[0002] At present, after the construction of a building is completed, electrical engineering construction is still required, such as laying circuits, so that electrical equipment inside the building can be used. Due to the different voltages of various electrical equipment, in order to ensure the safety of electrical equipment during operation, it is also necessary to install a leakage protection device, commonly known as a leakage protector. A leakage protector is an electrical safety device that is installed in a low-voltage circuit. When a non-metallic single-phase grounding fault such as leakage current or electric shock occurs, and the specified operating current value is reached, the leakage protector will immediately operate within a specified time and automatically disconnect the power supply for protection.

[0003] However, during the maintenance of the existing leakage protector, if it is necessary to remove the leakage protector from a supporting object (such as a wall), the leakage protector is fixed to the supporting object with screws, which makes the disassembly and assembly of the leakage protector time-consuming and labor-intensive, and requires the use of tools to remove it, thereby reducing the convenience of maintenance of the leakage protector. In addition, although a protective shell cover is provided on the outside of the existing leakage protector to provide a certain degree of protection for the leakage protector, when the leakage protector needs to be disassembled, the protective shell cover after opening is prone to drooping under the action of gravity, requiring maintenance personnel to always lift the protective shell cover upwards by hand, which also affects the convenience of maintenance of the leakage protector.

[0032] like Figures 1 to 6 As shown together, the leakage protection device of the embodiment of the utility model includes a fixed plate 1, a protective frame 2 arranged on the fixed plate 1, and a transparent protective plate 3 movably connected to the protective frame 2; wherein, at least one leakage protector 5 is detachably mounted on the fixed plate 1, and the leakage protector 5 is accommodated in a cavity formed by the transparent protective plate 3, the protective frame 2 and the fixed plate 1; a mounting portion is arranged on the lower side of the transparent protective plate 3, and a plug-in portion 4 is arranged on the protective frame 2, and the mounting portion and the plug-in portion 4 cooperate to close or open the transparent protective plate 3; elastic driving portions 6 are arranged on both sides of the fixed plate 1, and transmission gears 302 are arranged at positions corresponding to the elastic driving portions 6 on both sides of the transparent protective plate 3, and when the limit between the plug-in portion 4 and the mounting portion is released, the elastic driving portion 6 and the transmission gear 302 can cooperate to open the transparent protective plate 3 and maintain the position of the opened transparent protective plate 3, thereby improving the convenience of repairing the leakage protector.

[0033] It can be seen that the number of leakage protectors 5 can be set according to specific application scenarios or requirements. The accompanying drawings show an example of setting two leakage protectors. The following takes one leakage protector as an example to provide a detailed structural description of the leakage protection device of the utility model.

[0034] Among them, the front end face of the fixed plate 1 is fixedly connected to the protective frame 2, and the upper front part of the protective frame 2 is rotatably connected with a transparent protective plate 3; a mounting plate 303 is arranged in the middle of the lower side of the transparent protective plate 3, and a plug-in part 4 is fixedly installed on the front end face of the mounting plate 303; the front end face of the fixed plate 1 is located on the inner side of the protective frame 2 and two leakage protectors 5 are installed in a left-right symmetrical manner; in addition, an elastic driving part 6 is arranged on the upper left and right sides of the front end face of the fixed plate 1; in addition, a plurality of threading openings can be opened at the front end face of the fixed plate 1 located inside the protective frame 2, and the figure shows an example of opening four threading openings 101, and the specific number of settings is not limited to the structure shown in the figure.

[0035] In addition, corresponding to one leakage protector 5, four slide rails 102 are arranged on the fixed plate 1, and a T-shaped slide groove is provided on the inner side of each slide rail 102; a clamping plate 103 is fixedly connected between the upper and lower slide rails 102 at corresponding positions, and a rectangular clamping interface 104 is provided on the clamping plate 103; in addition, two T-shaped sliders 504 are respectively provided on the left and right end surfaces of the leakage protector 5, and a clamping block 501 is provided between the two T-shaped sliders 504; two clamping blocks 501 are provided on the front end surface of the clamping block 501 in a vertically symmetrical shape. Rectangular openings 502, and each rectangular opening 502 is slidably connected to an elastic clip 503 and a spring. When the leakage protector 5 is installed on the fixed plate 1, the T-shaped slider 504 is slidably connected to the T-shaped slide groove on the slide rail 102 at the corresponding position, and the elastic clip 503 is clamped and limited with the rectangular clamping interface 104. When the leakage protector 5 needs to be removed, the two elastic clips 503 can be relatively squeezed by external force, thereby releasing the limit of the rectangular clamping interface 104 on the elastic clip 503, so that the leakage protector can be easily removed.

[0036] Specifically, the left and right end surfaces of the leakage protector 5 are symmetrically provided with two T-shaped sliders 504, and a clamping block 501 is provided in the middle of the left and right end surfaces of the leakage protector 5; the front end surface of each clamping block 501 is symmetrically provided with two rectangular openings 502, and each rectangular opening 502 is slidably connected to an elastic buckle 503, and each rectangular opening 502 is installed with a spring; when the leakage protector 5 is in an installed state on the fixed plate 1, the T-shaped slider 504 is slidably connected to the T-shaped slide groove provided on the slide rail 102, and the elastic buckle 503 is clamped with the rectangular clamping interface 104, so that the leakage protector 5 is effectively fixed on the front side of the fixed plate 1.

[0037] It can be seen that when two leakage protectors 5 are provided, eight slide rails 102 need to be fixedly installed on the front end face of the fixing plate 1 inside the protection frame 2 in a left-right symmetric manner, and a T-shaped chute is formed on the inner side surface of each slide rail 102; a clamping plate 103 is fixedly connected between every two upper and lower slide rails 102, and a rectangular clamping interface 104 is formed in the middle of the front end face of each clamping plate 103 for clamping with the elastic buckle 503.

The transmission gears 302 are driven to rotate by the driving rack, and then the transmission gears 302 and the rotating shaft 301 drive the transparent protection plate 3 to flip.

[0039] Specifically, two rotating connection blocks 201 are fixedly connected to the front side of the upper end face of the protection frame 2 in a left-right symmetric manner, and an L-shaped insertion plate 202 is fixedly connected to the middle of the bottom end face of the protection frame 2, and an insertion hole is formed in the front side of the right end face of the L-shaped insertion plate 202 for inserting with the limit insertion rod 405. A rotating shaft 301 is fixedly connected to the upper part of the transparent protection plate 3, and the rotating shaft 301 is rotatably connected to the two rotating connection blocks 201, and a transmission gear 302 is fixedly installed at both the left and right ends of the rotating shaft 301.

[0040] In a specific embodiment of the present invention, an installation plate 303 corresponding to the position of the insertion part 4 is provided at the lower end of the transparent protection plate 3, and the insertion part 4 is fixed on the installation plate 303; the insertion part 4 includes a rectangular sliding shell 401, a rectangular sliding block 402, an L-shaped pulling rod 403, a U-shaped limiting block 404 and a limit insertion rod 405; wherein, the rectangular sliding shell 401 is fixed on the installation plate 303, and the rectangular sliding block 402 is limited to move inside the rectangular sliding shell 401; the limit insertion rod 405 penetrates through the left side wall of the rectangular sliding shell 401 and is rotatably connected to the left end of the rectangular sliding block 402; the L-shaped pulling rod 403 penetrates through the right side wall of the rectangular sliding shell and is rotatably connected to the right end of the rectangular sliding block 402; the U-shaped limiting block 404 is fixedly connected to the right side of the installation plate 303 for limiting the L-shaped pulling rod 403.

[0041] Specifically, the rectangular sliding shell 401 is fixedly installed on the front end face of the mounting plate 303, and a rectangular sliding block 402 is slidably connected inside the rectangular sliding shell 401. A limiting insertion rod 405 is fixedly connected to the left end of the rectangular sliding block 402, and the limiting insertion rod 405 penetrates through the left side wall of the rectangular sliding shell 401.

A U-shaped limiting block 404 is fixedly connected to the right side of the front end face of the mounting plate 303, and the U-shaped limiting block 404 is used to limit the L-shaped pulling rod 403.

[0042] In another specific embodiment of the present invention, the elastic force driving part 6 includes a driving plate 601, a driving rack 602, a sliding sleeve 603, a guiding sliding rod 604 and a fixing block 605. Among them, the driving rack 602 is fixedly installed on the upper end face of the driving plate 601 and meshes with the corresponding transmission gear 302 on each side respectively. There are two sliding sleeves 603. The two sliding sleeves 603 are fixed to the bottom of the driving plate 601, and a guiding sliding rod 604 is slidably connected inside each sliding sleeve 603. The rear ends of the two guiding sliding rods 604 are fixedly connected to the fixing block, and a circular limiting block is provided at the front end of the guiding sliding rod 604. The fixing block is fixedly connected to the fixing plate 1, and a spring is sleeved outside the guiding sliding rod 604 between the fixing block and the sliding sleeve 603. When the transparent protection plate 3 and the protection frame 2 are in the closed state, the head end of the limiting insertion rod 405 is inserted into the insertion hole opened on the L-shaped insertion plate 202, and the spring outside the guiding sliding rod 604 is in a compressed state. When the head end of the limiting insertion rod 405 is separated from the insertion hole, the driving plate is used to drive the transmission gear 302 to open the transparent protection plate 3 under the action of the spring.

[0043] Specifically, a driving rack 602 meshing with the transmission gear 302 is fixedly installed on the upper end face of the driving plate 601, and two sliding sleeves 603 are fixedly installed on the bottom end face of the driving plate 601. A guiding sliding rod 604 is slidably connected inside each sliding sleeve 603, and the rear ends of the two guiding sliding rods 604 are fixedly connected to a fixing block 605, and the fixing block 605 is fixedly connected to the front end face of the fixing plate 1. A spring is sleeved outside each guiding sliding rod 604 between the fixing block 605 and the sliding sleeve 603, and a circular limiting block is provided at the front end of each guiding sliding rod 604. When the transparent protection plate 3 is in the closed state in front of the protection frame 2, the head end of the limiting insertion rod 405 is inserted into the insertion hole opened on the L-shaped insertion plate 202, and the spring outside the guiding sliding rod 604 is in a compressed state. Through the arrangement of the elastic force driving part 6, after the limiting insertion rod 405 is pulled out from the insertion hole opened on the L-shaped insertion plate 202, the transparent protection plate 3 can be automatically opened, and the lower end of the transparent protection plate 3 will not sag even under the action of gravity.

[0044] During the specific use of this embodiment, when installing the leakage protector, first, the four T-shaped sliders 504 on the leakage protector 5 are respectively slidably connected to the T-shaped chutes opened on the four slide rails 102. Then, continue to push the leakage protector 5 backward so that the elastic buckle 503 is snapped into the rectangular card interface 104, thereby effectively fixing the leakage protector 5 on the front side of the fixing plate 1. Then, fix the fixing plate 1 to the supporting object with screws.

[0045] When the leakage protector 5 needs to be repaired, first pull the L-shaped pull rod 403 to the right, and then snap the L-shaped pull rod 403 inside the C-shaped limit block 404, so that the L-shaped pull rod 403 is limited. And during the rightward movement of the L-shaped pull rod 403, it can drive the rectangular sliding block 402 and the limit insertion rod 405 to move to the right, so that the limit insertion rod 405 is pulled out from the insertion hole opened on the L-shaped insertion plate 202, so that the transparent protection plate 3 loses its limiting effect. Then, under the action of the spring force of the outer spring of the sliding sleeve 603 on the guiding slide rod 604, it drives the driving plate 601 and the driving rack 602 to move linearly forward, thereby driving the transmission gear 302, the rotating shaft 301 and the transparent protection plate 3 to rotate counterclockwise, so that the transparent protection plate 3 is automatically opened. Due to the action of the spring force, the lower end of the transparent protection plate 3 will not sag even under the action of gravity.

[0046] It can be seen that when the leakage protector 5 needs to be removed from the supporting object, the user only needs to manually pinch two adjacent elastic buckles 503 in the opposite direction at the same time, so that the elastic buckle 503 is separated from the rectangular card interface 104, and then the leakage protector 5 can be slid forward and removed.

[0047] According to the above leakage protection device of the present invention, it has the following advantages:

[0048] 1. Through the cooperation of the clamping block, elastic buckle, slide rail and clamping plate, when the leakage protector needs to be removed from the supporting object, people only need to manually pinch two adjacent elastic buckles in the opposite direction at the same time, so that the elastic buckle is separated from the rectangular card interface, and then the leakage protector can be slid forward and removed, thus making it more time-saving and labor-saving to remove the leakage protector from the supporting object, and it can be easily removed without the help of tools, improving the convenience of installing or removing the leakage protector;

[0049] 2. Through the setting of the elastic force driving part, after the limit insertion rod is pulled out from the insertion hole opened on the L-shaped insertion plate, the transparent protection plate can be automatically opened, and the lower end of the transparent protection plate will not sag even under the action of gravity, so that the maintenance personnel do not need to always hold the transparent protection plate up by hand, thus improving the convenience of the leakage protector during maintenance.
