Description

Technical Field

[0001] The utility model relates to the technical field of thermometer and hygrometer protection accessories, in particular to a protection frame used for a digital thermometer and hygrometer. Background Art

[0002] The protective frame of a wall-mounted digital thermometer and hygrometer is a device installed on the wall to protect the outer shell and internal components of the digital thermometer and hygrometer from being affected by the external environment. Its main function is to provide mechanical support and protection to prevent the thermometer and hygrometer from being damaged by collision, extrusion or other external forces. It can also reduce the impact of external dust, water vapor, etc. on the thermometer and hygrometer, thereby extending its service life and maintaining accuracy. The structure of this type of protective frame is usually made of solid materials, such as metal or plastic. Its design takes into account the size and shape of the thermometer and hygrometer to ensure good fit and support. For example, an impact-resistant and easy-to-fix thermometer and hygrometer disclosed in authorization announcement number CN219223810U includes a shell and a fixing seat; Shell: A through hole is opened on the rear side, and springs are fixed at the four corners inside the shell. The four springs correspond to each other in a group of two and the front ends are provided with connecting plates. The connecting A mounting bracket is fixed to the front side of the plate, and the fixing seat is arranged inside the shell. A thermometer and hygrometer body is placed inside the fixing seat, which can fix the protective shell by snapping the mounting bracket with the mounting groove.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: a protective frame for a digital thermometer and hygrometer, comprising a circular frame 1 and a rear covering shell 2 fixed on the back of the circular frame 1, a circular inner plate 6 is fixed on the inner wall of the circular frame 1, a digital thermometer body 4 is installed inside the rear covering shell 2, the outer edge of the screen surface of the digital thermometer body 4 is in contact with the inner wall of the circular inner plate 6, a hollow frame 7 is fixed at the corner position inside the circular frame 1, a main protective plate 9 is slidably installed between two hollow frames 7 in the same vertical direction, and a secondary protective plate 10 is slidably installed between two hollow frames 7 in another vertical direction, and the main protective plate 9 and the secondary protective plate 10 are both made of transparent acrylic material;

[0018] The outer walls of both sides of the circular frame 1 are provided with rectangular hollow cavities 5 for the main protective plate 9 and the auxiliary protective plate 10 to slide, and the backs of the main protective plate 9 and the auxiliary protective plate 10 are provided with gear rack transmission structures for sliding toward each other;

[0019] The outer wall of the rear covering shell 2 is fixed with protruding feet 3, and the inside of the protruding feet 3 is provided with internal threaded holes. The circular frame 1 and the rear covering shell 2 are installed on the wall by using the protruding feet 3 and bolts;

[0020] The surface of the hollow frame 7 is provided with a slide groove 701, and a slide button 8 is slidably installed inside the slide groove 701. The slide button 8 is used to slide the main protective plate 9. When the slide button 8 slides, the slide groove 701 improves the sliding stability of the guide plate 1102, the main protective plate 9 and other components;

[0021] The gear rack transmission structure includes a linear hard plastic rack 12 fixed on the back of the main protective plate 9 and the auxiliary protective plate 10, and a central gear 13 rotatably mounted on one end of the surface of the circular inner plate 6. The central gear 13 and the two linear hard plastic racks 12 are all meshed. The central gear 13 and the linear hard plastic rack 12 enable the main protective plate 9 and the auxiliary protective plate 10 to maintain a synchronous relative motion relationship, realizing a function similar to a swing door, so that the user can operate it easily;

[0022] An elastic reset structure 11 is arranged inside the hollow frame 7, and the elastic reset structure 11 includes a coil spring 1101 installed on the inner wall of one side of the hollow frame 7, and a guide piece 1102 installed on the top of the coil spring 1101, and the bottom end of the guide piece 1102 is fixedly connected to the top of the main protective plate 9. When the user no longer applies force to the slide button 8, the main protective plate 9 or the auxiliary protective plate 10, the coil spring 1101 in the elastic reset structure 11 resets the guide piece 1102, the main protective plate 9 and the linear hard plastic rack 12 and other components, that is, the main protective plate 9 and the auxiliary protective plate 10 are closed again, and the screen surface of the digital thermometer and hygrometer body 4 is protected.

[0023] When the embodiment of the present application is in use, the staff first pushes the digital thermometer and hygrometer body 4 to be used into the rear covering shell 2. At this time, the outer edge of the screen surface of the digital thermometer and hygrometer body 4 coincides with the circular inner plate 6. Then, the rear covering shell 2 and the digital thermometer and hygrometer body 4 are fixed by bolting. At this time, the digital thermometer and hygrometer body 4 is fixed together with the protective frame. The staff still fixes the protective frame and the digital thermometer and hygrometer body 4 to the wall by wall embedding and bolting. When the user wants to operate the touch screen of the digital thermometer and hygrometer body 4, the user manually toggles the slide button 8 or one of the main protective plate 9 and the auxiliary protective plate 10. Taking the toggle of the slide button 8 as an example, the slide button 8 will drive the main protective plate 9 and the straight hard plastic rack 12 to move horizontally to the left until the main protective plate 9 is moved horizontally to the left. The plate 9 passes through the rectangular hollow cavity 5. During this process, since the straight hard plastic rack 12 and the center gear 13 are meshed with each other, the center gear 13 drives the other rack and the auxiliary protective plate 10 to move. At this time, the main protective plate 9 and the auxiliary protective plate 10 move away from each other until the main protective plate 9 and the auxiliary protective plate 10 no longer block the screen surface of the digital thermometer and hygrometer body 4. The user can perform normal touch operations. On the one hand, this design can provide effective screen protection to prevent the touch screen of the thermometer and hygrometer from being scratched, collided or otherwise damaged, which helps to extend the service life of the digital thermometer and hygrometer and reduce maintenance and replacement costs. In addition, the user can easily unfold or remove the main protective plate 9 and the auxiliary protective plate 10 as needed, which is convenient for the user to operate the thermometer and hygrometer without removing the entire protective frame and maintaining the sensitivity of the touch screen.
