Technical Field

[0001] The utility model relates to the technical field of power distribution line switching, in particular to a power distribution line switching device. Background Art

[0002] Electricity is an energy source that uses electrical energy as a motive force. It was invented in the 1870s. The invention and application of electricity set off the second wave of industrialization and became one of the three scientific and technological revolutions that have taken place in the world since the 18th century in human history. Since then, technology has changed people's lives. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is an electricity production and consumption system composed of power generation, transmission, transformation, distribution and power consumption. It converts primary energy in nature into electricity through mechanical energy devices, and then supplies electricity to various users through transmission, transformation and distribution.

[0003] At present, an existing power distribution line switching device (such as patent number: 202020794695.6) discloses a power distribution line switching device, which belongs to the technical field of line switching devices, including a separate switching box, and switching ports are arranged on both sides of the upper end of the separate switching box, and wires are connected between the switching ports. The separate switching box is located on the surface of the wire and an insulating layer is arranged. The utility model provides a separate switching box, and a corresponding number of separate switching boxes are assembled according to usage requirements. The card block is inserted into the card slot of another group of separate switching boxes to realize the card connection between the separate switching boxes and the separate switching boxes. The fixing ball is pushed out and inserted into the fixing hole under the action of the reset spring to realize the limited fixation of the card block and the card slot to avoid separation and improve the fixing firmness.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the device assembles a corresponding number of separate adapter boxes according to usage requirements, and the card block is inserted into the card slot of another group of separate adapter boxes to achieve the snap connection between the separate adapter boxes. The fixed ball is pushed out and inserted into the fixed hole under the action of the reset spring, so as to achieve the limited fixation of the card block and the card slot to avoid separation and improve the fixing firmness. However, since most of the device is fixedly installed inside the electrical box, maintenance can only be carried out inside the electrical box when the line is tested in the later stage, which makes it inconvenient to operate it during maintenance and is relatively inconvenient to use. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies of the prior art, the utility model provides a power distribution line switching device to solve the technical problem that the power lines are all fixed in an internal position of an electric box and are inconvenient to maintain.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A power distribution line switching device comprises an electric line protection box, a limit slot is provided at the lower end of the electric line protection box, and linkage slide slots are provided on both the left and right sides of the electric line protection box; wherein a rotating side baffle is rotatably mounted on the front side end of the electric line protection box, and a fixed handle is fixedly mounted on the side end of the rotating side baffle; wherein a circuit line connection plate is slidably mounted inside the electric line protection box, and a switching end is fixedly mounted inside the circuit line connection plate.

[0010] Preferably: limiting rings are fixedly installed on both sides of the left and right sides of the circuit line connection plate; wherein, a shrink ring is fixedly installed on the side end of each limiting ring away from the side of the circuit line connection plate, and a limiting rod is fixedly installed on the lower end of the circuit line connection plate; wherein, a pulling handrail is rotatably installed on the lower end of the limiting rod.

[0011] Preferably: the limit rod part is installed at the position below the electric circuit protection box through the limit groove opened at the bottom of the electric circuit protection box; wherein each of the limit ring and shrink ring part is installed on the left and right sides of the electric circuit protection box through the linkage slide groove opened on the left and right sides of the electric circuit protection box, and each of the shrink rings is threadedly installed with a trapezoidal fixed clamp on the outer surface; wherein the outer surfaces of each of the adapter ends on the same horizontal line are connected through the adapter wire part, and connecting wires are fixedly installed on the left and right sides of each of the adapter wires; wherein each of the adapter ends is connected to the connecting wire part, and thus connected to each other through the adapter wire part.

[0012] (III) Beneficial effects

[0013] 1. The user first pulls the fixed handle, which drives the rotating side baffle to rotate, and then pulls the pulling handrail. Pulling the handrail drives the limit rod to drive the circuit line connection plate to slide inside the electric circuit protection box, slide it to the front end of the electric circuit protection box, and expose the inside of the electric circuit protection box by rotating the rotating side baffle. Then, pull the pulling handrail to drive the circuit line connection plate to slide forward, thereby exposing the line to the periphery of the device, so as to achieve the beneficial effect of facilitating maintenance after the later installation is completed.

[0014] Second, because the trapezoidal fixed clamp has a larger opening on one side and a smaller opening on the other side, when the trapezoidal fixed clamp rotates on the outer surface of the shrink ring, the shrink ring part will gradually shrink, and then the circuit line will be clamped and fixed. The shrink ring part is driven to gradually shrink by the rotation of the trapezoidal fixed clamp, so that the shrink ring part squeezes the circuit line, thereby achieving the beneficial effect of fixing the circuit line and preventing the circuit line from detaching.

Pulling the handrail drives the limit rod to drive the circuit line connection plate part to slide inside the electric line protection box, slide it to the front end of the electric line protection box, and expose the inside of the electric line protection box by rotating the rotating side baffle. Then, pull the pulling handrail to drive the circuit line connection plate part to slide forward, thereby exposing the line to the periphery of the device, so as to achieve the beneficial effect of facilitating maintenance after the later installation is completed. Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the electric circuits are fixed in the internal position of the electric box and are inconvenient to maintain. The overall idea is as follows: an electric power distribution line switching device, including an electric circuit protection box 1, a limit groove 11 is provided at the lower end of the electric circuit protection box 1, and linkage slide grooves 12 are provided on the left and right sides of the electric circuit protection box 1; wherein, a rotating side baffle 13 is rotatably installed at the front side end of the electric circuit protection box 1, and a fixed handle 14 is fixedly installed at the side end of the rotating side baffle 13; wherein, a circuit line connecting plate 15 is slidably installed inside the electric circuit protection box 1, and a switching end 16 is fixedly installed inside the circuit line connecting plate 15, and the rotating side baffle 13 is driven to rotate around the part of the electric circuit protection box 1 along the side end protrusion by pulling the fixed handle 14, so as to achieve the effect of protecting the internal circuit.

[0023] In view of the problems existing in the prior art, the utility model provides a power distribution line switching device, wherein limit rings 17 are fixedly installed on both sides of a circuit line connection plate 15; wherein a shrink ring 18 is fixedly installed on the side end of each limit ring 17 away from the circuit line connection plate 15, and a limit rod 19 is fixedly installed on the lower end of the circuit line connection plate 15; wherein a pulling handrail 2 is rotatably installed on the lower end of the limit rod 19, and the limit rings 17 and shrink rings 18 installed on both sides of the circuit line connection plate 15 cooperate with the trapezoidal fixed clamp 21 to achieve the effect of quickly fixing the installed circuit line.

[0024] The limit rod 19 part is installed at the lower position of the electric circuit protection box 1 through the limit groove 11 opened at the lower part of the electric circuit protection box 1; wherein, each limit ring 17 and shrink ring 18 part is installed on the left and right sides of the electric circuit protection box 1 through the linkage slide groove 12 opened on the left and right sides of the electric circuit protection box 1, and the outer surface of each shrink ring 18 is threadedly installed with a trapezoidal fixed clamp 21; wherein, the outer surface of each adapter end 16 on the same horizontal line is connected through the adapter line 22 part, and by pulling the handrail 2, the limit rod 19 part is driven to slide along the limit groove 11, thereby driving the circuit line connection plate 15 part to slide inside the electric circuit protection box 1.

[0025] Connecting wires 23 are fixedly installed on the left and right sides of each adapter wire 22; wherein, each adapter terminal 16 is connected to a portion of the connecting wire 23, so as to be connected to each other through the adapter wire 22 portion, and the connecting wires 23 on both sides of the adapter wire 22 cooperate with the bolts and the adapter terminal 16 to achieve the effect of connecting the circuit lines on both sides.

[0026] Working principle:

[0027] The first step is that when the user is in use, the device is placed on a horizontal surface, the user picks up the electric circuit protection box 1, installs the rotating side baffle 13 on the front side of the electric circuit protection box 1, and then installs the fixed handle 14 on the side end of the rotating side baffle 13. Then the user picks up the circuit line connection plate 15, installs the upper limit rings 17 on the left and right sides of the circuit line connection plate 15, and then installs the adapter end 16 inside the circuit line connection plate 15, and then installs the shrink ring 18 on the side end of each limit ring 17, and finally installs the upper limit rod 19 part under the circuit line connection plate 15, slides the assembled circuit line connection plate 15 part into the electric circuit protection box 1, and puts the limit ring 17 and the shrink ring 18 on the side end of each limit ring 17. 8 parts are installed along the linkage slide grooves 12 opened on both sides of the electric circuit protection box 1, and the limit rod 19 parts are installed along the limit grooves 11 opened at the bottom of the electric circuit protection box 1. Then the user picks up the pull handrail 2 and connects the pull handrail 2 with the limit rod 19 part from the bottom of the electric circuit protection box 1. Then the user installs the trapezoidal fixed clamp 21 on the outer surface of each shrink ring 18. Then the user picks up the adapter wire 22 and installs the connecting wires 23 on both sides of the left and right sides of the adapter wire 22. Then the assembled adapter wire 22 parts are connected to the adapter terminals 16 on a horizontal line along the connecting wires 23, and the connecting wires 23 are installed on the outer surface of the adapter terminal 16.

[0028] In the second step, when the user needs to use the device, the user sets the trapezoidal fixed clamp 21 on the outer surface of the circuit line that needs to be connected, and then passes one side of the circuit line through the internal hole of the limit ring 17 to connect with the adapter end 16 inside the circuit line connection plate 15, and then slides the trapezoidal fixed clamp 21 to install it on the outer surface of the shrink ring 18. Because the trapezoidal fixed clamp 21 has a large opening on one side and a small opening on the other side, when the trapezoidal fixed clamp 21 rotates on the outer surface of the shrink ring 18, it will gradually shrink the shrink ring 18, and then clamp and fix the circuit line, and then the user uses the adapter line 2 2 parts slide the connecting wires 23 on both sides of the adapter line 22 to the outer surface of the adapter end 16 to clamp the circuit line between the adapter end 16 and the connecting wires 23, and then turn the upper bolt to fix it. At this time, the installation and connection of the circuit line can be completed. When the circuit line needs to be inspected and repaired later, the user first pulls the fixed handle 14, and the fixed handle 14 drives the rotating side baffle 13 to rotate, and then pulls the handrail 2 part. Pulling the handrail 2 drives the limit rod 19 to drive the circuit line connecting plate 15 part to slide inside the electric circuit protection box 1, and slide it to the front side end of the electric circuit protection box 1 for easy inspection and maintenance.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
