Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in figures 1 to 6, it is a kind of hand pump of the utility model, which includes the pump housing 1 and be hinged with the pump housing 1
Rocking bar 2, be both provided with oil outlet 11 on the opposite sides face of the pump housing 1, be both provided in these oil outlets 11 and flow for liquid
Go out the first check valve 111 of the pump housing 1, which is provided with oil mirror hole on the side perpendicular with the side equipped with oil outlet 11
12, the pump housing 1 is interior to be equipped with the fluid infusion hole 13 parallel with oil mirror hole 12, is provided in the fluid infusion hole 13 and enters the pump housing 1 for liquid
The second interior check valve 131, the axis in the oil mirror hole 12 and fluid infusion hole 13 on the same line, to observe oil mass, the oil mirror
The aperture in the aperture ratio fluid infusion hole 13 in hole 12 is big, facilitates processing fluid infusion hole 13, which is equipped with hinge close to one end of oil outlet 11
Joint chair 14, the hinged seat 14 are extended downwardly by one end of the pump housing 1, by hinged seat 14 and 1 integrally casting shaping of the pump housing, so as to
The use of corresponding connecting elements is reduced, simplifies the overall structure of hand pump, production cost is reduced, oil is additionally provided in the pump housing 1
Case 15, the pump housing 1 and 15 integrally casting shaping of fuel tank, by by the pump housing 1 and 15 integrally casting shaping of fuel tank, making the system of hand pump
It makes technique and installation procedure is simplified, be simplified the overall structure of hand pump while reducing hand pump cost, the oil
Case 15 is communicated with fluid infusion hole 13, and rocking bar 2 is rotatably connected by pin 21 and the realization of hinged seat 14, which is equipped with groove
141, to place pushing cylinder 3, spring 31 is provided in the pushing cylinder 3, the bottom of the groove 141 is equipped with sprocket hole 1411, the conveying
Hole 1411 is connected with each oil outlet 11 and fluid infusion hole 13, to realize the conveying of liquid.
A kind of operation principle of hand pump of the utility model is as follows：As shown in figure 5, when pulling rocking bar 2 counterclockwise, pushing cylinder
3 move down under the elastic force effect of spring 31, and under the action of pressure difference, the lubricating oil in fuel tank 15 is from fluid infusion hole 13 by defeated
Hole 1411 is sent to enter in groove 141, due to being both provided in oil outlet 11 and 131 direction of the second check valve in fluid infusion hole 13
The first opposite check valve 111, therefore lubricating oil can only enter in groove 141；As shown in fig. 6, when pulling rocking bar 2 clockwise, push away
