Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a quick-insert joint type pier ring joint suitable for a smaller installation space. Background Art

[0002] The conventional methods in the existing joint market are mainly: 1. Machining the ring and then bending it separately into an elbow joint; 2. Using small-tonnage extrusion piers and rings without machining, but there are large gaps between the piers and rings, which cannot meet the customer's standard joint size requirements; 3. The joint is pre-positioned by tooling and then manually spot welded in place, which results in unstable welding quality and is time-consuming and labor-intensive.

[0003] When customers need to match standard joints, space is limited and the inner and outer diameters of the round tube cannot be adjusted. However, because conventional processing methods cannot meet the size or the processing cost is high, a better structure and process are needed to meet customer needs at a lower cost. Utility Model Content

[0004] The purpose of the present utility model is to provide a quick-connect pier ring joint suitable for a smaller installation space, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The utility model provides a quick-connect pier ring joint suitable for smaller installation space, which includes a bend pipe, a pier ring and a joint. The pier ring, the bend pipe and the joint are all integrally formed structures, and the inner wall of the pier ring and the bend pipe and the joint form an arc transition.

[0007] Furthermore, the wall thickness of the end face of the pier ring is 1.5 to 2 times the wall thickness of the elbow.

[0008] Furthermore, the cross section of the pier ring is a seamless structure.

[0009] Furthermore, the outer contour of the pier ring is waist-shaped, and the outer contour width of the pier ring is ≤ the diameter of the pipe opening of the elbow.

[0010] Furthermore, the wall thickness of the joint is 1 mm.

[0011] Furthermore, the diameter of the joint is consistent with the diameter of the pipe opening of the elbow.

[0012] Beneficial effects: A quick-insert pier ring joint suitable for smaller installation spaces utilizes a tight and seamless pier ring structure to replace the original circular tube wall structure formed by extrusion of the upper and lower layers, thereby achieving process-based wall thickness thinning and matching the common quick-insert pipe joints on the market. By changing the original circular hole structure to a waist-shaped hole structure, the required accuracy of the welding surface is reduced, thereby improving the production yield. The wall thickness of the joint is milled thin, which is more convenient for riveting positioning and makes the riveting quality more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] Example

[0019] like Figure 1-2 As shown, a quick-connect pier ring joint suitable for smaller installation space includes an elbow 1, a pier ring 2 and a joint 3. The pier ring 2, the elbow 1 and the joint 3 are all integrally formed structures, and the inner wall of the pier ring 2 and the elbow 1 and the joint 3 are in an arc transition.

[0020] The wall thickness of the end face of the pier ring 2 is 1.5 to 2 times the wall thickness of the elbow 1, and the wall thickness of the end face of the pier ring 2 is less than 2 times the wall thickness of the elbow 1. The cross-section of the pier ring 2 is a seamless structure. The seamless structure is tighter, which improves the structural strength and reduces the overall wall thickness, so that it can match the common quick-insert pipe joints with long usage time. The outer contour of the pier ring 2 is waist-shaped, and the outer contour width of the pier ring 2 is ≤ the diameter of the pipe mouth of the elbow 1. The pier ring 2 adopts a structure that changes the joint positioning circular hole into a waist-shaped hole, which reduces the requirements for the welding surface and improves the wall thickness of the welding area to improve the production yield.

[0021] The wall thickness of the joint 3 is 1 mm, and the diameter of the joint 3 is consistent with the diameter of the pipe mouth of the elbow 2. The wall thickness of the joint 3 is milled thin, which makes it easier to rivet positioning and makes the riveting quality more stable.

[0022] In the utility model, a tight and seamless pier ring structure is used to replace the original circular tube wall structure formed by extrusion of the upper and lower layers, so as to achieve process-oriented wall thickness thinning and match the common quick-insert pipe joints on the market. By changing the original circular hole structure to a waist-shaped hole structure, the required accuracy of the welding surface is reduced, thereby improving the production yield. The wall thickness of the joint is milled thin, which is more convenient for riveting positioning and makes the riveting quality more stable.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
