Detailed Description

The present application is described in further detail below with reference to figures 1-4 of the specification.

The embodiment of the application discloses integrative iron frame structure of glued membrane. The integrated iron frame structure of the rubber and the iron comprises an iron frame 1, and a rubber frame 2 is arranged in the iron frame 1. Iron frame 1 includes bottom plate 13 and curb plate 14, and curb plate 14 sets up around bottom plate 13, and this embodiment adopts integrated into one piece to set up. Set up drawing of a plurality of quantity on chase 1 and glue hole 11, the colloid is moulded plastics through respectively drawing gluey hole 11 and is glued frame 2 in 1 formation of chase, glues 2 shaping backs, connects the colloid of gluing frame 2 and also can be connected with drawing gluey hole 11, has strengthened being connected of gluing frame 2 and chase 1 for it is more firm to glue frame 2 and chase 1 combination.

Still seted up spread groove 12 on the chase 1, glued frame 2 and gone up integrated into one piece and have joint piece 21, joint piece 21 is located spread groove 12 and is connected with chase 1, spread groove 12 and joint piece 21's setting, has increased the area of contact who glues frame 2 and chase 1, through mutually supporting with drawing gluey hole 11, has further increased the joint strength who glues frame 2 and chase 1, has improved and has glued frame 2 and the poor defect of chase 1 connection leakproofness.

The rubber frame 2 covers the inner side wall and the upper surface of the side plate 14 of the iron frame 1, and the rubber frame 2 also covers the bottom plate 13. Because the connecting groove 12 sets up on bottom plate 13 for glue the joint piece 21 of frame 2 and can fill in whole connecting groove 12, glue frame 2 simultaneously and can also cover the both sides of connecting groove 12. Due to the existence of the connecting groove 12, the iron exposure condition of the rubber frame 2 caused by inward shrinkage of the surface glue position is reduced, and the problem of iron exposure on the surface of the rubber frame is solved.

The iron frame 1 is also provided with a plurality of forming holes 15, and each forming hole 15 is positioned on the bottom plate 13. The shape of the molding holes 15 may be circular, square, and irregular, whereas the shape of the molding holes 15 employed in the embodiment of the present application is semicircular. Glue frame 2 at injection moulding's in-process, in part colloid also can flow into shaping hole 15, glue frame 2 cooling shaping back, glue frame 2 and can be connected with shaping hole 15, further strengthened gluey frame 2 and iron frame 1's joint strength.

This application is the annular groove at the connecting groove 12 that sets up on chase 1, and connecting groove 12 can set to square corner or fillet according to chase 1's appearance in chase 1's corner, and in this application embodiment, the connecting groove 12 of adoption is the fillet in the corner.

Through holes or accommodating grooves 121 can be formed in the bottom wall or the side wall of the connecting groove 12, while the accommodating grooves 121 are formed in the side wall of the connecting groove 12, and the connecting groove 12 is communicated with the accommodating grooves 121 in the embodiment of the present application. In the present application, the receiving groove 121 is shaped like a cylinder and is provided along the length direction of the coupling groove 12. The cross section of the accommodating groove 121 is a broken hole shape, and the broken hole shape is a C-like shape. In the embodiment of the present application, the width of the opening of the accommodating groove 121 is smaller than the diameter of the hole breaking structure. When moulding plastics and forming gluey frame 2, the colloid can enter into the connecting groove 12 at first and form joint piece 21 in, and the colloid can continue to enter into the holding tank 121 and form joint 211 in succession, and gluey frame 2 is behind the shaping, and the diameter of the cross section of the joint 211 that is located the holding tank 121 can be greater than the width of passageway for joint 211 that is located the holding tank 121 is difficult to come out from holding tank 121. The contact area between frame 2 and chase 1 can be further increased in the setting of holding tank 121 to further increase gluey frame 2 and chase 1's joint strength.

The implementation principle of the integrative iron frame structure of this application embodiment is: glue frame 2 in injection moulding process, the colloid can enter into earlier and form joint piece 21 in the spread groove 12, then enter into the holding tank 121 and form joint 211, after gluing frame 2 cooling forming, the joint piece 21 that is located spread groove 12 and the joint 211 that is located holding tank 121 also can cooling forming, joint piece 21 and joint 211 have improved the area of contact who glues frame 2 and chase 1, the joint strength who glues frame 2 and chase 1 has also been strengthened simultaneously, the sealing performance who glues frame 2 and chase 1 and be connected has further been improved.
