[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 3The utility model provides an embodiment: a protective device for an electric meter box, comprising a box body 1. The box body 1 can be made of PC+ABS, SMC fiberglass or stainless steel, all of which have good mechanical strength and protective performance. A controller 2 is fixedly connected to the inside of the box body 1. A knife switch is provided on the front side of the controller 2. When the knife switch is downward, all power supplies are cut off. A box door 3 is hinged on the front side of the box body 1. A password lock 4 is fixedly connected to the front of the box door 3. The opening and closing of the box door 3 can be controlled by the password lock 4. A fixed frame 5 is fixedly connected to the front of the box door 3. The fixed frame 5 can protect the outside of the password lock 4, reduce the situation where the password lock 4 is subjected to external impact, and thus reduce the possibility of damage to the password lock 4.

[0034] Reference Figure 4-Figure 5 The interior of the fixed frame 5 is plugged with a buffer frame 6, and the fixed frame 5 and the buffer frame 6 are both sleeved on the outside of the password lock 4. The buffer frame 6 can perform linear motion in the front and rear directions inside the fixed frame 5. The back of the buffer frame 6 is fixedly connected with a buffer elastic member 7, and the rear end of the buffer elastic member 7 is fixedly connected to the front of the box door 3. When the buffer frame 6 is hit by an external object and moves to the rear side, the buffer elastic member 7 can be squeezed so that the buffer elastic member 7 is compressed to generate elastic potential energy. The interior of the buffer frame 6 is hinged with a buffer door 8, and the outer wall of the buffer door 8 fits with the inner wall of the buffer frame 6. The bottom end of the buffer door 8 is hinged to the inside of the buffer frame 6, and the upper end of the buffer door 8 can be rotated to the front side, thereby opening the buffer door 8, so that the staff can operate the password lock 4.

[0035] By cooperating with the fixed frame 5, the buffer frame 6 and the buffer door 8, the outer side of the password lock 4 can be protected to prevent foreign objects from directly hitting the password lock 4 and causing damage to the password lock 4. When the outside hits the buffer door 8 and the buffer frame 6 on the outside, the buffer frame 6 can be pushed to move backward, thereby squeezing the buffer elastic part 7, so that the buffer elastic part 7 is compressed to generate elastic potential energy. The impact force is buffered and offset by the generated elastic potential energy, thereby extending the service life of the buffer frame 6 and the buffer door 8.

[0036] A fixing unit is provided above the buffer door 8, and the fixing unit includes a groove 81. The groove 81 is opened on the front of the buffer door 8. The inner bottom surface of the groove 81 is fixedly connected to a fixing elastic member 82. The upper end of the fixing elastic member 82 is fixedly connected to an L-shaped clamping block 83. When the L-shaped clamping block 83 is forced to move downward, it can squeeze the fixing elastic member 82, so that the fixing elastic member 82 is compressed to generate elastic potential energy. When the force applied to the L-shaped clamping block 83 disappears, the L-shaped clamping block 83 can move upward and reset under the action of the elastic potential energy of the fixing elastic member 82. The block 83 is slidably connected to the groove 81, and the groove 81 can guide and limit the movement of the L-shaped clamping block 83, so that the L-shaped clamping block 83 can only perform linear motion in the up and down directions. The upper end of the L-shaped clamping block 83 passes through the buffer door 8, and a clamping groove 84 is provided on the inner top surface of the buffer frame 6. The upper end of the L-shaped clamping block 83 is clamped with the inside of the clamping groove 84. In the initial state, the upper end of the L-shaped clamping block 83 is clamped with the inside of the clamping groove 84. At this time, the buffer door 8 can be fixed, so that the buffer door 8 and the buffer frame 6 can cooperate to protect the front side of the password lock 4.

[0037] An anti-static rod 9 is provided on the front side of the buffer door 8. The front end of the L-shaped clamping block 83 is fixedly connected to the anti-static rod 9. The staff can pull the L-shaped clamping block 83 downward through the anti-static rod 9 to contact the clamping fixation of the buffer door 8. At the same time, when the staff's hand touches the anti-static rod 9, the static electricity on the staff can be eliminated, thereby preventing the static electricity carried by the staff from causing damage to the sensitive electronic components inside the box 1.

[0038] When the staff needs to operate the password lock 4 to open the box door 3, they must first pull down the anti-static rod 9 to release the clamping fixation of the buffer door 8, so as to open the buffer door 8 and operate the password lock 4. In this process, the static electricity on the staff will naturally be eliminated, preventing the staff from working with static electricity and improving the safety of maintenance.

[0039] Reference Figure 3 and Figure 6The left inner wall surface of the box body 1 is fixedly connected with a fixing plate 10, and the upper surface of the fixing plate 10 is provided with a circular plate 11, and the bottom surface of the circular plate 11 is fixedly connected with a screw 12. When the circular plate 11 rotates, the screw 12 can be driven to rotate synchronously, and the bottom end of the screw 12 passes through the fixing plate 10, and the screw 12 is threadedly connected to the fixing plate 10. When the screw 12 rotates, it can perform linear motion in the up and down directions relative to the fixing plate 10. The bottom end of the screw 12 is fixedly connected with a rubber head 13, which can avoid direct hard contact between the screw 12 and the knife switch of the controller 2, thereby extending the service life of the switch. When the staff needs to inspect the inside of the box body 1 after opening the box door 3, they can twist the circular plate 11 to drive the screw 12 to move downward, so that the rubber head 13 moves downward to push the knife switch to cut off all power supplies. At this time, the rubber head 13 can limit the knife switch to prevent accidental power supply.

[0040] Working principle: When the staff needs to open the box door 3 to inspect the inside of the box body 1, they can pull the static elimination rod 9 to drive the L-shaped clamping block 83 to move downward, so that the L-shaped clamping block 83 moves downward out of the card slot 84, and releases the clamping fixation of the buffer door 8, so that the buffer door 8 can be rotated forward to open the buffer frame 6, so that the staff can operate the password lock 4 and open the box door 3 for inspection. In the process of pulling the static elimination rod 9, the static electricity on the working personnel can be removed to prevent the staff from operating with static electricity. Through the cooperation of the set fixed frame 5, buffer frame 6 and buffer door 8, the outside of the password lock 4 can be protected to prevent foreign objects from hitting the password lock 4 and affecting the opening of the box door 3. After the box door 3 is opened, the staff can twist the round plate 11 to drive the screw 12 to move downward, so that the rubber head 13 can control the knife switch of the controller 2 to turn off, cut off all power supplies, and limit the switch to avoid accidental power supply.

[0041] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
