Abstract

The utility model discloses a plastic end cover for an oil filter. The plastic end cover comprises a cover body, wherein a group of concave-convex line structures are formed on the surface of the cover body. A group of concave-convex line structures are formed on the surface of the cover body, so that high-efficiency and high-yield production of the plastic end covers for the oil filters is realized; and due to the concavo-convex line structures, flying edges and burrs are not produced during adhering, and the plastic end cover can be firmly adhered with filter paper. The plastic end cover has a rational and simple structure and an attractive appearance and deserves to be widely popularized and used.

Description

The oil filter plastic end cover

Technical field

The utility model relates to a kind of cleaner, relates in particular to a kind of oil filter plastic end cover.

Background technology

Cleaner is a kind of purifier that filters machine oil or fuel oil acrobatics, is widely used in various automobile engine fuel oil, the oil filtration system.The core component of cleaner is a filter core, and the flow resistance of cleaner and service life is directly by the quality decision of filter core performance, and traditional filter core is made up of parts such as end cap, filtration paper cylinder, central tube up and down.And the filter element end cap hot plate type welding that has at present; The end cover surface structure that is adopted is smooth, and shortcoming is that surface melting is incomplete after the end cap melted by heat, is prone to produce overlap; Burr or with filter paper bonding insecure in addition sometimes filter paper with on end cap does not also contact; The end cover surface just plastics of fusing is solidified, and finally causes production efficient low, and scrappage is high.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of fusing effective, and is bonding firm, is prone to the oil filter plastic end cover of production and processing.

The utility model solves the technical scheme that its technical problem adopts: this oil filter plastic end cover, comprise lid, and top surface is provided with one group of concave convex texture structure.Like this, lid asperities line structure fusing ground after receiving high temperature is more complete, is easy to production and processing, has effectively shortened the production cycle, and bonding firm, effectively improves product percent of pass and good looking appearance degree.

Further, concave convex texture structural section structure triangular in shape.Be convenient to the lid thawing of heating like this.

The concave convex texture constructional depth is between 0.2 ㎜～0.6 ㎜, and the concave convex texture structure width is between 0.3 ㎜～0.7 ㎜.

Further, the concave convex texture constructional depth is 0.4 ㎜, and the concave convex texture structure width is 0.5 ㎜.At this moment the be heated effect of heat bonding of concave convex texture structure is best, helps improving production efficiency of products and qualification rate.

Lid is the Reinforced Nylon lid.The Reinforced Nylon lid has good impact resistance, hear resistance, lower temperature resistance, chemical proofing and anti-electric property, and this Reinforced Nylon lid still has high stability in the machine oil of 135 ° of high temperature, and result of use is good.

The effect that the utility model is useful is: the utility model is rational in infrastructure, simple; Through one group of concave convex texture structure is set in top surface, realize that oil filter plastic end cover high efficiency, high qualification rate ground produce, and through the use of concave convex texture structure non-trimming when bonding; No burr; And bonding between filter paper firmly product design is attractive in appearance, and use should be widely promoted.

Description of reference numerals: end cap 1, concave convex texture structure 2, triangular structure 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

With reference to accompanying drawing: this oil filter plastic end cover, comprise lid 1, lid 1 surface is provided with one group of concave convex texture structure 2.This concave convex texture structure 2 cross sections structure 3 triangular in shape.Concave convex texture structure 2 degree of depth are between 0.2 ㎜～0.6 ㎜, and concave convex texture structure 2 width are between 0.3 ㎜～0.7 ㎜.Lid 1 is the Reinforced Nylon lid.

When the utility model used, the welding of filter element end cap hot plate type was under the effect of concave convex texture structure 2; Lid 1 fusing ground is more complete, is easy to production and processing, has effectively shortened the production cycle; And bonding firm, effectively improve product percent of pass and good looking appearance degree.

Concave convex texture structure 2 preferred depth are 0.4 ㎜, and said concave convex texture structure 2 preferable width are 0.5 ㎜.

Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
