Preferably, described pawl is formed by rectangular tube bending, while maintenance support performance, decreases three-piece wheel installing mechanism weight, reduces cost, improve efficiency.
More preferably, the end (even if used time and back-up ring contact jaw) of pawl, be provided with groove, the shape of groove shapes and retaining ring of rim projection adapts to, and during use, the easier fixed position of three-piece wheel installing mechanism, performance are more stable.
Preferably, described push rod is split-type structural, comprises pedestal, pawl, and be provided with hole in the middle of pedestal, pawl and base runner are installed.
Preferably, welded spanner outside described push nut, three-piece wheel installing mechanism uses more convenient.
Preferably, described pull bar two ends are provided with projection, its effect be pull bar and wheel rim increase when end contact is installed rub, anti-sliding stop.
Preferably, be provided with rectangular opening in the middle of described pull bar, screw mandrel lower end is cylindricality, and screw mandrel end is provided with screw thread, and pull bar is socketed in screw mandrel lower end by rectangular opening and is fixed by nut.Adopt this kind of structure, screw mandrel and pull bar are socketed closely, not easily rotate.
Preferably, the outside thread on described screw mandrel top is Acme thread, and push nut and screw mandrel screw togather, and adopts Acme thread not easy to wear, improves the service life of whole mechanism.
Adopt the three-piece wheel installing mechanism of said structure, after adopting this mechanism, change the mounting means of traditional three-piece wheel, reduce the labour intensity of personnel, improve the installation effectiveness of tire, reduce the recruitment cost of enterprise simultaneously.

Detailed description of the invention
Understand for the ease of persons skilled in the art and realize the utility model, now further describing three-piece wheel installing mechanism described in the utility model in conjunction with the drawings and the specific embodiments.
As shown in Figure 1, three-piece wheel installing mechanism, comprising: screw mandrel 1, push nut 2, push rod 4, pull bar 5; Wherein,
Screw mandrel 1 top is provided with outside thread (blocking by push nut 2, not shown), and in order to improve service life and the performance of whole mechanism, in the present embodiment, outside thread is Acme thread;
Screw mandrel 1 is sequentially sheathed from the top down push nut 2, bearing 3, push rod 4, pull bar 5, push nut 2 and screw mandrel 1 screw togather; In the present embodiment, sheathed bearing 3 between push nut 2, push rod 4, when push nut 2 is rotated, the stressed axis along screw mandrel 1 of bearing 3 moves down, and now, push rod 4 uniform force, three-piece wheel installing mechanism more flexibly, performance is more stable.
As shown in Figure 2, screw mandrel 1 end is provided with post ends 12 and screw thread 11, as shown in Figure 1, is provided with hole in the middle of pull bar 5, screw mandrel 1 end, through behind hole, is fixedly connected with pull bar 5, in the present embodiment by nut 13, in order to make screw mandrel 1 and pull bar 5 be socketed closely, not easily rotate, hole is rectangular opening.
As shown in Figure 2, push rod 4 is split-type structural, and comprise pedestal 41, pawl 42, pedestal 41 is placed through screw mandrel 1, and pawl 42 is the ends being socketed in pedestal 41.
