一种限制放电针位置的离子消除棒针板

Abstract

本实用新型公开了一种限制放电针位置的离子消除棒针板，包括针板开设多个盲孔，所述针板的正面设置有多个凸块，所述凸块有一通孔，所述通孔与所述盲孔对接，所述盲孔、所述通孔的组合孔中安装放电针。本实用新型在针板上设置多个凸块，将放电针插在凸块中，本申请增设凸块能够加大接触面积，增强放电针的稳定性，本申请将针板平放，取代立式安装，将放电针垂直压入针板中，更加稳定。

Claims

1. An ion eliminator needle plate for limiting the position of a discharge needle, characterized by: The needle plate (1) includes a plurality of blind holes (11) and a plurality of protrusions (2) on the front side of the needle plate (1). Each protrusion (2) has a through hole (21) which is connected to the blind holes (11). A discharge needle (3) is installed in the combination hole of the blind holes (11) and the through hole (21).

2. The ion elimination rod needle plate of claim 1, wherein: The inner wall of the through hole (21) is provided with an inverted step surface (24), and the outer wall of the discharge needle (3) is provided with a positive step surface (33). The inverted step surface (24) and the positive step surface (33) contact each other to form a limit to prevent the discharge needle (3) from detaching.

3. The ion elimination rod needle plate of claim 2, wherein: The entrance of the through hole (21) is a flared opening (22), and the inner diameter of the tip (23) of the flared opening (22) is smaller than the inner diameter of the through hole (21) to form the positive step surface (33).

4. The ion elimination bar needle plate of claim 2, wherein: The outer wall of the discharge needle (3) is integrally formed with a limiting ring (31), and the upper surface of the limiting ring (31) is the positive step surface (33).

5. The ion eliminator needle plate of claim 4 wherein: The limiting ring (31) has an inverted frustum structure and a guide slope (32) on its side.

6. The ion elimination rod needle plate of claim 1, wherein: The protrusion (2) is fixedly connected to the needle plate (1).

7. The ion elimination rod needle plate of claim 1, wherein: The outer end of the protrusion (2) is a rounded corner (25).
