SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems of poor sealing performance of a body shell and oil leakage caused by vibration of a pump body in the background art, and oil waste caused by oil leakage.

The technical scheme provided by the utility model is as follows:

a leak prevention mechanism for an oil pump, comprising: the annular oil collecting device comprises an annular liner, an outer shell and an oil collecting box matched with the outer shell;

the housing, comprising: two arc cell shells that the structure is the same completely, the both ends of arc cell shell are equipped with first extension cell shell and second extension cell shell respectively, two the both ends accessible bolt fastening of arc cell shell, be equipped with the draw-in groove on the diapire of arc cell shell, be equipped with the guiding gutter on the diapire of draw-in groove, annular inside lining can inlay the dress in the draw-in groove, be equipped with the spacing groove on the inner wall of second extension cell shell, the port both ends of collection oil box all are equipped with the cardboard, the cardboard can clamp the spacing inslot that corresponds the arc draw-in groove, the inside water conservancy diversion passageway that is equipped with of second extension cell shell, the one end and the guiding gutter of water conservancy diversion passageway communicate with each other, the other end port setting of water conservancy diversion passageway is in the spacing groove top.

Preferably, the annular lining is made of wood cellulose sponge.

Preferably, a fixing column is fixedly installed in the bottom plate of the oil collecting box.

Preferably, the outer edge of the port of the oil collecting box is provided with a slope surface structure.

The beneficial effects of the utility model are embodied in the following aspects:

1. according to the utility model, the outer shell and the inner liner are installed in a matched manner, the device is fastened on the side wall of the port of the oil pump through the bolt, the annular inner liner is made of wood cellulose sponge, when the oil leakage phenomenon occurs to the outer shell of the oil pump, the leaked oil can be adsorbed by the annular inner liner, when the inner liner is saturated or vibrates, the oil from the inner liner flows to the oil guide channel along the clamping groove and the oil guide groove due to the gravity effect, and finally flows into the oil collecting box for storage, so that the oil leakage in the oil pump can be avoided, and the oil waste is reduced.

Detailed Description

The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the utility model by referring to the description text.

As shown in fig. 1 to 5, the present invention provides a leakage preventing mechanism for an oil pump, including: the oil collecting device comprises an annular liner 1, a shell and an oil collecting box 3 matched with the shell;

the housing, comprising: two arc shells 2 that the structure is the same completely, the both ends of arc shell 2 are equipped with first extension shell 5 and second extension shell 6 respectively, and the second extension shell 6 sets up in the oil pump below with the second extension shell in the installation, and first extension shell 5 sets up in the oil pump top, is of value to and makes fluid receive the influence of gravity to flow to an album oil box 3, avoids extravagant. Two both ends accessible bolt fastening of arc cell shell 2, be equipped with draw-in groove 7 on the diapire of arc cell shell 2, be equipped with guiding gutter 8 on the diapire of draw-in groove 7, guiding gutter 8 sets up in draw-in groove 7, is of value to and prevents that the fluid that annular inside lining 1 came out from spurting to other positions, and guiding gutter 8 itself also is of value to the fluid and flows into water conservancy diversion passageway 11 smoothly and finally flows into collection oil box 3. Annular inside lining 1 can inlay the dress in draw-in groove 7, is of value to conveniently changing annular inside lining 1, be equipped with the spacing groove on the inner wall of second extension groove shell 6, the port both ends of collection oil box 3 all are equipped with cardboard 9, cardboard 9 can clamp the spacing inslot that corresponds arc draw-in groove 7, is of value to the stability of guaranteeing collection oil box 3, the inside water conservancy diversion passageway 11 that is equipped with of second extension groove shell 6, the one end and the guiding gutter 8 of water conservancy diversion passageway 11 communicate with each other, the other end port setting of water conservancy diversion passageway 11 is in the spacing groove top, and the port outer fringe of collection oil box 3 is equipped with domatic structure 10, and domatic structure 10 is of value to in fluid flows into collection oil box 3 smoothly.

The working principle of the utility model is as follows: according to the utility model, the outer shell and the inner liner are installed in a matching way, the device is fastened on the side wall of the oil pump port through bolts, the annular inner liner 1 is made of wood cellulose sponge, when the oil leakage phenomenon occurs to the oil pump outer shell, the annular inner liner 1 can absorb leaked oil, when the annular inner liner 1 is saturated or the annular inner liner 1 vibrates, the oil from the inner liner flows to the oil guide channel along the clamping groove 7 and the oil guide groove of the corresponding arc-shaped groove box due to the action of gravity and finally flows into the oil collecting box 3 for storage, and the function of the flow guide channel 11 arranged in the second extension groove shell 6 is beneficial to preventing the oil from flowing in the inner part and avoiding secondary leakage in the arc-shaped groove shell 2 when the oil output of the annular inner liner 1 is too large. The mechanism can effectively prevent the waste caused by the leakage of oil from the pump body, is beneficial to collecting and recycling the leaked oil and prevents the oil from flowing to other positions of the pump body. The fixing column 4 is fixedly arranged in the bottom plate of the oil collecting box 3, and the bottom fixing of the shell is facilitated by matching with a bolt.
