Power pump.
The open and close type is connected as hinge connection, and hinge connection is provided with sealing strip.
The through hole is provided with rubber seal.
Also include warning device, warning device is connected with Nitrogen Detector.
The sealed compartment upper body and sealed compartment lower body closure junction are provided with sealed compartment sealing strip.
The connecting tube of the compression pump is located at sealed compartment upper body top middle portion.
Realization principle of the present utility model：Filled with helium inside filament lamp cell-shell, easy gas leakage at lamp holder in process of production,
Bulb is placed in closed container, gas probe is placed at lamp holder, when there is gas to spill, Nitrogen Detector can be reported automatically
It is alert.Because bulb is filled with gas, under "on" position, internal air temperature increases, and pressure becomes big, when lamp holder is in vacuum shape
State and when cell-shell is in pressurized state, can accelerate gas to leak, be easy to quickly detect.
The utility model is had the following advantages and effect relative to prior art：
1st, the utility model includes sealed compartment upper body and sealed compartment lower body, is opened and closed between sealed compartment upper body and sealed compartment lower body
Formula connects, and the bottom of sealed compartment lower body is provided with a dividing plate, is provided among dividing plate and is suitable to the through hole that bulb is placed, dividing plate and sealed compartment
Detection cabin is formed between lower body, detection cabin sets gas probe, and gas probe is connected with Nitrogen Detector, detects cabin and vavuum pump
Connection, sealed compartment upper body connection compression pump,
There is simple in construction, low cost, easy to detect, detection speed is fast and qualification rate is high.
2nd, the open and close type in the utility model is connected as hinge connection, and hinge connection is provided with sealing strip, easy to operation and inspection
Survey.
3rd, the through hole in the utility model is provided with rubber seal, can allow and detect the more preferable vacuum in cabin, the degree of accuracy is high, makes
With conveniently.
4th, warning device is also included in the utility model, warning device is connected with Nitrogen Detector, can be realized automatic
Alarm.
5th, the connecting tube of the compression pump in the utility model is located at sealed compartment upper body top middle portion, and pressure is uniform, uses effect
Fruit is good.
