As shown in fig. 1-4, a manual oil pump includes: pump body shell 7 and the oil pumping subassembly that stretches into in the pump body shell 7, establish first check valve 8 in the oil inlet of pump body shell 7, it is preferred, first check valve 8 includes the plectane, the plectane diameter is greater than the oil inlet internal diameter, the plectane centre of a circle sets up thin round rod towards oil inlet outside direction, the plectane is connected to thin round rod one end, one end circumference sets up the arch, the spacing ring is established to the cover on the thin round rod between arch and the plectane, the spacing ring passes through the connecting rod and is fixed with the oil inlet, make spacing ring and oil inlet form spacingly in two directions about in certain extent to first check valve 8, form the check valve device, the oil pumping subassembly comprises the peripheral fixed sealing washer 64 of second check valve 6 and second check valve 6 of 5 end fixing of sucker rod that stretch into in the pump body shell 7.

The second check valve 6 is composed of a valve plate 51 fixed at one end of the sucker rod 5 and a support frame sleeved on the sucker rod, a valve ring 62 matched with the valve plate 51 is arranged on the outer side of the support frame, a sliding sleeve 61 sleeved on the sucker rod 5 is connected and connected in the valve ring 62 through a support, and the sliding sleeve 61 is connected with the sucker rod 5 in a sliding manner and used for supporting a gap between the support frames of the valve ring 62 to form a channel of the second check valve 6.

The valve plate 51 is a circular plate, the lower side of the periphery of the valve ring 62 is provided with a limiting sleeve 63 matched with the valve plate 51, and preferably, the inner diameter of the limiting sleeve 63 is equal to the outer diameter of the valve plate 51, so that the limiting sleeve 63 can be sleeved on the valve plate 51.

The sucker rod 5 is provided with a limit groove above the part matched with the sliding sleeve 61, so that the sliding sleeve 61 can only slide in a certain range above the valve plate 51 of the sucker rod 5.

The upper end of the pump body shell 7 is provided with a sealing cover 9, the sucker rod 5 penetrates through the sealing cover 9, a second sealing ring is arranged between the sucker rod 5 and the sealing cover 9, an oil outlet is arranged on the sealing cover 9, preferably, the oil outlet is connected with one end of the oil pumping pipe 2, the other end of the oil pumping pipe 2 faces the outside, and an oil outlet pipe cover 21 is arranged at an outlet at the outside.

The sealing cover 9 is hinged with one end of a connecting rod 41, the other end of the connecting rod 41 is hinged with a handle plate 4, and the handle plate 4 is hinged with the other end of the sucker rod 5, so that the sealing cover 9, the connecting rod 51, the handle plate 4 and the sucker rod 5 form a connecting rod sliding block mechanism.

The pump casing 7 is externally provided with a decorative sleeve 1, the decorative sleeve 1 is formed by two opposite fixed decorative parts, a limiting groove matched with the cylinder part of the pump casing 7 is formed in the decorative part, the limiting groove is formed by limiting rings 11 with upper and lower sides protruding inwards, after the two decorative parts are fixed, the limiting sleeve is formed by the limiting rings 11 in the inner part, and the pump casing 7 and the sealing cover 9 are clamped and fixed by the limiting sleeve.

The working process of the utility model is as follows: the handle plate 4 is pressed downwards, the connecting rod slider mechanism formed by the sealing cover 9, the connecting rod 51, the handle plate 4 and the sucker rod 5 drives the sucker rod 5 to lift, the air pressure in the cavity between the second one-way valve 6 and the first one-way valve 8 is reduced, the first one-way valve 8 is lifted and pumps oil into the cavity, and the work of pressing or lifting the handle plate 4 is labor-saving according to the lever principle.

Go up handle board 4, drive sucker rod 5 and push down, the clearance appears with the support frame part in valve plate 51 of second check valve 6 to because be equipped with the spacing groove on sucker rod 5, the support frame part can not break away from valve plate 51 too far, in fluid flows into the cavity between second check valve 6 and the sealed lid 9 naturally from the gap.

The handle plate 4 is pressed downwards again to drive the sucker rod 5 to lift, so that oil in the cavity between the second one-way valve 6 and the sealing cover 9 is pumped out through the oil outlet formed in the sealing cover 9 and the oil pumping pipe 2.

When needing a small amount of, when ration take out fluid, can pull out oil extraction pipe from being pumped in the case at any time, remaining fluid in the pump casing 7 still can be through carrying, pressing handle board 4 will be taken out fluid, and because the last step of taking out fluid is to carry out fluid from the cavity between second check valve 6 and the sealed lid 9 in, do not relate to atmospheric pressure and extrude fluid for the user can be better carry out the ration to the volume of pumping, can not appear because of pressure difference problem lead to the problem that how often time is fast time slow when the volume of producing oil.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
