Description

Technical Field

[0001] The present invention relates to a door handle, and particularly to a concealed door lock handle structure. Background Art

[0002] With the improvement of people's living standards, the requirements for the safety, comfort and aesthetics of the living environment are increasing day by day. As the first line of defense for home security, the performance and user experience of the entrance door have attracted much attention. Currently, most entrance doors on the market adopt surface-mounted door handles, and such door handles protrude about 6 centimeters from the door surface. In the actual use process, there are many drawbacks to such door handles: on the one hand, when opening the door, due to the protrusion of the door handle, it is very easy to hit the wall, which may not only damage the wall, but also affect the service life of the door handle after long-term collisions; on the other hand, when people walk indoors, the protruding door handle is also likely to collide with the human body, bringing inconvenience and even causing harm to people. In addition, from the aesthetic point of view, the surface-mounted door handle destroys 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 problem in this field. Summary of the Invention

[0003] The present invention aims to provide a concealed mechanical door handle to solve the problems that the existing surface-mounted entrance door handles are prone to hitting the wall and colliding with people during use, and at the same time improve the aesthetics and rationality of space utilization of the entrance door, bringing a safer, more comfortable and more beautiful user experience to users.

[0004] The above object of the present invention is achieved by the following technical solutions: a concealed door lock handle structure, including a door lock panel, the door lock panel is provided with a groove and pivotally connected with a door handle. Under normal conditions, the surface of the door handle is flush with the door lock panel, that is, in the same plane. A slide rail is provided inside the door lock panel, and a slider assembly is installed. A rack is provided on the slider assembly; a square rotating shaft is provided on the door lock panel, and a gear meshing with the rack is fixed on the square rotating shaft. When the slider assembly slides, it drives the rack to drive the gear to rotate, thereby driving the square rotating shaft to rotate; one side of the pivot connection of the door handle is provided with a pressing part, and the other side is a hand-pulling part. One side of the pressing part extends inward with a driving end, and the driving end is located on one side of the slider assembly and there is a gap between the driving end and the slider assembly.

[0005] Further, in order to enable the door handle to automatically reset after use, a reset spring is provided on one side of the slider assembly. When the door handle is used up, the reset spring will push the slider to move, thereby driving the door handle to return to the initial position.

[0006] Further, the slider assembly includes a slider body, a detachable frame, a rack, and a return spring. A rectangular opening is provided in the middle of the slider body, and the detachable frame is installed in the rectangular opening. The rack is provided on one side of the detachable frame and is integrally formed with the detachable frame; the gear meshing with the rack is located inside the detachable frame. This design enables the replacement of the rack or gear without replacing the entire slider when necessary, reducing the maintenance cost and difficulty.

[0007] Further, considering the diversification and intelligent trend of the door lock function, a display screen is provided on the door lock panel. The display screen can be used to display the working status, power information, operation prompts, etc. of the door lock, facilitating users to use and manage the door lock.

[0008] Further, a lock core decorative cover plate is provided at the lock core hole of the door lock panel. On the one hand, it can protect the lock core and prevent dust and debris from entering; on the other hand, it can also enhance the overall aesthetic appearance of the door lock.

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

[0010] Further, an iron sheet is inlaid 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 the present invention: When the user needs to open the door, gently press the edge of one side of the pressing part of the handle with the hand, and the handle will rotate about 15° around the pivoting point. At this time, the driving end moves within the clearance space between it and the slider assembly. During this process, the square rotating shaft does not rotate, and the side of the pulling part of the handle will lift up, and at this time the user can insert a finger. Then, pull the handle forcefully, and the handle continues to rotate, and its driving end will push the rack on the slider to move. The movement of the rack drives the gear on the square rotating shaft to rotate, so that the square rotating shaft and the gear rotate synchronously by about 45 degrees. When the square rotating shaft is inserted into the corresponding square hole on the lock body, the lock body can be opened by rotating the square rotating shaft.

[0012] After the door opening action is completed, release the handle with the finger, and the return spring on one side of the slider will generate a thrust force to push the slider to move back. The movement of the slider drives the rack to move in the reverse direction, and then drives the square rotating shaft gear and the handle to rotate back, and the square rotating shaft and the gear rotate synchronously. When the handle rotates to about 15°, the rack returns to the initial position and stops moving. At this time, the square rotating shaft has been reset. Since an iron sheet is inlaid on the handle and a magnet is provided on the door lock panel at the corresponding position, when the handle rotates to about 15°, the iron sheet enters the magnetic field range of the magnet, and under the suction force of the magnet, the handle will continue to rotate until it returns to the initial position of 0°, and at this time the surface of the handle is again flush with the door lock panel.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Significantly improved safety: The hidden door lock handle structure installs the handle embedded in the door leaf, making the surface of the handle flush with the door surface. In this way, when opening the door, the handle will no longer hit the wall, avoiding damage to the wall and damage to the handle due to collision. At the same time, it also eliminates the safety hazard of people hitting the handle when walking indoors, effectively ensuring people's personal safety.

[0014] 2. Greatly enhanced aesthetics: After adopting the hidden design, the appearance of the entrance door is more concise and smooth, without the protruding handle damaging the overall aesthetics. This design can better integrate with various modern home decoration styles, improving the aesthetics of the entrance door and thus enhancing the decoration grade of the entire house.

[0015] 3. More reasonable space utilization: Compared with the traditional surface-mounted handle that occupies additional space, this hidden mechanical handle does not protrude, saving space to a certain extent. For the relatively compact entrance area, this design can make the indoor space layout more reasonable and improve the space utilization rate.

[0016] 4. Precise and reliable reset: An iron sheet is inlaid on the back of the handle, and a magnet is set at the corresponding position on the door lock panel. Used in conjunction with the reset spring, the handle is more precise and reliable during the reset process. The suction force of the magnet can ensure that the handle accurately returns to the initial position, avoiding the situation where the handle protrudes partially due to incomplete reset, further ensuring the aesthetics and safety of the hidden handle.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] As Figures 1 to 8 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. Among them: Door lock panel 1: It is made of high-strength aluminum alloy material (other materials can also be used in other embodiments), and its surface is treated by a matte process, which not only has good wear and corrosion resistance, but also presents a delicate texture. A groove adapted to the handle 2 is provided on the door lock panel 1. Inside the door lock panel 1, a slide rail 7 made of stainless steel is installed, and its surface is polished to ensure that the slider assembly can slide smoothly on it. A square shaft installation position, a display screen installation area, a lock core hole and a safety knob installation hole are also provided on the door lock panel 1. Among them, the square shaft installation position is used to fix the square shaft 8 to ensure its flexible rotation; a liquid crystal display screen 9 is embedded in the display screen installation area, and the screen is covered with scratch-resistant and wear-resistant tempered glass, which is used to display the working status, power information, operation prompts and other contents of the door lock; a lock core decorative cover plate 10 made of the same aluminum alloy material as the panel is installed at the lock core hole, and it is connected to the panel by hinge, pivot or sliding, which can not only protect the lock core from dust and debris, but also improve the overall aesthetics of the door lock; the safety knob installation hole is used to install a safety knob 11 made of metal material, and the surface of the knob is designed with anti-slip texture to facilitate the user's operation to achieve an additional locking function.

[0027] Handle 2: It is made of aluminum alloy of the same material as the door lock panel 1, and its surface is finely polished, with a smooth and comfortable touch. The handle 2 is pivotally connected to the groove of the door lock panel 1 through a pivot. In the normal state, the surface of the handle 2 is in the same plane as the door lock panel 1. One side of the pivot connection of the handle 2 is a pressing part 201, and the other side is a pulling part 202. The pressing part 201 extends inward with a driving end 203, which is located on one side of the slider assembly and has a suitable gap 12 reserved between it and the slider assembly, which can not only ensure the free rotation of the handle 2, but also accurately push the slider assembly when pressing and pulling. In addition, an iron sheet 13 is accurately inlaid on the back of the handle 2 to provide magnetic cooperation for subsequent reset.

[0028] Slider assembly: It is 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 a metal material adapted to the slide rail 7 to ensure smooth sliding on the slide rail 7. A rectangular opening is provided in the middle of the slider body 3 for installing the detachable frame 4 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, meshing precisely 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 on the slider body 3 of the slider assembly, and the other end is fixed at a specific position on the slide rail 7 or the door lock panel 1. When the handle 2 is used up, the return spring 6 can push the slider assembly to drive the handle 2 to return to its original position.

[0029] Other auxiliary structures: At a position on the door lock panel 1 corresponding to the iron sheet 13 on the back of the handle 2, a high-performance magnet 14 is installed. The magnet 14 has stable magnetism and can generate sufficient suction force with the iron sheet 13 to ensure accurate reset of the handle 2.

[0030] The usage process of the present invention: When the user opens the door, operate according to the above working principle. First, gently press the pressing part 201 of the handle 2 to lift the pulling part 202, put the finger behind the pulling part 202 and pull the handle 2 to achieve the door opening action. After closing the door, release the handle 2, and the handle 2 will automatically return to the initial position under the action of the return spring 6 and the magnet 14.

[0031] In daily use, the user can view the relevant information of the door lock through the liquid crystal display screen 9 on the door lock panel 1. If the insurance function needs to be used, the insurance knob 11 can be rotated to lock. At the same time, regularly check the rotational flexibility of the handle 2, the elasticity of the return spring 6, the adsorption effect between the iron sheet 13 and the magnet 14, and the connection of each component to ensure the normal operation of the door lock handle structure.

[0032] The maintenance process of the present invention: If it is found that the handle 2 rotates smoothly during use, first check whether there is any debris blocking between the slide rail 7 and the slider body 3. If there is debris, clean it and then test. If the problem still exists, check the meshing situation between 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.

[0033] When the return spring 6 shows insufficient elasticity, resulting in the handle 2 not being able to return to its original position normally, the return spring 6 needs to be replaced in time. When replacing, first disassemble the relevant components, take out the old return spring 6, install the new return spring 6, and ensure the correct installation position.

[0034] If the adsorption effect between the iron sheet 13 and the magnet 14 is poor, check whether the iron sheet 13 is loose or whether the magnet 14 has a weakened magnetism. If the iron sheet 13 is loose, fix it again; if the magnet 14 has a weakened magnetism, replace the magnet 14.

[0035] If the liquid crystal display screen 9 fails, such as unclear display or inability to display information, check whether the line connection of the liquid crystal display screen 9 is loose. If the line is normal, it may be necessary to contact a professional for repair or replacement of the liquid crystal display screen 9.
