Bed frame connecting structure and bed frame

Abstract

A support leg and a connecting rod in the present invention are fixed together through fitting between an insertion portion and a wedge-shaped insertion slot. When subjected to external omnidirectional pressure, the insertion portion can go lower and fit tighter, making a gap smaller without wobbling, thus allowing for a simple structure with good stability.

1 . A bed frame connecting structure, comprising a support leg and a connecting rod, wherein an end of the connecting rod is provided with a connector, a side wall of the support leg is fixedly connected to a clamping member, the clamping member comprises a first side plate, a second side plate, a third side plate, and a fourth side plate, the first side plate is opposite the fourth side plate, the first side plate and the fourth side plate are both connected fixedly or integrally to one of side walls of the support leg, the second side plate is connected fixedly or integrally to a side of the first side plate away from the support leg, the third side plate is connected fixedly or integrally to a side of the fourth side plate away from the support leg, a side of the second side plate away from the first side plate and a side of the third side plate away from the fourth side plate are connected fixedly or integrally, the second side plate and the third side plate form an acute angle, the first side plate, the second side plate, the third side plate, the fourth side plate, and the side wall of the support leg jointly enclose an insertion slot that communicates vertically, an outer contour of a cross section of the insertion slot is pentagonal, the connector comprises a first connector and a second connector that are connected integrally, the second connector comprises a first plate, second plates fixedly connected in one-to-one correspondence to two sides of the first plate, and third plates fixedly connected in one-to-one correspondence to sides of the second plates away from the first plate, the first plate, the two second plates, and the two third plates jointly enclose a hollow insertion portion, the first connector is fixedly connected to an end of the connecting rod, the insertion portion is inserted into the insertion slot, an outer peripheral surface of the insertion portion closely fits with an inner side surface of the insertion slot, an outer contour of a cross section of an opening of the insertion slot remains unchanged, and the first side plate, the second side plate, the third side plate, and the fourth side plate gradually decrease in dimension from one end facing the connecting rod to the other end. 
     
     
         2 . The bed frame connecting structure according to  claim 1 , wherein the first connector comprises a connecting plate and limiting plates fixedly connected in one-to-one correspondence to two sides of the connecting plate, the connecting plate and the two limiting plates jointly enclose a positioning groove, and an end of the connecting rod is fixed and connected through insertion in the positioning groove. 
     
     
         3 . The bed frame connecting structure according to  claim 1 , wherein the connecting rod is a square rod. 
     
     
         4 . The bed frame connecting structure according to  claim 1 , wherein an outer contour of a cross section of the support leg is in the shape of a right-angle sector. 
     
     
         5 . A bed frame, comprising the bed frame connecting structure according to  claim 1 .
