Abstract
The invention discloses a sucker type vacuum test mechanism, which comprises an air extraction hood, an air duct and a sucker device, wherein one end of the air duct is fixedly connected with a top end of the air extraction hood, while the other end is connected with an air extraction device; and the sucker device is fixed at a bottom end of the air extraction hood. The sucker device is sucked on a to-be-tested product, and the to-be-tested product is firmly fixed on the sucker device due to air pressure difference inside and outside the sucker device. The sucker type vacuum test mechanism has the advantages of simple operation, stable test, conservation of operation time and improvement of work efficiency.
Description
[technical field]
The present invention relates to a kind of vacuum test mechanism, particularly about a kind of sucked type vacuum test mechanism.
[background technology]
In the prior art, the method for waterproof product vacuum test commonly used is done air tightness test, and this vacuum test mechanism is fixed on the product to be measured through screw; As shown in Figure 1, it is a prior art vacuum test mechanism structural representation, and it comprises a wireway 2; This wireway one end is connected with a getter device (not shown), and the other end is fixed a draft hood 1, and this draft hood 1 is provided with 4 screw holes; Screw 101 is housed in this screw hole; Product 3 to be measured is connected fixing with above-mentioned draft hood 1 through above-mentioned 4 screws 101, yet the shortcoming of this structure is troublesome poeration, loses time.
In prior art, also have a kind of and fixing means product, being exactly the tester holds above-mentioned draft hood 1 with hand steered, reaches the purpose that itself and product to be measured are fixed.Yet this mode of operation is unstable, and test is fallen short of success for lack of final effort.
[summary of the invention]
The object of the present invention is to provide a kind of vacuum test mechanism, make it solve aforesaid operations trouble and problem of unstable.
For achieving the above object, the present invention provides a kind of sucked type vacuum test mechanism, and it comprises:
A draft hood;
A wireway, one of which end are connected fixing with above-mentioned draft hood top, the other end connects an air extractor;
An Acetabula device, it is fixed in the bottom of above-mentioned draft hood.
Thus, above-mentioned Acetabula device is adsorbed on the product to be measured, through this Acetabula device inner air and outer air pressure difference product to be measured is fixed on the above-mentioned Acetabula device firmly.
Compared to prior art, sucked type vacuum test mechanism provided by the invention is simple to operate, and stable testing has been saved the running time, has improved work efficiency.
[description of drawings]
Fig. 1 is a prior art vacuum test mechanism structural representation.
Fig. 2 is the sucked type vacuum test mechanism first embodiment perspective view of the present invention.
Fig. 3 analyzes structural representation for sucked type vacuum test mechanism first embodiment of the present invention.
Fig. 4 is the sucked type vacuum test mechanism second embodiment perspective view of the present invention.
[embodiment]
See also Fig. 2 and shown in Figure 3, it is respectively the perspective view and analysis structural representation of sucked type vacuum test mechanism first embodiment of the present invention, and this sucked type vacuum test mechanism comprises:

During test; With above-mentioned ring shaped air-cushion 30 and 4 airtight connections of product to be measured; Start the air extractor (not shown) of above-mentioned connection second wireway 32; Above-mentioned ring shaped air-cushion 30 gas inside are extracted out,, realize the purpose that above-mentioned ring shaped air-cushion 30 and product 4 to be measured are fixed through the pressure difference of above-mentioned ring shaped air-cushion 30 inner air and outer air.
See also shown in Figure 4ly, it is the sucked type vacuum test mechanism second embodiment perspective view of the present invention, and above-mentioned Acetabula device also can be a ring shaped air-cushion 3, and it is fixed on the bottom of above-mentioned draft hood 1.
During test, above-mentioned ring shaped air-cushion is connected with product 4 to be measured, pushes above-mentioned ring shaped air-cushion with hand its internal gas is extruded,, realize the purpose that above-mentioned ring shaped air-cushion and product to be measured 4 are fixed through the pressure difference of above-mentioned ring shaped air-cushion inner air and outer air.
Compared to prior art, sucked type vacuum test mechanism provided by the invention is simple to operate, and stable testing has been saved the running time, has improved work efficiency.
