[0036] Specifically, the upper pipe clamp part 1 is the upper half of the pipe clamp, used for clamping and fixing the PVC drain pipe in cooperation with the lower pipe clamp part 2, and is provided with a first clamping part for quick connection on one side and a first mounting hole 11 on the other side.

Among them, the upper pipe clamp part 1, the lower pipe clamp part 2 and the first mounting seat 4 can be integrally formed by injection molding and injection molding with PVC material. The first mounting seat 4 is integrally formed by mold design when the upper pipe clamp part 1 is injection molded. The first clamping part, the second clamping part, the first mounting hole 11 and the second mounting hole 21 are directly formed by the mold cavity in the injection molding process.

[0037] The present embodiment divides the pipe clamp into the upper pipe clamp part 1 and the lower pipe clamp part 2, and can quickly realize the connection of one side of the pipe clamp through the snap-fit of the first clamping part and the second clamping part, facilitating installation and operation; and the other side is realized through the penetration of the first connecting piece 3 through the first mounting hole 11 and the second mounting hole 21 and being screwed, realizing stable connection and ensuring the clamping and fixing of the pipe clamp on the PVC drain pipe. The first mounting seat 4 is used for fixing the pipe clamp on the wall surface, providing a mounting basis for the pipe clamp.

[0038] In a preferred embodiment, the upper pipe clamp part 1 is a first clamping ring in a semi-ring shape, one end of the first clamping ring extends outward in a first direction to form a first extension 12, and the center of the first extension 12 is provided with the first mounting hole 11; the first direction is the direction of the center line of the semi-ring shape and the semi-ring end;

[0039] The other end of the first clamping hoop extends outward to form a second extension 51 in the same plane as the first extension 12, and the end of the second extension 51 extends in a direction perpendicular to the second extension 51 to form a third extension 52, and the second extension 51 and the third extension 52 together form the first clamping portion;

[0040] The second clamping portion includes a U-shaped clamping groove structure 54, and the first clamping portion is embedded in the U-shaped clamping groove structure 54 to achieve buckling.

[0041] In a preferred embodiment, the lower pipe clamping portion 2 is a semicircular second clamping hoop, one end of the second clamping hoop extends outward in the first direction to form a fourth extension 22, the center of the fourth extension 22 is provided with the second mounting hole 21, and the other end of the second clamping hoop extends outward to form a fifth extension 53 in the same plane as the fourth extension 22, the fifth extension 53 is connected with the U-shaped clamping groove structure 54 to form the second clamping portion together, and the groove depth direction of the U-shaped clamping groove structure 54 is the axial direction of the pipe to be clamped inside the pipe clamp.

[0042] Specifically, the fourth extension 22 of the second clamping hoop is provided with the second mounting hole 21, which cooperates with the first mounting hole 11 of the first clamping hoop, and the pipe clamp is connected away from the quick connection end 5 through the first connecting piece 3. The fifth extension 53 is connected with the U-shaped clamping groove structure 54 to form the second clamping portion (the fifth extension 53 is in the same plane as the semicircular second clamping hoop, and then the fifth extension 53 is vertically connected to one of the vertical parts of the U-shaped clamping groove structure), cooperates with the first clamping portion, and is embedded in the U-shaped clamping groove structure 54 to achieve buckling, thereby completing the connection of the quick connection end 5 of the pipe clamp. The groove depth direction of the U-shaped clamping groove structure 54 is the axial direction of the pipe to be clamped inside the pipe clamp, which makes the pipe clamp better adapt to the shape and stress direction of the pipe.

[0043] In a preferred embodiment, the second extension 51 and the third extension 52 can be embedded in the U-shaped clamping groove structure 54, and the first clamping portion and one of the vertical parts 55 of the U-shaped clamping groove structure 54 form a spatially crossed bite, so that the first clamping portion and the second clamping portion are connected in plane limiting.

[0044] Specifically, the first clamping part and the U-shaped clamping groove structure 54 are precisely controlled in shape and size by the mold when the upper pipe clamp part 1 and the lower pipe clamp part 2 are injection molded, so as to ensure that the first clamping part can be accurately embedded in the U-shaped clamping groove structure 54 and achieve spatial cross occlusion. During mold design, the shape and position of the first clamping part and the U-shaped clamping groove structure are planned in detail, and through multiple mold testing and adjustment, the occlusion effect is ensured. When the first clamping part is embedded in the U-shaped clamping groove structure 54, the first clamping part and one of the vertical parts 55 of the U-shaped clamping groove structure 54 (that is, the other vertical part 55 not connected with the fifth extension part 53, the U-shaped groove is composed of two vertical parts and a horizontal part connecting the two vertical parts) form spatial cross occlusion, which limits the relative movement of the first clamping part and the second clamping part in the plane direction (that is, the plane direction of the pipe clamp at this time), thereby achieving plane limiting connection. Even when the pipe is subjected to external force (such as water flow impact, vibration caused by radial movement of the pipe, etc.), the connection part of the pipe clamp will not easily loosen or dislocate, thereby ensuring the stable clamping of the pipe clamp on the pipe.

[0045] In a preferred embodiment, the first connecting part 3 is an assembly screw, and the inner walls of the first mounting hole 11 and the second mounting hole 21 are provided with a threaded structure matched with the assembly screw.

[0046] Specifically, the assembly screw is used as the first connecting part 3, which is used to penetrate the first mounting hole 11 and the second mounting hole 21 and is tightened to complete the standard fastener of the pipe clamp away from the quick connection end 5. The threaded structure is a helical thread formed on the inner walls of the first mounting hole 11 and the second mounting hole 21, which is matched with the assembly screw and achieves fastening connection through thread cooperation. The assembly screw can be directly purchased as a standard part from the market. When the upper pipe clamp part 1 and the lower pipe clamp part 2 are injection molded, the threaded structure matched with the assembly screw is formed on the inner walls of the first mounting hole 11 and the second mounting hole 21 by the mold. During mold design, according to the specifications of the assembly screw, the parameters such as thread type and pitch are accurately set to ensure that the threaded structure can be well matched with the assembly screw. By using the thread cooperation principle of the assembly screw and the threaded structure of the inner walls of the first mounting hole 11 and the second mounting hole 21, when the assembly screw penetrates the first mounting hole 11 and the second mounting hole 21 and is tightened, the friction and meshing action between the threads make the upper pipe clamp part 1 and the lower pipe clamp part 2 tightly connected together, thereby achieving stable connection of the pipe clamp away from the quick connection end 5.

[0047] In a preferred embodiment, the upper pipe clamp part 1 is made of PVC material, and the first mounting seat 4 and the upper pipe clamp part 1 are integrally formed by an injection molding process.

[0048] Specifically, the PVC material is polyvinyl chloride plastic, which has good chemical stability, corrosion resistance and certain mechanical strength, and is suitable for making the drain pipe clamp. The injection molding process is a processing technology that the PVC particles are heated and melted, then injected into the mold cavity through the injection molding machine, and molded after cooling and solidification. One-piece molding: in the injection molding process, the first mounting seat 4 and the upper clamp part 1 are molded as a whole, so that there is no obvious connection gap between them, forming a complete part.

[0049] In a preferred embodiment, the first mounting seat 4 is provided with a threaded hole 41, and is connected with the second mounting seat embedded in the wall through an assembly screw.

[0050] Specifically, the threaded hole 41 is a hole opened in the first mounting seat 4, and the inner wall has a threaded structure for cooperating with the assembly screw to realize the connection between the clamp and the second mounting seat embedded in the wall. The second mounting seat is a component embedded in the wall in advance, which is used to connect with the first mounting seat 4 through the assembly screw, and provides a stable mounting base for the clamp. When the first mounting seat 4 is injection molded, the threaded hole 41 is formed in the first mounting seat 4 through the mold. The second mounting seat can be made of metal or other suitable materials according to design requirements, and is embedded in the wall according to the designed position and depth during the construction of the wall. The assembly screw is a standard part matched with the threaded hole 41. By using the principle of threaded connection, the assembly screw is inserted into the second mounting seat embedded in the wall through the threaded hole 41 of the first mounting seat 4, and the clamp is firmly installed on the wall surface through the engagement and friction force between the threads. The second mounting seat is embedded in the wall in advance and can bear the weight of the clamp and the pipeline and other external forces, providing stable support for the clamp.

[0051] In a preferred embodiment, each second mounting seat has a corresponding first mounting seat 4, and the installation axis direction of the first mounting seat 4 is perpendicular to the wall surface.

[0052] In a preferred embodiment, an angle adjusting assembly is provided between the assembly screw and the threaded hole 41, and the angle adjusting assembly includes a spherical gasket and a conical locking sleeve, which is used to compensate for the angle deviation of the wall mounting surface.

[0053] Specifically, the angle adjusting assembly is composed of a spherical washer and a conical locking sleeve, which is used to be installed between the assembly screw and the threaded hole 41, to compensate for the angle deviation of the wall mounting surface, and to ensure the perpendicularity and stability of the pipe clamp installation. The spherical washer is a washer with a spherical surface, which can rotate freely within a certain range, and is used to adjust the installation angle. The conical locking sleeve is a conical sleeve structure, which is used in cooperation with the spherical washer to fix the adjusted angle through locking. When installing the pipe clamp, first place the spherical washer in the threaded hole 41 of the first mounting seat 4, then pass the assembly screw through the spherical washer, then put on the conical locking sleeve, and finally screw the assembly screw into the second mounting seat embedded in the wall. During the process of tightening the assembly screw, the angle deviation of the wall mounting surface is compensated by adjusting the angle of the spherical washer, and finally the conical locking sleeve is tightened to fix the angle. When there is an angle deviation in the wall mounting surface, the spherical washer can rotate freely in the threaded hole 41, and by adjusting its angle, the assembly screw can be installed perpendicular to the pipe axis. After adjusting the angle, the conical locking sleeve is tightened to tightly cooperate with the spherical washer, fixing the adjusted angle, preventing the angle from changing again due to external forces during use, and thus ensuring the perpendicularity and stability of the pipe clamp installation.

[0054] In a preferred embodiment, the inner walls of the upper pipe clamp part 1 and the lower pipe clamp part 2 are each provided with an elastic gasket, the material of the elastic gasket is EPDM rubber, and the surface is provided with anti-slip ridges.

[0055] Specifically, the elastic gasket is a gasket with elasticity provided on the inner walls of the upper pipe clamp part 1 and the lower pipe clamp part 2, which is used to enhance the friction between the pipe clamp and the pipe, prevent the pipe from sliding, and also serve as a shock absorber. EPDM rubber is a ternary ethylene propylene rubber, which has good aging resistance, corrosion resistance, elasticity and impact resistance.

[0056] The principles and implementation modes of the present application are described herein by applying specific examples, and the above examples are only used to help understand the method and its core idea. The above description is only the preferred embodiment of the present application. It should be noted that due to the limitation of language expression, there are 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.
