The working principle is as follows: the invention belongs to a charge-discharge controller of a solar storage battery, a worker manually holds a lead wire 18 to control a plurality of inner metal wires 19 to be inserted into a wiring board block 2 and to be inserted between a top block 20 and a deformation plate 4, before the process, the outer plate 24 needs to be manually pulled, the outer plate 24 drives a brake column 23, the brake column 23 drives the top block 20, the top block 20 overcomes the elastic pushing influence of a second spring 21 in the moving process, the top block 20 moves to drive an air column 26, the air column 26 is relatively inserted into a sleeve 25 and can be influenced by the air pressure between a control valve 27 and the air column 26, the gas in the sleeve 25 cannot pass through the control valve 27 originally, because the guide pipe 29 is driven in the moving process of the outer plate 24, the guide pipe 29 can be drawn out from a hard pipe 28, so that the gas is supplemented into the hard pipe 28 and is realized through the internal control of the guide pipe 29, but the internal control aperture of the guide pipe 29 is small, the air supplement in the hard tube 28 cannot be realized quickly in a short time, so that a negative pressure environment occurs in the hard tube 28, the air pressure acts on the pressure column 30, the pressure column 30 retracts into the hard tube 28, the pressure column 30 moves to drive the sealing ball 32, the pushing influence of the third spring 31 is overcome in the process, the sealing ball 32 moves away from the sealing barrel 33, so that the air column 26 falls into the sleeve 25 to pass through, the gas in the sleeve 25 can timely pass through a channel between the sealing ball 32 and the sealing barrel 33 to be discharged outwards without being inhibited by the air pressure in the sleeve 25, after the inner metal wire 19 extends to a middle position of the wiring board block 2, the jacking body assembly 5 is not controlled any more, the second spring 21 elastically pushes the jacking body block 20, the jacking body block 20 pushes against the inner metal wire 19 to force the inner metal wire 19 to be in an arc-shaped bending state, finally the inner metal wire 19 is clamped between the jacking body block 20 and the deformation board 4, and if an accidental pulling action occurs on the lead 18, the wire 18 pulls the inner metal wire 19 outwards, after the inner metal wire 19 is clamped, the pulling force firstly changes the inner metal wire 19 into a stretched straight state, and in the process, the top body block 20 moves reversely, the reverse movement of the top body block 20 can cause the air column 26 to sink into the sleeve 25, so that the air pressure in the sleeve 25 inhibits the movement of the air column 26, and further inhibits the movement of the top body block 20, thereby the process of the stretched straight state of the inner metal wire 19 is inhibited, further the inner metal wire 19 is prevented from being directly pulled out of the wiring board block 2, the stable connection between the inner metal wire 19 and the wiring board block 2 is ensured, if the inner metal wire 19 is accidentally pulled to force the inner metal wire 19 to be pulled into the wiring board block 2, specifically, the contact between the inner metal wire 19 and the deformation board 4 is changed into a dangerous state, namely, the contact surface is too small to meet the smooth flowing of the current, and the circuit breaking operation is required at this time, because the inner metal wire 19 is padded between the deformation plate 4 and the top body block 20, once the inner metal wire 19 is pulled to the outside of the wiring board block 2 by half, the inner metal wire 19 of the interception transverse column 15 disappears and is pushed by the first spring 13, the interception transverse column 15 moves towards the top body block 20, and finally the interception transverse column 15 is pulled out of the limit upright post 12, the moving process of the interception transverse column 15 is influenced by the negative pressure environment in the control post groove 16, because the inner diameter of the thin tube cavity 17 is small, the purpose of the design is that, even if the inner metal wire 19 is pulled by accident to keep a straight state, after pulling, the interception transverse column 15 is completely separated from the limit upright post 12, the elastic pushing of the second spring 21 enables the top body block 20 to press the inner metal wire 19 in time, and the inner metal wire 19 is ensured to reappear-shaped state and stick on the deformation plate 4, only if the inner metal wire 19 is actually pulled to the outside and is half passed, the process that the clamping cross column 15 is pulled out from the limiting upright post 12 is finally triggered, so that the limiting upright post 12 is elastically pushed by the elastic metal sheet 11, the limiting upright post 12 moves the control body 35, the control body 35 rotates, the wire 18 is pulled by moving one end of the control body 35, finally, the inner metal wire 19 is completely pulled out from the wiring board block 2, the automatic disconnection work is realized, the screw 36 has the effect of fastening the control body 35 and the wiring board block 2, and after the wiring board block 2 is put into use, the screw 36 needs to be taken down.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
