Described fixed block can be the fixed cover that an integrated type can not break, and its intensity is greater than connecting tube intensity, and fixed block is locked on the outer surface of connecting tube, and connecting tube and link are closely fixed.
Described fixed block also can form removable fixed cover by least two accessories, its bulk strength is greater than connecting tube intensity, the pawl being provided with at least one locking between the connection part of each accessory and opening, fixed block is locked on the outer surface of connecting tube, and connecting tube and link are closely fixed.
As scheme more specifically, one end of described fixed block is arranged to horn-like, so that connecting tube passes rapidly through.
Described connecting tube is hose body; Namely, time connecting tube and link are fixed, connecting tube can open, and is extruded distortion, it is stuck in below the protruding structure of link under the effect of fixed block after being out of shape, form the structure of similar barb, make connecting tube be not easy to be drawn out, its soundness connected is better.
As further improving, the total length of described fixed block is less than the total length of the plug projection structure of link.
The beneficial effects of the utility model are as follows:
(1) this kind of is connected and fixed structure, utilize the quick grafting between link with connecting tube and coordinate protruding close contact between the two, be locked at the outer surface of connecting tube fast by fixed block again, closely fixed to make connecting tube and link, its whole operation is quick, simple and easy, protruding close contact between link and connecting tube, it is connected firmly, reliably, the impact of larger pulling force and hydraulic pressure can be born in joint; And, simple and reasonable for structure.
(2) further, the protruding structure on link plug is annular inverted triangle protuberance, be conducive to along its circumferencial direction between link and connecting tube, its close contact dynamics evenly; And, connecting tube is hose body, namely time connecting tube and link are fixed, connecting tube can open, and being extruded distortion, it is stuck in after being out of shape below the protruding structure of link under the effect of fixed block, forms the structure of similar barb, make connecting tube be not easy to be drawn out, its soundness connected is better.
(3) more have plenty of, one end of fixed block is arranged to horn-like, facilitates connecting tube to pass rapidly through, and is conducive to improving its simplification being connected and fixed operation and rapidity.
