Description

A kind of resistance to deformation filter element

Technical field

The utility model relates to Vehicular cleaner fields, and more specifically it is related to a kind of resistance to deformation filter element.

Background technique

It in automobile engine operation process, needs to be passed through air-breathing, and usually contains sand, dust and water in air The foreign matters such as vapour be easy to cause the abrasion of cylinder body after foreign matter enters the cylinder body of engine；If the volume of foreign matter is larger, can Engine throttle valve body can be blocked, valve body work is caused to have some setbacks；After foreign matter enters in engine motor oil, it may accelerate to send out The abrasion of motivation.Therefore, filter is commonly configured with before automobile engine to fall the foreign body filtering in air.

Authorization Notice No. is that the Chinese utility model patent of CN201925059U discloses a kind of automobile filter element, is wrapped It including by the longitudinal folding hollow cylindrical ontology constituted of filter paper material, ontology axial ends is respectively set there are two annular end face, There are two the end cap for being covered each by annular end face, the hollow inside of ontology to be provided with skeleton for ontology setting, and end cap and skeleton are in one Body setting, and be made of engineering plastics integral molded plastic.Body peripheral is surrounded with screw-tightened line.

The end cap and skeleton of above-mentioned filter element are integrally formed, and have saved material cost, so that processing is more convenient, and Filter paper is made to be not easy to close up by the way that screw-tightened line is arranged.But since fastening line is thinner, the contact between filter paper material is few, right It is slightly worse in the fastening effect of filter paper, it is also possible that the phenomenon that filter paper closes up after a period of use in filter.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of resistance to deformation filter element, Have the function of preferably preventing filter paper from closing up.

To achieve the above object, the utility model provides following technical solution:

A kind of resistance to deformation filter element, comprising: tube body and the core being converted by filter paper；The core passes through the pipe Body；One end of the tube body is provided with the end cap for the core end abutment；It further include that several are passed through for the core Lantern ring, the inner ring of the lantern ring are uniformly surrounded with multiple plectrums for protruding into filter paper crease in the core, the plectrum with Paper sews up the thickness between the two sides of touching and is gradually reduced along its end direction.

So set, crease can be strutted after plectrum is in the crease for going deep into core, avoid filter paper in use Close up；Gradually thinned plectrum can go deep into the maximum extent in gap and be not easy to scratch with the wall surface of filter paper, so that set Ring it is easier for installation laborsaving.

Further setting: the quantity of the lantern ring is no less than 3 and arranges at equal intervals.

So set, so that the crease arrangement on core is more uniform, being further increased by several lantern ring collective effects The filter effect of filter core.

Further setting: it is fixedly connected between the adjacent lantern ring by fixed strip.

So set, each lantern ring is enabled not occur to slide and affect using effect on core, device is improved Stability.

Further setting: being provided with fixing groove on the end face of the lantern ring, and the end insertion of the fixed strip is described solid Determine slot and is adhesively fixed.

So set, to be stably connected between lantern ring and fixing groove.

Further setting: have and the core end abutment in the tube body far from the other end releasable connection of the end cap Limited cover.

So set, limited cover plays positioning action to core and lantern ring, core is avoided to slide.

Further setting: it is provided on the limited cover and protrudes into the intracorporal fixed ring of the pipe, the periphery of the fixed ring Face is provided with external screw thread, and the inner wall of the tube body is provided with internal screw thread.

So set, fixing the mode that can be connected through a screw thread on limited cover with tube body, while easy to disassemble.

Further setting: multiple ventholes are provided on the tube body.

So set, venthole is filtered for introducing air into core.

In conclusion the utility model has the advantage that

1. the core being converted by filter paper will not close up under the action of lantern ring plectrum, so that the paper filter core kept is whole The stabilization of shape improves the filter effect of filter；

2. thimble structure is simple and reliable, install convenient.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of resistance to deformation filter element, as shown in Figure 1, including tube body 1 and core 2.Wherein, core 2 is by folded filter paper It forms, in tubular construction.Tube body 1 passes through among core 2, and venthole 12 is provided on tube body 1 for introducing air into core In body 2；The other end of tube body 1 is provided with the end cap 3 for 2 end abutment of core.Several are also arranged in the periphery of core 2 Lantern ring 4.

Specifically, in conjunction with Fig. 2 and Fig. 3, multiple plectrums 5 are uniformly surrounded in the inner ring of lantern ring 4, each plectrum 5 is right It protrudes into answering in each crease of core 2.And to protrude into convenient for plectrum 5, plectrum 5 and paper sew up the distance between two sides of touching It is gradually reduced along its end direction, forms triangular structure.

In conjunction with Fig. 2, the quantity of lantern ring 4 is no less than 3 and arranged at equal intervals, is provided with no less than between adjacent lantern ring 4 Three, with the fixed strip 6 for fixing the two, fixed strip 6 is uniformly distributed around the center of lantern ring 4.Specifically, lantern ring 4 can be equal with fixed strip 6 It selects plastics to be made, and is provided with fixing groove 7 on the end face of lantern ring 4, the end insertion fixing groove 7 of fixed strip 6 is simultaneously bonded solid It is fixed.

It is provided with further to play position-limiting action to core 2 and lantern ring 4 in the other end of tube body 1 in conjunction with Fig. 1 and Fig. 3 It is equally used for resisting the limited cover 8 of 2 end of core.Specifically, the fixed ring 9 protruded into tube body 1 is provided on limited cover 8, The outer peripheral surface of fixed ring 9 is provided with external screw thread 10, and the inner wall of tube body 1 is provided with internal screw thread 11.

A kind of installation process of resistance to deformation filter element: tube body 1 is passed through among core 2, make the end of core 2 with End cap 3 abuts.Each lantern ring 4 is adhesively fixed in advance by fixed strip 6, the lantern ring 4 fixed is set in core 2 later Periphery, and each plectrum 5 is entered in the crease of core 2.Limited cover 8 is finally tightened in the other end of tube body 1, make its with The end of core 2 resists, to complete the installation of resistance to deformation filter element.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model Within the scope of.
