Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the switch cabinet with the height-adjustable chassis comprises a chassis 10, wherein the chassis 10 comprises an upper surface 11, a lower surface 12 and side surfaces, and the side surfaces comprise a left side surface 13 and a right side surface 14; a support member 2, the support member 2 being vertically movable between the upper surface 11 and the lower surface 12, the support member 2 projecting from the upper surface 11 and being fixable in a raised position when the support member 2 is in the raised position; when the support member 2 is in the lowered position, the support member 2 is located between the upper and

lower surfaces

11, 12 and the upper end of the support member 2 does not protrude from the upper surface 11. The upper surface 11 is provided with a through slot 15, and the support member 2 can be lifted or dropped in the through slot 15.

The lifting device further comprises a handle 3, wherein the handle 3 is connected to the support 2, and when an operator applies force to the handle 3, the lifting or falling state of the support 2 can be switched. In this embodiment, the support member 2 and the handle 3 are detachably connected. The handle 3 comprises a first handle 31 and a second handle 32, and the first handle 31 and the second handle 32 are respectively arranged at the left side and the right side of the chassis.

The support member 2 comprises a lateral portion 201 and a vertical portion 202, the lower end of the lateral portion 201 being abuttable against the upper surface 11 of the chassis when the support member 2 is in the raised position, thereby securing the support member 2 in the raised position.

The number of the through grooves 15 is four, and the four through grooves are respectively a first through groove 151, a second through groove 152, a third through groove 153 and a fourth through groove 154; the supporting members 2 are provided with four corresponding through grooves, namely a first supporting member 21, a second supporting member 22, a third supporting member 23 and a fourth supporting member 24, and the four supporting members can be lifted in the four through grooves respectively. The first and second through

grooves

151 and 152 are disposed at positions close to the left side surface 13, and the third and fourth through grooves 153 and 154 are disposed at positions close to the right side surface 14. The first and

second supports

21 and 22 are connected to the first handle 31 by a link, and the third and

fourth supports

23 and 24 are connected to the second handle by a link.

The left side surface 13 is provided with a first avoiding groove 16, a first handle 31 penetrates through the first avoiding groove 16, the hand-held part of the first handle 31 is positioned outside the chassis, and the first handle 31 can slide in the first avoiding groove 16. A second abdicating groove (not shown in the figure) is arranged on the right side surface 14, the second handle 32 passes through the second abdicating groove, the holding part of the second handle 32 is positioned outside the chassis, and the second handle 32 can slide in the second abdicating groove. The first and second abdicating grooves 16 and 32 are L-shaped, and the first and second handles 31 and 32 can slide in the first and second abdicating grooves 16 and 32 in the transverse and longitudinal directions, respectively.

In this embodiment, the left side surface 13 and the right side surface 14 are respectively provided with a guide piece 17, and the end part of the guide piece 17 extends upwards in an inclined manner, so that the chassis can enter the switch cabinet body more conveniently when entering the switch cabinet body. Four rollers 18 are correspondingly arranged below the four end parts of the chassis 10, so that the chassis can bear the breaker to be pushed in or pushed out conveniently.

In actual operation, when the contact 101 of the circuit breaker 100 needs to be connected with a contact box with a short height, the circuit breaker is directly placed on the chassis, so that the lower end of the circuit breaker contacts with the upper surface of the chassis, and referring to fig. 1, the circuit breaker can be conveyed to the inside of a switch cabinet body by using the trolley connection chassis. When the contact 101 of the circuit breaker 100 needs to be connected with a contact box with a high height, an operator manually applies force to the handle 3, first pulls the handle 3 upward in the vertical direction, at this time, the supporting member 2 is lifted from the through groove 15, when the transverse part 201 of the supporting part 2 is lifted out of the through groove 15, the handle is pulled transversely forwards, so that the transverse part 201 of the supporting part 2 moves transversely until the vertical part 202 abuts against the edge of the through groove 15, the handle 3 is put down, the lower end of the transverse part 201 can abut against the upper surface 11 of the chassis, so that the supporting part 2 is fixed at a lifting position and cannot move downwards, the circuit breaker 100 is then placed on the chassis 10, such that the lower end of the circuit breaker 100 contacts the upper end of the support 2, then the trolley is connected with the chassis to convey the breaker into the cabinet body of the switch cabinet, and the height of the breaker is increased under the action of the supporting piece 2, so that the breaker can be used for connecting a contact box with higher height. When the contact box with higher height needs to be connected, only the higher supporting piece needs to be replaced, a chassis with higher height does not need to be purchased again, the universality is strong, and the cost is saved.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
