[0023] Embodiment 1

[0024] A fast power-off-free meter replacement device, comprising: a base 1, a connecting seat 2, a terminal 3, a switching structure 4, a button 5, a top pipe 6 and a spring short-circuit group 7. The connecting seat 2 is fixed on the base 1. The terminal 3 is arranged inside the connecting seat 2. The spring short-circuit group 7 is arranged inside the connecting seat 2 on one side of the terminal 3. The switching structure 4 includes an elastic sliding rod 41, a top piece 42, a pushing piece 43 and a connecting rod 44. The button 5 is slidably arranged on the front end face of the connecting seat 2. The elastic sliding rod 41 is connected to the inner end of the button 5. The top piece 42 and the pushing piece 43 are rotatably arranged inside the connecting seat 2. The lower end of the top piece 42 is connected to the elastic sliding rod 41 through gear meshing. The lower end of the pushing piece 43 is in contact with the upper end of the top piece 42 through an arc surface. A push rod 431 contacting one side of the spring short-circuit group 7 is fixed at the lower end of the pushing piece 43. The two sides of the lower end of the connecting rod 44 are rotatably connected to the elastic sliding rod 41 and the connecting seat 2. The upper end of the connecting 44 is rotatably connected to a top rod 45. The top rod 45 is slidably arranged inside the top pipe 6. The top pipe 6 is slidably arranged on the upper end face of the connecting seat 2.

[0025] In this article, short-circuiting the electricity meter means that the spring short-circuit group 7 contacts the terminal 3 to conduct the current input end of one terminal 3 and the current output end of the other terminal 3, so as to bypass the electric energy metering device. The internal electricity consumption of residents continues. The purpose of short-circuiting is to replace the electric energy metering device.

[0026] As Figure 1 and Figure 2 shown, the working principle of the present utility model:

[0027] Stroke 1: By pressing the button 5, the internal elastic sliding rod 41 is pushed to move to the left, driving the top piece 42 to rotate clockwise upward, causing the pushing piece 43 to rotate counterclockwise upward. As a result, the push rod 431 on the pushing piece 43 moves away from the spring short-circuit group 7, making one end of the spring short-circuit group 7 that did not contact the terminal 3 originally become in contact with the terminal 3, so that both sides of the spring short-circuit group 7 contact the terminal 3, achieving short-circuiting. At this time, when the elastic sliding rod 41 moves to the left, it will drive the connecting rod 44 to rotate, and the top rod 45 at the upper end of the connecting rod 44 moves in the hole inside the top pipe 6;

[0028] Stroke 2: Continuing to press the button 5, the internal elastic sliding rod 41 is pushed to continue moving to the left. At this time, the top rod 45 reaches the uppermost end of the hole inside the top pipe 6, and then the top pipe 6 is pushed upward, pushing the electricity meter upward by a certain distance, so that the upper end of the terminal 3 withdraws from the connection hole at the lower end of the electricity meter by a certain distance, thereby reducing the pulling resistance and making the replacement more labor-saving.

[0029] When replacing a new electric energy meter, the lower end of the new electric energy meter is inserted into the terminal 3, and the top tube 6 is reset after the lower end of the meter presses down. The top tube 6 drives the connecting rod 44 to reset, and the connecting rod 44 drives the elastic sliding rod 41 to push the button 4 and the top plate 42 to reset. Under the action of the top plate 42, the push rod 431 pushes the spring short-circuit group 7 to move in the opposite direction, disengages from the terminal 3, and disconnects the short circuit. The operation is simple and labor-saving. Through the linkage structure, the electric meter is pushed up after short-circuiting, which reduces the resistance to pulling out and replacing, and can achieve fast and non-stop meter replacement.

[0030] As a further preferred embodiment, the elastic slide bar 41 includes a slide bar 41, a step bar 42 and a spring 1 43. The step bar 42 is fixed to the rear end of the inner side of the connection seat 2. The spring 1 43 is sleeved on the step bar 42. One end of the slide bar 41 is fixed to the button 5. The other end of the slide bar 41 contacts the spring 1 43. The connecting rod 44 includes a connecting rod 1 441 and a connecting rod 2 442. The lower end of the connecting rod 1 441 is rotatably connected to one side of the slide bar 41. The upper end of the connecting rod 2 442 is rotatably connected to the top rod 45. The lower end of the connecting rod 2 442 is rotatably connected to the inside of the connection seat 2. The upper end of the connecting rod 2 442 is rotatably connected to the middle of the connecting rod 1 441. Figure 2 As shown, the sliding rod 41 moves inward under the action of the button 5 to compress the spring 1 43, and drives the top plate 42 above, while driving the connecting rod 1 441 and the connecting rod 2 442 to move in conjunction, pushing the top rod 45 at the upper end to move upward.

[0031] As a further preferred embodiment, the top plate 42 includes an arc-shaped top head 421 at the upper end, and the push plate 43 includes an arc-shaped push head 432 at the lower end. The arc-shaped push head 432 is provided with an arc-shaped groove 433 on one side close to the arc-shaped top head 421. The push rod 431 is fixed to one end of the arc-shaped push head 431. The spring short-circuit group 7 includes a short-circuit plate 71 and a second spring 72. The push rod 431 contacts one side of the short-circuit plate 71, and the second spring 72 is located at the rear end of the short-circuit plate 71. Figure 3 and Figure 4 As shown, when the sliding rod 41 moves inward, the top plate 42 is driven to rotate through the gear meshing connection. After the arc-shaped top head 421 at the upper end of the top plate 42 rotates upward, the arc-shaped push head 432 of the push plate 43 rotates downward, causing the push rod 431 to move toward the front of the short-circuit plate 71. The short-circuit plate 71 moves forward under the action of the spring 72 to contact and fit the terminal 3.

[0032] As a further preferred embodiment, the terminal posts 3 are provided in four groups, a cable inlet 21 for connecting the terminal posts 3 is provided at the bottom of the connecting seat 2, a screw hole 22 is provided on the front end face of the connecting seat 2, and the disconnecting structure 4, button 5, top pipe 6 and spring short-circuit group 7 are symmetrically arranged in two groups.

[0033] As a further preferred embodiment, a baffle 8 is inserted into the front end of the connecting seat 2, and the baffle 8 is located on the front side of the screw hole 22. As Figure 1 shown, the baffle 8 can block the internally press-fitted terminal 3 on the inner side and the screw screwed into the screw hole 22, preventing electricity theft.

[0034] As a further preferred embodiment, an installation hole 23 is provided at the rear side of the connecting seat 2. The short-circuiting plate 71 is arranged in the installation hole 23. A protrusion 73 is provided at the rear end of the short-circuiting plate 71. The second spring 72 is sleeved on the protrusion 73 and the rear end of the second spring 72 contacts the bottom bracket 1. A groove 74 matching the terminal 3 is provided on the inner side of the short-circuiting plate 71. As Figure 6 shown, the installation hole 23 facilitates the positioning and installation of the short-circuiting plate 71. By means of the protrusion 73, during the process of positioning and compressing or positioning and stretching the second spring 72, the second spring 72 is ensured to be at a specified position; the groove 74 at the rear end increases the contact area between the short-circuiting plate 71 and the terminal 3, improving the stability of short-circuiting.
