Description

Technical Field

[0001] This utility model relates to the field of box body accessories technology, and in particular to a left and right door switching structure for a box body. Background Technology

[0002] In the design of various cabinet equipment such as refrigerators, freezers, display cases, toolboxes, and electrical control cabinets, the hinge structure of the door is a key component for realizing the opening and closing function of the cabinet. Traditional cabinet doors are usually connected to one side of the cabinet using fixed hinges, and the opening direction is determined during manufacturing or installation, making it impossible to flexibly switch according to actual usage scenarios.

[0003] To meet users' needs for adjustable door opening direction, some cabinet door structures capable of switching between left and right opening have been developed in existing technologies. A common approach is to install hinge seats on corresponding positions on both sides of the door and the cabinet, allowing the door opening direction to be switched by removing a hinge from one side and installing it on the other. However, this method is cumbersome, requires tools, and frequent disassembly and reassembly can easily lead to lost or damaged parts, resulting in a poor user experience.

[0004] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0005] This utility model overcomes the shortcomings of the prior art and provides a left and right door switching structure for a box that is simplified in structure, easy to assemble and disassemble, and has reliable positioning.

[0006] This utility model is achieved through the following technical solution:

[0007] A left-right opening and switching structure for a cabinet includes a cabinet and a door connected to the cabinet. The left and right sides of the door are slidably connected to shafts that can extend from the ends of the door. Handles are also rotatably connected to the left and right sides of the door. A linkage structure is provided between the handles and the shafts, allowing the shafts to retract into the cabinet when the handles are rotated. A reset structure is provided between the shafts and the door, allowing the shafts to return to their original position and extend out of the door. Connecting seats are provided on the left and right sides of the cabinet. Each connecting seat has a connecting hole into which the shafts extend, allowing the door to rotatably connect with the cabinet. The connecting seat also has a front-opening positioning groove, with the connecting hole located at the bottom of the positioning groove. The end of the door also has a positioning shaft head that can slide into the positioning groove from the front for positioning, allowing the shaft to smoothly extend into the connecting hole.

[0008] As described above, the left and right door switching structure of the box body is provided with a guide structure on the door body that can guide the sliding of the shaft.

[0009] As described above, the left and right door switching structure of the box includes a linkage structure comprising a toggle block rotatably connected to the door body in the middle and a push block connected to the handle and pushing the toggle block to rotate when the handle is rotated. The shaft is provided with a driving structure that can be pushed by the toggle block to drive the shaft to slide.

[0010] As described above, in a left-right door switching structure for a housing, the driving structure includes a slot on a shaft, and one end of the lever extends into the slot.

[0011] As described above, a left-right door switching structure for a box body includes handle seats on its left and right sides, the handles are rotatably connected to the handle seats, one end of the reset structure is connected to the handle seats, and the other end is connected to the end of the shaft.

[0012] As described above, in a cabinet with a left-right door switching structure, the upper and lower sides of the cabinet are provided with connecting seats, and the shaft includes an upper shaft that can extend from the upper end of the door and a lower shaft that can extend from the lower end of the door.

[0013] As described above, in a left-right door switching structure for a housing, the end of the positioning shaft head is provided with a through hole for the shaft rod to pass through.

[0014] As described above, in a left-right door switching structure for a housing, the connecting seat has a protrusion, and the positioning groove is located on the protrusion.

[0015] As described above, in a cabinet with a left and right door switching structure, the reset structure includes a reset spring.

[0016] In the left-right door switching structure of the cabinet described above, the toggle block is L-shaped.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This invention uses a positioning shaft head and a positioning groove for positioning. The positioning shaft head at the end of the door slides into the positioning groove through the front open end to form a pre-position, ensuring that the shaft and the connecting hole are in the same axial direction. The operator does not need to adjust the left and right position of the door and the angle of the shaft at the same time. Simply sliding the positioning shaft head into the positioning groove can automatically complete the precise alignment of the shaft and the connecting hole, significantly reducing the complexity of installation.

[0019] The handle and shaft are integrated and linked. By turning the handle on one side, the linkage structure can be triggered to drive the shaft on the same side to retract into the door. At the same time, the reset structure can automatically keep the shaft on the other side extended, thus enabling the door to switch opening direction. Releasing the handle will cause the shaft on the target side to pop out and insert into the connection hole. No additional tools or parts need to be disassembled throughout the process.

[0020] The reset mechanism forces the shaft to remain extended out of the door body when not in operation, preventing the shaft from accidentally disengaging from the connection hole and causing the door to loosen. Furthermore, damage to one side of the mechanism will not affect the normal function of the other side. Attached Figure Description
