The fixing device comprises a barrel body and a filter element arranged in the barrel body. The fixing device is used for fixing the upper part of the filter element and is arranged on the filter element; a fixing nut, a gasket and a lower nut are sequentially connected with the fixing device; a neck is formed in the center of the fixing nut; and the filter element is contained in the neck. The fixing device capable of preventing the filter element from falling is simple in structure, low in cost, easy to operate, and convenient to implement.
Description
Technical field
The utility model relates to filter plant, relates in particular to a kind of fixture that can prevent that filter core from dropping.
Background technology
At present, the effect of filter in refining hydraulic oil, lubricated wet goods industrial production is more and more important, and filter core is the critical piece of filter.In production practices, when equipment filter element replacing, maintenance, the filter core import is because the Fluid Flow in A impact, the end face that filter core often occurs filter damages, cause filter core frequently to shake, in the process of using, filter core and nut loosening often occur, the situation that causes filter core to drop.
The utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and a kind of fixture that can prevent that filter core from dropping is provided, and it is simple in structure, and cost is low, and it is convenient to change, and is convenient to implement.
The technical solution of the utility model is: a kind of fixture that can prevent that filter core from dropping, it comprises cylindrical shell and is installed in the interior filter core of cylindrical shell, it is characterized in that, the fixture of fixing described filter core upper end also is installed on the described filter core, described fixture is connected with hold-down nut, pad and lower nut in turn, the center of described hold-down nut is provided with draw-in groove, and described draw-in groove is accommodated described filter core.
Further, the upper end in described cylindrical shell cavity is equipped with fixed head, and through hole is offered in the center of described fixed head, and described through hole is accommodated described lower nut.
Further, described lower nut has two sections, and top is one cylindrical, and the bottom is a limiting section, and described limiting section and described fixed head lean.
Further, the radius of described limiting section is greater than the radius on the top of described lower nut.
Further, the equal diameters of the diameter of described limiting section and described pad.
Further, described draw-in groove has up and down groove, and the cross section of described upper groove is the triangle of isosceles, and the cross section of described lower groove is rectangle.
Further, the angle of the waist of described upper groove and horizontal plane is 30 °.
The beneficial effects of the utility model are: filter of the present utility model, overcome existing filter because Fluid Flow in A impacts, cause that filter core frequently shakes, nut loosening, then the defective that drops of filter core, install and fix nut in the filter core upper end, offer draw-in groove on the hold-down nut, draw-in groove is accommodated filter core, the limiting section on the attaching nut again is so that filter core can steadily be fixed on the fixed head.The utility model is simple in structure, cost is low, simple to operate, be convenient to implement.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of A among the utility model Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in Figure 1 and Figure 2, it comprises cylindrical shell 1 and is installed in filter core 2 in the cylindrical shell 1, the fixture of fixing described filter core 2 upper ends also is installed on the described filter core 2, described fixture is connected with hold-down nut 3, pad 4 and lower nut 5 in turn, the center of described hold-down nut 3 is provided with draw-in groove, described draw-in groove is accommodated described filter core 2, upper end in described cylindrical shell 1 cavity is equipped with fixed head 6, through hole is offered in the center of described fixed head 6, described through hole is accommodated described lower nut 5, so that filter core 2 can steadily be fixed on the fixed head 6.
Preferably, described lower nut 5 has two sections, top is one cylindrical, the bottom is a limiting section 7, described limiting section 7 leans with described fixed head 6, effectively solved the situation that filter core 2 drops, wherein the radius of limiting section 7 is greater than the radius on the top of lower nut 5, the equal diameters of the diameter of limiting section 7 and pad 4.
Preferably, draw-in groove has up and down groove, and the cross section of described upper groove is the triangle of isosceles, and the cross section of described lower groove is rectangle, and the waist of upper groove and the angle of horizontal plane are 30 °.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or retouching, all should be encompassed in the protection domain of the present utility model.
