Description

Technical Field

[0001] This utility model relates to the field of door lock body technology, and more specifically to a one-way controlled reverse lifting lock body structure. Background Technology

[0002] To simplify the locking process, many existing technologies utilize a reverse-lift (uplift) handle for locking. For example, CN117052229B discloses a reverse-lift locking lock body with rotatably connected square chips on both sides of its dial. These square chips are connected to the inner and outer handles of the door, respectively. The dial has a movable adapter with a first position and a second position. In the first position, when the square chip rotates in the unlocking direction, the adapter is positioned on the unlocking rotation stroke of the square chip and abuts against it to drive the dial's rotation. The lock also includes a linkage B. When the square chip rotates in the locking direction, the linkage B can drive the adapter to move to the second position, disengaging it from the unlocking rotation stroke of the square chip.

[0003] However, some shortcomings were found in the existing technology during use. First, the lock body of the aforementioned patent can be locked by lifting either the outer or inner handle in reverse (upward). This lock body structure is generally used for indoor magnetic door locks. In practice, indoor doors are usually locked from inside the room, and people outside rarely need to lock them. The existing structure often locks due to accidental lifting of the outer handle, requiring the outsider to use a key to open the door, which is inconvenient. Second, another problem is that the existing reverse-lift locking works regardless of whether the door is open or closed. In the case of magnetic door locks, whether the bolt is extended or retracted does not affect the reverse-lift locking mechanism. This means that when the door is open, accidental lifting can lock the lock body. When the door is closed, the bolt extends due to magnetic attraction, and the door automatically locks, which is not the desired locking mechanism.

[0004] Therefore, based on the problems encountered in use mentioned above, this application is proposed to solve these problems, making the use of the lock body more user-friendly and avoiding inconvenience caused by misoperation. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a one-way control reverse lifting lock body structure, which cannot be lifted to lock the door, and cannot be lifted to lock the door when the door is not closed properly, thus avoiding inconvenience caused by misoperation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a one-way controlled reverse lifting lock body structure, including a lock shell, a telescopic lock tongue and a driving component for driving the lock tongue inside the lock shell, characterized in that: the driving component includes a rotatable dial wheel and an inner and outer chip rotatably disposed on both sides of the dial wheel and respectively connected to the inner and outer handles, the dial wheel is provided with a lock block that can swing and abut or separate from both the inner and outer chips, and the dial wheel is provided with a connecting pin that cooperates with the inner chip;

[0007] When the inner or outer chip rotates in the unlocking direction, both the inner and outer chips can drive the dial to rotate in the unlocking direction through the opposing lock blocks.

[0008] When the inner chip rotates in the locking direction, it can drive the dial to rotate in the locking direction through the connecting pin, thus separating the lock block from both the inner and outer chips.

[0009] The present invention is further configured such that: a blocking part is provided on the lock tongue, and a limiting part is provided on both the inner and outer chips; when the lock tongue retracts into the lock housing, the blocking part abuts against the limiting part to prevent the inner and outer chips from rotating in the locking direction.

[0010] The present invention is further configured such that: the connecting pin and the dial are detachably configured; both the inner and outer chips are provided with arc-shaped segments that abut against the connecting pin; when the inner chip rotates in the locking direction, the arc-shaped segments abut against the connecting pin and drive the dial to rotate in the locking direction.

[0011] The present invention is further configured such that the arc-shaped segment is a notch, and when the inner chip rotates, the notch and the connecting pin abut against each other to drive the dial to rotate.

[0012] The present invention is further configured such that a transmission misalignment is provided between the notch and the connecting pin.

[0013] The present invention is further configured such that: a switching pin is fixedly provided inside the lock housing, and an extension portion is provided on the lock block to abut against the switching pin; when the dial rotates in the locking direction, the switching pin drives the lock block to separate from the inner chip and the outer chip; when the dial rotates in the unlocking direction, the switching pin drives the lock block to abut against the inner chip and the outer chip.

[0014] The present invention is further configured such that the extension includes a first end and a second end located on both sides of the swing center of the lock block, so that when the first end abuts against the switching pin and the second end abuts against the switching pin, the lock block has opposite swing directions.

[0015] The present invention is further configured such that: the lock block is provided with a telescopic locking bead, and the dial is provided with two positioning grooves that cooperate with the telescopic locking bead, the two positioning grooves respectively corresponding to the positions when the lock block abuts or separates from the inner chip and the outer chip.

[0016] The present invention is further configured such that: the lock shell is provided with a travel limiting groove, and the inner and outer chips are provided with protruding locking blocks, the locking blocks being adapted to the limiting groove to constrain the rotational travel of the inner and outer chips.

[0017] The present invention is further configured such that: the dial wheel is provided with a flat bar hole, a flat bar extending to the outer handle is inserted through the flat bar hole, and the outer handle is provided with a rotatable unlocking element, the unlocking element can drive the flat bar to rotate, thereby driving the dial wheel to rotate.

[0018] In summary, this utility model has the following beneficial effects:

[0019] Compared with the prior art, this utility model uses the rotation of the dial wheel and the cooperation of the switching pin to realize the contact or separation of the lock block with the inner and outer chips. Its advantage is that through the optimized adjustment of the structure, the swing of the lock block does not rely on the inner or outer chip for driving, but on the cooperation of the dial wheel and the switching pin. In this way, the inner chip connected to the inner handle can be lifted and locked by the connecting pin, while the outer handle cannot be lifted and locked, thus avoiding accidental operation.

[0020] Meanwhile, this utility model also includes a blocking part and a limiting part. When the bolt is inside the lock housing, neither the inner nor outer handle can be reversed to lock. Reverse locking can only be performed after the door is closed and the bolt is extended. The advantages are: it prevents the door from automatically locking after closing due to accidental reverse lifting when the door is open; at the same time, it also prevents reverse lifting when the door is closed but not fully closed and the bolt is not extended, thus reminding the user that the door is not closed properly.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This embodiment discloses a one-way controlled anti-lock body structure, such as... Figure 1-9 As shown, the lock includes a lock housing 1, within which a retractable bolt 2 and a drive component 3 for driving the bolt 2 are provided. This lock structure is preferably applied in a magnetic lock body. The bolt 2 contains a magnet; when the bolt 2 reaches the position of the door lock box, it automatically extends under magnetic force. The drive component 3 is used to drive the bolt 2 to retract and to achieve reverse locking. In this embodiment, the drive component 3 includes a rotatable dial 301 and inner and outer chips 302 and 303 rotatably disposed on both sides of the dial 301 and respectively connected to the inner and outer handles. For details, please refer to... Figure 8 The dial 301 is equipped with a lever 12, and the latch 2 is equipped with a moving groove 13. The movement of the latch 2 is achieved through the cooperation of the lever 12 and the moving groove 13. In order to further realize the reverse lifting locking function, the dial 301 is equipped with a locking block 4 that can swing and abut or separate from both the inner chip 302 and the outer chip 303. The dial 301 is equipped with a connecting pin 5 that cooperates with the inner chip 302.

[0033] Reference Figure 2 and Figure 6 When the inner chip 302 or the outer chip 303 rotates in the unlocking direction, both the inner chip 302 and the outer chip 303 can drive the dial 301 to rotate in the unlocking direction through the abutting locking block 4; where the unlocking direction is the rotation direction when the inner and outer handles are pressed down, specifically... Figure 2The inner square chip 302 rotates clockwise. Figure 6 The outer chip 303 rotates counterclockwise; at this time, the locking block 4 is in contact with both the inner chip 302 and the outer chip 303, so the door can be opened by pressing down on both the inner and outer handles.

[0034] Reference Figure 3-5 When the inner chip 302 rotates in the locking direction, it drives the dial 301 to rotate in the locking direction via the connecting pin 5, causing the locking block 4 to separate from both the inner chip 302 and the outer chip 303. The locking direction is the direction of rotation when the inner handle is lifted (raised). Figure 3 In the middle, the inner chip 302 rotates counterclockwise. Due to the connecting pin 5, the inner chip 302 also drives the dial 302 to rotate counterclockwise, causing the locking block 4 to swing downwards, separating the locking block from the inner chip 302 and the outer chip 303. After resetting, the locking block 4 is in the correct position. Figure 4 and Figure 5 In this state, the outer chip 303 is spinning idly and cannot open the door; the door remains locked. However, the inner chip 302, due to the presence of connecting pin 5, can still drive the dial 301 to rotate. Figure 9 As shown, during the rotation of the dial 301, the locking block 4 will swing upward again and return to its original position. Figure 2 The state.

[0035] Through the design of the above structure, the inner handle of this utility model can be normally lifted to lock and pressed down to unlock, while the outer handle cannot be lifted to lock. When unlocking, it can be pressed down to unlock normally, but once locked, the door cannot be opened by using the outer handle. It is more suitable for the application scenario of interior doors and greatly avoids the inconvenience caused by the outer handle being able to be lifted to lock.

[0036] Furthermore, refer to Figure 2-3 The latch 2 is provided with a blocking part 201, and the inner chip 302 and the outer chip 303 are both provided with a limiting part 11. When the latch 2 retracts into the lock shell 1, the blocking part 201 abuts against the limiting part 11 to prevent the inner chip 302 and the outer chip 303 from rotating in the locking direction. Figure 2 In the middle, the locking tongue 2 is in the retracted state. At this time, the inner chip 201 obviously cannot rotate in the upward locking direction, and Figure 3 In the middle, the latch 2 extends, obviously the door is closed at this time. The latch 2 extends under the action of magnetic force. At this time, the positions of the blocking part 201 and the limiting part 11 are misaligned, and the inner chip 302 can rotate in the upward locking direction, thereby realizing locking.

[0037] This invention, through the design of the blocking part, 201, and the limiting part 11, prevents the inner handle from being reversed and locked when the latch 2 is not extended. This avoids premature locking due to accidental reverse lifting of the inner handle when the door is not closed, and the automatic locking that occurs when the door is closed and the latch 2 extends. The advantage of this invention is that locking only occurs after the door is fully closed and the latch extends, effectively preventing this problem. Furthermore, when the user closes the door but does not close it completely, the latch is not extended and reverse locking is also impossible, thus reminding the user that the door is not closed properly and improving security.

[0038] Furthermore, since the existing door has both left-opening and right-opening directions, to improve versatility, the connecting pin 5 and the dial 301 are detachable, as shown in the reference. Figure 8 Preferably, a simple threaded disassembly structure is used, with the connecting pin 5 and the dial wheel 301 being detachably configured. Both the inner square chip 302 and the outer square chip 303 have arc-shaped segments that abut against the connecting pin 5. When the inner square chip 302 rotates in the locking direction, the arc-shaped segment abuts against the connecting pin 5 and drives the dial wheel 301 to rotate in the locking direction. Correspondingly, when the inner square chip 302 rotates in the unlocking direction, an additional arc-shaped segment and connecting pin are needed to allow the inner square chip 302 to drive the dial wheel 301 to rotate even in the locked state. Therefore, preferably, the arc-shaped segment can be directly set as a notch 6. This way, regardless of which direction the inner square chip 302 rotates, it can drive the dial wheel 301 to rotate synchronously through the abutment between the notch 6 and the connecting pin 5, simplifying the structure. The distinction between inside and outside depends on the actual room. The connecting pin 5 is installed on the side that is inside the room, and the square chip on that side becomes the inner square chip. The square chip on the other side naturally becomes the outer square chip. The advantage of this utility model is that the inner square chip 302 can drive the dial wheel 301 through the connecting pin 5 and a notch 6, and the position of the lock block 4 can be changed by the dial wheel 301. Traditional reverse lifting locking structures rely on the square chip to directly drive similar lock block structures. However, since the room door has two forms, left opening and right opening, the direction of the lock body structure needs to be adjusted. Therefore, the inner and outer square chips must be made into a symmetrical structure so that after the lock body is reversed, the side that becomes the inner square chip can be adjusted in time. If the square chip were to directly drive the similar lock block structure to swing, and because the inner and outer square chip structures must be symmetrical, the outer handle would inevitably be able to achieve reverse lifting for locking, which is undesirable in this invention. Therefore, this invention changes its approach by relying on the inner square chip 302 to drive the dial wheel 301, and using the dial wheel 301 to swing the lock block 4 effectively avoids this problem. In this way, this invention, while satisfying the flexibility and versatility of left-opening and right-opening door adjustment, also achieves the goal of preventing the outer handle from being reverse-lifted for locking. This is something that traditional reverse-lift locking door locks cannot achieve.

[0039] Furthermore, a transmission play is provided between the notch and the connecting pin. Specifically, the size of the notch 6 is larger than the size of the connecting pin 5. Its function is to prevent the dial 301 from driving the inner chip 302 and the inner handle through the connecting pin 5 and the notch 6 when the dial 301 is driven directly by the unlocking element such as a key, thereby reducing resistance.

[0040] Furthermore, in order to achieve the aforementioned swinging of the lock block 4 by relying on the dial 301, this utility model has a switching pin 7 fixedly installed inside the lock housing 1, and the lock block 4 has an extension 401 that abuts and cooperates with the switching pin 7, as shown in the figure. Figure 3 When the dial 301 rotates in the locking direction, the switching pin 7 drives the locking block 4 to separate from the inner chip 302 and the outer chip 303; (refer to...) Figure 9 , Figure 4 and Figure 2 When the dial 301 rotates in the unlocking direction, the switching pin 7 drives the locking block 4 to abut against the inner chip 302 and the outer chip 303. The extension 401 includes a first end 4011 and a second end 4012 located on both sides of the swing center of the locking block 4, so that when the first end 4011 abuts against the switching pin 7 and the second end 4012 abuts against the switching pin 7, the locking block 4 has opposite swing directions. Specifically, since the first end 4011 and the second end 4012 are located on both sides of the swing center, when the first end 4011 is pushed upward by the switching pin 7, the locking block will swing downward to achieve separation; when the second end 4012 is pushed upward by the switching pin 7, the locking block will swing upward to achieve abutment. This utility model uses this structure to allow different ends of the locking block 4 to interact with the switching pin 7, so that the locking block 4, in conjunction with the rotation of the dial 301, has different swing directions.

[0041] Furthermore, to ensure the stability of the position of the locking block 4 after swinging, the locking block 4 is provided with a telescopic locking ball 402. The locking block 4 can be provided with a spring cavity. The telescopic locking ball 402 is simply made of a spring and a steel ball. The spring and the steel ball are installed in the spring cavity, and the steel ball part can be extended out of the locking block. At the same time, the dial 301 is provided with two positioning grooves 3011 that cooperate with the telescopic locking ball 402. The two positioning grooves 3011 correspond to the positions of the locking block 4 when it abuts or separates from the inner chip 302 and the outer chip 303, respectively.

[0042] Furthermore, to constrain the rotational travel of the inner chip 302, the outer chip 303, and the inner and outer handles, the lock housing 1 is provided with a travel limiting groove 9, and the inner chip 302 and the outer chip 303 are provided with protruding locking blocks 10, which are adapted to the limiting groove 9. The limiting groove 9 is as follows... Figure 7 If it is set to an arc segment, the card block 10 can be inserted into the limiting slot 9 to achieve the limit of the stroke.

[0043] Furthermore, to enable unlocking from the outside, the dial wheel 301 is provided with a flat bar hole 8, through which a flat bar (not shown in the figure) extends to the outer handle. The outer handle is provided with a rotatable unlocking element that drives the flat bar to rotate, thereby driving the dial wheel 301 to rotate. This unlocking element can be a key lock cylinder. When a key is inserted from the outside, it can directly drive the flat bar to rotate, thereby driving the dial wheel 301 to rotate, enabling the door to be unlocked with a key from the outside.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
