Description

Technical Field

[0001] The utility model relates to a filter, in particular to a filter with an automatic lubricating sealing rubber ring. Background Art

[0002] The oil filter, also known as the oil filter, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The oil filter is fixedly connected to the oil pump by a sealing rubber ring, and the sealing rubber ring is fixed to the oil outlet of the oil pump through the friction resistance between the oil pump and the oil pump.

[0003] Under the existing technology, in order to avoid a gap between the sealing rubber ring and the oil pump outlet that may cause oil leakage, thereby ensuring the sealing between the sealing rubber ring and the oil pump outlet, it is usually necessary to apply waste oil on the sealing rubber ring before installing the filter to avoid oil leakage and ensure that the sealing rubber ring will not be damaged during the filter installation process.

[0004] However, the engine oil applied to the sealing rubber ring is generally waste oil flowing out of the oil filter port. The waste oil contains certain impurities, which will have a certain impact on the installation of the filter. At present, the sealing rubber ring is manually oiled by the staff. Although the sealing rubber ring can be oiled more carefully, the oiling efficiency is low, and the staff may forget to oil the sealing rubber ring before installation, which will cause oil leakage.

[0025] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] like Figures 1 to 5 As shown, the utility model discloses a filter with an automatic lubricating sealing rubber ring, including a shell 11, and a sealing ring 12 is arranged in the end face of the shell 11. In order to ensure that the sealing ring 12 is wetted with engine oil when the staff installs the filter with the automatic lubricating sealing rubber ring, the shell 11 is covered with an oil supply device 13.

[0028] The oil supply device 13 includes a ring plate 14 arranged outside the housing 11, an oil storage chamber 35 is arranged in the ring plate 14, and an oil outlet plate 15 extending to the upper side of the ring plate 14 is slidably connected to the oil storage chamber 35 up and down, and a plurality of oil injection holes 16 are arranged at equal angles on the inner curved surface of the oil outlet plate 15 with the axis position of the housing 11 as the center, and a flow channel 17 penetrating downward and connected to the oil injection hole 16 is arranged in the oil outlet plate 15, and the upper end of the oil outlet plate 15 extends to the upper side of the housing 11, and when the filter of the automatic lubricating sealing rubber ring is pressed, the oil outlet plate 15 is provided with a plurality of oil injection holes 16, and ... When the filter is installed, the oil outlet plate 15 will abut against the mounting platform in the vehicle before the sealing ring 12, and then the oil outlet plate 15 will move downward relative to the ring plate 14. During this process, the engine oil in the oil storage chamber 35 will pass through the flow channel 17 and the oil injection hole 16 and then be sprayed inward onto the sealing ring 12, and the sealing ring 12 is moistened, thereby preventing the sealing ring 12 from being excessively worn during the installation of the filter with an automatic lubricating sealing rubber ring, and preventing oil leakage after the installation of the filter with an automatic lubricating sealing rubber ring is completed.

[0029] In the second embodiment of the filter of the automatic lubricating sealing rubber ring, in order to facilitate the reuse of the oil supply device 13, an oil filling hole 18 is provided on the curved surface of the oil storage chamber 35, and a one-way valve is provided in the oil filling hole 18. In order to facilitate the refilling of oil into the oil storage chamber 35, a curved oil nozzle 24 connected to the oil filling hole 18 is provided on the outer curved surface of the ring plate 14, and a pull plate 25 is provided on the outer curved surface of the oil outlet plate 15. With such a configuration, the staff can connect the curved oil nozzle 24 to the container for storing engine oil, and pull the oil outlet plate 15 upward relative to the ring plate 14 through the pull plate 25. In this process, the engine oil in the container can be replenished into the oil storage chamber 35 through the curved oil nozzle 24 and the oil filling hole 18 under the action of negative pressure adsorption.

[0030] In addition, the connection between the ring plate 14 and the shell 11 is a detachable connection, specifically: it also includes a support ring 19, a deformation gap 20 is opened in the support ring 19, and a fixing plate 21 is respectively provided on both sides of the deformation gap 20 of the support ring 19, a bolt 22 is rotatably connected to one of the fixing plates 21, and the bolt 22 is threadedly connected to the other fixing plate 21, the support ring 19 abuts against the lower side surface of the ring plate 14, and a part of the support ring 19 is fixed to the lower side surface of the ring plate 14. When it is necessary to separate the ring plate 14 from the shell 11, the staff can loosen the bolt 22 and make the deformation gap 20 larger. At this time, the friction between the support ring 19 and the shell 11 is not enough to fix the ring plate 14 and the shell 11 to each other, that is, at this time, the ring plate 14 can be separated from the shell 11, so as to facilitate the reuse of the oil supply device 13.

[0031] In addition, an oil scraper plate 23 is fixedly provided on the lower side of the oil outlet plate 15, and the inner and outer curved surfaces of the oil scraper plate 23 are respectively attached to the inner and outer curved surfaces of the oil storage cavity 35. A sealing ring is respectively provided inside the inner and outer curved surfaces of the oil scraper plate 23, so that the oil in the oil storage cavity 35 can be completely squeezed out when the oil outlet plate 15 moves downward.

[0032] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
