[0018] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The present embodiment provides an electric meter box with a protective structure, including a box body (not shown in the figure), a box cover 10, a lock hook assembly 20, a rotary push assembly 30 and a limit plate 50, wherein the box cover 10 is hingedly arranged on one side of the box body, the limit plate 50 is fixedly installed on the inner wall of the box body 10, and a slot 501 is provided on the side of the limit plate 50 away from the box body, the lock hook assembly 20 is arranged on the side of the box cover 10 facing the box body and can slide up and down along the box cover 10, the rotary push assembly 30 passes through the box cover 10 and can rotate relative to the box cover 10, and is used to push the lock hook assembly 20 so that the lock hook assembly 20 slides to the position of the slot 501.
[0019] When the box cover 10 is in a closed state on one side of the box body, the lock hook assembly 20 is hooked on the inner side of the limit plate 50, thereby limiting the box cover 10, so that the box cover 10 cannot be rotated to open, so as to avoid the occurrence of electricity theft. When it is necessary to open the box cover 10 to inspect and maintain the electric meter in the box body, the staff can rotate the rotary push assembly 30. When the rotary push assembly 30 rotates, it pushes the lock hook assembly 20 to slide along the side wall of the box cover 10 to the position of the slot 501, so that the limited state of the box cover 10 is released. Then the staff can pull the box cover 10, and the box cover 10 rotates relative to the box body to open the box body, and the lock hook assembly 20 passes through the slot 501.
[0020] See also Figure 3 , Figure 4 as well as Figure 6In one embodiment, a vertically distributed first slide rail 101 is fixedly provided on one side of the box cover 10 facing the box body, the rotary push assembly 30 includes a rotating shaft 302 and an eccentric wheel 304, the rotating shaft 302 passes through the box cover 10 and rotates with the box cover 10, the eccentric wheel 304 is fixedly arranged on the rotating shaft 302 at one end of the box cover 10 facing the box body, the locking hook assembly 20 includes a slider 201, a push rod 202 and a locking hook 205, the slider 201 is slidably matched with the first slide rail 101, one end of the locking hook 205 is connected to one side of the slider 201, and the other end extends to the inner side of the limit plate 50 and is attached to the limit plate 50, the upper end of the push rod 202 is fixedly connected to the bottom of the slider 201, and the lower end of the push rod 202 is against the circumferential side wall of the eccentric wheel 304.
[0021] When the box cover 10 is in a closed state on one side of the box body, the eccentric wheel 304 naturally droops due to gravity, and the top rod 202 and the slider 201 are simultaneously in the lowest position due to gravity. The locking hook 205 is hooked at a certain position on the inner side of the limit plate 50, so that the box cover 10 is in an unopenable state. When the electric meter in the box body needs to be inspected and maintained, the staff rotates the rotating shaft 302. When the rotating shaft 302 rotates, the top rod 202 is pushed, so that the slider 201 slides up along the first slide rail 101. When the slider 201 slides up, it drives the locking hook 205 to move up. After the rotating shaft 302 rotates to a predetermined angle (for example, 20°), the locking hook 205 just moves up to the inside of the slot 501. Then the staff pulls the box cover 10, and the box cover 10 rotates outward compared to the box body, thereby opening the box body. When the box cover 10 rotates, it drives the locking hook 205 so that the locking hook 205 passes through the slot 501.
[0022] See also Figure 4 as well as Figure 5 In one embodiment, the rotating shaft 302 is located at one end of the box cover 10 away from the box body and is fixedly provided with a knob 301. The setting of the knob 301 facilitates the turning operation of the rotating shaft 302.
[0023] See also Figure 6 In one embodiment, a socket 203 is provided on one side of the slider 201, one end of the locking hook 205 extends into the socket 203 and is connected to the inner wall of the socket 203 through an elastic member 204, the other end of the locking hook 205 extends to the inner side of the limiting plate 50 and is attached to the limiting plate 50, and an inclined surface is provided at the other end of the locking hook 205 away from the limiting plate 50, and the elastic member 204 is used to provide elastic support for the locking hook 205.
[0024] After the staff has finished inspecting and maintaining the electric meter, they can rotate the box cover 10 in the opposite direction so that the box cover 10 is closed again on one side of the box body. At this time, the inclined surface of the lock hook 205 acts on the limit plate 50, and the limit plate 50 pushes the lock hook 205 to move toward the inside of the socket 203. The elastic member 204 is adaptively compressed until the lock hook 205 passes over the limit plate 50. The elastic member 204 pushes the lock hook 205 to move toward the outside of the socket 203, and then hooks to the inside of the limit plate 50, thereby limiting the box cover 10 again.
[0025] In one embodiment, the elastic member 204 may be a spring or a metal spring, which is not limited here.
[0026] See also Figure 2 as well as Figure 5 In one embodiment, a second slide rail 305 is fixedly provided on one side of the eccentric wheel 304 in the radial direction, and a slide groove compatible with the second slide rail 305 is opened at one end of the rotating shaft 302. A driving component 40 is arranged in the rotating shaft 302, and the driving component 40 is used to drive the eccentric wheel 304 to slide relative to the rotating shaft 302, so that the initial position of the eccentric wheel 304 changes compared with the rotating shaft 302. When the initial position of the eccentric wheel 304 changes, the initial heights of the slider 201 and the locking hook 205 will also change synchronously. Therefore, when the rotating shaft 302 is subsequently rotated to adjust the locking hook 205 to the inner side of the notch 501, the required rotation angle of the rotating shaft 302 will also change. Through this arrangement, the predetermined angle of the rotating shaft 302 can be adjusted when the box cover 10 is opened, thereby avoiding the leakage of the current predetermined angle data causing the box cover 10 to be opened without reason, thereby improving the anti-theft effect.
[0027] See also Figure 5 In one embodiment, a channel 303 extending axially therethrough is provided in the rotating shaft 302, and the driving assembly 40 includes a gear 401 and a rack 402. The gear 401 is rotatably disposed inside the channel 303, and the rack 402 is fixedly disposed on the side wall of the second slide rail 305 and meshes with the gear 401.
[0028] After the preset angle data of the current rotating shaft 302 is leaked, the staff can rotate the gear 401, and through the meshing action of the gear 401 and the rack 402, the second slide rail 305 is driven to slide relative to the rotating shaft 302, thereby driving the eccentric wheel 304 to move relative to the rotating shaft 302. When the eccentric wheel 304 moves, the top rod 202 that abuts against the eccentric wheel 304 drives the slider 201 to move up and down adaptively, thereby adjusting the initial height of the lock hook 205. After the initial height of the lock hook 205 changes, the rotating shaft 302 rotates to adjust the lock hook 205 to the angle inside the slot 501, thereby preventing unauthorized personnel from opening the box cover 10 to steal electricity.
[0029] To facilitate understanding of the corresponding relationship between the rotation angle of the gear 401, the moving distance of the lock hook 205, and the angle at which the rotating shaft 302 rotates to open the box cover 10, the distance is described as follows: For example, when the gear 401 rotates upward by 5°, the eccentric wheel 304 moves down by 1 cm compared to the rotating shaft 302 through the meshing transmission action of the gear 401 and the rack 402, and the corresponding push rod 202, slider 201 and lock hook 205 move down by 1 cm. Then, the angle when the rotating shaft 302 rotates to readjust the lock hook 205 to the inner side of the slot 501 increases by 5°, that is, 25°.
[0030] When the box cover 10 is in the closed state at one side of the box body, the lock hook assembly 20 is hooked on the inner side of the limit plate 50, thereby limiting the box cover 10 so that the box cover 10 cannot be rotated to open, so as to avoid the occurrence of electricity theft. When the box cover 10 needs to be opened to inspect and maintain the electric meter in the box body, the staff can rotate the rotating push assembly 30. When the rotating push assembly 30 rotates, the lock hook assembly 20 is pushed to slide along the side wall of the box cover 10 to the position of the notch 501, so that the limited state of the box cover 10 is released. Then the staff can pull the box cover 10, and the box cover 10 rotates relative to the box body to open the box body, and the lock hook assembly 20 passes through the notch 501 accordingly. Compared with the prior art, the box cover 10 is limited by the cooperation of the lock hook assembly 20 and the limit plate 50, so as to achieve the purpose of preventing the electric meter from being stolen, and the lock hook assembly 20 is driven to move to the position of the inner side of the notch 501 in cooperation with the rotating push assembly 30, so as to realize the convenient opening of the box cover 10.
[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any reference numerals in the claims should not be regarded as limiting the claims involved.
