as shown in the figures, an electric gear lock comprises a housing 1, a driving part 2 installed in the housing 1, a pushing seat 3 hinged in the housing 1 and a gear set 4 rotatably installed in the housing 1, wherein the gear set 4 comprises a gearwheel 41 and a pinion 42 which are coaxially arranged, a first elastic part 11 for connecting the pushing seat 3 and the housing 1 is arranged between the pinion 42 and the pushing seat 3, the pinion 42 and the pushing seat 3 are in contact fit, a groove 12 corresponding to the gearwheel 41 and accommodating foreign objects is formed in the housing 1, the output end of the driving part 2 is in contact fit with the end part of the pushing seat 3, and the pushing seat 3 has a first action of being pushed by the driving part 2 so as to be separated from the pinion 42 to enable the gearwheel 41 to freely rotate and a second action of being contacted with the pinion 42 again under the action of the first elastic part 11; the driving piece among this technical scheme promotes the promotion seat and swings, make the promotion seat break away from the pinion, thereby realize the unblock to the gear train, after the unblock, the gear train can the free rotation, locking lever and the contact of grafting port after the locking lever entering recess of locking seat, realize the circular telegram, when the driving piece breaks away from the promotion seat and does not give its effort, promote the seat under the pretightning force effect of first elastic component again with the pinion contact and form conflict cooperation, the gear wheel just can not rotate like this, thereby the locking lever of locking seat is pinned with the groove fit to the gear wheel, has the advantage that job stabilization nature is good, the practicality is good.

The push seat 3 comprises two push blocks 31 arranged in a stacked mode at intervals and a first pin shaft 32 for connecting the two push blocks 31, a push plate 33 matched with the output end of the driving piece 2 in a contact mode is arranged between the push blocks 31, the push plate 33 is sleeved on the first pin shaft 32, gaskets are arranged between the push plate 33 and the push blocks 31 on two sides respectively, a second pin shaft which is used for connecting the push plate 33 and the push blocks 31 and preventing the push plate and the push plate from rotating relative to each other is further arranged between the push plate 33 and the push blocks 31, the two push blocks and one push plate are combined into a whole through the second pin shaft and the first pin shaft, the gaskets separate the push plate from the push plate at proper distances, when the output end of the driving piece exerts acting force on the end portion of the push plate, the whole push seat can swing anticlockwise around the first pin shaft, the upper end of the push seat can be separated from the gear set, after the acting force is withdrawn from the output end of the driving piece, the whole push seat can be driven by the first elastic piece to reset clockwise, and the upper end of the push seat is butted against the gear set again.

Each push plate 33 is provided with a gear groove 36, a rolling shaft 37 movably arranged in the gear groove 36 is arranged between the two push blocks 31, the shell 1 is provided with a second elastic part 13, one end of the second elastic part 13 is in interference fit with the shell 1, and the other end of the second elastic part is in interference fit with the rolling shaft 37; when the driving member 2 drives the pushing seat 3 to swing counterclockwise and separate from the gear set 4, the rolling shaft 37 has a first action of moving from the left end to the right end of the gear groove 36 under the action of the second elastic member 13, and when the driving member 2 cancels the acting force and the pushing seat 3 is driven by the first elastic member 11 to collide with the gear set 4 again, the rolling shaft 37 has a second action of moving from the right end of the gear groove 36 and separating from the left end under the action of the second elastic member 13, as shown in fig. 2, when the upper end of the pushing seat abuts against the gear set, the rolling shaft is at the left end of the gear groove, and after the driving member applies the acting force to the pushing plate, the pushing seat swings counterclockwise and separates from the gear set, at this time, the rolling shaft moves to the right end of the gear groove under the action of the second elastic member, and the pushing seat and the gear set keep a certain distance, so that the gear set can rotate freely and cannot be locked;

after the acting force of the driving piece is cancelled, the first elastic piece on the right side of the pushing seat can push the pushing seat to be pulled rightwards through the pretightening force and enable the pushing seat to swing clockwise, the upper end of the pushing seat is abutted to the gear set again, the second elastic piece adopts a torsion spring and has a blocking effect on the rolling shaft, and therefore when the pushing seat swings rightwards, the rolling shaft can move towards the left end of the gear groove.

A plurality of first ratchets 421 arranged in a unidirectional manner are arranged on the circumferential direction of the small gear 42, a plurality of second ratchets 411 opposite to the first ratchets 421 in direction are arranged on the circumferential direction of the large gear 41, and the push block 31 is provided with a clamping table 38 in interference fit with the first ratchets 421; the first ratchet is in interference fit with the clamping table, the pinion cannot rotate anticlockwise and can only rotate clockwise, the direction definition here can be as shown in fig. 2, after the locking rod enters the groove, the gearwheel can only rotate reversely and can be matched with the groove to lock foreign objects, and the gearwheel cannot rotate anticlockwise due to the fact that the pinion cannot rotate anticlockwise, so that the locking effect is guaranteed.

Pinion 42 quantity is two and is located gear wheel 41 both sides respectively, ejector pad 31 respectively with pinion 42 one-to-one, guarantee the stability of structure.

An insertion port 5 located on one side of the groove 12 is further installed in the shell 1, an elastic contact piece 51 and a fixed contact 52 are arranged on the insertion port 5, a roller 53 is arranged on the elastic contact piece 51, a locking seat 6 which is independently arranged and corresponds to the groove 12 is arranged outside the shell 1, a locking rod 61 corresponding to the gear set 4 and the groove 12 is arranged on the locking seat 6, the locking rod 61 is in contact with the roller 53 in the process of being inserted into the groove 12, when the roller 53 is contacted, the elastic contact piece 51 is in contact with the fixed contact 52 and is powered on, and when the roller 53 is separated, the elastic contact piece 51 is separated from the fixed contact 52 and is powered off; after the locking rod enters the groove, the locking rod touches the roller, and the roller transmits acting force to the elastic contact piece to enable the elastic contact piece to be in contact with the fixed contact, so that electrification is realized;

after the locking lever breaks away from the groove, the elastic contact piece recovers the original state and breaks away from the fixed contact, and power failure is realized.

In this embodiment, the driving member 2 is a telescopic motor, and the first elastic member is a tension spring.
