Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to a switch cabinet frame and a switch cabinet. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Various components such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. need to be installed inside. Therefore, after the components inside the switch cabinet are installed, the curb weight is heavy. Once the switch cabinet frame is not installed firmly, the frame may shake, further resulting in a loose connection between the frame and the base, causing damage to the switch cabinet. In addition, the assembly between the various components of the switch cabinet frame is mostly fixed by bolts one by one. This connection method is cumbersome and the assembly firmness is not good. For this reason, we have launched a switch cabinet frame and switch cabinet. Summary of the invention

[0003] The object of the present invention is to provide a switch cabinet frame and a switch cabinet to solve the problems raised in the above background technology.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-13 , the present invention provides a technical solution:

[0039] Embodiment 1:

[0040] A switch cabinet frame comprises a column frame 3, a top cover 1 fixed at the upper and lower ends of the column frame 3, and a base mechanism, wherein the top of the column 31 is inserted into a slot at the lower end of the top cover 1, and a second screw 2 at the top of the top cover 1 penetrates the top cover 1 and is screwed to the corresponding top of the column 31.

[0041] The column frame 3 includes four groups of columns 31 fixed by cross frames 33. The cross section of the column 31 is L-shaped. The column 31 is provided with a connecting plate 32 integrally formed therewith. Several groups of cross frames 33 between adjacent columns 31 are distributed at equal intervals up and down, and the cross frames 33 are fixed to the corresponding connecting plates 32 by first screws.

[0042] The base mechanism comprises a base frame 5 and a reinforcement seat 4 fixed inside the base frame 5;

[0043] The base frame 5 includes a bottom frame 504 and an upper frame 501 fixed to the upper end of the bottom frame 504 by a snap fastener, and legs 503 are provided at the four corners of the lower end of the bottom frame 504, and the horizontal cross 505, the L-shaped socket 5112, the bottom frame 504 and the legs 503 are integrally formed;

[0044] The bottom frame 504 is rectangular, and the outer end of the horizontal cross 505 is fixed at the corner of the opening inside the bottom frame 504 to reinforce the bottom frame 504 and enhance the structural strength of the bottom frame 504;

[0045] The snap-fitting member includes a plurality of vertical plates 507 fixed to the upper end of the bottom frame 504 and a snap-fitting protrusion 514 on the outer top of the vertical plate 507 . The inner wall of the upper frame 501 is provided with a first snap-fitting groove 510 for snapping the snap-fitting protrusion 514 .

[0046] The upper corner of the bottom frame 504 is provided with a plug socket 511 for inserting into the plug slot 502 at the corner of the upper frame 501. After the bottom of the column 31 is inserted into the plug slot 502 and seated on the upper end of the plug socket 511, the tensioning buckle mechanism on the plug socket 511 is buckled and fixed with the inner wall of the plug slot 502 under the pressure of the column 31;

[0047] The socket 511 includes an L-shaped socket 5112 fixed to the upper end of the bottom frame 504 and a sealing cover 5111 fixed to the top of the L-shaped socket 5112;

[0048] The tensioning buckle mechanism includes a hemispherical airbag 512 fixed to the middle of the upper end of the sealing cover 5111, a snap plate 516 slidably connected to the sliding grooves 515 on both sides of the L-shaped socket 5112, and a tensioning bag 517 arranged inside the sliding grooves 515;

[0049] The tensioning bag 517 is connected to the air outlet pipe 520 at the middle of the lower end of the hemispherical air bag 512 through a pipe 519, and the tensioning bag 517 is located at the inner side end of the buckle plate 516;

[0050] After the bottom of the column 31 is seated on the upper end of the socket 511, the hemispherical airbag 512 is subjected to the pressure of the column 31, so that the internal gas of the hemispherical airbag 512 is filled into the tensioning bag 517 through the outlet pipe 520 and the pipeline 519. After the tensioning bag 517 expands, it pushes the outer end of the snap plate 516 to extend out of the sliding groove 515 and then snap into the second snap groove 5021 on the inner wall of the plug-in groove 502.

[0051] The two sides of the inner end of the sliding groove 515 are provided with limiting grooves 518, and the limiting protrusions 521 fixed on the two sides of the inner end of the snap plate 516 are slidably connected in the corresponding limiting grooves 518, and the second spring 522 provided inside the limiting groove 518 abuts against the side wall of the outer end of the limiting protrusion 521. In this arrangement, in the initial state, the snap plate 516 is retracted into the sliding groove 515 under the elastic force of the second spring 522, preventing the outer end of the snap plate 516 from extending out of the sliding groove 515, which can ensure that the plug seat 511 is smoothly inserted into the bottom of the plug through groove 502;

[0052] The reinforcing seat 4 includes a reinforcing plate 41, a limiting seat 43 arranged at the four corners of the reinforcing plate 41, and an oblique support 42 arranged on both sides of the upper end of the limiting seat 43. The reinforcing plate 41 is also provided with an entry hole 44. The fastening bolt 45 in the middle of the reinforcing plate 41 is screwed to the horizontal cross 505 in the middle of the bottom frame 504, so that the clamping plate 46 at the end of the oblique support 42 slides into the clamping groove 34 on the side of the column 31, and the limiting seat 43 is clamped in the fixing groove 509 on the inner wall of the upper frame 501. The limiting seat 43 pushes the plug-in mechanism on the upper frame 501 to achieve plug-in fixation with the column 31.

[0053] The lower end of the upper frame 501 is provided with a groove 5013 located between the fixing groove 509 and the insertion groove 502, and the top of the groove 5013 is provided with a raised seat 5014;

[0054] The plug-in mechanism includes a connecting rod 5011 penetrating the protruding seat 5014 and an inserting block 506 and a pushing block 508 screwed at both ends of the connecting rod 5011, and a first spring 5012 sleeved on the connecting rod 5011 is located between the protruding seat 5014 and the pushing block 508;

[0055] like Figure 5 As shown, under the elastic force of the first spring 5012, one end of the push block 508 extends into the fixing groove 509 through the groove 5013, and one end of the insert block 506 extends into the groove 5013 through the plug-in slot 502, and the other end surface of the insert block 506 is flush with the inner wall of the plug-in slot 502;

[0056] An inclined surface is provided at the top of one end of the push block 508 extending into the fixing groove 509 , and an inserting block groove 35 for inserting the inserting block 506 is provided at the bottom side of the column 31 .

[0057] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a switch cabinet, including the frame of the switch cabinet.

[0058] Specifically, when in use, the upper frame 501 is placed on the upper end of the bottom frame 504. Under the gravity of the upper frame 501, the upper frame 501 moves downward until the buckle protrusion 514 on the vertical plate 507 is buckled into the first buckle groove 510 on the inner wall of the upper frame 501. At the same time, the plug socket 511 on the bottom frame 504 is accurately inserted from the bottom of the plug-in slot 502 into the bottom of the plug-in slot 502, thereby achieving the preliminary fixation of the bottom frame 504 and the upper frame 501.

[0059] The reinforcing plate 41 is placed on the upper end of the base frame 5, so that the limiting seat 43 on the reinforcing plate 41 is stuck in the fixing groove 509 on the inner wall of the upper frame 501. At this time, under the elastic force of the first spring 5012, the push block 508 will not move. In this way, under the self-weight of the reinforcing seat 4, the limiting seat 43 is still supported on the inclined surface of the push block 508;

[0060] Then, the bottom of the column 31 is inserted from above the plug-in slot 502 into the corresponding plug-in slot 502, and the clamping plate 46 at the end of the diagonal support 42 is closely attached to the side wall of the column 31 until the bottom of the column 31 is seated on the upper end of the plug-in seat 511. Under the gravity of the column 31, the hemispherical airbag 512 is subjected to the pressure of the column 31, so that the internal gas of the hemispherical airbag 512 is filled into the tensioning bag 517 through the air outlet pipe 520 and the pipeline 519. After the tensioning bag 517 expands, it pushes the outer end of the clamping plate 516 to extend out of the sliding slot 515 and then clamp into the second clamping slot 5021 on the inner wall of the plug-in slot 502. In this way, after the column 31 is installed, the bottom frame 504 and the upper frame 501 are further fixed again.

[0061] Then, the cross frame 33 is fixed to the corresponding connecting plate 32 by using the first screw to realize the assembly of the column frame 3;

[0062] Then, the fastening bolts 45 are locked and fixed to the horizontal cross 505 on the bottom frame 504. Under the locking action of the fastening bolts 45, the limit seat 43 moves downward along the inclined surface of the push block 508 until the limit seat 43 is completely inserted into the fixing groove 509.

[0063] At this time, if Fig.13As shown, since the limiting seat 43 moves downward along the inclined surface of the push block 508, the push block 508 is completely retracted into the groove 5013. At this time, the first spring 5012 is in a compressed state, and the push block 508 pushes the plug block 506 out of the groove 5013 through the connecting rod 5011 until the plug block 506 is completely inserted into the plug block groove 35 on the side of the bottom of the column 31, thereby achieving the fixation of the bottom of the column 31 and the upper frame 501;

[0064] Under the locking action of the fastening bolts 45, and after the limiting seat 43 is completely inserted into the fixing groove 509, the reinforcing plate 41 drives the clamping plate 46 at the end of the diagonal brace 42 to move downward along the side wall of the column 31 until the clamping plate 46 is inserted into the clamping groove 34 of the side wall of the column 31, so that the diagonal brace 42 forms an inclined support between the column 31 and the upper frame 501, further strengthening the firmness of the connection between the column 31 and the upper frame 501, and preventing the column frame 3 from tilting and shaking on the base frame 5;

[0065] Finally, the top cover 1 is screwed to the top of the corresponding column 31 using the second screw 2 to further strengthen and fix the column frame 3.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
