Description

Technical Field

[0001] This utility model relates to the field of bed call bell technology, specifically a bed call bell based on millimeter-wave radar. Background Technology

[0002] Millimeter-wave radar detects and senses targets by emitting electromagnetic waves in the millimeter-wave frequency band. Installed in spaces such as bathrooms, living rooms, and bedrooms, it assists in detecting accidental falls / bed falls. It requires no wearing and is used seamlessly. When it detects that an elderly person has gotten out of bed, fallen, or exhibited other abnormal behavior, the radar transmits a signal to relevant devices or platforms, triggering an alarm. It can also connect to a call system so that the elderly person can quickly make a call when needed.

[0003] Existing millimeter-wave radar bed call bells are usually installed on the ceiling or wall inside the room. However, when installing the bed call bell, it is simply inserted into the mounting base, and there is no limiting device inside the mounting base to stop the call bell. After long-term use, the call bell is prone to falling and getting damaged, so it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a bed call bell based on millimeter-wave radar to solve the problems mentioned in the background art.

[0006] The limiting mechanism includes a fixed frame, which is fixedly connected to the periphery of the connecting seat. A slide rod is slidably connected to the inner side of the fixed frame. A pull plate is fixedly connected to the outer side of the slide rod. A fixed disc is fixedly connected to the periphery of the slide rod. A hemispherical block is fixedly connected to the inner side of the slide rod. A spring is sleeved around the periphery of the slide rod.

[0007] Preferably, there are two arc-shaped plates, which are fixedly connected to the left and right sides of the outer periphery of the connecting seat. The arc-shaped plates are used in conjunction with bolts to enable the connecting seat to be installed on the wall. The connecting seat makes it convenient for staff to install the call bell body.

[0008] Preferably, the outer side of the spring is fixedly connected to the inner side of the fixed frame, and the inner side of the spring is fixedly connected to the outer side of the fixed plate. Through the elastic force of the spring, the spring can drive the sliding rod and the hemispherical block to move through the fixed plate, so that the hemispherical block is inserted into the rotating plate and the rotating plate and the connecting plate are limited.

[0009] Preferably, the connecting seat has an arc-shaped groove inside that corresponds to the position of the rotating plate, and the rotating plate is slidably connected inside the arc-shaped groove. Through the arc-shaped groove, the rotating plate can be inserted into the inside of the connecting seat. By rotating the call bell body, the rotating plate can rotate inside the connecting seat. The rotating plate can limit the position of the call bell body, so that the call bell body can be initially installed inside the connecting seat.

[0010] Preferably, the inner side of the rotating plate at the top of the connecting plate has a circular hole corresponding to the position of the hemisphere, and the hemisphere is inserted into the inner side of the circular hole. Through the circular hole, the hemisphere can be inserted into the rotating plate to limit the position of the rotating plate.

A slide rod 33 is slidably connected to the inner side of the fixed frame 31. A pull plate 32 is fixedly connected to the outer side of the slide rod 33. A fixed plate 35 is fixedly connected to the periphery of the slide rod 33. A hemispherical block 36 is fixedly connected to the inner side of the slide rod 33. A spring 34 is sleeved around the periphery of the slide rod 33.

[0026] Furthermore, there are two curved plates 5, which are fixedly connected to the left and right sides of the outer periphery of the connecting seat 2 respectively. The curved plates 5 are used in conjunction with bolts 4 to enable the connecting seat 2 to be installed on the wall. The connecting seat 2 makes it convenient for staff to install the call bell body 1.

[0027] Furthermore, the outer side of the spring 34 is fixedly connected to the inner side of the fixed frame 31, and the inner side of the spring 34 is fixedly connected to the outer side of the fixed plate 35. Through the elastic force of the spring 34, the spring 34 can drive the slide rod 33 and the hemispherical block 36 to move through the fixed plate 35, so that the hemispherical block 36 is inserted into the rotating plate 6, thereby limiting the rotation plate 6 and the connecting plate 7.

[0028] Furthermore, the connecting seat 2 has an arc-shaped groove inside that corresponds to the position of the rotating plate 6, and the rotating plate 6 is slidably connected inside the arc-shaped groove. Through the arc-shaped groove, the rotating plate 6 can be inserted into the inside of the connecting seat 2. By rotating the call bell body 1, the rotating plate 6 can rotate inside the connecting seat 2. The rotating plate 6 can limit the call bell body 1, so that the call bell body 1 can be initially installed inside the connecting seat 2.

[0029] Furthermore, a circular hole corresponding to the position of the hemispherical block 36 is opened on the inner side of the rotating plate 6 at the top of the connecting plate 7, and the hemispherical block 36 is inserted into the inner side of the circular hole. Through the circular hole, the hemispherical block 36 can be inserted into the rotating plate 6 to limit the position of the rotating plate 6.

[0031] In actual operation, when this device is used, the connecting seat 2 is installed to the wall by bolt 4, the connecting plate 7 and the rotating plate 6 are inserted into the inner side of the connecting seat 2, and the call bell body 1 is rotated so that the rotating plate 6 can press the hemispherical block 36, so that the hemispherical block 36 can press the spring 34 through the fixed plate 35. When the rotating plate 6 does not press the hemispherical block 36, the elastic force of the spring 34 can drive the slide rod 33 and the hemispherical block 36 to move through the fixed plate 35, so that the hemispherical block 36 is inserted into the rotating plate 6, limiting the rotating plate 6 and the connecting plate 7, so that the call bell body 1 is not easy to fall off and be damaged when it is vibrated during use.
