Description
Technical field
The utility model belongs to automatic close rotary door technical field, particularly a kind of mechanical positioner of preventing that door leaf from cutting out automatically of being used to.
Background technology
Existing rotary door door leaf usually is provided with the self closing device that door leaf cuts out automatically, the direction that the door leaf that self closing device can drive rotary door turns to door leaf to cut out around the jointed shaft of door leaf and doorframe, for example automatic rotating swinging door, the door leaf of opening cuts out under the effect of spring tension automatically, this can save the action of closing the door, but this needs door leaf to stay open state for continuously carrying article or other to make troubles during a period of time.
The positioner that a kind of antitheft door of building keeps opening-wide state in being the Chinese utility model patent manual of CN2878617Y, publication number is disclosed, described positioner is by supporting leg, the supporting leg seat, the supporting leg twisted axis, supporting leg off working state detent mechanism is formed, wherein the supporting leg seat comprises fixed head that is connected with door leaf and the axis hole plate that is vertically set on the fixed head, the supporting leg seat is fixed on door leaf inner surface bottom, and as far as possible away from the hinge axes of door leaf and doorframe, supporting leg is a rod member, lower end at supporting leg is installed with rubber pad, supporting leg is provided with and kicks ear, supporting leg is rotatably installed on the supporting leg seat by the supporting leg twisted axis, to the distance on ground, supporting leg off working state detent mechanism is the extruding retainer spring that is installed between supporting leg and the supporting leg seat to the length of supporting leg greater than twisted axis hole on the supporting leg seat.When above-mentioned positioner uses, door leaf is opened to needed degree, with the ear that kicks on the pedal supporting leg, put down supporting leg, the rubber pad of supporting leg lower end touches ground, and the thrust of the closing the door compressing supporting leg by the original closing device of building door produces makes supporting leg produce reaction force, two dynamic balances, thus make door leaf be parked in required open position.When needs at closing time, lift supporting leg with pin, make supporting leg rest on the inner surface of door leaf, the extruding retainer spring compresses an end of supporting leg, make the end that rubber pad is housed of supporting leg can not leave the door leaf inner surface, make supporting leg bring influence can for the normal use of door.
But above-mentioned positioner is not quite convenient in use, in the time will using supporting leg to locate door leaf, need earlier supporting leg to be put down, and because supporting leg is extruded the retainer spring extruding and is positioned near on the door leaf surface, people's pin is not easy to pedal and kicks ear and supporting leg is put down, and kicks the also not very good realization of action of ear with the pin hook.And the extruding retainer spring in the above-mentioned positioner only just can play the effect of extruding location when supporting leg is almost regained fully, and it is not convenient that supporting leg reclaims.
The utility model content
The purpose of this utility model is to provide a kind of mechanical positioner of preventing that door leaf from cutting out automatically of being used to, and reclaims not technical problem easily with the supporting leg that solves positioner in the prior art.
For achieving the above object, provided by the utility model being used to prevents that the mechanical positioner that door leaf cuts out automatically from adopting following technical scheme: a kind of mechanical positioner of preventing that door leaf from cutting out automatically of being used to, comprise and be used for the hinged seat of fixedlying connected with door leaf, on hinged seat, be hinged with supporting leg, one end of supporting leg is the hinged end that is hinged with hinged seat, the other end is to be used for contacting to realize the end that contacts to earth of door leaf location with ground, described positioner also comprises a spring base that is higher than described hinged seat when being used for use that door leaf is fixedlyed connected, between spring base and supporting leg, be provided with an extension spring, one end of extension spring is connected on the hinged seat, the other end is connected on the supporting leg, and the position that is connected with extension spring on supporting leg is near the hinged end that is hinged with hinged seat of supporting leg.
Described hinged seat and spring base one are installed in one and are used for the location-plate of fixedlying connected with door leaf.
Described supporting leg is tabular supporting leg, the position that is connected with extension spring on the described supporting leg be positioned at tabular supporting leg on the side of location-plate.
The end that contacts to earth of described tabular supporting leg be provided with the outstanding portion of contacting to earth that is used for contact with ground and be positioned at the portion's of contacting to earth one side be convenient to ride to open the stampeding section of tabular supporting leg, the end that is used to ride of stampeding section is the plane.
Described hinged seat comprises that one is installed in the fixed cover on the location-plate, the hinged end that is hinged with hinged seat on the tabular supporting leg is that one is installed in the turning set on the tabular supporting leg, be equipped with the jointed shaft with both coaxial settings in turning set and fixed cover, described fixed cover comprises the two sections hollow sleeve sections on the jointed shaft of being sleeved on that are distributed in the axial two ends of turning set.
The position that is connected with fixed cover on the described location-plate is to protrude in the set kink of location-plate, and the turning set opposite position place with tabular supporting leg on the described kink offers breach.
The beneficial effects of the utility model are: being used for of being provided in the utility model prevents that the mechanical positioner that door leaf cuts out automatically is provided with extension spring between spring base and supporting leg, one end of extension spring is connected on the spring base, the other end is connected on the supporting leg, like this when using this positioner, open supporting leg, contacting to earth of supporting leg held roof pressure on the ground, realization is closed to prevent door leaf automatically to the door leaf location, the open mode that the door leaf maintenance of rotary door needs, and when needs are closed door leaf, with pin supporting leg is kicked up, supporting leg reclaims rapidly under the effect of extension spring, does not influence normally closing of door leaf.The utility model is simple in structure, when being installed in positioner on the door leaf, has promptly effectively guaranteed the location to door leaf, has realized again can reclaiming supporting leg fast, easily when closing door leaf simultaneously, convenient use to rotary door.Because between spring base and supporting leg, extension spring is set in the utility model, and the position that is connected with extension spring on the supporting leg is near the hinged end that is hinged with hinged seat of supporting leg, like this after supporting leg is regained, because the effect of extension spring itself, will there be certain distance in contacting to earth of supporting leg between end and the door leaf, this distance can be convenient for people to open supporting leg with pin to the direction away from location-plate, has improved the practicality of positioner.
Supporting leg is designed to tabular supporting leg, can makes supporting leg attractive in appearance so on the one hand, can improve the rigidity of supporting leg on the other hand.
At the end that contacts to earth of tabular supporting leg the end being set is that tabular supporting leg can be convenient to open so that people when opening supporting leg, directly trample on the stampeding section with pin in the stampeding section on plane.
