Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
As shown in figure 1, the prior conventional lock tongue device is characterized in that a connecting sheet 3 is connected with the end part of a lock tongue 2, the connecting sheet 3 and a lock shell 1 can slide mutually, a poking hole 4 is formed in one side of the connecting sheet 3, a poking block 5 protruding from a knob rotating element 6 is inserted into the poking hole 4, when the knob rotating element 6 is correspondingly inserted into a proper key or knob poking piece, the connecting sheet 3 can be poked by rotating the knob rotating element 6, and the moving direction of the connecting sheet 3 is directly influenced by the rotating direction of the knob rotating element 6, so that the lock tongue 2 can be ejected or retracted into the lock shell 1.
If the knob 6 is disposed at the position shown in fig. 1, a larger gap exists between the connecting piece 3 and the lock case 1, and the gap cannot be utilized, so that the whole lock tongue device occupies more space of the lock case 1; if the knob 6 is disposed near the bottom of the connecting piece 3, the moving distance of the connecting piece 3 may be reduced, which may cause the knob 6 not to normally rotate or the lock tongue 2 not to fully retract into the lock case 1; if the width of the lock shell 1 is increased, the whole volume of the lock shell 1 is increased, the production and manufacturing cost is increased, and the popularization and the sale of the lock body are not facilitated.
The present embodiment provides a lock tongue device driven by a connecting rod 8, which is applied in an electronic lock body or a mechanical lock body, occupies a smaller space in the lock shell 1, and improves the utilization rate of the space in the lock shell 1.
As shown in fig. 2 to 7, the lock body includes a lock case 1, a lock hole is provided on a front panel 101 of the lock case 1, wherein the lock hole is used for accommodating a lock tongue 2, one lock hole corresponds to one lock tongue 2, and the lock tongue 2 correspondingly passes through the lock hole to realize that the lock case 1 is ejected out or retracted into the lock case 1.
The lock tongue 2 can be provided with a lock tongue 2 structure such as a square tongue, a bevel tongue or a safety tongue, and the lock tongue 2 structure can realize door locking action when being ejected out of the lock hole, and can realize door opening action when being retracted into the lock hole. The same locking bolt 2 may be disposed at two side ends or a middle position of the front panel 101 of the lock case 1, and the position of the locking bolt 2 may be adjusted according to practical situations, in this embodiment, the locking bolt 2 and the corresponding locking bolt device are distributed at one side end of the front panel 101 of the lock case 1, that is, the locking bolt 2 and the locking bolt device are disposed at a position close to the side 102 of the lock case 1, so that the position of the edge of the lock case 1 may be fully utilized to the maximum.
The end part of the lock tongue 2 is fixedly connected with the connecting sliding sheet 9, the connecting sliding sheet 9 is in sliding connection in the lock shell 1, and the connecting sliding sheet 9 and the lock shell 1 can slide relatively, so that the lock tongue 2 is driven to pop up or retract into the lock shell 1.
The sliding connection between the connecting sliding vane 9 and the lock shell 1 can be realized by arranging a sliding block at the bottom of the connecting sliding vane 9, the lock shell 1 is provided with a sliding rail, and the sliding block can realize the sliding connection between the connecting sliding vane 9 and the lock shell 1 when moving back and forth on the sliding rail; in addition, the strip-shaped hole 902 is formed in the connection sliding sheet 9, the limit rod 903 is arranged on the lock shell 1, after the lock shell 1 is sleeved outside the limit rod 903, the connection sliding sheet 9 slides back and forth along the limit rod 903 by means of the strip-shaped hole 902, and the thickness between the connection sliding sheet 9 and the lock shell 1 can be reduced by the structure, so that the overall thickness of the lock body is reduced. In this embodiment, the strip-shaped hole 902 is formed on a side, which is close to the lock case 1, outside the horizontal center line (e.g., the O-line in fig. 2) of the connection sliding piece 9, so that the structure of the connection sliding piece 9 is more compact, which is beneficial to reducing the volume; and the strip-shaped hole 902 is parallel to the side 102 of the lock case 1, so that the connection sliding sheet 9 can move along the side 102 direction of the lock case 1 when moving, and the spring bolt 2 is prevented from being ejected or retracted due to the deviation in the moving process of the connection sliding sheet 9.
In this embodiment, a notch 901 is provided at a position away from the outer edge of the lock case 1 outside the horizontal center line (e.g., O-line in fig. 2) of the connecting sliding vane 9, and the notch 901 extends from the outer edge of the connecting sliding vane 9 to the horizontal center line of the connecting sliding vane 9, so that the connecting sliding vane 9 has a bevel edge, and the size of the connecting sliding vane 9 can be further reduced by the notch 901, so that a sufficient installation space is provided for other parts.
In addition, a pin hole is formed on the connecting sliding sheet 9, and the pin hole can be used for connecting the connecting sliding sheet 9 and the connecting rod 8 after being inserted into a pin rod; because the connecting sliding vane 9 is generally made of metal, the step of forming the pin hole in the connecting sliding vane 9 made of metal is generally performed by adopting a drilling mode, in order to avoid that the pin hole is too close to the edge position of the connecting sliding vane 9 to cause cracks of the connecting sliding vane 9 during drilling, the position of the hole formed by the pin hole is arranged at the position of the connecting sliding vane 9 close to the middle, and the shortest distance from the pin hole to the bevel edge is kept to be the same as the shortest distance from the pin hole to the front side edge of the connecting sliding vane 9 for connecting the end part of the lock tongue 2, thereby improving the yield of the connecting sliding vane 9; meanwhile, the connecting rod 8 is connected to the pin hole through the pin rod, so that the connecting rod 8 can rotate by taking the pin rod as an axis under the drive of external force, and then the connecting sliding vane 9 is driven to horizontally reciprocate back and forth, because the connecting rod 8 is used for providing forward or backward moving force for the connecting sliding vane 9, if the position of the pin hole is too close to the edge of the connecting sliding vane 9, the connecting rod 8 drives the pin rod to push the connecting sliding vane 9 to move, the situation that the connecting sliding vane 9 is broken due to long-term impact possibly occurs, and the moving stability of the connecting sliding vane 9 is affected.
Secondly, in order to minimize the overall volume of the latch bolt assembly, the pin hole is disposed as close as possible to the side 102 of the lock case 1, so that the pin hole is disposed at a side of the connecting slide 9, which is close to the lock case 1, outside the horizontal center line (e.g., the line O in fig. 2), so that the knob 6 connected by the link 8 can be also disposed at a position close to the side 102 of the lock case 1, thereby reducing the gaps between the connecting slide 9, the knob 6 and the lock case 1.
The knob element 6 is arranged on the extension line of the moving path of the connecting sliding sheet 9, namely, the knob element 6 is arranged at the rear of the connecting sliding sheet 9, so that the knob element 6 can be ensured to normally rotate and the knob element 6 can be prevented from occupying excessive space. The knob assembly 6 may be driven to rotate by inserting a corresponding key or knob dial, the knob assembly 6 extends outwards to form a connection portion 602, and the connection portion 602 and the knob assembly 6 may be driven to rotate synchronously when the knob assembly 6 rotates. The knob component 6 can be in pin connection with the connecting rod 8 through the connecting part 602, so that one end of the connecting rod 8 is in pin connection with the connecting sliding sheet 9, the other end of the connecting rod 8 is in pin connection with the connecting part 602, and the knob component 6 can drive the connecting sliding sheet 9 to move back and forth through the connecting rod 8 when rotating, so that the lock tongue 2 can be ejected or retracted into the lock shell 1.
When the lock tongue 2 is completely ejected out of the lock case 1, a gap for sliding the connection sliding sheet 9 is formed between the knob element 6 and the connection sliding sheet 9, the width of the gap between the knob element 6 and the connection sliding sheet 9 is equal to the maximum sliding distance of the connection sliding sheet 9, and the maximum sliding distance of the connection sliding sheet 9 is equal to the length of the lock tongue 2 exposed out of the lock case 1 when the lock tongue 2 is completely ejected out of the lock case 1; namely, when the connecting sliding vane 9 moves backwards to the maximum sliding distance, the lock tongue 2 can be driven to retract into the lock shell 1 completely, and the edge line of the connecting sliding vane 9 can be close to the outer contour of the knob piece 6, so that the structure of the whole lock tongue device is more compact, the space in the lock shell 1 is fully utilized, and the space waste is reduced.
In this embodiment, the keyhole 601 on the knob member 6 is set as a square hole, when the lock tongue 2 is completely ejected out of the lock case 1, the keyhole 601 of the knob member 6 is in a horizontal state, when the knob member 6 rotates 90 ° to enable the lock tongue 2 to be completely retracted into the lock case 1, the direction of the keyhole 601 is in a vertical direction, and the keyhole 601 and the connection part 602, the connection part 602 and the pin connection point of the connecting rod 8 are located on the same vertical line, so that a user can clearly know what state the key is twisted to when unlocking the lock by using the key, namely when the key is twisted to the vertical state, the lock tongue 2 is completely retracted into the lock case 1, and then the door can be opened; when the key is turned to a horizontal state, the lock tongue 2 is completely ejected out of the lock shell 1 at the moment, so that the door locking action is completed; therefore, the situation that the key angle is too large or too small is avoided, the normal operation of each linkage part in the lock shell 1 is influenced by the fact that the key angle is not twisted in place, and the lock tongue 2 is forced to open the door by a user in the state of incomplete retraction, so that the lock tongue 2 and a door frame are subjected to violent impact, the lock tongue 2 is damaged, and the whole service life of the lock body is influenced.
In addition, the knob 6 is further provided with a supporting portion 603, and the supporting portion 603 is used for limiting the rotation direction and the rotation angle of the knob 6, so as to prevent the excessive rotation of the knob 6 from affecting the linkage action of each structure in the lock case 1. The rotation range of the knob member is 0-90 °, when the knob member 6 is in the 0 ° state, the abutting portion 603 abuts against the side 102 of the lock case 1, and the connecting portion 602 is parallel to the side 102 of the lock case 1, at this time, the distance from the outermost end of the connecting portion 602 to the front panel 101 of the lock case 1 is minimum, so that the lock tongue 2 is completely ejected out of the lock case 1, and keeps the state all the time without external force.
When the knob 6 rotates 90 ° clockwise, the connecting portion 602 is perpendicular to the side 102 of the lock case 1, and the connecting portion 602 drives the connecting rod 8 to pull the connecting slide 9 backward, so that the lock tongue 2 can be completely retracted into the lock case 1.
In order to realize the automatic reset function of the lock tongue 2, a torsion spring 7 is arranged on the lock shell 1, one end of the torsion spring 7 is stopped on a stud on the lock shell 1, the other end of the torsion spring 7 is connected with the supporting part 603, when the lock tongue 2 is completely ejected out of the lock shell 1, the torsion spring 7 is in a loose state, when the knob element 6 rotates, the connecting part 602 of the torsion spring is synchronously rotated with the knob element 6, the torsion spring 7 is in a tight state, and when the knob element 6 is not applied with external force, the torsion spring 7 can drive the knob element 6 to reversely rotate when the knob element 6 is restored to the loose state, so that the connecting slide 9 is driven by the connecting rod 8 to eject the locking again out of the lock shell 1.
In order to make the knob element 6 get close to the side 102 of the lock case 1 as much as possible, so as to avoid too much unavailable space between the knob element 6 and the lock case 1, the connecting rod 8 connecting the connecting slide 9 and the knob element 6 is set to be a bent structure, the specific structure of the connecting rod 8 can be changed according to the actual locking and the position of the knob element 6, the connecting rod 8 can be set to be a bent structure, and also can be set to be an arc structure, so long as the pin connection position of the connecting rod 8 and the connecting part 602 is ensured to be lower than the pin connection position of the connecting rod 8 and the connecting slide 9, the knob element 6 can be made to be as close to the side 102 of the lock case 1 as possible; in this embodiment, the connecting rod 8 is configured as an arc structure, the arc angle range of the connecting rod 8 is 25 ° to 35 °, the arc angle of the connecting rod 8 is preferably 30 °, and the arc opening of the connecting rod 8 faces the side 102 of the lock case 1, so that when the lock tongue 2 is completely ejected out of the lock case 1 of the lock tongue 2, the pin connection (e.g. point a in fig. 3) between the connecting rod 8 and the connecting slide 9 is closer to the side 102 of the lock case 1 than the pin connection (e.g. point B in fig. 3) between the connecting rod 8 and the connecting part 602, thereby greatly reducing the distance between the knob 6 and the side 102 of the lock case 1; when the locking is completely retracted into the lock case 1, the pin connection (e.g., point a in fig. 6) between the connecting rod 8 and the connecting portion 602 is closer to the side 102 of the lock case 1 than the pin connection (e.g., point B in fig. 6) between the connecting rod 8 and the connecting slide 9, so that the knob member 6 may be as close to the side 102 of the lock case 1 as possible, and the movement range of the whole lock tongue device is reduced during the movement process, so that the lock tongue device is prevented from occupying too much space inside the lock case 1, and the space utilization in the lock case 1 is improved.
