Abstract
The utility model discloses an anti-blocking filter element central pipe. The anti-blocking filter element central pipe comprises a central pipe body, and a plurality of oil penetration holes arranged on the central pipe body, wherein the oil penetration holes are punched holes. The oil penetration holes on the filter element central pipe are changed into the punched holes from the original pressure holes with turned edges, thus, the oil penetration oils are not easily blocked, and oil blockage phenomenon is avoided; moreover, the scrap material formed after punching can be recycled, and the cost is saved, while the turned edges of the pressure holes are directly left on the rims of the pressure holes.
Description
Technical field
The utility model relates to a kind of block-resistant type filter core central tube.
Background technology
In prior art, filter core central tube in cleaner, comprise the central tube body, be opened in a plurality of oil throughs on described central tube body, oil through generally adopts the form of pressing hole at present, and the so-called hole of pressing, be with flange steel band is pressed and worn, left over flange owing to pressing the hole periphery, easily cause the obstruction of oil through, then cause stifled oily phenomenon, affect product quality.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of block-resistant type filter core central tube is provided, and oil through is punching, is difficult for stifled oil, good product quality.
For achieving the above object, the technical solution of the utility model has been to provide a kind of block-resistant type filter core central tube, comprises the central tube body, is opened in a plurality of oil throughs on described central tube body, and described oil through is punching.
As preferably, described central tube body is reeled and is formed by ribbon spiral, described steel band comprises the steel band body, the both sides of described steel band body are respectively arranged with the first location division and the second location division along its length, match with described the second location division in described the first location division, a plurality of described oil throughs are between described the first location division and described the second location division.The intensity that strengthens the filter core central tube that coordinates by screw winding and the first location division with the second location division, improve the quality of product, and easy to process, reduces operating personnel's labour intensity, enhances productivity.
As preferably, described the first location division is projection, and described the second location division is groove, and the first location division and the second location division can be the hook-type flange in addition, and both match, the increase connective stability.
Advantage of the present utility model and beneficial effect are: on the filter core central tube, oil through changes punching into by original hole of the pressure with flange, make oil through be difficult for stopping up, can not cause stifled oily phenomenon, and the waste material after punching can be recycled, cost-saving, press the flange in hole directly to be retained in the pressure bore edges.
The accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is that the utility model launches schematic diagram.
In figure: 1, steel band body; 2, the first location division; 3, the second location division; 4, oil through.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, a kind of block-resistant type filter core central tube, comprise the central tube body, be opened in a plurality of oil throughs 4 on described central tube body, and described oil through 4 is punching.
As shown in Figure 1 and Figure 2, described central tube body is reeled and is formed by ribbon spiral, described steel band comprises steel band body 1, the both sides of described steel band body 1 are respectively arranged with the first location division 2 and the second location division 3 along its length, match with described the second location division 3 in described the first location division 2, a plurality of described oil throughs 4 are between described the first location division 2 and described the second location division 3.
As shown in Figure 2, described the first location division 2 is projection, and described the second location division 3 is groove.
In the present embodiment, steel band is by punching, and the screw winding moulding is then measured and longly blocked into required length through the operating personnel, processes more conveniently, and the intensity of product is high, and quality is good.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
