Elastic hook pin device

Abstract

The invention belongs to the field of machinery, and particularly relates to an elastic hook pin device which comprises an elastic pull buckle pin, the elastic pull buckle pin comprises an elastic hook pin or an elastic buckle rivet or a non-return elastic hook pin, the elastic hook pin comprises a pin shaft blocking table, a pin penetrating shaft and a pin shaft retaining table, and the elastic buckle rivet comprises a rivet outer retaining barrel and an elastic hook pin. The rivet outer retaining barrel comprises a rivet penetrating outer barrel and a rivet outer barrel retaining table, the elastic hook pin comprises an elastic blind rivet retaining table, an elastic blind rivet barrel and an elastic buckle outer barrel retaining table, and the rebounding hook pin comprises a winding drum inner hole and a winding drum inner rebounding piece; the elastic pull buckle pin does not retreat or fall off, is fast to install, durable, few in parts, low in manufacturing cost, long in service life and high in use safety performance, saves a large amount of manpower and material resources, and improves the comprehensive safety performance and the use efficiency of equipment.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to an elastic hook pin device. Background technique [0002] At present, rivets are commonly used parts for connecting two objects. The commonly used rivets are composed of rivet barrels. Because the rivet barrels do not have the function of retracting and rebounding, in riveting, the rivets use their own deformation or interference to connect the riveted parts, so only The rivet cylinder can be made thinner, so that the strength of the rivet is poor, so that the end of the rivet cylinder can be made into hook teeth that can hook the article by external force after the end of the rivet cylinder passes through the riveted article. It is formed by bending, so the hook teeth are easy to break at the bend. In order to avoid the cracking of the riveted articles due to the breakage of the hook teeth of the riveting cylinder, the high-strength connection is basically bolted, but the bolt connectio...

Problems solved by technology

[0002] At present, rivets are common parts used to connect two objects. Commonly used rivets are composed of a rivet barrel. Because the rivet barrel has no function of retraction and springback, in riveting, the rivet uses its own deformation or interference to connect the riveted parts, so only The rivet barrel can be made relatively thin, so that the strength of the rivet is poor, so that after the end of the rivet barrel passes through the riveted object, the end of the rivet rod is made into a hook tooth that can hook the object by external force. It is made of bending, so the hook teeth are easy to break. In order to avoid the cracking of the riveted items caused by the breakage of the hook teeth of the riveting cylinder, bolts are basically used for high-strength connections. However, there are many procedures for bolt connections, complicated operations, and labor-intensive Time-consuming, and on some equipment with vibration, the vibration will cause the bolts to loosen easily, so a variety of anti-loosening measures will be taken, but the anti-loosening methods adopted will increase the cost of use, and the second is that the anti-loosening measures often fail, so The equipment fixed by bolts requires frequent repair and maintenance, which wastes a lot of manpower and material resources; in order to solve the above problems, the present invention proposes an elastic hook pin device
