Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a chain with U-shaped buckle structure, including chain link 10, connecting pin 20 and U-shaped buckle 30, chain link 10 one end fixed mounting has the triangle-shaped protruding position 11 with U-shaped buckle 30 complex, connecting pin 20 inserts in the hole site of chain link 10, connect through connecting pin 20 between the chain link 10, and connecting pin 20 tip offers the annular groove 21 with U-shaped buckle 30 complex, when assembling the chain, splice two chain links 10 together, then insert connecting pin 20 in the hole site of chain link 10, make the tip of connecting pin 20 extend to inside the triangle-shaped protruding position 11, then insert U-shaped buckle 30 in annular groove 21, and make the tip of U-shaped buckle 30 insert in triangle-shaped protruding position 11, make U-shaped buckle 30 joint on triangle-shaped protruding position 11, link 10 links together in proper order through connecting pin 20 and constitutes the chain.

Wherein, parallel recess 12 has been seted up to the one end that the chain link 10 kept away from article font protruding position 11, and the afterbody of connecting pin 20 is seted up with parallel recess 12 complex spacing plane, inserts connecting pin 20 back in the hole site of chain link 10, and the afterbody of connecting pin 20 stretches into in the flat recess 12, and the spacing plane of connecting pin 20 afterbody agrees with flat recess 12, prevents that connecting pin 20 from rotating.

Wherein, U-shaped buckle 30 adopts the nylon materials to make, make U-shaped buckle 30 have certain toughness and elasticity, when inserting U-shaped buckle 30 on the protruding position 11 of article font, U-shaped buckle 30 can contract inwards in arc recess 31 position, treat that the tip of U-shaped buckle 30 passes behind the protruding position 11 of article font, under the effect of elasticity, U-shaped buckle 30's both sides kick-back, make the arc recess 21 of U-shaped buckle 30 both sides and the both sides cooperation of the protruding position of article font, barb 32 joint of U-shaped buckle 30 tip forms the auto-lock on the protruding position 11 of article font, make U-shaped buckle 30 joint on the protruding position 11 of article font.

Arc-shaped grooves 31 are formed in two sides of the U-shaped buckle 30, barbs 32 are formed at end portions of two sides of the U-shaped buckle 30 through the arc-shaped grooves 31, and after the U-shaped buckle 30 is inserted into the annular groove 21, the barbs 32 at the end portions of the U-shaped buckle 30 are clamped on the triangular convex portions 11 to form self-locking under the action of elastic force, so that connection between the chain links 10 is firmer.

The working principle is as follows: when using, splice two chain links 10 together, then insert connecting pin 20 in the hole site of chain link 10, make the tip of connecting pin 20 extend to inside the protruding position 11 of article font, then insert U-shaped buckle 30 in the annular groove 21, and make the tip of U-shaped buckle 30 insert in the protruding position 11 of article font, after passing the tip of U-shaped buckle 30 the protruding position 11 of article font, under the effect of elasticity, the both sides of U-shaped buckle 30 kick-back, make the arc groove 21 of U-shaped buckle 30 both sides and the both sides cooperation of the protruding position of article font, barb 32 joint of U-shaped buckle 30 tip forms the auto-lock on the protruding position 11 of article font, make U-shaped buckle 30 joint on the protruding position 11 of article font, connect gradually chain link 10 together through connecting pin 20, it is more convenient to install, the phenomenon that pine takes off and axial displacement can not appear in long-term use, avoid causing the chain to damage.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
