Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to an antibacterial coating door lock. Background Art

[0002] Any surface in our lives can become a breeding ground for microorganisms. The usage environment, frequent contact, and improper cleaning can lead to the uncontrolled growth of bacteria, mold, and viruses, which can have a significant impact on our lives. For example, at home, we often need to go to the bathroom to clean our hands, and opening and closing the bathroom door requires touching the handle. Especially after washing hands, we may still touch the handle and pick up bacteria from previous use. In public places such as hospitals, nursing homes, and schools, we are even more likely to be exposed to bacteria through door locks.

[0003] Patent document CN218862304U discloses an internal and external anti-lock lock structure that addresses the anti-lock structural design issues of eco-friendly locks and bathroom locks. It comprises an outdoor handle and an indoor handle. The outdoor handle includes an outer housing, a lock core assembly that docks with a mechanical keyhole, a mounting base, an anti-locking element, and an anti-locking latch. The lock core assembly is fixedly connected to the outer housing via the mounting base. The lock core assembly includes a synchronously rotating tail lock ruler that is axially inserted into the anti-locking element for linkage assembly. The anti-locking element and the anti-locking latch are coaxially assembled, and a locking member is provided between the anti-locking element and the anti-locking latch to limit relative rotation. The lock core lock ruler directly inserts into and drives the anti-locking block inside the handle, ensuring secure anti-locking contact with the steel column. This also increases the height of the steel column and the anti-locking contact surface, thereby improving the lock's compressive strength and preventing false opening. An anti-slip rubber pad is added to the bottom, making the outdoor and indoor screws close together for secure and convenient installation.

[0004] In the above scheme, the lock is relatively complex. Conventional locks require simplicity and convenience, and can be unlocked from both inside and outside, and can be locked from inside the door. However, it is necessary to ensure that the handle has a good rebound effect and the latch is not easy to retract when closing the door. At the same time, the lock does not coat the exposed parts of the lock body and handle to achieve an antibacterial effect. Therefore, it is necessary to provide an antibacterial coated door lock to solve the shortcomings of the existing technology. Utility Model Content

[0039] Example 3:

[0040] In this embodiment, if Figure 1-3 As shown, the inner handle, inner handle cover, outer handle, outer handle cover, small handle and small handle cover are all exposed parts, and their surfaces are sprayed with antibacterial coating, which helps to inhibit the growth of various bacteria, mold, fungi and viruses.

[0041] In this embodiment, the antibacterial coating is an acidic silicone sol containing nanosilver particles. The antibacterial coating is transparent and does not affect the appearance and texture of the substrate. The antibacterial coating has high hardness and strong bonding with the substrate. The thickness of the antibacterial coating is 50nm to 2000nm.

[0042] The working principle of the antibacterial coated door lock body is that the small handle rotates to drive the inner security dial to rotate clockwise until the inner security fork abuts and stops, the inner security pull rod moves downward, the inner security pull seat moves outward, the protrusion and the slot are disengaged, and the lock body is unlocked. Similarly, the opposite is locked; the inner handle or the outer handle can be pressed down to drive the handle dial to rotate clockwise through the square rod, the handle dial abuts the oblique tongue guide plate, driving the oblique tongue pull rod and the oblique tongue to retract, and the handle dial simultaneously drives the I-shaped connecting rod to move inward, the safety seat rotates clockwise, and the safety torsion spring is limited and bent by the limit pin. When the inner handle or the outer handle is released, the safety torsion spring is reset, thereby driving the handle dial to rotate, and the inner handle or the outer handle is reset.

[0043] The working principle of this antibacterial coating is that when positively charged silver ions come into contact with negatively charged microbial cells, they will adsorb each other. The silver ions pierce the cell surface, destroy the cell DNA and inhibit protein formation, making the cells unable to metabolize and reproduce until they die, thereby achieving a sterilization effect. When the cells lose their inactivity, the silver ions leave and continue to fight bacteria, with a sustained antibacterial effect without toxicity or side effects.
