Abstract

The utility model discloses a manual pump, which comprises an outer shell, a plunger, an oil suction valve and an oil drainage valve. The interior end of a rotary shaft is provided with a swash plate on which a micro-radial thrusting bearing is arranged, and the outer end of the rotary shaft is provided with a crank. A bearing assembly is arranged between the rotary shaft and a bush which is arranged in a hole at the right end of the outer shell. The left end of the outer shell is provided with an oil storing chamber, one end of an axial hole in communication therewith is provided with an oil inlet valve, and the other end thereof is provided with a plunger with springs arranged thereon. The drain valve is arranged at the vertical direction of the axial hole. The end part of the plunger props against a ring sheet of the micro-radial thrusting bearing. The manual pump works either in positive rotation or negative rotation. The rotary shaft is provided with a radial thrusting bearing, a needle roller bearing and a radial bearing and rotates flexibly and easily. The end part of the piston of the manual pump props against the ring sheet of the radial thrusting bearing, while the two can rotate with respect to each other with a small friction resistance. A plunger bush is stopped by a baffle plate fixed in the outer shell and can be maintained and replaced conveniently by disassembling the baffle plate.

Description

A kind of hand pump

Technical field

The utility model relates to a kind of hand pump.

Background technique

Hand pump is made up of the pump housing, plunger, handle, oiling valve and draining valve at present.Handle handle and drive the plunger to-and-fro motion, oiling valve is oil suction in oil sump, drives various mechanical work by the draining valve pressure oil output after the pressurization of axle plug.But volume is bigger, relatively requires great effort, and efficient is lower.

Summary of the invention

The purpose of this utility model is to provide a kind of hand pump for overcoming above-mentioned deficiency.Flexibly, laborsaving.

The utility model is achieved through the following technical solutions.A kind of hand pump comprises shell, plunger, oil sucting valve and draining valve; The inner end of rotating shaft is provided with swash plate, and miniature radial thrust bearing is installed on the swash plate, and crank is equipped with in the outer end of rotating shaft; Rotating shaft and shaft room are equipped with bearing unit, and axle sleeve is contained in the hole of shell right-hand member; The left end of shell is provided with shoe cream room, and axial bore one end that is communicated with shoe cream room is put into fuel tap, and the other end dress plunger is equipped with Returnning spring on the plunger; Draining valve is arranged on the Vertical direction in aforementioned axial hole; The end roof pressure of plunger is on the ring plate of miniature radial thrust bearing.

The bearing unit of described rotating shaft and shaft room outwards sets gradually from the lining and is radial thrust bearing, needle bearing and radial bearing.

Be provided with the outlet valve of venting at the shoe cream room place of shell.

Catch is housed in shell, and the borehole jack of catch is contained on the plunger, and the spring support on the plunger is on catch.

Be provided with the locating stud in the end slot that is flush-mounted in gland in the shell.

Advantage of the present utility model: the positive and negative both direction rotation of hand pump all can be worked.Radial thrust bearing, needle bearing and radial bearing are housed in the rotating shaft, rotate flexible, light.The plunger end roof pressure of hand pump is on the ring plate of radial thrust bearing, and both can relatively rotate, and surface friction drag is little.Plunger bushing is spacing by fixing catch in the enclosure, unloads lower stop piece and can change plunger, and is easy to maintenance.

Embodiment

Further specify the utility model below in conjunction with drawings and Examples.

A kind of hand pump comprises shell 2, plunger 18, oil sucting valve 22 and draining valve 21; The inner end of rotating shaft is provided with swash plate, and miniature radial thrust bearing 16 is installed on the swash plate through screw 17, and crank 11 is equipped with in the outer end of rotating shaft 9; 8 on rotating shaft 9 and axle sleeve are equipped with bearing unit, and axle sleeve 8 is contained in the hole of shell 2 right-hand members; The bearing unit that described rotating shaft 9 and axle sleeve are 8 outwards sets gradually from the lining and is radial thrust bearing 15, needle bearing 14 and radial bearing 13.The left end of shell 2 is provided with shoe cream room, and axial bore one end that is communicated with shoe cream room is put into fuel tap 22, the other end dress plunger bushing 20, and dress plunger 18 is equipped with Returnning spring 19 in the plunger bushing 20 on the plunger 18; Draining valve 21 is arranged on the Vertical direction in aforementioned axial hole; The end roof pressure of plunger 18 is on the ring plate of miniature radial thrust bearing 16.Be provided with the outlet valve 3 of venting at the shoe cream room place of shell 2.2 li catch 5 is housed at shell, the borehole jack of catch 5 is contained on the plunger 18, and Returnning spring 19 supports on the plunger 18 are on catch 5; Catch 5 is fixed on 2 li on shell through screw 4.2 li locating studs 6 that are provided with in the end slot that is flush-mounted in gland 7 of shell.The screw 12 that is contained in rotating shaft 9 ends is used for limiting the position of sleeve and axle bumper 10.After the shoe cream room oiling of shell 2, load onto pouring orifice and stop up 1, form the shoe cream room of a sealing.During use, at first oiling and load onto pouring orifice and stop up 1; Rotation crank 11 also drives rotating

shaft

9,16 rotations of miniature radial thrust bearing by the sleeve that links together with it, moves reciprocatingly thereby promote plunger 18; So just constantly from draining valve 21 pressure oil output.
