Description

Technical Field

[0001] This utility model relates to the field of lock manufacturing technology, and in particular to a lock body and a no-drill replacement lock for shop doors. Background Technology

[0002] Locks are devices that serve a sealing function, and can include the lock body, indoor and outdoor lock components, lock cylinder, key, and accessories. Drill-free replacement locks refer to the existing lock bodies already installed on aluminum alloy doors in the market. However, most shops are rented, and installing new smart locks (including mechanical and electronic smart locks) involves two core issues: first, landlords usually do not allow tenants to drill holes in the shop doors; second, even if the landlord allows additional drilling, the labor costs are high, and many certifications are involved. Therefore, removing the old lock and directly replacing it with a simple replacement lock that requires no drilling becomes the optimal choice.

[0003] With the development of technology, shops need keyless entry and exit or more intelligent smart locks to address the pain points of shop managers who need to leave early, either having to give the key to an employee to lock the door or rushing back to the shop in the middle of the night to lock it. Current shop metal door frame locks have an independent lock body structure with separate indoor and outdoor lock cylinders on both sides. This structure prevents the indoor and outdoor parts from being connected, and the three components of the lock body are not fixed on a single axis, making it impossible to achieve a keyless lock design or electronic lock gear-driven locking or unlocking. In such cases, a smart mechanical combination lock or smart electronic lock is needed to meet the requirements.

[0004] Please refer to Figure 1 This refers to a lock 100. Because it cannot be designed as a smart mechanical combination lock or a smart electronic lock, merchants usually need to replace lock 100 with a combination lock after obtaining the landlord's key to achieve keyless entry. When replacing lock 100 with a new lock, the new lock needs to have the same external dimensions as the lock body frame 1001 of lock 100, and also needs to be able to find the center point, torque, and angle for unlocking. (See also...) Figure 2 and Figure 3The lock 100 is used for installation on the door leaf 102. The door leaf 102 has a lock body hole 1021 and a lock cylinder hole 1023. The lock 100 includes a lock body frame 1001, a bolt 1002 and a lock cylinder 1003. The bolt 1002 is telescopically mounted on the lock body frame 1001 to engage or disengage with an opening on the door frame (not shown). The lock cylinder 1003 rotatably passes through the lock body frame 1001 to drive the bolt 1002 to extend or retract. The lock body frame 1001 is installed on the door leaf 102 by passing screws through screw holes thereon. It is obvious that the dimensions of the lock body hole 1021, the lock cylinder hole 1023, the bolt 1002, the lock body frame 1001, the position of the screw holes of the lock body frame 1001, the relative position of the bolt 1002 and the lock cylinder hole 1023, the existing stroke of the bolt 1002 and its position on the lock body are all fixed. When replacing the lock, it is necessary to ensure that the corresponding dimensions, positions and strokes of the new lock remain unchanged, otherwise it is impossible to install and the structure must be stable. Under the premise that these parameters cannot be changed, it is difficult to find a new transmission center point and complete the transmission structure in the existing extremely narrow space. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a lock body that can easily replace old locks and a no-drill replacement lock for shop doors.

[0006] To achieve the above objectives, this utility model provides a lock body for use with the outdoor and indoor components of a no-drill replacement lock for shop doors, as well as a lock ruler. The lock body includes: a housing for fixed installation within the installation space of the door; a latch movably disposed in the housing; a transmission sleeve for coupling with the lock ruler and receiving the drive of the lock ruler to rotate in a first direction to actuate a transmission lever, thereby driving the latch to retract; a first reset member; and a second reset member. When the driving force of the lock ruler is removed, the first reset member disposed on the transmission sleeve drives the transmission sleeve to reset in a second direction opposite to the first direction, and the latch extends and resets under the action of the second reset member connected to the latch.

[0007] Optionally, the transmission sleeve is disposed inside the housing and rotatably connected to both sides of the housing.

[0008] Optionally, the transmission sleeve includes a sleeve sleeve and a lever. The lever protrudes from one side of the outer circumference of the sleeve sleeve and swings within a certain range as the transmission sleeve rotates, so as to abut against the transmission lever or separate from the transmission lever.

[0009] Optionally, the transmission sleeve is used to couple and link with the lock ruler. The transmission sleeve is used to receive the driving force from either end of the lock ruler and rotate. One side of the transmission sleeve protrudes and moves the transmission lever, thereby driving the lock tongue to retract to open the door.

[0010] Optionally, the transmission sleeve is provided with a mating hole for non-rotatably coupling with the locking ruler, so that when the locking ruler is driven to rotate in the first direction, it can drive the transmission sleeve to rotate.

[0011] Optionally, the first reset member is an elastic member, one end of which is fixed relative to the transmission sleeve and the other end is fixed relative to the housing; the second reset member is an elastic member, one end of which abuts against the housing and the other end of which abuts against the locking tongue.

[0012] Optionally, the transmission sleeve and the transmission lever are separately disposed, with the transmission lever located on the rotation path of the transmission sleeve.

[0013] Optionally, the lock body further includes an auxiliary latch, which is movably disposed on the housing. The transmission sleeve is also used to drive the auxiliary latch to lock back when rotating in the first direction by moving the transmission lever. When the driving force of the lock lever is removed, and the first reset member disposed on the transmission sleeve drives the transmission sleeve to reset in a second direction opposite to the first direction, the auxiliary latch extends and resets under the action of the third reset member connected to the auxiliary latch.

[0014] This application also provides a drill-free replacement lock for a shop door, used for installation on a first component of the shop door to lock or unlock the first component relative to a second component, including:

[0015] An outdoor component, for mounting on the outside of the first component;

[0016] An interior component for installation inside the first component;

[0017] A locking lever, rotatably configured, passes through a mating hole in the transmission sleeve; and

[0018] The lock body is the aforementioned lock body, which is located between the indoor component and the outdoor component. The lock ruler extends inward from the outdoor component, passes through the lock body, and connects to the indoor component.

[0019] Optionally, the outdoor component includes a first external force driving member connected to one end of the locking lever, the first external force driving member being used to drive the locking lever to rotate so as to drive the transmission sleeve to rotate around the first direction; the indoor component includes a second external force driving member connected to the other end of the locking lever, the second external force driving member being used to drive the locking lever to rotate so as to drive the transmission sleeve to rotate around the first direction.

[0020] Optionally, the no-drill replacement lock for shop doors further includes an installation and fixing component, which includes an installation screw disposed on the indoor component; wherein, the outdoor component is provided with an installation post, and one of the installation screw and the installation post passes through the lock body and is connected to the other of the installation screw and the installation post; or, the outdoor component is provided with a screw hole, and the installation screw passes through the lock body and is connected to the screw hole.

[0021] In the lock body and the no-drill replacement lock for shop doors in the embodiments of this application, by setting a transmission sleeve coupled with the lock ruler, the relative position of the lock hole and the protruding position of the lock tongue, as well as the overall size of the lock body, can be easily designed. Furthermore, it is easy to find a center point, torque, and rotation angle that are highly consistent with the old lock. Therefore, the no-drill replacement lock for shop doors in this application can easily replace the old lock without having to make new holes in the door. Attached Figure Description

[0049] 80' Shop door lock replacement without drilling

[0050] 90. Door leaf Detailed Implementation

[0051] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0052] Unless otherwise specified in the embodiments, the techniques or conditions described in the literature in this field or in accordance with the product manual may be followed.

[0053] First Embodiment

[0054] Please refer to Figures 4 to 7 The first embodiment of this application provides a no-drill replacement lock 80 for shop doors, which is installed on a door leaf 90 to releasably lock an object (which may be a fixed door frame or another movable door leaf) relative to the door leaf 90. It is understood that the no-drill replacement lock 80 can also be installed on a fixed door frame, with the locked object being the door leaf. The no-drill replacement lock 80 of this embodiment includes an exterior component 11, an interior component 13, a lock body 15, and a lock scale 17. The exterior component 11 is installed on the outside of the door leaf 90 and includes a lock cylinder 110. The interior component 13 is installed on the inside of the door leaf 90. The lock body 15 is located between the exterior component 11 and the interior component 13. The outside and inside of the door leaf 90 are considered to be opposite sides. Generally, when the door leaf 90 is in use, the side of the door leaf 90 facing inwards is considered the inside, and the side of the door leaf 90 facing outwards is considered the outside. The lock body 15 includes a bolt 152, which can extend outward or retract into the door leaf 90 to lock or unlock. One end of the lock lever 17 is connected to the lock cylinder 110 of the outdoor component 11, and the lock lever 17 is rotatably mounted.

[0055] In this embodiment, the lock cylinder 110 of the outdoor component 11 can be a pin tumbler lock, a wafer lock, a magnetic lock, a smart card lock, a fingerprint lock, or other lock cylinder structures. This application does not limit the specific lock cylinder structure of the indoor component 11, as long as it can meet the usage requirements of the lock.

[0056] Specifically, the outdoor component 11 may further include a first external force driving member connected to one end of the lock cylinder 110 or lock ruler 17 of the outdoor component 11. The first external force driving member is used to drive the lock cylinder 110 or lock ruler 17 of the outdoor component 11, thereby causing the lock ruler 17 to rotate in a first direction, and then causing the bolt 152 of the lock body 15 to move and retract. Specifically, the first external force driving member may be a knob, handle, or motor sleeved on the lock cylinder 110 of the outdoor component 11. In this embodiment, the first external force driving member includes a key 111 for cooperating with the lock cylinder 110 and a motor 112 connected to the lock ruler 17 (see...). Figure 8 and Figure 9 The outdoor component 11 also includes a button section 113, which is electrically connected to the motor 112. The user can insert a matching key 111 into the lock cylinder 110's keyhole, and by rotating the key 111, drive the lock cylinder 110 to rotate, thereby causing the bolt 152 to extend or retract. The user can also input a password via the button section 113. When the password is correct, the motor 112 drives the lock ruler 17 to rotate, thereby causing the bolt 152 to retract. This achieves a keyless door lock structure design. In other words, the shop door lock 80 in this embodiment is an electronic combination lock, requiring no drilling. In this embodiment, the motor 112 is installed on the indoor component 13. Of course, the motor 112 can also be installed on the outdoor component 11 or the lock body 15. The motor 112 is electrically connected to the button section 113 via a conductive line 114. It is understandable that other input units such as fingerprint recognition units or face recognition units can be added to the outdoor component 11, or the button unit 113 can be replaced with other input units such as fingerprint recognition units or face recognition units to receive different decryption information.

[0057] Specifically, please refer to the following: Figure 8 , Figure 9 and Figure 10 The outdoor component 11 includes an outer main housing 116 and an outer cover plate 117. The outer main housing 116 has an opening on one side, and the outer cover plate 117 covers the opening of the outer main housing 116. The lock cylinder 110 is located on the outer main housing 116. The lock cylinder 110 has a protrusion 1163, and the outer cover plate 117 has a first through hole for the lock ruler 17 to pass through. One end of the lock ruler 17 has a lock ruler 171, which has a notch 173 to make the lock ruler 171 generally fan-shaped. The protrusion 1163 of the lock cylinder 110 is used to abut against the two end faces of the notch 173 of the lock ruler 171. When the lock cylinder 110 rotates, the protrusion 1163 on the lock cylinder 110 pushes the lock ruler 171 to rotate, that is, it drives the entire lock ruler 17 to rotate. The outer cover plate 117 is located on the side of the outer main housing 116 facing the lock body 15.

[0058] Specifically, the outer cover plate 117 can be fixedly connected to the outer main housing 116 by the first fastener 1173.

[0059] Specifically, the outer cover plate 117 has a first through hole 1175 for the conductive line 114 to pass through and extend into the outer main housing 116 to be electrically connected with the button part 113.

[0060] In this embodiment, please refer to Figure 8 , Figure 9 and Figure 11 The indoor component 13 does not have a lock cylinder. The lock ruler 17 on the outdoor component 11 passes through the lock body 15 and is directly and detachably fixedly connected to the indoor component 13.

[0061] Specifically, the interior component 13 may include a sleeve 131. The locking lever 17 passes through the housing 151 of the lock body 15 and is detachably and fixedly connected to the sleeve 131 of the interior component 13, thereby driving the locking lever 17 to rotate. Installation and disassembly are very convenient. Specifically, the sleeve 131 has a socket 1311 with a cross-section corresponding to the locking lever 17.

[0062] Of course, in other embodiments, the indoor component 13 may be provided with a lock cylinder that abuts against the lock ruler 17; the lock cylinder of the indoor component 13 may be a pin tumbler lock, a leaf lock, a magnetic lock, a smart card door lock, a fingerprint lock, or other lock cylinder structures. This application does not limit the specific lock cylinder structure of the indoor component 13, as long as it can meet the usage requirements of the lock. It is understood that since the lock ruler 17 is directly connected to the outdoor component 11 and the indoor component 13, the outdoor component 11 and the indoor component 13 can cooperate with each other, and the outdoor component 11 and the indoor component 13 may have different lock cylinder structures. For example, the outdoor component 11 may be a commonly used mechanical lock structure, while the indoor component 13 may be an electronic combination lock or an electronic fingerprint lock, etc. This configuration makes the opening and closing of the indoor component 13, which serves as the indoor lock, more convenient, realizing a keyless door lock structure design or electronic lock gear-driven locking or unlocking, thereby better adapting to the usage requirements of replacing locks on commercial aluminum alloy shop door frames.

[0063] Specifically, the interior component 13 may further include a second external force drive member 135 connected to the other end of the (lock cylinder) or lock lever 17 of the interior component 13. The second external force drive member 135 is used to drive the (lock cylinder) or lock lever 17, thereby causing the lock lever 17 to rotate in the first direction, and then causing the bolt 152 to retract. Specifically, the second external force drive member 135 may be a knob, handle, or motor sleeved on the lock cylinder or sleeve 131 of the interior component 13. The second external force drive member 135 has a hole with a cross-section corresponding to the lock lever 17 so that the second external force drive member 135 can drive the lock lever 17 to rotate.

[0064] Specifically, the interior component 13 includes an interior transmission assembly 137, through which the motor 112 is connected to the sleeve 131. When the motor 112 operates, it drives the sleeve 131 to rotate via the interior transmission assembly 137, thereby causing the locking tongue 152 to extend or retract. The output shaft of the motor 112 can be connected to the input end of the interior transmission assembly 137, and the sleeve 131 can be connected to the output end of the interior transmission assembly 137. Specifically, the interior transmission assembly 137 may include multiple gears 1371; it is understood that the interior transmission assembly 137 may also consist of other transmission structures such as worm gears.

[0065] Specifically, the interior component 13 also includes an inner main housing 139, an inner sub-housing 140, an inner sub-cover plate 141, and an inner cover plate 142. The inner sub-cover plate 141 covers the opening of the inner sub-housing 140. The inner sub-housing 140 and the inner sub-cover plate 141 are located inside the inner main housing 139, and the inner cover plate 142 covers the opening of the inner main housing 139. The interior transmission assembly 137 is located inside the inner sub-housing 140. The motor 112 is mounted outside the inner sub-housing 140, and the output shaft of the motor 112 extends into the inner sub-housing 140 to connect with the interior transmission assembly 137.

[0066] Specifically, the inner cover plate 142 has a second through hole 1421 for the conductive line 114 to pass through. The conductive line 114 extends from the top of the outer side of the inner sub-shell 140 along the outer surface of the inner sub-cover plate 141 and passes through the second through hole 1421.

[0067] In this embodiment, please refer to Figure 8 , Figure 9 , Figures 12 to 14 The lock body 15 includes a housing 151 fixedly installed in the door leaf 90, and a bolt 152 movably disposed within the housing 151. When driven, the bolt 152 can extend from the housing 151 along a first direction or retract into the housing 151 to achieve locking or unlocking. The housing 151 is installed at the edge of the door leaf 90. When the bolt 152 extends from the housing 151, it also extends from within the door leaf 90; when the bolt 152 retracts from the housing 151, it also retracts into within the door leaf 90. Specifically, the bolt 152 may be wedge-shaped.

[0068] Specifically, the lock body 15 also includes an auxiliary latch 153 movably disposed within the housing 151. When driven, the auxiliary latch 153 can extend from or retract into the housing 151 to achieve locking or unlocking. The housing 151 is mounted at the edge of the door leaf 90. When the auxiliary latch 153 extends from the housing 151, it also extends from the door leaf 90 along a first direction; when the auxiliary latch 153 retracts from the housing 151, it also retracts into the door leaf 90. Specifically, the auxiliary latch 153 can be wedge-shaped. It is understood that the auxiliary latch 153 can also be omitted, and locking the door leaf 90 can be achieved using only the latch 152.

[0069] Specifically, the housing 151 includes a first side plate 1511, a second side plate 1512, a first connecting plate 1513, a second connecting plate 1514, and a front panel 1515. The first side plate 1511 and the second side plate 1512 are arranged parallel to each other and spaced apart. The first connecting plate 1513 and the second connecting plate 1514 are respectively connected to the first side plate 1511 and the second side plate 1512 to connect the first side plate 1511 and the second side plate 1512 together. The front panel 1515 is located on the front side of the housing 151 and is used for fixed connection with the door leaf 90. The first connecting plate 1513 and the second connecting plate 1514 can be respectively located at both ends of the first side plate 1511 and the second side plate 1512. More specifically, both sides of the first connecting plate 1513 and the second connecting plate 1514 are provided with locking blocks 1516, and the first side plate 1511 and the second side plate 1512 are provided with locking holes 1517. The locking blocks 1516 are inserted into the locking holes 1517 to connect the first side plate 1511 and the second side plate 1512 with the first connecting plate 1513 and the second connecting plate 1514. The front panel 1515 is provided with openings for the bolt 152 and the auxiliary bolt 153 to extend out.

[0070] Specifically, the first side plate 1511 and the second side plate 1512 are each provided with a third through hole 1518 for the conductive line 114 to pass through.

[0071] Specifically, the housing 151 also includes a rear plate 15191 and a third connecting plate 15192. The two ends of the third connecting plate 15192 are respectively connected to the first side plate 1511 and the second side plate 1512, and the rear plate 15191 is connected to the third connecting plate 15192.

[0072] Specifically, the first side plate 1511 and / or the second side plate 1512 are provided with a first limiting groove 1520 and a second limiting groove 1521 extending in the direction of movement of the latch 152. The first side plate 1511 and / or the second side plate 1512 are also provided with a guide groove 1523.

[0073] In this embodiment, please refer to the following: Figures 8 to 11 The lock body 15 also includes a transmission sleeve 1553 and a transmission lever 1555. The lock scale 17 is movably disposed within the housing 151. The transmission sleeve 1553 is connected to the lock scale 17 and rotatably disposed within the lock body 15 to drive the transmission lever 1555 to translate, thereby moving the bolt 152 and the auxiliary bolt 153. The transmission sleeve 1553 is used to receive the driving force from either end of the lock scale 17 and rotate. One side of the transmission sleeve 1553 protrudes to actuate the transmission lever 1555, thereby driving the bolt 152 to retract and open the door. Specifically, the transmission sleeve 1553 is rotatably connected to both sides of the housing 151 (see...). Figure 16Specifically, the two ends of the transmission sleeve 1553 are rotatably connected to the first side plate 1511 and the second side plate 1512 of the housing 151, respectively. Under external force or key drive, the lock lever 17 can rotate, driving the transmission sleeve 1553 to rotate and moving the transmission lever 1555, thereby driving the latch 152 and the auxiliary latch 153 to move. The transmission sleeve 1553 is used to drive the latch 152 and the auxiliary latch 153 to retract when rotating around a first direction via the transmission lever 1555. Specifically, in this embodiment, the transmission sleeve 1553 and the transmission lever 1555 are separately arranged, and the transmission lever 1555 can be located on the rotation path of the transmission sleeve 1553, so that when the transmission sleeve 1553 rotates to the position of contacting the transmission lever 1555 and continues to rotate, it can drive the transmission lever 1555 to move. In the first embodiment, the locking ruler 17 is directly connected to the transmission sleeve 1553; in other embodiments, the locking ruler 17 can also be indirectly connected to the transmission sleeve 1553, for example, gear teeth are provided on the outer periphery of both the locking ruler 17 and the transmission sleeve 1553, and the locking ruler 17 and the transmission sleeve 1553 are connected by gear meshing.

[0074] Specifically, the lock body 15 also includes a first reset member 1556 disposed on the transmission sleeve 1553. The first reset member 1556 is configured to provide a restoring force to the transmission sleeve 1553 to drive the transmission sleeve 1553 to rotate about a second direction opposite to the first direction, thereby causing the lock lever 17 to rotate about the second direction and separating the transmission sleeve 1553 from the transmission lever 1555. When the driving force of the lock lever 17 is removed, the first reset member 1556 disposed on the transmission sleeve 1553 drives the transmission sleeve 1553 to reset along the second direction. Specifically, the first reset member 1556 can be an elastic element, such as a torsion spring. One end of the torsion spring is fixed relative to the transmission sleeve 1553, and the other end is fixed relative to the housing 151. The first reset member 1556 is provided with a pre-torque after installation. The housing 151 is also provided with a fixing post 1527, one end of the first reset member 1556 is fixed to the transmission sleeve 1553, and the other end is fixed to the fixing post 1527.

[0075] Specifically, the lock body 15 also includes a second reset member 1557 and a third reset member 1558. The second reset member 1557 is configured to provide a restoring force to the bolt 152 extending outward from the lock body 15, and the third reset member 1558 is configured to provide a restoring force to the auxiliary bolt 153 extending outward from the lock body 15. When the driving force of the lock lever 17 is removed, the bolt 152 extends and resets under the action of the second reset member 1557 connected to the bolt 152, and the auxiliary bolt 153 extends and resets under the action of the third reset member 1558 connected to the auxiliary bolt 153. The second reset member 1557 is used to drive the bolt 152 to move and extend out of the housing 151 of the lock body 15, and the third reset member 1558 is used to drive the auxiliary bolt 153 to extend out of the housing 151 of the lock body 15. Specifically, the second reset member 1557 and the third reset member 1558 can be elastic elements, such as telescopic springs. Of course, the second reset member 1557 and the third reset member 1558 can also be electromagnets, which generate magnetic force when energized to extend the latch 152. The second reset member 1557 and the third reset member 1558 are pre-compressed after installation. One end of the second reset member 1557 and the third reset member 1558 abuts against the rear plate 15191. When the second reset member 1557 and the third reset member 1558 are provided, the extension of the latch 152 and the auxiliary latch 153 does not require the second external force drive member 135 of the indoor component 13 and the first external force drive member of the outdoor component 11. When the external force acting on the latch 152 and the auxiliary latch 153 is removed (i.e., the first external force drive member and the second external force drive member 135 release the force on the lock plate 17), the restoring force of the second reset member 1557 and the third reset member 1558 can drive the latch 152 and the auxiliary latch 153 to automatically extend out of the housing 151 of the lock body 15.

[0076] Specifically, the latch 152 is provided with a first limiting block 1522 movably disposed within the first limiting groove 1520, and the auxiliary latch 153 is provided with a second limiting block 1531 movably disposed within the second limiting groove 1521. This limits the extension length (i.e., stroke) of the latch 152 and the auxiliary latch 153 in the first direction. By setting the positions of the first limiting groove 1520 and the second limiting groove 1521, the stroke of the latch 152 and the auxiliary latch 153 can be easily designed to meet the size requirements when replacing an old lock. At the same time, the first limiting groove 1520 and the second limiting groove 1521 can also serve as guide grooves to guide the movement of the latch 152 and the auxiliary latch 153.

[0077] Specifically, please refer to Figure 13The transmission sleeve 1553 may include a sleeve sleeve 15531 and a lever 15533 connected to the sleeve sleeve 15531. The sleeve sleeve 15531 may have a mating hole 15534 that is non-rotatably coupled to the locking lever 17. The locking lever 17 passes through the mating hole 15534, and the sleeve sleeve 15531 can rotate with the rotation of the locking lever 17. The lever 15533 is used to drive the locking tongue 152 with the rotation of the sleeve sleeve 15531. Furthermore, the lever 15533 protrudes from one side of the outer circumference of the sleeve sleeve 15531, and the lever 15533 swings within a certain range with the rotation of the transmission sleeve 15531 to abut against or separate from the transmission lever 1555. Specifically, the lever 15533 may be connected to the circumferential surface of the sleeve sleeve 15531. As an alternative, the lever 15533 can also extend radially outward from the end surface of the sleeve 15531, protruding from the side surface of the sleeve 15531. This also allows the lever 15533 to rotate with the sleeve 15531, thereby driving the locking tongue 152 to move. The housing 151 is also provided with a limiting post 1528 to limit the rotation range of the transmission sleeve 1553.

[0078] Preferably, the cross-sectional shape of the mating hole 15534 matches the cross-sectional shape of the locking ruler 17, i.e., they are a form fit. This invention does not limit the cross-sectional shape of the mating hole 15534 and the locking ruler 17; for example, the cross-sectional shape of the mating hole 15534 and the locking ruler 17 can be rectangular or square. Another example is that the cross-sectional shape of the mating hole 15534 and the locking ruler 17 can be cross-shaped, etc. It is understood that the mating hole 15534 and the locking ruler 17 can also be a non-form fit, as long as the inner wall of the lever sleeve 15531 has a limiting structure for limiting the clockwise and counterclockwise rotation of the locking ruler 17, the transmission connection between the locking ruler 17 and the lever sleeve 15531 (i.e., the transmission lever 1553) can be achieved.

[0079] For lever 15533, lever 15533 can be plate-shaped or sheet-shaped (see [link]). Figure 8 It can be in the form of a block or similar object, as long as it can rotate and the transmission lever 1555 can be moved.

[0080] Specifically, please refer to Figure 13The transmission lever 1555 includes a first part 15551, a second part 15552, and a third part 15553. The two ends of the second part 15552 are connected to the first part 15551 and the third part 15553, respectively. The first part 15551 faces the transmission sleeve 1553, and the third part 15553 faces the auxiliary locking tongue 153. The transmission lever 1555 is also connected to the locking tongue 152. More specifically, the first part 15551 and the third part 15553 extend towards both sides of the second part 15552, and each forms a certain angle with the second part 15552. A shaft hole 15555 is also provided on the transmission lever 15555, and the transmission lever 1555 is rotatably connected to the locking tongue via a connecting shaft 1561 inserted into the shaft hole 15555. A protrusion 1563 is also provided on the transmission lever 1555, which is movably accommodated within a guide groove 1523 of the housing 151. One end of the guide groove 1523 is provided with a recess 1525 recessed toward the transmission sleeve 1553, and the transmission lever 1555 can rotate relative to the locking tongue 152 around the connecting shaft 1561. When the locking tongue 152 is in the extended position, at least a portion of the protrusion 1563 can be located in the recess 1525. More specifically, the shaft hole 15555 can be formed at the connection between the second part 15552 and the third part 15553, and the protrusion 1563 can be provided at the connection between the first part 15551 and the second part 15552.

[0081] Specifically, an extension 1533 is provided on one side of the auxiliary locking tongue 153. The extension 1533 is provided in relation to the third part 15553 so that it contacts the third part 15553 when the transmission lever 1555 moves to the left, thereby being moved by the transmission lever 1555.

[0082] In this embodiment, the shop door no-drill replacement lock also includes an installation and fixing component 19. The middle part of the installation and fixing component 19 passes through the mounting hole 154 on the lock body 15, and the two ends of the installation and fixing component 19 are fixedly connected to the outdoor component 11 and the indoor component 13, respectively.

[0083] Specifically, the mounting and fixing assembly 19 may include mounting screws 130 disposed on the indoor component 13. The mounting screws 130 may have threaded rods 1301 for connection with the outdoor component 11, for threaded connection with the outdoor component 11 to achieve alignment and installation of the indoor component 13 and the outdoor component 11. The threaded rods 1301 are provided with external threads.

[0084] As a possible first embodiment of the mounting and fixing component 19 in this application, the mounting and fixing component 19 may further include a mounting post 1171 with one end disposed on the outdoor component 11, and the other end of the mounting post 1171 may pass through the mounting hole 154 of the lock body 15 and be threadedly connected to the mounting screw 130. The mounting post 1171 passes through the lock body 15 and is connected to the mounting screw 130, which makes the installation more secure and also avoids damage to the outdoor component 11 when the mounting screw 130 is directly installed on the outdoor component 11.

[0085] As a possible second embodiment of the mounting and fixing component 19 in this application, the mounting screw 130 on the indoor component 13 passes through the mounting hole 154 on the lock body 15 and the screw hole on the outdoor component 11 (in this case, the mounting post 1171 on the outdoor component 11 can be omitted, and the screw hole can be directly provided on the outdoor component 11), thereby axially connecting and fixing the outdoor component 11, the indoor component 13, and the lock body 15 to the door leaf 90. Of course, in some other embodiments, the outdoor component 11 may also be provided with a mounting post 1171, which has an internal thread. The mounting screw 130 passes through the lock body 15 and connects to the mounting post 1171, avoiding damage to the outdoor component 11 when the mounting screw 130 is directly installed on the outdoor component 11.

[0086] Understandably, the number of mounting screws 130 and mounting posts 1171 is equal. There is one mounting screw 130 and one mounting post 1171, and one mounting hole 154 on the lock body 15, thus reducing costs; alternatively, there are multiple mounting screws 130 and mounting posts 1171, with mounting holes 154 on the lock body 15 corresponding to the mounting screws 130 and mounting posts 1171 (the mounting holes 154 on the lock body 15 are aligned with the mounting screws 130 and mounting posts 1171 along the axial direction of the lock ruler 17), and multiple mounting holes 154 on the lock body 15. This not only facilitates better alignment of the outdoor component 11 and the indoor component 13, but also makes the connection between the outdoor component 11 and the indoor component 13 more secure.

[0087] When the user unlocks the door using the outdoor component 11, a first torque along the first direction can be applied to the lock ruler 17 via the key 111 (or, in other embodiments, via a knob or handle connected to the lock ruler 17, etc.) or via the motor 112 (i.e. via an electronic password). Under the action of the first torque (along the first direction), the lock ruler 17 drives the transmission sleeve 1553 to rotate along the first direction, thereby driving the transmission lever 1555 to move along the third direction, and thus pushing the bolt 152 to retract into the lock body 15 and disengage from the lock groove of the object being locked, thereby unlocking the door leaf 90 from the object being locked. When the user unlocks the door using the indoor component 13, the second external force drive 135 rotates along the first direction under the action of the second torque (along the first direction), thereby driving the lock ruler 17 to rotate along the first direction, and thus driving the transmission sleeve 1553 to rotate along the first direction. The bolt 152 retracts into the lock body 15 and disengages from the lock groove of the object to be locked, thereby unlocking the door leaf 90 from the object to be locked.

[0088] When locked, when the first external force driving member or the second external force driving member 335 removes the driving force on the driving lock ruler 17 in the first direction, the transmission sleeve 1553 will rotate and reset in the second direction opposite to the first direction under the action of the first reset member 1556, and disengage from the transmission lever 1555. The restoring force of the second reset member 1557 and the third reset member 1558 respectively push the lock tongue 152 and the auxiliary lock tongue 153 to extend out from the housing 151 of the lock body 15 and cooperate with the lock groove of the locked object, thereby realizing the locking of the door leaf 90 and the locked object.

[0089] In this embodiment of the lock body and the shop door no-drill replacement lock, the lock ruler transmission assembly, which consists of a transmission sleeve coupled with the lock ruler, allows for easy design of the relative position of the lock hole and the protruding position of the lock tongue, as well as the overall dimensions of the lock body. It also allows for easy re-finding of the center point, torque, and rotation angle that are highly consistent with the old lock. Therefore, the shop door no-drill replacement lock of this application can easily replace the old lock without having to drill new holes in the door.

[0090] Second Embodiment

[0091] Please refer to Figure 15 and Figure 16 The second embodiment of this application of the shop door no-drill replacement lock 80' includes an outdoor component 31, an indoor component 33, a lock body 15, and a lock ruler 17. The outdoor component 31 is installed on the outside of the door leaf. The indoor component 33 is installed on the inside of the door leaf (not shown). The outside and inside of the door leaf are opposite sides. Generally, when the door leaf is in use, the side facing inward is considered the inside, and the side facing outward is considered the outside. Please refer to... Figures 17 to 19 The structure of the lock body 15 and the mounting and fixing component 19 in the second embodiment is the same as that in the first embodiment, and will not be described again here.

[0092] In this embodiment, the outdoor component 31 does not have a lock cylinder. Of course, the outdoor component 31 may also include a lock cylinder, which can be a pin tumbler lock, a leaf lock, a magnetic lock, a smart card lock, a fingerprint lock, or other lock cylinder structures.

[0093] Specifically, the outdoor component 31 may also include a first external force driving member connected to the lock ruler 17. The first external force driving member is used to drive the lock ruler 17 to rotate in a first direction, thereby causing the bolt 152 of the lock body 15 to extend or retract. Specifically, the first external force driving member may be a knob, handle, or motor sleeved on the lock cylinder of the outdoor component 31. In this embodiment, the first external force driving member includes a knob 311 connected to the lock ruler 1511. The outdoor component 31 also includes a button part 313. When the correct password is entered on the button part 313, the knob 311 can be rotated. When the password is incorrect, the knob 311 cannot be rotated (this structure, where the knob can be rotated when the password is correct and cannot be rotated otherwise, is the same as the structure of a button-type mechanical combination lock disclosed in Chinese patent application CN 119860118A published on April 22, 2025, and will not be described again here). The user can rotate the knob 311, thereby causing the bolt 152 to extend or retract. This achieves a keyless door lock design. In other words, the drill-free replacement lock 80' for the shop door in this embodiment is a mechanical combination lock.

[0094] Specifically, the outdoor component 31 includes an outer main housing 316 and an outer cover plate 317. The outer main housing 316 has an opening on one side, and the outer cover plate 317 covers the opening of the outer main housing 316. The outer cover plate 317 has a first through hole for the locking ruler 17 to pass through. One end of the locking ruler 17 has a locking ruler 171, which has a notch 173 to make the locking ruler 171 generally fan-shaped. One end of the knob 311 is fixedly connected to a locking fastener 312, which has a protrusion 3121 for abutting against the two end faces of the notch 173 of the locking ruler 171. When the knob 311 is rotated, the protrusion 3121 pushes the locking ruler 171 to rotate, that is, drives the entire locking ruler 17 to rotate. The outer cover plate 317 is located on the side of the outer main housing 316 facing the lock body 15.

[0095] In this embodiment, the indoor component 33 does not have a lock cylinder. The lock ruler 17, which is connected to the outdoor component 31, passes through the lock body 15 and is directly and detachably fixedly connected to the indoor component 33.

[0096] Specifically, the interior component 33 may include a sleeve 331. The locking lever 17 passes through the housing 151 of the lock body 15 and is detachably and fixedly connected to the sleeve 331 of the interior component 33, thereby driving the locking lever 17 to rotate. Installation and disassembly are very convenient. Specifically, the sleeve 331 has a socket 3311 with a cross-section corresponding to the locking lever 17.

[0097] Of course, in other embodiments, the indoor component 33 may be provided with a lock cylinder that abuts against the lock ruler 17; the lock cylinder of the indoor component 33 may be a pin tumbler lock, a leaf lock, a magnetic lock, a smart card door lock, a fingerprint lock, etc. The present invention does not limit the specific lock cylinder structure of the indoor component 33, as long as it can meet the usage requirements of the lock. It is understood that since the lock ruler 17 directly connects the outdoor component 31 and the indoor component 33, the outdoor component 11 and the indoor component 33 can cooperate with each other, and the outdoor component 31 and the indoor component 33 may have different lock cylinder structures. For example, the outdoor component 31 may be a commonly used mechanical lock structure, and the indoor component 33 may be an electronic combination lock or an electronic fingerprint lock, etc. This setting makes the opening and closing of the indoor component 33, which serves as the indoor lock, more convenient, realizing a keyless door lock structure design or electronic lock gear-driven locking or unlocking, thereby better adapting to the usage requirements of replacing locks on commercial aluminum alloy shop door frames.

[0098] Specifically, in this embodiment, the indoor component 33 may further include a second external force driving member 335 connected to the lock lever 17. The second external force driving member 335 is used to drive the lock lever 17, thereby causing the lock lever 17 to rotate in the first direction, and thus causing the latch 152 to extend or retract. Specifically, the second external force driving member 335 may be a knob, handle, or motor, etc., indirectly or directly connected to the lock cylinder or sleeve 331 of the indoor component 33. The second external force driving member 335 has a hole with a cross-section corresponding to the lock lever 17 so that the second external force driving member 335 can drive the lock lever 17 to rotate.

[0099] Specifically, in this embodiment, the second external force driving member 335 is provided with a receiving groove 3351 and a lever 3353 adjacent to the receiving groove 3351. The sleeve 331 is eccentrically provided with a mating post 3313 that is received in the receiving groove 3351 and used to abut against the lever 3353. The second external force driving member 335 is rotatably configured to drive the lever 3353 to swing, thereby causing the mating post 3313 to rotate, which in turn causes the locking ruler 17 connected to the sleeve 331 to rotate, thereby driving the locking tongue 152 and the auxiliary locking tongue 153 to extend and retract.

[0100] More specifically, the second external force driving component 335 includes a wrench 3355 and a locking component 3356. The wrench 3355 includes a connecting part 33551 and an operating part 33553. The wrench 3355 can rotate about a rotation axis passing through the connecting part 33351. The locking component 3356 is fixedly connected to one side of the rotation axis of the wrench 3355, and the lever 3353 is disposed on the locking component 3356. Specifically, the locking component 3356 includes a locking block 33561 and a locking plate 33562. A locking groove 33555 is opened on one side of the rotation axis of the wrench 3355. The locking block 33561 is locked in the locking groove 33555. A part of the locking block 33561 extends out from the locking groove 33555 and engages with the locking plate 33562. The lever 3353 is disposed on the locking plate 33562.

[0101] Specifically, the interior component 33 also includes a base 339 and an inner cover plate 340. The base 339 is fixed relative to the housing 151 of the lock body 15 (specifically, it can be fixed to the door leaf 90). A wrench 3355 is rotatably connected to the base 339 about a rotation axis. The connecting part 33551 and the latching member 3356 of the wrench 3355 are accommodated inside the base 339. The inner cover plate 340 covers one side of the base 339 and covers a part of the sleeve 331. The other part of the sleeve 331 passes through the sleeve 331 and is connected to the lock ruler 17. Specifically, the wrench 3355 can be rotatably connected to the base 339 via a pivot 342.

[0102] When the user unlocks using the outdoor component 31, they can first enter a password on the button 313 to decrypt. After decryption, the first torque along the second direction can be applied to the lock ruler 17 through the key knob 311 (or, in other embodiments, through a handle or key connected to the lock ruler 17, etc.). Under the action of the first torque (along the first direction), the lock ruler 17 drives the transmission sleeve 1553 to rotate along the first direction, thereby driving the transmission lever 1555 to move along the third direction, and thus pushing the lock tongue 152 to retract into the lock body 15 and disengage from the lock groove of the object to be locked, thereby unlocking the door leaf 90 from the object to be locked. When the user unlocks using the indoor component 33, the second external force drive 335 rotates along the second direction under the action of the second torque (along the first direction), thereby driving the lock ruler 17 to rotate along the first direction, and thus driving the transmission sleeve 1553 to rotate along the first direction. The lock tongue 152 retracts into the lock body 15 and disengages from the lock groove of the object to be locked, thereby unlocking the door leaf 90 from the object to be locked.

[0103] When locking, the user only needs to release the first external force driving member or the second external force driving member 335, so that the driving force provided by the lock ruler 17 to the transmission sleeve 1553 is removed. The transmission sleeve 1553 will rotate in the second direction and reset under the action of the first reset member 1556, and disengage from the transmission lever 1555. The second reset member 1557 and the third reset member 1558 respectively push the lock tongue 152 and the auxiliary lock tongue 153 to extend out from the housing 151 of the lock body 15 and cooperate with the lock groove of the locked object, thereby realizing the locking of the door leaf 90 and the locked object.

[0104] It is understood that the structural form of the first external force driving member and the second external force driving member 335 in the first embodiment and the second embodiment can be adjusted as needed (it can be a knob, handle, motor, key, etc.), as long as it can drive the lock ruler 17 to rotate to drive the lock tongue 152 and / or the auxiliary lock tongue 153 to move.

[0105] Third Embodiment

[0106] The third embodiment of this application also provides a lock body. The structure of the lock body in this embodiment is the same as that of the lock body 15 in the first embodiment, and will not be described again here.

[0107] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
