Referring to fig. 1-3, an ammeter extension module fastening device includes:

An expansion module 1 comprising a module body 11, a positioning slot 12 and a connecting slot 13, wherein,

Positioning grooves 12 provided at four sides of the module body 11;

A connecting groove 13 provided on a side wall of the module body 11, the connecting groove 13 being provided between the positioning grooves 12, the connecting groove 13 being a cylindrical groove;

The connecting plate 2 comprises a plate body 21, clamping blocks 22, a mounting groove 23 and a threaded column 24, and is arranged in the connecting groove 13, wherein the clamping blocks 22 are arranged at two ends of the plate body 21, the mounting groove 23 is arranged at one end of the plate body 21 far away from the supporting block 4, the threaded column 24 is arranged in the mounting groove 23, the clamping blocks 22 are cylinders, and the diameter of the clamping blocks 22 is smaller than the inner diameter of the connecting groove 13;

Based on the above, the connecting groove 13 cooperates with the connecting plate 2 so that the two expansion modules 1 are connected by the connecting plate 2 and so that the connecting plate 2 can only move in the direction of the connecting groove 12, the other movement directions being limited, as is the expansion modules 1.

As shown in fig. 2 and 4, the spring clip 3 includes a metal spring 31, a mounting hole 32 and a toggle block 33, wherein,

The metal spring plate 31 is arranged in the mounting groove 23 and extends to the inside of the positioning groove 12, the stirring block 33 is arranged at the top end of the metal spring plate 31, the mounting hole 32 is arranged on the outer surface of the metal spring plate 31, the threaded column 24 penetrates through the mounting hole 32, and the metal spring plate 31 is a V-shaped metal spring plate;

A supporting block 4 disposed outside the screw column 24, the supporting block 4 including a block 41, and mounting rings 42 disposed at both upper and lower ends of the block 41;

An internal screw cap 5 which is provided at one end of the screw column 24 and is adapted to the screw column 24;

Based on the above, the elastic sheet fixture block 3 is sleeved outside the threaded column 24, and after the elastic deformation of the metal elastic sheet 31 is caused, the metal elastic sheet 31 is clamped into the positioning groove 12, and in this process, the metal elastic sheet 31 plays a limiting role on the connecting plate 2, so that the connecting plate 2 cannot move along the direction of the connecting groove 13, when the expansion module 1 is fixed on the fixed bracket of the power distribution cabinet, the connecting groove 13 limits the movement direction of the connecting plate 2, the positioning groove 12 and the connecting plate 2 are mutually matched, and the movement mode of the elastic sheet fixture block 3 is limited, and the three are mutually matched, so that the connection fixation between the expansion modules 1 is realized, two or more expansion modules 1 can form a whole, and the supporting block 4 plays a supporting role, so that the bearing capacity of the connecting plate 2 is increased.

In practical use, the elastic sheet clamping block 3 is sleeved outside the threaded column 24 by clamping the connecting plate 2 into the connecting groove 13, and in the process, the toggle block 33 is pressed to enable the two sides of the metal elastic sheet 31 to be close to the middle, namely elastic deformation is generated, and when the metal elastic sheet 31 moves to the position of the positioning groove 12, the toggle block 33 is loosened, so that the metal elastic sheet 31 is clamped into the positioning groove 12 under the action of elastic force of the toggle block, and the function of connecting the two expansion modules 1 is realized;

When one of the expansion modules 1 needs to be disassembled, the stirring block 33 is squeezed again to enable the metal elastic sheet 31 to be elastically deformed, and then the elastic sheet clamping block 3 can be pulled to enable the elastic sheet clamping block to move along the direction of the threaded column 24, namely, the elastic sheet clamping block 3 is simultaneously separated from the expansion modules 1 and the connecting plate 2, and the connecting plate 2 is pulled out to achieve the effect of separating the two expansion modules 1.

In the second embodiment, on the basis of the first embodiment, the supporting block 4 is detached, and the internal thread cap 5 is directly arranged at one end of the thread column 24, so that the internal thread cap 5 is in contact with the elastic sheet clamping block 3, as shown in fig. 5, at this time, the supporting block 4 is absent in the device, the bearing capacity is weakened, but the capability of fastening the two expansion modules 1 is inconvenient, and compared with the first embodiment, the structure lacking the supporting block 4 can be easier in installation, and the operation procedure is reduced.

In the third embodiment, the female screw cap 5 is detached on the basis of the first embodiment, as shown in fig. 6, the device only realizes connection and fixation between the expansion modules 1 by the cooperation among the expansion modules 1, the connecting plate 2 and the elastic sheet clamping blocks 3 due to the lack of the female screw cap 5, and compared with the second embodiment, the embodiment lacks the female screw cap 5, so that the tightness degree between the elastic sheet clamping blocks 3 and the connecting plate 2 is reduced, but the device is simpler in mounting process, more convenient to use in actual use and easier to detach.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
