[0004] The plastic framework oil filter element disclosed by the design has the following problems:

[0005] I. Single fixing mode and complex operation

[0006] The filter element is fixed by relying on a sealing assembly (such as a buckle or a bolt), which needs to be locked or disassembled manually point by point, so the efficiency is low and the filter element is not fixed firmly due to part wear.

[0007] II. Lack of dynamic adjustment and elastic reset mechanism

[0008] The filter element and the framework are rigidly connected, which cannot adapt to the deformation demand in high pressure or vibration environment, and the filter material is easily displaced or leaked due to stress concentration. UTILITY MODEL CONTENTS

[0009] In order to overcome the prior art, the utility model provides a kind of rib formula pull tube plastic filter core framework to solve the problems of single fixing mode and complex operation, and lack of dynamic adjustment and elastic reset mechanism.

[0010] In order to achieve the above object, the utility model provides the following technical scheme: a kind of rib formula pull tube plastic filter core framework, including positioning assembly, the positioning assembly includes support seat for supporting, the inside of the support seat is annularly provided with elastically slidable insertion rod, the side edge of the top of the support seat is provided with ring groove, the support seat is inserted and installed in ring groove and is used for filtering filter core assembly, the bottom of the support seat is provided with the screwing component that can be screwed into and then contact and push each insertion rod and complete the limiting and fixing of filter core assembly.

[0013] Preferably, the screwing component includes a worm, which is rotatably connected to the inside of the support seat, and further includes a handle, which is fixedly connected to the worm and located on the outside of the support seat.

[0014] Preferably, the screwing component further includes a shaft and a sealed bearing, the inner ring of the sealed bearing is fixedly connected to the shaft, and the outer ring of the sealed bearing is fixedly connected to the support seat.

[0015] Preferably, the screwing component further includes a worm wheel, which is fixedly connected to the bottom of the outside of the shaft, the worm wheel is in contact with the worm and is in meshing rotatable connection, the screwing component further includes a concave-convex plate, which is fixedly connected to the top of the sealed bearing, and the side edge of the concave-convex plate corresponds to the position of each insertion rod.

[0016] Preferably, the filter core assembly includes a filter core framework and a sleeve, the sleeve is fixedly connected to the bottom of the filter core framework, the size of the sleeve matches the ring groove, the sleeve is annularly provided with an insertion slot, and each insertion slot corresponds to the horizontal position of each insertion rod.

[0017] Preferably, the filter core assembly further includes a sealing ring, which is sleeved on the outside of the upper part of the sleeve.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] I. Mechanical linkage design for quick locking and dismounting

[0020] Improvement: The worm gear drives the worm and the worm gear engages with the concave-convex edge plate to convert rotary motion into linear displacement. The single-point operation of the knob can drive the ring-distributed insertion rod to advance or retreat synchronously.

[0021] Advantage: The closed assembly of the comparative document requires multiple-point operation, while the design achieves "one-key" locking through mechanical linkage, significantly improving installation efficiency and reducing the risk of component wear.

[0022] II. Elastic reset and adaptive adjustment mechanism

[0023] Improvement: The insertion rod is elastically connected to the sliding rod through a spring ring. After the "convex edge" of the concave-convex edge plate is separated, the insertion rod can automatically reset without manual intervention.

[0024] Advantage: The rigid connection of the comparative document can easily cause the filter core to deform under pressure, while the elastic mechanism of the design can adapt to slight deformation of the filter core, avoiding stress concentration and prolonging the service life of the filter core.

[0025] III. Integrated sealing and pre-positioning structure

[0026] Improvement: The side sleeve and ring groove are matched and inserted, combined with the pre-compression design of the sealing ring, to achieve preliminary sealing before the insertion rod is locked. The horizontal alignment of the insertion slot and the insertion rod ensures installation accuracy.

[0027] Advantage: The comparative document relies on late compression sealing, while the design improves sealing reliability through pre-positioning and double-sealing insertion slot + sealing ring, especially suitable for high-pressure or corrosive fluid environments.

[0028] IV. Rib structure enhances support adaptability

[0029] Improvement: The filter core skeleton adopts a ribbed tube drawing process, with a smooth surface and rib distribution consistent with fluid mechanics, reducing resistance. The annular rib design can closely fit the filter material to prevent displacement.

[0030] Advantage: The double-layer skeleton structure of the comparative document is complex and has poor adaptability, while the rib structure of the design balances strength and flexibility based on lightweight plastic materials, suitable for different filter material forms.

[0041] The screwing assembly 2 comprises a worm 211, which is rotationally connected inside the bearing seat 11, and a handle 21, which is fixedly connected with the worm 211 outside the bearing seat 11.

[0042] The screwing assembly 2 further comprises a rotating shaft 22 and a sealed bearing 23, the inner ring of the sealed bearing 23 is fixedly connected with the rotating shaft 22, and the outer ring of the sealed bearing 23 is fixedly connected with the bearing seat 11.

[0043] The screwing assembly 2 further comprises a worm wheel 221, which is fixedly connected at the bottom outside the rotating shaft 22, and the worm wheel 221 is in meshing rotational connection with the worm 211. The screwing assembly 2 further comprises a concave-convex plate 24, which is fixedly connected at the top of the sealed bearing 23, and the side edges of the concave-convex plate 24 correspond to the positions of the insertion rods 12.

[0044] The filter core assembly 3 comprises a filter core framework 31 and a side sleeve 32, which is fixedly connected at the bottom of the filter core framework 31, and the size of the side sleeve 32 matches the ring groove 111.
