[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 6 The utility model provides a technical solution: a gas meter with a protective mechanism, the gas meter with a protective mechanism comprising: a gas meter body 1, a first limit block 3 and a rubber pad 4 are arranged on the surface of the gas meter body 1; a transparent protective shell 2, guide grooves 9 are opened on both sides of the transparent protective shell 2, circular notches 17 are opened on both sides of the transparent protective shell 2, a guide block 14 is arranged on the upper side of the transparent protective shell 2, a second limit block 12 is arranged in the transparent protective shell 2, a third rubber pad 13 is arranged on the outward side of the second limit block 12, and a second rubber pad 8 is arranged below the guide block 14.

[0027] When in use, first pull the circular limit block 10 outward, then align the second limit block 12 with the first limit block 3 and press downward until the limit rod 15 passes through the slot 5, thereby fixing the transparent protective shell 2 on the gas meter body 1, thereby preventing the transparent protective shell 2 from falling off, which may cause the gas meter to enter water and cause malfunctions. In addition, the transparent protective shell 2 can also effectively prevent the reading surface of the gas meter from being scratched, thereby reducing the occurrence of reading difficulties.

[0028] Embodiment 2

[0029] On the basis of Example 1, in order to prevent the transparent protective shell 2 from being displaced, a first limit block 3 is provided. The first limit block 3 is a square plate structure. The bottom of the first limit block 3 is fixedly connected to the surface of the gas meter body 1. The circular notch 17 is a cylindrical structure. The limit rod 15 can pass through the circular notch 17 and the notch 5. The outer end of the limit rod 15 is connected to the circular limit block 10. The diameter of the circular limit block 10 is greater than the diameter of the circular notch 17 and the notch 5. The circular limit block 10 cooperates with the spring 11 to limit the limit rod 15.

[0030] During specific use, the first limit block 3 cooperates with the second limit block 12 to prevent the transparent protective shell 2 from shifting to the left or right. At this time, the limit rod 15 passes through the circular notch 17 and the notch 5 to prevent the transparent protective shell 2 from shifting upward or downward.

[0031] Embodiment 3

[0032] On the basis of Example 2, in order to prevent water mist or dust from appearing on the inner surface of the transparent protective shell 2 or the reading table of the gas meter body 1, a guide groove 9 is provided. The width of the guide groove 9 is greater than the width of the connecting rod 16. The connecting rod 16 can pass through the guide groove 9. The third limit blocks 7 are located at both ends of the connecting rod 16. The third limit blocks 7 are provided in two groups. The two groups of third limit blocks 7 cooperate with the guide groove 9 to limit the connecting rod 16. The connecting rod 16 has a cylindrical structure. The middle section of the connecting rod 16 is connected to a square leather pad 6. The square leather pad 6 has a square plate structure and is fixedly connected to the connecting rod 16.

[0033] During specific use, since the width of the third limit block 7 is greater than the width of the guide groove 9, the width of the connecting rod 16 is less than the width of the guide groove 9, and one side of the square leather pad 6 is close to the inner surface of the transparent protective shell 2 and one side is close to the reading table of the gas meter body 1, the third limit block 7 is pulled up and down along the guide groove 9 to clean foreign objects that appear on the inner surface of the transparent protective shell 2 or the reading table of the gas meter body 1.

[0034] During actual use, pull the circular limit block 10 outward, and then align the second limit block 12 with the first limit block 3 and press downward until the limit rod 15 passes through the slot 5. The limit rod 15 passes through the slot 5 and the circular slot 17, and limits the relative displacement of the transparent protective shell 2 and the gas meter body 1 in the vertical direction. The first limit block 3 and the second limit block 12 cooperate with each other to limit the lateral displacement of the transparent protective shell 2. Pull the circular limit block 10 outward until the limit rod 15 is disengaged from the slot 5 and then move the transparent protective shell 2 upward to remove the transparent protective shell 2. A guide block 14 is provided on the upper side of the transparent protective shell 2 to guide water to flow to both sides, and the second rubber pad 8 cooperates with the rubber pad 4 to further improve the waterproofness. This avoids the problem of scratches on the reading surface of the gas meter during the use of a general gas meter, resulting in difficulty in reading, and component failure caused by water entering the gas meter.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
