Description

Technical Field

[0001] The invention belongs to the field of machinery, and in particular relates to an elastic hook pin device. Background Art

[0002] At present, rivets are commonly used parts for connecting two objects. Commonly used rivets are composed of rivet barrels. Since the rivet barrels have no curling and rebounding function, during riveting, the rivets use their own deformation or interference to connect the riveted parts. Therefore, the rivet barrels can only be made relatively thin, resulting in poor rivet strength. In order to facilitate the end of the rivet barrel to pass through the riveted object, the end of the rivet rod is made into a hook tooth that can hook the object by external force. Since the hook tooth is formed by bending, the hook tooth is easy to break at the bending part. In order to avoid the riveted object from cracking due to the breakage of the rivet barrel hook tooth, high-strength connections are basically connected by bolts. However, the bolt connection process is more, the operation is complicated, and it is labor-intensive and time-consuming. In addition, on some equipment with vibration, vibration may cause the bolts to loosen easily. Therefore, a variety of anti-loosening measures are taken. However, the anti-loosening means adopted increase the use cost and the anti-loosening measures often fail. Therefore, the equipment connected and fixed by bolts needs to be frequently repaired and maintained, wasting a lot of manpower and material resources. In order to solve the above problems, the present invention proposes an elastic hook pin device. Utility Model Content

[0003] The present invention is achieved through the following technical solutions:

[0004] An elastic hook pin device comprises an elastic buckle pin, a conveyor belt, a chain connecting the conveyor belt, and a driving chain.

[0005] The conveyor belt is provided with a groove or a groove hole for placing the side buckle parts. The side buckle parts are arranged in the side buckle part grooves, or the side buckle parts and the fixed buckle sprocket shaft parts are arranged. The conveyor belt is connected and fixed to the side buckle parts through elastic buckle pins, or the conveyor belt is connected and fixed to the side buckle parts and the fixed buckle sprocket shaft parts through elastic buckle pins; the drive chain and the chain-connected conveyor belt parts are separately connected or integrated.

[0006] The elastic buckle pin adopts an elastic hook pin or a spring buckle rivet or a non-return spring hook pin, including a metal elastic buckle pin or a plastic elastic buckle pin or a ceramic elastic buckle pin.

[0007] The conveyor belt includes a side guard belt or a flat-edge conveyor belt: the side guard belt includes a belt side guard and a joint side guard belt, the belt side guard is arranged on one side or both sides of the joint side guard belt, the roller chain flat baffle is separately connected to the belt side guard or is integrated, the roller chain flat baffle is connected to the belt side guard through a chain-connected conveyor belt member, or the joint side guard belt is connected to the drive chain through a chain-connected conveyor belt member, or the roller chain conveyor belt plate is connected to the conveyor belt through a chain-connected conveyor belt member.

[0008] The driving chain adopts a roller chain or annular chain. The roller chain comprises a roller chain buckle plate and a roller chain shaft.

[0009] The conveyor belt includes a chain belt side baffle, which is arranged on the side of the conveyor belt or on the roller chain shaft. The chain belt side baffle includes a side embedded baffle or a side through-shaft baffle. The roller chain buckle plate is provided with a material baffle plate. When the material baffle plate moves toward the inside of the conveyor belt, the chain belt side baffle blocks the roller chain buckle plate from moving toward the inside of the conveyor belt. The material baffle plate blocks the material from flowing out from the side of the material baffle plate. The chain belt side baffle blocks the conveyor belt from moving left and right, preventing the conveyor belt from moving left and right to shear the chain connecting the conveyor belt parts.

[0010] The beneficial effects of the present invention are as follows: the structural performance defects of the old rivets, such as the rivet barrel having no curling and rebounding function and the poor rivet strength, are changed; the elastic buckle pin can be used on large buckles and in harsh environments, avoiding the use of screws and nuts to connect the objects to be riveted, which are easy to unthread and fall off, resulting in the unusable machines on site and the need for frequent repairs and maintenance, which causes a lot of manpower and material resources to be wasted; the structure and performance of the old elastic pins, which are only used as stop pins and cannot be used as connecting parts, are changed, so that the elastic hook pin has the function of blocking the left and right and up and down movement of objects, and has the function of fitting different objects up and down and / or left and right; when subjected to vibration and pulling, the elastic buckle pin will not unthread or fall off; the installation is quick and durable, with fewer parts, low manufacturing cost, long service life, and high safety performance; a lot of manpower and material resources are saved, and the comprehensive safety performance and use efficiency of the equipment are improved.
