Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of quick-release seat leg structure, and in particular to a quick-release seat leg structure. Background Technology
[0002] Existing seat structures are mostly fixed with metal connectors such as screws and bolts. This results in concentrated stress at the connection points, making them prone to deformation. Furthermore, the hardness of metal is greater than that of wood, which can cause the connection points of wooden seats to wear down and become unstable.
[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0004] A quick-release seat leg structure includes a seat armrest, four seat legs, two seat crossbars, and at least one crossbar connecting rod. The two ends of the seat crossbars are respectively inserted and fixed to the middle of the side of the seat legs, and the two ends of the crossbar connecting rods are inserted into the side of the seat crossbars. The lower end of the seat legs is inserted into the bottom of the seat armrest. A seat cushion is mounted on the seat crossbars and the crossbar connecting rods.
[0005] Preferably, the lower end face of the seat handle is provided with a stepped hole, and the upper end of the seat support leg is fixedly provided with an upwardly protruding insertion flange, which is inserted into the seat handle.
[0006] Preferably, a magnet is fixedly provided at the upper end of the insert flange, and an iron sheet is provided inside the stepped hole in the seat armrest for magnetic attraction and fixation with the magnet.
[0007] Preferably, the two ends of the seat crossbar are fixedly provided with connecting inserts, the middle part of the seat support leg is provided with a sliding groove and a socket communicating with the sliding groove and located below the sliding groove, the connecting insert is inserted laterally into the sliding groove and then slides down so that the lower end of the connecting insert is inserted into the socket to achieve a fixed connection, the upper end surfaces of the seat crossbar and the crossbar connecting rod are flush, and the seat cushion presses on the seat crossbar and the crossbar connecting rod to achieve compression fixation.
[0008] Preferably, the side wall of the seat crossbar is provided with a bend hanging groove, and right-angle bends are fixed at both ends of the crossbar connecting rod. The right-angle bends are inserted into the bend hanging groove and slide downward to a certain depth to achieve insertion and fixation.
[0009] Preferably, the outer surface of the right-angle elbow and the outer surface of the connecting plug are provided with a plastic coating or a rubber layer, which shrinks the gap after insertion and can prevent abnormal noise caused by frictional movement at the connection point during use.
[0010] The advantages and positive effects of this utility model are:
[0011] 1. The absence of metal materials in the connection effectively reduces costs, and the connection and assembly are simple and convenient. The structure is stable under stress, and the stress-bearing area at the connection is much larger than the screw engagement surface, which effectively improves the load-bearing strength. Furthermore, the use of rubber or plastic coating between the connection surfaces can reduce friction noise. Attached Figure Description
