Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of back cabinets, in particular to an adjustable back cabinet. Background Art
[0002] Back cabinets are a type of cabinet, which are mostly made of wood. The back cabinets are usually separated by partitions to form corresponding storage spaces, and back cabinets of different specifications also have different structures.
[0003] For example, when the number of books placed in a household cabinet exceeds 50% of the cabinet's volume, it means that there are too many books on the cabinet, and it is difficult to move the cabinet. Traditional cabinets with a height of less than 1.4 meters usually have universal wheels at the bottom to meet the need for mobility. However, when actually moving the cabinet, it is found that if the cabinet is heavy, the force will be concentrated on the wheel body when turning, and the wheel body is very easy to be damaged. Therefore, the universal wheels for cabinets with a height of less than 1.4 meters cannot meet the needs of use, not to mention the larger cabinets. Utility Model Content
[0004] The utility model provides an adjustable back cabinet, which overcomes the shortcomings described in the background technology.
[0005] The technical solution adopted by the utility model to solve its technical problem is:
[0006] An adjustable back cabinet comprises side panels, a top panel, a bottom panel and an adjustment seat. The side panels are spliced with the top panel and the bottom panel, and reinforcement members are arranged at the splicing positions of the side panels and the top panel. A plurality of slots are arranged on the side panels, and partitions are clamped on the slots. The bottom end of the bottom panel is connected to the adjustment seat. The adjustment seat comprises a connecting plate and a base. A connecting groove is arranged on the base. A convex block is arranged on the side end of the connecting plate and is clearance-matched with the connecting groove. Support feet are symmetrically arranged on the base. A sealing sheet is arranged on the top of the supporting feet, and an oil groove is arranged on the top of the sealing sheet. An inlet pipeline and a connecting oil path which are connected with the oil groove are arranged in the base. The inlet pipeline extends to the outer side surface of the base, and one end of the connecting oil path is connected with the connecting groove. The maximum size of the base is smaller than the size of the bottom panel.
[0007] The back cabinet structure in the utility model is provided with an adjustment seat on the bottom plate. First, the top of the connection plate is locked and installed on the bottom plate, and a convex block is provided on the side end of the connection plate to ensure that the connection plate is always connected to the base. The position where the connection plate and the base rotate together is filled with oil. The oil is used to lubricate the rotating part on one hand, and on the other hand, when the supporting foot contacts the ground, the oil in the oil tank is squeezed upward to achieve a buffering effect.
[0008] The adjustment seat in the utility model is arranged at a certain distance from the outer side surface of the bottom plate, so that when the adjustment seat contacts the ground, sufficient space is reserved at the corner of the bottom plate, which is convenient for placing hands during transportation.
[0009] A better technical solution: a one-way valve is set on the inlet pipeline, and a sealing plug is set at the outer end of the inlet pipeline. The one-way valve ensures that the oil flows from the outside to the inside in one direction, and the internal oil will not flow out from the inlet pipeline.
[0010] A better technical solution: the supporting feet are made of rubber, and the supporting effect and use cost are appropriate.
[0011] A better technical solution: a reinforcement piece is provided at the joint of the bottom plate and the top plate to strengthen the connection strength at the joint of the back cabinet frame.
[0012] A better technical solution: an inlet pipeline is set on the base, and the two oil tanks are connected to each other. Compared with setting two inlet pipelines, this solution has lower manufacturing costs and can meet basic usage requirements.
[0013] A better technical solution: two inlet pipelines are arranged on the base, and two oil tanks are arranged independently.
[0014] A preferred technical solution: a universal wheel is arranged at the side end of the adjustment seat, and the top end of the universal wheel is locked and connected with the bottom plate.
[0015] A preferred technical solution: the bottom end of the universal wheel is lower than or higher than the bottom end of the supporting foot.
[0016] Universal wheels are set on the basis of the adjustment seat to improve the adjustment range of the back cabinet, which is not limited to the convenient steering and efficient support brought by the adjustment seat. When the universal wheel moves, due to the existence of the adjustment seat, on the one hand, even if the universal wheel is damaged, the back cabinet as a whole will not fall over; on the other hand, since the adjustment seat is set at a distance from the bottom plate, there is no risk of the back cabinet pressing the foot. When the bottom of the universal wheel is lower than the bottom of the supporting foot, the back cabinet can be moved by the universal wheel, otherwise, the back cabinet is in a supported state. The relative relationship between the universal wheel and the supporting foot can be indirectly adjusted by changing the amount of oil in the adjustment seat.
[0017] By adopting the above technical solution, the beneficial effects of the utility model are:
[0018] The utility model provides an adjustment seat at the bottom end, and a spacing is set between the adjustment seat and the outer edge of the bottom plate. At the same time, the adjustment seat has a certain height, which is convenient for carrying the back cabinet; the connecting plate in the adjustment seat is rotatably matched with the base, so that the back cabinet as a whole can be flexibly rotated and adjusted. At the same time, supporting feet that use oil as a buffer are provided on the base, and the supporting effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
