Abstract
The utility model provides a hand pump protection structure, which comprises a rocker shaft, a pump body, a bearing, an O-shaped ring and a dustproof end cover; the O-shaped ring is sleeved on the rocker shaft, the rocker shaft is arranged in the bearing, and the bearing is pressed into the pump body hole; and a dustproof end cover is arranged between the pump body and the rocker component. A hand pump protective structure, under the existing overall structure condition of unchanging, increase a loudspeaker form metal skeleton structure's dustproof end cover, prevent that granule dust and harmful liquid from passing through in rocking arm axle and the bearing clearance gets into the bearing to protection O shape circle increases the life of O shape circle, promotes hand pump reliability and life-span. The structure and the manufacturing process are simple, the installation is convenient, and the protection effect is good.
Description
Technical Field
The utility model relates to a driver's cabin hydraulic pressure upset system specifically relates to a hand pump protective structure.
Background
In a manual pump in a cab hydraulic turnover system, a sealing structure at a rocker shaft is mostly sealed by adopting an O-shaped ring, and an end cover without a protection function is adopted between the rocker shaft and a pump body for axial positioning. At present, the working environment of a commercial vehicle is severe, particle dust and harmful liquid in the working environment can enter the bearing and the O-shaped ring through a gap between the rocker shaft and the bearing, and when the rocker shaft and the O-shaped ring rotate, the abrasion and the aging of the O-shaped ring are accelerated, the sealing performance of the O-shaped ring is affected, and the manual pump has oil leakage fault or even fails. The manual pump leaks oil, needs the maintenance of stopping, needs specialized tool to dismantle the manual pump and open, assembles the manual pump again after changing O shape circle, and maintenance work volume is big, the dismouting cleanliness requires highly, influences production transportation.
Disclosure of Invention
The utility model aims at providing a hand pump protective structure can effectively keep apart granule dust and harmful liquid, improves the adaptability of hand pump to adverse circumstances, prolongs the life of hand pump.
In order to solve the technical problem, the technical scheme of the utility model as follows: a manual pump protection structure comprises a rocker shaft, a pump body, a bearing, an O-shaped ring and a dustproof end cover; the O-shaped ring is sleeved on the rocker shaft, the rocker shaft is arranged in the bearing, and the bearing is pressed into the pump body hole; and a dustproof end cover is arranged between the pump body and the rocker component. The utility model discloses a be equipped with dustproof end cover between the pump body and rocker arm subassembly, effectual prevention granule dust and harmful liquid get into the bearing hole through the gap between bearing and the rocking arm axle, have prolonged the life of O shape circle, have promoted the hand pump reliability.
The improvement of the technical scheme is as follows: the dustproof end cover is of a metal framework structure and is horn-shaped, the lower end bell mouth is made of rubber materials and tightly attached to the pump body, and the upper end of the dustproof end cover is tightly attached to a shaft shoulder of the rocker shaft and the bearing, so that the function of axial fixation is realized. The lip diameter of this structure's dustproof end cover, horn mouth department is greater than bearing excircle diameter, consequently wraps up pump body hole, bearing in the horn chamber, the lip interference is hugged closely in pump body surface, forms external seal, prevents that granule dust and harmful liquid from getting into in the bearing through rocking arm axle and bearing clearance.
Has the advantages that:
a hand pump protective structure, under the existing overall structure condition of unchanging, increase a loudspeaker form metal skeleton structure's dustproof end cover, prevent that granule dust and harmful liquid from passing through in rocking arm axle and the bearing clearance gets into the bearing to protection O shape circle increases the life of O shape circle, promotes hand pump reliability and life-span. The structure and the manufacturing process are simple, the installation is convenient, and the protection effect is good.
Drawings
FIG. 1 is a sectional view of a manual pump without a protective structure.
Fig. 2 is a sectional view of the protective structure of the hand pump of the present invention.
In the figure: 1-rocker shaft; 2-end cover; 3, a bearing; 4-O-shaped ring; 5, a pump body; 6, dust-proof end cover. A-lip.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a hand pump protective structure, as shown in figure 2, including rocking arm axle 1, bearing 3, O shape circle 4, the pump body 5, dustproof end cover 6. The O-shaped ring 4 is sleeved on the rocker shaft 1 and is arranged in the bearing 3 along with the rocker shaft 1, the bearing 3 is pressed into the hole of the pump body 5, the dustproof end cover 6 is arranged between the bearing 3 and the rocker shaft 1, and the lip A at the bell mouth of the dustproof end cover 6 is tightly attached to the pump body 1, so that particle dust and harmful liquid are effectively prevented from entering the bearing through the gap between the rocker shaft and the bearing, the O-shaped ring is protected, the service life of the O-shaped ring is prolonged, and the reliability and the service life of the manual pump are improved. The structure and the manufacturing process are simple, the installation is convenient, and the protection effect is good.
