Description

Technical Field

[0001] This utility model relates to door handles, and more particularly to a concealed door lock handle structure. Background Technology

[0002] As people's living standards improve, their demands for the safety, comfort, and aesthetics of their living environment are increasing. As the first line of defense for home security, the performance and user experience of the entrance door are of paramount importance. Currently, most entrance doors on the market use surface-mounted handles, which protrude about 6 centimeters from the door surface. In actual use, this type of handle has many drawbacks: firstly, when opening the door, the protruding handle is prone to hitting the wall, potentially damaging the wall and shortening its lifespan with repeated impacts; secondly, when people walk inside, the protruding handle is also prone to colliding with people, causing inconvenience and even injury. Furthermore, from an aesthetic point of view, surface-mounted handles disrupt the overall simplicity and smoothness of the entrance door. Therefore, developing a new type of door handle that can solve the above problems has become an urgent issue to be addressed in this field. Utility Model Content

[0003] This utility model aims to provide a concealed mechanical handle to solve the problems of existing surface-mounted door handles being prone to hitting walls and colliding with people during use. At the same time, it improves the aesthetics of the door and the rational use of space, bringing users a safer, more comfortable and beautiful user experience.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: a concealed door lock handle structure, including a door lock panel, the door lock panel having a groove and a handle pivotally connected thereto. Under normal conditions, the surface of the handle is flush with the door lock panel, i.e., on the same plane. The inner side of the door lock panel has a slide rail and a slider assembly is installed thereon, the slider assembly having a rack. The door lock panel has a square rotating shaft, on which a gear meshing with the rack is fixed. When the slider assembly slides, it drives the rack to drive the gear to rotate, thereby driving the square rotating shaft to rotate. The handle has a pressing part on one side of the pivot joint and a pulling part on the other side. A driving end extends inward from one side of the pressing part, the driving end being located on one side of the slider assembly and having a gap between it and the slider assembly.

[0005] Furthermore, to ensure the handle automatically resets after use, a return spring is provided on one side of the slider assembly. When the handle is no longer in use, the return spring pushes the slider to move, thereby causing the handle to return to its initial position.

[0006] Furthermore, the slider assembly includes a slider body, a detachable frame, a rack, and a return spring. The slider body has a rectangular opening in the middle, through which the detachable frame is installed. The rack is positioned on one side of the detachable frame and is integrally formed with it. The gear meshing with the rack is located within the detachable frame. This design eliminates the need to replace the entire slider when the rack or gear needs to be replaced, reducing maintenance costs and complexity.

[0007] Furthermore, considering the diversification and intelligentization trends of door lock functions, a display screen is installed on the door lock panel. The display screen can be used to show the door lock's working status, power information, operation prompts, and other information, making it convenient for users to use and manage the door lock.

[0008] Furthermore, a decorative cover plate for the lock cylinder is installed at the lock cylinder hole on the door lock panel. This can protect the lock cylinder from dust and debris, and also enhance the overall aesthetics of the door lock.

[0009] Furthermore, to enhance door lock security, a safety knob is provided on the lock panel. By turning the safety knob, the door lock can be additionally locked, improving door security and preventing accidental opening.

[0010] Furthermore, an iron sheet is embedded on the back of the handle, and a magnet is provided on the door lock panel at the corresponding position.

[0011] The working principle of this utility model:

[0012] When a user needs to open the door, they gently press the edge of the handle's pressing part. The handle will rotate approximately 15° around the pivot point. At this time, the drive end moves within the gap between itself and the slider assembly. During this process, the square pivot does not rotate, and the handle's pull side will lift up, allowing the user to insert their fingers. Next, pulling the handle forcefully causes it to continue rotating, pushing the rack on the slider. The rack's movement drives the gear on the square pivot to rotate, causing the square pivot and gear to rotate synchronously approximately 45 degrees. When the square pivot is inserted into the corresponding square hole on the lock body, rotating the square pivot will open the lock body.

[0013] After the door is opened, the finger releases the handle. The return spring on one side of the slider generates a pushing force, causing the slider to move back. The slider's movement causes the rack to move in the opposite direction, which in turn drives the square rotating shaft gear and the handle to rotate back, with the square rotating shaft and gear rotating synchronously. When the handle rotates to about 15°, the rack returns to its initial position and stops moving, at which point the square rotating shaft has completed its reset. Because there is an iron plate embedded in the handle, and a magnet is located at a corresponding position on the door lock panel, when the handle rotates to about 15°, the iron plate enters the magnetic field of the magnet. Under the attraction of the magnet, the handle will continue to rotate until it returns to its initial position of 0°, at which point the surface of the handle is once again flush with the door lock panel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Significantly Enhanced Security: This concealed door lock handle structure embeds the handle into the door leaf, making the handle surface flush with the door surface. This prevents the handle from hitting the wall when opening the door, avoiding damage to the wall and the handle itself. It also eliminates the safety hazard of people bumping into the handle while walking indoors, effectively protecting personal safety.

[0016] 2. Significantly Enhanced Aesthetics: The concealed design makes the entrance door look simpler and more streamlined, eliminating the protruding handle that would detract from the overall aesthetics. This design blends better with various modern home décor styles, enhancing the entrance door's appearance and thus elevating the overall sophistication of the house.

[0017] 3. More efficient space utilization: Compared to traditional exposed handles that take up extra space, this concealed mechanical handle does not protrude, saving space to a certain extent. For relatively compact entrance areas, this design can make the interior space layout more rational and improve space utilization.

[0018] 4. Precise and Reliable Reset: An iron plate is embedded on the back of the handle, and a magnet is placed at the corresponding position on the door lock panel. Working in conjunction with the reset spring, this ensures a more precise and reliable reset of the handle. The magnetic force ensures the handle returns accurately to its initial position, preventing the handle from protruding due to incomplete reset, further guaranteeing the aesthetics and security of the concealed handle.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] like Figures 1 to 8 As shown, a concealed door lock handle structure of this embodiment includes a door lock panel 1, a handle 2, a slider assembly, and other auxiliary structures. Wherein:

[0029] Door lock panel 1: Made of high-strength aluminum alloy (other materials may be used in other embodiments), with a frosted surface treatment, possessing both excellent wear and corrosion resistance and a delicate texture. The door lock panel 1 has a groove for fitting the handle 2. Inside the door lock panel 1, a stainless steel slide rail 7 is installed, with a polished surface to ensure smooth sliding of the slider assembly. The door lock panel 1 also includes a square pivot mounting position, a display screen mounting area, a lock cylinder hole, and a safety knob mounting hole. The square pivot mounting position is used to fix the square pivot 8 to ensure its flexible rotation; the display screen mounting area embeds an LCD screen 9, which is covered with scratch-resistant and wear-resistant tempered glass to display the door lock's working status, power information, operation prompts, etc.; the lock cylinder hole is equipped with a lock cylinder decorative cover plate 10 made of aluminum alloy, which is connected to the panel by hinge, pivot or sliding, which can protect the lock cylinder from dust and debris and improve the overall aesthetics of the door lock; the safety knob mounting hole is used to install a metal safety knob 11, the surface of which is designed with anti-slip texture for easy user operation to achieve additional locking function.

[0030] Handle 2: Made of the same aluminum alloy as the door lock panel 1, with a finely polished surface for a smooth and comfortable feel. Handle 2 is pivotally connected to the groove of the door lock panel 1 via a pivot. Under normal conditions, the surface of handle 2 is on the same plane as the door lock panel 1. One side of the pivot joint of handle 2 has a pressing part 201, and the other side has a pulling part 202. The pressing part 201 extends inward to a driving end 203, which is located on one side of the slider assembly and has a suitable gap 12 between it and the slider assembly. This ensures that handle 2 can rotate freely and accurately push the slider assembly when pressed or pulled. In addition, a metal plate 13 is accurately embedded on the back of handle 2 to provide magnetic force for subsequent reset.

[0031] Slider Assembly: Installed on the slide rail 7 inside the door lock panel 1, the slider assembly mainly consists of a slider body 3, a detachable frame 4, a rack 5, and a return spring 6. The slider body 3 is made of metal that matches the slide rail 7, ensuring smooth sliding on the slide rail 7. The slider body 3 has a rectangular opening in the middle for installing the detachable frame 4, which is made of high-strength engineering plastic or metal. The rack 5 is integrally formed with the detachable frame 4. The gear 15 is made of metal and is installed inside the detachable frame 4, precisely meshing with the rack 5. On one side of the slider body 3 of the slider assembly, a return spring 6 made of high-quality spring steel is installed. One end of the return spring 6 is fixed to the slider body 3 of the slider assembly, and the other end is fixed to a specific position on the slide rail 7 or the door lock panel 1. When the handle 2 is not in use, the return spring 6 can push the slider assembly to reset the handle 2.

[0032] Other auxiliary structures: A high-performance magnet 14 is installed on the door lock panel 1 at the position corresponding to the iron plate 13 on the back of the handle 2. The magnet 14 has stable magnetism and can generate sufficient attraction with the iron plate 13 to ensure that the handle 2 is accurately reset.

[0033] The process of using this utility model:

[0034] When opening the door, the user should operate according to the working principle described above. First, gently press the pressing part 201 of the handle 2 to lift the handle part 202. Then, place your finger behind the handle part 202 and pull the handle 2 to open the door. After closing the door, release your finger from the handle 2, and the handle 2 will automatically return to its initial position under the action of the return spring 6 and the magnet 14.

[0035] In daily use, users can view relevant information about the door lock through the LCD screen 9 on the door lock panel 1. If the safety function needs to be used, the safety knob 11 can be turned to lock the door. At the same time, the flexibility of the handle 2, the elasticity of the return spring 6, the attraction effect between the iron plate 13 and the magnet 14, and the connection of each component should be checked regularly to ensure that the door lock handle structure is working properly.

[0036] Maintenance process of this utility model:

[0037] If the handle 2 is found to rotate unevenly during use, first check if there are any obstructions between the slide rail 7 and the slider body 3. If there are any obstructions, clean them before testing. If the problem persists, check the meshing of the rack 5 and the gear 15 to see if there is any wear or misalignment. If necessary, the detachable frame 4 can be disassembled for adjustment or replacement.

[0038] When the return spring 6 becomes insufficiently elastic, causing the handle 2 to fail to return to its normal position, the return spring 6 needs to be replaced promptly. During replacement, first disassemble the relevant components, remove the old return spring 6, install the new return spring 6, and ensure the installation position is correct.

[0039] If the attraction between the iron sheet 13 and the magnet 14 is not good, check if the iron sheet 13 is loose or if the magnet 14 has weakened. If the iron sheet 13 is loose, fix it again; if the magnet 14 has weakened, replace the magnet 14.

[0040] If the LCD screen 9 malfunctions, such as displaying unclear information or failing to display any information, check if the wiring connections of the LCD screen 9 are loose. If the wiring is normal, it may be necessary to contact a professional for repair or replacement of the LCD screen 9.
