Description of reference numerals: the anti-falling clamp comprises a connecting sleeve 1, a connecting shaft 2, a connecting block 21, an anti-falling clamp sleeve 3, a limiting block 31, a spring 4 and a connecting piece 5.
Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: the quick-change connecting mechanism comprises a connecting sleeve 1 and a connecting shaft assembly, wherein a connecting cavity with an open end is formed in the connecting sleeve 1, and the connecting shaft assembly comprises a connecting shaft 2, an anti-falling clamping sleeve 3, a spring 4 and a connecting piece 5. The head of connecting axle 2 is equipped with relative arc connecting block 21, connects the chamber and includes inner chamber and exocoel, the diameter of inner chamber is not less than the external diameter of connecting block 21, and the diameter of exocoel is unanimous with the head diameter of connecting axle 2, corresponds connecting block 21 on the lateral wall of exocoel and is equipped with the spread groove, and the head of connecting axle 2 can insert and utilize connecting block 21 card in connecting the intracavity, and the afterbody of connecting axle 2 is equipped with connecting piece 5. The anti-disengaging cutting ferrule 3 is sleeved in the middle of the connecting shaft 2 and can move back and forth along the connecting shaft 2, in one embodiment, the anti-disengaging cutting ferrule 3 is matched with the connecting shaft 2 through a sliding chute and a sliding block, so that relative rotation is avoided, the spring 4 is arranged between the anti-disengaging cutting ferrule 3 and the connecting piece 5, and when the connecting shaft 2 is inserted into a connecting cavity of the connecting sleeve 1, the anti-disengaging cutting ferrule 3 supports against the connecting sleeve 1 under the action of the spring 4.
Specifically, the head of the anti-falling clamping sleeve 3 is provided with a limiting block 31 capable of being inserted into the connecting groove, so that the connecting shaft assembly is further clamped when the connecting shaft assembly is connected with the connecting sleeve, and the reliability of connection is guaranteed. The anti-disengaging cutting ferrule 3 is provided with an installation cavity facing the connecting piece 5, the spring 4 is arranged in the installation cavity, the tail part of the anti-disengaging cutting ferrule 3 is sleeved outside the head part of the connecting piece 5, the structure is simple, and the stability is high. The diameter of the connecting piece 5 is gradually increased from the head part to the middle part and is used for limiting the anti-falling ferrule 3.
The working principle is as follows: the connecting shaft assembly is connected with the connecting sleeve: the head of the connecting shaft 2 is inserted into the connecting cavity of the connecting sleeve 1, the anti-falling clamping sleeve 3 retreats under the action of overcoming the elastic force of the spring 4, the connecting shaft assembly and the connecting sleeve 1 rotate 90 degrees relatively after the connecting block 21 on the connecting shaft 2 is inserted into the inner cavity of the connecting cavity, the connecting block 21 is clamped in the inner cavity, under the action of the elastic force of the spring 4, the limiting block 31 of the anti-falling clamping sleeve 3 is aligned with the connecting groove of the connecting sleeve to be inserted and clamped and locked, and the connecting action is finished;
the connecting shaft assembly is loosened from the connecting sleeve 1: the elasticity effect of spring 4 is overcome manually, retreats and extracts anti-disengaging cutting ferrule 3 simultaneously connecting axle subassembly and adapter sleeve 1 relative rotation 90, extracts the head of connecting axle 2 from the connecting cavity of adapter sleeve 1, and the action is accomplished with adapter sleeve 1 unclamping simultaneously connecting axle subassembly, resets under the effect of anti-disengaging cutting ferrule 3 spring 4. Simple operation and high efficiency.
