Description
Technical field
The utility model relates to a kind of freight car door locking device.
Background technology
The railway carriage or compartment door of goods transport vehicle must be equipped and can close and lock the locking device of railway carriage or compartment door.The structure of existing freight car door locking device as illustrated in fig. 1 and 2, there is the base plate A1 be fixed on car body or railway carriage or compartment door, base plate A1 is fixed with the support A4 of latch hook A2 and connecting handle A3, handle A3 and support A4 is hinged, and handle A3 and draw ring A8 is hinged, and handle A3 offers chute, set within it in chute the sleeve A6 and pivot that slide, this pivot is the hinged pivot of handle A3-locking closure A5, and sleeve A 6 is fixedly connected with spring A7, and the other end of spring A7 is fixed on handle A3; The surface of draw ring A8 is provided with locking closure A5, the hole on draw ring A8 and latch hook A2 fastener.When needing locking, first by the borehole jack of draw ring on latch hook, then handle is pressed to base plate, when handle is pressed onto completely, spring is in confined state, and spring pushes against pivot, thus gives the power of a draw ring compression latch hook.When needing to unlock, handle is pulled to the direction away from base plate, until when the restoring force of spring is not enough to make draw ring and latch hook fastener, draw ring is deviate from latch hook, completes unblock.The shortcoming of this locking device is: the fatigue of spring reduces causing the self-lock force of locking device, the possibility that lorry is spread out after having locking device to loosen in traveling way, and reliable lock is not high.
Summary of the invention
There is the not good shortcoming of the reliability of self-locking to overcome existing locking device, the utility model provides a kind of freight car door locking device of self-locking good reliability.
The freight car door locking device that anticreep hooks, there is the base plate be fixed on car body or railway carriage or compartment door, base plate is fixed with the support of latch hook and connecting handle, handle and support hinged, handle and draw ring hinged, handle offers chute, set within it in chute the sleeve and pivot that slide, this pivot is the hinged pivot of handle-draw ring, and sleeve is fixedly connected with spring, and the other end of spring is fixed on handle; Hole on draw ring and latch hook fastener; It is characterized in that: the end away from latch hook of base plate offers groove, handle is hinged with the mousing-hook with groove fastener, the pivot that anticreep hook-handle is hinged is socketed with torsion spring, and one end props up handle, and the other end props up mousing-hook.
Further, mousing-hook comprises pothook and hand grip portion, the lever that it is fulcrum with anticreep hook-handle hinged place that mousing-hook is formed.
Further, the line of pothook and fulcrum and the line of hand grip portion and fulcrum are acute angle.
Further, the end bending of base plate, groove is opened in bending place, the break corner of groove.The pothook that chamfering can lead to mousing-hook departs from groove.
Further, both ends of the spring is fixed with the first back-up ring and the second back-up ring respectively, and the first back-up ring and handle are fixed, and the second back-up ring and the hinged pivot of handle-locking closure are fixed.
Further, the surface of draw ring is fixed with locking closure.
When the utility model needs locking, first by the borehole jack of draw ring on latch hook, then clutch handle and mousing-hook; handle is pressed to base plate, and when handle is pressed onto completely, spring is in confined state; spring pushes against pivot; to the power of a draw ring compression latch hook, the pothook of mousing-hook simultaneously enters in groove, unclamps hand; pothook hooks base plate; now torsion spring pushes against mousing-hook, pushes against the power of base plate to pothook one, thus on the basis of spring self-lock, increase by one mousing-hook protection.When needing to unlock, clutch handle and mousing-hook, pothook departs from base plate, is pulled by handle to the direction away from base plate, and pothook departs from groove, until when the restoring force of spring is not enough to make draw ring and latch hook fastener, draw ring is deviate from latch hook, completes unblock.
The utility model has the advantage of:
1, this locking device bending after base plate end fluting, forms the groove that can hook for mousing-hook, forms the gradient that can slide for mousing-hook, enable the pothook of mousing-hook enter and depart from groove at bending part break corner.
2, portion adds torsion spring and mousing-hook in the handle, and after the self-lock force of spring, increase by one security protection, reliable lock is high.

Detailed description of the invention
As in Figure 3-5, the freight car door locking device that anticreep hooks, have the base plate 1 be fixed on car body or railway carriage or compartment door, base plate 1 is fixed with the support 3 of latch hook 2 and connecting handle 4, handle 4 is hinged with support 3, handle 4 is hinged with draw ring 5, handle 4 offers chute, and set within it in chute the sleeve 6 and pivot that slide, and this pivot is the hinged pivot of handle 4-draw ring 5, sleeve 6 is fixedly connected with spring 7, and the other end of spring 7 is fixed on handle 4; Hole 52 on draw ring 5 and latch hook 2 fastener; The end away from latch hook 2 of base plate 1 offers groove 11, and handle 4 is hinged with the mousing-hook 8 with groove 11 fastener, the pivot that anticreep hook-handle 4 is hinged is socketed with torsion spring 9, torsion spring 9 one end props up handle 4, and the other end props up mousing-hook 8.
Mousing-hook 8 comprises pothook 81 and hand grip portion 82, the lever that it is fulcrum that mousing-hook 8 is formed with anticreep hook-handle 4 hinged place.
Pothook 81 is acute angle with the line of fulcrum and the line of hand grip portion 82 and fulcrum.
The end bending of base plate 1, groove 11 is opened in bending place, the break corner of groove 11.The pothook 81 that chamfering can lead to mousing-hook 8 departs from groove 11.
