In some embodiments, the first driving member 20 is a solenoid valve disposed on the mounting base plate 10, and in this case, an output shaft of the first driving member 20 is an armature of the solenoid valve, wherein the solenoid valve is of a conventional structure, and a specific principle thereof is not described herein. That is, when the first driving member 20 is a solenoid valve, the lock structure of the present invention is an electromagnetic lock. When the first driving member 20 is an electromagnetic valve, in a non-energized state, the armature of the electromagnetic valve can move under the action of an external force, that is, when the second driving member drives the slider to move upward, the clamping plate 311 drives the armature of the electromagnetic valve to move upward.

In other embodiments, the first driving member 20 may also be an electric push rod, an air cylinder, or a hydraulic cylinder, and at this time, the output shaft is a telescopic rod of the electric push rod, the air cylinder, or the hydraulic cylinder, and then the sliding plate 30 is driven to move along the vertical direction by the telescopic rod. Because the driving structures such as the electric push rod, the air cylinder or the hydraulic cylinder have a self-locking function, in a normal state, the second driving part cannot push the sliding plate 30 to move, and therefore, if the design mode is used, when the first driving part 20 cannot work, the clamping plate 311 can be separated from the limiting groove, so that the second driving part can play a role. Specifically, can set up the layer board at the tip of telescopic link, cardboard 311 is in the top of layer board, and then the accessible layer board drives cardboard 311 upward movement, and in addition, the mode that sets up of layer board can not influence the second driving piece and drive slide 30 upward movement.

In other embodiments, the first driving member 20 is configured to be self-locking, i.e. the output shaft is not movable in the vertical direction by external force, and thus the second driving member is not able to push the slide plate to move under normal conditions. Therefore, with this design, the output shaft of the first driving member 20 is detachably connected to the bent portion 31. That is, when the first driving element 20 cannot drive the sliding plate 30 to move in the vertical direction, the output shaft of the first driving element 20 is separated from the bending portion 31, so that the sliding plate 30 can be driven by the second driving element to move, and the influence on the operation of the second driving element is avoided.

Take the arrangement mode that the joint of the bending part 31 and the output shaft is provided with two clamping plates 311 as an example, at this moment, the periphery of the output shaft is provided with a limiting groove which is in limiting fit with the clamping plates 311 along the vertical direction. The two catching plates 311 are provided to be movable in a horizontal direction with respect to the bent portion 31 so that the two catching plates 311 come close to or come away from each other. Specifically, the two clamping plates 311 are two first wedge-shaped plates which are oppositely arranged, and narrow edge portions of the first wedge-shaped plates are arranged in a direction away from the mounting baseplate 10. Be equipped with first spring between one side that two first wedge boards carried on the back mutually and kink 31, the extending direction of first spring is unanimous with the moving direction of first wedge board, and first spring provides elasticity for first wedge board for two first wedge boards draw close, and then make two first wedge boards clamp in the position department of the spacing groove of output shaft, make kink 31 follow the output shaft and remove along vertical direction. Lock structrual installation is on the mounting bracket of assigned position, for example, when the lock structure is used for subway shield door system, the lock structrual installation is on the corresponding mounting bracket of shield door system, the mounting bracket of lock structure and two corresponding position departments of first wedge-shaped plate are equipped with two second wedge-shaped plates, and two second wedge-shaped plates set up back to each other mutually, the narrow limit portion of two second wedge-shaped plates is towards first wedge-shaped plate, and first wedge-shaped plate and second wedge-shaped plate phase-match, when making the second wedge-shaped plate move towards first wedge-shaped plate direction, two second wedge-shaped plates of accessible promote two first wedge-shaped plates and keep away from, and then make first wedge-shaped plate break away from the spacing groove, remove being connected of axis of rotation and kink 31, and then make the second driving piece can drive slide 30 and remove along vertical direction.

Wherein, the one end that first wedge was kept away from to the second wedge is passed through the connecting plate and is connected, and the one end that the second wedge was kept away from to the connecting plate is equipped with the catch bar, the catch bar stretches out the mounting bracket and can supply the staff to press, the periphery cover of catch bar is equipped with the second spring, the one end and the connecting plate of second spring are connected, the other end is connected with the mounting bracket, and then provide the pulling force for the connecting plate through the second spring, make the second wedge have towards the trend of the direction motion that deviates from first wedge, the second wedge is under the effect of not receiving the external force promptly, with the separation of first wedge, avoid influencing the removal of slide. Further optimally, in order to avoid slide 30 at the removal in-process along vertical direction, first wedge breaks away from with the second wedge, leads to two first wedge resets, and the first wedge of this application has certain thickness with the second wedge for slide 30 removes the in-process, and first wedge is laminated with the second wedge all the time.

Under the normality, output shaft and cardboard 311 are spacing along vertical direction, and accessible first driving piece drives slide 30 and removes for jam plate 40 unblock, and jam plate 40 can rotate for mounting plate 10 promptly. When abnormal state appears, staff's accessible is pressed the catch bar for two first wedge plate back-to-back motion, and then break away from the spacing groove, rethread second driving piece drive slide 30 rebound, make the unblock of jam plate 40. Therefore, the design mode can ensure the use safety of the sliding door 50, and avoid the situation that the sliding door 50 is opened in the use state of the train due to misoperation of the second driving piece by passengers or other personnel, thereby ensuring the safety of passengers outside the station and the normal running of the train.

In some embodiments, when the lock structure of the present application is applied to opening and closing of the sliding door 50, the second driving member may be disposed on the sliding door 50, and specifically, the second driving member may include a push rod and a suspension switch for driving the push rod to move up and down, that is, the suspension switch is disposed on the sliding door 50, a rotation shaft of the suspension switch extends to the inside of the sliding door 50, and one end of the rotation shaft extending to the sliding door 50 is provided with a second cam. The jack is disposed inside the sliding door 50 in the vertical direction, and the bottom end of the jack contacts the outer periphery of the second cam. Normally, the second cam is rotated to a first position, at which time a certain distance exists between the top end of the ejector pin and the push plate 32. Under emergency, the switch is twisted in the rotatory hanging of accessible for the second cam rotates towards second position direction, and the long limit direction of second cam rotates promptly, and at this moment, accessible second cam drives the ejector pin upward movement, and then pushes up the push pedal 32 on through the ejector pin, and then drives slide 30 upward movement, makes slide 30 reach the unblock position, and then can open sliding door 50. By adopting the design mode, the sliding door 50 can be smoothly opened under the emergency condition, and the passengers can be ensured to smoothly escape.
