Problems solved by technology

Although the tensioning device for the flap door of the steam cabinet is used for the flap door of the traditional steam cabinet, there is indeed an excessively large tension spring stroke. Small, if the flap door is not closed tightly, steam will leak out, and there is always an unsatisfactory state

Embodiment Construction

[0008] See attached picture,

[0009] Pulley fixed plate 6 adopts screw, nut 12 to be fastened on cabinet door post 10 installation hole positions. 9 is the compression spring fixing frame, the compression spring 8 is sleeved on the shaft of the fixing frame, and then inserted into the limit hole of the door leaf fixing plate 7, and the hinge 2 is connected to the hinge hole position of the door leaf fixing plate by using the hinge screw 1 according to the required position. Finally, the installed door leaf fixing plate 7 is placed in the fixed positions on both sides of the flap and is fastened with the flap by screws. The connecting rod locking piece 3 is placed in the door flap chute and connected with the compression spring fixing frame 9 through screws, and then the compression spring is pre-pressed to the installation position with a special clamp, and then the connecting rod locking piece 3 is connected to the door leaf fixing plate with screws. 7 positioning connectio...

Abstract

The invention discloses a tension hinge structure of a steamer overhead door, which mainly comprises a pulley and an overhead door and is characterized in that a pulley fixing plate is fastened at a mounting hole of a steamer body doorpost through a fastening piece, a pressure spring is sleeved on a fixing frame shaft lever and is then inserted into a limit hole of a hinge fixing plate, a hinge is connected to a hinge hole of the hinge fixing plate through a hinge screw rod, and the hinge fixing plate is arranged at two sides of the overhead door and is fastened with the swinging door through a bolt. A connecting bar locking piece is arranged in a swinging sliding chute and is connected with a pressure spring fixing frame through a bolt. Compared with the traditional tension device of the overhead door, the invention can increase the pressing force of a door seal to ensure that steam in the steamer is not easily leaked, just discharges the steam when the overhead door is opened at 15 degrees without easily scalding the operating staff, can not occur the self-closing of the swinging door because the opening position with 90 degrees of the swinging is stable, and can not easily produce fatigue to reduce the tension of the pressure spring because the pressure spring is shorter, thereby the invention has great popularization value.

Description

technical field [0001] The invention relates to the technical field of tensioning mechanisms, in particular to a tensioning mechanism applied to a flap door of a steaming cabinet. Background technique [0002] At present, all kinds of commercially available steaming cabinet flaps adopt tensioning devices. Its basic structure is that the pulley fixing plate is fastened to the installation position of the pulley fixing plate on the door column of the steam cabinet with screws and nuts, and the tensioning connecting rod is installed in the connecting rod mounting holes on both sides of the flap using countersunk screws for fastening and connection, and then Pass the connecting rod through the sliding hole of the connecting rod on the door column of the steamer and press it into the chute of the pulley, and then use a tension spring of a specific length, one end is hung in the tension spring hook hole at the end of the connecting rod, and the other end is hung on the tension spr...
