Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, the utility model vehicle mechanical lock locking mechanism, comprises fixed bearing 1, housing 6, left and right locking plate 5,4, operating grip 2, left and right return torsion spring 7,3, snap close bearing 11, snap close 12; Fixed bearing 1 is provided with housing 6, and housing 6 is provided with snap close guide groove 21, and the left and right sides of snap close guide groove 21 is respectively equipped with left and right locking plate 5,4, and the top of left locking plate 5 is provided with left return torsion spring 7, and the top of right locking plate 4 is provided with right return torsion spring 3; Left and right locking plate 5,4 is fixed on fixed bearing 1 together with left and right return torsion spring 7,3 and housing 6; The confined planes 20 that described right locking plate 4 is provided with limiting tooth 18 and fits with housing 6, left locking plate 5 is provided with the spacing breach 17 that can be meshed with above-mentioned limiting tooth 18 and the lock groove 16 for matching with snap close 12; Snap close 12 is fixed on snap close bearing 11, right locking plate 4 and operating grip 2 one each other, and operating grip 2 tops are provided with push rod 22, and the other end of push rod 22 is fixed on the front of door, window or hood.
The use procedure of this lockable mechanism is as follows: when door, window or hood are closed, first snap close 12 enters the snap close guide groove 21 of housing 6, lock groove 16 sides along left locking plate 5 move upward, and drive left locking plate 5 to rotate counterclockwise, due to the effect of left locking torsion spring 7, left locking plate 5 has the trend of clockwise return all the time, in the time that the limiting tooth 18 of right locking plate 4 embeds the spacing breach 17 of left locking plate, snap close 12 positions are fixed, now in one-level lockup state, as shown in Figure 3.When snap close 12 continues to move upward, promote left locking plate 5 and continue to rotate counterclockwise to extreme position, now the position of left and right locking plate 5,4 is all locked, fixes and realizes locking thereby snap close 12 snaps in the interior position of lock groove 16, in secondary lockup state, as shown in Fig. 2 dotted portion.When housing 6 can prevent that door, window or hood from closing, the excessive or right locking plate 4 of left locking plate 5 amounts of spin produces unnecessary motion, carries out spacing to left and right locking plate 5,4.
Operating grip top is provided with push rod 22, while needing release, manually promoting push rod 22 moves downward, and drive right locking plate 4 certain angle that turns clockwise, until the limiting tooth 18 of right locking plate 4 separates with left locking plate, under the effect of left return torsion spring 7, left locking plate 5 clockwise rotates return, drive snap close 12 to move downward and depart from lock groove 16, thereby realize the release of lockable mechanism, as shown in Fig. 2 solid line part.Now, right locking plate 4 also rotates counterclockwise return under the effect of right return torsion spring 3.
Further, housing 6 is provided with torsion spring guide groove 19, left locking plate 5 is provided with torsion spring fixing hole 15, one end of left return torsion spring 7 is hooked in above-mentioned torsion spring fixing hole 15, the other end is supported in above-mentioned torsion spring guide groove 19, one end of right return torsion spring 3 is hooked in the groove of limiting tooth 18 sides, and the other end is supported in above-mentioned torsion spring guide groove 19.For preventing left and right return torsion spring play upper and lower 7,3, therefore be provided with a torsion spring guide groove 19 in housing 6 inner sides, under the restriction of torsion spring guide groove 19, left and right return torsion spring 7,3 can the steady slippage of along continuous straight runs.
Further, left and right locking plate 5,4 is fixed on fixed bearing 1 together with housing 6 by compress gasket 8, hold-down nut 9 and set bolt 10.
Further, snap close 12 is fixed on snap close bearing 11 by nut 13 and pad 14.
