Description
Technical Field
The utility model belongs to the technical field of gas tightness check out test set and specifically relates to a gas tightness detects lift air guide device is related to.
Background
The air tightness test is required for the aerated product and the product with higher air tightness requirement before leaving the factory; it is common practice to flush the product with helium-containing air, then place the product in a sealed space, extract the air from the sealed space for a certain period of time, and test the air for the presence of helium.
However, in order to achieve the universality of the detection equipment, the sealing space of the detection equipment is usually made larger so as to adapt to products with different volumes, and during detection, the detection result has deviation due to the fact that the sealing space is larger, air suction is not uniform and the air leakage position is uncertain. Meanwhile, the sealed space of the detection equipment is not easy to move due to large volume; therefore, it is necessary to develop a detection device which is easy to move.
In order to reduce the production difficulty and the maintenance simplicity, it is necessary to design the detection device in a modular manner. The detection equipment usually comprises a sealing cover, an air pump and a helium mass spectrometer, the sealing cover and the air pump are connected through a pipeline, when the sealing cover is moved, the sealing cover and the air pump are connected together through the pipeline, the moving space of the sealing cover is limited, and the inseparable design also causes certain inconvenience in use and maintenance in the later period.
Disclosure of Invention
In view of this, there is a need for an air tightness detecting lifting air guide device with a modular design, a simple structure and a convenient use.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides an air tightness detects lift air guide device, includes elevating system, clamp plate and shrouding, clamp plate fixed connection is on elevating system, be connected through the spring between shrouding and the clamp plate, the shrouding middle part has a through-hole, and the through-hole in-connection has an air duct.
Further, the air duct is a hose.
Furthermore, the bottom surface of the sealing plate is provided with a sealing ring surrounding the through hole.
Further, the lifting mechanism is an air cylinder.
Furthermore, the bottom of a piston rod of the air cylinder is fixedly connected with a connecting frame, and the bottom of the connecting frame is fixedly connected with the pressing plate.
Furthermore, the pressure plate is provided with an avoiding groove for the air duct to pass through.
Compared with the prior art, the utility model discloses following beneficial effect has: the device is in modular design, is matched with the sealing cover of the air tightness detection equipment for use, and has simple structure and convenient use.
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic structural view of the embodiment of the present invention after removing the air duct.
Fig. 3 is a cross-sectional view of an embodiment of the present invention.
In the figure: 1-cylinder, 2-connecting frame, 3-pressing plate, 31-avoiding groove, 4-spring, 5-sealing plate, 51-through hole, 52-sealing ring, 6-air duct, 7-air collecting part, 71-air collecting groove and 72-air collecting hole.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1-2, the air tightness detection lifting air guide device comprises a lifting mechanism, a connecting frame 2, a pressure plate 3, a sealing plate 4 and an air guide tube 6.
The lifting mechanism adopts a cylinder 1, the bottom of a piston rod of the cylinder 1 is fixedly connected with the top of a connecting frame 2, the bottom of the connecting frame 2 is fixedly connected with the top surface of a pressing plate 3, and the bottom surface of the pressing plate 3 is elastically connected with the top surface of a sealing plate 5 through four springs 4 (top springs).
The closing plate 5 has a through hole 51 in the middle, and the through hole 51 is used for connecting the air duct 6.
In this embodiment, the bottom surface of the sealing plate 5 has a sealing ring 52 surrounding the through hole.
In this embodiment, the connecting frame 2 is in a shape of a Chinese character ji, and the structure of the connecting frame 2 can provide an avoiding space for the bending part of the air duct 6.
In this embodiment, the pressure plate 3 has an escape groove 31 through which the gas duct 6 passes.
As shown in fig. 3, when the device is used, the top of the lifting mechanism is fixedly connected to a frame, the top of the sealed cover is fixedly connected with the gas collecting part 7, the peripheral side wall and the inner bottom of the gas collecting part 7 are provided with gas collecting holes 72, the gas collecting holes 72 are communicated with all parts of the top of the sealed cover through pipelines, and further communicated with the inside of the sealed cover, and the gas collecting holes 72 collect the gas extracted from the sealed cover into a gas collecting groove 71 of the gas collecting part 7. When the closing plate 5 descends to the bottom, the closing plate 5 seals the notch of the gas collecting groove 71 (the sealing ring has a better sealing effect); the air duct 6 passes through the closing plate 5 and is communicated with the air collecting groove 71, and the other end of the air duct 6 is connected with the air pump.
The pressing plate 3 is connected with the sealing plate 5 through the spring 4, so that the sealing plate 5 is elastically connected when sealing the gas collecting groove 71, rigid collision can not occur, and the equipment is damaged.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
