Description
Technical Field
[0001] The utility model relates to the technical field of locks, in particular to a lock tongue reversing device and a lock. Background Art
[0002] Door locks generally have an inclined tongue structure. During the assembly process of the inclined tongue structure, it needs to be switched and adjusted according to the opening and closing direction of the door body.
[0003] However, most of the existing door locks do not have the function of reversing the lock tongue. The direction of the oblique tongue needs to be determined during the process of assembling the lock on the door body. Once the lock is assembled on the door body, the lock and its internal oblique tongue structure need to be disassembled to adjust the reversal of the oblique tongue. The operation process is cumbersome, which not only affects the assembly efficiency of the lock and is not conducive to the rapid assembly and adjustment of the lock, but also may damage the matching accuracy between the lock itself, the door body and the door frame during the disassembly and adjustment of the lock, resulting in the door leaf being unable to be locked by the lock, or even unable to be opened and closed normally.

DETAILED DESCRIPTION
[0041] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0042] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0043] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0044] As can be seen from the background technology, locks generally have an inclined tongue structure, which is mainly used as the first lock of the lock on the door leaf. There are also other forms of inclined tongues in other lock structures, such as cross tongues, flip tongues, etc.
[0045] Taking the inclined tongue structure as an example, the inclined tongue structure is a relatively commonly used structural form in the lock tongue structure. Its main feature is that it facilitates the closing of the door body. The inclined tongue structure is located in the closing direction of the door body and generally forms a guiding inclined surface set at an angle to the door frame. When the door leaf is closed, the inclined tongue structure is against the door frame through the guiding inclined surface, so that the inclined tongue structure can be retracted into the lock under the action of the door frame, and when the door leaf is completely closed, the inclined tongue structure will be reset and inserted into the lock hole of the door frame, so that the door leaf cannot be reopened by directly pushing and pulling after closing. Its use process is relatively convenient, and it also has the relevant characteristics of simple structure and strong bearing capacity.
[0046] Since the inclined tongue structure has the above-mentioned functional characteristics, during the assembly process of the inclined tongue structure, it needs to be switched according to the opening and closing direction of the door body. Specifically, in order to adapt to the opening direction of the door body, namely, left opening, right opening, outward opening and inward opening, the inclined tongue needs to have two directions to adapt to the four door opening directions, namely, the guide bevel is located in front of or to the side of the inclined tongue. Generally speaking, the inclined tongue needs to rotate 180° around its own circumference to complete the switching adjustment of the guide bevel.
[0047] However, most of the existing door locks do not have the function of reversing the lock tongue. The direction of the oblique tongue needs to be determined during the process of assembling the lock on the door leaf. Once the lock is assembled on the door leaf, the lock and its internal oblique tongue structure need to be disassembled to adjust the reversal of the oblique tongue. The operation process is cumbersome, which not only affects the assembly efficiency of the lock and is not conducive to the rapid assembly and adjustment of the lock, but also may damage the matching accuracy between the lock itself, the door body and the door frame during the disassembly and adjustment of the lock, resulting in the door leaf being unable to be locked by the lock, or even unable to be opened and closed normally.
[0048] To this end, the present embodiment provides a lock tongue reversing device, which is specifically used in locks. The lock tongue reversing device locks and unlocks the lock tongue body 10 in the rotation direction through a locking component 20 that moves in the direction of gravity, thereby solving a series of problems caused by the difficulty in adjusting the lock tongue reversing.
[0049] Please refer to the attached Figure 1-Figure 6 The bolt reversing device includes a bolt body 10, which is configured to be movably arranged in the outer shell of the lock. In the application scenario of the lock, the bolt body 10 is arranged in the outer shell of the lock. It should be explained that the outer shell of the lock can also be referred to as a lock shell 30 in this embodiment. In this embodiment, the lock shell 30 serves as a supporting base for the lock product. Its main function is to provide corresponding installation positions and sufficient installation space for each device component included in the lock, so that each device component can be supported and fixed by it, and at the same time, a transmission matching relationship that meets the functional requirements of the lock can be achieved between them. The various device components are integrated into the space provided by the lock shell 30, which can effectively improve the compactness of the lock structure and the integrity of the product, so as to facilitate the installation and use of the lock. On the other hand, the lock shell 30 is also configured to provide a certain degree of protection for each device component assembled thereon, to prevent the lock from being easily damaged under the action of external forces, or to prevent external dust from directly contacting the mechanism components, thereby affecting the service life of the door lock.
[0050] To facilitate understanding of the solution, taking the state where the lock tongue body 10 is assembled in the lock shell 30 as an example, the lock tongue body 10 has at least two different sets of freedom of movement relative to the lock shell 30, so that the lock tongue body 10 located on the lock can provide normal locking function and reversing function at the same time.
[0051] Exemplarily, the bolt body 10 has the freedom of movement to telescope and self-reverse relative to the housing of the lock. It is understandable that the telescopic direction of the bolt body 10 includes opposite extension directions and retraction directions. In the case of the lock, the bolt body 10 can reach a position at least partially extending outside the lock housing 30 by moving in the extension direction. On the contrary, the bolt body 10 can reach a position retracted into the lock housing 30 by moving in the retraction direction, thereby achieving locking and unlocking of the lock. The rotation of the bolt body 10 is specifically achieved by rotating around its own rotation axis. The bolt body 10 is located on the lock housing 30 and completes the above-mentioned reversing adjustment by self-rotation.
[0052] It should be understood that in the application of the lock tongue reversing mechanism in lock products, the lock tongue body 10 can generally be driven back and forth in the extension and retraction direction by mechanical structures such as a handle, a lock core, and a motor that are also arranged on the lock shell 30. In addition, in some embodiments, the lock tongue body 10 can also be locked in a position state of at least partially extending out of the lock shell 30 and retracting into the lock shell 30 by a driving device such as a lock core and a motor. Since this part is not a technical means for solving the corresponding technical problem in this embodiment, this part of the solution will not be further elaborated here.
[0053] In the scenario where the lock tongue body 10 is specifically used in a lock, the user can set the lock tongue body 10 to be able to rotate in any position on the lock shell 30 according to the product requirements, design requirements, etc. of the lock, or set the lock tongue body 10 to be able to rotate in any position state relative to the lock shell 30 (for example, moving in any direction of the telescopic direction) before it can rotate.
[0054] According to the above-mentioned embodiments, in the case where the lock tongue body 10 is arranged to move relative to the lock housing 30 to a position where it can rotate, at least two specific ways of realizing the rotation are provided as follows:
[0055] 1. The bolt body 10 can move along the retracting direction until it is completely retracted into the lock housing 30 and then rotates;
[0056] Second, the bolt body 10 can move along the extension direction until it is completely extended out of the lock housing 30 and then rotates.
[0057] The above-mentioned lock tongue being fully retracted into or fully extended from the lock housing 30 specifically refers to the state in which the lock tongue body 10 is free from the restriction of the tongue hole 341 on the lock housing 30 and is entirely within the installation cavity 31 provided inside the lock housing 30, or is entirely outside the lock housing 30.
[0058] Through the above-mentioned implementation mode, the lock tongue body 10 is arranged to be able to rotate around its own rotation axis relative to the outer shell (lock shell 30) of the lock, so that the lock tongue body 10 can achieve reversing adjustment by self-rotation without being disassembled from the lock shell 30, that is, the lock tongue body 10 can achieve reversing adjustment. At the same time, since the reversing adjustment operation does not require the disassembly of the lock tongue body 10, the lock shell 30 does not need to be disassembled during the reversing adjustment process, thereby avoiding affecting the matching accuracy between material components, saving the assistance of disassembly tools and adjustment tools, simplifying the reversing procedures and steps, reducing the adjustment difficulty of the lock tongue body 10, and ultimately effectively extending the service life of the lock.
[0059] Please continue to refer to the attached Figure 1-Figure 3 On the basis of setting the lock tongue body 10 to be able to rotate relative to the lock shell 30 to meet the reversing adjustment requirements of the lock tongue body 10, in order to improve the ability of the lock tongue body 10 to maintain relative stability with the lock shell 30 in the corresponding position state, so that the lock tongue body 10 will not reverse for no reason in daily use, the lock tongue reversing device also includes a locking component 20. When the lock tongue reversing device is applied to the lock, the locking component 20 and the lock tongue body 10 can also be movably arranged on the lock shell (lock shell 30), and corresponding support is provided by the lock shell.
[0060] Furthermore, the locking member 20 can move between the locking position and the unlocking position under the action of gravity. For the time being, this embodiment does not have a strict limitation on the movement trajectory of the locking member 20 between the locking position and the unlocking position. Figure 1-Figure 3 Taking the two-dimensional plane shown as an example, the line between the locked position and the unlocked position, that is, the movement trajectory of the locking component 20 between the locked position and the unlocked position can be a straight line, an arc or a combination of the two. In addition, the locking component 20 can be a whole or partial linear motion or rotational motion.
[0061] The locking component 20 can specifically lock the lock tongue body 10 in the rotation direction according to the rotation mode of the lock tongue body 10 provided above by the following methods:
[0062] 1. When the lock tongue body 10 is configured to be able to rotate at any position on the lock housing 30, the locking member 20 in the locked position directly acts on the lock tongue body 10 to restrict the rotation of the lock tongue body 10;
[0063] Second, when the bolt body 10 is arranged to be required to move relative to the lock housing 30 to a position where it can rotate, the locking member 20 in the locked position restricts the bolt body 10 from moving to the position where it can rotate;
[0064] When the locking component 20 is in the unlocking position, the locking component 20 is separated from the lock tongue body 10, releasing the restriction on the lock tongue body 10, so that the lock tongue body 10 can rotate on its own, or the lock tongue body 10 can move to a position where it can rotate on its own.
[0065] It should be understood that in order to achieve the re-locking of the lock tongue body 10 after the reversal adjustment and enable it to maintain its stable state in the direction of rotation under a certain external force, the locking component 20 should be kept in the locked position when the lock is in use. That is to say, under normal circumstances, the gravity direction of the locking component 20 should be in a state of restricting the rotation of the lock tongue body 10 or restricting the lock tongue body 10 from moving to a position where it can rotate.
[0066] It can be understood from the above embodiment that although the locking component 20 can limit the rotation of the lock tongue body 10 in the locked position, it will not interfere with the movement of the lock tongue body 10 in the telescopic direction, ensuring that the lock tongue body 10 can normally provide its own function.
[0067] In summary, the bolt reversing device provided above sets the bolt body 10 to be capable of self-rotation, so that the bolt body 10 can still achieve reversal adjustment by self-rotation even when it is assembled in the lock. The user only needs to adjust the position of the lock to allow the locking component 20 to move between the locked position and the unlocked position under the action of gravity, thereby limiting the self-rotation of the bolt body 10 and allowing the bolt assembly to self-rotate or move to a position where it can self-rotate for self-reversal adjustment. The structure is simple and compact, and the switching process of the position state of the locking component 20 is simple and fast, without the need for manual operation by the user or auxiliary operation by external tools. In addition, the reversing process of the bolt body 10 does not require the disassembly of the outer shell of the lock, thereby avoiding affecting the matching accuracy between the material components, saving the use of disassembly tools and adjustment tools, simplifying the reversing procedures and steps, reducing the difficulty of reversing adjustment of the bolt body 10, and ultimately effectively extending the service life of the lock.
[0068] It can be seen from the above embodiments that the locking component 20 can adopt different movement modes according to the use requirements and design requirements of the lock. Please continue to refer to the attached Figure 1-Figure 3 In this embodiment, the locking component 20 adopts a swinging motion relative to the lock housing 30 under the action of gravity to achieve its switching between the locked position and the unlocked position.
[0069] Specifically, the first end of the locking component 20 is configured to be rotatably connected to the outer shell of the lock so that the other end of the locking component 20 can swing around the rotation axis of its first end. When the locking component 20 is actually assembled on the lock shell 30, the locking component 20 and the lock shell 30 can be rotatably connected by all rotating structures in the mechanical field of the prior art that enable two components to rotate relative to each other. This embodiment will not be described in detail here.
[0070] In the above embodiment, the locking member 20 adopts a rotational motion to ensure that at least one end of the locking member 20 maintains a stable connection with the lock housing 30, ensuring that the locking member 20 is stably installed in the lock housing, and the structure is more compact and reliable. At the same time, the swinging movement of one end of the locking member 20 relative to the other end saves more space than the movement of the locking member 20 as a whole in the lock housing, provides a wider installation space for other device components, and is also conducive to the integrated design and miniaturization design of the lock.
[0071] It is necessary to explain that, since the lock is usually in a state of normal use, Figure 1-Figure 3 The placement state shown, therefore, the locking position and the unlocking position in this embodiment need to be spaced apart along the up and down directions of the lock, and the locking position of the locking component 20 is located below the unlocking position, so that the locking component 20 can be maintained in the locking position under the action of gravity when the lock is in its normal use state. During the process of assembling the lock on the door leaf, the user can change the relative position of the locking position and the unlocking position of the locking component 20 by rotating the lock shell 30. When the user rotates the lock shell 30 to a level that is less than the level of the unlocking position, the locking component 20 can move from the locking position to the unlocking position under the action of gravity.
[0072] According to the above embodiment, it can be understood that, when the relative positions of the lock tongue body 10 and the lock shell 30 remain unchanged, when the locking component 20 is in the locked position, the second end of the locking component 20 is located at a position relatively close to the lock tongue body 10, so as to act on the lock tongue body 10 or block the lock tongue body 10; and when the locking component 20 is in the unlocked position, the locking component 20 as a whole is located at a position relatively far away from the lock tongue body 10, so as to avoid interference with the movement of the locking component 20 in all directions.
[0073] In one embodiment, according to the installation method of the locking member 20 on the lock housing 30, the horizontal height of the first end of the locking member 20 is between the horizontal heights of the locking position and the unlocking position. That is to say, taking the position state of the lock in the accompanying drawings as an example, when the locking member 20 is in the locking position, the locking member 20 is in a state of tilting from top to bottom from the first end to the second end, and when the locking member 20 is in the unlocking position, the locking member 20 is in a state of tilting from bottom to top from the first end to the second end. Of course, in other embodiments, the relative positional relationship between the first end of the locking member 20 and the locking position and the unlocking position may not be limited to this, as long as it can be ensured that the second end of the locking member 20 can reciprocate between the locking position close to the lock tongue body 10 and the unlocking position away from the lock tongue body 10 under the action of gravity, so this embodiment is not further limited in detail.
[0074] Continuing with the two limiting methods for the locking component 20 provided above, one of them is as follows: Figure 1-Figure 3 As shown, in the case where the locking component 20 is configured to limit the movement of the lock tongue body 10 to a rotatable position, when the locking component 20 is located in the locking position, the locking component 20 is at least partially located on the telescopic path of the lock tongue body 10, so as to constrain the extreme position of the lock tongue body 10 in the extension direction or the retraction direction through the locking component 20, thereby preventing the lock tongue body 10 from moving in the telescopic direction to the rotatable position state mentioned above that is out of the tongue hole 341.
[0075] Regarding the explanation of the telescopic path of the above-mentioned lock tongue body 10, as shown in Figure 1 As shown, the lock tongue body 10 is in the first position extending out of the lock housing 30 through the tongue hole 341. Figure 3 As shown, the bolt body 10 is in a position where the bolt body 10 is retracted into the lock housing 30 and can be self-rotating, and the telescopic path of the bolt body 10 is the movable path of the bolt body 10 between the first position and the position where the bolt body 10 can be self-rotating. When the locking member 20 is in the locked position, the locking member 20 is located on the telescopic path of the bolt body 10 from the first position to the self-rotating position, while ensuring that the locking member 20 is not in an improper position to affect the normal unlocking and locking of the lock, the bolt body 10 cannot move to the position where the bolt body 10 can be self-rotating.
[0076] It can be understood that in order to improve the integrity of the lock tongue reversing device in the application of the lock, the locking component 20 should also be arranged in the installation cavity 31 provided by the lock shell 30, and when the locking component 20 is arranged to constrain the lock tongue body 10 to the extreme position in the retraction direction, the locking component 20 can be arranged at the rear end of the lock tongue body 10, or by opening a rearward-facing abutting surface on the lock tongue body 10, so that the locking component 20 can limit the continued retraction of the lock tongue body 10 by abutting against the rear end face of the lock tongue assembly, or against the rearward-facing abutting surface formed by the lock tongue body 10; and when the locking component 20 is set to constrain the lock tongue body 10 to the extreme position in the extension direction, the lock tongue body 10 can be opened by opening a forward-facing abutting surface, so that the locking component 20 can limit the continued extension of the lock tongue body 10 by abutting against the forward-facing abutting surface formed by the lock tongue body 10. It should be noted that, in this embodiment, in order to ensure that the lock tongue body 10 can provide the locking function normally, the stroke of the locking component 20 to limit the lock tongue body 10 in the locked position should not be too short; when the locking component 20 is in the unlocked position, the locking component 20 is outside the telescopic path of the lock tongue body 10, and the lock tongue body 10 can move to the outside or inside of the lock shell 30 along the extension direction or the retraction direction under the operation of the user and break away from the restriction of the lock shell 30 until it can rotate, and after completing the rotation adjustment, move in the opposite direction to the position of its normal use state, so that the locking component 20 is reset to the locked position to re-limit the rotation of the lock tongue body 10.
[0077] Secondly, in the case where the locking component 20 is configured to limit the rotation of the bolt body 10, when the locking component 20 is in the locking position, the locking component 20 is at least partially located on one side of the bolt body 10 in the rotation direction, and forms a limiting fit with the bolt body 10 in the rotation direction. Specifically, the surface of the bolt body 10 configured to provide a portion for the locking component 20 to limit the action should be a non-circular surface, and the structure of the portion of the locking component 20 configured to act on the bolt body 10 is adapted to the non-circular surface, so that the rotation of the bolt body 10 in the state where the locking component 20 is in the locking position will cause interference between the non-circular surface and the locking component 20 and prevent the bolt body 10 from rotating; and when the locking component 20 is in the unlocking position, the locking component 20 releases the restriction on the movement of the bolt body 10 in the rotation direction, so that the bolt body 10 can be adjusted in rotation, and after the rotation adjustment, the locking component 20 is reset to the locking position to limit the rotation of the bolt body 10 again.
[0078] As an example based on any of the above embodiments, Figure 1-Figure 3 , Figure 6As shown, the locking component 20 is a plate-like structure, and the locking component 20 can be processed by sheet metal processing. The sheet metal can reduce the processing cost of the locking component 20 to a certain extent. Moreover, the locking component 20 with a plate-like structure has a simple structure and can also save the internal space of the lock shell 30, avoiding affecting the layout between the device components in the lock.
[0079] Similarly, the plate-shaped locking component 20 can achieve different movement modes and different restriction modes on the lock tongue body 10 by setting different forms of guiding structures between the locking component 20 and the lock housing 30 .
[0080] like Figure 6 As shown, in the case where the locking component 20 is configured to limit the movement of the lock tongue body 10 to a rotatable position, the plate-like structured locking component 20 includes a supporting end plate 21 and a limiting end plate 22, wherein the supporting end plate 21 is connected to one end of the limiting end plate 22 to cooperate to form an integral locking component 20, and since the supporting end plate 21 and the limiting end plate 22 are both plate components, the two can also be integrally processed and formed through sheet metal processing to improve the structural strength of the locking component 20, thereby improving the limiting ability of the lock tongue assembly.
[0081] Furthermore, in the scenario where the lock tongue reversing device is applied to a lock, the support end plate 21 is configured to be movably connected to the outer shell of the lock (lock shell 30), that is, the support end plate 21 needs to be provided with a corresponding movable matching structure between the lock shell 30 and the lock shell 30 according to the specific movement mode of the locking component 20 in the lock shell 30. For example, in the above-mentioned locking component 20 adopts a first end rotatably connected to the lock shell 30, and the second end can swing around the rotation axis of the first end. The support end plate 21 serves as the first end of the locking component 20 and is installed on the lock shell 30 through a rotatable connection structure. The limiting end plate 22 is located at one end of the supporting end plate 21 close to the lock tongue body 10, and is configured to limit or release the restriction on the lock tongue body 10 according to the current position state of the locking component 20. For example, in the above-mentioned implementation mode in which the first end of the locking component 20 is rotatably connected to the lock shell 30 and the second end can swing around the rotation axis of the first end, the limiting end plate 22 serves as the second end of the locking component 20, and realizes the movement between the locking position and the release position by swinging around the rotation axis of the supporting end plate 21, and according to the restriction method of the locking component 20 on the lock tongue body 10, in the locked position state, it is close to the lock tongue body 10 and acts on the lock tongue body 10, or is located on the movement path of the lock tongue body 10.
[0082] In the above-mentioned implementation mode in which the locking component 20 is a sheet metal part, since the structural strength of the locking component 20 with a plate-like structure is relatively weak, especially when the locking component 20 adopts a rotating manner to switch between the locking position and the unlocking position, the locking component 20 may be deformed or even damaged over time. Therefore, in the present embodiment, the limiting end plate 22 and the supporting end plate 21 are arranged at an angle to improve the structural strength of the locking component 20, and by adjusting the angle between the supporting end plate 21 and the limiting end plate 22, the relative angle between the limiting end plate 22 and the lock tongue body 10 can also be indirectly adjusted, thereby achieving the effect of enhancing the structural strength of the locking component 20 and increasing the contact surface between the limiting end plate 22 and the lock tongue body 10 in the limited state, thereby enhancing the strength and stability of the locking component 20 on the lock tongue body 10 in the restricted state.
[0083] In the above embodiment, the limiting end plate 22 and the supporting end plate 21 are arranged at an angle, which means that the relative positions of the limiting end plate 22 and the supporting end plate 21 are not parallel, but are placed or connected at a specific angle, which can be an acute angle, a right angle or an obtuse angle, depending on the actual application and design requirements. Figure 1-Figure 6 In the embodiment of the locking component 20 provided, the angle between the limiting end plate 22 and the supporting end plate 21 is an obtuse angle. In this way, in addition to improving the structural strength of the locking component 20, the locking component 20 can also expand the contact surface with the lock tongue body 10 through the limiting end plate 22, thereby improving its stability in the state of blocking the lock tongue body 10 from moving to the rotatable position.
[0084] Please refer to the attached Figure 1-Figure 5 The present embodiment further provides a lock, in which the lock tongue reversing device described in any of the above embodiments is applied. Specifically, the lock includes a lock shell 30. As can be seen from the above content, the lock shell 30 is designed to be a hollow shell structure in the present embodiment, so that the lock shell 30 can accommodate the mechanism components included in the lock through the installation cavity 31 formed therein, and each device component can be installed and matched with the lock when located in the installation cavity 31.
[0085] As an optional embodiment of the lock shell 30, in order to facilitate the assembly of the lock tongue reversing device and other device components in the lock, the lock shell 30 can be configured to be formed by the cooperation of the first shell 32 and the second shell 33, wherein the lock shell 30 can be made of different materials according to its specific application scenario and user requirements, such as metal, plastic, etc. And according to the manufacturing material adopted, the lock shell 30 can also be processed by different manufacturing processes. For example, when the lock shell 30 is made of metal, the first shell 32 and the second shell 33 can be processed by sheet metal (including but not limited to stamping, cutting, bending, etc.), milling, forging and other processes; and when the lock shell 30 is made of plastic material, the first shell 32 and the second shell 33 can be processed by injection molding, 3D printing, plastic casting and other processes. Similarly, in the specific embodiment of the lock tongue reversing device, the various components included therein can also be processed by different materials and different processes according to the actual needs of the product. The splicing of the first shell 32 and the second shell 33 can define a front side surface located at the front side of the lock and a rear side surface located at the rear side of the lock (as indicated by the "front" and "rear" directions of the arrows in the figure), and the rotation adjustment of the lock tongue body 10 on the lock shell 30 is used to adjust whether the side with the guide slope 11 is located closer to the above-mentioned front side or rear side. In some embodiments, the lock shell 30 is formed by the first shell 32 and the second shell 33, and it also includes a lock side strip 34 arranged on one side of the first shell 32 and the second shell 33. In the embodiment including the lock side strip 34, after the first shell 32 and the second shell 33 are spliced and formed, the outer side of the lock shell 30 (except the inner side and one side of the outer side) will form a mounting hole connected to the space of the internal mounting cavity 31 thereof, and the lock side strip 34 can be blocked on the mounting hole by being assembled on the first shell 32 and the second shell 33.
[0086] It can be understood from the above-mentioned embodiments that setting the lock shell 30 into a modular structure, in addition to facilitating the processing and production of the lock shell 30, can also reduce the difficulty of disassembly and assembly of the lock. During the assembly process of the lock, the mechanism components contained therein can be first assembled on the first shell 32 or the second shell 33, and then the first shell 32, the second shell 33, or the lock side strip 34 mentioned later can be spliced and matched to complete the assembly of the lock. At the same time, it can also meet the requirements of subsequent disassembly, inspection and maintenance of the lock. Of course, in order to meet this requirement, a detachable connection assembly method should be adopted between the lock modules, such as screw connection, snap connection, etc.
[0087] Please continue to refer to the attached Figure 5A tongue hole 341 communicating with the mounting cavity 31 is provided on one side of the lock shell 30. Based on the above embodiment, the tongue hole 341 is provided on the side of the lock shell 30 except the inner side and the outer side thereof. The tongue hole 341 is configured to provide a space for the lock tongue body 10 to move relative to the lock shell 30, so that the lock tongue body 10 can extend out or retract into the lock shell 30 through the tongue hole 341. Therefore, the tongue hole 341 is provided on the side of the lock shell 30 except the front side and the rear side thereof, so that the tongue hole 341 can be located on the side close to the door frame when the lock and the door body are closed, and can be located in a relative position to the lock hole (not shown) provided on the door frame.
[0088] Taking the above-mentioned implementation example in which the lock shell 30 is assembled by the first shell 32, the second shell 33 and the lock side strip 34, the lock side strip 34 is located on an outer side of the lock shell 30, and the tongue hole 341 is opened on the lock side strip 34, so as to form a positioning match with the lock tongue assembly during the assembly process of the lock side strip 34, and also make the matching accuracy between the lock tongue body 10 and the lock shell 30 easier to adjust.
[0089] Continuing with the above embodiment, the lock tongue body 10 and the locking component 20 are both located in the mounting cavity 31 and are movably connected to the lock housing 30, and the lock tongue body 10 can at least partially extend out of the lock housing 30 through the tongue hole 341 by moving in the telescopic direction, and the lock tongue body 10 can adjust its orientation on the lock housing 30 by self-rotation.
[0090] This embodiment provides two types of matching relationships between the lock tongue body 10 and the lock housing 30 according to the two situations in which the locking component 20 restricts the lock tongue body 10:
[0091] 1. When the locking member 20 is configured to limit the rotation of the bolt body 10, the bolt body 10 can rotate in the tongue hole 341. For example, in this embodiment, the cross-sectional shape of the bolt body 10 can be set to a circle, and correspondingly, the tongue hole 341 can also be set to a circle that is adapted to the cross-sectional shape of the bolt body 10. The size of the tongue hole 341 is set to be slightly larger than the cross-sectional size of the bolt body 10, so that the tongue hole 341 is kept in the form of being set around the outer periphery of the bolt body 10, and the hole wall of the tongue hole 341 is close enough to the outer periphery of the bolt body 10 to ensure that there is a gap between the two for telescopic movement. Through the above arrangement, after the user flips the lock so that the locking component 20 moves from the locked position to the unlocked position under the action of gravity and releases the lock tongue body 10, the lock tongue body 10 can be located in the tongue hole 341 under the action of external force to achieve self-rotation adjustment. After the lock tongue body 10 completes the self-rotation adjustment, the user can flip the lock again to reset the locking component 20 to the locked position in the direction of gravity, so that the locking component 20 acts on the lock tongue body 10 again, thereby completing the reversing operation of the lock tongue body 10.
[0092] Second, when the locking component 20 is configured to limit the movement of the lock tongue body 10 to the rotatable position, and the lock tongue body 10 is located in the tongue hole 341, the tongue hole 341 limits the rotation of the lock tongue body 10. In this embodiment, in addition to ensuring that the lock tongue body 10 can be provided with the freedom to move in the telescopic direction, it is also configured to limit the movement of the lock tongue body 10 in the rotation direction. Different from the above-mentioned embodiment in which the lock tongue body 10 can rotate in the tongue hole 341, illustratively, in this embodiment, the cross-sectional shape of the lock tongue body 10 can be set to a non-circular shape, and correspondingly, the tongue hole 341 is also set to a shape adapted to the cross-sectional shape of the lock tongue body 10, such as the attached Figure 5 As shown therein, the cross-sectional shape of the lock tongue body 10 is similar to a rectangle, and the tongue hole 341 is also configured as a rectangular structure that is compatible with the cross-sectional shape of the lock tongue body 10. In this way, when the lock tongue body 10 is in the tongue hole 341, the tongue hole 341 can restrict the freedom of movement of the lock tongue body 10 in the rotation direction, that is, the lock tongue body 10 cannot rotate in the tongue hole 341 when the lock is in normal use. With the above arrangement, after the user flips the lock so that the locking component 20 moves from the locked position to the unlocked position under the action of gravity and releases the lock tongue body 10, the lock tongue body 10 moves in the extending direction or the retracting direction according to the position where it can rotate to the position where it is separated from the tongue hole 341, such as moving in the extending direction to the outside of the lock shell 30, or moving in the retracting direction to the inside of the installation cavity 31, so that the lock tongue body 10 is separated from the restriction of the tongue hole 341 on its rotation direction, the lock tongue body 10 is further controlled under the action of external force to adjust its rotation. After the lock tongue body 10 completes the rotation adjustment, the lock tongue body 10 is reset to the tongue hole 341, so that the tongue hole 341 re-restricts the rotation of the lock tongue body 10. Finally, the user can flip the lock again to reset the locking component 20 to the locked position in the direction of gravity, so that the locking component 20 acts on the lock tongue body 10 again, thereby completing the reversing operation of the lock tongue body 10.
[0093] On the basis of any of the above embodiments, in order to improve the stability of the locking component 20 during the reciprocating motion between the locking position and the unlocking position, and when the locking component 20 is in the locking position and the unlocking position, as shown in FIG. Figure 1-Figure 6 As shown, a first guide portion 211 is provided on at least one side of the locking component 20 located in the installation cavity 31, and correspondingly, a second guide portion 35 is provided on the lock housing 30 located in the installation cavity 31. The locking component 20 is guided and cooperated with the lock housing 30 through the first guide portion 211 and the second guide portion 35, and the first guide portion 211 or the second guide portion 35 is extended along its activity direction according to the activity mode of the locking component 20.
[0094] Exemplarily, the first guide portion 211 and the second guide portion 35 may be a guide groove and a guide block structure of guide matching, or a guide rail and a guide block structure, or a guide hole and a guide column structure, etc.
[0095] As a further structural form of the above-mentioned guiding structure, Figure 1-Figure 6 As shown, the first guide portion 211 is a guide protrusion protruding from the locking component 20, and the second guide portion 35 is a guide groove opened in the lock housing 30. In view of the matching relationship between the guide block and the guide groove, this embodiment arranges the guide groove as a structural form extending along the movable direction of the locking component 20, so that the guide protrusion can be movably embedded in the guide groove along the direction in which the guide groove is opened.
[0096] Setting the first guide portion 211 on the locking component 20 as a guide protrusion is beneficial to the implementation of the locking component 20 being processed and formed by sheet metal processing. The locking component 20 and the first guide portion 211 are integrally formed, and there is no need to perform secondary processing on the locking component 20 after the locking component 20 is processed, which leads to an increase in processing costs and a decrease in efficiency.
[0097] Furthermore, a guide groove is arranged through the shell wall of the lock shell 30 so that the guide protrusion can be exposed to the outside of the lock shell 30 through the guide groove. In addition to reducing the difficulty of processing the guide groove on the lock shell 30, the exposed guide protrusion can also provide a corresponding operating space and position for manual operation of the locking component 20, so that the locking component 20 can be controlled by gravity. In addition to relying on gravity control, the user can apply an external force to the guide protrusion exposed in the guide groove by pressing a finger or a tool, thereby finally realizing the movement of the locking component 20 from the locked position to the unlocked position. In addition, the situation where the locking component 20 is stuck in the lock shell 30 can be solved by manual operation, which is also conducive to simplifying the structure of the lock tongue reversing device and improving the compactness of the product structure.
[0098] Please continue to refer to the attached Figure 1-Figure 3 When the locking component 20 is configured to limit the movement of the lock tongue body 10 to the rotatable position and the locking component 20 is located in the locked position, the present embodiment defines the locking component 20 as being at least partially located on the telescopic path at the rear end of the lock tongue body 10, and is used to constrain the lock tongue body 10 to an extreme position in the retraction direction.
[0099] Correspondingly, a guide rod 40 is provided at the rear end of the lock tongue body 10. The guide rod 40 is arranged in the installation cavity 31 and is fixedly connected to the lock tongue body 10. The guide rod 40 and the lock shell 30 slide together along the telescopic direction of the lock tongue body 10 to improve the cooperation stability between the guide rod 40 and the lock shell 30, so that the telescopic movement of the lock tongue body 10 is smoother and smoother. Furthermore, the lock housing 30 is located in the installation cavity 31 and is also provided with a support component 36. The guide rod 40 can be movably connected to the support component 36. An elastic reset member 50 is provided between the support component 36 and the lock tongue body 10. The elastic reset member 50 acts on the lock tongue body 10 so that the lock tongue body 10 is in a state where its front end extends out of the lock housing 30 through the tongue hole 341 under normal conditions. In addition, a stop portion 41 is provided at one end of the guide rod 40 away from the lock tongue body 10. The stop portion 41 can abut against the support component 36 to constrain the lock tongue body 10 to an extreme position in the extension direction. In this way, in the normal use state of the lock, the lock tongue body 10 is limited in the extreme position in the extension direction and the extreme position in the retraction direction by the locking component 20 and the support component 36 to prevent the lock tongue body 10 from detaching from the lock housing 30.
[0100] Similarly, when the locking component 20 is configured to constrain the lock tongue body 10 to an extreme position in the extending direction, the lock tongue body 10 can rotate to a position outside the lock housing 30, and correspondingly, the stop portion 41 on the guide rod 40 cooperates with the support component 36 to constrain the lock tongue body 10 to an extreme position in the retracting direction.
[0101] Please refer to the attached Figure 1-Figure 6 In the above-mentioned embodiment in which the locking component 20 is rotatably connected to the lock shell 30, the locking component 20 and the lock shell 30 can rotate relative to each other by means of a rotating protrusion 212 and a rotating hole 37 that rotates together. The rotating protrusion 212 can be convexly provided at the first end of the locking component 20, and the lock shell 30 is provided with a rotating hole 37 in the mounting cavity 31, so that the second end of the locking component 20 can swing around the rotation axis of the rotating protrusion 212. Conversely, a rotating hole 37 can be provided at the first end of the locking component 20, and the rotating protrusion 212 is convexly provided at the lock shell 30 in the mounting cavity 31 to achieve the cooperation between the two.
[0102] It is understandable that in the embodiment where the locking component 20 is processed by sheet metal technology, in order to reduce the processing difficulty of the locking component 20, it is preferred to process the rotating protrusion 212 on the locking component 20 and set the rotating hole through the lock shell 30.
[0103] Through the above-mentioned setting method, in an embodiment in which a guide protrusion and a guide groove are provided between the locking component 20 and the lock shell 30, the guide groove located on the lock shell 30 can be set to partially surround the swinging path of the locking component 20, so that when the second end of the locking component 20 swings around the rotation axis of its first end, the guide protrusion can be maintained in the guide groove and implement constraint guidance on the locking component 20.
[0104] In summary, by applying the lock tongue reversing device to the lock, the lock tongue in the lock can be prevented from disassembling and assembling the lock shell 30 and related device components during the reversing operation, which facilitates the rapid reversal of the lock tongue body 10 and reduces the user's operating difficulty, avoids the situation where the matching accuracy between the lock and the door leaf, and between the lock and the door frame is destroyed due to its disassembly, saves the use of disassembly tools and adjustment tools, simplifies the reversing procedures and steps, reduces the adjustment difficulty of the lock tongue body 10, and ultimately effectively extends the service life of the smart door lock and the door body.
