Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Example 1

As shown in fig. 1, an improved hand pump comprises a hand pump main valve 2, a hand pump mechanism 7 for manually pumping oil is arranged on the main valve 2, and the hand pump mechanism 7 has the advantages that: when the fuel in the fuel tank is used up, the fuel pump cannot be started, and the fuel needs to be manually pumped into a filter to be used for starting the engine;

the hand pump mechanism 7 comprises a first transverse plate 71 movably connected with the main valve 2, the first transverse plate 71 is connected with the main valve 2 through two supporting points, one supporting point is fixedly connected, the other supporting point is hinged, a second transverse plate 73 is arranged on the outer wall of the main valve 2 installation tank through two expansion springs 72, and the expansion springs 72 are arranged to have a buffering pre-starting process before the hand pump is used and to be beneficial to accurate oil supply; the second transverse plate 73 is provided with a third transverse plate 77 through two telescopic rods 75, the first transverse plate 71, the second transverse plate 73 and the third transverse plate 77 are directly and vertically provided with a screw 76, the telescopic rods 75 are arranged to ensure that the second transverse plate 73 and the third transverse plate 77 can move relatively when the screw 76 rotates, and when the screw 76 moves out of the box abnormally, the telescopic rods 75 can enable the third transverse plate 77 to return to the original position, so that unnecessary damage to the main valve 2 is prevented.

Specifically, the first transverse plate 71, the second transverse plate 73 and the third transverse plate 77 are all arranged in parallel.

Specifically, one end of the screw 76 is movably mounted to the first horizontal plate 71 through a bearing, and a nut 78 that is engaged with the screw 76 to rotate is disposed on the third horizontal plate 77.

Specifically, the other end of the screw 76 passes through a nut 78 and is fixedly mounted with a hand wheel 79 for rotating the screw.

Specifically, the screw 76 has a lead angle between 20 degrees and 40 degrees, and when the screw 76 is rotated, the screw 76 is linearly moved in the axial direction due to the threaded connection between the screw 76 and the nut 78, thereby driving the main valve 2 to perform the manual oil pumping operation.

It should be noted that, firstly, according to the screw transmission theory and the screw pair efficiency curve, the larger the helix angle, the higher the transmission efficiency, and at the same time, the axial force (thrust) is reduced, and the circumferential force is increased (of course, the torque can be changed by adjusting the radius of the hand wheel and the required circumferential force can be provided); when the lead angle is larger than 27 degrees (the trapezoidal thread is different from the rectangular screw), the efficiency is not obviously increased; when the lead angle reaches about 40 degrees, the efficiency of the screw pair is highest, and then the efficiency is reduced. Second, the larger the lead angle, the more difficult it is to manufacture the screw pair. Thirdly, the hand wheel rotates for a circle, the piston moves for a lead, considering that the moving distance of the piston cannot be too small (or too slow), and considering the efficiency, the torque, the thrust and the speed, the range of the thread lead angle is selected to be proper between 20 degrees and 40 degrees.

The utility model provides an integrated assembly of filter tank, includes the filter tank jar body 1, still includes foretell improved generation hand pump, has arranged oil pipe 4 and has advanced oil pipe 5 in the filter tank jar body 1, goes out oil pipe 4 and advances oil pipe 5 and pass through 2 discontinuous intercommunications of main valve, has arranged the discharge valve 6 that is used for balanced filter tank jar body 1 jar internal atmospheric pressure on going out oil pipe 4, goes out oil pipe 4 and advances oil pipe 5 and through 2 discontinuous intercommunications through the main valve, when needing the machine operation, main valve 2 earlier with the fuel from advancing oil pipe 5 pump into the filter.

Specifically, a filter connector 3 is disposed at the bottom of the main valve 2, and the oil inlet pipe 5 is first communicated with the main valve 2 through the filter connector 3.

When the oil pumping device is used, the hand wheel 79 is screwed according to the required oil pumping amount, the hand wheel 79 drives the screw rod 76 to rotate, the screw rod 76 is in threaded connection with the hand wheel 79, the third transverse plate 77 moves relative to the first transverse plate 71 in the rotating process, the expansion spring 72 can have a buffering pre-starting process before the hand pump is used, and therefore the expansion rod 75 can be compressed in the rotating process, when the expansion spring 72 is contracted to the shortest position, the first transverse plate 71 can rotate along a hinge point due to the connection relation between the first transverse plate 71 and the main valve 2, so that the other pivot point of the first transverse plate 71 drives the main valve 2 to pump oil, fuel enters the filter from the oil inlet pipe 5, and then reaches the oil outlet pipe 4 through the main valve, and the oil pumping operation of the hand pump is completed.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
