Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The first embodiment is as follows:

the structure of the electric piston tap lock of the present embodiment, as shown in fig. 1 to 8, includes: the device comprises a fixed frame 1, a motor 2, a driving wheel 3, a sliding block 4, a first pressure spring 5, a second pressure spring 6, a sliding shaft 7 and a lock tongue 8.

The fixed frame 1 is provided with a fixed bin 11 for mounting each part; the motor 2, the transmission wheel 3, the slide block 4, the first pressure spring 5, the second pressure spring 6 and the sliding shaft 7 are all arranged in the fixed bin 11.

The fixing frame 1 is provided with a fixing mechanism 14, and the motor 2 is fixed on the fixing mechanism 14.

The bolt 8 is fixed on one end of the sliding shaft 7, and the other end of the sliding shaft 7 is provided with a retaining ring 71; the sliding block 4, the first pressure spring 5 and the second pressure spring 6 are all sleeved on the sliding shaft 7, and the sliding block 4 is located between the first pressure spring 5 and the second pressure spring 6; the first pressure spring 5 props against the lock tongue 8, and the second pressure spring 6 props against the retainer ring 71; when the sliding block 4 extrudes the first pressure spring 5, the first pressure spring 5 pushes the bolt 8 to eject from the fixed bin 11 under the action of the elastic force of the first pressure spring 5; when the sliding block 4 extrudes the second pressure spring 6, the second pressure spring 6 pushes the retainer ring 71, so that the sliding shaft 7 moves reversely, and the bolt 8 is driven to be folded into the fixed bin 11.

A worm 21 is arranged on a front output shaft of the motor 2, and a rack 41 is arranged on the sliding block 4; the worm 21 is meshed with the transmission wheel 3, the transmission wheel 3 is meshed with the rack 41, the motor 2 drives the worm 21 to rotate, the worm 21 drives the transmission wheel 3 to rotate, the transmission wheel 3 drives the rack 41 to move, and the rack 41 is fixed with the sliding block 4 into a whole, so that the sliding block 4 moves on the sliding shaft 7 along with the rack 41.

The fixing frame 1 is provided with a cover plate 13, the cover plate 13 is covered after the parts are installed, the fixing bin 11 is in a closed state, and the parts are closed in the fixing bin 11, so that the parts can be effectively prevented from being corroded by dust, and the lubricating grease can be stored.

The locking function can be realized by mounting the faucet lock of the present embodiment on the frame fixing lever 18.

The locking process of the faucet lock of the embodiment is as follows: the motor 2 drives the worm 21 to rotate, the worm 21 drives the driving wheel 3 to rotate, the driving wheel 3 drives the rack 41 to move, the sliding block 4 moves towards the first pressure spring 5 on the sliding shaft 7, the sliding block 4 extrudes the first pressure spring 5 when moving, the first pressure spring 5 pushes the sliding shaft 7 to move outwards along the extruded direction under the action of elastic force, the bolt 8 is pushed out from the fixed bin 11 by the sliding shaft 7 until the bolt 8 abuts against the movable rod 17 of the frame, after the bolt 8 abuts against the movable rod 17 of the frame, the movable rod 17 of the frame cannot rotate continuously, and the locking of the faucet lock is completed.

The unlocking process of the locked faucet lock comprises the following steps: the motor 2 drives the worm 21 to rotate reversely, the worm 21 drives the driving wheel 3 to rotate reversely, the driving wheel 3 drives the rack 41 to move reversely, the sliding block 4 moves towards the second pressure spring 6 at the sliding shaft 7, the sliding block 4 extrudes the second pressure spring 6 when moving, the second pressure spring 6 pushes the sliding shaft 7 to move inwards along the extruded direction under the action of elastic force, the bolt 8 is driven by the sliding shaft 7 to be folded towards the fixed bin 11, the bolt 8 is not propped against the movable rod 17 of the straight frame after being folded, the movable rod 17 of the frame can rotate freely without being blocked by the bolt 8, and the unlocking of the faucet lock is completed at the moment.

Example two:

the motor 2 drives the worm 21 to rotate, the worm 21 drives the transmission wheel 3 to rotate, the transmission wheel 3 drives the rack 41 to move, the working process requires that the motor 2 has larger output torque, the load on the motor 2 is heavier, and if the output of the large torque is long time, the loss of the motor 2 is accelerated, so that the output torque of the motor 2 needs to be reduced for the motor 2 to have longer service life, and a reduction gear train needs to be added in the rotating process to increase the torque.

Therefore, on the basis of the above embodiment, in order to increase the torque force, the transmission wheel 3 can be set as a first gear 31 with a small gear and a large gear, the second gear 32 with a large gear is meshed with the rack 41, the large gear is meshed with the worm 21, so that the force arm of the worm 21 is lengthened when the large gear is driven to rotate by the worm 21, and the output torque force of the worm 21 can be reduced; the pinion gear can reversely increase the output torque force to the rack 41, and at this time, although the rotation speed of the motor 2 needs to be increased, the output torque force of the motor 2 can be reduced.

Example three:

when the slider 4 slides on the sliding shaft 7, there is a position deviation, which would increase the loss of the faucet lock in the past, and in order to reduce the loss, it is necessary to reduce the position deviation of the slider 4 when the sliding shaft 7 slides, therefore on the basis of the above embodiment, in order to reduce the position deviation of the slider 4 when the sliding shaft 7 slides, a guide rail 12 may be disposed in the fixed frame 1, i.e., the fixed bin 11, the guide rail 12 is disposed parallel to the sliding shaft 7 along the sliding direction of the slider 4, the slider 4 is further sleeved on the guide rail 12, the movement track of the slider 4 is limited on the parallel line of the guide rail 12 and the sliding shaft 7, and the position deviation of the slider 4 when sliding at this time will be greatly reduced.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
