[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] Example 1

[0040] See also Figure 1-6 The present invention provides a novel multifunctional electric meter, comprising a multifunctional electric meter body 1, a display panel 22 is fixedly connected to the front end of the multifunctional electric meter body 1, and a switch inspection port 23 fixedly connected to the front end of the multifunctional electric meter body 1 is arranged below the display panel 22, a plurality of wires 11 are electrically connected to the bottom end of the multifunctional electric meter body 1, and the wires 11 at least include a power line, a voltage line, a current line and a neutral line, the other end of the wire 11 passes through the interior of a protective component 12, and passes through the interior of a back plate 9 and a mounting plate 10, the protective component 12 comprises a flexible sleeve 1201, a filling layer 1202, a through hole 1203, and a connecting sleeve 1 204 and flexible steel wire 1205, the outer side wall of the wire 11 is tightly fitted with the outer side wall of the filling layer 1202 filled with flame retardant particles, and the outer side wall of the filling layer 1202 away from the wire 11 is fixedly connected to the inner side wall of the flexible sleeve 1201, the flexible sleeve 1201 is close to the outer side wall connecting seat of the front end outer wall of the mounting plate 10, and the connecting seat is fixedly connected to the front end of the mounting plate 10 at equal intervals, the tube body of the flexible sleeve 1201 is penetrated by through holes 1203 at equal intervals, and the inside of the through holes 1203 is fixedly connected with connecting sleeves 1204, and the inside of the connecting sleeves 1204 is fixedly connected with flexible steel wires 1205.

[0041] The basic power parameter data measured by the multi-function electric meter body 1 is displayed through the display panel 22, and the switch inspection port 23 can be opened to open or close the main pipe switch. During use, the protective component 12 is used to protect the wire 11, and the filling layer 1202 is tightly attached to the outer surface of the wire 11. When a short circuit and open flame occur in the wire 11, the flame retardant particles filled in the filling layer 1202 are effectively used to perform flame retardant operations on the short circuit and open flame area of ​​the wire 11, which effectively avoids the damage of the remaining wires 11 by the open flame due to the short circuit, and further spreads the harm. At the same time, the flexible steel wires 1205 are evenly spaced through the inside of the flexible sleeve 1201, so that the connecting sleeve 1204 has a certain toughness. In this way, when the multi-function electric meter body 1 is installed, the wire 11 has a certain toughness, and the protective effect of the wire 11 during installation and use is further improved.

[0043] By setting the plug-in block 4, after the movable sleeve 8 corresponds to the plug-in cavity 3, the plug-in block 4 is inserted into the movable sleeve 8 to be plugged into the inside of the plug-in cavity 3 until the two plug-in blocks 4 are plugged into the limit position, so that one end of the connecting block 7 fits with one end of the magnetic block 6 and is magnetically attracted, so that the multifunctional meter body 1 is installed to the front end of the plug-in cavity 3. In this way, the multifunctional meter body 1 can be quickly disassembled and assembled, avoiding the problem of difficult operation during the later repair or maintenance of the multifunctional meter body 1 due to the small installation area of ​​the multifunctional meter body 1.

[0044] Several groups of combing components 13 are fixedly connected at equal intervals inside the flexible sleeve 1201, and each group of combing components 13 is fixedly connected to the inner wall of the flexible sleeve 1201 at equal intervals. Each group of combing components 13 is fixedly connected to the filling layer 1202 inside the flexible sleeve 1201. The combing components 13 include a mounting seat 1301, a movable cavity 1302 and a rolling ball 1303. Several rolling balls 1303 are in contact with the outer wall of the wire 11, and the rolling balls 1303 are movably connected to the inside of the movable cavity 1302. One end of the movable cavity 1302 is fixedly connected to the inner wall of the flexible sleeve 1201 through the mounting seat 1301.

[0045] By setting up the combing component 13, when the wire 11 passes through the flexible sleeve 1201 to comb the wire 11, the wire 11 collides with the ball 1303, and the ball 1303 moves inside the movable cavity 1302, so as to transmit the wire 11, making it easier to operate the wire 11 when passing through the flexible sleeve 1201.

[0046] The bottom end of the multifunctional electric meter body 1 is connected to the bottom end of the wire 11, which conflicts with the top end of the insulating cushion material 14, and the bottom end of the insulating cushion material 14 conflicts with the inner top end of the conflicting frame 15. The conflicting frame 15 is a "concave" structure. The top end of the insulating cushion material 14 and the inner top end of the conflicting frame 15 are respectively penetrated with corresponding adapter holes and series holes. The inner side walls of the series holes are fixedly connected with a balloon block 16 with a circular ring structure, and the balloon block 16 is an inflatable structure. The outer side wall of the balloon block 16 away from the inner side wall of the series hole is tightly fitted with an insulating ring 17, and the insulating ring 17 is away from the balloon block 1 The outer wall of 6 conflicts with the outer wall of the wire 11, and the outer walls of both ends of the conflict frame 15 are evenly fixedly connected with the first conflict block 18 of the semi-cylindrical structure.

[0047] By setting the insulating pad 14, the insulating pad 14 can insulate and protect the bottom connection part of the wire 11 and the multi-function meter body 1 during use to avoid leakage and other phenomena. At the same time, the set resistance frame 15 resists the bottom end of the insulating pad 14, and then limits the insulating pad 14. When the wire 11 passes through the serial hole of the resistance frame 15, the balloon block 16 set on the inner wall of the serial hole drives the insulating ring 17 to wrap around the outer wall of the wire 11 due to the characteristics of the balloon block 16, and then further limits the wire 11, thereby effectively avoiding the phenomenon of the wire 11 falling off during the use of the multi-function meter body 1.

[0048] The specific use process of this embodiment is as follows:

[0049] First, the insertion cavity 3 is fixed by means of bolts and other mounting components, thereby completing the installation and positioning of the back plate 9 and the mounting plate 10;

[0050] Secondly, by setting the plug-in block 4, after the movable sleeve 8 corresponds to the plug-in cavity 3, the plug-in block 4 is inserted into the plug-in cavity 3 through the movable sleeve 8 until the two plug-in blocks 4 are plugged into the limit position, so that one end of the connecting block 7 fits with one end of the magnetic block 6 and is magnetically attracted, so that the multifunctional electric meter body 1 is installed at the front end of the plug-in cavity 3;

[0051] Afterwards, when the wire 11 passes through the flexible sleeve 1201 to comb the wire 11, the wire 11 is in conflict with the rolling ball 1303, and then the rolling ball 1303 moves inside the movable cavity 1302, and the filling layer 1202 is arranged to closely fit the outer surface of the wire 11, and then when the wire 11 has a short circuit open flame, the flame retardant particles filled in the filling layer 1202 will effectively perform a flame retardant operation on the short circuit open flame area of ​​the wire 11;

[0052] Then, the insulating pad 14 is used to insulate and protect the bottom connection part between the wire 11 and the multi-function meter body 1 to avoid leakage and other phenomena. At the same time, the abutment frame 15 is set to abut against the bottom end of the insulating pad 14, thereby limiting the position of the insulating pad 14. When the wire 11 passes through the series hole of the abutment frame 15, the balloon block 16 set on the inner side wall of the series hole drives the insulating ring 17 to wrap around the outer side wall of the wire 11 due to the characteristics of the balloon block 16, thereby further limiting the position of the wire 11.

[0053] Finally, the basic power parameter data measured by the multifunctional electric meter body 1 is displayed through the display panel 22, and the main switch can be opened or closed by opening the switch inspection port 23, and the new multifunctional electric meter is used.
