[0021] The embodiment of the present application provides an intelligent measuring switch with a remote tripping function, which effectively solves the technical problem that when the measuring switch trips, the staff needs to perform maintenance. If the staff accidentally touches the handle 2 and causes the handle 2 to rotate upward during maintenance, it will affect the staff's normal maintenance work.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application effectively solves the technical problem that when the measuring switch is tripped, the staff needs to perform maintenance. If the staff touches the handle 2 by mistake and turns the handle 2 upward during maintenance, it will affect the normal maintenance work of the staff. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides an intelligent measuring switch with a remote tripping function, the intelligent measuring switch with a remote tripping function comprises a housing 1, the outside of the housing 1 is rotatably connected with a handle 2, the lower end of the housing 1 is provided with a communication port 3, the outside of the housing 1 is provided with a limiting mechanism, the limiting mechanism comprises a mounting shaft 4, a limiting plate 5, a slot 6, a slide groove 7, a plug plate 8 and a spring 9, the mounting shaft 4 is arranged at one end of the housing 1 close to the handle 2, the limiting plate 5 is rotatably connected to the outside of the mounting shaft 4, there are two slots 6, both of which are arranged on the outside of the limiting plate 5, the slide groove 7 is arranged on a side of the mounting shaft 4 close to the slot 6, and the plug plate 8 is slidably connected between the slide groove 7 and the plug plate 8. Inside the slot 6, one end of the spring 9 is fixedly connected to the outside of the plug plate 8, and the other end of the spring 9 is fixedly connected to the inside of the slide slot 7. By setting the limit plate 5 and cooperating with the plug plate 8, when the intelligent measuring switch trips, the staff needs to perform maintenance. At this time, the plug plate 8 is moved to release the connection between the plug plate 8 and the slot 6. At this time, the spring 9 is compressed. At this time, the limit plate 5 is rotated so that the limit plate 5 is located above the handle 2. At this time, the plug plate 8 is released, and the plug plate 8 enters the inside of the slot 6 under the action of the spring 9. At this time, the limit plate 5 is fixed. At this time, the limit plate 5 is located above the handle 2, and the handle 2 cannot be rotated upward, which prevents the staff from accidentally touching the handle 2 during maintenance, causing the handle 2 to rotate upward and affecting the normal maintenance work of the staff.

[0025] A support shaft 10 is fixedly installed inside the slide groove 7, and the spring 9 is movably sleeved on the outside of the support shaft 10 to limit the movable path of the spring 9. A threaded rod 12 is fixedly installed outside the shell 1, and each threaded rod 12 is threadedly connected with a threaded cap 13. The installation shaft 4 is slidably connected to the outside of the two threaded rods 12 away from the two ends of the slide groove 7, which is convenient for the disassembly and assembly of the installation shaft 4.

[0026] A connecting rope 14 is fixedly installed on the outside of the plug board 8, and a pull ring 15 is fixed on the outside of the connecting rope 14, which is convenient for pulling the plug board 8. An opening 16 is opened at one end of the installation shaft 4 close to the slide slot 7, and the opening 16 is communicated with the inside of the slide slot 7. The connecting rope 14 is slidably connected to the inside of the opening 16, and the pull ring 15 is located on the outside of the slide slot 7 to limit the path of the connecting rope 14. By setting the connecting rope 14 and cooperating with the pull ring 15, when the plug board 8 is moved, the pull ring 15 is held to drive the connecting rope 14 so that the connecting rope 14 drives the plug board 8 to move. At this time, the spring 9 is compressed. When the limit plate 5 has completed its rotation, the pull ring 15 is released. At this time, the plug board 8 is reset under the action of the spring 9. At the same time, the plug board 8 drives the connecting rope 14 and the pull ring 15 to reset, which is convenient for the staff to pull the plug board 8 to quickly rotate the limit plate 5.

[0027] Two baffles 11 are fixedly mounted on the outside of the installation shaft 4 . The two baffles 11 are located at both ends of the slide groove 7 to prevent the connection between the limit plate 5 and the installation shaft 4 from being released.

[0028] Working principle:

[0029] The first step is to set the limit plate 5 and cooperate with the plug plate 8. When the intelligent measuring switch trips, the staff needs to perform maintenance. At this time, the pull ring 15 is held to drive the connecting rope 14 so that the connecting rope 14 drives the plug plate 8 to move so that the connection between the plug plate 8 and the slot 6 is released. At this time, the spring 9 is compressed. At this time, the staff rotates the limit plate 5 downward and releases the pull ring 15. At this time, the plug plate 8 is reset under the action of the spring 9. At the same time, the plug plate 8 drives the connecting rope 14 and the pull ring 15 to reset. At this time, the plug plate 8 enters the inside of another slot 6. At this time, the limit plate 5 is fixed. At this time, the limit plate 5 is located above the handle 2. At this time, the handle 2 cannot be rotated upward, so as to avoid the staff from accidentally touching the handle 2 during maintenance, causing the handle 2 to rotate upward and affecting the normal maintenance work of the staff;

[0030] In the second step, when the maintenance is completed, hold the pull ring 15 to drive the connecting rope 14 so that the connecting rope 14 drives the plug plate 8 to move. At this time, the spring 9 is compressed, and the connection between the plug plate 8 and the slot 6 is released. At this time, the limit plate 5 is rotated to reset the limit plate 5. At this time, release the pull ring 15. At this time, the plug plate 8 is reset under the action of the spring 9. At this time, the limit plate 5 is fixed to avoid affecting the movement of the handle 2.

[0031] 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.
