Abstract
The utility model relates to an efficient motor-driven grease gun which comprises a shell body, a plunger pump mechanism, a slider-crank mechanism, a gear reducer mechanism, an oil supply system and a power system. The power system drives the gear reducer mechanism to move, and the slider-crank mechanism comprises a crank and a slide block. The crank is arranged on an output shaft of the gear reducer mechanism, and the slide block is connected with the plunger pump mechanism. A slide groove matched with the slide block is arranged on the shell body, and an arc-shaped through groove is arranged on the slide block. A pin shaft which can move in the arc-shaped through groove is arranged on the crank. Through utilization of the arc-shaped through groove, the slide block is enabled to keep quite high speed at the second half stroke from bottom to top, namely average speed of the second half stroke is improved. Therefore, air is effectively prevented from flowing back, and air in a cylinder can be effectively exhausted, air resistance caused by bubbles in grease can not occur, so the grease gun idles and can not exhaust the air, efficiency of grease extrusion is greatly improved, and pressure and flow speed of a grease pump are increased.
Description
Technical field
The utility model relates to the grease oiling device technical field, especially a kind of efficient electric grease gun.
Background technique
Grease gun is a kind of hand-operated tools to the machinery grease up, it can select dress iron barral of a gun (iron rifle head) or flexible pipe (flat rifle head) zerk, convenient to refueling position, as to be in the space spaciousness local available iron barral of a gun (iron rifle head), place hidden to refueling position, that talk in a roundabout way just must be refueled with flexible pipe (flat rifle head).Grease gun has simple to operate, and is easy to carry, the plurality of advantages that using scope is wide, and grease gun has the variety classeses such as Pneumatic grease gun, hand grease gun, foot-operated grease gun, electric grease gun.
Electric grease gun is used widely because of its portability, high efficiency, disclose a kind of micro electric grease gun such as Chinese patent CN200620043459.0, be made of housing, frame, plunger pump mechanism, slidercrank mechanism, reduction gears mechanism, oil supply system, operation system and power system: its structure is small and exquisite, and battery is built-in, can an external charger, driven by direct current generator, moderate cost, laborsaving, fast, easy to operate, pressure is larger, can satisfy common mechanical oiling requirement.As shown in Figure 3 of the patent, this Figure of description shown in Figure 4, slidercrank mechanism comprises eccentric wheel and slide block 3, offers a straight trough 33 on the slide block 3, has a bearing pin that cooperates with straight trough 33 on the eccentric wheel.This structure is with movable slider to move up and down in chute when eccentric wheel rotates, thereby realize the to-and-fro motion of plunger pump mechanism, because offer straight trough 33 on the slide block 3, the to-and-fro motion that causes slide block is a standard oscillatory movement, the reciprocating velocity amplitude that is plunger pump mechanism is a sinusoidal motion, when can being divided into squeezing from top to bottom, the motion of plunger pushes away butter stroke and recovery stroke from the bottom up, speed is changed from small to big when stroke from top to bottom, after reaching top speed, the neutral position diminishes, until become zero.This speed becomes greatly by sinusoidal curve and diminishes, when plunger was descending, speed was more and more slower the second half section, if in the cylinder gas is arranged this moment, gas can reflux by plunger and cylinder body gap, cause exhaust effect to descend, stroke vapour lock and affect use, and this Motion curves has been done more idle work, efficient is low, and exist and squeeze the low technical problem of thrust, butter can not well be discharged, and pressure is low and flow velocity is slow.
The model utility content
The technical problems to be solved in the utility model is: overcome the slide block that has straight trough in the prior art low because of the pump oil efficient that vapour lock causes, the technical problem that pressure is low, flow velocity is slow, a kind of efficient electric grease gun is provided, and pressure was large when minimizing air-resistance phenomenon realization high effective pump oil and butter pumped, flow velocity is fast.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of efficient electric grease gun, comprise housing, plunger pump mechanism, slidercrank mechanism, reduction gears mechanism, oil supply system and power system, the motion of power system actuation gear reducing gear, described slidercrank mechanism comprises crank and slide block, described crank is installed on the output shaft of reduction gears mechanism, described slide block connects with plunger pump mechanism, has the chute that cooperates with slide block on the described housing, offer an arc-shaped slot on the described slide block, have the bearing pin that can in arc-shaped slot, move on the crank.
Impact when moving for reducing, the radius of the arc-shaped slot on the described slide block is greater than the radius of gyration of bearing pin.
The most preferred, the radius of described arc-shaped slot is more than 2 times of the radius of gyration of bearing pin.
For ease of dismounting, described crank is threaded with bearing pin.Bearing pin is that the friction of receiving is more in motion, is attrition component, the conveniently replacing after wearing and tearing.
Be to simplify the structure of plunger and slide block, described plunger pump mechanism has a plunger, and the head of plunger has an attachment cap, has a draw-in groove that cooperates with attachment cap on the slide block.
The beneficial effects of the utility model are, efficient electric grease gun of the present utility model is by adopting arc-shaped slot to make slide block still keep higher speed at the lower half way of stroke from top to bottom, namely improved the mean velocity of time half way, effectively like this avoid gas backstreaming, gas in the cylinder also can effectively be discharged, so just can not cause vapour lock because of in the butter bubble being arranged, make grease gun idle running and can't discharge air, greatly improved and squeezed the efficient that pushes away butter, the time butter when pumping pressure increase, flow velocity increases.
