When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 8, the application discloses an oil cup not prone to dripping, which includes a cup body 1 for containing a lubricating medium and a felt 2 for providing the lubricating medium to an upright guide rail through capillary action, a lubricating area 11 for the guide rail to penetrate through is arranged on one side of the cup body 1, a bayonet 12 for installing the felt 2 is arranged in the lubricating area 11 of the cup body 1, an oil return structure 3 is arranged below the bayonet 12, and the oil return structure 3 includes;

the oil guide member 31, the oil guide member 31 has inclined bottom surface, the high side of the bottom surface extends to be close to the felt 2 as the oil inlet side, and the low side of the bottom surface is the oil outlet side;

the oil return opening 32 is formed in the side wall of the cup body 1, and is provided with a top edge and a bottom edge which are oppositely arranged, and the top edge of the oil return opening 32 is adjacent to the oil outlet side;

and an oil feeding plate 33, wherein the oil feeding plate 33 is arranged at the bottom edge of the oil return opening 32 and extends towards one side of the guide rail in an inclined and upward manner and is used for guiding the lubricating medium from the oil guide piece 31 into the oil return opening 32.

In the technical scheme disclosed in the application, the lubricating medium dripped by the felt 2 or the bayonet 12 is guided to the oil return port 32 through the oil guide piece 31, so that the lubricating medium is recovered. The lubricating medium in the oil cup is prevented from dripping on the well or the lift car in the related technology, the maintenance efficiency can be improved, and the maintenance frequency can be reduced.

The oil return opening 32 may be arranged in various ways, for example, in such a way that it opens towards the oil guide 31 to increase the guiding effect of the lubricating medium. In the embodiment shown in the attached drawings, the oil return opening is formed in the side wall of the cup body 1, and the design facilitates processing and production of the cup body 1 and control of cost. The function of preventing the lubricating medium from overflowing the oil return opening 32 is realized by the oil feed plate 33. The oil feed plate 33 is arranged obliquely upwards and can be formed by extending the material of the cup body 1. The oil feeding plate 33 and the oil return opening 32 form a small accommodating area, and when a large amount of lubricating medium exists, the lubricating medium can be temporarily accommodated in the accommodating area and is not easy to leave the cup body 1, so that dripping is further reduced.

In assembly, the bayonet 12 is formed by the cup body 1, and the other part is used for fixing the felt 2 by installing the pressing plate 13 so as to adjust the length of the felt 2 extending into the lubricating area 11.

The lubricating medium collected by the oil return opening 32 finally needs to enter the cup body 1, and when the lubricating medium in the cup body 1 is more, the liquid level of the lubricating medium is probably closer to the oil return opening 32. During operation of the car, the lubricating medium may escape from the oil return opening 32, which is undesirable for maintenance personnel. Therefore, in an embodiment, a part of the side wall of cup body 1 is obliquely arranged, and the side of the part of the side wall facing the inside of cup body 1 is used as a guide slope surface 15, the high side of guide slope surface 15 is positioned right below oil return opening 32, and the low side of guide slope surface 15 extends towards the inside of cup body 1.

The guide slope surface 15 can form a gravitational potential energy step, so that a lubricating medium of the oil return opening 32 can conveniently enter the cup body 1, the lubricating medium in the cup body 1 is prevented from reaching the oil return opening 32, and the possibility that the lubricating medium is dripped from the oil return opening 32 is greatly reduced.

During the operation of the car, vibrations may occur. The vibration may affect the lubricating medium on the oil guiding member 31, for example, the lubricating medium does not move along the gravity direction, so in an embodiment, the oil guiding member 31, the oil feeding plate 33 and the oil returning opening 32 form an oil returning path (not numbered) for the lubricating medium, and the oil returning structure 3 further includes oil blocking members 34 disposed on both sides of the oil returning path.

The oil baffle 34 can restrict the lubricating medium from entering the oil return port 32 along the oil guide 31. And the oil baffle 34 and the oil feeding plate 33 can form an accommodating area together, so that the dripping of the lubricating medium is reduced.

In terms of the dimensioning of the components, in one embodiment the width of the oil guide 31 is slightly greater than the width of the felt 2, and the width of the oil feed plate 33 is slightly greater than the width of the oil guide 31.

The oil guide 31, the oil return opening 32 and the oil feed plate 33 are arranged in this order on the path of travel of the lubricating medium. Therefore, the oil guide 31 having a width slightly larger than that of the felt 2 can effectively collect the lubricating medium dripped from the felt 2, and the oil feeding plate 33 having a width slightly larger than that of the oil guide 31 can effectively collect the lubricating medium dripped from the oil guide 31, thereby feeding the lubricating medium to the oil return port 32. The parts are mutually supported, and the redundant design on the width avoids the influence on the flow of the lubricating medium during the operation of the elevator car. "slightly greater" is reflected in the selection of specific values as "1% to 20% increase".

Similarly, in a particular component fit, the height of the oil return opening 32 is higher than the maximum specified level of the oil cup to ensure that oil does not directly spill out of the oil return opening 32. The height of the oil return opening 32 is higher than the height of the guide slope 15, so that the oil can slowly flow back into the oil cup under the influence of gravity after flowing back from the oil return opening 32 to the interior of the oil cup. The oil return opening 32 should have a certain width to prevent the lubricant from having too high surface tension and flowing into the oil cup under the influence of gravity.

The function of the oil cup is achieved by the mutual contact of the felt 2 and the rail, in one embodiment the oil feed plate 33 extends obliquely upwards towards the rail with a gap between them. The distance from the oil feed plate 33 to the protruding cup 1 is smaller than the distance from the felt 2 to the protruding cup 1, with the side of the cup 1 facing the guide rail as a base surface. This design can avoid guide rail and oil feeding plate 33 to interfere and cause unnecessary wearing and tearing and abnormal sound when improving oil feeding plate 33 to the recovery efficiency of lubricating medium.

In the selection of parameters, in one embodiment, the oil feeding plate 33 is at an angle of 35 to 60 degrees from the vertical.

The oil feeding plate 33 and the oil guide 31 have the same design in the angle with the vertical direction. Taking the oil feeding plate 33 as an example, the smaller the included angle between the oil feeding plate 33 and the vertical direction is, the better the flowing effect of the lubricating medium is, and the smaller the distance between the occupied space and the guide rail is, the longer the ramp can be formed, but the too small included angle causes the too large flow rate of the lubricating medium, so that the good entering of the oil return port 32 cannot be ensured. The oil feeding plate 33 and the vertical direction form an included angle of 35 degrees to 60 degrees, and the requirements of the oil feeding plate and the vertical direction can be met.

The oil return structure 3 can well solve the problem that the felt 2 drips the lubricating medium, and in the related art, the oil cup often lubricates a plurality of working surfaces of the guide rail. Therefore, in an embodiment, the cross section of the lubrication area 11 is C-shaped, three bayonets 12 are provided and are respectively arranged on two sides and a bottom edge of the C-shaped opening of the lubrication area 11, and the oil return structure 3 is provided below each bayonet 12.

Through the semi-surrounding of C font, can reduce the pollution of external environment to the lubricated medium, also can reduce the condition that the lubricated medium drips and spills the external environment.

In combination with the C-shaped design, the cup body 1 is designed with a half-height protrusion 14, in an embodiment, a part of the side wall of the cup body 1 is obliquely arranged, and one side of the part of the side wall facing the inside of the cup body 1 is used as a guide slope surface 15, the high side of the guide slope surface 15 is positioned right below the oil return opening 32, and the low side of the guide slope surface 15 extends towards the inside of the cup body 1;

guide slopes 15 are arranged on two sides of the C-shaped opening of the cup body 1 in the lubrication area 11, and the lubrication medium guided by each oil return structure 3 enters the cup body 1 through the corresponding guide slopes 15.

The guiding slope surface 15 on the protruding part 14 keeps a distance between the lubricating medium in the cup body 1 and the oil return structure 3, so that the lubricating medium is prevented from dripping through the oil return structure 3 while the oil return effect is ensured.

Except that the oil return structure 3, the felt 2 and the like are easy to drip, the cup body 1 moves along with the car and can shake in the process of the car moving. In an embodiment, the cup body 1 is further provided with a cup cover 16, the cup cover 16 is covered on the upward cup opening of the cup body 1 and hinged to one side, away from the guide rail, of the cup body 1, the cup body 1 is provided with a clamping groove 17, the cup cover 16 is provided with a clamping edge 161, and the clamping groove 17 and the clamping edge 161 are mutually matched to realize buckling of the cup cover 16 and the cup body 1. The cup cover 16 can reduce the pollution of the external environment to the lubricating medium and also can reduce the condition that the lubricating medium is dripped to the external environment. The condition of unexpected opening can be realized through buckling.

In some special cases, the lubricating medium in the cup body 1 can still leave the oil cup from the gap between the cup cover 16 and the cup body 1. In one embodiment, the inner side of the cap 16 is further provided with a spill prevention member (not shown) which is attached to the upper edge of the inner wall of the cup body 1. The splash guard shields the gap between the lid 16 and the cup 1 from the inside, further reducing the possibility of dripping of the lubricating medium. In this embodiment, the discharge member is realized by a catching edge 161.

In the related art, the installation channel 18 needs to be opened during the process of installing the oil cup, but during the process of filling the lubricating medium into the oil cup in the maintenance process, the lubricating medium may drip from the installation channel 18 or the gap, and the lubricating medium is more likely to overflow from the gap of the installation channel 18 during the process of running the car, in an embodiment, the middle part of the cup body 1 is provided with the installation channel 18, and the top surface of the installation channel 18 is provided with a sealing member 181 for separating the inside of the cup body 1 and the installation channel 18.

The technical scheme that this embodiment is disclosed has not only solved felt 2 and has dripped the problem of lubricated medium easily, has more improved cup 1 to can effectually solve among the related art oil cup and cause stained problem to car, well easily.
