The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment one is seen accompanying drawing 5~8, and a kind of container door locking device comprises door-plate 1, vertically is rotatably connected on door lock rod 2, an end on the door-plate 1 and is welded on spanner seat 4 on the door lock rod 2, is rotatably connected on spanner 6 on the spanner seat 4 by rivet 5.Spanner seat 4 structure that is formed in one, it comprises spanner flap 40, away from the spanner seat outer wall 41 of door-plate 1, near the spanner seat inwall 42 of door-plate 1, and spanner 6 places in the spanner seat 4, and rivet 5 runs through spanner seat outer wall 41, spanner 6 and spanner seat inwall 42.Be connected with on the door-plate 1 and spanner seat 4 cooresponding spanner seat buckle closures 7, spanner seat buckle closure 7 covers in spanner seat 4 the place aheads and with rivet 5 and hides side within it, handle seat buckle closure is provided with attaching parts, door lock assembly also include be connected on the casing and with the corresponding attaching parts of attaching parts coupling, more particularly, attaching parts is a lockhole 74, and corresponding attaching parts is corresponding lockhole 44.Spanner seat buckle closure 7 includes the backplate 71 of the connecting panel 72 that flexibly connects with door-plate 1, the covering plate 70 that hides rivet 5, close door-plate 1, connecting panel 72 is captiveed joint with covering plate 70, backplate 71 is captiveed joint with connecting panel 72, and spanner seat 4 is arranged between covering plate 70 and the backplate 71.Connecting panel 72 is positioned at covering plate 70 and top, backplate 71 junctions, and connecting panel 72 is rotatably connected on the door-plate 1.Spanner seat outer wall 41 outside bending formings have bending part 43, offer corresponding lockhole 44 on the bending part 43; Covering plate 70 lower end bending formings have and bending part 43 cooresponding bending lids 73, offer and corresponding lockhole 44 cooresponding lockholes 74 on the bending lid 73, and customs closes envelope 9 and is applied on corresponding lockhole 44 and the lockhole 74.
Connecting panel 72 and door-plate 1 junction are provided with the liner plate 8 between the two, and liner plate 8 is fixed on the door-plate 1.Liner plate 8 is provided with the block 80 of restriction spanner seat buckle closure 7 rotational angles.
When operation, spanner 6 is threaded to level and is parallel to door-plate 1, screw off spanner seat buckle closure 7, be positioned at spanner seat buckle closure 7 covering plate 70 rivet 5 is kept off side within it, apply customs's pass envelope 9 at corresponding lockhole 44 and lockhole 74 places then, under the prerequisite of not damaging customs's pass envelope 9, rivet 5 is difficult to destroyed, the theftproof performance height; In addition, this structure has been saved structures such as bay cover in some conventional door-lock apparatus, bearer carrier, and structure and operation are become simply, has saved productive costs simultaneously.
Embodiment two is seen Fig. 9, and what present embodiment and embodiment one were different is that spanner seat 4 includes only spanner seat outer wall 41, spanner 6 places spanner seat outer wall 41 rears, rivet 5 runs through spanner seat outer wall 41 and spanner 6, and other structures are identical with embodiment one with principle, no longer repeats here.
Embodiment three, see Figure 10,11, different with above-mentioned embodiment one is, vertical fixing one flat plate 11 on the door-plate 1, dull and stereotyped 11 1 ends are fixed on the door-plate 1, the other end is positioned at the below of spanner seat buckle closure 7, and its below that is positioned at the lockhole 74 on the spanner seat buckle closure 7 offers the corresponding lockhole 44 with lockhole 74 couplings, applies customs's pass envelope 9 or lockset between lockhole 74 and the corresponding lockhole 44 and locks.
Spanner 6 in the said structure as shown in figure 12 since in its rotation process with above-mentioned dull and stereotyped 11 clash, so it is above-mentioned dull and stereotyped 11 to avoid that a groove 61 is set on spanner 6, make spanner 6 obtain bigger rotational angle.Other structures are identical with embodiment one with principle, no longer repeat here.
Embodiment four, see Figure 13,14 with above-mentioned be example 1 different be, locking bar external member 21 of socket on the door lock rod 2, more particularly locking bar external member 21 is dull and stereotyped, the one end is enclosed within on the door lock rod 2, the other end is positioned at the below of spanner seat buckle closure 7, and its below place that is positioned at the lockhole 74 on the spanner seat buckle closure 7 offers the corresponding lockhole 44 with lockhole 74 couplings, apply between lockhole 74 and the corresponding lockhole 44 customs close seal 9 or lockset lock.Other structures are identical with embodiment one with principle, no longer repeat here.
