Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to an air blocker. Background Technology

[0002] An air blocker is a device whose drain pipe is not directly connected to the receiver, but drains water below the overflow edge of the receiver and above the U-shaped bend liquid seal. It is used to indirectly connect one drain pipe to another and has functions such as unblocking, cleaning, and water sealing. However, existing air blockers often use clamps for structural connection. During assembly, it is easy for the connection body and the clamp installation range to be inconsistent, resulting in the safety hazard of the clamp falling off, as well as problems such as difficulty in position calibration and reduced installation efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an air blocker that positions the clamps, improving the efficiency of clamp installation and achieving rapid installation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a main body and a sealing cover. An air inlet pipe and an air outlet pipe are fixedly connected to the main body. A baffle is provided inside the main body. An elbow and an adjusting pipe are provided on the sealing cover. A clamp for locking the elbow and the adjusting pipe is provided at one end of the adjusting pipe. A rivet is provided on the clamp near the sealing cover. A positioning component that engages with the rivet is provided on the elbow. The positioning component includes an integrally formed locking ring, a connecting part, an extension leg, and a locking part. The locking ring is locked onto the outer circumferential surface of the elbow. One end of the connecting part is connected to the locking ring, and the other end is bent and extends to the rivet side. One end of the extension leg is connected to the connecting part, and the other end passes through the rivet side. One end of the locking part is connected to the extension leg, and the other end is locked to the rivet side.

[0005] By adopting the above technical solution, the snap-fit ​​ring is clamped onto the outer circumference of the elbow to form an axial positioning of the positioning component. At the same time, the connecting part connects to the snap-fit ​​ring and passes through one side of the rivet to achieve the installation and positioning of the clamp. The extension leg passing through the rivet can play a stable support role for the clamp. When the extension leg is inserted into the rivet, the snap-fit ​​part can press and set on the rivet, realizing the bidirectional limiting of the rivet and achieving the positioning function of the clamp, improving the efficiency of clamp installation and achieving the effect of rapid installation.

[0006] The present invention is further configured such that an installation platform is provided on one end of the elbow near the clamp, and a snap-fit ​​opening is provided on the snap-fit ​​ring, and the snap-fit ​​ring is snapped onto the installation platform through the snap-fit ​​opening.

[0007] By adopting the above technical solutions, the installation platform can improve the tight snapping effect of the snap ring on the elbow, enhance the stability of the structure, and the snap opening can provide deformation space to prevent structural breakage.

[0008] The present invention is further configured such that the snap ring has a plurality of protruding ribs arranged in a ring array facing the mounting platform side, and a gap is provided between adjacent protruding ribs.

[0009] Through the above technical solution, the protruding rib can increase the friction of the snap ring on the installation platform and prevent the snap ring from slipping.

[0010] The present invention is further configured such that the connecting part is specifically arranged in an L-shaped orthogonal state, one end of the connecting part is connected to the snap ring, and the other end is bent and extended towards the rivet side and connected to the extension support leg. A reinforcing rib is connected to the connecting part, and the angle of the reinforcing rib is specifically 0°-45°.

[0011] Through the above technical solution, the connecting part can connect the snap ring and the extension leg, so as to realize the positioning and support function of the snap ring on the clamp. The reinforcing rib can increase the strength and rigidity of the connecting part and avoid the phenomenon of uneven stress.

[0012] The present invention is further configured such that an installation groove for mounting an extension leg is provided through the rivet, the extension leg is inserted into the installation groove, the snap-fit ​​part is connected to the extension leg, and the snap-fit ​​part passes through the installation groove and is snapped onto the rivet.

[0013] By adopting the above technical solution, the extension leg can be inserted into the mounting groove with the connecting part. When the clamp is installed, when the extension leg is inserted into the mounting groove, the locking part can be locked onto the rivet with the extension leg to achieve the positioning effect of the rivet, thereby achieving the supporting function of the clamp.

[0014] The present invention is further provided that a clearance opening is provided between the adjacent extended legs.

[0015] The above solution allows for the avoidance of structural interference when extending the support legs for insertion.

[0016] The present invention is further provided that the snap-fit ​​portion has a first rounded surface at the end away from the mounting groove.

[0017] By adopting the above technical solution, the first rounded surface can improve the smoothness of the insertion of the snap-fit ​​part into the mounting slot.

[0018] The present invention is further configured such that a second rounded surface is connected between the snap-fit ​​portion and the extension leg.

[0019] Through the above technical solution, the second rounded surface can avoid scratches to workers during processing and improve the aesthetics and neatness of the extended legs. Attached Figure Description
