The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

Extremely shown in Figure 7 such as Fig. 1, the lock gear mechanism of present embodiment comprises lock gear stand 1, gear 2 and bolt 3, lock gear stand 1 is provided with tooth bar 10, lock gear stand 1 one ends are provided with installing hole 11, installing hole is square opening, bolt 3 inserts in the installing hole 11, two lock gear stands 1 oppositely are distributed in gear 2 both sides, when key band movable lock core rotates, lock core driven gear 2 along or be rotated counterclockwise, thereby the tooth bar 10 on the lock gear stand 1 drives sliding up and down of whole lock gear stand 1 with gear 2 engagements, and when the spacing of two lock gear stands 1 was maximum, the lock gear mechanism pinned file cabinet door; When two lock gear stands 1 folded, file cabinet door was in not lock status.

Such as Fig. 2, Fig. 3, shown in Figure 4, lock gear stand 1 is comprised of upper sid strip 12, lower sid strip 13, left side bar 14, the right bar 15, left side bar 14 links to each other with lower sid strip 13 with the right bar 15, be provided with tooth bar 10 on the left side bar 14 inwardly, outward flange is provided with V-arrangement bar 16, inward flange is provided with draw-in groove 17, draw-in groove 17 clampings on the V-arrangement bar 16 after two lock gear stands 1 are assembled together on each lock gear stand 1 and another lock gear stand 1.
