一种扣压套筒连接件

Abstract

本实用新型涉及一种扣压套筒连接件，包括锥形锁具、套筒和固定圈，套筒的内部中空且两端均敞开，套筒内部为锥形结构，即套筒内壁一端的内径大，另一端的内径小；锥形锁具为中空的圆台形，用于套在两个被连接件的外部，锥形锁具外壁的锥度角等于套筒内壁的锥度角，套筒套在锥形锁具的外部，采用过盈配合的方式实现套筒与锥形锁具的连接；锥形锁具包括至少三片分片部，分片部沿着锥形锁具的周向分布，锥形锁具的内壁具有内牙纹，便于与被连接件外壁面的纹路对应卡接；固定圈为圆形，可拆卸地套在锥形锁具的外侧，且不进入套筒内部，固定圈用于约束分片部形成完整的锥形锁具。所述扣压套筒连接件结构简单，使用方便。

Claims

1. A swage sleeve connector, characterized by, The device includes a conical lock, a sleeve, and a retaining ring. The sleeve is hollow inside and open at both ends. The sleeve has a conical structure inside, meaning that the inner diameter of one end of the sleeve is larger than that of the other end. The conical lock is a hollow frustum shape used to fit over the outside of two connected parts. The taper angle of the outer wall of the conical lock is equal to the taper angle of the inner wall of the sleeve. The sleeve fits over the conical lock, and the connection between the sleeve and the conical lock is achieved by an interference fit. The conical lock includes at least three segmented parts, which are distributed along the circumference of the conical lock. The inner wall of the conical lock has internal threads to facilitate engagement with the texture of the outer wall surface of the connected parts. The retaining ring is circular and can be detachably fitted onto the outside of the conical lock without entering the inside of the sleeve. The retaining ring is used to constrain the segmented part to form a complete conical lock.

2. The swage sleeve connection of claim 1, wherein, The outer wall of the sleeve is selected from a circle or a polygon, and the taper angle of the inner wall of the sleeve is 1-5°.

3. The swage sleeve connection of claim 1, wherein, The sleeve has a layered structure with an inner cylinder and an outer cylinder arranged concentrically. Both ends of the inner cylinder and the outer cylinder are open. The outer wall of the outer cylinder is selected from a circle or a polygon, and the interior of the inner cylinder has a conical structure.

4. The swage sleeve connection of claim 3, wherein, The outer cylinder has a conical structure inside, while the inner cylinder is a frustum shape. The outer wall of the inner cylinder is in close contact with the inner wall of the outer cylinder. The smaller outer diameter of the inner cylinder corresponds to the smaller inner diameter of the outer cylinder, and the larger outer diameter of the inner cylinder corresponds to the larger inner diameter of the outer cylinder. This makes it easier for the inner cylinder to be inserted into the outer cylinder, achieving a good fit and making the wall thickness of the entire sleeve uniform.

5. The swage sleeve connection of claim 1, wherein, The conical lock includes a conical part and a supporting part. The taper angle of the outer wall of the conical part is equal to the taper angle of the inner wall of the sleeve. The conical part can be pressed into the inside of the sleeve, while the supporting part remains outside the sleeve and is used to support the conical lock and the sleeve. The support part is circular and is fixedly connected to the end of the tapered part with the larger outer diameter, while the outer diameter of the support part remains unchanged.

6. The swage sleeve connection of claim 5, wherein, A retaining groove is provided at the connection position between the tapered part and the support part. The retaining groove is recessed into the tapered lock to hold the retaining ring and prevent the retaining ring from slipping off.

7. The swage sleeve connection of claim 1, wherein, One part of the retaining ring is broken to form a notch, making the retaining ring suitable for conical locks with different outer diameters.

8. The swage sleeve connection of claim 1, wherein, The conical lock is composed of 3-5 segments, with the central angle of each segment being 90-180°.

9. The swage sleeve connection of claim 8, wherein, When the central angle of the segment is not less than 160°, a notch is set at each end of the segment. When the conical lock is not under force, the two ends of the segment do not contact the adjacent segments on both sides. Utilizing the principle of the spring bridge, the segment can lock the internal connected parts more tightly during the process of being pressed by the sleeve.
