Abstract
The invention provides a self-locking door body opening structure comprising a frame, fixed seats, an air cylinder, a dialing block, a shaft and a door body, wherein the frame is of a rectangular structure matched with a door body, the fixed seats are respectively arranged on beams at two ends of the frame, a strip hole is respectively formed on each fixed seat, two end parts of the door body are respectively provided with one inclined groove, two end parts of the door body are arranged on the fixed seats, and when the door body is closed, and an acute-angle inclined angle alpha exists between each inclined groove and each strip hole. The air cylinder is arranged on the beams, the air cylinder is connected with the dialing block, and the dialing block is hinged with the shaft; and the shaft is penetrates through the slidable strip hole on each fixed seat, and the end part of the shaft is arranged in each inclined groove of the door body. The self-locking door body opening structure drives the whole door body to be opened and closed due to the flexibility of an air rod of the air cylinder. The self-locking door body opening structure is low in structure height, so that the requirement to the installing height can be reduced; and the angle of each inclined groove on the door body is 8-15 degrees, and the self locking of a mechanism can be completely realized when the door body is closed, so that the mechanism is safe and reliable to control, the acting force of the air cylinder is reduced, and the service life of the air cylinder is prolonged.
Description
(1) technical field
The present invention relates to a kind of Men Ti open and close controlling mechanism, the door body Unclosing structure of specifically self-locking.
(2) background technology
Door body open closed is the Machine Design problem often running into, it is manual or pneumatic structure that the folding of ordinary circumstance Xiamen body is closed, wherein pneumatic structure can realize automation, general Pneumatic door-opening mode is carried out folding and is closed for directly hauling a body by cylinder rod, the feature of this structure is to implement than being easier to, shortcoming is to take up room greatly, if door is excessive, can cause folding completely or close a sub situation, require larger to the stroke of cylinder, height after Men Zi opens can not be less than the twice of cylinder stroke, if have External Force Acting on this door, strength has cylinder to bear completely, life-span at more severe working environment lower cylinder is lower.This structure has just overcome above-mentioned problem, and integral installation highly mainly rises certainly in the width of door body, and the life-span of cylinder extends greatly.
(3) summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, a kind of door body Unclosing structure of self-locking is provided, this structure has solved following three technical problems: first technical problem is that the requirement of existing door body setting height(from bottom) is too large, and second technical problem is that former door body cannot be realized self-locking; The 3rd technical problem is that on a body, bearing capacity carrys out balance by cylinder completely, and the cylinder life-span is short.
The technical solution adopted for the present invention to solve the technical problems is:
The door body Unclosing structure of self-locking, comprise framework, holder, cylinder, shifting block, axle and door body, described framework is the rectangle structure matching with door body, two long limits of framework are longeron, two minor faces of framework are crossbeam, on two end floor beams, be separately installed with holder, on holder, level offers the slip strip hole being used in conjunction with axle, and the both ends of door body are symmetricly set on holder by jointed shaft near outer side edges.Described cylinder level is arranged on crossbeam, on the gas bar of cylinder, is provided with shifting block, and shifting block and axle link together.The both ends symmetry of described door body offers valley gutter, and the slip strip hole on inner side and the holder of described valley gutter is in same level, and the outside of valley gutter is higher than the horizontal plane of slip strip hole, and above-mentioned valley gutter and slip strip hole are an acute angle angle α.
Described axle is through the strip hole that slides on holder, and its end is placed in the valley gutter of a body.
The acute angle angle α scope that described valley gutter and slip strip hole form is between 8-15 °, taking α as 12 ° as best.
On described door body, be provided with reinforcing rib, reinforcing rib is crisscross distribution on door body.Described door body both can adopt double swing doors, also can adopt single open-door structure, but while adopting single open-door structure, needed to adopt Rodless cylinder to drive.
The door body Unclosing structure of self-locking of the present invention, its operating principle is as follows:
The gas bar that promotes cylinder when external source of the gas stretches out, the shifting block band moving axis of gas bar by its end is along the horizontally outward lateral movement of slip strip hole on holder, because the end of axle is placed in the valley gutter of a body, axle is in moving horizontally laterally, under the effect of valley gutter, door body moves downward and opens centered by handing-over axle; Otherwise, in the time that external source of the gas promotes the gas bar indentation of cylinder, gas bar moves along the slip strip hole level on holder to the inside by the shifting block band moving axis of its end, because the end of axle is placed in the valley gutter of a body, axle is in moving horizontally to the inside, under the effect of valley gutter, door body moves upward and closes centered by handing-over axle.
Compared with prior art, the beneficial effect producing is the door body Unclosing structure of self-locking of the present invention:
The present invention is by the flexible folding that drives whole door body of gas bar of cylinder.Because the folding of door body is the promotion that is subject to the horizontal cylinder in left and right, so it is very flat that overall structure will become, reduce the requirement to setting height(from bottom), have material above door body time, the weight of material acts on a body, its gravity direction is for straight down, because the angle of the valley gutter on door body is 8-15 °, be less than the angle of friction of material itself, so realize the self-locking of mechanism completely, can not beat voluntarily opening door body even if material is very heavy, safe and reliable in mechanism controls process, and reduce the active force to cylinder, extended the life-span of cylinder.
