Description

High stability filter

Technical Field

The utility model relates to a filtration equipment technical field, concretely relates to filter.

Background

The filter is an accessory which plays a role of filtering impurities or gas through filter paper, is mainly applied to the field of automobiles, and has the main function of filtering impurities in gasoline to ensure that the automobiles can be normally started. However, in the prior art, the filter element is arranged in the shell and supported by the spring for positioning, the automobile vibrates in the driving process, the filter element and the spring are easy to displace, the service life is shortened, and the filter is inconvenient to install in the automobile.

Disclosure of Invention

In view of the deficiencies in the prior art, the utility model aims at providing a reasonable in design, simple to operate, effective fixed filter core and spring to better guarantee life's filter.

The utility model adopts the following technical proposal to complete:

high stability filter, including casing, roof, thread cover board, filter core and spring, thread cover board's center is equipped with the oil-out, centers on the oil-out is equipped with a plurality of oil inlets, inside the casing was arranged in to the filter core, the bottom by the spring holds up its characterized in that: the circle is equipped with the internal thread in the pipe wall of oil-out, the spring is arranged in inside the casing is equipped with first holding ring respectively with casing lower extreme face contact position, the filter core includes center tube, filter media, upper end cover and lower extreme cover, the tip of upper end cover is equipped with holding ring and first holding ring on the second, the holding ring is gone up to the last third that is equipped with of lower extreme cover and second, the spring comprises little spring and the big spring of diameter difference, little spring with big spring structure as an organic whole, the lower extreme cover bottom is equipped with the confession the interior concave part that little spring packed into.

Above-mentioned technical scheme's the internal screw thread setting of circle in the filter oil-out pipe wall can effectively pass through threaded connection on other parts in the car with the filter, through the effect of holding ring effective fixed filter core and spring, and the design of big or small spring ensures that spring and filter element group spare are connected more stably, reliably in addition, the better effect of having played the spacing end of holding in the palm for the filter core can not produce vibrations and the displacement slides because of the in-process that the car went.

Preferably, the central tube is provided with an inner cylindrical tube and an outer cylindrical tube which are coaxially arranged inside and outside, the inner cylindrical tube is arranged in the center of the outer cylindrical tube, the length of the inner cylindrical tube is smaller than that of the outer cylindrical tube, a square hole is formed in the cylindrical surface of the outer cylindrical tube, the filter material is wrapped on the outer circle of the outer cylindrical tube, and an exhaust hole is formed in the lower end face of the inner cylindrical tube. The design can effectively avoid insufficient oil supply caused by the air resistance phenomenon.

Preferably, a positioning rubber pad is arranged in an inner hole of the second upper positioning ring and sleeved on the excircle of the pipe wall of the oil outlet, the hole diameter of the inner hole of the first lower positioning ring is matched with the diameter of the filter material, the lower end cover is matched with the diameter of the small spring, and the hole diameters of the inner holes of the first upper positioning ring and the second lower positioning ring are matched with the excircle diameter of the large spring. The design is sufficient to position the spring and the filter element.

Drawings

The utility model discloses there is following figure:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in the drawing, the utility model discloses a filter, which comprises a housin 1, roof 2, thread cover plate 3, filter core and spring 4, thread cover plate 3's center is equipped with oil-out 5, be equipped with a plurality of oil inlets 6 around oil-out 5, the filter core is arranged in inside the casing, the bottom is held up by spring 4, circle in oil-out 5's the pipe wall is equipped with internal thread 7, make oil-out 5 can directly pass through screw thread fixed connection in the automobile body, spring 4 arranges inside with casing lower extreme face contact position in the casing in and is equipped with first upper holding ring 8 respectively, the filter core includes the center tube, filter media 9, upper end cap 10 and lower end cap 11, the tip of upper end cap 10 is equipped with holding ring 12 and first holding ring 13 on the second, be equipped with holding. Effectively fixed filter core and spring through the effect of holding ring, the center tube has inside and outside coaxial setting in, outer cylinder pipe, interior cylinder pipe 16 is located outer cylinder pipe 17 central authorities and length is less than outer cylinder pipe 17, be equipped with quad slit 18 on outer cylinder pipe's the cylinder, filter media 9 parcel is on outer cylinder pipe 17's excircle, the terminal surface is equipped with exhaust hole 19 under interior cylinder pipe 16, spring 4 comprises the different little spring of diameter and big spring, little spring and big spring structure as an organic whole, lower extreme cover 11 bottom is equipped with the interior concave part that supplies little spring to pack into, it is more stable to ensure being connected of spring and filter element group spare, it is more reliable, better effect at the bottom of spacing support has been played, make the filter core can not slide because the in-process production vibrations that the car traveles.
