Travelling nut
Technical field
The utility model belongs to nut, is specifically related to a kind of travelling nut.
Background technique
Nut is widely used in the connection between various devices, and attachment screw uses, and after screw passed all device mounting holes, suit packing ring on its termination screw rod oppositely was screwed into nut, and nut is tight against on the device outer wall again, plays the effect of immobilising device.
Nut and screw are installed in the device both sides, usually obstacle causes the assemblage gap of nut little more for a long time around the device, and its shortcoming is: nut is difficult in narrow and small assemblage gap and the accurate contraposition in device mounting hole, the screw rod of screw termination can not be screwed into nut, and nut and screw are installed difficulty.
The model utility content
The purpose of this utility model provides a kind of nut, can make the accurate contraposition of nut and device mounting hole in narrow and small assemblage gap, is convenient to nut and screw fit and installs.
The purpose of this utility model can reach by the following technical programs, and promptly a kind of travelling nut comprises nut, and its key is: the end face of described nut is connected with backing plate, and this backing plate has through hole and communicates with the tapped through hole of described nut.
Backing plate both can replace packing ring, can stretch out from assemblage gap again, was convenient to operator's clamping, can make the accurate contraposition of nut and device mounting hole.
Described backing plate and nut welding are fixing.
On described backing plate, be welded with journal stirrup.
Journal stirrup can enlarge the clamping end face of backing plate, is convenient to adjusting nut, makes more convenient operation.
Remarkable result of the present utility model is: can be convenient to the accurate contraposition of nut and device mounting hole in narrow and small assemblage gap, install flexibly, simultaneously, reduce the operation of suit packing ring, benefit nut and screw fit and install and regulate.

Fig. 2 is a side view of the present utility model;
To be the utility model be installed in structural representation on the four-wheel beach buggy vehicle frame with welded tube to Fig. 3.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2: a kind of travelling nut, comprise nut 1, the end face of described nut 1 is connected with backing plate 2, and this backing plate 2 has through hole and communicates with the tapped through hole of described nut 1.
Backing plate 2 both can replace packing ring, can extend outside the assemblage gap again, was convenient to operator's clamping, can make the accurate contraposition of nut and device mounting hole.
Described backing plate 2 is fixing with nut 1 welding.
On described backing plate 2, be welded with journal stirrup 3.
Journal stirrup 3 can enlarge the clamping end face of backing plate 2, is convenient to adjusting nut, makes more convenient operation
Its working principle is as follows:
As shown in Figure 3: when on four-wheel beach buggy vehicle frame 4, fixedly mounting welded tube 5, the mounting hole of welded tube 5 journal stirrup 5a communicates with the mounting hole of vehicle frame 4, h is too small because of assemblage gap, clamp the backing plate 2 or the journal stirrup 3 of travelling nut with assistant tool, nut 1 is stretched into assemblage gap h, nut 1 is communicated with the accurate contraposition in device mounting hole of journal stirrup 5a, vehicle frame 4, mounting hole from vehicle frame 4 oppositely inserts screw and rotation again, screw end is threaded with nut 1, realizes fixedlying connected between vehicle frame 4 and welded tube 5 devices.
