Description

Technical Field

[0001] The utility model relates to the technical field of chain pins, in particular to a hollow pin for a conveyor chain. Background Art

[0002] A chain is generally a metal link or ring, mostly used for mechanical transmission and traction. A chain-shaped object used to block a traffic passage, such as in a street, a river or a harbor entrance, and a chain used for mechanical transmission. Most chains are composed of components such as chain plates, chain pins and bushings. The chain is widely used in various machines. When the chain is applied to a conveyor, it is necessary to convey an object.

[0003] During the conveying process, the outer chain plate and the inner chain plate are prone to friction with each other. And when conveying a heavier object, the bearing capacity of the chain is large, resulting in an increase in the friction coefficient between the outer chain plate and the inner chain plate, which makes the outer chain plate and the inner chain plate prone to damage, and thus the chain breaks, which will affect the subsequent object conveying. Therefore, those skilled in the art provide a hollow pin for a conveyor chain to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hollow pin for a conveyor chain to solve the problems raised in the above background art.

Two spacer rings are sleeved on the outside of each of the two pin bodies. Two inner chain plates are sleeved on the outside of each of the two pin bodies. Two outer chain plates are sleeved on the outside of each of the two pin bodies. Rollers are sleeved on the outside of each of the two pin bodies. Positioning tubes are threadedly connected to the outer surfaces of the two pin bodies.

[0007] As a further scheme of the utility model: Anticorrosion layers are fixedly connected to the outer surfaces of the two pin bodies, and the two anticorrosion layers are electro-galvanized layers.

[0008] As a further scheme of the utility model: External threads are provided on the outer surfaces of the two pin bodies, and internal threads are provided on the inner walls of the two positioning tubes.

[0009] As a further scheme of the utility model: Each spacer ring is located between the inner chain plate and the outer chain plate, and a lubricating paint surface is sprayed on the outer surface of each spacer ring.

[0012] As a further solution of the utility model: The two rollers are each adapted to the pin shaft body, and the diameter of each positioning tube is greater than the diameter of the pin shaft body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] For the hollow pin shaft of the conveyor chain, through the cooperation of the partition plate and the anti-corrosion layer, not only can the pin shaft body have an anti-corrosion effect, but also the service life of the inner link plates and the outer link plates is greatly increased. Through the settings of the external thread, threaded hole, positioning tube, round plate, positioning hole, internal thread and positioning screw, not only can people disassemble and assemble the pin shaft body, but also the stability of the roller is greatly increased, preventing the outer link plate from falling off during the working process.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.

[0023] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, a hollow pin shaft for a conveyor chain includes two pin shaft bodies 1. Baffles 2 are fixedly connected to the outer surfaces of the two pin shaft bodies 1. Two spacer rings 3 are sleeved outside the two pin shaft bodies 1. Two inner link plates 4 are sleeved outside the two pin shaft bodies 1. Two outer link plates 5 are sleeved outside the two pin shaft bodies 1. Rollers 6 are sleeved outside the two pin shaft bodies 1. Positioning tubes 10 are threadedly connected to the outer surfaces of the two pin shaft bodies 1, which can make the wear resistance effect of the device better, greatly increase the service life of the chain, and thus solve the problem that during the conveying process, the outer link plate 5 and the inner link plate 4 are prone to rubbing against each other, and when conveying heavier objects, the bearing capacity of the chain is large, resulting in an increase in the friction coefficient between the outer link plate 5 and the inner link plate 4, causing the outer link plate 5 and the inner link plate 4 to be easily damaged, resulting in the chain breaking and affecting the subsequent object conveying.

[0024] Anti-corrosion layers 7 are fixedly connected to the outer surfaces of both pin shaft bodies 1. The two anti-corrosion layers 7 are electro-galvanized layers. External threads 8 are provided on the outer surfaces of both pin shaft bodies 1. Internal threads 13 are provided on the inner walls of both positioning tubes 10. Each spacer ring 3 is located between the inner link plate 4 and the outer link plate 5. A lubricating paint surface is sprayed on the outer surface of each spacer ring 3, which can not only prevent the outer surface of the pin shaft body 1 from rusting after long-term use, but also make the wear resistance of the chain better.

[0025] Two threaded holes 9 are provided on the outer surfaces of both pin shaft bodies 1. Circular plates 11 are fixedly connected to the backs of both positioning tubes 10. Two positioning holes 12 are provided on the outer surfaces of both positioning tubes 10. A positioning screw 14 is threadedly connected to the inner wall of each positioning hole 12. Both rollers 6 are adapted to the pin shaft body 1. The diameter of each positioning tube 10 is larger than the diameter of the pin shaft body 1, which can not only enable people to disassemble and assemble the chain, but also greatly increase the stability of the chain.

[0026] The working principle of the present utility model is as follows: First, people can respectively sleeved the inner link plate 4, the outer link plate 5, the roller 6 and the spacer ring 3 on the outside of the pin shaft body 1. The spacer ring 3 is sleeved between the inner link plate 4 and the outer link plate 5. Then, the positioning tube 10 can be installed by using the internal thread 13 and the external thread 8. After the positioning tube 10 is installed, the positioning screw 14 can be installed into the positioning hole 12 and the threaded hole 9 to position the positioning tube 10. The anti-corrosion layer 7 can prevent the outer surface of the pin shaft body 1 from rusting. During the working process of the chain, the spacer ring 3 can separate the inner link plate 4 and the outer link plate 5 to prevent the inner link plate 4 and the outer link plate 5 from rubbing against each other during the working process and thus breaking.
