Pulley is a kind of simple leverage tool, uses quite extensively in industrial production, especially in coal industry field, all is applied to pulley in the most equipment.In the production link of coal, because particular job environment of colliery, need to use various snatch blocks, yet the snatch block that uses in the existing colliery, volume ratio are large, weight is large, and the workman copies relatively effort mechanically before use, take longevity of service, affect working efficiency, and the opening of existing pulley is inconvenient, is not easy to install.Therefore, should further improve prior art.
The model utility content
The purpose of this utility model provides a kind of snatch block, to overcome the deficiency of the above-mentioned aspect of existing product.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of snatch block, comprise suspension ring, mainboard and pulley, suspension ring are connected with side guard plate by latch shaft and side guard plate one and are connected, side guard plate one is connected with side guard plate and is connected with pulley by main shaft, side guard plate one respectively by latch shaft and main shaft and movable mainboard two be connected mainboard one and be connected, movable mainboard one is connected with movable mainboard two by pin; Described side guard plate two is connected with mainboard with main shaft by latch shaft respectively, mainboard be connected mainboard one and connect by the high strength hex head bolt, the position cover on the described high strength hex head bolt between mainboard and movable mainboard one has setting sleeve.
The position that described latch shaft is positioned at the mainboard outside is provided with jump ring, and the position that latch shaft is positioned at movable mainboard two outsides is provided with bayonet lock.
Cover has axle sleeve on the described main shaft, and the main shaft two ends are connected with respectively hexagon nut, and described pulley is fixed on the axle sleeve.
The beneficial effects of the utility model are: the utility model is simple in structure, and is with low cost, lightweight, workman carrying and use lightly, and opening is convenient.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described a kind of snatch block of the utility model embodiment;
