AI Technical Summary
In traditional GRE pipe connection methods, the adhesive can easily introduce air bubbles during the insertion process, resulting in reduced bonding effect, insufficient sealing, and the joint is prone to detachment due to vibration or impact.
The design employs an inner layer and insert strip, which increases the contact area through the snap-fit structure of the inner layer and insert strip. With the help of adhesive, the connection strength is enhanced by matching the shape and size of the inner layer and insert strip. Adhesive is also applied to the contact surface to ensure a tight connection.
It enables simple operation without being limited by the on-site work space, ensures tight and secure connection between ports, has high connector reliability, is not easy to detach, and has a neat appearance.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of composite material connection technology, specifically, it relates to a fixed insertion structure for GRE pipe connectors. Background Technology
[0002] The traditional method for connecting GRE pipe fittings is as follows: the outer wall of the GRE pipe is ground into a conical shape, the outer wall of the connecting sleeve is ground into a conical shape, adhesive is evenly applied to the conical opening, and then the GRE pipe is pushed in along the conical opening until it is fully engaged and left to cure. However, when pushing the GRE pipe in along the conical surface, some air is introduced, causing local air bubbles in the adhesive, which reduces the bonding effect and actual sealing performance of the adhesive. This can easily lead to the risk of the joint coming apart and leaking due to vibration or impact. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a GRE pipe connector fixed plug-in structure, including port one, port two and adhesive. Port one and port two are respectively provided with annular inner layer one and inner layer two, and inner layer one and inner layer two are correspondingly abutted. Insert strip one and spacer one are evenly distributed on the outer side of inner layer one, and insert strip two and spacer two are evenly distributed on the outer side of inner layer two. Insert strip two matches and is correspondingly snapped with spacer one, and insert strip one matches and is correspondingly snapped with spacer two. An annular sleeve is fixedly provided on the outer side of port one, and adhesive is applied to the inside of spacer one and spacer two.
[0004] Furthermore, the first and second inserts are identical in shape and size, and the first and second ports can be slightly rotated to find the interlocking position. The adhesive applied in the first and second gaps ensures that the first and second inserts are tightly bonded together.
[0005] Furthermore, the lengths of inner layer one and inner layer two are half the length of insert one. During the process of connecting port one and port two, while inner layer one and inner layer two abut against each other, insert one and insert two also abut against each other tightly.
[0006] Furthermore, the length of the sleeve is greater than the length of the insert, and the right end of the sleeve is fitted onto the outside of the interface of port one and port two to further fix the interface of port one and port two.
[0007] Furthermore, the inside of the sleeve is coated with adhesive to bond the outer sides of insert one, insert two, and port two to the sleeve. Sufficient adhesive is applied to the inside of the sleeve, with excess adhesive overflowing from the sleeve to ensure a secure connection.
[0008] Furthermore, adhesive is applied to the joint between inner layer one and inner layer two.
[0009] This invention also includes other devices or components that enable the GRE pipe connector fixed plug structure to function properly, all of which are conventional techniques in the field. Furthermore, the sleeves and adhesives not specified in this invention also employ conventional techniques in the field.
[0010] The working principle of this utility model is that the device uses inner layer one, inner layer two, insert one and insert two to snap port one and port two together, and increases the contact area between port one and port two. Adhesive is applied between the contact surfaces of each component to ensure that port one and port two are tightly connected.
[0011] The beneficial effects of this utility model are that the device is not affected by the on-site working space, the operation is relatively simple when plugging in port one and port two, and it can ensure that port one and port two are tightly snapped and firmly glued, the reliability of the connector is high, the interface between port one and port two will not detach after a period of use, and the interface is clean and tidy.

[0019] like Figures 1-4As shown, the present invention provides a GRE pipe connector fixing and plugging structure, including port 1, port 2 and adhesive 3. Port 1 and port 2 are respectively provided with annular inner layer 4 and inner layer 5, and inner layer 4 and inner layer 5 are correspondingly abutting. Insert strip 6 and spacer 7 are evenly distributed on the outer side of inner layer 4, and insert strip 8 and spacer 9 are evenly distributed on the outer side of inner layer 5. Insert strip 8 matches and is correspondingly snapped with spacer 7, and insert strip 6 matches and is correspondingly snapped with spacer 9. An annular sleeve 10 is fixedly provided on the outer side of port 1. Adhesive 3 is applied to the inside of spacer 7 and spacer 9.
[0020] As a further measure of this utility model, the first insert 6 and the second insert 8 are the same in shape and size, and the first port 1 and the second port 2 can be slightly rotated to find the position where they interlock. The adhesive 3 applied in the first spacer 7 and the second spacer 9 makes the first insert 6 and the second insert 8 stick together tightly. The length of the first inner layer 4 and the second inner layer 5 is half the length of the first insert 6. During the process of connecting the first port 1 and the second port 2, while the first inner layer 4 and the second inner layer 5 abut against each other, the first insert 6 and the second insert 8 also abut against each other tightly. The length of sleeve 10 is greater than the length of insert 6, and the right end of sleeve 10 is fitted over the outside of the interface of port 1 and port 2 to further fix the interface of port 1 and port 2; the inside of sleeve 10 is coated with adhesive 3 to bond the outside of insert 6, insert 8, and port 2 to sleeve 10, and the inside of sleeve 10 is coated with enough adhesive 3, with excess adhesive 3 overflowing from sleeve 10 to ensure a firm connection; the abutment of inner layer 4 and inner layer 5 is coated with adhesive 3.
