Waterproof of the present utility model is ejector rob trolley provided, comprise car body and tailstock, inner conduit is provided with in described car body, described tailstock is fixedly installed on the right-hand member of car body, tailstock is provided with the first through hole, described first through hole extends to the right flank of tailstock from the left surface of tailstock, and the first through hole communicates with the inner chamber of car body, described waterproof is ejector rob trolley provided also comprises connector, gland and and to silk, described connector is fixedly installed on the right flank of tailstock, and connector is positioned at the first through hole of tailstock, the right surface of described connector offers storage tank, the right-hand member of described inner conduit is each passed through the first through hole of tailstock and connector and stretches in storage tank, one end being positioned at storage tank of inner conduit is also provided with back-up ring, described back-up ring is fixedly installed on the lateral surface of inner conduit, the left surface of back-up ring contacts with the bottom surface of storage tank, the lateral surface of back-up ring contacts with the medial surface of storage tank, described gland is threaded connection on connector, gland offers the second through hole, described second through hole communicates with storage tank, the left surface of gland contacts with the right flank of back-up ring, described right-hand member silk being connected to gland, be threaded connection in the second through hole to one end of silk, be used for being connected with external water source to the other end of silk.
Further, waterproof of the present utility model is ejector rob trolley provided, and the right side of described inner conduit is inclined plane.
Further, waterproof of the present utility model is ejector rob trolley provided, and the left surface of described gland offers the holddown groove of annular, the sidewall of connector is arranged in holddown groove, the lateral surface of connector is provided with external screw thread, and the medial surface of holddown groove is provided with the internal thread suitable with the external screw thread of connector.
By such scheme, the utility model at least has the following advantages: waterproof of the present utility model is ejector rob trolley provided to be comprised car body and be fixedly installed on the tailstock on car body, inner conduit is provided with in car body, the right flank of tailstock is provided with connector, the surface that has of connector is uply provided with storage tank, the right-hand member of inner conduit passes from the first through hole tailstock and stretches in storage tank, one end being positioned at storage tank of inner conduit is fixed with back-up ring, the left surface of back-up ring contacts with the bottom surface of storage tank, the lateral surface of back-up ring contacts with the medial surface of storage tank, the right flank of back-up ring contacts with the left surface of gland, gland is threaded connection on connector, be provided with silk in second through hole of gland.During concrete use, external water source is through directly arriving the right-hand member of inner conduit to silk, due to the effect of gland, the left surface of baffle plate fits tightly on the bottom surface of storage tank, the right flank of baffle plate is closely fitted on the left surface of gland, thus form a mazy structure, water is difficult in the tailstock that enters from the side of tube wall, thus enhance ejector rob trolley provided water resistance, add ejector rob trolley provided service life, and waterproof of the present utility model its inner conduit ejector rob trolley provided no longer adopts original flange form syndeton, just fixed by connector and gland, structure is simple, be convenient to safeguard and manufacture and reduce cost.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
