Abstract

The two layers of filter paper clamping that needs combine is formed filter core by a kind of filter core salient point riveted clamp bar, including filter paper and clamp bar, the clamp bar together, and salient point is provided with the clamp bar sandwich serface.Clamp bar is metal material, the salient point formed by clamp bar relevant position described in punching press on the clamp bar sandwich serface.The utility model relies on salient point riveted principle, salient point clamping mode is added at clamp bar, together with salient point with filter paper can carry out impermeable riveting during the clamping, another aspect salient point also enhances the intensity of clamp bar itself, in the case where being under pressure, junction is just not easy to disengage, and ensures for the reliability of product.

Description

A kind of filter core salient point riveted clamp bar

Technical field:

Mechanical field, more particularly to the process technology of cleaner are the utility model is related to, especially a kind of filter core salient point riveted Clamp bar.

Background technology

Filter core is the main parts size in cleaner, and it is key technology to combine filter paper clamp bar when making filter core, with reference to Product bad must can be caused interior leakage, filtration inefficiencies occur.In the prior art, two layers directly needs combined with the clamp bar of irony Filter holder is combined, and the intensity of this combination ensures bond strength mainly by the intensity of irony clamp bar, in filter core work During have oil flowing pressure is produced to it, junction is occurred disengaging and is caused product filtration inefficiencies.

Utility model content

The purpose of this utility model is to be directed to drawbacks described above of the prior art, there is provided a kind of simple in construction, enhancing folder Close the salient point riveted clamp bar of intensity.

Its main operational principle is the salient point by being arranged on clamp bar sandwich serface, salient point and filter paper during clamping Impermeable riveting can be carried out together, so as to add clamping intensity.

To achieve the above object, the utility model uses following technical scheme：Including including filter paper and clamp bar, the clamp bar The two layers of filter paper clamping that needs combine is formed filter core together, it is characterised in that be provided with the clamp bar sandwich serface convex Point.

Further, the clamp bar is metal material, and the clamp bar clamping is formed by clamp bar relevant position described in punching press Salient point on face.

The utility model compares with prior art, and its effect is positive and obvious.The utility model relies on salient point riveting Principle is closed, salient point clamping mode is added at clamp bar, salient point can carry out impermeable riveting with filter paper during clamping Together, another aspect salient point also enhances the intensity of clamp bar itself, and in the case where being under pressure, junction is just not easy Disengage, ensure for the reliability of product.

Brief description of the drawings：

Fig. 1 is structure chart of the present utility model.

Fig. 2 is clamp bar front view of the present utility model

Embodiment：

Embodiment:

As shown in Figures 1 and 2, a kind of filter core salient point riveted clamp bar, including filter paper 2 and clamp bar 3, the clamp bar 3 is needs With reference to the clamping of two layers of filter paper 2 form filter core 1 together, it is characterised in that be provided with salient point 4 on the sandwich serface of clamp bar 3.

Further, as shown in Fig. 2 the clamp bar 3 is metal material, institute is formed by clamp bar relevant position described in punching press State the salient point 4 on clamp bar sandwich serface.Metal material passes through Sheet Metal Forming Technology, easily efficiently can form salient point on surface, together When further improves clamp bar rigidity, greatly strengthen the firmness of clamp bar and filter paper riveting.

Claims

1. a kind of filter core salient point riveted clamp bar, including filter paper and clamp bar, the clamp bar exist the two layers of filter paper clamping that needs combine Filter core is formed together, it is characterised in that is provided with salient point on the sandwich serface of the clamp bar.

2. filter core salient point riveted clamp bar as claimed in claim 1, it is characterised in that the clamp bar is metal material, passes through punching press The salient point that the clamp bar relevant position is formed on the clamp bar sandwich serface.
