Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a lock body structure. Background Technology

[0002] In modern life, locks are crucial devices for protecting property and personal safety, and their technology is constantly evolving. U-locks, a common type of security lock, are widely used for locking and protecting glass doors. Traditional U-locks mostly use a single key structure for unlocking, which has several drawbacks. For example, users may face problems such as lost or stolen keys, or forgetting to bring their keys, causing inconvenience in daily life.

[0003] With the continuous advancement of technology, U-locks with fingerprint recognition or combination lock bodies have emerged to meet people's higher demands for convenience and security. These smart lock bodies, to some extent, solve the drawbacks of traditional key unlocking, providing users with more diverse unlocking methods. However, existing rotary combination lock bodies still reveal some problems in actual use. For example, after locking, users need to manually scramble the combination on the lock's dial, an operation that is not only cumbersome but also easily forgotten. If the combination is not scrambled in time, leakage can seriously threaten property security. Therefore, how to automatically change the numbers on the lock dial when locked, improving the security and ease of use of locks, has become an urgent problem to be solved in the current lock technology field.

[0004] Therefore, a lock body structure is needed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a lock body structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A lock body structure includes a U-shaped lock rod, a lock plate sleeved on the outside of the U-shaped lock rod, the lock plate including an outer shell, an inner shell having an installation groove inside the outer shell, an inner shell fixed to the installation groove by countersunk bolts, a turntable lock component fixed to the middle of the inner shell, a digital roller component externally connected to the turntable lock component, the digital roller component being rotatably connected to the inside of the inner shell, and a scrambling component for scrambling the digital roller component being rotatably connected to one side of the inner shell, the scrambling component including a sliding sleeve rod fixed to one side of the turntable lock component, a pressing shaft slidingly pressing one side of the sliding sleeve rod, the pressing shaft being rotatably connected to the inside of the inner shell, and multiple unidirectional fixed gears fixed to the outside of the pressing shaft, the fixed gears being rotatably connected to the turntable lock component.

[0007] Preferably, each locking hole surface of the outer shell is threaded with a rubber sleeve, the rubber sleeve is configured in a frustum shape, and a rubber ring is fixed to its inner wall.

[0008] Preferably, an annular groove is provided on one side of the inner shell, a sealing ring is fitted inside the annular groove, and a side wing is fixed to the outside of the sealing ring.

[0009] Preferably, the rotary lock includes a latch cylinder structure that is adapted to lock the U-shaped locking rod. The latch cylinder structure is connected and fixed to the sliding rod. The latch cylinder structure has a linear, equally spaced structure on its exterior, which is adapted to accommodate multiple combination rotating gears. The combination rotating gears are adapted to drive the rotary lock.

[0010] Preferably, there are two digital roller components, which are symmetrically connected to the inner housing. Each digital roller component includes a drive shaft rotatably connected to the inner housing. Multiple digital code wheels are rotatably connected to the outside of the drive shaft in a linear, equidistant structure. A drive gear that meshes with and is adapted to the turntable lock is fixed to one side of each digital code wheel.

[0011] Preferably, a limiting ring is fixedly connected to the outside of the extrusion shaft, and a spring is sleeved on the outside of the extrusion shaft at a position relative to the limiting ring and the sliding sleeve rod.

[0012] This utility model provides a lock body structure. Compared with the prior art, it has the following advantages:

[0013] 1. This lock body structure, through a uniquely designed scrambling mechanism, automatically scrambles the numbers on the digit rollers when the lock is locked. When the bolt and U-shaped locking rod complete the locking action, the turntable lock rotates, causing the attached sliding rod to move along with it. During this movement, the sliding rod slides and presses against the pressing shaft, causing it to rotate. Because multiple one-way fixed-gear gears are externally fixed to the pressing shaft and are connected to the turntable lock, the rotation of the pressing shaft further rotates the turntable lock, thus scrambling the numbers on the digit rollers. This automatic scrambling function effectively avoids the risk of password leakage due to users forgetting to manually scramble the code, greatly improving the security of the lock.

[0014] 2. The lock body structure, through the symmetrical design of the digital roller components and their meshing transmission with the rotary lock components, makes it more convenient for users to set and verify passwords, eliminating the need to distinguish between the front and back of the password numbers and improving the user experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those of ordinary skill in the art without creative effort are all within the scope of protection of the present utility model.

[0024] Please see Figures 1-7 This utility model provides a technical solution: a lock body structure, including a U-shaped lock rod 1, a lock plate 2 sleeved on the outside of the U-shaped lock rod 1, the lock plate 2 including an outer shell 3, an installation groove inside the outer shell 3, an inner shell 4 fixed in the installation groove by countersunk bolts, a turntable lock 5 fixed in the middle of the inner shell 4, a digital roller 6 externally connected to the turntable lock 5, the digital roller 6 being rotatably connected to the inside of the inner shell 4, and a scrambling component 7 for scrambling the digital roller 6 being rotatably connected to one side of the inner shell 4, the scrambling component 7 including a sliding sleeve rod 71 fixed to one side of the turntable lock 5, a pressing shaft 72 slidably pressing one side of the sliding sleeve rod 71, the pressing shaft 72 being rotatably connected to the inside of the inner shell 4, and multiple unidirectional fixed gears 73 fixed to the outside of the pressing shaft 72, the fixed gears 73 being rotatably connected to the turntable lock 5.

[0025] When the locking action is completed through the lock cylinder structure 51 and the U-shaped lock rod 1, the turntable lock 5 will rotate, causing the sliding sleeve rod 71 fixed to it to move together. During the movement, the sliding sleeve rod 71 will slide and press the pressing shaft 72, causing the pressing shaft 72 to rotate. Since multiple one-way drive fixed gears 73 are fixed to the outside of the pressing shaft 72, and the fixed gears 73 are connected to the turntable lock 5, when the pressing shaft 72 rotates, the fixed gears 73 will drive the turntable lock 5 to rotate further, thereby scrambling the numbers on the number roller 6. This effectively avoids the risk of password leakage caused by the user forgetting to manually scramble the password, greatly improving the security of the lock.

[0026] like Figure 3 and Figure 2 As shown, each lock hole surface of the outer shell 3 is threaded with a rubber sleeve 31. The rubber sleeve 31 is set in a frustum-shaped structure, and a rubber ring 32 is fixed to its inner wall.

[0027] At this point, it is worth noting that the rubber sleeve 31 and the rubber ring 32 can effectively improve the connection between the outer shell 3 and the U-shaped locking rod 1 during use. The rubber sleeve 31 and the rubber ring 32 can play a buffering role, reduce the damage to the lock body caused by external force collision, and also reduce the noise generated by the lock during opening and closing.

[0028] like Figure 4 and Figure 2 As shown, an annular groove is provided on one side of the inner shell 4, and a sealing ring 41 is fitted inside the annular groove. A side wing 42 is fixed to the outside of the sealing ring 41.

[0029] At this point, it is worth noting that the sealing ring 41 further enhances the sealing performance of the inner housing 4, preventing external impurities from entering and protecting the precision mechanical structure inside the inner housing 4. The side wing 42 increases the friction between the sealing ring 41 and the inner housing 4, making its installation more secure and less prone to falling off.

[0030] like Figure 5 and Figure 2 As shown, the turntable lock 5 includes a lock tongue and lock cylinder structure 51 that is adapted to lock the U-shaped lock rod 1. The lock tongue and lock cylinder structure 51 is connected and fixed to the sliding rod 71. The lock tongue and lock cylinder structure 51 has a linear and equally spaced structure on the outside and is adapted to multiple password rotating gears 52. The password rotating gears 52 are adapted to drive the turntable lock 5.

[0031] At this point, it is worth noting that the lock tongue cylinder structure 51 is responsible for locking and unlocking with the U-shaped lock bar 1. Its structural design has been carefully optimized and has high security and reliability. The password rotating gear 52 works in conjunction with the digital roller component 6 to realize the password setting and verification functions through transmission adaptation.

[0032] like Figure 6 andFigure 2 As shown, there are two digital roller components 6, which are symmetrically connected to the inner housing 4. Each digital roller component 6 includes a drive shaft 61 rotatably connected to the inner housing 4. Multiple digital password wheels 62 are rotatably connected to the outside of the drive shaft 61 in a linear and equally spaced structure. A drive gear 63 that meshes with and is adapted to the turntable lock component 5 is fixed to one side of each digital password wheel 62.

[0033] At this point, it is worth noting that the symmetrical design of the two digital rollers 6 makes the lock body more convenient and quick to set and operate the password. Users can easily set the password by rotating the digital password wheel 62. The meshing transmission between the drive gear 63 and the password rotation gear 52 ensures the accuracy and stability of the password setting and verification process.

[0034] like Figure 7 As shown in the figure, a limiting ring 74 is fixedly connected to the outside of the extrusion shaft 72, and a spring is sleeved on the outside of the extrusion shaft 72 at a position between the limiting ring 74 and the sliding sleeve rod 71.

[0035] At this point, it is worth noting that when the limiting ring 74 is in the sliding compression displacement between the sliding sleeve rod 71 and the extrusion shaft 72, the compression spring is elastically limited to reset the extrusion shaft 72 and prepare for the next random operation.

[0036] When working or using the device, if the user needs to unlock it, they first set the password to the correct combination by rotating the digital combination wheel 62 on the digital combination wheel 6.

[0037] At this time, the drive gear 63 on one side of the digital password wheel 62 meshes with the password rotating gear 52 on the turntable lock 5, driving the turntable lock 5 to rotate, causing the lock tongue and lock cylinder structure 51 to separate from the U-shaped lock rod 1, thus realizing the unlocking operation;

[0038] After the user finishes using the device, they insert the U-shaped locking rod 1 into the lock tongue and lock cylinder structure 51 to perform the locking operation. During the locking process, the turntable lock 5 rotates as the U-shaped locking rod 1 is inserted, causing the sliding sleeve rod 71, which is fixed to it, to move elastically with the lock groove of the U-shaped locking rod 1. The displaced sliding sleeve rod 71 slides and presses the pressing shaft 72, causing the pressing shaft 72 to rotate. The rotating pressing shaft 72 drives the externally fixed fixed gear 73 to drive the turntable lock 5 to rotate further under the unidirectional transmission characteristic, thereby scrambling the numbers on the number roller 6 and realizing the automatic scrambling function.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
