[0002] Interior door handle locks are common hardware accessories widely used in interior doors of residential, office, hotel, hospital and commercial spaces. They are commonly found in bedrooms, bathrooms, office partitions and other places where privacy and convenience need to be considered. Their main function is to open, close and lock the door to ensure safety and privacy. At the same time, they serve as a human-computer interaction interface. As an important part of the door decoration, their shape, material and surface treatment process directly affect the overall decoration style and aesthetics. A typical structure consists of an outer handle, an inner handle, a drive shaft, a lock body and connecting fasteners. The handles on both sides are fixed by long bolts or connecting rods through the door panel and nuts or buckles, realizing transmission linkage and synchronous operation.

[0003] Currently, most interior door handle locks use a bolt-through structure. Installation requires passing a long bolt through the door panel, lock body, and handle, and then securing it with a nut on the inside. This relies on tools such as screwdrivers, making the process cumbersome and time-consuming, especially inconvenient for batch installations or when space is limited. Subsequent disassembly, cleaning, replacement, or repair requires repeated disassembly and reassembly, easily causing problems such as stripped threads and scratches on the door panel. While some quick-install structures simplify the process, they suffer from defects such as weak connections, easy loosening and rattling, and poor durability, making it difficult to meet the stability requirements of high-frequency use and high-quality environments.

[0004] Therefore, it is necessary to design an interior door handle lock that is easy to install and remove in order to solve the above-mentioned technical problems. Utility Model Content

[0023] Example: An easy-to-install and remove interior door handle lock, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a door panel 1, a locking post 2, a first mounting block 3, a first door handle 4, a spring 6, a limiting cylinder 7, a locking block 9, a second mounting block 10, and a second door handle 11. The door panel 1 has a through hole through which the locking post 2 passes and is installed on the door panel 1 by screws. The front end of the locking post 2 extends out of the door panel 1 and is installed on the first mounting block 3 by screws. The first door handle 4 is installed on the first mounting block 3. The rear end of the locking post 2 is fitted with a slidable limiting cylinder 7. The end of the limiting cylinder 7 away from the door panel 1 is installed on the second mounting block 10 by screws. The second door handle 11 is installed on the second mounting block 10 by screws. The outer surface of the locking post 2 has multiple locking grooves 5 evenly distributed. The locking block 9 is installed in the locking groove 5. The bottom of the locking block 9 is connected to the inner wall of the locking groove 5 by the spring 6. The outer surface of the limiting cylinder 7 has multiple limiting grooves 8 corresponding to the position of the locking block 9. The side surface of the locking block 9 facing the limiting cylinder 7 is designed as an inclined surface.

[0024] like Figure 2 , Figure 3 and Figure 5 As shown, it also includes a first unlocking ring 12, a sliding rod 13, a second unlocking ring 14, and a nut 15. The first unlocking ring 12 is sleeved on the outer wall of the rear part of the limiting cylinder 7. Multiple sliding rods 13 are evenly connected to the rear end of the first unlocking ring 12 by welding. The multiple sliding rods 13 extend rearward and pass through the second mounting block 10. The second unlocking ring 14 is slidably connected to the second door handle 11. The ends of the multiple sliding rods 13 are connected to the second unlocking ring 14. The outer surface of the second door handle 11 is threaded and threadedly connected to the nut 15.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes an infrared sensor 16, an LED light 17 and a control switch button 18. An infrared sensor 16 is installed on the upper part of the first door handle 4, an LED light 17 is provided in the lower middle part of the first door handle 4, and a control switch button 18 is installed on the left side of the first door handle 4.

[0026] When installing a door handle, first, pass the locking pin 2 through the through hole in the door panel 1 and securely fix it to the door using its built-in fixing structure, ensuring the stability of the entire assembly's axis. The front end of the locking pin 2 extends out of the door to connect to the outer components; space is left at the rear end for the installation of the inner structure. Next, fit the first mounting block 3 onto the front end of the locking pin 2 and lock it in place. Then, install the first door handle 4 onto the first mounting block 3. At this point, the outer handle part is assembled and serves as the main grip point for daily door opening and closing. Subsequently, the installation of the inner handle begins. Partial: Align the limiting cylinder 7 with the rear end of the locking pin 2 and slowly push it in. During the pushing process, the front end of the limiting cylinder 7 contacts the inclined surface of the locking block 9. Since the bottom of the locking block 9 is connected to the spring 6, it will retract downward into the locking groove 5 after being pressed, achieving smooth sliding in. When the limiting cylinder 7 is fully pushed in, the elastic force of the spring 6 causes the locking block 9 to automatically bounce upward and lock into the limiting groove 8 on the outer wall of the limiting cylinder 7, making a clear "click" sound, indicating that the mechanical locking is completed. At this time, the limiting cylinder 7 cannot move, ensuring that the second door handle 11 is stable and does not fall off.

[0027] Next, the first unlocking ring 12 is fitted onto the outer wall of the limiting cylinder 7, and its rear end is connected to multiple evenly distributed sliding rods 13. The sliding rods 13 pass backward through the second mounting block 10, and their ends are connected to the second unlocking ring 14. The second unlocking ring 14 is fitted onto the second door handle 11 and can slide freely, forming a linkage structure that can be operated from both sides. This design allows the user to perform the disassembly operation by pushing the first unlocking ring 12 or the second unlocking ring 14, whether from inside or outside the door. Then, pick up the limiting cylinder 7, which has been pre-assembled with the second door handle 11 and the second mounting block 10, and slowly push it into place, aligning it with the rear end of the locking post 2, to complete the assembly of the inner handle. Finally, tighten the nut 15 onto the thread on the outer surface of the second door handle 11 to press the second mounting block 10, which serves to prevent loosening and prevent the structure from loosening under long-term door opening and closing vibrations. At this point, the entire door handle is installed, and the user can rotate the first door handle 4 or the second door handle 11 normally to open and close the door lock.

[0028] When a person approaches the door panel 1 at night, the infrared sensor 16 on the upper part of the first door handle 4 detects the approach of a person and automatically triggers the LED light 17 in the middle and lower part to light up, providing convenient lighting. The control switch button 18 can be used to manually switch the lighting mode (such as off, always on, sensor). All electronic functions are powered by the built-in rechargeable battery, eliminating the need for external wiring and ensuring freedom of disassembly and assembly.

[0029] When the door handle needs to be removed (e.g., for cleaning, replacement, or moving), simply unscrew the nut 15 counterclockwise to release the lock. Then, push the first unlocking ring 12 or the second unlocking ring 14 with your fingers. The sliding rod 13 will move in tandem, and its end will press down on the inclined surface of the locking block 9, forcing the locking block 9 to overcome the spring force of the spring 6 and retract into the locking groove 5, disengaging from the limiting groove 8. The mechanical lock will then be released. At this point, hold the second door handle 11, and it, along with the second mounting block 10, the limiting cylinder 7, the first unlocking ring 12, the second unlocking ring 14, the sliding rod 13, and other components, can be smoothly slid out along the locking post 2, achieving quick and non-destructive disassembly. The first door handle 4 and the first mounting block 3 can be left on the door panel 1 for aesthetic purposes. If complete removal is required, simply use a simple tool to remove the locking post 2.
