Abstract
The utility model discloses the Foldable mechanism for rail profile measuring instrument, adopt the folding mechanism of three connecting rods, and by a custom-designed locking device, three poles are locked, ensure that the horizontal reference that rail profile is measured is reliable, and easy to carry.The utility model has the advantages that: the length after the horizontal reference bar rigidity after expansion is large, folding is short, lock can be in the rod member locking of expansion and folded state.Significantly can improve the horizontal positioning accuracy of rail profile measuring instrument.
Description
Technical field
This Foldable mechanism is used for a kind of rail profile measuring instrument of hand-held.Be generally used for railway department and research institution etc.
Background technology
In detection to left and right stock rail profile, require that can have a comparatively large rigidity, and the horizontal reference bar that can conveniently fold again, all there are problems in current various horizontal reference bars, otherwise be exactly because Rigidity horizontal positioning accuracy is not high, otherwise be exactly that length is oversize, not Portable belt.This folding mechanism, have employed the mechanism of three connecting rods, and can be locked by three poles by a custom-designed locking device, ensure that the horizontal reference that rail profile is measured is reliable, and easy to carry.
Utility model content
The purpose of this utility model be to provide have compared with large rigidity and portable a kind of horizontal reference bar for rail profile measuring instrument.This horizontal reference bar adopts the folding mechanism of three connecting rods, and is locked by three poles by a custom-designed locking device, ensure that the horizontal reference that rail profile is measured is reliable, and easy to carry.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is:
For a Foldable mechanism for rail profile measuring instrument, comprise at least three connecting rods, and connect the hinge of connecting rod, connecting rod can be launched or fold, it is characterized in that: on described hinge, be also provided with locking mechanism.
Wherein, described hinge is made up of left and right, and two pin-and-holes are arranged at top, and described pin-and-hole is for inserting locking mechanism.Particularly, described locking mechanism is inserted in hinge by two alignment pins, is connected with Synchronous lifting bar with alignment pin, promotes bucket and lifting handle.
Foldable mechanism for rail profile measuring instrument is installed on a rail, and two ends are fixed by angle, angle and measured rail is reclined, to reach the positioning function of this Foldable mechanism.
Rail profile gage outfit is arranged on the connecting rod of wherein one end.
For the Foldable mechanism of rail profile measuring instrument, be the assembly of devices of whole horizontal reference bar, left side is connected with the gage outfit of rail profile measuring instrument, tested rail be placed in below, positioning datum with the end face common tangent of left and right rail for positioning datum.
Compared with prior art, the utility model has the advantages that: the length after the horizontal reference bar rigidity after expansion is large, folding is short, lock can be in the rod member locking of expansion and folded state.Significantly can also improve the horizontal positioning accuracy of rail profile measuring instrument.

Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model is further described.
Refer to shown in Fig. 1, Fig. 2, for the Foldable mechanism of rail profile measuring instrument, three connecting rods are first connecting rod 2, second connecting rod 4, third connecting rod 6 respectively, and by two chain connections, the top of two hinges is provided with the first locking mechanism 3 and the second locking mechanism 5.Rail profile gage outfit 1 is arranged on first connecting rod 2, and third connecting rod has installed collets 86 times.Left side located lateral pin 9 and right side located lateral pin 7 are arranged on first connecting rod 2 and third connecting rod 6 times respectively, recline mutually with the medial surface of left side rail 12 and right side rail 13.
Wherein as shown in Figure 3, Figure 4, each hinge is made up of left 10 and right 11, and two pin-and-holes are arranged at top.Be used for inserting alignment pin left 14 and the alignment pin right side 20 of locking mechanism.First locking mechanism 3 and the second locking mechanism 5 comprise the Synchronous lifting bar 19 be connected with alignment pin right 20 with alignment pin left 14, promote bucket 18, promote screw 15, lifting handle 16 and lock housing 17.
