and locking. Spherical washer manufacturing: made of metal materials (such as carbon steel or stainless steel) by forging or mechanical processing, the spherical surface is polished, the roughness Ra≤0.4μm. Conical locking sleeve manufacturing: also made of metal materials, processed into a conical structure by turning, the inner hole is processed with threads matching the assembly screw 3. Assembly of components: the spherical washer and the conical locking sleeve are successively sleeved on the assembly screw 3, and then the assembly screw 3 is screwed into the threaded hole of the first mounting seat 4. When the wall mounting surface has an angular deviation, the spherical washer can rotate at a certain angle under the pressure of the assembly screw 3, so that it is in close contact with the wall surface 1. The conical surface of the conical locking sleeve cooperates with the spherical surface of the spherical washer. When the assembly screw 3 is tightened, the conical locking sleeve generates a radial shrinkage force, tightly locking the spherical washer at the required angle position, thereby compensating for the angular deviation of the wall mounting surface.

[0048] In a preferred embodiment, the inner wall of the half-ring clamp 6 is provided with an elastic gasket, and the surface of the elastic gasket is provided with anti-slip convex patterns.

[0049] Specifically, the elastic properties of EPDM rubber can buffer the vibration and displacement of the pipeline caused by thermal expansion and contraction, water flow impact, etc., reducing the impact force on the pipe clamp body. The anti-slip convex patterns increase the friction between the elastic gasket and the pipeline surface. According to the principle of friction mechanics, the friction is proportional to the contact area and surface roughness. The anti-slip convex patterns effectively prevent the pipeline from sliding in the clamp by increasing the contact area and surface roughness.

[0050] In a preferred embodiment, the extensions 5 of two adjacent pipe clamp bodies are staggered in the inclined direction, forming a spatially complementary layout to reduce the transverse occupation area of the pipe clamp module.

[0051] Specifically, by spatial geometry, the extensions 5 of adjacent pipe clamps are arranged in the inclined direction and staggered with each other, so that they are staggered in the transverse direction, reducing the overall transverse occupation width.

[0052] In a preferred embodiment, each of the second mounting seats 2 is arranged on the wall surface 1 in the same straight line.

[0053] Specifically, when a plurality of second mounting seats 2 are arranged in the same straight line on the wall surface 1, the pipe clamp bodies mounted thereon will also be distributed along the same straight line, allowing the multiple pipes to be arranged neatly.

[0054] In a preferred embodiment, each of the second mounting seats 2 is arranged on the wall surface 1 in an alternating offset manner, and the transverse offset distance of each second mounting seat 2 relative to the previous one along the wall surface 1 is 50%-60% of the width of the pipe clamp body.

[0055] Specifically, in addition to being arranged in a straight line, they can also be arranged in an alternating offset manner, specifically, the adjacent second mounting seats 2 are arranged in a certain distance in the front and rear directions on the wall surface 1, forming a layout similar to a ladder.

[0056] Transverse offset distance: the distance between the center positions of adjacent second mounting seats 2 in the front and rear directions on the wall surface 1, which is usually 50%-60% of the width of the pipe clamp body. The specific implementation can be: reference line determination: according to the direction of the pipe and the design requirements, a reference line is determined on the wall surface 1. First group of mounting seat positioning: the position of the first second mounting seat 2 is determined on the reference line, and then the position of the next second mounting seat 2 is determined every certain distance (usually 1.5-2 times the width of the pipe clamp body) along the reference line direction. Offset amount setting: starting from the second second mounting seat 2, each mounting seat is offset from the previous mounting seat by 50%-60% of the width of the pipe clamp body in the front and rear directions on the wall surface 1, forming an alternating offset arrangement. The alternating offset arrangement not only allows the extensions 5 of adjacent pipe clamps to be staggered in the left and right directions in space, but also allows them to be staggered in the front and rear directions, which is more adaptable.

[0057] The principles and implementation manners of the present application are described by using specific examples in the present article, and the above example descriptions are only used to help understand the method of the present application and its core idea. The above descriptions are only the preferred implementation manners of the present application. It should be noted that, due to the limited nature of the language expression, there are objectively infinite specific structures, and for ordinary skilled persons in the technical field, some improvements, refinements or changes can be made without departing from the principles of the present application, or the above technical features can be combined in an appropriate manner; these improvements, refinements, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, shall be regarded as the protection scope of the present application.
