Abstract
The utility model discloses a center pipe of a filter cartridge. The center pipe is formed by spirally winding a steel belt. The steel belt comprises a steel belt body, wherein a first positioning part and a second positioning part are respectively arranged at two sides of the steel belt body along the length direction of the steel belt body and are matched with each other; a plurality of oil through holes are uniformly formed in the steel belt body and are positioned between the first positioning part and the second positioning part. The center pipe is formed by spirally winding the steel belt by one step, so that the center pipe is convenient to machine; the first positioning part is matched with the second positioning part, so that the center pipe is stably connected. Based on the structure, the center pipe is high in strength. In addition, the center pipe can be cut in a measuring manner by an operator according to the using length.
Description
Technical field
The utility model relates to a kind of filter core central tube.
Background technology
In prior art, filter core central tube in cleaner, after its processing is normally offered oil through on steel band, by operating personnel's amount of carrying out length, blocked, then circle is set as tubular, finally that the joint bonding is fixing, adopt said structure, operating personnel's inconvenient operation not only, and in the filter core of making, spool intensity is poor, then affects 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 filter core central tube is provided, and by ribbon spiral, is reeled and is formed, and intensity is higher, good product quality.
For achieving the above object, the technical solution of the utility model has been to provide a kind of filter core central tube, reel and form 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, evenly offer a plurality of oil throughs on described steel band body, a plurality of described oil throughs are between described the first location division and described the second location division.
As preferably, described oil through is punching.Oil through can also be the pressure hole with flange in addition, but compares punching, presses the flange in hole easily by hole plug, causes stifled oily phenomenon, and the waste material after punching can be recycled, and presses the flange in hole directly to be retained in the pressure bore edges, the waste resource.
As preferably, described the first location division is projection, and described the second location division is groove.The first location division and the second location division can be the hook-type flange in addition, and both match, and increase connective stability.
Advantage of the present utility model and beneficial effect are: the filter core central tube is reeled and is formed by ribbon spiral, one-shot forming, easy to process, by coordinating of the first location division and the second location division, make filter core central tube stable connection, adopt said structure intensity high, the operating personnel can be according to using the length amount of carrying out length to block in addition.
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 filter core central tube, reel and form 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, evenly offer a plurality of oil throughs 4 on described steel band body 1, a plurality of described oil throughs 4 are between described the first location division 2 and described the second location division 3, and described oil through 4 is punching.Adopt the form of punching, not only process more conveniently, and the left leftover pieces of punching can be recycled, and save production cost, adopt the punching form can guarantee not block up oil, then guarantee product quality.
As shown in Figure 2, described the first location division 2 is projection, and described the second location division 3 is groove.By projection and the coordinating of groove, the stable connection degree after the enhancing screw winding, the first location division 2 and the second location division 3, normally by the pressing equipment punch forming, process more convenient.
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.
