[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The utility model provides an electromagnetic water meter with a protection function. The dial is arranged in the middle of a tube body, and two fixed disks are symmetrically installed on the tube body with the dial as the center. A protection sleeve is rotatably connected between the two fixed disks. A groove is provided on the outer wall of the protection sleeve corresponding to the dial. During daily use, the protection sleeve is rotated to stagger the groove and the dial. The protection sleeve protects the dial to prevent the dial from being worn during use.

[0025] Figure 1-4 The following is a schematic diagram of the structure of an electromagnetic water meter with a protective function according to the present invention. Figure 1-Figure 4 In this embodiment, an electromagnetic water meter with a protective function includes a pipe body 100, a protective sleeve 200 and a limit assembly 300.

[0026] Flanges 110 are installed at both ends of the tube body 100, a dial 120 is installed in the middle of the tube body 100, and two fixed plates 130 are symmetrically installed on the tube body 100 with the dial 120 as the center. A torsion spring 150 is installed on the side wall of the fixed plate 130, and the other end of the torsion spring 150 is connected to the inner wall of the protective sleeve 200.

[0027] The protective sleeve 200 is sleeved on the tube body 100, and a slot 210 is provided on the top of the protective sleeve 200, and the slot 210 corresponds to the position of the dial 120. The two ends of the protective sleeve 200 are rotatably connected to the side walls of the two fixed plates 130, and the diameter of the slot 210 is larger than the outer diameter of the dial 120. The side wall of the fixed plate 130 is provided with a guide groove 140, and the guide groove 140 is semicircular. The two ends of the protective sleeve 200 have guide plates 220, and the guide plates 220 are quarter-circular. The guide plates 220 extend into the guide groove 140. The outer wall of the protective sleeve 200 is installed with a fixing plate 230, and the side wall of the fixing plate 230 is provided with a limiting groove 240. In the normal state, the torsion spring 150 pushes the protective sleeve 200 to rotate downward, and the guide plate 2 The bottom end of 20 abuts against the bottom end of the guide groove 140. At this time, the slot 210 is staggered with the dial 120, and the protective sleeve 200 protects the dial 120. When it is necessary to observe or repair the dial 120, the hand grasps the protective sleeve 200 and flips it upward. The guide plate 220 moves inside the guide groove 140 and squeezes the torsion spring 150 until the top of the guide plate 220 abuts against the top of the guide groove 140. At this time, the slot 210 is perpendicular to the dial 120, and the dial 120 can be observed and repaired through the slot 210. After the observation is completed, the protective sleeve 200 is released, and the torsion spring 150 rebounds and pushes the protective sleeve 200 to flip downward until the bottom end of the guide plate 220 abuts against the bottom end of the guide groove 140, staggering the slot 210 with the dial 120.

[0028] The limiting assembly 300 includes a fixed frame 310 installed on the outer wall of the fixed disk 130, a slide groove 320 opened on the side wall of the fixed frame 310, a slide plate 330 slidably connected to the side wall of the slide groove 320, a spring 340 installed on the side wall of the slide plate 330 and a limiting plate 350 installed on the other side wall of the slide plate 330. The top of the limiting plate 350 has an arc surface 360. When the protective sleeve 200 rotates until the slot 210 is coaxial with the dial 120, the limiting plate 350 extends into the limiting groove 240. When the protective sleeve 200 rotates upward until the fixed plate 230 abuts against the limiting plate 350, as the protective sleeve 200 continues to rotate, the fixed plate 230 squeezes the limiting plate 350 along the arc surface 360 ​​to slide into the inside of the slide groove 320. The limit plate 350 pushes the slide plate 330 to slide into the slide groove 320 and squeezes the spring 340 until the top of the guide plate 220 abuts against the top of the guide groove 140. At this time, the spring 340 rebounds and pushes the slide plate 330 and the spring 340 to move toward the fixed plate 230 until the limit plate 350 passes through the limit groove 240. The straight edge of the limit plate 350 abuts against the inner wall of the limit groove 240 to limit the protective sleeve 200 to prevent the torsion spring 150 from pushing the protective sleeve 200 to rebound when the dial 120 is operated through the slot 210. After the operation is completed, the slide plate 330 is pulled to drive the limit plate 350 to be retracted into the slide groove 320, the limit plate 350 is separated from the limit groove 240, and the torsion spring 150 rebounds and pushes the protective sleeve 200 to rotate and reset.
