Abstract
The utility model relates to an oil injection pump, which comprises a pump body (1), wherein one end of the pump body (1) is connected with an oil inlet (5) and an oil outlet (6) in a penetrating way, the other end of the pump body (1) is connected with a piston rod (2) in the penetrating way, one end, inserted into the pump body (1), of the piston rod (2) is connected with a piston (3), an elastic element (4) is arranged between the piston (3) and the end wall of the pump body (1) which is connected with the oil inlet (5) and the oil outlet (6) in the penetrating way. The oil injection pump has the advantages that the structure is simple, and the manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of filling pump, belongs to oil filling equipment technical field.
Background technique
At present, for machinery, especially rotate the machinery of class, the position rubbing for Mechanical Contact needs regular charging-up lubricant oil to be lubricated, to prevent, because wearing and tearing cause device damage, reducing its working life.For this reason, need to drip lubricant oil to these equipment and be lubricated, the conventional mode of submitting is for manually to drip or to adopt special-purpose Dropping feeder, and still, manual type wastes time and energy, and easily because of operator's carelessness drip, causes potential safety hazard; Special-purpose Dropping feeder complex structure, cost is high, after extensive use, can cause enterprise's cost of production to rise.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure and cheap filling pump is provided.
The purpose of this utility model is achieved in that a kind of filling pump, described filling pump includes the pump housing, one end cross-under of the described pump housing has filler opening and oil outlet, the other end cross-under has a piston rod, described piston rod is inserted to and on the one end in the pump housing, is connected with a piston, and described piston and cross-under have between the pump housing end wall of filler opening and oil outlet and be provided with an elastic element.
A kind of filling pump of the utility model, described elastic element is a spring.
A kind of filling pump of the utility model, is all serially connected with one-way valve on described filler opening and oil outlet.
A kind of filling pump of the utility model, described piston rod is positioned at a roller bearing is installed on the one end outside the pump housing, and the camming surface of the cam of roller bearing and a rotation contacts with rolling.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, easy to use; But also can to piston rod, drive by different modes, increased the use flexibility of this device.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of filling pump of the utility model.
Wherein:
The pump housing 1, piston rod 2, piston 3, elastic element 4, filler opening 5, oil outlet 6, roller bearing 7.
Embodiment
Referring to Fig. 1, a kind of filling pump that the utility model relates to, described filling pump includes the pump housing 1, the described pump housing 1 one end cross-under have described in filler opening 5 and oil outlet 6(on filler opening 5 and oil outlet 6, be all serially connected with one-way valve), the other end cross-under has a piston rod 2, and described piston rod 2 is inserted to and on the one end in the pump housing 1, is connected with a piston 3, and described piston 3 and cross-under have between the pump housing 1 end wall of filler opening 5 and oil outlet 6 and be provided with an elastic element 4, preferably, this elastic element 4 is a spring; Above-mentioned piston rod 2 can directly be driven or be driven by cam by drive unit, when using cam to drive, piston rod 2 is positioned at one end outside the pump housing 1 and the camming surface sliding contact of cam, preferably, described piston rod 2 is positioned at a roller bearing 7 is installed on the one end outside the pump housing 1, and the camming surface of the cam of roller bearing 7 and a rotation contacts with rolling;
The working principle of this patent is:
Can realize the driving to piston rod 2 by following two kinds of modes:
1, direct piston rod 2, while it being moved right when piston rod 2 is exerted pressure, now elastic element 4 is compressed, and compressing lubricant oil oozes from oil outlet 6; Remove the pressure on piston rod 2, piston 3 is moved to the left under the elastic force effect of elastic element 4, the interior formation negative pressure state of the pump housing 1 now, thus lubricant oil is sucked from filler opening 5;
2, can utilize the cam of rotation to drive piston rod, when the roller bearing 7 on piston rod 2 slides into the low spot place of cam, piston 3 is moved to the left under the elastic force effect of elastic element 4, the interior formation negative pressure state of the pump housing 1 now, thus lubricant oil is sucked from filler opening 5; When the roller bearing 7 on piston rod 2 slides into the height point place of cam, piston 3 moves right under the impetus of piston rod 2, thereby compressing lubricant oil oozes from oil outlet 6, can on oil outlet 6, by pipeline, is connected to and be needed the filling point of charging-up lubricant oil place.
It should be noted that: those skilled in the art, according to above-mentioned formation, adopt the driving mode of other types also all within the protection domain of this patent.
