[0046] In order to facilitate the support of the unfolded protective cover 5, a fixed plate 10 is provided. The fixed groove 9 is a square plate structure. The fixed plate 10 can be displaced in the fixed groove 9. A movable groove 26 is opened on the side of the fixed groove 9. The movable groove 26 is provided with two groups. The two groups of movable grooves 26 are symmetrically distributed about the fixed groove 9. The fixed groove 9 is provided with a positioning spring 27.

Through the movement of the fixed plate 10 in the fixed groove 9, the arc-shaped clamping plate 39 provided on the inner side of the fixed plate 10 can be used to push one end of the positioning clamping plate 31, so that one end of the positioning clamping plate 31 can be conveniently clamped in the arc-shaped clamping plate 39, so that the fixed plate 10 can be stored in the fixed groove 9. The protective plate 37 cooperates with another set of auxiliary plates 33 to cover the end surface of the movable groove 26 to prevent larger dust from entering the movable groove 26. After the fixed plate 10 is stored in the fixed groove 9, the end surface of the fixed groove 9 can be filled.

[0048] In actual use, when it is necessary to use the meter body 1 to check the gas consumption flow, the positioning rod 7 can be rotated to disengage the positioning rod 7 from the positioning ring 4, so that the protective cover 5 can be rotated out from the side of the meter body 1, and the display screen 2 on the meter body 1 can be exposed, so that the residents can conveniently check the gas consumption value. When it is not necessary to check, the protective cover 5 can cover the display screen 2, and the positioning frame 8 set inside the protective cover 5 can be used to improve the protection effect of the display screen 2. This avoids the general gas consumption meter being mainly installed in the kitchen. Due to the long-term use of the kitchen, there is a lot of oil smoke, which may cause the display screen 2 on the gas consumption meter to be attached with a large amount of kitchen grease. The long-term accumulation of grease will affect the residents' observation of the display screen 2. In addition, some elderly people living at home cannot think of cleaning the display screen 2 frequently, and on the other hand, it is more inconvenient for the elderly to observe the display screen 2 with a large amount of grease.
