Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): the utility model provides a drain pipe seal ring, as shown in fig. 1 and fig. 2, contain the drain pipe 2 of wearing to establish concrete 1, it has the solid fixed ring 3 with drain pipe 2 assorted to bond through waterproof glue 6 respectively on the drain pipe 2, gu fixed ring 3 is the same material with drain pipe 2, two solid fixed ring 3 are located concrete 1's both sides respectively, gu fixed ring 3 bonds respectively towards concrete 1's terminal surface has rubber pad 4 for two, gu fixed ring 3 evenly has seted up four seal grooves 7 on deviating from the terminal surface of rubber pad 4, wear to be equipped with screw 5 respectively in four fixed slots, the cover is equipped with on screw 5 with the sealed pad 8 of seal groove 7 assorted, sealed pad 8 is made by rubber.

As shown in fig. 2, the two fixing rings 3 are connected to the concrete 1 by four screws 5 passing through the fixing rings 3 and the rubber pad 4 at the same time and bolted into the concrete 1, the sealing pad 8 is tightly pressed in the sealing groove 7 by the end of the screw 5, and the rubber pad 4 is tightly pressed between the fixing rings 3 and the concrete 1. Therefore, when a gap occurs between the drain pipe 2 and the concrete 1 due to a temperature decrease, the connection gap between the fixing ring 3 and the drain pipe 2 is sealed by the waterproof glue 6, so that external water is difficult to leak from the connection gap between the fixing ring 3 and the drain pipe 2; the two ends of the connecting gap between the drain pipe 2 and the concrete 1 are respectively sealed by two rubber pads 4 tightly abutted against the concrete 1, so that external water is difficult to leak from the connecting gap between the drain pipe 2 and the concrete 1, the connecting part of the drain pipe 2 and the concrete 1 has a good waterproof effect, and the possibility that the waterproof effect of a concrete structure is damaged due to the gap between the drain pipe 2 and the concrete 1 when the temperature is reduced; the sealing gasket 8 has the effect of sealing the screw 5, so that external water is difficult to leak from the joint of the screw 5, and the waterproof effect of the joint of the drain pipe 2 and the concrete 1 is further enhanced.

As shown in fig. 3 and fig. 4, a drain pipe seal ring, still contain eight fixed plates 9, evenly set up four square spread groove 13 on two solid fixed ring 3 deviates from the terminal surface of rubber pad 4 respectively, set firmly spliced pole 12 with spread groove 13 assorted on eight fixed plates 9 respectively, eight fixed plates 9 correspond the mode of interference fit grafting in eight spread groove 13 through eight spliced poles 12 respectively and solid fixed ring 3 interconnect, wear to establish and threaded connection has the tight axle 10 of support towards 5 directions of screw on eight fixed plates 9 respectively, the position of supporting tight axle 10 is set up to: when the fixing plate 9 is connected with the fixing ring 3 in a manner that the connecting column 12 is inserted into the connecting groove 13, a gap is formed between the abutting shaft 10 and the end face of the fixing ring 3, which is far away from the rubber pad 4; the end part of the abutting shaft 10 far away from the screw 5 is fixedly provided with an extension rod 11, and the arrangement of the extension rod 11 enables a worker to rotate the abutting shaft 10 through the extension rod 11 in a labor-saving manner. Therefore, after the fixing plate 9 and the fixing ring 3 are connected with each other by the worker, the tightening shaft 10 can be driven to rotate by rotating the extension rod 11 until the tightening shaft 10 is tightened on the screw 5 towards one end of the screw 5, so that the screw 5 is difficult to rotate relative to the tightening shaft 10, and the possibility that the fixing ring 3 is loosened due to loosening of the screw 5 is reduced.

As shown in fig. 4, the fixing plate 9 is connected with the fixing ring 3 through the connecting column 12 in the connecting groove 13 in an inserting mode, so that the fixing plate 9 and the tightening shaft 10 can be integrally detached from the fixing ring 3 through a mode that a worker can pull the connecting column 12 out of the connecting groove 13 by grabbing the fixing plate 9 with force, the worker can conveniently separate and store a plurality of fixing rings 3 and the fixing plate 9 when transporting the drain pipe 2 and the fixing rings 3, the transporting space is saved, and the transporting cost is reduced.

As shown in fig. 2, the annular groove 14 has been seted up along the inner periphery on the terminal surface that solid fixed ring 3 deviates from rubber pad 4, still overlaps on the drain pipe 2 to be equipped with the waterproof pad 15 of annular that is made by rubber, and waterproof pad 15 is supported tightly and is placed in annular groove 14, and waterproof pad 15 is set up to: when the waterproof pad 15 is tightly pressed in the annular groove 14, the inner edge of the waterproof pad 15 is tightly pressed on the outer periphery of the drain pipe 2, and the outer edge of the waterproof pad 15 is tightly pressed on the annular side wall of the annular groove 14. Therefore, when waterproof glue 6 is ageing to lead to waterproof glue 6 to locate drain pipe 2 and the solid fixed ring 3 between sealed effect reduce, waterproof pad 15 supports tightly on drain pipe 2 and makes and still have good sealed waterproof nature between drain pipe 2 and the solid fixed ring 3 to the leakproofness between drain pipe 2 and the solid fixed ring 3 has further been strengthened, after having reduced long-time the use, waterproof glue 6 is ageing to lead to being difficult to seal between drain pipe 2 and the solid fixed ring 3, influence drain pipe 2 and concrete 1 junction water-proof effects's possibility.

As shown in fig. 2, an annular connecting plate 17 is further bolted to the end face of the fixing ring 3 away from the rubber pad 4, an annular limiting plate 16 having an inner edge flush with the inner edge of the fixing ring 3 is fixedly arranged on the annular connecting plate 17, and the annular limiting plate 16 is located in the annular groove 14 and tightly abuts against the waterproof pad 15. Therefore, when the waterproof pad 15 is twisted and deviated outwards from the annular groove 14 under the action of external force, the waterproof pad is blocked by the limiting plate 16, and the limiting plate 16 plays a role in limiting the waterproof pad 15, so that the waterproof pad 15 can be always tightly pressed and coated on the drain pipe 2 to seal a connecting gap between the fixing ring 3 and the drain pipe 2; meanwhile, the connecting plate 17 and the limiting plate 16 can be detached from the fixing ring 3 by the worker regularly in a bolt detaching mode, so that the worker can replace the aged waterproof pad 15, and the possibility that the sealing effect between the fixing ring 3 and the drain pipe 2 is reduced due to the fact that the waterproof pad 15 is aged is reduced.

The implementation principle of the embodiment is as follows: when the fixing ring 3 needs to be installed, a worker can firstly fixedly connect the fixing ring 3 into the concrete 1 through the screw 5, coat the waterproof glue 6 at a connecting gap between the fixing ring 3 and the drain pipe 2, and then sequentially install the waterproof pad 15 and the connecting plate 17 to complete the installation of the fixing plate 9; the solid fixed ring 3 is the same material with drain pipe 2, when the temperature reduces, gu fixed ring 3 is the same with the shrinkage between the drain pipe 2, gu fixed ring 3 is sealed by waterproof glue 6 and waterproof pad 15 simultaneously with the joint gap between drain pipe 2, rubber pad 4 is supported tightly and has played the sealed effect of the joint gap between solid fixed ring 3 and concrete 1, thereby make when the temperature reduces because the different gap both ends that produce of shrinkage can be sealed by rubber pad 4 and solid fixed ring 3 between concrete 1 and the drain pipe 2, outside water is difficult to make the junction of drain pipe 2 and concrete 1 have good water-proof effects in order to enter into the joint gap between concrete 1 and the drain pipe 2, when having reduced the temperature and reducing, appear the gap between drain pipe 2 and the concrete 1, destroy concrete structure water-proof effects's possibility.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
