Abstract
The utility model discloses a sprocket used for a filing cabinet, which comprises a small sprocket and a large sprocket, wherein the small sprocket and the large sprocket are integrally formed, sprocket mounting axle holes are positioned in the middle of the small sprocket and the large sprocket, and a sprocket groove is formed between the small sprocket and the large sprocket. The sprocket used for the filing cabinet is integrally formed by plastic, has the advantages of firm integral structure, low production cost, easy mass production, rustless property and light weight; and bearings are installed in the sprocket mounting axle holes conveniently, and mechanical wear in rotation of the sprocket is reduced.
Description
Technical field
The utility model belongs to the sprocket wheel technical field, especially relates to a kind of filling cabinet sprocket wheel.
Background technique
At present, the sprocket wheel that filling cabinet is used uses metal forging processing, during production, forges minor sprocket and hinge wheel earlier, minor sprocket and hinge wheel is welded together make the filling cabinet sprocket wheel then.The filling cabinet of producing like this with sprocket wheel have the cost of production height, be difficult for producing, easily get rusty, the easy shortcoming such as disconnection of Heavy Weight, weld, so be necessary to be improved.
The model utility content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides that a kind of integral body is firm, cost of production is low, is easy to production in enormous quantities, non-corrosive, lightweight filling cabinet sprocket wheel.
To achieve these goals, the technological scheme that the utility model adopted is: the filling cabinet sprocket wheel, constitute by minor sprocket and hinge wheel, and described minor sprocket and hinge wheel are made of one piece, the sprocket wheel installation axle hole is positioned at the middle part of minor sprocket and hinge wheel, forms sprocket groove between minor sprocket and hinge wheel.
Described sprocket wheel installation axle hole is made of preceding sector hole, middle sector hole and back sector hole, preceding sector hole and back sector hole be symmetrically distributed in two limits of sector hole, the diameter of preceding sector hole and back sector hole is identical and greater than the diameter of middle sector hole, preceding sector hole and after bearing is installed on the sector hole.
Described filling cabinet adopts integrally moulded with sprocket wheel.
The utility model is compared the advantage that is had with prior art: filling cabinet adopts integrally moulded with sprocket wheel, have whole firmly, cost of production is low, be easy to production in enormous quantities, non-corrosive, lightweight advantage; The sprocket wheel installation axle hole is convenient to install bearing, reduces the mechanical wear of sprocket rotation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see shown in Figure 1: the filling cabinet sprocket wheel, constitute by minor sprocket 1 and hinge wheel 2, minor sprocket 1 and hinge wheel 2 adopt integrally moulded forming, sprocket wheel installation axle hole 3 is positioned at the middle part of minor sprocket 1 and hinge wheel 2, and 2 of minor sprocket 1 and hinge wheels form sprocket groove 4.Sprocket wheel installation axle hole 3 is made of preceding sector hole 31, middle sector hole 32 and back sector hole 33, preceding sector hole 31 and back sector hole 33 are two limits that are symmetrically distributed in middle sector hole 32, before the sector hole 31 and afterwards diameter of sector hole 33 is identical and greater than the diameter of middle sector hole 32, on preceding sector hole 31 and the back sector hole 33 bearing is installed, bearing can reduce the mechanical wear of sprocket rotation.
