Connecting device for push rod of bed frame

Abstract

A connecting device for a push rod of a bed frame is configured to connect a bedside drive rod and a bed-end drive rod of the bed frame. The connecting device contains: a fixing sheet, a coupling sheet, and at least one first locking element. The fixing sheet includes a first connection orifice fitted with the bedside drive rod or the bed-end drive rod, and at least one first lock orifice. The coupling sheet includes at least one second lock orifice and a joining portion. The at least one first locking element is inserted through the at least one first lock orifice of the fixing sheet and the at least one second lock orifice of the coupling sheet so as to connect the fixing sheet and the coupling sheet.

What is claimed is: 
     
         1 . A connecting device for a push rod of a bed frame being configured to connect a bedside drive rod and a bed-end drive rod of the bed frame, and the bed frame including a body and at least one movable transmission mechanism connected on the body, the at least one movable transmission mechanism including the push rod, and an end of the push rod being movably connected on the connecting device, the connecting device comprising:
 a fixing sheet including a first connection orifice defined on an end of the fixing sheet and fitted with the bedside drive rod or the bed-end drive rod, and at least one first lock orifice away from the first connection orifice;   a coupling sheet including at least one second lock orifice formed on a first end of the coupling sheet and corresponding to the at least one first lock orifice, and a joining portion formed on a second end of the coupling sheet and away from the at least one second lock orifice so as to connect with the push rod of the at least one movable transmission mechanism; and   at least one first locking element inserted through the at least one first lock orifice of the fixing sheet and the at least one second lock orifice of the coupling sheet to connect the fixing sheet and the coupling sheet.   
     
     
         2 . The connecting device as claimed in  claim 1 , wherein the fixing sheet further includes a second connection orifice is adjacent the at least one first lock orifice of the fixing sheet, and the coupling sheet includes a column extending beside the at least one second lock orifice and received in the second connection orifice, such that the coupling sheet is connected with the fixing sheet. 
     
     
         3 . The connecting device as claimed in  claim 1  further comprising at least one inverted U-shaped positioning seat, multiple second locking elements, and multiple second screw nuts; wherein a respective inverted U-shaped positioning seat includes a bottom fringe, two peripheral fences extending outward from the bottom fringe, and multiple third lock orifices defined on the bottom fringe; a bed-end stem of the body includes multiple passing orifices, wherein the multiple second locking elements are inserted through the multiple passing orifices and the multiple third lock orifices of the respective inverted U-shaped positioning seat to screw with the multiple second screw nuts, such that the push rod of the at least one movable transmission mechanism is connected between the at least one inverted U-shaped positioning seat and the joining portion of the coupling sheet. 
     
     
         4 . The connecting device as claimed in  claim 1 , wherein a bed-end stem of the bed frame includes at least one reinforcement member. 
     
     
         5 . The connecting device as claimed in  claim 1 , wherein the bedside drive rod includes an abutting block and two support shanks extending from two sides of the bedside drive rod; and the bed-end drive rod includes a contact protrusion and two locking pillars extending from two sides of the bed-end drive rod, wherein abutting block of the bedside drive rod corresponds to the contact protrusion of the bed-end drive rod. 
     
     
         6 . The connecting device as claimed in  claim 1 , wherein the fixing sheet is formed in an arcuate water drop shape, the coupling sheet is formed in an elongated arc shape, and a length of the coupling sheet is more than a length of the fixing sheet.
