As a preferred arrangement of the axial notch 1144, the axial notch 1144 is designed as a straight deformed groove and has a width C set to 0.25 times the diameter D4 of the third land 1143. When the second rotation engaging member 114 is installed, the second rotation engaging member 114 can be deformed radially through the axial notch 1144, so that it can be smoothly connected to the connection hole 1132; when the second engaging rotating member 114 is connected in place, the third boss 1143 is deformed under the action of the elastic force, so that the circumferential upper surface of the third boss can be completely abutted to the bottom of the elastic claw structure 1134, thereby effectively ensuring the restraining effect of the third boss and further effectively preventing the falling problem.

Continuing to refer to fig. 15, as shown in fig. 15, the second cylindrical body 1141 is further provided with three annular supporting ribs 1145, the three annular supporting ribs 1145 are located between the second boss 1142 and the third boss 1143, and the second cylindrical body 1141 is connected to the connection hole 1132 through the three annular supporting ribs 1145, so that the second engaging rotating member 114 can be smoothly connected to the connection hole 1132, and meanwhile, the supporting strength can be effectively improved, and the connection reliability can be effectively ensured. As a preferable arrangement, the outer diameters of the three annular support ribs 1145 decrease in sequence along the direction from the second boss 1142 to the third boss 1143 (i.e., the direction from top to bottom in fig. 15), and further, the outer diameters are preferably set to decrease by 1mm at equal intervals, so that the supporting force can be decreased by small and large, and thus sufficient supporting force can be provided to meet the design requirement. In addition, it should be noted that the specific shape, number, size and distribution of the annular supporting ribs 1145 can be set by a skilled person according to actual use requirements, for example, the annular supporting ribs 1145 may be a whole ring, or a plurality of circular arc segments which are annular as a whole, which is not limited.

With reference to fig. 13 to 15, taking the aperture of the first mounting hole 1112 as D and the aperture of the second mounting hole 1121 as D1 as an example, of course, a technician can set specific values of the aperture D of the first mounting hole 1112 and the aperture D1 of the second mounting hole 1121 according to actual use requirements to meet different connection strength requirements, and the sizes of the first engaging rotating member 113 and the second engaging rotating member 114 are preferably set as follows: the diameter D6 of the second boss 1142 is set to be 2mm larger than the aperture D1 of the second mounting hole 1121 in order to effectively fix the second snap rotating member 114 to prevent it from falling off; the diameter D5 of the second cylindrical main body 1141 is set to be 0.5mm smaller than the aperture D1 of the second mounting hole 1121, so that a gap margin is left between the second cylindrical main body 1141 and the hole wall of the second mounting hole 1121, so that smoothness of the rotating process is effectively ensured, and meanwhile, the problem that the shaking phenomenon is obvious due to the fact that the shaking amount is too large in the rotating process due to too large gaps can be effectively avoided, and further, the overall assembling effect is effectively ensured; the height H2 of the second cylindrical body 1141 serving as an effective connecting shaft section is set to be 1-2 mm greater than the height of the constrained part (namely, the box cover 112 part and the first clamping rotating member 113), namely, the height H2 is set to be 1-2 mm greater than the sum of the plate thickness t of the box cover 112 and the height H3 of the first clamping rotating member 113, so that after the second cylindrical body is connected in place, the elastic claw structure 1134 of the first clamping rotating member 113 can be unfolded to a natural state, so that the integral constraint effect is effectively ensured, and the connecting strength is improved; the aperture D9 of the connection hole 1132 is set to be equal to the diameter D5 of the second cylindrical body 1141, so as to effectively provide sufficient supporting force; the diameter D8 of the first boss 1133 is set to be 4mm larger than the hole diameter D of the first mounting hole 1112 to prevent the first snap rotation member 113 from falling off; the diameter D11 of the first cylindrical body 1131 is set to be 0.5mm smaller than the diameter D of the first mounting hole 1112, so that the first snap-fit rotating member 113 can be quickly restored to a natural state after being mounted in place, and the overall assembly effect is effectively improved; the outer diameter D10 of the elastic claw structure 1134 is set to be 4mm larger than the aperture D of the first mounting hole 1112, so as to further achieve the effect of preventing falling off, and further effectively ensure that the first engaging rotating member 113 and the second engaging rotating member 114 can maintain a stable and reliable connection relationship. It should be noted that the above size setting mode is only a preferred setting mode, and technicians may set their specific size according to actual use requirements; such changes in the specific dimensions do not depart from the basic principle of the present invention and shall fall within the scope of the present invention.

Based on the structural arrangement of the first engaging rotation member 113 and the second engaging rotation member 114, the specific assembly method is as follows: first, the first engaging rotating member 113 is engaged with the first mounting hole 1112, so that the first engaging rotating member 113 is connected to the box 111; aligning the connection hole 1132 on the first engaging rotation member 113 with the second mounting hole 1121, and then sequentially passing the second engaging rotation member 114 through the second mounting hole 1121 and the connection hole 1132 to realize fixation; finally, another set of the first engaging rotating member 113 and the second engaging rotating member 114 is assembled in place according to the above assembling method; at this time, both upper and lower ends of the cover 112 are connected to the case 111, so that the cover 112 can stably and freely rotate with respect to the case 111. First block rotating member 113 and second block rotating member 114 are swift two-way operation structure, it can realize the assembly of box 111 and case lid 112 fast, also can realize dismantling fast simultaneously, need change it when, also need not with the help of any instrument, bare-handed can carry out quick assembly disassembly, the convenience of operation has greatly been promoted, the use of kit has been saved, and it still has with low costs, advantages such as reliability height, even if need change also need not to consume too much cost, more can not cause any damage to box 111 and case lid 112, help promoting electric cabinet 11's whole life.
