[0002] Door locks are a common structure, mainly composed of a handle and a lock. The handle and lock must be connected as a whole, and the handle and lock must be able to rotate relative to each other. Traditional security doors or ordinary doors have external handles, which require the user to move the handle to use them.
[0003] However, when the weather is relatively dry, static electricity often occurs due to the material of the handle, which can be bothersome for users. Therefore, there is a need to provide a silent door handle to solve the above problems. Utility Model Content

A bearing seat 4 is installed in the middle of the lock panel 2, and a handle 7 is installed in the middle of the bearing seat 4. A square rod 5 is installed at the end of the handle 7 near the lock panel 2 and passes through the lock panel 2. An extension handle 8 is fixedly connected to the end of the handle 7 away from the square rod 5, and the handle 7 and the extension handle 8 are arranged in an L-shape. A mounting screw 3 is threadedly connected to one end of the lock panel 2, and there are four mounting screws 3, which are symmetrically distributed at both ends of the lock panel 2. A sound insulation plate 6 is connected to the inner wall of the lock panel 2, and the outer wall of the sound insulation plate 6 is tightly fitted to the inner wall of the lock panel 2.
[0023] Please see Figure 1 , Figure 2 , Figure 3As shown, the protective component 9 includes a mounting sleeve 10, with a T-shaped mounting rail 11 inside and a rubber protective sleeve 13 on the outside. A positioning plate 14 is provided at one end of the mounting sleeve 10, and a threaded rod 15 is provided on the side of the positioning plate 14. The mounting sleeve 10 is fitted over the extension handle 8, and the middle of the mounting sleeve 10 is hollow. Two T-shaped mounting rails 11 are fixedly connected to the inner wall of the mounting sleeve 10, symmetrically distributed on the top and bottom inner walls of the mounting sleeve 10. A mounting groove 12 is provided on the outer wall of the extension handle 8. There are two mounting grooves 12, which are symmetrically distributed on the top and bottom outer walls of the extension handle 8. The interior of the mounting groove 12 is slidably connected to a T-shaped mounting rail 11, and the mounting groove 12 and the T-shaped mounting rail 11 are correspondingly set. A rubber protective sleeve 13 is fixedly connected to the outer wall of the mounting sleeve 10. The protective component 9 is set on the outside of the extension handle 8 to protect the extension handle 8 and the user. The mounting sleeve 10 and the rubber protective sleeve 13 separate the extension handle 8 to prevent the user from directly contacting the extension handle 8 and generating static electricity, thereby improving the comfort of using the handle 7 and the extension handle 8.
[0024] A threaded groove 16 is provided in the middle of the end of the extension handle 8 away from the handle 7. A threaded rod 15 is threadedly connected inside the threaded groove 16. A positioning plate 14 is fixedly connected to the end of the threaded rod 15 away from the threaded groove 16. The side of the positioning plate 14 near the threaded rod 15 contacts the outer wall of the extension handle 8 and one end of the T-shaped mounting slide rail 11. An anti-slip groove 17 is provided on the outer wall of the positioning plate 14. A cross-shaped groove 18 is provided in the middle of the side of the positioning plate 14 away from the threaded rod 15. The T-shaped mounting slide rail 11 is slidably connected to the inside of the mounting groove 12, which facilitates the disassembly of the rubber protective sleeve 13 and the mounting sleeve 10, and facilitates the replacement and cleaning of the rubber protective sleeve 13. The positioning plate 14 is connected to one end of the extension handle 8 through the threaded rod 15, thereby limiting the position of the mounting sleeve 10 and the rubber protective sleeve 13 and improving the stability of the device.
[0025] It should be noted that this utility model is a silent door handle. In use, the lock panel 2 is installed in the desired position using mounting screws 3. A sound insulation plate 6 is installed inside the lock panel 2, thereby achieving sound insulation between the two lock panels 2 and reducing noise transmission caused by unlocking and closing. An extension handle 8 is fixedly connected to the end of the handle 7 away from the lock panel 2. An installation sleeve 10 and a rubber protective sleeve 13 are installed on the outer wall of the extension handle 8. A T-shaped mounting rail 11 is fixedly connected to the inner wall of the installation sleeve 10. During installation, the T-shaped mounting rail 11 on the inner wall of the installation sleeve 10 is aligned with the mounting groove 12 on the outer wall of the extension handle 8. The installation sleeve 10 is then pushed, causing the installation sleeve 10 and the T-shaped mounting rail 11 to slide respectively outside the extension handle 8 and inside the mounting groove 12, thus allowing the installation sleeve... 10 drives the rubber protective sleeve 13 to be fitted onto the outside of the extension handle 8. Then, the threaded rod 15 on one side of the positioning plate 14 is aligned with the threaded groove 16 at one end of the extension handle 8. The positioning plate 14 is rotated so that the threaded rod 15 is threaded into the inside of the threaded groove 16. The side of the positioning plate 14 near the threaded rod 15 contacts the side of the T-shaped mounting slide rail 11 and the mounting sleeve 10, thereby achieving a limiting connection between the mounting sleeve 10 and the rubber protective sleeve 13. This prevents the mounting sleeve 10 and the rubber protective sleeve 13 from falling off the outside of the extension handle 8 during use, which would affect the stability of the device. In addition, the outer wall of the positioning plate 14 is provided with an anti-slip groove 17, and the side of the positioning plate 14 away from the threaded rod 15 is provided with a cross-shaped groove 18, which facilitates the disassembly of the positioning plate 14 in various ways and improves the practicality of the device.
