J 9 200842070 The shielding operation of the present invention is performed by manually turning the operation portion 4 12 of the third figure to rotate the covering portion 4 2 of the shielding plate 4 in the direction of the shielding key opening 6 2 as the shielding plate. 4 During the rotation, the latch 421 on the outer side of the cover portion 4 2 will retreat against the broadcast portion 512 of the lock member 5 and pass through the striker 512, and then the lock member is biased by the spring force of the spring 52. 5 Move forward to reset, the part 5 1 2 of the locking member 5 will form a lock on the rear end of the stencil end 4 2 1 ', as shown by the red riding, when the ship board 4 is positioned by the sensitive part 5, the covering part of the shielding board 4 2 Recording the keyhole 6 2 above, (4) can prevent the illegal user from inserting the keyhole 6 2 with an improper tool to open the lock. Regarding the operation implementation of the open mask of the present invention, please refer to the fourth and sixth figures, the signal is sent within the permitted range by using the corresponding signal generator 8 i, and can be driven after the receiver 8 2 receives the signal. The electromagnetic switch 30 of the unlocking device 3 attracts the movable arm 3 to be retracted. After the movable arm 3丄 and the locking member 5 are retracted, as shown in the seventh embodiment, the locking end 4 2 1 of the shielding plate 4 is The latch of the holding portion 5 1 2 is released, and the state of the shield plate 4 is pushed back by the elastic force of the spring 4 3 to release the keyhole 6 2 for key insertion. Referring to the eighth embodiment, there is shown a second embodiment of the shielding device constructed according to the present invention. In the present embodiment, the same or equivalent components as those described in the first embodiment will be denoted by corresponding reference numerals, and the detailed description will be omitted. Wherein, the available signal connection UI8 2 (4) actuation solution 3 includes a motor 3 3 in the remaining box 200842070 3 4 and a movable arm 31 which can be controlled by the motor, in the embodiment 'the motor A first gear 3 31 is mounted on the output shaft of the 3 3 , and the first gear 3 31 is meshed with a second gear 35 1 1 disposed at a screw end 5 5, and the rear end of the movable arm 31 and the rear end of the movable arm 31 The outer end of the screw 35 is coupled. As described above, the front end of the movable arm 31 is coupled to the engaging arm of the locking member. Therefore, the advancement or retraction of the screw 35 will drive the arm and the locking. Piece 5 advances or retreats. Therefore, after the corresponding signal generator 8 1 is used to signal within the allowable range, the motor 3 3 of the unlocking device 3 can drive the movable arm 31 and the locking member 5 to retreat, thereby releasing the locking member 5 for shielding. The latch of the board 4 achieves the effect of controlling the shutter 4 to open the keyhole 6 2 by means of a signal generator. The shielding device constructed according to the present invention not only has a simple structure, but also can shield and release the shielding plate without using the key, which is convenient and reliable in use; moreover, if the shielding plate 4 is moved to the closed position but not When locking, the shielding plate can be restored to the open position state by the elastic force of the spring 43, so that the user does not cause misidentification whether the shielding plate 4 is actually closed. The foregoing is a description of the construction of the preferred embodiment of the present invention. The design spirit of the present invention can be variously modified or modified. For example, the binding arm of the locking member and the movable arm of the unlocking device are not limited to the use of the sleeve. Connections, other conventional bonding techniques can also be used. Therefore, those who are familiar with this skill can make obvious substitutions and modifications, and the supplements are in the special area around the day. 200842070 [Simplified illustration of the drawings] The first drawing is an exploded view of the first embodiment of the present invention; the f-picture is a partial transverse sectional view of the first embodiment; and the shielding plate is not shielded.
