Abstract
Description
Technical Field
[0001] This utility model relates to the field of aviation plug sealing technology, specifically to an aviation plug vacuum sealing and pressurizing potting device. Background Technology
[0002] Vacuum aviation connectors operate in atmospheric pressure on one side and a high vacuum environment on the other. These operating conditions place stringent requirements on the manufacturing and subsequent processing of aviation connectors.
[0003] Currently, when sealing aviation connectors, potting compound is usually injected directly into the interior of the connector. During the curing process, the potting compound relies solely on its own settling, which is not conducive to fully sealing the small gaps inside the connector, resulting in a generally poor sealing effect. Utility Model Content
[0004] The purpose of this invention is to provide a vacuum sealing and pressurizing potting device for aviation plugs to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum sealing and pressurizing potting device for an aviation plug, comprising a plug body and a connecting plate. An armature tube is fixed to the outer side of the upper end of the plug body, and a support ring is provided at the outer bottom end of the armature tube. A first through hole is opened at the outer end of the support ring. A pressure plate is provided on the upper part of the armature tube, and a sealing tube is fixed to the inner side of the pressure plate. A connecting plate is connected to the top of the sealing tube, and a connecting hole is opened in the middle of the connecting plate.
[0006] Furthermore, the outer diameter of the sealing tube is smaller than the inner diameter of the armature tube, and the axis of the sealing tube coincides with the axis of the armature tube.
[0007] Furthermore, a second through hole is provided at the outer end of the pressure plate, and the second through hole corresponds one-to-one with the first through hole.
[0008] Furthermore, a bolt passes through the interior of the second through hole, and the cylindrical head of the bolt abuts against the bottom of the support ring.
[0009] Furthermore, the outer diameter of the pressure plate is equal to the outer diameter of the support ring, and the bolts are distributed equidistantly in a circular pattern along the top surface of the pressure plate.
[0010] Furthermore, a nut is threaded onto the upper outer side of the bolt, and the nut abuts against the pressure plate.
[0011] Furthermore, a sealing groove is provided at the bottom of the pressure plate, and the sealing groove is annular.
[0012] Furthermore, a sealing ring is fitted inside the sealing groove, and the sealing ring is tightly fitted with the armature tube.
[0013] This utility model provides a vacuum sealing and pressurizing potting device for aviation plugs, which has the following beneficial effects:
[0014] 1. By setting up a sealing tube, when the sealant needs to be cured after being injected into the armature tube, bolts and nuts can be used to clamp the armature tube with the pressure plate and the support ring. At this time, the external gas pipeline connector is connected to the connecting plate through the threaded connecting hole. Then, compressed gas is introduced into the sealing tube, which can use the compressed gas to squeeze the sealant, achieving the effect of a dense sealing layer and filling even small gaps, thereby improving the overall sealing quality of the aviation plug.
[0015] 2. By setting a sealing ring, this utility model can improve the sealing performance between the pressure plate and the armature tube, and avoid gas leakage during the pressure curing process. At the same time, by setting multiple bolts, the pressure plate and the support ring are evenly stressed and more stable, which is conducive to improving the sealing effect. In addition, the structure of this application is simple and very convenient to assemble and disassemble. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figures 1 to 3As shown, a vacuum sealing and pressurizing potting device for an aviation plug includes a plug body 1 and a connecting plate 7. An armature tube 2 is fixed to the outer upper end of the plug body 1, and a support ring 3 is provided at the outer bottom end of the armature tube 2. The support ring 3 can support the bottom of the armature tube 2. A first through hole 4 is opened at the outer end of the support ring 3. A pressure plate 5 is provided on the upper part of the armature tube 2, and a sealing tube 6 is fixed to the inner side of the pressure plate 5. The pressure plate 5 can limit the top of the armature tube 2. The outer diameter of the sealing tube 6 is smaller than that of the armature tube 2. The inner diameter of the conduit 2 and the axis of the sealing tube 6 coincide with the axis of the armature conduit 2. By inputting compressed gas into the sealing tube 6, the compressed gas can be used to squeeze the potting compound, achieving a dense sealing layer and filling even small gaps, thereby improving the overall sealing quality of the aviation plug. The top of the sealing tube 6 is connected to a connecting plate 7, and the middle of the connecting plate 7 is provided with a connecting hole 8, which can connect the gas supply pipe joint of the external pressure supply equipment to the connecting plate 7 through the threaded connecting hole 8.
[0023] like Figure 1 and Figure 4 As shown, the outer end of the pressure plate 5 has a second through hole 9, which corresponds one-to-one with the first through hole 4, facilitating subsequent connection. A bolt 10 passes through the second through hole 9, and the cylindrical head of the bolt 10 abuts against the bottom of the support ring 3. The outer diameter of the pressure plate 5 is equal to the outer diameter of the support ring 3, and the bolts 10 are equidistantly distributed circumferentially along the top surface of the pressure plate 5. The arrangement of multiple bolts 10 ensures uniform force distribution between the pressure plate 5 and the support ring 3, resulting in greater stability and improved sealing performance. A nut 11 is threaded onto the upper outer side of bolt 10, and the nut 11 abuts against the pressure plate 5. The pressure plate 5 and the support ring 3 can be clamped together by bolt 10 and nut 11. A sealing groove 12 is provided at the bottom of the pressure plate 5, and the sealing groove 12 is annular. A sealing ring 13 is embedded inside the sealing groove 12, and the sealing ring 13 is tightly fitted with the armature tube 2. The sealing performance between the pressure plate 5 and the armature tube 2 is improved by the sealing ring 13, and gas leakage is prevented during the pressure curing process.
[0024] In summary, when using this aviation plug vacuum sealing and pressurizing potting device, firstly according to... Figures 1 to 4The structure shown involves first inserting bolt 10 through the first through hole 4 into the retainer ring 3, then placing the armature tube 2 in the upper center of the retainer ring 3. Encapsulating adhesive is then injected into the upper part of the plug body 1 using an injection device. Next, bolt 10 passes through the second through hole 9 through the pressure plate 5, and nut 11 is used to clamp the armature tube 2 between the pressure plate 5 and the retainer ring 3. Then, the sealing ring 13 improves the sealing performance between the pressure plate 5 and the armature tube 2, preventing gas leakage during the pressure curing process. Simultaneously, the multiple bolts 10 ensure even force distribution between the pressure plate 5 and the retainer ring 3, resulting in greater stability and improved sealing. Finally, the gas supply pipe connector of the external pressure supply device is connected to the connecting plate 7 through the threaded connecting hole 8. Compressed gas is then introduced into the sealing tube 6, which compresses the encapsulating adhesive, achieving a dense sealing layer that fills even small gaps, thereby improving the overall sealing quality of the aviation plug.
