[0011] In order to further solve the technical problem to be solved by the utility model, the utility model provides a sliding lock protector, wherein a handle is connected to the sliding cover.

[0012] In order to further solve the technical problem to be solved by the utility model, in a sliding lock protector provided by the utility model, a damping structure is provided between the base and the sliding cover.

[0013] In order to further solve the technical problem to be solved by the utility model, the utility model provides a sliding lock guard, in which the damping structure includes a plurality of accommodating holes arranged at the lower part of the outer side surface of the base, marbles arranged in the accommodating holes and capable of extending outward to press against the inner side surface of the sliding cover, and a third reset elastic member arranged between the marbles and the accommodating holes and pressing the marbles outward.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1. The utility model adopts a clutch-type locking structure, and the clutch of the inner pin and the outer socket can realize the locking and unlocking of the sliding cover. Among them, the inner pin can be automatically connected to the outer socket under the action of the elastic reset member, and the separation of the inner pin and the outer socket only requires manually pressing the outer pin inward. The design of this sliding lock guard is extremely user-friendly. It not only has a simple structure, but also simplifies the operation procedure. Unlocking can be completed by simple pressing and sliding actions, reducing the inconvenience in use. At the same time, the structure also takes into account the appearance. The sliding cover can hide the keyhole to reduce the abruptness. In addition, due to the simplicity of the structure, its manufacturing cost is relatively low.

[0022] 2. In the utility model, the handle connected to the sliding cover not only improves the convenience of the user when operating the sliding cover, but also acts as a door handle, thereby achieving multifunctionality. The existence of the handle makes it unnecessary to install a separate door handle. This dual-purpose design reduces the number of accessories on the door, making the appearance of the door more concise and unified. When the sliding cover is closed, the entire device looks no different from a traditional door handle. This design not only allows the handle to blend in with the door in appearance, but also hides the keyhole without attracting attention, thereby increasing the overall safety of the door. By hiding the keyhole, it reduces the risk of the door lock being violently damaged.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 5 A sliding lock protector is shown, comprising a base 1, on which a keyhole 11 for installing a lock core is provided, and a key can be inserted into the lock core through the keyhole 11 to unlock the lock. A sliding cover 2 is slidably connected to the outer side of the base 1, and can slide up and down to cover or expose the keyhole 11. The sliding cover 2 plays a role in protecting the keyhole of the lock core at the keyhole 11, that is, the sliding cover 2 can slide up and down along the base 1 to cover or expose the keyhole 11. Such a design is not only easy to operate and avoids cumbersome opening steps, but also greatly protects the keyhole from dust and other possible external damage.

[0032] The base 1 is provided with an inner plug hole 12, and an inner pin 4 is movably connected inside the inner plug hole 12. The inner pin 4 is designed to slide inward and outward in the inner plug hole 12, and can extend out of the base 1 when necessary. This mobility allows the inner pin 4 to interact with relevant parts of the slide cover 2 to achieve a mechanism for locking or unlocking the slide cover 2.

[0033] A first elastic reset member 5 is also installed inside the inner plug hole 12. This elastic reset member 5 is usually a spring, which continuously applies force to the inner pin 4, causing it to tend to the outward position. When the inner plug hole 12 is aligned with the outer plug hole 21, the inner pin 4 can be inserted into the outer plug hole 21 under the action of the first elastic reset member 5, thereby locking the slide cover 2. This simple and effective mechanism achieves the locking of the slide cover 2 through physical interlocking. After the slide cover 2 is locked, it cannot slide at will, thereby protecting the keyhole 11 from dust, moisture or other potentially damaging substances. The user does not need to take any additional actions at ordinary times, and the lock protector automatically provides continuous protection for the keyhole.

[0034] The design of the slide cover 2 corresponds to that of the base 1, and is provided with an outer plug hole 21, corresponding to the inner pin 4. In the outer plug hole 21, an outer pin 6 is also movably connected, and the outer pin 6 can slide inward and outward in the outer plug hole 21, and can extend outward and inward from the slide cover 2. Such a design allows the user to manually control the unlocking state of the slide cover 2 by pressing the outer pin 6 inward to push the inner pin 4 out of the outer plug hole 21, thereby allowing the slide cover 2 to slide freely and expose the keyhole 11, which is convenient for the user to operate the key.

[0035] In order to keep the outer pin 6 in the preset position when there is no external pressure, a second elastic reset member 7 is also installed inside the outer plug hole 21. This device is usually also a spring, and its function is to continuously push the outer pin 6 outward so that it can automatically return to the outward extended state when there is no external force. Only when the user actively presses the outer pin 6 to overcome the elastic force of the first elastic reset member 5 and the second elastic reset member 7, the outer pin 6 will move to the unlocked position, thereby allowing the sliding cover 2 to slide freely.

[0036] During the sliding up and down process of the slide cover 2, when the slide cover 2 slides into place so that the inner insertion hole 12 is aligned with the outer insertion hole 21, the outer end of the inner pin 4 is automatically pressed outward and inserted into the outer insertion hole 21 due to the action of the first elastic reset member 5. This action firmly limits the further sliding of the slide cover 2, thereby keeping the slide cover 2 in the locked position.

[0037] When the user needs to unlock, the position lock can be released by a simple pressing operation. That is, when unlocking from the keyhole, the user only needs to manually press the outer end of the outer pin 6 inward, so that the inner end of the outer pin 6 presses the inner pin 4 inward, forcing the inner pin 4 to overcome the resistance of the first elastic reset member 5, withdraw from the outer plug hole 21, and retract into the inner plug hole 12. In this way, the unlocking mechanism is completed, the slide cover 2 is released, and the user can smoothly slide the slide cover 2 to expose the keyhole hole 11.

[0038] After inserting the key to unlock or lock the door, the user can also easily slide the sliding cover 2 to cover the keyhole hole 11 again, thereby restoring the protection of the keyhole.

[0039] The utility model adopts a clutch-type locking structure, and the clutch of the inner pin 4 and the outer plug hole 21 can realize the locking and unlocking of the sliding cover 2. Among them, the inner pin 4 can be automatically connected with the outer plug hole 21 under the action of the elastic reset member, and the separation of the inner pin 4 and the outer plug hole 21 only requires manually pressing the outer pin 6 inward.

[0040] Overall, the design of this sliding lock guard is extremely user-friendly. It not only has a simple structure, but also simplifies the operation procedure. The lock can be unlocked by simply pressing and sliding, reducing the inconvenience in use. At the same time, the structure also takes into account the appearance. The sliding cover can hide the keyhole, reducing the abruptness. In addition, due to the simplicity of the structure, its manufacturing cost is relatively low.

[0041] Specifically, in terms of operation, the user only needs to press lightly to unlock, and then slide the slide cover to use the key. This integrated action greatly reduces the user's manual labor when opening or closing the lock, especially when in a hurry or carrying items, this design is particularly considerate. After unlocking, the smooth sliding of the slide cover allows quick and direct operation of the keyhole without other complicated gestures or tools.

[0042] In terms of appearance design, the perfect combination of the sliding cover and the lock body not only improves the overall aesthetics, but also hides the keyhole through its streamlined appearance design, making it integrated with the door surface, reducing the direct impact of the external environment on the keyhole, while avoiding the safety hazards caused by the exposed keyhole. In addition, the hidden design also provides the lock with a more concise and modern appearance, getting rid of the impression that traditional locks often give people that they are heavy and bulky.

[0043] In terms of cost, the simple structural design means lower material consumption and processing time, which is a significant advantage for manufacturers. Reducing the use of complex components also reduces potential failure points, thereby improving product reliability and durability.

[0044] More specifically, the sliding cover 2 is connected with a handle 3. The handle 3 not only improves the convenience of the user when operating the sliding cover, but also serves as a door handle, thereby achieving multifunctionality. The existence of the handle 3 eliminates the need to install an additional separate door handle. This dual-purpose design concept reduces the number of accessories on the door, making the appearance of the door more concise and unified.

[0045] The shape and size of the handle 3 are designed to be like a common door handle, so that when the sliding cover 2 is closed, the entire device looks no different from a traditional door handle. This design not only allows the handle 3 to blend in with the door in appearance, but also hides the keyhole without attracting attention, thereby increasing the overall safety of the door. Because the keyhole is not easy to be found, the possibility of the lock being damaged or unlocked by technology is reduced, thereby improving the protection capability of the door.

[0046] In terms of safety and aesthetics, the slide cover 2 with the handle 3 plays a dual role. First, by hiding the keyhole, it reduces the risk of the door lock being violently damaged. Second, from an aesthetic point of view, the combination of the handle 3 and the slide cover 2 presents a modern, simple design style that can be matched with a variety of different door designs and interior decoration styles, providing users with more choices.

[0047] In terms of practicality, the integrated handle 3 also provides a better mechanical grip point, making it easier for the user to slide the sliding cover 2, especially when there are other objects on the hand or the hand is wet. This is particularly important. In addition, this design also saves production costs, because the integration of the door handle function reduces the need to manufacture and install additional accessories, which means that there is also added value in economic benefits.

[0048] Therefore, the sliding lock protector with the handle 3 achieves an excellent balance in terms of practicality, safety, aesthetics and economy.

[0049] More specifically, a damping structure is provided between the base 1 and the sliding cover 2. The damping structure provides a smooth and powerful damping feeling for the movement of the sliding cover 2, ensuring stability and accuracy during the sliding process.

[0050] Furthermore, the damping structure includes a plurality of receiving holes 13 provided at the lower portion of the outer side surface of the base 1, marbles 131 provided in the receiving holes 13 and capable of extending outward to press against the inner side surface of the sliding cover 2, and a third resetting elastic member 132 (preferably a spring) provided between the marbles 131 and the receiving holes 13 and pressing the marbles 131 outward. This structure effectively transmits the resetting force to the sliding cover 2, ensuring the smoothness and consistency of the sliding operation.

[0051] Furthermore, the upper and lower parts of the inner side surface of the sliding cover 2 are respectively provided with a lower limit positioning groove 22 and an upper limit positioning groove 23 for the corresponding marbles 131 to be inserted into, and when the sliding cover 2 slides to the lower limit, each marble 131 is inserted into the corresponding lower limit positioning groove 22; when the sliding cover 2 slides to the upper limit, each marble 131 is inserted into the corresponding upper limit positioning groove 23.

[0052] The lower limit positioning groove 22 and the upper limit positioning groove 23 are preferably spherical grooves.

[0053] The interaction between the marble 131 and the third resetting elastic member 132, as well as the cooperation with the lower limit positioning groove 22 and the upper limit positioning groove 23 on the inner side of the sliding cover 2, together create a mechanical linkage mechanism that helps to position the sliding cover 2. When the sliding cover 2 moves to any end of its motion range, the corresponding marble 131 will be stuck in the corresponding arc groove, and this design provides clear positioning.

[0054] The damping structure (the marble 131, the third reset elastic member 132, the lower limit positioning groove 22 and the upper limit positioning groove 23) can not only provide damping when the sliding cover 2 slides up and down, preventing the sliding cover 2 from sliding randomly, and preventing the sliding cover 2 from producing unexpected movement due to external force or vibration during use, thereby increasing safety during use, but also provides a good operating feel, making the sliding control more precise, smooth and stable.

[0055] In addition, the cooperation between the marble 131 and the lower limit positioning groove 22 and the upper limit positioning groove 23 can not only play a positioning role, but also provide a "click" sound feedback to indicate to the user that the sliding cover 2 has slid to the upper limit or lower limit position to ensure that it does not slide excessively. This sound feedback mechanism is a combination of touch and hearing in human-computer interaction, providing a non-visual confirmation method, which can effectively guide user operations, especially when the line of sight is inconvenient.

[0056] More specifically, the sliding connection structure between the slide cover 2 and the base 1 is specifically exemplified as follows: the left and right sides of the slide cover 2 are provided with slide grooves 24 in the up-down direction, and the left and right sides of the base 1 are provided with slide platforms 14 that slide and cooperate with the corresponding slide grooves 24. The arrangement of the slide grooves 24 and the slide platform 14 allows the slide cover 2 to slide smoothly along the base 1 in the up-down direction, and this process is precisely guided and limited in a given trajectory, ensuring the stability of the structure and the consistency of movement.

[0057] More specifically, a guide mechanism is provided between the slide cover 2 and the base 1, and the introduction of the guide mechanism further increases the accuracy of the sliding control. The specific structure is as follows: the outer side surface of the base 1 is provided with a guide groove 15 in the up-down direction, and the inner side surface of the slide cover 2 is provided with a guide slider 25 that slides with the guide groove 15. This structure not only plays a role in accurately guiding the movement of the slide cover 2, but also prevents the slide cover 2 from swinging or deflecting during the movement, greatly improving the smoothness and reliability of the sliding mechanism.

[0058] In addition, the existence of the limiting structure is crucial for safety. A limiting structure is also provided between the slide cover 2 and the base 1, and the specific structure is as follows: a limiting surface 151 is provided at the upper end of the guide groove 15 for limiting the upward escape of the guide slider 25. The purpose of this design is to prevent the guide slider 25 from excessively moving upward and eventually escape, and it is the upper limit of the guide slider 25, ensuring that the slide cover 2 will not accidentally fall off during use.

[0059] Furthermore, the inner plug hole 12 is arranged in the guide groove 15, and when the inner plug hole 12 is not aligned with the outer plug hole 21, the outer end of the inner pin 4 extends outward and abuts against the inner side surface of the slide cover 2. That is, the outer end of the inner pin 4 is not completely retracted into the inner plug hole 12, but extends a portion (the extension length is equal to the depth of the guide groove 15), and the extended portion can be blocked below the guide slider 25, serving as the lower limit of the guide slider 25, thereby limiting the guide slider 25 from excessively sliding downward or falling out.

[0060] The above anti-escape safeguards are implemented through simple mechanical interactions, which not only improves the reliability of the entire system but also reduces the manufacturing and maintenance costs.

[0061] More specifically, a pressure cover 8 is detachably connected to the inner opening of the outer plug hole 21, and the pressure cover 8 is preferably connected to the sliding cover 2 by screws, and the second elastic reset member 7 is arranged between the pressure cover 8 and the outer pin 6. Such a structure can facilitate the disassembly and assembly of the second elastic reset member 7 and the outer pin 6.
