Description

Technical Field

[0001] This utility model relates to the field of disinfection devices, specifically a disinfection device for dental instruments. Background Technology

[0002] Dental instrument sterilization is a crucial step in dental treatment. Its purpose is to effectively kill or remove pathogenic microorganisms from instruments, prevent cross-infection, and ensure the health and safety of patients and healthcare workers. Appropriate sterilization methods are selected based on the instrument's intended use and level of risk. Among these methods, pressure steam sterilization is one of the most commonly used and effective, suitable for instruments and items resistant to high temperatures and humidity. High-temperature, high-pressure steam penetrates the interior of the instrument, killing all microorganisms, including bacterial spores.

[0003] Existing pressure steam sterilizers are generally equipped with multi-layer shelves, which can sterilize multiple instruments at once. The distance between each shelf is the same. After closing the cabinet door, the internal sterilization device is turned on. However, dental instruments come in various sizes. When the distance between two shelves is too small, one shelf needs to be removed. This wastes the internal space of the pressure steam sterilizer and also affects the number of instruments that can be sterilized at one time, resulting in a decrease in the efficiency of the pressure steam sterilizer. Utility Model Content

[0004] The purpose of this utility model is to provide an oral instrument disinfection device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dental instrument disinfection device, comprising a pressure steam sterilizer, wherein four support rails are fixedly installed on the inner wall of the pressure steam sterilizer, the four support rails are symmetrically distributed in pairs, and multiple shelves are arranged between the four support rails, the shelves are slidably connected to the support rails via sliding blocks, and multiple equally spaced slots are provided on the outer ends of the support rails;

[0006] An adjustment component is provided between the support rail and the shelf to lock or unlock the sliding connection between the support rail and the shelf, so as to adjust the spacing between the multiple shelves.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7 In this embodiment of the present invention, an oral instrument disinfection device includes a pressure steam sterilizer 1. Four support rails 2 are fixedly installed on the inner wall of the pressure steam sterilizer 1. The four support rails 2 are symmetrically distributed in pairs. Multiple shelves 3 are arranged between the four support rails 2. The shelves 3 are slidably connected to the support rails 2 through slides 31. Multiple slots 21 are evenly distributed on the outer end of the support rails 2.

[0026] An adjustment component 4 is provided between the support rail 2 and the shelf 3 to lock or unlock the sliding connection between the support rail 2 and the shelf 3, so as to adjust the spacing between multiple shelves 3.

[0027] The adjustment component 4 includes four slide rails 401, which are symmetrically distributed at both ends of the shelf 3 in pairs. Each of the four slide rails 401 has a sliding connecting strip 402 on its inner side, and a movable block 403 is provided between two adjacent connecting strips 402.

[0028] One end of the connector 402 can be inserted into the slot 21, and the other end of the connector 402 is slidably connected to the movable block 403; both ends of the movable block 403 are provided with sliders 4010, and the connector 402 has a groove 409 at one end that matches the slider 4010.

[0029] The adjustment assembly 4 also includes multiple bearing seats 404, which are equidistantly distributed on the same horizontal line in the middle of the shelf 3. All bearing seats 404 are fixedly connected to the middle of the shelf 3. A shaft 405 is rotatably connected between the multiple bearing seats 404. The two ends of the shaft 405 are respectively connected to two movable blocks 403 by threads.

[0030] Both ends of the shaft 405 are threaded, and the threads on the outer walls of the two ends of the shaft 405 turn in opposite directions. A screw head 406 is connected to one end of the shaft 405 near the opening of the pressure steam sterilizer 1.

[0031] The bottom surface of the shelf 3 is provided with a guide groove 407 at the position of the movable block 403, and the bottom of the movable block 403 is provided with a guide block 408 that matches the guide groove 407.

[0032] The end of the connector 402 near the movable block 403 is an inclined surface, and both ends of the movable block 403 are inclined surfaces. The inclination angles of the contact surfaces of the connector 402 and the movable block 403 are matched.

[0033] In this embodiment: by setting an adjustment component 4 between the support rail 2 and the shelf 3, the locking state between the support rail 2 and the shelf 3 can be controlled by the adjustment component 4, thereby facilitating the adjustment of the relative position height of the shelf 3, so that the spacing between multiple shelves 3 can be reasonably controlled according to the size of the oral instruments, and maximizing the utilization rate of the internal space of the pressure steam sterilizer 1.

[0034] Specifically, when it is necessary to adjust the height of the shelf 3, the knob 406 is turned to force the shaft 405 to rotate. The rotating shaft 405 drives the movable block 403 to move along the length of the guide groove 407 under the action of the threads at both ends. Since the two sets of insert strip 402 and movable block 403 are slidably connected by slide groove 409 and slider 4010, when the movable block 403 moves, the insert strip 402 will also move along the length of the slide rail 401, thereby causing one end of the insert strip 402 inserted into the slot 21 to be pulled out of the slot 21. At this time, the support rail 2 and the shelf 3 are unlocked, and the staff can manually adjust the shelf 3 to slide along the length of the support rail 2.

[0035] Once the shelf 3 reaches the designated height, the screw head 406 is turned in the opposite direction, which, driven by the shaft 405, moves the movable block 403 back to its original position. The movable block 403 also moves the connector 402 along the length of the slide rail 401 to reset, allowing one end of the connector 402 to be inserted into the slot 21, thus completing the sliding lock between the support rail 2 and the shelf 3. This adjustment structure is easy to operate, requiring only the screw head 406 to be turned in both directions, greatly improving adjustment efficiency and making it suitable for widespread application.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
