The technical field is as follows:

the utility model relates to a hasp field, concretely relates to promote hasp and use self-lubricating structure of durability.

Background art:

the hook hardware products for the handbag in the existing market are various, but the hook hardware products generally have no long-term service life, and often have the problems of poor durability, abrasion, falling of a coating film, blocked hand feeling, even abnormal operation sound and the like of parts. The spring-back capability and the use hand feeling of the pressing rod are endowed by the ejection pin matched with the spring, the axial reciprocating capability is endowed through the spring, and the service life is directly reduced due to the self-rotating force of the spring and the large-area friction of the ejection pin on the hook body in the common hook design. By combining the problems, from the viewpoint of brand value and environmental protection, the low durability will damage the trust level and the reputation; it is also a waste of resources.

The utility model has the following contents:

the utility model aims to solve the technical problem that a promote hook and detain self-lubricating structure who uses durability is provided.

The utility model discloses the technical problem that will solve adopts following technical scheme to realize: the utility model provides a promote hook-and-loop and use moist structure certainly of durability, includes and presses stick, spring, ejecting round pin, main part, press the stick to articulate in the main part top side, flexible chamber has been seted up to the downside inner wall of main part, and flexible intracavity portion swing joint has ejecting round pin, ejecting round pin is including ejecting head and joint post, the outside winding of joint post has the spring, the spring is located between ejecting head and the flexible chamber bottom.

Preferably, the top of the ejector head is rounded.

Preferably, a plurality of concave holes are densely formed in the side wall of the ejection pin.

Preferably, the concave hole is filled with lubricating oil.

The utility model has the advantages that: the utility model discloses simple structure, convenient and practical has prolonged life, and the lubricating oil of infiltration can reduce the self-rotation power of spring itself and the frictional resistance of ejecting round pin large tracts of land friction hook buckle main part in the ejecting round pin, improves the incorruptibility, easily popularizes and applies.

Example (b): as shown in fig. 1-2, a promote self-lubricating structure of knocker use durability, includes and presses excellent 1, spring 2, ejector pin 3, main part 4, press excellent 1 to articulate in main part 1 top side, flexible chamber has been seted up to the downside inner wall of main part 4, flexible intracavity swing joint has ejector pin 3, ejector pin 3 is including ejecting head 301 and joint post 302, the outside winding of joint post 302 has spring 2, spring 2 is located between ejecting head 301 and the flexible chamber bottom.

Preferably, the top of the ejector head 301 is rounded, and can be used with a press rod.

Preferably, a plurality of concave holes 303 are densely arranged on the side wall of the ejector pin 3.

Preferably, the concave hole 303 is filled with lubricating oil 304.

The raw material used in the present invention is 316L feedstock for metal injection molding

The median size of the metal powder in the feedstock should be between 5 and 15 microns.

The theoretical density of the feed after injection molding, degreasing and sintering is 75-85%

The mold cavity is filled with the feed material through an injection molding machine.

And (4) demolding, cutting off a pouring gate, arranging the disc, degreasing and sintering.

And soaking the sintered blank in lubricating oil, and placing the sintered blank in a vacuum furnace for vacuumizing to enable the lubricating oil to permeate into the sintered blank.

The oil content of the product of the present invention should be between 15% and 25%.
