[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction. Chain-shaped objects used to block traffic passages (such as in streets, rivers or harbor entrances), and chains used for mechanical transmission.

[0003] Based on the above, the inventors have found the following problems: when the chain is used for a long time, it will cause the chain to stretch, and the chain may become loose due to long-term use, and the chain will become loose at this time, and the tooth jumping phenomenon will occur. Generally, an adjustment mechanism is installed on the mechanical chain to adjust the tightness of the chain to prevent it from loosening. This adjustment mechanism needs to be adjusted manually. If the personnel do not notice that the chain is loose, the tooth jumping phenomenon needs to be reinstalled, which is inconvenient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a mechanical chain self-lubricating anti-loosening mechanism is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a mechanical chain self-lubricating anti-loosening mechanism to solve the problem that the current adjustment mechanism needs to be adjusted manually.

[0008] Furthermore, the adjusting sprocket is transmission-connected to the outer side of the chain, and two transmission sprockets are arranged opposite to each other on the inner side of the chain.

[0009] Furthermore, a limiting rod is installed at one end of the central axis, the diameter of the limiting rod is matched with the width of the moving groove, and the limiting rod is located inside the moving groove.

[0010] Furthermore, the pushing mechanism includes a connecting member, a mounting shaft is installed on the connecting member, the connecting member is movably connected to a mounting rod via the mounting shaft, and a spring is arranged on a side of the mounting rod.

[0012] Furthermore, a driving motor is installed in the middle of one of the driving sprockets, the output end of the driving motor is connected to the driving sprocket, and the driving motor is connected to one side of the processing box.

[0013] Furthermore, a lubricating liquid box is provided on the protective shell, a lubricating hole is opened at the lower part of the lubricating liquid box, and the lubricating hole is located at the upper part of the chain.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The spring in the utility model pushes the installation rod to move downward, and when the installation rod moves, the lower connecting piece can be pushed to move through the connecting shaft, and the connecting piece will push the L-shaped adjustment plate to move around the connecting shaft. At this time, the central axis in the middle of the L-shaped adjustment plate moves, driving the limit rod and the adjusting sprocket to move, and the adjusting rod will move inside the moving groove to limit the moving trajectory of the central axis. When the adjusting sprocket moves, it can push a part of the chain to retract inward, so that the stroke of the chain is increased. At this time, the chain will be gradually tightened. This method does not require manual adjustment, and can automatically tighten the chain, which can effectively prevent the chain from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
