Technical Field

[0001] The utility model relates to the technical field of sealing auxiliary tools for electrical wiring holes of rail transit vehicles, in particular to a sealing glue blocking device for upper wiring holes. Background Art

[0002] At present, when urban rail and transportation vehicles are produced, the wires used to connect electrical equipment need to pass through the upper wire holes on the vehicle end to achieve electrical connection between the equipment inside and outside the vehicle. In order to ensure the airtightness of the vehicle, the wire holes inside and below the vehicle need to be sealed with A365 glue after the wiring harness is completely installed on the vehicle. Since the upper wire hole is a through hole inside and below the vehicle, the A365 glue is in a fluid state. In the traditional way, before pouring the glue, it is necessary to use floor cloth waste cut into the corresponding shape as a temporary glue baffle to seal the lower part of the upper wire hole. In order to prevent the glue baffle from falling, a metal aluminum strip is used at the bottom for elastic support.

[0003] In the process of installing rubber baffles on traditional urban rail vehicles, it is necessary to use waste floor cloth from production to make temporary rubber baffles before installation. At the same time, aluminum strips are bent and shaped, and fixed inside the end electrical box by its elasticity to support the rubber baffles so that they will not fall off. This operation method has low work efficiency, poor stability, high labor intensity for operators, and is prone to colloid loss.

[0004] Therefore, how to solve the problem in the prior art that operators cannot quickly and reliably install the rubber baffle plate during installation of the rubber baffle plate has become an important technical problem that technical personnel in this field need to solve urgently. Utility Model Content

[0011] Furthermore, it also includes a sealing ring, which is evenly distributed on the upper surface of the first body and the second body, and forms a closed annular structure after the sealing rings are connected, the first body and the second body are located in the sealing ring to form an arc-shaped groove, and the two arc-shaped grooves form a threading hole after the first body and the second body are connected.

[0012] Furthermore, both the first body and the second body are quadrilateral plate-shaped structures, the upper surface of the quadrilateral plate-shaped structure is a plate surface, and the sealing ring protrudes from the upper surface of the plate surface.

[0013] Furthermore, the elastic component is a rubber block, and an abutment surface is formed at the end of the rubber block away from the support member, and an inclined surface extending obliquely upward is formed in the middle of the abutment surface.

At the same time, the elastic component at the end of the support member 2 is elastically deformed. The first body 1a and the second body 1b can generate an upward force by the elastic component while generating a horizontal force through the support member 2, so that the first body 1a and the second body 1b can abut against the end of the lower wire hole to seal it after docking.

The first body 1a and the second body 1b are located in the sealing ring 3 to form an arc-shaped groove. After the first body 1a and the second body 1b are connected, the two arc-shaped grooves form a threading hole 5, and the wiring harness can pass through the threading hole smoothly.
