The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a decoupler for SPD interstage energy matching comprises a decoupler body 1, wherein a mounting groove 101 penetrating through the left side and the right side of the decoupler body 1 is horizontally and transversely formed in the middle of the rear side of the decoupler body 1, two through holes a 102 are formed in symmetrical positions of the left side wall and the right side wall of the decoupler body 1, two through holes B103 are formed in the rear wall of the decoupler body 1, which is located inside the mounting groove 101, the two through holes B103 are vertically symmetrical and respectively abut against the upper side and the lower side of the mounting groove 101, and the two through holes B103 and the two through holes a 102 are formed at the same height; the installation groove 101 is provided with two B through holes 103, the two B through holes 103 are formed in the installation groove 101, the two B through holes are symmetrically and fixedly provided with fixed clamping pieces 2, the two fixed clamping pieces 2 correspond to the two B through holes 103, each fixed clamping piece 2 is formed by integrally bending a vertical piece and a slope piece, the included angle of each vertical piece is an obtuse angle, flexibility exists between the vertical piece and the slope piece, the slope piece can be bent by taking the end part of the vertical piece as an axis, the whole fixed clamping piece 2 is L-shaped, the vertical piece and the inner wall of the installation groove 101 are vertically and fixedly installed together, the slope piece penetrates through the B through holes 103 and extends into the decoupler body 1, one end of the slope piece, located outside the decoupler body 1, is fixedly provided with a limiting block 201, and one end; the vertical section of the limiting block 201 is in a right trapezoid shape, the inclined surface of the limiting block faces the outer side of the mounting groove 101, so that the clamping rail 3 of the electric box can be more conveniently extruded into the mounting groove, and the shifting lever 202 is in a round rod shape, horizontally extends outwards from the left side and the right side of the fixed clamping piece 2, and penetrates through the A through hole 102 to extend to the outer part of the decoupler body 1.

Through the technical scheme, when the decoupler body 1 is installed, the electric box clamping rail 3 is firstly aligned to the position between the two fixed clamping pieces 2, the decoupler body 1 is then moved until the cabinet rail 3 is completely squeezed between the two fixed jaws 2 (i.e. the process shown in figures 2 to 3), during the process, the upper side and the lower side of the electric box clamping rail 3 extrude the included angle between the vertical piece and the slope piece of the two fixing clamping pieces 2 into a right angle from an obtuse angle, and when the electric box clamping rail 3 is completely squeezed between the two fixed clamping pieces 2, the limiting block 201 can limit the movement of the electric box clamping rail 3, so as to prevent the electric box clamping rail 3 from being disconnected with the decoupler body 1, and simultaneously, the two fixed clamping pieces 2 can generate huge reaction force after being squeezed and bent, therefore, the electric box clamping rail 3 is firmly clamped, the firmness is very strong, and the fixed installation of the decoupler body 1 and the electric box clamping rail 3 is realized;

when the decoupler body 1 needs to be disassembled or adjusted, the shift levers 202 located at the upper and lower sides need to be shifted towards the direction away from each other along the through holes a 102 where the shift levers are located respectively, at this time, the shift levers 202 simultaneously drive the two fixing clips 2 to bend, so that the included angle between the vertical piece and the slope piece of the two fixing clips 2 is bent into an acute angle from a right angle, until the two fixing clips 2 are no longer in contact with the electric box clamping rail 3, and at the same time, the limit block 201 no longer limits the movement of the electric box clamping rail 3 (i.e. the process shown in fig. 3 to fig. 4), at this time, the decoupler body 1 can be disassembled from the electric box clamping rail 3, and at this time, because the electric box clamping rail 3 is no longer clamped by the two fixing clips 2, the installation position of the decoupler body 1 can be adjusted arbitrarily, after the adjustment is completed, all the shift levers 202 are loosened, so that the two fixing clips 2 are reset, thereby the electric box clamping rail 3 is, so that the decoupler body 1 is also mounted again with the cabinet clamping rail 3.

Further, as shown in fig. 1, the through hole a 102 is arc-shaped, and the shape matches with the motion track of the shift lever 202 when the fixed clip 2 is bent, so as to ensure smooth shifting of the shift lever 202, and the through hole a 102 is provided with a dust plug, so that external dust can be effectively prevented from entering the interior of the decoupler body 1 through the through hole a 102 by the blocking effect of the dust plug on the through hole a 102.

Furthermore, the outer diameter of the deflector rod 202 is equal to the width of the through hole A102, so that the mounting structure between the deflector rod 202 and the through hole A102 is more compact and more stable without loosening, and a rubber cap is sleeved at one end of the deflector rod 202 extending out of the decoupler body 1, so that the effects of skid resistance, insulation and hand feeling enhancement are achieved.

Further, fixed clamping piece 2 and stopper 201 are made by 301 stainless steel, and this material has fine ductility, wearability and fatigue strength to the rubber membrane has all been pasted to the outward appearance of the two, has played the effect of insulating and reinforcing and the electric box card between the rail 3 friction power, and then make the installation of electric box card rail 3 and decoupler body 1 more firm.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
