A functional section 122 can surround the node 121 being connected with the functional section 122 and rotate, and locking device is provided with node 121,
Locking device is used for fixed function section 122；The directive wheel 2 is installed on the vertical pole 12, is coaxially felt at ease with the vertical pole 12
Dress；Vertical pole 12 is flexibly connected with directive wheel 2, and directive wheel 2 can be rotated centered on vertical pole 12.
In the present embodiment, Fig. 2 is the structure diagram of the railway freight-car leading block cross bar 11 of the utility model.Referring to
Fig. 2, cross bar 11 are provided at both ends with external screw thread 111 and groove 112；Vertical pole 12 is provided with through hole with one end that cross bar 11 is connected,
The protrusion coordinated with groove 112 is provided with the inside of through hole, it is necessary to which explanation, the diameter of above-mentioned through hole are more than the straight of cross bar 11
Footpath, so as to ensure that the vertical pole 12 can be installed on cross bar 11.In use, a nut is first installed on cross bar 11 now,
Then the protrusion of vertical pole 12 is stuck in the groove 112 of cross bar 11, one nut finally is installed in the end of cross bar 11, with facility
Vertical pole 12 is fixed on a suitable position with two nuts, and prevents vertical pole 12 around cross bar 11 by raised and groove 112
Rotation, so when needing the distance between regulated quantity vertical pole 12, need to only pass through the position of two nuts of adjusting, simple side
Just.
It should be noted that the cross bar 11 of the railway freight-car leading block of the utility model and the junction of vertical pole 12 are differed
Surely it is arranged to connect by raised, groove 112 and screw thread, nut, it can also be the connection of other forms, such as can be with
Selection uses pin connection, and can also be designed as cross bar 11 can be with the Telescopic rod structure of linear regulation length, as long as disclosure satisfy that
Distance between vertical pole 12 can be adjusted.
In the further embodiment of the utility model, wheel carrier 1 includes a cross bar 11 and two vertical poles 12, every vertical pole
