The sliding block is connected with the base 3 in a sliding mode, and the sliding block can limit other degrees of freedom to ensure that the sliding block moves linearly. The two ends of the spring are respectively connected with the base 3 and the sliding block and are generally arranged along the sliding direction of the sliding block. The locking tongue 23 is typically provided as a solid metal strip, typically circular or square in cross-section, and is secured to the slider. The lower end of the sliding block is provided with an inward concave sliding wall 21, and the sliding wall 21 is provided with a bulge 22. The end of the shifting block 12 is provided with a groove 121 for abutting against the protrusion 22, and the protrusion 22 and the groove 121 can be mutually embedded. Preferably, the base 3 is provided with side walls on the periphery, the side walls are provided with slotted holes, and the lock tongue 23 extends out of the base 3 through the slotted holes. Typically the spring attachment base 3 is located on the side wall at one end and attached to the side of the slider at the other end.
In a preferred embodiment, the plane projection of the sliding wall 21 is formed by a plurality of mutually connected curves, and a smooth transition between the curves is usually arranged to ensure that the tail end of the shifting block 12 slides smoothly on the curves. The number of the protrusions 22 on the sliding wall 21 is 2 and the protrusions are respectively located at two ends of the sliding wall 21, and the transition of the side facing the outside in each protrusion 22 is not smooth for achieving a partial blocking effect on the dial block 12. Usually, the plane projection of the end surface of the shifting block 12 is an arc line, and the smooth sliding on the sliding wall 21 on the shifting block 12 is also ensured. Only one groove 121 can be arranged on the shifting block 12 and used for being embedded in the protrusions 22 at different positions. Preferably, the number of the grooves 121 on the dial 12 is 2, and the grooves are respectively located at the connecting positions of the end face and the side face, namely, at two corners of the end of the dial 12.
In a preferred embodiment, the device further comprises a worm wheel 11 and a worm 42 which are meshed with each other, the shifting block 12 is fixed on the worm wheel 11, and the motor 41 is connected with the worm 42 and drives the worm wheel 11 to rotate. The worm wheel 11 and the worm 42 can obtain a relatively large reduction ratio, and have a relatively great advantage for the motor 41 to drive the shifting block 12 to rotate. Usually, the sliding range of the shifting block 12 can be limited by the side surface of the base 3, but the two side positions of the shifting block 12 on the base 3 are both provided with the limiting blocks 33, so that the shifting block 12 can be effectively prevented from rotating over.
In this embodiment the base 3 in the electric lock cylinder arrangement is provided with straight male tracks 31 and the bottom of the slide is provided with female tracks connected to the male tracks 31. The spring comprises a first spring 24 and a second spring 25 which are respectively positioned at two sides of the sliding block, one end of each of the first spring 24 and the second spring 25 is connected with the sliding block, and the other end of each of the first spring 24 and the second spring 25 is connected with the side wall of the base 3. The knob 13 is arranged on the front face of the base 3, and a plurality of vertical grooves are formed in the side wall of the knob 13, so that the fingers can be prevented from sliding when the knob is twisted. Preferably, an audio device, a sensor and a processor are arranged in the electric mortise lock core structure, the sensor is used for sensing the position of the sliding block and transmitting information to the processor, and the processor controls the audio device to send out corresponding signals after processing. Correspondingly, the sound groove 32 is arranged on the base 3, and sound can be emitted through the sound groove 32.
When the electric lock core structure is applied to an electric lock and installed on a door, the motor 41 is triggered to operate by an electric door card or other triggering device. For convenience of description, but not to represent a specific direction, referring to fig. 3 or 4, the left side of the drawing is defined as left, and the right side of the drawing is defined as right. It can be seen that the left and right sides of the slide wall 21 are provided with the projections 22, and the left and right sides of the end of the slide are also provided with the projections 22. When the motor 41 is started to drive the worm 42 to rotate, the worm 42 is meshed with the turbine 11 to drive the shifting block 12 to rotate rightwards, and the tail end of the shifting block 12 abuts against the sliding wall 21 of the sliding block to drive the sliding block to move. During this process, the first spring 24 is extended and the second spring 25 is compressed. When the shifting block 12 rotates to a certain angle, the groove 121 on the left side of the tail end of the shifting block 12 is embedded with the right protrusion 22 of the sliding block, and the motor 41 stops rotating. Due to the tensile force of the first spring 24 and the tensile force of the second spring 25, the groove 121 on the left side of the shifting block 12 compresses the protrusion 22 on the right side of the sliding block, and a certain self-locking effect is achieved. The locking tongue 23 now extends out of the base 3. When the door needs to be opened, the motor 41 is started again, the motor 41 rotates reversely, the worm 42 is meshed with the turbine 11 to drive the shifting block 12 to rotate leftwards, the shifting block 12 is subjected to a large acting force, the groove 121 on the left side of the shifting block 12 is enabled to be separated from the protrusion 22 on the right side of the sliding block, and the tail end of the shifting block 12 abuts against the sliding wall 21 of the sliding block to drive the sliding block to move. In the process, the first spring 24 is gradually shortened and the second spring 25 is extended. When the shifting block 12 rotates to a certain angle, the groove 121 on the right side of the tail end of the shifting block 12 is embedded with the left protrusion 22 of the sliding block, and the motor 41 stops rotating. Due to the tensile force of the first spring 24 and the tensile force of the second spring 25, the groove 121 on the right side of the tail end of the shifting block 12 compresses the protrusion 22 on the left side of the sliding block, and a certain self-locking effect is achieved. The latch tongue 23 is now retracted into the base 3.
When the knob 13 is used for controlling the bolt 23 of the electric mortise lock core structure to extend out, the knob 13 is rotated to directly drive the turbine 11 to rotate, and the shifting block 12 is rotated rightwards to drive the sliding block to move rightwards. At this time, under the action of the tension of the first spring 24 and the tension of the second spring 25, the slider is urged to move rightwards, so that the effort required for rotating the knob 13 is reduced, and the user experience is further improved. When the shifting block 12 rotates to a certain angle, the groove 121 on the left side of the shifting block 12 is embedded with the right protrusion 22 of the sliding block, and the extension of the bolt 23 is completed. When the bolt 23 of the electric lock core structure is controlled to retract by the knob 13, the worm wheel 11 is directly driven to rotate by rotating the knob 13. At this time, the force provided by the finger causes the groove 121 on the left side of the end of the block to disengage from the right protrusion 22 of the slider, and the dial block 12 rotates to the left to drive the slider to move to the left. Meanwhile, under the action of the tension of the first spring 24 and the tension of the second spring 25, the assisting sliding block can be promoted to move leftwards, so that the rotating hand feeling is smooth, and a large blockage cannot be felt. When the shifting block 12 rotates to a certain angle, the groove 121 on the right side of the shifting block 12 is embedded with the left protrusion 22 of the sliding block, and the retraction of the bolt 23 is completed.
Of course, the design creation is not limited to the above embodiments, and the combination of different features of the above embodiments can also achieve good effects. Those skilled in the art can make equivalent changes or substitutions without departing from the spirit of the present invention, and such equivalent changes or substitutions are included in the scope defined by the claims of the present application.
