2) the tightness degree of the thread of the electrode needle base with the existing thread structure is not easy to control in the assembling process, and the problems of thread slippage, fracture and the like caused by over-tightening rotation are easy to occur;

3) the tightness degree of the thread of the electrode needle base with the existing thread structure is not easy to control in the assembling process, and the electrode needle base is easy to rotate out of place to cause the problems of looseness, falling off and the like.

How to solve the connection and the fixed entrust between the mounting hole on electrode needle file and the charge eliminator main part, reduce the processing degree of difficulty, reduction in production cost guarantees assembly quality, avoids causing smooth tooth, fracture scheduling problem because of rotatory tension, fundamentally guarantees the whole assembly quality and the work life-span of charge eliminator device, is the actual technical problem that needs the solution in the actual work.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

In fig. 3, 4 and 5, a rotary buckle type structure is adopted between the electrode needle holder and the mounting hole on the static eliminator body (or the fixing piece of the electrode needle holder) in the technical scheme.

Specifically, at least 2L-shaped buckles 1-1 are arranged on the periphery of the lower part of the electrode needle holder 1.

Preferably, the L-shaped buckles are 4.

The 4L-shaped buckles are annularly arranged by taking the central axis of the electrode needle seat as the center and forming an angle of 90 degrees with each other.

Correspondingly, a fixing clamping rib 2-1 is correspondingly arranged at the mounting hole 2a of the static eliminator body 2 (or the electrode needle seat fixing piece); the number of the fixing clamping ribs is equal to the number of the L-shaped buckles on the electrode needle seat correspondingly.

The position of the fixing clamping rib at the mounting hole is arranged corresponding to the position of the L-shaped buckle on the electrode needle seat.

Obviously, the length of the transverse latch of the L-shaped buckle is equal to or less than the length of the corresponding fixed clamping rib, or the central angle corresponding to the transverse latch of the L-shaped buckle is equal to or less than the central angle corresponding to the corresponding fixed clamping rib.

Of course, the length or the corresponding central angle is not limited as long as the L-shaped buckle and the fixing clamping rib can be stably and reliably assembled together.

Because the L-shaped buckle and the fixed clamping rib can be produced by adopting a hot-press molding or hot-injection molding process, the production speed is high, and the product molding precision is high, the processing cost of related product parts can be greatly reduced; meanwhile, the electrode needle seat and the mounting hole are in a rotary buckle type structure, the electrode needle seat can be stably and reliably fixed in the mounting hole only by rotating by a rotation angle not larger than 180 degrees (only 90 degrees are required to rotate when four buckles are adopted), the technical requirements for assembly work and physical consumption of assembly personnel are reduced, the problems of screwing tightness, tooth sliding and the like caused by a thread structure can be avoided, the quality of product assembly is easier to control, and the stability, reliability and consistency of products are ensured.

The utility model discloses can extensively be used for the design and the manufacturing field of electrostatic elimination device.
