Abstract

The utility model provides a portable grease supply device, which comprises a shell, a motor, a speed reducer, a lead screw, a grease cylinder, a squeezing block and an oil nozzle, wherein the motor and the speed reducer are arranged in the shell; the motor drives the lead screw to rotate through the speed reducer; the shell is fixedly connected with the bottom end of the grease cylinder; the lead screw is inserted into the grease cylinder and is in threaded connection with the squeezing block in the grease cylinder; a seal ring is arranged between the squeezing block and the grease cylinder; and the oil nozzle is fixed at an outlet end of the grease cylinder. Since the oil nozzle can be conveniently replaced, high practicability and universality are guaranteed and lubricating oil can be added to mechanisms with revolving pairs such as gears, chains, bearings and the like; and a self-contained storage battery of machinery can be adopted to supply power for equipment, an alternating current power supply can also be connected to directly supply power for the device, and the device is convenient to carry.

Description

A kind of portable grease supplier

Technical field

The utility model relates to mechanical field, is specially a kind of portable grease supplier.

Background technique

Lubricated component are the indispensable work of mechanical field, use wider interpolation lube plant at present and be lubricated oil can, this device needs external air compressor, with pressurized air is the power resources of whole system, air compressor injects lubricated oil can with pressurized air, extruding lubricant oil flows out from oil outlet, and entering needs lubricated gap location.But this device uses trouble, thereby has the 4S shop or the large enterprise that mostly are the specialized maintenance machinery of this oil-filling device.But the life time of the lubricant oil of annotating is relevant with the Environmental Conditions of machinery, this makes us add lubricant oil and often becomes untimely, often work in the open air as major works equipment, wind and weather, also frequent and mud sandstone stir together, or the like, these have all quickened the consumption of lubricant oil.And field work is not easy in time add lubricant oil away from the maintenance station, thereby has increased mechanical wearing and tearing, makes troubles also for the normal operation of machinery.Therefore be badly in need of a kind ofly can satisfying the device that portable, cheap, easy to operate interpolation lubricant oil requires.

Summary of the invention

The technical problem that solves

Add the deficiency of lubricant oil method in order to solve tradition, the utility model proposes a kind of portable grease supplier.

Technological scheme

The technical solution of the utility model is:

Described a kind of portable grease supplier is characterized in that: comprise housing, motor, retarder, leading screw, grease tube, extrusion block and fuel filler neck; Motor and retarder are installed in the housing, and motor drives leading screw by retarder and rotates; Housing is fixedlyed connected with grease tube bottom, and leading screw inserts in the grease tube, and is threaded with extrusion block in the grease tube, between extrusion block and grease tube seal ring is housed; Grease tube outlet end is fixed with fuel filler neck.

A preferred version of the present utility model is characterized in that: fuel filler neck is the taper fuel filler neck, and tank filler sleeve is from the straight-through outer end of fuel filler neck inner end.

A preferred version of the present utility model is characterized in that: fuel filler neck is the scopiform fuel filler neck, and the fuel filler neck outer end is a flat mouthful of shovel structure, and the fuel filler neck peripheral side is fixed with scrub-brush, and tank filler sleeve is from the logical fuel filler neck peripheral side of fuel filler neck inner end.

Beneficial effect

The utility model is compared with conventional lubrication oil adding set has following feature and advantage:

1, simple in structure, easy to operate, because fuel filler neck can be convenient for changing, practicability and highly versatile can be mechanism's interpolation lubricant oil that gear, chain, bearing etc. have revolute pair;

2, have low in power consumption, the storage battery that can adopt machinery to carry is a power devices, but the incoming transport power supply is directly powered to device again;

3, have portable characteristics, equipment investment is little, and is easy to use, and having alleviated a large amount of labour of engineering machinery personnel and machine repair personnel also provides convenience for common machinery owner or private car owner maintain machinery;

Fig. 2: the structural representation of taper fuel filler neck;

Wherein: 1, motor; 2, one-level reduction gear; 3, double-reduction gear; 4, scopiform fuel filler neck; 5, controller; 6, extrusion block; 7 seal rings; 8, leading screw; 9; The grease tube.

Embodiment

Below in conjunction with specific embodiment the utility model is described:

Embodiment:

Portable grease supplier in the present embodiment comprises: housing, motor 1, retarder, leading screw 8, grease tube 9, extrusion block 6 and fuel filler neck.The bottom of housing and grease tube 9 is bolted to connection.

Motor 1 and retarder are installed in the housing.Motor 1 is the power resources of whole device, employing be the middle electric motor with speed of 12V 20W.Because it is the voltage of the storage battery that self had of machinery generally also is 12V,, easy to use so motor 1 can be by the self-contained storage battery power supply of machinery.

In the present embodiment, retarder adopts secondary gear reducer, and the output of motor 1 is transferred on the leading screw 8 by one-level reduction gear 2 and double-reduction gear 3.Leading screw 8 is as transmission device, and the one step bearing is fixed on the housing inner side surface, and the other end inserts in the grease tube 9, is threaded with extrusion block 6, and rotatablely moving of leading screw 8 is converted to the straight line motion of extrusion block 6.

In order to adapt to various greases, upwards be fixed with seal ring 7 in 6 weeks of extrusion block, be used for extrusion block 6 and grease tube 9 inner wall sealings, stiffening rib is arranged around these external extrusion block 6 middle part tapped holes, increase the intensity of extrusion block.Extrusion block 6 is driven in 9 motions of grease tube by leading screw 8, and leading screw 8 is driven by motor 1, so the rotating speed of motor 1 has determined the extruding force of extrusion block 6.According to the difference of grease, the extruding force size that needs extrusion block 6 to produce is also different, and controller 5 links to each other with motor 1 by signaling line, the rotating speed of control motor 1, thus make extrusion block 6 produce required extruding force.

Grease tube 9 outlet end are fixedlyed connected with the fuel filler neck screw thread, and different fuel filler necks is selected at the position of refueling as required for use.Make and can adopt the taper fuel filler neck for bearing, nut, gear, revolute pair interpolation lubricant oil, taper fuel filler neck oil outlet end is taper, and tank filler sleeve is from the straight-through outer end of fuel filler neck inner end.Giving exposed frequent and water, the gear of adhesiveness materials such as dust contact, when chain and revolute pair are added lubricant oil, can adopt scopiform fuel filler neck 4, scopiform fuel filler neck 4 outer ends are flat mouthful of shovel structure, being used for scoop uses, root out to stick to and need lubricating structure bur on every side, scopiform fuel filler neck 4 peripheral side are fixed with scrub-brush, can further play the effect of cleaning, tank filler sleeve is from the logical fuel filler neck peripheral side of fuel filler neck inner end simultaneously, be that the tank filler sleeve outlet is positioned at the scrub-brush root, when lubricated, lubricant oil flows out from tank filler sleeve, with the scrub-brush brush, it is more even that lubricant oil is added on one side for lubricating oil filling on one side.
