Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a quick-detachable caster for a cabinet. Background Art

[0002] Cabinets are common electrical equipment, mainly used to accommodate various electronic and electrical components. Depending on the installation scenario, some need casters, while others do not. However, casters are necessary during transportation. Existing casters are usually fixed to the cabinets with bolts. Since some cabinets need to be fixed for a long time, the casters affect the stability of the cabinets on the one hand, and are prone to damage if left still for a long time on the other hand. Therefore, the casters of these cabinets need to be removed when used. At present, the installation and removal of casters require the use of additional auxiliary tools and are time-consuming.

[0003] For example, the publication number CN202020225611.7 discloses "Quick-detachable casters for cabinets", in which the installation is completed by extending the card plate and the elastic button from the bottom of the bottom plate upward through the pick-up and release groove, and moving the limit plate from the aisle groove to the bottom to make the elastic button extend from the limit hole; when removing the caster, press down the elastic button, move the roller part along the aisle groove to move the card plate and the elastic case out of the gap, and move the roller part downward to the pick-up and release groove to complete the removal of the caster.

[0004] However, the above-mentioned loading and unloading method for casters has low stability, and the stability of caster installation and removal is poor. When subjected to gravity collision, a gap will be caused between the limit hole and the elastic case, which will lead to looseness. During subsequent installation, the casters will be very easy to fall off due to the previous damage, thereby affecting the stability and convenience of the cabinet. Utility Model Content
