Description

Technical Field

[0001] The invention relates to the technical field of expansion rubber strips, and in particular to an expansion rubber strip connection structure. Background Art

[0002] Water-swelling waterstop is a general term for putty-type waterstop and product-type waterstop with water-swelling properties. Water-swelling rubber putty has both the good adhesion and low-temperature performance of general putty and good expansion characteristics. This product is synthesized from a variety of polymer chemical materials and has higher strength than general putty. It is particularly suitable for waterproofing projects. This product can be produced according to the specifications and models required by users and designs. The finished product is generally wound into a disc and packed in cartons for easy transportation.

[0003] When two water pipes are connected, the expansion strip will be compressed at the connection point of the two pipes. When the expansion strip encounters water, it will expand, and the compressed area is easily torn by the expansion, resulting in poor sealing. Therefore, in order to solve this problem, we propose an expansion strip connection structure. Summary of the invention

[0004] The invention provides an expansion rubber strip connection structure, which solves the problem that the compression part of the expansion rubber strip is easy to be torn and has poor sealing performance.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An expansion rubber strip connection structure comprises a transport pipeline, a connecting pipeline is arranged on one side of the transport pipeline, an expansion rubber body is arranged between the transport pipeline and the connecting pipeline, a threaded ring is arranged at one end of the connecting pipeline close to the transport pipeline, a limiting groove is arranged on the side wall of the expansion rubber body, and the limiting groove is symmetrically arranged with the central axis of the expansion rubber body, and a stabilizing plate and a limiting plate are respectively arranged at the ends of the transport pipeline and the connecting pipeline close to each other, and the stabilizing plate and the limiting plate are matched with the limiting groove.

[0007] Preferably, the transport pipeline and the connecting pipeline are both provided with transport channels.

[0008] Preferably, a mounting plate is fixedly mounted on one end of the transport pipeline close to the connecting pipeline, and the threaded ring matches the mounting plate.

[0009] Preferably, a placement groove is formed between the transport pipe and the stabilizing plate and the connecting pipe and the limiting plate, and the placement groove matches the expansion rubber body.

[0010] Preferably, a steel wire mesh is provided inside the expansion rubber body, the steel wire mesh is symmetrically arranged with respect to the central axis of the expansion rubber body, and the steel wire mesh is located at the extrusion position between the transport pipe and the connecting pipe.

[0011] Preferably, a fixing block is arranged inside the expansion rubber body, the fixing block is symmetrically arranged with respect to the central axis of the expansion rubber body, and the expansion rubber body is arranged in an I-shape.

[0012] The beneficial effects of the present invention are:

[0013] 1. Place the expansion rubber body in the placement groove, then clamp the limit groove on the expansion rubber body on the stabilizing plate, and then rotate the connecting pipe. The connecting pipe drives the threaded ring to be threaded on the mounting plate, thereby effectively fixing the connecting pipe on the transport pipe.

[0014] 2. The expansion rubber body is squeezed through the limiting plate, and then the strength of the expansion rubber body is increased through the wire mesh, thereby effectively reducing the problem of easy tearing at the compressed part.

[0015] 3. Due to the characteristic of the expansion rubber body that it expands when it encounters water, when the expansion rubber body encounters water, the expansion rubber body will expand, and after expansion, it will seal the connection between the transport pipe and the connecting pipe, and then the expansion rubber body in the placement groove will also expand, thereby filling the entire placement groove, and then the fixed block can limit the expansion position of the expansion rubber strip, so that the expansion rubber strip spreads around, thereby effectively improving the sealing between the pipeline connections.

[0016] In summary, the device can effectively reduce the problem of easy tearing of the compression part, and can effectively improve the sealing between the pipeline connections, while effectively fixing the connecting pipeline on the transport pipeline for easy use.
