It is used for water circulation in the swimming pool filtration system and pumping clean water or light sewage with suspended particles. The clamp ring of the existing swimming pool pump straight pipe is an integrally cast structure. The integrally cast clamp ring meets the strength and installation requirements, but it cannot be disassembled from the pipeline. If the matching parts are damaged, the pipeline must be cut off and reinstalled and connected, which is not only time-consuming and labor-intensive, but also costly. Summary of the invention

[0013] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0014] Please refer to Figure 1 to Figure 2 , a straight pipe clamp ring matching structure for a swimming pool pump, comprising a pipe body and a clamp ring body;

[0015] The pipe body is cylindrical, the interior of the pipe body is hollow and a through hole is opened in the axial direction, and an annular groove is provided on the outer wall of the pipe body near the opening end, and the cross-sectional shape of the annular groove is a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid is located on the side of the annular groove near the opening end;

[0016] The clamping ring body is an annular structure, and is provided with a fracture. The inner wall of the clamping ring body is provided with an annular boss whose shape is matched with the annular groove.

[0017] From the above description, it can be seen that the beneficial effects of the present invention are: providing a straight pipe clamp matching structure for a swimming pool pump, including a pipe body and a clamp body, an annular groove with a right-angled trapezoidal cross-section is provided on the outer wall of the pipe body, and an annular boss adapted to the annular groove is designed on the inner wall of the clamp body. Through the matching structure with a special cross-section design, the circumferential surface strength of the pipe is enhanced, and a detachable structure between the clamp body and the pipe body is realized, while also ensuring the firmness of the matching structure between the clamp body and the pipe body and the matching installation of the pipe.

[0018] Furthermore, the clamping ring body is provided with a fixing boss on the end surface facing the opening end, and the fixing bosses are arranged at intervals along the circumferential direction of the clamping ring body.

[0019] It can be seen from the above description that the fixed boss abuts against the outer wall of the pipe, which increases the matching area between the clamping ring and the pipe, improves the stability of the matching structure, and has a certain supporting and protecting effect.

[0020] Furthermore, the number of the fixing bosses is three, and the central angle of the circumference of the circle where two adjacent fixing bosses correspond to the clamping ring body is 45°.

[0021] From the above description, it can be seen that after many derivations, designs and experiments, the relative positions of the two adjacent fixed bosses are limited as above, which can ensure that the mechanical properties of the matching structure of the straight pipe and the clamping ring in the circumferential direction are optimal, and the strength of the straight pipe is enhanced to the greatest extent.

[0022] Furthermore, a rubber layer is provided on the inner wall of the fixing boss facing the axis of the clamping ring body.

[0023] From the above description, it can be seen that the rubber layer plays the role of increasing the friction coefficient and protecting.

[0024] Furthermore, the projection width of the clamping ring body in the radial direction of the pipe body is equal to the wall thickness of the pipe body.

[0025] Furthermore, the groove depth of the annular groove is half of the wall thickness of the pipeline body.

[0026] From the above description, it can be seen that the wall thickness of the clamp body and the pipe body are designed to be the same, and the depth of the annular groove accounts for 1 / 2 of the wall thickness of the pipe body, which not only improves the mechanical properties of the matching structure of the two, but also reduces the mold production and processing costs.

[0027] Furthermore, a sealing ring is provided between the annular groove and the annular boss.

[0028] From the above description, it can be seen that the sealing ring plays a role of sealing and shock absorption, thereby extending the service life of the component.

[0029] Furthermore, the included angle between the hypotenuse and the base of the right-angled trapezoid is 45°.

[0030] It can be seen from the above description that the fixing ability of the clamping ring is enhanced and the stability of the matching structure is ensured through the matching structure with special cross-section design.

[0031] Furthermore, locking clamps are provided on both sides of the fracture of the clamp body towards the side where the opening end is located.

[0032] It can be seen from the above description that the locking clamp plays a role in facilitating the disassembly, assembly and fixation of the clamping ring.

[0033] Furthermore, an axial positioning hole is provided on the end surface of the clamp body facing the open end and located on one side of the locking clamp.

[0034] It can be seen from the above description that the positioning holes play the role of positioning and installation.
