DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment.
As shown in FIG. 2, a hinged female part 2 and a male part 3 are disposed on the rear end of a metal fitting body 1 made of a cylindrical tube at axes 45.degree. The mounting plate 5 is integrally bonded to the back surface of the seat plate 4 at the center of attachment of the metal fitting body 1, and a short link 6 is swingably connected to the mounting ring 5. A screw shaft 7 is swingably joined to the rear end 6, and a friction plate 8 is adhered to the lower inner peripheral surface of the bracket main body 1 over the entire length thereof. A guide seat 9 having a required downward slope is provided radially around the center plane and the upper vertical center plane, and a long hole 10 having a required width and a required length is provided at the front top part. A long bearing seat 11 is erected to the left on the top surface of the top, and a short bearing seat 12 is erected to the right, and a support shaft 13 is supported on both bearing seats 11 and 12. Shaft rod 1 of the handle 14 to the support shaft 13
5 at the shaft attachment part, with the required gap
The torsion coil spring 16 is axially mounted, one end of the torsion coil spring 16 is engaged with the shaft rod 15, and the other end of the torsion coil spring 16 moves up and down on the upper inner surface of the fitting body 1.
7 is engaged with a receiving seat 18 at the center of the upper surface, and the pressing body 17 is formed with the same radius of curvature as the shut-off rod 19 having the reference diameter. and engaged with a lower end rotatably each parallel linkage 21 is in seat 18 that is set, and engaged the top end of the parallel link 21 to the bearing seat 11 of the left than the long hole 10, the rear of the slot 10 As shown in FIG. 3, an engaging seat 23 having an inverted concave groove 22 is formed on the top surface.
And a magnet 2 is provided on the upper surface of the seat 23.
4 and a cover 25 covering the entire long hole 10 including the bearing seats 11 and 12 from the engagement seat 23 on the top surface.
Is hingedly attached to a hinge 26, a latch 27 is attached to a side opening end of the cover 25, and the latch 27 is attached to a stopper 28 swingably attached to the outer peripheral surface of the fitting body 1. Consisting of

As shown in FIG. 4, the movable metal member b has a female part 30 and a male part 31 of a hinge disposed on a seat plate 29 of a fixed metal part c. The female part 2 and the female part 2 are arranged in a fitting manner, and the shaft 32 is inserted through the male part 31 and the female part 2 on the left side and is prevented from coming off with a nut 33, and a hinge is formed to join the two swingably. Further, the screw shaft 7, which penetrates through the seat plate 29 of the fixing metal c and projects into the metal fitting body 34, has a coil spring 35 whose tip is seated on the seat plate 29.
And a washer 36 which is loosely fitted to the screw shaft 7 is brought into contact with the rear end thereof, and the washer 36 is tightened up with a nut 37 screwed to the screw shaft 7 to compress the coil spring 35 as required, thereby fixing the fixing bracket. The movable metal member b is pressed and joined to the member c with a predetermined mounting load.

Therefore, in use, the fixing member c is fixed to a column (not shown) standing upright on the side of the level crossing, and is movable from outside the level crossing via the blocking rod 19 in use. The direction of the hinge is selected and used so that the movable bracket b operates from the inside to the outside without opening the bracket b.

In the unlikely event that the breaking rod 19 is broken, the worker rushes to the work site, and
, The cover 25 is raised, and the shaft rod 15 of the handle 14 is pushed down to a position where the shaft rod 15 is disengaged from the reverse concave groove 22 of the engagement seat 23.
In this state , the shaft 15 is twisted toward the opening side of the seat 23,
Release the pressure on the handle 14 at the position where the engagement seat 23 crosses.
When released , the pressing state of the pressing body 17 by the torsion coil spring 16 is released, so that the blocking rod 19 is easily pulled out from the fitting main body 1 with one hand, and when the new blocking rod 19 is inserted into the fitting main body 1, the release rod 19 is released. The entry end is guided by the slope of the guide seat 9 and is pushed downward to position the entry end,
With the shaft 15 of the handle 14 facing the opening side of the engagement seat 23
Twisting at a position not interfering with the engagement seat 23, Han in this state
The dollar 14 is pushed down , and the shaft 15 is returned to the reverse concave groove 22 side .
When the handle 14 is released, the shaft 15 is inverted
Was engaged, the pressing member 17 presses the shut-off rod 19 with a predetermined load of the torsion coil spring 16, the blocking rod 19 is sandwiched between the lower inner peripheral surface of the pressing member 17 and the fitting body 1, pressing pressure body 17 of
The friction plate 20 integral with the inner surface and the friction plate 8 lined with the inner peripheral surface described below provide a strong stopper and prevent damage. After the blocking rod 19 is fixed, the cover 25 is covered, the latch 27 is engaged with the stopper 28, and locked, thereby preventing mischief and protecting the pressing means from rain, wind, snow, and the like.

[0011]

As described above, according to the railroad crossing breaker rod breaker a of the present invention, in the work of replacing the breaker rod, one worker does not need any skill or tool, and the one-touch operation of the breaker rod is possible. Since it can be attached and detached, labor is saved and the working time is shortened.
