AI Technical Summary
The existing anti-leakage oil pump is laborious and has great losses when screwing into the screw rod to the internal threaded pipe, and cannot be completely screwed in, making it poor practicality.
The double-sided rack and multiple gears are meshed and connected. The third and second gears drive the double-sided rack to rotate, increase the force point, reduce gear loss, and form a force arm through the connecting rod and handle to reduce screwing time strength.
The practicality of the oil pump is improved, and by dispersing the gear stress points and forming the force arm, a more labor-saving screw threading operation is achieved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engine oil pumps, in particular to an anti-leakage engine oil pump. Background Art
[0002] As we all know, the oil pump is a component used to increase the oil pressure and ensure a certain amount of oil, and to force the oil to be supplied to each friction surface. The oil pump structure can be divided into two types: gear type and rotor type. Gear type oil pumps are further divided into internal gear type and external gear type. The latter is generally called gear type oil pump. The performance of the sealing cover of an oil pump directly affects the working performance of the oil pump.
[0003] The patent with application number CN202320964725.7 discloses an anti-leakage oil pump, which relates to the technical field of oil pumps, including a pump body and a pump cover, one end of the pump body is fixedly sleeved with an annular plate, the side wall of the annular plate is fixedly connected with four internally threaded tubes, the interior of the pump cover is rotatably connected with four screw rods, each of the screw rods is threadedly sleeved with the inner wall of the corresponding internally threaded tube, a driving mechanism is arranged inside the pump cover, the rod wall of each screw rod is fixedly sleeved with a first gear, and each of the first gears is transmission connected to the driving mechanism.
[0004] Although the device has the effect of driving four screw rods to rotate at the same time, the device drives the four first gears to rotate through the meshing of the second gear in the middle, thereby driving the screw rods to enter the internal threaded tube. This screwing method is more laborious, and the first gear and the second gear have only one meshing point. In order to quickly screw several screw rods into the internal threaded tube, it takes a lot of effort, and the loss of the first gear is relatively large. Secondly, the device has force storage devices such as torsion springs, but it is impossible to completely screw the screw rods into the internal threaded tube. Therefore, the practicality is not very good and there is still room for improvement. Utility Model Content

[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides an anti-leakage oil pump, which has the following beneficial effects:
[0016] The anti-leakage oil pump uses several double-sided racks to mesh the first gear together to increase the contact area, and then drives several second gears to rotate through the third gear, and drives the double-sided racks to rotate through the second gear, thereby increasing the force points of the third gear and the second gear, and to a certain extent disperses the overall force of the third gear and the second gear directly acting on one point, thereby reducing certain losses, and finally, through the setting of the connecting rod and the handle, a longer force arm is formed for the screw in the pump body cover, which can save effort when turning the handle.
