[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a protective smart meter housing, including an observation shell 1, the outer wall of the observation shell 1 contacts with a connecting shell 2, the observation shell 1 and the connecting shell 2 and the electronic components constitute the entire smart meter housing, the top of the connecting shell 2 is fixedly connected with a fixing plate 3, the bottom inner wall of the fixing plate 3 is elastically connected with a wedge 5 through a reset spring 4, the wedge 5 is inclined, when squeezed, the wedge 5 will slide along the inner wall of the fixing plate 3, the outer wall of the wedge 5 is fixedly connected with a connecting rod 6, the connecting rod 6 can move the wedge 5 vertically, and a positioning mechanism is provided at the top of the observation shell 1.

[0032] Reference Figure 4-Figure 5 A square groove 8 is provided on the outer wall of the right end of the connecting shell 2, and a sealing airbag 9 is fixedly connected to the inner wall of the left end of the square groove 8. The sealing airbag 9 is made of rubber material and has air inside. When squeezed, it will expand and fit tightly to the inner wall of the surrounding square groove 8. A rubber plate 10 is fixedly connected to the outer wall of the left end of the observation shell 1. The rubber plate 10 has a certain hardness and matches the square groove 8. The rubber plate 10 is plugged into the inner wall of the square groove 8, and the outer wall of the sealing airbag 9 is in contact with the left end of the rubber plate 10.

[0033] Reference Figure 1-Figure 3The inner wall of the bottom end of the fixed plate 3 is fixedly connected to one end of the return spring 4. When the wedge block 5 moves upward, the return spring 4 will be compressed. When resetting, the elastic force of the return spring 4 is used to return the wedge block 5. The other end of the return spring 4 is fixedly connected to the top of the wedge block 5. The wedge block 5 is slidably connected to the inner wall of the fixed plate 3. The positioning mechanism includes a moving block 7, which is slidably connected to the top of the observation shell 1. The top of the observation shell 1 is provided with a notch, which can allow the moving block 7 to move laterally in its inner notch. The wedge block 5 contacts the side wall of the moving block 7, and the connecting rod 6 passes through and is slidably connected to the inner wall of the fixed plate 3. The fixed plate 3 is plugged into the outer wall of the moving block 7. The T-shaped groove on the fixed plate 3 matches the outer wall of the moving block 7, so that it can be initially plugged in for positioning.

[0034] Working principle: First, it is necessary to disassemble the observation shell 1 and the connecting shell 2 for maintenance or repair of the electronic components. Just move the connecting rod 6 upwards to move the wedge 5 upwards and compress the reset spring 4, so that the wedge 5 enters the fixed plate 3 and no longer blocks the moving block 7 from moving out of the T-slot of the fixed plate 3. Then move the moving block 7 to the left to separate the moving block 7 from the fixed plate 3, and then release the connecting rod 6 to use the reverse elastic force of the reset spring 4 to move the wedge 5 and the connecting rod 6 downward to reset them. Finally, separate the observation shell 1 and the connecting shell 2, and allow the rubber plate 10 to move out from the inner wall of the square groove 8 without squeezing the sealing airbag 9.

[0035] When the observation shell 1 and the connecting shell 2 need to be assembled and used, it is only necessary to first plug the rubber plate 10 into the square groove 8 and squeeze the sealing airbag 9, so that the sealing airbag 9 fits the inner wall of the square groove 8 to achieve a sealing effect, and prevent liquid from entering the interior through the gap between the observation shell 1 and the connecting shell 2. Then move the moving block 7 to the right to plug the moving block 7 into the T-slot of the fixed plate 3. During the plugging process, the side wall of the moving block 7 will squeeze the inclined surface of the wedge block 5, so that the wedge block 5 moves upward and compresses the reset spring 4. When the wedge block 5 is not squeezed, the reverse elastic force of the reset spring 4 will be used to reset the wedge block 5, so that the side wall of the wedge block 5 blocks the moving block 7, so that the moving block 7 cannot be moved out of the T-slot of the fixed plate 3, and the installation of the observation shell 1 and the connecting shell 2 is completed.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
