In this embodiment, a lock body structure is disclosed, please refer to fig. 1 to 4, and the lock body structure includes a housing 1, a lock tongue 2, a lock tongue slider 3, an inner dial peach 5, an outer dial peach 6 and a locking block 4. The housing 1 may be formed by two parts which are fastened together, the middle part forming a space in which other components can be accommodated, the structure of only one half-shell of the housing 1 being shown in the respective figures to show its internal construction. One side of the shell 1 is provided with a lock tongue hole, the lock tongue 2 is slidably arranged at the side, and the lock tongue 2 stretches out and draws back in the lock tongue hole to realize unlocking and locking.
The lock tongue slider 3 is slidably disposed in the housing 1, one end of the lock tongue slider 3 is connected to the lock tongue 2 and slides synchronously with the lock tongue 2, and an unlocking portion 31 is formed on a side surface of the lock tongue slider 3. The sliding assembly between the lock tongue sliding block 3 and the housing 1 and the sliding assembly between other structures in the following may be realized by adopting structures such as a chute, a sliding rail, a sliding rod, etc. in the prior art, which will not be described in detail. In this embodiment, the tongue 2 is a magnetic tongue that can slide out of the housing 1 when opposed to the tongue box 10 having the magnet. Specifically, when the lock tongue buckle box 10 is opposite to the lock tongue buckle box 10, the lock tongue buckle box can be attracted by a magnet in the lock tongue buckle box 10 and automatically moved into the lock tongue buckle box 10, so that locking is realized.
The inner dialing peach 5 and the outer dialing peach 6 are coaxially rotated and arranged in the shell 1, and can be connected with a handle of a door when the inner dialing peach is used, and a user can rotate the two handles to dial the peach through the handle. The inner dialing peach 5 and the outer dialing peach 6 face the inner side and the outer side of the door leaf respectively during actual installation and are respectively connected with the inner handle and the outer handle, and a user can rotate one of the dialing peaches in or out of the door.
The periphery of the inner dial peach 5 is provided with a first bump 51 opposite to the unlocking part 31, when in a locking state, the unlocking part 31 is positioned on a rotating path of the first bump 51 along a first direction, at the moment, the inner dial peach 5 is rotated towards the first direction, the first bump 51 can be abutted against the unlocking part 31, and then the lock tongue sliding block 3 is driven to slide towards the unlocking side, so that unlocking is realized. The outer circumference of the outer dial peach 6 is formed with a second bump 61 and a third bump 62 along the circumferential direction, wherein the second bump 61 is opposite to the unlocking part 31, when in a locked state, the unlocking part 31 is positioned on a rotating path of the second bump 61 along the first direction, the outer dial peach 6 is rotated along the first direction at this time, the second bump 61 can be abutted against the unlocking part 31, and then the lock tongue sliding block 3 is driven to slide towards the unlocking side, so that unlocking is realized.
The lock block 4 is rotatably provided in the housing 1, and a fourth projection 41 is formed on the outer periphery thereof, the fourth projection 41 being on the rotational path of the first projection 51 in the second direction and on the rotational path of the third projection 62 in the first direction. When the inner dial peach 5 rotates along the second direction, the first bump 51 abuts against the side surface of the fourth bump 41, and drives the locking block 4 to rotate along the first direction, so that the end surface of the fourth bump 41 abuts against the side surface of the third bump 62, and at this time, the length direction of the fourth bump 41 is tangential to the outer dial peach 6, so that the rotation of the outer dial peach 6 can be limited.
Specifically, referring to fig. 2a to 3c, the lock body structure in fig. 2a is in an initial unlocking state, in which the lock tongue 2 is retracted into the housing 1, and the lock tongue slider 3 slides to the right side in the housing 1. When the latch bolt 2 is moved into the latch bolt housing 10, the latch bolt slider 3 moves leftward with it, eventually taking the state shown in fig. 2b, at which time the unlocking portion 31 is opposed to the first and second projections 51 and 61. If the inner dial peach 5 is rotated clockwise, the first bump 51 abuts against the unlocking part 31 to drive the lock tongue sliding block 3 to slide rightwards, the lock tongue 2 is moved into the shell 1 to complete unlocking, and if the outer dial peach 6 is rotated clockwise, the second bump 61 abuts against the unlocking part 31 to drive the lock tongue sliding block 3 to slide rightwards, the lock tongue 2 is moved into the shell 1, and unlocking can be completed. Fig. 2c shows the process of unlocking by turning the outer dial 6 clockwise.
In the locking state, the lock body structure can be reversely locked by rotating the inner dial peach 5 anticlockwise, and the subsequent outer dial peach 6 cannot be rotated clockwise to unlock. Referring to fig. 3a, when the inner dial 5 rotates counterclockwise, the first bump 51 abuts against the side surface of the fourth bump 41 to drive the locking block 4 to rotate clockwise, and the end surface of the corresponding fourth bump 41 rotates to the side surface of the third bump 62. At this time, when the outer dial 6 rotates clockwise, the third bump 62 abuts against the end face of the fourth bump 41, and the locking block 4 cannot be driven to rotate, so that the outer dial 6 cannot rotate clockwise, and thus, the back locking is realized.
In the back-locking state, the lock block 4 only limits the outward turning peach 6, so that the lock can be unlocked when the inward turning peach 5 is rotated clockwise.
The lock body structure in this embodiment cancels the back locking knob in the traditional door lock, directly utilizes the cooperation of the inner dial peach 5 and the locking block 4, and can realize the functions of back locking and unlocking when the inner dial peach 5 rotates in the forward direction/the reverse direction. The structure inside the lock body is simplified, the stability of the lock body during operation is improved, and the lock body structure can be ensured to stably operate for a long time.
In this embodiment, the fourth bump 41 is disposed on the lower side of the first bump 51 and the upper side of the third bump 62, so that when the inner dial 5 is rotated counterclockwise, the locking block 4 is driven to rotate clockwise to limit the outer dial 6. Correspondingly, the first direction refers to the clockwise direction in the drawings, and the second direction refers to the counterclockwise direction in the drawings. In other embodiments, the positional relationship between the inner dial peach 5, the outer dial peach 6 and the locking block 4 can be changed according to actual requirements, and the inner dial peach 5 is rotated in two opposite directions when unlocking and counter locking are performed finally.
It should be noted that when the lock body structure is in an unlocking state, that is, when the lock tongue 2 moves into the housing 1, if the inner dial peach 5 rotates anticlockwise according to the above manner, the lock body structure can be in a back locking state, and at this time, the outer dial peach 6 and the outer handle connected with the outer dial peach can not rotate, so that the normal use of the lock body structure is affected. For this reason, a fifth bump 52 is further formed on the inner dial peach 5, and a limit portion 32 is formed on the lock tongue slider 3, when the lock tongue 2 enters the housing 1 along with the lock tongue slider 3, the limit portion 32 abuts against the fifth bump 52 to limit the rotation of the inner dial peach 5 in the counterclockwise direction, so that the back lock cannot be realized. In other words, when the lock tongue 2 moves into the housing 1, the lock body structure cannot be in the back locking state by rotating the inner dial 5, so that the phenomenon of misoperation back locking when a door leaf of a user is opened is avoided.
Further, in this embodiment, an unlocking push rod 7 is also provided in the housing 1 for releasing the back-lock state at the same time when unlocking by the inner handle in the back-lock state. Specifically, referring to fig. 3b and 3c, the unlocking push rod 7 and the lock tongue slider 3 are slidably disposed in the housing 1, the left end of the unlocking push rod is fixedly connected with the lock tongue 2, and a sixth protrusion 42 is formed on the outer periphery of the locking block 4. In the back locking state, the rotation of the outer dial 6 is limited, and at this time, when the inner dial 5 is unlocked by rotating clockwise, the unlocking push rod 7 is driven by the lock tongue 2 to move to the unlocking side (i.e. right side in the drawing) and is propped against the side surface of the sixth bump 42, so that the locking block 4 is driven to rotate anticlockwise to enable the fourth bump 41 to be far away from the third bump 62, and finally the side surface of the first bump 51 is reached, namely, the state shown in fig. 3 c. At this time, the rotation restriction of the outer dial 6 is released, and the locking block 4 returns to the initial position, and the subsequent counter-clockwise rotation of the inner dial 5 can continue to realize the counter-lock.
In other embodiments, the setting positions of the unlocking push rod 7, the locking block 4 and the sixth bump 42 can be changed according to actual demands, and the unlocking and unlocking can be simultaneously realized by the inner shift lever 5 by only ensuring that the unlocking push rod 7 can abut against the side surface of the sixth bump 42 when moving to the unlocking side and driving the locking block 4 to rotate so that the fourth bump 41 is far away from the third bump 62.
In this embodiment, an unlocking dial peach 8 is rotatably disposed between the inner dial peach 5 and the outer dial peach 6, and coaxially rotates with the inner dial peach 5, an unlocking groove 82 is formed at the axis of the unlocking dial peach 8, and a groove 81 sleeved on the fourth bump 41 is formed at one side of the unlocking dial peach 8, so that synchronous rotation of the unlocking dial peach 8 and the locking block 4 can be realized, i.e. the unlocking dial peach 8 and the locking block 4 can be regarded as being meshed together. The outer poking peach 6 is provided with a through hole opposite to the unlocking groove 82. The user can rotate the unlocking dial 8 by adopting a preset tool to extend into the unlocking groove 82 in the shell 1 at the outer side, and then rotate the locking block 4 to enable the fourth lug 41 to be far away from the third lug 62, so that unlocking is realized.
Fig. 4 shows the emergency unlocking process by the unlocking dial 8, and as compared with the unlocking state shown in fig. 3a, the clockwise rotation of the unlocking dial 8 can rotate the locking block 4 counterclockwise, and then the fourth bump 41 is far away from the third bump 62, reaches the side surface of the first bump 51, and the unlocking state is released.
In this embodiment, a return spring 9 is further provided in the housing 1, and the left end thereof is connected to the tongue 2, so that a biasing force directed to the unlocking side is indirectly applied to the tongue slider 3. As shown in fig. 2a and 2b, the return spring 9 applies a force to the latch slider 3 toward the right, and when the latch 2 and the latch slider 3 are not subjected to other external forces, the return spring 9 can pull the latch 2 into the housing 1, so as to prevent the latch 2 from colliding with a user or other objects.
For the lock body structure in this embodiment, two shifting peach are arranged in total, instead of the inner and outer handles sharing one shifting peach, so that the inner and outer handles connected with the shifting peach can rotate independently. In the actual installation, there are left and right door leaf opening forms, and correspondingly, the inward turning peach 5 in the lock body structure is respectively positioned at the inner side and the outer side of the door leaf in the two cases. The above functions are realized by connecting the inner dial 5 with the inner handle, and if the inner dial is directly connected with the outer handle, the above functions cannot be realized. Therefore, in order to ensure that the lock body structure can be simultaneously applied to left-opening and right-opening door leaves, the structures of the inner dial peach 5 and the outer dial peach 6 are specifically improved. Referring to fig. 1, a seventh bump 53 opposite to the third bump 62 is formed on the inner dial 5, an inner contact portion 511 protruding toward the outer dial 6 is formed on the first bump 51 along the axial direction, an outer contact portion 611 protruding toward the inner dial 5 is formed on the second bump 61 along the axial direction, and the locking block 4 is slidably disposed in the housing 1 along the axial direction, so that a user can adjust the position of the locking block 4 according to the door opening direction of an actual door leaf.
Specifically, in this embodiment, the fourth bump 41 is on the rotational path of the inner abutment 511 and the third bump 62. When the inner dial 5 is rotated anticlockwise, the inner abutting part 511 drives the locking block 4 to rotate, so that the fourth lug 41 abuts against the third lug 62 to limit the rotation of the outer dial 6. Under this kind of structural style, this lock body structure's interior peach of dialling 5 is established in the inboard that is close to the door leaf, and outer peach 6 of dialling is established in the outside that is close to the door leaf.
When the inner poking peach 5 needs to be arranged at the outer side close to the door leaf, the outer poking peach 6 is arranged at the inner side close to the door leaf so as to adapt to the door opening direction of the door leaf. It is only necessary for the user to slide the lock block 4 in the axial direction so that the fourth projection 41 thereon is in the rotational path of the outer abutment 611 and the seventh projection 53. At this time, the outer dial 6 is rotated counterclockwise, the outer abutting portion 611 drives the locking block 4 to rotate, and then the fourth bump 41 abuts against the seventh bump 53 to limit the rotation of the inner dial 5, so that the back locking function can be realized at one side in the door.
It should be noted that the related structure for realizing the sliding of the locking block 4 along the axial direction is not innovative in the present technical solution, and related structures already exist in the prior art, for example, a through hole is formed in the housing 1, and the locking block 4 can be pushed to move by a tool, so the related structures will not be described in detail.
In addition, in this embodiment, a door lock is also disclosed, including the above-mentioned lock body structure, inner handle and outer handle. Wherein, the one end of interior handle runs through casing 1 and links to each other with interior dial peach 5, and the one end of outer handle runs through casing 1 and links to each other with outer dial peach 6. The user can rotate the inner dial peach 5 by rotating the inner handle, and rotate the outer dial peach 6 by rotating the outer handle, so as to realize various functions in the lock body structure.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
