Abstract
A spring supporting structure of a filter core in an automobile filter comprises a casing, the filter core and a screw thread cover plate, wherein the filter core is arranged in the casing; the screw thread cover plate is arranged in an opening in the upper end of the casing; an upper end of the filter core is adjacent to a lower side surface of the screw thread cover plate; a spiral compression spring is arranged between the upper end of the filter core and the bottom surface of the casing and is a reducing spring; and the spiral compression spring is dumbbell-shaped or tower-shaped; and a large-external-diameter end of the reducing spring is adjacent to the filter core. According to the spring supporting structure, the reducing spring is used for supporting the filter core in the automobile filter; the large-external-diameter end of the reducing spring is adjacent to the filter core, so that the stability of the filter core in the casing is increased; a small-internal-diameter part of the reducing spring increases the pressure of the spring, so that on the premise that the requirement for supporting force is met, the compression capacity is reduced, and the sealing requirement is met; and at the same time, when the reducing spring can reduce contact surfaces during stacking, the winding probability is reduced, separation is facilitated, and the speed of a product assembling line is increased.
Description
Technical field:
The utility model relates to automotive field, relates in particular to automobile filter, particularly the spring cupport structure of filter core in a kind of automobile filter.
Background technique:
Rotatable filter in automobile filter, its working principle enters shell for oil stream from thread plate, after filter core will have the oil of impurity to filter, enters motor, and wherein, filter core is connected with shell with thread plate by supported spring.Requirement to supported spring is: the support force of 1,90N ~ 120N; 2, there is stronger stability; The decrement of 3,8 ~ 12 height; 4, in production, be easy to separate.In prior art, the supported spring of filter cleaner all adopts cylindrical spring; Meet the demands 1 and require at 2 o'clock, its compression height has exceeded the scope of requirement 3, and in addition, cylindrical spring is easy to mutual winding aborning, is difficult to separate, and affects assembling speed.
Summary of the invention:
The purpose of this utility model is to provide the spring cupport structure of filter core in a kind of automobile filter, and in described this automobile filter, the spring cupport structure of filter core will solve in prior art in automobile filter that the supported spring compression height is too high, be easy to the technical problem be wound around mutually in assembly process.
The spring cupport structure of filter core in this automobile filter of the present utility model, comprise shell, filter core and thread plate, described filter core is arranged in described shell, described thread plate is arranged in the upper end open of shell, wherein, the upper end of described filter core is adjacent with the downside of described thread plate, is provided with a spiral compression spring between the upper end of filter core and the bottom surface of shell, and described spiral compression spring is Spring capable of diameter varying.
Further, described spiral compression spring is the middle concave Compress Spring, and the external diameter at its two ends all is greater than the external diameter at its middle part.
Perhaps, described spiral compression spring is conical Compress Spring, and the external diameter of one end successively decreases to the other end vertically.
Further, the large external diameter end of Spring capable of diameter varying is adjacent with filter core.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model adopts Spring capable of diameter varying to support filter core in automobile filter, the large external diameter end of Spring capable of diameter varying is adjacent with filter core, increased the stability of filter core in shell, the little inside diameter of Spring capable of diameter varying has increased the pressure of spring, thereby meeting under the prerequisite of support force, reduce decrement, meet the sealing requirement; Simultaneously, Spring capable of diameter varying can reduce surface of contact when piling up, and reduces and is wound around probability, is convenient to separate, and improves the Product Assembly linear velocity.
The accompanying drawing explanation:
Fig. 1 is the schematic diagram of the Spring capable of diameter varying in the spring cupport structure of filter core in automobile filter of the present utility model.
Fig. 2 is the schematic diagram of the spring cupport structure of filter core in automobile filter of the present utility model.
Embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, the spring cupport structure of filter core in automobile filter of the present utility model, comprise shell 1, filter core 2 and thread plate 3, described filter core 2 is arranged in described shell 1, described thread plate 3 is arranged in the upper end open of shell 1, and wherein, the downside of the upper end of described filter core 2 and described thread plate 3 is adjacent, be provided with a spiral compression spring 4 between the bottom surface of the upper end of filter core 2 and shell 1, described spiral compression spring 4 is Spring capable of diameter varying.
Further, described spiral compression spring 4 is middle concave Compress Springs, and the external diameter at its two ends all is greater than the external diameter at its middle part.
Perhaps, described spiral compression spring 4 is conical Compress Springs, and the external diameter of one end successively decreases to the other end vertically.
Further, the large external diameter end of Spring capable of diameter varying is adjacent with filter core 2.
The present embodiment adopts Spring capable of diameter varying to support filter core 2 in automobile filter, the large external diameter end of Spring capable of diameter varying is adjacent with filter core 2, increased the stability of filter core 2 in shell 1, the little inside diameter of Spring capable of diameter varying has increased the pressure of spring, thereby meeting under the prerequisite of support force, reduce decrement, meet the sealing requirement; Simultaneously, Spring capable of diameter varying can reduce surface of contact when piling up, and reduces and is wound around probability, is convenient to separate, and improves the Product Assembly linear velocity.
In Fig. 2, band arrow curve has meaned oily flow path.
