[0031] Reference Figure 1-Figure 7 , an elevator shaft wire branch connection structure, including a connection base 1, a main line 1 4 and a main line 2 5 connected end to end are respectively inserted at both ends of the connection base 1, a branch line 6 inserted in the connection base 1 is arranged above the main line 2 5 on the same side, the main line 1 4 includes a first incoming line 41, a second incoming line 42 and a third incoming line 43, the main line 2 5 includes a first outgoing line 51, a second outgoing line 52 and a third outgoing line 53, and the branch line 6 includes a first branch line 61, a second branch line 62 and a third branch line 63, refer to Figure 1 As shown, originally the first input line 41 and the first output line 51, the second input line 42 and the second output line 52, and the third input line 43 and the third output line 53 are connected to form three connected circuits. This state is the initial state. At this time, the following operations need to be completed:

[0032] The first branch connection requirements:

[0033] It is necessary to switch all or part of the first outgoing line 51, the second outgoing line 52 and the third outgoing line 53 in the main line 2 5 to the corresponding first branch line 61, the second branch line 62 and the third branch line 63, that is, to complete the first incoming line 41 to match the first outgoing line 51 or the first branch line 61, the second incoming line 42 to match the second outgoing line 52 or the second branch line 62, and the third incoming line 43 to match the third outgoing line 53 or the third branch line 63;

[0034] To complete this switching method, you need to complete the following steps:

[0035] Reference Figure 2 State, wherein the main line 2 5 and the branch line 6 are connected to the connecting base 1 through the first protruding block 9 and the second protruding block 11 respectively, and a swinging metal rod 7 for switching the connection point of the main line 1 4 from the main line 2 5 to the branch line 6 is provided in the connecting base 1, the main line 1 4 is connected to the main line 2 5 or the branch line 6 through the swinging metal rod 7 rotating at the end, one end of the swinging metal rod 7 is connected to the main line 1 4 for rotation, and the first protruding block 9 and the second protruding block 11 have a first slot 10 and a second slot 12 for positioning the swinging metal rod 7 at the opposite ends respectively, so that the swinging metal rod 7 originally placed on the first slot 10 in the first protruding block 9 is switched to the second slot 12 in the second protruding block 11 through the rotation of the swinging metal rod 7, thereby completing the switching of the current flow.

[0036] It should be noted that an insulating tape 8 is wound around the swinging metal rod 7, an operating table 2 is provided on the connecting base 1, and a plurality of operating columns 3 are inserted in the operating table 2. The operating columns 3 drive the insulating tape 8 to reel up by pressing, so that the free end position of the swinging metal rod 7 changes. Figure 2 and Figure 4 Show.

[0037] A pressing ring 24 is provided at the bottom of the operating table 2 coaxially with the operating column 3, and the pressing ring 24 is reset and raised by a reset spring 25. First, the operating column 3 corresponding to the first outlet line 51, the second outlet line 52 and the third outlet line 53 to be switched is selected, and then the corresponding operating column 3 is pressed to make the operating column 3 descend, and the pressing ring 24 is driven to descend together;

[0038] Since the pressing ring 24 is provided with a first rack 26 inserted into the operating table 2, a first sliding cavity 23 for providing lifting and lowering for the first rack 26 is opened in the operating table 2, and a first gear 27 meshing with the first rack 26 is also provided in the first sliding cavity 23, wherein the first gear 27 is coaxially fixed with the winding rod 28. Therefore, the pressed pressing ring 24 will descend with the first rack 26, and then rotate with the first gear 27 and the winding rod 28, and finally form a winding effect on the insulating tape 8 wound on the winding rod 28. After the winding is completed, the vertical position of the operating column 3 is limited by using an external buckle, so that the operating column 3 can only complete the rotation without moving up and down.

[0039] The operating table 2 is also provided with a winding rod 28 for winding up the insulating tape 8. One end of the insulating tape 8 is fixed to the bottom of the operating table 2, and the other end is wound around the winding rod 28. In this way, the winding rod 28 can be rotated to allow the winding rod 28 to wind around the insulating tape 8, thereby shortening the length of the insulating tape 8, and finally lifting the swinging metal rod 7 and allowing it to enter the second slot 12 and abut against the second protruding block 11, thereby finally completing the electrical connection switching effect of the first input line 41 being matched with the first output line 51 or the first branch line 61, the second input line 42 being matched with the second output line 52 or the second branch line 62, and the third input line 43 being matched with the third output line 53 or the third branch line 63.

[0040] The second branch connection requirement:

[0041] The electrical connection is switched based on the first branch connection. First, the first incoming line 41, the second incoming line 42 and the third incoming line 43 are connected to the first branch line 61, the second branch line 62 and the third branch line 63 in a one-to-one correspondence, and then the connection point is changed, that is, the first incoming line 41 can be connected to at most three of the first branch line 61, the second branch line 62 and the third branch line 63 at the same time or selectively, or electrically connected in a non-corresponding connection manner;

[0042] To complete this switching method, you need to complete the following steps:

[0043] Reference Figure 5 In this state, the second protruding block 11 is respectively provided with a first gap cavity 13, a second gap cavity 14 and a third gap cavity 15 equidistant from each other, and an insulating column 39 is coaxially arranged inside, so as to ensure that no current will flow between the first gap cavity 13, the second gap cavity 14 and the third gap cavity 15 if there is no conductive medium.

[0044] A first lifting metal block 30 , a second lifting metal block 31 and a third lifting metal block 32 for connecting current are respectively inserted between the first gap cavity 13 , the second gap cavity 14 and the third gap cavity 15 , so as to ensure the required switching current.

[0045] A first trigger box 16, a second trigger box 17 and a third trigger box 18 are respectively provided above the multiple second protruding blocks 11, and a conductive block 33 is provided on the top of the first lifting metal block 30, the second lifting metal block 31 and the third lifting metal block 32, and the conductive block 33 slides vertically through the second sliding cavity 29, so that the on / off and steering of the circuit can be adjusted by controlling the lifting and lowering of the first lifting metal block 30, the second lifting metal block 31 and the third lifting metal block 32.

[0046] The first trigger box 16 , the second trigger box 17 and the third trigger box 18 are respectively provided with a first metal plate 19 , a second metal plate 20 and a third metal plate 21 correspondingly connected to the first branch line 61 , the second branch line 62 and the third branch line 63 .

[0047] Reference Figure 3 It can be seen that the first trigger box 16 is provided with three contacts, namely, a1, a2 and a3. At this time, the magnet 34 at the top of the a1 contact in the initial state will attract and drive the first lifting metal block 30 to lift, and the first lifting metal block 30 in the first trigger box 16 is longer than the second lifting metal block 31 and the third lifting metal block 32 in the first trigger box 16. Therefore, when the first lifting metal block 30 is lifted to the top, the first lifting metal block 30 is still in the first gap cavity 13. At this time, the first lifting metal block 30 is lifted to the top. The second protruding block 11 below the trigger box 16 is in a fully connected state, and the current can flow directly from the second protruding block 11 to the first branch line 61. At this time, the highest points of the second lifting metal block 31 and the third lifting metal block 32 corresponding to a2 and a3 are respectively connected to the second metal plate 20 and the third metal plate 21 through wires, so that it can be ensured that when the second lifting metal block 31 is lifted to the highest point, the originally unconnected point a2 and the conductive rod 38 will be connected because the second lifting metal block 31 carries the conductive block 33;

[0048] It should be noted that the conductive block 33 slides with the side wall of the second sliding cavity 29, that is, it will contact the conductive rod 38 during the sliding process, while the first lifting metal block 30, the second lifting metal block 31 and the third lifting metal block 32 are not connected to the side wall of the second sliding cavity 29. Therefore, during the lifting process of the second lifting metal block 31 and the third lifting metal block 32, the second lifting metal block 31 and the third lifting metal block 32 will not contact the conductive rod 38.

[0049] A plurality of conductive rods 38 are disposed in the second sliding cavity 29. The distribution of the conductive rods 38 in the first trigger box 16 is shown in FIG. Figure 6 As shown, at this time, the first lifting metal block 30 and the conductive block 33 on the top of the lifted second lifting metal block 31, and the second lifting metal block 31 is not located in the second gap cavity 14, allowing the current to pass through the first lifting metal block 30, and pass through the conductive rod 38 to reach the conductive block 33 on the top of the second lifting metal block 31, and then the current flows from the wire at point a2 to the second metal plate 20, wherein the second metal plate 20 is connected to the second branch line 62, which ensures that the current originally flowing in from the first input line 41 will flow out from the second branch line 62.

[0050] When it is necessary to adjust the current to flow out from a3, it is only necessary to move the position of the magnet 34 and let the magnet 34 slide above the third lifting metal block 32. The third lifting metal block 32 is lifted under the suction force, and the second lifting metal block 31 will fall without the suction force. At this time, the first gap cavity 13 and the second gap cavity 14 are connected by the first lifting metal block 30 and the second lifting metal block 31. Similarly, the current will flow from the conductive rod 38 between the second lifting metal block 31 and the third lifting metal block 32 to point a3, and finally reach the third branch line 63 connected to the third metal plate 21, thereby achieving the effect that the current originally flowing in from the first input line 41 will flow out from the third branch line 63.

[0051] It should be noted that the first trigger box 16 and the third trigger box 18 have similar internal structures and the same principles. Figure 7 In the initial state, the magnet 34 will attract the second lifting metal block 31 to lift, and the second lifting metal block 31 in the second trigger box 17 is always located in the second gap cavity 14, ensuring that the second protruding block 11 in this state is in a connected state, that is, at this time, the current of the second input line 42 flows out from the second branch line 62. When the current flow direction needs to be adjusted, only the position of the sliding magnet 34 is sufficient, such as Figure 7 As shown, when the magnet 34 slides to the left to attract the first lifting metal block 30 to lift, since the first lifting metal block 30 and the third lifting metal block 32 in the second trigger box 17 have notch grooves 40 at the same end, the current will flow out from point b1 of the first lifting metal block 30 at this time. Conversely, when the magnet 34 slides to the right, the current will flow out from point b3.

[0052] Further, see Figure 3 , a2 and a3 of the first trigger box 16 are connected to the second metal plate 20 and the third metal plate 21 respectively through wires, b1 and b3 in the second trigger box 17 are connected to the first metal plate 19 and the third metal plate 21 respectively through wires, and c2 and c3 of the third trigger box 18 are connected to the second metal plate 20 and the first metal plate 19 respectively through wires. It can be obtained that the magnets 34 on the first trigger box 16 and the third trigger box 18 can complete the switching of the current lead-out from near to far by sliding twice in the same direction, and the magnet 34 of the second trigger box 17 can complete the switching of the current flow direction of the first branch line 61 and the third branch line 63 on both sides of the second branch line 62 by sliding left and right.

[0053] Among them, the operating column 3 switches the electrical connection between the branch lines 6 through the switching part, and the switching part includes a rotating rod 22 coaxially fixed with the operating column 3. Magnets 34 are slid on the first trigger box 16, the second trigger box 17 and the third trigger box 18. A second rack 36 sliding along the axis of the second protruding block 11 is provided above the magnet 34, and a second gear 37 meshing with the second rack 36 is fixed at the bottom of the rotating rod 22. The magnet 34 is connected to the second rack 36 through a connecting rod 35. Therefore, when adjusting the current flow direction, it is only necessary to rotate the second gear 37 to drive the magnet 34 under the second rack 36 to slide.

[0054] To switch the current on the first branch line 61 to the second branch line 62, it is only necessary to rotate the operating column 3 once and displace the magnet 34 once. If the current on the first branch line 61 is switched to the third branch line 63, it is necessary to rotate the operating column 3 twice and displace the magnet 34 twice. The same is true for the current flow direction of the third branch line 63. However, for the flow direction of the current on the second branch line 62, it is necessary to reverse the operating column 3 to complete the current flow of the first branch line 61 and the third branch line 63. Therefore, the first input line 41 can be marked with the first output line 51 or the first branch line 61, the second input line 42 can be marked with the second output line 52 or the second branch line 62, and the third input line 43 can be marked with the third output line 53 or the third branch line 63. Electrical connection switching effect;

[0055] Then, by rotating the operating column 3, the current transfer between the first branch line 61, the second branch line 62 and the third branch line 63 is completed, and finally the branch connection of the current flow direction is quickly switched.

[0056] The working principle of the present invention is as follows:

[0057] Changing the current flow direction between the main line 1 4 and the main line 2 5: that is, the operating column 3 drives the insulating tape 8 to reel up by pressing, so that the free end position of the swinging metal rod 7 changes, that is, the first gear 27 is coaxially fixed with the winding rod 28, so the downward pressing ring 24 will bring the first rack 26 down together, and then drive the first gear 27 and the winding rod 28 to rotate, and finally form a reeling effect on the insulating tape 8 wound on the winding rod 28, and the winding rod 28 winds the insulating tape 8, thereby shortening the length of the insulating tape 8, and finally achieving the effect of lifting and lifting the swinging metal rod 7 and entering the second slot 12 to abut against the second protruding block 11, and finally completing the effect of switching the electrical connection between the first input line 41 and the first output line 51 or the first branch line 61, the second input line 42 and the second output line 52 or the second branch line 62, and the third input line 43 and the third output line 53 or the third branch line 63;

[0058] Changing the current flow direction between the first branch line 61, the second branch line 62 and the third branch line 63: To switch the current on the first branch line 61 to the second branch line 62, it is only necessary to rotate the operating column 3 once and shift the magnet 34 once to complete it. If the current on the first branch line 61 is switched to the third branch line 63, it is necessary to rotate the operating column 3 twice and shift the magnet 34 twice, and the current flow direction operation of the third branch line 63 is the same. However, for the current flow direction of the second branch line 62, it is necessary to reverse the operating column 3 to complete the current flow of the first branch line 61 and the third branch line 63. Therefore, the first input line 41 can be marked with the first output line 51 or the first branch line 61, the second input line 42 can be marked with the second output line 52 or the second branch line 62, and the third input line 43 can be marked with the third output line 53 or the third branch line 63. Electrical connection switching effect;

[0059] Then, by rotating the operating column 3, the current transfer between the first branch line 61, the second branch line 62 and the third branch line 63 is completed, and finally the branch connection of the current flow direction is quickly switched.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
