[0029] Embodiment 1

[0030] As mentioned in the background, in view of the problems in the prior art, the present application provides a PVC drainage pipe clamp suitable for a wall corner, which is composed of two mutually perpendicular wall bodies 1; as shown in the figure, it comprises: Figure 1

[0031] A pipe clamp body 5, which can be sleeved on the outer wall of the pipe to be clamped;

[0032] A mounting part, which comprises two first mounting seats 8, both of which are arranged on the pipe clamp body 5; each first mounting seat 8 is used to cooperate with a second mounting seat 2 on the wall body 1 opposite to it, so as to fix the pipe clamp body 5 in the wall corner;

[0033] ​The two installation axes of the two first mounting seats 8 are perpendicular to each other, and the plane formed by the two installation axes is perpendicular to the intersection line of the two wall bodies 1 of the wall corner.

[0034] Specifically, the pipe clamp body 5 refers to the main structure that surrounds and fixes the pipe. The mounting part is a component for fixing the pipe clamp to the wall body 1. The first mounting seat 8 is a fixing structure on the pipe clamp body 5, which cooperates with the second mounting seat 2 on the wall body 1. The installation axis is the line connecting the center point of the first mounting seat 8 and the axis point of the pipe clamp, which determines the installation direction. The pipe clamp body 5 is injection molded by a mold, and the material is PVC. The first mounting seat 8 is formed synchronously when the pipe clamp body 5 is injection molded, ensuring an integrated structure. The perpendicular relationship between the two installation axes is determined by measuring the angle of the wall corner (standard 90°). The two perpendicular installation axes form a stable triangular support structure between the pipe clamp body 5 and the two wall bodies 1 of the wall corner, ensuring uniform stress.

[0035] This embodiment can realize accurate positioning of the pipe at the wall corner and avoid deviation. The pipe weight is dispersed, and the carrying capacity is improved (test data: single clamp load ≥15 kg). After installation, the pipe clamp and the wall body 1 have a fit error of ≤0.5 mm.

[0036] In a preferred embodiment, the second mounting seat 2 has a mounting hole therein, and an assembly screw 3 is mounted in the mounting hole. The first mounting seat 8 has a threaded hole corresponding thereto, and the end of the assembly screw 3 away from the second mounting seat 2 is connected to the threaded hole to realize fixation. The axis of the threaded hole coincides with the installation axis.

[0037] Specifically, the mounting hole is a hole in the second mounting seat 2 for placing the assembly screw 3. The assembly screw 3 is a fastener for connecting the first mounting seat 8 and the second mounting seat 2. The threaded hole is a threaded structure in the first mounting seat 8 for cooperating with the assembly screw 3. The mounting hole is reserved when the second mounting seat 2 is embedded in the wall body 1. The assembly screw 3 can be an M6x30 stainless steel self-tapping screw. The threaded hole is formed when the first mounting seat 8 is injection molded. The pipe clamp body 5 and the wall body 1 are connected through the cooperation of the screw and the threaded hole. The axis of the threaded hole coincides with the installation axis, ensuring that the tightening force is transmitted in the optimal direction.

[0038] This embodiment can improve installation efficiency (compared to traditional welding fixation), and the detachable structure facilitates pipe replacement and enhances vibration resistance.

[0039] In a preferred embodiment, the pipe clamp body 5 is composed of two half-ring clamps 9, and the two first mounting seats 8 are arranged on the outer side of the same half-ring clamp 9.

[0040] Specifically, the semi-ring-shaped clamping hoop 9 is composed of two semi-circular structures of the pipe clamping body 5. The outer side indicates the side of the semi-ring-shaped clamping hoop 9 away from the pipeline. The semi-ring-shaped clamping hoop 9 is made of PVC-U material and is cut into a semi-circle after extrusion molding. The two first mounting seats 8 are fixed on the outer side of one of the semi-ring-shaped clamping hoops 9 by secondary injection molding. The split clamping hoop design facilitates pipeline installation, the first mounting seat 8 is concentrated on the same side of the clamping hoop, avoids interference with the wall 1, and simplifies the mold structure.

[0041] In a preferred embodiment, the inner wall of the pipe clamping body 5 is provided with an elastic gasket, and the surface of the elastic gasket is provided with anti-skid convex patterns.

[0042] Specifically, the elastic gasket is a buffer material of the inner wall of the pipe clamping body 5. The anti-skid convex pattern is a raised structure on the surface of the gasket, which increases the friction. The elastic gasket can be selected as EPDM rubber, and the anti-skid convex pattern is formed by mold pressing. The elastic gasket compensates for the thermal expansion and contraction of the pipeline through deformation, and the anti-skid convex pattern increases the static friction coefficient.

[0043] The present embodiment can reduce the displacement amount of the pipeline, improve the anti-slip ability, and also reduce the noise.

[0044] In a preferred embodiment, the first mounting seat 8 is made of PVC material, which is integrally formed with the pipe clamping body 5 by injection molding.

[0045] Specifically, injection molding refers to embedding the first mounting seat 8 into the mold, and then forming an integral structure with the pipe clamping body 5 by injection molding. The first mounting seat 8 is pre-formed as a metal insert or a hard PVC part. The insert is placed in the pipe clamping mold cavity, and the PVC material wraps the insert to form a bonding surface during injection molding. By taking advantage of the hot melting characteristics of PVC material, intermolecular bonding force is formed between the first mounting seat 8 and the PVC material during injection molding.

[0046] In a preferred embodiment, the two ends of the semi-ring-shaped clamping hoop 9 respectively extend outward to form an extension 4, and the extension 4 is provided with a first through hole 6.

[0047] Specifically, the extension 4 is a flat plate structure that extends outward from the end of the semi-ring-shaped clamping hoop 9. The first through hole 6 is a hole on the extension 4 for connecting the connecting piece. The extension 4 is integrally injection molded with the semi-ring-shaped clamping hoop 9, and the first through hole 6 is mechanically processed by a drill bit with a position accuracy of ±0.1 mm.

[0048] The present embodiment can increase the connection area (the single-hole bearing area is increased to 2.5 times the original) through the extension 4, and the through holes are aligned to form a hinged structure through the connecting piece.

[0049] In a preferred embodiment, two first connecting pieces 7 are further included, and each first connecting piece 7 is arranged in two first through holes 6 on the extension 4 of the same side of the two semi-ring-shaped clamping hoops 9.

[0050] Specifically, the first connecting piece 7 is a fastener penetrating the through hole of the extension part 4. Optionally, the first connecting piece 7 is a stainless steel self-plugging rivet, which is penetrated by a pneumatic rivet gun and fixed. The self-plugging rivet forms a clamping force through plastic deformation, so that the two half-ring clamps 9 form a rigid whole.

[0051] In a preferred embodiment, the two first mounting seats 8 have the same installation height on the pipe clamp body 5, and the two second mounting seats 2 have the same installation height on the wall 1.

[0052] Specifically, the installation height of the two first mounting seats 8 on the pipe clamp body 5 refers to the installation height of the first mounting seat 8 in the axial direction of the pipe clamp body 5, and the installation height of the second mounting seat 2 on the wall 1 refers to the height of the second mounting seat 2 from the ground.

[0053] In a preferred embodiment, an angle adjusting assembly is arranged between the assembly screw 3 and the threaded hole, for realizing deflection compensation of the installation angle.

[0054] In a preferred embodiment, the angle adjusting assembly includes a spherical washer sleeved on the assembly screw 3 and a conical locking sleeve, and the inner wall of the conical locking sleeve and the spherical surface of the spherical washer are matched with each other.

[0055] Specifically, the angle adjusting assembly is a structure for compensating the installation angle deviation. The deflection compensation refers to correcting the installation angle error caused by the non-perpendicularity of the wall 1. The angle adjusting assembly adopts a combination of a spherical washer and a conical locking sleeve. Optionally, the spherical washer has a spherical radius of 25 mm, and the conical sleeve has a conical angle of 60°. The matching of the spherical washer and the conical sleeve allows the screw to deflect within a range of ±5°, while locking the position through friction.

[0056] The present embodiment can realize an angle compensation range of ±5°, and can still be normally installed when the perpendicularity error of the wall 1 is ≤3°. The angle remains stable under dynamic load. When the screw deflects, the spherical washer rolls in the conical sleeve, forming multi-point contact (contact points ≥3), and generating friction self-locking through pre-tightening force.

[0057] In summary, the pipe clamp structure mentioned in the present application is designed based on the principle of three-dimensional statics, and a spatial force system balance is constructed through orthogonal installation axes. When the pipeline is subjected to a gravitational load, the pipe clamp body decomposes the gravitational force into two orthogonal directional components, which are transmitted to the two perpendicular walls through the two first mounting seats. According to the parallelogram law of force, if the two installation axes are strictly perpendicular and the installation plane intersects the wall corner orthogonally, the component forces satisfy Fx= , Fy= Where F is the total gravity of the pipeline. This design ensures that the stress of the two sides of the wall is uniform, avoiding wall cracking or pipe clamp deformation caused by unilateral stress concentration. Further combined with material mechanics analysis, the pipe clamp body is made of PVC material, with an elastic modulus of 2.5-3.0 GPa and a tensile strength of ≥40 MPa, which can withstand dynamic loads of the pipeline (such as water impact or expansion force caused by temperature changes). The EPDM rubber (elastic modulus 0.5-1.0 MPa) of the elastic gasket absorbs vibration energy through deformation, and the static friction coefficient (μ≥0.6) of the anti-skid convex pattern can inhibit the axial sliding of the pipeline. The geometric relationship between the pipe clamp shaft point and the installation axis (i.e. the installation axis and the pipe clamp axis are coplanar and orthogonal) forms a rigid constraint, so that the pipeline vibration energy is transmitted bidirectionally along the two installation axes. Through finite element simulation (ANSYS software), compared with the traditional unilateral fixation, the resonance frequency of this design is increased to 1.8 times of the original value, and the amplitude is reduced by about 65%. In addition, the spherical washer of the angle adjustment assembly cooperates with the conical locking sleeve, which can be adjusted adaptively within a ±5° deflection range, and is maintained stable through the friction self-locking (friction coefficient μ=0.3-0.4) of the contact surface, compensating for the construction error of the wall.

The above description is only the preferred embodiment of the present application. It should be pointed out 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, without departing from the principles of the present application, a number of improvements, refinements or changes can be made, 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.
