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
The present invention relates to the strainer technical field, specifically, relate to a kind of strainer that is applied to structure of steamer overhead door.
Background technology
At present, commercially available all kinds of structure of steamer overhead door all are to adopt take-up device.Its basic structure is, the pulley fixed head adopts screw, nut to be fastened on steamer door pillar pulley fixed head installation site, tension linkage adopts sunk screw to be installed in the connecting rod installing hole of overhead door both sides and is fastenedly connected, again connecting rod is passed in the steamer door pillar connecting rod sliding eye and be pressed in the chute of pulley, adopt the extension spring of length-specific again, in the extension spring hook hole that hangs over the connecting rod tail end, the other end hangs over and bears in the bar extension spring hook hole, can open overhead door.Its operation principle is: the structure of steamer overhead door connecting rod after the installation connects by extension spring, when being opened, overhead door produces self-closing pulling force, and overhead door is when being opened to 90 °, extension spring and connecting rod axial angle are 0 °, make overhead door not produce self-closing pulling force, and connecting rod projection and pulley stop that overhead door can automatic ready opened and closed positions when leaning on.Use though the structure of steamer overhead door take-up device is traditional structure of steamer overhead door, really exist the extension spring stroke excessive, when selecting for use tension spring tension excessive, overhead door can produce self-closing phenomenon, is unfavorable for handling safety, and pulling force is less than normal, overhead door closes the steam that tightly can not leak, and has undesirable state all the time.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, be installed on steamer after, steamer body steam be difficult for to be leaked, and overhead door is difficult for taking place the tension hinge structure of steamer overhead door of self-closing phenomenon.
For achieving the above object, the present invention adopts following technical scheme: a kind of structure of steamer overhead door strainer, mainly form by pulley and overhead door, it is characterized in that: the pulley fixed head is fastened on cabinet door pillar position of mounting hole by securing member, stage clip is inserted on the fixed mount axostylus axostyle, insert in the door leaf fixed head spacing hole, hinge adopts the hinge screw rod to be connected door leaf fixed head pan position again, and the door leaf fixed head places fixed position, overhead door both sides fastening by screw and overhead door.The connecting rod stay places in the overhead door chute and is connected with the stage clip fixed mount by screw.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the present invention compares with traditional overhead door take-up device and has the following advantages: 1, can increase the gasket thrust, can make steamer body steam be difficult for leaking.2, correct position when overhead door is opened 15 °, discharged steam is difficult for making operating personnel to scald just.3,90 ° of enable possitions of overhead door are stable, are difficult for taking place the self-closing phenomenon of overhead door.4,, be difficult for to produce tired and reduce stage clip tension force because stage clip is shorter.Has promotional value.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing,
Pulley fixed head 6 adopts screw, nut 12 to be fastened on cabinet door pillar 10 position of mounting hole.9 is the stage clip fixed mount, stage clip 8 is inserted on the fixed mount axostylus axostyle, insert in again in door leaf fixed head 7 spacing holes, hinge 2 adopts hinge screw rods 1 to be connected door leaf fixed head pan position in the position on request, after door leaf fixed head 7 after will installing place fixed position, overhead door both sides fastening by screw and overhead door.Connecting rod stay 3 places and is connected with stage clip fixed mount 9 by screw in the overhead door chute, adopt special fixture that stage clip is pre-stressed to the installation site then after the employing screw connecting rod stay 3 and door leaf fixed head 7 are located by connecting.Turning over door hange sheet and the connecting rod stay after installing, put into the pulley fixed head 6 after the cabinet door pillar is installed, embed and adopt screw rod fastening spacing in the slotted eye and with hinge 2 further groove, depress connecting rod stay 3 again, simultaneously pulley 5 is put into pulley fixed head 6 and adopted the fastening location of screw rods that connecting rod is put into the pulley groove can to open overhead door.Its operation principle is as follows: when overhead door is opened, acting on pulling force on the connecting rod, to be subjected to pulley spacing to lower slider, the other end stage clip fixed mount of connecting rod pivot is moved upward, the stage clip pressurized produces tension force simultaneously, cause overhead door self-closing, when connecting rod stay projection slips over pulley, and the connecting rod projection returns and stopped by pulley, overhead door stops gear when opening 15 °, discharge the interior steam of cabinet once more to downward swing door, overhead door and door pillar form 90 ° of connecting rod tail end circular grooves and just in time snap in pulley groove, and just in time be the fixed position this moment, the self-closing power of overhead door less than the connecting rod circular groove upward to bearing pressure.Be overhead door open operation position, must manually upwards close the door after the operation just to make connecting rod circular groove disengaging pulley produce self-closing again.
