Description
Technical field
The present invention relates to a kind of brake system of forklift, more particularly, to a kind of fork truck braking oilcan.
Background technique
Brake system of forklift will have a direct impact on vehicle as one of most important system of fork truck, the reasonability of design
Safety and reliability.Braking oilcan is one of most important components in brake system of forklift.Brake oil on conventional forklift
Pot is all fixed on master cylinder, however such arrangement not only increases the height of foot pedal, so that the sky of driver's cabin
Between it is relatively crowded, and fork truck bottom because braking oilcan height generate space can not utilize, cause space waste.Cause
This, more and more fork trucks arrange braking oilcan elsewhere, connect braking oilcan and master cylinder using hose.
Existing braking oilcan is made into integration by plastics, however fork truck is engineering truck, sometimes operating condition rather harsh, part
It also needs to adapt to freezer environment, since the structural strength of the oil outlet position of this braking oilcan is low, this braking oilcan
It easily cracks in the presence of a harsh environment.
Summary of the invention

Detachable on the connector mounting hole to be equipped with high-intensitive oil can connector, the oil can shell passes through the oil can
Connector and external hose are connect with fork truck master cylinder.
The oil can connector include the joint body with axial screw hole, the cylinder spout with axial central through hole,
Clamping screw, plain washer with axial central through hole, the cylinder spout integral vertical are set to the joint body
Bottom end on, the bottom end of the cylinder spout is connect with external hose, the clamping screw pass through the plain washer from
The bottom inside of the oil can shell is pierced by the connector mounting hole and is spirally connected with the joint body, makes the connector
Ontology is installed in the bottom outside of the oil can shell, the axial central through hole of the clamping screw, the connector
The axial screw hole of ontology, the cylinder spout axial central through hole be connected to form flow-guiding channel, the flow-guiding channel connects
Lead to inner cavity and the external hose of the oil can shell.Here, joint body is integrally machined with cylinder spout, cylinder spout
Bottom end for connect with external hose, therefore usually the bottom end of cylinder spout is designed as hemispherical, facilitated and external hose
Connection；Clamping screw cooperates plain washer to compress oil can ontology, plays the role of sealing；Clamping screw has been spirally connected with joint body
At the installation of the oil can connector, not only facilitate, but also removable.
It is provided between the top of the joint body and the bottom outside of the oil can shell hydraulic for preventing
The sealing structure that gap of the oil between the top of the joint body and the bottom outside of the oil can shell leaks out.It is close
The setting of seal structure further improves sealing effect.
It annular groove on top of the sealing structure by being set to the joint body and is set to described
O-ring seal composition in annular groove.The structure of this sealing structure is simple and practical.
The joint body is hexagonal body, and the top of the axial central through hole of the clamping screw is hex hole
And lower part is circular hole.It is hex hole by the upper design of the axial central through hole of clamping screw, joint body is designed as six
It is angular so that it is convenient to make clamping screw lock-on connection ontology using die nut.
The fork truck braking oilcan further includes the oil-can lid being covered in the top opening of the oil can shell, the oil
Pot lid offers annular slot radially, and the top opening edge of the oil can shell, which turns up, to be formed with a plane and fix
Ring, the plane fixed ring, which is caught in, realizes the removable of the oil can shell and the oil-can lid in the annular slot
Unload formula connection.Oil-can lid can be used rubber material and be made；Oil can shell is realized using the cooperation of plane fixed ring and annular slot
