Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a lock with an integrated lock cylinder. Background Technology

[0002] The lock cylinder is the core opening and closing component of a lock. Current locks generally employ a distributed lock cylinder structure, where the lock cylinder body and its associated parts are separate. During the lock assembly process, these individual parts can only be installed and aligned one by one inside the lock seat; the entire lock cylinder cannot be pre-assembled before being assembled onto the lock seat. This assembly method involves numerous steps and a complex process, making it unsuitable for mass production on assembly lines and resulting in low production efficiency. Furthermore, the lock cylinder's associated parts are small and numerous, making them prone to omissions, misassemblies, and reverse installations during assembly, increasing the assembly defect rate and raising production rework costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a lock with an integrated lock cylinder. The integrated lock cylinder can be pre-assembled as an independent module and directly assembled into the lock seat without the need for separate parts, which greatly improves the assembly efficiency of the lock.

[0004] To achieve the above objectives, this utility model provides a lock with an integrated lock cylinder, adopting the following technical solution: A lock with an integrated lock cylinder includes an integrated lock cylinder, a lock base, a lock rod, and a fixing component. The integrated lock cylinder includes a lock cylinder body, a lock cylinder sleeve, and a lock cylinder shell. The two ends of the lock cylinder body are a latch end and a keyhole end for key insertion, respectively. The latch end is equipped with a lock tongue. When the matching key is inserted into the keyhole end and drives the lock cylinder body to rotate, the lock tongue rotates synchronously with the lock cylinder body. The lock cylinder sleeve has first notches or holes on both sides for fasteners to pass through. The lock cylinder shell is located outside the lock cylinder sleeve. The lock cylinder shell has first through holes on both sides, and the first through holes on both sides are arranged opposite to the first notches or holes. The lock cylinder body is housed inside the lock cylinder sleeve and can rotate relative to the lock cylinder sleeve. The lock seat has a second through hole. The lock cylinder shell has a snap-fit ​​strip. The lock seat has a snap-fit ​​groove that engages with the lock cylinder shell, so that the first through hole and the second through hole are aligned with each other. The fastener passes through the second through hole and extends sequentially through the first through hole on one side of the lock cylinder shell, through the first notch or hole in the lock cylinder sleeve, and out through the first through hole on the other side of the lock cylinder shell, thereby fixing the integrated lock cylinder as a whole inside the lock seat. The lock cylinder body drives the lock tongue to cooperate with the lock seat to lock and limit the lock rod.

[0005] By adopting the above technical solution, this lock combines the lock cylinder body, lock cylinder sleeve, and lock cylinder shell into an integrated modular lock cylinder component, which can be pre-assembled, simplifying the lock assembly process and improving assembly efficiency. The lock cylinder shell is pre-positioned by the snap-fit ​​strip and the lock seat slot, ensuring precise alignment of the first and second through holes, reducing the difficulty of inserting the fasteners, and the lock cylinder body can rotate independently inside the lock cylinder sleeve. The integrated lock cylinder is embedded inside the lock seat, with a compact structure that effectively protects the internal components and reduces external prying points, improving the lock's anti-theft performance. When the lock cylinder malfunctions, it can be removed and replaced entirely by disassembling the fasteners, without disassembling the lock seat, making subsequent maintenance and replacement more convenient.

[0006] The present invention is further configured such that: a groove is provided above the tongue end, and a second notch is provided on one side of the groove; a base adapted to the groove is provided at the bottom of the lock tongue, the base is assembled in the groove, and a protrusion is provided on the base corresponding to the position of the second notch, the protrusion engaging with the second notch, and the lock tongue rotating synchronously with the lock cylinder by means of the protrusion.

[0007] By adopting the above technical solution, the base that accommodates the bolt in the groove is used for positioning. The protrusion and the second notch are engaged with each other to transmit torque, ensuring that the bolt and the lock cylinder rotate synchronously and that the torque transmission is stable and reliable. The bolt is easy to disassemble and assemble, can be replaced individually, and can be adapted to different locks, making it highly versatile. The base is embedded in the groove, which provides better stability under force and effectively prevents the bolt from loosening and slipping during operation, thus improving the reliability of the lock.

[0008] The present invention is further configured such that: the outer shell extends a limiting section at one end of the locking tongue, and the two ends of the limiting section are a first abutting end and a second abutting end, respectively; the protrusion extends out a second notch, and can abut and limit the locking tongue with the first abutting end and the second abutting end, respectively.

[0009] By adopting the above technical solution, the outer shell extends into a limiting section. The first and second abutting ends of the limiting section form a rotation limit on the protrusion that rotates with the bolt, which can limit the rotation angle of the bolt and prevent the bolt from over-rotating and jamming or over-travel. The limiting structure is integrated into the outer shell, eliminating the need for additional limiting parts, resulting in a simple and compact structure. At the same time, the protrusion enables limiting contact, the force position is clear, the limiting is reliable, and the stability of the lock cylinder operation is improved.

[0010] The present invention is further configured such that: an annular step is provided circumferentially at the keyhole end, and a flange is provided on the outside of the groove at the tongue end of the lock cylinder; the lock cylinder sleeve is snapped between the annular step and the flange, and a gap is left between the lock cylinder sleeve and the annular step and the flange.

[0011] By adopting the above technical solution, the lock cylinder sleeve is axially positioned between the annular step and the flange, preventing the lock cylinder sleeve from moving axially along the lock cylinder body. A gap is reserved between the lock cylinder sleeve and the annular step and the flange to avoid frictional interference between the lock cylinder body and the lock cylinder sleeve when the lock cylinder body rotates, reduce rotational resistance, and ensure smooth rotation of the lock cylinder body. At the same time, the step and the flange form end limits, making assembly positioning intuitive and simple, and improving assembly efficiency.

[0012] The present invention is further configured such that: an outer shell is provided on the outside of the lock seat, and a through cavity is opened at the bottom of the outer shell corresponding to the keyhole end. Two dustproof sheets and an elastic element are assembled in the through cavity; one end of the elastic element abuts against the side wall of the through cavity, and the other end abuts against the end of the dustproof sheet, thereby driving the two dustproof sheets to fit together and cover the keyhole end.

[0013] By adopting the above technical solution, an outer shell is added to the outside of the lock base. A pair of dustproof plates and elastic elements are installed in the cavity at the bottom of the outer shell. The elastic elements continuously push the two dustproof plates to fit together to cover the keyhole end. When no key is inserted, the keyhole is blocked, preventing dust, debris and moisture from entering the lock cylinder and avoiding the lock cylinder from accumulating dust, getting stuck, rusting and failing. When the key is inserted, it can push open the dustproof plates to complete the unlocking operation. After the key is pulled out, the dustproof plates automatically close under the action of the elastic elements, without the need for manual reset. The dustproof effect is continuous and stable, effectively extending the service life of the lock cylinder.

[0014] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0018] Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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 a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] As attached Figure 1-8 As shown, a lock with an integrated lock cylinder includes an integrated lock cylinder 1, a lock base 5, a lock rod 9, and a fixing member 6. The integrated lock cylinder 1 includes a lock cylinder body 2, a lock cylinder sleeve 3, and a lock cylinder shell 4. The two ends of the lock cylinder body 2 are a latch end 21 and a keyhole end 22 for inserting a key, respectively. The latch end 21 is equipped with a bolt 7. When the matching key is inserted into the keyhole end 22 and drives the lock cylinder body 2 to rotate, the bolt 7 rotates synchronously with the lock cylinder body 2.

[0021] The keyhole end 22 is provided with an annular step 221 around its circumference, and the latch end 21 of the lock cylinder body 2 is provided with a flange 213 on the outside of the groove 211; the lock cylinder sleeve 3 is snapped between the annular step 221 and the flange 213 to form an axial limit, which can prevent the lock cylinder sleeve 3 from axially moving; there is a gap between the lock cylinder sleeve 3 and the annular step 221 and the flange 213, which can also eliminate frictional interference when the lock cylinder body 2 rotates, reduce rotational resistance, and allow the lock cylinder body 2 to rotate flexibly inside the lock cylinder sleeve 3.

[0022] The latch end 21 has a groove 211 above it, and a second notch 212 is provided on one side of the groove 211. The bottom of the latch 7 has a base 71 that matches the groove 211. The base 71 is fitted into the groove 211. The base 71 has a protrusion 711 at the position corresponding to the second notch 212. The protrusion 711 and the second notch 212 are engaged and cooperated. The latch 7 rotates synchronously with the lock cylinder 2 with the help of the protrusion 711. The base 71 is embedded in the groove 211, which makes the force more stable and can prevent the latch 7 from loosening and slipping during operation. The latch 7 is detachable and easy to replace. It can be adapted to different locks and has strong versatility.

[0023] The lock cylinder shell 4 extends a limiting section 43 at one end of the bolt 7. The two ends of the limiting section 43 are a first abutment end 431 and a second abutment end 432, respectively. The protrusion 711 extends a second notch 212 and can abut against the first abutment end 431 and the second abutment end 432 respectively as the bolt 7 rotates, thereby limiting the rotation angle of the bolt 7 and preventing the bolt 7 from overtraveling and getting stuck. This limiting structure is integrally formed on the lock cylinder shell 4, without the need for additional parts. The structure is compact, the limiting is reliable, and the stability of the lock cylinder operation is improved.

[0024] The lock cylinder sleeve 3 has first notches 31 or holes on both sides for the fasteners 6 to pass through. The lock cylinder shell 4 is located outside the lock cylinder sleeve 3. The lock cylinder shell 4 has first through holes 41 on both sides, and the first through holes 41 on both sides are opposite to the first notches 31 or holes. The lock cylinder body 2 is received inside the lock cylinder sleeve 3 and can rotate relative to the lock cylinder sleeve 3. The lock seat 5 has a second through hole 51. The lock cylinder shell 4 has a snap-fit ​​strip 42. The lock seat 5 has a snap-fit ​​groove 52 for engaging and positioning with the lock cylinder shell 4, so that... The first through hole 41 and the second through hole 51 are aligned with each other. When it needs to be assembled with the lock, the fixing member 6 passes through the second through hole 51 and extends sequentially through the first through hole 41 on one side of the lock cylinder shell 4, through the first notch 31 or hole in the lock cylinder sleeve 3, and then out through the first through hole 41 on the other side of the lock cylinder shell 4, thereby fixing the entire integrated lock cylinder 1 inside the lock seat 5. The lock cylinder shell 4 is further locked and limited by the fixing member 6 to prevent the lock cylinder sleeve 3 from rotating with the lock cylinder body 2, so that the locking is stable and reliable. When the lock cylinder body 2 rotates, it drives the lock tongue 7 to rotate together. The lock tongue 7 cooperates with the lock seat 5 to lock and limit the lock rod 9. The overall structure is compact and the operation is stable. The lock cylinder body 2, lock cylinder sleeve 3 and lock cylinder shell 4 are integrated into a modular whole. Its structure has a high degree of integration and strong versatility. It can be pre-assembled as an independent module and directly assembled into the lock seat 5 without additional scattered parts, reducing the assembly difficulty and improving the assembly efficiency.

[0025] The lock base 5 has an outer shell 8 on its outer side. A cavity 81 is formed at the bottom of the outer shell 8 corresponding to the keyhole end 22. Two opposing dustproof plates 82 and an elastic element 83 are installed within the cavity 81. One end of the elastic element 83 abuts against the side wall of the cavity 81, and the other end abuts against the end of the dustproof plate 82, causing the two dustproof plates 82 to fit together and cover the keyhole end 22. When no key is inserted, it can block the keyhole, preventing dust, debris, and moisture from entering the lock cylinder, thus avoiding dust accumulation, jamming, rust, and malfunction. When the key is inserted, it pushes open the dustproof plate 82 to complete the unlocking operation. After the key is removed, the dustproof plate 82 automatically closes under the action of the elastic element 83, requiring no manual reset. The dustproof effect is continuous and stable, effectively extending the service life of the lock cylinder.

[0026] It should be noted that the locking structure formed between the lock seat 5 and the lock tongue 7 is existing technology. When the lock tongue 7 rotates, it drives the snap-fit ​​component inside the lock seat 5 to engage with the lock rod 9, thereby completing the locking action. The improvement of this utility model does not lie in the locking relationship between the lock tongue 7 and the lock rod 9, so this locking structure will not be described in detail in this article.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
