Detailed Description

In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 1, are merely for convenience in describing the present utility model, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

For the purposes and advantages of the present utility model to become more apparent, the following detailed description of the utility model will be taken in conjunction with the accompanying examples, with the understanding that the following text is intended to describe only one or several embodiments of the utility model and is not intended to limit the scope of the utility model to the exact geometric definition, as used herein, the terms up, down and left to right are not limited to the exact geometric definition thereof, but rather include tolerances for machining or human error, and the exact nature of the filter to facilitate disassembly and replacement is described in detail below:

referring to fig. 1-2, a filter with easy disassembly and replacement according to an embodiment of the present utility model includes a filter core bottom case 10, a bottom cover 11 is screwed on the upper end of the filter core bottom case 10, an outer fixing ring 16 is fixed on the upper end surface of the bottom cover 11, a hexagonal head 17 is disposed in the outer fixing ring 16, and the hexagonal head 17 is fixed on the upper end surface of the bottom cover 11.

An inner fixing ring 12 is arranged between the hexagon head 17 and the outer fixing ring 16, and the inner fixing ring 12 is fixed on the upper end face of the bottom cover 11.

Outer reinforcing ribs 13 circumferentially distributed by taking a hexagon head 17 as a center are fixed between the inner fixing ring 12 and the outer fixing ring 16, each outer reinforcing rib 13 is fixed on the upper end face of the bottom cover 11, and the outer reinforcing ribs 13 strengthen the connection strength between the inner fixing ring 12 and the outer fixing ring 16, so that the overall weight of the novel anti-theft device is also reduced.

The cross section of the hexagonal head 17 is regular hexagon, and the traditional hexagonal socket wrench can be sleeved on the hexagonal head 17, so that the bottom cover 11 can be disassembled and assembled.

Inner reinforcing ribs 15 distributed circumferentially are fixed between the hexagonal head 17 and the inner fixing ring 12, each inner reinforcing rib 15 is fixed on the upper end face of the bottom cover 11, and the inner reinforcing ribs 15 strengthen the strength between the hexagonal head 17 and the inner fixing ring 12 and lighten the integral strength of the utility model.

The hexagonal head 17 is internally provided with reinforcing ribs 14 distributed circumferentially, and the reinforcing ribs 14 can enhance the strength of the hexagonal head 17.

The specific use is as follows:
