Embodiment
In order to make to want the object of utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model provides a kind of extruded connection connector embodiment.
This extruded connection connector comprises: with the cylindric hollow cylinder 1 in sleeve A, and withhold one end in the socket of this cylindrical shell 1 and be provided with locating ring 10, described cylindrical shell 1 is provided with the less groove of wall thickness 12 along its length.
Specifically, when extruded connection connector is for connecting two sleeve pipes, being respectively equipped with locating ring 10 at the two ends of cylindrical shell 1, can, at the impression of the surperficial formation rule of cylindrical shell 1, occurring departing from when avoiding withholding when this locating ring 10 is for withholding, effect is withheld in impact.When extruded connection connector is for connecting a sleeve pipe, establish locating ring 10 in cylindrical shell 1 one end.Described cylindrical shell 1 is provided with inwardly protruded annular relief 11, the height of this annular relief 11 is identical with the wall thickness of sleeve pipe, ensure to withhold with sleeve pipe fixing after, smooth connection is formed in the end of sleeve pipe, avoid the sliding broken electric wire epidermis of the end out-of-flatness of the sleeve pipe when threading, cause electric leakage risk.Described annular protrusion 11 cross section is hemispherical or convex structure.
When withholding, cylindrical shell 1 is enclosed within sleeve pipe, extruded outside cylindrical shell 1 by special instrument of withholding again, its local is radially shunk, and due to straight slightly large usually than sleeve pipe of cylindrical shell 1, only needing cylindrical shell 1 to withhold position has certain distortion, and form extruding trace 13 on cylindrical shell 1 surface, close contact can be formed with sleeve A surface, realize withholding, as shown in Figure 3 and Figure 4.Simultaneously because gap between cylindrical shell 1 and sleeve pipe is less, shunk to extruding by cylindrical shell 1, make the gap of originally depositing become less or not exist, avoid when pre-buried, occur that cement mortar enters in sleeve pipe, avoid the potential safety hazard occurring electric leakage.Simultaneously because cylindrical shell 1 is provided with the less groove of wall thickness 12 along its length, when cylindrical shell 1 pressure extrusion, inside contraction is there is at groove 12, make to form bow strip structure 14 at sleeve surface, as Fig. 5, make cylindrical shell 1 and sleeve pipe form good electrical continuity, and its electrical continuity need not be ensured by external wire again, reduce installation procedure, improve installation effectiveness.
As shown in Figure 6, basis is novel also provides a kind of extruded connection connector special fixing device embodiment.
This extruded connection connector special fixing device comprises: the depression bar 2 of two synchronous axial system and the connection fixture 5 be connected with depression bar 2, this connection fixture 5 is connected with the hydraulic cylinder 8 being fixed with pressing mould B, the fixed part coordinated with pressing mould B is had at this hydraulic cylinder upper cover of piston rod, the rotation section 41 that this fixed part comprises fixed body 4 and is rotatably assorted with fixed body 4, be provided with for fixing snap part 7 between fixed body 4 and rotation section 41, be provided with connecting rod 3 at described depression bar 2 and fixed body 4.
Specifically, described hydraulic cylinder 8 one end is connected with movable pressing mould B, and the other end is connected with connection fixture 5, and this connection fixture 5 is flexibly connected respectively with two depression bars 2.Described depression bar 2 is also flexibly connected with fixed body 4 by connecting rod 3.
Fixed with fixed body 4 and fixed body 4 respectively by the pressing mould B coordinated with extruded connection connector during use, namely pressing mould B is made up of two semicircle moulds.First connector is placed in semicircle mould, by snap part 7, fixed part is locked again, again two depression bars 2 are moved inward, make between hydraulic cylinder piston rod with fixed body 4 dynamic mobile mutually, namely hydraulic cylinder piston rod makes an outside mobile compression connector of circular dies, make its die location occur extruding contraction distortion, realization is withheld fixing.
In order to make guarantee hydraulic cylinder piston rod or semicircle mold movement steadily, described fixed body 4 is provided with the guiding mechanism (accompanying drawing does not indicate) coordinated with pressing mould B, and this guiding mechanism comprises gathering sill or gib block.Between two depression bars 2, be provided with synchromesh gear 6, two depression bar energy synchronizing movings can be protected, thus ensure hydraulic cylinder piston rod both sides stress balance.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
