Description

Sealing pressure plate structure

Technical Field

The utility model relates to the technical field of pressure plate structures, in particular to a sealing pressure plate structure.

Background

The hydraulic pump is a power element of a hydraulic system, and is driven by an engine or an electric motor, and sucks oil from a hydraulic oil tank to form pressure oil, which is discharged and sent to an executing element. The pressure plate pump that hydraulic pump and pressure plate structure combine to form is used in the play gluey device generally, and the pressure plate structure of present use is after using a period, because wherein be used for sealing the sealed rubber of effect is ageing easily, is inconvenient for changing, consequently leak gas easily, is difficult to guarantee the stability of pressure, influences the defeated gluey effect, therefore needs the periodic replacement of new pressure plate, leads to use cost increase.

Disclosure of Invention

Aiming at the problems that after the existing pressure plate is used for a period of time, the tightness is reduced, the stability of pressure is difficult to guarantee, and the glue conveying effect is influenced, the utility model provides the sealing pressure plate structure, which has better sealing effect and longer use, can ensure the stability of pressure, ensure the glue conveying effect, and can save the use cost.

The technical scheme is as follows: the utility model provides a sealed pressure disk structure, its includes the pressure disk main part, runs through the pressure disk main part is equipped with the connecting seat, and the lower extreme of exhaust pull rod stretches into joint in the connecting seat inner chamber, its characterized in that: the bottom of pressure disk main part is connected annular clamp plate, the outside of pressure disk main part is equipped with outer pressure disk, outer pressure disk pass through annular seal pad and gasket with annular clamp plate can dismantle the connection, the outside cover of outer pressure disk is equipped with the toper sealing washer, wherein the external diameter of annular seal pad is greater than the external diameter of toper sealing washer.

It is further characterized by: two rows of connecting shafts which are circumferentially distributed and fixedly connected are arranged along the bottom of the annular pressing plate, the connecting shafts positioned at the periphery of the annular pressing plate penetrate through the bottoms of the gasket, the annular sealing gasket and the outer pressing plate, the connecting shafts positioned at the inner periphery of the annular pressing plate penetrate through the bottom of the pressing plate main body, and locking nuts are sleeved outside the connecting shafts respectively;

the top of the outer pressure plate is also provided with a dust cover, and the dust cover is fixedly connected with the pressure plate main body through a positioning bolt;

and a sealing ring is further arranged between the bottom of the pressure plate main body and the annular pressure plate.

After having adopted above-mentioned structure, can guarantee the leakproofness of pressure disk when pushing down through the setting of annular packing and toper sealing washer, simultaneously because annular packing and toper sealing washer can dismantle the connection, be convenient for regularly change, consequently can guarantee the stability of pressure disk pressure, guarantee the defeated gluey effect, practiced thrift use cost simultaneously.

Detailed Description

As shown in fig. 1 to 5, a sealing pressure plate structure comprises a pressure plate main body 1, an external hydraulic pump is connected to the opening part of the upper end of the pressure plate main body 1, a connecting seat 2 is arranged on a cylinder body penetrating through the pressure plate main body 1, the lower end of an exhaust pull rod 3 stretches into an inner cavity of the connecting seat 2 to be clamped, an annular pressure plate 4 is connected to the bottom of the pressure plate main body 1, an outer pressure plate 5 is arranged outside the pressure plate main body 1, the outer pressure plate 5 is detachably connected with the annular pressure plate 4 through an annular sealing gasket 6 and a gasket 7, a conical sealing ring 8 is sleeved outside the outer pressure plate 5, the outer diameter of the annular sealing gasket 6 is larger than the outer diameter of the conical sealing ring 8, and the annular sealing gasket 6 and the conical sealing ring 8 are made of rubber or other flexible materials. Through the setting of annular packing 6 and toper sealing washer 8, then can guarantee the leakproofness of pressure disk main part 1 when pushing down, annular packing 6 and toper sealing washer 8 can dismantle the connection simultaneously, so be convenient for regularly change, guarantee product result of use.

Further, two rows of connecting shafts 41 which are circumferentially distributed and fixedly connected are arranged along the bottom of the annular pressing plate 4, the connecting shafts 41 positioned at the periphery of the annular pressing plate 4 upwards penetrate through the bottoms of the gasket 7, the annular sealing gasket 6 and the outer pressing plate 5, the connecting shafts 41 positioned at the inner periphery of the annular pressing plate 4 upwards penetrate through the bottom of the pressing plate main body 1, and locking nuts are sleeved outside the connecting shafts 41 respectively. Through connecting axle 41 on the annular clamp plate 4 respectively with pressure disk main part 1, outer pressure disk 5, annular seal 6 and gasket 7, then the dismouting is convenient, is convenient for change annular seal 6 to last to guarantee pressure disk structure holistic leakproofness.

Further, the top of outer pressure disk 5 still is equipped with shield 9, and shield 9 passes through positioning bolt fixed connection with pressure disk main part 1, through shield 9's setting, can play dustproof effect.

Further, still be equipped with sealing washer 10 between the bottom of pressure disk main part 1 and the annular clamp plate 4, through the setting of sealing washer 10, can further guarantee sealed effect.
