The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The utility model relates to a lock body structure of a file cabinet, which comprises a bottom box 100, a motor 200, a movable seat 400, a mechanical lock 500 and a control panel 600.

As shown in fig. 1, the bottom case 100 has a rectangular parallelepiped box-like structure. The inside of the bottom case 100 is provided with a locking tongue 110. In this embodiment, the lock tongue 110 has two cylindrical lock columns, which are parallel to each other and are vertically distributed, and the lock tongue 110 horizontally moves left and right on the bottom case 100 with the direction of illustration, and the lock columns move inside and outside the bottom case 100 along with the expansion and contraction of the lock tongue 110. The movable base 400 is slidably mounted in the base case 100, and the movable base 400 can be horizontally moved with respect to the base case 100. The motor 200 and the speed gear set 300 are mounted on the traveling block 400. As shown in fig. 1, 2 and 3, the driving end of the motor 200 is engaged with the speed change gear set 300. A first eccentric pushrod 310 is provided at the rear end of the speed gear set 300. The first eccentric push rod 310 performs eccentric rotation. The mobile station 400 is normally at a relatively stationary position on the base 100. First eccentric pushrod 310 is slidably coupled to locking bolt 110. The motor 200 can rotate forward and backward, and the gear set 300 drives the first eccentric push rod 310 to rotate forward or backward, so as to push the lock tongue 110 to translate relative to the bottom box 100. The speed change gear set 300 can accelerate the rotation of the motor 200 to accelerate the eccentric rotation speed of the first eccentric rotation shaft. The mechanical lock 500 is installed in the bottom case 100, and the mechanical lock 500 is located near the right end of the moving seat 400. The mechanical lock 500 is provided with a second eccentric push rod 510, and after the mechanical lock 500 is inserted by a corresponding matched key, the key is turned to drive the second eccentric push rod 510 to eccentrically rotate. The second eccentric push rod 510 is slidably coupled to the movable base 400. When the second eccentric push rod 510 performs eccentric rotation, the moving seat 400 can be driven to perform left-right translation, so that the first eccentric push rod 310 moves along with the moving seat 400, and further drives the lock tongue 110 to perform left-right translation. The control board 600 is electrically connected to the motor 200 through a wire. In normal use, motor 200 is controlled to rotate in a forward and reverse direction by control board 600, and lock tongue 110 is driven to move to perform unlocking or locking operation. If the control board 600 or the motor 200 fails and cannot be started, or if there is no electricity, a key can be inserted into the mechanical lock 500, and the second eccentric push rod 510 is rotated to drive the moving seat 400, the motor 200, the gear-shifting set 300, and the first eccentric push rod 310 to translate, so as to drive the lock tongue 110 to move for unlocking or locking. The whole structure is simple, and the volume is small; under the action of the speed change gear set 300, the lock tongue 110 can translate rapidly; the mechanical lock 500 is used as a spare lock member, and is safe and reliable.

In some embodiments of the present utility model, as shown in fig. 2, lock tongue 110 includes a connection part 120, and a left side of connection part 120 is provided with a lock cylinder that moves telescopically inside and outside of bottom case 100. The connecting portion 120 is provided with a first sliding groove 121, and an extending direction of the first sliding groove 121 is perpendicular to a translation direction of the lock tongue 110. In this embodiment, the front and rear sides of the bottom case 100 are large planes, and the latch tongue 110 translates left and right in a direction parallel to the large plane of the bottom case 100. The first sliding groove 121 extends in the front-rear direction, and is perpendicular to the large plane of the bottom case 100. First eccentric push rod 310 extends into first sliding groove 121, and first eccentric push rod 310 rotates eccentrically clockwise or counterclockwise as viewed from the top as shown in fig. 2, which corresponds to rotation in the translational direction of lock tongue 110.

In some embodiments of the present utility model, a second sliding groove 410 is formed on the moving seat 400, and an extending direction of the second sliding groove 410 is perpendicular to a translation direction of the locking bolt 110. Locking bolt 110 translates in a left-right direction, second sliding groove 410 extends in an up-down direction, and the extending direction of second sliding groove 410 is parallel to the large plane of lock bottom case 100. The second eccentric push rod 510 is inserted into the second sliding groove 410 such that the second eccentric push rod 510 is eccentrically rotated in a clockwise or counterclockwise direction as viewed from the front in the direction shown in fig. 4.

In some embodiments of the present utility model, as shown in FIG. 3, the speed gear set 300 includes a number of compound gears 320. Each of the compound gears 320 in turn meshes with the transmission. Each of the combination gears 320 includes a large gear 321 and a small gear 322 coaxially disposed. The tooth diameter of the large gear 321 is larger than that of the small gear 322. In the transmission direction, the pinion 322 of the previous combination gear 320 is engaged with the bull gear 321 of the next combination gear 320. The large gear 321 on the first combined gear 320 is meshed with the driving shaft of the motor 200. The first eccentric push rod 310 is connected to the last combination gear 320, and the center of the first eccentric push rod 310 is coaxially disposed with the combination gear 320. The first eccentric push rod 310 is accelerated by the linkage of the plurality of combination gears 320.

In some embodiments of the present utility model, as shown in fig. 4, a first travel switch 710 and a second travel switch 720 are mounted on the bottom case 100. First travel switch 710 and second travel switch 720 are located in the translational path of locking bolt 110, respectively. The first and second travel switches 710 and 720 are electrically connected to the control board 600 through wires. In this embodiment, the first travel switch 710 is used as a travel limit trigger mechanism when the lock tongue 110 moves leftwards, and the second travel switch 720 is used as a travel limit trigger mechanism when the lock tongue 110 moves rightwards. When the latch bolt 110 translates left and right, the first travel switch 710 or the second travel switch 720 is touched, and the first travel switch 710 and the second travel switch 720 feed back signals to the control board 600, so that the control board 600 controls the stopping of the motor 200.

In some embodiments of the present utility model, as shown in fig. 5, a cover plate 130 is provided on the front side of the bottom case 100. The cover 130 is used for mounting the bottom case 100 to a cabinet door of a file cabinet. The cover plate 130 is provided with a plurality of plug holes 131, and the plug holes 131 can be matched with the convex columns on the cabinet door for installation or matched with the front-back lock opposite-pull installation and other installation modes.
