Accompanying drawing explanation
Accompanying drawing 1 is track connector section-drawing of the present utility model.
Detailed description of the invention
See Fig. 1, shown in, adaptor union comprises the first noumenon 1 and the second body 2, and the first noumenon 1 has protruding edge, and edge has groove, and the second body 2 has hooked projection, and projection can fasten in groove.After the first noumenon 1 and the second body 2 fasten, form rectangle spatial accommodation.Groove center position on the first noumenon 1 arranges anchor shaft.
First hook portion 8 is lower position hook portion, and the second hook portion 10 is high position hook portion.First hook portion 8 has centre hole portion 3, and centre hole portion 3 is set in anchor shaft, and the first hook portion 8 can rotate to an angle around anchor shaft.First hook portion 8 has sunk part, and centre hole portion 3 raises up relative to sunk part, and sunk part holds after the second hook portion 10, first hook portion 7 and the second hook portion 10 coordinate, and forms a more smooth plane.The bottom of the second hook portion 10 is ring part 4, and ring part 4 has centre hole, and the internal diameter of this centre hole is set in centre hole portion 3 slightly larger than the ring part 4 of centre hole portion 3, second hook portion 10.Second hook portion 10 can even rotate to an angle around anchor shaft.
Two coil springs 7 are set in centre hole portion 3 and ring part 4 respectively, and each coil spring 7 has two ends, and wherein, a helical spring end is that straight line extends, and another end is inserted into the first hook portion 8.Another position, helical spring end straight line extends, and another end is inserted into the helical spring straight line extended end portion of the second hook portion 10. two and stretches out rectangle spatial accommodation, is stopped by the raised brim of the first noumenon.When the first hook portion 8 and the second hook portion 10 rotate around anchor shaft, two springs play barrier effect, get back to initial position for making the first hook portion 8 and the second hook portion 10.
The correspondence position that circular protrusions 6 is arranged on the first hook portion 8 second hook portion 10 has the through groove of arc, and circular protrusions 6 is contained in the through groove of arc.Circular protrusions 6 can only be moved in the space that the through groove of arc limits, and is defined the limit of the movement angle of the first hook portion 8 and the second hook portion 10 by circular protrusions 6.The sense of motion of the first hook portion 8 and the second hook portion 10 is counter motion, that is, the first hook portion 8 and people's hook portion 10 can open and step up.
The hook top of the second hook portion 10 has thickening protruding 10, for more firmly engaging when fastening.
Arch pin 11 is the arch pin rod of an approximate circular arc.One end of arch pin 11 is fixed on the middle part 12 of the first hook portion 10, and people with holding arch pin, can pull the first hook portion 8.Because arch pin has certain length, conveniently hold, the larger arm of force is provided, more conveniently pull the first hook portion 8.
Hooked projection 13, is arranged on the second hook portion 10 lateral surface, for strengthening the mechanical strength of the second hook portion 10.
First hook portion 8 and the second hook portion 10 define a spatial accommodation after fastening, the shape in space and the shape of the second hook portion 10 close, for holding the second hook portion of another rail vehicle couplers; Can be formed and firmly connect.
During use, need two track connector to use simultaneously, connect different car bodies respectively.Second hook portion 10 of one of them track connector extrudes the first hook portion 8 of another track connector, first hook portion 8 is rotated a bit laterally, second hook portion 10 of two track connector fastens mutually, simultaneously in the effect of coil spring return, first hook portion 8 returns to initial position, reaches adaptor union and connects effect.When needing to dismantle the track connector linked together, pulling arch bar, arch bar is opened, rail vehicle couplers separately, reaches the object of dismounting simultaneously.
