[0018] The technical solutions of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present application, not all of them. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. The following embodiments and features in the embodiments may be combined with each other unless there is a conflict.

[0019] like Figures 1 - 3 The present embodiment provides an IoT-based smart water meter with a protective structure, including a smart water meter body 1 and a meter display cover 2. Connection holes 16 are provided on both sides of the meter display of the smart water meter body 1, and the connection holes 16 are circular holes; a pair of fixing plates 5 are fixed on the meter display cover 2, and a through hole 14 is provided on the fixing plates 5; and an installation mechanism is also included, which includes a sliding rod 6 that is slidably sleeved in the through hole 14, and one end of the sliding rod 6 is connected to an insertion rod 11 that is adapted to the connection hole 16.

[0020] The two sliding rods 6 are symmetrically distributed, and a positioning ring 10 is fixed on each of the two sliding rods 6. The positioning ring 10 is fixedly connected to the insertion rod 11, and the positioning ring 10 is slidably connected to the smart water meter body 1. It also includes a reset spring 9, and the two reset springs 9 are respectively sleeved on the outside of the sliding rod 6. The reset springs 9 are respectively connected to the fixed plate 5 and the positioning ring 10. The sliding rod 6 can be moved by the elastic force of the reset spring 9. The adjacent ends of the two sliding rods 6 are fixed with a toggle piece 7, and the end of the insertion rod 11 is provided with a chamfered portion 13. During installation, pinch the two toggle pieces 7 to bring the insertion rod 11 close to the fixed plate 5, and then align the insertion rod 11 with the connecting hole 16 and align it with it, slowly release the toggle piece 7, and the sliding rod 6 moves due to the elastic force of the reset spring 9, and then the insertion rod 11 is inserted into the connecting hole 16, and the installation is completed. It is simple to operate and easy to use.

[0021] In this embodiment, if Figure 1 As shown, a notch 4 is provided on the smart water meter body 1 at the same plane as the fixing plate 5. The notch 4 corresponds to the position of the fixing plate 5. When the meter display cover 2 is flipped over, part of the fixing plate 5 will extend into the notch 4 to avoid obstruction and realize the normal opening function.

[0022] In this embodiment, if Figure 2 and Figure 3 As shown, a positioning hole 15 connected to the through hole 14 is provided on the fixing plate 5, and a positioning block 8 adapted to the positioning hole 15 is fixed on the sliding rod 6. When the installation is completed, the positioning block 8 is located in the positioning hole 15 to limit the sliding rod 6 to prevent the sliding rod 6 from rotating with the display cover 2.

[0023] In this embodiment, if Figures 1 to 3As shown in the figure, a positive magnet 3 is fixed to the edge of the intelligent water meter body 1, and a negative magnet 12 that adsorbs to the positive magnet 3 is fixed to the lower surface of the edge of the meter display cover 2. This setting facilitates the opening and closing of the meter display cover 2. The intelligent water meter body 1 is fixedly installed, which is more convenient for meter reading compared to fixing with a lock catch and has high practicality.

[0024] The implementation principle of an Internet of Things-based intelligent water meter with a protection structure in an embodiment of this application is as follows: During installation, pinch the two toggle pieces 7 to make the insertion rod 11 approach the fixing piece 5. Then, align the insertion rod 11 with the connection holes 16 respectively and place them in alignment. Slowly release the toggle pieces 7. The sliding rod 6 moves due to the elastic force of the return spring 9, and thus the insertion rod 11 is inserted into the connection holes 16, completing the installation. The operation is simple and convenient to use.

[0025] By setting the notch 4, fixing piece 5, sliding rod 6, toggle piece 7, positioning block 8, return spring 9, positioning ring 10, insertion rod 11, chamfered portion 13, through hole 14, positioning hole 15, and connection hole 16, the return spring 9 pushes the connected sliding rod 6 through its elastic force, causing the insertion rods 11 on the sliding rod 6 to be inserted into the connection holes 16 on the intelligent water meter body 1 respectively. The sliding rod 6 is limited by the positioning hole 15 and the positioning block 8, so that the meter display cover is flipped through the insertion rod 11. When replacing or disassembling, just pinch the toggle pieces 7 with two fingers to make the insertion rod 11 move away from the connection hole 16 for disassembly. The operation is simple, convenient for replacement, and has high practicality.
