The specific embodiment

For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present invention and beneficial effect more, the applicant general elaborates in the mode of embodiment below, but all be not restriction to the present invention program to the description of embodiment, any according to the present invention's design done only for pro forma but not substantial equivalent transformation all should be considered as technical scheme category of the present invention.

See also Fig. 1, as wing opening type carriage undoubtedly have one be placed in the envelope 1 on the chassis 11 and be arranged on the side door 2(that the chamber, railway carriage or compartment 12 of envelope 1 is opened or closed of being used for of the length direction of envelope 1 specifically can be referring to Fig. 2 and Fig. 3).Provided the lock hook seat 3 as the structural system of side door Manual locking mechanism of the present invention among Fig. 1, under the use state, this lock hook seat 3 usefulness one group of lock hook seat hold-down screw 321(Fig. 2 and Fig. 3 show) fixing corresponding to the position that is preset in the screw hole 32 on the lock hook seat 3 and aforesaid chassis 11.A side of 11 is extended with pair of side plates 31 with parallel state back to the chassis at lock hook seat 3, respectively offers the connecting hole 311 of manually trying to stop people from fighting each other on this pair of side plates 31 and in the position to correspond to each other.

Continue to see Fig. 1, provided a latch hook 4, this latch hook 4 consists of a pair of latch hook arm 41 that corresponds to each other, and by the shape shown in the figure as can be known, the shape of a pair of latch hook arm 41 exactly likes banana-shaped, namely is crescent.One end of each latch hook arm 41 namely is connected with pair of side plates 31 pivots by latch hook arm bearing pin 413 towards an end of side plate 31, the other end of a pair of latch hook arm 41 namely deviates from an end of side plate 31 as free end, and common formation has a latch hook head 411, this latch hook head 411 obviously is that and snap close head 21 that be formed in side door 2 belows signal by Fig. 2 and Fig. 3 are implemented locking or discharged, and respectively offers a hitch frame pivot axis hole 414 at the middle part of a pair of latch hook arm 41 and in the position of correspondence.Again, outward a latch hook arm 41 is fixed with a lock and hangs pin 412 under a pair of latch hook arm 41 use states, and the end of hanging pin 412 at this lock expands and is provided with one and hangs pin and expand and establish bead 4121.

Manually try to stop people from fighting each other 5 preferably but not the structure that definitely is limited to is as follows: comprise first, the second torque arm 51,52, torque arm pivotal axis 53, hand lever axle 54 and hitch frame connecting axle 55, one end of torque arm pivotal axis 53 is that the left end of location status shown in Figure 1 is set in the wherein one piece of side plate 31(diagram left side in the aforesaid pair of side plates 31) on the connecting hole 311 of manually trying to stop people from fighting each other on, and lean out the connecting hole 311 of manually trying to stop people from fighting each other, and the other end of torque arm pivotal axis 53 is set in another piece side plate 31(diagram right side in the pair of side plates 31) on the connecting hole 311 of manually trying to stop people from fighting each other on, and lean out equally the connecting hole 311 of manually trying to stop people from fighting each other.First, second torque arm 51,52 parallel, and corresponding to the outside of latch hook arm 41, that is to say that a pair of latch hook arm 41 is between first, second torque arm 51,52.Offer one first mating holes 511 in the first torque arm 51 towards an end of torque arm pivotal axis 53, this first mating holes 511 is nested with the aforementioned end (left end) at torque arm pivotal axis 53, the second torque arm 52 offers one second mating holes 521 towards an end of torque arm pivotal axis 53, and this second mating holes 521 is nested with the aforementioned other end (right-hand member) at torque arm pivotal axis 53.As preferred scheme, can respectively add block piece at the two ends of torque arm pivotal axis 53, to first, second torque arm 51,52 spacing, prevent that first, second torque arm 51,52 from escaping in torque arm pivotal axis 53 by block piece.Block piece both can use jump ring, also can select and use cottor pin, and present embodiment is selected the former, namely adopts jump ring.One end of hand lever axle 54 and the other end of the first torque arm 51 are fixed, and the other end of the other end of hand lever axle 54 and the second torque arm 52 is fixed.Hitch frame connecting axle 55 is between torque arm pivotal axis 53 and hand lever axle 54, and an end and the first torque arm 51 are fixing, and the other end is fixed with the second torque arm 52.Aforesaid hand lever axle 54 serves as in fact the effect of handle.

Hitch frame 6 preferably but not the structure that definitely is limited to is as follows: comprise the traction arm axle 61, the first draft arm 62 and the second draft arm 63, one end of traction arm axle 61 is that the left end of location status shown in Figure 1 is bearing in one of them latch hook arm 41(diagram left side in the aforementioned a pair of latch hook arm 41 rotationally) on hitch frame pivot axis hole 414 in, and the other end is bearing in one of another latch hook arm 41(diagram right side in a pair of latch hook arm 41 rotationally) on hitch frame pivot axis hole 414 in.It is parallel that first, second draft arm 62,63 keeps each other, and this first, second draft arm 62, an end of 63 all be nested with on traction arm axle 61, and the other end all is nested with on aforesaid hitch frame connecting axle 55.By shown in Figure 1, the first draft arm 62 and the second draft arm 63 are all between first, second torque arm 51,52.Because the first torque arm 51 outward under the use state, therefore an end of the lock 7 of the present invention's recommendation is arranged on the first torque arm 51 back to an end of the second torque arm 52 rotationally by insurance stud shaft 72, the other end of lock 7 constitutes free end, and consists of at lock 7 and to have one to hang with aforesaid lock and to sell 412 stopper slots that match 71.

Please specifically referring to Fig. 2, when side door 2 is in the state that the chamber, railway carriage or compartment 12 of envelope 1 is sealed, grip 5 the hand lever axle 54 of manually trying to stop people from fighting each other by the operator, 5 drag the state shown in Figure 2 that causes to the right until will manually try to stop people from fighting each other, under this state, first of hitch frame 6, the second draft arm 62,63 be in manually try to stop people from fighting each other 5 first, the second torque arm 51,52 coincide, namely first, the second draft arm 62,63 integral body are corresponding to first, the second torque arm 51, between 52, more particularly, torque arm pivotal axis 53, traction arm axle 61 and hitch frame connecting axle 55 are in a straight line, and be namely in the same plane.Therefore the latch hook head 411 of latch hook arm 41 just matches with the snap close head 21 of side door 2, to 21 lockings of snap close head, and lock 7 is hung lock hanging on the pin 412, namely makes stopper slot 71 and lock hang pin 412 and cooperates.

Ask for an interview Fig. 3, in the time side door 2 will being opened, the locking that latch hook head 411 is broken away from snap close head 21, operating process is opposite with the operating process of Fig. 2, specifically first lock 7 is opened by the operator, the control that disengaging is hung pin 412 to lock is dragged hand lever axle 54 and to be drawn, until drags the state shown in Figure 3 that causes towards a left side
