DETAILED DESCRIPTION

[0027] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] Refer to the instruction manual Figure 1-7 , a quick-install outdoor explosion-proof electric energy meter according to an embodiment of the present invention, such as Figure 1-2 As shown, it includes an electric energy meter body 1, and a positioning frame 2 is fixedly installed on one side of the electric energy meter body 1;

[0029] A connection line limiting mechanism 3 is fixedly installed inside the electric energy meter body 1, and a blocking mechanism 4 is fixedly installed at the bottom of the electric energy meter body 1;

[0030] Reference Figure 1 and Figure 4-5 As shown, the connection line limiting mechanism 3 includes a plurality of wire frames 31 fixedly installed inside the electric energy meter body 1, a wiring seat 32 is fixedly installed on one side of the plurality of wire frames 31, a connection type press frame 33 is rotatably installed on one side of the wire frame 31 close to the wiring seat 32, a limit type roller 34 is rotatably installed on the bottom of the connection type press frame 33, an insulating pressing plate 35 is fixedly installed at the horizontal center line position of the connection type press frame 33, and the insulating pressing plate 35 is arranged in a protruding arc shape on one side close to the wiring seat 32. At the same time, a wire groove arranged in a through shape is opened at the bottom of the electric energy meter body 1, and the wire groove and the wire frame 31 are arranged in a mutually connected state. In actual use, the external connection line passes through the wire groove and extends into the inner cavity of the wire frame 31, and is inserted It is connected to one side of the terminal block 32, and then the inclined connecting pressure frame 33 is gradually deflected downward until the insulating pressure plate 35 is pressed on the terminal block 32 and the connecting wire, so as to achieve the purpose of pressing the connecting wire. The fixing method of the connecting wire is very convenient, and the connecting pressure frame 33 is always installed inside the wire frame 31 in an inclined state under normal conditions, and the position of the limiting roller 34 under normal conditions is close to the bottom of the wire frame 31. According to the different sizes of the connecting wires, the connecting pressure frame 33 and the limiting roller 34 can be pressed downward according to the different overall positions, so that the connecting wires of different sizes can be limited and pressed synchronously, so that the adaptability of the device is higher and more convenient for practical use.

[0031] Among them, combined Figure 6As shown, the top of the wire frame 31 is threadedly connected with a threaded screw 39, and one end of the threaded screw 39 extending into the inner cavity of the wire frame 31 is rotatably installed with a limiting pressure block 38. The limiting pressure block 38 is always arranged in a mutually fitting state with the limiting roller 34 under normal conditions. A guide frame 36 is fixedly installed on one side of the connecting pressure frame 33, and a first telescopic spring 37 fixedly connected to the wire frame 31 is fixedly installed on the outer surface of the guide frame 36. The purpose of this arrangement is to enable the limiting pressure block to be rotated by rotating the threaded screw 39. 38 generates pressure on the limiting roller 34, which then pushes the connecting type pressure frame 33 to deflect as a whole towards the terminal block 32, and after the insulating pressure plate 35 is pressed tightly against the connecting wire and the terminal block 32, the position of the limiting roller 34 is synchronously limited and pressed by fixing the position of the limiting pressure block 38 and the threaded screw 39, so that the deflection angle of the connecting type pressure frame 33 remains unchanged, making the overall adjustment method very convenient, which is very convenient and fast when connecting multiple connecting wires, and is more conducive to improving work efficiency.

[0032] Further, see Figure 5-6As shown, a limiting slide 310 is fixedly installed on one side of the wire frame 31, an auxiliary limiting ring 311 is slidably installed on one side of the limiting slide 310, a connecting bracket 312 is fixedly installed on one side of the auxiliary limiting ring 311, and an arc-shaped pressing plate 313 is fixedly installed on the bottom of the connecting bracket 312; a plurality of anti-slip washers 314 are fixedly installed on the inner wall of the auxiliary limiting ring 311, and when in use, when the connecting wire is passed through the wire groove and connected to the wiring seat 32 for limiting, the connecting wire synchronously passes through the inner cavity of the auxiliary limiting ring 311, and as the inclined limiting roller 34 approaches, a thrust is generated on the auxiliary limiting ring 311, so that the auxiliary The auxiliary limiting ring 311 is displaced synchronously, and then the arc pressure plate 313 is displaced in the inner cavity of the wire slot, and then the connecting wire is auxiliary limited inside the wire slot, so that the connecting wire is always kept in a limited and fixed state to avoid the problem of being accidentally pulled loose. Among them, the circumferential diameter length of the auxiliary limiting ring 311 is consistent with the inner circumferential diameter length of the wire slot opened at the bottom of the electric energy meter body 1, and the auxiliary limiting ring 311 is set in a mutually consistent state with the diameter of the wire slot opened at the bottom of the electric energy meter body 1 under normal conditions, and the arc pressure plate 313 is slidably installed in the inner cavity of the wire slot opened at the bottom of the electric energy meter body 1, and the connecting bracket 3 The auxiliary limiting ring 311 is installed at the bottom of the electric energy meter body 1 in a horizontal sliding state. The outer wall of the auxiliary limiting ring 311 is fixedly installed with a second telescopic spring 315 fixedly connected to the wire frame 31. The purpose of this arrangement is to make the connecting type pressing frame 33 tilt to press the insulating pressing plate 35 to press the connecting wire accordingly, while the limiting roller 34 simultaneously generates a thrust on the auxiliary limiting ring 311 to cause misalignment between it and the wire groove, thereby reducing the gap between the auxiliary limiting ring 311 and the wire groove, so that the connecting wire can be stably limited in the inner cavity of the wire groove in combination with the arc pressing plate 313, thereby avoiding the traditional connecting wire being connected to the terminal block 32. The bottom of the auxiliary limiting ring 311 is symmetrically arranged with respect to the vertical center line of the auxiliary limiting ring 311, so that the auxiliary limiting ring 311 can be more balanced in overall force, so that when pushed by the limiting roller 34, it can slide more stably and smoothly.

[0033] As a further extension of this solution, after the connecting wire and the terminal block 32 are fixed and limited, in order to prevent outdoor dust, impurities or flying insects from entering the wire frame 31 and the inside of the electric energy meter body 1 through the wire groove, refer to Figure 5 and Figure 7As shown, the blocking mechanism 4 includes a supporting plate 41 fixedly mounted on the bottom of the electric energy meter body 1, a connecting ring sleeve 42 is fixedly mounted on the bottom of the supporting plate 41, a hexagonal slide groove 43 is provided at the bottom of the connecting ring sleeve 42, a plurality of guide slide rods 44 are slidably mounted on the inner cavity of the hexagonal slide groove 43, and a plurality of guide slide rods 44 are fixedly mounted on the outer walls of the plurality of guide slide rods 44. Under normal conditions, the plurality of baffles 45 are spliced ​​together to enclose and block the connection between the supporting plate 41 and the wire groove. In actual use, the supporting plate 41 and the wire groove can be closed by splicing and enclosing the plurality of baffles 45 together. The connection between the wire trough and the supporting plate 41 is blocked. When the connecting wire passes through the supporting plate 41 and the wire trough, the multiple guide slide bars 44 are synchronously slid inside the hexagonal slide groove 43, so that the multiple baffles 45 are offset to expose gaps. The multiple baffles 45 can expose a certain gap according to the specifications of the connecting wire, and then the connection between the wire trough and the supporting plate 41 is blocked. At the same time, a rotating drum 46 is rotatably installed at the bottom of the connecting ring sleeve 42, and a plurality of limit grooves 47 slidably connected to the guide slide bars 44 are opened inside the rotating drum 46, so that in actual use, the rotating drum 46 can be rotated as a whole to The guide slide bar 44 slides in the inner cavity of the limit groove 47, and then the guide slide bar 44 is synchronously displaced inside the hexagonal slide groove 43 to drive the baffle plate 45 to deflect, and then a plurality of baffle plates 45 are exposed between the gaps for the connection line to pass through, wherein a gear ring 48 is fixedly installed on the outer wall of the rotating cylinder 46, and a locking type telescopic gear 49 is fixedly installed on the bottom of the supporting plate 41. The gear ring 48 and the locking type telescopic gear 49 are arranged in a mutually meshing state under normal conditions. Under normal conditions, the locking type telescopic gear 49 is in a contracted state and meshes with the gear ring 48. At this time, The gear ring 48 is limited by the fixed locking telescopic gear 49, so that it cannot rotate, and then the displacement of multiple baffles 45 cannot be adjusted. When the gap between the baffles 45 needs to be adjusted, the locking telescopic gear 49 is stretched to the longest state to move it away from the gear ring 48, so that the gear ring 48 loses its limit and can drive the rotating drum 46 to rotate and adjust it. After the adjustment is completed, the locking telescopic gear 49 is adjusted to the shortest state and meshed with the gear ring 48 to fix the adjusted positions of the multiple baffles 45, which is very convenient to use.

[0034] During the specific implementation, the connecting wire is first passed through the supporting plate 41 and the wire groove, and then through the auxiliary limiting ring 311, so that one end of the connecting wire contacts the terminal block 32, and then the threaded screw 39 is rotated to make the limiting pressure block 38 exert pressure on the limiting roller 34, and then the connecting pressure frame 33 is pushed as a whole to deflect toward the terminal block 32, so that the insulating pressure plate 35 is pressed on the connecting wire and the terminal block 32 and then stops rotating, completing the clamping and limiting work of the connecting wire. Synchronously, the limiting roller 34 pushes the auxiliary limiting ring 311 The force drives the arc pressure plate 313 to move in the inner cavity of the wire slot, and then the connecting wire is auxiliary limited inside the wire slot, completing the auxiliary limiting treatment of the exposed part of the connecting wire again, and finally, by rotating the drum 46, the multiple baffles 45 are driven to shift, so that the gaps between the multiple baffles 45 are just wrapped around the outer wall of the connecting wire, so that the locking telescopic gear 49 can be adjusted to the shortest state and meshed with the gear ring 48 to fix the adjusted positions of the multiple baffles 45, completing the blocking treatment of the bottom of the wire slot.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
