Description
Technical Field
[0001] The utility model belongs to the technical field of sprocket structures, and particularly relates to a sprocket structure convenient for maintenance. Background Art
[0002] A sprocket is a wheel with toothed chain engaging teeth, used to engage with pitch-accurate blocks on a chain link or cable. Sprockets are widely used in mechanical transmissions in industries such as chemical engineering, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, and petroleum.
[0003] The existing sprocket structures on the market have the following problems when applied:
[0004] 1. When repairing traditional sprocket structures, it is generally necessary to first remove them. During disassembly, it is necessary to strike both sides of the sprocket to remove it. Since the exposed area on the side of the sprocket is small, it is difficult to accurately strike the sprocket body, making it difficult to remove it for repair.
[0005] 2. When traditional sprocket structures are in use, due to long-term use, more impurities and oil stains are likely to adhere to their surfaces, which is likely to increase their friction and affect the use of the sprocket. Moreover, when cleaning, the entire sprocket needs to be removed, making it very inconvenient to clean. Content of the Utility Model
[0006] The purpose of the utility model is to provide a sprocket structure convenient for maintenance to solve the technical problems raised in the background art.
[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A sprocket structure convenient for maintenance, on the surface of the sprocket body, there are a first fixing ring and a second fixing ring. On the sides of the first fixing ring and the second fixing ring, there are knock plates fixedly connected, and the knock plates are symmetrically distributed. On the surface of the first fixing ring, there is a first mounting plate fixedly connected, and on the surface of the first fixing ring, there is a second mounting plate fixedly connected. On the surface of the first mounting plate, there is a fixing rod fixedly connected, and the fixing rod is inserted into the second mounting plate.
[0008] Preferably, a chute is opened on the side of the sprocket body, and on the surface of the sprocket body, there are scraping plates. The number of scraping plates is two. On the side of the scraping plate, there is a side plate fixedly connected. On the side of the side plate, there is an arc plate fixedly connected. On the surface of the side plate, there is a slider fixedly connected, and the slider is embedded in the chute.
[0009] Preferably, a jack is opened on the surface of the first fixing ring, and on the surface of the second fixing ring, there is an insertion rod fixedly connected, and the insertion rod is inserted into the jack.
[0010] Preferably, on the surfaces of the first fixing ring and the second fixing ring, there are handles fixedly connected, and the number of handles is two.
[0011] Preferably, one end of the fixed rod is fixedly connected to a ball head, and a rubber ring is embedded on the surface of the second mounting plate.
[0012] Preferably, a pull rod is fixedly connected to the surface of the side plate, and the number of the pull rods is two.
